Rotary drum type grain impurity remover

Abstract

The invention discloses a rotary drum type grain impurity remover. The rotary drum type grain impurity remover comprises a barrel body, a screening barrel and a cyclone dust-collecting barrel, whereinthe screening barrel is arranged in the barrel body; the two ends of the screening barrel are connected with rotary frames through spring sleeves; the center position of the right side of a rotary barrel frame is fixedly connected with a right sleeve; the left side of the right sleeve communicates with a feeding tube through a telescopic tube; and the right sleeve is sleeved with a feeding device. According to the rotary drum type grain impurity remover disclosed by the invention, the screening barrel, the spring sleeves and the rotary frames are arranged, and the screening barrel is used forcentrifugally screening grains to screen out large-particle solid impurities such as stones; and meanwhile, the spring sleeves enable the screening barrel to vibrate within a certain range, so that plug hole blockage is avoided, and screening efficiency is guaranteed. A hollow right rotary drum, a hollow left rotary drum, a spiral inlet roller, blades, a dust collecting cover and a cyclone sedimentation cylinder are arranged, so that feeding is convenient, dust in the grains is efficiently cleared, and screening and impurity-removal effect is good.

Description

technical field [0001] The invention relates to the field of grain machinery, in particular to a drum type grain remover. Background technique [0002] After the grain is harvested and dried, before it is stored in the barn, it is necessary to remove impurities from the grain to avoid mixing impurities in the grain and reducing the quality of the grain. It is necessary to use impurity removal equipment. The grain cleaning machine is also called a grain cleaning machine. A kind of screening machine, which relies on equipment fans and built-in vibration screening to classify, screen and remove impurities for grain and other economic crops. [0003] The traditional grain cleaning machine has a simple structure. Through the sieve plate and blower, the light grain skin and solid particle impurities in China are screened and winnowed. The grain is easy to accumulate on the sieve plate, which reduces the screening efficiency and lacks a dust collection device. , causing dust to sc...

[0003] The traditional grain cleaning machine has a simple structure. Through the sieve plate and blower, the light grain skin and solid particle impurities in China are screened and winnowed. The grain is easy to accumulate on the sieve plate, which reduces the screening efficiency and lacks a dust collection device. , causing dust to scatter and pollute the working environment, which is not conducive to the health of operators
