[0002] Construction waste refers to the slag, abandoned soil, silt, abandoned materials and other wastes generated during the construction, laying, demolition or repair of various buildings, structures, pipelines, etc. by construction units or individuals. When processing construction waste, vibrating screens are often needed to screen the crushed waste.

[0003] The existing vibrating screen for construction waste treatment is mainly composed of a screen box, a screen, a vibrator, a vibration-damping spring device, a base frame, etc. Its working principle is that the vibrator is driven by a motor to vibrate, causing the screen to start vibrating, and the construction waste materials move from the top to the bottom of the screen, and are affected by the vibration force on the screen, thereby separating into different particle sizes. Materials of different particle sizes will fall into different output ports to achieve the purpose of screening.
