A sliding groove 21 is opened on one of the fixed rods 2, and a limiting device 4 is arranged in the sliding groove 21. There is a certain friction between the movable tube 34 and the rotating cylinder 35. When the movable tube 34 rotates, it can drive the rotating cylinder 35 to rotate synchronously, so that the two remain relatively still.

[0023] Specifically, when sampling, the base plate 1 is first placed on the ground to be sampled, and the sampling personnel step on both sides of the base plate 1 with their feet to keep the device balanced. At this time, the operating structure 5 can be used to drive the rotating rod 33 and the spiral blade 36 to rotate. During rotation, the spiral blade 36 drills the lower ground through the drill bit assembly 37. When digging downward, the drilled sample slides along the spiral groove of the spiral blade 36 and is mixed with its outer periphery. After the spiral blade 36 is drilled to a suitable depth, the spiral blade 36 is first preliminarily limited by the limiting device 4, and then the operating structure 5 is adjusted to wrap the outer periphery of the spiral blade 36. The sample can be taken out from the groove of the spiral blade 36 by rotating the operating structure 5 in the opposite direction. When the geological mineral resource exploration sampling device is in use, the stability of the device is maintained by manpower, and rotating the operating structure 5 can achieve a variety of different effects, which is convenient for drilling and taking out samples, and the operation is convenient and labor-saving.

[0024] In order to solve the technical problem that the drilled samples are easily mixed in the side wall of the drill bit and are inconvenient to remove and clean, such as Figure 2 - Figure 4 and Figure 7 - Fig.10As shown, the following preferred technical solutions are provided: the inner walls of the upper and lower ends of the fixed cylinder 31 are provided with a second slide groove 311, the outer walls of the upper and lower ends of the rotating cylinder 35 are embedded with a ball 1 351, and the ball 1 351 is slidably connected in the second slide groove 311; the upper end of the fixed cylinder 31 is provided with a third slide groove 312, and the outer walls of the lower end of the rotating disk 32 are fixedly installed with ball 2 321 on both sides, and the ball 2 321 is slidably connected in the third slide groove 312. Through the arrangement of ball 1 351 and ball 2 321, the rotating cylinder 35 and the rotating disk 32 will not deviate from the track when rotating and the friction force during rotation can be reduced.

[0025] A spiral groove 341 is provided on the outer circumference of the movable tube 34, and a spiral plate 39 is rotatably installed in the spiral groove 341. A cleaning structure 38 is provided at the connection between the movable tube 34 and the spiral blade 36. A card slot 1 391 is provided on the spiral plate 39. The cleaning structure 38 includes a cleaning block 381 slidably connected to the spiral blade 36. A slide groove 4 382 is provided in the cleaning block 381, and a movable block 383 is slidably installed in the slide groove 4 382. A pull ring 384 is fixedly installed on the side wall of the movable block 383. A card slot 2 332 is provided on the rotating rod 33. The two ends of the movable block 383 are slidably connected in the card slot 1 391 and the card slot 2 332 respectively. The cleaning block 381 has the same cross-sectional width and height as the spiral blade 36, and can slide along the groove between the spiral blades 36. When sliding, the sample remaining between the spiral blades 36 can be pushed downward along the groove to clean the spiral blade 36.

[0026] A slide groove five 352 is provided on the side wall of the rotating drum 35, and slide grooves six 353 are provided on the inner walls on both sides of the slide groove five 352. A connecting block 393 is fixedly installed on the outer wall of the spiral plate 39, and the connecting block 393 is slidably connected in the slide groove five 352. Ball bearings three 394 are embedded in the upper and lower ends of the side walls on both sides of the connecting block 393, and the ball bearings three 394 are slidably connected in the slide groove six 353. The spiral plate 39 can slide along the slide groove five 352 through the arrangement of the ball bearings three 394 and the connecting block 393.

[0027] The drill bit assembly 37 includes a connecting plate 371 fixedly mounted on one end of the rotating rod 33 , a threaded rod 372 is threadedly connected to the lower end of the connecting plate 371 , a conical drill bit 373 is fixedly mounted on the lower end of the threaded rod 372 , and an opening 374 is opened on the connecting plate 371 .

