Abstract
The present invention relates to an impact type dust-collecting electric hammer which comprises an impact electric hammer body, wherein the periphery of an impact bar of the electric hammer body is provided with a helical telescopic dust-sucking cylinder; the tail end of a handle of the electric hammer body is provided with an axial flow fan of which the blade wheel is driven by a motor shaft of the electric hammer body, a suction hole of the fan is connected with one end of the dust-sucking cylinder by a dust-collecting pipe, and the surface which is perpendicular to the suction hole has an air outlet provided with a dust-collecting bag. The electric hammer is clean, convenient, sanitary and environmental protective in use, and the dust-collecting efficiency can reach 98% in use; as a depth device is arranged, the drilling depth of a drill bit can be clearly known.
Description
Technical field
The present invention relates to a kind of impact type electric hammer, specifically, relate to a kind of impact type dust collecting electric hammer.
Background technology
Existing impact type electric hammer during work, stirs up a cloud of dust, and is unfavorable for health of operators, and environment is caused great pollution.And its drilling depth can only be estimated with staff's sensation during work, and is therefore very inaccurate.
Summary of the invention
The purpose of this invention is to provide a kind of impact type dust collecting electric hammer.
Impact type dust collecting electric hammer of the present invention, comprise and impact the electric hammer body, outer periphery at the impact bar of electric hammer body is equipped with spiral expansion sweep-up tube, the handle tail end of electric hammer body is provided with axial fan, the impeller of this blower fan is driven by the motor shaft of electric hammer body, the air suction opening of blower fan is connected with an end of dust-absorbing tube by the pipe that gathers dust, and the one side vertical with air suction opening is provided with air outlet, and this mouth is equipped with dust collecting sleeve.
Described blower fan and electric hammer body are provided with dividing plate, on Blower Housing, be provided with and the extraneous passage that communicates by dividing plate.
Described electric hammer body is provided with the drilling depth measurement mechanism.
Described drilling depth measurement mechanism comprises the sleeve that is fixed on the electric hammer body, be positioned at the pull bar of sleeve and be fixed on the pull bar, expose the outer rule of sleeve, sleeve is provided with dead-center position, and the front end of described pull bar is connected with has limiting plate centre bore, that be connected with the expansion sweep-up tube.
Described drilling depth measurement mechanism comprises the sleeve that is fixed on the electric hammer body, is positioned at the pull bar of sleeve, is carved with scale on the pull bar, and the front end of described pull bar is connected with has limiting plate central through hole, that be connected with the expansion sweep-up tube.
Cleaning was convenient again when impact type dust collecting electric hammer of the present invention was worked, and health is environmental protection again, and dust collection rate reaches 98% during work, because of being provided with degree of depth device, can knowing and understand the degree of depth that drill bit creeps into.
Description of drawings
Fig. 1 is the structural representation of impact type dust collecting electric hammer of the present invention.
The specific embodiment
Referring to Fig. 1, impact type dust collecting electric hammer of the present invention comprises impact electric hammer body 1, outer periphery at the impact bar 2 of electric hammer body 1 is equipped with spiral expansion sweep-up tube 3, handle 10 tail ends of electric hammer body 1 are provided with axial fan 7, the impeller 5 of this blower fan is driven by the motor shaft 11 of electric hammer body, the air suction opening of blower fan is connected with an end of dust-absorbing tube 3 by the pipe 4 that gathers dust, and the one side vertical with air suction opening is provided with air outlet, and this mouth is equipped with dust collecting sleeve 6.
Described blower fan 7 is separated by dividing plate 9 with electric hammer body 1, can avoid dust to enter electric hammer body 1.On Blower Housing 7, near the passage 8 that dividing plate 9 is provided with and the external world communicates, cooling electric hammer motor can ventilate.
Described electric hammer body 1 is provided with the drilling depth measurement mechanism.This depth measurement device comprises the sleeve 14 that is fixed on the electric hammer body 1, be positioned at the pull bar 12 of sleeve and be fixed on the pull bar 12, expose the rule 13 of sleeve 14, sleeve 14 is provided with dead-center position, and the front end of described pull bar 12 is connected with has limiting plate 15 central through hole, that be connected with expansion sweep-up tube 3.Described rule can be screwed on pull bar 12.When starting working, the outer surface of the front end of drill bit and limiting plate 15 is on same plane, along with drill bit go deep into limiting plate extrusion spiral expansion sweep-up tube, make it compression, pushing drawing rod 12 moves simultaneously, thereby the degree of depth that can observe bit drills advance.
Described drilling depth measurement mechanism can also be following structure: it comprises the sleeve 14 that is fixed on the electric hammer body 1, be positioned at the pull bar 12 of sleeve, be carved with scale on the pull bar, the front end of described pull bar 12 is connected with has limiting plate 15 central through hole, that be connected with expansion sweep-up tube 3.When starting working, the outer surface of the front end of drill bit and limiting plate 15 is on same plane, along with drill bit go deep into limiting plate extrusion spiral expansion sweep-up tube, make it compression, pushing drawing rod 12 moves simultaneously, thereby the degree of depth that can observe bit drills advance.
Impact type dust collecting electric hammer of the present invention can improve a little with existing impact type electric hammer and make.On existing impact type electric hammer, increase spiral expansion sweep-up tube 3, depth measurement device, the handle end face is provided with a through hole, motor shaft end is provided with flat slot, the flat-ended protrusions that the setting of axial flow blower axle head matches with the flat slot of motor shaft end is connected dust-absorbing tube 3 with the pipe 4 that gathers dust and gets final product with the blower fan air entry.
During work, opening power, electric hammer starts, the air exhauster wheel rotation that is connected with the motor of electric hammer, when the drill bit that is positioned at dust-absorbing tube was holed on materials such as concrete, brick wall or ceramic tile, air exhauster was about to bore earth down, and sand and dust are managed the inspiration dust collecting sleeve through gathering dust.Dust collecting sleeve can be unloaded and remove car soil to a certain degree when the dust of dust collecting sleeve is long-pending, it be loaded onto to work on again.
