Abstract
Abstract A device includes a transducer for measuring the amount of grain lost by the thresher and a transducer for measuring the amount of grain supplied to the hopper of a grain combine which transducers are connected through an electronic unit in the form of a ratio detector to an indicator calibrated in relative units to register the ratio of the output signals of the transducers for indicating the the magnitudes or rates of grain flow and of the changes in the process of separation of grain in the grain combine. The transducer for measuring the amount of grain supplied to the hopper of the grain combine is installed under the sieve of the cleaner and has an elongated form and a width which is smaller than that of the sieve of the grain combine. The utilization of the device reduces the losses of grain in the thresher and improves labour productivity.
