Roller drill bit lubrication device

Abstract

The invention relates to a bit lubricating device of a rotary drill rig, and mainly solves the technical problem that a diluted oil transport power source and a coordinated control device are additionally arranged on the existing bit lubricating device of the rotary drill rig. The bit lubricating device of the rotary drill rig comprises a blast main and an oil diluting pipe communicated with the blast main; the other end of the oil diluting pipe is connected to an oil tank of diluted oil; the oil diluting pipe is composed of an oil diluting pipe joint and an oil diluting pipe body; the oil diluting pipe joint is a straight pipe and directly connected with the blast main, and an inclined angle of the oil diluting pipe joint and the flow direction of compressed air in the blast main is an acute angle. The lubricating device is extremely significant in lubricating effect, and sensitive to act and react; an energy source is saved and the operating cost is also reduced due to the fact that the transport power source and the coordinated control device are concealed; furthermore, the bit lubricating device is simpler and compacter in structure, and a finite space of the rig is saved. The bit lubricating device can be applied to the rotary drill rigs with various specifications.

Description

technical field [0001] The invention relates to a bit lubricating device of a roller cone drilling machine. Background technique [0002] The roller cone drilling rig is the main large-scale surface rock drilling equipment in the mine, and the cost of the drill bit is one of the key indicators of the mining consumption cost of the surface mine. Because the original design of the roller cone drilling rig is generally not equipped with a bit lubrication device, with the increase of mining tasks, the penetration rate of the roller cone drilling rig also increases, and its axial pressure is also very large, especially in difficult-to-break complex geological conditions with high hardness, difficult When perforating broken and hard-to-discharge ore rocks, the service life of the drill bit is shortened sharply, and the operating efficiency of the drilling rig is affected. [0003] The Chinese patent with the patent application number 200720174333.1 discloses a bit lubricating dev...

Problems solved by technology

[0004] Since the lubricating device is equipped with a special motor and a delivery pump as the power source for thin oil delivery, it occupies a limited space, which makes the structure of the lubricating device for the drill bit not simple and compact, which also increases the maintenance cost and energy consumption accordingly.
