[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Fig.10 As shown, the existing geological exploration drilling equipment includes a machine platform 39, on which a hydraulic telescopic component 43 is installed, and the telescopic end of the hydraulic telescopic component 43 is connected to a drilling component 42. When drilling a certain area, a plurality of hole positions at different angles are first pre-positioned in the area, and a base is built at each hole position. Then, the drilling equipment is moved to each hole position, and the drilling component 42 is driven by the hydraulic telescopic component 43 to move and drill holes. After each hole position is drilled, the entire drilling equipment is moved and adjusted to the next base, and adjusted according to the hole position angle before drilling.

[0032] like Figure 1-Figure 9As shown, a multi-hole geological exploration drilling equipment includes a support frame 1, and a plurality of ground anchors 2 are connected circumferentially on the support frame 1. The ground anchors 2 are used to fix the support frame 1 on the corresponding flat ground. A support bottom block 5 is arranged at the inner center position of the support frame 1. A plurality of connecting cross plates 3 are connected circumferentially on the support bottom block 5. The support bottom block 5 is fixedly connected to the support frame 1 through the connecting cross plates 3. Each connecting cross plate 3 is provided with a tilting feedback mechanism. The tilting feedback mechanism includes an adjusting screw 24. The adjusting screw 24 passes through the corresponding connecting cross plate 3, and the adjusting screw 24 is threadedly connected to the corresponding connecting cross plate 3. The adjusting screw A connecting slot 28 is provided at the bottom end of the connecting slot 28, a first slide column 32 is vertically slidably inserted in the connecting slot 28, a supporting base 31 is fixedly connected to the bottom end of the first slide column 32, a first spring 30 is connected between the supporting base 31 and the adjusting screw 24, an end of the first slide column 32 away from the supporting base 31 is a bent end, a remote control button switch 29 aligned with the bent end of the first slide column 32 is fixedly connected to the inner wall of the connecting slot 28, a storage power supply 6 is installed at the bottom of the supporting bottom block 5, and a power-on knife 26 electrically connected to the storage power supply 6 is fixedly installed at one end of the supporting bottom block 5, and the model is HS11 F-200, the power switch 26 is connected to the transmission end of the storage power source 6 for controlling the power output. The power switch 26 is provided with a switch arm 25.

The power switch 26 is horizontally fixed with an electric telescopic rod 27 electrically connected to each remote control button switch 29. The telescopic end of the electric telescopic rod 27 is aligned with the switch arm 25. When the support frame 1 is fixed to the ground at the corresponding survey position by the anchor 2, the adjusting screw 24 at each position is rotated so that the adjusting screw 24 drives the corresponding support base 31 to descend and contact the ground. After the support base 31 contacts the ground, the connected first sliding column 32 slides into the connection slot 28. The first spring 30 is compressed during the drilling process. When one end of the support frame 1 is tilted due to the drilling reaction force, the adjusting screw 24 at this position is tilted accordingly, causing the support base 31 at the bottom to leave the ground. In this way, the first slide column 32 connected to the support base 31 is reset under the action of the rebound force of the first spring 30, and then the bent end of the first slide column 32 abuts against the remote control button switch 29. The remote control button switch 29 causes the electric telescopic rod 27 to start extending, and then the telescopic end of the electric telescopic rod 27 abuts against the knife arm 25, causing the knife arm 25 to rotate out from the energized knife 26, causing the circuit of the storage power supply 6 to be disconnected, thereby stopping the entire drilling equipment to avoid the entire equipment from tipping over due to continued operation;

