[0024] Example 1

[0025] Please refer to Figures 1-4 A pesticide sprayer for vegetable cultivation includes a traveling vehicle 1, a pesticide supply mechanism mounted on the traveling vehicle 1, a support frame 2 mounted on the traveling vehicle 1, and a covering spraying mechanism mounted on the support frame 2. The covering spraying mechanism includes a boom 3, a U-shaped opening cover 4 fixedly mounted on the boom 3, a U-shaped spraying pipe 5 built into the U-shaped opening cover 4, and a plurality of atomizing nozzles 6 evenly distributed on the U-shaped spraying pipe 5. The bottom of the U-shaped opening cover 4 is provided with a collection groove 7 for collecting pesticide liquid. The output end of the pesticide supply mechanism is connected to the input end of the U-shaped spraying pipe 5.

[0026] For details, please refer to Figure 4The bottom of the U-shaped opening cover 4 is provided with a discharge valve 16 that communicates with the inside of the collection tank 7.

[0027] For details, please refer to Figure 1 The drug supply mechanism includes a cartridge 18 and a pressure pump 19. The input end of the pressure pump 19 extends into the cartridge 18, and the output end of the pressure pump 19 is connected to the middle input end of the U-shaped liquid supply pipe 9. Furthermore, it also includes a flexible connecting pipe, one end of which is connected to the input end of the pressure pump 19, and the other end of which is connected to the middle input end of the U-shaped liquid supply pipe 9.

[0028] For details, please refer to Figure 4 It also includes two Venturi tubes 8 and a U-shaped liquid supply tube 9. The output ends of the two Venturi tubes 8 are respectively connected to the two bottom input ends of the U-shaped spray tube 5, and the two output ends of the U-shaped liquid supply tube 9 are respectively connected to the input ends of the two Venturi tubes 8. The middle throat of each of the two Venturi tubes 8 is provided with a suction tube 10 that extends into the collection tank 7; furthermore, the output end of the drug supply mechanism is connected to the middle of the U-shaped liquid supply tube 9.

[0029] For details, please refer to Figure 4 The inlet end of the suction tube 10 is equipped with a filter cover 17.

[0030] The pesticide sprayer for vegetable cultivation provided in this embodiment can discharge the pesticide solution recovered in the collection tank 7 by opening the discharge valve 16; the pressurized liquid in the cartridge 18 is injected into the U-shaped supply pipe 9 after being pressurized by the pressurized liquid pump 19; the pressurized liquid at the output end of the U-shaped supply pipe 9 enters the two Venturi tubes 8; the pressure at the suction pipe 10 of the Venturi tube 8 decreases; the liquid in the collection tank 7 is sucked into the Venturi tube 8 through the suction pipe 10; then the pressurized liquid enters the U-shaped supply pipe 9 simultaneously from both ends, so that the liquid is evenly sprayed out after passing through the atomizing nozzle 6. This can improve the uniformity of the liquid sprayed from the atomizing nozzle 6, and can directly recycle the liquid recovered in the collection tank 7; while the filter cover 17 can prevent debris in the collection tank 7 from entering the suction pipe 10, avoiding blockage of the suction pipe 10 or the subsequent atomizing nozzle 6.

[0031] Example 2

[0032] The vegetable sprayer provided in Example 1 has been further optimized. For details, please refer to [link / reference]. Figure 3 A slide block 11 is slidably mounted on the support frame 2, and the boom 3 is fixedly mounted on the slide block 11. A lifting drive component 12 is mounted on the support frame 2 to provide power for the slide block 11 to slide up and down. Furthermore, the lifting drive component 12 is preferably a threaded screw and a motor. The threaded screw is rotatably mounted on the support frame 2 and is threadedly connected to the slide block 11. The motor provides power for the rotation of the threaded screw. The lifting drive component 12 can also be an electric cylinder or other equivalent components that can drive the slide block 11 to move up and down.

[0033] For details, please refer to Figure 1 A stirring assembly is installed on the slide 11. The stirring assembly includes a geared motor 13 fixedly installed on the slide 11, a stirring shaft 14 installed on the output shaft of the geared motor 13, and a stirring paddle 15 installed on the stirring shaft 14. Furthermore, the upper part of the medicine cartridge 18 is provided with an opening, and the stirring shaft 14 extends into the medicine cartridge 18 from the opening.

[0034] For details, please refer to Figure 1 The encapsulated spraying mechanism consists of two sets, which are symmetrically arranged on both sides of the support frame 2.

[0035] For details, please refer to Figure 1 or Figure 2 The boom 3 adopts a telescopic boom; furthermore, the telescopic boom can adopt a telescopic cylinder, a double-stage extension boom, a mechanical slide, or other equivalent components that can drive the U-shaped opening shell 4 to move laterally.

[0036] The vegetable sprayer provided in this embodiment uses a lifting drive 12 to move the slide 11 upwards, thereby changing the height of the U-shaped opening cover 4 to adapt to the pesticide spraying needs of solanaceous vegetables of different heights. It also facilitates the entry and exit of solanaceous vegetables into or out of the U-shaped opening cover 4. The two sets of enclosed spraying mechanisms can spray pesticides on two rows of solanaceous vegetables simultaneously, improving pesticide spraying efficiency. The boom 3 uses a telescopic arm, which can adaptively adjust the distance between the two enclosed spraying mechanisms to meet the pesticide spraying needs of solanaceous vegetables with different row spacings. When preparing the pesticide solution, the lifting drive 12 moves the slide 11 up and down, and the reduction motor 13 and the stirring shaft 14 move up and down synchronously with the slide 11. At the same time, the reduction motor 13 drives the stirring shaft 14 to rotate, and the stirring paddle 15 stirs the pesticide solution in the pesticide cylinder 18 synchronously. The stirring paddle 15 can thoroughly stir the pesticide solution in the pesticide cylinder 18 from top to bottom or from bottom to top to improve the mixing uniformity of the pesticide solution.

[0037] The process of using the vegetable sprayer provided by this utility model is as follows: The pesticide solution is injected into the pesticide cylinder 18, the lifting drive component 12 drives the slide 11 to move up and down, the reduction motor 13 drives the stirring shaft 14 to rotate, and the stirring paddle 15 stirs the pesticide solution in the pesticide cylinder 18 evenly. After the pesticide solution is prepared, the traveling cart 1 is pushed between two rows of solanaceous vegetables, the extension length of the telescopic arm is adjusted, and at the same time, the lifting drive component 12 drives the slide 11 to move up and down to adjust the height of the U-shaped opening shell 4 so that the height of the U-shaped opening shell 4 matches the height of the solanaceous vegetables. The traveling cart 1 moves, the pressure pump 19 injects the pesticide solution into the U-shaped liquid supply pipe 9, and then the pesticide solution enters the venturi tube 8 and the U-shaped spray pipe 5. Finally, the pesticide solution is sprayed out through the atomizing nozzle 6 and falls on the top and sides of the solanaceous vegetables, realizing the comprehensive spraying of the solanaceous vegetables. The excess pesticide solution falls into the collection tank 7 for recycling. The recycled pesticide solution can be used for subsequent spraying.
