Grain threshing machine having efficient impurity removing function

Abstract

The invention discloses a grain thresher with high-efficiency impurity removal function, which comprises a casing, a feeding hopper is arranged on the top of the casing, threshing rollers are arranged symmetrically on the left and right corresponding to the lower end of the feeding hopper in the casing, and the threshing rollers are set On the roller shaft set in the casing, the roller shaft protrudes out of the casing, and a roller shaft driving mechanism is arranged outside the casing, and a deflector is arranged under the corresponding feeding hopper in the casing, and the deflector is high on the left and low on the right Inclined setting; the left end of the deflector plate is fixedly connected with a sieve plate, the sieve plate is arranged at a downward slope to the left, the other end of the sieve plate is fixed on the left side wall of the housing, and a The first miscellaneous outlet, the upper part of the sieve plate is fixed below the top wall of the housing through a suspender, and the first winch is arranged above the deflector. The present invention provides a grain thresher with an efficient miscellaneous removal function; The invention ingeniously arranges a multi-stage impurity removal mechanism. After threshing, the grains are multi-layered and high-precision impurity removal to obtain clean grains.

Description

technical field [0001] The invention relates to the technical field of grain threshing equipment, in particular to a grain thresher with an efficient impurity removal function. Background technique [0002] With the development of society, my country's agricultural production is developing towards mechanization. Many rural areas have gradually begun to use various agricultural machinery for harvesting and threshing. Among them, rice and wheat threshers are the most widely used, which can greatly reduce farmers' threshing production. labor intensity. When the existing rice-wheat thresher obtains a higher separation yield, the separated grains contain more straw, and the separation effect is not good; and when the separation effect of the straw and grains is better, some grains The grains are brought into the rice straw, resulting in a low yield of separation; while the rice-wheat thresher that can simultaneously increase the separation yield and separation effect has the prob...

Problems solved by technology

When the existing rice-wheat thresher obtains a higher separation yield, the separated grains contain more straw, and the separation effect is not good; and when the separation effect of the straw and grains is better, some grains The grains are brought into the rice straw, resulting in a low yield of separation; while the rice-wheat thresher, which can simultaneously increase the separation yield and separation effect, has the problems of large volume and high input cost.

That is, the rice-wheat thresher in the prior art cannot increase yield, separation efficiency and reduce volume at the same time
