[0024] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0026] like Figure 1-3 As shown, this application provides a slag removal device for coal mines, including a mounting plate 1, which is a flat iron plate. A lead screw 37 is connected to the mounting plate 1 in the left and right directions by bearings. A drive unit 12 is fixedly installed on the right side of the mounting plate 1. The drive unit 12 is a servo motor. The output end of the drive unit 12 is coaxially fixed with the right end of the lead screw 37.

[0027] Two sets of guide rails are fixedly installed on both sides of the lead screw 37 on the mounting plate 1. Multiple sets of sliders are slidably connected on the guide rails. A housing 2 is fixedly installed on the slider. A nut 38 is fixedly installed on the lower side of the housing 2. The nut 38 is threadedly connected to the lead screw 37.

[0028] A PLC control system (not shown in the figure) is fixedly installed on the housing 2. The PLC control system is used to control various electrical components.

[0029] The drive unit 12 is connected to the PLC control system. When the drive unit 12 is powered on, the lead screw 37 rotates and drives the housing 2 to slide in the left and right directions through the cooperation with the nut 38.

[0030] The container 2 has a liquid storage tank 36 and a separation tank 17. The liquid storage tank 36 is used to store liquid media, which is used to assist drilling. The separation tank 17 is used to collect coal slag and by-products.

[0031] The separation chamber 17 has a slag discharge port 3 and a core extraction port 4 on both sides. The inner bearing of the separation chamber 17 is connected to a tilting plate 6. The right side of the box 2 is fixedly installed with a drive unit 2 13, which is a servo motor. The drive unit 2 13 is connected to the PLC control system signal. The output end of the drive unit 2 13 is fixedly connected to one side of the tilting plate 6.

[0032] By controlling the rotation of the drive unit 2 13, the tilting plate 6 can be tilted, so that the falling slag can selectively slide down the slag discharge port 3 or the core sampling port 4.

[0033] A water pump 11 is fixedly installed on the housing 2. The water pump 11 is connected to the PLC control system. The power of the water pump 11 can be controlled by the PLC control system. The water inlet of the water pump 11 is connected to the pipeline of the liquid storage tank 36. When the water pump 11 is started, it can extract the liquid medium in the liquid storage tank 36.

[0034] A rotary joint 7 is connected to the upper pipeline of the separation chamber 17. A drill rod 8 is fixedly installed on the left side of the rotary joint 7. The rotary joint 7 ensures that the drill rod 8 will not affect the pipeline connecting the rotary joint 7 to the separation chamber 17 when it rotates. A drill bit 9 is fixedly installed at the end of the drill rod 8 away from the rotary joint 7. Multiple sets of through holes are opened in the circumferential direction on the side of the drill rod 8 near the drill bit 9.

[0035] After the drill bit 9 drills down the slag, it can be transported to the separation chamber 17 through multiple sets of through holes on the drill rod 8, via the internal pipeline of the drill rod 8 and the rotary joint 7.

[0036] The drive unit 3 14 is fixedly installed on the housing 2. The drive unit 3 14 is an AC asynchronous motor. The drive unit 3 14 is connected to the PLC control system signal. The output end of the drive unit 3 14 is connected to the drill rod 8 through gear meshing. When the drive unit 3 14 is powered on and started, it drives the drill rod 8 and the drill bit 9 to rotate through gear transmission, thereby realizing the drilling and core sampling of coal mine.

[0037] A plug 10 is movably connected to the outside of the drill rod 8. The plug 10 has a conical structure. Its function is to insert the small end into the groove that has been chiseled, and fix it to the wall through the large end of the plug 10. A sealing gasket is installed on the contact surface with the wall, so that the drill bit 9 is in a sealed state when it is working, preventing the liquid medium from flowing out and the gas from escaping.

[0038] The end of the plugger 10 away from the drill bit 9 is provided with an inlet pipe 16, and the end of the plugger 10 near the drill bit 9 is provided with multiple sets of outlet ports 15. The inlet pipe 16 is connected to the outlet ports 15 and the inlet pipe 16 is connected to the outlet of the water pump 11.

[0039] The liquid medium in the storage tank 36 is extracted by the water pump 11, and sprayed out from the outlet 15 through the inlet pipe 16. The flowing liquid medium drives the coal slag drilled by the drill bit 9 to enter through the through hole of the drill rod 8, and flows into the separation tank 17 through the internal pipeline of the drill rod 8.

