Abstract
The utility model relates to an electric hammer with a blowing device, which comprises an electric hammer body and a drill rod. The blowing device is fixed or movably mounted on the neck of the electric hammer body, a telescopic mechanism parallel to the drill rod is arranged on the blowing device, an air nozzle is mounted at the tail end of the telescopic mechanism, an air outlet of the blowing device is communicated with the air nozzle, and an air outlet of the air nozzle is aligned to the front end of the drill rod. The blowing device works when the electric hammer works, dust caused by drilling is blown off quickly, and operators are prevented from inhaling too much dust, so that affection on health of the operators can be avoided. The blowing device is fixed without causing affection on normal use of a fixed handle, and further, the air nozzle is connected with the telescopic mechanism and is pressed to be synchronous with an exposed portion of the drill rod when the drill rod drills, and accordingly, the electric hammer is reasonable in design and fine in service effect. Besides, the blowing device movably connected can be taken off at any time by the aid of a movable plug and a slot which are matched with each other, and accordingly the electric hammer with the blowing device is flexible and various in service modes.
Description
Technical field:
The utility model relates to a kind of electric hammer, is specifically related to a kind of electric hammer with blowing device.
Background technology:
At present; The drilling rod that is used to the electric hammer of the work that drills through is not taked dust suppression, a large amount of dust of can kicking up during electric hammer work, and the operator does not suck lung unavoidably; It is healthy to influence the workman; When especially the roof being drilled through work, dust almost all falls into operator's head and whole body, does not meet healthy construction requirement.
Summary of the invention:
The utility model is to overcome deficiency and the defective that prior art exists, and a kind of electric hammer with blowing device is provided.
Technical scheme: a kind of electric hammer with blowing device; Comprise electric hammer body and drilling rod; Cervical fixation at the electric hammer body perhaps is movably installed with a blowing device, and this blowing device is provided with the telescoping mechanism parallel with drilling rod, and the end of this telescoping mechanism is equipped with valve; The gas outlet of said blowing device is communicated with this valve, and the front end of drilling rod is aimed in the gas outlet of valve.
Said telescoping mechanism is the inner and outer pipe sleeve structure that is tightly connected, and between inside and outside sleeve pipe, is connected with return spring, and an end of inside and outside casing inner diameter is communicated with the blowing device outlet, and the other end is communicated with valve.
Said telescoping mechanism is an expansion link that is fixed on the valve, and the other end of this expansion link inserts in the guide pipe of blowing device shell side setting, and on this expansion link, is set with return spring, and the gas outlet of blowing device is communicated with valve through flexible pipe.
Plug is set on the power line of blowing device and the jack of coupling is set on the electric hammer body, on the electric hammer body, be provided for driving simultaneously the switch of blowing device work.
The valve lateral surface is provided with rubber blanket.
The beneficial effect of the utility model:
The utility model is installed blowing device at the electric hammer neck; And through telescoping mechanism valve is provided with and aims at the drilling rod front end; Blowing device is also worked simultaneously when electric hammer is worked, and the dust that drills through is dispelled rapidly, prevents that the operator from sucking too much dust and influencing healthy.Fixedly not influencing integral cast handle during blowing device normally uses.Valve is connected with telescoping mechanism in addition, and in the rod boring process, valve is synchronous, reasonable in design by roof pressure and drilling rod exposed parts, and result of use is good.Adopt the blowing device that flexibly connects, cooperate movable plug and jack, can take off blowing device at any time, thereby occupation mode is versatile and flexible.
