Description

Technical Field

[0001] This invention relates to the field of drilling technology, and in particular to a drilling rig for rock geology exploration and its method of use. Background Technology

[0002] A drilling rig is a complex machine consisting of components, units, and mechanisms. In exploration or mineral resource development, a drilling rig is a mechanical device that drives a drilling tool to drill underground to obtain physical geological data. Also known as a drilling machine, its main function is to drive the drilling tool to break the rock at the bottom of the hole and lower or lower the drilling tool into the hole. It can be used to drill for core samples, mineral core samples, rock cuttings, gaseous samples, liquid samples, etc., to explore underground geology and mineral resources.

[0003] Due to the different geological conditions of the rocks, the drill bit will generate varying degrees of heat during operation due to friction. Failure to cool it down in time will greatly affect the service life of the drill bit. Furthermore, as the drill rod rotates, it will continuously carry out geological soil from different depths. Since the geological conditions vary at different depths of the rock, existing drilling rigs are unable to classify, collect, and test the geological soil from different depths. Summary of the Invention

[0004] In view of the above situation and to overcome the shortcomings of the prior art, the present invention provides a drilling rig for exploration based on rock geology and its usage method, which effectively solves the problems in the prior art of not being able to reasonably cool the drill bit according to the geology and not being able to classify, collect and test geological soil at different depths.

[0007] Furthermore, the adjustable cooling structure includes a second motor fixedly connected to the drill rod. A large gear is located at the lower end of the drill rod, meshing with a small gear. A rotating rod is fixedly connected to the small gear. A large annular grooved wheel and a small annular grooved wheel are fitted onto the rotating rod. A shaft is rotatably connected to the rotating rod at the groove of the large annular grooved wheel. A connecting rod is rotatably connected to the upper end of the large annular grooved wheel, and the other end of the connecting rod is rotatably connected to the lower end of the small annular grooved wheel. A support wheel is located in the inner groove of the small annular grooved wheel, and a first screw is fixedly connected to the support wheel. The mounting plate has a first support block at one end that is rotatably connected to the rotating rod. The first support block is threadedly connected to the first screw. A ball rod is provided in the inner groove of the large annular groove wheel. A pressure rod is fixedly connected to one end of the ball rod. A negative pressure tank corresponding to the pressure rod is provided on the mounting plate. An inlet check valve and an outlet check valve are respectively provided on the negative pressure tank. The outlet check valve is connected to the outlet pipe. A water tank is provided at the other end of the mounting plate. An inlet pipe connected to the inlet check valve is provided in the water tank.

[0008] Furthermore, the sorting and collecting structure includes a cam and a grooved wheel fixedly connected to the first transmission rod. A sliding pin is provided in the inner groove wall of the cam, and a sliding column is fixedly connected to the sliding pin. A central connecting plate is provided at one end of the sliding column. A pin is provided in the inner groove wall of the grooved wheel, and a rotating shaft is fixedly connected to the pin. A sliding cylinder is fixedly connected to the rotating shaft. A sliding rod is provided inside the sliding cylinder and fixedly connected to the other end of the central connecting plate. A base is provided at the lower end of the support plate, and a second support block is provided at one end of the base. The inner wall of the second support block is slidably connected to the sliding column and the sliding cylinder, respectively. A flipping rod is provided at one end of the sliding rod. A push rod is fixedly connected, and a rectangular block is also set between the bases.

[0009] Furthermore, the support plate has through holes corresponding to the drill rod, and the push rod is located on the side where the lower end of the through hole contacts the ground.

[0010] A method for using an exploration drilling rig based on rock geology, comprising: S1. The pressure-applying structure applies downward pressure to the drill rod and drill bit, and in conjunction with the rotation of the drill rod and drill bit, drills into the rock geology; S2. The geological conditions at different depths are different, and the heat generated by the drill bit due to friction is also different. In order to cool the drill bit in a targeted manner, the adjustable cooling structure works. The liquid outlet pipe sprays water onto the drill rod in a metered manner. The water flows down the drill rod to cool the drill bit and drill rod, thereby improving the service life of both. S3. When the drill bit drills into the geology, because the drill rod is threaded, it can bring out geological soil at different depths. The sorting and collection structure works to sort the geological soil at different depths and transport it into the collection box for easy testing of geological soil at different depths.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention features an adjustable cooling structure. Different geological conditions at different depths and varying heat generated by the drill bit due to friction allow for targeted cooling of the drill bit and drill rod. The adjustable cooling structure dispenses water in a measured amount from the outlet pipe onto the drill rod, allowing the water to flow down the drill rod and cool both the drill bit and drill rod, thus extending their service life.

