Description

Technical Field

[0001] The utility model relates to the field of rock and soil exploration, in particular to a rock and soil exploration drilling sampling device. Background Art

[0002] Geotechnical engineering is the study of solving rock and soil engineering problems, including foundations, slopes and underground engineering. Geotechnical drilling sampling devices are used to collect and extract rock and soil from the surface of the soil in the natural environment, so that relevant personnel can analyze the composition of the soil and determine whether the soil area is suitable for construction. However, the current geotechnical exploration drilling sampling structure is generally fixed directly at the required position for drilling and sampling. When the rock and soil are sampled, the equipment needs to be moved to analyze and process the extracted rock and soil. However, this equipment needs to be manually moved to unload the rock and soil, which is very laborious and reduces its sampling efficiency.

[0003] Chinese patent application number 202321409708.3 discloses a rock and soil exploration drilling sampling device, comprising two symmetrically placed support rods, a support frame assembly is installed on the top surface of the support rods, a drilling sampling tube with an inner cavity having a spiral drill is longitudinally provided in the middle position of the support frame assembly, and a detachable end cover is installed at the bottom of the drilling sampling tube, which is not only convenient for drilling and sampling of rock and soil, but also convenient for unloading and dust removal of sample rock and soil, thereby replacing the unloading method of handling equipment and improving its exploration drilling sampling efficiency. The above scheme has the following defects: a rotating motor drives the drilling sampling tube to rotate, and rock and soil enter the drilling sampling tube through the soil inlets on both sides. By removing the detachable end cover, the sampled rock and soil smoothly enters the sample tray. The end cover is arranged on the outside of the sampling tube. When sampling rocks, the end cover is easily damaged, and the end cover needs to be frequently removed during the sampling process, which is cumbersome to operate and inconvenient to use.

[0004] Therefore, a rock and soil exploration drilling sampling device is provided to solve the above problems. Utility Model Content
