[0011] A method for using a mineral geological exploration device comprises the following steps: S1. When in use, start the drilling motor to rotate the drill rod, then the support seat drives the drill rod into the soil, stop the machine when the drill rod is drilled into the appropriate position, and then turn the adjusting rod to rotate the main bevel gear ring synchronously. With the cooperation of the bevel gear rod, the slave bevel gear ring rotates in the opposite direction on the surface of the adjusting rod. At this time, the main bevel gear ring and the slave bevel gear ring move synchronously in opposite directions with the corresponding connecting strips, so that the two arc-shaped partitions move in opposite directions at the position of the sampling slot, so that the sampling slot position is released from the sealing state; S2. When the arc-shaped partition is moving, the L-shaped movable rods on the two arc-shaped partitions move synchronously, so that the upper end of the L-shaped movable rod moves along the L-shaped adjustment groove track on the top surface of the movable chamber, and then the L-shaped movable rod extends from the sampling slot with the scraper and inserts into the inner wall of the borehole. At this time, the scraper moves synchronously with the arc-shaped partition to scrape off the disturbed soil on the inner wall of the borehole; S3. During the movement of the arc partition, the guide pin at the top of the arc partition slides along the arc guide groove track at the bottom of the partition, so that the partition moves between the top of the arc partition and the top surface of the sampling slot. At this time, the partition moves out of the sampling slot and inserts into the inner wall of the borehole to prevent the soil at the upper position of the borehole from falling into the sampling slot. S4. Finally, press the adjustment rod to move the adjustment rod with the gasket and the movable block downward. At this time, the lower parts of the two movable blocks slide in cooperation with the inclined grooves on both sides of the U-shaped movable plate, so that the U-shaped movable plate extends from the sampling slot position with the sampling box through the threaded tube. At this time, the open end of the sampling box is inserted into the soil for sampling. When the sampling is completed, pull the adjustment rod upward. At this time, the sampling box resets and moves. As the sampling box leaves the soil, it resets with the baffle under the action of the torsion spring. At this time, the baffle isolates the sample inside the sampling box and pushes the soil outside the sampling box back into the sampling slot of the drill hole, thereby completing the geological survey sampling operation.

[0012] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, through the coordinated use of components such as the drill rod, the isolation mechanism and the adjusting rod, the adjusting rod is rotated to move downward in coordination with the isolation mechanism, and the two arc-shaped partitions on the adjusting mechanism move back to back and carry the scraper to scrape the inner wall of the borehole, so that the soil falling from the upper position of the borehole is scraped off, effectively reducing the mixing of soil at different depths on the inner wall of the borehole, and improving the quality of soil exploration and sampling.

[0013] In the present invention, by using the arc partition, the isolation plate and the sampling groove and other components in coordination, when the two arc partitions move away from each other, the isolation plate can be moved out from the inside of the sampling groove and inserted into the inner wall position of the borehole to isolate the upper position of the sampling groove, thereby preventing the soil above the borehole from falling during the sampling operation and affecting the soil sampling quality.

[0014] In the present invention, through the coordinated use of components such as the drill rod, the sampling mechanism and the isolation mechanism, when the isolation mechanism releases the seal on the inner wall of the drill rod, the sampling mechanism can be extended from the inside of the drill rod to sample soil at different depths of the borehole. At the same time, the extended sampling box is easy to replace and clean, avoiding the mixing of soil sampled last time inside the sampling box when multiple samplings are required.

It should be noted that the drill rod 3 is rotated by the cooperation of the drilling motor 4 and the synchronous belt 5, and then the support seat 2 slides up and down on the side wall of the support frame 1, and the rotating drill rod 3 is drilled into the soil.

[0019] The middle of the drill rod 3 is vertically movably connected with an adjusting rod 6, and three movable chambers 7 are equidistantly provided inside the drill rod 3. The surface of the adjusting rod 6 is equidistantly movably connected with three sampling mechanisms 8, which are respectively arranged inside the three movable chambers 7. An isolation mechanism 9 that cooperates with the sampling mechanism 8 is movably connected between the inner wall of the movable chamber 7 and the surface of the adjusting rod 6. It should be noted that: the top of the drill rod 3 is fixedly connected with a limit tooth ring, and the upper part of the adjusting rod 6 is fixedly sleeved with a limit gear that cooperates with the limit tooth ring. At this time, the adjusting rod 6 can only be rotated after the adjusting rod 6 is pressed to release the limit tooth ring from cooperating with the limit gear, so as to ensure that the unused adjusting rod 6 can be self-locking.