[0033] The supporting bottom block 5 is rotatably connected with a rotating seat 7, and a disc 12 is fixedly connected to the rotating seat 7 through a frame. A first servo motor 14 is fixedly connected to the middle position of the front end surface of the disc 12. The spindle end of the first servo motor 14 is horizontally forward. The spindle end of the first servo motor 14 is fixedly connected to a hydraulic telescopic rod 11. The telescopic end of the hydraulic telescopic rod 11 is fixedly connected to a second servo motor 10 through a connecting frame. The spindle end of the second servo motor 10 is fixedly connected to a drill rod 4. First, the first servo motor 14 is started to adjust the inclination angle of the drill rod 4, and then the second servo motor 10 is started to rotate the drill rod 4. Finally, the hydraulic telescopic rod 11 is started to extend, and the drill rod 4 is rotated and inserted into the ground to achieve drilling. The start-stop mechanism includes a plurality of jacks 16, which are circumferentially arranged at the edge of the front end surface of the disc 12. A power-off button switch 17 is fixedly connected in each jack 16. All the power-off button switches 17 are connected in series in sequence through wires, and the storage power supply 6 and the first servo motor 14 are connected in series to the circuit of the power-off button switch 17 to achieve electrical connection. A second spring 18 is connected between the button end and the fixed end of each power-off button switch 17. A laser sensor switch electrically connected to the second servo motor 10 and the extension control circuit of the hydraulic telescopic rod 11 is also installed on the inner wall of the jack 16. A rubber sealing cover 20 is connected to the port of each jack 16 through soft glue. The side wall of the disc 12 corresponding to the jack 16 A sliding top block 22 is inserted and slidably interspersed on the upper part, and a third spring 21 is connected between the sliding top block 22 and the disc 12. One end of the sliding top block 22 is in the socket 16, and the other end is outside the disc 12. The end of the sliding top block 22 away from the socket 16 is rotatably connected to a movable block 23 through a rebound hinge. The connecting end of the movable block 23 is spliced ​​at the end of the sliding top block 22, and the rebound hinge is connected to one side edge of the connecting end. In this way, it can be ensured that the movable block 23 drives the sliding top block 22 to slide when it is axially squeezed. The telescopic end of the hydraulic telescopic rod 11 is fixedly connected with a strip extrusion plate 15. The movable blocks 23 distributed on the disc 12 are all on the moving track of the strip extrusion plate 15. The fixed end of the hydraulic telescopic rod 11 is also provided with a spring The elastic telescopic member, the sockets 16 distributed on the disc 12 are on the rotation track of the elastic telescopic member; the elastic telescopic member includes a telescopic connecting rod 41, the telescopic connecting rod 41 is horizontally fixedly connected to the fixed end of the hydraulic telescopic rod 11, and is parallel to the strip extrusion plate 15, a fourth spring 40 is connected between the telescopic end and the fixed end of the telescopic connecting rod 41, and a tilted ejector block 19 is fixedly connected to the telescopic end of the telescopic connecting rod 41. Under the drive of the first servo motor 14, the hydraulic telescopic rod 11 drives the tilted ejector block 19 to make a clockwise circular motion, and the tilted ejector block 19 passes through the positions of each socket 16 in turn. When the tilted ejector block 19 contacts the outer surface of the disc 12, the telescopic connecting rod 41 is in a contracted state, and the fourth spring 40 is in a compressed state at this time;

[0034] The first servo motor 14 , the hydraulic telescopic rod 11 and the second servo motor 10 are all electrically connected to the storage power supply 6 , and each circuit passes through the power switch 26 .

[0035] When it is necessary to drill a plurality of holes at different angles, the jacks 16 at the corresponding positions on the disc 12 are selected according to the angle of each hole to be drilled, and the jacks 16 at other angles are closed by the rubber closures 20, and then the first servo motor 14 is started, and the first servo motor 14 drives the drill rod 4 to rotate and adjust the angle through the hydraulic telescopic rod 11, and at the same time, the telescopic connecting rod 41 on the hydraulic telescopic rod 11 rotates accordingly, and the inclined top block 19 at the telescopic end of the telescopic connecting rod 41 slides along the surface of the disc 12, and in this process, the telescopic connecting rod 41 In the contracted state, the fourth spring 40 is in the compressed state. When the inclined ejector block 19 slides to the position of the opening of the socket 16, the inclined ejector block 19 is inserted into the socket 16 under the action of the rebound force of the fourth spring 40, and presses on the power-off button switch 17 in the socket 16. The power-off button switch 17 stops the first servo motor 14, that is, the automatic positioning stop is realized. At this time, the angle of the drill rod 4 is the angle to be drilled, and then the laser sensor switch in the socket 16 generates an induction, starts the hydraulic telescopic rod 11 and the second servo motor 10, so that the drill rod 4 rotates and drills into the ground to realize drilling;