[0012] 2. By setting up a classification and collection structure, when the drill bit drills into the geological soil, the drill rod is threaded, so geological soil at different depths can be continuously brought out. The pusher plate is used to classify and transport the geological soil at different depths to different chambers in the collection box, which facilitates the testing of geological soil at different depths.

[0014] A drilling rig for exploration based on rock geology, such as Figure 1-13 As shown, the system includes a support plate 1, with support rods 5 at both ends of the support plate 1. A cover plate 3 is provided at the upper end of the support rods 5. A pressure-applying structure is provided on the support plate 1, and the pressure-applying structure is poweredly connected to an mounting plate 9. A drilling rig is provided on the mounting plate 9, and the drilling rig includes a drill rod 7. A drill bit 8 is provided at the lower end of the drill rod 7. An adjustable cooling structure that works with the drilling rig is also provided on the mounting plate 9. The adjustable cooling structure includes a liquid outlet pipe 24 corresponding to the drill rod 7. A classification and collection structure that works with the drilling rig is provided at the lower end of the support plate 1. The classification and collection structure includes a collection box 50 that can classify and collect geological samples at different depths.

[0015] In use, the pressure-applying structure applies downward pressure to the drill rod 7 and drill bit 8. Combined with the rotation of the drill rod 7 and drill bit 8, this allows for drilling into the rock. Different depths of geological conditions result in different heat generation from friction in the drill bit 8. To specifically cool the drill bit 8, an adjustable cooling structure operates. The outlet pipe 24 sprays a measured amount of water onto the drill rod 7. The water flows down the drill rod 7, cooling both the drill bit 8 and the drill rod 7 and improving their service life. When the drill bit 8 drills into the geology, the threaded shape of the drill rod 7 allows for the removal of soil samples from different depths. A sorting and collection structure then sorts and transports the soil samples from different depths into the collection box 50 for easy testing.

[0016] like Figure 2 and 8 As shown, the pressure-applying structure includes a first motor 30 connected to the support plate 1. The output end of the first motor 30 is fixedly connected to a first transmission rod 33. The first transmission rod 33 is fixedly connected to a driving bevel gear 31. The driving bevel gear 31 meshes with a driven bevel gear 32. The driven bevel gear 32 is fixedly connected to a second screw 34 rotatably connected to the support plate 1. One end of the mounting plate 9 is provided with a connecting plate 36. The inner wall of the connecting plate 36 is provided with a screw cylinder 35 threadedly connected to the second screw 34. Both ends of the mounting plate 9 are respectively provided with limiting cylinders 10 slidably connected to the support rod 5.

[0017] Preferably, the first motor 30 operates, and the output end of the first motor 30 drives the first transmission rod 33 to rotate. During the rotation of the first transmission rod 33, the active bevel gear 31 rotates, the active bevel gear 31 drives the driven bevel gear 32 to rotate, and the driven bevel gear 32 drives the second screw 34 to rotate. The second screw 34 is threadedly engaged with the screw cylinder 35 in the connecting plate 36. Under the limitation of the support rod 5 and the limiting cylinder 10, the mounting plate 9 moves up and down, thereby driving the drill rod 7 and the drill bit 8 to move downward to drill holes in the geology.

[0018] like Figure 3-7As shown, the adjustable cooling structure includes a second motor 6 fixedly connected to the drill rod 7. A large gear 12 is provided at the lower end of the drill rod 7, and a small gear 13 meshes with the large gear 12. A rotating rod 14 is fixedly connected to the small gear 13. A large annular grooved wheel 15 and a small annular grooved wheel 20 are sleeved on the rotating rod 14. A shaft 22 rotatably connected to the rotating rod 14 is provided in the groove of the large annular grooved wheel 15. A connecting rod 21 is rotatably connected to the upper end of the large annular grooved wheel 15, and the other end of the connecting rod 21 is rotatably connected to the lower end of the small annular grooved wheel 20. A support wheel 19 is provided in the inner groove of the small annular grooved wheel 20, and a first screw 16 is fixedly connected to the support wheel 19. One end of the mounting plate 9 is provided with a first support block 18 that is rotatably connected to the rotating rod 14. The first support block 18 is threadedly connected to the first screw 16. The inner groove of the large ring groove wheel 15 is provided with a ball rod 23. One end of the ball rod 23 is fixedly connected to a downward pressure rod 26. The mounting plate 9 is provided with a negative pressure tank 60 corresponding to the downward pressure rod 26. The negative pressure tank 60 is provided with an inlet check valve 28 and an outlet check valve 25. The outlet check valve 25 is connected to the outlet pipe 24. The other end of the mounting plate 9 is provided with a water tank 11. The water tank 11 is provided with an inlet pipe 27 connected to the inlet check valve 28.

