Preferably, a cavity communicated with the negative pressure cavity is formed in the base plate, an internal thread portion is formed in the base plate, an external thread portion is formed on the outer side of the metal ring, the metal ring is fixed on the base plate through the matching of the external thread portion and the internal thread portion, and the first negative pressure hole is communicated with the cavity.
Preferably, a plurality of axial grooves are formed in the friction surface of the grinding wheel, and the axial grooves are communicated with the adjacent second negative pressure holes through radial grooves.
Preferably, the side of the grinding wheel piece, which is opposite to the base plate, is fixed with a sub-grinding wheel piece.
Preferably, the friction surface of the auxiliary grinding wheel is an inclined surface, and the inclined surface is provided with an auxiliary groove communicated with the axial groove.
Preferably, a gasket is disposed between the first negative pressure hole and the second negative pressure hole.
Adopt the beneficial effect that above-mentioned technical scheme brought to lie in: according to the invention, the second negative pressure hole for negative pressure collection is formed in the grinding wheel, so that accurate collection of yak horn powder is realized. Because the grinding wheel is provided with the negative pressure collecting mechanism, the grinding wheel is pertinently reformed for facilitating the disassembly, assembly and replacement of the grinding wheel. Firstly, the grinding wheel adopts a separated grinding wheel piece and a metal ring, and can be quickly disassembled and assembled through bolts. The grinding wheel is connected with the base plate in a threaded screwing mode, so that the grinding wheel is convenient to assemble and disassemble, more importantly, the screwing mode is simple and convenient to operate, and the tightness of connection of the negative pressure passage can be guaranteed without special alignment operation. Through setting up vice grinding wheel, can realize tentatively polishing and the seamless switching of meticulous polishing yak horn. The grooves arranged on the friction surfaces of the grinding wheels can effectively guide and collect powder generated at the grinding positions, and the negative pressure airflow with small flow can effectively collect the powder. The sealing gasket can ensure the connection sealing property between the first negative pressure hole and the second negative pressure hole, more importantly, a buffer layer is formed between the grinding wheel and the metal ring, the parts made of two different materials, namely the grinding wheel and the metal ring, are prevented from generating rigid extrusion and friction in the grinding process, and the grinding wheel is effectively protected.
