Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in figure 1, the movable upward drilling dust removal device comprises an upright rod 10, wherein a triangular bracket 19 with a pulley is arranged at the bottom of the upright rod 10, and the pulley has a self-locking structure. The upper part of the upright rod 10 is provided with a plurality of hinge holes 8 at intervals along the axial direction, the drilling machine 1 is fixed at the top, and the long rod 5 can be made of an aluminum alloy material. A plurality of hinge holes 8 are formed in the long rod 5 at intervals in the axial direction, and the vertical rod 10 and the long rod 5 are hinged with the hinge holes 8 through a connecting rod 7 and an operating long rod 9 to form a movable parallelogram structure for connection.

The dust collection device is characterized by further comprising a transparent hemispherical dust collection cover 3 fixed to the top of the vertical rod 10, wherein a circle of rubber corrugated pipe 2 is arranged on the top of the hemispherical dust collection cover 3, and a plurality of small holes are formed in the rubber corrugated pipe 2. The top of the rubber bellows 2 is above the top of the drill holder of the drilling machine 1 and is generally flush with the drill bit after the drill bit is installed. The bottom of the hemispherical dust collecting hood 3 is provided with an opening, the opening is connected with a first vertical pipe 14, and the first vertical pipe 14 is provided with a first fan 4. A water tank 18 is fixed at the bottom of the upright rod 10, and a second fan 12 is arranged at the top of the water tank 18. A dust filter screen 13 is arranged at the air vent of the second fan 12 connected with the water tank 18. And a second standpipe 16 inserted into the tank 18, the bottom of the second standpipe 16 being submerged. The bottom of first standpipe 14 is connected to the top of second standpipe 16 by flexible hose 15.

As shown in fig. 2, the water tank 18 has a half-enclosed column structure, has a horizontal cross section of 3/4 circles, is made of transparent plastic, and has certain elasticity as a whole. An axial through hole 20 is formed in the center of the water tank 18, the diameter of the through hole 20 is slightly smaller than that of the vertical rod 10, the water tank 18 is fixed with the vertical rod 10 in an interference fit mode through the axial through hole 20, and a triangular support 19 is provided with a water tank 18 bearing plate. In order to further improve the stability of the connection between the water tank 18 and the upright 10 during use, the top of the water tank 18 is further provided with a hinge 21 connecting two opposite sides of the semi-surrounding column structure, and one end of the hinge 21 is a movable end. The top of the water tank 18 is provided with a water injection valve 17, and the bottom of the water tank 18 is provided with a drain valve 23. The top of the water tank 18 is provided with an opening 22, the second vertical pipe 16 is connected with the upright rod 10 through the binding band 11, and a sealing ring is arranged at the joint of the second vertical pipe 16 and the opening 22.

As shown in FIG. 3, the device is assembled in the above connection mode, and more than half of the water is filled into the water tank 18 and a certain space is reserved. The drill bit is then secured to the drill 1, the drill 1 is turned on, the device is moved to a predetermined position, the pulleys of the tripod 19 are locked and the first fan 4 and the second fan 12 are turned on. The downward force is then converted to an upward force of the long rod 5 by the movable parallelogram structure by pressing down the operating long rod 9. Initially, the rubber corrugated pipe 2 at the top of the hemispherical dust collection cover 3 and the drill bit are simultaneously contacted with the ceiling; with the long operating rod 9 being pressed downwards continuously, the drill bit is driven into the ceiling, and the upper edge of the rubber corrugated pipe 2 can be in good sealing contact with the ceiling due to good elasticity and compression stroke, so that dust is prevented from escaping from a gap between the rubber corrugated pipe and the ceiling, and obvious resistance cannot be formed for upward punching. First fan 4 is close to the bottom setting of hemisphere dirt catcher 3, and its wind-force is downward for produce the negative pressure in the hemisphere dirt catcher 3, the aperture acts as the air intake on the rubber bellows 2, and the wind and dust that produces when making drilling can be smooth through first standpipe 14, elastic hose 15, the leading-in water tank 18 of second standpipe 16, most dust will be dissolved in aquatic and form turbid liquid. Because the dust itself also has the quality of a bit, it can down move smoothly under action of gravity and negative pressure, therefore first fan 4 only need small-size fan can, it can through fix the battery power supply at stock 5 can.

Hinge holes 6 and 8 on the long rod 5 and the vertical rod 10 are used for adjusting the overall height of the device, and are used for punching different storey height floors, and in addition, the through hole structure of the device greatly reduces the quality of the long rod 5 and reduces the operation force. The water tank in this device sets up to half encirclement structure, its dismouting of being convenient for to it is located the bottom of device, can improve the holistic stability of device greatly after the retaining. When the water in the water tank needs to be replaced again, clean water can be injected through the water injection valve 17 after the water is directly discharged through the water discharge valve 20. Or after the hinge 21 is opened, the whole water tank 18 can be moved down from the upright rod 10 by a little force, the binding belt 11 is unfastened, the second vertical pipe 16 is taken out from the water tank 18, and the water tank 18 is taken to the water source to replace clean water, so that the operation is flexible.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