[0019] Preferably, when the second motor 6 operates, the output end of the second motor 6 drives the drill rod 7 to rotate. During this process, the large gear 12 rotates, which in turn drives the small gear 13 to rotate. The small gear 13 then drives the rotating rod 14 to rotate. The upper end of the rotating rod 14 is provided with a spline, so the small annular grooved wheel 20 can not only move up and down along the axial direction of the rotating rod 14, but also rotate with the rotating rod 14. A connecting rod 21 is provided between the large annular grooved wheel 15 and the small annular grooved wheel 20 to ensure that the large annular grooved wheel 15 and the small annular grooved wheel 20 can rotate synchronously. When it is necessary to adjust the water flow rate, the upper end of the first screw 16 is provided with a handle 17. The first screw 16 is driven to rotate through the handle 17. The first screw 16 moves up and down through the threaded engagement of the inner wall of the first support block 18. When the first screw 16 moves to the left and right, it rotates up and down. When moving downwards, the first screw 16 presses down on the small annular grooved wheel 20 via the support wheel 19, moving it downwards along the axis of the rotating rod 14. The small annular grooved wheel 20 drives the large annular grooved wheel 15 to rotate around the shaft 22 via the connecting rod 21. Therefore, during the rotation of the large annular grooved wheel 15, the ball rod 23 moves up and down, and the height of the undulation is related to the rotation angle of the large annular grooved wheel 15. During the up and down movement of the ball rod 23, the lower pressure rod 26 moves up and down. The lower pressure rod 26 drives the lower pressure plate 29 to move up and down inside the negative pressure tank 60, generating negative pressure inside the negative pressure tank 60. Water in the water tank 11 enters the negative pressure tank 60 through the inlet pipe 27 and the inlet check valve 28, and is sprayed out through the outlet pipe 24 via the outlet check valve 25 to cool the drill rod 7. The water output can be adjusted reasonably according to different geological conditions.

[0020] like Figure 9-13As shown, the sorting and collecting structure includes a cam 37 and a grooved wheel 38 fixedly connected to the first transmission rod 33. A sliding pin 39 is provided in the inner groove wall of the cam 37, and a sliding column 40 is fixedly connected to the sliding pin 39. A central connecting plate 46 is provided at one end of the sliding column 40. A pin 48 is provided in the inner groove wall of the grooved wheel 38, and a rotating shaft 47 is fixedly connected to the pin 48. A sliding cylinder 43 is fixedly connected to the rotating shaft 47. A sliding rod 42, fixedly connected to the other end of the central connecting plate 46, is provided inside the sliding cylinder 43. A base 2 is provided at the lower end of the support plate 1, and a second support block 41 is provided at one end of the base 2. The inner wall of the second support block 41 is slidably connected to the sliding column 40 and the sliding cylinder 43 respectively. A flipping rod 44 is provided at one end of the sliding rod 42. A pusher plate 45 is fixedly connected to the end of the storage box 50. A rectangular block 59 is also provided between the bases 2. A limiting block 49 that is slidably connected to the rectangular block 59 is provided at one end of the storage box 50. A rack 51 is provided at the upper end of the storage box 50. The rack 51 meshes with an external gear 55. Several evenly arranged limiting grooves are opened on the inner side of the external gear 55. A first spur gear 52 is provided on the slide cylinder 43. The first spur gear 52 meshes with a second spur gear 53. The second spur gear 53 is fixedly connected to a second transmission rod 54 that is rotatably connected to the second support block 41. A ratchet 58 is provided at one end of the second transmission rod 54. A pawl 56 corresponding to the limiting groove is provided on the ratchet 58. An elastic piece 57 corresponding to the pawl 56 is also provided on the ratchet 58.

