Detailed Implementation

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figures 1 to 15 In this embodiment of the invention, a mining drilling machine has a drilling mechanism 6, which includes a connecting seat 7 and a C-shaped fixing seat 8 fixed inside the connecting seat 7; a vertical cylinder 9 is fixed inside the C-shaped fixing seat 8, and a drilling drive assembly 15 is slidably connected to the outside of the vertical cylinder 9; the drilling drive assembly 15 is driven by a lifting motor 10, a plate chain 11 and a sprocket 13. A rotary mechanism 17 is provided below the drilling drive assembly 15. The rotary mechanism 17 includes an arc-shaped top frame 171 fixed to the C-shaped fixing seat 8 by a hanger 172. The arc-shaped top frame 171 has teeth on one side inside and is meshed with a drive gear 173. The drive gear 173 is installed on the output shaft of the drive motor 174 located inside the drill rod shaft 175. The bottom of the drill rod shaft 175 is connected to a rotary cylinder 176. The rotary cylinder 176 is installed inside a frustum 177. A roller 178 is installed at the bottom of the frustum 177 and is slidably connected to an arc-shaped base frame 179. The arc-shaped base frame 179 is fixed on the base plate 20. A plurality of U-shaped grooves 1710 are also provided around the outside of the frustum 177. A drill rod storage box 18 is also fixed on the base plate 20, and two feed cylinders 19 are fixed on the side of the drill rod storage box 18.

[0035] By adopting the above technical solution, during use, the drill rod with the drill bit is first installed on the drilling drive assembly 15. When the drill rod is used up, the drive assembly 15 rises to a certain height, and the drive motor 174 drives the drive gear 173 to rotate. The drive gear 173 then meshes with the teeth on the inner side of the arc-shaped top frame 171, causing the drive gear 173 and the drill rod shaft 175 to move along the arc-shaped base frame 179. This allows the drill rod shaft 175 to slide directly below the drive assembly 15. Subsequently, the drive assembly 15 moves down, allowing the drill rod 16 to be inserted into the drive assembly 15. Then, the drill rod with the drill bit is connected, enabling drilling into deep mines.

[0036] Please see the appendix Figure 5-6 , Figure 9 and Figure 11 In this embodiment, a U-shaped through groove is provided on the frustum 177. When the drill rod 16 is connected, the U-shaped through groove is located directly below the drilling drive assembly 15. A housing 1711 is also fixed to the outside of the drill rod shaft 175.

[0037] By adopting the above technical solution, the U-shaped through groove on the frustum 177 can ensure that the drill rod 16 can be connected with the previous drill rod; the outer shell 1711 is designed to ensure that the drill rod 16 can be stably placed in the U-shaped groove 1710 when the drill rod shaft 175 carries the drill rod 16 to rotate, so as to avoid slippage.

[0038] Please see the appendix Figure 14 In this embodiment, the drill rod storage box 18 is flat at one end and arc-shaped at the other end, with a rod outlet at the arc end. An arc-shaped stop 18a is provided on one side of the rod outlet, and a locking post 18b is provided on the other side.

[0039] Furthermore, after the drill rod shaft 175 slides along the arc-shaped top frame 171 and the arc-shaped bottom frame 179, a U-shaped groove 1710 on the drill rod shaft 175 fits into the rod outlet at one end of the drill rod storage box 18; then the arc-shaped stop 18a fits into the outside of the drill rod shaft 175.

[0040] By adopting the above technical solution, when the drill rods in the drill rod shaft 175 are used up, the drill rod shaft 175 moves to the drill rod storage box 18, the cylinder rod of the feeding cylinder 19 extends, causing the inner drill rod 16 to move towards the opening and squeeze the outermost drill rod 16. The outermost drill rod 16 squeezes the retaining post 18b and disengages from the inside, thus entering the U-shaped groove 1710. Subsequently, the rotating cylinder 176 drives the drill rod shaft 175, causing the drill rod 16 to enter the outer casing 1711 to prevent it from falling out.

[0041] In this embodiment, the width of the internal cavity of the drill rod storage box 18 is not less than the diameter of the drill rod; the retaining post 18b is made of rubber.

[0042] By adopting the above technical solution, the drill rod 16 inside the drill rod storage box 18 can only break through the chuck 18b and enter the U-shaped groove 1710 under the action of thrust; at the same time, it can be ensured that the drill rod 16 will not fall off by itself when the equipment is working.

[0043] Please see the appendix Figure 4-7 , Figure 12 and 13 In this embodiment, the drilling drive assembly 15 includes an upper clamp 151 and a lower clamp 152 fixed to the slide 12. A drilling cylinder 153 is fixed on the upper clamp 151, and a fixed cylinder 154 is clamped and fixed inside the lower clamp 152. A rotating cylinder 155 is rotatably connected below the fixed cylinder 154. A plurality of rubber movable clips 156 are movably connected inside the rotating cylinder 155.

[0044] The slide 12 is riveted and fixed to the plate chain 11, and the slide 12 is also slidably connected to the slide rail 14; there are two slide rails 14, which are symmetrically fixed on both sides of the vertical cylinder 9.

