[0013] According to the above technical solution, a liquid storage tank is fixedly sleeved on the outer wall of the sampling tube.

Detailed Implementation

[0021] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of the present application. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without creative effort should fall within the scope of protection of the present application.

[0022] Example 1, as Figures 1-5 As shown, a mineral geological exploration device includes a base 1, a top plate 3, and a sampling cylinder 4. An L-shaped mounting plate 61 is fixedly connected to the upper end of the top plate 3. A motor 62 is fixedly connected to the inner side of the L-shaped mounting plate 61. A transmission rod 63 is fixedly connected to the output end of the motor 62. A spiral conveyor plate 64 is fixedly connected to the bottom of the transmission rod 63 extending into the interior of the sampling cylinder 4. A discharge box 65 is fixedly connected to the bottom of the top plate 3. The sampling cylinder 4 is fixedly connected to the bottom of the discharge box 65. A sample storage box 66 is provided at the bottom of the top plate 3. Multiple sample storage boxes 68 are provided inside the sample storage box 66. An inlet 69 is opened at the upper end of the sample storage box 66 and the bottom of the discharge box 65. A ratchet 610 is fixedly sleeved on the outer wall of the transmission rod 63. A toothed ring 611 is rotatably connected to the upper end of the top plate 3. A pawl 612 is hinged to the inner side of the toothed ring 611 via a pin. A connecting plate 67 is fixedly connected to the top of the sample storage box 66. A toothed plate 613 is fixedly connected to the inner side of the connecting plate 67. The toothed plate 613 meshes with the toothed ring 611.

[0023] The top plate 3 is fixedly connected to the upper end of the slide rail 614, and the connecting plate 67 is slidably connected to the upper end of the slide rail 614. By setting the slide rail 614, the movement of the connecting plate 67 and the sample storage box 66 is precisely guided and limited, ensuring that the sample storage box 66 can slide smoothly in a straight line under the drive of the toothed plate 613, and avoiding the sample storage box 66 from deviating or getting stuck during the movement.

[0024] A spring A615 is fixedly connected to the inner wall of the toothed ring 611. The other end of the spring A615 is fixedly connected to the pawl 612. By setting the spring A615, the pawl 612 always tends to engage with the tooth groove of the ratchet 610, ensuring that the ratchet 610 can reliably drive the pawl 612 and the toothed ring 611 to rotate when the motor 62 reverses, thereby realizing the automatic box changing action of the sample box 66.

[0025] A hydraulic telescopic rod 2 is fixedly connected to the upper end of the base 1. The output end of the hydraulic telescopic rod 2 is fixedly connected to the bottom of the top plate 3. A crushing disc 5 is assembled at the bottom of the sampling cylinder 4. In this embodiment, when the motor 62 rotates counterclockwise for sampling, the ratchet 610 rotates without driving the toothed ring 611 and the sample storage box 66 remains stationary to ensure continuous and stable sampling. When the motor 62 rotates clockwise, the ratchet 610 drives the toothed ring 611 to rotate through the pawl 612, and then drives the sample storage box 66 to slide along the slide rail 614 through the toothed plate 613 to achieve automatic box changing. This achieves the effect of automatically aligning the next empty sample storage box 68 with the feed port 69 after sampling, effectively avoiding the risk of sample confusion caused by manual box changing.

[0026] When the above equipment is used, when sampling is required, the hydraulic telescopic rod 2 is activated first, which causes the top plate 3 to move downward. Then the top plate 3 will move the sampling cylinder 4 at its lower end downward. The crushing disc 5 at the bottom of the sampling cylinder 4 will first contact the ground, and then the crushing disc 5 will start to rotate to crush and push away the gravel and other debris on the ground. At this time, the baffle 72 inside the sampling cylinder 4 is in the closed state. When the specified depth is reached, the baffle 72 will open with the cooperation. At this time, the motor 62 is started. After the motor 62 starts, it first drives the transmission rod 63 to rotate. The spiral conveyor plate 64 on the transmission rod 63 rotates accordingly, continuously conveying the ore and soil samples crushed by the crushing disc 5 upward. The soil sample smoothly enters the interior of the discharge box 65 and falls vertically into the storage box 68 currently aligned inside the storage box 66 through the inlet 69. During the sampling stage, the ratchet 610 on the transmission rod 63 rotates counterclockwise synchronously with the rod. At this time, the ratchet 610 will not drive the pawl 612 to move, so the toothed ring 611 remains stationary. When a single sampling operation is completed, the motor 62 reverses, and the transmission rod 63 drives the spiral conveyor 64 to rotate in the opposite direction. The spiral blades will scrape off the small amount of residual soil sample remaining on the surface to ensure that the channel is clean. At the same time, the rotating ratchet 610 will drive the toothed ring 611 to rotate through the pawl 612. Since the toothed ring 611 meshes with the toothed plate 613 on the inner side of the connecting plate 67, the toothed plate 613 will move accordingly, thus driving the connecting plate 67 to slide on the outer wall of the slide rail 614. The connecting plate 67 will drive the sample storage box 66 to move. When the reverse rotation stroke ends, the full box that was originally connected to the feed port 69 will be removed, and the next empty sample storage box 68 inside the sample storage box 66 will move to the bottom of the feed port 69, completing one automatic box change.

