A rotary drilling rock drilling device

Abstract

The invention discloses a rotary drilling rock drilling device, comprising a rotary drilling rig main body and a liquid replenishing mechanism. A mounting block is provided on the top of the rotary drilling rig main body, an arm rod is provided on one side of the mounting block, and one side of the arm rod is provided with a mounting block. There is a digging and drilling assembly, and the liquid replenishing mechanism includes a liquid replenishing tank. The bottom of the liquid replenishing tank is provided with a drainage hole, and the top of the mounting plate is provided with a bending hole. The bottom end of the rotary drill rod is provided with a plurality of liquid distribution holes in an annular array, the inner wall of the drill bit is provided with a plurality of drainage holes in an annular array, and the outer wall of the drill bit is provided with an annular groove. The present invention utilizes the arrangement of the rehydration box, the bent infusion tube, the liquid drain hole, the annular groove and the sponge ring, and can accurately transport the wall-protecting fluid through the cooperation of the rehydration tank, the bent infusion tube, the liquid drain hole, the annular groove and the sponge ring. To the tip of the drill bit, there will be no waste of wall protection fluid, which improves the utilization rate of wall protection fluid.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a rotary drilling rock drilling device. Background technique [0002] Building construction refers to the production activities in the implementation stage of project construction, and is the construction process of various buildings. It includes foundation 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 forming speed, less pollution and strong mobility. At present, rotary drilling rigs Mostly used for drilling cores. [0003] When using the rotary drilling rig to drill the core of the rock, in order to prevent the drill bit of the rotary drilling rig from being pulled or damaged by the hole wa...

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
