The invention discloses an improved long spiral drilling
machine which comprises a
machine body, a power head, a mud scraping device, a running device, a power device and a hydraulic
system, wherein the power head is connected with a
drill rod and is used for driving the
drill rod to rotate around the axis of the
drill rod, and a
drill bit is arranged at one end of the drill rod. The improved long spiral drilling
machine also comprises an upright column, wherein a retaining cylinder is installed on the upright column, and one side of the retaining cylinder is provided with the mud scraping device for clearing the drill rod and / or the
drill bit. Therefore, the improved long spiral drilling machine provided by the invention is simple in structure, firm and reliable, esthetic in appearance, flexible in use, convenient to use, maintain and repair, high in machine transferring efficiency, and capable of greatly relieving the labor intensity of workers, increasing the production efficiency and saving the production cost; the improved long spiral drilling machine is simple and convenient to disassemble and assemble, and a main frame can be arranged on a flat car through a
chassis system of the main frame, thereby greatly shortening the machine transferring time and reducing the transferring
workload; and meanwhile, adhesives on the
drill bit and the drill rod can be removed in real time, thereby improving the operation quality and increasing the operation speed.