[0045] By adopting the above technical solution, when automatically changing the drill rod 16, the rotary cylinder 176 drives the drill rod shaft 175 to rotate at a predetermined angle, so that the drill rod 16 accurately falls above the previously drilled drill rod through the U-shaped groove on one side of the frustum 177; then, the lifting motor 10, through the cooperation of the sprocket 13 and the plate chain 11, drives the slide 12 to move downward along the slide rail 14 and the guide rod until the rotating cylinder 155 contacts the top of the drill rod 16 in the U-shaped groove 1710. Under the action of downward pressure, the top of the drill rod 16 is inserted into the rotating cylinder 155, and the drill rod 16 is temporarily fixed by the clamping of the rubber movable clamp 156; at this time, the rotary mechanism 17 can return along the original path to avoid interference when the drill rod 16 is drilling.

[0046] Furthermore, the upper end of the rotating cylinder 155 has a square neck hole; the upper end of the drill rod 16 has a square neck, and a stud is provided at the top of the square neck; the lower end of the drill rod 16 has a threaded hole.

[0047] A gear ring 157 is fitted on the outer side of the rotating cylinder 155. The gear ring 157 meshes with a gear 158, which is fitted on a rotary motor 159. The rotary motor 159 is fixed to the outer side of the lower clamp 152 via a motor base.

[0048] The two drill rods 16 are screwed in the same direction as the rotating cylinder 155.

[0049] By adopting the above technical solution, after the rotary mechanism 17 is withdrawn, the rotary motor 159 drives the rotary cylinder 155 to rotate under the cooperation of the gear 158 and the gear ring 157. Since the two drill rods are connected by threads, their friction is greater than the clamping force of the rubber movable clamp 156. When rotating, the rotary cylinder 155 will rotate relative to the drill rod 16. When the square neck at the top of the drill rod 16 coincides with the square neck hole in the rotary cylinder 155, it will be locked into the square neck hole. At this time, the driving force of the rotary cylinder 155 on the drill rod 16 increases. Since the screwing direction of the drill rod 16 is consistent with the rotation direction of the rotary cylinder 155, the two drill rods 16 will be screwed tightly together. During the drilling process, the two drill rods will become tighter and tighter, and there will be no situation where the rods come off.

[0050] Please see the appendix Figure 9 and Figure 11 In this embodiment, the bottom of the frustum 177 is also connected to two side wheels 1712 via a pivot. The two side wheels 1712 are located on both sides of the frustum 177 and are attached to the inner and outer sides of the arc-shaped base frame 179.

[0051] By adopting the above technical solution, the setting of the two side wheels 1712 can ensure that the frustum 177 can maintain its original state when it moves, ensuring the stability of its movement, and further ensuring the positioning accuracy of the U-shaped groove on the frustum.

[0052] In this embodiment, a stop frame 21 is also fixed to the bottom of the base plate 20; multiple connecting rods 22 are fixed to the upper end of one side of the base plate 20; the upper end of the connecting rod 22 is fixedly connected to the connecting seat 7. The drilling mechanism 6 is fixedly installed on the forearm mechanism 5, and the forearm mechanism 5 is installed in conjunction with the main boom mechanism 4; one end of the main boom mechanism 4 is attached to the main body 1 of the engineering vehicle; side support mechanisms 3 are also provided on both sides of the main body 1 of the engineering vehicle, and a driver's seat 2 is also fixed on the main body 1 of the engineering vehicle.

[0053] The stop frame 21 is abutted against the mine body, which ensures the stability of the drill rod during drilling when the equipment is working.

[0054] The working principle is as follows: During use, the drill rod with the drill bit is first installed on the drilling drive assembly 15. When the drill rod is used up, the drive assembly 15 rises to a certain height, and the drive motor 174 drives the drive gear 173 to rotate. The drive gear 173 then meshes with the teeth on the inner side of the arc-shaped top frame 171, causing the drive gear 173 and the drill rod shaft 175 to move along the arc-shaped base frame 179. This allows the drill rod shaft 175 to slide to the bottom of the drive assembly 15. Then, the drive assembly 15 moves down, allowing the drill rod 16 to be inserted into the drive assembly 15. The drill rod with the drill bit is then connected, enabling drilling into deep mines. When automatically changing drill rod 16, rotary cylinder 176 drives drill rod shaft 175 to rotate by a predetermined angle, so that drill rod 16 falls precisely above the previously drilled drill rod through the U-shaped groove on one side of frustum 177; then, lifting motor 10, through the cooperation of sprocket 13 and plate chain 11, drives slide 12 to move downward along slide rail 14 and guide rod until rotating cylinder 155 contacts the top of drill rod 16 in U-shaped groove 1710. Under the action of downward pressure, the top of drill rod 16 is inserted into rotating cylinder 155, and the drill rod 16 is temporarily fixed by the clamping of rubber movable clip 156; at this time, rotary mechanism 17 can return along the original path to avoid interference when drill rod 16 is drilling; After the rotary mechanism 17 is withdrawn, the rotary motor 159, in cooperation with the gear 158 and the gear ring 157, drives the rotary cylinder 155 to rotate. Since the two drill rods are connected by threads, their friction is greater than the clamping force of the rubber movable clamp 156. During rotation, the rotary cylinder 155 will rotate relative to the drill rod 16. When the square neck at the top of the drill rod 16 coincides with the square neck hole in the rotary cylinder 155, it will be engaged in the square neck hole. At this time, the driving force of the rotary cylinder 155 on the drill rod 16 increases. Since the screwing direction of the drill rod 16 is consistent with the rotation direction of the rotary cylinder 155, the two drill rods 16 will be tightly engaged. During drilling, the two drill rods will become increasingly tight, and there will be no situation where the rods come off. The automatic rod-adding method can ensure that the drilling machine can drill deep into the mine and meet the usage requirements.
