Description

Technical Field

[0001] The present invention relates to the technical field of sampling drills, and specifically to an impact geological sampling drill. Background Art

[0002] The impact geological sampling drill generates a powerful impact force through a mechanical device or a hydraulic or pneumatic device, so that the drill bit acts on the ground with a high-energy impact action to break the ground for drilling.

[0003] The existing impact geological sampling drills can already achieve layered sampling of the ground. However, the method used is to directly stuff the soil of the entire depth into the sampling pipe, then open the pipe, take out the soil sample collected in the pipe, and then manually put the soil at different depths into small containers one by one and send it to the detection place for detection. This sampling method has multiple drawbacks: 1. It is necessary for people to manually separate the soil samples at different depths in the sampling pipe, put them into containers, and send them to the detection place, with low efficiency; 2. It is impossible to sample multiple points of the surrounding soil, and only single-point sampling can be carried out at one position, which is not convenient for comparative experiments; 3. When sampling multiple points of soil at the same depth, if the soil is relatively hard, most of the soil is in a caked state, and it is difficult to collect the hard caked soil into the sampling device.

[0004] Based on this, a kind of impact geological sampling drill is provided now, which can eliminate the drawbacks of the existing device. Summary of the Invention

Detailed implementation manners

[0034] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0035] In one embodiment, as Figures 1-9 shown, an impact type geological sampling drill includes a fixed bottom plate 1, a top plate 2, a guide frame 4, a multi-point sampling assembly 12 for layering, and a drilling assembly 44. Four pairwise opposite guide frames 4 are fixedly connected between the fixed bottom plate 1 and the top plate 2;

[0036] The drilling assembly 44 includes a drill barrel 6 and a lifting plate 7. Two symmetric threaded rods 5 are connected between the top plate 2 and the fixed bottom plate 1 through bearings. Both of the two threaded rods 5 are threadedly connected to the lifting plate 7. The lower surface of the lifting plate 7 is connected to the drill barrel 6 through a plurality of telescopic rods. An impactor 8 is arranged between the drill barrel 6 and the lifting plate 7. The lifting plate 7 is slidably connected to the side wall of the guide frame 4. Two symmetric motors 3 are fixedly connected to the upper surface of the top plate 2 through brackets. The output end of the motor 3 is connected to the threaded rod 5;

[0037] The multi-point sampling assembly 12 for layering is arranged in the drill barrel 6 and is used for simultaneously sampling multiple points of soil at different depths.

[0038] First, fix the fixed bottom plate 1 at the position where drilling and sampling are required. Start the two motors 3. The motors 3 drive the threaded rods 5 to rotate. The rotation of the threaded rods 5 drives the lifting plate 7 to descend. At the same time, start the impactor 8. The impactor 8 drives the drill barrel 6 to vibrate, and the drill barrel 6 continuously penetrates into the ground.

[0039] In one embodiment, the layered multi-point sampling assembly 12 includes a hydraulic cylinder 10, a first connecting rod 13, and a sampling box 14. A lifting cross rod cavity is formed in the drill pipe 6. The inner top wall of the lifting cross rod cavity is fixedly connected with the hydraulic cylinder 10. The output end of the hydraulic cylinder 10 is fixedly connected with a lifting cross rod 11. The lifting cross rod 11 is slidably connected with the inner side wall of the lifting cross rod cavity. A plurality of sampling box grooves are formed in the side wall of the drill pipe 6. All the plurality of sampling box grooves communicate with the lifting cross rod cavity. A plurality of first connecting rods 13 evenly distributed in a circumferential manner are rotatably connected to the side wall of the lifting cross rod 11 through pin shafts. The inner side wall of the sampling box groove is slidably connected with a sampling box 14. A connecting plate 29 is fixedly connected to the side wall of the sampling box 14. The connecting plate 29 and the first connecting rod 13 are rotatably connected through a pin shaft. The upper surface of the sampling box 14 is rotatably connected with a rotating box 16 through a bearing. A sampling cylinder groove is arranged on the upper surface of the rotating box 16. A sampling cylinder 25 is detachably arranged in the sampling cylinder groove.