[0020] The sampling mechanism 8 includes a gasket 801, which is rotatably connected to the surface of the adjusting rod 6, and a movable block 802 is symmetrically fixedly connected to the bottom of the gasket 801. It should be noted that a support bearing is fixedly connected between the inner ring of the gasket 801 and the surface of the adjusting rod 6, so that the gasket 801 will not rotate synchronously with the adjusting rod 6 during rotation, thereby avoiding interference.

[0021] The inner bottom surface of the movable bin 7 is symmetrically fixedly connected with a slide bar 803, the surface of the slide bar 803 is movably sleeved with a return spring 804, the surface of the slide bar 803 is movably sleeved with a slider 805, the tops of the two sliders 805 are fixedly connected with a U-shaped movable plate 806, the concave surface in the middle of the U-shaped movable plate 806 overlaps the surface of the adjustment rod 6, both sides of the U-shaped movable plate 806 are provided with oblique grooves 807, and the lower parts of the two movable blocks 802 are respectively slidably connected inside the two oblique grooves 807. It should be noted that: both ends of the slide bar 803 are fixedly connected with pads, and the slide bar 803 is fixedly connected to the inner bottom surface of the movable bin 7 through the pads.

[0022] A threaded tube 808 is fixedly connected to the left side of the U-shaped movable plate 806, and a sampling box 812 that cooperates with the isolation mechanism 9 is movably connected to the end of the threaded tube 808. A rotating rod 809 is symmetrically rotatably connected to the inside of the left end of the sampling box 812. A baffle 810 is fixedly connected to the middle of the rotating rod 809, and a torsion spring 811 is fixedly connected between the two ends of the rotating rod 809 and the inner wall of the sampling box 812. It should be noted that: the inner top surface of the left end of the sampling box 812 is fixedly connected with a limit block that cooperates with the baffle 810 to prevent the baffle 810 from flipping toward the outside of the sampling box 812; when the sampling box 812 is inserted into the soil, the two baffles 810 are compressed and flipped inward, and the soil enters the interior of the sampling box 812; when the sampling box 812 is pulled out from the soil, the side wall of the baffle 810 is no longer compressed. At this time, the torsion spring 811 flips the baffle 810 and resets it, pushing the excess soil outside the sampling box 812 back into the sampling trough, and isolating the soil inside the sampling box 812 at the same time.

[0023] In this embodiment, Figures 1 to 11As shown, a movable pin is fixedly connected to the lower part of the movable block 802, and the movable block 802 is slidably connected to the inside of the corresponding inclined groove 807 through the movable pin.

[0025] In this embodiment, Figures 1 to 11 As shown, a screw is fixedly connected to one side of the sampling box 812 near the threaded tube 808, and the sampling box 812 is threadedly connected to the threaded tube 808 through the screw, and the left end of the sampling box 812 is set as an inclined surface. It should be noted that: through the setting of the inclined surface, the right end of the sampling box 812 can be effectively inserted into the soil for sampling operations; when the threaded tube 808 moves to the extreme position in the direction of the sampling groove 901, the sampling box 812 can be extended from the inside of the drill rod 3, ensuring that the sampling box 812 can effectively perform geological survey sampling, and at the same time, it is convenient to take out the sampling box 812 from the inside of the drill rod 3 for replacement later.

It should be noted that the bottom of the slave bevel gear ring 905 overlaps the top of the gasket 801, and the sampling box 812 is arranged at the lower position of the sampling slot 901, so that the sampling box 812 can extend from the sampling slot 901.

[0027] The inner ring of the main cone gear ring 904 is slidably connected to the surface of the adjustment rod 6, and the side walls of the main cone gear ring 904 and the secondary cone gear ring 905 are fixedly connected with a connecting strip 906, and one end of the two connecting strips 906 is fixedly connected with an arc partition 907, and the two arc partitions 907 are symmetrically arranged at the inner wall position of the sampling through groove 901, and the bottom of the arc partition 907 is slidably connected to the inner bottom surface of the movable bin 7. It should be noted that: a positioning arc groove is provided at the bottom of the arc partition 907, and a positioning pin matching the positioning arc groove is fixedly connected to the inner bottom surface of the movable bin 7 to ensure that the arc partition 907 slides stably inside the movable bin 7; the two arc partitions 907 can properly seal the sampling through groove 901.

