Abstract

The invention discloses space omnidirectional undisturbed soil sampling equipment to solve the problem that a traditional soil sampling mode cannot obtain undisturbed samples. The undisturbed soil sampling equipment comprises a drilling and soil sampling device, a travelling marching device, a control device and a worktable; the drilling and soil sampling device comprises a soil sampler, a drill rod, a power head and a drill rod guide rail; the power head is arranged in the drill rod guide rail; the soil sampler is arranged on the drill rod; the drill rod comprises a rotating drill rod body and a sampling drill rod body which are connected through thrust bearings; the sampling drill rod body is connected with the power head; the control device comprises a first oil cylinder, a second oil cylinder, a supporting arm and a motor; the first oil cylinder, the second oil cylinder and the supporting arm are arranged on the worktable; the supporting arm is connected with the telescopic end of the second oil cylinder; and the guide rail is arranged on the upper portions of the first oil cylinder and the supporting arm. The space omnidirectional undisturbed soil sampling equipment has the characteristics that the omnidirectional working posture is not limited, the soil sampling position is not limited, the efficiency is high, and retentivity of the sampled undisturbed soil is good.

Description

technical field [0001] The invention belongs to the field of geological exploration, in particular to an all-round undisturbed soil sampling device. Background technique [0002] Soil-taking equipment is widely used in production practice. It is the most basic tool for soil experiments in construction site exploration and sampling technology. Therefore, obtaining undisturbed soil is a very important link in the survey process. However, the current equipment based on undisturbed soil sampling Improvement is only made on the soil extractor itself, and the complete set of equipment used in survey work is rarely improved, and usually the drilling rig is matched with the soil extractor, and the basic operation process is: drilling, cleaning, and sampling. This kind of method has complicated steps to take the undisturbed soil, and the construction period is long. It can only realize the vertical downward soil sampling operation, and the working posture and soil picking position of...
