Multi-factor adjustable drum sieve and multi-factor adjustable drum sieving cleaning device

Abstract

The invention discloses a multi-factor adjustable drum sieve and a multi-factor adjustable drum sieving cleaning device. The multi-factor adjustable drum sieving cleaning device comprises a centrifugal fan (5), an air inlet cover (4), discharging boxes (6) and the drum sieve. The air inlet cover (4) is in a funnel shape, the small-opening end of the air inlet cover (4) serves as an air inlet to be connected with an air outlet of the centrifugal fan (5) through a pipe, the large-opening end of the air inlet cover (4) serves as an air outlet to surround one end of a drum sieve body (3) to form an air channel, a feeding opening (11) is formed in the upper portion of the air inlet cover (4) and provided with a feeding plate, an outlet of the feeding plate extends into the drum sieve body (3), and the discharging boxes (6) are placed below a machine frame (2). The multi-factor adjustable drum sieve and the multi-factor adjustable drum sieving cleaning device are easy and convenient to operate and good in sieving effect, the sizes of meshes of the drum sieve can be changed according to different material varieties, and the multi-factor adjustable drum sieve and the multi-factor adjustable drum sieving cleaning device are wide in application range and high in adaptability.

Description

technical field [0001] The invention relates to the field of sieving and classifying rice seeds, in particular to a multi-factor adjustable cylinder sieve and a cylinder sieving and cleaning device. [0002] Background technique [0003] At present, according to the cleaning principle, there are three main methods of cleaning: plane screening, airflow screening, and pocket screening. The most widely used is the plane screen. However, the planar sieve screens grains through vibration, and the whole machine is heavy, with high vibration and noise and complicated structure. Since the 1980s, experts at home and abroad have adjusted the structure of the combine harvester cleaning device. The cylindrical screen is a new type of cleaning device that breaks through the flat screen. It has a simple structure, light weight, and vibration Small size, low noise and high productivity. At present, the existing cylindrical screens are generally of a separate structure, that is, there a...

AI Technical Summary

Problems solved by technology

At present, the existing cylindrical screens are generally of a separate structure, that is, there are main shafts, guide vanes or spiral guide plates inside, which are troublesome to use. It is difficult to replace the screen mesh of the cylindrical screen, which is labor-intensive and time-consuming, and there are many fault points during work. , the production efficiency is not high, and the parameters are not adjustable, too restrictive and poor in practicability
