One end of the electric push rod 701 is fixedly connected to a folding tube 705, and one end of the folding tube 705 is fixedly connected to the connecting plate 702. The output end of the electric push rod 701 is located in the folding tube 705, and the folding tube 705 will stretch as the connecting plate 702 moves, thereby preventing foreign matter from adhering to the output end of the electric push rod 701 and affecting the normal operation of the electric push rod 701. A pull rod 706 is fixedly connected to the surface of the frame 2, and a protective cover 707 is fixedly connected to the lower end of the pull rod 706. The protective cover 707 is rotatably connected to the rotating shaft 3, and the gear 704 is located in the protective cover 707. The protective cover 707 can shield the rack 703 and the gear 704 to prevent foreign matter from being stuck between the gear 704 and the rack 703, affecting the normal operation of the gear 704 and the rack 703.

[0031] like Figure 3-Figure 5 As shown, the side wall of the protective cover 707 is fixedly connected with a brush plate 709, and the brush plate 709 is against the surface of the rack 703. The brush plate 709 will clean the teeth of the rack 703, so that the rack 703 and the gear 704 can mesh normally. The inner wall of the protective cover 707 is rotatably connected with a pressure roller 710, and the pressure roller 710 is slidably connected with the rack 703. The pressure roller 710 can limit the movement path of the rack 703, so that the rack 703 can stably contact with the gear 704.

[0032] The overall working principle is that the mounting frame 1 is used for docking and installation with the sprayer. When the rotating arm 4 needs to be unfolded, the output end of the electric push rod 701 is controlled to extend by means of the controller 6. The transmission plate follows the movement of the output end of the electric push rod 701 to drive the rack 703 to move. The movement of the rack 703 drives the gear 704 to rotate. The rotation of the gear 704 drives the rotating arm 4 to rotate, thereby achieving the purpose of unfolding the rotating arm 4 with one-button operation, thereby reducing the work intensity of the operator and facilitating the use of the sprayer for spraying. The rotating arm 4 rotates and contacts with the buffer sleeve 708. The buffer sleeve 708 made of rubber can reduce the collision force between the rotating arm 4 and the baffle rod 712. The baffle rod 712 has the effect of limiting the rotation range of the rotating arm 4. In this process, the folding tube 705 follows the movement of the connecting plate 702 and extends, thereby preventing foreign matter from adhering to the output end of the electric push rod 701. , affecting the normal operation of the electric push rod 701. The rack 703 will move along the arc surface of the pressure roller 710 during the movement. The pressure roller 710 can limit the movement path of the rack 703, so that the rack 703 can stably contact with the gear 704. The protective cover 707 can shield the rack 703 and the gear 704 to prevent foreign matter from being stuck between the gear 704 and the rack 703, affecting the gear 704 and the normal operation of the rack 703. When it is necessary to retract the rotating arm 4, the controller 6 is used to control the output end of the electric push rod 701 to retract. At this time, the gear 704 will rotate in the opposite direction, and the rotating shaft 3 will follow the rotation of the gear 704 to retract the rotating arm 4. During this process, the rack 703 will slide into the protective cover 707, and the brush plate 709 will clean the teeth of the rack 703, so that the rack 703 and the gear 704 can mesh normally.
