Double-layer grain scourer

Abstract

The invention discloses a double-layer grain scourer, which comprises a machine seat and a motor, wherein the machine seat is provided with a machine body, a feeding hopper, a main shaft, a grain spout and a bran suction mouth; grinding wheels, a sieve and a grain grinding cutter are arranged in the machine body; a fan is arranged on the lower part of the machine base; and bran discharge channels are uniformly arranged on the machine body. The scourer is characterized in that: the main shaft is formed by inserting a long shaft in a short shaft; a bearing is arranged at the position of the insertion gap between the long shaft and the short shaft; the long and short shafts are connected with a motor respectively; a belt wheel arranged on the long shaft is greater than the belt wheel arranged on the short shaft; the fan is arranged on the lower part of the short shaft; and the two grinding wheels are overlapped and arranged on the long shaft. The scourer has the advantages that: the differential rotation of the fan and the grinding wheels can be realized; the bran discharge capacity is improved, so that the bran deposition is prevented even if the scourer operates for a long time; the breakage rate of grains is lowered; and the processed grains do not contain bran, so the sieving of the grains for removing bran is avoided and the threshing performance and processing efficiency of the grains are improved greatly.

Description

technical field [0001] The invention belongs to grain processing equipment, in particular to a double-layer grain peeling machine. Background technique [0002] Grain peeling machine is a commonly used grain processing machine, which can dehull grains such as millet, wheat, corn, sorghum and so on. Patent No. CN95205731.X discloses a grain peeling machine, which is composed of a machine base, a body, a main shaft, a grinding wheel, a regulator, a rice flow nozzle, a bran suction device, a fan, a motor, and a belt transmission mechanism connecting the main shaft and the motor . Its working principle is: the grinding wheel and the fan rotate synchronously with the same main shaft. When the grinding wheel peels the grain, a large amount of bran is discharged into the fan room in the machine base through the gap between the sieve and the fuselage shell, and then discharged by the fan. The grain is discharged through the rice mouth. Compared with the traditional vertical rice ...

AI Technical Summary

Problems solved by technology

The main reason is that the grinding wheel and the fan rotate synchronously with the same main shaft. After running for a period of time, the amount of bran discharged by the fan cannot meet the timely discharge of a large amount of bran produced after grain peeling, which will not only cause the accumulation of bran in the fuselage, but also increase the load on the motor. , and it will increase the breakage rate of grains, resulting in waste of grains; in addition, the cleaning rate needs to be improved, although compared with the traditional rice mill, the cleaning rate has been improved, but a small amount of bran will be mixed in the peeled grains Therefore, after the grain is dehulled, it needs to be sieved, and the processing efficiency is low.
