[0025] The present application is further described in detail below in conjunction with all the accompanying drawings. Example

[0026] The embodiment of the present application discloses a mineral geological exploration sampling device.

[0028] Reference Figure 2 and Figure 3 The base 1 has a middle hole 13 in the middle, and a sampling barrel 2 is arranged on the base 1 above the middle hole 13. A support bracket 3 is installed on the base 1, and a driving assembly 4 is installed on the support bracket 3 for rotating the sampling barrel 2 during the downward movement. The driving assembly 4 includes a connecting sprocket 41, a driving sprocket 42, a first connecting chain 43, a double-axis motor 45, and a motor bracket 46. The motor bracket 46 is located in the supporting bracket 3, and the double-axis motor 45 is installed in the motor bracket 46. The driving sprocket 42 is coaxially fixedly connected with one of the output shafts of the double-axis motor 45. The connecting sprocket 41 is sleeved on the outer wall of the sampling barrel 2, and the connecting sprocket 41 and the driving sprocket 42 are connected by the first connecting chain 43. When the double-axis motor 45 is started, the output shaft of the double-axis motor 45 rotates, the driving sprocket 42 rotates, and the connecting sprocket 41 is driven to rotate through the first connecting chain 43, so that the sampling barrel 2 rotates.

[0029] A first bevel gear 47 is coaxially fixedly connected to the other output shaft of the dual-axis motor 45 away from the driving sprocket 42, a second bevel gear 48 is rotatably connected to the motor bracket 46, the first bevel gear 47 and the second bevel gear 48 are meshed, a connecting shaft 491 is coaxially fixedly connected to the second bevel gear 48, a lifting gear 49 is coaxially fixedly connected to the end of the connecting shaft 491 away from the second bevel gear 48, a lifting rack 31 is vertically arranged on the support bracket 3, and the lifting gear 49 is meshed with the lifting rack 31. Start the dual-axis motor 45, the output shaft of the dual-axis motor 45 rotates, and the lifting gear 49 is driven to rotate through the meshing first bevel gear 47 and second bevel gear 48, and the lifting gear 49 moves up and down through the lifting rack 31, thereby driving the motor bracket 46 and the sampling tube 2 to move up and down, so that the sampling tube 2 moves downward during the rotation process for drilling.

[0030] Reference Figure 2 A protective frame 462 is fixedly installed on the motor bracket 46, the first connecting chain 43 and the connecting sprocket 41 are both located in the protective frame 462, the connecting sprocket 41 is located in the protective frame 462, and the upper and lower ends of the protective frame 462 are provided with passages for the sampling tube 2 to pass through, and the protective frame 462 protects the connecting sprocket 41 and the first connecting chain 43.

[0031] Reference Figure 2, the limiting blocks 461 are fixedly installed on both sides of the motor bracket 46, and the support bracket 3 is provided with a limiting groove 32 in the vertical direction to match the limiting blocks 461. The limiting blocks 461 are located in the limiting groove 32 and are slidably connected to the support bracket 3. During the movement of the motor bracket 46, the limiting blocks 461 move along the limiting groove 32 to improve the stability of the movement of the motor bracket 46.

[0032] Reference Figure 2 A sampling drill rod 5 is installed in the sampling barrel 2, a sampling groove 51 is provided on the side wall of the sampling drill rod 5, and a cutting blade 21 is provided at the bottom of the sampling barrel 2. The base 1 is moved to the sampling position, and the sampling barrel 2 is driven downward by the driving assembly 4, and the cutting blade 21 on the sampling barrel 2 cuts the soil, and at the same time, the sampling drill rod 5 in the sampling barrel 2 drills the soil. Since the cutting blade 21 squeezes the soil toward the sampling barrel 2 during the rotation of the sampling barrel 2, the soil cut by the cutting blade 21 on the sampling barrel 2 moves toward the sampling drill rod 5, filling the sampling groove 51 on the sampling drill rod 5, so as to facilitate the sampling of the soil.

