Description

technical field [0001] The invention relates to an agricultural equipment, in particular to a rice seed drying and screening device. Background technique [0002] Rice is native to China, and rice was planted in the Yangtze River Basin of China 7,000 years ago. According to different methods, rice can be divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice. Chinese scientist Yuan Longping has made great contributions to the research of hybrid rice and is known as the "father of hybrid rice". The fruit of rice is rice paddy, which is called brown rice after the chaff is removed, and rice can be obtained by grinding the rice bran layer off the brown rice. Nearly half of the world's population feeds on rice. Rice can be eaten in a variety of ways, including rice, rice porridge, rice cakes, rice cakes, and rice wine. In addition to being edible, rice can also be used as industrial raw materials for wine making...

Problems solved by technology

[0003] After the rice is mature, we often use mechanical equipment such as harvesters to collect the grains. The collected seeds are usually stored in the sun. When the rice is harvested, it often contains some straw, shriveled rice husk and dried It will be very inconvenient for people to deal with impurities such as stones
