Abstract
Description
Technical Field
[0001] This application relates to the technical field of mining machinery, and in particular to a geological drilling rig. Background Technology
[0002] In the field of mining machinery and equipment, portable or lightweight geological exploration drilling rigs, widely used in small and medium-sized geological exploration scenarios, fall under the category of mining machinery and equipment. With their advantages of small size, easy mobility, and adaptability to complex terrain, they occupy an important position in urban geological exploration, exploration along highways and railways, and small-scale mine surveys. These drilling rigs are typically driven by hydraulic or mechanical power, using a drill rod to rotate the core drill bit, allowing underground soil or rock strata to enter the core drill pipe and form a complete core sample. After core extraction, the core sample is discharged from the drill pipe, enabling the collection and analysis of geological samples.
[0003] However, in the existing coring process, the core sample removal stage has long relied on manual operation, becoming a major bottleneck restricting the improvement of exploration efficiency. Specifically, after the coring drill pipe has been drilled and brought to the surface, the core sample (especially fine-grained soil core samples such as cohesive soil and silt) is easily adhered to the inner wall of the drill pipe due to adsorption and friction, making it difficult to detach naturally. At this time, the operator needs to manually support the drill pipe to maintain its stability, and then use tools such as hammers and steel chisels to repeatedly strike the end or side wall of the drill pipe. Through vibration, the bonding force between the core sample and the drill pipe is broken, forcing the core sample to be discharged from the drill pipe.
[0004] This manual core removal method has several significant drawbacks: First, the operation is cumbersome, requiring at least 1-2 operators to work together—one to hold the drill pipe in place and the other to perform the tapping operation. The tapping process necessitates constant adjustments to the drill pipe angle and tapping position, increasing operational complexity. Second, the operation efficiency is extremely low. For core samples with high viscosity or long lengths, they often need to be transported to a specific workstation for complete removal, extending the single-hole core extraction cycle and increasing energy consumption. Utility Model Content
[0005] In order to improve the coring efficiency of exploration drilling rigs and reduce energy consumption during the coring process, this application provides a geological drilling rig.
[0006] The geological drilling rig provided in this application adopts the following technical solution: A geological drilling rig includes a rig body, an assembly plate mounted on the rig body, a mounting base on the assembly plate, a fixing component for fixing a drill pipe on the mounting base, a vibration component for connecting the mounting base and the assembly plate, a spray component for spraying water into the drill pipe mounted on the mounting base, a placement platform on one side of the assembly plate, a plurality of placement boxes for placing core samples on the placement platform, a connecting plate between the placement platform and the assembly plate, the placement platform being positioned directly below the connecting plate, the connecting plate including a main plate, a rotating plate and a drive motor, the rotating plate being rotatably connected to the main plate, and the drive motor being mounted on the main plate and fixedly connected to the rotating plate.
[0007] By adopting the above technical solution, the drill pipe can be placed on the mounting base on the assembly plate. Water is then added to the drill pipe through the spray assembly, and the drill pipe is vibrated by the vibration assembly. The core material inside the drill pipe can then fall onto the connecting plate. Subsequently, by controlling the drive motor, the drive motor drives the rotating plate to rotate, causing the core material to fall into the placement box on the placement platform. This allows for a rapid completion of the core extraction process, improving the core extraction efficiency of the exploration drilling rig and reducing the energy consumption required to transport difficult-to-remove core material from the drill pipe to the core extraction equipment in the plant area, thus saving energy.
[0008] Optionally, the fixing assembly includes a fixing plate rotatably connected to the mounting base, a fixing bolt threadedly connected to the fixing plate, and the shank of the fixing bolt threadedly connected to the mounting base.
[0009] By adopting the above technical solution, the fixing component uses a fixing plate that is rotatably connected to the mounting base and fixing bolts that are threadedly connected to the fixing plate and the mounting base, which can securely fix the drill pipe to the mounting base.
[0010] Optionally, the vibration assembly includes a connecting column fixedly connected to the upper end of the assembly plate, a support plate ball-hinged to the upper end of the connecting column, a mounting base fixedly connected to the support plate, a plurality of springs fixedly connected between the assembly plate and the support plate, and a vibration motor mounted on the support plate.
[0011] By adopting the above technical solution, the vibration motor can be started, and the support plate can be vibrated by the vibration motor, thereby vibrating the drill pipe.
