Detailed Description

As shown in fig. 1 and 2, the utility model discloses strike and bore dust collector includes the installation base cover, and the fixed cover of lower extreme of installation base cover is connected on the side of the drill bit seat of strike brill, and the upper end and the dust collection of installation base cover are fought and are connected, and the drill bit of strike brill stretches out processing drilling from the top of the dust collection fill that falls, and the dust that drill bit processing drilling formed falls into the dust collection fill that falls. Above-mentioned scheme adopts and to add the scheme that the dust collector that falls collects the dust that drilling produced on the drill bit seat of percussion drill, and the dust that ceiling drilling processing produced falls into the dust collection and fights, has avoided environmental pollution, can also utilize the top end face control drill bit drilling's that the dust collection fought degree of depth simultaneously, and this scheme has adopted detachable equipment scheme moreover, maintains the change convenience, has the environmental protection characteristics, has improved workman's efficiency of construction simultaneously.

In order to realize the function of installing the base sleeve and meet the requirement of adjusting the height position of the dust falling collecting hopper, as shown in fig. 6, the installation base sleeve comprises the base sleeve and an adjusting sleeve, the lower end of the base sleeve is fixedly sleeved on the side surface of a drill bit seat of the impact drill through internal and external threaded connection, the upper end of the base sleeve and the lower end of the adjusting sleeve form adjustable internal and external threaded connection, the upper end of the adjusting sleeve is connected with the dust falling collecting hopper, and the distance that a drill bit extends out of the top end of the dust falling collecting hopper is adjusted through adjusting the relative position of the adjusting sleeve and the base sleeve. Based on the above scheme, in order to ensure the stability of connection, as shown in fig. 3 and 7, a positioning threaded hole is formed in the side wall of the base sleeve, a positioning bolt is arranged in the positioning threaded hole, and the positioning bolt is screwed down to lock the relative position of the adjusting sleeve and the base sleeve.

In order to realize the function of dust falling collecting hopper and facilitate the disassembly and replacement of parts, as shown in fig. 4, the dust falling collecting hopper of the scheme comprises a reverse frustum-shaped dust falling collecting hopper body, a connecting sleeve edge is arranged at the lower end of the dust falling collecting hopper body, an external thread is arranged on the outer side of the connecting sleeve edge, and the dust falling collecting hopper is connected with the inner and outer threads through the connecting sleeve edge and the upper end of the mounting base sleeve. Based on above scheme, in order to further avoid the dust that drilling produced to scatter, as shown in fig. 4, 5, the dust that falls of this scheme is collected and is fought the top opening border of body and be equipped with flexible ash blocking ferrule, and the cooperation of flexible ash blocking ferrule and ceiling wall prevents that the dust that drilling formed from wanders off and falls out the dust collection fill.

In order to facilitate operation and observation and grasp the timing of ash removal, the dust falling collecting hopper is made of elastic rubber or transparent plastic.

The dust falling collector disclosed by the scheme has two functions of collecting dust and limiting the punching depth. When local electromechanical installation and transformation projects are carried out in rooms such as offices, laboratories and machine rooms which are put into use, expansion bolt holes need to be drilled to install expansion bolts to fix a hanging bracket and the like. When the impact drill is used for drilling a hole in a ceiling, the dust collector is sleeved on the impact drill, so that falling building dust can be collected during operation, and indoor cleanness is guaranteed. In addition, because the total thickness of the building thickness of the floor slab and the upper and lower brushing surfaces of the floor slab is about 200MM, in order to prevent the floor slab from being perforated during drilling or destroy pipelines pre-buried in the floor of the upstairs dwelling houses, the dust collector with corresponding specification and height can be selected according to the specification of the expansion bolt and the depth of the bolt hole, at the moment, the upper end surface of the dust collector becomes a positioning surface of the perforating depth, the floor slab is prevented from being perforated during drilling of the construction side, and the pre-buried pipelines in the floor of the upstairs dwelling houses are prevented from being perforated.

The devices, components, etc. disclosed in this embodiment may be implemented in any conventional and customary manner known in the art, unless otherwise specified.

The dust collector of percussion drill is not limited to the disclosure of the specific embodiments, but the technical solutions presented in the examples can be extended based on the understanding of the person skilled in the art, and the simple alternatives made by the person skilled in the art according to the present solution in combination with common general knowledge also belong to the scope of the present solution.
