Grain processing drum screen with self-cleaning function

Abstract

The invention discloses a grain processing drum screen with a self-cleaning function, and relates to the technical field of screening devices. According to the grain processing drum screen with the self-cleaning function, through a cleaning assembly arranged between a screen drum and an outer shell, when a rotating shaft drives the screen drum to rotate through positioning frames at the two ends, the inner walls of screen holes can be cleaned through cooperation of a plurality of telescopic columns in the cleaning assembly and ejector rods sliding back and forth and the screen holes in the screen drum; meanwhile, through the ejector rods sliding back and forth, grains and the like clamped in the screening holes can be pushed, and the phenomenon of blocking in the screening holes is avoided; and through scraping plates arranged on the two sides of the interior of the outer shell, dust on the outer wall of the screen drum can be scraped away when the screen drum rotates, and the situation that the grain screening effect is affected due to dust accumulation is avoided; and thus, the screen drum can be cleaned while the screen holes of the equipment are prevented from being blocked, and the grain screening effect is improved.

Description

technical field [0001] The invention relates to the technical field of screening devices, in particular to a cylindrical screen for grain processing with self-cleaning function. Background technique [0002] The cylinder screen is usually used in the grain screening process. The working part of the cylinder screen is cylindrical, and the whole screen rotates around the axis of the cylinder. The axis is generally installed at a small inclination angle; One end feeds in, the fine-grade material passes through the sieve hole on the cylindrical working surface, and the coarse-grained material is discharged from the other end of the cylinder, and the grain is screened. [0003] Due to the different particle sizes of the grain, they often get stuck inside the mesh of the cylindrical sieve during screening, and it must be cleaned regularly, otherwise, when the particles continue to block the mesh, the screening effect of the cylindrical sieve will be affected. Reduced work efficie...
