A connection hopper 51 formed with a bent portion 51b curved outward at the lower end and a collection bag tray 52 seated above the bent portion 51b of the connection hopper 51 .

Hereinafter, the operation of the industrial vacuum cleaner having the height adjusting means 100 will be described.

As shown in Figs. 4 to 5,

First of all, when the height of the vacuum cleaner for industrial use is lowered and is carried on a vans and vans,

When the cover 1 of the industrial vacuum cleaner is pressed downward,

The first moving member 41a and the second moving member 42a fixed to the pair of engaging portions 2a are vertically lowered along the guide holes 21 in the vertical frame 20, The leader rod is inserted into the cylinder and the industrial vacuum cleaner is vertically lowered.

After acting as described above,

When the pressing portion 42b-1 is rotated clockwise,

The elastic member 42d contracts and the second moving portion 42a-2 is tightly fixed to one side surface of the guide hole 21 of the vertical frame 20; the first moving portion 42a-1 and the second moving portion 42a- The first moving part 42a-1 and the nut 42c mutually act so that the two moving parts 42a-2 are firmly fixed to both sides of the guide hole 21 and the first moving part 42a-1 and the nut 42c are in close contact with the pair of engaging parts 2a The fixed action is generated mutually organically, and the industrial vacuum cleaner is fixed at a fixed position.

Conversely,

When the industrial vacuum cleaner is put down on a vans or a van at various sites and then used,

When the pressing portion 42b-1 is rotated counterclockwise,

The first moving part 42a-1, the second moving part 42a-2, and the vertical frame 20 are released from the state of being tightly fixed to each other, And the second moving part 42a-2 vertically upward from the lower part to the upper part of the guide hole 21 of the vertical frame 20 and at the same time the rod inserted into the cylinder 30 is restored, The vacuum cleaner is vertically upwardly moved. In such a state, the industrial vacuum cleaner is easily moved to a place where cleaning is required, and a cleaning operation is performed.

On the other hand, when it is adjusted according to the height of an industrial site requiring cleaning,

The pressing portion 42b-1 is rotated in the clockwise direction to fix the industrial vacuum cleaner or the vat 42b-1 is rotated in the clockwise direction in a state where the cover 1 of the industrial vacuum cleaner is pressed downward and then formed at an appropriate height according to the site, After the industrial vacuum cleaner is lowered from the vans, the pressurizing portion 42b-1 is rotated in the counterclockwise direction to appropriately adjust the height of the vacuum cleaner to the height according to the industrial field, and an appropriate height is set according to the action of the cylinder 30 , The pressing portion 42b-1 of the second fixing member is rotated clockwise again to fix the industrial vacuum cleaner.

On the other hand, as shown in Figs. 7 to 8,

The hopper 50 for the collection pack which can receive the collection pack is mounted on the bottom surface of the hopper 3 under the drum main body 2 so that a plurality of folded collection packs are arranged in the collection tray 52, The dust collecting apparatus according to the embodiment of the present invention may be installed in the drum main body 2 and may be installed in the drum body 52. In this case, A predetermined amount is accumulated inside the collection pack. When the dust and the harmful substances accumulated in the collection pack are processed as described above, the cut part of the collection pack is cut off, and it is possible to easily handle it.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention as defined by the appended claims and their equivalents.
