Round screen drum with dustproof effect for rice primary processing

Abstract

The invention discloses a round screen drum with the dustproof effect for rice primary processing, which comprises a shell, wherein a drum screen is installed in the shell, a first-stage sealing cover is hinged to the middle position of a left end opening of the drum screen, and a second-stage sealing cover is hinged to the outer side of the first-stage sealing cover; a driving motor connected to the right end of the shell, wherein an exhaust fan is installed on the top of the shell, an air pipe is connected to the rear side of the exhaust fan, and a particle dust collecting box is slidably connected to the lower portion of the shell; and a dust collection water tank which is arranged below the particle dust collecting box, wherein vertical rods are hinged to the front end and the rear end of the left side of the shell, and a bottom frame is fixed to the lower ends of the vertical rods. According to the round screen drum for rice primary processing, the whole screening mechanism is arranged in the shell, meanwhile, the exhaust fan is arranged to collect dust generated by screening, the problem that dust is scattered all around due to direct exposure of the screen is avoided, unified collection and treatment are facilitated, and the problem that the dust pollutes the environment is effectively solved.

Description

technical field [0001] The invention relates to the technical field of rice processing equipment, in particular to a circular sieve cylinder for primary rice processing with a dust-proof effect. Background technique [0002] Paddy is easily mixed with impurities such as stones during the harvest process, so it is necessary to use a screening device to separate the stones and rice during initial processing. The sieving devices currently on the market are prone to generate large dust during use, which is very easy to pollute the surrounding environment, and the existing sieving devices are not convenient to simultaneously remove stones larger than and smaller than the particle size of rice. Therefore, we propose a circular sieve cylinder with dust-proof effect for primary rice processing. Contents of the invention [0003] The purpose of the present invention is to provide a circular sieve cylinder with dust-proof effect for primary processing of rice, to solve the problem ...
