Annual output refers to the amount of ore produced by a mine each year. According to the size of the output, it is divided into three types: large, medium and small. In the existing mining process, most mining machines and mining equipment of various specifications are required. At the same time, the mining drill bits need to be replaced in real time under different geological environments to achieve efficient mining results.

[0003] Among them, the "drill bit for a mining drill rig that is easy to quickly disassemble and assemble" disclosed in the application number "202220703712.X" "includes a drill bit body, the upper end of the drill bit body is fixedly connected to the mounting seat, the upper end of the mounting seat is fixedly connected to the mounting column, a mounting groove is provided in the middle part of the upper end of the mounting column, the mounting groove is clamped to the fixing column, a fixing groove is provided in the fixing column, and a limiting mechanism is installed in the fixing groove". In the utility model, the mounting column and the fixing column can be quickly connected through the provided clamping block, spring, partition plate and other structures, and the provided fixing handle, threaded rod and fixing block and other structures can strengthen the fixation effect, which is convenient for the fixed use of the drill bit. When disassembling, it is only necessary to move the fixing block away from the mounting groove and put the clamping block into the fixing groove to complete the disassembly, which is very convenient.

[0004] However, the above method still has the following defects: during the drill bit disassembly process, the staff have to repeatedly rotate the screws on both sides, and then manually reversely rotate the mounting base and the drill bit installed thereon. This series of operations undoubtedly greatly increases the labor burden of the staff. The entire disassembly process is cumbersome and complicated. Not only is the operation quite difficult, but it also makes the drill bit disassembly work extremely difficult and time-consuming. Utility Model Content

A gear 8 is meshed and connected between the two rack plates 7. An adjusting component 9 is provided at the bottom end of the gear 8, which is convenient for driving the gear 8 to rotate.

[0025] The adjusting component 9 includes a rotating rod 901, which is fixedly mounted on the middle part of the bottom end of the gear 8. The bottom end of the rotating rod 901 is rotatably connected to the bottom end of the inner wall of the mounting seat 1. A worm gear 902 is fixedly provided on the middle part of the rotating rod 901. A worm 903 is meshed with one side of the worm gear 902, and one end of the worm 903 is rotatably connected to the inner wall of the mounting seat 1 through a bearing. The other end of the worm 903 passes through the mounting seat 1 and is provided with a rotating column 904. The surface of the rotating column 904 is provided with a number of evenly spaced anti-skid grooves. A mechanical seal is provided at the connection between the worm 903 and the mounting seat 1. By setting the adjusting component 9, the rotating column 904 is used to drive the worm 903 to rotate, and the structure is improved. The worm gear 902 is meshed with each other, thereby driving the rotating rod 901 to rotate, and then driving the gear 8 at the top of the rotating rod 901 to rotate. With the arrangement of the two rack plates 7, it is convenient to move the two rack plates 7 and the two movable plates 5 synchronously in opposite directions, so that the tightly plugged plug block 6 and the slot 11 are separated from each other, and combined with the clamping column 2, it is convenient to quickly disassemble the drill body 3. During the installation and removal of the drill body 3, the user only needs to rotate the rotating column 904 forward or reverse, which greatly reduces the labor burden of the staff. The entire disassembly process is convenient and easy to operate, and the drill bit disassembly work becomes easy and quick.

[0026] The bottom end of the mounting base 1 is provided with a mounting assembly 12, which includes a mounting plate 1201. The mounting plate 1201 is fixedly mounted on the bottom end of the mounting base 1. The surface of the mounting plate 1201 is threadedly connected to a plurality of evenly spaced screws 1202, and the top ends of the screws 1202 are fixedly provided with bolt caps 1203. Through the provided mounting assembly 12, the screws 1202 are combined with the bolt caps 1203 and matched with the screw holes to connect and fix the drilling equipment.

[0027] A limiting ring 13 is fixed to the bottom of the drill body 3, and the bottom end of the limiting ring 13 fits with the top of the mounting seat 1. The limiting ring 13 can limit the installation of the drill body 3. A slot 15 is provided on the top of the mounting seat 1 to engage with the clamping column 2, so that the clamping column 2 is plugged into the slot 15. A retaining plate 14 is fixed to the top of the inner wall of the mounting seat 1, and the retaining plate 14 is slidably connected to the clamping column 2. The retaining plate 14 can limit the installation of the clamping column 2.

[0028] Support springs 10 are sleeved on both sides of the guide plate 4. One end of the support spring 10 is fixedly connected to the other side of the movable plate 5, and the other end is fixedly connected to the inner wall of the mounting base 1. The support spring 10 is provided so as to facilitate the stabilization of the movement of the movable plate 5 and improve the stability of the movable plate 5 during the movement process.

[0029] When in use, first use the bolt cap 1203 and the screw 1202 to install the mining drill bit on the surface of the relevant drilling rig, and then use the drill body 3 to mine the mine. When the drill body 3 needs to be disassembled, the user only needs to rotate the set rotating column 904 to drive the worm 903 to rotate forward, and combine with the meshing worm wheel 902 to drive the worm wheel 902 to rotate synchronously, thereby driving the rotating rod 901 and the gear 8 to rotate synchronously. Since the two rack plates 7 are meshingly connected with the gear 8, the rotation of the gear 8 drives the two rack plates 7 to rotate synchronously. The second step moves in the opposite direction, so that the two movable plates 5 slide in opposite directions on the surface of the guide plate 4. At this time, the support spring 10 is in a compressed state, and the plug-in block 6 and the slot 11 at the clamping column 2, which are closely plugged into each other, are separated from each other. Combined with the clamping column 2, it is convenient to quickly disassemble and remove the drill body 3, and it is convenient to disassemble and maintain the drill body 3. During this process, the user only needs to rotate the set rotating column 904 in the forward and reverse directions to realize the disassembly or installation operation of the drill body 3, which greatly reduces the labor intensity of the staff; finally, repeat the above steps to install the replaced drill body 3.
