Description

Technical Field

[0001] This utility model relates to the field of geological exploration equipment technology, and in particular to a sampling device for geological structure exploration. Background Technology

[0002] In engineering construction, such as the construction of highways, railways, and dams, surveying and sampling can provide information on foundation stability, soil and rock mechanical properties, and assess potential geological hazard risks, such as landslides and debris flows. By analyzing the extracted samples, the lithology, thickness, bedding, and other characteristics of the strata can be determined, thereby inferring the morphology, scale, and spatial distribution of geological structures, such as identifying anticlines, synclines, or faults.

[0003] In particular, pit sampling involves excavating pits and trenches on the surface to directly expose geological bodies, and then taking samples from within the pits. This method is suitable for the exploration of surface and shallow geological structures, such as the study of fault fracture zones and landslides. It allows for direct observation of the details of geological structures. When sampling, a grid method is used (a grid is drawn on the exposed part of the ore body, and ore blocks are chiseled out evenly according to the grid spacing) to obtain rock samples. This method can fully cover the exposed part of the rock body, avoiding omissions that may be caused by sampling only from a local area. This allows the collected samples to cover the characteristics of different locations in the rock body, and more comprehensively reflect the overall situation of the rock layer.

[0004] However, in actual sampling, when using the grid method, staff need to enter the test pit and draw grid lines on the rock surface, and then chisel the rock within the grid to take samples, which significantly reduces the convenience of sampling. Therefore, this application proposes a sampling device for geological structure exploration that can facilitate sampling. Utility Model Content

[0005] The purpose of this invention is to address the problem in the prior art that requires manually drawing grid lines and manually chiseling rock masses for sampling, and to propose a sampling device that facilitates sampling for geological structure exploration.

[0006] The technical solution of this utility model: A sampling device for geological structure exploration, comprising two support bases, with a bracket fixedly installed between the two support bases, and further comprising:

[0007] A lifting assembly is fixedly installed on the top of the bracket, and a grid plate is movably installed on the lifting assembly. Several sampling ports are cut into the grid plate.

[0008] The second motor is movably mounted below the bracket, and a drill bit is fixedly mounted on the output end of the second motor. The drill bit is positioned on one side of the matching sampling port.

[0009] Optionally, the lifting assembly includes two symmetrically arranged limiting plates, with a lifting frame slidably mounted between the two limiting plates, and the mesh plate is fixedly installed at the bottom of the lifting frame.

[0010] Optionally, a connecting plate is fixedly installed at the top of the lifting frame, and a first motor is fixedly installed at the top of the two limiting frame plates. A reciprocating screw is fixedly installed at the output end of the first motor, and one end of the reciprocating screw passes through the connecting plate and is threadedly connected to it.

[0011] Optionally, the bracket has an elongated opening, and the bottom end of the grid plate passes through the elongated opening and extends below it.

[0012] Optionally, a first limiting plate and a second limiting plate are fixedly installed at the bottom of the bracket. A plurality of connecting rods are fixedly installed between the first limiting plate and the second limiting plate. A transverse frame plate is movably installed on the plurality of connecting rods. The second motor is fixedly installed on the transverse frame plate.

[0013] Optionally, the first limiting plate has several circular openings, and one end of the drill bit passes through the circular openings and is movably connected to them.

[0014] Optionally, a circular opening is provided on the second limiting plate, and a cylinder is fixedly installed at the bottom of the bracket. The output end of the cylinder passes through the circular opening and is fixedly connected to the transverse frame plate.

[0015] Optionally, a plurality of sample debris collection covers are fixedly installed on the grid plate at a position corresponding to the sampling port. A sealing plate is fixedly installed at the end of the sample debris collection cover away from the grid plate, and a drill bit extension opening is chiseled on the sealing plate.

[0016] Optionally, a handrail is fixedly installed on both of the support bases, and several rollers are rotatably installed on the bottom of the support bases.

[0017] Compared with the prior art, this application includes at least one of the following beneficial technical effects: the grid plate is moved downward by the lifting component. After the grid plate covers the rock wall of the test pit, the second motor is moved to one side of the rock wall by the cylinder to ensure that the drill bit can chisel the rock wall. Then the chiseled sample fragments fall into the sample fragment collection hood. There is no need for staff to enter the test pit to draw grid lines or to manually chisel the rock wall for sampling, which effectively improves the convenience of sampling.

[0031] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] Example

[0033] like Figures 1-4As shown, this utility model proposes a sampling device for geological structure exploration, comprising two parallel support bases 1, a bracket 3 fixedly installed between the two support bases 1, a lifting assembly 4 fixedly installed on the top of the bracket 3, a first motor 6 fixedly installed on the top of the lifting assembly 4, a reciprocating screw 61 fixedly installed at the output end of the first motor 6, one end of the reciprocating screw 61 passing through and threadedly connected to a lifting frame 42 provided on the lifting assembly 4, ensuring that the first motor 6 can drive the lifting frame 42 to move up and down; a grid plate 5 is fixedly installed at the bottom of the lifting frame 42, and the grid plate 5 is lifted by the lifting frame 42. The lowering mechanism allows the grid plate 5 to be inserted into the test pit, facilitating its coverage of the inner rock wall. Several second motors 9 capable of lateral movement are movably mounted at the bottom of the aforementioned bracket 3. A drill bit 91 is fixedly mounted at the output end of each second motor 9. Once the drill bit 91 passes through the sampling port 51 drilled in the grid plate 5, it can chisel the rock wall of the test pit, facilitating sampling. A handrail 7 is fixedly mounted on the top of both support bases 1, and several rollers 2 are rotatably mounted on the bottom of each support base 1. By holding the handrail 7 and using the rollers 2 for assistance, the operator can move the sampling device, facilitating the movement of the grid plate 5 above the test pit.

