[0056] The supporting mechanism 300 comprises a mounting seat 31, a supporting seat 32, a supporting plate 33 and a diagonal brace assembly 34. The mounting seat 31 is fixed to one end of the base plate 21, and a guide hole 311 is formed in the middle position of the mounting seat 31. The guide hole 311 penetrates through the opposite two side surfaces of the mounting seat 31, and the guide hole 311 is coaxially arranged with the drill bit 411 and has a diameter slightly larger than the diameter of the drill bit 411.

[0057] The number of the supporting seats 32 is set according to requirements. For example, the number of the supporting seats 32 is two, and the two supporting seats 32 are spaced apart.

[0061] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , in an optional embodiment, the adjusting mechanism 200 further includes a first driving member 23, the adjusting assembly 22 includes a driving shaft 221, a first driven shaft 223, a second driven shaft 226, a support rod 224, a telescopic rod 227 and a first transmission assembly; the axes of the driving shaft 221, the first driven shaft 223 and the second driven shaft 226 are parallel to each other, one end of the support rod 224 is connected with the first driven shaft 223, and the other end is connected with the base plate 21; one end of the telescopic rod 227 is connected with the second driven shaft 226, and the other end is movably connected with the base plate 21.

[0062] The first driving member 23 is configured to drive the driving shaft 221 to rotate, and the driving shaft 221 drives the first driven shaft 223 and the second driven shaft 226 to rotate synchronously through the first transmission assembly, and in turn drives the support rod 224 to rotate around the axis of the first driven shaft 223 and the telescopic rod 227 to rotate around the axis of the second driven shaft 226.

[0063] Specifically, the driving shaft 221, the first driven shaft 223 and the second driven shaft 226 are arranged on the base 11 and have parallel axes, and the first driven shaft 223 and the second driven shaft 226 are located on opposite sides of the driving shaft 221. The first transmission assembly is not limited in structure, for example, the first transmission assembly includes a driving gear 222, a first driven gear 225 and a second driven gear 228. The driving gear 222 is mounted on the driving shaft 221, the first driven gear 225 is mounted on the first driven shaft 223, and the second driven gear 228 is mounted on the second driven shaft 226. The driving gear 222 is connected with the first driven gear 225 in meshing, and the driving gear 222 is connected with the second driven gear 228 in meshing. When the driving shaft 221 rotates, the first driven shaft 223 is driven to rotate through the meshing connection of the driving gear 222 and the first driven gear 225, and the second driven shaft 226 is driven to rotate through the meshing connection of the driving gear 222 and the second driven gear 228.

[0064] The support rod 224 can be a long strip-shaped square body, and the number of support rods 224 is set according to requirements. For example, the number of support rods 224 is two, and the two support rods 224 are arranged in the axial direction of the first driven shaft 223. One end of the support rod 224 can be fixedly connected with the first driven shaft 223 by welding, and the other end of the support rod 224 is movably connected with the bottom surface of the base plate 21. For example, the bottom surface of the base plate 21 is provided with a limiting groove, the other end of the support rod 224 is inserted into the limiting groove, and the other end of the support rod 224 is in clearance fit with the limiting groove. The other end of the support rod 224 can move slightly in the limiting groove.

[0065] The telescopic rod 227 can be a hydraulic telescopic rod or a pneumatic telescopic rod, and the number of telescopic rods 227 is set according to requirements. For example, the number of telescopic rods 227 is two, and the two telescopic rods 227 are arranged in the axial direction of the second driven shaft 226. The length of the telescopic rod 227 is adjustable, and the telescopic rod 227 includes a fixed rod and a movable rod in sliding connection with the fixed rod. The fixed rod is connected with the second driven shaft 226, and the end of the movable rod is hingedly connected with a movable seat mounted on the bottom surface of the base plate 21. The movable rod can slide along the fixed rod, and the height position of the base plate 21 close to the telescopic rod 227 is slightly adjusted through the extension or retraction of the movable rod, so that the base plate 21 is kept in a horizontal state.

