Abstract
A grain cleaning machine comprising a cleaning chamber including a cleaning roll for cleaning uncleaned grain white, a screw conveyor for feeding the uncleaned grain into the cleaning chamber, a discharge adjusting device disposed in a grain outflow region of the cleaning chamber, and a torque sensor for detecting an internal load of the cleaning chamber. The discharge adjusting device is spring-loaded in a direction to stop outflow of white grain from the cleaning chamber, and is movable against the spring load in a direction to enhance outflow of the white grain. The discharge adjusting device is controllable on the basis of torque detection by the torque sensor to maintain the internal load of the cleaning chamber in a predetermined value.
