Description

Seeding machine for easy horizontal and position adjustment {SEEDING MACHINE}

The present invention relates to a planter that is easy to adjust horizontal and position.
[This study was carried out as a 2018 advanced production technology development project supported by the Ministry of Agriculture, Food and Rural Affairs and Technology, as a resource of the Ministry of Agriculture, Food and Rural Affairs. (Task number: 318002-3)]

The planter is a device for planting seeds in the field. The seeding machine generally includes a container for holding seeds, a seed dispensing hole formed at the bottom of the container, and a wheel to periodically withdraw seeds from the dispensing hole every predetermined distance while driving the soil floor. By installing the handle on the planter, a person can perform planting while pushing the planter directly. On the other hand, in the prior art, sowing was also carried out with a fertilizer spreader.

In recent years, the sowing machine is often used in combination with other agricultural implements installed at the rear of the tractor, such as a tractor or a cover mounted at the rear of the tractor. In some cases, a seed drill is installed and used in the rotor behind the tractor. The earthenware is a farm equipment that can form a dug of a certain shape and height. The soil cover was originally developed as a device for covering soil after sowing. The commercialized cover machine has a rotating blade and a cutting blade, and the cutting blade performs a function of preventing soil from being dug by the rotating blade from entering the valley. Therefore, it is possible to form a weir due to the cover, and the cover is often used for the purpose of soiling.

As such, in the trend of increasing use of combines with other farming equipment, the need for separating the binding state frequently after combining with other farming equipment has also emerged. This is because the shape of the seedling planting plant varies and the types of planting seeds vary. For example, when sowing corn seeds and when sowing barley seeds, the environment of sowing is different, so the optimum matching between the sowing machine for each case and other agricultural equipment may be different. In order to match different plants according to different planting environments, it is necessary to disengage the combines of the existing planters and recombine them with other farming devices.

When used in combination with other agricultural equipment attached to the rear of the tractor, the planter is not used alone, but is used with a plurality of planters attached to the lateral bar. As described above, in order to easily detach and attach to other farm equipment with a plurality of planters attached to the lateral bar, it is important to ensure easy workability of the detachment process and stable bonding force in the recombination state after detachment.

In addition, it is important to maintain the horizontal with the field to be planted in a state in which a plurality of planters are attached to the lateral bar. The horizontal state of the seed drill may be different for each attachment and detachment. The planter is to sow seeds by digging in the middle of the ground, so it is necessary to adjust the angle and keep it level with the ground. However, it is difficult to adjust the angle and level it because the condition of the farmland using the planter is different, the planters, the cover and the planter are different and various crops must be planted. Also, since it is not the same manufacturer, it is difficult to make everything together. It would be less of a problem if the planters were used only in a fixed condition without attaching and removing them from other farming equipment, but the level could be distorted in the process of attachment and detachment to various farming equipment. In addition, the condition of the field using the sowing machine may vary. It is important for satisfactory sowing that the planter is attached to other farming equipment and is easily leveled in the field to fit the condition of the field you are working on.

In addition, when a plurality of seeders are connected to the lifting cylinder in a state attached to the lateral bar, fast and accurate descending by the lifting cylinder becomes important. Since the planter is to plant seeds by slicing a bone in the ground, it is necessary for the lifting cylinder to quickly and accurately lower the planter to a desired height.

In the situation where a plurality of planters are connected to a bar and used in combination with other agricultural equipment, the prior art has not satisfied the above three requirements. First, the process of attaching and detaching to other farm equipment was cumbersome. Second, it was difficult to achieve a satisfactory leveling condition as well as taking a long time to recombine after desorption because it was necessary to level the attachment state during attachment and detachment because there was no function to precisely level it in combination with other farm equipment. . Third, in the prior art, when the seeding machine was lifted and operated by the lifting cylinder, the operator operating the lifting cylinder had to finely operate the cylinder hydraulic adjustment device to adjust the height at which the seeding machine was lowered, which was a obstacle to the rapid and accurate descending of the seeding machine. .

