Grinding machine with dust removing device

The utility model belongs to the field of mechanical machining equipment, and particularly relates to a grinding machine with a dust removing device. The grinding machine with the dust removing device comprises a motor installed on a support and two grinding wheels installed on shafts located at the two ends of the motor; protective covers are arranged on the grinding wheels, dust collecting covers connected with the protective covers are arranged under the grinding wheels, and the lower ends of the dust collecting covers are connected with pipelines; the lower ends of the pipelines are connected with an air blower which is coaxially connected with a driven wheel. When the grinding machine machines a workpiece, the air blower is started along with the grinding machine, the air pressure in the pipelines is reduced, therefore, air is made to flow from dust collecting cover openings to a three-way connector along the pipelines to suck dust generated in machining into the pipelines from the dust removing cover openings and discharge the dust from the lower end of the three-way connector. The grinding machine with the dust removing device is simple in structure, good in dust removing effect, and low in cost.
