The movement of the movable sleeve 815 drives the elastic push plate 817 to move forward and backward. When the elastic push plate 817 moves forward and backward, the wood can be dispersed to avoid the wood from accumulating on the top of the screen plate 9. Since the wood falls between the two crushing rollers 5, it is easy to accumulate at the bottom between the two crushing rollers 5, that is, the top of the screen plate 9, for a long time. The elastic push plate 817 can disperse the wood. At the same time, when the elastic push plate 817 is moving, the third fixed rod 821 on the back of the second sliding sleeve 820 moves up and down repeatedly under the action of the wave groove 822, thereby driving one end of the elastic push plate 817 to move up and down, so as to avoid the accumulation of wood on the elastic push plate 817, thereby avoiding affecting the screening efficiency of the wood. The wood that meets the screening requirements is discharged through the discharge port at the bottom, and the wood that does not meet the screening requirements slides out of the screen plate 9 and is crushed again by another crushing roller.

[0037] The present invention provides a device for recycling waste wood. There are many methods and ways to implement the technical solution. The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be considered as the protection scope of the present invention. All components not specified in this embodiment can be implemented by existing technologies.
