GRAIN LIFTING CYLINDER IN THRESHER

摘要

PROBLEM TO BE SOLVED: To bring the width of a machine body to be narrow as possible by arranging a grain-lifting cylinder and a second reduction cylinder to coincide their shaft centers in front view of the machine body. SOLUTION: A shaking separation unit 40 is installed ranging from the lower side of a threshing chamber 36 to a dust discharging separation chamber 38 and a first gutter 24 for conveying grains by an internally installed screw shaft is installed below the shaking separation unit 40 and a second gutter 28 is installed in the rear of and parallel to the first gutter. Separated grains are lifted and conveyed to a grain tank 42 by a grain lifting cylinder 26 through a first gutter 24 and a first connection case 25. While, grains which have not been separated are lifted and conveyed to the shaking separation unit 40 by a second reduction cylinder 30 through a second connection case 29 installed to the second gutter 28 and its final end and separated again. By arranging the grain-lifting cylinder 26 and the second reduction cylinder 30 to have almost the same shaft center O, O' when viewed from the front, the first and the second cases 25, 29 are brought to have the same shape and both cases are planed to be shared.
