Description

Technical Field

[0001] The invention relates to the technical field of ore mining, in particular to a core drilling sampling device for ore mining. Background Art

[0002] Before ore mining, it is necessary to obtain samples of underground rocks and soil layers through core drilling sampling devices. By analyzing and evaluating these samples, information such as the type, distribution, and reserves of mineral resources can be discovered, providing a basis for mineral development.

[0003] The existing core drilling sampling device usually uses a lifting mechanism and a motor to drive a sampling drill barrel to drill and sample the rock formation. However, it is troublesome to remove the core from the borehole. The sampling drill barrel needs to be inserted into the borehole and taken out multiple times before all the cores can be taken out. This is troublesome and increases the work intensity of the user. In addition, the overall device is usually moved by a pulley with a brake. There is no positioning mechanism on the device, which makes the device unstable during drilling sampling and affects the sampling efficiency. In addition, the existing device is not provided with a horizontal positioning mechanism, and it is difficult to be horizontal as a whole. The core drilling sampling must be kept vertical, and the verticality deviation of the borehole must not be greater than 0.5%, which has poor practicality. Summary of the invention

[0032] Combined with the above structure, the overall device moves the position through a number of universal pulleys 2, drives the sampling drill barrel 5 to rotate through the motor 4, drives the sampling drill barrel 5 to rise and fall through the lifting mechanism 3, and the sampling drill barrel 5 enters the rock formation through the through hole 101 to perform drilling sampling.

[0033] Combined with Figure 3 The lifting mechanism 3 includes a box body 10 installed on one side of the upper end of the base plate 1, the box body 10 has an opening on one side and a screw 11 is connected to a bearing between the upper and lower walls, a motor 12 driven by the screw 11 is installed on the upper end of the box body 10, a pair of guide rods 13 are vertically fixed between the upper and lower walls of the box body 10, and a slider 14 threadedly connected to the screw 11 and slidably connected to the guide rod 13 is longitudinally slidably connected in the box body 10.

[0034] In combination with the above structure, when the lifting mechanism 3 is used, the motor 2 12 drives the screw 11 to rotate, so that the slider 14 threadedly connected to the screw 11 moves longitudinally under the guidance of the guide rod 13, thereby driving the sampling drill tube 5 to rise and fall.

[0035] Combined with Figure 3 A lifting plate 15 is bolted to the side wall of the slider 14 , the motor 4 is mounted on the upper end of the lifting plate 15 , the output end of the motor 4 passes through the lifting plate 15 and is connected to a chuck 16 , and a plurality of clamping rods 17 are provided on the outer side of the chuck 16 .

[0036] Combined with Figure 4 The upper end of the sampling drill tube 5 is provided with a plurality of entry grooves 502 which are penetrated from the upper end and through which the clamping rod 17 passes.