[0028] The inner walls of the upper and lower ends of the sampling hole 11 are respectively embedded with ball four 12 and ball five 13, and the outer wall of the spiral blade 36 is provided with a connecting groove one 361, and ball four 12 and ball five 13 are slidably connected in the connecting groove one 361. The inner wall of the upper end of the spiral blade 36 is provided with a connecting groove two 362, and the opening 374 is provided at one end of the connecting groove two 362. The lower end of the spiral plate 39 is fixedly installed with a guide rod 392, and the guide rod 392 is slidably connected in the connecting groove two 362. The spiral plate 39 can slide along the connecting groove two 362 through the guide rod 392. When the spiral blade 36 rotates, ball four 12 first slides along the connecting groove one 361. At this time, the spiral blade 36 can be guided by ball four 12 to drill downward. The setting of ball five 13 is to keep the spiral blade 36 drilling vertically downward.

[0029] Specifically, when sampling is carried out through the device, in the initial state, the operating structure 5 can drive the middle rotating rod 33 and the movable tube 34 to rotate together, and drive the spiral blade 36 at the lower end to rotate. The spiral blade 36 cooperates with the connecting groove 1 361 of the side wall and the ball 4 12 so that when the spiral blade 36 rotates, it can drill into the ground below at the same time. The ball 5 13 can keep the spiral blade 36 drilling vertically downward. During the downward drilling process, the sample enters the groove of the spiral blade 36. When drilling downward to a suitable depth, the operating structure 5 can be adjusted to the position where the middle rotating rod 33 cannot rotate. The operating structure 5 can drive the rotating drum 35 to rotate again. When the rotating drum 35 rotates, it can drive the spiral plate 39 to slide along the slide groove 5 352 through the connecting block 393. The spiral plate 39 rotates downward along the spiral groove 341 at the same time. When the spiral plate 39 rotates, the outer periphery of the groove of the spiral blade 36 is The spiral blade 36 and the spiral plate 39 are then adjusted to their initial positions, and the operating structure 5 is then adjusted to a state where the spiral blade 36 in the middle cannot rotate. At this time, the pull ring 384 can be pulled outward to make one end of the movable block 383 stuck in the card slot 1 391. At this time, the operating structure 5 can be rotated again to make the cleaning block 381 slide downward along the groove of the spiral blade 36 when the spiral plate 39 rotates. During the sliding process, the sample mixed in the groove of the spiral blade 36 can be squeezed out. This operation can remove the sample and clean the groove of the spiral blade 36. When the device is in use, the rotatable part inside the sampling device 3 can be controlled by the operating structure 5, and the sample can be drilled and the groove of the spiral blade 36 of the device can be cleaned by alternating forward and reverse rotations.

[0030] In order to solve the technical problem that when the drill bit is pulled out of the sampling surface during drilling, the sample is easily dropped, resulting in a small amount of sampling, such as Figure 1 - Figure 6As shown, the following preferred technical solution is provided: the operating structure 5 includes a connecting rod 51 slidably installed in the turntable 32, a fixed block 52 is fixedly installed at one end of the connecting rod 51, and a handle 53 is fixedly installed on the fixed block 52. When the handle 53 is rotated, the turntable 32 can be driven to rotate through the connecting rod 51.

[0031] The connecting rod 51 is provided with a chute 54, and both side walls of the chute 54 are provided with inclined grooves 55. A movable block 57 is slidably installed in the chute 54, and both sides of the movable block 57 are fixedly installed with a slide rod 58, and the slide rod 58 is slidably connected in the inclined groove 55. A slot 354 is provided at the upper end of the rotating drum 35, and the movable block 57 is slidably connected in the slot 354. The outer periphery of the rotating rod 33 is provided with slots 431 at equal intervals, and a protrusion 56 is fixedly installed at one end of the connecting rod 51. The protrusion 56 is slidably connected in the slot four 331. When the connecting rod 51 is pulled out from the turntable 32, the protrusion 56 can be disengaged from the slot four 331. At this time, the rotation of the connecting rod 51 will not drive the rotating rod 33 to rotate. When the connecting rod 51 is pulled outward, the movable block 57 can be driven to slide along the slide groove seven 54 and the slot three 354 through the inclined groove 55. At this time, the connecting rod 51 can drive the rotating drum 35 to rotate, thereby realizing the replacement of the movable mechanism inside the sampling device 3.

