DETAILED DESCRIPTION

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] Combined with Figure 1 As shown, a geological survey and drilling device for geotechnical engineering includes a vehicle plate 1, a frame 2, a rotation drive mechanism 4, a drill rod 7 and a drill 8. The vehicle plate 1 is installed on a vehicle carrier, the frame 2 is hinged on the vehicle plate 1, and a hydraulic cylinder 11 for driving the frame 2 to rotate is provided on the vehicle plate 1. The rotation drive mechanism 4 is provided on the frame 2, and the rotation drive mechanism 4 drives the drill rod 7 and the drill 8 to rotate.

[0027] Combined with Figure 5 , Attachment Figure 6 and attached Figure 7 As shown, the drill 8 includes a sampling barrel 81 and a drill bit 82, the sampling barrel 81 and the drill bit 82 are connected by bolts, a sample storage groove 85 is provided on the inner side of the sampling barrel 81, a plurality of feed ports 86 are evenly arranged on the outer side of the sampling barrel 81, a guide plate 87 is hingedly provided at the feed port 86, a limit platform 88 for limiting the rotation angle of the guide plate 87 is provided on the outer side of the sampling barrel 81, a scraper inclined plate 1 83 and a scraper inclined plate 2 84 are respectively provided on the outer side of the sampling barrel 81 above and below the feed port 86, the scraper inclined plate 1 83 and the scraper inclined plate 2 84 are inclined in opposite directions, and a spiral platform 89 is provided on the inner wall of the sample storage groove 85.

[0028] Working principle of the drill 8: The drill 8 rotates with the drill rod 7 and drills the rock and soil through the drill bit 82. Figure 6In the process, the drill 8 rotates counterclockwise, and the outer side of the guide plate 87 is blocked by the soil layer, so that the guide plate 87 closes the feed port 86. After reaching the sampling layer, the drill 8 rotates clockwise. At this time, the side of the guide plate 87 is blocked by the soil layer and gradually opens. The side of the guide plate 87 scrapes off the soil of the soil layer. The scraper inclined plate 1 83 and the scraper inclined plate 2 84 push the soil to move during the rotation, and limit the soil to the interval near the feed port 86. Then, the soil enters the sample storage groove 85 under the push of the guide plate 87. After the sample storage groove 85 below the feed port 86 is filled, the soil entering from the outside pushes the soil inside the sample storage groove 85 to rotate relative to the sampling tube 81, and through the spiral table 89, the soil inside the sample storage groove 85 can fill the sample storage groove 85 upward, thereby increasing the sampling amount.

[0029] Combined with Figure 1 , Attachment Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, a pressure transmission mechanism 3 is provided on the frame 2, and the pressure transmission mechanism 3 includes a door frame 31, a hydraulic cylinder 2 33 and a transmission rod 36. The transmission rod 36 is rotatably provided on the door frame 31. External support plates 32 are provided on both sides of the bottom of the door frame 31. The output end of the hydraulic cylinder 2 33 is connected to the external support plate 32 to push the door frame 31 to move up and down. The transmission rod 36 is connected to the drill rod 7. The rotation drive mechanism 4 includes a drive box 41 and a turntable 42. The drive box 41 drives the turntable 42 to rotate on the frame 2. The transmission rod 36 is a polygonal column, and the turntable 42 is provided with a through hole adapted to the shape of the transmission rod 36.

[0030] Working principle of the pressure transmission mechanism 3: hydraulic cylinder 2 33 pushes the door frame 31 downward through the outer support plate 32, exerts downward pressure on the transmission rod 36 to facilitate drilling, and the drive box 41 drives the turntable 42 to rotate. The through hole on the turntable 42 cooperates with the polygonal transmission rod 36, so that the turntable 42 drives the transmission rod 36 to rotate, so that the drill 8 can rotate and drill.

[0031] Combined with Figure 4 and attached Figure 5 As shown, a second connecting platform 71 is provided at one end of the drill rod 7, a slot 72 is provided at the bottom of the second connecting platform 71, the same plug block 1 73 and plug block 2 811 are provided at the top of the drill rod 7 and the sampling tube 81, respectively, the plug block 1 73 and the plug block 2 811 are plugged into the slot 72, the second connecting platform 71 is connected to the plug block 1 73 and the plug block 2 811 by bolts, and a connecting platform 1 37 identical to the connecting platform 2 71 is provided at the bottom of the transmission rod 36, the connecting platform 1 37 is plugged into the plug block 1 73 and connected by bolts.

