AUGER FEEDER OF A CONCRETE MIX AND METHOD OF MANUFACTURING THE AUGER FEEDER

摘要

FIELD: transportation.;SUBSTANCE: group of inventions refers to an auger feeder of concrete mix and a method for manufacturing the same. Auger feeder contains a helical segment. At that auger feeder comprises at least one insert which is manufactured from a material softer than that used for the auger feeder's helical segment. Besides the said at least one insert is mounted on a downstream end of the auger feeder, is annular and comprises a gap passing through this insert and cutting the annular shape in the cross direction. At that the flap is provided for closing at least a portion of the outer surface of the insert periphery in the area of the gap. Besides, this flap at least partially pass above the area of the gap.;EFFECT: technical result is simplification of the auger feeder manufacturing.;6 cl, 13 dwg
