Description
Technical Field
[0001] The utility model relates to the field of scrap steel recycling and relates to a scrap steel shearing device. Background Art
[0002] A device that processes industrial waste such as scrap steel and cuts larger scrap steel into smaller pieces, so as to facilitate the later cleaning and packaging of the scrap steel. The shearing crusher mainly relies on the principle of "shearing and cutting" to complete the process of crushing solid waste. The motor drives the reducer to transmit the torque to the movable knife of the crusher through the knife roller shaft. The knife hook of the movable knife hooks the material and tears it down, and the blades of the rollers cut the solid waste like scissors. The shearing crusher will slip when shearing and crushing cylindrical scrap steel, causing the cylindrical material to rotate between the two knife rollers, and the shearing and crushing operation of the cylindrical scrap steel material cannot be completed. At this time, manual assistance is required to flatten the cylindrical material, and then the shearing and crushing operation is performed, which leads to reduced production efficiency and increased labor costs.
