Description

Technical Field

[0001] The utility model relates to the technical field of rice processing, in particular to a stone removing device for rice processing. Background Art

[0002] The changing quality of raw rice and the increasing complexity of processing technology have led to the continuous progress and development of rice processing technology. Only by continuously improving rice processing technology and equipment, optimizing operating skills, and making full, effective and reasonable use of rice resources in terms of rice cleaning, separation of rice husking and husking, rice milling and finished product finishing, can high-grade and high-quality rice be processed and high-yield and efficient rice processing be achieved.

[0003] At present, the commonly used raw rice cleaning process is: raw rice, primary cleaning, screening, stone removal, magnetic separation, and rice cleaning. Impurities are removed through several steps such as wind separation, screening, specific gravity separation, and magnetic separation. Among them, the stone removal step is one of the important steps in rice impurity removal, and its purpose is to discharge the stones mixed in the rice.

[0004] Chinese patent publication number CN219093000U discloses a rice processing stone removal device, which can continuously and evenly load rice when processing and removing stones by arranging a transmission shaft, a loading rack, a loading belt and a second driving motor, thereby avoiding excessive or intermittent loading, and improving the processing efficiency and quality of rice. By arranging a dust filter bag, a discharge channel, an exhaust fan, an exhaust duct, an exhaust duct, a dust collecting hood and a first mesh plate, dust mixed in the rice can be removed to avoid dust being raised.

[0005] However, compared with the prior art and comparative documents, when removing stones from rice, the rice is conveyed to a conveyor belt inside the machine body by an external feeding device, and then conveyed to one side of the machine body by the conveyor belt for air separation. Due to the uneven feed amount, the rice is easily accumulated when it moves to the surface of the conveyor belt, resulting in uneven rice falling amount. The wind volume generated after a large amount of rice falls cannot effectively blow away the rice and stones, reducing the stone removal effect. In addition, during the air separation process, the rice falls from one end of the conveyor belt. Due to the existence of inertia, the falling path of the rice is in an arc, which makes it easy for the separated stones to hit the machine body, thereby generating noise and damaging the machine body.
