[0029] The utility model provides a mudstone sampling device 100 for geological exploration.

[0030] See also Figure 1-Figure 6 In one embodiment of the utility model, the mudstone sampling device 100 for geological exploration includes a driving member 10, a sampling member 40, two fixed chassis 30 and a movable plate 20, wherein the two fixed chassis 30 are spaced a certain distance apart, and the two fixed chassis 30 are both provided with sliding rods 31, and the movable plate 20 is sleeved on the two sliding rods 31 and can move along the sliding rods 31, and a connecting plate 33 is provided on the top of the sliding rod 31, and handles 34 are provided on both sides of the connecting plate 33, so that people can hold the device stably; the driving member 10 is installed on the connecting plate 33, and its output end is connected to the movable plate 20, and the sampling member 40 is installed at the lower end of the movable plate 20, facing the ground, and when the movable plate 20 is driven by the driving member 10, it drives the sampling member 40 to move downward along the sliding rod 31, so that the sampling member 40 extends into the mudstone for sampling.

[0031] In this embodiment, the fixed chassis 30 can be made of 304 stainless steel and have a certain weight to stabilize the entire device. A barb 32 is provided at the bottom of the fixed chassis 30. The barb 32 can be made of 304 stainless steel, with its tip facing the ground, which can further improve the grip of the device. The sliding rod 31 is a cylindrical rod made of aluminum profiles. The number of the driving members 10 is two. The two driving members 10 can make the moving member 20 more balanced and more powerful. The driving member 10 can be an electric push rod, which can drive the moving plate 20 to move by connecting to an external power supply, and can drive the sampling member 40 to extend into the mudstone for sampling, and when the driving member 10 retracts, the sampling member 40 retracts with the driving member 10, detaches from the ground, and completely preserves the underground mudstone in the internal space of the sampling member 40.

[0032] In one embodiment of the utility model, the sampling member 40 includes an outer shell 41 and an inner tube 42, the inner tube 42 is fixed in the outer shell 41, and pulling members 43 are respectively provided on both sides of the inner tube 42, and flip plates 44 are respectively provided on both sides of the opening of the outer shell 41, and the pulling member 43 is connected to the flip plate 44, and a plurality of fixing platforms 46 are respectively provided on both sides of the inner tube 42, and each fixing platform 46 is provided with a limiting hole 47, and the pulling member 43 is connected to the flip plate 44 through the limiting hole 47.

[0033] Two first through holes 48 are formed at the upper end of the shell 41, and two second through holes 21 are formed on the movable plate 20 corresponding to the first through holes 48. The first through holes 48 are aligned with the second through holes 21. The upper end of the pulling member 43 passes through the first through holes 48 and the second through holes 21 and is exposed above the movable plate 20. A lifting member 50 is provided above the movable plate 20, and the lifting member 50 is connected to the exposed portion of the pulling member 43.

[0034] In this embodiment, the outer shell 41 is made of aluminum die-casting and has a certain compressive strength. The inner tube 42 is a hollow cylindrical tube made of 304 stainless steel. The pulling member 43 can be an iron wire, and the flip plate 44 is a thin sheet made of stainless steel 304, but is not limited to this; the fixed platform 46 is arranged at intervals along the length direction of the inner tube 42, and the pulling member 43 can only move in the longitudinal direction through the limiting hole 47.

[0035] The housing 41 has a receiving groove 49 inside, the flip plate 44 is installed in the receiving groove 49 , the flip plate 49 is connected to the housing 41 via a latch 45 , and the flip plate 44 can be flipped around the latch 45 . It can be understood that when the output end of the driving member 10 drives the movable plate 20 to move downward, the sampling member 40 moves downward and extends into the mudstone, and the mudstone enters the inner tube 42 from the opening of the outer shell 41. When the movable plate 20 moves to abut against the fixed chassis 30, the driving member 10 is turned off, and then the lifting member 50 is pulled upward. The lifting member 50 drives the pulling member 43 to move upward, and the pulling member 43 pulls the flip plate 44. The flip plates 44 on both sides flip upward to cut off the connection between the mudstone in the outer shell 41, so that the mudstone collected in the inner tube 42 and the underground mudstone fault are connected. At this time, the driving member 10 is driven to retract, driving the sampling member 40 to leave the ground. At this time, a complete mudstone column is collected in the inner tube 42, and the structure of the mudstone will not be damaged during sampling, thereby improving the quality of the sample.

[0036] It should be noted that the outer shell 41 is connected to the movable plate 20 by screws. After sampling, the outer shell 41 and the movable plate 20 are disassembled, and then the mudstone in the inner tube 42 is pushed out by using the corresponding long cylinder to obtain a complete mudstone sample.

[0037] In one embodiment of the utility model, a limiting groove 22 is provided on the movable plate 20, and the limiting groove 22 is located between the two second through holes 21. The upper lifting member 50 is partially installed in the limiting groove 22. An elastic member 60 is provided in the limiting groove 22, and one end of the elastic member 60 is fixedly connected to the bottom of the limiting groove 22, and the other end is connected to the bottom of the upper lifting member 50.

[0038] In this embodiment, the elastic member 60 can be a tension spring, but is not limited to this. The lifting member 50 can be made by injection molding, and its overall shape is "T". The lower end of the lifting member 50 is stuck in the limiting groove 22, which can prevent the lifting member 50 from being separated from the movable plate 20 when the lifting member 50 is lifted; after releasing the lifting member 50, under the pulling force of the elastic member 60, the lifting member 50 returns to the initial position, and at the same time, the pulling member 43 moves downward, and the flip plate 44 retracts into the accommodating groove 49 under the drive of the pulling member 43. There is no need to manually reset the flip plate 44, which is convenient for the next sampling.

[0039] Working principle: the mudstone sampling device 100 for geological exploration is moved to the sampling site, the fixed chassis 30 is inserted into the ground, the barbs 32 are extended into the ground, and the driving member 10 is driven after connecting to an external power source, so that it drives the sampling member 40 to move downward and extend into the ground. During the downward movement, the underground mudstone enters the inner tube 42 from the opening of the outer shell 41. When the movable plate 20 moves to stick to the fixed chassis 30, the driving member 10 is stopped, and then the lifting member 50 is lifted, so that the pulling member 43 pulls the flip plate 44 to flip, cutting off the connection between the mudstone in the outer shell 41, so that the mudstone collected in the inner tube 42 and the underground mudstone fault, at this time, the driving member 10 is driven to retract, driving the sampling member 40 to leave the ground, and at this time, a complete mudstone column is collected in the inner tube 42.

All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
