Description

Graded screening and conveying device for rice Technical Field The utility model relates to the technical field of rice screening, in particular to a rice classifying, screening and conveying device. Background The rice, rice and paddy are annual aquatic herbaceous plants of Gramineae rice, the stalks of the rice are vertical, she Cheng are in a linear needle shape, the panicles of the rice are large and sparse, the small panicles contain 1 mature flowers, the rice is high-temperature, high-humidity and short-day environments, the requirement on soil is not strict, the rice is the most important grain crop in the world, is staple food of more than half of the population in the world, can provide high-quality starch, protein amino acid and vitamins, china is one of origin places of cultivated rice, the area of the rice is about 1/4 of the total area of the rice in the world, the yield is about 45% of the total yield of grains in the whole world, the rice screening is a key link for improving the quality and the subsequent processing efficiency of the rice, the rice screening is operated by means of screening equipment after the rice is harvested and in the earlier stage of processing, the impurities such as grass seeds, rice hulls and clods can be removed, the loss of the subsequent processing equipment is reduced, the high-quality building foundation is high-quality rice production, and great significance is ensured on the quality of the high-quality rice production. But when the discharging material falls on the driving belt for conveying in the rice screening process, the surface of the seeds is easily damaged due to direct collision of the particles and the driving belt, so that the germination rate of high-quality rice seeds is reduced, the appearance quality of commercial rice is reduced, the seed cultivation effect and the market value of products are directly influenced, and the traditional equipment lacks an effective buffering and protecting structure, so that the problem is aggravated, and economic loss and resource waste are caused.
