[0043] Embodiment 1

[0044] Please combine Figures 1 to 11As shown, the present invention provides a wood product recycling and pulverizing device, which comprises a crushing box 10, a motor 12, a reducer 13 and a crushing roller 11; wherein, a pair of crushing rollers 11 and a motor 12 are provided, and the two crushing rollers 11 are rotatably installed inside the crushing box 10, and the output ends of the two motors 12 are fixedly connected to the reducer 13, and the reducer 13 is fixedly connected to the ends of the two crushing rollers 11, and the two crushing rollers 11 are relatively rotated under the action of the two motors 12, and crushing teeth 111 are fixedly installed at equal intervals in the length direction of each crushing roller 11, and a gap is formed between two adjacent crushing teeth 111, and the gaps on the two crushing rollers 11 are alternately distributed, and the crushing device also includes:

[0045] A first rotating rod 21, which is rotatably mounted inside the crushing box 10, and is located directly above one of the crushing rollers 11, and the first rotating rod 21 is connected to one of the crushing rollers 11 through a first transmission belt 26;

[0046] A first material receiving assembly is provided with a plurality of first material receiving assemblies, each of which is fixedly mounted on the outer surface of the first rotating rod 21. The first material receiving assembly is composed of a plurality of first rod groups and a plurality of first pressing wheels 22. The plurality of first rod groups are evenly spaced and distributed in the circumferential direction of the first rotating rod 21. A first pressing wheel 22 is rotatably mounted on one end of each first rod group, and a limiting ring 221 is fixedly mounted on each first pressing wheel 22;

[0047] A second rotating rod 31, which is rotatably mounted inside the crushing box 10 and is located directly above the other crushing roller 11. The second rotating rod 31 is connected to the other crushing roller 11 through a second transmission belt 37. As the two crushing rollers 11 rotate relative to each other, the first rotating rod 21 and the second rotating rod 31 also rotate relative to each other;

[0048] The second material receiving assembly is provided with a plurality of second material receiving assemblies, which are composed of a plurality of second rod groups and a plurality of second pressing wheels 32. The plurality of second rod groups are evenly spaced and distributed in the circumferential direction of the second rotating rod 31. Each second rod group is slidably connected to the second rotating rod 31. A third spring 36 is fixedly arranged between each second rod group and the second rotating rod 31. A second pressing wheel 32 is rotatably mounted on one end of each second rod group. Each second pressing wheel 32 is provided with an annular limiting groove 321 adapted to the limiting ring 221.

[0049] A storage frame 41 is fixedly installed on the top of the crushing box 10 through a mounting plate 411. The interior of the storage frame 41 is used to store waste wood products to be crushed. A discharge channel 43 is provided on the bottom end of the crushing box 10. The wood products in the storage frame 41 are discharged through the discharge channel 43. A plurality of guide rails 46 are fixedly installed on the lower surface of the storage frame 41. The second rotating rod 31 will rotate synchronously with another crushing roller 11. When the second pressing wheel 32 rotates to fit the lower surface of the storage frame 41, the second pressing wheel 32 will be located on one side of the guide rail 46. Thereafter, the guide rail 46 will be squeezed with the second pressing wheel 32. After the second rod group is pushed, it will slide in the length direction of the second rotating rod 31, so that the second pressing wheel 32 and the second pressing wheel 32 are in contact with each other. The first pressing wheel 22 is located on the same plane. Before the second pressing wheel 32 is separated from the guide rail 46, the second pressing wheel 32 will fit with the first pressing wheel 22, so that the limiting ring 221 enters the annular limiting groove 321 on the second pressing wheel 32. At this time, even after the second pressing wheel 32 is separated from the guide rail 46, the second pressing wheel 32 will remain in contact with the first pressing wheel 22. At this time, the second pressing wheel 32 and the upper part of the first pressing wheel 22 form a space for storing wooden products. The wooden products in the storage frame 41 fall into the space through the discharge channel 43. The second pressing wheel 32 and the first pressing wheel 22 will continue to move downward. Since there is wooden products under the second pressing wheel 32 and the first pressing wheel 22, Some wood products are large in size and difficult to quickly enter the crushing area between the two crushing rollers 11. When the second pressure wheel 32 and the first pressure wheel 22 move downward, they will squeeze the wood products below them, so that the larger wood products can quickly enter the crushing area. Before the second pressure wheel 32 contacts the other crushing roller 11, the second pressure wheel 32 is separated from the first pressure wheel 22. At this time, the wood products located above the second pressure wheel 32 and the first pressure wheel 22 fall onto the two crushing rollers 11. At the same time, the second rod group is reset under the elastic force of the third spring 36, so that the second pressure wheel 32 is located in the interval of the other crushing roller 11. When the second pressure wheel 32 contacts the outer surface of the crushing roller 11, it contacts the second pressure wheel 32. The second rod group connected to the second pressure wheel 32 has a limiting effect on the movement of the wood products, so that the wood products can enter the crushing area faster. For the above process, the crushing equipment can automatically and uniformly take materials and transport a fixed amount of wood products to the crushing area. The staff only needs to concentrate the wood products and place them inside the storage frame 41, avoiding the need for staff to continuously add wood products to the crushing equipment. In addition, the second pressure wheel 32 and the first pressure wheel 22 can press down the wood products, so that the wood products can quickly enter the crushing area for crushing, especially some larger wood products, to prevent the wood products from constantly rolling on the crushing roller 11 and unable to enter the crushing area, which is beneficial to improving the crushing efficiency of the wood products.

