COMBINE

摘要

PROBLEM TO BE SOLVED: To provide a combine in which a pre-treating part and a cereal culm- conveying device of a threshing part transfer always from a low speed side to an objective speed on turning on an electric source. SOLUTION: This combine is provided by driving a driving motor 37 for pre-treatment HST 35 used for driving a conveying chain 46 of a threshing depth-conveying device 45, a conveying belt 52 of a pre-treating part 9 and a feed chain 31 of a threshing part 10 in a decelerating direction so that the output of the pre-treatment HST 35 becomes stopped state on turning on the electric source of the combine. The pre-treatment conveying device (the conveying chain 46 and conveying belt 52) and the feed chain 31 for conveying the cereal culms in the threshing part 10 always start rotations at a low speed and increase speeds to their objective speeds so as to improve the safety of the work.
