The fixed plate assembly is detachably connected with the fixed ring 4. The fixing plate comprises a left fixing plate 121 and a right fixing plate 122 which are semicircular, the centers of straight edges of the left fixing plate 121 and the right fixing plate 122 are semicircular, elastic cushions 124 are fixed at the semicircular depressions of the straight edges of the left fixing plate 121 and the right fixing plate 122, the inner side surfaces of the centers of the left fixing plate 121 and the right fixing plate 122 are in clearance fit with the fixing rings 4, and the elastic cushions 124 are extruded by the left fixing plate 121 and the right fixing plate 122. The left fixing plate 121 is fixedly connected with a fixing rod 13, the fixing rod 13 extends towards the right fixing plate 122, one end of the fixing rod 13 far away from the left fixing plate 121 penetrates through the fixing rod 13 along the thickness direction of the fixing rod 13, a fastener 14 penetrating through the fixing rod 13 and the right fixing plate 122 in threaded connection is installed on the fixing rod 13, and in the embodiment, the fastener 14 comprises a fixing screw.
Referring to fig. 3, the ventilation holes 15 are arc-shaped holes penetrating through the arc plate 221 in the thickness direction of the arc plate 221, and the ventilation holes 15 are located on an extension line of the tangential direction of the grinding disc 16. Fixedly connected with is towards keeping away from connecting pipe 9 that 2 directions of dust cover subassembly extended on induced draft hole 15, and connecting pipe 9 is formed by the plastics preparation of stereoplasm, induced draft hole 15 and corrugated hose 10 intercommunication. Through setting up connecting pipe 9, conveniently with corrugated hose 10 and exhaust hole 15 intercommunication, be favorable to at the in-process that the angle grinder removed, corrugated hose 10 is difficult for with the 15 separation in exhaust hole.
The implementation principle of the embodiment is as follows:
the dust produced during polishing is blocked between the dust cover assembly 2 and the polishing surface, so that when the angle grinder works, the dust cover assembly 2 is matched with the action of the exhaust fan 17 to suck the dust in the dust cover assembly 2 into the dust collecting bag, and the dust is not easy to form into raised dust under the rotation of the grinding disc 16, thereby reducing the influence of the dust on an operator and the surrounding environment. After the dust of polished surface is collected integrated bag, reduced the dust of polished surface, be favorable to reducing the clearance work load in later stage for the efficiency of work.
Can dismantle the connection through main dust cover 22 and vice dust cover 21, when changing mill 16 into the cutting dish and cutting the stone material, can separate vice dust cover 21 and main dust cover 22, remain main dust cover 22 on the drive division, make main dust cover 22 when the cutting, carry out partial effect of blockking to the dust that flies out from the tangential direction of cutting dish, cooperate air exhauster 17 and corrugated hose 10's effect simultaneously, the dust that will fly out is inhaled in the dust bag, make dust cover assembly 2 can adapt to different use scenes, dust cover assembly 2 has more the suitability.
Through setting up curved convulsions hole 15 to set up convulsions hole 15 on the tangent extension line of mill 16, the setting of convulsions hole 15 is unanimous with the direction that the dust flies from mill 16, makes in the dust is sucked in convulsions hole 15 more easily, the convenient collection to the dust.
When the stone surface is polished, water is generally sprinkled at the polishing surface so as to reduce the temperature between the grinding disc 16 and the polishing surface, and the bristles 123 are arranged so that friction force exists between the bristles 123 and the polishing surface in the moving process of the grinding disc 16, so that the bristles 123 clean dust adhered to the polishing surface, the dust at the polishing surface is swept up, and the dust is favorably sucked into the dust collecting bag.
Through with 16 partial bulges of mill and dust cover subassembly 2, the face of polishing of mill 16 can all with the face contact of polishing of stone material for the progress of polishing of stone material has improved work efficiency, and mill 16 is at the during operation, dust cover subassembly 2 is difficult for with the face contact of polishing of stone material, has reduced the damage to dust cover subassembly 2, has prolonged the life of dust cover subassembly 2. The horizontal position of dust cover subassembly 2 is higher than the setting of mill 16 for mill 16 is at the pivoted in-process, and the inside and outside pressure differential of dust cover subassembly 2 is less, and dust cover subassembly 2 is difficult to be squeezed the deformation, thereby influences the function of its own fender dirt.
By detachably connecting the fixed plate assembly with the fixed ring 4, when the grinding disc 16 is replaced by a cutting disc, the fixed plate assembly can be taken down so as to carry out stone cutting operation; meanwhile, the bristles 123 can be replaced after the bristles 123 are worn; cleaning of the dust cap assembly 2 is also facilitated.
Example 2:
no dust sweep 12 is provided in the dust cap assembly 2, and the rest of the arrangement remains the same as in example 1.
Through directly inhaling the dust cover subassembly 2 with the dust in to directly get into big dust bag in, be difficult for causing the raise dust, make things convenient for staff's clearance.
The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