[0040] Multiple sets of holes are opened on the tilting plate 6. When the slag falls from above the separation chamber 17 onto the tilting plate 6, it slides on the tilting plate 6 toward the slag discharge port 3 or the core sampling port 4. The liquid medium and mud water will leak from the holes on the tilting plate 6 to the bottom of the separation chamber 17. A drain port 5 is fixedly installed on one side of the bottom of the separation chamber 17, which can discharge or recycle the separated liquid. A suction pipe is connected to the top of the separation chamber 17. The suction pipe is connected to a fan, which can draw away the precipitated gas to prevent it from escaping.

[0041] like Figure 3-5As shown, in order to realize the automation function of fixed-point coring in coal mines, a control component is installed on the plugging device 10. The control component includes a control box 18 fixedly installed on one side of the inlet pipe 16. A control compartment is opened inside the control box 18 and is connected to the inside of the inlet pipe 16. A pressure plate 22 is slidably connected to the inside of the control compartment. An elastic part 25 is fixedly installed on the upper end of the pressure plate 22. A cylinder 19 is fixedly installed on the upper end of the control box 18. The cylinder 19 is connected to the PLC control system. A lifting plate 20 is fixedly installed on the movable end of the cylinder 19. The lifting plate 20 is located above the pressure plate 22 and is slidably connected to the control compartment. A distance sensor 28 is fixedly installed on the side of the lifting plate 20 near the pressure plate 22. The distance sensor 28 is connected to the PLC control system.

[0042] The cylinder 19 is initially in the extended state, so the lifting plate 20 is in the middle of the control compartment. The upper end of the elastic part 25 abuts against the lower end of the lifting plate 20. When the water pump 11 draws liquid medium and delivers it to the inlet pipe 16, the liquid pressure in the inlet pipe 16 will push the pressure plate 22 to slide upward against the elastic force of the elastic part 25 through the pipeline connected to the control compartment. The position of the pressure plate 22 is monitored by the distance sensor 28, thereby obtaining the pressure at the inlet pipe 16, which facilitates the adjustment of the power of the water pump 11 to meet the basic pressure requirements of slag conveying.

[0043] A slide groove is provided on one side of the control cabin, and a resistor strip 21 is slidably connected in the slide groove. The upper end of the resistor strip 21 is fixedly connected to the lifting plate 20. A contact block 24 is installed on one side of the pressure plate 22. The contact block 24 is electrically connected to the drive unit 12. The lower end of the resistor strip 21 is electrically connected to the PLC control system.

[0044] When a slight blockage occurs during the delivery process, the pressure inside the inlet pipe 16 increases, causing the pressure plate 22 to slide upward. The distance between the contact block 24 and the lower end of the resistor bar 21 increases, resulting in greater resistance. This reduces the operating speed of the drive unit 12, thereby slowing down the feed speed of the drill bit 9 and reducing the risk of complete blockage. Once the delivery pipeline is cleared, the pressure inside the inlet pipe 16 decreases, and the pressure plate 22 slides downward under the elastic force of the elastic part 25, thereby increasing the feed speed of the drill bit 9 and improving mining efficiency.

[0045] A temporary storage compartment 26 is provided on the upper side of the control box 18, and a piston compartment 32 is provided on the lower side of the control box 18. The upper side of the control compartment is connected to the lower side of the piston compartment 32 by a pipeline. A reversible throttle valve 27 is connected to the pipeline connecting the control compartment and the piston compartment 32. The reversible throttle valve 27 is connected to the PLC control system signal. The other end of the reversible throttle valve 27 is connected to the pipeline of the temporary storage compartment 26. A piston rod 33 is slidably connected to the inner side of the piston compartment 32. An elastic part 34 is installed between the piston rod 33 and the upper end of the piston compartment 32. A contact sensor 35 is fixedly installed at the lower end of the piston compartment 32. The contact sensor 35 is connected to the PLC control system signal. Hydraulic oil is provided above the control compartment.

[0046] The reversible throttle valve 27 is initially in a throttling state towards the temporary storage chamber 26. Before drilling begins, the starting point and ending point of the core sampling need to be set in the PLC control system, i.e., the number of rotations of the drive unit 12. When the drill bit 9 is fed to the core sampling starting point position, the PLC control system will give the cylinder 19 a signal to retract. At this time, the lifting plate 20 slides upward with the moving end of the cylinder 19, causing the resistor bar 21 to completely disengage from the contact block 24. The drive unit 12 is de-energized and stops rotating, and the drill bit 9 no longer continues to feed forward.

