Description

Auxiliary devices for mulching cultivation

technical field

The present invention relates to an auxiliary tool for mulch cultivation used when cultivating vegetables or fruit trees with a mulch sheet. Auxiliary equipment for mulching cultivation.

Background technique

Conventionally, as such an appliance, there is an appliance described in Patent Document 1, for example.

In this existing product, a pointed portion is provided at one end of the hollow tube, and many through holes are perforated on the tube wall of the hollow tube. In addition, this conventional product is formed so that a tank (tank) into which liquid fertilizer or agricultural chemicals enter can be connected to the upper end of the hollow tube.

In addition, a device in which a funnel-shaped cup is attached to the upper end of a tubular insertion body is also known (for example, refer to Patent Document 2).

Conventionally, as a method of plant cultivation such as vegetables, there is a cultivation method of covering a ridge (acre bed) with a plastic film. According to this film mulching cultivation method, not only can the ground temperature be raised to promote the growth of plants and increase yield, but also can suppress the evaporation of water in the soil, so cultivation in dry season is easy. In addition, the plastic film mulching cultivation method has the following advantages: it can prevent the loss of fertilizer, it is difficult to grow weeds, so the work of removing weeds can be omitted, and in addition, it can prevent the adhesion of pathogenic bacteria, so it can suppress diseases, and for example, when the plastic film is made silver , can prevent aphids and the like from flying. Therefore, plastic film mulching cultivation is most suitable for open-air cultivation or cultivation during low temperature periods.

However, in this cultivation method, since the ridges are covered with a mulch film, it is inconvenient to remove the film or use small holes for planting the seedlings when topdressing or watering operations are performed.

Therefore, conventionally, in the case of such a cultivation method, there is a problem that topdressing work or watering work cannot be easily performed, and man-hours are required for such work.

In addition, in the mulching cultivation method, since the ridges are covered with mulch, rainwater cannot penetrate the ridges, and therefore, there is a problem that it is difficult to permeate the soil with the components of the fertilizer even if topdressing is applied from the planting holes of the seedlings.

Then, in the conventional product described in Patent Document 1, since the hollow tube is filled with fertilizer, the fertilizer is accumulated in a narrow space, and the fertilizer is difficult to dissolve. In addition, in the case of this conventional product, it is a structure in which fertilizer seeps out from the through-hole of the peripheral wall of a hollow tube. Therefore, according to this configuration, it cannot be avoided that the fertilizer does not spread and stays in a narrow range around the hollow tube.

In addition, although this existing product can inject liquid fertilizer from a tank, it cannot make solid fertilizer, for example, use rainwater to topdress slowly over a long period of time.

Therefore, it is not suitable to utilize this existing product in the mulching cultivation method.

In addition, if the existing product described in Patent Document 2 is used to add solid fertilizer to the funnel-shaped cup for topdressing, it cannot prevent the fertilizer from deteriorating due to direct sunlight, or being eaten by birds and animals, or being polluted by heavy rain such as torrential rain. Fertilizer scatter from the cup body.

Therefore, even if this conventional product is inserted into a ridge covered with a mulch, for example, scattered manure flows along the surface of the mulch, and as a result, it is impossible to reliably topdress the ridge.

Contents of the invention

The present invention has been made in view of these problems of the prior art.

Therefore, the technical problem that the present invention intends to solve is to provide an auxiliary device for mulching cultivation that is formed as follows: it can easily and reliably penetrate fertilizers or chemicals into the ridges covered by mulching in a wide range to perform topdressing, etc. , In addition, it can prevent the deterioration of fertilizers, etc., prevent birds and beasts from stealing fertilizers, etc., and prevent fertilizers from scattering due to rainfall, and can also help to fix the mulch.

In order to solve the above-mentioned problems, the present invention employs the following technical means.

