Down-the-hole drill with cooling function and for mining exploration

Abstract

The invention relates to a down-the-hole drill with a cooling function and for mining exploration. The down-the-hole drill comprises a base, a top plate, a drill pipe, a processor, a first motor, a cooling mechanism, a lifting plate, a cleaning mechanism, two supporting plates and a plurality of rollers. The cleaning mechanism comprises a cylinder, a moving plate, a pressure sensor, a spring, a flat plate, a cleaning block and two limiting units. The cooling mechanism comprises a water tank, a water pump, a cooling pipe and two water injection components, and the water injection components comprise water injection pipes, sealing plates, fixing units and rotating units. The down-the-hole drill with the cooling function and for mining exploration enables circulating flowing water to flow through a cooling pipe through the cooling mechanism, the heat of the drill pipe is continuously absorbed, the cooling process of the drill pipe is convenient, and the service life of the drill pipe is prolonged; and moreover, the cleaning mechanism is used for extending a cleaning block into a spiral concave groove of the drill pipe which moves upwards, soil in the spiral concave groove is extruded, the cleaning of the drill pipe is realized, and the practicability of the device is improved.

Description

technical field [0001] The invention relates to the field of mineral mining equipment, in particular to a down-the-hole drilling machine with cooling function for mineral mining. Background technique [0002] The down-the-hole drilling rig is an impact rotary drilling rig. Its internal structure is generally different from that of a rock drill. Its gas distribution and piston reciprocating mechanism are independent, that is, the impactor. The front end is directly connected to the drill bit, and the rear end is connected to the drill pipe. In the hole, through the gas distribution device (valve), the piston (hammer) in the impactor reciprocates and hits the drill tail, so that the drill bit impacts the rock at the bottom of the hole, and the high-speed rotation of the impactor in the hole is controlled by a separate The slewing mechanism is realized by a motor or a pneumatic rotating device outside the hole through a drill pipe connected to the rear end of the impactor.
