[0025] Please see Figures 1-4 This utility model provides a technical solution:

[0026] A multifunctional mining drilling device includes two symmetrically arranged support legs 1 and a gantry frame 3. A movable plate 33 that can move up and down is located below the gantry frame 3. Two hydraulic cylinders 34 are symmetrically fixedly connected to the bottom of the gantry frame 3, and the piston rods of both hydraulic cylinders 34 are fixedly connected to the top of the movable plate 33. The gantry frame 3 is rotatably mounted between the two support legs 1. A drill rod 4 is rotatably mounted on the bottom of the movable plate 33. A drill bit 45 that can move up and down is coaxially mounted on the bottom of the drill rod 4. The drill rod 4 is hollow, and several [unclear - possibly referring to components or parts] are installed inside the drill rod 4 above the drill bit 45. The sampling assembly includes a threaded sleeve 46 coaxially welded to the top of the drill bit 45. A threaded rod 43 is installed on the internal thread of the threaded sleeve 46. The threaded rod 43 is rotatably connected to the drill rod 4 via a bearing. The sampling assembly includes a disc 48 fixed near the bottom of the threaded sleeve 46. Several vertical plates 480 are fixedly installed on the disc 48. Each vertical plate 480 is equipped with an L-shaped plate 49 that can move outward. A scraper 47 is installed on the L-shaped plate 49. A drilling motor 31 with an output shaft coaxially fixed to the drill rod 4 is fixedly installed on the top of the movable plate 33. The symmetrically arranged outriggers 1 and gantry 3 form a stable support. The movable plate 33 below the gantry 3 is driven up and down by the hydraulic cylinder 34, achieving precise control of the drill rod 4 and drill bit 45. The drill rod 4 is hollow and integrates a sampling component, enabling simultaneous sampling during drilling and improving work efficiency. The threaded sleeve 46 and threaded rod 43 at the top of the drill bit 45, combined with the bearing rotation connection, allow the drill bit 45 to maintain stable rotation and precisely control the depth. The L-shaped plate 49 and scraper 47 in the sampling component are flexibly designed to adapt to boreholes of different diameters. The drilling motor 31 at the top of the movable plate 33 provides stable power for drilling, realizing automation of the drilling process. In summary, this multi-functional mining drilling device exhibits significant advantages in structural stability, drilling efficiency, sampling accuracy, drill bit 45 control, and power integration.

[0027] It should be added that each support leg 1 has a cross base 2 welded to its bottom, and each cross base has four fixing holes 20. Two limiting blocks 460 are symmetrically welded to the outer circumference of the threaded sleeve 46 near the top. The limiting blocks 460 are slidably connected to the inner wall of the drill rod 4.

[0028] As a preferred embodiment, both the drill rod 4 and the drill bit 45 are provided with spiral-shaped guide grooves 40 on their outer annular walls. The spiral-shaped guide grooves 40 on the outer annular walls of the drill rod 4 and the drill bit 45 help to smoothly discharge the debris and sampling materials generated during drilling, improving drilling efficiency and sampling quality, while reducing the risk of blockage inside the drill rod 4.

[0029] In a preferred embodiment, a horizontal plate 41 is provided above the borehole, and two connecting rods 42 are symmetrically provided at the bottom of the horizontal plate 41. The bottom of the connecting rods 42 is fixedly connected to the top of the drill rod 4. The horizontal plate 41 above the borehole is fixedly connected to the top of the drill rod 4 through the connecting rods 42, which enhances the stability of the drill rod 4, reduces shaking during drilling, improves drilling accuracy and safety, and provides space for the drive head 44 to be turned.

[0030] In a preferred embodiment, the threaded rod 43 extends from the top of the drill rod 4, and a drive head 44 is integrally formed coaxially on its top. The drive head 44 is screw-head shaped and has a standard screw head size. This facilitates the connection of external tools or equipment to the threaded rod 43. By rotating the threaded rod 43, the threaded sleeve is driven to move downward, causing the drill bit 45 to disengage from the drill rod 4. This makes it easier to extend the sampling component from between the drill bit 45 and the drill rod 4, improving the versatility and convenience of the device.

[0031] In a preferred embodiment, both sides of the gantry 3 are rotatably connected to the support legs 1 via connecting shafts 30. The connecting shafts 30 are fixed to the gantry 3, and the connecting shafts 30 are rotatably connected to the support legs 1 via bearings. This allows the angles of the gantry 3 and the drill rod 4 to be flexibly adjusted, adapting to more complex drilling scenarios and improving the adaptability and flexibility of the device.

[0032] In a preferred embodiment, an adjusting motor 32 is installed on one of the outriggers 1, and the output shaft of the adjusting motor 32 is coaxially fixed with the connecting shaft 30. By fixing the output shaft and the connecting shaft 30 coaxially, the electric adjustment of the angles of the gantry 3 and the drill rod 4 is realized, improving the automation level and ease of operation of the drilling device.