[0036] After the drilling is completed, the hydraulic telescopic rod 11 is controlled to retract, and the strip extrusion plate 15 is squeezed to the corresponding movable block 23 during the driving process of the first servo motor 14. During the extension process of the hydraulic telescopic rod 11, the strip extrusion plate 15 is separated from the corresponding movable block 23, and the movable block 23 is rotated and reset, and then the strip extrusion plate 15 is aligned with the movable block 23. When the hydraulic telescopic rod 11 is retracted, the strip extrusion plate 15 squeezes the movable block 23 along the diameter direction of the disc 12. At this time, the movable block 23 is squeezed and pushes the sliding top block 22 to insert into the corresponding jack 16. The sliding top block 22 is pressed onto the inclined surface of the inclined top block 19, and then the two slide relative to each other during the squeezing process, and the inclined top block 19 is separated from the socket 16 by the contraction of the telescopic connecting rod 41, so that the power-off button switch 17 that was originally pressed is reset under the rebound force of the second spring 18, so that the circuit where the first servo motor 14 is located is powered on again, so that the first servo motor 14 continues to drive the hydraulic telescopic rod 11 and the drill rod 4 to rotate until it encounters the socket 16 at the next position, and then stops again, and then drills, so that multiple holes at different angles are drilled;

[0037] The drill rod 4 is a hollow rod, and a coring mechanism is provided on the drill rod 4. The coring mechanism includes a second slide column 34, which is slidably connected to the inner bottom of the drill rod 4. A rubber slide plug 35 is fixedly sleeved on the second slide column 34, and a fifth spring 44 is connected between the rubber slide plug 35 and the inner wall of the drill rod 4. The bottom end of the second slide column 34 is movably connected to a linkage rod 36 through a hinge. A digging pipe 37 is slidably provided on the inner bottom of the drill rod 4, and one end of the digging pipe 37 penetrates the side wall of the drill rod 4. The other end of the pipe 37 is movably connected to the end of the linkage rod 36 through a hinge. The end of the digging pipe 37 that penetrates the side wall of the drill rod 4 is in an oblique shovel shape, and the digging pipe 37 is a compression-resistant stainless steel alloy body; a pressurizing mechanism is provided between the rotating seat 7 and the drill rod 4, and the pressurizing mechanism includes a water tank 13, the water tank 13 is fixedly connected to the rotating seat 7, a high-pressure water pump 8 is installed on the water tank 13, the storage power supply 6 supplies power to the high-pressure water pump 8, the water pumping end of the high-pressure water pump 8 is connected to the inside of the water tank 13, and the water outlet end A threaded connection pipe head 9 is connected through a hose, and a threaded connection port 33 matching the threaded connection pipe head 9 is connected to the end of the drill rod 4 near the second servo motor 10. When the drill rod 4 is drilled to the corresponding depth position, the threaded connection pipe head 9 is threadedly connected to the threaded connection port 33, and then the high-pressure water pump 8 is started. The high-pressure water pump 8 introduces the water in the water tank 13 into the hollow drill rod 4 at a certain pressure, and the water pressure acts on the rubber slide plug 35. The rubber slide plug 35 drives the second slide column 34 to slide toward the bottom of the drill rod 4, so that the second slide column 34 pushes the digging pipe 37 to slide out of the drill rod 4 through the linkage rod 36. The slid-out digging pipe 37 is inserted into the corresponding geological layer by the inclined shovel end, and then the second servo motor 10 is started to drive the drill rod 4 to rotate a certain angle and then stop, so that the digging pipe 37 digs a certain amount of geological layer samples into its inner side, and then the hydraulic telescopic rod 11 is controlled to contract, so that the drill rod 4 withdraws with the digging pipe 37 to achieve coring;

[0038] A needle rod 38 is fixedly connected to the inner wall of the digging tube 37. There are multiple needle rods 38, which are evenly distributed on the inner wall of the digging tube 37. The needle rods 38 are convenient for clamping the collected geological layer samples to prevent them from falling during the recovery process.

[0039] The working principle of the present invention is as follows: after the support frame 1 is fixed on the ground at the corresponding survey position through the ground anchor 2, the adjusting screw 24 at each position is rotated so that the adjusting screw 24 drives the corresponding support base 31 to descend and contact the ground. After the support base 31 contacts the ground, the connected first sliding column 32 slides and rises into the connecting slot 28, and the first spring 30 is compressed during the process.

