Abstract
The utility model relates to a dustless dry brill belongs to building construction tool technical field. The dust-free dry drill comprises a driving motor supported on one side of a support, wherein the driving motor is in transmission connection with an output shaft through a transmission mechanism, and a hollow drill bit is installed at the outer end of the output shaft; the support is fixedly connected with a dust collection sleeve which is sleeved outside the output shaft in a sealing mode, the output shaft is provided with a radial hole penetrating through the central hole, the central hole is communicated with the hollow part of the hollow drill bit, the dust collection sleeve is provided with an annular cavity communicated with the radial hole, and one side of the dust collection sleeve extends out of a connecting pipe externally connected with a negative pressure source. During operation, the driving motor drives the hollow drill bit to drill a hole on the wall body in a drilling manner, and falling dust passes through the hollow part of the hollow drill bit in time, the central hole and the radial hole of the output shaft and the annular cavity of the dust collection sleeve and is finally sucked to the dust removal device through the connecting pipe. In this process, the dust hood may block dust from escaping and help draw outside air into the hollow drill bit.
Description
Technical field
The utility model is related to a kind of boring bar tool, especially a kind of dustless drilled dry belongs to construction tool technique neck
Domain.
Background technology
Construction often needs to drill on metope.According to the applicant understood, existing such drilling device is in order to avoid drilling
When dust from flying pollute environment, generally match it is oriented drill out water spray dedusting device, though this wet examination dedusting method can inhibit
Dust, but water source is not only relied on, and inevitably cause metope spot.
Invention content
The purpose of this utility model is that：The shortcomings that existing for the above-mentioned prior art, propose it is a kind of without water source and
It can be to avoid the dustless drilled dry of metope spot.
In order to reach object above, the dustless drilled dry basic technical scheme of the utility model is：Including being supported on holder one
The driving motor of side, the driving motor are sequentially connected by transmission mechanism and output shaft, and the outer end installation of the output shaft is empty
Heart drill bit；The holder is fixedly connected with dust absorption sleeve of the sealing shroud outside output shaft, and the output shaft, which has, runs through centre bore
Radial hole, the centre bore is connected to the hollow space of hollow boring bit, and the dust absorption sleeve has the ring cavity being connected to radial hole
And taking over for external negative pressure source is extended in side.
The utility model further improves, and the hollow boring bit end is equipped with dust cover.
The utility model further improves, and the side of the holder is fixed with rack, and end be connected seat board, in
Portion is set with the casing that can be slid；In described sleeve pipe equipped with rack meshed gears, and support arm is extended in side.
The utility model further perfect is that the driving motor is supported on above the support arm of holder.
The utility model also further improves, and the support arm is mounted in by sealing ring sealing shroud outside output shaft
Dust absorption sleeve is fixedly connected.
When operation, driving motor drives hollow boring bit to drill on wall in a manner of chamfering bit, and the dust fallen will pass through in time
The ring cavity of centre bore of the hollow space of hollow boring bit through output shaft, radial hole and dust absorption sleeve, is finally drawn to dedusting by taking over
Device.In the process, dust hood can be excessive with blocks dust, and helps to suck extraneous air in hollow boring bit.
Description of the drawings
The utility model will be further described below with reference to the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model one embodiment.
Fig. 2 is the side view of Fig. 1.
Specific implementation mode
Embodiment one
As shown in Figure 1, the side of holder 5 is fixed with rack 5-2, end is connected seat board 5-3 for the dustless drilled dry of the present embodiment,
Middle part is set with the casing 5-1 that can be slid.In casing 5-1 equipped with rack 5-2 meshed gears, outside is hinged with lever
Support arm 5-5 is extended in 5-4, side.Driving motor 4 is supported on the top of 5 support arm 5-5 of holder, and driving motor 4 passes through transmission
Mechanism 7 is sequentially connected with output shaft 8, and hollow boring bit 2 is installed in the outer end of output shaft 8.The support arm 5-5 of holder 5 with by sealing
Dust absorption sleeve 3 of the circle 3-1 sealing shrouds outside output shaft 8 is fixedly connected.Output shaft 8 has the radial hole 8- through centre bore 8-1
2, centre bore 8-1 are connected to the hollow space 2-1 of hollow boring bit 2, dust absorption sleeve 3 have the ring cavity 3-2 that is connected to radial hole 8-2 and
Extend the take over 11 of external negative pressure source in side.2 end of hollow boring bit is equipped with the plastic dust cover 1 being connected with seat board 5-3.
When construction, the seat board of holder is fixed on the wall, start driving motor drive hollow boring bit in a manner of chamfering bit
It drills on wall, manipulation operation handle can make the rack of drill bit extending bracket creep into or exit on demand.Drilling the dust fallen will
The ring cavity of centre bore of the hollow space through hollow boring bit through output shaft, radial hole and dust absorption sleeve in time is finally inhaled by taking over
To dust-extraction unit, then blocks dust is excessive for dust hood, and guiding extraneous air enters in hollow boring bit.
It was verified that the dustless drilled dry of the present embodiment has following remarkable advantage：
1. having good dust removing effects, and it is not necessarily to water source, can avoid metope pollution；
2. dust hood can be excessive with blocks dust, and guides extraneous air to enter, play the role of cooling drill bit；
3. installation and manipulation are very convenient.
Claims (5)
1. a kind of dustless drilled dry, including be supported on the driving motor of holder side, the driving motor by transmission mechanism with it is defeated
