Abstract:
A method of on-board weighing of harvested materials on a harvesting machine having a path for the harvested material wherein the harvesting machine includes first and second weighing devices disposed near each other on a common support and being connected to an electronic computer, the first and second weighing devices being one of electronic balance or scale, the second weighing device being equipped with a weighing platform which is installed in the path of the harvested material, the harvesting machine further including a feed system which is independent of the weighing platform, and is weighed independently thereof, the method comprising:supporting a known fixed mass on the first weighing device;successively weighing the known fixed mass on the first weighing device;feeding, with the feed system, one lot at a time, the harvested material onto the weighing platform of the second weighing device;weighing only the harvested material on the second weighing device;removing completely the weighed lot of harvested material from the second weighing device; andprocessing signals from the first and second weighing devices using the computer,wherein the computer performs algorithmic processing of the signals to eliminate a dynamic interference effect which results from one of slopes, tilts, or vibrations of the harvesting machine.