[0032] The connection principle of the transmission rod 36, the drill rod 7 and the sampling tube 81: the transmission rod 36 and the drill rod 7, the drill rod 7 and the sampling tube 81 and the drill rod 7 are all connected to the slot 72 through the plug block 1 73 or the plug block 2 811. The plug block 1 73 and the plug block 2 811 are rectangular, which can realize the forward and reverse rotation of the drill rod 7 and the sampling tube 81.

[0033] Combined with Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, the frame 2 includes a landing seat 21 and a vertical frame 22. The vertical frame 22 is arranged on the landing seat 21. A front slide groove 23 and a side slide groove 24 are arranged on the front side of the vertical frame 22. A fixed platform 34 is arranged on the outer side of the hydraulic cylinder 33. A plurality of sliders 35 are evenly arranged on the rear side of the fixed platform 34. The sliders 35 slide in cooperation with the front slide groove 23. The outer support plate 32 slides in cooperation with the side slide groove 24. A limiting mechanism 5 for limiting the position of the fixed platform 34 in the vertical frame 22 is provided on the vertical frame 22. A winch 12 is provided on the vehicle plate 1. A guide wheel 25 is provided on the top of the frame 2. After the steel rope on the winch 12 passes around the guide wheel 25, it passes through the through hole at the top of the frame 2 and is connected to the outer support plate 32. A clamping plate 6 is symmetrically hinged on the front side of the landing seat 21. The clamping plate 6 clamps the drill rod 7.

[0034] The cooperation principle of the frame 2, hydraulic cylinder 2 33 and limiting mechanism 5 is as follows: the fixed platform 34 and the outer support plate 32 slide in the front slide groove 23 and the side slide groove 24, and the position of the fixed platform 34 is intermittently limited by the limiting mechanism 5 to provide a force fulcrum for the hydraulic cylinder 2 33. When the drill rod 7 needs to be added, the clamping plate 6 clamps the drill rod 7, and then the drill rod 7 is separated from the transmission rod 36. The pressure transmission mechanism 3 is lifted by the winch 12. After the drill rod 7 is connected, the clamping plate 6 is opened and the drilling operation is carried out.

[0035] Combined with Figure 2 , Attachment Figure 3 and attached Figure 4 As shown, the limiting mechanism 5 includes a hydraulic cylinder 3 51 and a push plate 52. The hydraulic cylinder 3 51 is fixed to the rear side of the stand 22. The push plate 52 is slidably arranged in the inner groove of the front slide 23. The output end of the hydraulic cylinder 3 51 is connected to the push plate 52. A plurality of limiting plugs 53 are evenly arranged on the front side of the push plate 52. The limiting plugs 53 are plugged into the gap between the adjacent sliders 35.

[0036] Working principle of the limiting mechanism 5: hydraulic cylinder three 51 pushes the push plate 52 to move horizontally, so that the limiting insert 53 is inserted into the gap between adjacent sliders 35, thereby preventing the fixed platform 34 from moving downward. At this time, hydraulic cylinder two 33 can push the door frame 31 to move downward. After the hydraulic cylinder two 33 reaches the output range, the push plate 52 is reset, and the output end of the hydraulic cylinder two 33 contracts, driving the fixed platform 34 to move downward, and the push plate 52 is pushed in again. In this way, the hydraulic cylinder two 33 with a shorter stroke can adapt to long-distance pushing operations, and also increase the output range of the limited height stand 22.

[0037] During the specific implementation of the utility model, after the vehicle arrives at the designated position, the hydraulic cylinder 11 pushes the frame 2 to stand upright, so that the landing seat 21 falls on the ground, and then the drill rod 7 and the drill 8 are connected and installed on the transmission rod 36. Under the cooperation of the pressure transmission mechanism 3 and the limit mechanism 5, the drill 8 is driven to move downward, and the drive mechanism 4 drives the drill 8 to rotate through the transmission rod 36 to realize the drilling operation. After reaching the sampling position, the drill 8 is reversed, and the guide plate 87 is automatically opened by being blocked by the soil material, so that the soil material enters the sample storage groove 85. During the sampling process, the hydraulic cylinder 2 33 can be used to realize the up and down reciprocating movement of the drill 8 to improve the sampling efficiency. After the sampling is completed, the pressure transmission mechanism 3 is lifted by the winch 12, and the drill rod 7 is removed in turn in cooperation with the clamping plate 6. During the upward movement of the drill 8, it is ensured that the drill 8 rotates in the same rotation direction as the drilling, so that the guide plate 87 remains in a closed state to avoid sample admixture.

[0038] The above describes the utility model and its implementation methods, which are not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and do not deviate from the purpose of the invention of the utility model, they can creatively design a structure and embodiment similar to the technical solution, which should belong to the protection scope of the utility model.
