[0034] As Figures 1-4As shown, a pesticide spraying device for agricultural planting includes a pesticide tank 1 for containing pesticide liquid, a liquid pumping pump 2 for pumping the pesticide liquid from the pesticide tank 1, the middle part of the pesticide tank 1 is provided with a connecting pipe 101 which is in communication with the inside of the pesticide tank 1, and further includes: a liquid outlet pipe 3 which is in communication with the lower part of the pesticide tank 1 at one end and the other end of which is higher than the liquid level in the pesticide tank 1; a liquid pumping pipe 4 which is in communication with the water pumping end of the liquid pumping pump 2 at one end and is in plug-in communication with the other end of the liquid outlet pipe 3 at the other end; a three-way pipe 5 which is in communication with the water outlet end of the liquid pumping pump 2; a return pipe 6 which is in communication with one port of the three-way pipe 5 at one end and is in communication with the connecting pipe 101 at the other end; a pressure maintaining valve 7 which is arranged on the return pipe 6, the outlet of the pressure maintaining valve 7 is in communication with the connecting pipe 101 through the return pipe 6, and the inlet of the pressure maintaining valve 7 is in communication with one port of the three-way pipe 5 through the return pipe 6; a pesticide spraying pipe 8 which is provided with a pesticide spraying head 801 and a valve 802, the pesticide inlet end of the pesticide spraying pipe 8 is in communication with one port of the three-way pipe 5, and the pressure maintaining valve 7 is opened when the valve 802 is closed.

[0035] In use, the lower end of the liquid outlet pipe 3 is in communication with the lower part of the pesticide tank 1, and the upper end is located at the upper part outside the pesticide tank 1 and can be fixed by buckling or binding wire, etc., the upper end of the liquid outlet pipe 3 is higher than the highest liquid level in the pesticide tank 1 when liquid exists in the pesticide tank 1, so that the liquid is prevented from flowing out, and the valve 802 does not need to be controlled, so that the use is simple. When the pesticide is prepared before spraying, the pesticide in a small bottle can be poured into the pesticide tank 1 from the upper part, then the liquid pumping pipe 4 and the upper end of the liquid outlet pipe 3 are disconnected, the end of the liquid pumping pipe 4 is put into an external water tank, the liquid pumping pump 2 is opened, and the valve 802 of the pesticide spraying pipe 8 is kept closed, so that water can be pumped from the external water tank, the water outlet end of the liquid pumping pump 2 opens the pressure maintaining valve 7 under high pressure, water enters the pesticide tank 1 through the return pipe 6, and the water and the pesticide are mixed and diluted by water flow impact, after sufficient water is pumped, the liquid pumping pump 2 is closed, and a scale line, etc. can be arranged on the pesticide tank 1.

[0036] After the liquid in the pesticide tank 1 is mixed, the liquid pumping pipe 4 and the upper end of the liquid outlet pipe 3 are in plug-in communication, the pesticide spraying pipe 8 is held by hand, the valve 802 is opened, the liquid pumping pump 2 is opened, the liquid pumping pump 2 pumps the pesticide liquid from the lower part of the pesticide tank 1 through the liquid pumping pipe 4 and the liquid outlet pipe 3, when the valve 802 is opened, the pesticide spraying pipe 8 sprays the pesticide from the pesticide spraying head 801 to release pressure, the pressure at the pressure maintaining valve 7 is small, and the pressure maintaining valve 7 is kept closed. The pesticide spraying pipe 8 is a long straight pipe, and can be in communication with one port of the three-way pipe 5 through a long hose. The three ports of the three-way pipe 5 are in communication with the return pipe 6, the pesticide spraying pipe 8 and the water outlet end of the liquid pumping pump 2, respectively.

[0037] The pesticide tank 1 and the liquid pumping pump 2, etc. can be installed on a small car which walks, so that the small car is convenient to move. During the pesticide spraying process, the valve 802 of the pesticide spraying pipe 8 is closed, the pressure maintaining valve 7 is opened, the liquid in the pesticide tank 1 circulates and flows, and precipitation is avoided.