[0021] Preferably, during the rotation of the first transmission rod 33, the cam 37 and the grooved wheel 38 are simultaneously driven to rotate. During the rotation of the cam 37, it engages with the sliding pin 39, which in turn drives the sliding column 40 to reciprocate along the axial direction of the cam 37. The second support block 41 limits the movement of the sliding column 40. During the reciprocating movement of the sliding column 40, the sliding rod 42 reciprocates along the inner wall of the sliding cylinder 43 via the central connecting plate 46. During the rotation of the grooved wheel 38, the sliding cylinder 43 reciprocates by rotating in both directions via the pin 48 and the rotating shaft 47. Since the sliding rod 42 has a spline corresponding to the sliding cylinder 43, the rotation of the sliding cylinder 43 can drive the sliding rod 42 to rotate by the same angle. After the sliding rod 42 pushes the geological soil into the storage box 50 via the pusher plate 45 through the flipping rod 44, the sliding rod 42 flips the pusher plate 45 by a certain angle and then resets, thus avoiding… The back-pushing of geological soil leads to unclear classification of geological soil at different depths. During the rotation of the slide cylinder 43, the first spur gear 52 rotates, which in turn drives the second spur gear 53. The second spur gear 53 drives the ratchet 58 and pawl 56 to rotate via the second transmission rod 54. During the counterclockwise rotation of the pawl 56, it meshes with the limiting groove on the external gear 55, thereby driving the external gear 55 to rotate. During the clockwise rotation of the pawl 56, it slips off the limiting groove on the external gear 55, causing the external gear 55 to stop rotating. The elastic plate 57 pushes the pawl 56 back. During the rotation of the external gear 55, it meshes with the rack 51, thereby driving the storage box 50 to move a certain distance along the rectangular block 59 under the limitation of the limiting block 49. This allows for switching between different chambers on the storage box 50, facilitating the collection of geological soil at different depths for testing.

[0022] like Figure 1 As shown, the support plate 1 has a through hole 4 corresponding to the drill rod 7, and the pusher plate 45 is located on the side where the lower end of the through hole 4 contacts the ground.

[0023] Preferably, the drill rod 7 and drill bit 8 move down through the through hole 4 to drill the geology, and the soil brought out by the drill rod 7 rests on the circumference of the drill hole, and the push plate 45 can push out the soil on the side of the drill hole.

[0024] The working process of this invention is as follows: When this invention is in use, the first motor 30 works, and the output end of the first motor 30 drives the first transmission rod 33 to rotate. During the rotation of the first transmission rod 33, the active bevel gear 31 rotates, the active bevel gear 31 drives the driven bevel gear 32 to rotate, and the driven bevel gear 32 drives the second screw 34 to rotate. The second screw 34 is threadedly engaged with the screw cylinder 35 in the connecting plate 36. Under the limitation of the support rod 5 and the limiting cylinder 10, the mounting plate 9 moves up and down, thereby driving the drill rod 7 and the drill bit 8 to move downward to drill holes in the geology.

[0025] Different geological conditions at different depths result in different amounts of heat generated by friction in drill bit 8. To specifically cool drill bit 8, second motor 6 operates. The output of second motor 6 drives drill rod 7 and drill bit 8 to drill simultaneously. Drill rod 7 drives large gear 12 to rotate, large gear 12 drives small gear 13 to rotate, and small gear 13 drives rotating rod 14 to rotate. Rotating rod 14 has a spline at its upper end, allowing small annular grooved wheel 20 to move up and down along the axial direction of rotating rod 14 and rotate with it. A connecting rod 21 between large annular grooved wheel 15 and small annular grooved wheel 20 ensures their synchronous rotation. When water flow needs adjustment, a handle 17 is provided at the upper end of first screw 16. The handle 17 drives first screw 16 to rotate. First screw 16 moves up and down through threaded engagement with the inner wall of first support block 18. When the first screw 16 moves downward, it presses the small annular grooved wheel 20 downward along the axis of the rotating rod 14 via the support wheel 19. The small annular grooved wheel 20 drives the large annular grooved wheel 15 to rotate around the shaft 22 via the connecting rod 21. Therefore, during the rotation of the large annular grooved wheel 15, it drives the ball rod 23 to move up and down, and the height of the undulation is related to the rotation angle of the large annular grooved wheel 15. During the up and down movement of the ball rod 23, it drives the pressing rod 26 to move up and down. The pressure plate 29 moves up and down inside the negative pressure tank 60, creating negative pressure inside the tank. Water from the water tank 11 enters the negative pressure tank 60 through the inlet pipe 27 and the inlet check valve 28, and is sprayed out through the outlet check valve 25 and the outlet pipe 24 to cool the drill rod 7. The water output can be adjusted according to different geological conditions. The outlet pipe 24 sprays water onto the drill rod 7 in a measured amount. The water flows down the drill rod 7 to cool the drill bit 8 and the drill rod 7, improving their service life.

