[0001] The invention belongs to the technical field of mine geological exploration, in particular to a soil taking device for mine geological exploration. Background Art

[0002] A mine is a passage used to mine underground mineral resources. A mine is usually composed of a series of tunnels, inclined shafts, vertical shafts and horizontal tunnels, forming a complex underground network that allows the entry and exit of workers, equipment, and materials, as well as the extraction of ore and the discharge of waste rock.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 12 As shown, the present invention provides a soil-taking device for mine geological survey, comprising a base 2 and a plurality of positioning rods 3 arranged at equal angles at the bottom of the base 2 in an annular direction, a motor 1 is fixedly mounted on the top of the base 2, and further comprising:

[0039] A derivation assembly 4 fixedly mounted on the bottom of the base 2;

[0040] A sampling assembly 6 and two groups of power transmission assemblies 7 are arranged at the bottom of the derivation assembly 4, and each two power transmission assemblies 7 form a group;

[0041] A docking assembly 5 is arranged on the periphery of the sampling assembly 6, and two derivation assemblies 4, sampling assemblies 6 and each group of power transmission assemblies 7 are respectively provided and are distributed up and down;

[0042] The upper end derivation assembly 4 includes a limit housing 41 fixed to the bottom of the base 2;

[0043] The upper sampling assembly 6 includes a sampling barrel 61 movably mounted on the bottom of the limiting shell 41. The outer periphery of the sampling barrel 61 is hinged with two sampling plates 63 through two extension plates 62. The interior of the sampling barrel 61 is movably connected with two tooth plates 1 64. The tops of the two tooth plates 1 64 are equidistantly provided with a plurality of guide rods 2 65. The interior of the sampling barrel 61 is movably mounted with a tooth plate 2 66 through two groups of hydraulic rods 67. The tooth plate 2 66 is elastically connected to the sampling barrel 61 through a spring telescopic rod 2 69. Each tooth plate 1 64 is elastically connected to the sampling barrel 61 through a tension spring 68.

[0044] The motor 1 pulls the tooth plate 64 to extend outward through the derivation assembly 4;

[0045] Every two limiting shells 41 are connected via a docking assembly 5 .

[0046] The outer circumference of the sampling tube 61 is provided with two slots for the entry of ore, the sampling plate 63 is located on the side of the slot, the tooth plate 1 64 is ball-axled connected to the sampling plate 63, each set of hydraulic rods 67 has two and are symmetrically distributed on the side of the tooth plate 2 66, the teeth of the tooth plate 2 66 and the tooth plate 1 64 are inclined and mesh with each other.

[0047] Adopting the above scheme: when the device needs to perform sampling work, it is preferred to use drilling equipment to drill holes in the ground. It should be noted that several positioning rods 3 form a circle, and the inner diameter of the hole should be smaller than the diameter of the circle formed by the positioning rods 3, and larger than the outer diameter of the docking component 5. When the depth position specified by the hole is reached, the device can be placed in the hole, and the positioning rod 3 is inserted into the ground by pressing the base 2, and the device is fixed as a whole. Then the motor 1 is started, and its output shaft pulls the tooth plate 64 through the derivation component 4 to gradually extend outward;

[0048] At the same time, the tooth plate 1 64 will also drive one end of the sampling plate 63 to move at the same time, and force the outer side of the sampling plate 63 to dig the inner wall of the hole. The hydraulic rod 67 is controlled by the computer end. When the device is in working state, the computer end controls the hydraulic rod 67 to be in a free telescopic state. When the tooth plate 1 64 moves outward, the teeth on its side will press the teeth on the side of the hydraulic rod 67. Since the teeth are all inclined, the tooth plate 1 64 can easily press the tooth plate 2 66 to move and compress the spring telescopic rod 2 69. Then the spring telescopic rod 2 69 bounces the tooth plate 2 66 to mesh with the tooth plate 1 64 again, and the inclined teeth can prevent the tooth plate 1 64 from retracting, thereby fixing the position of the sampling plate 63 and enabling better digging and sampling work.

[0049] It should also be noted that the motor 1 will also drive the sampling assembly 6 to rotate as a whole through the derivation assembly 4, so that the outer side of the sampling plate 63 can better dig the ore on the inner wall of the hole. The sampling plate 63 is arc-shaped and in a continuous rotating state, so that the excavated ore powder can enter the interior of the sampling tube 61 through the arc surface. At the same time, the sampling assembly 6 at the lower end will also perform sampling work, and it is always located at the same horizontal plane as the upper sampling plate 63. During the continuous digging and extension process, the inner wall of the hole will be concave, and the powder excavated by the upper sampling plate 63 will not fall too much on the upper side of the lower sampling plate 63, so that the device can sample ores at different levels, while improving the quality of the sampling work;

[0050] After the device has finished working, the hydraulic rod 67 can be controlled to retract through the computer end, and the spring telescopic rod 2 69 can be forcibly compressed. At this time, the tooth plate 2 66 no longer limits the position of the tooth plate 1 64, and the tension spring 68 will pull the tooth plate 1 64 back to the original position. Similarly, the sampling component 6 is in the initial state at this time, and the device can be taken out, which further improves the convenience of the device operation;

[0051] It should also be noted that the number of deduction components 4, docking components 5, sampling components 6 and power transmission components 7 is not specified, and the specific number needs to be changed according to actual usage, but every two deduction components 4 must be connected using a docking component 5 to ensure the stability of the device.

