Description

technical field [0001] The invention relates to the field of agricultural machinery and equipment, in particular to a multifunctional rice mill capable of removing impurities. Background technique [0002] The rice mill is a common grain processing machine. Usually the structure of the rice milling machine is mainly composed of a casing, a rice milling mechanism and a fan installed in the casing. The main shaft of the rice milling mechanism is supported on the frame, and the iron roller is fixed outside the main shaft. The iron roller is covered with a screen frame, and the screen frame The outer cover has a casing fixed on the frame. One end of the cavity formed between the screen frame and the iron roller is the rice inlet with the conveying device, and the other end is the rice outlet. When the rice mill is working, the paddy or brown rice is input from the rice inlet, and enters the screen frame under the propulsion of the conveying device, and then is rolled and remove...

AI Technical Summary

Problems solved by technology

[0004] 1. The horizontal ribs on the iron roller are basically set parallel to the iron roller axis, which brings about the problem that the rice temperature is not easy to drop and there are many broken rice;

[0005] 2. The sieve frame has a bead without a rice knife or a rice knife without a bead, which reduces the success rate of peeling small grains of rice, and requires multiple grinding and peeling, which reduces work efficiency;

[0006] 3. When the rice is discharged, use the pressure of the rice to open the rice discharge baffle, and the rice will be extruded from the gap. When the rice processing is completed, some of the rice cannot be discharged, not only the loss of grain, but more importantly, this part of the rice is in the rice mill. It is easy to mold and deteriorate inside, which affects human health, and the rice processing speed cannot be adjusted flexibly;

[0007] 4. When combined with the pulverizer, the function switching is the one-way rotation of the driving wheel and the forward and reverse switching of the motor, which has complex structure, high cost, high failure rate and high maintenance degree
