Description

Technical Field

[0001] This utility model relates to the field of mining tool drilling technology, specifically a mining drilling device. Background Technology

[0002] Mining ventilation ducts often need to be suspended in a fixed position by a hanging edge to achieve ventilation. The hanging edge is usually equipped with a hanging ring. In the existing technology, a round hole is first punched in the hanging edge, and then a metal ring is inlaid on the edge of the round hole. However, the hanging edge is prone to tilting when drilling. Therefore, existing technology can use a drilling device to drill holes in the hanging edge.

[0003] For example, an existing Chinese patent (publication number: CN218081762U) discloses a workpiece drilling device. By setting a filter screen, the waste chips and cutting fluid generated during drilling can be separated to prevent the waste chips from clogging the conveying pipe. The sliding rail makes it easier for workers to remove the filter screen and facilitates disassembly and assembly. A handle is also fixedly set on one side of the filter screen.

[0004] However, the workpiece drilling device designed above still has some problems in actual use. Although the workpiece drilling device can conveniently drill holes in the workpiece and can separate the waste chips and cutting fluid generated by the filter screen during drilling, the cleaning of the filter screen needs to be done manually. Manual cleaning is inconvenient, and this process is not only time-consuming and laborious, but also poses certain safety hazards due to the sharpness of the metal chips. Utility Model Content

[0005] The purpose of this invention is to provide a drilling device for mining to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a mining drilling device, including a drilling platform and a receiving groove opened at the top center of the drilling platform. A first filter screen is rotatably arranged in the receiving groove, and a second filter screen is arranged on top of the first filter screen. An electric push rod is rotatably arranged between the inner side wall of the receiving groove and the bottom side of the first filter screen. A fixing port and a slag receiving cavity are also opened in the drilling platform. The receiving groove, the fixing port and the slag receiving cavity are connected. One end of the first filter screen is engaged with one side of the fixing port.

[0007] Furthermore, a rotating shaft is fixedly installed inside the receiving trough, and the first filter screen is rotatably sleeved on the rotating shaft. An mounting base and a fixing base are fixedly installed between the inner side wall of the receiving trough and the bottom side of the first filter screen, respectively. The two ends of the electric push rod are respectively rotatably arranged in the mounting base and the fixing base.

[0008] Furthermore, a first pin is provided in the mounting base, a second pin is provided in the fixing base, and the two ends of the electric push rod are respectively rotatably sleeved on the first pin and the second pin.

[0009] Furthermore, a first limiting member is fixedly installed on one side wall of the receiving trough, the first limiting member being located diagonally below the fixing opening, and a second limiting member is fixedly installed on the other side wall of the receiving trough, the top of the second limiting member abutting against the bottom of the first filter screen.

[0010] Furthermore, a cleaning port is provided at one end of the front side of the drilling platform. The cleaning port is connected to the slag receiving chamber, and a slag receiving hopper is slidably inserted into both the cleaning port and the slag receiving chamber.

[0011] Furthermore, it also includes a drilling assembly, which includes a gantry frame fixedly installed on the top of the drilling table. A fixing frame is provided on the front side of the gantry frame, and a motor is provided on the fixing frame. A drilling cutter is fixedly installed on the drive shaft of the motor. A cylinder is also provided on the top of the fixing frame, and the drive end of the cylinder passes through the fixing frame and is fixedly connected to the top of the motor.

[0012] Furthermore, it also includes a lubrication assembly, which includes a water tank containing clean water. The water tank is fixedly installed on the rear side of the drilling table. A hose is fixedly inserted into the bottom of one side of the water tank. A water spray head is provided on the side of the motor away from the drive end. The water spray head is inclined and faces the bottom end of the drilling tool. The other end of the hose is fixedly inserted into the water spray head.

[0013] Furthermore, it also includes a water circulation component, which includes a circulation pipe. One end of the circulation pipe is fixedly inserted into the bottom of the rear side of the drilling table and is connected to the receiving trough. The other end of the circulation pipe is fixedly inserted into the top of the rear side of the water storage tank. A water pump is installed on the circulation pipe.

[0014] Furthermore, a gap is left between the first filter screen and the second filter screen, and a support spring and a telescopic rod are provided. A contact block and an electromagnetic button are also provided between the first filter screen and the second filter screen. The contact block and the electromagnetic button cooperate to abut against each other, and the electromagnetic button is electrically connected to the electric push rod.