[0028] An isolation plate 908 is overlapped between the tops of the two arc-shaped partitions 907, and the top of the isolation plate 908 overlaps the inner top surface of the sampling slot 901. The bottom of the isolation plate 908 is symmetrically provided with an arc-shaped guide groove 909. The tops of the two arc-shaped partitions 907 are fixedly connected with guide pins 910, and the two guide pins 910 are respectively slidably connected inside the two arc-shaped guide grooves 909. It should be noted that: the end of the isolation plate 908 away from the adjustment rod 6 is set as an inclined surface; when the two arc-shaped partitions 907 move back to back during the sampling operation, in the process of the coordinated sliding of the arc-shaped guide groove 909 and the guide pin 910, the isolation plate 908 extends from the inside of the sampling slot 901 and is inserted into the inner wall position of the borehole through the inclined surface, isolating the upper position of the sampling slot 901 to prevent the soil at the upper part of the borehole from falling into the sampling slot 901.

[0029] A groove 911 is formed on opposite sides of the two arc-shaped partitions 907 . A scraper strip 912 is slidably connected inside the groove 911 . An L-shaped movable rod 913 is fixedly connected to one side of the scraper strip 912 close to the groove 911 .

[0030] The inner top surface of the movable bin 7 is symmetrically provided with L-shaped adjustment grooves 914, and the two L-shaped adjustment grooves 914 correspond to the two L-shaped movable rods 913 one by one, and one end of the L-shaped movable rod 913 penetrates the arc partition 907 and is slidably connected to the inside of the corresponding L-shaped adjustment groove 914. It should be noted that: during the drilling process, the soil on the upper part of the inner wall of the borehole will slide down along the gap position and adhere to different depth positions of the borehole. When the arc partition 907 moves, it moves synchronously with the L-shaped movable rod 913. At this time, the L-shaped movable rod 913 slides along the track of the L-shaped adjustment groove 914, so that the L-shaped movable rod 913 extends from the inside of the groove 911 with the scraper 912. The extended scraper 912 moves with the arc partition 907 and scrapes the disturbed soil on the inner wall of the borehole; the cross section of the scraper 912 is set to be trapezoidal, which is convenient for scraping the soil.

It should be noted that: the isolation plate 908 can stably translate between the inner top surface of the sampling slot 901 and the top of the arc-shaped partition plate 907 through the sliding cooperation of the transverse groove and the transverse pin.

[0034] In this embodiment, Figures 1 to 11 As shown, a transmission groove is provided on the side wall of the support frame 1, a transmission screw is rotatably connected inside the transmission groove, a screw sleeve is threadedly connected to the upper part of the transmission screw, the surface of the screw sleeve is fixedly connected to the side wall of the support seat 2, and the side wall of the screw sleeve is slidably connected to the side wall of the transmission groove.

[0035] The top of the support frame 1 is fixedly connected with a transmission motor, and the rotating end of the transmission motor is fixedly connected with the top of the transmission screw. It should be noted that: the transmission motor drives the transmission screw to rotate, so that the threaded sleeve on the surface of the transmission screw drives the support seat 2 to move up and down, so that the drill rod 3 on the support seat 2 drills into the soil. This transmission method is a prior art and will not be described in detail.

