An electric push rod 6 is fixed on the outer side of the fixed frame 3. The piston rod of the electric push rod 6 penetrates into the inner cavity of the fixed frame 3 and is fixedly connected with the rack frame 4. A long screw rod 7 is rotatably connected to the bottom of the fixed frame 3 through a bearing. A threaded sleeve 8 is fixed in the water tank 1. One end of the long screw rod 7 away from the fixed frame 3 penetrates into the inner cavity of the threaded sleeve 8 and is threadedly connected with the threaded sleeve 8. A full-automatic driving component 9 for rotating the long screw rod 7 is arranged on the top of the fixed frame 3. A spraying component 10 is arranged in the inner cavity of the water tank 1;

[0023] The angle and height of the spray head 103 are automatically adjusted through the electric push rod 6 and the driving motor 91 respectively, which facilitates timely adjustment of the position of the spray head 103 according to the growth conditions of the crops during the spraying operation, avoiding the need for manual operation of the adjustment structure on the traditional spraying device, resulting in the device needing to stop working. At the same time, the spray head 103 of the device can reciprocally swing within a certain range, enabling spraying of the crops at different angles, avoiding single-direction spraying and being unable to cover all parts of the plant, and improving the spraying efficiency.

[0024] The full-automatic driving component 9 includes a driving motor 91 fixed on the top of the fixed frame 3. The output shaft of the driving motor 91 penetrates into the inner cavity of the fixed frame 3 and is key-connected with a connecting shaft 92. The other end of the connecting shaft 92 is fixedly connected with the long screw rod 7. By driving the connecting shaft 92 to rotate through the driving motor 91, and then driving the long screw rod 7 through the connecting shaft 92, the long screw rod 7 rotates in the threaded sleeve 8 to adjust the height of the fixed frame 3.

[0025] The spraying component 10 includes a delivery pump 101 installed at the bottom of the inner wall of the water tank 1. The water outlet of the delivery pump 101 is communicated with a three-way hose 102. The two ends of the three-way hose 102 away from the delivery pump 101 are respectively communicated with two groups of inserting tubes 2. A spray head 103 is inserted into the top of the inserting tube 2. The liquid medicine in the water tank 1 is introduced into the inserting tube 2 from the three-way hose 102 through the delivery pump 101 and is conveyed upward to the spray head 103 for convenient spraying outward from the spray head 103.

[0026] Limit slots 11 are provided on both sides of the top and bottom of the inner cavity of the fixed frame 3. Limit blocks 12 are slidably connected in the inner cavities of the limit slots 11. The limit blocks 12 penetrate through the limit slots 11 and are fixed on the outer side of the rack frame 4. By sliding the limit blocks 12 in the limit slots 11, it is convenient to limit the rack frame 4, ensure the stability of the position of the rack frame 4, and at the same time enable the rack frame 4 to mesh with the gear 5.

[0027] A movable seat 13 is rotatably connected to the outside of the intubation tube 2, and a fixed seat 14 is fixed to the outside of the nozzle 103. The fixed seat 14 is threadedly connected to the movable seat 13. Through the cooperation of the movable seat 13 and the fixed seat 14, it is convenient to connect the nozzle 103 to the intubation tube 2, ensuring the stability of the connection between the nozzle 103 and the intubation tube 2.

[0028] A limiting ring 15 is fixed to the bottom of the outside of the intubation tube 2. The limiting ring 15 is located inside the water tank 1. Through the setting of the limiting ring 15, it is convenient to limit the intubation tube 2, preventing the long screw rod 7 from driving the fixed frame 3 to move upward, resulting in the intubation tube 2 being removed from the water tank 1 and the fixed frame 3 being unable to perform lifting adjustment anymore.

[0029] It further includes a controller 16 installed on the outside of the water tank 1. Support feet 17 and walking wheels 18 are installed at the bottom of the water tank 1. Through the setting of the controller 16, it is convenient for the operator to adjust the device, improving the flexibility of the device. At the same time, the setting of the support feet 17 is convenient for supporting the device, ensuring the stability of the device when it is stationary.

[0030] During specific use, prepare the liquid medicine to be sprayed in the water tank 1, and then push the device to move. According to the growth situation of the crops, it is necessary to adjust the position of the nozzle 103 irregularly. Control the electric push rod 6 and the drive motor 91 through the controller 16. Before spraying, select a suitable nozzle 103 and insert it into the intubation tube 2. Then, use the threaded connection between the movable seat 13 and the fixed seat 14 to install the nozzle 103 on the top of the intubation tube 2. The electric push rod 6 can drive the rack frame 4 to telescopically move inside the fixed frame 3. Then, the rack frame 4 drives the intubation tube 2 to rotate through the gear 5, causing the intubation tube 2 to drive the nozzle 103 to deflect. At the same time, start the motor to drive the connecting shaft 92 to rotate. The connecting shaft 92 drives the long screw rod 7 to rotate. Then, the long screw rod 7 rotates inside the threaded sleeve 8 to realize the adjustment of the height of the fixed frame 3, thereby adjusting the nozzle 103 installed on the intubation tube 2.
