DETAILED DESCRIPTION

[0018] like Figure 1 As shown, a device for spraying pesticides for crop diseases and insect pests comprises a connecting plate 1, wherein upper and lower ends of the connecting plate 1 are symmetrically provided with supporting plates 2, a spraying operation area is formed between the two sides of the connecting plate 1 and the symmetrical supporting plates 2, and a pressure tank 3 is also included, wherein the pressure tank 3 is arranged between the symmetrical supporting plates 2, an air cylinder 4 is arranged on the upper supporting plate 2, a telescopic end of the air cylinder 4 penetrates through the supporting plate 2 and is slidably arranged in the pressure tank 3, a push plate 5 is arranged at the telescopic end of the air cylinder 4, an outer side wall of the pressure tank 3 away from the connecting plate 1 is connected with a liquid spray pipe 6, a rubber valve 7 is arranged in a port at one end of the liquid spray pipe 6 away from the pressure tank 3, a liquid inlet assembly 8 is connected to the bottom of the lower supporting plate 2, the liquid inlet assembly 8 is communicated with the pressure tank 3, the telescopic end of the air cylinder 4 pushes the push plate 5, so that the internal pressure of the push plate 5 is converted, and the liquid medicine is sprayed out through the liquid spray pipe 6 in a positive pressure state, and the liquid medicine is replenished into the pressure tank 3 through the liquid inlet assembly 8 in a negative pressure state.

[0019] like Figure 3-5 As shown, in order to pressurize the liquid sprayed from the spray pipe 6 and realize the negative pressure state in the pressure tank 3 at the same time, and avoid the injection of air into the spray pipe 6 when the liquid is added to the pressure tank 3, the spray pipes 6 are symmetrically distributed and arranged at equal intervals. A one-way spray assembly 9 is provided in the spray pipe 6. The one-way spray assembly 9 includes a retaining ring 10, a connecting rod 11, a plug 12 and a vertical plate 13. The retaining ring 10 is arranged in the middle of the inner wall of the spray pipe 6. The retaining ring 10 is arranged in an annular shape. The connecting rod 11 penetrates the retaining ring 10 and the rubber valve 7 and is slidably arranged in the spray pipe 6. The plug 12 is arranged at one end of the connecting rod 11 close to the rubber valve 7, and the vertical plate 13 is arranged at the end of the connecting rod 11. At the other end, a support spring 14 is wound around the outer wall of the connecting rod 11, and the support spring 14 is located between the retaining ring 10 and the vertical plate 13. The telescopic end of the cylinder 4 drives the push plate 5 to press down, so that the pressure below the pressure tank 3 increases, and the liquid medicine enters the spray pipe 6, and is pressurized when passing through the rubber valve 7, pushing the plug 12 to move, and spraying out through the gap between the plug 12 and the rubber valve 7. At the same time, the connecting rod 11 drives the vertical plate 13 to move when the plug 12 is displaced, and the support spring 14 provides a reverse supporting force to the plug 12 to increase the pressure of the sprayed liquid. In the initial state, the plug 12 is in contact with the end of the spray pipe 6, and the end of the spray pipe 6 is in a closed state.

[0020] like Figure 4As shown, in order to realize the spraying of water column in the pressure tank 3 in a positive pressure state and the filling of liquid in the pressure tank 3 in a negative pressure state, the liquid inlet assembly 8 includes a one-way valve 15, a connecting pipe 16, a diverter box 17 and a liquid inlet pipe 18. The one-way valve 15 passes through the lower bearing plate 2 and is connected to the bottom of the pressure tank 3. One end of the connecting pipe 16 is connected to the one-way valve 15, and the diverter box 17 is connected to the other end of the connecting pipe 16. The liquid inlet pipe 18 is connected to the bottom of the diverter box 17. When the telescopic end of the cylinder 4 drives the push plate 5 to contract, the pressure tank 3 is in a negative pressure state, and the external medicine liquid is drawn through the liquid inlet pipe 18, enters the diverter box 17, and enters the one-way valve 15 through the symmetrical connecting pipe 16. The one-way valve 15 is opened, and the medicine liquid enters the pressure tank 3 to realize the replenishment of the medicine liquid. At the same time, the non-return effect of the one-way valve 15 is utilized to prevent the medicine liquid from flowing out from the bottom of the pressure tank 3 when the telescopic end of the cylinder 4 is extended.

[0021] like Figure 1 , Figure 2 and Figure 4 As shown, the horizontal direction of the upper and lower symmetrical supporting plate 2 is connected with a support rod 19, and the horizontal outer wall of the supporting rod 19 is slidably provided with a baffle 20. The upper part of the baffle 20 is connected with a positioning bolt 21, and the end face of the positioning bolt 21 is in contact with the outer wall of the supporting rod 19. The supporting rod 19 is used to support the supporting plate 2 so that the baffle 20 slides in the horizontal direction of the supporting rod 19, and the distance between the baffle 20 and the spray pipe is adjusted to change the impact position of the sprayed liquid, so as to realize the spraying state and spraying range of the liquid.

[0022] Among them, the side walls of the symmetrical supporting plates 2 adjacent to the supporting rods 19 are connected with fixing plates 22, which are symmetrically arranged up and down. A fixing hole 23 is provided on the side of the fixing plate 22 away from the supporting plate 2, and the fixing hole 23 in the fixing plate 22 is used to connect the fixing device to realize the installation of the device.

[0023] When in use, the operator installs the device on the mobile carrier through the fixing hole 23, and connects the liquid inlet pipe 18 at the bottom of the liquid inlet assembly 8 to the external container. In the initial state, the push plate 5 at the telescopic end of the cylinder 4 is at the bottom of the pressure tank 3. Before spraying, the cylinder 4 is driven to contract, and the push plate 5 rises. The pressure tank 3 is in a negative pressure state, and the liquid medicine in the container is extracted through the connecting pipe 16. The liquid medicine enters the diverter box 17 and flows to the one-way valves 15 on both sides through the connecting pipe 16, which lifts the one-way valve 15. At the same time, the one-way spray assembly 9 closes the port of the spray pipe to achieve the replenishment of liquid medicine in the pressure tank 3.

[0024] When spraying the liquid medicine, the cylinder 4 pushes the push plate 5 downward, the pressure tank 3 is in a positive pressure state, the liquid medicine enters the liquid spraying pipe 6, and is pressurized when passing through the rubber valve 7, pushing the plug 12 to move, and spraying out through the gap between the plug 12 and the rubber valve 7. At the same time, the connecting rod 11 drives the vertical plate 13 to move when the plug 12 moves, and the support spring 14 provides a reverse support force to the plug 12 to realize pressurization of the sprayed liquid. In the initial state, the plug 12 contacts the end of the liquid spraying pipe 6, and the end of the liquid spraying pipe 6 is in a closed state;

[0025] In order to adjust the spraying surface, the baffle 20 is adjusted to move in the horizontal direction of the support rod 19, so that the liquid sprayed from the spray pipe impacts the side wall of the baffle 20, and the liquid is dispersed within the spraying operation area. The distance between the baffle 20 and the spray pipe is used to adjust the spraying surface of the liquid to achieve spraying of the liquid.
