Abstract

The invention provides a crawler type small-sized combined harvester and relates to a combined harvester in agricultural machinery. The crawler type small-sized combined harvester adopts a crawler to walk; a cutting table is arranged at the front end of a big frame; a walking wheel carrier is arranged at the lower part of the big frame; an operating table, a speed changing box, a clutch and an engine are arranged on the big frame; a seat is arranged at the rear part of the big frame; the cutting table mainly consists of a grain lifter, a threshing cage, a big stirring cage, a lower cutting knife, a small stirring cage, an upper cutting knife, a fan and a lifting cage. The crawler type small-sized combined harvester is characterized in that the inclination angle of a sine rotating piece on a threshing cage cover of the threshing cage can be adjusted; a rotating piece on a small stirring cage shaft is a combination of the sine rotating piece and an anti-sine rotating piece; the anti-sine rotating piece is positioned at the tail end of the shaft. The crawler type small-sized combined harvester is more reasonable in whole machine structure and arrangement, small and compact in whole machine structure, convenient to use and wide in adaptability, the negative pressure air separation effect of an air suction fan is good, residues are discharged downwards, and the crawler adopts a triangular layout, so that the effect of the harvester in a rotten field is obviously improved, therefore, the crawler type small-sized combined harvester has a promotional value.

Description

technical field [0001] A crawler-type small combine harvester of the present invention relates to a combine harvester in agricultural machinery. Background technique [0002] Combine harvesters have a long history of development. Combine harvesters can be divided into large combine harvesters, medium combine harvesters, and small combine harvesters according to the power size. The power machine of the small combine harvesters is generally 20-40 horsepower. At present, in hilly areas, crawler-type small combine harvesters are suitable. The crawler-type small combine harvester is mainly composed of a header, a lower cutter, an engine, a gearbox, a large frame, a crawler, a transmission mechanism, a console, and a seat. Due to the unreasonable structure of the existing crawler-type small combine harvesters, the winnowing effect is poor during use, the impurity content after threshing is high, and it is difficult to get to the rotten field. Therefore, it needs to be improved. ...