The third requirement, the operation of the lifting cylinder, will be further explained. It is necessary to adjust so that the seed drill does not hit the ground even at the maximum stroke of the cylinder. If the maximum stroke state of the cylinder is too long, when the elevator cylinder is operated to the maximum descending position by operation of the elevator cylinder, the seed drill may be damaged by hitting the ground. To adjust the cylinder mounting position to avoid this problem, it is necessary for the consumer to elaborate the cylinder position adjustment when mounting in the field, and it is difficult for the consumer to mount the cylinder while making this adjustment.

United States Patent Application Publication No. US2012/0316673 (2012.12.13.) Japanese Patent Publication No. 4948043 (2012.06.06.)

The above three requirements were not satisfied in the prior art. The object of the present invention is to solve the problems of the prior art and satisfy the above three requirements.

Seeder according to an embodiment of the present invention, each independently configured, the length of the adjustable pair of link 20 and the pair of connecting link 20 hinged to the horizontal bar 30 and, It includes a seeder unit 40 coupled to the transverse bar 30, each of the connecting link 20, two bars (bar, 21, 22) and the hinge points (23, 24) of both ends It includes a clamp portion (25, 26) is connected via, but the two bars (21, 22) is inserted into the other to allow the length to be adjustable through sliding, each of the connection link (20) The clamp part 26 is connected to the bar 22 and the lateral bar 30 through the hinge point 24, while the horizontal adjustment part hinged to the upper part of the bar 22 and the hinge point 61 By being hinged through 60 and the hinge point 63, when the two horizontal adjustment parts 60 are operated in the same way, the angle of the transverse bar 30 and the seeder unit 40 coupled thereto is adjusted. When the two horizontal adjustment units 60 are operated differently, the horizontal state of the horizontal bar 30 and the seeder unit 40 coupled thereto is adjusted, and the horizontal adjustment unit 60 is A three-section link structure consisting of three hinge points (24, 61, 64) is formed, and the length between the hinge point (61) and the hinge point (64) among the three hinge points (24, 61, 64) is In order to be adjustable, the lateral bar 30 is hinged to the lifting cylinder 50, and the lifting cylinder 50 has a pair of connection links 20 and excitations at the maximum stroke of the lifting cylinder 50 To limit the maximum descending height of the lateral bar 30 and the seeder unit 40 connected to, the cylinder lowering limit 70 is provided to facilitate horizontal and position adjustment.

In addition, additional configurations may be further included in the seed drill according to the present invention.

According to the present invention, the above three requirements are satisfied. More specifically, first, the desorption structure to other agricultural equipment is improved, so that the desorption process is easy and stable bond maintenance can be ensured. Second, since a function for precisely leveling in a state combined with other farming equipment is provided, a problem in the prior art that has to be leveled cumbersomely while correcting the attachment state during detachment can be solved. Third, thanks to the cylinder lowering limit, the maximum stroke of the cylinder can be easily adjusted, so that the seed drill can be quickly and accurately lowered to the optimum position.

Therefore, the following detailed description is not intended to be done in a limiting sense, and the scope of the present invention should be taken to cover the scope claimed by the claims of the claims and all equivalents thereto. In the drawings, similar reference numerals denote the same or similar components throughout several aspects.

Hereinafter, various preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings in order to enable those skilled in the art to easily implement the present invention.

Overall structure

1 is a photograph of an actual embodiment in which the planter 10 is connected to the rear of the tractor, and the seed drill according to an embodiment of the present invention is connected to the planter 10.

Referring to FIG. 1, a pair of connection links 20 are coupled to the cover 10 by a clamp structure. The clamp structure, which is one of the improvements of the present invention, will be described in more detail in FIG. 2. At the rear end of the pair of connection links 20, transverse bars 30 are coupled by a clamp structure. A plurality of seeder units 40 are mounted on the lateral bar 30 by a clamp structure. In the center of the transverse bar 30, a hinge structure is provided that engages the lifting cylinder 50. It can be clearly seen from FIG. 1 that the other end of the lifting cylinder 50 is hinged to the cover 10.

