Problems solved by technology

[0002] At present, there are many types of geological exploration instruments, which can basically meet the needs of foundation exploration. However, in the excavation construction of earthworks such as river channel expansion by dredgers, some detailed geological conditions are required. The original static penetration and dynamic penetration can Effectively explore the bearing capacity of the foundation, but cannot effectively reflect the soil structure, and core drilling and other techniques, and core sampling is generally used for concrete sampling, the equipment is complex, the cost is high, deep sampling is difficult, and the operation is inconvenient

Abstract

The invention provides a geological sampling device. The geological sampling device comprises a drill rod and a first drive device used for driving the drill rod to conduct downward drilling. A hollow cavity is formed in the drill rod. A sample feeding window communicating with the hollow cavity is formed in the end, close to a drill bit, of the drill rod. A sampling barrel is arranged in the hollow cavity in a sliding mode. The sampling barrel is provided with a baffle for plugging the sample feeding window. A second drive device for pushing the sampling baffle to be opened outwards is arranged in the sampling barrel. The geological sampling device further comprises a control device. The control device is used for controlling the first drive device to drive the drill rod to conduct downward drilling, and controlling the second drive device to drive the baffle to be opened after the drill rod reaches a set position. The geological sampling device has the beneficial effects that the sampling equipment is simplified, sampling is facilitated through the arrangement of the sampling barrel, guide-in of impurities is avoided, and the sampling accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of geological sampling, in particular to a geological sampling device. Background technique [0002] At present, there are many types of geological exploration instruments, which can basically meet the needs of foundation exploration. However, in the excavation construction of earthworks such as river channel expansion by dredgers, some detailed geological conditions are required. The original static penetration and dynamic penetration can It can effectively explore the bearing capacity of the foundation, but it cannot effectively reflect the soil structure. Core drilling and other techniques are generally used for concrete sampling. The equipment is complicated, the cost is high, deep sampling is difficult, and the operation is inconvenient. Contents of the invention [0003] The object of the present invention is to provide a geological sampling device in order to overcome the deficiencies of the prior a...
