A second discharge port is provided above the screen 19, and the second discharge port is provided on the screening box 4. The second discharge port is connected to the return port 17 through the return mechanism.

[0030] The working principle of the utility model is as follows: when it is necessary to crush wood during actual production and use, the wood can be put into the box 8 through the first feed port, and then the wood is initially crushed in the coarse crushing mechanism, and then enters the fine crushing mechanism for further crushing, and the crushed wood particles fall onto the screen 19, and then the turning mechanism is operated to continuously turn the wood particles on the screen 19, and then the particles that meet the specifications are discharged from the outside of the device through the screen 19, and the particles that do not meet the specifications enter the return port 17 through the return mechanism, and then fall into the fine crushing mechanism for further crushing.

[0031] Furthermore, the flipping mechanism includes a first rotating drive member 14 , a first rotating shaft 13 and a raking assembly, wherein the lower portion of the first rotating shaft 13 is rotatably connected to the middle portion of the screen 19 , the upper portion of the first rotating shaft 13 is provided with the raking assembly, and the first rotating drive member 14 is drivingly connected to the first rotating shaft 13 .

[0033] From the above description, it can be seen that when the finely crushed wood particles fall into the upper part of the screen 19, the second rotating drive member 18 can be operated, so that the second rotating drive member 18 drives the rake member 11 to rotate through the second rotating shaft 12, so that the rake member 11 continuously rakes the wood particles, so that the particles that meet the specifications can better pass through the screen 19 and be discharged from the outside of the device. When it is necessary to turn over the wood particles on the screen 19 more comprehensively, the first rotating drive member 14 can be operated, so that the first rotating drive member 14 drives the rake member 11 to do a circular motion through the first rotating shaft 13, so that all the wood particles on the screen 19 can be turned over, and when it is necessary to re-crush the wood particles that have not been eliminated from the device, the first rotating drive member 14 can also drive the rake member 11 to rake the wood particles to the second discharge port, so that the wood that needs to be crushed again can better enter the inside of the return mechanism.

[0034] Furthermore, the return material mechanism includes a conveying pipe 6, a third rotating driving member 7 and a spiral conveying rod 16. A third feed port is provided at the lower portion of the conveying pipe 6, and a third discharge port is provided at the upper portion of the conveying pipe 6.

[0036] Furthermore, it also includes a valve body 15, and the valve body 15 is arranged inside the third feed port.
