Technical Field

[0001] The utility model relates to the technical field of drum screens, and in particular to a drum screen with a cleaning function. Background Art

[0002] The drum screen is a widely used machine in sorting technology. It controls the garbage sorting by the particle size, and has high sorting accuracy. The drum screen is generally divided into several sections, depending on the specific situation. The screen holes are arranged from small to large, and the screen holes on each section have the same aperture.

[0003] Known Chinese publicly authorized patent: (publication number: CN202321577377.4) discloses a drum screen, including a frame, a first rotating shaft is rotatably installed inside the frame through a bearing, a drum screen is fixed to the outer wall of the first rotating shaft, a motor is fixed to the end of the first rotating shaft, and a unloading mechanism is installed on the discharge port. The drum screen rotates a handle, and then the handle drives the third rotating shaft to rotate, and then the third rotating shaft drives the two second bevel gears to rotate, and at the same time, the two second bevel gears drive the two first bevel gears and the two second rotating shafts to rotate simultaneously. Since the two second rotating shafts and the two screw rods are all threadedly connected, the two screw rods, the movable plate and the baffle move downward at the same time, so that the discharge port and the baffle are separated, thereby facilitating the discharge of the material inside the drum screen. Since the baffle is designed as an isosceles triangle structure, the material falling on the top of the baffle will not stay on the baffle, but will be discharged from both sides of the baffle, avoiding material residue.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned drum screen has the following problems: in the prior art, it is difficult to clean the drum screen during use. Once the screen mesh is blocked by impurities, the screening effect is easily affected. It is also difficult to clean the drum screen while it is working. For example, the screen holes are blocked by materials, which causes some of the screen holes on the drum to fail to play the due screening role, thereby causing the screening effect to deteriorate. Therefore, a drum screen with a cleaning function is proposed. Utility Model Content
