Abstract

The invention relates to a cylindrical pre-cleaning screen, which comprises a rotating cylindrical screen, wherein the axis of a rotating shaft of the cylindrical screen is horizontally arranged; the cylindrical screen is provided with a left end part and a right end part; the right end part of the cylindrical screen is provided with a material inlet for delivering materials to be screened, while the left end part is provided with a material outlet for discharging impurities; the inner wall of the cylindrical screen is provided with a spiral material guide groove extended along the axis of the rotating shaft of the cylindrical screen; a screening channel is reserved in the cylindrical screen; a screening hole only allowing clean materials to pass through is reserved on the inner wall of the cylindrical screen; the materials to be screened enter the cylindrical screen from the material inlet, and are screened by the screening channel; and the clean materials are screened out from the screening hole, while the impurities pass through the material guide groove and are discharged out from the material outlet. The cylindrical pre-cleaning screen of the invention changes reverse feeding into forward feeding so as to avoid material blockage when the materials enter a chute, and in addition, makes fuller the screening because the materials flow through the entire length of the cylindrical screen in the screening.

Description

technical field [0001] The invention relates to equipment and devices for cleaning large impurities in grain materials, in particular to a cylinder primary cleaning sieve. Background technique [0002] At present, the cylinder initial cleaning screen is generally suitable for cleaning impurities of grain materials after harvest, such as corn, wheat, rice, soybeans, etc., and separates clean grain and impurities according to the density, thickness and diameter of the material. The process flow is: the raw grain enters the hopper and automatically flows into the sieve cylinder through the chute, and is sieved in the sieve cylinder, the material smaller than the sieve hole falls into the material outlet, and the large miscellaneous material larger than the sieve hole remains in the sieve cylinder and enters the sieve cylinder. Miscellaneous exports. [0003] Generally speaking, the cylinder initial cleaning sieve has a good cleaning effect on large impurities, and the removal ...
