The above patent has the following shortcomings: the existing hydraulic anchor drill cannot protect the operator during use. When mining coal, the high-speed rotating drill contacts the coal, which can easily cause the coal to splash onto the operator or other machinery and equipment, causing damage to the operator and machinery and other equipment, and reducing the efficiency of coal mining. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that when the hydraulic anchor drill comes into contact with coal during use, coal is easily splashed onto the operator and the equipment, causing damage to the equipment, and to propose a directional hydraulic anchor drill for coal mining and a method of use.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A directional hydraulic anchor drill for coal mining, comprising a hydraulic rod and an anchor drill body fixedly arranged on the top of the hydraulic rod, the top of the hydraulic rod is fixedly connected to a mounting plate, and also comprises a transparent protective cover fixedly connected to the mounting plate, the inner wall of the transparent protective cover is slidably connected to two side scrapers and a lower scraper, and the tops of the two side scrapers are fixedly connected to a driving plate.

[0007] Preferably, the anchor drilling rig body comprises a motor fixedly mounted on the top of the mounting plate, and a drill bit and a planetary gear reducer are fixedly mounted on the output end of the motor.

[0008] Preferably, connecting rods are fixedly connected to both sides of the planetary gear reducer, and the two connecting rods are fixedly connected to the side scrapers respectively.

[0009] Preferably, a fixing plate is fixedly connected to the hydraulic rod, two telescopic guide rods are fixedly connected between the fixing plate and the mounting plate, an armrest is fixedly connected to the hydraulic rod, and a manipulation arm is rotatably connected to one side of the mounting plate.

[0010] Preferably, mounting plates are fixedly connected to both sides of the transparent protective cover, sealing cylinders are fixedly connected to the two mounting plates, piston plates are slidably connected inside the sealing cylinders, and a sliding rod is fixedly connected to the top of the piston plates.

[0011] Preferably, a trapezoidal plate corresponding to the driving plate is fixedly connected to the top of the sliding rod, the sliding rod is slidably connected to the sealing cylinder, a spring is sleeved on the sliding rod, and both ends of the spring are fixedly connected to the trapezoidal plate and the sealing cylinder respectively.

[0012] Preferably, fixing rods are fixedly connected to the outer walls of both sides of the transparent protective cover, and circular rings are fixedly connected to the outsides of the two fixing rods. A cavity is opened inside the circular ring, and a liquid inlet pipe is fixedly connected between the cavity of the circular ring and the sealing cylinder.

[0013] Preferably, a plurality of liquid spraying pipes are fixedly connected to the top of the cavity of the circular ring, and filter mesh holes are fixedly connected to the tops of the plurality of liquid spraying pipes, and a liquid suction pipe is fixedly connected to one side of the sealing cylinder.

[0014] Preferably, a plurality of water outlet holes are provided on the bottom wall of the transparent protective cover, and the bottoms of the plurality of water outlet holes are fixedly connected to a drainage pipe, and one end of the drainage pipe extends to the bottom of the mounting plate.

[0015] The present invention also provides a method for using a directional hydraulic anchor drill for coal mining, which is operated by the following steps: S1. At a place where coal mining is required, the position of the anchor drill body is adjusted, and the anchor drill body can be pushed forward by starting the hydraulic rod to drill a hole in the coal mine. While the coal mine is being drilled, the coal mine splashed outward can be shielded by a transparent protective cover; S2. The drill bit is driven to rotate by a motor to drill a hole in the coal mine. At the same time, the connecting rod and the side scraper can be driven to rotate by a planetary gear reducer. The side scraper drives the lower scraper to scrape off the coal mine particles and dust splashed on the side wall and bottom wall of the transparent protective cover, and the drill bit condition and the progress of coal mining are observed in time.