[0066] The first driving component 23 can be a motor, defined as the first motor. The output shaft of the first motor is connected to the drive shaft 221. The first motor can rotate forward and reverse. The first motor drives the drive shaft 221 to rotate. The drive shaft 221 drives the first driven shaft 223 and the second driven shaft 226 to rotate synchronously through meshing drive gear 222, first driven gear 225, and second driven gear 228. The rotation directions of the first driven shaft 223 and the second driven shaft 226 are the same. For example, if the first driven shaft 223 and the second driven shaft 226 rotate toward the side closer to the drilling surface, it will drive the support rod 224 and the telescopic rod 227 to rotate toward the side closer to the drilling surface, thereby driving the base plate 21 to move downward in the vertical direction. For example, if the first driven shaft 223 and the second driven shaft 226 rotate toward the side farther from the drilling surface, it will drive the support rod 224 and the telescopic rod 227 to rotate toward the side farther from the drilling surface, thereby driving the base plate 21 to move upward in the vertical direction. Understandably, when the support rod 224 is perpendicular to the base 11, the base plate 21 moves to its highest position.

[0067] In this embodiment of the invention, the first driving member 23 drives the drive shaft 221 to rotate. The drive shaft 221 drives the first driven shaft 223 and the second driven shaft 226 to rotate synchronously through the first transmission assembly, thereby driving the support rod 224 and the telescopic rod 227 to rotate to a suitable position to adjust the height of the base plate 21. By adjusting the height of the base plate 21, the height of the drill bit 411 is adjusted so that the drill bit 411 is aligned with the marked position of the drill hole on the drilling surface. The support rod 224 and the telescopic rod 227 rotate to a suitable position, and the length of the telescopic rod 227 is adjusted to ensure that the base plate 21 is in a horizontal state, so that the drill bit 411 is perpendicular to the drilling surface. The adjustment mechanism 200 has a compact overall structure and can conveniently adjust the height and axial direction of the drill bit 411, ensuring the smooth progress of the drilling operation.

[0070] Specifically, the support mechanism 300 further includes a second driving member 36 and a second transmission assembly 35. The second driving member 36 can be a motor, defined as the second motor. The second transmission assembly 35 includes a driving rod 351, a driven rod 353, a driving gear 352, and a driven gear 354. The axis of the driving rod 351 is parallel to the axis of the driven rod 353, and both the driving rod 351 and the driven rod 353 are rotatably mounted on the mounting base 31. The driving gear 352 is mounted on the driving rod 351, and the driven gear 354 is mounted on the driven rod 353, with the driving gear 352 and the driven gear 354 meshing together. The second motor drives the driving rod 351 to rotate, and the driving rod 351 drives the driven rod 353 to rotate through the meshing driving gear 352 and the driven gear 354.

[0071] Two support seats 32 are symmetrically arranged about the center face of the mounting seat 31. A rotating rod 321 is provided at the first end of the support seat 32, which passes through the top and bottom ends of the support seat 32.

[0072] In this embodiment of the invention, the second driving member 36 drives the active rotating rod 351 to rotate. The active rotating rod 351 drives the driven rotating rod 353 to rotate via the second transmission assembly 35. The rotation of the active rotating rod 351 and the driven rotating rod 353 drives the two first transmission belts 355 to rotate. The rotation of the two first transmission belts 355 drives the two support seats 32 to rotate synchronously, so that the support seats 32 rotate 90 degrees and the support plate 33 at the second end of the support seat 32 abuts against the drilling surface; or so that the support seat 32 rotates into the receiving cavity of the mounting base 31. The rotation angle of the two support seats 32 can be easily adjusted by the second driving member 36 and the second transmission assembly 35.

[0073] like Figure 6 and Figure 7As shown, in an optional embodiment, two diagonal bracing assemblies 34 are respectively disposed at the top and bottom of the support base 32; the diagonal bracing assembly 34 includes a mounting rod 341, a support tube 342, a support column 343 and a limiting member 344, the mounting rod 341 is disposed on the support base 32, the support tube 342 is rotatably connected to the mounting rod 341, and the support column 343 is slidably connected to the support tube 342.

Multiple limiting grooves are spaced apart along the extension direction of the support column 343. The limiting member 344 is sequentially inserted through the limiting hole and a limiting groove to limit the support column 343. The end of the support column 343 is used to abut against the drilling surface.

