A rice seed impurity rapid screening device and screening method

Abstract

The invention discloses a rice seed impurity rapid screening device and screening method, comprising an outer frame, an inner frame is arranged inside the outer frame, a top surface feeding net is arranged above the inside of the outer frame, and the top surface The center position of the bottom of the feeding net is provided with a first electric push rod, and the extension end of the first electric push rod is fixedly connected with a lifting connecting rod. The surface of the lifting connecting rod is provided with several decelerating filter plates, which are arranged up and down. The deceleration filter plates are far away from each other, and different impurities can be collected through the set grain adsorption tank, dust collection tank, and sand and gravel storage tank. When the first motor inside the grain adsorption tank is started, it drives the exhaust fan. Rotating suction can suck the lighter grains from the rice seeds above the deceleration filter plate into the interior of the grains adsorption tank, and can collect the grains, and the collected grains enter the grains storage tank through the conveying channel for collection , capable of separating grains and grains.

Description

technical field [0001] The invention relates to the technical field of seed screening, in particular to a rapid screening device and screening method for impurities in rice seeds. Background technique [0002] Paddy rice is a cereal crop belonging to Oryza genus, and the representative species is rice. Rice is native to China and India, and was cultivated by the ancestors of the Yangtze River Basin in China 7,000 years ago. Rice is divided into indica rice and japonica rice, early rice and middle and late rice, glutinous rice and non-glutinous rice according to rice type. According to the way of saving seeds, it can be divided into conventional rice and hybrid rice. There are other classifications, which are divided into paddy field rice and floating rice according to whether it is cultivated without soil; divided into seasonal rice and "lazy rice" (regenerated rice after the year) according to the life cycle; divided into ordinary rice and giant rice of about two meters a...

Problems solved by technology

[0004] Impurities need to be removed after rice is harvested. The existing impurity removal device lacks the function of distinguishing different impurities in rice, which will easily lead to waste of recyclable materials such as rice grains mixed with sand and gravel and soil. Some impurity removal devices have relatively limited use, and are likely to cause indoor environment pollution when used indoors. Fibers in the rice float into the air or stick to the skin and easily cause physical discomfort to the staff. The existing impurity removal devices are more efficient. Slow, and the high impurity removal device is not convenient for feeding
