The bounce separation screen is equipment for separating materials according to different shapes and specific gravities of the materials to be separated. The material to be screened falls onto the screen surface through the feeding port, the bounce separation screen drives the screen plate to move up and down and back and forth through the crankshaft transmission part, and the screen material on the screen surface is shaken and dispersed and separated into three parts. Discharging the heavy and rolling 3D material part comprising bottles, stones, wood blocks or metals and the like from a three D material discharge port at a discharge end; a light, flat 2D material portion comprising plastic, film, paper, cardboard or fabric, etc.; the undersize material portion, including the fine material, sand or food residue, is discharged from a fine material discharge opening below the screen surface. The longitudinal and transverse toothed plates above the sieve plate can effectively prevent the 2D material from moving up and down on the sieve surface, and a blower can blow the 2D material back to the feeding end to discharge the 2D material from a discharge port below the feeding end. According to the property of the material to be screened, the inclination angle of the screen surface can be adjusted through the hinge shaft, the hydraulic cylinder and the angle adjusting frame, so that the optimal screening effect is achieved.

The beneficial effects of the utility model are that, only two kinds of materials are sieved and undersize after traditional equipment screening, and three kinds of materials can be separated to the spring screening machine, and the material classification more refines, and the follow-up technology of being convenient for is handled. Greatly improving the garbage disposal capability, the sorting efficiency and the automation degree. The equipment is lighter in weight, flexible, convenient and fast, low in cost and space-saving. Is an ideal separating sieve for treating and separating household garbage, pressed kitchen garbage, paper recovery and other industries. The modularized design, spare part interchangeability is good, convenient maintenance. The method has the characteristics of high screening efficiency, large treatment capacity and good garbage sorting effect. Can be used for screening various urban buildings, living and kitchen waste in a waste treatment plant.
