DETAILED DESCRIPTION

[0028] The technical scheme in the embodiments of the present application will be described clearly and completely in the following by combining with the drawings in the embodiments of the present application, obviously, the described embodiments are only some embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the ordinary skilled in the art without creative labor are within the scope of protection of the present application.

[0030] Please refer to Figures 1 to 3 The utility model discloses a sampling device for resource exploration, including bottom plate 1 and crossbeam 4, bottom plate 1 is round board, rectangular plate or is the cross structure shown in the embodiment, and the through hole for sampling is set up in the center of bottom plate 1.

[0031] As Figures 4 to 5 The upper surface of bottom plate 1 is fixedly connected with two oppositely arranged stand columns 2, and is rotatably connected with two vertically arranged lead screws 3. The two stand columns 2 are symmetrically arranged relative to the through hole, and the stand column 2 is provided with a sliding groove 201, which can be a T-shaped groove structure, and the lead screw 3 is located in the sliding groove 201.

[0032] As Figure 6 The two ends of crossbeam 4 are connected with sliding blocks 401 matched with the sliding grooves 201, and the middle position of crossbeam 4 is rotatably connected with a drill rod 5 and two rotation shafts 6 symmetrically arranged relative to the drill rod 5. The sliding block 401 is rotatably connected with a nut 301 matched with the lead screw 3 through a bearing, and the outer wall of the nut 301 is fixedly connected with a transmission wheel 302.

[0033] The upper end of the drill rod 5 penetrates through the crossbeam 4, and is fixedly connected with a driving wheel 501 and is drivingly connected with a driving device 502 connected with the crossbeam 4 through a shaft coupling. The driving device 502 is a motor connected with the crossbeam 4 through a mounting bracket.

[0034] The rotation shaft 6 is fixedly connected with a driven wheel 601 engaged with the driving wheel 501 and a transition wheel 602 drivingly connected with the transmission wheel 302, and the transmission wheel 302 and the transition wheel 602 are synchronous pulleys drivingly connected with each other through a synchronous belt.

[0035] When sampling, the drill rod 5 is driven to rotate by the driving device 502, and the rotation shaft 6 is driven to rotate by the driving wheel 501 and the driven wheel 601, and then the transition wheel 602 and the transmission wheel 302 are driven to rotate, driving the nut 301 to rotate, thereby synchronously driving the two nuts 301 to rotate, realizing the up-down movement of the crossbeam 4.

[0036] So that the drill rod 5 moves downward during rotation to drill and sample. The transmission ratio between the driving wheel 501 and the driven wheel 601 is greater than 1, so that the rotational speed of the shaft 6 is reduced when the drill rod 5 has a higher rotational speed, so that the rotational speed of the nut 301 is reduced, thereby reducing the moving speed of the cross beam 4, avoiding excessive feeding speed when drilling.

[0037] Meanwhile, the transmission ratio between the transition wheel 602 and the transmission wheel 302 is greater than 1, so that the rotational speed of the nut 301 is further reduced, that is, the speed of the cross beam 4 moving downward with the drill rod 5 is reduced, so that the drill rod 5 has a higher rotational speed when drilling, and the feeding speed is smaller, so that it can adapt to drilling and sampling in harder soil layers, and ensure the reliability and stability of sampling.

[0038] As a further optimization, the upright column 2 is provided with a scale 202 on the side surface in the vertical direction, by observing the position of the cross beam 4 corresponding to the scale 202, the up and down moving distance of the cross beam 4 can be determined, so that the sampling depth can be accurately controlled, and the sampling accuracy is improved.

[0039] As shown in Figure 5 and 7 , the bottom plate 1 is also connected with four fixing mechanisms, which are arranged circumferentially relative to the drill rod 5. The fixing mechanism is fixedly connected to the upper surface of the bottom plate 1. Among them, the fixing mechanism includes a chute plate 101 with a cross-section in the shape of a, the chute plate 101 is rotatably connected with a screw 102, and the sliding block 103 is slidably connected.

[0040] The upper end of the screw 102 is fixedly connected with a rotating handle 104, the sliding block 103 is provided with a threaded hole 105 matched with the screw 102, and the ground nail 106 is welded or connected by a screw, for driving the screw 102 to rotate by the rotating handle 104, and driving the ground nail 106 to insert into the ground by the sliding block 103, so that the position of the sampling device is fixed.

[0041] And, as shown in Figure 3 and 5 , the screw 102 is inclined relative to the horizontal plane, the chute plate 101 is also inclined, and is fixedly connected with the bottom plate 1 by a screw, the ground nail 106 is arranged in parallel with the screw 102, and the screw 102 is arranged inclined relative to the horizontal plane, so that the sliding block 103 drives the ground nail 106 to insert into the ground obliquely when moving along the axial direction of the screw 102.

[0042] After the ground nail 106 is inserted into the ground in an inclined attitude, it not only fixes the horizontal position of the sampling device, but also has a better fixing effect on the vertical position, thereby effectively improving the fixing effect of the sampling device and ensuring the stability during sampling.
