[0024] In this embodiment, the inside bottom surface of the mounting groove 201 is provided with a movable groove 3, a movable plate 301 is slidably arranged in the inside of the movable groove 3, a spring 302 is fixed between the movable plate 301 and the movable groove 3, the top surface of the movable plate 301 is fixed with the bottom surface of the adsorption plate 202, one side of the adsorption plate 202 is fixed with a protruding block 303, the protruding block 303 penetrates through one side of the inner wall of the mounting groove 201, one side of the mounting seat 1 is fixed with a motor, the output end of the motor is fixed with a cam 304, the outer circular inner wall surface of the cam 304 is attached to one side of the protruding block 303, when the crushed waste falls on the adsorption plate 202, the workers start the motor, the motor drives the cam 304 to rotate, the protruding part of the cam 304 constantly pushes one side of the protruding block 303, when the protruding block 303 is pushed by the cam 304, the adsorption plate 202 is vibrated through the action of the spring 302, so that the crushed waste can quickly slide to the lower side of the inclined surface of the adsorption plate 202, while effectively reducing the hindering of the adsorbed reinforcing steel bars to the rolled waste, improving the separation efficiency and ensuring the smoothness of the crushing process.
[0025] In this embodiment, two guide rods 4 are fixed in the inside of the mounting groove 201, the two guide rods 4 are slidably inserted with one side of the adsorption plate 202, when the adsorption plate 202 vibrates under the action of the cam 304, the guide rods 4 guide the moving direction of the adsorption plate 202 and support the adsorption plate 202, thereby improving the stability of the device.

The protruding part of the cam 304 constantly pushes one side of the protruding block 303. When the protruding block 303 is pushed by the cam 304, it drives the adsorption plate 202 to vibrate through the action of the spring 302, so that the crushed waste can quickly slide to the lower side of the inclined surface of the adsorption plate 202, and effectively reduces the hindrance of the adsorbed steel bars to the falling waste. When the adsorption plate 202 vibrates under the action of the cam 304, the guide rod 4 guides the moving direction of the adsorption plate 202 and supports the adsorption plate 202, thereby improving the stability of the device. When the concrete waste is crushed by the counter-roller crusher 7 for the second time, the workers can take the crushed waste through the receiving hopper 5.