[0052] like Figures 1 to 5 As shown, the upper end derivation component 4 also includes a threaded column 42 connected to the inside of the limit shell 41 by a bearing, the threaded column 42 is transmission-connected to the output shaft of the motor 1, the outer periphery of the threaded column 42 is threadedly connected to two symmetrically arranged connecting blocks 43, the two connecting blocks 43 are respectively hinged with a crushing shaft 47 through a damper 44, and a cylindrical protrusion is also provided at the bottom of the threaded column 42, and a splitting cylinder 49 is provided on the outer periphery of the cylindrical protrusion. Two telescopic rods 46 are symmetrically arranged on the outer periphery of the splitting cylinder 49, and the crushing shaft 47 is rotatably installed on the telescopic end of the telescopic rod 46.

[0053] The derivation assembly 4 also includes two guide rods 40 movably arranged at the bottom of the two crushing shafts 47. The guide rod 40 moves between any two guide rods 65. The guide rod 65 is inclined. The upper sampling tube 61 is fixed to the bottom of the upper threaded column 42.

[0054] The telescopic rod 46 movably penetrates the limit shell 41, and the crushing shaft 47 is movably arranged on the side of the telescopic rod 46. The crushing shaft 47 is hinged to the damper 44 through a universal joint. A metal bellows 48 is arranged at the hinge between the damper 44 and the crushing shaft 47. Metal strips 45 are arranged at equal angles around the outer periphery of the movable end of the damper 44. Two vertical grooves for the movement of the connecting block 43 are symmetrically opened on the outer periphery of the limit shell 41. The threaded column 42 is transmission-connected to the crushing shaft 47 through the power transmission component 7.

[0055] The above scheme is adopted: the limit shell 41 is fixed in the ground through the base 2 and the positioning rod 3, the output shaft of the motor 1 drives the threaded column 42 to rotate, and since the connecting block 43 moves inside the vertical groove, the threaded column 42 will drive the connecting block 43 to descend, and push the crushing shaft 47 and the guide rod 40 to gradually move outward through the damper 44, Figure 5It can be seen from the guide rod 1 40 and the guide rod 2 65 that when the guide rod 2 65 rotates as a whole, the outer periphery of the guide rod 1 40 will contact the guide rod 2 65, but because the guide rod 1 40 is in a slow moving state and the guide rod 2 65 is inclined, the guide rod 1 40 can also guide the tooth plate 1 64 to extend outward through the inclined guide rod 2 65 while moving, so that the sampling component 6 can smoothly perform the sampling work, and the outer periphery of the crushing shaft 47 continues to contact the inner wall of the hole, and the vibration generated by the excavation of the sampling component 6 will eventually be weakened by the damper 44, so that the ore powder on the inner wall of the hole will not fall too much and affect the sampling work of the lower end sampling component 6, further improving the sampling quality of the device while ensuring the stability of the device operation;

[0056] It should be noted that the threaded column 42 also drives the crushing shaft 47 to rotate through the power transmission component 7, and then the crushing shaft 47 drives the movable end of the damper 44 to rotate through the universal joint. The metal strip 45 on the damper 44 digs the ore on the inner wall of the hole during the rotation process, further improving the sampling efficiency, and the damper 44 will not be blocked by the inner wall of the hole when deducing the crushing shaft 47;

[0057] When the metal strip 45 is being excavated, the metal bellows 48 will also prevent the powder from entering the inner wall of the universal joint, thereby damaging it, and indirectly reducing the time and cost of subsequent device maintenance.

[0058] like Figure 1 , Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the power transmission assembly 7 includes a chain 71 which is transmission-connected to the outer periphery of the threaded column 42, and the bottom of the upper end limit shell 41 is located on one side of the crushing shaft 47 and has two reversing rollers 72 movably mounted thereon. A bidirectional spring telescopic rod 73 is fixedly mounted on the bottom of the upper end limit shell 41, and each of the two movable ends of the bidirectional spring telescopic rod 73 is provided with a reversing roller 2 74.

[0059] The chain 71 is respectively connected to the two reversing rollers 1 72 and the reversing roller 2 74 , and the chain 71 is connected to the crushing shaft 47 . Each group of power transmission components 7 has two and are symmetrically arranged at the bottom of the limiting shell 41 .

