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.

Device for controlling the magnitudes or rates of flow of grain supplied to the hopper of a grain combine having a sieve and the losses of grain in its thresher, comprising:

first means located on a grain combine for detecting the amount of grain lost by the thresher and having an output and generating an output signal proportional to the amount of grain lost by the thresher;
second means for detecting the amount of grain supplied to the hopper of the grain combine located under the sieve of the thresher and having an output and generating an output signal proportional to the amount of grain supplied to the hopper, a sensitive surface of said second means for detecting having an elongated form, with the elongated side of the surface being oriented in the direction of the longitudinal axis of the grain combine and the width of the surface being smaller than that of the sieve;
an electronic unit having first and second inputs and an output, said first input of said electronic unit being connected to said output of said first means for detecting the amount of grain lost by the thresher for supplying a signal to said electronic unit proportional to the amount of grain lost by the thresher, said second input of said electronic unit being connected to said output of said second means for detecting the amount of grain supplied to the hopper of the grain combine for supplying to said electronic unit a signal proportional to the amount of grain supplied to the hopper, said electronic unit generating a signal proportional to the ratio of said signals of said first and second means for detecting;
and an indicator having an input and an output, said input of said indicator being connected to said output of said electronic unit for receiving said signal of the electronic unit and transferring its value through the output to a scale connected therewith and calibrated in units characterizing the relative magnitudes or rates of the grain flow and the changes in the process of separation of the grain in the thresher.
