FIELD: agriculture.SUBSTANCE: invention relates to agricultural machinery industry, in particular to the method of separation of grain mixtures, and can be used for post-harvesting grain treatment, as well as for screening bulk material in other fields of industry. The grain-cleaning machine comprises a screening surface, located under the loading device, in the form of two conical sieves coaxially mounted on the axis, facing with the base to the loading device, the drive for the screening surface, the discharging channels of fractions. The drive is made in the form of a reversible motor with the control system providing reversing movements of the upper and lower conical sieves, and also batchwise feeding of the grain mixture and consisting of a control unit connected to the program setting unit and an actuator connected to the dispenser.EFFECT: increased efficiency of cleaning and separation of grain mixture.1 dwg |
