Description

Technical Field

[0001] The utility model relates to the field of mine ecological governance. Specifically, it relates to a mine ecological governance exploration and construction device. Background Art

[0002] With the exploitation of mines, the ecological environment of mines has been severely damaged by humans. The main ecological problems caused are geological disasters, destruction of landforms, destruction of land resources, pollution of soil and water resources, etc. The restoration and governance of mines include the governance of the mining area environment, the restoration of land functions, and the protection of the mining area ecological environment. Before formulating a mine ecological governance plan, it is necessary to first explore the geological environment of the mining area to understand the situation of the mine to be restored.

[0003] The existing mine exploration methods mainly involve inserting tools such as sampling pipes or Luoyang shovels into the soil to extract the soil and then analyzing it. However, in mines, coal powder, gangue, and soil are mixed and relatively loose. When the sampling tool is pulled out upwards, the sampled soil easily falls back, which greatly affects the sampling efficiency.

[0004] A patent with the application number 202223275053.3 discloses a mine ecological governance exploration and construction device. By setting a screw blade inside the sampling pipe, when the sampling pipe is inserted into the soil, the screw blade is driven to rotate by a servo motor to compact the sampled soil, thereby preventing the sampled soil from falling out when the sampling pipe is extracted. However, its structure is relatively complex, the operation is also rather cumbersome, and it is not very convenient to use.

[0005] In order to solve the above problems, people have been seeking an ideal technical solution. Summary of the Invention

[0006] The purpose of the utility model is to address the deficiencies of the prior art, and thus provide a mine ecological governance exploration and construction device with scientific design, simple structure, convenient operation, and strong practicability.

[0007] To achieve the above purpose, the technical solution adopted by the utility model is: a mine ecological governance exploration and construction device, including a sampling outer pipe and a sampling inner pipe. The sampling outer pipe is rotatably sleeved outside the sampling inner pipe. The bottom end of the sampling outer pipe extends beyond the bottom end of the sampling inner pipe. A first radial stop bar is spanned on the bottom end surface of the sampling outer pipe, and a second radial stop bar is spanned on the inner wall of the bottom end of the sampling inner pipe. Through the relative rotation of the sampling outer pipe and the sampling inner pipe, the first radial stop bar and the second radial stop bar can overlap or stagger.

[0008] Based on the above, a third radial stop rod is also hinged to the center of the top of the first radial stop rod. Both ends of the third radial stop rod extend to the inner wall of the bottom end of the sampling outer tube. An angular limit block is arranged on the bottom end surface of the sampling inner tube. The angular limit block restricts the third radial stop rod to rotate within the range from overlapping with the second radial stop rod to an included angle of 60°. A horizontal strip-shaped groove is formed on the bottom surface of the third radial stop rod, and a horizontal strip-shaped protrusion is arranged on the top surface of the first radial stop rod corresponding to the horizontal strip-shaped groove. Through the elastic deformation of the first radial stop rod and the third radial stop rod, the horizontal strip-shaped protrusion can be clamped into the horizontal strip-shaped groove or disengaged from the horizontal strip-shaped groove.

[0009] Based on the above, the top of the sampling inner tube extends out from the top of the sampling outer tube. Three first handles are arranged at equal intervals on the outer wall of the top of the sampling inner tube, and three second handles are arranged at equal intervals on the outer wall of the top of the sampling outer tube; when the first radial stop rod, the second radial stop rod, and the third radial stop rod overlap, the first handle and the second handle also overlap.

[0010] Based on the above, the first radial stop rod has a structure that is narrow at the bottom and wide at the top, and the widths of the second radial stop rod and the third radial stop rod are both equal to the width of the top surface of the first radial stop rod.

[0011] The utility model has substantial features and progress compared with the prior art. Specifically, the utility model has the following advantages:

[0012] (1) Through the relative rotation of the sampling outer tube and the sampling inner tube, the first radial stop rod, the second radial stop rod, and the third radial stop rod can first overlap together, and the pipe orifice is equally divided from the middle, which can reduce the resistance when inserting into the mine soil; after reaching the bottom, the sample soil enters the sampling inner tube, and then the sampling outer tube is rotated alone. The first radial stop rod first drives the third radial stop rod to rotate together. After being blocked by the angular limit block, the horizontal strip-shaped protrusion disengages from the horizontal strip-shaped groove. The first radial stop rod continues to rotate until the included angles between the three are all 60°, and the pipe orifice is equally divided into six parts, thereby increasing the resistance for the sample soil to fall from the tube and enabling it to be smoothly pulled out of the soil.

