SLIME LEAKAGE PREVENTING DECICE OF CASING AUGER

摘要

PURPOSE: A slime leakage prevention device for a casing auger of a ground excavator is provided to extend a service life of the casing auger remarkably by blocking leaking slime by a rotary casing. CONSTITUTION: A slime leakage prevention device for a casing auger of a ground excavator comprises an auxiliary cylinder(8) and inclined pressure plates(81). The auxiliary cylinder protruded from the upper end of a rotary casing(6) at a certain height is formed as a bigger diameter than a bottom diameter of a fixed casing(5). The inclined pressure plates formed in the auxiliary cylinder at a certain interval is inclined in a curved form toward a rotation direction of the rotary casing.
