A centrifugal rice sieving device

Abstract

The invention relates to a rice screening device, in particular to a centrifugal rice screening device. The centrifugal rice screening device comprises a supporting cabinet, a motor, a speed reducer, a speed reducer output shaft, a coupling, a first bearing, a first incomplete gear, a first shaft, a centrifugal roller, a cover, a second incomplete gear, a second shaft, a screen, a sand collecting box, screening frames, supporting frames, second bearings, a hood and a hopper. The first shaft is clamped on an inner ring of the first bearing, an outer ring of the first bearing is clamped on the supporting frames, and the supporting frames are fixedly arranged on the ground through bolts. The first incomplete gear and the first shaft are connected through a key. One end of the centrifugal roller is fixedly connected with the first shaft, and the other end of the centrifugal roller is fixedly connected with the second shaft. The second incomplete gear and the second shaft are connected through a key, and the second shaft is clamped on the inner ring of the first bearing. The centrifugal rice screening device has the advantages that automatic screening of rice can be achieved, light sundries in rice can be separated, full rice, broken rice and small soil particles are separated through screening, the labor intensity is reduced, and the rice screening quality is improved.

Description

technical field [0001] The invention relates to a rice sifting device, in particular to a centrifugal rice sieving device. Background technique [0002] The rice is obtained after the rice is processed, and the drying of the rice is very important. Farmers generally lay out drying mats on the ground, and then spread the rice on the mats to dry. Due to the open air, wind or other factors, small soil particles and other light impurities will be mixed in the rice after the rice is dried. Therefore, a rice sieving device is needed to sieve out the impurities, so as to obtain relatively clean grain. In addition, due to the fullness of the grain itself and the influence of factors such as the processing process, the rice is easily mixed with incomplete rice grains, which will greatly affect the taste of the rice grains. , so the rice needs to be further screened to separate the broken rice from the whole rice. The traditional rice sieving procedure uses a hand-held rice sieve to...

Farmers generally lay out drying mats on the ground, and then spread the rice on the mats to dry. Due to the open air, wind or other factors, small soil particles and other light impurities will be mixed in the rice after the rice is dried. Therefore, a rice sieving device is needed to sieve out the impurities, so as to obtain relatively clean grain. In addition, due to the fullness of the grain itself and the influence of factors such as the processing process, the rice is easily mixed with incomplete rice grains, which will greatly affect the taste of the rice grains. , so it is necessary to further screen the rice to separate the broken rice from the whole rice

The traditional rice sieving procedure is to use a hand-held rice sieve to sieve out the impurities in the rice and sieve out the broken rice mixed in the rice. It is not only labor-intensive, time-consuming and laborious, but also the screening quality is not high.
