REAPING UNIT STRUCTURE OF COMBINE HARVESTER

摘要

PROBLEM TO BE SOLVED: To provide a combine harvester in which a rotation sensor for detecting the number of transmission rotation of a reaping unit is installed to the reaping unit so as to be hardly adhered with mud, water and saw dusts. SOLUTION: A rotary drive force from the frame 11 of a reaping unit comprising a transmission case extending from a traveling machine body to be shaken upward and downward is transmitted to a pull up drive case 19 through a reaping blade drive case 12 extending from the extended end of the reaping unit frame 11 and a pull up transmission case 17 rising up from the reaping blade drive case 12. A pull up speed change device 42 is installed in the upper end of the pull up transmission case 17. A rotation sensor 64 is installed to the upper end of the pull up transmission case 17. The rotation sensor 64 detects the number of input rotation of the pull up speed change device 42.
