Rock drilling device of rotary drill

Abstract

The rotary drilling rock drilling device comprises a rotary drilling rig body and a liquid supplementing mechanism, a mounting block is arranged at the top of the rotary drilling rig body, an arm rod is arranged on one side of the mounting block, a digging and drilling assembly is arranged on one side of the arm rod, the liquid supplementing mechanism comprises a liquid supplementing box, a liquid drainage hole is formed in the bottom of the liquid supplementing box, and a bending hole is formed in the top of a mounting plate. A bent liquid conveying pipe is arranged in an inner cavity of the bent hole, a liquid flowing hole is formed in the top of the rotary drilling rod, a plurality of liquid distribution holes are formed in the bottom end of the rotary drilling rod in an annular array mode, a plurality of drainage holes are formed in the inner wall of the drill bit in an annular array mode, and an annular groove is formed in the outer wall of the drill bit. By means of the arrangement of the liquid supplementing box, the bent liquid conveying pipe, the liquid passing hole, the annular groove and the sponge ring, wall protecting liquid can be accurately conveyed to the tip end of the drill bit through cooperation of the liquid supplementing box, the bent liquid conveying pipe, the liquid passing hole, the annular groove and the sponge ring, the phenomenon that the wall protecting liquid is wasted is avoided, and the utilization rate of the wall protecting liquid is increased.

Description

technical field [0001] The invention relates to the technical field of building construction equipment, in particular to a rock drilling device for a rotary drilling drill. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. Rotary drilling rig is one of many construction equipment. Rotary drilling rig is a comprehensive drilling rig. It can use a variety of bottom layers. It has the characteristics of fast hole formation, less pollution, and strong mobility. At present, rotary drilling rigs It is mostly used for drilling core work. [0003] When using a ro...

Problems solved by technology

[0003] When using a rotary drilling rig to drill rock cores, in order to avoid the drill bit of the rotary drilling rig being pulled or damaged by the hole wall of the rock, the staff needs to replenish the wall protection fluid to the drill bit of the rotary drilling rig from time to time. The current solution is Pour the wall protection liquid directly at the construction site, and the wall protection liquid will automatically flow into the gap between the rock hole and the drill bit to achieve the purpose of adding the wall protection liquid. During this process, a large amount of wall protection liquid will not flow to the gap between the drill bit and the rock hole. Thereby can cause the waste of resource, have reduced the utilization ratio of wall protection fluid for rotary drilling rig
