Abstract

The invention discloses a combing cartridge for combine-harvesters which mainly comprises a fender disc, an intermediate disc, a shaft and a coxcomb, the fender discs are arranged on the two sides, the adjacent coxcombs form a sealed barrel with closing plate, disc and intermediate disc, the tooth outline of the coxcomb is triangular, THE adjacent teeth form a heat shaped combing volume through two semi-circles and a trapezoid of variation in size.

Description

technical field [0001] The invention relates to a comb barrel of a combine harvester. Background technique [0002] Presently known combine harvester combing barrel structure is made up of circular hole type combing tooth plate, octagonal, width disc, shaft, sealing plate, power transmission pulley (or sprocket wheel), bearing block etc. When harvesting, the combing cylinder rotates clockwise at high speed, and the high-speed rotating combing tooth plate guides the ear ends of crops growing in the field to the round-hole-shaped combing cavity and combs them out. It is thrown to the collection area of ​​the combing table, and the mixture is transported to the separating and sorting working parts of the combine harvester through the conveying auger for further threshing and cleaning. Due to the great difference in crop varieties, the round-hole combing chamber has poor adaptability to high-yield or low-yield crops (small cob crops, sparse crops), and it is shown that when har...
