Description

Technical Field

[0001] The utility model relates to the field of geological exploration, in particular to a soil layer sampling device for mine geological exploration. Background Art

[0002] Mining geological exploration is a comprehensive and systematic process, which aims to conduct detailed exploration and evaluation of geological conditions and mineral resources in the mining area through a series of methods and technologies. The main purpose of mining geological exploration is to provide a basis for mine design and construction, including the identification of mineral reserves, ore quality, mining, selection and smelting processing conditions and technical and economic evaluation of ore deposits. Its tasks cover the entire process from preliminary preparation to exploration results evaluation, ensuring the scientific and economic development of mines.

[0003] At present, in the process of mine geological exploration, soil stratification sampling devices for mine geological exploration are often used to sample the soil to be tested, and to perform necessary sampling, testing and analysis on the soil.

[0004] Existing sampling devices usually use motors to drive sampling rings to go deep underground to sample the soil at a set depth. Existing equipment usually collects soil directly with sampling rings, and the soil is stored in the sampling rings. The sampling rings usually open directly downward, so that the soil samples obtained are mixed with each other, and the soil conditions at the specified depth cannot be observed. The soil analysis is not accurate enough, which affects subsequent work. On the other hand, when sampling soil, existing devices usually hold the sampling device directly by hand without a stabilizing device, which makes it impossible for the sampling device to run vertically downward. Not only does it make the sampling device more difficult to hold when the motor is rotating, but the angle deviation makes it impossible for the sampling device to estimate the depth of exploration, resulting in deviations in the composition of the sampled soil, which has an adverse effect on subsequent soil analysis and soil pollution control.

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.

[0031] Referring to Figure 1 - Figure 2 , an embodiment provided by the present utility model: a soil layer sampling device for mine geological exploration, including a handheld machine chamber 1 convenient for handheld operation. Handheld grips are provided on the left and right of the handheld machine chamber 1. A rotating motor 2 is fixedly connected inside the handheld machine chamber 1. A motor bracket 3 is fixedly connected to the bottom of the handheld machine chamber 1. The bottom end output shaft of the rotating motor 2 is fixedly connected to a rotating shaft 4. When the rotating motor 2 is turned on, the bottom end output shaft of the rotating motor 2 will drive the rotating shaft 4 to rotate. The inside of the motor bracket 3 is rotatably connected to the outer periphery of the rotating shaft 4. A rotating sleeve 5 is rotatably connected to the outer periphery of the rotating shaft 4. The top end of the rotating sleeve 5 is fixedly connected to a rotating handle 6. By turning the rotating handle 6, the rotating sleeve 5 can be driven to rotate. The inside of the rotating handle 6 is rotatably connected to the outer periphery of the rotating shaft 4. A fixed sleeve 7 for fixing and supporting is rotatably connected to the outer periphery of the rotating sleeve 5. A limiting component is fixedly connected to the outer periphery of the fixed sleeve 7.

[0032] Referring to Figure 2 - Figure 3, a rotating disk 8 is fixedly connected to the bottom end of the fixed sleeve 7. A soil collection cylinder 9 for collecting soil is rotatably connected to the outer periphery of the rotating disk 8. A sliding groove 10 is formed at the bottom of the rotating disk 8. There are four groups of sliding grooves 10, which are annularly and evenly distributed inside the rotating disk 8. A collection port 11 for facilitating the entry of soil is formed at the top of the sliding groove 10. There are four groups of collection ports 11, which are communicated with the sliding groove 10. A connecting rod 12 is hinged to the bottom of the rotating sleeve 5. A shielding component is hinged to the top of the connecting rod 12. The shielding component includes a baffle 13. The bottom of the baffle 13 is hinged to the top of the connecting rod 12. When the rotating sleeve 5 rotates, it will drive the baffle 13 to move inward through the connecting rod 12. A limiting block 14 is fixedly connected to the outer side of the baffle 13. There are two groups of limiting blocks 14, which are symmetrically arranged on the outer side of the baffle 13. The outer periphery of the baffle 13 is slidably connected inside the sliding groove 10. The sliding groove 10 restricts the baffle 13 to slide only along the inner wall of the sliding groove 10. A limiting groove 15 is formed on the outer side of the sliding groove 10. There are two groups of limiting grooves 15, which are symmetrically arranged on the inner walls of both sides of the sliding groove 10. The inner side of the limiting block 14 is elastically connected to the inner side of the limiting groove 15 through a limiting spring 16. When the limiting block 14 is not stressed, the limiting spring 16 will push the limiting block 14 to move outward. At this time, the limiting block 14 will drive the baffle 13 to block the collection port 11. The outer periphery of the limiting block 14 is slidably connected inside the limiting groove 15. A drill bit 17 is fixedly connected to the bottom of the rotating shaft 4. The rotating shaft 4 drives the drill bit 17 to rotate, thereby breaking the soil. The top of the drill bit 17 is rotatably connected to the bottom of the soil collection cylinder 9.

