Environment-friendly cylindrical screen for grain screening

Abstract

The invention relates to the technical field of grain screening, and discloses an environment-friendly cylindrical screen for grain screening. The environment-friendly cylindrical screen for grain screening comprises a box body, a feeding hopper is fixedly mounted at the upper end of the right side wall of the box body, the discharging end of the feeding hopper penetrates through and extends to the inside of the box body, and a rotating rod is fixedly installed between the front wall and the rear inner wall of the box body, a round sleeve is connected to the outer round surface of the rotatingrod in a sleeving mode, a supporting plate is fixedly arranged at top of the round sleeve, two fixed bearings are fixedly installed at the top of the supporting plate through fixing blocks, a same round screen bucket is fixedly installed between the inner rings of the two fixed bearings, circular rings with slopes are fixedly installed on the inner walls of the left end and the right end of the round screen bucket, and the inner wall of the circular ring located on the right is rotatably connected with a connecting pipe through a bearing seat. The problems of low screening efficiency and poorscreening effect of an existing grain vibrating screen for parallel vibration of grains are solved.

Description

technical field [0001] The invention relates to the technical field of grain screening, in particular to an environment-friendly cylindrical sieve for grain screening. Background technique [0002] The custom of "five grains" gradually formed, referring to five grain crops: rice, wheat, millet, millet, and bean. Millet refers to sorghum, also refers to yellow rice, millet refers to millet, and Shu refers to beans. Today, "five grains" refers to major food crops such as rice, millet, sorghum, soybeans, and wheat, and the so-called "five grains" refers to all food crops in general. [0003] Vibrating sieve is a common screening equipment. Its main principle is to use the vibration of the vibrating sieve and the sieve holes above to remove particulate impurities. It is suitable for screening and separating grains. For screening work, since the grains are stacked up and down in the sieve, it is necessary to wait for the screening of the lower layer of grains to be screened bef...
