Abstract
The utility model relates to a dust sucking device of an impact drill, which comprises an inner sleeve, an outer sleeve and an impeller, wherein both the inner sleeve and the impeller are made of rubber flexible material, and are mounted below the handle of the impact drill and outside a drill bit clamp, a dust sucking inlet and a dust exhausting outlet are formed on the inner sleeve; the outer sleeve is made of air permeable fabric and used for filtering dust; in the utility model, the rotation of the drill bit is used for driving the impeller to rotate, produced suction force enables dust to be absorbed into the inner sleeve, then the dust enters into the outer sleeve from the dust sucking inlet and the dust exhausting outlet, air is discharged from the outer sleeve, and the dust is accommodated in the outer sleeve for other treatment. The utility model has the benefits as follows: additional power is not required to be added, the problem of dust rising during the work of the impact drill can be solved, and potential safety hazards cannot be caused by any materials.
Description
Technical field
The utility model relates to a kind of dust exhaust apparatus, particularly relates to the dust exhaust apparatus of percussion drill.
Background technology
Percussion drill be in use because the rotation of the high speed of drill bit can cause a large amount of dust to fly upward everywhere, not only contaminated environment but also influence operating personnel's health, and if dust get into eyes and also might cause certain accident.
The utility model content
In order to solve above-mentioned defective, the purpose of the utility model is to provide a kind of percussion drill dust exhaust apparatus, and the problem of dirt powder is simultaneously with low cost in the time of both can having solved percussion drill work, simple installation, and can not cause a hidden trouble.
The technical scheme that the utility model provides is following:
A kind of percussion drill dust exhaust apparatus is made up of overcoat, interior cover and impeller, it is characterized in that: cover one end is fastened on percussion drill handle below and leaves the dust discharge outlet in said, and the other end has a hollow cavity to coat impeller and leaves the dust suction inlet; Said impeller is fastened on one section outer drill bit of drill jig; Said overcoat is installed on the end of outside of inner cover near the percussion drill handle.Cover and impeller are processed by the soft and flexible material of this type of rubber in said.
Said overcoat is that the cloth with certain air permeability is processed.
Put telescopic section in said.
The usefulness of technique scheme is:
Impeller is fastened on the drill bit, rotates the impeller rotation through drill bit and produces suction with cover in the suction of dirt powder, need not add external power source, and the material that is adopted all is a soft materials, can not produce hidden danger to construction.
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
Description of drawings
Fig. 1 is the cutaway view of the utility model
Fig. 2 is the cutaway view of the interior overcoat of the utility model
The specific embodiment
A kind of preferred embodiment of the utility model:
Like Fig. 1, shown in Figure 2; A kind of percussion drill dust exhaust apparatus is made up of overcoat 1, interior cover 2 and impeller 3, and interior cover 2 is processed by the soft and flexible material of this type of rubber with impeller 3; Interior cover 2 is cylinder-like structures of hollow; One end is fastened on percussion drill handle below and leaves dust discharge outlet 21, and the aperture of dust discharge outlet 21 for arranging circlewise on interior cover 2 barrels, the other end have a hollow cavity 22 to coat impeller 3 and leave dust suction inlet 23; Said impeller 3 is processed for rubber, utilizes the elasticity of self can be fastened on one section outer drill bit of drill jig; Cover 2 outsides were overlapped the groove circle 25 on 2 near an end of percussion drill handle in available rope is fastened in said overcoat 1 was installed on.
In cover 2 process by rubber, near percussion drill handle one end one ring-type joint 24 is being arranged, rubber capable of using self elasticity is fastened on the percussion drill drill body; Groove circle 25 is arranged on the ring-type joint 24, be used for fastening overcoat 1, overcoat 1 is processed for the cloth with certain air permeability, can be according to the corresponding gas permeability cloth of percussion drill power selection; In cover telescopic section 26 is arranged on 2, can be in use with percussion drill on the slip clamp group synchronous; In cover 2 lower ends are hollow cavities 22, be used to coat impeller 3, this hollow cavity is having a baffle plate 27 near rotary head folder place, the center has a circular hole 28 to hold drill body to pass through on the baffle plate 27, also having an opening, this opening on the baffle plate 27 is dust suction inlet 23; Cavity other end opening, impeller 3 was rotated when drill body rotated, and dust gets into from opening part, gets into overcoat 1 through dust suction inlet 23 and dust discharge outlet 21.
An above-mentioned specific embodiment that is merely the utility model; But the utility model is not limited to embodiment; Every technical spirit according to the utility model all falls into the protection domain of the utility model technical scheme to any simple modification, equivalent variations and modification that above embodiment did.
