Description

Technical Field

[0001] This utility model relates to the field of drilling, specifically to an ore drilling device. Background Technology

[0002] In the field of ore exploration and mining, sampling and analysis are crucial for accurately understanding ore characteristics. Currently, ore sampling commonly uses drilling to obtain samples, but the complexity of ore layers presents numerous challenges. Influenced by geological sedimentation and mineralization, the hardness of ore layers exhibits significant stratification differences, ranging from soft veins to hard rock formations. Drill bits cannot adjust drilling pressure in real time during drilling. When the drill bit encounters a hard ore layer, the instantaneous high-load stress is difficult to release, easily leading to drill bit wear, chipping, or even breakage. This not only affects sampling efficiency and quality but also significantly increases equipment wear and operating costs, hindering the efficient advancement of ore exploration. Utility Model Content

[0003] In view of the problems in the prior art, this utility model provides an ore drilling device.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an ore drilling device, including two supports, a crossbeam installed on the supports, a second cylinder installed on the crossbeam, a moving plate connected to the second cylinder, a buffer assembly installed on the moving plate, a connecting plate installed on the buffer assembly, a servo motor installed on the connecting plate, and a drill bit connected to the output end of the servo motor. When the drill bit is obstructed during drilling, the buffer assembly retracts.

[0005] Preferably, the buffer assembly includes at least two support rods disposed on the movable plate, each support rod having an elastic element and at least two limiting grooves, and the support rods sliding on the connecting plate without separating.

[0006] Preferably, it further includes a fixing ring disposed on the support rod, the fixing ring having an installation groove in the middle, and an inwardly protruding limiting block disposed inside the fixing ring, the support rod passing through the interior of the installation groove, and the limiting block being engaged inside the limiting groove; the fixing ring is provided with a slot, and a fastening bolt is installed inside the slot, the fastening bolt being used to adjust the hole size of the installation groove.

[0007] Preferably, the elastic element is located below the retaining ring to release pressure.

[0008] Preferably, a first cylinder is provided on the crossbeam, and the telescopic end of the first cylinder is connected to the second cylinder for adjusting the position of the second cylinder on the crossbeam.

[0009] Beneficial effects:

[0010] The extension of the second cylinder causes the moving plate to move downwards, which in turn causes the buffer assembly to move downwards synchronously. The buffer assembly then causes the connecting plate to move downwards synchronously, which in turn causes the servo motor to move downwards synchronously. The servo motor drives the drill bit to rotate. When the drill bit contacts the ore, it is subjected to downward pressure. Under the action of the second cylinder, the drill bit is constantly subjected to downward pressure, and the drill bit will continue to drill. When encountering harder ore, in order to prevent damage to the drill bit, the buffer assembly retracts, and the servo motor and the drill bit move upwards with the connecting plate. This prevents the drill bit from continuing to be subjected to downward pressure and failing to drill into the ore, thus avoiding damage. This has a good effect on protecting the drilling drill bit.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] In one embodiment, please refer to the appendix to the specification. Figure 1-3 As shown, the ore drilling device of this utility model includes two supports 1. A crossbeam 10 is installed on the support 1. A second cylinder 3 is provided on the crossbeam 10. A moving plate 4 is connected to the second cylinder 3. A buffer assembly 5 is installed on the moving plate 4. A connecting plate 8 is installed on the buffer assembly 5. A servo motor 7 is provided on the connecting plate 8. A drill bit 9 is connected to the output end of the servo motor 7. When the drill bit 9 is obstructed during drilling, the buffer assembly 5 retracts.

[0018] The extension of the second cylinder 3 causes the moving plate 4 to move downwards. The moving plate 4 then causes the buffer assembly 5 to move downwards synchronously. The buffer assembly 5, in turn, causes the connecting plate 8 to move downwards synchronously. The downward movement of the connecting plate 8 causes the servo motor 7 to move downwards synchronously. The servo motor 7 drives the drill bit 9 to rotate. When the drill bit 9 contacts the ore, it is subjected to downward pressure. Under the action of the second cylinder 3, the drill bit 9 is always subjected to downward pressure, and the drill bit 9 will continue to drill. When encountering harder ore, in order to prevent damage to the drill bit 9, the buffer assembly 5 retracts. The servo motor 7 and the drill bit 9 move upwards with the connecting plate 8, preventing the drill bit 9 from continuing to be subjected to downward pressure and failing to drill into the ore, thus providing a good protection for the drilling drill bit 9.

[0019] The buffer assembly 5 includes at least two support rods 53 disposed on the movable plate 4. Each support rod 53 is provided with an elastic element 52 and at least two limiting grooves 51 are provided on the support rod 53. The support rod 53 slides on the connecting plate 8 without separating.

[0020] When the elastic element 52 is squeezed by the connecting plate 8, the elastic element 52 contracts, thereby achieving the function of force relief and buffering.

[0021] It also includes a retaining ring 6 disposed on the support rod 53. The retaining ring 6 has a mounting groove 64 in its center. An inwardly protruding limiting block 63 is disposed inside the retaining ring 6. The support rod 53 passes through the interior of the mounting groove 64, and the limiting block 63 is engaged within the limiting groove 53. A slot 61 is provided on the retaining ring 6, and a fastening bolt 62 is installed inside the slot 61. The fastening bolt 62 is used to adjust the diameter of the hole in the mounting groove 64. The elastic element 52 is located below the retaining ring 6 and is used to release pressure.

[0022] To further adjust the buffer stroke, the fastening bolt 62 (which can be a bolt) can be removed. By tightening the fastening bolt 62, the fixing ring 6 is pulled tight. The fixing ring 6 will press the limiting block 63 on its inner wall into the limiting groove 51. After the fastening bolt 62 is tightened, the fixing ring 6 will not rotate or move up and down on the support rod 53. When the adjusted stroke is too large, multiple elastic elements 52 can be added below the fixing ring 6 to cooperate with the drilling of the drill bit 9.

[0023] A first cylinder 2 is provided on the crossbeam 10. The telescopic end of the first cylinder 2 is connected to the second cylinder 3, which is used to adjust the position of the second cylinder 3 on the crossbeam 10.

[0024] The position of drill bit 9 when drilling on the ore can be adjusted.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model.
