Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of rice sorting machines, in particular, to a self-cleaning rice sorting machine. BACKGROUND

[0002] Rice needs to be processed through multiple processes in the processing plant. After the rice is husked and whitened, it needs to be sorted by a sorting machine and then removed from the color sorter. The sorting machine classifies rice according to size and weight. The vibrator and the multi-stage screen are used to classify and collect rice of different sizes and lengths, and at the same time, the broken rice produced during the whitening process is screened out.

[0003] Rough rice is removed from the husk after passing through the rice mill. Due to the different sizes of rice grains, it is not conducive to selling. Inevitably, some rice will be crushed into broken rice during the whitening process. In order to remove the broken rice and classify rice of different lengths and sizes for sale, the rice is classified by a sorting machine. The traditional sorting machine classifies rice mainly by multi-stage screen. When the diameter of part of the rice grains is close to the size of the screen holes, the rice is easily blocked in the screen holes, causing blockage. When the sorting machine continuously sorts a large amount of rice, the screen is blocked and it is difficult to continue screening. The traditional sorting machine removes the broken rice and dust mixed in the rice by blowing the broken rice and dust mixed in the rice out of the sorting machine by the fan, and the dust and broken rice may be mixed in the screened rice under the action of the wind. The dust and broken rice have a great impact on the health of workers, thereby affecting the efficiency of rice sorting. Therefore, in order to improve the efficiency of the sorting machine in screening rice, a self-cleaning rice sorting machine is needed. SUMMARY
