Description

Technical Field

[0001] The invention belongs to the technical field of sampling tools and relates to a detection sampling device for weathered granite. Background Art

[0002] Weathered granite is a type of rock formed due to long-term influence of natural environmental factors such as temperature changes, water erosion and biological activities. Its characteristics include inconsistent particle size, significant changes in hardness and complex mineral composition. In the process of geological exploration, it is often necessary to sample weathered granite.

[0003] At present, when sampling weathered granite, the main sampling methods are divided into manual and mechanical. Manual sampling tools include geological hammers, shovels and core tubes, which are suitable for preliminary geological surveys and sampling of softer strata. For deeper strata, mechanical equipment such as rotary drills and impact drills are usually used for drilling and sampling. However, when existing devices are used to sample rock strata at a fixed depth, it is difficult to accurately and effectively cut off the rock samples at the required depth due to the inconsistent weathering degree and hardness of rock samples at different depths.

[0035] like Figure 6-Figure 8 As shown, the cutting mechanism includes a rotating sleeve 72, a cutting knife 73, a sliding shaft 74 and a convex shaft 75. A plurality of mounting grooves 71 are evenly spaced along the circumferential direction at the lower inner portion of the sampling tube 55. The number of the mounting grooves 71 is consistent with the number of the gas injection grooves 58. The mounting grooves 71 are communicated with the gas injection grooves 58. The lower inner portion of the mounting groove 71 is rotatably connected to the rotating sleeve 72. The lower portion of the rotating sleeve 72 is connected to the cutting knife 73. The cutting knife 73 can be stored in the inner wall of the sampling tube 55. The rotation of the rotating sleeve 72 can drive the cutting knife 73 to rotate. When the cutting knife 73 rotates, it can move into the sampling tube 55, so as to cut the granite in the sampling tube 55. A sliding shaft 74 is slidably connected in the mounting groove 71, and a convex shaft 75 is connected to the lower part of the sliding shaft 74. A guide groove 76 is provided on the inner wall of the rotating sleeve 72, and the convex shaft 75 is located in the guide groove 76, so that the convex shaft 75 can squeeze the guide groove 76 when moving, thereby driving the rotating sleeve 72 to rotate.

[0036] like Fig. 9As shown, it also includes a gas injection mechanism, which includes a connecting frame 81, an air guide frame 82, an air injection pipe 83 and a connecting frame 84. A plurality of connecting frames 81 are evenly spaced and connected to the bottom of the connecting casing 52, and an air guide frame 82 is connected between the plurality of connecting frames 81. The air guide frame 82 is rotatably sealed and connected to the lower portion of the connecting machine head 53. The position of the rotating seal is the contact position between the connecting machine head 53 and the air guide frame 82. A connecting frame 84 is connected to the lower portion of the connecting machine head 53. When the guide sleeve 54 is connected to the connecting machine head 53, the connecting frame 84 covers the air guide groove 57. Through grooves are evenly spaced along the circumferential direction at the lower portion of the connecting machine head 53. Both ends of the through grooves are respectively connected to the air guide frame 82 and the connecting frame 84. An air injection pipe 83 is provided on the air guide frame 82.

[0037] When it is necessary to sample granite, the present sampling device can be used. In the initial state, the telescopic rod of the electric push rod 43 is in an extended state. When in use, the frame 1 is first moved to the desired sampling position through the mobile crawler 3, and then the drive motor 51 can be controlled to operate to drive the connecting head 53 to rotate. When the connecting head 53 rotates, it can drive the guide sleeve 54, the sampling tube 55 and the drill bit 6 to rotate. At this time, the telescopic rod of the electric push rod 43 is retracted to drive the lifting frame 42 to move downward. When the lifting frame 42 moves downward, it can drive the drive motor 51, the guide sleeve 54, the sampling tube 55 and the drill bit 6 to move downward together. When the drill bit 6 moves downward, it can drill into the granite layer, and the granite will enter the sampling tube 55 and the guide sleeve 54 in turn, and the granite can be sampled through the sampling tube 55; when the sampling tube 55 moves down to the desired sampling depth, the gas injection The tube 83 is connected to the high-pressure air pump, and then air is injected into the air injection tube 83 through the high-pressure air pump. The gas in the air injection tube 83 will be injected into the mounting groove 71 through the air guide groove 1 57, the ventilation groove 56, the air guide groove 2 59 and the air injection groove 58. The gas in the mounting groove 71 will squeeze the sliding shaft 74 to move downward. When the sliding shaft 74 moves downward, it drives the convex shaft 75 to move downward. When the convex shaft 75 moves downward, it will squeeze the guide groove 76, thereby driving the rotating sleeve 72 to rotate. When the rotating sleeve 72 rotates, it will drive the cutting knife 73 to rotate. When the cutting knife 73 rotates, it can contact the granite and cut the granite. At this time, the telescopic rod of the electric push rod 43 is controlled to extend to drive the lifting frame 42 to move up, so that the sampling tube 55 and the guide sleeve 54 can be taken out, thereby achieving the effect of sampling the granite, and the granite can be automatically cut off after the sampling is completed, thereby improving the sampling efficiency.

