[0020] The structure of the present utility model is described in detail below with reference to the accompanying drawings.

[0021] like Figures 1 to 4 As shown, an embodiment of the utility model provides a pesticide spraying device for vegetable planting, comprising a pesticide barrel 1 and a spray pipe 2. The front side of the pesticide barrel 1 is fixedly connected to the bottom of the spray pipe 2 through a hose, and the top of the spray pipe 2 is fixedly connected to a fixed shell 3. The inner cavity of the fixed shell 3 is movably connected to a replacement shell 4. The inner cavity of the replacement shell 4 is fixedly connected to a nozzle 5. The bottom of the nozzle 5 contacts the top of the spray pipe 2, and the inner cavity of the fixed shell 3 is provided with a fixing device 6.

[0022] refer to Figure 3 The fixing device 6 includes four movable fixed blocks 601, and a limiting hole 602 is opened on the surface of the movable fixed block 601. The surface of the movable fixed block 601 is fixedly connected to a spring 603, and the surface of the spring 603 is fixedly connected to the inner cavity of the fixed shell 3.

[0023] With the above solution, by providing the fixing device 6 , when the nozzle 5 and the replacement shell 4 are completely moved into the inner cavity of the fixed shell 3 , the fixing device 6 has a limiting effect on the positions of the nozzle 5 and the replacement shell 4 .

[0024] refer to Figure 3 The bottom of the inner cavity of the fixed shell 3 is fixedly connected with four limiting blocks 7 used in conjunction with the limiting holes 602, and the surface of the limiting blocks 7 is movably connected to the inner cavity of the limiting holes 602.

[0025] Adopting the above solution: by setting the limiting block 7, when the movable fixed block 601 moves, the limiting hole 602 will be driven to move along the surface of the limiting block 7. The cooperation between the limiting hole 602 and the limiting block 7 has a limiting effect on the moving position of the movable fixed block 601.

[0026] refer to Figure 3 The inner cavity of the fixed shell 3 is movably connected to a control rod turntable 8, and the side of the control rod turntable 8 away from the movable fixed block 601 penetrates the fixed shell 3 and extends to the outside of the inner cavity of the fixed shell 3.

[0027] The above solution is adopted: by providing the control lever turntable 8 , when the control lever turntable 8 rotates, the extrusion turntable 9 can be driven to rotate along the surface of the extrusion column 10 .

[0028] refer to Figure 4 The bottom of the control lever turntable 8 is fixedly connected to the extrusion turntable 9, and the top of the movable fixed block 601 is fixedly connected to the extrusion column 10 used in conjunction with the extrusion turntable 9, and the surface of the extrusion column 10 contacts the surface of the extrusion turntable 9.

[0029] The above solution is adopted: by setting the squeezing turntable 9 and the squeezing column 10, when the squeezing turntable 9 rotates, it can generate squeezing force on the squeezing column 10, and the squeezing column 10 subjected to the squeezing force can drive the movable fixed block 601 to move.

[0030] refer to Figure 2 The top of the fixed shell 3 is fixedly connected with a limiting ring 11 used in conjunction with the control rod turntable 8, and the surface of the limiting ring 11 is movably connected to the inner cavity of the control rod turntable 8.

[0031] The above solution is adopted: by setting the limit ring 11, rotating the control lever turntable 8, driving the control lever turntable 8 to rotate along the surface of the limit ring 11, and the setting of the limit ring 11 has a limiting effect on the rotation position of the control lever turntable 8.

[0032] refer to Figure 2 The surface of the replacement shell 4 is provided with a fixing groove 12 for use with the movable fixing block 601 , and the surface of the movable fixing block 601 contacts the inner cavity of the fixing groove 12 .

[0033] The above solution is adopted: by setting the fixed groove 12, when the replacement shell 4 and the nozzle 5 are moved to the inner cavity of the fixed shell 3, the control lever turntable 8 is released, and the restoring force generated by the spring 603 restoring its shape will drive the movable fixed block 601 to be stuck in the inner cavity of the fixed groove 12. The coordinated use of the movable fixed block 601 and the fixed groove 12 has a limiting effect on the position of the replacement shell 4 and the nozzle 5.

[0034] The working principle of this utility model:

[0035] During use, when the pesticide spraying equipment used for vegetable planting needs to conveniently replace the nozzle 5, the user first removes the nozzle 5 that needs to be replaced, and then rotates the control lever turntable 8 to drive the control lever turntable 8 to rotate along the surface of the limit ring 11. When the control lever turntable 8 rotates, it can drive the extrusion turntable 9 to rotate along the surface of the extrusion column 10. The extrusion force generated by the extrusion turntable 9 on the extrusion column 10 can drive the extrusion column 10 to move to the side away from the spray pipe 2. When the extrusion column 10 moves, it will drive the movable fixed block 601 to move to the side away from the spray pipe 2. When the movable fixed block 601 moves, it will drive the limiting hole 602 along the surface of the limiting block 7. Move, and at the same time, the force generated when the movable fixed block 601 moves causes the spring 603 to undergo elastic deformation. When the movable fixed block 601 is completely moved to the inner cavity of the fixed shell 3, the replacement shell 4 is moved to the inner cavity of the fixed shell 3, and the nozzle 5 is driven to move to the inner cavity of the fixed shell 3. When the bottom of the nozzle 5 is in close contact with the top of the spray pipe 2, the control lever turntable 8 is released, and the restoring force generated by the spring 603 restoring its shape will drive the movable fixed block 601 to be stuck in the inner cavity of the fixed groove 12. The coordinated use of the movable fixed block 601 and the fixed groove 12 has a limiting effect on the position of the replacement shell 4 and the nozzle 5. At this time, the pesticide spraying equipment used for vegetable planting can complete the convenient replacement of the nozzle 5.

[0036] To sum up: the pesticide spraying device for vegetable planting solves the problem that the pesticide spraying device used in the existing vegetable planting is a device for improving the spraying efficiency and coverage of pesticides by setting a fixing device 6, a movable fixing block 601, a limiting hole 602, a spring 603 and a fixing groove 12. In order to meet different vegetable spraying needs, the pesticide spraying equipment is provided with a variety of models of nozzles, which are usually installed by threaded connection. The thread position needs to be adjusted when replaced. The thread may be damaged due to long-term use or improper operation. The threaded connection may accumulate pesticide residues, making cleaning difficult. Once the thread has problems, professional tools need to be used to replace or repair it. This method of replacing the nozzle is not convenient enough, but the existing pesticide spraying equipment used for vegetable planting does not have a component for convenient replacement of the nozzle.
