Four-roller corn thresher

Abstract

The invention relates to a four-roller corn thresher. The four-roller corn thresher comprises a pressing plate, a left side plate, a right side plate, a base plate and a baffle; a left threshing spaceand a right threshing space are formed between the pressing plate, the left side plate, the right side plate, the base plat and the baffle, gaps A are formed in the portion, at the upper left parts of the left threshing space and the right threshing space, at the tail of the pressing plate, and gaps B are formed in the tails of the left side plate and the baffle; threshing parts are arranged at the gaps A, one ends of the threshing parts are fixed to the pressing plate through a locating spring, and the other ends of the threshing parts penetrate through the gaps B to be connected with a thresher body; the threshing parts are wholly or partially formed by movably connecting a threshing part body A and a threshing part body B. According to the four-roller corn thresher, by arranging the threshing parts at the gaps, the purposes of increasing the threshing rate, solving the problem that elastic parts are easily damaged, and shortening the replacing period are achieved.

Description

technical field [0001] The invention relates to a small agricultural thresher, in particular to a four-roller corn thresher. Background technique [0002] As we all know, corn thresher is a widely used small-scale agricultural machinery, and it is a device that can separate corn kernels from stems. [0003] Along with the needs of the society, a kind of double-barrel reverse gear corn thresher with better separation effect has appeared, such as the Chinese invention patent document with the authorized announcement number CN203087029U and the announcement date being July 31, 2013, which specifically discloses It includes two rollers arranged in parallel, the two rollers arranged in parallel are connected by gears, and the upper part of the two rollers arranged in parallel is also provided with a double-connected regulating tile cover. The threshing of the double-drum left and right bins of the present invention changes the single-side threshing mode, the threshing time of th...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned corn thresher still has the following deficiencies: the corn thresher adopts double-rollers and double-drums. During specific work, the threshing rollers with threshing ribs are used to rotate at high speed, and the shells and side plates around the threshing space are extruded and hit for threshing. , the threshing method is relatively simple, and the corn cob cannot be well stressed when the threshing space moves forward, which affects the threshing rate and threshing efficiency, and cannot solve the technical problem of full threshing
