Abstract
The invention relates to a measurement apparatus for detecting the mass flow of harvested crops which are conveyed by means of a conveyor. The measurement apparatus comprises a first measuring device for weighing the conveyor together with the conveyed harvested crops, a second measuring device for determining the volume of the harvested crops conveyed by the conveyor, and a computer device for determining the mass density of the harvested crops.
Claims19
A measurement apparatus for determining a mass flow of harvested crops conveyed by a conveyor, comprising:
- a first measuring device for determining a weight of the conveyor and the harvested crops,
- a second measuring device for determining a volume of the harvested crops, and
- a computer device connected to the first measuring device and the second measuring device for calculating a mass density and the mass flow of the harvested crops using the weight and the volume,
- wherein the computer device calculates the mass flow using only the weight currently determined by the first measuring device when a throughput is greater than a threshold and,
- wherein the computer device calculates the mass flow using the volume currently determined by the second measuring device and the mass density of the harvested crops when the throughput is less than the threshold.
