the inside of the box body (9b) is staggered and is abutted against the protrusions (93f) through the first screen (3) and the second screen (9h) which are hinged through the hinge (9j), so that the first screen (3) and the second screen (9h) are shaken, under the condition of no water flow, the motor (2) is connected with the second belt wheel (12) through the belt (92i) to realize rotation and sort plastics, the inner side wall of the box body (9b) is provided with a limiting plate (91k), the first screen (3) and the second screen (9h) are connected in the limiting plate (91k) in a sliding manner, a spring is arranged between the inner side wall of the box body (9b) and the first screen (3) and the second screen (9h), the first screen (3) and the second screen (9h) are reset, the distance between the two limiting plates (91k) is larger than the height of the first screen (3), the bump (93f) is prevented from being locked in the rotating process;

filtered plastics respectively fall into the first discharge port (9a) and the second discharge port (9g) to facilitate cleaning, a fan (92) is arranged on the side surface of the box body to separate dust in the crushed plastics, the secondary utilization rate of the plastics is improved, and an ash receiving box (4) is arranged on the other side surface of the box body (9b) corresponding to the fan to facilitate cleaning of the dust;

in order to avoid the problem that plastics with different sizes cannot be sorted, a crushing mechanism (8) is arranged at the top of a box body (9b) to facilitate primary crushing of the plastics, the plastics fall into a storage box (7) and are stirred by rotating a spiral piece (62), blockage is avoided, and a regulating gate plate (51) controls the flow rate of the plastics;

the fixing mechanism (9c) comprises a supporting column (91c), a fixing screw (92c) and a supporting block (93c), the bottom of the box body (9b) is fixedly connected with the supporting column (91c) in a rectangular structure, the bottom of the supporting column (91c) is fixedly connected with the supporting block (93c), and the surface of the supporting block (93c) is in threaded connection with the fixing screw (92 c);

this waste plastic letter sorting system cooperates with rabbling mechanism (6) through rubbing crusher structure (8), the plastics of having avoided not of uniform size cause the feed inlet to block up at the in-process of sorting, make plastics of not uniform size all can recycle again, a plurality of flabellums of surperficial equidistance fixed connection (9e) of erection column (93i), lay this system in rivers department and can drive erection column (93i) rotation, thereby drive second band pulley (12) and first band pulley (11) and rotate, the electric energy has been practiced thrift, side-mounting motor (2) of box (9b), this system can normally work when having avoided the water yield to be few, side-mounting fan (92) of box (9b), blow the inside that connects ash box (4) with the dust in the plastics after smashing difficult to the size, the utilization ratio of plastics has been increased, the deashing of being convenient for, the bottom of first screen cloth (3) and second screen cloth (9h) all with protruding (93f) of the surperficial conflict of transmission shaft (92f) When the transmission shaft (92f) rotates for a circle, the first screen (3) and the second screen (9h) shake, so that blanking is facilitated.