That is, the present invention is characterized in that, as shown in FIG. The prong-shaped part 4 is formed, and on the lower surface 1a of the container part 1, an indentation part 7 is formed in a high platform (Japanese "high platform") shape around the prong-shaped part 4, and the indentation part 7 is pressed into the ridge platform 6 through the plastic film 5, A through-hole 1c is formed in the bottom 1b of the container part 1 within the range surrounded by the press-fit part 7, and the inside and outside of the container part 1 are formed to communicate via the above-mentioned shielding part 3 (claim 1).

In the case of the present invention, the container part 1 is formed in the shape of a shallow plate or bowl, but its depth and shape are free. The shape of the shielding portion 3 is also free, and is not limited to the case of forming the umbrella shape shown in the figure. In addition, in the present invention, the shape, length, and thickness of the prong-shaped portion 4 are also arbitrary.

In addition, here, the raised platform shape means the shape in which the press-fit part 7 protrudes downward from the lower surface 1a of the container part 1 like the leg part of a tea bowl etc. FIG. Normally, the press-fitting portion 7 is preferably formed continuously so that it can be pressed in without breaking the mulch 5 , but the present invention is not limited thereto, and may be formed intermittently.

In addition, for the press-fit part 7, generally, the longer (higher) the protruding length (height) and the thicker the thickness, the more the mulch film 5 can be pressed into the ridge 6 during press-fit, so that the hole-shaped opening opened by the prong-shaped part 4 8 (refer to FIG. 6 ) is pulled outward to expand, but the length of the press-fit portion 7 may be appropriately selected in consideration of the cross-sectional shape, thickness, etc. of the prong-shaped portion 4 . In addition, in the case of the present invention, the press-fit portion 7 is generally preferably formed in an annular shape with the same axis as the prong portion 4, but is not limited thereto.

In addition, in the case of the present invention, the through-hole 1c is usually formed in plural numbers, but the number is arbitrary, and may be formed in a slit shape. In addition, here, forming the inside and outside of the container part 1 in a connected state through the shielding part 3 means that the shielding part 3 is formed so that the container 2 such as fertilizer or medicine can be prevented from deteriorating due to direct sunlight or the like by the shielding part 3. It may be scattered due to heavy rain, or eaten by birds or animals, and water can be poured into the container part 1 to collect rainwater and the like. Specifically, as shown in FIG. 1 etc., the shielding portion 3 is formed into an umbrella shape, and its diameter is formed to be slightly shorter than the diameter of the container portion 1, and a gap S is formed around the shielding portion 3, or, as shown in FIG. 8 As shown, the shielding part 3 is formed into a cover shape, and a vent part 3c is formed on the upper surface, or a notch is formed around it, thereby achieving this.

In addition, the product of the present invention is preferably integrally formed of corrosion-resistant materials such as plastics, but it can also be formed by assembling components by means of bonding or the like.

In addition, in the present invention, it is preferable that the upper surface of the shielding portion 3 is formed in a flat shape (claim 2).

The reason for this is that, for example, the palm of the hand can be placed on the shielding portion 3 , so that the insertion can be easily performed without tools.

In addition, in the present invention, as shown in FIG. 8 , it is preferable that the shielding portion 3 is detachably formed on the container portion 1 (claim 3).

The reason is that, thereby, the shielding part 3 can be detached, and the contents 2 such as fertilizer can be put into the container part 1, or water can be poured into the container part 1, and such operations can be easily performed.

In this case, in the present invention, preferably, as shown in FIGS. At the center position of the bottom surface, an embedding part 9 is erected in a state concentric with the axis of the prong-shaped part 4, and the embedding part 9 has a vertical hole 9a for the above-mentioned shaft 3b1 to be embedded at the axial center position, covering The lower surface 3a of the part 3 abuts against the upper end surface 9b of the fitting part 9 when fitting in (claim 4).

The reason for this is that water can be efficiently collected by being introduced into the container portion 1 from the peripheral edge of the lid 3 a when it rains or the like. In addition, thereby, the shaft 3b1 of the shielding portion 3 is not damaged, and the pressing force applied to the shielding portion 3 is transmitted to the prong-shaped portion 4 without loss, thereby enabling easy insertion into the ridge 6 .

