Vibrating drilling machine

Abstract

The invention discloses a vibrating drilling machine which is arranged on a mast. The vibrating drilling machine comprises a box body, a spindle penetrating from top to bottom in the middle of the boxbody, two eccentric shafts, a sliding plate disposed on the periphery of the box body, and a buffer device connected between the sliding plate and the box body, wherein the two eccentric shafts are disposed in the box body in the horizontal direction and are symmetric with respect to the spindle. Each eccentric shaft is provided with an eccentric block, a protruding shoulder is formed at the middle of the spindle, the upper end of the spindle is connected with a rotating power head, the lower end of the spindle is connected with a drill rod and a sampler, the mast is provided with a sliding rail, and the sliding plate is disposed on the sliding rail. The vibrating drilling machine slides on the mast through a feeding oil cylinder and the sliding rail. The vibrating drilling machine can achieve effects of no pollution and no disturbance to the soil during sampling, and can also improve the drilling efficiency.

Description

technical field [0001] The invention relates to a drilling rig, in particular to a vibrating drilling rig used for formation exploration and sampling. Background technique [0002] As the global climate continues to change, people pay more and more attention to the protection of the environment. Soil environment issues have become one of the hot spots in the field of environmental science. The formation, development and evolution of soil are the core issues of soil environment theory research. Paleoenvironmental evolution research focuses on high resolution, high accuracy, and high precision. It is necessary to improve the accuracy of soil sampling and analysis. At the same time, higher requirements are placed on sampling equipment, tools, and sampling techniques. It has the characteristics of high yield, good integrity, no pollution, no disturbance, and the sample maintains the original structure and original production state, so that the first-hand real resource and enviro...
