Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid feed recovery device,
It is used for collecting chemicals, water and the like remaining in a liquid sending hose (liquid sending pipe) after performing these operations in an orchard or the like and spraying and spraying a chemical.

[0002]

2. Description of the Related Art Conventionally, in orchards and the like, chemicals and water have been supplied through a liquid feed hose (liquid feed pipe) by the operation of a pump to spray or water the fruit trees.

[0003]

However, in such a conventional pump, the operation of the pump is stopped to terminate the application of the chemical solution, watering, and the like. Chemical liquid and water remain in the liquid hose (liquid supply pipe), and as a result, there is an inconvenience that the chemical liquid and water remaining at the time of cleaning up spill out and contaminate the surroundings, and that the chemical liquid and water are wasted. did.

[0004] It is an object of the present invention to eliminate the above disadvantages.

[0005]

According to another aspect of the present invention, there is provided a liquid-feeding and recovering apparatus comprising a pump, a first three-way valve, a second three-way valve, a first auxiliary pipe member, and a second auxiliary pipe member. The first three-way valve and the second three-way valve each have a first connection port, a second connection port, and a third connection port, and these three-way valves are selectively operated by the first connection port and the third connection port. The first connection port of the first three-way valve can be connected to the two connection ports or the first connection port and the third connection port, and can be connected to the liquid suction port of the pump. The first connection port of the second three-way valve is connected to the liquid feed port of the pump, and the second connection port of the first three-way valve and the second connection port of the second three-way valve are connected to the first auxiliary pipe member. The third connection port of the first three-way valve and the third connection port of the second three-way valve are connected by a second auxiliary pipe member. Under the connecting liquid-absorbing pipe member in the middle of the first auxiliary tube, due to connecting the liquid supply tube member to the second auxiliary pipe,

The first three-way valve is operated to communicate the first connection port and the second connection port, and the second three-way valve is operated to communicate the first connection port and the third connection port. If the pump is operated in a state where the pump is operated, the pump sucks a chemical solution, water, etc. from the storage tank via the first auxiliary pipe from the water absorption pipe member, and the liquid feed pipe member via the second auxiliary pipe. The liquid can be sent to an appropriate location. On the other hand, the first three-way valve was operated to communicate the first connection port and the third connection port, and the second three-way valve was operated to communicate the first connection port and the second connection port. If the pump is operated in the state, the pump sucks the chemical solution, water, and the like remaining in the liquid sending pipe member through the second auxiliary pipe, and the pump sucks the liquid through the first auxiliary pipe. It can be sent to a storage tank.