[0040] After the drill pipe 6 descends to a specified depth, the hydraulic cylinder 10 is started. The hydraulic cylinder 10 drives the lifting cross rod 11 to descend. The descent of the lifting cross rod 11 drives a plurality of sampling boxes 14 to extend out of the sampling box grooves through a plurality of first connecting rods 13, so that soil falls into the sampling cylinder 25.

[0041] Four sampling boxes 14 at the same depth simultaneously sample four points at the same layer for comparative experiments, improving the accuracy of sampling detection and making the detection data more reliable.

[0042] In one embodiment, a soil breaking structure 45 is arranged in the sampling box 14. The soil breaking structure 45 includes a rotary drill bit 15. The inner bottom wall of the sampling box groove is fixedly connected with a fixing plate 17. A non-self-locking screw rod 26 is fixedly connected to the side wall of the fixing plate 17. The non-self-locking screw rod 26 penetrates through the sampling box 14. A threaded cylinder 18 is connected to the inner side wall of the sampling box 14 through a bearing. The threaded cylinder 18 is in threaded connection with the non-self-locking screw rod 26. The threaded cylinder 18 is fixedly connected with a first gear 19. A first rotating shaft 20 is connected to the inner side wall of the sampling box 14 through a bearing. One end of the first rotating shaft 20 located outside the sampling box 14 is fixedly connected with the rotary drill bit 15. A second gear 21 is fixedly connected to the part of the first rotating shaft 20 located inside the sampling box 14. The second gear 21 meshes with the first gear 19.

[0043] When the sampling box 14 moves out of the sampling box groove, the threaded cylinder 18 cooperates with the non-self-locking screw rod 26 and rotates. The rotation of the threaded cylinder 18 drives the first gear 19 to rotate. The first gear 19 drives the first rotating shaft 20 to rotate through the second gear 21. The first rotating shaft 20 drives the rotary drill bit 15 to rotate, enabling the rotary drill bit 15 to break harder soil and allowing the sampling box 14 to smoothly extend out of the sampling box groove.

[0044] In one embodiment, a material taking structure 46 is arranged in the sampling box 14. The material taking structure 46 includes a pressing block 27, an extrusion box 28, and a lifting guide rail 31. The upper surface of the sampling box 14 is fixedly connected through penetration with the extrusion box 28. The inner side wall of the extrusion box 28 is slidably connected through penetration with the pressing block 27. A spring is fixedly connected between the pressing block 27 and the inner bottom wall of the extrusion box 28. The sampling box 14 is fixedly connected with a liquid box 24 through a bracket. The liquid box 24 and the extrusion box 28 are communicated through a connecting pipe. The liquid box 24 and the lower surface of the rotating box 16 are connected through a bearing. A chamber is formed between the liquid box 24 and the lower surface of the rotating box 16. Eight pairs of opposite lifting block cylinders 32 are fixedly connected to the inner bottom wall of the rotating box 16. The lifting block cylinders 32 are communicated with the chamber formed by the liquid box 24 and the rotating box 16. Hydraulic oil is arranged in the liquid box 24 and the extrusion box 28. The top wall of the inner part of the sampling box groove is fixedly connected with an extrusion baffle 47. The extrusion baffle 47 abuts against the pressing block 27;

[0045] The inner side wall of the lifting block cylinder 32 is slidably connected through penetration with a lifting block 33. The upper surfaces of the two lifting blocks 33 are fixedly connected together with the lifting guide rail 31. Six circumferentially uniformly distributed guide cylinders 30 are fixedly connected through penetration with the upper surface of the rotating box 16. The inner side wall of the guide cylinder 30 is slidably connected with a material taking rod 34. Two symmetric chutes are formed in the side wall of the guide cylinder 30. The inner side wall of the chute is slidably connected with a sliding sleeve 48. A sliding block 41 is fixedly connected to the side wall of the sliding sleeve 48. The sliding block 41 is slidably connected with the track of the lifting guide rail 31. The sliding sleeve 48 is connected with a second rotating shaft 43 through a bearing. The second rotating shaft 43 and the material taking rod 34 are rotationally connected through a bearing.

