Figure 8 As shown, the output end of the driving motor 401 is also fixedly connected to a pulley 408, and a transmission belt 2 404 is sleeved on the pulley 408 and the pulley 3 405.

[0026] like Figure 1 , Figure 2 As shown, the compression mechanism 5 includes a hydraulic cylinder 501, which is fixedly connected to the compression bin 6. The output end of the hydraulic cylinder 501 passes through the compression bin 6 and extends to the end inside the compression bin 6 and is fixedly connected to a pressure plate 502. The lower side of the compression bin 6 is rotatably connected to the bin bottom plate 9 through a rotating shaft, and the lower side of the compression bin 6 is fixedly connected to a base 8.

[0027] like Fig. 9 As shown, the hook mechanism 10 includes a locking block 1005, which is fixedly connected to the bottom plate 9 of the silo, a pull ring 1004 is sleeved on the outer side of the locking block 1005, the upper part of the pull ring 1004 is rotatably connected to a pull plate 1002 via a rotating shaft, an unlocking handle 1001 is fixedly connected to the outer side of the end of the pull plate 1002 away from the pull ring 1004, the middle part of the pull plate 1002 is rotatably connected to two support plates 1003 via a rotating shaft, and the support plate 1003 is fixedly connected to the compression bin 6.

[0028] When the device is started, the wood processing waste material is placed on the reciprocating screening mechanism 1, the reciprocating screening mechanism 1 screens the wood chips and sawdust and leaks them into the guide bin 11, the guide bin 11 transports the wood chips and sawdust to the feed bin 7, the feed bin 7 transports the wood chips and sawdust to the compression bin 6 through the screening feed port 701, the reciprocating screening mechanism 1 transports the screened large wood blocks to the crushing bin 12, the crushing mechanism 3 in the crushing bin 12 crushes the large wood blocks and transports them to the compression bin 6 through the crushing feed port 306, the compression mechanism 5 compresses the wood processing waste material into shape in the compression bin 6, during the compression process, the bin blocking mechanism 2 closes the crushing feed port 306 and the screening feed port 701 to prevent the wood processing waste material from continuously entering the compression bin 6 during the compression process, after the wood processing waste material is compressed and formed, the hook mechanism 10 is opened, the bin bottom plate 9 is lowered, and the compressed and formed wood processing waste material is taken out and placed in a designated position.

[0029] After the wood processing waste material is placed on the reciprocating screening mechanism 1, the driving mechanism 4 is started, and the output end of the driving motor 401 starts to rotate. The driving motor 401 rotates to drive the pulley four 408 to rotate. Under the action of the transmission belt two 404, the pulley four 408 rotates to drive the pulley three 405 to rotate. The pulley three 405 rotates to drive the cam 406 to rotate. The cam 406 contacts the driven column 105. The rotation of the cam 406 pushes the driven column 105 to move forward. The driven column 105 moves forward and drives the screen plate 103 to move forward. The screen plate 103 moves forward. The forward movement drives the reciprocating column 104 to move forward, and the reciprocating column 104 moves forward to compress the reciprocating spring 102. After the cam 406 is out of contact with the driven column 105, the reciprocating spring 102 releases the pressure to push the reciprocating column 104 to move backward. The backward movement of the reciprocating column 104 pushes the screen plate 103 to move backward, and the backward movement of the screen plate 103 drives the driven column 105 to move backward. In this way, the reciprocating movement is circulated. The screen plate 103 screens the wood processing waste materials in the reciprocating movement, leaks the small wood blocks and sawdust, and transports the large wood blocks to the crushing bin 12.

[0030] When the crushing mechanism 3 in the crushing bin 12 crushes the large wood blocks, the driving motor 401 rotates to drive the pulley 1 402 to rotate. Under the action of the transmission belt 1 403, the pulley 1 402 rotates to drive the pulley 2 304 to rotate. The pulley 2 304 rotates to drive the driving gear 303 to rotate clockwise. The driving gear 303 is meshed and connected with the driven gear 302. The driving gear 303 rotates to drive the driven gear 302 to rotate counterclockwise. The driving gear 303 and the driven gear 302 rotate to drive the rolling shaft 301 to rotate in opposite directions. The rolling shaft 301 rotates to drive the crushing leaves 305 to rotate in opposite directions. The crushing leaves 305 rotate in opposite directions to crush the large wood blocks. After crushing, they are transported to the compression bin 6 through the crushing feed port 306.

