Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present application relates to a dust collector that sucks air containing dust such as wood powder by a cyclone mechanism section and collects the dust.

2. Description of the Related Art Conventionally, an air blower that is driven and rotated by a motor to suck air in which dust is suspended is attached to the upper surface of a trolley provided with casters on the lower surface, and this air blower extends upward in communication with its air outlet. While connecting the ventilation duct, attach a cyclone mechanism to the upper part of the cyclone mechanism, and attach and detach the mouth of the dust bag containing the centrifugally separated dust to the lower opening of this cyclone mechanism with a tightening band. The dust collecting bag is mounted so that it can be hung down, and the mouth of the filter bag that stores the air from which the dust has been removed is attached to the upper opening, and the air in which the dust is floating is sucked by the drive of the motor. And then supplies this to the cyclone mechanism, and separates the dust and air in the cyclone mechanism to store the dust in the dust bag and the air in the filter bag. Dust collectors are known.

DISCLOSURE OF THE INVENTION Problems to be Solved by the InventionHowever, according to the above-described conventional dust collector, when the dust bag is removed from the cyclone mechanism unit in order to discard the collected dust, the dust bag is filled with the dust bag, and , There is a risk that the dust that rises in the cyclone mechanism will spill from the mouth of the dust collection bag and stain the floor of the dust collection device and its surroundings. There were defects such as the need to prepare a separate transportation vehicle for transportation.

Means for Solving the Problems Therefore, in order to solve the above-mentioned defects, the present application is mounted on a pillar so as to be able to move up and down, and has a movable base on which a motor and a blower are mounted, and a support bar on this movable base. A cyclone mechanism part that is fixedly supported in a horizontal state and has a mounting means for mounting the mouth part of the dust bag at the bottom and the mouth part of the filter bag at the top, and a suspension mechanism that supports the top part of the filter bag. And an elevating device for elevating and lowering the movable gantry, wherein the cyclone mechanism part is provided with a shielding mechanism for opening and closing a lower through hole of an isolation cylinder constituting the cyclone mechanism part by an external operation. In addition, the base end is tiltably attached to the column,
Moreover, a movable mount equipped with a motor and a blower, and a lifting mechanism for supporting the free end of the movable mount and tilting the movable mount upward from a horizontal position, and a support rod at the free end of the movable mount. Via a cyclone mechanism section equipped with mounting means for mounting the mouth of the dust bag on the bottom and the mouth of the filter bag on the top, and the top of the filter bag. The suspension mechanism for supporting, characterized in that, in the cyclone mechanism section, a shielding mechanism for opening and closing the lower through hole of the isolation cylinder constituting the cyclone mechanism section by an external operation is provided. In order to facilitate the transportation of dust to the disposal site, a pillar is provided on the main carriage, and a sub-truck on which the dust bag is placed is detachably connected to the main carriage. Shut off machine Is an externally operable handle having an axial rod rotatably supported by a concave portion provided in a part of an outer cylinder constituting the cyclone mechanism portion, and one end fixed to the axial rod in the concave portion. And an operating rod having a shield plate for opening and closing the lower through hole of the isolation cylinder at the other end, and is horizontally mounted between the isolation cylinder and the outer cylinder to support the shield plate in the diametrical direction. , And two arc-shaped guide rails that slide and guide to two positions to open and close.

However, when the motor is started with the isolation mechanism operated and the lower through hole of the isolation cylinder is open, the air blower sucks the dust-laden air and sends it into the cyclone mechanism. The air moves under the isolator while swirling in the cyclone mechanism part, and in the process, heavy dust descends and falls into the dust bag, and the air from which the dust is removed moves to the isolator. The air rises into the filter bag through the lower through hole, this air is filtered by the filter bag and is diffused to the outside, and when dust is accumulated and filled in the dust bag in this way, the motor is stopped, and The closing mechanism closes the lower through-hole of the isolation cylinder, thereby blocking the fall of dust rising from the upper part of the dust bag into the isolation cylinder and dust remaining above the isolation cylinder. When the dust bag is closed When the lifting device is operated with the part loosened by operating the attachment means and detached from the outer periphery of the cyclone mechanism part, the movable platform rises, and the blower, filter bag and cyclone mechanism part also rise together. Then, the cyclone mechanism part is separated from the mouth part of the dust collector, and in this state, the sub-carriage is separated from the main car and the dust bag is moved to the disposal site by the sub-carriage. When replacing the empty dust bag in the above-mentioned state, the sub-carriage is connected to the main car, and the elevating device lowers the movable rack to the height position of the dust bag through the support column and then the cyclone. The mouth of the dust bag is tightened on the outer periphery of the lower part of the mechanism part by the attaching means, and the lower through hole of the cyclone mechanism part is opened by operating the blocking mechanism.
