FIELD: agriculture.
SUBSTANCE: invention relates to agriculture machine building. The air-crew device for grains cleaning includes a casing 2 with screw 1 installed inside with possibility of rotation, creating together with casing 2 a separating channel, receiving-loading device 3, discharge branch pipe, fan, hole for cleaned grains removal, and hole for air and light admixture outlet, silo for cleaned grains. Casing 2 of the air-screw device is pipe with diameter corresponding to outside diameter of the screw 1 between the casing 2 wall and screw 1 with clearance permitting screw 1 free rotation. The receiving-loading device 3 is located in top part of the casing 2 to right of the hole of the output branch pipe 6 for air and light admixtures removal, made in left bottom part of the casing 2. The discharge branch pipe with fan 4 is installed in the top part of the casing 2 to left from the hole 7 for the cleaned grains removal, it is made at end of the bottom part of the casing 2 and is connected with silo 8 for the cleaned grains with butterfly plate 9.
EFFECT: invention increases efficiency of grains cleaning , and reduces prime cost of the grains treatment, extensions scope of application.