[0075] Specifically, diagonal bracing assemblies 34 are installed at both the top and bottom of the support base 32. The diagonal bracing assembly 34 includes a mounting rod 341, a support tube 342, a support column 343, and a limiting member 344. The mounting rod 341 is located on the support base 32 and is placed horizontally. One end of the support tube 342 can be rotatably connected to the mounting rod 341 through a rotating sleeve. The rotating sleeve is fitted onto the mounting rod 341, and one end of the support tube 342 is fixedly connected to the outer wall surface of the rotating sleeve.

[0076] The support tube 342 has a limiting hole at the end opposite to the mounting rod 341. A section of the support column 343 is located inside the support tube 342. The support column 343 has multiple limiting grooves, the number of which is set according to requirements. The multiple limiting grooves are spaced apart along the length of the support column 343. The support column 343 is moved along the extension direction of the support tube 342 until the free end of the support column 343 abuts against the drilling face. Then, the limiting member 344 is inserted into the limiting hole and the limiting groove in sequence to fix and limit the support column 343.

[0077] Furthermore, the free end of the support column 343 is constructed with a conical head 345 so that after the support column 343 comes into contact with the drilling surface, the end of the conical head 345 can be embedded in the drilling surface, thereby improving the stability of the support.

[0078] In use, first rotate the two support bases 32 90 degrees so that the end faces of the two support plates 33 abut against the drilling surface. Then rotate the support pipe 342 to a target angle with the horizontal plane, for example, a target angle of 45 degrees, and move the support column 343 until the free end of the support column 343 abuts against the drilling surface. The support column 343 is then fixed by the limiting member 344. Each support base 32 is equipped with a diagonal brace assembly 34 at its top and bottom. The four diagonal brace assemblies 34 form point supports at four positions on the drilling surface, expanding the support area and further improving the stability of the support.

[0079] In this embodiment of the invention, the support tube 342 is rotatably connected to the mounting rod 341, the support column 343 is slidably connected to the support tube 342, and the limiting member 344 is inserted into the limiting hole of the support tube 342 and the limiting groove of the support column 343 to fix the support column 343. This allows for convenient adjustment of the tilt angle and length of the diagonal brace assembly 34, while also helping to further improve the stability of the support.

[0080] like Figure 6 and Figure 7 As shown, in an optional embodiment, the top and bottom of the support base 32 are provided with receiving grooves 322, and the diagonal brace assembly 34 can be housed in the receiving grooves 322.

[0081] Specifically, the support base 32 is provided with receiving grooves 322 at both the top and bottom. The size of the receiving grooves 322 is preferably large enough to accommodate the diagonal brace assembly 34. The receiving grooves 322 have two opposite side groove walls, a groove bottom surface, and a short groove wall connecting the two side groove walls. The two opposite ends of the mounting rod 341 are respectively connected to the two side groove walls.

[0082] After the drilling equipment is used, the diagonal brace assembly 34 can be stored in the receiving groove 322, and the bottom surface of the support tube 342 overlaps the bottom surface of the groove. The diagonal brace assembly 34 can be stored in the receiving groove 322 of the support base 32, and the support base 32 can be stored in the receiving cavity of the mounting base 31, which is beneficial to the compactness of the overall structure and also helps to protect the diagonal brace assembly 34.

[0083] like Figure 6 and Figure 7 As shown, in an optional embodiment, the support mechanism 300 further includes a telescopic member 37, a portion of which is embedded in the support base 32. One end of the telescopic member 37 is connected to a support tube 342, and the other end is connected to another support tube 342.

[0084] Specifically, a portion of the telescopic member 37 is embedded within the support base 32. The telescopic member 37 is capable of bidirectional telescopic expansion and contraction. One end of the telescopic member 37 is connected to the support tube 342 of the diagonal brace assembly 34 installed on the top of the support base 32, and the other end of the telescopic member 37 is connected to the support tube 342 of the diagonal brace assembly 34 installed on the bottom of the support base 32.

[0085] When the diagonal brace assembly 34 is in the retracted state, the two ends of the telescopic member 37 are flush with the bottom surfaces of the two receiving grooves 322. When the diagonal brace assembly 34 is deployed, the two ends of the telescopic member 37 extend, applying a thrust to the support tube 342, causing the support tube 342 to rotate around the axis of the mounting rod 341 until the support tube 342 rotates to the target angle. After the support tube 342 rotates to the target angle, the support column 343 abuts against the drilling face, and the length of the telescopic member 37 is relatively fixed. The telescopic member 37 ensures that the two support tubes 342 located at the top and bottom of the support base 32 are at the target angle to the horizontal plane, and at the same time, it can effectively reduce the shaking of the support tube 342 and support column 343 caused by the vibration of the drill bit 411 during drilling, further improving the stability of the support.