[0034] Furthermore, the lifting assembly 4 includes two symmetrically arranged limiting plates 41, and the lifting frame 42 is movably installed between the two limiting plates 41, effectively improving the stability of the lifting frame 42 during lifting and moving; a connecting plate 43 is fixedly installed at the top of the lifting frame 42, and one end of the reciprocating screw 61 passes through the connecting plate 43 and is threadedly connected to it, ensuring that the first motor 6 can drive the lifting frame 42 and the grid plate 5 to move stably up and down, and facilitating the adjustment of the height of the grid plate 5.

[0035] Secondly, a long strip opening 31 is cut into the bracket 3, and the bottom end of the grid plate 5 passes through the long strip opening 31 and extends below it. When the grid plate 5 is raised or lowered, a long strip opening 31 is reserved on the bracket 3 at the position corresponding to the grid plate 5, which can prevent the bracket 3 from obstructing the raising or lowering adjustment of the grid plate 5.

[0036] Furthermore, a first limiting plate 32 and a second limiting plate 34 are fixedly installed at the bottom of the bracket 3. Several connecting rods 35 are fixedly installed between the first limiting plate 32 and the second limiting plate 34. A transverse moving frame plate 33 is movably installed on the several connecting rods 35. The second motor 9 is fixedly installed on the transverse moving frame plate 33. The connecting rods 35 limit the transverse moving frame plate 33 in the vertical direction, ensuring that the second motor 9 can move laterally with the transverse moving frame plate 33 stably. Several circular openings are drilled on the first limiting plate 32. One end of the drill bit 91 passes through the circular opening and is movably connected to it. After the second motor 9 moves to one side of the grid plate 5, it ensures that the drill bit 91 can pass through the first limiting plate 32 and be inserted into the sampling port 51, which facilitates the drilling and sampling of the test pit rock wall.

[0037] Secondly, a circular opening is cut into the second limiting plate 34, and a cylinder 8 is fixedly installed at the bottom of the bracket 3. The output end of the cylinder 8 passes through the circular opening and is fixedly connected to the transverse frame plate 33. The cylinder 8 can push the transverse frame plate 33 to move laterally, which facilitates the adjustment of the position of the second motor 9 in the horizontal direction.

[0038] It is worth noting that a sample debris collection cover 52 is fixedly installed on the grid plate 5 at a position corresponding to the sampling port 51. A sealing plate 53 is fixedly installed at the end of the sample debris collection cover 52 away from the grid plate 5. A drill bit extension port 54 is drilled on the sealing plate 53. When the second motor 9 moves to one side of the grid plate 5, the drill bit 91 passes through the drill bit extension port 54 and extends to the sampling port 51, and then can be used to drill and sample the rock wall of the test pit. At this time, the sample debris falling on the rock wall falls into the sample debris collection cover 52, which facilitates the collection of sample debris.

[0039] In this embodiment, the operator first holds the handrail 7, and with the assistance of the roller 2, the sampling device can be pushed to the test pit. When the grid plate 5 is suspended above the test pit wall, the first motor 6 drives the lifting frame 42 and the grid plate 5 to move downward, and the horizontal position of the sampling device is finely adjusted to ensure that the grid plate 5 can be attached to the rock wall inside the test pit. At this time, the operator holds the handrail 7 and ensures that the sampling device stops moving. The cylinder 8 drives the second motor 9 to move to one side of the grid plate 5. When the drill bit 91 passes through the sample fragment collection cover 52 and extends to the sampling port 51, the second motor 9 drives the drill bit 91 to rotate, which can chisel the rock wall, making it convenient to collect sample fragments. There is no need for the operator to enter the test pit to draw grid lines on the rock wall, nor is there a need for the operator to manually chisel the rock wall for sampling, which improves the convenience of sampling.

[0040] After the rock wall of the exploratory pit is broken up, the debris falls into the sample debris collection hood 52. After the sampling operation is completed, the cylinder 8 drives the second motor 9 to move away from the grid plate 5. When the drill bit 91 is pulled out from the sample debris collection hood 52, the first motor 6 drives the grid plate 5 to move upward, making it easier to take out the collected sample from the exploratory pit. The staff pushes the sampling device away from the exploratory pit. At this time, the sample debris collection hood 52 on the grid plate 5 is located below the bracket 3. The staff can take out the sample debris from the sampling port 51, which facilitates the collection of sample debris and improves the convenience of sample collection.

[0041] The above specific embodiments are merely several optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
