HYDRAULIC CUTTING DRILL HOLE CINDER CONVEYING AND SEPARATING DEVICE

The invention belongs to the field of coal mine gas extraction drilling coal slag cleaning, and relates to a hydraulic slotting and drilling coal slag conveying and separating device. The hydraulic slotting and drilling coal slag conveying and separating device is used for separating coal slag and gas in a drill hole in the drilling and slotting process of a drill rod. The hydraulic slotting and drilling coal slag conveying and separating device comprises a drilling slag collecting device, a coal slag collecting box, a coal slag conveying pump, a coal slag separator and an automatic control system, wherein the drilling slag collecting device, the coal slag collecting box, the coal slag conveying pump and the coal slag separator are sequentially connected through a slag slurry pipe, and the automatic control system is used for controlling the coal slag conveying pump and the coal slag separator to be started and stopped; the drilling slag collecting device is arranged on the outer side of the drill rod and the end of the drill hole in a sleeving manner; the drilling slag collecting device, the coal slag collecting box and the coal slag conveying pump are all connected to a main extraction pipe through a gas extraction pipe; and a stirring impeller is arranged in the coal slag collecting box. The device can achieve automatic starting and stopping, operation is easy and convenient, the coal slag cleaning work human input cost can be effectively reduced, and the work intensity of field personnel is relieved.
