Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a fertilizer supply device in a fertilizer applicator that applies paste fertilizer to a field.

(b) Prior art Conventionally, fertilizer is supplied in a fertilizer applicator for paste fertilizer by lifting the fertilizer container and letting the paste fertilizer inside flow directly into the fertilizer tank, or by first transferring it from the fertilizer container to a bucket, etc. It was flowing into the fertilizer tank.

(c) Problems to be Solved by the Invention Among the fertilizer supply methods in the known fertilizer applicator, the method of directly supplying the fertilizer from the fertilizer container to the fertilizer tank does not allow the paste-like fertilizer to flow into the fertilizer tank.
The fertilizer containers had to be continually lifted by hand, which was extremely hard work, and the fertilizer leaked and wasted, and the leaked fertilizer got on clothes.

In addition, the method of transferring paste fertilizer once into a bucket is easier to hold than a fertilizer container when it is flowing into a fertilizer tank, but it is cumbersome as transfer is a two-step process, and leakage occurs each time.

(d) Means for Solving the Problems The present invention provides a fertilizer applicator that applies paste fertilizer in a fertilizer tank to a fertilizing section using a pump to apply fertilizer to a field, in which a fertilizer bag is placed horizontally in the fertilizer tank. By providing a space for storing the fertilizer and adding an extrusion device that presses out the paste fertilizer in the fertilizer bag to the pump side, the paste fertilizer can be put into the fertilizer tank while still in the fertilizer bag, and then pushed by the extrusion device. This eliminates the need for manual supply operations and solves the aforementioned problems.

(e) Action When paste fertilizer is placed in a fertilizer tank while still in a fertilizer bag and opened, or when the bag is opened and then placed in the fertilizer tank and the machine is moved forward and the pump is driven, the paste is stored in the fertilizer tank. The paste-like fertilizer in the fertilizer bag is extruded one by one by an extrusion device,
A pump forces this to the fertilization section and fertilizes it.

When the paste fertilizer in the fertilizer bag is used up, the empty fertilizer bag is taken out from the fertilizer tank and replaced with a fertilizer bag containing paste fertilizer.

(F) Embodiment To explain a riding fertilizing rice transplanter according to an embodiment of the present invention shown in the drawings, 1 is a vehicle body having front wheels 2, 2 and rear wheels 4, 4 pivotally supported by swing chain cases 3, 3. With engine 5 installed in the front,
A planting device 7 with a fertilizing pipe 6 attached to the rear portion serving as a fertilizing section is mounted so as to be movable up and down by an upper link 8 and lower links 9, 9, and a pump 10 provided on the side of the vehicle body 1 is installed. It is driven via a shaft 12 from a planting transmission case 11 and a transmission case 13.

A fertilizer tank A is installed on both sides of the driver's seat 14 with the bottom part of the fertilizer tank A connected to a sub-tank B (approximately the same capacity as a conventional fertilizer tank) with a suction hose 15, and the suction port of the pump 10 is It is connected to the sub-tank B by an introduction hose 16 having a distribution part, and the discharge port is connected to the fertilization pipe 6 by a pressure feed hose 18 having an indicator 17 in the middle.

Further, the fertilizer tank A has a flat bottom and an open top, and the housing of the extrusion device C has a flat top and an open bottom so that it overlaps the top of the fertilizer tank A. , one side of which is hinged to one side of the fertilizer tank A so as to be openable and closable, and the other side is detachably fixed with a clamp.

Furthermore, the extrusion device C is operated in the front and rear direction (fertilizer bag 41
An extrusion roller 27 is housed in the fertilizer tank A, which pushes out the paste-like fertilizer in the fertilizer bag 41 stored horizontally in the fertilizer tank A by rolling from the bottom side toward the outlet side of the fertilizer tank A. The fertilizer bag 41 is made of synthetic resin, and when feeding it, after opening the extrusion device C, the fertilizer bag 41 is
1 into the fertilizer tank A, then remove the lid of the outlet and fit it to the upper end of the suction hose 15. If the sub-tank B is empty in this state, the paste-like fertilizer in the fertilizer bag will be transferred to the sub-tank B. When the fertilizer flows in and becomes full, the paste-like fertilizer in the sub-tank B is pressurized and the suction action of the pump 10 is facilitated.

When the sub-tank B is full, the paste-like fertilizer in the sub-tank B is sucked by the pump 10 and discharged toward the fertilization pipe 6, and the paste in the fertilizer bag 41 stored in the fertilizer tank A is The shaped fertilizer is extruded into the sub-tank B by the extrusion roller 27 in the same manner as described above.

In addition to the above-mentioned roll extrusion method, the extrusion device C can also use an equivalent means such as a method of extruding by sequentially rolling up a tube from the bottom side, like toothpaste in a tube commonly used at home. May be adopted.

In addition, since the paste fertilizer in the sub-tank B is applied from the time the paste fertilizer in the fertilizer bag 41 runs out until it is replenished, there is no need to interrupt the work in the middle of the fertilization process. If the remaining fertilized area is small, it is possible to fertilize what remains in sub-tank B without replenishing it.

(g) Effects of the Invention As described above, the present invention provides a fertilizer applicator that uses the pump 10 to pump paste fertilizer in a fertilizer tank A to a fertilizing section to apply fertilizer to a field, in which a fertilizer bag is placed in the fertilizer tank A. A space for horizontal storage is provided, and an extrusion device C is provided to push out the paste fertilizer in the fertilizer bag 41 to the pump 10 side, so the paste fertilizer can be put into the fertilizer tank together with the bag, unlike the conventional method. This eliminates the need to hold the fertilizer bag 41 in your hand and let it flow into the fertilizer tank, and also prevents the paste from leaking and wasting it during the replenishment process, or from getting it on your work clothes. Adhesion can be reliably prevented.
