Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a fertilizer supply device in a fertilizer applicator that applies paste fertilizer to fields.

(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.

Additionally, if the paste fertilizer in the fertilizer tank runs out midway through the fertilization process, fertilization becomes impossible, so workers frequently check the gauge to check the remaining amount.

(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 requires the user to manually hold the fertilizer container while the paste-like fertilizer is flowing into the fertilizer tank. The fertilizer has to be lifted continuously, which is extremely hard work, and the fertilizer leaks and is wasted.
Also, the leaked fertilizer got on his 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.

Furthermore, it is troublesome to frequently check the gauge visually during fertilization work, and even if there is a large amount left, it is necessary to replenish the fertilizer bag when passing a place where the fertilizer tank is kept, making full use of the capacity of the fertilizer tank. As a result, work efficiency decreased.

(d) Means for solving the problem The present invention provides a fertilizer bag container for storing a fertilizer bag containing paste fertilizer in an open state, and a discharge port provided at the bottom of the fertilizer bag container is provided below the fertilizer bag container. By communicating with a fertilizer tank that stores the paste fertilizer flowing from the fertilizer bag, and by connecting the fertilizer tank to a pump, the fertilizer bag containing the paste fertilizer can be easily put into the fertilizer bag container. This prevents waste of fertilizer and adhesion of fertilizer to clothes, and also allows the fertilizer in the fertilizer tank to be applied even if there is no paste fertilizer in the fertilizer bag container. Even if there is no fertilizer left in the fertilizer bag container, the fertilizer in the fertilizer tank can be applied, and fertilization work can be continued for a long time, expanding the range of options for fertilizer replenishment timing and improving work efficiency. The above-mentioned problems were solved.

(e) Action Put the paste fertilizer in the fertilizer bag into the fertilizer bag container, remove the lid of the fertilizer bag's outlet and fit it into the discharge port, move the machine forward and drive the pump, and the fertilizer bag container will be removed. The paste-like fertilizer inside the fertilizer bag flows into the fertilizer tank and accumulates.
A pump pressure-feeds the paste-like fertilizer in the fertilizer tank to the fertilization section for fertilization.

During fertilization work, when passing the place where the fertilizer bag is kept, the fertilization work can be continued even if the paste-like fertilizer in the fertilizer bag container is exhausted or has just disappeared. The paste fertilizer in the fertilizer tank is applied, and before the paste fertilizer in the fertilizer tank runs out, the empty fertilizer bag is removed from the fertilizer bag container, the fertilizer bag containing the paste fertilizer is placed in the fertilizer bag container, and the lid is removed. and flows into the fertilizer tank. Next, replace the other bag with an empty fertilizer bag, open it, and resume work.

Furthermore, if the amount remaining in the fertilizer tank is less than the amount required for one round trip of fertilization in a large field, even if paste-like fertilizer remains in the fertilizer tank, it can be replenished into the fertilizer bag container.

(F) Embodiment To explain an embodiment of the present invention about a riding fertilizing rice transplanter 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,
The planting device 7, which is attached with the fertilizer pipe 6 which becomes the fertilizer application section at the rear, is connected to the upper link 8 and the lower links 9, 9.
The pump 10 provided on the side of the vehicle body 1 is driven via a shaft 12 from a planting transmission case 11 and a transmission case 13.

On both sides of the driver's seat 14, suction hoses 1 are connected to the bottom outlet of the fertilizer bag container A to the fertilizer tank B (approximately the same size as a conventional fertilizer tank).
5, and the pump 1 is connected to the pump 1.
The suction port of No. 0 is connected to the fertilizer tank B by an introduction hose 16 having a distribution part, and the discharge port is connected to a pressure feeding hose 18 having an indicator 17 in the middle.
is connected to the fertilization pipe 6 by.

Further, the fertilizer bag container A has a flat bottom and an open upper part, and the opening edge is formed into an arcuate rib 19, and the housing C' of the extrusion device C has a flat top and a lower part. The opening edge is formed into an arcuate rib 20, one side of the housing C' is hinged to one side of the fertilizer bag container A so as to be openable and closable with a hinge 21, and the other side is hinged with a clamp 21a. It is attached removably.

Further, the extrusion device C supports movable bodies 24, 24 on a pair of left and right guide rails 22, 22 with guide rolls 23, . is support rod 2
5, 25 and the extrusion roller 2 via the bullets 26, 26.
7 is supported in pressure contact with the bottom plate of the fertilizer bag container A, and the pins 29, 29 provided at both ends of the support frame 28 of the extrusion roller 27 are connected to the pins 31, 31 provided in the intermediate portion of the bracket 30. wire 3
2 and 32 are fixed to the front part of the housing C' and support plate 3
A plurality of fixed pulleys 34 rotatably supported by a shaft 3...
. . . and a plurality of moving pulleys 35 . The bracket 30 is supported by two guide plates 38 having elongated holes in the front and back direction so that it does not move up and down but can move back and forth.
When the extrusion roller 27 is moved rearward, the rod 24a connecting the upper ends of the levers 24 engages the hook at the tip of the lever 39, and the coil springs 37...
Set the … to the stretched state.

Furthermore, the extrusion roller 27 is configured to have an elastic material such as rubber or synthetic resin attached or adhered to the outer periphery so as to press against the fertilizer bag 41 made of synthetic resin.

