HYDRAULIC DRIVING GEAR FOR SUGAR CANE HARVESTER

PROBLEM TO BE SOLVED: To contrive to simplify arrangement of a hydraulic driving gear and hydraulic circuits so that the driving circuit of the hydraulic driving gear is simplified as much as possible, the numbers of change-over valves and operation levers are lessened and a hydraulic piping structure is simplified in the hydraulic driving gear for a sugar cane harvester, with which each working apparatus is separately driven by each oil motor. SOLUTION: In the hydraulic driving gear for the sugar cane harvester, with which a crop divider 2, a base cutter 3, a drawing apparatus 10, a chopping apparatus 11, a J-shaped chain conveyor 12 for transporting shredded sugar cane slantingly upward, a winnowing apparatus 13 and a suction apparatus 15 are arranged from the front to the rear in order and a great number of pumps are driven by an engine, the crop divider 2, the base cutter 3, the drawing apparatus 10, the chopping apparatus 11 and the J-shaped chain conveyor 12 and the winnowing apparatus 13 and the suction apparatus 15 are driven by independent drive systems, respectively, the oil motors in each hydraulic drive system are successively connected in series, and the change-over valves are intervened only in the hydraulic drive line of the base cutter 3, the draw apparatus 10 and the chopping apparatus 11 and between the pumps.