[0038] The upper end of the liquid outlet pipe 3 is located at a high position, so that the length of the liquid pumping pipe 4 is also relatively long, and the liquid pumping pipe 4 is convenient to extend into an external water tank to pump water.

[0039] Further, the connecting pipe 101 is arranged obliquely, and an axis direction of the connecting pipe 101 points to the bottom of the medicine box 1.

[0040] In use, the connecting pipe 101 obliquely pointing to the bottom of the medicine box 1 can better drive the liquid in the medicine box 1 to flow when the liquid pump 2 pumps liquid into the medicine box 1, so as to improve the flowability and reduce precipitation or avoid uneven mixing. Compared with the connecting pipe 101 being above the liquid level or being at a high position, the connecting pipe 101 being at the middle position can better drive the overall liquid in the medicine box 1 to flow, and the impact force on the bottom of the medicine box 1 is better. Generally, the height of the medicine box 1 matches the amount of liquid, and the middle position of the medicine box 1 is also the middle position of the liquid at the beginning.

[0041] Further, the other end of the liquid pumping pipe 4 is connected and communicated with the other end of the liquid outlet pipe 3 through the quick plug assembly 9.

[0042] In use, the quick plug assembly 9 is an existing quick plug communication piece, which is convenient to plug and pull and has good sealing performance. A relatively heavy quick plug assembly 9 can be selected, so that when the liquid pumping pipe 4 and the liquid outlet pipe 3 are disconnected, the weight of the quick plug assembly 9 facilitates the extension of the end of the liquid pumping pipe 4 into the external water tank to pump water.

[0043] Further, the lower part of the medicine box 1 is semispherical, and one end of the liquid outlet pipe 3 is communicated with the middle part of the bottom end of the medicine box 1.

[0044] In use, the lower part of the medicine box 1 is semispherical, that is, the middle part of the bottom end of the lower part is the lowest position in the medicine box 1, so that the liquid outlet pipe 3 is communicated with the lowest position to reduce the liquid residue. At the same time, the impact on the bottom by the connecting pipe 101 can better reduce the precipitation effect.

[0045] Further, it further comprises a filter cartridge 10, the side wall has filter holes, and the filter cartridge 10 is arranged at the middle part of the bottom end of the medicine box 1 and covers the position where the liquid outlet pipe 3 is communicated with the medicine box 1.

[0046] In use, the filter cartridge 10 covers the end of the liquid outlet pipe 3, and can play a filtering protection role on the liquid pump 2.

[0047] Further, it further comprises a stirring shaft 11 rotatably arranged in the medicine box 1, and the side surface of the stirring shaft 11 has a plurality of stirring rods 1101; and a mounting shaft 12 coaxially arranged at the lower end of the stirring shaft 11, and the mounting shaft 12 extends into the inside of the filter cartridge 10 after penetrating through the upper end of the filter cartridge 10, and the side surface of the mounting shaft 12 has a plurality of brushes 1201, and the end of the brush 1201 abuts against the inner wall of the filter cartridge 10.

[0048] In use, when the pesticide is mixed with water for dilution, stirring can be performed by an external stirring rod or the like, and the stirring rod 1101 can also be rotated by the stirring shaft 11, and the stirring shaft 11 can be rotated by a motor or manually driven. The mounting shaft 12 extends into the filter cartridge 10 and drives the brush 1201 to rotate, thereby cleaning the filter holes in the filter cartridge 10 to prevent impurities from entering the filter cartridge 10 and prevent the filter cartridge 10 from being blocked.

[0049] Further, the utility model also comprises a scraping bottom plate 13, which is arc-shaped and matched with the lower semispherical inner wall of the pesticide box 1. The scraping bottom plate 13 is arranged at the lower part of the stirring shaft 11 and rotates outside the filter cartridge 10.

[0050] In use, the scraping bottom plate 13 is arc-shaped and close to the bottom wall of the pesticide box 1. The stirring reduces the deposition at the bottom and improves the flowability.