[0086] After the drilling operation is completed, the two ends of the telescopic component 37 retract, and the retraction action applies a pulling force to the support pipe 342, so that the support pipe 342 rotates around the axis of the mounting rod 341 toward the bottom surface of the receiving groove 322 until the two inclined bracing components 34 are respectively housed in the two receiving grooves 322.

[0087] In this embodiment of the invention, the two opposite ends of the telescopic member 37 are respectively connected to the support tubes 342 of the diagonal bracing assembly 34 at the top and bottom of the support base 32. The telescopic member 37 can extend and retract in both directions, which can conveniently expand or retract the diagonal bracing assembly 34, and at the same time help to further improve the stability of the diagonal bracing assembly 34.

[0088] like Figure 8 As shown, in an optional embodiment, the drilling mechanism 400 further includes a third driving member 43 and a movable slider 42; the base plate 21 is provided with a groove, and the movable slider 42 is slidably connected to the groove; the drilling rig 41 is disposed on the movable slider 42, and the movable slider 42 is connected to the third driving member 43, which is used to drive the movable slider 42 to slide along the groove.

[0089] Specifically, the top surface of the substrate 21 is provided with a sliding groove, the movable slider 42 is slidably connected to the sliding groove, and the movable slider 42 is connected to the driving end of the third driving member 43. The third driving member 43 can be a device capable of extending and retracting, such as a hydraulic cylinder, pneumatic cylinder, electric push rod, hydraulic telescopic rod, or pneumatic telescopic rod. The third driving member 43 can drive the movable slider 42 to slide along the sliding groove.

[0090] The drill bit 41 is mounted on the top surface of the movable slider 42. During drilling, the third drive unit 43 drives the movable slider 42 to move along the groove towards the drilling face, and the movable slider 42 drives the drill bit 41 to move towards the drilling face. After drilling is completed, the third drive unit 43 drives the movable slider 42 to move along the groove away from the drilling face, completing the withdrawal of the drill bit 411. The movable slider 42 and the groove contribute to the stability of the drill bit 41's movement, while the third drive unit 43 contributes to the convenience of the drill bit 41's movement.

[0091] like Figure 2 and Figure 8 As shown, in an optional embodiment, the drilling mechanism 400 further includes a plurality of limiting components 44, each of which includes a limiting slider 441 and a limiting rod 442; the top surface of the base plate 21 is also provided with a fixing seat 38, which is spaced apart from the mounting seat 31; one end of the limiting rod 442 is connected to the fixing seat 38 and the other end is connected to the mounting seat 31; the limiting slider 441 is slidably connected to the limiting rod 442, and the limiting slider 441 is fixedly connected to the movable slider 42.

[0092] Specifically, the fixing seat 38 is installed on the top surface of the base plate 21. The fixing seat 38 and the mounting seat 31 are spaced apart. Multiple limiting components 44 are provided between the fixing seat 38 and the mounting seat 31. The number of limiting components 44 is set according to actual needs. For example, two limiting components 44 are provided on each side of the movable slider 42. The two limiting components 44 on the same side are spaced apart in the vertical direction.

[0093] The limiting assembly 44 includes a limiting slider 441 and a limiting rod 442. One end of the limiting rod 442 is connected to the fixed base 38, and the other end is connected to the mounting base 31. The limiting slider 441 is sleeved on the limiting rod 442, and the limiting slider 441 and the limiting rod 442 are slidably connected. The limiting slider 441 and the movable slider 42 can be connected by welding, screwing, or snap-fitting. The limiting slider 441 can move synchronously with the movable slider 42. Multiple limiting sliders 441 can limit the movable slider 42 from the left and right directions and the up and down directions, ensuring the smooth movement of the movable slider 42, effectively avoiding deviation during movement, and thus improving the reliability of the drilling equipment.

