Description

Rice stoner Technical Field The utility model belongs to the technical field of rice processing, and particularly relates to a rice stone removing machine. Background The rice stone removing machine is an indispensable device in rice processing, can efficiently remove impurities such as stones and soil blocks mixed into rice, and utilizes the difference of the rice and the impurities in density and shape to realize separation by screening, winnowing and other technologies, so that the rice purity is improved, the follow-up processing is ensured to be smooth, the equipment abrasion is reduced, and high-quality rice is produced. The related art (publication number is CN 216297015U) discloses a rice stone removing machine, which comprises an input pipeline, a shell, a stirring device and a driving device, wherein the input end of the input pipeline is provided with a filtering structure, the upper structure of the shell is a cuboid, the lower structure of the shell is a trapezoid with a big upper part and a small lower part, the shell comprises an inlet communicated with the output end of the input pipeline, a transmission belt arranged at the inlet end, an outlet and a fan arranged on the inner wall of the shell, the stirring device is arranged in the lower structure, and the stirring mechanism comprises a rotating shaft and a turning plate arranged on the rotating shaft and the driving device drives the rotating shaft to rotate.