[0050] Based on the first embodiment, the solution in the first embodiment is further detailed in combination with the following specific working method, as described below for details.

[0051] Embodiment 2

[0053] A pair of rotating plates 42 are rotatably installed on the bottom end of the storage frame 41, and the two rotating plates 42 are set to an inclined state. The discharge channel 43 is located at the bottom ends of the two rotating plates 42. A torsion spring 45 is fixedly installed between the two rotating plates 42 and the storage frame 41. The elastic force of the torsion spring 45 is greater than the elastic force of the plurality of second springs 35, and the elastic force of the torsion spring 45 is also greater than the elastic force of the plurality of first springs 25. When the second pressing wheel 32 and the first pressing wheel 22 are respectively pressed and contacted with the two rotating plates 42, the second spring 35 and the first spring 25 will contract first, and when the second movable rod 34 and the first movable rod 24 can no longer slide, the second pressing wheel 32 and the first pressing wheel 22 can push the rotating plate 4 2 rotates, wherein a plurality of guide rails 46 are fixedly installed on the rotating plate 42 located just above the second rotating rod 31, and the guide rails 46 include straight rails 461 and inclined rails 462 in the length direction, and a pair of straight rails 461 are provided, and the inclined rail 462 is provided between the two straight rails 461. When the second pressing wheel 32 contacts the lower surface of the rotating plate 42, the second pressing wheel 32 is first located on one side of the straight rail 461. During the continuous movement of the second pressing wheel 32, the second pressing wheel 32 will contact and squeeze with the inclined rail 462, so that the second outer cylinder 33 slides in the length direction of the second rotating rod 31. When the second pressing wheel 32 moves to the straight rail 461 close to the discharge channel 43, the second pressing wheel 32 is in contact with the first pressing wheel 32. The wheels 22 are in the same plane, and the second pressure wheel 32 will contact the first pressure wheel 22 before leaving the straight rail 461, so that the limiting ring 221 can smoothly enter the annular limiting groove 321, and a conical surface 322 is provided on the side surface of the second pressure wheel 32 close to the guide rail 46. When the second pressure wheel 32 contacts the rotating plate 42, the conical surface 322 can ensure that the second pressure wheel 32 is always located on one side of the guide rail 46; what needs to be explained in the above structure is that during the movement of the second pressure wheel 32 and the first pressure wheel 22 on the lower surface of the rotating plate 42, when the second spring 35 and the first spring 25 can no longer contract, the second pressure wheel 32 and the first pressure wheel 22 can respectively The two rotating plates 42 rotate upward, and after the two rotating plates 42 rotate, the discharge channel 43 can be closed to prevent the wooden products from falling further. When the second pressure wheel 32 and the first pressure wheel 22 are separated from the two rotating plates 42 respectively, the rotating plates 42 rotate downward quickly under the elastic force of the torsion spring 45. The downward rotation of the two rotating plates 42 will cause the wooden products in the storage frame 41 to shake, which can avoid the problem that the wooden products are stuck inside the storage frame 41 due to the accumulation of wooden products inside the storage frame 41, resulting in the wooden products cannot be discharged smoothly from the discharge channel 43; a limiting plate 44 is fixedly installed on the storage frame 41 and at one end of the rotating plate 42 to limit the downward rotation range of the rotating plate 42.

Any ordinary technician in the industry can smoothly implement the present invention as shown in the drawings and described above. However, any equivalent changes, modifications and evolutions made by technicians familiar with the profession without departing from the scope of the technical solution of the present invention using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention are still within the protection scope of the technical solution of the present invention.
