When foamed concrete is mixed in the construction waste, it is necessary to screen out the foamed concrete in the construction waste. The foamed concrete is usually screened out by screening equipment, and the existing screening equipment is a device for screening out the foamed concrete in the construction waste. The screening equipment is convenient for vibrating and screening out the foamed concrete during operation, and is convenient for flipping and toggling the foamed concrete in the construction waste to quickly drop and screen out the foamed concrete during the screening operation.
