[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-6 In this embodiment, a spraying device for a pesticide sprayer includes two sets of support plates 25, a base plate 11, and a water tank 29 fixedly connected to the top of the base plate 11. Two sets of support columns 12 are fixedly connected to each of the two sets of base plates 11. An extension plate 13 is slidably connected inside the support column 12. A limiting component for positioning the extension plate 13 is provided on the support column 12.

[0028] The limiting assembly includes a fixing plate 15 and a positioning plate 14. The fixing plate 15 is fixedly connected to the support column 12, and the positioning plate 14 is fixedly connected to the top of the support column 12. A sliding groove 18 is provided on the top of the positioning plate 14. An extension plate 13 is located between the positioning plate 14 and the fixing plate 15. A limiting plate 17 is slidably connected in the sliding groove 18. The extension plate 13 has several sets of limiting holes 16 for the limiting plate 17 to pass through. A slot 22 is provided on one side of the fixing plate 15 for the limiting plate 17 to engage. The slot 22 is provided with a limiting device. The fixing member for positioning plate 17 is released from the restriction of the limiting plate 17, pushing the limiting plate 17 to slide in the slide groove 18 and disengage from the limiting hole 16, pushing the support plate 25, and causing the extension plate 13 to slide upward in the support column 12. After sliding to the appropriate position at the top of the agricultural plant, the limiting plate 17 is pushed to slide in the slide groove 18, passing through the corresponding limiting hole 16 and locking into the slot 22. The fixing member fixes the limiting plate 17. The extension plate 13 is adjusted according to the height of the agricultural plant, which can avoid the phenomenon of plant breakage or root loosening caused by collision with the agricultural plant.

[0029] The bottom of the two sets of support plates 25 is fixedly connected to the two sets of extension plates 13 set on the top of the base plate 11, and the support plate 25 is slidably connected to the extension plate 26; the bottom of the two sets of extension plates 26 is fixedly connected to the two sets of extension plates 13 set on the top of the other base plate 11, and the top of the water tank 29 is provided with a spraying assembly.

[0030] The fixing component includes a groove 19 and an arc-shaped locking block 21. The groove 19 is formed on the top of the limiting plate 17. The arc-shaped locking block 21 is slidably connected within the groove 19. A compression spring 20 is connected to the bottom of the arc-shaped locking block 21. The end of the compression spring 20 away from the arc-shaped locking block 21 is connected to the bottom of the inner wall of the groove 19. The arc-shaped locking block 21 is engaged within a locking groove 22. A pressing plate 23 overlaps the top of the arc-shaped locking block 21. A pressing rod 24 is fixedly connected to the top of the pressing plate 23. The pressing rod 24 is slidably connected to the fixing plate 15. A pressing spring is sleeved on the extrusion rod 24. During the sliding process, the arc-shaped locking block 21 is pressed by one side of the extension plate 13 into the groove 19, which presses the compression spring 20. After it is inserted into the slot 22, the elastic force of the compression spring 20 is used to pop out the arc-shaped locking block 21. The top of the arc-shaped locking block 21 contacts the bottom of the extrusion plate 23, which facilitates the positioning of the limiting plate 17 and reduces the risk of the limiting plate 17 disengaging from the limiting hole 16, causing the extension plate 13 to slide downward in the support column 12, thereby driving the support plate 25 and the extension plate 26 to move downward, which could damage the agricultural plants.

[0031] The support plate 25 has a positioning hole 28, and a bolt is threaded into the positioning hole 28. The extension plate 26 has several sets of fixing holes 27 for threaded connection with the bolt. A snap-fit ​​plate is fixedly connected to one end of the extension plate 26 near the support plate 25. Using a tool, the two sets of bolts are rotated to disengage them from the fixing holes 27, and a set of base plates 11 is pushed to make the extension plate 26 slide within the support plate 25. After sliding to a suitable position, the two sets of bolts are rotated again to fix the sliding of the extension plate 26, which facilitates positioning the distance between the two sets of base plates 11 and prevents the two sets of base plates 11 from tipping over.

[0032] The spraying assembly includes two sets of fixed pipes 32 and a telescopic hose 31. The fixed pipes 32 are located on the top of the water tank 29. The outlet of the telescopic hose 31 is connected to the inlet of the fixed pipe 32. Several sets of spray heads are provided on one side of the fixed pipe 32. The water tank 29 is fixedly connected between two sets of support columns 12 on the top of a base plate 11. Support frames 30 are fixedly connected to both sides of the fixed pipe 32. Support frames 30 are fixedly connected to the top of the two sets of support plates 25 and the top of the two sets of extension plates 26. When the pesticide is poured into the water tank 29 through the water inlet and the base plate 11 is moved, the water pump in the water tank 29 delivers the pesticide through the telescopic hose 31 to the fixed pipe 32, and sprays it out from the spray head on one side of the fixed pipe 32, which facilitates the spraying of pesticides on agricultural plants.

[0033] A water inlet is provided on one side of the water tank 29, which facilitates the injection of the prepared medicine into the water tank 29.

[0034] The bottom of the base plate 11 is equipped with several sets of casters. By setting the casters, it is easy to push the base plate 11 and move the entire device so as to spray pesticides on agricultural plants.

[0035] The working principle of this utility model is as follows: When in use, first adjust the distance between the two sets of base plates 11 according to the distance between the ridges, use a tool to rotate the two sets of bolts to disengage them from the fixing holes 27, push one set of base plates 11 to make the extension plate 26 slide within the support plate 25, and when it slides to a suitable position, use a tool to rotate the two sets of bolts to fix the sliding of the extension plate 26.

[0036] Next, adjust the extension plate 13 according to the height of the agricultural plant. First, press down on the four sets of extrusion rods 24, causing the extrusion rods 24 to press down on the spring, which in turn causes the extrusion plate 23 to slide in the slot 22 and extrude on the arc-shaped locking block 21. The arc-shaped locking block 21, under pressure, slides downward in the groove 19 and extrudes on the compression spring 20, pushing the limiting plate 17 to slide in the slide groove 18 and disengage from the limiting hole 16. This pushes the support plate 25 and causes the extension plate 13 to slide upward in the support column 12. After sliding to the appropriate position at the top of the agricultural plant, push the limiting plate 17 to slide in the slide groove 18, passing through the corresponding... The limiting hole 16 is inserted into the slot 22. During the sliding process, the arc-shaped block 21 is squeezed in the groove 19 by the extension plate 13 and squeezes the compression spring 20. After being inserted into the slot 22, the elastic force of the compression spring 20 is used to pop out the arc-shaped block 21, and the top of the arc-shaped block 21 contacts the bottom of the pressing plate 23. The two sets of bottom plates 11 are adjusted according to the spacing between the ridges, and the support plate 25 is adjusted according to the height of the agricultural plants. This can avoid the phenomenon of the plant breaking or the roots loosening due to the collision of the bottom plate 11 being too low, and avoid mechanical damage to the agricultural plants, which will affect the normal growth of the crops.

[0037] When spraying pesticides, the pesticide solution is poured into the water tank 29 through the water inlet. When the base plate 11 is moved, the water pump in the water tank 29 delivers the pesticide solution to the fixed pipe 32 through the telescopic hose 31, and sprays it out from the spray head on one side of the fixed pipe 32 to spray pesticides on agricultural plants.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
