Description

Technical Field

[0001] This utility model relates to the field of coal mining technology, and in particular to a mining tool for coal mining. Background Technology

[0002] Coal drill rods are used in conjunction with various drilling rigs and employ spiral drilling technology, featuring fast drilling speed, good borehole formation, and high drilling efficiency. They offer significantly faster drilling speeds than traditional methods and are widely used in drilling and mining operations in coal mines, gypsum mines, and other similar locations.

[0003] Patent CN223282059U discloses a drilling device for coal mining. In use, a support ring is moved to the area to be drilled, and a pusher seat slides down along a limiting rod. The drilling cylinder on the pusher seat is then pushed into the borehole. During drilling, a spiral pusher lifts the mud blocks in the borehole upwards, ensuring unobstructed drilling. The pushed mud blocks enter a sampling cylinder, which is then fed out by a spiral feeder for easy collection by workers. However, this device has the following drawback: because it lacks a depth detection function, workers cannot directly determine the drilling and mining depth. This deficiency leads to other problems: workers can only estimate the mining depth based on experience or use external auxiliary equipment to measure it. Estimated depths may be inaccurate, and using external auxiliary equipment requires workers to remember and carry the equipment, further increasing their workload.

[0004] Therefore, how to design a coal mining tool with depth detection function so that it can directly display the mining depth during the mining operation has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The present invention aims to provide a mining tool for coal mining to overcome the shortcomings mentioned above.

[0018] Furthermore, an observation needle is provided at the upper end of the observation plate, with the tip of the observation needle facing the scale line.

[0019] Compared with existing technologies, this invention has at least the following advantages: In use, the device is first secured to the ground using the fixing components on the base plate. The lifting component on the upright plate is then activated, causing its lifting end to move the mining component downwards, passing through the through-holes in the base and upright plates for mining operations. Simultaneously, the observation plate connected to the lifting end of the lifting component moves synchronously with the mining component, with one end sliding along the limiting groove and the other end always corresponding to the scale line. Workers can directly read the mining depth by observing the position of the observation plate on the scale line, eliminating the need for estimation or additional equipment, thus achieving real-time display of depth during the mining process and improving operational efficiency.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Reference Figure 1-2 This utility model provides a mining tool for coal mining, including four fixed components for connecting to the ground arranged on a base plate 1, with the four fixed components set at the four corners; a vertical plate 2 with a longitudinal cross-section of "U" shaped is fixedly connected to the upper end of the base plate 1, and the side wall of the vertical plate 2 is provided with scale lines 3 and limiting grooves 4 along the vertical direction, with the scale lines 3 and limiting grooves 4 arranged opposite to each other; a lifting component is arranged on the vertical plate 2, with a mining component at its lifting end, and both the base plate 1 and the vertical plate 2 are provided with through holes 5, with the through holes 5 and the mining component arranged opposite to each other; an observation plate 6 is fixedly connected to the side wall of the lifting end of the lifting component, and the transverse cross-section of the observation plate 6 is also "U". One end of the observation plate 6 slides through the limiting groove 4, and the other end faces the scale line 3. The observation plate 6, in conjunction with the scale line 3, determines the mining depth, and the limiting groove 4 provides guidance for the sliding of the observation plate 6.

[0031] Reference Figure 1 and Figure 4 The base plate 1 has vertically arranged fixing holes corresponding to four fixing components. The fixing components include fixing rods 7 and cones 8. Fixing rods 7 and cones 8 are fixedly connected, and fixing rods 7 and fixing holes are slidably connected.

[0032] Reference Figure 4-6The fixed rod 7 has a vertically arranged movable groove 9 inside, and a vertical rod 10 is rotatably connected inside the movable groove 9. The side wall of the vertical rod 10 is provided with two first fixing rings 11, and the first fixing rings 11 are provided with four arc-shaped grooves 12. The arc-shaped grooves 12 are slidably connected to the limiting rod 13. The lower end of the limiting rod 13 is fixedly connected to the fixing nail 14. The fixed rod 7 is provided with sliding grooves 15 corresponding to the fixing nails 14. The fixing nails 14 are slidably connected to the sliding grooves 15. The end of the fixing nail 14 facing the sliding groove 15 is conical. The upper end of the vertical rod 10 is provided with two rotating rods 16. By rotating the vertical rod 10 through the rotating rods 16, the limiting rod 13 is driven to slide along the arc-shaped groove 12, thereby driving the fixing nail 14 to extend and retract into the sliding groove 15. The fixing nail 14 extending out of the sliding groove 15 is connected to the soil layer to enhance the fixing effect.

