Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a liquid supply device for loading a spraying liquid onto a liquid spraying vehicle.

[Conventional technology]

Conventionally, to load liquid from tanks installed in fields or on the banks of the field onto a liquid spraying vehicle, workers either pumped the liquid out of the tank using a container and supplied it to the spraying vehicle tank, or used a pump with an engine. However, the following inconveniences occurred.

[Problem that the invention attempts to solve]

In other words, in the case of manual supply, it was not only time-consuming to pump out the liquid from the tank and transport the pumped liquid, but also required a great deal of labor.If a pump with an engine was used, it was expensive due to the engine. It was economically disadvantageous to have to prepare a supply device for this purpose.

SUMMARY OF THE INVENTION An object of the present invention is to provide a supply device that allows liquid to be loaded into a spray vehicle easily and quickly, and which is economically advantageous.

[Means for solving problems]

The liquid supply device for a liquid spraying vehicle according to the present invention is characterized by: a jet pump; a first hose that connects the jet flow generating nozzle of the jet pump to a discharge port of an engine-driven spraying pump equipped on the liquid spraying vehicle; and a second hose that connects the discharge port of the jet pump to the liquid tank installed on the liquid spraying vehicle, and its functions and effects are as follows.

[Effect]

Connect the first hose to the discharge port of the spray pump,
By driving the spray pump, the jet pump is supplied with liquid from the spray pump, and this supplied liquid sucks the liquid in the tank and supplies it to the spray vehicle tank.

[Effect of idea]

The pump configuration allows liquid to be easily and quickly loaded into the spray vehicle, making work easier and more efficient.

Furthermore, unlike when using a pump with an engine, there is no need to prepare a dedicated engine for loading, but the engine originally equipped in the sprayer can be used, making it possible to easily and quickly load liquid, which is economically advantageous. Ta. Furthermore, when the spraying pump is used as a pump that loads liquid only by this means, the discharge side flow path of the pump can be connected to the spray nozzle and the spray wheel tank, and the suction side flow path of the pump can be switched. Instead of switching between two systems, connecting and switching the sprayer to the spray vehicle tank and the tank outside the sprayer, you can switch only one system, connecting and switching the spray pump's discharge port to the spray nozzle and jet pump. From this point of view as well, liquid loading has become advantageous in terms of operation.

〔Example〕

As shown in FIGS. 1 and 2, a liquid tank 4a is installed on each of the left and right sides of the engine 2 of the self-propelled aircraft, which has traveling wheels 1, an engine 2 that drives the wheels 1, a control handle 3, etc. or 4b, and a liquid spray pump 5 is connected to the engine 2 via a transmission device 6 and a traveling transmission case 7 at the rear of the self-propelled aircraft, and via a hose 8. It is mounted in a state connected to the pair of liquid tanks 4a and 4b so as to take out the liquid, and a plurality of spray nozzles 9 are arranged in parallel in the lateral direction of the aircraft. A pair of free-rotating ground wheels 10a, 10
A spreading device having each of b is mounted on the rear of the self-propelled aircraft in a rolling manner around the axis P so that the height above the ground of the left and right spray nozzles 9 is the same regardless of the left and right inclination of the self-propelled aircraft. can be connected, and
Each of the nozzles 9 is connected to the pump 5 through a hose 11 so as to be supplied with liquid, thereby configuring a walking liquid spray vehicle that sprays liquids such as weeding liquid, insect repellent liquid, liquid fertilizer, etc. .

As shown in FIG. 3, there is a jet pump 12, a second hose 16 extending from the discharge port 13 of the pump 12, and a first hose extending from the liquid supply side of the jet flow creating nozzle 15 equipped on the jet pump 12. 14 constitute a liquid supply device that supplies and loads the internal liquid of the spray vehicle external tank 17 into the spray vehicle tanks 4a and 4b using the spray pump 5.

That is, as shown in FIG. 3, the first hose 14 is connected to the discharge port 5a of the spray pump 5 instead of the hose 11, and the second hose 16 is connected to the tank 4a or 4b, and The jet pump 12 is put into the tank 17 outside the spray vehicle.
Then, the spray pump 5 is driven to supply the liquid remaining in the spray vehicle tanks 4a and 4b to the nozzle 15 for injection, and using this injection force, the internal liquid of the tank 17 is released from the suction port with the strainer 18. This suction liquid is supplied together with the liquid ejected from the nozzle 15 from the discharge port 13 via the second hose 16 to the sprayer tank 4a or 4b.
