Problems solved by technology

For example, the publication number is a kind of rotary drilling rig CN202209151U. During the use of this rotary drilling rig, when the drilling slag in the drill bit needs to be discharged, the drill rod and the drill bit need to be taken out simultaneously. Frequently taking out the drill rod and the drill bit will greatly Reduce the drilling efficiency of the drilling rig, and consume more energy, while increasing the labor intensity of the workers

Abstract

An engineering driller capable of efficiently discharging slag relates to the technical field of drilling equipment, and is mainly used for solving the problem of low deslagging efficiency of drillingslag. The engineering driller capable of efficiently discharging slag comprises a driller body, a drill tower is mounted at the front end of the driller body, a power head is mounted on the drill tower, a drilling tool assembly is mounted on the power head, and the drilling tool assembly comprises a rotary excavating drill bit, a drill rod assembly and a slip ring assembly; the rotary excavatingdrill bit comprises a barrel, an upper cover is arranged at the top of the barrel, a torque transmission sleeve is fixedly arranged in the center of the upper cover, and a torque transmission internalspline is fixedly arranged in the torque transmission sleeve; the drill rod assembly comprises a torque transmission drill rod and a plurality of upper drill rods, the slip ring assembly comprises astatic ring and a movable ring, a winch used for lifting the rotary excavating drill bit is fixedly installed on the driller body, and a pulley block is installed at the top of the drill tower. The rotary excavating drill bit can be pulled out of the drill rod to discharge drilling slag, the slag discharging efficiency of drilling is greatly improved, energy is saved, and the engineering driller has the advantages of being simple in structure, convenient to use, high in slag discharging efficiency, capable of saving energy and the like.

Description

technical field [0001] The invention relates to the technical field of drilling equipment, in particular to an engineering drilling rig for efficient slag discharge. Background technique [0002] With the needs of production development, drilling rigs are widely used in various engineering construction fields. Due to the differences in drilling materials and operating environments, people have developed many different types of drilling rigs for various conditions of use, most of which need to drive the drill bit through the drill pipe to complete the drilling work. For example, the publication number is a kind of rotary drilling rig CN202209151U. During the use of this rotary drilling rig, when the drilling slag in the drill bit needs to be discharged, the drill rod and the drill bit need to be taken out simultaneously. Frequently taking out the drill rod and the drill bit will greatly Reduce the drilling efficiency of the drilling rig, and consume more energy, while increa...
