Claims

[Scope of utility model registration request]

A rotary excavation/earth introduction bucket with a bottom lid that rotates and moves up and down relative to each other is placed inside a casing tube that is propelled as it rotates into the ground.
A plurality of gripper mechanisms for fixing the bucket are disposed on the soil intake chamber of the bucket and move in a radial direction and lock onto the inner wall of the casing tube, and a plurality of gripper mechanisms are provided between the bucket lifting mechanism, the bucket, and each of the gripper mechanisms. , a casing-driven rotary bucket tote device for a vertical excavator, characterized in that a gripper operating mechanism is provided that operates the gripper mechanism to release and fix the bucket in conjunction with the suspension and release of the bucket. .
