Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

As shown in fig. 1 to 3, the dust suction device for a polishing workshop of the preferred embodiment of the present invention is used for removing dust in the polishing workshop to ensure the health of workers. Including first fender portion, collection dirt portion of enclosing to and connect first fender portion and the second that encloses between the collection dirt portion of enclosing and enclose fender portion, all be equipped with the structure of collecting the dust on the bottom of collection dirt portion and the curb plate, can improve the collection efficiency to the dust greatly.

Based on above-mentioned technical scheme, provide a dust extraction in workshop of polishing in this embodiment for dust collection when polishing emery wheel 10, emery wheel 10 is disc structure, and the realization is polished the work piece through the contact of high-speed rotation time and work piece. During grinding, a workpiece is in contact with the grinding wheel, and dust and ground particles fly out along the tangential direction of the grinding wheel.

Specifically, the housing 20 is included, and the object 20 is a main body structure for enclosing dust and promoting dust collection effect. Specifically, the housing 20 includes two circular first enclosing parts 30, and the two first enclosing parts 30 are used for enclosing two sides of the grinding wheel 10 respectively.
