A two-stage emery roller rice mill

Abstract

The invention discloses a two-stage sand-roller rice mill. The rice mill which comprises a bottom plate, wherein a second machine body and a first machine body are respectively arranged at left and right sides of the top end of the bottom plate; a second hopper is arranged at the top end of the second machine body; a neck tube is arranged at the top end of the right side of the second machine body; a frame is connected with the first hopper through a hinge; and a filter screen is arranged at the center position of the frame. The two-stage sand-roller rice mill has the beneficial effects that roll balls are effectively fixed on a vertical bar through clamping blocks when the connecting block is pushed by the roll balls to avoid the vertical bar being damaged by too much friction between the vertical bar and the connecting block; and rice on the filter screen is shaken through the up-and-down movement of the frame and the rice with sand is effectively screened below the filter screen, so that the problems that the rice with sand enters the first machine body and the second machine body, the machine is damaged, some economic loss is caused due to maintenance and the rice milling effect is influenced are avoided.

Description

technical field [0001] The invention relates to the technical field of two-stage emery roller rice mills, in particular to a two-stage emery roller rice mill. Background technique [0002] The working principle of the rice mill is to press the internal pressure of the thallium and the push of the mechanical force to make the rice squeezed in the whitening room, and after self-friction and mutual friction between the brown rice and the grinding wheel, the rice can be quickly removed. The cortex, such as the patent application number 201520103686.7, includes a frame, a rice bran separation mechanism, a first rice milling mechanism, a second rice milling mechanism and a driving source. The bran rice separation mechanism can separate incompletely separated rice from polished rice, The structure of this patent is simple, and the sand grains inside the rice cannot be effectively removed, which will easily cause damage to the machine when the rice is milled, affecting the rice mill...

[0002] The working principle of the rice mill is to press the internal pressure of the thallium and the push of the mechanical force to make the rice squeezed in the whitening room, and after self-friction and mutual friction between the brown rice and the grinding wheel, the rice can be quickly removed. The cortex, such as the patent application number 201520103686.7, includes a frame, a rice bran separation mechanism, a first rice milling mechanism, a second rice milling mechanism and a driving source. The bran rice separation mechanism can separate incompletely separated rice from polished rice, The structure of this patent is simple, and the sand grains inside the rice cannot be effectively removed, which will easily cause damage to the machine when the rice is milled, affecting the rice milling effect of the rice, and manual selection of the sand grains inside the rice is laborious and laborious.
