Description

Technical Field

[0001] The utility model relates to the technical field of mining, in particular to a mining drill bit and a mining device. Background Art

[0002] Mining engineering is divided into coal mining and non-coal mining. Mining (English name: ore mining) is the technology and science of mining mineral resources from the earth's crust or surface. It generally refers to the mining of metal or non-metallic deposits. Mining in a broad sense also includes the mining and beneficiation of coal and oil. Its essence is a selective collection and transportation process of materials. The mining industry is an important raw material mining industry. For example, metal ores are the main raw materials of the metallurgical industry, non-metallic ores are chemical raw materials and building materials, and coal and oil are important energy sources. Most ores need to be beneficiated and enriched before they can be used as industrial raw materials.

[0003] The drill bit is a tool used to crush or drill harder ores. It effectively enables mining equipment to crush the ore by rotating the drill bit at high speed. However, due to its own working environment, it needs to frequently come into contact with harder ores to crush them, which leads to the need to use high-strength alloys in the production of the drill bit itself. However, under this condition, it is inevitable that the drill bit itself needs to be replaced frequently.

[0004] At present, most drill bits are screwed to the mining equipment through bolts or the threaded structure of the drill bit itself. Under this installation method, it is easy for the external bolts of the drill bit to collide with the ore and deform, resulting in difficulty in removing the bolts when the drill bit is subsequently disassembled, which increases the difficulty of assembling the drill bit. In addition, the drill bit is also prone to fall off during the high-speed rotation of the drill bit through the thread of the drill bit itself, affecting the construction progress and having a poor stabilization effect. Utility Model Content

[0005] Based on this, the purpose of the utility model is to provide a mining drill bit and a mining device, aiming to solve the problem that the existing drill bit has poor stability and is inconvenient to replace.

[0006] A mining drill bit provided in an embodiment of the utility model is arranged on the mining device, the mining device is provided with an output motor for connecting the drill bit, the mining drill bit comprises a mining output member connected to the output motor, and a drill bit assembly at least partially embedded in a side of the mining output member away from the output motor;

[0007] The drill head assembly includes an assembly component for connecting to the mining output member and a drill head assembly disposed on a side of the assembly component away from the mining output member;

[0008] The mining output member comprises an output end connected to the output motor, and a docking assembly extending outwardly from a side of the output end away from the output motor, an assembly groove for accommodating the assembly assembly is provided on a side of the docking assembly away from the output end, and a docking groove and a buckle groove adapted to at least part of the assembly assembly are respectively provided in the assembly groove;

[0009] The assembling component comprises a snap-fitting component which enters into the docking groove along the assembling groove to complete the snap-fitting, and a snap-fitting component which is at least partially embedded in the snap-fitting groove.

[0010] As described above, the clamping component can enter the docking groove along the assembly groove, and the drill bit assembly can be rotated clockwise to displace the clamping component and the docking groove and achieve clamping, thereby completing the rapid assembly of the drill bit assembly and the mining output component. The clamping component can be embedded in the clamping groove when the drill bit assembly and the mining output component are relatively rotated to limit the relative rotation of the drill bit assembly and the mining output component, thereby achieving the purpose of locking and ensuring the structural stability between the drill bit assembly and the mining output component. This solves the problem that most drill bits are currently screwed to the mining device through bolts or the threaded structure of the drill bit itself. Under this installation method, it is easy for the external bolts of the drill bit to collide with the ore and deform, resulting in the bolts being difficult to remove when the drill bit is subsequently disassembled, and the drill bit has poor stability and is not convenient to replace.

[0011] In addition, the mining drill bit proposed in the embodiment of the utility model may also have the following additional technical features:

[0012] Furthermore, the drill bit assembly includes a first fixing portion fixedly connected to the assembling assembly, a crushing portion arranged on a side of the first fixing portion away from the assembling assembly, and a penetrating portion extending outward along a side of the crushing portion away from the first fixing portion.

[0013] Furthermore, a plurality of spherical bumps for ore crushing extend outwardly from the outer surface of the crushing part.

[0014] Furthermore, the assembly component also includes a second fixing part fixedly connected to the first fixing part at a side away from the crushing part, and the second fixing part is provided with at least two sliding grooves for accommodating part of the buckle component.

