FIELD: agricultural engineering, in particular, grain cleaning and sorting equipment used in enterprises of agricultural, food-processing and mixed feed industry.
SUBSTANCE: pneumatic separating apparatus of grain cleaning machine has fan, pneumatic separation channel, settling chamber, dust catcher, air flow velocity regulator, mechanisms for charging of basic grain mixture and discharging fractions thereof. Dust catcher is of rotational cross-flow type. Dust catcher inlet branch pipe is directly connected with fan outlet branch pipe. Air flow velocity regulator is located within fan. Baffling surfaces are located in inlet branch pipe of dust catcher at an acute angle to its longitudinal axis, one above another in the course of air flow.
EFFECT: increased efficiency in cleaning of used air.