Link structure

2 is a view showing the structure of the connection link (20). According to FIG. 2, the connecting link 20 includes two bars (bars, 21, 22) and clamp portions (25, 26) connected via hinge points (23, 24) at both ends. The two bars (21, 22) is a structure in which one can be inserted into the other, and is fixed by a through hole in the inserted state. A plurality of through holes are provided. While adjusting the insertion depth, it is possible to fix the two bars 21 and 22 by inserting a bolt into the through hole, so that the length of the connection link 20 can be adjusted. The clamp part 25 is coupled to the cover 10. The characteristic structure of the clamp portion 25 is as follows.

First, the clamp portion 25 is an open structure. Due to this open structure, when coupled to the cover 10, the coupling part of the cover 10 can be mounted on each pipe in the transverse direction as it is, without separating the coupling part of the cover 10. Fixing in the mounted state can be securely achieved by fastening a plurality of fixing bolts provided at the ends of the open structure.

On the other hand, the clamp portion 25 has a structure in which its inner circumferential surface can be adapted to both square and circular pipes. Although the coupling portion of the cover 10 is implemented as a square pipe in the embodiment of FIG. 1, in some cases, the coupling portion of the cover 10 may be a circular pipe. Such a structure allows the planter according to the present invention to be easily connected to various types of cover 10.

The clamp part 26 performs a function of joining the transverse bar 30 that combines the seeder unit 40, and the fixed structure of the open structure is attached to the transverse bar 30. The point that is securely achieved by fastening a plurality of fixing bolts provided at the end is the same as that of the clamp portion 25.

Referring to FIG. 1, it can be seen that the seeder unit 40 in which a plurality is coupled to the transverse bar 30 is also achieved using a clamp having an open structure.

By performing the coupling through the clamps of the open structure identified through FIGS. 1 and 2, when it is necessary to separate the planters of the present invention for application to other crops, each part is easily separated and separated parts It is easy and robust to reunite.

Leveling structure

Hereinafter, a horizontal adjustment unit 60 which is another characteristic improvement point of the present invention will be described with reference to FIG. 2 as well.

The above-described horizontal adjustment part 60 is a hinge nut 61 hinged by a hinge point 61 formed on an upper part of the bar 22, and the cage nut 62 is opened through an opening provided at an end of the clamp 26. ) Is inserted into the long bolt (63). The long bolt 29 is "a" shaped, and a handle 65 is formed at the end.

The horizontal adjustment part 60 included in the seed drill according to the present invention is a three-section link structure formed by three hinge points, that is, the hinge points of reference numerals 24, 61, and 64. In this three-link structure, the length between the hinge point 61 and the hinge point 64 is adjusted. The adjustment method is achieved by adjusting the insertion depth of the long bolt 63 into the long nut 62 by turning the handle 65. When the long bolt 63 is inserted deeply into the long nut 62, the length between the hinge point 61 and the hinge point 64 is shortened, and the long bolt 63 is turned in the opposite direction to turn the long bolt 63 from the long nut 62. When pulled out, the length between the hinge point 61 and the hinge point 64 becomes long. Accordingly, the clamp portion 26 is rotated clockwise or counterclockwise around the hinge point 24, and the lateral bar 30 coupled to the clamp portion 26 can be lowered or lifted.