[0013] (2) The setting of the angular limit block can limit the rotation angle of the third radial stop rod. Through the cooperation of the horizontal strip-shaped groove and the horizontal strip-shaped protrusion, the first radial stop rod can drive the third radial stop rod to rotate together. When the third radial stop rod is blocked by the angular limit block, through deformation, the horizontal strip-shaped protrusion disengages from the horizontal strip-shaped groove, enabling the two to be staggered from each other.

[0014] (3) By providing three of the first handles and three of the second handles, it is convenient for workers to observe the overlapping and staggered conditions of the radial bars on the ground, thereby facilitating operation.

[0015] (4) The first radial barrier rod is narrow at the bottom and wide at the top, which can further reduce the downward resistance in the soil. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0020] The technical solution of the utility model is further described in detail below through specific implementation methods.

[0021] like Figures 1-3 As shown, a mine ecological management exploration and construction device includes a sampling outer tube 1 and a sampling inner tube 2. The sampling outer tube 1 is rotatably sleeved on the outside of the sampling inner tube 2, the bottom end of the sampling outer tube 1 is arranged beyond the bottom end of the sampling inner tube 2, and the top of the sampling inner tube 2 is extended from the top of the sampling outer tube 1.

[0022] A first radial baffle 3 is spanned on the bottom end surface of the sampling outer tube 1, a second radial baffle 4 is spanned on the inner wall of the bottom end of the sampling inner tube 2, a third radial baffle 5 is hinged at the top center of the first radial baffle 3, both ends of the third radial baffle 5 extend to the inner wall of the bottom end of the sampling outer tube 1, and an angle limit block 6 is provided on the bottom end surface of the sampling inner tube 2, and the angle limit block 6 limits the third radial baffle 5 from rotating within the range of overlapping with the second radial baffle 4 to an angle of 60°.

[0023] A horizontal strip-shaped groove 7 is formed on the bottom surface of the third radial stop lever 5, and a horizontal strip-shaped protrusion 8 is provided on the top surface of the first radial stop lever 3 corresponding to the horizontal strip-shaped groove 7. Through the elastic deformation of the first radial stop lever 3 and the third radial stop lever 5, the horizontal strip-shaped protrusion 8 can be engaged with or disengaged from the horizontal strip-shaped groove 7. In this way, through the relative rotation of the sampling outer tube 1 and the sampling inner tube 2, the first radial stop lever 3, the second radial stop lever 4, and the third radial stop lever 5 can overlap or stagger.

[0024] Working principle:

[0025] First, through the relative rotation of the sampling outer tube 1 and the sampling inner tube 2, the first radial stop lever 3, the second radial stop lever 4, and the third radial stop lever 5 are overlapped. At this time, the horizontal strip-shaped protrusion 8 is engaged with the horizontal strip-shaped groove 7, and the pipe orifice is equally divided from the middle, which can reduce the resistance when inserted into the mine soil, and start to probe down for sampling; after reaching the sampling depth, the soil sample enters the sampling inner tube 2. Then, the sampling outer tube 1 is rotated alone. The first radial stop lever 3 first drives the third radial stop lever 5 to rotate together. After being blocked by the angle limit block 6, through deformation, the horizontal strip-shaped protrusion 8 is disengaged from the horizontal strip-shaped groove 7; the first radial stop lever 3 continues to rotate until the included angle between the three is 60°, and the pipe orifice is equally divided into six parts, increasing the resistance of the soil sample falling from the tube, so that it can be smoothly pulled out of the soil.

[0026] For the convenience of observation and operation on the ground, three first handles 9 are equally spaced on the outer wall of the top of the sampling inner tube 2, and three second handles 10 are equally spaced on the outer wall of the top of the sampling outer tube 1; when the first radial stop lever 3, the second radial stop lever 4, and the third radial stop lever 5 overlap, the first handle 9 and the second handle 10 also overlap; in this way, the staff on the ground can observe the overlap and stagger of each radial stop lever.

[0027] In order to further reduce the resistance of entering the soil, the first radial stop lever 3 has a structure that is narrow at the bottom and wide at the top, and the widths of the second radial stop lever 4 and the third radial stop lever 5 are equal to the width of the top surface of the first radial stop lever 3.

[0028] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still can modify the specific implementation manners of the present invention or perform equivalent replacements for some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