[0015] Furthermore, the number of support springs is six, and the number of telescopic rods corresponds to the number of support springs. The six support springs and telescopic rods are fixedly installed at equal intervals at both ends between the first filter screen and the second filter screen.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting a first filter screen and a second filter screen, the sewage and metal impurities falling into the receiving tank can be easily separated into solid and liquid states. By turning on the electric push rod, the drive end of the electric push rod can be extended to push the first filter screen and the second filter screen to rotate around the rotating shaft. Subsequently, the metal impurities will slide into the slag receiving chamber along the inclined second filter screen, thus achieving the effect of electric cleaning of metal impurities from the second filter screen. This reduces the workload of personnel and avoids the safety hazard caused by direct contact between metal impurities and personnel's hands.

[0017] When metallic impurities continuously fall onto the top of the second filter, they generate downward pressure. When the second filter moves the contact block against the electromagnetic button, the electromagnetic button sends an electrical signal to the electric push rod through the circuit, causing the electric push rod to automatically open and extend its drive end to a set distance. This causes the first and second filters to rotate at a fixed angle, thus achieving adaptive and automatic cleaning of metallic impurities on the top of the second filter, which can further improve the cleaning effect.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-5 This utility model provides a technical solution: a mining drilling device, including a drilling platform 1 and a receiving groove 2 opened at the top center of the drilling platform 1. A first filter screen 3 is rotatably arranged in the receiving groove 2, and a second filter screen 4 is arranged on the top of the first filter screen 3. An electric push rod 5 is rotatably arranged between the inner side wall of the receiving groove 2 and the bottom side of the first filter screen 3. A fixing port 6 and a slag receiving cavity 7 are also opened in the drilling platform 1. The receiving groove 2, the fixing port 6 and the slag receiving cavity 7 are connected. One end of the first filter screen 3 is engaged with one side of the fixing port 6.

[0026] A rotating shaft 8 is fixedly installed inside the receiving trough 2. The first filter screen 3 is rotatably sleeved on the rotating shaft 8. An mounting base 9 and a fixing base 10 are fixedly installed between the inner side wall of the receiving trough 2 and the bottom side of the first filter screen 3, respectively. The two ends of the electric push rod 5 are rotatably set in the mounting base 9 and the fixing base 10, respectively. A first pin is set in the mounting base 9 and a second pin is set in the fixing base 10. The two ends of the electric push rod 5 are rotatably sleeved on the first pin and the second pin, respectively.

[0027] In practice, the wastewater and metal shavings after use will fall into the receiving tank 2 together. At this time, the cooperation of the first filter screen 3 and the second filter screen 4 can separate the solid and liquid. When there are too many metal impurities on the top of the second filter screen 4, the electric push rod 5 is turned on, which can extend the drive end of the electric push rod 5, so that the first filter screen 3 drives the second filter screen 4 to rotate around the rotating shaft 8. At this time, the impurities will slide into the slag receiving chamber 7 along the inclined second filter screen 4, thus realizing the effect of electric cleaning of metal impurities on the second filter screen 4, reducing the workload of personnel, and avoiding the problem of scratches caused by direct contact between metal impurities and personnel's hands.

[0028] In addition, rubber rings are fitted around the outside of both the first filter screen 3 and the second filter screen 4. Since the rotation of the first filter screen 3 and the second filter screen 4 will produce an arc, and the rubber rings have a certain elasticity, they can prevent the first filter screen 3 and the second filter screen 4 from abutting against the inner wall of the receiving trough 2 when they rotate, thus avoiding motion interference and ensuring the normal operation of the punching device.

[0029] It should be noted that for electric linear actuator 5, we prefer to use the FD1 model. The FD1 series electric linear actuator is an electric drive device that converts the rotary motion of an electric motor into linear reciprocating motion. The ultimate load can reach 6000N (approximately 612kg), and the no-load running speed is 5mm / s to 35mm / s. It is driven by a 12V / 24V DC permanent magnet motor. Since electric linear actuator 5 is existing technology and is not a problem that needs to be solved in the background technology of this specification, it will not be elaborated on further.

[0030] See Figure 1-5 A first limiting member 11 is fixedly installed on one side wall of the receiving trough 2, located diagonally below the fixing port 6. A second limiting member 12 is fixedly installed on the other side wall of the receiving trough 2, with the top of the second limiting member 12 abutting against the bottom of the first filter screen 3. This facilitates limiting the rotation of the first filter screen 3. When the first filter screen 3 abuts against the first limiting member 11, metal impurities can easily slide into the slag receiving chamber 7 along the second filter screen 4. When the first filter screen 3 abuts against the second limiting member 12, the first filter screen 3 and the second filter screen 4 can easily reset, thus filtering metal impurities and wastewater.

