A dust absorption fan is arranged on a drilling clip top or a driver and a clutch connected with the dust absorption fan are arranged on a drilling rod to ensure the fan turns synchronously with the drilling clip top and the drilling rod. A sucker and an inlet are arranged on a work piece surface hole collar, and the drilling rod, the drilling clip top, a dust air passage of the fan, and a wind exhausting pipe are connected hermetically into a filtering dust bag. The utility model can effectively avoid work dust pollution by the electric drill and the electric hammer and has simple structure and apparent energy-saving effect.
Description
The dust exhaust apparatus of the dust that the utility model produces when relating to a kind of removing electric drill electric hammer (being electric impact drill) work especially can depend on the dust catcher of the instant dust suction of motor power work of electric drill.
At present, the method for the dust that known removing electric drill electric hammer work produces mostly is to carry out after the work of electric drill electric hammer.Because the dust that produces during the work of electric drill electric hammer flies upward disperse in a large number in air, the worker endures the hardship of airborne dust to the fullest extent, contaminated environment not only, also easily cause anthraco-silicosis because of sucking a large amount of dust, and that cleaning eccysis workplace has been flown upward the all-pervasive dust that comes is difficult especially, especially operation in fitting up the building that comes into operation prevents that dust from flying from polluting is a great problem of construction and decoration industry.External existing a kind of special-purpose dust catcher, but absorb dust because of it adopts individual motor to drive dust absorption fan, purchase cost and use cost are all very big, and carry inconvenience, use trouble, therefore, fail to popularize.
The purpose of this utility model provides the special-purpose dust catcher of a kind of electric drill electric hammer, and it drives without individual motor, but depends on the motor power work of electric drill electric hammer, can not only absorb the work dust synchronously but also immediately.
When the purpose of this utility model was achieved in that the work of electric drill electric hammer, motor, drill chuck, drilling rod, drill bit rotated synchronously, bored (dashing) and hit the dust that working substance produces, through drilling rod dust discharge helical flute discharge work object plane; On the drill chuck of electric drill electric hammer or drilling rod, be provided with and depend on the dust absorption fan that its motor power can rotate thereupon synchronously; Begin from work object plane hell, be provided with and can be enclosed in drilling rod, drill chuck, fan outward as the dust air channel with the flexible dust passage of the sealing of drill bit precession, the exhaust duct that is tightly connected again is to bag dust filter; Porch, the dust air channel sucker that connects with work object plane kiss is set, several involute air intake ducts is set on the sucker introduces air.During work, dust catcher is put drilling rod or drill chuck, boring (percussion drill) assigned work point, allow the sucker kiss be connected on the work object plane, connect power supply, drilling rod, drill chuck rotate with motor, and drill bit work produces dust; The dust catcher fan also rotates synchronously, air channel between sucker and fan produces negative pressure, make the tight work of sucker kiss object plane, form eddy current from involute air intake duct suck air simultaneously, dispel the dust of discharging in drilling rod dust discharge helical flute and the boring, form directed high speed dust air-flow, behind fan, enter bag dust filter by exhaust duct.
Owing to adopt such scheme, the channel flow that the dust that the work of electric drill electric hammer produces can only be crossed sealing with air communication in filter dirt (storage dirt) bag of appointment, the pollution of having avoided the work dust from flying to form aloft; Dust catcher depends on the motor power of electric drill and works, and only increases fan, air channel, drilling rod driver etc., simple in structure, energy-conservation obviously, manufacturing and use cost be low.
The utility model is described in further detail below in conjunction with drawings and Examples.
