The utility model has the advantages of reasonable structure, convenient operation and using, and automatic dedusting.

Description

The dust-collecting type electric angle grinder

One, technical field

The utility model relates to a kind of polishing electric tool, particularly a kind of dust-collecting type electric angle grinder of dedusting automatically.

Two, background technology

When the electric angle grinder that uses is polished at present, because no any dust arrester, the metal that grinding is got off or other powder will from the friction of processing work to around fly upward, make in the air of whole processing site and be full of dust, this not only severe contamination surrounding environment, but also have a strong impact on operator's physical and mental health, even produce occupational disease.

Three, summary of the invention

For overcoming the disadvantage of above-mentioned existence, problem to be solved in the utility model provide a kind of rational in infrastructure, do not influence operation and just can will add the dust-collecting type electric angle grinder that the dust that produces man-hour enters the dust suction cloth bag automatically.The technical solution adopted in the utility model is on the basis of existing electric angle grinder, and the output shaft above the abrasive disc is provided with impeller, is provided with the dust mouth on fixed blade guard; Be fixed with fixed support on the fixed blade guard, movable shelves dust hood with the retainer ring of fixed blade guard be axes sleeve on fixed blade guard, fixed support covers on the movable shelves dust hood, extension spring one end is connected with fixed support, on the other end activity of the being connected grade dust hood; The casing both sides are provided with motion bar, are fixed with the arcuation dust-blocking plate corresponding with abrasive disc on the motion bar, and fixedly cramp is arranged on the fixing hole of motion bar, fixedly are being provided with Locating extension spring between cramp and the motion bar; Fixed blade guard is provided with slot, and the plate correspondence is arranged on the slot of fixed blade guard, and fixed blade guard is provided with guide plate and plate washer; Plate is provided with a grade dirt deflector.Adopt said structure, can be by the wind-force of impeller generation, the dust that will produce when arc dust-blocking plate, movable shelves dust hood and fixed blade guard will be polished imports the dust suction cloth bag; Have rational in infrastructure, manipulate same convenience, automatic advantages such as dedusting.
