Environmentally-friendly abrasive grinding tool for grinding stones

Abstract

The invention discloses an environmentally-friendly abrasive dusting tool for grinding stones, comprising a machine body, wherein the machine body is provided with a dust removal cavity, and the left and right sides of the dust removal cavity are provided with sliding sleeve grooves symmetrically. The top wall of the sleeve is provided with a ventilation duct communicating with the dust removal chamber. The motor is first turned on in the opposite direction, so that the motor shaft and the main driving wheel are reversed, which drives the horizontal axis and cam to rotate. Compared with the transmission grinding tool, the device collects dust through a fan during the grinding process, which prevents the dust generated by the grinding from causing personal injury to the grinding personnel. At the same time, the device can automatically adjust the grinding height, so that it can adjust the polished stone to have different smoothness.
