Abstract
Device and method of on-board weighing of harvested materials on a harvesting machine having a path for the harvested material. The device 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 are one of an electronic balance or scale. The second weighing device is equipped with a weighing platform which is installed in the path of the harvested material. A feed system is included which is independent of the weighing platform The method includes supporting a known fixed mass on the first weighing device, successively weighing the known fixed mass on the first weighing device, feeding, with the feeding system, the harvested material continuously and in successive lots onto the weighing platform of the second weighing device, weighing the harvested material on the second weighing device, and processing signals from the first and second weighing devices using the computer. The computer performs algorithmic processing of the signals to eliminate a dynamic interference effect which results from one of slopes, tilts and vibrations of the harvesting machine.