[0027] Example 2, as Figures 4-8 As shown, based on Embodiment 1, a protective sleeve 71 is fixedly connected to the outer wall of the sampling cylinder 4, a baffle 72 is slidably passed through the cylinder body of the sampling cylinder 4, an movable opening 73 is provided on the inner side of the baffle 72, a moving rod 74 is slidably passed through the upper end of the protective sleeve 71, a circular ring plate 76 and a trapezoidal block 75 are fixedly connected to the upper and lower ends of the moving rod 74 respectively, a linkage rod 77 is fixedly connected to the outer wall of the circular ring plate 76, a spring B78 is fixedly connected between the inner wall of the protective sleeve 71 and the outer side of the baffle 72, and a spring C79 is fixedly connected between the trapezoidal block 75 and the inner wall of the protective sleeve 71.

[0028] The inclined surface of the trapezoidal block 75 is in contact with the lower side wall of the movable port 73 away from the sampling cylinder 4, and the wall of the movable port 73 is set to be arc-shaped. By setting the lower side wall of the movable port 73 to be arc-shaped and in contact with the inclined surface of the trapezoidal block 75, the inclined surface of the trapezoidal block 75 can smoothly push the baffle 72 to slide outward to open the bottom opening of the sampling cylinder 4 when the trapezoidal block 75 rises. The arc-shaped mating surface reduces the sliding friction resistance and avoids jamming between the trapezoidal block 75 and the movable port 73.

[0029] An adjustable trigger is mounted on the upper end of the base 1. The adjustable trigger includes a fixed cylinder 710, a sliding rod 711, a positioning hole 712, and a positioning bolt 713. The fixed cylinder 710 is fixedly connected to the upper end of the base 1, and the sliding rod 711 is slidably connected to the inner wall of the fixed cylinder 710. The positioning hole 712 is opened inside the fixed cylinder 710 and the sliding rod 711, and the positioning bolt 713 is inserted into the positioning hole 712 that coincides inside the fixed cylinder 710 and the sliding rod 711. In this embodiment, by adjusting the sliding rod 711 to different heights, the contact time between the linkage rod 77 and the top of the sliding rod 711 is changed, achieving the effect of adjustable sampling depth and automatic sampling at the preset depth. This effectively prevents surface soil from entering the sampling cylinder 4 prematurely and contaminating the deep samples during drilling, and improves the adaptability of sampling at different depths.

[0030] When the above-mentioned device is used, firstly, according to the required sampling depth, slide the slide rod 711 to a suitable position inside the fixed cylinder 710, and then insert the positioning bolt 713 into the positioning hole 712 that coincides at this time. In this way, the overall height of the slide rod 711 and the fixed cylinder 710 can be adjusted, thereby changing the contact time between the top of the linkage rod 77 and the slide rod 711. Next, the hydraulic telescopic rod 2 is activated. The hydraulic telescopic rod 2 drives the top plate 3 and the sampling cylinder 4 to move downward. At this time, the baffle 72 inside the sampling cylinder 4 is in a tightly closed state under the pushing force of the spring B78, sealing the bottom opening of the sampling cylinder 4 and preventing the surface soil from falling into the cylinder in advance during the drilling process and contaminating the deep sample. As the hydraulic telescopic rod 2 pushes the sampling cylinder 4 downward, when it reaches the preset sampling depth, the bottom of the linkage rod 77 just touches and presses against the top of the slide rod 711. At this time, the hydraulic telescopic rod 2 continues to provide downward thrust, and the linkage rod 77 will move upward relative to the sampling cylinder 4. The rise of the linkage rod 77 drives the connected annular plate 76 to move upward, thereby pushing the moving rod 74 to slide upward along the protective sleeve 71. The trapezoidal block 75 at the upper end of the moving rod 74 is raised synchronously. Since the inclined surface of the trapezoidal block 75 is in close contact with the lower side wall of the movable opening 73 inside the baffle 72, as the trapezoidal block 75 slides upward, its inclined surface generates an outward pushing force on the movable opening 73, pushing the baffle 72 away from the outside of the sampling tube 4, so that the soil sample of the stratum after being broken by the crushing disc 5 can smoothly enter the interior of the sampling tube 4.

