Rice stone removal machine is a common grain machinery, in the rice harvest, accompanied by large areas of planting, the harvest is also more convenient and convenient mechanical harvesting, but at the same time, there are often many impurities doped in the harvest of rice, common rice straw, broken rice husks, and doped stone particles during transportation.
At this time, it is necessary to screen the rice to remove the stone operation, otherwise it will affect the quality of the rice, and even cause irreparable damage to the machinery during processing. When rice enters the machine through the levelling device material, so that the material evenly falls on the upper screen surface, through the reciprocating vibration of the screen surface, and the fan produces the comprehensive effect of upward air flow, according to the gravity of rice and stone, the rice is automatically graded, the heavy impurities such as the stone with larger gravity pass through the screen surface and fall to the lower screen surface, and the light impurities move up through the impurity hole and discharge the body.
The lower screen surface has a strict search function, the screen surface does the same vibration, the effect and the upper screen surface is opposite, the larger weight of the stone, the heavy impurity with the sieve surface vibration upward screening movement, through the heavy impurity hole exclusion machinery, to achieve the stone, screening effect. The working effect can be directly viewed through the sealed viewing window, and the proportion of material concentrated on the upper screen surface can be changed by adjusting the screen mesh and butterfly damper.
