Limiting device used on grain screener

Abstract

The invention relates to a grain machining device, in particular to a limiting device used on a grain screener. The limiting device used on the grain screener comprises a steel sleeve joint pipe capable of being arranged on a pipeline air suction channel; the steel sleeve joint pipe is arranged to be bent; one end of the steel sleeve joint pipe is connected with a fastener along the outer surface of the steel sleeve joint pipe; the fastener comprises a muff coupling ring, a clamp seat fixedly connected with the muff coupling ring and a bottom plate arranged below the clamp seat; connection holes are symmetrically formed in the bottom plate; connection threads are arranged at the outer surface of the other end of the steel sleeve joint pipe. By adopting the limiting device used on the grain screener with the technical scheme, the air suction channel is prevented from falling off or moving.

Description

technical field [0001] The invention relates to a grain processing device, in particular to a limit device used on a grain screening machine. Background technique [0002] Grain screening machine is a common primary grain processing equipment, mainly used for grain cleaning, seed selection and grading of various crops such as wheat, rice, corn, soybean, cotton seed, camellia, sorghum, etc. The pipeline of the existing grain screening machine The type suction channel is generally made of flexible materials. Due to the pulsating wind pressure, it often shifts or even falls off, and often needs to be reinstalled manually. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a limiting device used on a grain screening machine to prevent the suction channel from being displaced or falling off. [0004] In order to solve the above-mentioned technical problems, the present invention provides a limit device used on a grain s...
