Drum-type rice sieve device

Abstract

The invention relates to a rice sieve device, in particular to a drum-type rice sieve device. The drum-type rice sieve device comprises a motor, a speed reducer, a speed reducer output shaft, a coupler, a first bearing, a first rotating rod, a first shaft, a drum, a seal cover, a second rotating rod, a second shaft, a second supporting seat, a sieve, a dust box, a first supporting seat, a supporting box, a shield, a hopper and a second bearing. The left end of the first shaft is connected with the coupler while the right end of the first shaft is fixedly connected with the drum, the right end of the drum is fixedly connected with the second shaft, the first rotating rod is in key joint with the first shaft, the second rotating rod is in key joint with the second shaft, the sieve is fixed to the dust box through screws, and the dust box is put on the ground. The drum-type rice sieve device has advantages that light impurities in rice can be completely blown out by a fan and a large-pore screen, intact rice grains are screened out under the action of centrifugal force, the sieve is driven by elastic force of springs to separate broken rice and small soil grains, and accordingly labor intensity is relieved, and rice sieving efficiency is improved.

Description

technical field [0001] The invention relates to a rice sifting device, in particular to a drum type rice sieving device. Background technique [0002] After the rice is milled, it needs to be air-dried. Since the rice is air-dried in the open air, coupled with the fullness of the grain itself and the influence of the rice mill, the rice often contains whole rice grains, broken rice, small soil particles, and light impurities. If it is not sieved, it will greatly affect the taste of rice grains and be unhygienic, which will affect the sales price. The traditional way of sieving rice is to sieve rice by manually holding the sieve, which requires a lot of manpower, low screening efficiency and low screening quality, so a rice screening device is needed to screen out impurities in the rice and clean the whole rice. Separate with broken rice sieve. Contents of the invention [0003] The present invention aims to solve the above problems, and provides a drum-type rice sieving ...
