[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. During the crushing process, the objects are fed from the feed channel into the crushing box for crushing, and then crushed into plastic particles. The plastic particles fall onto the first screen of the discharge box for screening. Unqualified plastic particles are guided by the first screen into the hose and the lifting cylinder, and then lifted up by the conveying screw, and then enter the feed channel through the secondary feed channel, and then crushed again by the crushing device in the crushing box, so as to ensure that the plastic particles are crushed to the qualified level and improve the crushing quality;

[0015] 2. In addition, a cross bar is provided on the conveying screw, and the cross bar rotates with the conveying screw. The cross bar can hit the flange of the discharge box, so that the discharge box vibrates, so that the first screen in the discharge box can perform efficient screening work; and because the discharge box is movably connected to the crushing box, the vibration of the discharge box will not have a significant impact on the crushing box, thereby not affecting the service life of the crushing device;

[0016] 3. The vibration of the discharge box does not require a vibration motor, so only one power mechanism is needed to drive the conveying screw to rotate and the discharge box to vibrate. No additional electric drive is required, which plays a role in high efficiency, energy saving and environmental protection. BRIEF DESCRIPTION OF THE DRAWINGS