[0015] Furthermore, the clamping component includes a fixing tube extending outwardly along the side of the second fixing portion away from the first fixing portion, and a clamping portion extending outwardly along the side of the fixing tube away from the second fixing portion. The shape of the clamping portion is adapted to the space in the assembly groove. After the clamping portion enters the assembly groove and then into the docking groove, it can rotate along the center of the docking groove so that the clamping portion completes the clamping in the docking groove.

[0016] Furthermore, the buckle component includes a sliding portion sleeved on the periphery of the second fixing portion and partially embedded in the sliding groove, a lifting portion arranged on the side of the sliding portion facing the clamping portion, and a positioning buckle arranged on the side of the lifting portion away from the sliding portion.

[0017] Furthermore, the second fixing portion is connected to the inner side of the fixing tube and is provided with an accommodating space for accommodating the lifting portion. The lifting portion is driven by the sliding portion to slide along a trajectory of the accommodating space, so that the lifting portion drives the positioning buckle to move toward or away from the buckle groove.

[0018] Furthermore, a plurality of elastic members are arranged on a side of the sliding portion away from the lifting portion.

[0019] In addition, the utility model also provides a mining device, comprising a mining drill bit arranged on the mining device. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] See also Figures 1 to 6 , shown is a mining drill bit in an embodiment of the utility model, which is arranged on a mining device, and an output motor for connecting the drill bit is arranged on the mining device. The mining drill bit includes a mining output member 2 connected to the output motor, and a drill assembly 1 at least partially embedded in the mining output member 2 on a side away from the output motor. It can be understood that the mining output member 2 is connected to the output motor on the mining device on one side and the drill assembly 1 is connected to the other side, so that the mining output member 2 and the drill assembly 1 can be driven to rotate by the output motor to implement the mining operation. The drill assembly 1 includes an assembly component 12 for connecting the mining output member 2 and an assembly component 12 arranged on the mining output member 2. The assembly component 12 is located away from the drill bit component 11 on one side of the mining output member 2. The mining output member 2 includes an output end 21 connected to the output motor, and a docking component 22 extending outwardly from the output end 21 away from the output motor. The docking component 22 is provided with an assembly groove 23 for accommodating the assembly component 12 on the side away from the output end 21. The assembly groove 23 is also provided with a docking groove 24 and a snap groove 25 respectively adapted to at least part of the assembly component 12. The assembly component 12 includes a snap-fitting component that enters into the docking groove 24 along the assembly groove 23 to complete the snap-fitting, and a snap-fitting component that is at least partially embedded in the snap groove 25.

[0033] Furthermore, the drill head assembly 11 includes a first fixing portion 111 fixedly connected to the assembly assembly 12, a crushing portion 112 arranged on a side of the first fixing portion 111 away from the assembly assembly 12, and a penetrating portion 113 extending outwardly along the side of the crushing portion 112 away from the first fixing portion 111, and a plurality of spherical protrusions for ore crushing extending outwardly from the outer surface of the crushing portion 112, the assembly assembly 12 also includes a second fixing portion 121 fixedly connected to the side of the first fixing portion 111 away from the crushing portion 112, and at least two sliding grooves 122 for accommodating part of the snap-fit ​​component are provided on the second fixing portion 121, and the snap-fit ​​component includes a fixing cylinder 124 extending outwardly along a side of the second fixing portion 121 away from the first fixing portion 111, and a snap-fitting portion 125 extending outwardly along a side of the fixing cylinder 124 away from the second fixing portion 121, and the shape of the snap-fitting portion 125 is adapted to the space in the assembly groove 23, wherein the snap-fitting portion 125 enters the assembly groove 23 until After being inserted into the docking groove 24, it can rotate along the center of the docking groove 24 so that the clamping part 125 can be clamped in the docking groove 24. The clamping part includes a sliding part 123 which is sleeved on the outer periphery of the second fixing part 121 and partially embedded in the sliding groove 122, a lifting part 126 which is arranged on the side of the sliding part 123 facing the clamping part 125, and a positioning buckle 127 which is arranged on the side of the lifting part 126 away from the sliding part 123. There are three positioning buckles 127 in total, and they are arranged in a triangular shape. The second fixing part 121 is connected to the inner side of the fixing cylinder 124 and is provided with an accommodating space for accommodating the lifting part 126. The lifting part 126 is driven by the sliding part 123 to slide along the trajectory of the accommodating space, so that the lifting part 126 drives the positioning buckle 127 to move toward or away from the clamping groove 25. A plurality of elastic members 128 are arranged on the side of the sliding part 123 away from the lifting part 126. In some optional embodiments, the elastic member 128 can be a spring or PU rubber.

