[0002] Geological prospecting is the abbreviation of geological exploration work, which mainly involves the exploration and detection of geology through various means and methods, determining the appropriate bearing layer, and determining the foundation type according to the bearing capacity of the bearing layer, and calculating the foundation parameters. It is the corresponding technical mode and effective means adopted to discover various mineral resources. It conducts detailed exploration and detection of the specific geological conditions in a certain area. Geological exploration is of great significance in resource development, environmental protection, engineering construction, disaster prevention and mitigation, scientific research, and social and economic development. With the continuous advancement and application of science and technology, geological exploration technology is also constantly updated and improved, providing strong support for the sustainable development of mankind. In geological exploration, it is necessary to test the soil at the exploration site, so it is necessary to sample the soil at the exploration site.

[0003] However, the existing soil sampling method is to drill out the soil with a drill bit and then sample the soil through a soil sampling tube. However, this method will destroy the structure of the soil layer, which is not conducive to the later soil detection, and the inner wall of the soil sampling tube will be attached with soil, which is not convenient for cleaning.

[0004] In view of this, the present utility model is proposed. Utility Model Content

The device has the advantages of intact soil layer preservation and convenient use. The servo motor drives the soil sampling barrel to rotate through the active bevel gear and the driven bevel gear ring. The soil layer can be cut under the action of the cutting serrated ring. Then the motor is controlled to drive the lifting threaded rod to rotate, so that the soil sampling barrel can be driven to move downward through the lifting plate, so that the soil sampling barrel can penetrate into the soil. Then the soil sampling barrel is reset to complete sampling. The push plate can push the soil sample out of the soil sampling barrel, which is convenient for detection and can clean the inner wall of the soil sampling barrel at the same time.

When in use, the utility model is first placed at the use location, and then the soil sampling barrel is rotated and driven downward by the automatic lifting component until it moves into the soil layer. At this time, the soil sample will be located in the soil sampling barrel, and then the soil sampling barrel is reset to complete the soil sampling.

[0007] Furthermore, in order to fix the utility model at the place of use, fixing rods are fixedly installed at the four corners of the lower end of the base plate, and the lower ends of the fixing rods are tapered.

[0008] Furthermore, in order to install the automatic lifting component on the top plate, the automatic lifting component includes a slow-speed control motor, which is fixedly mounted on both sides of the upper end of the top plate and located on both sides of the through hole.

[0009] Furthermore, in order to drive the lifting threaded rod to rotate, a lifting threaded rod is fixedly installed at the output end of the slow control motor, and the other end of the lifting threaded rod passes through the top plate and is rotatably clamped on both sides of the upper end of the bottom plate.

[0010] Furthermore, in order to drive the lifting plate to rise and fall, the automatic lifting assembly also includes a lifting plate, the lifting plate is slidably clamped on the guide support rod, and the lifting plate is threadedly sleeved on the lifting threaded rod, and the clamping ring is fixedly installed in the middle position of the lifting plate.

[0011] Furthermore, in order to drive the soil sampling barrel to rotate, thereby cutting the soil layer and improving the integrity of the sampling, a driven conical gear ring is fixedly installed on the outer side of the soil sampling barrel, and the driven conical gear ring is located below the clamping ring. A servo motor is fixedly installed on one side of the lower end of the lifting plate, and an active conical gear is fixedly installed on the output end of the servo motor, and the active conical gear is meshed with the driven conical gear ring.

The lower end of the connecting rod is fixedly connected to the upper end of the push plate, and the upper end of the connecting rod is located above the limit plate.

[0014] The technical effects and advantages of the utility model are as follows: the soil sampling barrel can be lifted and lowered by the automatic lifting component, and the soil sampling barrel can be rotated at the same time, so that the soil layer can be cut by the cutting sawtooth ring, so that the soil sampling barrel can be penetrated into the soil layer, and then the soil sampling barrel can be taken out to complete the soil sampling, and then the push plate can push the soil sample out of the soil sampling barrel, so as to avoid the soil adhering to the inner wall of the soil sampling barrel and facilitate cleaning.