[0033] To prevent the rotating rod 16 from rotating due to accidental contact, a second fixing ring 17 is provided at the upper end of the fixing rod 7. The second fixing ring 17 is provided with two connecting holes 18. The rotating rod 16 is provided with a limit pin 19, which slides through the rotating rod 16 and connects to the connecting holes 18.

[0034] The lifting assembly includes a first motor 20, a screw 21, and a support plate 22. The first motor 20 is installed on the top of the upright plate 2. The screw 21 is vertically rotatably connected inside the upright plate 2. The output shaft of the first motor 20 is connected to the screw 21. The screw 21 is threadedly connected to the support plate 22. The side wall of the support plate 22 is fixedly connected to the observation plate 6.

[0035] Reference Figure 1 and Figure 3 The mining assembly includes a second motor 23, an auger rod 24, a drill bit 25, and a cylinder 31. The second motor 23 is located on the upper end of the support plate 22. The output shaft of the second motor 23 passes vertically through the support plate 22 and the auger rod 24 for transmission. The lower end of the support plate 22 is fixedly connected to the cylinder 31, which is sleeved around the auger rod 24. The lower end of the auger rod 24 is provided with the drill bit 25, which is located below the cylinder 31. The side wall of the cylinder 31 near the upper end is provided with a discharge port 26. When the support plate 22 drives the mining assembly to rise and fall, the auger rod 24, the drill bit 25, and the cylinder 31 pass through the through hole 5 of the vertical plate 2 and the through hole 5 of the bottom plate 1 in sequence.

[0036] Reference Figure 1 A conveyor plate 27 is inclinedly arranged on the side wall of the cylinder 31. The conveyor plate 27 is located at the discharge port 26, and the edge of the conveyor plate 27 is inclined outward.

[0037] Reference Figure 2The side wall of the upright plate 2 is provided with a hand-held push rod 28. The hand-held push rod 28 is movably mounted with a wheel 29 via a pivot. The lower end of the wheel 29 is flush with the lower end of the base plate 1. When moving the device, the operator first steps on the lower end of the hand-held push rod 28, then grasps the upper end of the hand-held push rod 28 and presses it down to separate the base plate 1 from the ground and move it upward. Then, the operator can push the hand-held push rod 28 to move the device.

[0038] An observation needle 30 is provided at the upper end of the observation plate 6. The tip of the observation needle 30 faces the scale line 3. The distance from the tip of the observation needle 30 to the scale line 3 is less than the distance from the concave surface of the observation plate 6 to the scale line 3, so that the staff can read the scale more accurately.

[0039] The working principle of this utility model is as follows: In use, the operator moves the device to the designated location for coal mining by using the push rod 28 and wheels 29. After the device is in place, the fixing rod 7 is inserted downward into the ground through the fixing hole on the base plate 1. Then, the limiting pin 19 on the rotating rod 16 is pulled out from one of the connecting holes 18, and the rotating rod 16 is rotated. The rotating rod 16 drives the vertical rod 10 to rotate in the movable groove 9. When the vertical rod 10 rotates, the arc groove 12 of the first fixing ring 11 on its side wall will drive the limiting rod 13 to slide outward along the sliding groove 15, thereby driving the fixing nail 14 to extend out of the sliding groove 15 and insert into the soil layer. When the rotating rod 16 rotates to the other connecting hole 18, the limiting pin 19 is slid through the rotating rod 16 and inserted into the other connecting hole 18. At this time, the fixing nail 14 is connected to the soil layer.

[0040] Then, the first motor 20 and the second motor 23 are started. The first motor 20 drives the screw 21 to rotate, and the rotation of the screw 21 drives the bearing plate 22 to move vertically. The bearing plate 22 then drives the mining component and the observation plate 6 to rise and fall synchronously. During the rising and falling process, one end of the observation plate 6 slides along the limiting groove 4. The operator determines the rising and falling height of the mining component by the value of the scale line 3 on the side wall of the vertical plate 2 aligned with the tip of the observation needle 30 at the upper end of the observation plate 6. The second motor 23 drives the auger rod 24 to rotate, and the drill bit 25 at the lower end of the auger rod 24 rotates together with the auger rod 24 to crush and mine the coal seam. The crushed coal seam is conveyed upward along the auger rod 24 under the action of the rotation of the auger rod 24 and discharged from the discharge port 26. Then it slides down along the conveyor plate 27 into the external collection structure.
