[0011] Preferably, the side, where the pressing block can abut against the convex block, is a slope which is matched with the rotating direction of the rotating disc.

[0012] Compared with the prior art, the utility model has at least the following beneficial effects:

[0013] In the above scheme, by setting the starting mechanism, when the starting motor makes the main gear drive the drill bit on the rotating shaft to work, the main gear will simultaneously drive the transmission gear meshing with the main gear to rotate, thereby driving the rotating disc at the top of the transmission gear to rotate, which will rotate faster and faster with the rotation speed of the main gear, thereby making the protrusion inside the groove on the rotating disc be turned out by the centrifugal force, and the protrusion will be in contact with the inclined surface of the pressing block during rotation, making the pressing block move inside the sliding slot one, and the movement of the pressing block makes the pressing switch be pressed, and after the pressing switch is pressed, the cooling mechanism will be controlled to work to cool the drill bit, and when the motor is turned off, the spring one will reset to collect the protrusion inside the groove, so that it is no longer in contact with the pressing block, and the pressing block will be reset under the action of the spring two, and will no longer press the pressing switch, so that the cooling mechanism is stopped synchronously. The advantage of this is that the main gear drives the drill bit on the rotating shaft to work at the same time, and the rotation of the transmission gear makes the rotating disc rotate, and the centrifugal force controls the protrusion to press the pressing block to press the pressing switch, so that the cooling mechanism can work at the same time as the motor, which is convenient for cooling the drill bit in time, and the cooling mechanism will also stop synchronously when the motor is turned off, which ensures the cooling time and effect.

[0014] By setting the cooling mechanism, when the pressing switch is pressed, the water pump will draw water or coolant from the water tank through the water outlet pipe one, and then deliver the water or coolant into the inside of the protective shell through the water outlet pipe two. The water or coolant enters the cavity between the waterproof plate and the moving plate, then enters the spray pipe from the top of the spray pipe, and finally sprays out from the nozzle to cool the drill bit, preventing the high temperature generated by the long-time rotation of the drill bit from affecting the service life of the drill bit.

[0015] By setting the adjusting mechanism, when it is necessary to adjust the moving plate to move the height of the drill bit, press the disc from the outside of the shell to make the rotating rod move inside the shell. When the rotating rod moves, it will drive the gear two to move, and after the gear two moves, it will mesh with the gear one. Since the gear one on the fixed frame in the middle of the rotating rod will rotate with the meshing main gear when the motor starts, when the gear two moves to mesh with the gear one, the gear two will rotate, driving the rotating rod to rotate. When the rotating rod rotates, it will drive the gear one on the fixed frame on both sides of the rotating rod to rotate, thereby driving the gear three meshing with the gear one on the fixed frame on both sides of the rotating rod to rotate. The gear three will drive the moving plate to move on the screw rod when rotating, and the rotating rod will slide inside the sliding slot two when the moving plate moves. The advantage of this is that it does not need to set too many motors, and one motor can drive the drill bit while driving the rotating rod to rotate through the gear one meshing with the main gear, thereby driving the gear three on the fixed frame on both sides of the rotating rod to rotate, so that it drives the moving plate to move on the screw rod when rotating, which ensures the implementation effect while saving funds.

[0016] By setting a locking block, when it is not necessary to adjust the shift plate to move the drill bit's height, rotate the locking block on the outside of the housing until it contacts the disc. By moving the disc, the rotating rod is pushed outward. As the rotating rod moves, it drives gear two to move, causing it to disengage from gear one, thus stopping the shift plate and placing it in the appropriate position. When it is necessary to adjust the shift plate, press the disc from the outside of the housing to re-engage gear two with gear one for adjustment. The setup is simple and the use is convenient.

Detailed Implementation

[0028] The following is a detailed description of a cooling device for a coal mine drilling rig provided by this utility model, with reference to the accompanying drawings and specific embodiments. It should be noted that, to make the embodiments more detailed, the following embodiments are the best and preferred embodiments; those skilled in the art can also use other alternative methods to implement some known technologies; and the accompanying drawings are only for more specific description of the embodiments and are not intended to specifically limit this utility model.