[0036] In this embodiment, Figures 1 to 11 As shown, a method for using a mineral geological exploration device and a method for using the same comprises the following steps: S1. When in use, the drilling motor 4 is started to rotate the drill rod 3, and then the support seat 2 drives the drill rod 3 to drill into the soil. When the drill rod 3 is drilled into a suitable position, the machine is stopped, and then the adjusting rod 6 is rotated to rotate synchronously with the main bevel gear ring 904. With the cooperation of the bevel gear rod 903, the slave bevel gear ring 905 is rotated in the opposite direction on the surface of the adjusting rod 6. At this time, the main bevel gear ring 904 and the slave bevel gear ring 905 move synchronously in opposite directions with the corresponding connecting strips 906, so that the two arc-shaped partitions 907 move in opposite directions at the position of the sampling slot 901, so that the sampling slot 901 is released from the sealed state; S2. When the arc-shaped partition 907 is moving, the L-shaped movable rods 913 on the two arc-shaped partitions 907 move synchronously, so that the upper end of the L-shaped movable rod 913 moves along the track of the L-shaped adjustment groove 914 on the top surface of the movable chamber 7, and then the L-shaped movable rod 913 extends from the sampling groove 901 with the scraper 912 and inserts into the inner wall of the borehole. At this time, the scraper 912 moves synchronously with the arc-shaped partition 907 to scrape off the disturbed soil on the inner wall of the borehole; S3. While the arc partition 907 is moving, the guide pin 910 at the top of the arc partition 907 slides along the arc guide groove 909 at the bottom of the isolation plate 908, so that the isolation plate 908 translates between the top of the arc partition 907 and the inner top surface of the sampling groove 901. At this time, the isolation plate 908 is moved out of the sampling groove 901 and inserted into the inner wall of the borehole to prevent the soil at the upper position of the borehole from falling into the sampling groove 901. S4. Finally, the adjusting rod 6 is pressed to move the adjusting rod 6 with the gasket 801 and the movable block 802 downward. At this time, the lower parts of the two movable blocks 802 cooperate with the inclined grooves 807 on both sides of the U-shaped movable plate 806 to slide, so that the U-shaped movable plate 806 extends from the sampling slot 901 with the sampling box 812 through the threaded tube 808. At this time, the open end of the sampling box 812 is inserted into the soil for sampling. After the sampling is completed, the adjusting rod 6 is pulled upward. At this time, the sampling box 812 is reset and moved. As the sampling box 812 is separated from the soil, it is reset with the baffle 810 under the action of the torsion spring 811. At this time, the baffle 810 isolates the sample inside the sampling box 812 and pushes the soil outside the sampling box 812 back into the sampling slot of the borehole, thereby completing the geological survey sampling operation.

When in use, the drilling motor (4) is started to rotate the drill rod (3), and then the support seat (2) drives the drill rod (3) to drill into the soil. When the drill rod (3) is drilled into a suitable position, the machine is stopped, and then the adjusting rod (6) is rotated to rotate synchronously with the main bevel gear ring (904). With the cooperation of the bevel gear rod (903), the slave bevel gear ring (905) is rotated in the opposite direction on the surface of the adjusting rod (6). At this time, the main bevel gear ring (904) and the slave bevel gear ring (905) are synchronously moved in opposite directions with the corresponding connecting strips (906), so that the two arc-shaped partitions (907) move in opposite directions at the position of the sampling slot (901), so that the sampling slot (901) is released from the sealed state; S2. When the arc-shaped partition (907) is moving, the L-shaped movable rods (913) on the two arc-shaped partitions (907) move synchronously, so that the upper ends of the L-shaped movable rods (913) move along the track of the L-shaped adjustment groove (914) on the top surface of the movable chamber (7), and then the L-shaped movable rods (913) with the scraper (912) extend from the sampling groove (901) and insert into the inner wall of the borehole. At this time, the scraper (912) moves synchronously with the arc-shaped partition (907) to scrape off the disturbed soil on the inner wall of the borehole; S3. Simultaneously, during the movement of the arc-shaped partition (907), the guide pin (910) at the top of the arc-shaped partition (907) slides along the track of the arc-shaped guide groove (909) at the bottom of the isolation plate (908), so that the isolation plate (908) moves horizontally between the top of the arc-shaped partition (907) and the inner top surface of the sampling groove (901). At this time, the isolation plate (908) moves out of the sampling groove (901) and is inserted into the inner wall of the borehole, so as to prevent the soil at the upper position of the borehole from falling into the sampling groove (901); S4, finally, the adjusting rod (6) is pressed to move the adjusting rod (6) with the gasket (801) and the movable block (802) downward. At this time, the lower parts of the two movable blocks (802) slide in cooperation with the inclined grooves (807) on both sides of the U-shaped movable plate (806), so that the U-shaped movable plate (806) extends from the sampling slot (901) with the sampling box (812) through the threaded tube (808). At this time, the open end of the sampling box (812) is inserted into the soil for sampling. When the sampling is completed, the adjusting rod (6) is pulled upward, and the sampling box (812) is reset. As the sampling box (812) is separated from the soil, it is reset with the baffle (810) under the action of the torsion spring (811). At this time, the baffle (810) isolates the sample inside the sampling box (812) and pushes the soil outside the sampling box (812) back into the sampling slot of the drill hole, thereby completing the geological survey sampling operation.
