Four roller corn thresher

Abstract

The invention relates to a four roller corn thresher. When a left main threshing roller and a left auxiliary threshing roller rotate anticlockwise and a right main threshing roller and a right auxiliary threshing roller rotate clockwise, the left auxiliary threshing roller is installed between a left side plate and a left main threshing roller, and the right auxiliary threshing roller is installedbetween a right side plate and the right main threshing roller; notches A are formed in the two sides of the tail of a pressing plate, and notches B are formed in the tails of the left side plate andthe right side plate; threshing parts are arranged at the notches A, one ends of the threshing parts are fixed to the pressing plate through locating springs, and the other ends of the threshing parts penetrate through the notches B to be connected with a machine body; the threshing part is a whole body or is at least composed of a threshing part A and a threshing part B which are movably connected. By arranging threshing parts at the notches, the purposes of increasing the threshing rate and solving the problems that elastic parts are prone to damage and the replacement cycle is short 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