[0016] Compared with the prior art, the present invention provides a directional hydraulic anchor drill for coal mining, which has the following beneficial effects: 1. The directional hydraulic anchor drill for coal mining can effectively prevent the anchor drill from causing harm to the operator by stones and other particles splashing everywhere during the drilling process through a transparent protective cover, effectively preventing machines and other equipment from being smashed, and at the same time, the drilling progress and drilling conditions can be observed in time through the transparent protective cover. 2. The directional hydraulic anchor drill for coal mining can drive the drill bit to rotate through a motor, while the planetary gear reducer can drive the connecting rod to rotate, and the connecting rod drives the side scraper to rotate to scrape the dust adsorbed on the inner wall of the transparent protective cover, and the side scraper simultaneously drives the lower scraper to scrape the bottom wall of the transparent protective cover, so that the operator can observe the drilling conditions in time while being protected by the transparent protective cover. 3. The directional hydraulic anchor drill for coal mining drives the driving plate to rotate while the side scraper rotates. When the driving plate rotates to the trapezoidal plate, it contacts the inclined surface of the trapezoidal plate. Under the guidance of the slide bar, the trapezoidal plate drives the slide bar compression spring to slide downward, thereby pushing the piston plate to move downward. When the driving plate rotates to disengage from the trapezoidal plate, the spring resets the trapezoidal plate upward, and the trapezoidal plate drives the slide bar and the piston plate to automatically reset upward. The driving plate reciprocates and contacts the trapezoidal plate, so that the piston plate repeatedly performs piston motion in the sealing cylinder. When the piston plate repeatedly performs piston motion, the sealing cylinder repeatedly passes through The liquid suction pipe sucks water and enters the ring from the liquid inlet pipe. In this way, the water in the ring is sprayed out through multiple spray pipes. The water source passes through the filter mesh to turn the water flow into mist water, which is sprayed out to reduce dust around the drilling hole, effectively reducing the dust generated during the drilling process. At the same time, the water mist can also reduce the temperature between the drill bit and the coal mine, reduce the generation of sparks, and reduce the dust content in the air, which helps to protect the health of the workers. Then, the side scraper and the lower scraper are used to scrape the mixture of water and dust on the inner wall of the transparent protective cover in time, so that the operator can still observe the drilling situation in time. 4. The directional hydraulic anchor drilling rig for coal mining, while the anchor drilling rig continues to drill holes, when the water flows into the transparent protective cover, it can enter the drain pipe through the multiple water outlet holes at the bottom of the transparent protective cover and be automatically discharged, and will not accumulate in the transparent protective cover. At the same time, the lower scraper is used to repeatedly scrape the water outlet holes of the transparent protective cover to prevent the water outlet holes from being blocked.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0020] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] Example 1: Reference Figure 1-Figure 9 A directional hydraulic anchor drilling rig for coal mining includes a hydraulic rod 1 and an anchor drilling rig body 2 fixedly arranged on the top of the hydraulic rod 1, a mounting plate 3 is fixedly connected to the top of the hydraulic rod 1, and also includes a transparent protective cover 4 fixedly connected to the mounting plate 3, two side scrapers 5 and a lower scraper 6 are slidably connected to the inner wall of the transparent protective cover 4, and the tops of the two side scrapers 5 are fixedly connected to a driving plate 7.

[0022] In the present invention, when mining in a coal mine, the hydraulic rod 1 is used to push the anchor drill body 2 forward or backward to perform drilling operations. While drilling, particles splashed everywhere are shielded by the transparent protective cover 4, which can effectively prevent the splashed stones and other particles from causing harm to the operator during the drilling process, and effectively prevent the equipment from being damaged by the splashed objects. At the same time, the drilling situation can be observed in time through the transparent protective cover 4.

[0023] Example 2: Reference Figure 1-Figure 9 , which is basically the same as the first embodiment, further, the anchor drilling machine body 2 includes a motor 8 fixedly mounted on the top of the mounting plate 3, and a drill bit 9 and a planetary gear reducer 10 are fixedly mounted on the output end of the motor 8.

[0024] Connecting rods 11 are fixedly connected to both sides of the planetary gear reducer 10 , and the two connecting rods 11 are fixedly connected to the side scrapers 5 respectively.

[0025] In the present invention, the drill bit 9 is driven to rotate by the motor 8 to perform the drilling operation. Since the drill bit 9 rotates at a high speed during the drilling process, when the motor 8 is started, the connecting rod 11 can be driven to rotate slowly through the planetary gear reducer 10, thereby driving the side scrapers 5 on both sides to scrape and clean the dust splashed on the side walls of the transparent protective cover 4, so that the operator can check the progress of the drilling in time. When the side scrapers 5 rotate, the side scrapers 5 drive the lower scraper 6 at the bottom to clean the dust and particulate matter on the bottom wall of the transparent protective cover 4, so that the operator can observe the drilling situation in time.

[0026] A fixing plate 12 is fixedly connected to the hydraulic rod 1 , two telescopic guide rods 13 are fixedly connected between the fixing plate 12 and the mounting plate 3 , a handrail 14 is fixedly connected to the hydraulic rod 1 , and a manipulation arm 15 is rotatably connected to one side of the mounting plate 3 .

[0027] In the present invention, when the hydraulic rod 1 pushes the anchor drill body 2 forward to drill holes, the telescopic guide rod 13 can assist the anchor drill body 2 in horizontal drilling, so that the anchor drill body 2 can drill horizontally or vertically in one direction; the main function of the operating arm 15 is to adjust the angle and direction of the drill bit 9 to achieve directional drilling. By rotating the operating arm 15, the operator can accurately control the position of the drill bit 9 in three-dimensional space to adapt to different anchor drilling requirements, such as drilling at different positions and angles such as the roof and two sides of the coal mine tunnel.

[0028] Example 3: Reference Figure 1-Figure 8 , which is basically the same as the first embodiment, and further, mounting plates 16 are fixedly connected to both sides of the transparent protective cover 4, sealing cylinders 17 are fixedly connected to the two mounting plates 16, a piston plate 18 is slidably connected inside the sealing cylinder 17, and a sliding rod 19 is fixedly connected to the top of the piston plate 18.