[0033] Referring to Figure 1 and Figure 3 , the limiting component includes a fixed bracket 18 that plays a role in fixed support. The fixed bracket 18 is triangular, and the three corners are fixed by circular rings. The inner part of the front circular ring of the fixed bracket 18 is fixedly connected to the outer periphery of the fixed sleeve 7. A group of sliding columns 19 are respectively slidably connected inside the two rear circular rings of the fixed bracket 18. The two groups of sliding columns 19 will restrict the fixed bracket 18 to slide up and down only along the inner wall of the sliding column 19. The bottom of the sliding column 19 is fixedly connected to a bottom plate 21. The sliding column 19 and the bottom plate 21 are perpendicularly distributed. The bottom end of the fixed bracket 18 is elastically connected to the top of the bottom plate 21 through a return spring 20. When the fixed bracket 18 is not stressed, the return spring 20 will push the fixed bracket 18 to move upward. A through hole 22 is formed inside the bottom plate 21. The position of the through hole 22 is opposite to the position of the drill bit 17. One end of the return spring 20 is fixedly connected to the bottom of the fixed bracket 18, and the other end of the return spring 20 is fixedly connected to the top end of the bottom plate 21, so that the fixed bracket 18 is kept at the top end of the sliding column 19.

[0034] Working principle: When it is necessary to sample the soil at a specified depth, turn on the rotation motor 2. The output shaft at the bottom of the rotation motor 2 will drive the drill bit 17 to rotate. At this time, hold the handheld machine housing 1 and push the handheld machine housing 1 downward to make the drill bit 17 break through the soil and move downward. When the drill bit 17 reaches the specified depth, turn the rotation handle 6. The rotation handle 6 drives the rotation sleeve 5 to rotate. The rotation sleeve 5 drives the baffle 13 to move towards the center of the rotation disc 8 through the connecting rod 12, and at the same time compresses the limit spring 16. At this time, the baffle 13 no longer blocks the collection port 11. Lift the handheld machine housing 1 upward, then the soil will enter the inside of the collection cylinder 9. At this time, turn the rotation handle 6 again to reset the baffle 13 to block the collection port 11, then the soil at the specified depth can be collected. When it is necessary to keep the sampling device moving relatively stably and vertically when holding it by hand, hold the handheld machine housing 1 with the hand and push the handheld machine housing 1 downward. The handheld machine housing 1 drives the rotation motor 2 downward, the rotation motor 2 drives the rotation shaft 4 downward, the rotation shaft 4 drives the rotation sleeve 5 and the fixed sleeve 7 downward, the fixed sleeve 7 drives the fixed bracket 18 downward, and the fixed bracket 18 moves downward along the outer walls of the left and right groups of sliding columns 19 and compresses the return spring 20. The two groups of sliding columns 19 keep the fixed bracket 18 stable during the downward movement, and at the same time the sliding columns 19 are perpendicular to the bottom plate 21, so that the drill bit 17 is perpendicular to the ground.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