[0033] Reference Figure 2 A thread groove 22 is provided at the top of the sampling barrel 2, a threaded rod 52 matching the thread groove 22 is provided at the top of the sampling drill rod 5, a connecting rod 6 is passed through the top of the threaded rod 52, one end of the connecting rod 6 is located outside the sampling barrel 2 and a rotating block 61 is provided at the end of the connecting rod 6, the connecting rod 6 is divided into a connecting portion 62 and a rotating portion 63, the rotating portion 63 is rotatably connected to the sampling barrel 2, the cross section of the connecting portion 62 is a polygon, and the connecting portion 62 is slidably connected to the threaded rod 52. By rotating the rotating block 61 at the top of the connecting rod 6, the rotating portion 63 rotates in the sampling barrel 2, and the connecting portion 62 drives the threaded rod 52 to rotate, thereby adjusting the position of the sampling drill bit in the sampling barrel 2.

[0034] Among them, the rotation direction in the present application document is observed from top to bottom, and the direction of the internal thread groove 22 of the sampling barrel 2 is clockwise. When the output shaft of the dual-axis motor 45 rotates counterclockwise, the sampling barrel 2 rotates counterclockwise during the downward movement. Since the internal thread groove 22 of the sampling barrel 2 rotates counterclockwise, when the sampling drill bit encounters soil resistance, the sampling barrel 2 will move the sampling drill bit downward through the thread groove 22 during the rotation process, thereby better performing soil sampling; when the sampling barrel 2 moves upward, the output shaft of the dual-axis motor 45 rotates clockwise. When the sampling drill bit encounters soil resistance, the sampling drill bit will move upward through the thread groove 22, thereby better removing the sampling drill bit from the soil and improving the sampling effect.

[0035] Reference Figure 1 and Figure 2The base 1 is rotatably connected with a plurality of rotating sprockets 71, and a plurality of rotating sprockets 71 are vertically penetrated with positioning screws 7, and the plurality of positioning screws 7 are circumferentially arranged with the middle hole 13 as the center. The plurality of positioning screws 7 pass through the base 1 and extend to the bottom of the base 1, and a positioning block 72 is arranged on the lower end surface of the plurality of positioning screws 7. When the sampling position is determined, the rotating sprocket 71 is rotated to move the positioning screw 7 downward, and the positioning block 72 abuts against the ground to locate the sampling position, and the sampling tube 2 passes through the middle hole 13 to work, thereby improving the accuracy.

[0036] Reference Figure 1 and Figure 2 The base 1 is provided with a driving sprocket 74, and the base 1 is provided with a driving motor 73 for rotating the driving sprocket 74. The driving sprocket 74 is connected to all the rotating sprockets 71 through a second connecting chain 75, and the top ends of adjacent positioning screws 7 are connected through a limiting rod 76. The driving motor 73 is started to rotate the driving sprocket 74, and all the rotating sprockets 71 are driven to rotate synchronously through the second connecting chain 75. The limiting rod 76 limits the positioning screw 7. When the rotating sprocket 71 rotates, the positioning screw 7 can only move vertically up and down under the influence of the limiting rod 76.

[0037] The implementation principle of a mineral geological exploration sampling device in an embodiment of the present application is as follows: the base 1 is moved to the sampling position, the double-axis motor 45 is started, and the output shaft of the double-axis motor 45 rotates. The output shaft at one end of the double-axis motor 45 rotates to drive the driving sprocket 42 to rotate, and drives the connecting sprocket 41 to rotate through the first connecting chain 43, so that the sampling barrel 2 rotates, and the output shaft at the other end of the double-axis motor 45 rotates, and drives the lifting gear 49 to rotate through the meshing first bevel gear 47 and second bevel gear 48. The lifting gear 49 moves up and down through the lifting rack 31, thereby driving the motor bracket 46 and the sampling barrel 2 to move up and down, so that the sampling barrel 2 moves downward during the rotation process for drilling, and the cutting blade 21 on the sampling barrel 2 cuts the soil, and at the same time, the sampling drill rod 5 in the sampling barrel 2 drills into the soil. Due to the centripetal force of the rotation of the sampling barrel 2, the soil cut by the cutting blade 21 on the sampling barrel 2 moves toward the sampling drill rod 5, filling the sampling groove 51 on the sampling drill rod 5, which is convenient for sampling the soil.

Due to the centripetal force of the rotation of the sampling tube 2, the soil cut by the cutting blade 21 on the sampling tube 2 moves toward the sampling drill rod 5 and fills the sampling groove 51 on the sampling drill rod 5. After the sampling is completed, the sampling tube 2 and the sampling drill rod 5 are moved upward to take out the soil in the sampling groove 51 .
