Environment-friendly numerical control plate shearing machine

The invention discloses an environment-friendly numerical control plate shearing machine which can solve the problem that the conventional numerical control plate shearing machine is complicated in structure, has no excess material collecting function, and causes noise pollution. The environment-friendly numerical control plate shearing machine includes a machine body the bottom of which is provided with a base, a vertical column which is fixed to the machine body and is provided with a slide groove and a material falling opening, a hydraulic driving mechanism which is fixed on the vertical column, a vertical compression rod which is connected to the hydraulic driving mechanism, a cutting device which is connected to the vertical compression rod and can move up and down in the slide groove, a multi-roll conveyor belt which is arranged at the material falling opening, a collecting tank which is arranged on the tail end of the multi-roll conveyor belt, and a silencer which is arranged in the collecting tank.