[0029] like Figures 1-5 and Figure 7 As shown, an embodiment of this utility model provides a cooling device for a coal mine drilling rig, including a housing 1. A moving plate 2 is provided inside the housing 1. A rotating mechanism 3 and a cooling mechanism 6 are installed on the moving plate 2. The rotating mechanism 3 includes a drive gear 31 rotatably connected to the top of the moving plate 2. A motor 32 is fixedly connected to the top of the drive gear 31. A rotating shaft 35 is fixedly connected to the bottom of the drive gear 31. The rotating shaft 35 passes through the moving plate 2 and is fixedly connected to a drill bit 33. A protective shell 34 is fixedly connected to the bottom of the moving plate 2 to protect the drill bit 33. A push switch 13 that can control the cooling mechanism 6 is fixedly connected to one inner wall of the housing 1 above the moving plate 2. A transmission gear 9 that is rotatably connected to the top of the moving plate 2 is meshed on the side of the drive gear 31 near the push switch 13. An activation mechanism 4 that can be pressed to the push switch 13 is installed on the top of the transmission gear 9.

[0030] The starting mechanism 4 includes a turntable 41 fixedly connected to the top of the transmission gear 9. Several grooves 42 are provided on the side wall of the turntable 41. A protrusion 43 is slidably connected inside the groove 42. A spring 44 is fixedly connected to one inner wall of the groove 42. The end of the spring 44 away from the inner wall of the groove 42 is fixedly connected to the protrusion 43. A sliding groove 10 is provided on the top of the sliding plate 2 below the push switch 13. A pressing block 11 is slidably connected inside the sliding groove 10. One side of the pressing block 11 abuts against the push switch 13. Several springs 12 are fixedly connected between the side of the pressing block 11 that abuts against the push switch 13 and the inner wall of the housing 1. The side of the pressing block 11 away from the push switch 13 can abut against the protrusion 43.

[0031] The cooling mechanism 6 includes a water tank 61 fixedly connected to the top of the shift plate 2. A first water outlet pipe 62, communicating with the interior of the water tank 61, is fixedly connected to the water tank 61. A water pump 63, communicating with the first water outlet pipe 62, is fixedly connected to the end of the first water outlet pipe 62 away from the water tank 61. A second water outlet pipe 64, communicating with the water pump 63, is fixedly connected to the outlet of the water pump 63. The end of the second water outlet pipe 64 away from the water pump 63 passes through the shift plate 2 and then through one side of the protective shell 34, communicating with the interior of the protective shell 34. The inner wall of the protective shell 34 is connected to the second water outlet pipe 64. Two opposing nozzles 65 are fixedly connected to the bottom of 4. Several nozzles 66 are fixedly connected to the opposite side of each nozzle 65. The top of the nozzle 65 is connected to the outside, and the bottom of the nozzle 65 is sealed. A waterproof plate 67 flush with the top of the nozzle 65 is fixedly connected between the tops of the nozzles 65. The waterproof plate 67 and the bottom of the moving plate 2 form a cavity. The water outlet pipe 64 is connected to the cavity. The rotating shaft 35 passes through the waterproof plate 67. The side of the pressing block 11 that can abut against the protrusion 43 is an inclined surface that matches the rotation direction of the turntable 41.

[0032] By setting the starting mechanism 4, when the starting motor 32 causes the drive gear 31 to drive the drill bit 33 on the rotating shaft 35 to rotate, the drive gear 31 will simultaneously drive the transmission gear 9 meshing with the drive gear 31 to rotate, thereby driving the turntable 41 on the top of the transmission gear 9 to rotate. As the turntable 41 rotates, it will increase in speed with the rotation speed of the drive gear 31, causing the protrusion 43 inside the groove 42 on the turntable 41 to be rotated out by centrifugal force. The protrusion 43 will abut against the inclined surface of the pressing block 11 during rotation, causing the pressing block 11 to move inside the slide groove 10. The movement of the pressing block 11 will press the pressing switch 13. After the pressing switch 13 is pressed, it will control the cooling mechanism 6 to work to cool the drill bit 33. When the motor 32 is turned off, the spring 44 will reset and retract the protrusion 43 into the groove 42, so that it no longer abuts against the pressing block 11. The pressing block 11 will reset under the action of the spring 12, and will no longer press the pressing switch 13, so that the cooling mechanism 6 will stop synchronously. The advantage of this is that while the drive gear 31 drives the drill bit 33 on the rotating shaft 35 to rotate, the rotation of the transmission gear 9 will also make the turntable 41 rotate. The centrifugal force will control the protrusion 43 to press the pressing block 11 to press the pressing switch 13, so that the cooling mechanism 6 can start working at the same time as the motor 32, which facilitates timely cooling of the drill bit 33. When the motor 32 is turned off, the cooling mechanism 6 will also stop synchronously, ensuring the cooling time and effect.