[0033] In a preferred embodiment, two guide rods 482 are symmetrically fixedly connected to the vertical plate 480. The guide rods 482 are plugged into the L-shaped plate 49. A drive rod 481, threadedly connected to the L-shaped plate 49, is rotatably mounted on the vertical plate 480. A telescopic motor 483, with its output shaft coaxially fixed to the drive rod 481, is mounted on the vertical plate 480. This allows the L-shaped plate 49 to move outward, adjusting the position of the scraper 47 to accommodate drilling and sampling requirements of different diameters, thus improving the accuracy and efficiency of sampling.

[0034] As a preferred embodiment, when the L-shaped plate 49 is attached to the vertical plate 480, the L-shaped plate 49 is completely located within the drill bit 45. This reduces interference during the drilling process, improves the overall compactness and safety of the drilling device, and facilitates the transportation and storage of the device.

[0035] When using the multifunctional mining drilling device of this utility model:

[0036] First, the device forms a stable support structure with two symmetrically arranged support legs 1 and a gantry frame 3, ensuring stability during the drilling process. Below the gantry frame 3 is a movable plate 33 that can move up and down. This movable plate 33 is driven by two hydraulic cylinders 34 symmetrically fixed to the bottom of the gantry frame 3. The vertical movement of the movable plate 33 is achieved by extending and retracting the piston rods of the hydraulic cylinders 34, thereby controlling the vertical position of the drill rod 4 and the drill bit 45.

[0037] At the bottom of the movable plate 33, a drill rod 4 is rotatably mounted, and a drill bit 45 that can move up and down is coaxially mounted at the bottom of the drill rod 4. The drill rod 4 is hollow, and several sampling components are installed inside above the drill bit 45 for simultaneous sampling during drilling. A threaded sleeve 46 is coaxially welded to the top of the drill bit 45, and a threaded rod 43 is threaded inside the threaded sleeve 46. The threaded rod 43 is rotatably connected to the drill rod 4 via a bearing. This design allows the drill bit 45 to maintain stable rotation while the depth of the drill bit 45 can be precisely controlled by rotating the threaded rod 43.

[0038] When drilling begins, the drilling motor 31 on top of the movable plate 33 starts, and its output shaft is fixed coaxially with the drill rod 4, providing a stable power source for the drill rod 4 and drill bit 45, thus automating the drilling process. During the rotation of the drill rod 4 and drill bit 45, the spiral guide groove 40 on their outer ring wall helps to smoothly discharge the debris and sampling materials generated during drilling, improving drilling efficiency and sampling quality, while reducing the risk of blockage inside the drill rod 4.

[0039] The sampling assembly plays a crucial role in the sampling process. The sampling assembly includes a disc 48 fixed near the bottom of the threaded sleeve 46. Several vertical plates 480 are fixedly mounted on the disc 48, and each vertical plate 480 has an L-shaped plate 49 that can move outwards. A scraper 47 is mounted on the L-shaped plate 49. When sampling is required, the telescopic motor 483 on the vertical plate 480 is activated, and the drive rod 481 rotates, causing the L-shaped plate 49 to move outwards, adjusting the position of the scraper 47 to adapt to different diameter boreholes and sampling needs. The scraper 47 scrapes rock or soil samples during drilling, thus achieving the sampling function.

[0040] In addition, the device also features angle adjustment. Both sides of the gantry 3 are rotatably connected to the outriggers 1 via connecting shafts 30. The connecting shafts 30 are fixed to the gantry 3, and the connecting shafts 30 and outriggers 1 are rotatably connected via bearings. This design allows for flexible adjustment of the angles of the gantry 3 and drill pipe 4, adapting to more complex drilling scenarios. An adjustment motor 32 is installed on one of the outriggers 1. The output shaft of the adjustment motor 32 is coaxially fixed to the connecting shaft 30. By controlling the start and direction of the adjustment motor 32, the angles of the gantry 3 and drill pipe 4 can be electrically adjusted, improving the automation level and ease of operation of the drilling device.

[0041] Finally, after drilling and sampling are completed, the threaded sleeve can be moved downwards by rotating the threaded rod 43, causing the drill bit 45 to disengage from the drill rod 4. This facilitates the extension of the sampling assembly from between the drill bit 45 and the drill rod 4 to retrieve the sampled material. Simultaneously, when the L-shaped plate 49 is attached to the vertical plate 480, it is completely located within the drill bit 45, reducing interference during drilling, improving the overall compactness and safety of the drilling device, and facilitating its transportation and storage.

[0042] In summary, the multifunctional mining drilling device of this utility model achieves efficient, stable, and flexible drilling and sampling functions through the working principles of hydraulic cylinder 34 driving movable plate 33 to move up and down, drilling motor 31 providing power, sampling component realizing sampling, threaded rod 43 and threaded sleeve 46 controlling the depth of drill bit 45, guide chute 40 discharging debris, cross plate 41 enhancing the stability of drill rod 4, and adjustment motor 32 realizing angle adjustment.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