The fertilizer tank B is provided with a float 39a at the front to display the liquid level, and a filter 40 is attached to the end of the suction hose 15.

Since the paste fertilizer is contained in a fertilizer bag 41 made of synthetic resin, when feeding it, open the extrusion device C, put the fertilizer bag 41 into the fertilizer bag container A, and then insert the fertilizer bag 41 into the fertilizer bag container A. The discharge port is fitted to the upper end of the suction hose 15, and the bottom side is placed on the rib 19 at the rear of the fertilizer bag container A as shown in FIG. 2, with the extrusion roller 27 set at the rear. When the extrusion device C is closed and locked with the clamp 21a, the bottom of the fertilizer bag 41 is exposed to the upper and lower ribs 19,
20.

When the fertilizer tank B is empty in this state, the paste-like fertilizer in the fertilizer bag 41 flows into the fertilizer tank B, and the extrusion roller 27 is moved to the coil spring 37 via the fixed pulley 34 . . . , movable pulley 35 and wire 32. Because it is being pulled by ......, the extrusion roller 2
7 is guided by the guide rails 22, 22 and guide rolls 23 along with the movable body 24, and moves forward evenly from side to side, while the paste fertilizer is transferred to the fertilizer bag 4.
When the fertilizer bag 41 is empty, another bag is replaced and the extruder C is set.

Then, the paste-like fertilizer in the fertilizer tank B is sucked by the pump 10 and discharged toward the fertilization pipe 6 . In the same manner as described above, the paste-like fertilizer in the fertilizer tank B is pressurized because it is extruded into the fertilizer tank B.
This facilitates the suction action of the pump 10.

At that time, the extrusion roller 27 is operated by a plurality of fixed pulleys 34.
. . . is pulled by the coil spring 37 via the movable pulley 35 and the wires 32, 32 wrapped around them, so the expansion and contraction stroke of the coil spring 37 is small as shown in the upper and lower portions of FIG. Changes in the tension of the coil springs 37 can be kept to a minimum, and the extrusion roller 27, which moves widely from the rear end to the front end of the fertilizer bag container A, can be operated reliably over the entire stroke.

Furthermore, since a large number of coil springs 37 are used, the entire extrusion roller 27 can be moved strongly and with an average pressing force.

Furthermore, as the paste-like fertilizer in the fertilizer bag container A decreases, the movable bodies 24, 24 move forward, and when it reaches the front end, it indicates that the fertilizer bag 41 is empty. , 24 will display the content as a gauge, and from then on, the float 39a of fertilizer tank B allows you to know the remaining amount in fertilizer tank B, and when it is low, the aircraft will move along a ridge, etc. When you reach the place where the fertilizer bag 41 is placed, open the extrusion device C, take out the empty fertilizer bag 41, pull the extrusion roller 27 backward, set it with the lever 39, and place a new fertilizer bag 41.
After replacing one or two bags, close the extrusion device C and remove the lever 39 before restarting the work.

Since the paste fertilizer in the fertilizer 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, and there is no need to interrupt the fertilizer application process. If the area to be fertilized is small, it is possible to fertilize what is left in fertilizer tank B without replenishing it, and at the final stage of fertilizing one field, the amount of fertilizer required for the remaining unfertilized area is two bags. If only fertilizer bag container A is empty, replenish only one bag and continue fertilizing until the end.

Next, another embodiment will be explained with reference to FIG.
In this example, the extrusion forces of the left and right extrusion devices C and C are different. For example, the left extrusion device C has two coil springs 37, and the left and right coil springs 37 are the same as in the previous embodiment. If it is 6 pieces,
Fertilizer tanks B and B leading to each fertilizer bag container A and A are connected to the pump 10 by a common introduction hose 16, but the paste fertilizer in the fertilizer bag container A on the right side, which has a larger extrusion force, is extruded preferentially. As a result, the paste fertilizer in both fertilizer bag containers A and A and fertilizer tanks B and B do not run out one after another, and the paste fertilizer in fertilizer bag container A with the smaller pushing force continues to be applied. This makes it possible to replenish fertilizer at a convenient location while preventing the fertilizer from running out midway.

(G) Effects of the invention The invention provides a fertilizer bag container A that stores a fertilizer bag 41 containing paste-like fertilizer in an open state, and a discharge port provided at the bottom of the fertilizer bag container A is provided below the fertilizer bag container A. Since the fertilizer tank B is connected to the fertilizer tank B which stores the paste fertilizer flowing from the fertilizer bag 41, and the fertilizer tank B is connected to the pump 10, the paste fertilizer can be put into the fertilizer bag container A together with the bag. , it is possible to omit the conventional work of holding the fertilizer bag 41 in the hand and letting it flow into the fertilizer tank, and it is possible to improve the work efficiency without getting tired, and also to replenish the paste fertilizer. It is possible to reliably prevent it from being wasted due to leakage during work, or from adhering to work clothes.

Furthermore, the paste fertilizer in the fertilizer bag container A and the fertilizer tank B can be applied continuously, which further improves work efficiency and reduces the time for fertilizer replenishment until the fertilizer tank B is almost empty. This can be selected when the fertilizer bag container A is empty, or when only the fertilizer bag container A is empty, and a reasonable supply can be made according to the work process.