The above-described horizontal adjustment unit 60 is formed on both connection links. The distance between the hinge point 61 and the hinge point 64 is adjusted relative to the horizontal adjustment part 60 provided on the right connection link 20 by adjusting the horizontal adjustment part 60 provided on the left connection link 20. When lengthened, the lateral bar 30 sags to the left when viewed from the front, and relatively short sags to the right. Likewise, by adjusting the horizontal adjustment unit 60 provided on the right connection link 20, the distance between the hinge point 61 and the hinge point 64 is relatively long compared to the horizontal adjustment unit provided on the left connection link 20. When the lateral bar 30 is viewed from the front, it sags to the right, and when it is relatively short, it sags to the left. If both horizontal adjustment parts 60 are adjusted in the same way, the horizontal state does not change, and only the angle of the horizontal bar 30 to which the plurality of seeder units 40 are attached is adjusted. If the length of both horizontal adjustment parts 60 is equally short, the angle of the seeder units 40 can also be adjusted counterclockwise by turning the horizontal bar 30 counterclockwise when viewed from the left. If the lengths of both horizontal adjustment parts are equally long, the angle of the seeder units 40 can be adjusted clockwise by turning the horizontal bar 30 clockwise.

The structure of the above-described horizontal adjustment unit 60 and the implementation of the horizontal adjustment function may be more clearly understood with reference to FIGS. 3 to 5.

First, it will be described with reference to FIGS. 3 and 4. In the state of FIG. 3, the adjusted length between the hinge point 61 and the hinge point 64 is relatively long compared to the state of FIG. 4. In the actual embodiments of FIGS. 3 and 4, a display plate is attached to the long nut 62, and numbers 1 to 9 are displayed on the display plate. On the other hand, an indicator portion was integrally formed at the end of the clamp portion 26. In the actual embodiment of FIG. 3, the indicator indicates 5 of the numbers displayed on the display plate. In the actual embodiment of Fig. 4, the indicator indicates one of the numbers displayed on the display plate. By this configuration, the user can easily grasp the relative length adjustment state of the horizontal adjustment unit 60 described above.

3 and 4, the clamp nut 26 is interlocked with the action of the long nut 62 and the long bolt 63 to change the distance between the hinge point 61 and the hinge point 64, That is, the configuration in which the length of one side of the three-section link changes can be clearly identified. The important point here is that the scope of the present invention is not limited to the structure of the actual embodiments of Figs. 3 and 4, as long as the horizontal state of the lateral bar 30 connected to both connection links 20 can be changed by individually adjusting the length of one side in the three-link structure provided on both connection links 20 In addition to the structure of the actual embodiment, any number of structures may be included in the scope of the present invention.

From FIG. 5, the state of the actual embodiment in which the horizontal state is adjusted can be confirmed. From FIG. 5, when viewed from the front, the left connection link sags down, and the right connection link can see the appearance of the planter. In this operating state of FIG. 5, the length between the hinge point 61 and the hinge point 64 of the horizontal adjustment part 60 provided on the left connection link is provided at the hinge point 61 of the horizontal adjustment part 60 provided on the right connection link. ) And the hinge point 64 are adjusted to be relatively longer than the length. One side of the length-adjustable three-section link is the downlink of the side of the long-adjusted side. Conversely, one side of the adjustable length three-way link, the link of which is adjusted to the shorter side, goes up.

Cylinder lower limit structure

Hereinafter, the structure of the cylinder lowering limit portion 70, which is another characteristic improvement of the present invention, will be described.

The lifting cylinder 50 has one end hinged to the cover 10 and the other end hinged to the transverse bar 30. In such a combined state of the lifting cylinder 50, the cylinder lowering limit 70 is installed in parallel with the lifting cylinder 50 on the lifting cylinder 50. The mutual installation state of the lifting cylinder 50 and the cylinder lowering limit 70 can be clearly confirmed with reference to FIG. 1.