[0033] By setting up a cooling mechanism 6, when the push switch 13 is pressed, the water pump 63 will draw water or coolant from the water tank 61 through the first water outlet pipe 62, and then deliver the water or coolant into the interior of the protective shell 34 through the second water outlet pipe 64. After entering the interior of the protective shell 34, the water or coolant will reach the cavity between the waterproof plate 67 and the moving plate 2, and then enter the nozzle 65 from the top of the nozzle 65, and finally spray out from the nozzle 66 to cool the drill bit 33, preventing the high temperature generated by the drill bit 33 during long-term rotation from affecting the life of the drill bit 33.

[0034] like Figures 1-4 and Figure 6 As shown, gears 3 and 7 are rotatably connected to the top of the moving plate 2 on both sides of the driving gear 31. Gears 3 and 7 do not mesh with the driving gear 31. A screw 8 is provided on gear 3 and 7 and threadedly connected to it. The two ends of the screw 8 are fixedly connected to the top and bottom of the housing 1, respectively. Two fixing posts 14 for limiting the movement direction of the moving plate 2 are also fixedly connected between the top and bottom of the housing 1. The top of the moving plate 2 is provided with an adjustment mechanism 5 that can cooperate with gears 3 and 7 to adjust the height of the moving plate 2. The adjustment mechanism 5 includes a rotating rod 51 that penetrates the housing 1. Three "L"-shaped fixing frames 52 are sleeved on the rotating rod 51. A gear 2 55 is provided in the middle of the fixing frame 52 and fixedly connected to the outer surface of the rotating rod 51. One end of frame 52 is slidably connected to the top of sliding plate 2. The other end of fixed frame 52 is rotatably connected to gear 53, which can mesh with gear 2 55. Gear 1 53 on fixed frame 52 in the middle of rotating rod 51 meshes with driving gear 31. Gear 1 53 on fixed frames 52 on both sides of rotating rod 51 meshes with gear 3 7 on both sides of driving gear 31 respectively. Both ends of rotating rod 51 are fixedly connected to disc 54. Slide groove 2 15 is provided on both opposite sides of housing 1. One end of rotating rod 51 passes through housing 1 through slide groove 2 15 and extends a distance. On the side of housing 1 where slide groove 2 15 is provided, an "L"-shaped clip 16 is rotatably connected. Clip 16 can abut against disc 54 to separate rotating rod 51 from the inside of housing 1.

[0035] By setting the adjustment mechanism 5, when it is necessary to adjust the height of the drill bit 33 by adjusting the moving plate 2, the disc 54 is pressed from the outside of the housing 1, causing the rotating rod 51 to move inside the housing 1. When the rotating rod 51 moves, it will drive the second gear 55 to move. After the second gear 55 moves, it will mesh with the first gear 53. Since the first gear 53 on the fixed frame 52 in the middle of the rotating rod 51 will rotate together with the meshing drive gear 31 when the motor 32 starts, the second gear 55 will rotate after it moves to mesh with the first gear 53, driving the rotating rod 51 to rotate. When the rotating rod 51 rotates, it will drive the first gear 53 on the fixed frames 52 on both sides of the rotating rod 51 to rotate. This, in turn, drives the gear 7, which meshes with the gear 1 53 on the fixed frame 52 on both sides of the rotating rod 51, to rotate. When the gear 7 rotates, it drives the moving plate 2 to move on the screw 8. When the moving plate 2 moves, the rotating rod 51 will slide inside the slide groove 2 15. The advantage of this is that it does not require too many motors 32. Using one motor 32 to drive the drill bit 33, the rotating rod 51 is driven to rotate through the gear 1 53 meshing with the drive gear 31. This causes the gear 1 53 on the fixed frame 52 on both sides of the rotating rod 51 to drive the gear 7 to rotate, which in turn drives the moving plate 2 to move on the screw 8. This ensures the desired effect while saving costs.

[0036] By setting the latch 16, when it is not necessary to adjust the height of the drill bit 33 by adjusting the shift plate 2, the latch 16 is rotated on the outside of the housing 1 so that the latch 16 abuts against the disc 54. By moving the position of the disc 54, the rotating rod 51 is pushed outward. When the rotating rod 51 moves, it will drive the gear 2 55 to move, so that it is no longer engaged with the gear 1 53, thus stopping the shift plate 2 from moving and placing it in the appropriate position. When it is necessary to adjust the shift plate 2, the disc 54 is pressed from the outside of the housing 1, so that the gear 2 55 can re-engage with the gear 1 53 for adjustment. The setup is simple and the use is convenient.