[0094] like Figure 9 As shown, in an optional embodiment, the coal mine drilling device further includes a cleaning mechanism 500; the cleaning mechanism 500 is disposed on the mounting base 31, and the cleaning mechanism 500 includes a fourth drive member 52 and a plurality of cleaning components 51. The drilling rig 41 has a drill bit 411, and at least two cleaning components 51 are disposed on opposite sides of the drill bit 411.

[0095] The cleaning assembly 51 includes a cleaning rotating rod 511 and a cleaning roller brush 512. The cleaning roller brush 512 is disposed on the cleaning rotating rod 511. The fourth driving member 52 is used to drive the cleaning rotating rod 511 to rotate, thereby driving the cleaning roller brush 512 to rotate, and thus cleaning the drill bit 411.

[0096] Specifically, the cleaning mechanism 500 includes a fourth drive member 52 and multiple cleaning components 51. The number of cleaning components 51 is set according to requirements, for example, the number of cleaning components 51 may be two, four or more. The cleaning component 51 includes a cleaning rotating rod 511 and a cleaning roller brush 512. The cleaning roller brush 512 is disposed on the outer wall surface of the cleaning rotating rod 511, and the cleaning roller brush 512 may be a steel brush.

[0097] For example, there are four cleaning components 51, two above the drill bit 411 and two below it. These four components clean the soil adhering to the drill bit 411. After the drill bit 411 has drilled a certain depth along the drilling face, the soil adhering to it will affect drilling efficiency. At this point, the third drive unit 43 drives the moving slider 42 to move away from the drilling face until the drill bit 411 exits the drilling face. Then, the rotation of the four cleaning rollers 512 cleans the soil adhering to the drill bit 411. The fourth drive unit 52 drives the cleaning rotating rod 511 to rotate, which in turn rotates the cleaning rollers 512, facilitating the cleaning of the drill bit 411. The fourth drive unit 52 can be a motor.

[0098] After the cleaning operation is completed, drilling can continue. During the drilling operation, the soil attached to the drill bit 411 can be cleaned multiple times. Timely cleaning of the soil attached to the drill bit 411 during the drilling process helps to improve drilling efficiency. Multiple cleaning components 51 help to improve cleaning efficiency and cleaning effect.

[0099] like Figure 9 As shown, in an optional embodiment, the cleaning mechanism 500 further includes a third transmission assembly 53; the third transmission assembly 53 includes a transmission gear ring 531 and a second transmission belt 532. The transmission gear ring 531 is disposed at one end of the cleaning rod 511, and two adjacent transmission gear rings 531 are meshed together. The second transmission belt 532 is sleeved vertically on the other end of one cleaning rod 511 and the other end of the other cleaning rod 511.

[0100] Specifically, there are four cleaning components 51. Two cleaning components 51 are located above the drill bit 411, and two cleaning components 51 are located below the drill bit 411. The two cleaning components 51 located above the drill bit 411 are spaced apart in the horizontal direction, and the two cleaning components 51 located below the drill bit 411 are also spaced apart in the horizontal direction.

[0101] The third transmission assembly 53 includes transmission gear rings 531. Each of the four cleaning rotating rods 511 is equipped with a transmission gear ring 531. The transmission gear rings 531 are mounted on the first end of the cleaning rotating rods 511. Two transmission gear rings 531 located above the drill bit 411 are meshed together, and two transmission gear rings 531 located below the drill bit 411 are meshed together. A second transmission belt 532 is sleeved on two cleaning rotating rods 511 spaced apart in the vertical direction, and another second transmission belt 532 is sleeved on two other cleaning rotating rods 511 spaced apart in the vertical direction. The second transmission belt 532 is sleeved on the second end of the cleaning rotating rods 511.

[0102] The drive shaft of the third drive member 43 is connected to one of the cleaning rods 511. The third drive member 43 drives one cleaning rod 511 to rotate. One cleaning rod 511 can drive the other three cleaning rods 511 to rotate through four meshing transmission gear rings 531 and two second transmission belts 532. Thus, the four cleaning rods 511 rotate synchronously, driving the four cleaning roller brushes 512 to rotate synchronously, so as to clean the mud on the drill bit 411.

[0103] The meshing transmission gear ring 531 and the second transmission belt 532 contribute to the compactness of the cleaning mechanism 500 structure and also improve cleaning efficiency.

[0104] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
