Description

Technical Field

[0001] This utility model relates to the field of pesticide spraying technology, specifically a pesticide spraying machine that is easy to adjust. Background Technology

[0002] After wheat seedlings emerge, diseases, pests, and weeds occur frequently throughout the entire growth period. In order to remove weeds and pests, it is necessary to spray pesticides on the wheat fields from time to time. Specifically, workers walk along the field ridges or ditches and carry sprayers to spray pesticides on the wheat fields. However, the existing technology has a small spraying area when spraying pesticides on wheat fields, which is inconvenient to adjust and reduces work efficiency.

[0003] For example, a wheat spraying machine described in patent CN220630801U includes a pesticide storage tank, a pipe, and a nozzle. The spraying machine can be moved along the field ridges or ditches by rollers, requiring only pushing to move it. At the same time, a drive motor causes the pipe to rotate back and forth, thereby spraying pesticide on different areas. However, during the spraying process, when the drive motor drives the pipe to rotate back and forth, the frequent back and forth rotation not only makes it difficult to control the balance of the device, but also reduces the stability of the connection between the pipe and the pesticide storage tank, thus reducing the practicality of the device.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-5 As shown, an easily adjustable sprayer includes a mounting plate 1. A handle 11 is fixedly connected to the outer wall of the mounting plate 1. A movable wheel 12 is provided at the bottom end of the mounting plate 1. A fixing rod 13 is fixedly connected to the outer wall of the mounting plate 1. An auxiliary wheel 14 is provided at the end of the fixing rod 13. A lifting mechanism 2 is provided on the inner wall of the mounting plate 1. A limit mechanism 3 is symmetrically provided at the top of the lifting mechanism 2. Folding components 4 are symmetrically provided on both sides of the lifting mechanism 2.

[0027] In this embodiment, the moving wheels 12 and auxiliary wheels 14 make the device easier to move. The lifting mechanism 2 can adjust the height of the nozzle to accommodate wheat of different heights. The combination of the limiting mechanism 3, the folding assembly 4 and the positioning mechanism 5 can expand the spraying range of the nozzle, thereby improving work efficiency. After spraying, the connecting pipe 27 and the protective rod 28 can be folded to reduce the space occupied by the device.

[0028] In an optional embodiment, such as Figure 2 and Figure 3 As shown, the lifting mechanism 2 includes a first lead screw 21. The outer wall of the first lead screw 21 is rotatably connected to the inner wall of the mounting plate 1. A mounting block 22 is threadedly connected to the outer wall of the first lead screw 21. A medicine storage tank 23 is fixedly connected to the outer wall of the mounting block 22. A submersible pump 24 is fixedly connected to the inner wall of the medicine storage tank 23. An infusion tube 25 is fixedly connected to the output end of the submersible pump 24. The infusion tube 25 passes through the outer wall of the medicine storage tank 23 and is connected to a rectangular tube 26. The bottom end of the rectangular tube 26 is fixedly connected to the top end of the medicine storage tank 23. Rotating the first lead screw 21 drives the mounting block 22 to move, and the mounting block 22 drives the medicine storage tank 23 to move together. The device moves step by step, causing the storage tank 23 to move synchronously with the rectangular tube 26 and the connecting tube 27. When the connecting tube 27 is at a suitable height, the first screw 21 is stopped, and then the submersible pump 24 is started to extract the pesticide from the storage tank 23 and deliver it to the rectangular tube 26 through the infusion tube 25. The rectangular tube 26 then delivers it to the connecting tube 27, where it is sprayed out by the nozzle on the connecting tube 27. Then, the mounting plate 1 is pushed, causing the moving wheels 12 and the auxiliary wheels 14 to move within the field ridges, driving the connecting tube 27 and its nozzle to move synchronously, thereby spraying the pesticide onto the wheat plants to achieve the effect of spraying pesticide solution.

[0029] In an optional embodiment, such as Figure 2As shown, the rectangular tube 26 is rotatably connected to the left and right ends of the first rotating shaft 29. The outer wall of the first rotating shaft 29 is fixedly connected to the protective rod 28, and the inner wall of the protective rod 28 is fixedly connected to the connecting pipe 27. The connecting pipe 27 is connected to the rectangular tube 26. The outer wall of the connecting pipe 27 is evenly distributed with nozzles, and the connecting pipe 27 can be bent and folded. By removing the restriction of the limiting mechanism 3 on the first rotating shaft 29, the protective rod 28 can be rotated to extend the protective rod 28, so that the connecting pipe 27 can cover a larger area of ​​wheat field.

[0030] In an optional embodiment, such as Figure 2 and Figure 4 As shown, the limiting mechanism 3 includes two fixed plates 31. The outer wall of the fixed plate 31 is fixedly connected to the outer wall of the rectangular tube 26. The inner wall of the fixed plate 31 is rotatably connected to a second lead screw 32. One end of the second lead screw 32 is rotatably connected to a locking tooth 33. The outer wall of the locking tooth 33 is symmetrically fixedly connected to a guide rod 34. The outer wall of the guide rod 34 is slidably connected to a groove opened in the outer wall of the fixed plate 31. The teeth of the locking tooth 33 mesh with a gear 35. The axis of the gear 35 is fixedly connected to the outer wall of the first rotating shaft 29. Rotating the second lead screw 32 causes the locking tooth 33 to drive the guide rod 34 to slide in the groove opened in the outer wall of the fixed plate 31. The guide rod 34 guides the locking tooth 33, so that the locking tooth 33 can only move horizontally and cannot rotate. This causes the locking tooth 33 to move away from the gear 35, thus removing the restriction on the gear 35 and the first rotating shaft 29.

