The other end of the main shaft of the rice milling machine is provided with a cross key groove, one end of the spline sleeve is provided with a cross key connected with the cross key groove, and the side of the spline sleeve away from the main shaft of the rice mill is provided with a pulley, and the pulley The side close to the spline sleeve is provided with a boss matched with the spline sleeve, and the pulley is connected to the output shaft of the drive motor through a belt, and the pulley, the boss, the spline sleeve and the main shaft of the rice mill are coaxially arranged ; The main shaft of the rice milling machine is provided with a cylinder parallel to its axis, and the head of the piston rod of the cylinder is connected to a spline sleeve; Rice mill housing.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to a multifunctional rice mill. Background technique [0002] Rice milling machine is a common grain processing machinery. 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 removed under the extrusion of the horizon...

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
