[0050] The side wall of the dosing box 1104 is provided with a vibration mechanism for knocking and vibrating it, and the vibration mechanism includes a connecting plate 901 fixedly connected to the bottom of the sliding plate 304, and a second T-shaped guide rod 902 is inserted into the side wall of the connecting plate 901, one end of the second T-shaped guide rod 902 is fixedly connected to a ball 903, and the side wall of the second T-shaped guide rod 902 is sleeved with a third spring 904. When the sliding plate 304 moves back and forth, it can drive the connecting plate 901 to move back and forth, and then drive the ball 903 to move back and forth. When the ball 903 is against the side wall of the dosing box 1104, the third spring 904 is compressed. When the ball 903 moves away from the dosing box 1104, the ball 903 can move and reset under the action of the third spring 904. In this way, the ball 903 can knock and vibrate the side wall of the dosing box 1104 back and forth, thereby facilitating the feeding of powder medicine into the second hose 1119.

[0051] Working principle: When in use, during sewage treatment, the first moving module 1102 drives the U-shaped plate 1101 to move back and forth above the sewage treatment tank 1. When the trapezoidal plate 1106 moves to the top of the sewage treatment tank 1, under the action of gravity, the dosing box 1104 and the trapezoidal plate 1106 move downward, and the floating plate 1107 floats on the water surface. At this time, the powdered medicine in the dosing box 1104 can pass through the second hose 1119 and the first hose 1109 and then be sprinkled on the water surface through the dosing pipe 1110, thereby facilitating the control of the dosing height, so that the dosing pipe 111 0 is close to the water surface and is more evenly dispersed. At the same time, when the trapezoidal plate 1106 moves, it can drive the conical sleeve 204 to move. Under the action of gravity, the conical sleeve 204 sinks into the water, and the second telescopic tube 203 is stretched. When adding medicine, the water pump 205 is started. At this time, the sewage in the sewage treatment tank 1 can be sucked in through the second telescopic tube 203, and then sprayed out through the water spray pipe 1111 after passing through the U-shaped tube 202 and the annular tube 201, forming a water curtain, thereby preventing the powder medicine from escaping, ensuring the effect of automatic dosing, and at the same time, being healthier and more environmentally friendly;

[0052] When the sewage enters the fixed box 308, it will impact the surface of the rotary fan 310, causing the fixed box 308 and the rotating rod 309 to rotate. When the rotating rod 309 rotates, it can drive the cam 311 to rotate. When the tip of the cam 311 abuts against the side wall of the pushing block 307, it can drive the pushing rod 305 to slide along the inclined groove 312 through the L-shaped plate 306 and the sliding plate 304, thereby pushing the second movable plate 301 to move in the direction close to the moving rod 406. At the same time, the second spring 302 is stretched. When the tip of the cam 311 passes over the side wall of the pushing block 307, the second movable plate 301 can move and reset under the action of the second spring 302. This reciprocating process can make the second movable plate 301 and the sliding plate 304 reciprocate. At the same time, the mounting plate 1113 and the first inclined plate 1116 are driven to reciprocate by the pressure control mechanism, and the conveyor belt 1114 is driven to reciprocate by the conveying mechanism.

[0053] When the conveyor belt 1114 moves in the direction close to the moving rod 406, it can squeeze the powder medicine in the filter plate 1108. At the same time, by starting the second motor 1001 to rotate forward and reverse, it can drive the conveyor belt 1114 to rotate forward and reverse, so as to reciprocate and crush the powder medicine to prevent the powder medicine from solidifying. The crushed powder medicine can pass through the filter holes of the filter plate 1108 and fall to the bottom of the medicine adding box 1104 and flow out through the second hose 1119. When the powder falls completely, the conveyor belt 1114 can contact the side wall of the filter plate 1108, ensuring the effect of automatic medicine adding.

[0054] At the same time, when the conveyor belt 1114 contacts the side wall of the filter plate 1108, it can push the moving rod 406 to move, the first spring 410 is stretched, and at the same time, the disc 407 drives the pushing pin 409 to slide in the slide groove 408, so that the pointer 403 rotates clockwise along the first rotating shaft 402. At this time, the scale on the scale plate 404 indicated by the pointer 403 can be detected by the visual sensor 405. Moreover, when there are hard impurities in the powder medicine, the conveyor belt 1114 cannot contact the side wall of the filter plate 1108. At this time, the moving stroke of the moving rod 406 becomes The rotation angle of the pointer 403 becomes smaller, thereby facilitating the detection of hard impurities in the powder medicine. When hard impurities are found, the first motor 604 can be started. The rotation of the first motor 604 drives the rotation of the rotating block 603, and at the same time, drives the sealing plate 605 to rotate, thereby opening the discharge port 601. At the same time, the second motor 1001 is started to rotate forward. At this time, it can drive the conveyor belt 1114 to transport, and then the hard impurities can be transported to the discharge port 601 and fall into the collection box 606 for collection, thereby avoiding blockage of the automatic dosing mechanism and ensuring the effect of automatic dosing.

[0055] When the push block 307 moves back and forth, it can drive the third movable plate 703 to move back and forth through the movable frame 702, and then drive the dosing tube 1110 to move back and forth, so that the dosing is more evenly dispersed and the dosing effect is better.

[0056] When the conveyor belt 1114 squeezes the powdered medicine, the gravity plate 505 squeezes the hydraulic oil, thereby providing squeezing force to the conveyor belt 1114. When the conveyor belt 1114 hits the hard impurities, the sleeve rod 502 can slide into the sleeve 501, and the gravity plate 505 can be pushed upward along the working tube 504 by the action of the hydraulic oil, thereby facilitating the control of the maximum squeezing force of the conveyor belt 1114 on the powdered medicine, ensuring the crushing effect of the powdered medicine while facilitating the detection of hard impurities.

[0057] When dosing, the crushed powder medicine in the dosing box 1104 enters the second hose 1119. When automatic dosing is required, the second moving module 802 drives the first moving plate 801 and the second hose 1119 to move, so that the second hose 1119 overlaps with the first hose 1109. At this time, the powder medicine in the second hose 1119 can enter the first hose 1109 and the dosing tube 1110. When the speed of automatic dosing needs to be adjusted, the second moving module 802 drives the first moving plate 801 and the second hose 1119 to move, thereby adjusting the overlapping area of ​​the second hose 1119 and the first hose 1109, thereby adjusting the dosing speed. When dosing needs to be stopped, the second moving module 802 drives the first moving plate 801 and the second hose 1119 to move, so that the second hose 1119 is staggered with the first hose 1109. At this time, the first moving plate 801 is used to seal the second hose 1119.

[0058] Moreover, when the sliding plate 304 moves back and forth, it can drive the connecting plate 901 to move back and forth, and then drive the ball 903 to move back and forth. When the ball 903 is against the side wall of the dosing box 1104, the third spring 904 is compressed. When the ball 903 moves away from the dosing box 1104, the ball 903 can move and reset under the action of the third spring 904. In this way, the ball 903 can knock and vibrate the side wall of the dosing box 1104 back and forth, thereby facilitating the feeding of powder medicine into the second hose 1119.
