Abstract
The utility model discloses a dustproof device of drilling equipment. The dustproof device of the drilling equipment comprises a tubular fixing sleeve fixed on the drilling equipment, a bellows hose which is used for accommodating a drill is arranged at the front end of the fixing sleeve, the front end of the hose is provided with a ring seal lip, a support and a hose return spring which are sleeved outside the drill are arranged inside the hose, and the bottom of the fixing sleeve is provided with a dust collection chamber or a connector which is used for connecting an external dust exhaust device. The dustproof device of the drilling equipment has the advantages that when the dustproof device is mounted on the drilling equipment such as a rotary hammer, dust can be completely collected during a drilling process, so that dust leakage can be effectively prevented to avoid environmental pollution and health problems of constructors due to the dust.
Description
Technical field
The utility model belongs to the annex of punch device, is specifically related to a kind of dust guard of punch device.
Background technology
Punch device such as electric hammer are a kind of common tools, use very general in constructions such as interior decoration, equipment installation.Existing punch device is when punching, and drill bit gets out directly discharging of back with powder, makes the construction site dust fly upward everywhere, causes construction environment to pollute, and workmen's health is brought harm.
The utility model content
The purpose of this utility model is to solve the dust pollution question that exists in the prior art, and a kind of dust guard that can eliminate the punch device of dust pollution is provided.
The utility model is achieved by the following technical programs:
The dust guard of punch device, comprise the tubular fixed cover that is fixed on the punch device, be provided with the corrugated flexible hose of receiving drill bit at the front end of described fixed cover, the front end of described flexible pipe is provided with annular seal lip, be provided with the support and the flexible pipe return spring that are enclosed within on the drill bit in described flexible pipe, the bottom of described fixed cover is provided with the interface of dust storage chamber or external dust exhaust.
Described fixed cover is fixed on the drill headstock of described punch device, comprises the base that is fixed on the drill headstock and the loam cake that flexibly connects with base, and described corrugated flexible hose is located at and covers on described.
Described is erected at described sealing lip place, and described flexible pipe return spring is between the loam cake of described support and fixed cover.
Described base is provided with the connector that cooperates with drill headstock, and the inwall of connector is provided with sealing ring.
Bottom with the sealing lip junction on described flexible pipe is provided with the control of dust recess.
The utility model usefulness is: after punch device such as electric hammer are installed the utility model device, dust all can be collected during the punching construction, be prevented that effectively dust from leaking, avoid dust polluting environment, harm workmen's health.
Below in conjunction with embodiment and accompanying drawing the utility model is described in further detail:
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the support schematic diagram in the utility model.
Fig. 3 is use view of the present utility model.
Fig. 4 is another kind of structural representation of the present utility model.
The specific embodiment
Embodiment 1
As shown in Figure 1, punch device is electric hammer 1, and electric hammer 1 comprises drill headstock 2, be located at installation 3 on the drill headstock 2, be fixed on a drill bit 4 of installing on 3.The dust guard of punch device of the present utility model, comprise the tubular fixed cover 5 on the drill headstock 2 that is fixed on electric hammer 1, fixed cover 5 comprises base 53 and adopts the loam cake 51(fixed cover 5 of bayonet socket 52 flexible connections with base 53 also can be overall structure), base 53 is fixed on the drill headstock 2 by connector 54, and the inwall of connector 54 is provided with sealing ring 6 and drill headstock 2 sealings; Be provided with the corrugated flexible hose 8 of receiving drill bit 4 at the front end of loam cake 51, the front end of described flexible pipe 8 is provided with annular seal lip 10, in flexible pipe 8, be provided with the support 11 and the flexible pipe return spring 9 that are enclosed within on the drill bit 4, support 11 is located at sealing lip 10 places, flexible pipe return spring 9 is between the loam cake 51 of support 11 and fixed cover 5, and the bottom of the base 53 of fixed cover 5 is provided with dust storage chamber 12 by interface 7.
The interface 7 of external dust exhaust also can only be established in the bottom of fixed cover 5 in the utility model, is connected with dust collecting container or dust catcher by pipeline and collects dust.
During construction, earlier the base 53 in the utility model device is fixed on the drill headstock 2 of electric hammer 1, again loam cake 51 is fixed on the base 53, fixed cover 5 and the flexible pipe of being made up of base 53 and loam cake 51 can be with drill bit 4 whole environmental sealings like this, sealing lip 10 can effectively seal the construction surface of boring, the dust that drill bit 4 is got out all drops in the flexible pipe 8 and does not leak, support 11 can prevent that drill bit 4 from contacting with flexible pipe 8 and avoid damaging flexible pipe 8, flexible pipe 8 can increase the elasticity that it resets when drill bit 4 is pulled out rear hose 8 along with the deep meeting of drill bit 4 punchings is compressed under the effect of flexible pipe return spring 9.Boring finishes, and upwards lifts electric hammer 1, makes the utility model device upwards, and the dust in the flexible pipe 8 can 7 flow into dust storage chambers 12 through the dust mouth along flexible pipe 8 and fixed cover 5.Install or when needing bit change 4, loam cake 51 is extracted from base 53 got final product, as shown in Figure 3.
See Fig. 4, present embodiment is on the basis of embodiment 1, and the bottom with sealing lip 10 junctions on flexible pipe 8 is provided with control of dust recess 81.During boring, the control of dust recess 81 on the flexible pipe 8 can be collected dust better more.
