AI Technical Summary
Existing soil sampling drilling rigs cannot operate continuously during the sampling process. The sampling tube must be lifted from the ground before soil samples can be collected, resulting in high labor intensity and low efficiency for operators.
A soil sampling drill was designed, comprising a mobile carrier, a lifting frame, a drilling assembly, and a sampling assembly. The drilling shaft contacts the ground and rotates through a hydraulic push rod and a motor drive. Soil is transported to the discharge port through a spiral blade, and the soil is screened by a screening cylinder. Soil that meets the requirements is sent into the sample tank.
This enabled continuous sampling during drilling, improving the efficiency of soil sampling and reducing the labor intensity of operators.

Abstract
Description
Technical Field
[0001] This invention relates to the field of energy-saving mining machinery and equipment technology, specifically a soil sampling drill. Background Technology
[0002] In mine soil exploration, in order to obtain the physical and mechanical properties of foundation soil, it is sometimes necessary to take original soil samples from deeper depths. Soil sampling drills are used to lift the original soil samples from the lower test soil layer to understand its properties, so as to gain a better understanding of the properties of the base layer.
[0003] A search revealed a Chinese patent with publication number CN215949352U that discloses a soil sampling drill. During soil sampling, the drill base is fixed to the sampling position, the drive mechanism is activated to rotate the rotating sleeve, and then the lifting assembly is activated to move the sampling tube closer to the ground. Once the sampling tube successfully retrieves soil, the lifting assembly pushes the sampling tube with soil further away from the ground to complete the soil sampling. During the sampling and sample retrieval process, the operator does not need to manually move the sampling tube, reducing the operator's workload. However, the sampling tube must be lifted from the ground before a soil sample can be taken, making continuous sampling during the drilling process impossible.
[0004] Therefore, we propose a soil sampling drill. Summary of the Invention