[0031] See Figure 1-5 A cleaning port 14 is provided at one end of the front side of the drilling platform 1. The cleaning port 14 is connected to the slag receiving chamber 7, and a slag receiving hopper 13 is slidably inserted into both the cleaning port 14 and the slag receiving chamber 7. By setting up the slag receiving hopper 13, it is easy to collect the impurities that slide down the second filter screen 4. By pulling the slag receiving hopper 13, the slag receiving hopper 13 can be pulled out from the cleaning port 14, making it convenient for personnel to recycle and process the impurities collected in the slag receiving hopper 13.

[0032] See Figure 1-5 It also includes a drilling assembly, which includes a gantry frame 15. The gantry frame 15 is fixedly installed on the top of the drilling table 1. A fixing frame 16 is provided on the front side of the gantry frame 15. A motor 17 is provided on the fixing frame 16. A drilling cutter 18 is fixedly installed on the drive shaft of the motor 17. A cylinder 28 is also provided on the top of the fixing frame 16. The drive end of the cylinder 28 passes through the fixing frame 16 and is fixedly connected to the top of the motor 17.

[0033] In specific implementation, based on the above implementation, the cylinder 28 is activated, causing the drive end of the cylinder 28 to extend and drive the motor 17 and the drill bit 18 to move downward. During this process, the motor 17 needs to be activated at the same time, so that the drill bit 18 can rotate and move downward at the same time, which facilitates the drilling operation on the mining tools below.

[0034] It also includes a lubrication assembly, which includes a water tank 19 containing clean water. The water tank 19 is fixedly installed on the rear side of the drilling table 1. A hose 20 is fixedly inserted into the bottom of one side of the water tank 19. A water spray head 21 is provided on the side of the motor 17 away from the drive end. The water spray head 21 is inclined and faces the bottom end of the drill bit 18. The other end of the hose 20 is fixedly inserted into the water spray head 21.

[0035] In practice, based on the above implementation, the water spray head 21 is turned on so that the water spray head 21 sprays clean water from the water tank 19 onto the drilling position. This not only cools the position but also lubricates it, which helps to extend the service life of the drilling tool 18.

[0036] It should be noted that since the hose 20 is fixedly installed at the bottom of one side of the water tank 19, the water pressure will force the clean water into the spray head 21. At this time, the spray head 21 can be turned on to spray the clean water. Also, since the spray head 21 is tilted and faces the drive end of the motor 17, the clean water will be sprayed accurately at the drilling position, which can lubricate the drilling part of the mining tool and cool the drill bit 18.

[0037] See Figure 1-5 It also includes a water circulation component, which includes a circulation pipe 22. One end of the circulation pipe 22 is fixedly inserted into the bottom of the rear side of the drilling table 1 and is connected to the receiving trough 2. The other end of the circulation pipe 22 is fixedly inserted into the top of the rear side of the water storage tank 19. A water pump 23 is installed on the circulation pipe 22.

[0038] In practice, based on the above implementation, by turning on the water pump 23, the water resources filtered in the receiving tank 2 can be re-injected into the water storage tank 19 through the circulation pipe 22, thereby achieving the effect of water resource recycling and saving processing costs.

[0039] See Figure 1-5 A gap is left between the first filter screen 3 and the second filter screen 4, and a support spring 24 and a telescopic rod 27 are provided. A contact block 25 and an electromagnetic button 26 are also provided between the first filter screen 3 and the second filter screen 4. The contact block 25 and the electromagnetic button 26 cooperate to abut against each other, and the electromagnetic button 26 is electrically connected to the electric push rod 5.

[0040] In specific implementation, based on the above implementation, when metal impurities continuously fall on the top of the second filter screen 4, downward pressure can be generated. When the second filter screen 4 drives the contact block 25 to abut against the electromagnetic button 26, the electromagnetic button 26 can send an electrical signal to the electric push rod 5 through the circuit, so that the electric push rod 5 automatically opens and extends the drive end to the set distance, so that the first filter screen 3 and the second filter screen 4 rotate at a fixed angle, thereby realizing adaptive automatic cleaning of metal impurities on the top of the second filter screen 4, which can further improve the cleaning effect.

