Abstract

The utility model relates to a rice-and-wheat thresher, which is capable of separating rice-and-wheat net material from straw, separating grain from grass, with simple structure. The rice-and-wheat thresher comprises a stand, a threshing box, a movable box provided with a wide-meshed screen, a narrow-meshed screen and a grain-collecting hopper. The movable box is arranged above the grain-collecting hopper, the wide-meshed screen in the movable box is arranged above the narrow-meshed screen, and one end of movable box is provided with an air outlet. The threshing box is arranged above the movable box, with a discharge port of the threshing box communicated with the movable box. Since two layers of screens of a wide-meshed screen and narrow-meshed screen are utilized, the screens swing under the function of a bent shaft to separate the net grain with grass and bran dust, achieving the separation of net material and foreign material. The movable box is provided with screens inside, with simple and reasonable structure, which is beneficial to spread.

Description

The dual-purpose thresher of a kind of rice wheat

Technical field

The utility model relates to agricultural machinery, especially relates to a kind of rice-wheat thresher that rice-wheat cleaning matter, foreign material two are separated.

Background content

Existing rice-wheat thresher is of a great variety; these rice-wheat thresher can both separate rice wheat particle with straw; thereby alleviate peasant's work degree, but exist rice wheat detachment machine the not plump paddy of rice-wheat cleaning matter and foreign material can not be separated, rice wheat particle mixes the shortcoming that is difficult to separate with dogstail.

Summary of the invention

The purpose of this utility model is to provide a kind of can make that rice-wheat cleaning matter separates with straw, particle separates with dogstail, the dual-purpose thresher of rice wheat simple in structure.

The purpose of this utility model is achieved in that the utility model comprises frame, threshing case, threshing cylinder, active box, is arranged on wide-meshed screen and fine screen mesh, blower fan and collection grain bucket in the active box, active box is arranged on the top of collection grain bucket, wide-meshed screen in the casing is above fine screen mesh, one end of casing links to each other with blower fan, and the other end is provided with air outlet; Air outlet has a downward outlet and the outlet of a side direction; Threshing cylinder is arranged in the threshing case, and the threshing case is arranged on the top of active box, and its discharging opening communicates with active box, and the threshing case is provided with one and advances Mai Wukou and and advance the paddy mouth.

When using the utility model threshing, paddy and wheat enters into active box by the threshing case after the threshing cylinder threshing, active box separates the particle that breaks away from the drive lower swing of bent axle with straw, dogstail, the wide-meshed screen swing is sent active box with the straw of paddy and wheat, the wind-force of blower fan blows out active box with the dogstail on the fine screen mesh, chaff, dirt, clean particle will drop in the collection grain bucket, reach clean thing with this and will separate with straw, the purpose that particle separates with dogstail.

The beneficial effects of the utility model are: compare with prior art, owing to adopted thick, thin two-layer screen cloth, be the air channel between the two-layer screen cloth, screen cloth makes clean grain separate with dogstail, chaff dirt at the effect lower swing of bent axle, wind-force blows out dogstail, chaff class, reach separating of clean thing and foreign material, it is simple, reasonable that mesh structure is set in the active box, is beneficial to popularization.