[0037] The technical solution provided by this utility model, by setting up a starting mechanism 4, when the starting motor 32 causes the drive gear 31 to drive the drill bit 33 on the rotating shaft 35 to rotate, the drive gear 31 will simultaneously drive the transmission gear 9 meshing with the drive gear 31 to rotate, thereby driving the turntable 41 on the top of the transmission gear 9 to rotate. As the turntable 41 rotates, it will increase in speed with the rotation speed of the drive gear 31, thereby causing the protrusion 43 inside the groove 42 on the turntable 41 to be rotated out by centrifugal force. The protrusion 43 will abut against the inclined surface of the pressing block 11 during the rotation, causing the pressing block 11 to move inside the slide groove 10. The movement of the pressing block 11 will press the pressing switch 13, and after the pressing switch 13 is pressed, it will control the cooling mechanism 6 to work. The drill bit 33 is cooled. When the motor 32 is turned off, the spring 44 will reset and retract the protrusion 43 into the groove 42, so that it no longer abuts against the pressing block 11. The pressing block 11 will reset under the action of the spring 12, and will no longer press the pressing switch 13, so that the cooling mechanism 6 stops synchronously. The advantage of this is that while the drive gear 31 drives the drill bit 33 on the rotating shaft 35 to rotate, the rotation of the transmission gear 9 can also make the turntable 41 rotate. The centrifugal force will control the protrusion 43 to press the pressing block 11 to press the pressing switch 13, so that the cooling mechanism 6 can start working at the same time as the motor 32, which facilitates timely cooling of the drill bit 33. When the motor 32 is turned off, the cooling mechanism 6 will also stop synchronously, ensuring the cooling time and effect.

[0038] By setting up a cooling mechanism 6, when the push switch 13 is pressed, the water pump 63 will draw water or coolant from the water tank 61 through the first water outlet pipe 62, and then deliver the water or coolant into the interior of the protective shell 34 through the second water outlet pipe 64. After entering the interior of the protective shell 34, the water or coolant will reach the cavity between the waterproof plate 67 and the moving plate 2, and then enter the nozzle 65 from the top of the nozzle 65, and finally spray out from the nozzle 66 to cool the drill bit 33, preventing the high temperature generated by the drill bit 33 during long-term rotation from affecting the life of the drill bit 33.

[0039] By setting the adjustment mechanism 5, when it is necessary to adjust the height of the drill bit 33 by adjusting the moving plate 2, the disc 54 is pressed from the outside of the housing 1, causing the rotating rod 51 to move inside the housing 1. When the rotating rod 51 moves, it will drive the second gear 55 to move. After the second gear 55 moves, it will mesh with the first gear 53. Since the first gear 53 on the fixed frame 52 in the middle of the rotating rod 51 will rotate together with the meshing drive gear 31 when the motor 32 starts, the second gear 55 will rotate after it moves to mesh with the first gear 53, driving the rotating rod 51 to rotate. When the rotating rod 51 rotates, it will drive the first gear 53 on the fixed frames 52 on both sides of the rotating rod 51 to rotate. This, in turn, drives the gear 7, which meshes with the gear 1 53 on the fixed frame 52 on both sides of the rotating rod 51, to rotate. When the gear 7 rotates, it drives the moving plate 2 to move on the screw 8. When the moving plate 2 moves, the rotating rod 51 will slide inside the slide groove 2 15. The advantage of this is that it does not require too many motors 32. Using one motor 32 to drive the drill bit 33, the rotating rod 51 is driven to rotate through the gear 1 53 meshing with the drive gear 31. This causes the gear 1 53 on the fixed frame 52 on both sides of the rotating rod 51 to drive the gear 7 to rotate, which in turn drives the moving plate 2 to move on the screw 8. This ensures the desired effect while saving costs.

[0040] By setting the latch 16, when it is not necessary to adjust the height of the drill bit 33 by adjusting the shift plate 2, the latch 16 is rotated on the outside of the housing 1 so that the latch 16 abuts against the disc 54. By moving the position of the disc 54, the rotating rod 51 is pushed outward. When the rotating rod 51 moves, it will drive the gear 2 55 to move, so that it is no longer engaged with the gear 1 53, thus stopping the shift plate 2 from moving and placing it in the appropriate position. When it is necessary to adjust the shift plate 2, the disc 54 is pressed from the outside of the housing 1, so that the gear 2 55 can re-engage with the gear 1 53 for adjustment. The setup is simple and the use is convenient.