[0031] When the wood processing waste materials need to be compressed and formed, the hydraulic cylinder 501 is started, and the output end of the hydraulic cylinder 501 drives the pressure plate 502 to move downward. The pressure plate 502 moves downward to compress the wood processing waste materials into shape. After the wood processing waste materials are compressed and formed, the output end of the hydraulic cylinder 501 drives the pressure plate 502 to move upward.

[0032] When the pressure plate 502 moves downward, it drives the baffle plate 201 to move downward. When the baffle plate 201 moves downward to a certain position, the inclined surface of the trigger column 210 contacts the inclined surface of the elastic pin 208. The trigger column 210 pushes the elastic pin 208 into the baffle plate 201, and the elastic pin 208 is out of contact with the pressure plate 502. At this time, the baffle plate 201 abuts against the lower side surfaces of the crushing feed port 306 and the screening feed port 701, thereby blocking the crushing feed port 306 and the screening feed port 701. When the pressure plate 502 continues to move downward, the locking pin 203 is pushed into the baffle plate 201 by the pressure plate 502 and compresses the return spring 204, and the locking pin 203 moves backward to push The locking column 212 moves backward, and the locking column 212 moves backward through the locking hole 211 to push the check column 205 to move backward. The locking column 212 has the same diameter as the end of the check column 205. The check column 205 moves backward to compress the ejection spring 207. Under the action of the inclined surface between the rectangular long groove and the square short groove on the fixing sleeve 206, the check column 205 rotates, and the square block on the check column 205 enters the rectangular long groove. The ejection spring 207 releases the pressure to push the check column 205 out. The check column 205 pops out a longer distance and is inserted into the locking hole 211, fixing the baffle plate 201 at the specified position to prevent wood processing waste from continuing to enter the compression bin 6 during the compression process.

[0033] When the silo blocking mechanism 2 needs to open the crushing feed port 306 and the screening feed port 701, the pressure plate 502 moves upward, and the pressure plate 502 pushes the locking pin 203 into the baffle plate 201 again to compress the return spring 204, and the locking pin 203 moves backward through the locking hole 211 to push the check post 205 to move backward, and the return spring 204 releases the pressure to push the locking pin 203 out, and the locking pin 203 moves backward to push the locking post 212 to move backward, and the locking post 212 moves backward through the locking hole 211 to push the check post 205 to move backward, and the diameter of the locking post 212 and the end of the check post 205 is Similarly, the check column 205 moves backward to compress the ejection spring 207, and the check column 205 rotates under the action of the inclined surface between the square long groove and the square short groove on the fixed sleeve 206, and the square block on the check column 205 enters the square short groove, and the ejection spring 207 releases the pressure to push the check column 205 out. The pop-up distance of the check column 205 becomes shorter and the baffle plate 201 is unlocked, and the pressure plate 502 continues to move upward and contacts with the partition 202, and the pressure plate 502 pushes the partition 202 to move upward, and the upward movement of the partition 202 drives the baffle plate 201 to move upward, so that wood processing waste materials can continue to enter the pressure bin.

[0034] When the compressed wood processing waste materials need to be taken out, the unlocking handle 1001 is pulled, and the unlocking handle 1001 moves outward to drive the upper part of the pull plate 1002 to move outward, and the lower part of the pull plate 1002 moves inward under the action of the middle rotating shaft, and the inward movement of the lower part of the pull plate 1002 pulls the upper part of the pull ring 1004 to move inward, and the upper part of the pull ring 1004 moves inward and breaks contact with the locking block 1005, and the silo bottom plate 9 moves downward under the action of gravity, and the downward movement of the silo bottom plate 9 slides out the compressed wood processing waste materials, and the compressed wood processing waste materials are placed in the designated position, the silo bottom plate 9 is lifted upward, and the pull ring 1004 is buckled on the outside of the locking block 1005, pushing the unlocking handle 1001 to move inward, and the unlocking handle 1001 moves inward to lock the silo bottom plate 9, and the wood processing waste materials are compressed in this cycle.

[0035] Before taking out the wood processing waste materials, the driving mechanism 4 is shut down, the pressure plate 502 is stopped at the lower position, and the silo blocking mechanism 2 continues to close the crushing feed port 306 and the screening feed port 701 to prevent wood processing waste materials from entering the compression bin 6 when the compressed wood processing waste materials are taken out.

It should be pointed out that, for a person skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
