Description

[Detailed Description of the Invention] (a) Field of Industrial Application The present invention relates to a fertilizer applicator that pumps liquid fertilizer to apply fertilizer.

(B) Conventional technology Conventionally, the upper part of a pair of left and right fertilizer tanks is connected by a supply pipe having an inlet, the lower part is connected by a discharge pipe, and the discharge pipe is connected to a pump via a suction hose. A fertilizer applicator that applies fertilizer discharged by a nozzle with a nozzle is already known.

(C) Problems to be solved by the invention In the known fertilizer applicator, when liquid fertilizer is injected into the replenishment port of the replenishment pipe, it slowly flows in the left and right substantially horizontal replenishment pipes and flows into the left and right fertilizer tanks. Therefore, if it is not gradually injected, it may overflow from the replenishment port, and it will flow out from the discharge pipe after it has accumulated in the fertilizer tanks on the left and right, which slows down the supply of fertilizer to the pump. Further, when the machine body swings to the left or right during the injection, there is a problem that an air trapping phenomenon occurs and an air bleeding operation must be performed.

(D) Means for solving the problems The present invention is to connect the left and right fertilizer tanks to the upper part with a supply pipe having an injection part and the lower part with a discharge pipe, and connect the discharge pipe to a pump. The fertilizer sent is discharged from the nozzle to apply fertilizer, and by connecting the replenishment pipe and the discharge pipe with a bypass pipe, the liquid fertilizer injected from the replenishment port can be simply flowed into the fertilizer tank from the left and right replenishment pipes. Instead, the above-mentioned problems were solved by directly flowing into the discharge pipe from the bypass pipe.

(E) Action When liquid fertilizer is poured into the supply port of the supply pipe,
It flows through the left and right supply pipes into the left and right fertilizer tanks, and at the same time directly flows into the discharge pipe from the bypass pipe.

Therefore, the fertilizer can be quickly supplied from the discharge pipe to the pump, and even if the machine body swings to the left or right during the fertilizer injection, air is not bitten.

(F) Embodiment An embodiment of the present invention will be described with reference to the riding fertilizer paddy planting machine shown in the drawings. The engine 2 and the mission case 3 are mounted on the front part of the machine body 1, and the planting device 4 is mounted on the rear part via the link 5. The engine 2 is decelerated by the transmission case 3 and distributed to the front wheels 6, the rear wheels 7 and the planting device 4.

Also, fertilizer tanks 8, 8 are installed on both sides of the front of the aircraft,
A supply pipe 11 with a supply port 10 in the middle
, And the lower part is connected by an exhaust pipe 12.
A fertilizer pump 15 having a sub-tank 13 and composed of a plurality of screw pumps is attached to a side surface of the midway portion of the machine body 1, and the sub-tank 13 and an intermediate portion of the discharge pipe 12 are connected by a suction hose 16. Each discharge port of the plurality of screw pumps is connected to a nozzle 20 attached to the float of the planting device 4 by a hose 18 having an indicator and a switching valve 17 in the middle.

The lower portion of the supply port 10 of the supply pipe 11 and the intermediate portion of the discharge pipe 12 are connected by a bypass pipe 21 as shown in FIGS. Reference numeral 23 is an air breather attached to the top plate of the fertilizer tank 8.

In the above-mentioned device, when replenishing liquid fertilizer, for example, paste fertilizer, when the lid 22 is opened and the fertilizer bag or the container for pouring is poured, the fertilizer directly flows into the discharge pipe 12 from the bypass pipe 21 and is left. Left and right supply pipes 1
The fertilizer in the discharge pipe 12 flows into the sub tank 13 via the suction hose 16 via the suction hoses 16 and 1 and 11 from the left and right fertilizer tanks 8 and 8.

Even if the machine swings to the left or right during such fertilizer replenishment work, the fertilizer directly flows into the discharge pipe 12 through the bypass pipe 21, so air is rarely mixed in, and the fertilizer is paste-like fertilizer. Even if it has high viscosity and poor fluidity, it will flow into the sub tank without delay.

The fertilizer pump 15 is driven by the engine 2 via the transmission 25, sucks the fertilizer in the sub tank 13 and discharges it to the hose 18, and the fertilizer pump 15 applies the fertilizer to the soil from the nozzle 20.

4 and 5 show another embodiment,
Fertilizer tanks 8 with fertilizer pumps 15 on both sides of the front of the machine
Is arranged between the lower part of the supply port 10 of the supply pipe 11, the upper part of the sub-tank 13 is connected by a bypass pipe 21, when the paste fertilizer is injected from the supply port 10,
It is distributed to the left and right supply pipes 11, 11 and the bypass pipe 21 immediately below the supply port 10, and what has flown into the bypass pipe 21 will directly flow into the sub-tank 13. In addition to having the same effect as the example, the suction pipe 16 different from the hose 18 can be omitted by simply lengthening the hose 18.

FIG. 6 shows another example of the liquid fertilizer, in which the constituent elements of the paste-like fertilizer are powders, the powders are put in the fertilizer tank 8, water is injected, and the mixture is stirred as necessary. This is a paste fertilizer, and according to this example, it is easy to carry the fertilizer and put it in the tank, and the work clothes and hands are not soiled.

(G) Effect of the Invention As described above, the present invention connects the left and right fertilizer tanks 8 and 8 with the replenishment pipe 11 having the injection part and the lower part with the discharge pipe 12, and connects the discharge pipe 12 to the pump 15. Then, the fertilizer sent from the pump 15 is discharged from the nozzle 20 so as to be fertilized, and the supply pipe 11 and the discharge pipe 12 are connected by the bypass pipe 21, so when the fertilizer is injected into the supply port 10, A part of it is directly discharged from the bypass pipe 21
It flows into 12, and the other part is distributed to the left and right fertilizer tanks 8 by the supply pipe 11, whereby it is possible to prevent the fertilizer from overflowing from the supply port 10 at the time of supply,
Further, the fertilizer can be directly supplied to the discharge pipe and can be quickly supplied to the pump. Furthermore, even if the aircraft swings to the left or right while replenishing fertilizer, the bypass pipe 21
Since the fertilizer flowing into 12 also flows into the fertilizer tank, air can be prevented from being mixed.
