A specific application of this embodiment is as follows: the leftover material of wood processing is put into the feeding funnel 2, and the leftover material enters the screening and crushing box 1 along with the feeding funnel 2;

It first falls on the first deflector 4, and flows to the lower left with the first deflector 4. During the flow of the scrap material, it hits the dust-proof baffle 6, and the dust-proof baffle 6 rotates and opens about the hinge point without blocking it. The flow of leftover material; the leftover material continues to flow, hits the left side wall of the screening and crushing box 1, and continues to flow downward to the right along with the second deflector 5 in the reverse direction, continues to knock open the dust baffle 6, and enters the inlet at the top of the communication pipe 701. material through hole;

The motor 703 is started, the output shaft drives the gear to rotate, the gear drives the rotating screening tube 702 meshed with it to rotate, the leftover material entering the communication tube 701 flows into the rotary screening tube 702, and continues to flow downward to the left along with the inclined rotary screening tube 702 , During the flow process, the rotating screening tube 702 drives the leftover material to turn up and down, which can achieve a better screening effect, and the flow speed of the leftover material can also be controlled by controlling the inclination of the rotating screening tube 702, so as to control the leftover material in the rotating screening tube 702. within the screening time to obtain a suitable screening effect;

After screening, the recyclable large scraps flow into the scrap recycling box 10 along the communication pipe 701 for recycling, and the small and irregular scraps are screened out through the screening holes and fall into the crushing roller 8 for crushing, and crushed into The wood chips of a uniform size are dropped into the wood chip recovery box 9, which is convenient for recycling.

By arranging the first deflector 4 and the second deflector 5 in the present invention, the scraps can gradually flow downward along with the first deflector 4 and the second deflector 5, thereby further reducing the dumping and screening of the scraps. Dust escapes during the process, and a dust-proof baffle 6 is set on the first deflector 4 and the second deflector 5, and the dust-proof baffle 6 will not affect the entry of the leftover material when it flows. The dust-proof baffle 6 will remain in a vertical state under the action of gravity, which can further block the escape of dust and has a good dust-proof effect; by setting a rotatable rotating screening tube 702, the leftover material can be screened more fully The large corners that can be directly recycled are screened out into the scrap recycling box 10, and the small scraps that cannot be directly recycled directly enter the crushing roller 8, and are crushed into wood chips for recycling, which avoids the need for separate screening and removal. The tedious operation of crushing is performed again.

It is worth noting that the motor 703 is controlled by the control button. Since the equipment matched with the control button is a common equipment and belongs to the existing mature technology, its electrical connection relationship and specific circuit structure will not be repeated here.
