[0024] The anti-accumulation mechanism 2 includes a feed box 201, a feed port 202, a chute 203, a slider 204, a connecting groove 205, a first screw 206, a nut 207, a baffle 208, a protective shell 209, a first motor 210, a first bearing 211, a worm 212, a second bearing 213, a ball nut seat 214, a worm gear 215, a second screw 216, an extrusion cylinder 217, a connecting plate 218, a limit block 219 and a limit groove 220. The feed box 201 is fixedly installed on the upper end of the crusher 1, a feed port 202 is provided on one side surface of the feed box 201, chute 203 is provided on both sides of the inner wall of the feed box 201, a slider 204 is provided inside the chute 203, a connecting groove 205 is provided on one side surface of the feed box 201, and the slider 2 A first screw 206 is welded on one side surface of 04, a nut 207 is provided at one end of the first screw 206, a baffle 208 is fixedly connected to one side surface of the slider 204, a protective shell 209 is fixedly installed on the upper side surface of the feed box 201, a first motor 210 is fixedly installed on one side surface of the protective shell 209, first bearings 211 are provided at both ends of the protective shell 209, a worm 212 is provided at one end of the first bearing 211, second bearings 213 are provided at both ends of the protective shell 209, a ball nut seat 214 is provided at one end of the second bearing 213, and a worm gear 215 is provided on the outer surface of the ball nut seat 214, through the feed box 201, the feed port 202, the slide groove 203, the slider 204, the connecting groove 205, the first screw 206, The nut 207, the baffle 208, the protective shell 209, the first motor 210, the first bearing 211, the worm 212, the second bearing 213, the ball nut seat 214 and the worm wheel 215 are arranged. When the crushing work is performed, the plastic parts are put into the material box 201 through the feed port 202. When the plastic parts are put in, the nut 207 is loosened and the baffle 208 is pulled. At this time, the slider 204 moves in the slide groove 203, and the first screw 206 moves in the connecting groove 205, so that the baffle 208 moves in and out of the material box 201, so that the plastic parts can fall downward into the crusher 1. After a certain amount of plastic parts are put in, the baffle 208 is moved into the material box 201. The baffle 208 can block the plastic parts in the feed box 201 to prevent the plastic parts from falling into the crusher 1. There are too many pieces of material, and the crushing speed cannot keep up, resulting in accumulation of materials. The baffle 208 can prevent the plastic pieces from splashing out during crushing. Secondly, the first motor 210 can be started during crushing. The first motor 210 rotates the worm 212, and the worm wheel 215 meshing with the worm 212 is also driven to rotate. At this time, the worm wheel 215 drives the ball nut seat 214 to rotate, and the second screw 216 inside the ball nut seat 214 will drive the extrusion cylinder 217 to move downward. The downward moving extrusion cylinder 217 can extrude larger plastic pieces downward, so that the efficiency of plastic piece crushing becomes higher, and the accumulation of materials is further prevented. When the extrusion cylinder 217 moves downward, the connecting plate 218 slides in the limiting groove 220 through the limiting block 219 to limit the extrusion cylinder 217.The extrusion cylinder 217 can move up and down in a straight line.

Through the setting of the extrusion cylinder 217, the extrusion cylinder 217 will extrude larger plastic parts when it moves up and down, thereby promoting the crushing of the plastic parts and preventing material accumulation.

[0026] Furthermore, the slider 204 forms a sliding structure with the feed box 201 through the slide groove 203, and one end of the first screw 206 passes through the connecting groove 205 and is threadedly connected to the nut 207. Through the setting of the slide groove 203 and the slider 204, the slider 204 slides in the slide groove 203, driving the baffle 208 to move in the feed box 201, so that the baffle 208 can block and intercept the plastic parts to prevent material accumulation.

[0027] Furthermore, the worm 212 is meshedly connected with the worm wheel 215, and the worm 212 forms a rotating structure with the protective shell 209 through the first bearing 211. Through the setting of the worm 212, when the worm 212 rotates, it can drive the worm wheel 215 to rotate together, and the worm wheel 215 can drive the ball nut seat 214 to rotate.