In addition, in the present invention, it is preferable that the press-fit portion 7 is formed in an annular shape centering on the axis of the prong portion 4 (claim 5).

This is because, thereby, the hole-shaped opening 8 (see FIG. 6 ) opened by the prong-shaped portion 4 can be pulled outward in a well-balanced range of 360 degrees to expand.

Invention effect

In the present invention, on the lower surface of the open upper surface of the container portion, the pressing portion pressed into the ridge via the mulch is formed in a high platform shape around the prong-shaped portion, and the container portion is within the range surrounded by the pressing portion. A through hole is formed on the bottom.

Therefore, according to the present invention, it is possible to simply and easily perform topdressing or the like on a ridge covered with a plastic film using rainwater or the like without removing the plastic film or using a planting hole for the seedling.

In addition, in the present invention, since the press-fitting portion draws the mulch into the ridge, the hole-shaped opening opened by the prong-shaped portion can be pulled outward to expand. In addition, in this case, since the press-fit part functions as a water-retaining sheet pile, leakage of dissolved fertilizer can be prevented.

Therefore, according to the present invention, fertilizer and the like can be reliably infiltrated into the ridge from the opening, and topdressing and the like can be performed over a wide range from above.

In addition, in the present invention, the inside and the outside of the container part are formed in a continuous state through the shielding part.

Detailed ways

Hereinafter, a preferred embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1 and the like, the present invention consists of a container portion 1 with an open upper surface, a shielding portion 3 covering the contents 2 of the container portion 1, and a prong-shaped portion 4 that hangs down on the lower surface 1a of the container portion 1. form. In addition, the product of the present invention of this embodiment is formed of plastic.

The above-mentioned container part 1 is formed in the disk shape of a shallow bottom circle in this embodiment. In the present invention, a press-fitting portion 7 that is press-fitted into the ridge 6 via the mulching film 5 is formed on the lower surface 1 a of the container portion 1 . The press-fitting portion 7 is formed in a raised platform shape around the prong-shaped portion 4 , and is formed in a ring shape around the axis of the prong-shaped portion 4 in the present embodiment.

In addition, in the present invention, a plurality of through-holes 1c are formed on the bottom 1b of the container portion 1 within the range surrounded by the press-fit portion 7 . In the case of this embodiment, the prong-shaped portion 4 is formed in a cross pile shape as shown in FIG. 2 and the like. Further, as shown in FIG. 5 and the like, the through-hole 1c is formed around the cross-shaped protruding piece 4a of the prong-shaped portion 4 along the shape of the protruding piece 4a.

Moreover, in this embodiment, the shielding part 3 is provided with the support shaft 3b in the center of the lower surface 3d of the circular cover 3a, and is formed in umbrella shape. The lid 3 a is formed to have a diameter slightly shorter than that of the container portion 1 so as to form a gap S with the peripheral wall 1 d of the container portion 1 . The product of the present invention in this embodiment communicates the inside and outside of the container part 1 through the gap S mentioned above. Therefore, in the case of the product of the present invention, when water is poured with a watering can or the like or there is rainfall, water flows into the container portion 1 from the upper surface of the cover 3a through the peripheral edge of the cover 3a.

In addition, in the case of this embodiment, the upper surface of the cover 3a is formed in a flat shape so that it can be easily attached to the palm. In addition, the support shaft 3b is positioned and fixed to the bottom surface of the container portion 1 so that the axis thereof is concentric with the axis of the prong portion 4 .

Next, usage examples and effects of the present invention will be described. First, the operator slightly inserts the end (lower end) of the prong-shaped part 4 into the ridge 6 covered by the plastic film 5 (see FIG. platform 6 to the root (refer to FIG. 6 ).

Therefore, in the present invention, before the prong-shaped part 4 is inserted into the root, the lower end of the press-fit part 7 is in contact with the mulch 5. After the prong-shaped part 4 is inserted into the root, as shown in FIG. 5 is pressed into the ridge platform 6.

