Title:
TRANSMISSION STRUCTURE OF COMBINE HARVESTER
Document Type and Number:
Japanese Patent JPH0630640
Kind Code:
A
Abstract:

PURPOSE: To always keep raising rate to proper rate and previously prevent occurrence of tearing-off of grain culms by only changing traveling speed of a machine body, corresponding to lodging state of planted grain culms.

CONSTITUTION: The transmission structure of a combine harvester is constituted so as to change rate of power of an engine 11 in a hydrostatic infinitely variable transmission(HST) and then branch and transmit the power from a transmission case 13 to a machine body traveling apparatus 1 and a stem and clum raising apparatus 6 and so as to synchronize raising operation rate to car speed. In this transmission structure, an infinitely variable transmission 15 is interposingly installed from the transmission case 13 to a transmission system to the stem and culms raising apparatus 6 and simultaneously a car speed detection sensor S for detecting traveling speed of the machine body is provided and when detected car speed is prescribed value or below, the sensor S is controlled so as to changeover the infinitely variable transmission to the high speed side.
