[0010] In one embodiment, in order to drive the transmission plate to reciprocate, the driving assembly includes a driving groove, a motor fixed in the driving groove, and a transmission wheel connected to the output end of the motor. The outer wall of the transmission wheel is provided with a protrusion, which will intermittently contact the transmission plate during rotation. A return spring is provided between the transmission plate and the inner wall of the driving groove.

[0011] Specifically, the motor is a servo motor with a worm gear reducer to prevent the transmission wheel from rotating too fast.

[0012] In one embodiment, the drive groove is connected to the sliding groove for positioning the transmission plate.

[0013] In one embodiment, in order to perform multi-stage vibration, the top edge of the screen frame is provided with a support frame that is fixedly connected to the outer wall of the guide hopper, and the rear end of the screen frame is provided with a vibration motor that outputs vibration force to the multi-stage screening structure.

[0014] In one embodiment, to improve the efficiency of separating feed, the separating block includes a screw threadedly connected to a sliding plate, and a U-shaped part is provided at the end of the screw away from the sliding plate.

[0015] In one embodiment, to facilitate disassembly and maintenance, the end face of the sliding plate is provided with an internal thread groove corresponding to the screw.

[0016] The advantages or beneficial effects of the above technical solutions include at least the following:

[0017] This utility model discloses a multi-stage vibrating sieving feed impurity sorting device. The feed hopper is equipped with a pre-treatment structure to separate adhering feed, preventing it from interfering with the sorting operation of the lower screen frame. During operation, the feed is introduced into the feed hopper. When it enters the discharge port, the motor drives the transmission wheel to rotate. The protrusions on the transmission wheel intermittently act on the transmission plate during rotation, causing the transmission plate, with the assistance of a return spring, to move the sliding plate back and forth towards the discharge port. The separating blocks on the sliding plate further separate the feed. The feed then enters the screen frame. The multi-stage sieving structure, in conjunction with the vibrating motor, performs multi-stage vibration sorting. Impurities fall into the impurity recovery box, and the clean feed is discharged from the feed outlet at the lower part of the screen frame. Attached Figure Description
