[0022] Specifically, the first servo motor 19 drives the trapezoidal lead screw 16 to rotate, the rotation of the trapezoidal lead screw 16 drives the lead screw seat 20 to rise and fall, and the rise and fall of the lead screw seat 20 drives the support block 12 to rise and fall.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention is a hand-push spraying device based on electrostatic spraying. The top of the support block 12 is provided with an installation groove. The top of the installation groove is rotatably connected to a rotating shaft 24. The top of the rotating shaft 24 is fixedly connected to the center of the bottom of the mounting base 13. The bottom of the rotating shaft 24 is fixedly provided with a bevel gear A22.

The bevel gear B23 meshes with the bevel gear A22.

[0024] Specifically, the second servo motor 21 drives the bevel gear B23 to rotate, and the bevel gear B23 meshes with the bevel gear A22, thereby driving the rotating shaft 24 to rotate, and the rotating shaft 24 drives the mounting base 13 to rotate.

[0025] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention is a hand-push spraying device based on electrostatic spraying. The top of the mounting base 13 is provided with a mounting groove, the mounting block 11 is nested and connected with the mounting groove, and both sides of the mounting groove are provided with locking posts 14.

[0031] In specific implementation, when using this hand-push spraying device, firstly connect the material pump 5, the first servo motor 19, and the second servo motor 21 to the vehicle power supply via the vehicle switch. Firstly, embed the assembly block 11 at the bottom of the spray bar 8 into the assembly slot at the top of the assembly base 13, and fix it by engaging the locking post 14 with the locking hole 25. Next, adjust the height of the electrostatic nozzle 9 according to the height of the vegetation to be sprayed. The model of the electrostatic nozzle 9 is "LONDA". Then, turn on the first servo motor 19, which drives the trapezoidal lead screw 16 to rotate. The trapezoidal lead screw 16 drives the lead screw seat 20 to rise and fall. The rise and fall of the lead screw seat 20 drives the support block 12 to rise and fall. Then, turn on the material pump 5 and the second servo motor 21. The material pump 5 draws out the liquid medicine from the storage tank 3 and sprays it out through the electrostatic nozzle 9. During the spraying process, the second servo motor 21 drives the rotating shaft 24 to rotate back and forth through the bevel gear A22 and bevel gear B23. The reciprocating rotation of the rotating shaft 24 drives the assembly base 13 to rotate, thereby driving the spray bar 8 to swing back and forth for spraying.
