Crop machine throughput measurement arrangement derives throughput from distance between pre-baling rollers and crop speed, corrects for displacement force on pre-baling roller

摘要

The arrangement has a distance measurement arrangement (36,38,40) for pre-baling rollers and a crop speed measurement device (52), from whose signals the throughput is derived by a controller (46). The controller corrects the result using a signal from a force transducer (48) near the maximum limit position of a pre-baling roller (20), for detecting the displacement force acting on the roller. Independent claims are also included for a method of measuring the throughput in an agricultural crop machine and for a crop machine.
