Description

Technical Field

[0001] The utility model relates to the technical field of soil sampling devices, in particular to a geological exploration safety sampling device. Background Art

[0002] Geological exploration refers to the systematic investigation and research of geological structures, rock types, and mineral resources. Its purpose is to understand the Earth's geological structure, geological processes, and the distribution of geological resources, providing a scientific basis for mineral resource development. Geological exploration can inform the prediction and prevention of geological hazards, provide scientific guidance for the exploration and development of mineral resources, and support environmental protection and sustainable development. Sampling surface soil and collecting geological samples is a crucial part of geological exploration. The design of safe sampling equipment is crucial in geological exploration to ensure reliable samples are obtained.

[0003] However, the diameter of the sampler of some sampling devices in the existing technology is too small, and it is very easy to get blocked when taking out. It can only be pushed out by tools, causing the soil sample to deform and the position of the deep soil sample to change, affecting the accuracy of the soil sample analysis results. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problem that the diameter of the sampler of some sampling devices in the prior art is too small, which is very easy to get blocked when taking out and can only be pushed out by tools, causing the soil sample to be deformed and the position of the deep soil sample to change, affecting the accuracy of the soil sample analysis results, and to propose a geological exploration safety sampling device.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a geological exploration safety sampling device, including a sampling assembly, wherein two sampling assemblies are provided, the upper surfaces of the two sampling assemblies are fixedly connected with clamp handles, the two clamp handles are rotatably connected by a rotating shaft, the outer surfaces of the two sampling assemblies are sleeved with a limiting ring, one side surface of the limiting ring is threadedly connected with a bolt, one end of the bolt is rotatably connected to a fixed pressure block through a bearing, and the end of the bolt is fixedly connected to a hexagonal prism.

[0006] Furthermore, one end of one of the pliers handles is fixedly connected to a support block, one side surface of the support block is rotatably connected to a screw rod through a bearing, and one end of the screw rod is threadedly connected to the outer surface of the other pliers handle.

[0007] Furthermore, the other end of the screw rod is fixedly connected to a knob, and the outer surface of the knob is provided with a plurality of grooves at equal intervals.

[0008] Furthermore, two pedals are fixedly connected to the outer surface of the limiting ring, and the two pedals are arranged opposite to each other.

[0009] Furthermore, a limiting slide groove is provided on the inner wall surface of the limiting ring, a limiting slide rail is embedded in the limiting slide groove, and one side surface of the limiting slide rail is fixedly connected to the outer surface of one of the sampling components.

[0010] Furthermore, a size chart is provided on the outer surface of the limiting slide rail.

[0011] Compared with the prior art, the advantages and positive effects of the present invention are:

[0012] 1. In the present invention, when in use, the lower ends of the two sampling assemblies are placed at the sampling location, and then the two sampling assemblies are pressed down. The two sampling assemblies are embedded in the soil to perform sampling operations. After reaching the specified depth, the sampling assemblies together with the soil sample are taken out, and the hexagonal prism is rotated by a wrench so that the bolt drives the fixed pressure block to separate from the sampling assembly, and then the limit ring is removed. Then, the two ends of the pliers handles are separated, so that the two sampling assemblies are opened after being subjected to force, and the soil sample is completely taken out to ensure the integrity of the sampling and the accuracy of the analysis results.

[0013] 2. In the present invention, by rotating the knob, one end of the screw rod is threadedly connected to the surface of one side of the clamp handle, and the two clamp handles are fixed to prevent the clamp handles from being subjected to force to open the two sampling components during transportation. The multiple grooves on the outer surface of the knob increase the friction force. By stepping on the two pedals, the limit ring and the fixed pressure block drive the two sampling components to be inserted into the soil, which is convenient for force generation and improves the user experience. The limit slide groove and the limit slide rail cooperate to limit the moving trajectory of the limit ring, prevent the limit ring from rotating, and ensure stable fit of the components. The height of the limit ring can be intuitively adjusted through the size chart to meet the sampling depth requirements. BRIEF DESCRIPTION OF THE DRAWINGS
