[0024] The following is combined with Figure 1-4 , the technical solution of the utility model is further explained:
[0025] like Figure 1 and Figure 2 As shown, a coal mine geological exploration sampling device includes an operating handle 1, a power source is installed on the upper part of the operating handle 1, a drill rod 3 with threads on the outer circumference that can be driven to rotate by the power source is movably arranged on the lower part of the operating handle 1, and a drill bit 4 is detachably arranged on the lower part of the drill rod 3.

[0026] Specifically, Figure 4 As shown, the drill rod 3 includes a plurality of arc-shaped connecting sections 31, on which protrusions and grooves are provided, and the protrusions 33 on the arc-shaped connecting sections 31 are inserted into the grooves in the adjacent arc-shaped connecting sections 31. In other words, the drill rod is formed by overlapping and assembling four arc-shaped connecting sections, each of which is provided with a protrusion and a groove. During assembly, the protrusions on the arc-shaped connecting sections are placed in the grooves on the adjacent arc-shaped connecting sections, and the protrusions are connected in sequence, thereby completing the assembly of the drill rod. During subsequent soil excavation, the drill rod can be removed as a whole and transported separately.
[0027] Furthermore, if Figure 3As shown, the first limit segment 32 and the second limit segment are respectively provided at both ends of the arc-shaped connecting segment 31, and the first limit segment 32 is inserted into a linkage member movably provided on the operating handle 1, and the linkage member is connected to the power source; that is, the first limit segment and the second limit segment are respectively provided at the top and the bottom of the arc-shaped connecting segment, and during assembly, the various arc-shaped connecting segments are first overlapped into a drill rod, and then the first limit segments at the top of the arc-shaped connecting segment are respectively inserted into the linkage members on the operating handle.
[0028] The adjacent second limiting section integrally forms a threaded connector 8 for mounting a drill bit. In other words, the connector formed by the second limiting section can be tightened and reinforced by using a drill bit.
[0029] It should be noted that if Figure 1 As shown, the drill bit 4 is provided with threads on the periphery and inside, a soil taking opening is provided at the bottom of the drill bit 4, and the overall cross-sectional shape of the drill bit is trapezoidal. That is, threads are provided on the periphery and inside of the drill bit, respectively, and the drill bit is screwed into the connector at the bottom of the drill rod, which can reinforce the bottom of the drill rod. At the same time, the drill bit and the drill rod are integrally provided with guide threads, which helps to drill into the stratum more easily.

[0032] Specifically, Figure 2As shown, the drill rod 4 is provided with a sampling mechanism that can push out the sampled soil layer; the operating handle 1 is provided with a control panel for controlling the power source and the start and stop of the sampling mechanism. That is to say, when collecting soil samples for coal mine geological exploration, by pressing the button on the control panel on the operating handle, the power source can be controlled to start drilling into the stratum to collect soil. After the soil sample is collected, the entire device is taken out of the stratum, and then the control button on the control panel is clicked, and the sampling mechanism set in the drill rod can quickly push out the accumulated soil in the drill rod, avoiding the soil sample from being stuck in the drill rod and being difficult to remove.