[0034] In the specific implementation, first of all, it should be noted that in some optional embodiments of the present utility model, the mining output member 2 and the output shaft of the output motor on the mining device can be a fixed connection design or a detachable structure design. Then, when the operator needs to replace the drill assembly 1 regularly, the sliding part 123 can be held and pressed down in a direction away from the clamping part 125, wherein the sliding part 123 slides along the track of the slide groove 122. The specific structure of the sliding part 123 is as follows: Figure 6As shown, the lifting part 126 and the positioning buckle 127 at the center of the sliding part 123 are driven to slide in the downward pressing direction in turn, and the positioning buckle 127 is controlled to escape from the buckle groove 25. When the positioning buckle 127 is freed from the restriction of the buckle groove 25, it is embedded in the fixing tube 124, and the clamping part 125 located in the docking groove 24 in this state can rotate counterclockwise along the center of the docking groove 24. Then, the operator can rotate the clamping part 125 to a position matching the assembly groove 23, and then escape directly along the track in the assembly groove 23, thereby completing the separation of the drill assembly 1 and the mining output part 2.

[0035] For the assembly of the drill bit assembly 1, the operator prepares the drill bit assembly 1 to be replaced in advance, firstly aligns the clamping portion 125 with the assembly groove 23 and inserts it until it reaches the docking groove 24, and the protruding positioning buckle 127 is in a misaligned state with the clamping groove 25, so the positioning buckle 127 can be understood to be against the docking groove 24 and be in a state of being received in the fixing cylinder 124, then, the operator can rotate the drill bit assembly 1 and the mining output member 2 clockwise to make the clamping portion 125 rotate along the center of the docking groove 24 and be misaligned, thereby forming a clamping state, at the same time, in the process of relatively rotating the drill bit assembly 1 and the mining output member 2, the positioning buckle 127 and the clamping groove 2, which were originally in a misaligned state, are dislocated. 5 will be in a relative state, and under the influence of the tension of the elastic member 128, the sliding part 123, the lifting part 126 and the positioning buckle 127 can be pushed in sequence to move in the direction of the buckle groove 25, so that the positioning buckle 127 is rebounded into the buckle groove 25 to complete the locking, so as to prevent the drill bit assembly 1 and the mining output member 2 from rotating relative to each other, and complete the assembly work of the drill bit assembly 1 and the mining output member 2, the operation is simple and fast, further, through the set elastic member 128, the elastic force can be transmitted to the buckle groove 25 connected thereto through the positioning buckle 127, it can be understood that a shock absorbing structure is formed between the drill bit assembly 1 and the mining output member 2, which plays the purpose of protecting the drill bit assembly 1 and improving the service life of the drill bit assembly 1.

[0036] In addition, in some optional embodiments of the present invention, in order to prevent ore dust and the like from invading the second fixed portion 121 along the slide groove 122 during use of the drill bit assembly 1, causing the sliding portion 123 to be stuck and unable to slide, a cap adapted to the size of the space can be added to the slide groove 122, thereby effectively limiting the trajectory of the sliding portion 123 while preventing ore dust from invading the slide groove 122, thereby preventing the sliding portion 123 from sliding during use of the drill bit assembly 1 and causing the drill bit assembly 1 to loosen.

[0037] In summary, the clamping component can enter the docking groove 24 along the assembly groove 23, and the drill bit assembly 1 is rotated clockwise to make the clamping component and the docking groove 24 misaligned and clamped, thereby completing the rapid assembly of the drill bit assembly 1 and the mining output member 2. The clamping component can be embedded in the clamping groove 25 when the drill bit assembly 1 and the mining output member 2 are relatively rotated to limit the relative rotation of the drill bit assembly 1 and the mining output member 2, thereby achieving the purpose of locking and ensuring the structural stability between the drill bit assembly 1 and the mining output member 2. This solves the problem that most of the current drill bits are screwed with the mining device through bolts or the threaded structure of the drill bit itself. Under this installation method, it is easy to cause the external bolts of the drill bit to collide with the ore and deform, resulting in the bolts being difficult to remove when the drill bit is subsequently disassembled, and the drill bit has poor stability and is not convenient to replace.
