Measuring apparatus for spectroscopic examination and throughput recording of a stalk crop flow

摘要

The measurement system at an agricultural harvesting machine, to measure the harvested flow of grains, has a spectrometer (80a) comprising a lamp (86) and a window (84) within a beating plate (64) and a concave mirror (90) and a detector (92). The lamp illuminates the grain flow through the window and reflected light passes back through the window. The spectrometer is located in the immediate vicinity of a flow detection unit (66). The flow detection unit is at the beating plate with a sensor (72) to register the position.