[0040] Then, according to the angle of each hole to be drilled, the jack 16 at the corresponding position on the disc 12 is selected to be in an open state, and then the jacks 16 at other angles are closed by the rubber sealing covers 20, and then the first servo motor 14 is started, and the first servo motor 14 drives the drill rod 4 to rotate and adjust the angle through the hydraulic telescopic rod 11, and at the same time, the telescopic connecting rod 41 on the hydraulic telescopic rod 11 rotates accordingly, and the inclined top block 19 at the telescopic end of the telescopic connecting rod 41 slides along the surface of the disc 12, and in this process, the telescopic connecting rod 41 is rotated. The rod 41 is in a contracted state, and the fourth spring 40 is in a compressed state. When the inclined ejector block 19 slides to the position of the opening of the plug hole 16, the inclined ejector block 19 is inserted into the plug hole 16 under the action of the rebound force of the fourth spring 40, and presses on the power-off button switch 17 in the plug hole 16. The power-off button switch 17 stops the first servo motor 14, that is, the automatic positioning stop is realized. At this time, the angle of the drill rod 4 is the angle to be drilled, and then the hydraulic telescopic rod 11 and the second servo motor 10 are started to rotate the drill rod 4 and drill into the ground to realize drilling.

[0041] After the drill rod 4 is drilled to the corresponding depth position, the threaded connection pipe head 9 is threadedly connected to the threaded connection port 33, and then the high-pressure water pump 8 is started. The high-pressure water pump 8 introduces the water in the water tank 13 into the hollow drill rod 4 at a certain pressure, and the water pressure acts on the rubber sliding plug 35. The rubber sliding plug 35 drives the second sliding column 34 to slide toward the bottom of the drill rod 4, so that the second sliding column 34 pushes the digging pipe 37 to slide out of the drill rod 4 through the linkage rod 36. The slid-out digging pipe 37 is inserted into the corresponding geological layer by the inclined shovel end, and then the second servo motor 10 is started to drive the drill rod 4 to rotate a certain angle and then stop, so that the digging pipe 37 digs a certain amount of geological layer samples into its inner side, and then the hydraulic telescopic rod 11 is controlled to shrink, so that the drill rod 4 withdraws with the digging pipe 37 to achieve coring;

[0042] After the drilling is completed, the hydraulic telescopic rod 11 is controlled to retract, and the strip extrusion plate 15 is squeezed to the corresponding movable block 23 during the driving process of the first servo motor 14. During the extension of the hydraulic telescopic rod 11, the strip extrusion plate 15 is separated from the corresponding movable block 23, and the movable block 23 is rotated and reset, and then the strip extrusion plate 15 is aligned with the movable block 23. When the hydraulic telescopic rod 11 is retracted, the strip extrusion plate 15 squeezes the movable block 23 along the diameter direction of the disc 12. At this time, the movable block 23 is squeezed and pushes the sliding top block 22 to insert into the corresponding jack 16. The sliding top block 22 is pressed onto the inclined surface of the inclined top block 19, and then the two slide relative to each other during the squeezing process, and the inclined top block 19 is separated from the socket 16 by the contraction of the telescopic connecting rod 41, so that the power-off button switch 17 originally pressed by the top is reset under the rebound force of the second spring 18, so that the circuit where the first servo motor 14 is located is powered on again, so that the first servo motor 14 continues to drive the hydraulic telescopic rod 11 and the drill rod 4 to rotate until it encounters the socket 16 at the next position, and then stops again, and then drills, so that multiple holes at different angles are drilled;

[0043] At the same time, during the drilling process, when one end of the support frame 1 is tilted up due to the drilling reaction force, the adjusting screw 24 at this position is also tilted up, causing the bottom support base 31 to leave the ground, so that the first slide column 32 connected to the support base 31 is reset under the action of the rebound force of the first spring 30, and then the bent end of the first slide column 32 abuts against the remote control button switch 29, and the remote control button switch 29 causes the electric telescopic rod 27 to start extending, and then the telescopic end of the electric telescopic rod 27 abuts against the knife arm 25, causing the knife arm 25 to rotate out from the energized knife 26, causing the circuit of the storage power supply 6 to be disconnected, thereby shutting down the entire drilling equipment, that is, the first servo motor 14 and the hydraulic telescopic rod 11 are immediately shut down to avoid continuing to run and causing the entire equipment to tip over.

[0044] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
