TECHNICAL FIELD
[0001] The utility model relates to the technical field of vibration screening and air dust removal for rice processing, and particularly relates to a vibration screening and air dust removal all-in-one machine for rice processing. BACKGROUND
[0002] In the rice processing industry, efficient and accurate processing equipment is the key to improving rice quality and production efficiency. The emergence of a vibration screening and air dust removal all-in-one machine for rice processing is to meet this demand. Rice, as one of the world's important food crops, involves multiple links in the processing process, of which vibration screening and air dust removal are crucial steps. Vibration screening can classify rice according to particle size, removing impurities and broken rice, while air dust removal can effectively remove dust and small impurities on the surface of rice.
[0003] Currently, in the field of rice processing, traditional vibration screening equipment usually uses an eccentric block vibrator or a vibration motor as a vibration source to make rice jump on the screen surface through vibration, thereby achieving the purpose of screening. In terms of air dust removal, the common technology is to use the air generated by a fan to suck away the dust and impurities in the rice, which are separated and collected by a cyclone separator or a bag-type dust collector. Traditional vibration screening equipment and air dust removal equipment usually operate independently, requiring manual material conveying and transferring, which not only increases labor intensity but also easily leads to secondary pollution of materials. In addition, the automation level of traditional equipment is low, making it difficult to meet the needs of large-scale production.
[0004] The existing feeding method mostly adopts manual feeding, which is difficult to ensure the uniformity and stability of feeding. During the long working process, the operator is prone to fatigue and inattentiveness, resulting in inconsistent feeding amount, even concentrated feeding. When the feeding amount is too large at one time, the vibration screen cannot timely screen a large amount of rice, which easily causes material accumulation and affects the screening effect. When the feeding amount is too small at one time, it leads to idle running of the equipment and reduces production efficiency. Concentrated feeding also causes uneven distribution of rice on the screen surface, resulting in insufficient screening and affecting the classification quality of rice. Manual feeding is slow and cannot meet the needs of large-scale production, increasing the production cycle and cost. Therefore, a vibration screening and air dust removal all-in-one machine for rice processing is proposed to solve the above problems. UTILITY MODEL CONTENTS
