Traditional pest and disease control methods mainly rely on manual spraying of pesticides, which requires a lot of labor, especially in large-scale planting areas. The operation is time-consuming and labor-intensive, and the spraying efficiency is low, which is difficult to meet the needs of large-scale production in modern agriculture;

[0027] Compared with the prior art, the present invention has the following beneficial effects:

[0028] 1. This device realizes automatic adjustment of the spraying height through the height adjustment module, and can dynamically adjust the spraying height according to the different growth stages of Solanaceae vegetables (such as seedling stage, flowering stage, and fruiting stage) to ensure that the liquid medicine evenly covers the crops. For example, in the seedling stage, the spraying height can be adjusted to a lower position to avoid waste of liquid medicine; in the fruiting stage, the spraying height can be adjusted to a higher position to ensure that the liquid medicine fully covers the fruit and leaves. This precise spraying method significantly improves the effect of pest control, reduces waste of liquid medicine, and reduces the cost of control;

For example, when proportioning the liquid medicine, the driving motor drives the liquid medicine stirring paddle through the transmission component B to fully mix the medicine and water. When spraying, the driving motor drives the liquid medicine stirring paddle to avoid precipitation of the medicine. This automatic proportioning and stirring function not only reduces manual intervention, but also ensures the uniformity and stability of the liquid medicine, and improves the reliability of the efficacy of the medicine;

[0030] 3. Through the power switching module, the device can flexibly switch between different working modes, such as spraying height adjustment, liquid medicine proportioning stirring and liquid medicine spraying, etc. For example, when the spraying height needs to be adjusted, the power switching module cuts off the power transmitted by the drive motor to the liquid medicine stirring paddle and the liquid medicine pump body, and only drives the height adjustment module to work; when the liquid medicine needs to be sprayed, the power switching module is switched so that the drive motor drives the liquid medicine stirring paddle and the liquid medicine pump body at the same time, ensuring that the liquid medicine is continuously stirred during the spraying process to prevent precipitation; when the liquid medicine needs to be proportioned, the power switching module is switched so that the drive motor only drives the liquid medicine stirring paddle to work, so as to achieve the mixing of medicine and water. This multifunctional integrated design significantly improves the practicality and ease of operation of the equipment;

[0031] 4. The device as a whole adopts a large number of mechanical structures to realize working control, which can reduce components such as control panels, thereby reducing the overall failure rate of the device and making it more durable. BRIEF DESCRIPTION OF THE DRAWINGS

[0079] When the manual knob 709 is turned, the large gear 713 can drive the small gear 712 to rotate, thereby achieving a speed-increasing effect, that is, manually rotating a smaller angle can make the adjusting worm 710 rotate multiple circles, and the rotation of the adjusting worm 710 can drive the adjusting worm wheel 711 to rotate, and finally the lead screw B708 ​​is rotated. When the lead screw B708 ​​rotates, the moving table 707 can pull the moving shaft 703 and the connecting turntable 701, so that the intermediate gear A806 (intermediate gear B906 or intermediate gear C1003) moves linearly, which makes the intermediate gear A 806 (intermediate gear B906 or intermediate gear C1003) is meshed or misaligned with the corresponding gear, that is, after the manual knob 709 is rotated forward by a specific angle, the lead screw B708 ​​can be rotated forward, and at this time, the motion platform 707 drives the intermediate gear A806 (intermediate gear B906 or intermediate gear C1003) to move linearly and disengage the transmission; after the manual knob 709 is rotated reversely by a specific angle, the lead screw B708 ​​can be rotated reversely, and at this time, the motion platform 707 can drive the intermediate gear A806 (intermediate gear B906 or intermediate gear C1003) to move linearly and connect the transmission;

[0080] When the moving platform 707 drives the intermediate gear A806 (intermediate gear B906 or intermediate gear C1003) to mesh with the corresponding gear, if the intermediate gear A806 (intermediate gear B906 or intermediate gear C1003) does not match the tooth groove of the corresponding output gear, the spring 704 will be compressed, and the self-locking effect of the adjusting worm 710 and the adjusting worm wheel 711 is used to prevent the rebound force of the spring 704 from acting in the opposite direction on the manual knob 709. When the driving motor 600 is working, the output gear will rotate. When the output gear rotates to make the tooth groove match the intermediate gear, the elastic force of the spring 704 will push the intermediate gear to move, and finally the intermediate gear and the output gear will be meshed. Such a structure can avoid hard contact between gears, improve the service life of the device, and reduce failures.

[0081] Further optimized, a position mark 714 is provided on the manual knob 709, and a state mark 715 is provided on the protective cover corresponding to each group of manual knobs 709, that is, when the manual knob 709 is turned so that the position mark 714 corresponds to a group of state marks 715, it means that the power is disconnected or transmitted at this time, and the state mark 715 here can be a mark bar combined with the words open and closed;

[0082] In addition, a control label 716 is provided on the protective cover corresponding to each set of manual knobs 709. The control label 716 is mainly used to indicate what kind of work the manual knob 709 is used to control, such as a spray height adjustment knob, a mixing ratio knob, or a spray control knob.

[0083] Furthermore, a normally open control button 717 is provided on the protective cover corresponding to each group of manual knobs 709, and a battery is fixedly connected to the mobile chassis. The battery, the control button 717, and the drive motor 600 are electrically connected. The corresponding control button 717 can be used to control the forward rotation, reverse rotation, and stop working of the drive motor 600. Among them, the control button 717 for controlling the spraying height adopts a momentary button, that is, when the control button 717 is pressed, the drive motor 600 rotates, and when it is released, the drive motor 600 stops. Among them, the control buttons 717 for controlling the proportioning stirring and spraying all adopt self-locking buttons, that is, when the control button 717 is pressed and released, the motor keeps working, and when it is pressed and released again, the motor stops working.
