Claims

[Scope of Claim for Utility Model Registration] (1) A storage chamber for a dust bucket is provided at the inner bottom of the fuselage, and the upper inner wall of this storage chamber is designed to guide dust that falls due to its own weight or by being brushed off into the dust bucket. In a dust collector equipped with a hopper frame, the above-mentioned dust bucket is installed inside the storage chamber so as to be able to move up and down, and on the bottom side of the dust bucket, there is an operating arm protruding from the entrance of the storage chamber that can be rotated in one direction. When the operating arm is rotated, the intermediate bending section connected to the operating arm pushes up the dust bucket bag to bring its upper lip into close contact with the bottom opening of the hopper frame, and when the operating arm is rotated in the other direction, the A sealing device for a dust bucket for a dust collector, characterized in that a lift lever configured to allow the dust bucket to be lowered by releasing the push-up by an intermediate bent portion is rotatably attached. (2) The lower end of the operating arm is bent slightly upward to form a front support part, and an intermediate bent part for pushing up the dust bucket is connected to this support part and has a substantially trapezoidal shape with a horizontal upper surface. At the same time, the distal end side of this intermediate bent part is bent downward to form a rear support part, and the distal end side of this support part is bent at a substantially right angle in the lateral direction to form a retaining part. 2. The sealing device for a dust bucket bag for a dust collector according to claim 1, wherein the lift lever is attached to the inner bottom of the dust bucket bag storage chamber so that it can be raised and rotated by supporting front and rear support parts.
