Description

Technical Field

[0001] This utility model relates to the field of wood shredders, and in particular to mobile wood shredders. Background Technology

[0002] A wood shredder is a mechanical device used to crush raw materials such as wood, branches, and leaves into smaller particles or powder.

[0003] When using the main body of the shredder to process wood, the wood is put into the feed hopper, and then the first motor on the moving frame is started to drive the chain to rotate, which in turn drives the sprocket crushing roller to rotate inside the shredder body to crush the put-in wood. The crushed wood chips are filtered through an internal filter screen and discharged from the discharge pipe. Because the crushed wood chips are irregular in shape and have different moisture content, they are easy to get stuck in the filter screen, causing blockage and hindering the passage of subsequent wood chips, thus reducing the working efficiency of the shredder body. At the same time, the filter screen on the main body of the traditional shredder body is generally of a fixed size. This means that when different fineness of chips needs to be crushed, the filter screen needs to be frequently disassembled and replaced, resulting in low adaptability and affecting the use of the shredder body. Utility Model Content

[0004] The technical problem this invention aims to solve is as follows: When using the main body of a crusher to crush wood, the wood is fed into the hopper, and then the first motor on the moving frame is started to drive the chain to rotate, which in turn drives the sprocket crushing roller to rotate inside the main body of the crusher to crush the wood. The crushed wood chips are filtered through an internal filter screen and discharged from the discharge pipe. However, due to their irregular shape and varying moisture content, the crushed wood chips are prone to getting stuck in the filter screen's pores, causing blockage and hindering the passage of subsequent wood chips, thus reducing the working efficiency of the main body of the crusher. At the same time, the pore size of the filter screen on the main body of a traditional crusher is generally fixed. This means that when different fineness of chips needs to be crushed, the filter screen needs to be frequently disassembled and replaced, resulting in low adaptability and affecting the use of the main body of the crusher.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a mobile wood crusher, including a mobile frame and a chain.

The inner walls of both ends of the chain are respectively sleeved on the outer surface of a sprocket rod and a sprocket crushing roller, which are installed at the output end of the first motor through a coupling. An anti-clogging device is set on the inner wall of the crusher body near the discharge pipe. The anti-clogging device can achieve the anti-clogging effect by tapping and vibrating the surface of the filter screen through a tapping mechanism. At the same time, the filter hole size on the filter screen can be adjusted by an adjustment mechanism to improve its adaptability. In addition, if clogging occurs when the size is small, the filter hole size can be enlarged to achieve the anti-clogging effect.

[0006] The aforementioned components achieve the following effects: When using the main body of the crusher to crush wood, the wood is fed into the hopper, and then the first motor on the moving frame is started to drive the chain to rotate, which in turn drives the sprocket crushing roller to rotate inside the main body of the crusher to crush the wood. The crushed wood chips are filtered through an internal filter screen and discharged from the discharge pipe. When in use, the filter screen can be protected against clogging by activating an anti-clogging device to prevent the crushed wood chips from blocking the filter screen, thereby improving the working efficiency of the main body of the crusher. At the same time, the adjustment mechanism in the protective device can be adjusted according to usage needs to improve the adaptability of the main body of the crusher and facilitate its use.

[0007] Preferably, the anti-clogging device includes a filter screen, wherein a mechanism for easy replacement is provided between the filter screen and the inner wall of the crusher body; an adjustment mechanism, wherein the adjustment mechanism is disposed in the inner wall of the filter screen for adjusting the size of the filter holes on the filter screen; and a tapping mechanism, wherein the tapping mechanism is disposed in the inner wall of the filter screen for tapping one side of the filter screen to cause it to vibrate and achieve the effect of preventing clogging.
