[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a wood waste crushing device, such as... Figure 1 , Figure 2 and Figure 3 As shown, the crushing device includes a base plate 1, a first mounting frame 2 fixedly mounted on the base plate 1, and a pressing structure set on the first mounting frame 2 for pressing the crushed wood waste.

[0027] The clamping structure includes an electric push rod 10 fixedly mounted on the first mounting frame 2, a clamping plate 11 fixedly mounted on the movable end of the electric push rod 10, a clamping table 4 fixedly mounted on the base plate 1, a clamping frame 5 slidably mounted on the clamping table 4, a movable block 6 fixedly mounted on the clamping frame 5, and a threaded rod 7 rotatably mounted on the first mounting frame 2. The movable block 6 has a threaded groove inside that matches the threaded rod 7.

[0028] The clamping frame 5 and the clamping table 4 can be combined to form a clamping box. The wood waste crushed on the device is transported into this clamping box. When the electric push rod 10 is activated, the movable end of the electric push rod 10 pushes the clamping plate 11, causing the clamping plate 11 to move into the interior of the clamping box, thereby compressing the wood waste inside the clamping box into blocks. The moving block 6 is screwed onto the threaded rod 7. The threaded rod 7 is set vertically. When the threaded rod 7 rotates, the thread engagement can force the moving block 6 to move vertically. The vertical movement of the moving block 6 can drive the clamping frame 5 connected to it to move, so that the crushed wood waste inside the clamping frame 5 can be pushed out by the clamping table 4 for workers to handle.

[0029] Furthermore, in order to improve the stability of the threaded rod 7 during rotation, such as Figure 1 , Figure 2 and Figure 5 As shown, a limit block 9 is fixedly connected to one end of the threaded rod 7, and a first bevel gear 8 is fixedly connected to the other end of the threaded rod 7.

[0030] The threaded rod 7 is mounted on the first mounting bracket 2. The limiting blocks 9 and the first bevel gear 8 mounted at both ends of the threaded rod 7 are in contact with the first mounting bracket 2, which greatly improves the stability of the threaded rod 7 when it rotates.

[0031] Furthermore, in order to enable the threaded rod 7 to rotate, such as Figure 1 , Figure 2 and Figure 5 As shown, a first motor 12 is fixedly connected to the base plate 1, and a mounting block 15 is fixedly connected to the base plate 1. A transmission rod 14 is rotatably connected to the mounting block 15. One end of the transmission rod 14 passes through the mounting block 15 and is fixedly connected to the output end of the first motor 12. A second bevel gear 13 is sleeved on the transmission rod 14, and the second bevel gear 13 meshes with the first bevel gear 8.

[0032] After the first motor 12 is started, the first motor 12 can drive the transmission rod 14 connected to its output end to rotate. The transmission rod 14 is mounted on the mounting block 15, and the mounting block 15 provides a stable guarantee for the transmission rod 14 when it rotates. When the transmission rod 14 rotates, it can drive the second bevel gear 13. The rotating second bevel gear 13 can drive the first bevel gear 8 that meshes with it to rotate. The first bevel gear 8 is connected to the threaded rod 7, thereby realizing the rotation of the threaded rod 7.

[0033] In order to enable wood waste to be pulverized, such as Figure 1 , Figure 2 and Figure 4 As shown, a second mounting bracket 3 is fixedly connected to the base plate 1, and a crushing box 16 is fixedly connected to the second mounting bracket 3. A crushing roller 17 is rotatably connected inside the crushing box 16.

[0034] Both ends of the crushing roller 17 pass through the crushing box 16. A second motor 18 is fixedly connected to the crushing box 16. The output end of the second motor 18 is fixedly connected to one end of the crushing roller 17, and a transmission gear 19 is fixedly connected to the other end of the crushing roller 17.

[0035] A feed box 20 is fixedly connected to the crushing box 16. A guide plate 21 is fixedly connected inside the feed box 20. The inner cavity of the feed box 20 is connected to the inner cavity of the crushing box 16. A discharge hopper 22 is fixedly connected to the bottom of the crushing box 16. The inner cavity of the crushing box 16 is connected to the inner cavity of the discharge hopper 22.

[0036] The crushing chamber 16 has two crushing rollers 17 inside, each connected to a drive gear 19. The two drive gears 19 mesh with each other. When one crushing roller 17 rotates, it can drive the drive gear 19 connected to it to rotate. The currently rotating drive gear 19 can drive the other drive gear 19 to rotate, and the other rotating drive gear 19 can drive the other crushing roller 17 to rotate. The two crushing rollers 17 rotate in opposite directions, thus crushing the wood waste inside the crushing chamber 16. The crushing blades on the two crushing rollers 17 are cross-attached, which greatly improves the crushing effect and eliminates the need for secondary crushing.

[0037] The second motor 18 is configured to provide rotational power for the crushing roller 17. The output end of the second motor 18 is connected to only one crushing roller 17. After the second motor 18 is started, it can directly drive the crushing roller 17 connected to it to rotate. Under the mutual meshing action of the two transmission gears 19, the two crushing rollers 17 can rotate together.

[0038] The feed box 20 is connected to the crushing box 16. After the wood waste is placed in the feed box 20, it can automatically slide into the crushing box 16 under the action of gravity. Two guide plates 21 are symmetrically installed in the feed box 20. The guide plates 21 can guide the wood waste to the middle of the two crushing rollers 17 when it is fed, so that the crushing rollers 17 can crush it.

[0039] The wood waste shredded in the shredder 16 can fall into the discharge hopper 22 at the bottom of the shredder 16 under the action of gravity. The discharge hopper 22 is set at an angle, and the end of the discharge hopper 22 rests on the clamping frame 5, which can transport the wood scraps into the clamping box, providing convenience for subsequent clamping work.