6 is a view showing the cylinder lower limit 70, from which the specific structure of the cylinder lower limit 70 can be seen. The cylinder lowering limit portion 70 includes a bar (71) and a long bolt (72) in which a longitudinal hollow portion is formed and a through hole is formed at one end. The long bolt 72 is formed in the hinge connection portion 73 with the transverse bar 30 and is inserted into the opening 74 with a thread formed therein. In addition, the long bolt 72 extends into the bar 71 through the through hole 75 of the bar 71. A thread is not formed in the through hole 75. A fixing nut 76 is formed at an end portion extending into the bar 71 of the long bolt 72. A handle 77 is formed at an end opposite to the fixing nut 76 of the long bolt 72.

The length of the insertion of the long bolt 72 into the bar 71 can be adjusted by rotating the handle 77 to rotate the long bolt 72 clockwise or counterclockwise. This adjustment state can be confirmed from FIG. 4. 4 is a view for explaining the operating principle of the cylinder lowering limit (70).

The upper part of FIG. 7 shows a state in which the relative insertion depth of the long bolt 72 into the bar 71 is long. At this time, the stroke length of the lifting cylinder 50 is L1. When the fixing nut 75 mounted on the end of the long bolt 72 comes into contact with the through hole 75 of the bar 71, no further stroke occurs, and thus the stroke is limited. The lower part of FIG. 7 shows a state in which the relative insertion depth of the long bolt 72 into the bar 71 is short. At this time, the stroke length of the lifting cylinder 50 is L2. Likewise, when the fixing nut 75 mounted on the end of the long bolt 72 comes into contact with the through hole 75 of the bar 71, no further stroke occurs, so the stroke is limited.

It can be clearly confirmed from FIG. 7 that the stroke of the elevating cylinder 50 can be adjusted long (L1) or short (L2) by adjusting the insertion length of the long bolt 72 into the bar 71.

The lifting cylinder 50 pushes or pulls the piston by hydraulic operation. One end of the lifting cylinder 50 is mounted on the cover 10, and the piston end is connected to the transverse bar 30 joining the plurality of seeder units 40. When the lifting cylinder 50 contracts, the connecting link 20 and the lateral bar 30 and the plurality of seeder units 40 connected thereto rise, and when the lifting cylinder 50 expands, the connecting link 20 and The transverse bar 30 and the plurality of seeder units 40 connected thereto descend. The cylinder lowering limit part 70 limits the length at which the piston of the lifting cylinder 50 is pushed to the maximum, that is, the maximum stroke, thereby increasing the descending height of the connecting link 20, the transverse bar 30, and the seeder units 40. Adjust. The maximum descending height of the link 20, the transverse bar 30, and the seeder units 40 can be easily adjusted by the cylinder lowering limit 70, which is a characteristic structure of the present invention.

The effect achieved by the cylinder lowering limit 70, which is a characteristic structure of the present invention, will be additionally described. Even when the cylinder stroke remains, it is possible to limit the cedar units 40 so as not to be damaged by hitting the ground and stopping at an optimal height. On the other hand, according to the cylinder lowering limit portion 70 of the present invention, it is also possible to increase the stroke. After mounting the lifting cylinder 50 by making the cylinder stroke longer than necessary, use it for A by restricting it, and when switching to B use requiring more stroke, release the mounting state of the lifting cylinder 50 to make it longer The stroke can be lengthened by simple operation without re-installation according to the stroke.

In contrast to the embodiment of FIG. 1 and the embodiment of FIG. 8, only the structure of the clamp 25 mounted on the rear end of the connection link 20 is changed, and the rest of the structure is completely the same.

9 and 10 is a picture of the actual operating state lifted by the contraction of the lifting cylinder 50 in a state in which the seeding machine according to the present invention is connected to the cover 10 and the rotor 80, respectively. When the piston is pushed by supplying hydraulic pressure to the elevating cylinder 50 from the contracted state of the elevating cylinder 50, the seed drill lifted is lowered as the piston advances. It should be understood that the maximum descending height of the elevating cylinder 50 can be easily adjusted by the function of the cylinder lowering limit 70 described above. All of the photos of the actual embodiment included in this specification reveal that they were taken at the applicant's factory where access was controlled prior to filing of the present invention.