[0046] During the process of the sampling box 14 moving out of the sampling box groove, the pressing block 27 contacts the extrusion baffle 47. The extrusion baffle 47 extrudes the pressing block 27. The pressing block 27 descends, causing the hydraulic oil in the extrusion box 28 to flow into the cavity formed by the liquid box 24 and the rotating box 16, and then flowing into the lifting block cylinder 32 through the holes, jacking up the lifting block 33. The lifting block 33 jacks up the lifting guide rail 31. During the upward movement of the lifting guide rail 31, the material taking rod 34 is driven through the sliding block 41 to extend to the outside along the inner side wall of the guide cylinder 30, so as to crush the harder soil, facilitate the separation of the harder caked soil, and enable it to smoothly fall into the sampling cylinder 25.

[0047] In one embodiment, a third gear 49 is fixedly connected to one of the second rotating shafts 43. A rack 42 is fixedly connected to the inner side wall of the guiding cylinder 30. The rack 42 meshes with the third gear 49. A vibration block groove is formed in the side wall of the material taking rod 34. A vibration block 35 is slidably connected to the inner side wall of the vibration block groove. A convex block 40 is fixedly connected to the inner side wall of the vibration block groove. A spring is fixedly connected between the convex block 40 and the vibration block 35. A first guide rail 39 is fixedly connected to the inner side wall of the vibration block groove. One end of the second rotating shaft 43 located inside the material taking rod 34 is fixedly connected to a second connecting rod 36. The end of the second connecting rod 36 far from the second rotating shaft 43 is rotatably connected to a third connecting rod 37 through a pin shaft. The end of the third connecting rod 37 far from the second connecting rod 36 is rotatably connected to an impact rod 38 through a pin shaft. The impact rod 38 is slidably connected to the inner side wall of the first guide rail 39.

[0048] While the material taking rod 34 is moving, the third gear 49 and the rack 42 cooperate to rotate. The rotation of the third gear 49 drives the second rotating shaft 43 to rotate. The second rotating shaft 43 drives the second connecting rod 36 to rotate. The second connecting rod 36 drives the third connecting rod 37 to rotate. The third connecting rod 37 drives the impact rod 38 to reciprocate along the first guide rail 39, hitting the vibration block 35, causing the sampling cylinder 25 to vibrate and improving the smashing effect on harder soil.

[0049] In one embodiment, a bevel gear 22 is fixedly connected to the first rotating shaft 20. A bevel gear ring 23 is fixedly connected to the periphery of the rotating box 16. The bevel gear ring 23 meshes with the bevel gear 22.

[0050] While the first rotating shaft 20 is rotating, it drives the bevel gear 22 to rotate. The rotation of the bevel gear 22 drives the bevel gear ring 23 to rotate. The bevel gear ring 23 drives the rotating box 16 to rotate. The rotating box 16 drives the four material taking rods 34 to rotate, performing rotational separation and smashing on harder soil, enabling it to smoothly enter the sampling cylinder 25 and preventing soil clumping from failing to smoothly fall into the sampling cylinder 25.

[0051] In one embodiment, two symmetric guiding plates 9 are fixedly connected to the lower surface of the lifting plate 7 through brackets. The two guiding plates 9 are slidably connected to the drilling cylinder 6.

