Abstract

The utility model relates to a dustless angle grinder. The utility model is mainly composed of a common angle grinder, an exhaust blower, a filter and a dust suction hood. The utility model has the advantages that the exhaust blower, the filter and the common angle grinder are formed to integration, wind wheels of the exhaust blower are installed on a rotor shaft of a motor of a common angle grinder; when the utility model works, the exhaust blower and grinding wheels rotate simultaneously, and gritty dust or iron chips and sparks ground by the grinding wheels are collected by the dust suction hood; after the gritty dust or the iron chips and the sparks are exhausted by the exhaust blower to the filter to be filtered, clean air is discharged, and thus, the problem that the gritty dust or the iron chips and the sparks fly upwards during the operation of the common angle grinder are solved; damage to eyes of a user is prevented, and the physical health of the user is protected.

Description

Dustless angle grinding machine

The utility model relates to a kind of angle grinding machine.

The angle grinding machine of people's use at present, dust or iron pin Mars fly upward during the polishing construction, and sand dust that grinds or iron pin Mars are polluted the surrounding air of construction site, influence the healthy of user; Serious meeting injury user's eyes.

The purpose of this utility model is to propose a kind of brand-new dustless angle grinding machine, and the problem that sand dust or iron pin Mars fly upward when being used to solve the grinding machine polishing construction of common angle prevents to injure user's eyes, protects that theirs is healthy.

The purpose of this utility model is achieved in that an air exhauster is set between the gearbox of common angle grinding machine and motor, the wind wheel of air exhauster is by on the armature spindle that is loaded on common angle grinding machine motor, the air intake vent of air exhauster is communicated with the air outlet of filter, and the air intake vent of filter is communicated with the dust shield that is positioned at the emery wheel next door; Air exhauster and emery wheel while high speed rotating when its advantage is work, sand dust or iron pin Mars that polishing is discharged are collected by dust shield, after being extracted into filter and filtering by air exhauster, discharge clean air, thus the problem that sand dust or iron pin Mars fly upward when having solved common angle grinding machine polishing construction.

Fig. 1 is a dustless angle grinding machine overall structure schematic diagram.

Below in conjunction with Fig. 1 the utility model is set forth:

Fig. 1 is a dustless angle grinding machine overall structure schematic diagram, (1) is common angle grinding machine among the figure, between the motor (2) and gearbox (3) of common angle grinding machine (1), an air exhauster (4) is housed, the wind wheel (5) of air exhauster (4) is loaded on the armature spindle (6) of common angle grinding machine motor (2); The air intake vent (7) of air exhauster (4) is communicated with the air outlet (9) of filter (8), and the air outlet (10) of air exhauster (4) is communicated with atmosphere; Filter (8) is provided with thin filtering material (11), metal filter screen (12), and metal filter screen (12) is positioned at thin filtering material (11) before, and is provided with removable cover (13), is used for cleaning when opening or changes filtering material; The air intake vent (14) of filter (8) is communicated with the dust shield (16) that is positioned at emery wheel (15) next door; The course of work of the present utility model is such: during the construction polishing, the air exhauster (4) of angle grinding machine (1), emery wheel (15) be the while high speed rotating under the drive of its motor (2), the sand dust, the iron pin Mars that are polished are collected by dust shield (16), be extracted into filter (8) by air exhauster (4) and filter totally, discharge cleaned air by the air outlet (10) of air exhauster (4) then.

So far, the utility model has been carried out comprehensive elaboration.
