A pesticide tank 2 is fixed to the top outer wall of the trolley 1, a delivery pump 6 is fixed to one side outer wall of the pesticide tank 2, the outlet of the delivery pump 6 is connected to the horizontal pipe 4 through a hose, and a filter assembly 21 is fixed to one side outer wall of the pesticide tank 2. The inlet of the filter assembly 21 is connected to the outlet of the delivery pump 6, and the outlet of the filter assembly 21 is connected to the inlet of the horizontal pipe 4.

[0021] Specifically, in this embodiment, a trolley 1 is included. A lifting mechanism 3 is provided on the top of the trolley 1. A horizontal pipe 4 is fixed to the top of the lifting mechanism 3. The bottom outer wall of the horizontal pipe 4 is connected to evenly distributed nozzles 5. When pesticide is introduced into the horizontal pipe 4, multiple nozzles 5 can spray pesticide. A pesticide tank 2 is fixed to the top outer wall of the trolley 1. The pesticide tank 2 contains pesticide. A delivery pump 6 is fixed to one side outer wall of the pesticide tank 2. The inlet of the delivery pump 6 is connected to the pesticide tank 2. The outlet of the delivery pump 6 is connected to the horizontal pipe 4 through a flexible hose. When the lifting mechanism 3 lifts and lowers the horizontal pipe 4, the flexible hose will not be pulled. A filter assembly 21 is fixed to one side outer wall of the pesticide tank 2. The filter assembly 21 is a prior art filter. The inlet of the filter assembly 21 is connected to the outlet of the delivery pump 6. The outlet of the filter assembly 21 is connected to the inlet of the horizontal pipe 4. The filter assembly 21 can filter impurities in the pesticide to prevent impurities from clogging the nozzles.

[0022] This utility model provides a pesticide spraying device for rice cultivation. The pesticide is delivered to the inside of the horizontal pipe 4 by the delivery pump 6, so that when the trolley 1 moves, the pesticide can be sprayed simultaneously onto the rice on both sides through multiple nozzles 5, thereby making the pesticide spraying of rice more efficient.

[0023] In another embodiment of this utility model, the lifting mechanism 3 includes a support cylinder 10, a lifting rod 11 is movably inserted into the support cylinder 10, a horizontal tube 4 is fixed to the top of the lifting rod 11, a screw 13 is connected to the inside of the support cylinder 10 via a bearing, the screw 13 is threadedly connected to the lifting rod 11, and the height of the lifting rod 11 can be adjusted when the screw 13 rotates; a mounting shell 12 is fixed to the top of the trolley 1, the support cylinder 10 is fixed to the top of the mounting shell 12, a worm gear 14 is fixed inside the mounting shell 12 at the bottom end of the screw 13, a worm 23 is connected to the bearing inside the mounting shell 12, the worm 23 meshes with the worm gear 14, and a handwheel 15 is fixed to the outside of the mounting shell 12 at one end of the worm 23. By rotating the handwheel 15, the handwheel 15 can drive the worm gear 14 and the screw 13 to rotate via the worm 23, thereby adjusting the height of the horizontal tube 4, so that the spraying height can be adjusted according to the growth height of the rice, thereby achieving the desired pesticide spraying effect. Ideally, a nut 18 is fixed to one outer wall of the support cylinder 10, and a stud 19 is threadedly connected inside the nut 18. A force-applying rod 20 is fixed to one end of the stud 19, allowing the stud 19 to rotate and thus engage and fix the lifting rod 11. A groove 17 is formed on one inner wall of the support cylinder 10, and a slider 16 is fixed to one outer wall of the lifting rod 11. The slider 16 slides within the groove 17, and the engagement between the slider 16 and the groove 17 allows for... The lifting rod 11 is more stable when moving up and down, and also prevents the lifting rod 11 from detaching from the support cylinder 10; the top outer wall of the medicine tank 2 is connected to a funnel 7, and the pesticide is added to the medicine tank 2 through the funnel 7. The top of the funnel 7 is equipped with a protective cover 8, which prevents dust from entering the medicine tank 2 through the funnel 7, and the protective cover 8 also has ventilation holes; two handrails 9 are fixed to one side outer wall of the trolley 1, and a pull rod 22 is fixed between the two handrails 9, which facilitates the pulling of the trolley 1.

[0024] Working principle: When adjusting the height of the horizontal tube 4, the handwheel 15 drives the worm gear 23 to rotate, which in turn drives the worm wheel 14 and the screw 13 to rotate. The rotation of the screw 13 raises the lifting rod 11, thereby adjusting the height of the horizontal tube 4. After mixing the pesticide and water, the mixture is poured into the pesticide tank 2 through the funnel 7. The pesticide in the pesticide tank 2 is then transported to the horizontal tube 4 by the delivery pump 6, allowing the nozzle 5 at the bottom of the horizontal tube 4 to spray the pesticide. Then, the trolley 1 is pulled between the rows of rice by the pull rod 22, so that the pesticide can be sprayed on both sides of the rice at the same time, making the pesticide spraying of rice more efficient.

[0025] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
