A long auger drill

Abstract

The invention discloses a novel long-spiral drilling machine. The machine comprises a machine body, a power head, a mud scraping device, a walking device, a power device and a hydraulic system, wherein the power head is connected with a drill pipe and used for driving the drill pipe to rotate around the axis of the drill pipe; a drill bit is arranged at one end of the drill pipe. The machine further comprises a stand column, a protective barrel is mounted on the stand column, and the mud scraping device used for cleaning the drill pipe and / or the drill bit is arranged on one side of the protective barrel. Accordingly, the novel long-spiral drilling machine is simple in structure, solid, reliable, attractive in appearance, flexible to use and convenient to use and maintain, the transferring efficiency is high, labor intensity of workers can be greatly reduced, the production efficiency is improved, and the production cost is saved; the machine is simple and convenient to disassemble and assemble, a main unit can be arranged on a flat-bed trailer by means of a chassis system, the transferring time of the machine is greatly shortened, and the transferring workload is reduced. Besides, substances attached to the drill bit and the drill pipe can be removed in real time, the operation quality is improved, and the operation speed is increased.

Description

technical field [0001] The invention belongs to engineering machinery, in particular to a long auger drilling machine. Background technique [0002] The most commonly used pile foundation construction equipment is mainly the screw pile machine. The reason is that it has the advantages of simple operation, convenient use, and high drilling efficiency. Influenced by other factors, it only has a narrow construction scope and cannot implement rock formation drilling. Today, buildings are constantly developing in terms of height and space, and they are also facing challenges from various geological conditions in the region, especially highways, viaducts, high-speed railways, etc. Their construction is particularly dependent on more solid pile foundations. At present, these The foundation construction of the building still uses equipment such as rotary drilling, impact drilling or positive and negative circulation drilling rigs to complete the pile foundation construction of larg...

AI Technical Summary

Problems solved by technology

Although the auger drill has improved the structure of the drill pipe and the drill bit, it cannot solve the problem of removing the adhesions on the drill bit and the drill pipe during operation, and at the same time cannot walk, move the machine, and align the pile quickly and conveniently. Therefore, it is urgently needed Improved Design
