Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 4 , a precision pesticide application device for preventing and controlling diseases and insect pests of sour jujube trees, comprising:

[0023] A support rod 1, a fixed block 3 is fixedly connected to the top of the support rod 1, a fixed medicine box 4 is fixedly connected to the top of the fixed medicine box 4, a spraying chamber 5 is fixedly connected to the top of the fixed medicine box 4, a spraying device is arranged in the spraying chamber 5, and is used to spray the liquid medicine. The spraying device is an existing device, so its working principle is not described in detail. A connecting groove 20 is provided between the spraying chamber 5 and the spraying pipe 6, a spraying pipe 6 is fixedly connected to the side wall of the spraying chamber 5, and a fixed nozzle 7 is fixedly connected to the end of the spraying pipe 6. The liquid medicine is sent into the fixed medicine box 4 and enters the spraying chamber 5, and then is sprayed out through the spraying pipe 6 and the fixed nozzle 7;

[0024] The feeding structure includes a fixed cavity 8 opened on the inner side of 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 rod 11 is threadedly sleeved on the rotating rod 10, the threaded sleeve rod 11 passes through the inner wall of the fixed cavity 8 and the fixed medicine box 4 and extends to the interior of the fixed medicine box 4, one end of the threaded sleeve rod 11 located inside the fixed medicine box 4 is fixedly connected to a piston plate 19, and an adjustment structure is installed in the fixed cavity 8;

[0025] The servo motor 9 is started, and the servo motor 9 runs for a period of time according to the set program. The output end of the servo motor 9 drives the rotating rod 10 to rotate, while the threaded sleeve 11 cannot rotate under the action of the adjustment structure, so the threaded sleeve 11 moves upward, and when the threaded sleeve 11 moves, it drives the piston plate 19 to move upward together, so that the liquid medicine is squeezed into the spray chamber 5;

[0026] The adjusting structure includes a sliding sleeve 12 which is slidably sleeved on the outer side of the threaded sleeve rod 11, the top of the sliding sleeve 12 is rotatably connected to the upper inner wall of the fixed cavity 8, the outer side of the fixed block 17 is fixedly sleeved with a fixed block 17, the upper inner wall of the support rod 1 is fixedly connected with a mounting plate 22, the bottom end of the mounting plate 22 is slidably connected with a movable plate 21, the bottom end of the mounting plate 22 is fixedly connected with a sliding block 23, a sliding groove 24 matching the sliding block 23 is provided on the movable plate 21, a connecting spring 25 is fixedly connected to the side wall of the sliding block 23, one 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 tooth 18 is fixedly connected to the side wall of the movable plate 21, the shape and position of the fixed tooth 18 are matched with the fixed block 17, in the initial state, the fixed tooth 18 is engaged with the fixed block 17, so that the fixed block 17 cannot rotate, a pushing block 16 is fixedly connected to the bottom end of the movable plate 21, and a pushing structure is installed on the inner side of the fixed cavity 8;

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

[0028] The pushing structure includes a reciprocating screw rod sleeve rod 13 rotatably connected to the lower inner wall of the fixed cavity 8, a connecting rod 14 is arranged on the inner side of the reciprocating screw rod sleeve rod 13, the connecting rod 14 is mechanically matched with the reciprocating screw rod sleeve rod 13 through a screw slider, the connecting rod 14 extends to the outer side of the reciprocating screw rod sleeve rod 13, and the connecting rod 14 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, the length of the connecting rod 14 also corresponds to the pushing block 16, the reciprocating screw rod sleeve rod 13 and the rotating rod 10 are mutually connected through a belt transmission assembly 15, and the side walls of the pushing block 16 and the connecting rod 14 are both provided with rounded corners to facilitate mutual extrusion between the two;

[0029] Under the action of the belt transmission assembly 15, the reciprocating screw rod 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 rod sleeve 13. When the connecting rod 14 moves upward, the connecting rod 14 will eventually contact and squeeze the pushing block 16, thereby pushing the pushing block 16 to move outward, driving the moving plate 21 to move together, and deforming the connecting spring 25. 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 groove 20, and the electromagnetic control valve is connected to the servo motor 9. The electromagnetic control valve and the servo motor 9 are started and closed synchronously, so the amount of liquid medicine that passes through the connecting groove 20 and enters the spraying chamber 5 each time is the same, so as to facilitate precise application of medicine; the side wall of the fixed medicine box 4 is fixedly connected with a medicine inlet pipe, and the medicine inlet pipe is installed at the top of the side wall of the fixed medicine box 4, so as to add liquid medicine into the fixed medicine box 4;

[0032] In the present invention, when the device is in use, the servo motor 9 and the electromagnetic control valve are started at a set time according to a set program. After the servo motor 9 is started, the output end of the servo motor 9 drives the rotating rod 10 to rotate, and at this time, the fixed clamping block 17 is engaged with the fixed clamping tooth 18, and the threaded sleeve 11 cannot rotate, so the threaded sleeve 11 will move upward, and when the threaded sleeve 11 moves, it will drive the piston plate 19 to move upward together, squeezing the liquid medicine into the spraying chamber 5, and 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] At the same time, under the action of the belt transmission assembly 15, the reciprocating screw rod 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 rod sleeve 13. When the connecting rod 14 moves upward, the connecting rod 14 will eventually contact and squeeze the pushing block 16, thereby pushing the pushing block 16 to move outward, driving the moving plate 21 to move together, and deforming the connecting spring 25. 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 movable plate 21 moves outward, it will drive the fixed teeth 18 to move accordingly, so that the fixed teeth 18 are 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 both rotate. When the threaded sleeve 11 rotates, it will drive the piston plate 19 to rotate together, so that the fixed medicine box 4 rotates together. When the fixed medicine box 4 rotates, the spray chamber 5 and other structures rotate together, so that the medicine liquid can be sprayed all around, greatly expanding the range of the device spraying the medicine liquid, and then the movable plate 21 moves back, so that the fixed teeth 18 and the fixed block 17 are engaged together again, so that the threaded sleeve 11 cannot rotate, so as to facilitate the next spraying of the medicine liquid.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
