Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a rice transplanter, a transplanting machine. This invention relates to a fertilization device that applies fertilizer simultaneously with the planting or sowing of seedlings in a flooded direct sowing machine, etc., and particularly to a fertilization device for agricultural vehicles that has an improved arrangement of the fertilizer passage and the fertilization pump. [Conventional technology] Conventionally, rice transplanters and transplanting machines. In agricultural vehicles such as hot water direct sowing machines, a fertilizer tank that mainly stores paste or liquid fertilizer is installed on both sides of the front of the vehicle, and the fertilizer discharged from this fertilizer tank is supplied to a fertilizer pump via a fertilizer flow path. Fertilizers that pressurize the fertilizer and feed it to a fertilization nozzle to apply it to the field are disclosed in, for example, Japanese Patent Laid-Open No. 61-271912, Japanese Patent Laid-Open No. 1-181717, and Japanese Utility Model Laid-open No. 63-1.
This is known from Publication No. 0832. In the prior art described above, the fertilization pumps were placed on the left and right sides of the fertilizer flow path. [Problem to be solved by the invention] In the above-mentioned fertilizer application device, after the work is completed, the remaining fertilizer in the fertilizer tank or fertilizer application tank is discharged through the drain hose, and the fertilizer is removed from the fertilizer tank or the fertilizer application tank. We are trying to prevent the fertilizer from solidifying in the fertilizer tank, but the fertilizer pump is on the left and right of the fertilizer flow path! If the fertilizer pump was installed in a large area, the fertilizer could not be completely discharged from the fertilizer pump, and the remaining fertilizer would harden into crystal grains, which could cause blockages. In order to solve the above-mentioned problems, the present invention provides a fertilization pump and a fertilizer flow path. The purpose of this invention is to provide a fertilizer application device for agricultural vehicles that has an improved arrangement of suction hoses, fertilizer discharge pipes, etc. [Means for Solving the Problem] In order to achieve the above object, the present invention includes a fertilizer tank,
In an agricultural vehicle equipped with a fertilization device consisting of a fertilization pump that is supplied with fertilizer discharged from the fertilizer tank via a fertilizer flow path, pressurizes the fertilizer, and sends it to a fertilization nozzle, the sub-tank of the fertilization pump is provided with: Arrange the above fertilizer channel so that it is above the sub-tank. The fertilizer flow path is arranged in a lateral direction perpendicular to the traveling direction of the vehicle body, and a suction hose is connected to the inside of the vehicle body, and a fertilizer discharge pipe is connected to the outside of the vehicle body. ．． [Function] Due to the above-mentioned oval configuration, fertilizer will be supplied from below to the sub-tank of the fertilization pump, and after the work is completed, the fertilizer in the sub-tank will accumulate at the bottom of the sub-tank due to its own weight.
The drain hose allows the fertilizer to be drained smoothly and prevents fertilizer from remaining in the fertilizer pop. [Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

Suction hose 24 is placed inside the car body, and drain hose 32 is placed outside the car body! Therefore, the fertilizer in the fertilizer tank 13 and the increase tank 14 is supplied from the suction hose 24 to the fertilization pump via the sub-tank. 1 [! ! When the fertilizer reaches the pump hose 36, remove the air bleed hose 40 from the joint 41 and bleed the air, filling the sub-tank with fertilizer.Connect the air bleed hose 40 to the joint 41 and transfer the fertilizer from the sub-tank to the fertilizer pump. 26, the fertilizer is applied to the field from the fertilization nozzle 28 via the control section 27. After the work is completed, drain hoses 18, 20.
32, but in the sub-tank, the air bleed hose 40 removed from the joint 41
, connect the water hose to the return pipe 42, and connect the sub tank 31.
．． 31a, the control unit 27, the fertilizer application nozzle 27, etc., and completely discharge the fertilizer. Further, when the control unit 27 is switched during the fertilization operation, the fertilizer is returned to the sub tank through the return pipe 42 and empty air release hose 40. [Effects of the Invention] As explained above, according to the fertilizer application device for the agricultural vehicle of the present invention, the fertilizer flow path is arranged and communicated with the sub-tank of the fertilizer pump so that the sub-tank is in the upper position. , is installed laterally perpendicular to the direction of travel of the car body, and a suction hose is connected to the inside of the car body, and a fertilizer discharge pipe is connected to the outside of the car body, so that the crystal grains of the paste fertilizer and other substances contained in the fertilizer can be removed. Fertilizer settles and precipitates in the hose at the bottom of the pipe, but because the fertilizer is constantly flowing through the hose, the precipitation of crystal grains and other impurities does not progress and cause blockages. Furthermore, when the fertilizer is discharged through the fertilizer discharge pipe after work is completed, the fertilizer is discharged straight and does not remain in the sub-tank of the fertilizer pump. Furthermore, the fertilizer discharge pipe is located on the outside of the vehicle, making it easy to discharge fertilizer.
