Description

Technical field: [0001] The invention relates to the field of grain mass flow sensor calibration and testing machinery, in particular to an impulse type grain mass flow sensor calibration and performance testing device. Background technique: [0002] Accurate measurement of the yield of a plot while a grain combine harvester is harvesting grain is a key factor in monitoring total yield. The development of a high-accuracy, high-stability grain flow sensor is critical to the accuracy of the yield map. During the harvesting process of the combine harvester, the grain flow rate and the vibration environment of the combine harvester cannot be effectively quantitatively controlled, which causes a large technical bottleneck for the calibration and performance test of the grain flow sensor. The calibration and performance test device of the grain flow sensor whose flow can be manually adjusted is of great significance to the development of high-precision and high-stability grain fl...