[0052] The above embodiment discloses an impact type geological sampling drill. Its specific working principle and process are as follows:

[0053] S1: First, fix the fixed bottom plate 1 at the position where drilling and sampling are required. Start the two motors 3. The motors 3 drive the threaded rods 5 to rotate. The rotation of the threaded rods 5 drives the lifting plate 7 to descend. At the same time, start the impactor 8. The impactor 8 drives the drilling cylinder 6 to vibrate, and the drilling cylinder 6 continuously penetrates into the ground;

[0054] S2: After the drill pipe 6 descends to the specified depth, start the hydraulic cylinder 10. The hydraulic cylinder 10 drives the lifting cross bar 11 to descend. The descent of the lifting cross bar 11 drives several sampling boxes 14 to extend out of the sampling box groove through several first connecting rods 13, causing the soil to fall into the sampling cylinder 25;

[0055] The four sampling boxes 14 at the same depth simultaneously sample four points at the same layer for comparative experiments, improving the accuracy of sampling detection and making the detection data more reliable;

[0056] S3: While the sampling box 14 moves out of the sampling box groove, the threaded cylinder 18 cooperates with the non-self-locking screw rod 26 and rotates. The rotation of the threaded cylinder 18 drives the first gear 19 to rotate. The first gear 19 drives the first rotating shaft 20 to rotate through the second gear 21. The first rotating shaft 20 drives the rotary drill bit 15 to rotate, enabling the rotary drill bit 15 to break up harder soil and allowing the sampling box 14 to extend out of the sampling box groove smoothly;

[0057] S4: During the process of the sampling box 14 moving out of the sampling box groove, the pressing block 27 contacts the extrusion baffle 47. The extrusion baffle 47 extrudes the pressing block 27. The descent of the pressing block 27 causes the hydraulic oil in the extrusion box 28 to flow into the cavity formed by the liquid box 24 and the rotating box 16, and then flow into the lifting block cylinder 32 through the holes, jacking up the lifting block 33. The lifting block 33 jacks up the lifting guide rail 31. During the upward movement of the lifting guide rail 31, the feeding rod 34 is driven by the slider 41 to extend along the inner side wall of the guiding cylinder 30 to the outside, breaking up harder soil to facilitate the separation of the harder caked soil and enabling it to fall smoothly into the sampling cylinder 25;

[0058] S5: While the feeding rod 34 moves, the third gear 49 rotates in cooperation with the rack 42. The rotation of the third gear 49 drives the second rotating shaft 43 to rotate. The second rotating shaft 43 drives the second connecting rod 36 to rotate. The second connecting rod 36 drives the third connecting rod 37 to rotate. The third connecting rod 37 drives the impact rod 38 to reciprocate along the first guide rail 39, impacting the vibration block 35 and causing the sampling cylinder 25 to vibrate, improving the effect of breaking up harder soil;

[0059] S6: While the first rotating shaft 20 rotates, it drives the bevel gear 22 to rotate. The rotation of the bevel gear 22 drives the bevel gear ring 23 to rotate. The bevel gear ring 23 drives the rotating box 16 to rotate. The rotating box 16 drives the four feeding rods 34 to rotate, rotating and separating and breaking up harder soil to enable it to smoothly enter the sampling cylinder 25 and prevent the soil from caking and being unable to fall smoothly into the sampling cylinder 25;

[0060] S7: Restart the hydraulic cylinder 10 again. The hydraulic cylinder 10 drives the lifting cross bar 11 to move, causing several sampling boxes 14 to enter the interior of the sampling box. Restart the motor 3 again to drive the drill cylinder 6 to rise. When taking samples, only need to start the hydraulic cylinder 10 and control the moving distance of the hydraulic cylinder 10. The hydraulic cylinder 10 drives several sampling boxes 14 to extend again. However, when taking out the sampling cylinder 25, the extending distance of the sampling box 14 outwards should be less than the extending distance when sampling at the bottom. This is to avoid squeezing the pressing block 27 by squeezing the baffle 47, resulting in the rising of the material taking rod 34 and affecting the disassembly of the sampling cylinder 25.

[0061] Take out several sampling cylinders 25. The sampling cylinders 25 themselves can carry certain marks, such as depth marks, which can be used to record which layer of soil the sampling cylinder 25 samples, facilitating subsequent classification, sorting, and also convenient for subsequent comparative experiments to avoid confusion. After the sampling cylinders 25 are taken out, they can be directly sent to the laboratory for testing, eliminating the need for manual classification and sorting of the samples in the sampling machine again, effectively improving the efficiency of sampling and testing.

[0062] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
