Farm-oriented resonance turning air outlet grain screening machine

Abstract

The invention discloses a combination equipment for grain screening and impurity removal, which includes a resonant wind screener and a vibrating grain sheller. Clear, and use the reversing air outlet mechanism in the resonance air outlet screening machine to carry out preliminary clearing of light impurities such as grain husks, and then the grain enters the vibrating grain hulling machine from the resonance air outlet screening machine, and the vibrating grain hulling machine Sprinkle the grain once and completely and thoroughly remove the light impurities in the grain, realize the thoroughness and completeness of clearing the impurities in the grain, and ensure the hygiene and cleanliness of the grain.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an agricultural resonant direction-changing wind-discharging grain sieving machine. Background technique [0002] In the process of grain production, it is necessary to clean up various sizes of soil and gravel in the grain to improve the quality of the grain. At present, there are many kinds of grain cleaning equipment at home and abroad, such as cylinder initial cleaning sieve, vibrating cleaning sieve, flat rotary sieve, stone removal machine, etc.; the structure and function of the above cleaning equipment are relatively simple, and some can only clean coarse impurities. Such as stones, bricks, mud, and some can only clean small impurities, such as fine sand, etc., so it is necessary to increase supporting equipment. In the process layout, it is necessary to add a hoist between the cleaning screen and the stone removal machine, which increases The cost and flo...

Problems solved by technology

At present, there are many kinds of grain cleaning equipment at home and abroad, such as cylinder initial cleaning sieve, vibrating cleaning sieve, flat rotary sieve, stone removal machine, etc.; the structure and function of the above cleaning equipment are relatively simple, and some can only clean coarse impurities. Such as stones, bricks, mud, and some can only clean small impurities, such as fine sand, etc., so it is necessary to increase supporting equipment. In the process layout, it is necessary to add a hoist between the cleaning screen and the stone removal machine, which increases Cost and floor area, operation is also very troublesome; therefore, it is very necessary to design and produce a kind of grain cleaning equipment that can not only clean the coarse impurities in the raw grain, but also clean the fine impurities

[0003] In the Chinese patent with the patent number CN205308773U, a small-scale agricultural drying and grain sifting machine is disclosed. The first-level screen and the second-level screen are arranged inside the sieve box, and the large soil, stones, and straw are separated by the first-level screen. It is equal to the separation of grains, and the grains pass through the secondary screen to screen out small impurities and immature particles, but it cannot realize the resonance of the primary screen and the secondary screen driven by a driving mechanism to improve the screening work of the screen At the same time, the driving mechanism drives the air outlet mechanism to change the direction of the wind, so that the fan covers a wider range
