In order to avoid the threat of diseases and pests to jujube trees, pest and disease control measures are required, thus necessitating a pest and disease control application device.

[0003] Existing precision spraying devices for pest and disease control are difficult to apply accurately, resulting in insufficient or excessive spraying, which negatively impacts the growth of jujube trees. Furthermore, the spraying range of existing devices is insufficient, requiring multiple spraying devices to complete the application in jujube orchards, leading to poor economic efficiency and hindering the use of these devices. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the difficulty in accurately applying pesticide solutions, resulting in insufficient or excessive application of pesticide solution, which negatively impacts the growth of jujube trees. Additionally, existing devices have insufficient spraying range, requiring multiple spraying devices in jujube orchards to complete pesticide application, leading to poor economic efficiency and hindering device usability. Therefore, this invention proposes a precision pesticide application device for the prevention and control of diseases and pests in jujube trees.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0022] Referring to Figures 1-4, a precision application device for controlling diseases and pests of jujube trees includes:

[0023] A support rod 1 is provided, and a fixing block 3 is fixedly connected to the top of the support rod 1. A fixing medicine tank 4 is fixedly connected to the top of the fixing block 3. A spraying chamber 5 is fixedly connected to the top of the fixing medicine tank 4. A spraying device is provided inside the spraying chamber 5 to spray out the medicine. The spraying device is existing equipment, so its working principle will not be described in detail. A connecting groove 20 is provided between the spraying chamber 5 and the spraying pipe 6. The spraying pipe 6 is fixedly connected to the side wall of the spraying chamber 5. A fixing nozzle 7 is fixedly connected to the end of the spraying pipe 6. The medicine is sent into the fixing medicine tank 4 and then into the spraying chamber 5, and then sprayed out through the spraying pipe 6 and the fixing nozzle 7.

[0024] The feeding structure includes a fixed cavity 8 opened inside the fixed block 3. A servo motor 9 is fixedly connected to the lower inner wall of the fixed cavity 8. A rotating rod 10 is fixedly connected to the output end of the servo motor 9. A threaded sleeve 11 is threaded onto the rotating rod 10. The threaded sleeve 11 passes through the inner wall of the fixed cavity 8 and the fixed medicine box 4 and extends into the interior of the fixed medicine box 4. A piston plate 19 is fixedly connected to one end of the threaded sleeve 11 inside the fixed medicine box 4. An adjustment structure is installed inside the fixed cavity 8.

[0025] Start the servo motor 9. The servo motor 9 runs according to the set program for a period of time. The output end of the servo motor 9 drives the rotating rod 10 to rotate. However, the threaded sleeve rod 11 cannot rotate under the action of the adjustment structure. Therefore, the threaded sleeve rod 11 will move upward. When the threaded sleeve rod 11 moves, it will drive the piston plate 19 to move upward together, squeezing the liquid medicine into the spraying chamber 5.

[0026] The adjustment structure includes a sliding sleeve 12 that is slidably sleeved on the outside of the threaded sleeve rod 11. The top end of the sliding sleeve 12 is rotatably connected to the upper inner wall of the fixed cavity 8. A fixed locking block 17 is fixedly sleeved on the outside of the sliding sleeve 12. An installation plate 22 is fixedly connected to the upper inner wall of the support rod 1. A moving plate 21 is slidably connected to the bottom end of the installation plate 22. A sliding block 23 is fixedly connected to the bottom end of the installation plate 22. A sliding groove 24 matching the sliding block 23 is opened on the moving plate 21. A connecting spring 25 is fixedly connected to the side wall of the sliding block 23. The end of the connecting spring 25 away from the sliding block 23 is fixedly connected to the inner wall of the sliding groove 24. A fixed locking tooth 18 is fixedly connected to the side wall of the moving plate 21. The shape and position of the fixed locking tooth 18 are matched with the fixed locking block 17. In the initial state, the fixed locking tooth 18 and the fixed locking block 17 are engaged together, so that the fixed locking block 17 cannot rotate. A pushing block 16 is fixedly connected to the bottom end of the moving plate 21. A pushing structure is installed on the inner side of the fixed cavity 8.

[0027] Under the action of the pushing structure, the moving plate 21 will move outward, causing the fixed tooth 18 to move accordingly, so that the fixed tooth 18 is separated from the fixed block 17. At this time, the fixed block 17 can rotate, so the sliding sleeve 12 and the threaded sleeve 11 can rotate. When the threaded sleeve 11 rotates, it will drive the piston plate 19 to rotate together, so that the fixed medicine box 4 will rotate together. When the fixed medicine box 4 rotates, the spraying chamber 5 and other structures will rotate together, so that the medicine can be sprayed in all directions, greatly expanding the range of the device spraying medicine.

