Shredder and screen dismounting and mounting auxiliary mechanism for shredder

Abstract

The invention discloses a shredder and a screen dismounting and mounting auxiliary mechanism for the shredder. The shredder comprises a rack, a shredding chamber, a shredding assembly and a screen. The auxiliary mechanism comprises a rotating shaft rotationally arranged on the rack, a drive module used for driving the rotating shaft to rotate, a sling with one end connected with the rotating shaft, and a hoisting hole formed in the rack and located above one side of the screen. The sling penetrates through the hoisting hole and then is supported at the bottom of the screen, and the other end of the sling is connected to the portion, on the other side of the screen, of the rack. According to the auxiliary mechanism, through arrangement of the rotating shaft and the sling, when the screen is dismounted and mounted, the rotating shaft can be used for winding and unwinding the sling to achieve ascending and descending of the screen, meanwhile, when the rotating shaft stops rotating, the sling can pull the screen, and the screen is fixed. Accordingly, extra operators do not need to lift the screen any more, the labor cost is greatly saved, and potential safety hazards are avoided. According to the shredder provided with the auxiliary mechanism, dismounting and mounting of the screen are more facilitated.

Description

technical field [0001] The invention relates to a screen disassembly and assembly auxiliary mechanism for a shredder and a shredder. Background technique [0002] A shredder is a machine used for fine crushing, which is generally used to process unprocessed raw materials or scraps to make them smaller in size. A screen is usually installed at the bottom of the shredder to screen the material and avoid the output of large pieces of material that have not been shredded. After long-term use of the shredder, the screen at the bottom will inevitably be blocked due to material residues, which will affect the output efficiency of the material. At this time, the screen needs to be removed, cleaned and reinstalled; at the same time, the shredding accuracy is not high. However, the existence of the screen will affect the output efficiency of the material. At this time, the screen needs to be removed to ensure the output of the material. [0003] In the prior art, the screen mesh is ...

AI Technical Summary

Problems solved by technology

However, due to the heavy screen, at least two operators are required to lift the screen when disassembling the screen, and another operator completes the installation or disassembly of the screen and the shredder

In this way, not only the labor cost is greatly increased, but also the disassembly and assembly efficiency is low. At the same time, the heavy screen is lifted manually, which poses a great safety hazard
