Problems solved by technology

[0002] With the continuous development and progress of the highway transportation industry, the condition of the foundation soil layer in the highway project is directly related to the construction quality of the highway. 800 mm subgrade soil samples were analyzed to ensure the construction quality of the highway. In the prior art, the soil sampling device used in highway engineering is mainly a twist drill composed of a drill shank, a drill pipe and a spiral drill bit. However, it uses When collecting soil for highway projects, the operation is cumbersome, time-consuming and laborious. The soil sampling device will mix each layer of soil during the soil sampling process, and the soil samples taken are all broken soil samples, which destroys the structure of the original soil sample layer and leads to testing. The error of the result is very large, which reduces the accuracy of the experimental result

Abstract

The invention discloses a soil sampling device for soil quality identification. The soil sampling device comprises a fixed base, a soil drilling device and soil loading devices. A free end of a pistonrod in a hydraulic cylinder is connected to the soil drilling device. The soil drilling device comprises an electric motor 1, a rotating shaft and a drill bit. The soil loading device comprises a lifting device and a sampling container. The lifting device comprises a motor 2, a worm wheel and a worm rod. The worm wheel is meshed with the worm rod. The lower end of the worm rod is connected to a fixing block through a bearing. The soil sampling device can acquire samples from a soil sample layer at the same sampling point at different depths. Through the three soil loading devices, the soil sampling device can acquire samples from a soil sample layer at the same sampling point at different depths, initially distinguish the soil quality of the soil layer, ensure the integrity of the obtained soil layer structure, reduce the errors caused by sampling and improve the accuracy of the experimental results.
