Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic cutting machines, in particular to a scrap steel cutting machine. Background Art

[0002] The scrap steel cutting machine is also called a scrap steel shearing machine or a cutter. It usually relies on hydraulic pressure to drive the groove gate to contact the gate platform, so as to cut the steel with a large shear force. In actual use, the inventor found that due to the continuous operation of the cutting machine, the cut steel will fall to the front area of ​​the gate. As the steel accumulates, it will gradually block the subsequent discharge of steel. If the accumulated steel is manually moved, the high-pile steel is easy to fall over and injure the workers, which poses a certain safety risk. Usually, the machine needs to be shut down and the steel needs to be pushed away by a forklift or shovel. In combination with the above viewpoints, people in this field have proposed a scrap steel cutting machine that can solve the above problems. Utility Model Content