[0028] The pushing structure includes a reciprocating lead screw sleeve 13 rotatably connected to the lower inner wall of the fixed cavity 8. A connecting rod 14 is provided on the inner side of the reciprocating lead screw sleeve 13. The connecting rod 14 is mechanically engaged with the reciprocating lead screw sleeve 13 through a lead screw slider. The connecting rod 14 extends to the outer side of the reciprocating lead screw sleeve 13 and is slidably connected to the inner wall of the fixed cavity 8 through a sliding bracket. The position of the connecting rod 14 corresponds to the pushing block 16, and the length of the connecting rod 14 also corresponds to the pushing block 16. The reciprocating lead screw sleeve 13 and the rotating rod 10 are connected to each other through a belt drive assembly 15. The side walls of the pushing block 16 and the connecting rod 14 are both provided with rounded corners to facilitate mutual compression between the two.

[0029] Under the action of the belt drive assembly 15, the reciprocating screw sleeve 13 will rotate together with the rotating rod 10, while the connecting rod 14 cannot rotate. Therefore, the connecting rod 14 will move up and down with the rotation of the reciprocating screw sleeve 13. When the connecting rod 14 moves upward, the connecting rod 14 will eventually come into contact with and squeeze the pushing block 16, thereby pushing the pushing block 16 to move outward, driving the moving plate 21 to move together, causing the connecting spring 25 to deform. When the connecting rod 14 moves downward, under the action of the elastic force of the connecting spring 25, the pushing block 16 and the moving plate 21 return to their original positions.

[0030] An electromagnetic control valve is fixedly installed on the inner side of the connecting channel 20. The electromagnetic control valve is connected to the servo motor 9. The electromagnetic control valve and the servo motor 9 start and close synchronously. Therefore, the amount of liquid medicine entering the spraying chamber 5 through the connecting channel 20 each time is the same, so as to facilitate precise application of medicine. A medicine inlet pipe is fixedly connected to the side wall of the fixed medicine tank 4. The medicine inlet pipe is installed at the top of the side wall of the fixed medicine tank 4 so as to add liquid medicine to the fixed medicine tank 4.

[0031] The bottom end of the support rod 1 is fixedly connected to the fixed base 2, which is fixedly connected to the ground by fixing bolts, making the installation of the device more convenient. The spray pipe 6 and the fixed nozzle 7 are set at an upward angle, so that the sprayed liquid will spray upward first and then fall down under the action of gravity, so that the liquid can be sprayed over a wider area.

[0032] In this invention, when the device is in use, the servo motor 9 and the electromagnetic control valve start at set times according to the pre-set program. After the servo motor 9 starts, the output end of the servo motor 9 drives the rotating rod 10 to rotate. At this time, the fixed locking block 17 meshes with the fixed locking tooth 18, and the threaded sleeve rod 11 cannot rotate. Therefore, the threaded sleeve rod 11 will move upward. When the threaded sleeve rod 11 moves, it will drive the piston plate 19 to move upward together, squeezing the liquid medicine into the spraying chamber 5. The liquid medicine entering the spraying chamber 5 is sprayed out through the spraying pipe 6 and the fixed nozzle 7 under the action of the spraying device.

[0033] Meanwhile, under the action of the belt drive assembly 15, the reciprocating screw sleeve 13 will rotate together with the rotating rod 10, while the connecting rod 14 cannot rotate. Therefore, the connecting rod 14 will move up and down with the rotation of the reciprocating screw sleeve 13. When the connecting rod 14 moves upward, the connecting rod 14 will eventually come into contact with and squeeze the pushing block 16, thereby pushing the pushing block 16 to move outward, driving the moving plate 21 to move together, causing the connecting spring 25 to deform. When the connecting rod 14 moves downward, under the action of the elastic force of the connecting spring 25, the pushing block 16 and the moving plate 21 return to their original positions.

[0034] When the moving plate 21 moves outward, it will cause the fixed locking teeth 18 to move accordingly, causing the fixed locking teeth 18 to separate from the fixed locking block 17. At this time, the fixed locking block 17 can rotate, so the sliding sleeve 12 and the threaded sleeve rod 11 can both rotate. When the threaded sleeve rod 11 rotates, it will drive the piston plate 19 to rotate together, causing the fixed medicine tank 4 to rotate together. When the fixed medicine tank 4 rotates, the spraying chamber 5 and other structures will rotate together, so that the medicine can be sprayed in all directions, greatly expanding the spraying range of the device. Then the moving plate 21 moves back, causing the fixed locking teeth 18 and the fixed locking block 17 to engage again, preventing the threaded sleeve rod 11 from rotating, so that the medicine can be sprayed again.

[0035] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