In this case, the press-fitting portion 7 is formed so as to surround the prong-shaped portion 4 as described above, and in this embodiment, is formed in an annular shape around the axis of the prong-shaped portion 4 . Therefore, the hole-shaped opening 8 of the mulch 5 opened by the prong-shaped part 4 is pressed into the length of the ridge 6 with the press-fit part 7 (twice the height H of the press-fit part 7 (refer to FIG. 6 ) and the press-fit part 7). In the present embodiment, the thicknesses T (refer to FIG. 6 ) of the entry portion 7 are uniformly pulled outward over a range of 360 degrees to expand.

Next, the operator puts, for example, fertilizer as the container 2 into the container unit 1 . When an operator pours water into the container part 1 or when there is rainfall, the fertilizer dissolves and flows out from the through hole 1c in the bottom 1b of the container part 1 . In this case, in the product of the present invention, the hole-shaped opening 8 opened by the prong-shaped portion 4 is expanded by the press-fit portion 7 as described above. In addition, in the case of the present invention, the lower surface 1 a of the container part 1 is in close contact with the mulching film 5 , and the press-fit part 7 functions as a sheet pile for retaining water. Therefore, according to the product of the present invention, the liquefied fertilizer does not flow out along the surface of the mulch film 5, but reliably penetrates into the ridge platform 6 from the above-mentioned opening 8, and spreads downward.

Therefore, in the case of the present invention, the fertilizer or medicine as the container 2 is covered by the shielding portion 3 . Therefore, according to the present invention, fertilizers and the like do not deteriorate due to direct sunlight. In addition, since the shielding portion 3 becomes an obstacle, the contents 2 will not be eaten by birds and animals. In addition, in the case of the present embodiment, the shielding portion 3 is formed in an umbrella shape, and communicates the inside and the outside of the container portion 1 through the surrounding gap. Therefore, in the case of the present invention, when pouring water with a watering can or the like or when it rains, the shielding part 3 functions as an umbrella, and water falls from the periphery of the lid 3a into the container part 1. Therefore, according to the present invention, it is possible to collect water efficiently and reliably. rainwater etc.

Among the above, in the present invention, the shielding portion 3 may be formed so as to be detachable from the container portion 1 . In this case, fertilizer and the like can be put in in a state where the upper surface of the container part 1 is completely opened by removing the shielding part 3 . Therefore, according to the present invention, there is an advantage that operations such as supplying and replenishing fertilizers, chemicals, or water can be easily performed.

Specifically, for example, as shown in FIG. 8 , it is realized by forming the shielding portion 3 in a cover shape and forming it so as to be able to engage with the upper edge of the peripheral wall 1 a of the container portion 1 . In the case of this embodiment, the ventilation part 3c is formed in the shape of a small hole or a slit at an appropriate position on the upper surface of the shielding part 3, and is formed so that the inside and the outside of the container part 1 can communicate with each other through the ventilation part 3c.

In addition, the attachment and detachment structure of the shielding part 3 can also be formed as shown in FIGS. 9-12.

In this invention, the shielding part 3 is formed in the shape of an umbrella so that the lower end is open and the shaft 3b1 is provided at the center of the lower surface 3d of the cover 3a. Furthermore, a fitting portion 9 having a vertical hole 9a into which the shaft 3b1 is fitted at the axial center position is provided in a standing shape at the center position of the bottom surface of the container portion 1 .

In this case, the axial center of the fitting part 9 is set to be the same as the axial center of the prong-shaped part 4 . Moreover, the shielding part 3 is formed so that the lower surface 3d (refer FIG. 10, FIG. 12) of the cover 3a may abut the upper end surface 9b of the fitting part 9 at the time of fitting.

Therefore, in the present embodiment, when the lid 3a is pressed from above, excessive force is not applied to the shaft 3b1 and the shaft 3b1 is not damaged. In addition, according to this structure, the pressing force can be efficiently transmitted to the prong 4 without loss, and the product of the present invention can be inserted into the ridge 6 .