[0041] It should be noted that programming technology needs to be embedded in the electromagnetic button 26 to control the time and interval of opening the electromagnetic button 26, thereby facilitating the control of the distance of the electric push rod 5. Since the technology of embedding programming technology in the electromagnetic button 26 is a well-known existing technology, it will not be elaborated on further.

[0042] Furthermore, for the electromagnetic button 26, we preferably use the LA38 series model electromagnetic button 26. This electromagnetic button 26 supports emergency stop and self-reset functions, can be programmed, and is suitable for industrial control scenarios. We can also cover the electromagnetic button 26 with a waterproof membrane to prevent sewage from seeping into the electromagnetic button 26, thereby helping to extend the service life of the electromagnetic button 26. Since the electromagnetic button 26 is existing technology and is not a problem that needs to be solved in the background technology of this specification, we will not elaborate on it further.

[0043] See Figure 1-5 There are six support springs 24, and the number of telescopic rods 27 corresponds to the number of support springs 24. The six support springs 24 and the telescopic rods 27 are fixedly installed at equal intervals at both ends between the first filter screen 3 and the second filter screen 4. The arrangement of the six support springs 24 and the telescopic rods 27 can ensure that both ends of the second filter screen 4 are subjected to balanced forces, avoiding the problem of the second filter screen 4 tilting.

[0044] Working principle: Before use, all electrical components involved in the drilling device need to be connected to an external power source, or a battery pack should be installed on the outside of the drilling table 1 in an area that does not obstruct other components. Then, the battery pack is connected to the electrical components through a circuit to provide power to the electrical components, thereby ensuring their normal operation. Since connecting the electrical components to an external power source or setting up a battery pack for power supply is existing technology and is not a problem that needs to be solved in the background technology of this manual, it will not be explained in detail. It should also be noted that before using the drilling device, we need to check whether there are any abnormalities in the components of the device.

[0045] In use, two symmetrical grippers can be set on the top of the drilling table 1. The two grippers are located on both sides of the receiving trough 2. The mining tool to be drilled is positioned on the grippers. Then, the cylinder 28 is turned on, so that the driving end of the cylinder 28 extends and drives the motor 17 and the drilling cutter 18 to move downward. During this process, the motor 17 needs to be turned on at the same time so that the drilling cutter 18 can rotate and move downward at the same time, which is convenient for drilling the mining tool below.

[0046] During the above operation, the water spray head 21 needs to be turned on so that the water spray head 21 sprays clean water from the water tank 19 onto the drilling position. This not only cools the position but also lubricates it, which helps to extend the service life of the drilling tool 18.

[0047] After cooling, the wastewater and metal debris fall into the receiving trough 2 together. At this time, the cooperation of the first filter screen 3 and the second filter screen 4 can separate the solid and liquid. When there are too many metal impurities on the top of the second filter screen 4, the electric push rod 5 is turned on, which can extend the drive end of the electric push rod 5, so that the first filter screen 3 drives the second filter screen 4 to rotate around the rotating shaft 8 until one end of the first filter screen 3 abuts against the first limiting member 11. At this time, the impurities will slide into the slag hopper 13 along the inclined second filter screen 4. This achieves the effect of electric cleaning of metal impurities from the second filter screen 4, reducing the workload of personnel and avoiding the safety hazard of metal impurities directly contacting personnel's hands and causing scratches.

[0048] During the above operation, when metal impurities continuously fall onto the top of the second filter screen 4, downward pressure is generated. When the second filter screen 4 drives the contact block 25 to abut against the electromagnetic button 26, the electromagnetic button 26 can send an electrical signal to the electric push rod 5 through the circuit, causing the electric push rod 5 to open automatically and extend the drive end to the set distance, so that the first filter screen 3 and the second filter screen 4 rotate at a fixed angle, realizing adaptive automatic cleaning of metal impurities on the top of the second filter screen 4, which can further improve the cleaning effect.

[0049] Finally, when the slag receiving hopper 13 is almost full of metallic impurities, pull the slag receiving hopper 13 to pull it out from the cleaning port 14, making it convenient for personnel to recover and process the impurities collected in the slag receiving hopper 13.

[0050] By turning on the water pump 23, the filtered water in the receiving tank 2 can be re-injected into the water storage tank 19 through the circulation pipe 22, thus achieving the effect of water resource recycling and saving processing costs.

[0051] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