[0012] Optionally, a sieve plate is fixedly connected to the side of the placement box away from the assembly plate, and a collection hopper is provided below the sieve plate.
[0013] By adopting the above technical solution, the water accumulated on the connecting plate can be drained through the sieve plate, reducing the impact of water accumulation on core material collection.
[0014] Optionally, two adjacent placement boxes are fixedly connected. The output shaft end of the drive motor is located outside the main board, and both ends of the drive motor output shaft are fixedly connected to a lever. A support rod is fixedly connected to the outer wall of the placement box. A vertical rod is fixedly connected to the placement platform. The vertical rod corresponds one-to-one with the lever. A connecting shaft is rotatably connected to the vertical rod. A force-bearing rod is fixedly connected to the connecting shaft. The force-bearing rod abuts against the lever. A drive rod is fixedly connected to the connecting shaft. An abutting rod is hinged to the drive rod. The abutting rod abuts against the support rod. The abutting rod can only rotate towards the side closer to the connecting plate.
[0015] By adopting the above technical solution, when the drive motor rotates, it will simultaneously drive the actuating rod to rotate, which in turn drives the force rod to rotate. This force rod, through the connecting shaft, drives the drive rod to rotate, causing the abutting rod to abut against the support rod, thereby moving the placement box. Thus, when the core material enters the placement box, the corresponding placement box can automatically enter the placement box, thereby automatically moving the placement box and collecting the core material in sequence.
[0016] Optionally, a torsion spring is sleeved on the connecting shaft, one end of the torsion spring is fixedly connected to the upright, and the other end of the torsion spring is fixedly connected to the drive rod.
[0017] By adopting the above technical solution, the torsion spring can quickly reset the abutment rod and the drive rod, thereby enabling the abutment rod and the drive rod to continuously move the placement box.
[0018] Optionally, the spray assembly includes a spray pipe mounted on the assembly plate, the spray pipe being located on the side of the assembly plate away from the placement platform, and the spray pipe having multiple nozzles mounted on it.
[0019] By adopting the above technical solution, spraying can be carried out into the drill pipe through the spray pipe and nozzle, which facilitates the core material to be separated from the drill pipe.
[0020] Optionally, a rotating shaft is rotatably connected to the drilling rig body, a lifting rod is fixedly connected to the rotating shaft, and a rotating motor for driving the rotating shaft to move is installed on the drilling rig body.
[0021] By adopting the above technical solution, the lifting rod can be moved by rotating the motor, thereby moving the drill pipe out of the assembly plate.
[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotating plate is driven by a drive motor to rotate, so that the core material falls into the placement box on the placement platform. This can quickly complete the core retrieval process of the drill pipe, improve the core retrieval efficiency of the exploration drilling rig, reduce the energy consumption in the process of transferring the core material that is difficult to remove from the drill pipe to the core retrieval equipment in the plant area, and save energy. 2. The drill pipe can be vibrated by starting the vibration motor, which drives the support plate to vibrate. 3. The force-bearing rod can drive the drive rod to rotate through the connecting shaft, thereby causing the abutment rod to abut against the support rod, which in turn drives the placement box to move. Thus, when the core material enters the placement box, the corresponding placement box can automatically enter the placement box, thereby automatically realizing the movement of the placement box and thus collecting the core material in sequence.

[0025] The following is in conjunction with the appendix Figure 1 - Appendix Figure 3 This application will be described in further detail below.
[0026] An embodiment of this application is: a geological drilling rig, referring to... Figure 1 The system includes a geological drilling rig body 1, which is a geological exploration drilling rig as described in the prior art. An assembly plate 2 is mounted on the drilling rig body 1, and the assembly plate 2 is rectangular in shape. Two mounting seats 3 are provided on the assembly plate 2, located at opposite ends of the assembly plate 2. Each mounting seat 3 is equipped with a fixing component 4 for securing the drill pipe to the mounting seat 3.
[0027] Reference Figure 1 and Figure 2 The fixing component 4 includes a fixing plate 41 rotatably connected to the mounting base 3. A fixing bolt 42 is threaded onto the fixing plate 41. The shank of the fixing bolt 42 is threaded onto the mounting base 3, thereby the drill pipe can be securely fixed onto the mounting base 3 by means of the fixing bolt 42.