[0032] The limiting device 4 includes a slider 41 slidably mounted on the fixed rod 2, an adjusting rod 42 is threadedly connected to the slider 41, a stop block 43 is fixedly mounted on one end of the adjusting rod 42, the adjusting rod 42 is slidably connected in the slide groove 21, the stop block 43 is in contact with the spiral blade 36, and the spiral blade 36 can be initially limited by the stop block 43 pressing against the outer surface of the spiral blade 36.

[0033] Specifically, when sampling, the movable part in the sampling device 3 can be adjusted by adjusting the position of the connecting rod 51 according to current needs. When it is necessary to drill the lower end, the protrusion 56 at one end of the connecting rod 51 is stuck in the four grooves 331 set on the outer periphery of the rotating rod 33. At this time, by rotating the connecting rod 51, the rotating rod 33, the movable tube 34, the spiral blade 36, the drill bit assembly 37, etc. can be driven to drill downward at the same time. When the spiral blade 36 is drilled to the ground to a suitable sampling depth, the connecting rod 51 is pulled outward to make the protrusion 56 disengage from the four grooves 331. At this time, the protrusion 56 will not drive the rotating rod 33 to rotate when it rotates, and it will drive the movable tube 34 to rotate when the connecting rod 51 slides outward. The block 57 slides obliquely downward along the inclined groove 55 into the card slot three 354 through the slide rod 58. At this time, the connecting rod 51 and the rotating drum 35 can rotate synchronously through the movable block 57, and the spiral plate 39 can be rotated along the concave surface of the spiral blade 36 and fit therewith. After the preliminary drilling is completed, the limit device 4 can be adjusted to a suitable height by sliding the slider 41 to limit the outer side of the spiral blade 36 to keep it still. When the device is in use, the movable part of the device can be switched according to needs. Through the linkage between the operating structure 5 and the sampling device 3, the drilled sample can be completely removed after the drilling is completed, preventing the sample from falling during the removal process.

[0034] In order to better illustrate the above embodiment, the present invention also proposes another technical solution: a geological mineral resource exploration sampling method, comprising the following steps: S1: Preparation work before sampling: first determine the ground to be sampled, level the ground to be sampled with tools, and place the base plate 1 on the ground to prepare for sampling; S2: Drilling and sampling: The sampling personnel step on both sides of the bottom plate 1, step on the bottom plate 1, hold the handle 53 and drive the turntable 32 to rotate through the connecting rod 51. When the turntable 32 rotates, it drives the middle rotating rod 33 to rotate. The rotating rod 33 drives the movable tube 34, the spiral blade 36 and the drill assembly 37 to rotate. When the spiral blade 36 rotates, it slides along the ball 4 12 through the connecting groove 1 361 and drills downward. When the spiral blade 36 rotates downward, the connecting groove 1 361 slides along the ball 5 13 at the same time. At this time, the soil can be drilled to the hollow part in the middle of the spiral blade 36; S3: Sealing the sample: After the drilling sample is completed, the connecting rod 51 can be pulled outward. When the connecting rod 51 moves, it drives the movable block 57 to slide into the third card slot 354. At this time, the connecting rod 51 slides away from the rotating rod 33. The handle 53 is turned again to drive the rotating drum 35 to rotate through the movable block 57. The rotation of the rotating drum 35 drives the spiral plate 39 on the outer periphery to rotate and slide along the spiral slot 341. Under the cooperation between the connecting block 393, the ball bearing three 394, the slide slot five 352 and the slide slot six 353, the spiral plate 39 can slide downward into the spiral slot of the spiral blade 36 during rotation to seal the sampled sample; S4: Collecting samples: Push the connecting rod 31 into the second slide groove 311, and then turn the handle 53 in the opposite direction. The handle 53 can drive the spiral plate 39 to move downward, wrapping the collected soil and the outer periphery of the spiral blade 36, and then pull the connecting rod 31 outward to a position where the rotating drum 35 can be driven to rotate. Turn the handle 53 to lift the spiral blade 36, the spiral plate 39 and the collected soil upward together. At this time, push the connecting rod 31 again to a position where the rotating rod 33 can be driven, and turn the handle 53 forward to rotate the spiral blade 36 again to separate from the spiral plate 39, and then take out the sample between the spiral blades 36; S5: Cleaning device: After taking the sample out from between the spiral blades 36, the pull ring 384 can be pulled outward until the movable block 383 is stuck in the card slot 391. At this time, the cleaning block 381 can move together with the rotation of the spiral plate 39. The connecting rod 31 at the upper end is adjusted to the position of the rotatable spiral plate 39.
