Description

Technical Field

[0001] The invention relates to the field of shredding, in particular to a shredder. Background Art

[0002] A shredder is a machine used for coarse or fine crushing, mainly used to process unprocessed raw materials or scraps to make them smaller in size. This equipment is widely used in the recycling industry, such as waste treatment in the fields of plastics, metals, wood, rubber, textiles, etc. The shredder can crush and grind for easy storage and treatment. Waste plastics are crushed and recycled and converted into reusable raw materials. Waste wood, branches, etc. are crushed and crushed for the production of wood chip boards, artificial boards, etc. Scrap metals are crushed and crushed for metal recovery and reuse. The energy consumption of the shredder is relatively low, and it can handle various types of materials to meet the needs of different industries. The shredder is widely used in production and life, especially in the treatment, reuse and recycling of waste. It plays an important role. With people's attention to environmental protection and sustainable development, the application scope of the shredder will become more and more extensive, and will play a greater role in future development.

The shredding effect of the single-shaft shredder is very weak, which reduces the practicality and flexibility, reduces the overall work efficiency, and has low mixing efficiency, which is not conducive to material shredding processing. In addition, the lack of a reducer on the single-shaft shredder will cause accelerated wear of parts and increase maintenance costs. Summary of the invention

By reducing the speed, the reducer can reduce the wear of the motor and the connected equipment and extend the service life. The coupling ensures that the driving shaft and the driven shaft can rotate synchronously and transmit the operation smoothly. The coupling drives the first shaft to start rotating, and then the first shaft drives the first roller to start rotating. At this time, the first roller and the second roller begin to squeeze each other and tear the material into pieces. The shell arranged on the second pulley can prevent dust from falling on it and play a protective role. The observation plate arranged on the hollow box can be used to observe the internal situation of the machine during the processing. The shredded materials enter the recycling bin, and then the handle on the recycling bin can be used to take them out after the machine stops running, which is conducive to long-term work. This structure is easy to use, improves work efficiency, is convenient to operate, saves manpower, improves processing efficiency, and enhances flexibility. BRIEF DESCRIPTION OF THE DRAWINGS
