Drilling machine cooling liquid filtering device

The invention relates to the field of cooling liquid filtering, in particular to a drilling machine cooling liquid filtering device. The device comprises an underframe, a filtrate tank, a water inlet pipe and the like, a filtrate tank is fixedly connected to the top of the underframe, and a water inlet pipe is fixedly connected to one side of the filtrate tank and communicated with the filtrate tank. An operator introduces cooling liquid containing metal chippings into the liquid inlet pipe, so that the cooling liquid flows into the filter screen from the liquid inlet pipe, small metal chippings in the cooling liquid fall down from gaps of the filter screen and flow into the filtrate pool along the water inlet pipe, then the operator starts the motor, the sliding hollow plate can stir the cooling liquid in the filtrate pool, and the metal chippings are filtered out. When the telescopic column is in contact with the sliding groove in the filtrate tank, the fixed scraper plate scrapes the bottom of the sliding
