A pair of racks 22 are symmetrically meshed and connected to the upper and lower sides of the gear 21. Connecting rods 20 are fixed to the ends of the racks 22. A slide is provided at the upper end of the gear box 19. The upper end of the connecting rod 20 extends out of the slide and is fixed to the baffle 17 on the same side. A handle 18 is fixed to the end of the baffle 17 away from each other. A spring 23 is fixed between the side of the connecting rod 20 and the inner wall of the gear box 19. When installing the spray gun 10, pull the handle 18 first, and the handle 18 drives the baffle 17 to slide The two baffles 17 then move in the opposite direction until they no longer block the notch of the T-slot 14. Then, the T-bar 15 under the mounting seat 9 is aligned with the T-slot 14 on the slide 8 and slides from left to right. After the T-bar 15 slides into the T-slot 14, the handle 18 can be released. At this time, the spring 23 is used to reset the connecting rod 20. At this time, the two baffles 17 block the notch of the T-slot 14 again to prevent the T-bar 15 from moving out of the T-slot 14, so that the spray gun 10 can be installed on the slide 8.

[0018] The lower part of the slide 8 is provided with a reciprocating translation mechanism, and the reciprocating translation mechanism includes a support 1, a linear guide rail 24, a guide rod 2, a threaded rod 3, a servo motor 4, a PLC controller 5, a slider 6 and a guide block 7.

The guide block 7 and the slider 6 are both fixed to the slide 8. When the threaded rod 3 rotates, as the threaded rod 3 and the slider 6 are threadedly engaged, the slider 6 drives the slide 8 to slide on the linear guide rail 24, and the slide 8 also drives the guide block 7 to slide along the guide rod 2. By making the slide 8 reciprocate left and right, the slide 8 drives the mounting seat 9 to move synchronously;

The PLC controller 5 is located on one side of the servo motor 4 and is installed on the support 1. The PLC controller 5 is connected to the servo motor 4 signal. The liquid inlet end of the spray gun 10 is connected to a connecting pipe 11, and the end of the connecting pipe 11 is connected to a solenoid valve 12. The other end of the solenoid valve 12 is connected to a hose 13. The PLC controller 5 is connected to the solenoid valve 12 signal. By timing the servo motor 4 and the solenoid valve 12 in the PLC controller 5, the end of the hose 13 is connected to a pump. In this way, the servo motor 4 drives the threaded rod 3 to rotate. As the threaded rod 3 and the slider 6 are threaded together, the slider 6 drives the slide 8 to slide on the linear guide rail 24. The slide 8 will also drive the guide block 7 to slide along the guide rod 2. By making the slide 8 reciprocate left and right, the slide 8 drives the mounting seat 9 to move synchronously, and the mounting seat 9 drives the spray gun 10 to move. The spray gun 10 can also spray liquid medicine. In this way, the PLC controller 5 controls the time, speed, acceleration and deceleration of the back and forth movement. One movement from left to right or right to left is counted as one time. The PLC controller 5 can complete it according to the set number of times and then enter the waiting time. Once the waiting time is up, it will move back and forth again. This cycle of adding medicine is repeated, and one spray gun 10 replaces multiple spray guns 10, reducing the unevenness and error caused by multiple spray guns 10, reducing the air supply and the flying of medicine mist when spraying by multiple spray guns 10, reducing the cost of spray gun 10, reducing the problem of many failures due to multiple spray guns 10, and the sprayed medicine mist is more uniform.

[0020] Working principle: When installing the spray gun 10, first pull the handle 18, and the handle 18 drives the baffle 17 to slide, so that the two baffles 17 move in the opposite direction until they no longer block the notch of the T-slot 14, and then align the T-bar 15 under the mounting seat 9 with the T-slot 14 on the slide 8 and slide it from left to right. After the T-bar 15 slides into the T-slot 14, the handle 18 can be released. At this time, the two baffles 17 block the notch of the T-slot 14 again to prevent the T-bar 15 from moving out of the T-slot 14, so that the spray gun 10 can be installed on the slide 8, and then the servo motor 4 and the solenoid valve 12 are started at a fixed time in the PLC controller 5, so that the servo motor 4 drives the threaded rod 3 rotates, and as the threaded rod 3 and the slider 6 are threadedly matched, the slider 6 drives the slide 8 to slide on the linear guide rail 24, and the slide 8 also drives the guide block 7 to slide along the guide rod 2. By making the slide 8 reciprocate left and right, the slide 8 drives the mounting seat 9 to move synchronously, and the mounting seat 9 drives the spray gun 10 to move, and the spray gun 10 can also spray liquid medicine. In this way, the PLC controller 5 controls the time, speed, acceleration and deceleration of the back and forth action. One time is counted from left to right or right to left. The PLC controller 5 can complete the process according to the set number of times and then enter the waiting time. When the waiting time is up, the back and forth action is repeated in this way to add medicine, so that the sprayed medicine mist is more uniform.
