Description

[0001]
[Industrial application fields]
The present invention relates to a transverse feed chain conveyor.
[0002]
[Prior art]
Conventionally, a supply port is provided on the upper surface of one end of the case, and a discharge port is provided on the lower surface of the other end. The drive-side sprocket provided on the other end of the case and the passive-side sprocket provided on one end of the case are spaced apart from each other. A cross feed chain conveyor in which a conveyor chain with a transfer plate attached is wound is known.
[0003]
[Problems to be solved by the invention]
The known example has a problem that when a grain is supplied from a supply port, a part of the input grain is sandwiched between a chain and a sprocket and is crushed.
For this reason, there has been a method in which the supply port is provided close to the other end, but the known example has a problem that the whole is long and large.
Moreover, although a cleaning brush may be provided in the moving path of a conveyor chain, in the case of a brush, hair removal may mix with grain and is not preferable.
[0004]
OBJECT OF THE INVENTION
Prevention of grain crushing phenomenon, downsizing of the entire device, prevention of foreign matter from entering the grain.
[0005]
[Means for Solving the Problems]
Therefore, according to the present invention, the supply port 2 is provided on the upper surface of one end of the case 1, the discharge port 3 is provided on the lower surface of the other end, and the passive sprocket is provided on one end side of the case 1 at a predetermined interval from the supply port 2. 5, the drive side sprocket 4 is provided on the other end side of the case 1, and a conveyor chain 6 is wound around the passive side sprocket 5 and the drive side sprocket 4, and the transfer plate is spaced from the conveyor chain 6 at a predetermined interval. 10 is attached to the conveyor chain 6 so that the transfer plate 10 moves from the drive side sprocket 4 to the upper side in the case 1 and is reversed by the passive side sprocket 5 to transfer the grain in the case 1 to the other end of the case 1. rotates and moves to convey to the discharge port 3 provided on the lower surface, the upper position than the conveyor chain 6 to move upward in the supply port 2 from the end side, blowing the grain of the engagement groove 9 of the passive sprocket 5 It is obtained by the crossfeed chain conveyor which is disposed an air nozzle pipe 11 which are capable of.
[0006]
【Example】
An embodiment of the present invention will be described with reference to the drawings. 1 is a horizontally long metal or wooden case, 2 is a supply port provided on the upper surface of one end of the case 1, 3 is a discharge port provided on the lower surface of the other end of the case 1, A drive sprocket 5 provided on the other end side is a passive sprocket provided on one end side of the case 1, and a conveyor chain 6 is wound around the drive sprocket 4 and the passive sprocket 5.
[0007]
The conveyor chain 6 is formed by connecting a metal link 7 and a resin link 7 a having a certain length one after another with pins 8, and pins 8 are formed in the engagement grooves 9 of the drive side sprocket 4 and the passive side sprocket 5. Engage and rotate the conveyor chain 6. Transfer plates 10 are attached to the conveyor chain 6 at regular intervals.
At this time, if the resin link 7a is used, the transfer plate 10 can be easily attached.
[0008]
Thus, when the conveyor chain 6 is rotated and the grains are laterally transferred in the above, the grains engaged with the engaging grooves 9 of the passive sprocket 5 may be bitten by the pins 8 in order to prevent this. In the present application, an air nozzle tube 11 is disposed in the vicinity of the passive sprocket 5. Reference numeral 12 denotes a plurality of nozzles provided in the air nozzle tube 11.
[0009]
Since the air nozzle tube 11 blows off the grains engaged with the engaging grooves 9, a brush or the like can be used instead. However, in the case of a brush, hair may be removed and mixed with the grains, which is not preferable. . The air nozzle tube 11 is preferably attached so as to blow wind in the grain transfer direction as much as possible. The number of the air nozzle tubes 11 is arbitrary.
[0010]
Further, the passive sprocket 5 may be a roller having no engagement groove 9. In the case of the roller as well, since the grains entering between the left and right links 7 and the rollers are crushed by the pins 8, Grain that has entered between the link 7 and the roller is blown.
[0011]
Thus, a blower (blower) 14 is connected to the air nozzle pipe 11 via a connection hose 13, and an opening / closing valve 15 is provided in the blowing path from the blower 14 to the air nozzle pipe 11. 15 may be interlocked with turning on and off of the drive side sprocket 4.
[0012]
The blower 14 is constituted by a blower or a compressor.
In the figure, 16 is a chain guide rail of the conveyor chain 6 moving on the upper side, and 17 is a scraper for bringing grain in the case 1 together.
[0013]
[Action]
Next, the operation will be described.
Since the present application has the above-described configuration, when the grain is supplied from the supply port 2, it is laterally fed by the rotating transfer plate 10 and discharged from the discharge port 3.
At this time, the conventional product has a defect that the grain supplied from the supply port 2 is engaged with the engagement groove 9 of the passive sprocket 5 and crushed by the pin 8. Since the air nozzle tube 11 is provided in the vicinity of the, the grains engaged with the engaging groove 9 are blown away and the drawbacks are solved.
In addition, since it is not cleaning with a brush, there is no possibility that hair removal mixes with grain.
Moreover, the supply port 2 can be provided close to the passive sprocket 5 side, the length of the entire case 1 can be shortened, and the entire size can be reduced.
[0014]
Thus, a blower 14 is connected to the air nozzle pipe 11 via a connection hose 13, and an opening / closing valve 15 is provided in the blowing path from the blower 14 to the air nozzle pipe 11. Since it is interlocked with the rotation of the side sprocket 4, the air nozzle pipe 11 blows and blows the grains when the conveyor chain 6 is rotating. Therefore, labor saving can be achieved.
[0015]
【effect】
The present invention, a supply port 2 on one end top surface of the case 1, the outlet 3 at the other end the lower surface respectively provided, a passive sprocket 5 on one end side of the case 1 at a predetermined distance of an end side of the supply port 2 The drive side sprocket 4 is provided on the other end side of the case 1, and a conveyor chain 6 is wound around the passive side sprocket 5 and the drive side sprocket 4, and a transfer plate 10 is placed on the conveyor chain 6 at regular intervals. mounting, said conveyor chain 6, the grain of the transfer plate 10 is inside the case 1 is inverted by the passive sprocket 5 by moving the upper inside the case 1 from the drive sprocket 4 on the other end the lower surface of the case 1 Rotating and moving so as to convey to the discharge port 3 provided, the grain in the engagement groove 9 of the passive sprocket 5 is blown to a position above the conveyor chain 6 that moves on the upper side from the supply port 2. U Since the air feed pipe conveyor is provided with the air nozzle pipe 11, the air nozzle pipe 11 is provided in the vicinity of the passive sprocket 5, so all the grains engaged with the engagement groove 9 are blown away. The grain crushing phenomenon can be prevented and a good grain can be obtained.