[0031] Example 3, as Figures 7-9 As shown, based on Embodiment 1 (or Embodiment 2), a liquid storage tank 81 is fixedly fitted on the outer wall of the sampling cylinder 4. An annular tube 82 is assembled inside the cylinder of the sampling cylinder 4. The annular tube 82 is connected to the liquid storage tank 81 through a connecting pipe. A water supply pipe 86 is assembled at the bottom of the annular tube 82. A nozzle 87 is assembled on the outer wall of the water supply pipe 86. Multiple annular grooves 83 are opened inside the cylinder of the sampling cylinder 4. An annular plate 84 is rotatably connected inside the annular groove 83. An opening 85 is opened between the annular plate 84 and the inner wall of the sampling cylinder 4. A connecting block 88 is fixedly connected to the outer wall of the annular plate 84. A movable block 89 is fixedly connected to the other end of the connecting block 88. An inclined groove 810 is opened on the outer wall of the movable block 89. An installation block 811 is fixedly connected to the outer wall of the moving rod 74. A sliding shaft 812 is fixedly connected to the inner side of the installation block 811. The sliding shaft 812 is slidably connected inside the inclined groove 810.

[0032] The outer wall of the sampling cylinder 4 is provided with a receiving port 813. The connecting block 88 moves through the sampling cylinder 4 through the receiving port 813. By setting the receiving port 813, the connecting block 88 is provided with space for horizontal movement and stroke limit, so that the horizontal sliding of the movable block 89 can be transmitted to the annular plate 84 through the connecting block 88, driving the annular plate 84 to rotate inside the annular groove 83.

[0033] A protective box 814 is fixedly connected to the outer wall of the sampling tube 4. The movable block 89, the mounting block 811, and the sliding shaft 812 are located inside the protective box 814.

[0034] In this embodiment, the annular plate 84 is driven to rotate within the annular groove 83, causing the opening 85 to be closed off from the liquid channel in the sampling cylinder 4, thus preventing soil particles from entering the annular groove 83. After sampling, the moving rod 74 is reset, causing the annular plate 84 to reverse and open the opening 85. The liquid in the storage tank 81 is sprayed out from the nozzle 87 through the annular pipe 82, achieving automatic opening of the opening 85 during sampling and water spraying to clean the cylinder wall after sampling.

[0035] When the above equipment is used, when the hydraulic telescopic rod 2 pushes the sampling cylinder 4 down until the linkage rod 77 touches and presses on the top of the slide rod 711, the moving rod 74 begins to slide upward in the protective sleeve 71. As the moving rod 74 rises, the mounting block 811 on its outer wall drives the sliding shaft 812 to move vertically upward in sync. Since the sliding shaft 812 is always slidably engaged inside the inclined groove 810, when the sliding shaft 812 moves upward along the inclined surface of the inclined groove 810, the inclination angle of the inclined groove 810 forces the movable block 89 to overcome the resistance and slide horizontally inward. The displacement of the movable block 89 drives the annular plate 84 to rotate at a certain angle inside the annular groove 83 through the connecting block 88 passing through the receiving port 813. When the moving rod 74 slides upward to the highest point, the annular plate 84 also rotates to the specified angle. At this time, the opening 85 on the annular plate 84 is completely offset from the liquid channel inside the sampling cylinder 4, thus preventing flying soil particles from entering the interior of the annular groove 83. When sampling is completed, the hydraulic telescopic rod 2 retracts, causing the sampling cylinder 4 to move upward. The linkage rod 77 disengages from the slide rod 711, and the moving rod 74 resets downward under the action of the spring. The sliding shaft 812 descends along the inclined groove 810, causing the movable block 89 to rotate and the annular plate 84 to reverse, so that the opening 85 overlaps and connects again. The water in the storage tank 81 flows into the annular pipe 82 through the connecting pipe, and then flows downward through the water supply pipe 86, and is sprayed out evenly in an umbrella shape from the nozzle 87. This thoroughly flushes and cleans the inner wall of the sampling cylinder 4, the surface of the baffle 72, and the crushing disc 5 below, effectively removing the loose soil and debris that adhered to the cylinder wall during the drilling process.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
