Oscillating cutter adaptor for crop harvesting machine

摘要

The adaptor has a double working hydraulic cylinder, or cylinders, and an arrangement for the hydraulic pump to limit the amount and unbalance of the cut material. The harvesting unit (1) comprises a frame (2), oscillating cutter (3), delivery table (4) and a screw conveyor (6). The crop is cut and deposited on the table, gathered, pressed and transferred to an inclined conveyor belt (9). The hydraulic cylinder piston (11) is fastened to the cutter and is moved by pressurisation of the fluid by a pump (12), which is driven by a drive shaft (8) which also drives the conveyors, through pipes (15).