[0031] In an optional embodiment, such as Figure 2 and Figure 5 As shown, the folding assembly 4 includes two guide rails 41. The outer wall of the guide rail 41 is fixedly connected to the outer wall of the medicine storage tank 23. A guide block 42 is slidably connected in a groove opened in the outer wall of the guide rail 41. A second rotating shaft 43 is fixedly connected to the outer wall of the guide block 42. A fixing bolt 44 is threadedly connected to the inner wall of the second rotating shaft 43. The fixing bolt 44 passes through the guide block 42 and contacts the inner wall of the guide rail 41. A first movable rod 45 is rotatably connected to the outer wall of the second rotating shaft 43. A positioning mechanism 5 is rotatably connected to the inner wall of the first movable rod 45. A second movable rod is rotatably connected to the outer wall of the first movable rod 45. 46. ​​The outer wall of the second movable rod 46 is rotatably connected to the outer wall of the protective rod 28. By rotating the fixing bolt 44, the fixing bolt 44 is no longer in contact with the inner wall of the guide rail 41. At the same time, the positioning mechanism 5 is removed from the positioning between the second movable rod 46 and the first movable rod 45. Then, the protective rod 28 is rotated, which drives the guide block 42 to slide in the groove. When the guide block 42 moves to the appropriate position, the fixing bolt 44 is tightened again, so that the end of the fixing bolt 44 is in close contact with the inner wall of the guide rail 41. This restricts the position of the guide block 42 and prevents the guide block 42 from sliding.

[0032] In an optional embodiment, such as Figure 5 and Figure 6 As shown, the positioning mechanism 5 includes a connecting rod 51. The outer wall of the connecting rod 51 is rotatably connected to the inner wall of the first movable rod 45, and the outer wall of the connecting rod 51 is fixedly connected to the inner wall of the second movable rod 46. A sliding rod 52 is slidably connected to the inner wall of the connecting rod 51. A pull plate 53 is fixedly connected to the end of the sliding rod 52. Positioning blocks 54 are evenly fixedly connected to the outer wall of the pull plate 53. The positioning blocks 54 are inserted into the positioning holes opened on the outer wall of the second movable rod 46. A spring 55 is fixedly connected to the other end of the sliding rod 52. One end of the spring 55 is fixedly connected to the inner wall of the connecting rod 51. By pulling the pull plate 53, the spring 55 is stretched, and the insertion of the positioning block 54 into the positioning hole is canceled.

[0033] In an optional embodiment, such as Figure 5 and Figure 6 As shown, the slide bar 52 has a T-shaped structure, consisting of a cylindrical part and a rectangular block part. The groove opened on the inner wall of the connecting rod 51 is adapted to the rectangular block. Under the action of the slide bar 52 structure, when the second movable rod 46 drives the connecting rod 51 to rotate, and the positioning block 54 is not inserted into the positioning hole, the connecting rod 51 needs to drive the slide bar 52 to rotate synchronously under the action of the rectangular block.

[0034] The above embodiment discloses an easily adjustable sprayer. In use, rotating the fixing bolt 44 moves its end away from the inner wall of the guide rail 41. Then, rotating the second lead screw 32 moves the locking teeth 33 away from the gear 35. Next, pulling the pull plate 53 stretches the spring 55, releasing the insertion of the positioning block 54 into the positioning hole. Then, rotating the protective rod 28 extends it, causing the second movable rod 46 and the first movable rod 45 to rotate. The first movable rod 45 drives the guide block 42 to slide within the groove. When the protective rod 28 is at a suitable angle, the positioning block 54 automatically re-inserts into the positioning hole under the reset action of the spring 55. Then, the locking teeth 33's restriction on the gear 35 (by reversing the rotation of the second lead screw 32) and the fixing bolt 44's restriction on the guide block 42 are locked sequentially (by tightening the fixing bolt 44). Then, according to the current wheat height, rotating the first lead screw 21 drives the mounting block 22 to move, and the mounting block 22 moves the pesticide storage tank 23 synchronously. The device moves synchronously with the storage tank 23, which in turn moves the rectangular tube 26 and the connecting tube 27. Once the connecting tube 27 is at a suitable height, the first screw 21 stops rotating, and the submersible pump 24 is then started to extract the pesticide from the storage tank 23. The pesticide is then transported to the rectangular tube 26 via the infusion tube 25, and then from the rectangular tube 26 to the connecting tube 27, where it is sprayed out by the nozzle on the connecting tube 27. Subsequently, the mounting plate 1 is pushed, causing the moving wheels 12 and the auxiliary wheels 14 to move within the field ridges, thus moving the connecting tube 27 and its nozzle synchronously and spraying the pesticide onto the wheat plants. In summary, the moving wheels 12 and the auxiliary wheels 14 make the device easier to move. The lifting mechanism 2 can adjust the height of the nozzle to accommodate wheat of different heights. The combination of the limiting mechanism 3, the folding assembly 4, and the positioning mechanism 5 can expand the spraying range of the nozzle, improving work efficiency. After spraying, the connecting tube 27 and the protective rod 28 can be folded to reduce the space occupied by the device.

[0035] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