[0060] The above solution is adopted: the threaded column 42 drives the crushing shaft 47 to rotate and perform the digging work through the chain 71. When the position of the crushing shaft 47 moves, the length of the chain 71 outside the limiting shell 41 increases, and the two-way spring telescopic rod 73 will be compressed, so that the chain 71 can still transmit power.

[0061] like Figure 1 , Figures 10 to 12As shown, the docking assembly 5 includes a docking ring 51 fixed to the outer periphery of the lower end limiting shell 41, and the outer periphery of the upper end limiting shell 41 is elastically connected to a plurality of guide plates 52 through a spring telescopic rod 53 arranged at equal angles in the annular direction, and a positioning rod 55 is arranged at the bottom of each guide plate 52.

[0062] The docking assembly 5 further includes a plurality of positioning holes 54 circumferentially formed on the docking ring 51 . The number and size of the positioning holes 54 are adapted to each positioning rod 55 . The side surface of the guide plate 52 is inclined.

[0063] The above scheme is adopted: the guide plate 52 is pushed down by the spring telescopic rod 1 53, so that the positioning rod 2 55 is always located inside the positioning hole 54, and the guide plate 52 can only slide longitudinally outside the upper limit shell 41, and the upper limit shell 41 is fixed to the ground through the base 2 and the positioning rod 1 3. At this time, the two limit shells 41 are both in a fixed state, and the threaded column 42 at the lower end is fixed to the bottom of the upper extension plate 62, and the upper extension plate 62 is transmission-connected with the upper threaded column 42, which makes the initial state and working state of the lower derivation component 4 the same as the upper derivation component 4, so that the device can work normally;

[0064] When the upper sampling assembly 6 is working, the sampling plate 63 and the tooth plate 64 are in a continuous rotating state. It should be noted that the rotation of the tooth plate 64 will contact the inclined surface of the guide plate 52 and push the guide plate 52 up through the inclined surface. At this time, the spring telescopic rod 1 53 is compressed, and the positioning rod 2 55 is no longer located inside the positioning hole 54, but the other guide plates 52 are still in the initial position, so that the docking assembly 5 can also fix the two limit shells 41, thereby ensuring the stability of the device operation.

[0065] The working principle and use process of the present invention:

[0066] Use drilling equipment to drill holes in the ground. It should be noted that several positioning rods 3 form a circle, and the inner diameter of the hole should be smaller than the diameter of the circle formed by the positioning rods 3 and larger than the outer diameter of the docking assembly 5. When the designated position of the hole is reached, the device can be placed in the hole, and the positioning rods 3 are inserted into the ground by pressing the base 2, and the device is fixed as a whole, and then the motor 1 is started;

[0067] The output shaft of the motor 1 drives the threaded column 42 to rotate. Since the connecting block 43 moves inside the vertical groove, the threaded column 42 will drive the connecting block 43 to descend, and push the crushing shaft 47 and the guide rod 40 to gradually move outward through the damper 44. Figure 5It can be seen from the guide rod 1 40 and the guide rod 2 65 that when the guide rod 2 65 rotates as a whole, the outer periphery of the guide rod 1 40 will contact the guide rod 2 65, but because the guide rod 1 40 is in a slow moving state and the guide rod 2 65 is inclined, the guide rod 1 40 can move while guiding the tooth plate 1 64 to extend outward through the inclined guide rod 2 65;

[0068] Tooth plate 1 64 drives one end of the sampling plate 63 to move at the same time, and the hydraulic rod 67 is controlled by the computer. When the device is in working state, the computer controls the hydraulic rod 67 to be in a free telescopic state. When tooth plate 1 64 moves outward, the teeth on its side will press the teeth on the side of the hydraulic rod 67. Tooth plate 1 64 can easily press tooth plate 2 66 to move and compress spring telescopic rod 2 69. Then spring telescopic rod 2 69 bounces tooth plate 2 66 to mesh with tooth plate 1 64 again, and the inclined teeth can prevent tooth plate 1 64 from retracting. The threaded column 42 drives the sampling assembly 6 to rotate and forces the sampling plate 63 to dig the inner wall of the hole, and finally the powder falls into the interior of the sampling tube 61.

[0069] The threaded column 42 also drives the crushing shaft 47 to rotate through the chain 71, and then the crushing shaft 47 drives the movable end of the damper 44 to rotate through the universal joint. The metal strip 45 on the damper 44 digs the ore on the inner wall of the hole during the rotation process;

[0070] When the upper sampling assembly 6 is working, the sampling plate 63 and the tooth plate 64 are in a continuous rotating state. As the tooth plate 63 rotates, it will contact the inclined surface of the guide plate 52 and push the guide plate 52 up through the inclined surface. At this time, the spring telescopic rod 1 53 is compressed, and the positioning rod 2 55 is no longer located inside the positioning hole 54, but the other guide plates 52 are still located in the initial position, so that the docking assembly 5 can also be fixedly connected to the two limit shells 41, thereby ensuring the stability of the device operation.