[0038] like Figure 9-12As shown, it also includes a crushing mechanism, which includes a turbine blade disk 91, a crushing tool 92, a solenoid valve 1 93, a cone 94, a solenoid valve 2 95 and an air guide 96. The connecting head 53 is evenly spaced with a plurality of openings for discharging samples. The upper part of the sampling tube 55 is rotatably connected to the turbine blade disk 91, and the crushing tool 92 is connected to the turbine blade disk 91. The upper part of the gas injection groove 58 is provided with a solenoid valve 1 93. The upper part of the sampling tube 55 is evenly spaced with a plurality of air guide tubes 96. One end of the air guide pipe 96 extends into the air guide groove 59, and the other end of the air guide pipe 96 is aligned with the turbine blade disk 91. The part of the air guide pipe 96 located in the air guide groove 59 is provided with a solenoid valve 95. The top of the connecting head 53 is connected to a cone 94. The upper part of the sampling tube 55 is evenly spaced with return grooves 97. One end of the return groove 97 is aligned with the outside of the turbine blade disk 91, and the other end of the return groove 97 extends to the upper side of the sampling tube 55, so that excess gas at the turbine blade disk 91 can be discharged through the return groove 97.

[0039] During the sampling process, the sample in the rock layer moves upward from the sampling tube 55 to the guide sleeve 54, while the sample in the upper layer does not need to be moved. Before the sample enters the guide sleeve 54, it will contact the crushing tool 92. When the gas is injected through the gas injection pipe 83, the gas will pass through the ventilation groove 56 and the gas guide groove 1 57 to enter the gas guide groove 2 59. At this time, the solenoid valve 1 93 can be controlled to close, and then the solenoid valve 2 95 can be controlled to open. When the solenoid valve 2 95 is opened, the gas in the gas guide groove 2 59 will be injected into the turbine blade through the gas guide pipe 96. The turbine blade disk 91 is in the disk 91, thereby driving the turbine blade disk 91 to rotate. When the turbine blade disk 91 rotates, it will drive the crushing tool 92 to rotate, so that the unnecessary samples can be crushed. Then, as the guide sleeve 54 descends, the connecting head 53 is driven to move downward to contact the sample, so that the sample is squeezed by the cone cylinder 94 and discharged through the opening on the side of the connecting head 53. In this way, the unnecessary samples can be automatically crushed and discharged, which is more convenient to operate. When it is necessary to control the cutting knife 73 to perform cutting work, the solenoid valve 93 can be opened.

[0040] like Fig.13 and Fig.14 As shown, a rubber sleeve 10 is also included. The rubber sleeve 10 is connected to the lower part of the sampling tube 55. A plurality of air holes 11 are evenly spaced apart at the lower part of the sampling tube 55. One end of the air hole 11 extends into the mounting groove 71, and the other end of the air hole 11 is aligned with the rubber sleeve 10.

[0041] Initially, the sliding shaft 74 blocks the air hole 11, and after the sliding shaft 74 moves downward, the sliding shaft 74 no longer blocks the air hole 11. At this time, the gas in the mounting groove 71 will be injected into the rubber sleeve 10 through the air hole 11, causing the rubber sleeve 10 to expand. The expansion of the rubber sleeve 10 can compress the sample to prevent the internal sample from falling when the sampling tube 55 moves upward.

[0042] like Fig.15 As shown, a sponge gasket 12 is also included. The sponge gasket 12 is arranged in the second air guide groove 59. The sponge gasket 12 can isolate mud and sand to prevent mud and sand from entering the second air guide groove 59 during the sampling process.

[0043] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein.
