The drum screen is a machine widely applied in the sorting technology, controls the sorting of garbage by controlling the particle size of particles, and has high sorting precision. The drum body of the drum screen is generally divided into a plurality of sections, the screen holes are arranged from small to large according to specific conditions, and the aperture of each section of screen hole is the same.

The commonly used drum screen mainly comprises a motor, a speed reducer, a drum device, a frame, a sealing cover and a feeding and discharging port.

The roller device is obliquely arranged on the frame. The motor is connected with the roller device through the speed reducer and the shaft coupling, and drives the roller device to rotate around the axis of the roller device. After the materials enter the roller device, the materials on the screen surface are overturned and rolled due to the inclination and rotation of the roller device, so that the qualified materials (undersize products) are discharged through a discharge hole at the bottom of the rear end of the roller, and the unqualified materials (oversize products) are discharged through a discharge hole at the tail part of the roller. Because the material is upset, the roll in the cylinder, make the material of card in the sieve mesh can be popped out, prevent that the sieve mesh from blockking up.

However, in the prior art, when the drum sieve is used for sorting garbage materials, due to the fact that the materials are wet and the number of strip-shaped materials is large, the phenomenon of hanging and blocking holes easily occurs on sieve holes (particularly coarse sieve holes of a coarse sieve plate) due to rotation. Great inconvenience is brought to the manual cleaning of the roller at regular time.
