Technical Field

[0001] The utility model relates to the technical field of mining exploration, in particular to an underground sampling device for mining exploration. Background Art

[0002] Mining exploration refers to the geological work carried out by using various means and methods to survey and detect concentrated areas of ore after determining the ore deposits with industrial value, in order to provide reliable ore reserves and necessary geological, technical and economic data for mine design. Generally, sampling is carried out in the survey area through sampling devices.

[0003] The patent document with the announcement number CN214251629U discloses an underground sampling device for mining exploration, including a frame, a motor is fixedly installed on the top of the frame, and a first push rod motor is fixedly installed on both sides of the top of the inner cavity of the frame. The utility model starts the motor to drive the drill bit to rotate through the arrangement of the motor, the first push rod motor, the second push rod motor, the sampling tube, the drill bit and the baffle, and then starts the second push rod motor to drill a hole on the ground, so that there is a large amount of slag in the hole, and then starts the first push rod motor to push the sampling tube to the upper side of the inside of the hole, and then starts the second push rod motor to pull the drill bit to move upward. Since the size of the drill bit is larger than the size of the sampling tube, the slag in the hole is pushed into the sampling tube through the top of the drill bit, so that all the coal in the hole can be brought out of the ground at one time, and it is not necessary to take samples multiple times to obtain more coal, which further improves the work efficiency, but the prior art still has defects:

[0004] (1) The sampling device of the prior art is large in size and inconvenient to move, which brings inconvenience to coal mine sampling in narrow areas. In addition, the stability of the device is average when sampling, and the device samples minerals at different depths at the same time.

[0005] (2) The sampling device of the prior art can only take samples once, and then the sampling tube needs to be pulled out, the sample needs to be taken out and then re-sampled. It is not possible to achieve multiple intermittent sampling during the insertion process. At the same time, the mineral samples need to be collected manually after sampling. At the same time, the mineral samples are easily scattered when they are taken out of the sampling tube, which increases the labor intensity of the staff and reduces the practicality of the device.