[0047] The lifting plate 20 will squeeze the oil above the control chamber through the pipeline to the temporary storage chamber 26 and the piston chamber 32. Due to the throttling effect of the reversible throttle valve 27, most of the oil will flow into the piston chamber 32 first, causing the piston rod 33 to slide upward against the elastic force of the elastic part 34. The bottom of the piston rod 33 will separate from the contact sensor 2 35. After the cylinder 19 completes the retraction action, the pipeline pressure between the control chamber and the piston chamber 32 will decrease. Under the elastic force of the elastic part 34, the piston rod 33 will slowly push the oil into the temporary storage chamber 26. When the piston rod 33 contacts the contact sensor 2 35 again, the contact sensor 2 35 will give the PLC control system a signal to extend the cylinder 19, so that the contact block 24 on the pressure plate 22 contacts the resistor strip 21 again. The drive part 1 12 is energized and continues to drive the drill bit 9 to feed for coring. In this way, the pipeline is cleaned for a period of time before coring to ensure the accuracy of fixed-point coring and reduce the impact of residual slag in the pipeline on the analysis results.

[0048] To prevent the contact block 24 from separating from the resistor strip 21, the liquid medium will enter the upper part of the pressure plate 22 through the slide groove. A sealing strip can be fixed at the lower end of the resistor strip 21, passing through the bottom of the control box 18, and the sealing strip will block the gap of the slide groove when the resistor strip 21 slides upward.

[0049] When the drill bit 9 is fed to the end position of the core sampling, the cylinder 19 receives a signal from the PLC control system again and retracts, repeating the cleaning action of the delivery pipeline to ensure the integrity of the core sampling and avoid residue in the delivery pipeline. In addition, before the start, when the second signal from the contact sensor 2 35 is received, the drive unit 12 will automatically cut off the power or rotate in the reverse direction to exit the action.

[0050] A lifting plate 23 is slidably connected inside the control cabin. The lifting plate 23 is above the lifting plate 20. Two push rods are provided at the lower end of the lifting plate 23. The push rods pass through the lifting plate 20. A contact sensor 29 is fixedly installed at the upper end of the lifting plate 20. The contact sensor 29 is connected to the PLC control system signal.

[0051] A block 30 is slidably connected to one side of the control box 18. An elastic part 31 is fixedly installed on one side of the block 30. The lifting plate 20 is adapted to press the block 30 into the control box 18 when the cylinder 19 is extended, thereby blocking the connecting pipe between the control compartment and the piston compartment 32. After the pressure of the lifting plate 20 is lost, the block 30 is adapted to slide towards the control compartment by the elastic force of the elastic part 31, so that the control compartment and the piston compartment 32 are connected.

[0052] During the feed of drill bit 9, when the delivery pipeline is completely blocked, the pressure in the inlet pipe 16 will suddenly increase. Pressure plate 22 will overcome the elastic force of elastic part 25 and slide upwards under the pressure of the liquid medium. After contacting the push rod at the lower end of lifting plate 23, it will push lifting plate 23 upwards. At this time, the position of lifting plate 20 under the action of cylinder 19 does not change. The pipeline between control chamber and piston chamber 32 is blocked by block 30. When lifting plate 23 disengages from contact sensor 29, contact sensor 29 will send a signal to drive part 12 and reversible throttle valve 27 via PLC control system to reverse the direction. At this time, lifting plate 23 slides upwards... The oil in the pressure control chamber quickly enters the temporary storage chamber 26. The drive unit 12 rotates slowly in the opposite direction, causing the drill bit 9 to withdraw from the feed, increasing the gap in the borehole, thereby clearing the blockage of slag. The reverse reversible throttle valve 27 will limit the descent speed of the lifting plate 23 to ensure complete clearing. After the delivery pipeline is cleared, the lifting plate 23 slowly falls back to the contact position with the contact sensor 29 under the pressure of the oil. When the lifting plate 23 contacts the contact sensor 29 again, the contact sensor 29 will send a signal to the drive unit 12 and the reversible throttle valve 27 to switch directions through the PLC control system. The drill bit 9 will resume its feed action to ensure the smooth operation of the core sampling.

[0053] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