[0026] When drill bit 8 drills into the geology, the threaded drill rod 7 can bring out soil at different depths. During the rotation of the first transmission rod 33, the cam 37 and the grooved wheel 38 rotate simultaneously. The cam 37, through the engagement of the sliding pin 39, drives the sliding column 40 to reciprocate along the axial direction of the cam 37. The second support block 41 limits the movement of the sliding column 40. During the reciprocating movement of the sliding column 40, the connecting plate 46 drives the sliding rod 42 to reciprocate along the inner wall of the sliding cylinder 43. During the rotation of the grooved wheel 38, the pin 48 drives the sliding cylinder 43 to rotate forward and backward by a certain angle. Since the sliding rod 42 has a spline corresponding to the sliding cylinder 43, the rotation of the sliding cylinder 43 can drive the sliding rod 42 to rotate by the same angle. After the sliding rod 42 pushes the soil into the storage box 50 through the pusher plate 45 via the flipping rod 44, the sliding rod 42, through the flipping rod 44, flips the pusher plate 45 by a certain angle and then resets, preventing the soil from being pushed back. The classification of geological soil at different depths is unclear. During the rotation of the slide cylinder 43, the first spur gear 52 rotates, which in turn drives the second spur gear 53. The second spur gear 53 drives the ratchet 58 and pawl 56 through the second transmission rod 54. During the counterclockwise rotation of the pawl 56, it meshes with the limiting groove on the external gear 55, thereby driving the external gear 55 to rotate. During the clockwise rotation of the pawl 56, it slips off the limiting groove on the external gear 55, causing the external gear 55 to stop rotating. The elastic plate 57 pushes the pawl 56 back. During the rotation of the external gear 55, it meshes with the rack 51, thereby driving the collection box 50 to move a certain distance along the rectangular block 59 under the limitation of the limiting block 49. This allows for switching between different chambers on the collection box 50, facilitating the collection of geological soil at different depths for testing. Furthermore, during the cooling of the drill bit with water, the geological soil brought out by the drill rod clumps together under the action of water, making it easier to collect.

[0027] This invention also provides a method for using a drilling rig for rock geology exploration, specifically including: S1. The second screw 34 engages with the screw cylinder 35 inside the connecting plate 36. Under the limitation of the support rod 5 and the limiting cylinder 10, the mounting plate 9 moves downward, applying downward pressure to the drill rod 7 and the drill bit 8. In conjunction with the rotation of the drill rod 7 and the drill bit 8, the drilling is performed on the rock geology. S2. The geological conditions at different depths are different, and the heat generated by the drill bit 8 due to friction is also different. In order to cool the drill bit 8 in a targeted manner, the first screw 16 presses down the small annular groove wheel 20 through the support wheel 19 and moves it downward along the axis of the rotating rod 14. The small annular groove wheel 20 drives the large annular groove wheel 15 to rotate around the shaft 22 by a certain angle through the connecting rod 21. Therefore, the large annular groove wheel 15 drives the ball rod 23 to move up and down during the rotation process, and the height of the undulation is related to the rotation angle of the large annular groove wheel 15. This adjusts the water output of the liquid outlet pipe 24. The liquid outlet pipe 24 sprays water onto the drill rod 7, and the water flows down the drill rod 7 to cool the drill bit 8 and the drill rod 7, thereby improving their service life. S3. When the drill bit 8 drills into the geology, since the drill rod 7 is threaded, it can bring out geological soil at different depths. By using the reciprocating movement of the pusher plate 45 and the corresponding change of the chamber in the storage box 50, the geological soil at different depths is classified and transported to different chambers in the storage box 50, which facilitates the testing of geological soil at different depths.

[0028] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