[0029] In the present invention, the piston plate 18 slides up and down in the sealing tube 17 and can perform piston motion in the sealing tube 17. When the piston plate 18 is upward, a negative pressure chamber can be formed in the space below the piston plate 18. When the piston plate 18 is downward, the gas or liquid in the sealing tube 17 will be compressed.

[0030] The top of the slide bar 19 is fixedly connected with a trapezoidal plate 20 corresponding to the driving plate 7, and the slide bar 19 is slidably connected with the sealing cylinder 17. A spring 21 is sleeved on the slide bar 19, and the two ends of the spring 21 are fixedly connected with the trapezoidal plate 20 and the sealing cylinder 17 respectively.

[0031] In the present invention, the motor 8 drives the planetary gear reducer 10 to rotate, drives the connecting rod 11 to rotate, and drives the side scraper 5 to rotate, while driving the driving plate 7 to rotate. When the driving plate 7 rotates to the trapezoidal plate 20, it conflicts with the inclined surface of the trapezoidal plate 20. Under the guidance of the slide bar 19, the trapezoidal plate 20 drives the slide bar 19 to compress the spring 21 and slide downward, thereby pushing the piston plate 18 to move downward. When the driving plate 7 rotates to disengage from the trapezoidal plate 20, the spring 21 causes the trapezoidal plate 20 to reset upward, and the trapezoidal plate 20 drives the slide bar 19 and the piston plate 18 to automatically reset upward. The driving plate 7 thus reciprocates and conflicts with the trapezoidal plate 20, so that the piston plate 18 repeatedly performs piston motion in the sealing cylinder 17.

[0032] The transparent protective cover 4 has two outer walls on both sides fixedly connected with fixing rods 22 , and the outsides of the two fixing rods 22 are fixedly connected with circular rings 23 , and the circular rings 23 have cavities therein. A liquid inlet pipe 24 is fixedly connected between the cavity of the circular rings 23 and the sealing cylinder 17 .

[0033] A plurality of liquid spraying pipes 25 are fixedly connected to the top of the cavity of the circular ring 23 , and filter mesh holes 26 are fixedly connected to the tops of the plurality of liquid spraying pipes 25 . A liquid suction pipe 27 is fixedly connected to one side of the sealing cylinder 17 .

[0034] In the present invention, before drilling, the suction pipe 27 is connected to the water source. When the piston plate 18 repeatedly performs piston movement, the sealing cylinder 17 repeatedly sucks water through the suction pipe 27 and enters the ring 23 from the liquid inlet pipe 24. In this way, the water source in the ring 23 is sprayed out through multiple spray pipes 25. The water source passes through the filter mesh 26 to turn the water flow into mist water, which is sprayed out to reduce dust around the drilling hole, effectively reducing the dust generated during the drilling process. At the same time, the water mist can also reduce the temperature between the drill bit 9 and the coal mine, reduce the generation of sparks, and reduce the dust content in the air, which helps to protect the health of the workers. Then, the side scraper 5 and the lower scraper 6 are used to timely scrape the mixture of water and dust on the inner wall of the transparent protective cover 4, so that the operator can still observe the drilling situation in time.

[0035] Example 4: Reference Figure 4 , Figure 6 , Fig. 9 , which is basically the same as the first embodiment. Furthermore, a plurality of water outlet holes 28 are provided on the bottom wall of the transparent protective cover 4 , and the bottoms of the plurality of water outlet holes 28 are fixedly connected with a drain pipe 29 , and one end of the drain pipe 29 extends to the bottom of the mounting plate 3 .

[0036] In the present invention, when the anchor drill body 2 continues drilling, water flows into the transparent protective cover 4 and can be automatically discharged into the drain pipe 29 through the multiple water outlet holes 28 at the bottom of the transparent protective cover 4 without accumulating in the transparent protective cover 4. At the same time, the lower scraper 6 repeatedly scrapes the water outlet holes 28 of the transparent protective cover 4 to prevent the water outlet holes 28 from being blocked.

[0037] Embodiment 5: A method for using a directional hydraulic anchor drill for coal mining, which is operated by the following steps: S1. At the place where coal mining is required, adjust the position of the anchor drill body 2. By starting the hydraulic rod 1, the anchor drill body 2 can be pushed forward to drill holes in the coal mine. While the coal mine is being drilled, the coal mine splashed outward can be shielded by the transparent protective cover 4; S2. The drill bit 9 is driven to rotate by the motor 8 to drill holes in the coal mine. At the same time, the connecting rod 11 and the side scraper 5 can be driven to rotate by the planetary gear reducer 10. The side scraper 5 drives the lower scraper 6 to scrape off the coal mine particles and dust splashed on the side wall and bottom wall of the transparent protective cover 4, and observe the situation of the drill bit 9 and the progress of coal mining in time.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
