[0028] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a complete rock sample collection device of this utility model.

[0029] like Figures 1-6 As shown, this utility model embodiment provides a complete rock sample sampling device, including a sampling box 100 and a sampling unit 200 installed inside the sampling box 100 for drilling and sampling the sample. The lower end of the sampling unit 200 is provided with a spray section 300 for spraying water to reduce dust and cool the target location, and the lower end of the sampling unit 200 is provided with a clamping unit 400 for clamping the rock sample.

[0030] The sampling unit 200 includes a lifting seat 220 for mounting and moving, and a drill bit 240 disposed at the lower end of the lifting seat 220 for drilling and sampling rocks. The drill bit 240 is hollow and has a serrated lower end. The drill bit 240 can be fixedly connected by screws. A first drive motor 230 is installed at the upper end of the lifting seat 220 to drive the drill bit 240 at the lower end to rotate. One side of the lifting seat 220 is slidably installed inside a groove opened on the side of the mounting bracket 210 which is fixedly installed on the other side. Positioning components for support are installed at both the upper and lower ends of the mounting bracket 210. A lifting screw 260 for adjusting the height of the lifting seat 220 is rotatably installed in the middle of the positioning component through a bearing. A second drive motor 270 for adjusting the lifting screw 260 is fixedly installed at the upper end of the lifting screw 260.

[0031] During the sampling process, the first drive motor 230 drives the drill bit 240 installed at the lower end to rotate, thereby drilling a hole in the large rock placed at the lower end for sampling. During sampling, the second drive motor 270 drives the lifting screw 260 installed at the lower end to rotate, thereby driving the drive head 250 to move, which can penetrate and remove cylindrical samples, making it convenient to decompose and sample larger rock samples, and to completely penetrate and sample the rock sample. After the rotation sampling is completed, the drill bit 240 can be removed and the sample can be taken out, which is convenient for analyzing the internal structure of the rock and then analyzing the environment near the formation of the rock.

[0032] The spray unit 300 includes a mounting base 340 for supporting the upper end and a rotating frame 310 movably mounted on the upper end of the mounting base 340 for supporting the whole. The rotating frame 310 is movably mounted on the upper end of the mounting base 340 via bearings. Each upper end of the mounting base 340 is equipped with a water spray nozzle 330 for spraying water. The water spray nozzle 330 is fixedly mounted on the upper end of a fastening frame 320. The fastening frame 320 is movably mounted on one side of the rotating frame 310 via bolts. When it is necessary to drill material sampling at the target location, water can be sprayed through the water spray nozzle 330. The fastening frame 320 movably mounted on one side of the rotating frame 310 can adjust the angle of water spraying, thereby achieving the effects of cooling and dust reduction during sampling, which facilitates sampling.

[0033] The lower end of the rotating frame 310 is fixedly equipped with a mounting head 350 for driving the rotating frame 310 to rotate. One side of the mounting head 350 is connected to the drive cylinder 360 through a movable head. The drive cylinder 360 is supported by the mounting frame at the lower end. When the spray nozzle 330 is working, the drive cylinder 360 can push the mounting head 350 to rotate around the shaft at the lower end of the rotating frame 310, thereby driving the rotating frame 310 installed at the upper end to rotate, and driving the spray nozzle 330 to rotate and swing, increasing the spray area.

[0034] The clamping unit 400 includes a fixed frame 410 for supporting the whole and a movable frame 420 that is movably installed on both sides of the fixed frame 410 and can be adjusted. The movable frame 420 is fitted on the upper end of the fixed frame 410. A clamping head 450 for clamping and fixing the rock sample is movably installed on the inner side of the movable frame 420. During the sampling process, the movable frame 420 pushes the inner clamping head 450 to retract inward to clamp and fix the rock, making it convenient for the sampling unit 200 at the upper end to operate.

[0035] The inner side of the movable frame 420 is provided with a track cylinder 440 for moving the movable frame 420. The upper and lower sides of the fixed frame 410 are fixedly installed with fixed tracks 430 for cooperating with the track cylinder 440. The fixed tracks 430 and the track cylinder 440 are installed together, and the positions of the movable frames 420 on both sides can be easily adjusted through the fixed tracks 430 and the track cylinder 440. The adjustment is convenient.

[0036] The clamping head 450 is provided with four sets arranged symmetrically, and is supported by locking brackets 451 that are movably installed on both sides of the mounting shaft. When clamping, the clamping head 450 rotates to easily conform to the shape of the rock for fixed support.

[0037] The sampling box 100 has a through-hole in the middle of the installation position of the bottom clamping unit 400, and the position of the through-hole matches the position of the drill bit 240, which facilitates through sampling and avoids damaging the bottom of the sampling box 100.

[0038] The working principle of a rock sample integrity sampling device is as follows: During the sampling process, the first drive motor 230 drives the drill bit 240 installed at the lower end to rotate, thereby drilling a hole in the large rock placed at the lower end for sampling. During sampling, the second drive motor 270 drives the lifting screw 260 installed at the lower end to rotate, thereby driving the drive head 250 to move, which can penetrate and remove cylindrical samples, making it convenient to decompose and sample larger rock samples, so as to carry out complete penetration sampling of rock samples. After the rotation sampling is completed, the drill bit 240 can be removed and the sample can be taken out, which is convenient for analyzing the internal structure of the rock and then analyzing the environment near the rock formation.
