The utility model discloses a rock core drilling machine slurry supply device which comprises a slurry pump and a pump station providing high-pressure oil for the slurry pump, an output end pipeline of the pump station is connected with a flow dividing device capable of dividing the high-pressure oil, one liquid outlet of the flow dividing device is connected with the slurry pump, and the other liquid outlet of the flow dividing device is connected with the pump station. And the other liquid outlet of the shunting device is in pipeline connection with a hydraulic motor. High-pressure oil is shunted through the shunting device, and when the pressure in the drill rod rises to a specified degree, the flow of the high-pressure oil supplied to the slurry pump is reduced through the shunting device, so that the rotating speed of the slurry pump is reduced, the output flow of the slurry is reduced, the flow of the slurry in the drill rod tends to be slow, and the pressure in the drill rod naturally drops; therefore,