[0028] Furthermore, the ball nut seat 214 forms a rotating structure with the protective shell 209 through the second bearing 213. Through the setting of the ball nut seat 214, the ball nut seat 214 allows the second screw 216 to move up and down, and the second screw 216 will drive the extrusion cylinder 217 to extrude the larger plastic parts downward.

[0029] Furthermore, the limit block 219 forms a sliding structure with the feed box 201 through the limit groove 220. Through the setting of the limit block 219 and the limit groove 220, the limit block 219 slides in the limit groove 220, which can limit the movement of the extrusion cylinder 217.

[0030] Further, the crushing mechanism 3 includes a second motor 301, a third bearing 302, a first rotating rod 303, a first claw 304, a first gear 305, a crawler 306, a second gear 307, a second rotating rod 308 and a second claw 309.

Through the arrangement of the second motor 301, the third bearing 302, the first rotating rod 303, the first knife claw 304, the first gear 305, the crawler track 306, the second gear 307, the second rotating rod 308 and the second knife claw 309, when the crushing work is performed, the second motor 301 is started, the second motor 301 drives the first rotating rod 303 to rotate, the first gear 305 at one end of the first rotating rod 303 also rotates, and the first gear 305 drives the crawler track 306 to move when the first gear 305 rotates. At this time, the second gear 307 at the other end of the crawler track 306 is also driven to rotate synchronously with the first gear 305, so that the first rotating rod 303 and the second rotating rod 308 can simultaneously drive the first knife claw 304 and the second knife claw 309 to perform a rotational crushing movement, and the first knife claw 304 and the second knife claw 309 cooperate with each other in crushing, and the crushing effect is better.

[0031] Furthermore, a third bearing 302 is provided at one end of the first rotating rod 303 and the second rotating rod 308. The first rotating rod 303 forms a rotating structure with the crusher 1 through the third bearing 302. Through the setting of the third bearing 302, the first rotating rod 303 and the second rotating rod 308 can rotate at one end of the crusher 1 through the third bearing 302, thereby driving the first claw 304 and the second claw 309 to rotate.

[0032] Working principle: When crushing, put the plastic parts into the material box 201 through the feed port 202. When putting the plastic parts, loosen the nut 207 and pull the baffle 208. At this time, the slider 204 moves in the slide groove 203, and the first screw 206 moves in the connecting groove 205, so that the baffle 208 moves in and out of the material box 201, so that the plastic parts can fall down into the crusher 1. After a certain amount of plastic parts are put in, move the baffle 208 into the material box 201. The baffle 208 can block the plastic parts in In the feed box 201, too many plastic parts are prevented from falling into the crusher 1, and the crushing speed cannot keep up with the formation of material accumulation, and the baffle 208 can prevent the plastic parts from splashing out during crushing. Secondly, the first motor 210 can be started during crushing, and the first motor 210 rotates the worm 212, and the worm wheel 215 meshing with the worm 212 is also driven to rotate. At this time, the worm wheel 215 drives the ball nut seat 214 to rotate, and the second screw 216 inside the ball nut seat 214 will drive the extrusion cylinder 217 to The extrusion cylinder 217 moving downward can extrude a relatively large plastic part downward, and when the extrusion cylinder 217 moves downward, the connecting plate 218 slides in the limiting groove 220 through the limiting block 219 to limit the extrusion cylinder 217, and then the second motor 301 is started, and the second motor 301 drives the first rotating rod 303 to rotate, and the first gear 305 at one end of the first rotating rod 303 also rotates. When the first gear 305 rotates, it drives the crawler 306 to move. At this time, the second gear 305 at the other end of the crawler 306 307 is also driven to rotate synchronously with the first gear 305, so that the first rotating rod 303 and the second rotating rod 308 can simultaneously drive the first claw 304 and the second claw 309 to perform a rotating crushing motion. Secondly, when the crushing work is performed, the water pump 402 is started, and the water pump 402 pumps out the water in the water tank 401 through the suction pipe 403, and then the water pump 402 discharges the water flow into the sprinkler pipe 405 through the drain pipe 404, and then the water flow will be sprayed out in the form of mist through the atomizing nozzle 406.
