Grinding disc for grinding ground below wall corners and stone grinding machine adopting same

Abstract

The invention discloses a grinding disc for grinding the ground below wall corners and a stone grinding machine, and belongs to the field of machinery. The grinding disc comprises a grinding disc bodyin an inverted cone shape and grinding blocks uniformly distributed on the lower surface of the grinding disc body; and more than three reinforced grinding block components for grinding the ground with the range of the outer circumference of the grinding disc body are uniformly installed on the grinding disc body in the circumferential direction. The grinding disc and the stone grinding machine have the beneficial effect that by installing the reinforced grinding block components outside the grinding disc body to specially grind the ground below the wall corners, the application range of grinding the ground by the grinding disc is effectively extended.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a grinding disc used for grinding walls and corners and a grinding stone machine using the grinding disc. Background technique [0002] Stone mills are widely used in urban and rural ground facilities and become the new favorite of ground decoration. Yet the grinding disc of the terrazzo machine of the prior art is only applicable to single working ground usually, and some terrazzo machines can only grind flat ground, and are not suitable for the grinding of inclined plane and concave-convex plane; Flat ground grinding, not suitable for grinding straight and concave-convex planes; some are suitable for grinding concave-convex planes, not suitable for grinding inclined and straight planes. Moreover, due to the setting of the grinding disc and the grinding block, the ground at the corner cannot be polished, resulting in a grinding vacuum zone. Contents of the invention [0003] Aiming ...

AI Technical Summary

Problems solved by technology

[0003] Aiming at the problems existing in the prior art that a stone grinder cannot grind a certain width of the ground below a wall corner, and the grinding adaptability of a concave-convex surface is poor, and the grinding effect is not good, the present invention provides a grinding disc for grinding the ground of a wall corner, including an inverted Conical grinding disc body and grinding blocks evenly distributed on the lower surface of the grinding disc body, the grinding disc body is evenly installed with more than three reinforcements for grinding the ground within the outer circumference of the grinding disc body along the outer circumference direction Grinding block assembly
