Technical Field

[0002] "Geological exploration" is a survey and research activity that uses various means and methods to survey and detect geology, determine the appropriate bearing layer, determine the foundation type based on the bearing capacity of the bearing layer, and calculate the foundation parameters. Currently, handheld drilling sampling is one of the commonly used exploration techniques in geological exploration. The shallow rock and soil samples obtained by drilling down with a sampler can be used to study the geological structure extending from the stratum.

[0003] The existing handheld drilling sampling equipment can basically meet the sampling needs of shallow rock and soil samples, but there are still certain defects: when the sampling tube is drilling downward for sampling, it is often necessary to manually press the sampling tube downward, which is relatively laborious and causes relatively high fatigue strength for workers. In addition, during the downward drilling sampling process, rock and soil at different depths will adhere to the sampling tube, making it difficult to sample rock and soil at different depths as needed, and the sampling effect needs to be improved. Based on this, the utility model provides a geological exploration drilling sampling equipment. Utility Model Content

[0004] The technical problem solved by the utility model is that: it is often necessary to press the sampling tube downwards manually, which is relatively laborious when sampling, and the fatigue strength of the workers is relatively large. In addition, rock and soil of different depths will adhere to the sampling tube, making it difficult to sample rock and soil of different depths as needed, and the sampling effect needs to be improved.

[0008] Furthermore, the second electric push rod is arranged in a cavity formed between the partition plate and the inner wall of the sampling tube, and the output end of the motor passes through the bottom of the motor box and is fixedly connected to the top of the sampling rod.

[0009] Furthermore, the inner side wall of the sampling tube is symmetrically provided with slide rails matching the side wall of the plug.

[0010] Furthermore, the top of the top plate is symmetrically provided with handles placed on both sides of the electric push rod.

[0011] Furthermore, soil dividing teeth are provided on the circumference of the bottom of the sampling tube.

[0012] Beneficial effects of the utility model:

[0013] The controller is used to start the electric push rod 1 to drive the motor box, the sampling rod and the sampling barrel to move downward, and the controller is used to start the motor to drive the sampling rod and the sampling barrel to rotate, so that the sampling barrel rotates while moving downward. When the sampling barrel drills to a suitable depth in the shallow layer, the controller is used to start the electric push rod 2 to drive the plug to move downward, so that the soil storage space inside the sampling barrel is exposed, so as to sample the rock and soil. Compared with traditional shallow rock and soil sampling equipment, there is no need to manually press the sampling barrel downward, and the sampling of shallow geological rock and soil can be quickly achieved. Sampling is more labor-saving and reduces the fatigue intensity of workers.