[0028] A vibration assembly 5 is provided between the mounting base 3 and the assembly plate 2 to connect the two. The vibration assembly 5 includes two connecting columns 51 fixedly connected to the upper end of the assembly plate 2. A support plate 52 is ball-hinged to the upper end of the connecting column 51. The support plate 52 is set parallel to the assembly plate 2. The mounting base 3 is fixedly connected to the support plate 52. Multiple springs 53 are fixedly connected between the assembly plate 2 and the support plate 52. In this embodiment, four springs 53 are used. A vibration motor 54 is mounted on the support plate 52.
[0029] A spray assembly 6 for spraying water into the drill pipe is installed on the mounting base 3. The spray assembly 6 includes a spray pipe 61 mounted on the mounting plate 2, and the spray pipe 61 is annular. The spray pipe 61 is located on the side of the mounting plate 2 away from the placement platform 7. Multiple nozzles 62 are installed on the spray pipe 61, and the multiple nozzles 62 are equidistantly arranged along the circumference of the spray pipe 61. Thus, water can be sprayed into the drill pipe through the spray pipe 61 and the nozzles 62, facilitating the separation of the core material from the drill pipe. At the same time, in order to facilitate the collection of sprayed water, a screen plate 10 is fixedly connected to the side of the placement box 8 away from the mounting plate 2. The end of the mounting plate 2 near the screen plate 10 is inclined downward. A collection hopper 11 is provided below the screen plate 10, and the collection hopper 11 is mounted on the drilling rig body 1.
[0030] Reference Figure 1 and Figure 3 A rotating shaft 12 is rotatably connected to the drilling rig body, and a lifting rod 13 is fixedly connected to the rotating shaft 12. A rotating motor 14 is installed on the drilling rig body to drive the rotating shaft 12 to move. The rotating motor 14 can then drive the lifting rod 13 to move, thereby moving the drill pipe outside the assembly plate 2.
[0031] A placement platform 7 is provided on one side of the assembly plate 2. Multiple placement boxes 8 for placing core samples are provided on the placement platform 7. The placement boxes 8 are slidably connected to the placement platform 7. A connecting plate 9 is provided between the placement platform 7 and the assembly plate 2. The placement platform 7 is located directly below the connecting plate 9. The connecting plate 9 includes a main plate 91, a rotating plate 92 and a drive motor 93. The rotating plate 92 is rotatably connected to the main plate 91. The drive motor 93 is mounted on the main plate 91 and fixedly connected to the rotating plate 92.
[0032] After the core material detaches from the drill pipe, it can fall onto the connecting plate 9. Then, by controlling the drive motor 93, the rotating plate 92 is rotated, causing the core material to fall into the placement box 8 on the placement platform 7.
[0033] Two adjacent placement boxes 8 are fixedly connected. The output shaft end of the drive motor 93 is located outside the main board 91, and both ends of the output shaft of the drive motor 93 are fixedly connected to a lever 15. A support rod 16 is fixedly connected to the outer wall of the placement box 8. A vertical rod 22 is fixedly connected to the placement platform 7. The vertical rod 22 corresponds one-to-one with the lever 15. A connecting shaft 17 is rotatably connected to the vertical rod 22. A force-bearing rod 18 is fixedly connected to the connecting shaft 17. The force-bearing rod 18 abuts against the lever 15. A drive rod 19 is fixedly connected to the connecting shaft 17. The length of the drive rod 19 is longer than that of the force-bearing rod 18. An abutting rod 20 is hinged to the drive rod 19. The abutting rod 20 abuts against the support rod 16. A torsion spring 21 is sleeved on the connecting shaft 17. One end of the torsion spring 21 is fixedly connected to the vertical rod 22, and the other end of the torsion spring 21 is fixedly connected to the drive rod 19. The abutting rod 20 can only rotate towards the side closer to the connecting plate 9.
[0034] Therefore, when the drive motor 93 rotates, it will simultaneously drive the actuating rod 15 to rotate, which in turn drives the force rod 18 to rotate. This causes the force rod 18 to drive the drive rod 19 to rotate via the connecting shaft 17, which in turn causes the abutting rod 20 to abut against the support rod 16, thereby moving the placement box 8. Thus, when the core material enters the placement box 8, the corresponding placement box 8 can automatically enter the placement box 8, thereby automatically realizing the movement of the placement box 8.
[0035] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be included within the scope of protection of this application.
