【Abstract】 The need for monitoring the grain flow on combines during harvesting is promoted by the development of modern farm management and agricultural production. An infrared photoelectric detector is employed to measuring the grain flow on a combine clean grain elevator. The operating principle of the device is described, the experimental data are analysed and the probability of developing a combine grain flow monitor is discussed.更多还原
