Description

Technical Field

The exhaust fan 17 is controlled to operate. When the exhaust fan 17 is running, it passes through the second air duct 18 and the first air duct 18. The air duct 15 performs exhaust operation on the dust hood 8 in the upper housing 1 and the lower housing 2 respectively. At this time, the dust generated by the grinding shaft 7 when grinding the workpiece will be sucked into the dust hood 8, and after the dust is sucked into the dust hood 8, it will enter the No. 2 air duct 18 through the No. 1 air duct 15 installed thereon, and the No. 2 air duct 18 is installed with a filter bin 19, and the filter bin 19 is provided with a filter element 20.

The dust is collected and processed, and the hydraulic telescopic rod 22 is extended by controlling the hydraulic telescopic rod 22. When the hydraulic telescopic rod 22 is extended, the upper housing 1 is driven to move upward, and then the grinding shaft 7 in the upper housing 1 is driven away from the grinding shaft 7 in the lower housing 2, and then the distance between the upper housing 1 and the lower housing 2 is adjusted, so that workpieces of different sizes and thicknesses can be ground. The effect of grinding and dust removal is achieved, and the grinding dust is effectively avoided from being inhaled by the operator to affect the health. Compared with the traditional grinding mechanism, the grinding application range is wider.
