[0032] Example

[0033] like Figure 1 and Figure 2 As shown, the present invention proposes an inclined ore body cutting well slotting device, including a rock drilling mechanism, a positioning and guiding mechanism, a propulsion mechanism and a slag discharge mechanism. The positioning and guiding mechanism includes a laser positioning transmitter 1 and a guide bracket. The laser positioning transmitter 1 is installed at the position of the rock drilling mechanism to provide directional guidance for drilling, and the guide bracket is fixed on the surface of the ore body to provide support and guidance for the drill rod.

[0034] like Figure 2 As shown, the laser positioning transmitter 1 includes a laser emitting module 11 installed inside it. The outer ring of the laser emitting module 11 has an annular groove 12, and a positioning groove 13 is provided on one side of the annular groove 12. A rotating protective cover 2 for dust protection is movably installed on the top of the laser emitting module 11. A locking protrusion 22 is fixedly connected to the bottom of the glass cover 21, and the locking protrusion 22 is engaged with the annular groove 12. The rotating protective cover 2 includes a glass cover 21 and an arc-shaped sliding groove 23 opened along its circumference. A positioning flange 24 is fixedly connected to the outer ring of the glass cover 21, and the positioning flange 24 is engaged with the positioning groove 13. Threaded mounting holes are provided on the positioning groove 13 and the positioning flange 24. Fastening bolts 25 are rotatably installed in the threaded mounting holes. The combination of the glass cover 21 and the laser emitting module 11 is shielded and protected to avoid damage to the equipment by gravel during construction and to extend the service life of the equipment.

[0035] like Figures 3-5As shown, a rotary cleaning assembly 3 is installed inside the arc-shaped sliding groove 23. The rotary cleaning assembly 3 includes a scraper 31 slidably installed inside the arc-shaped sliding groove 23. A guide limiting groove 26 located on the inner arc surface of the arc-shaped sliding groove 23 is also provided on the glass cover 21. Multiple rollers 32 are installed at one end of the scraper 31 located in the guide limiting groove 26. The rollers 32 can assist the scraper 31 in pushing and cleaning, thereby improving the smoothness of cleaning. The scraper 31 has an inverted "F" shaped structure. One protruding end of the scraper 31 is slidably installed in the guide limiting groove 26. A guide is provided on one side of the scraper 31 located above the glass cover 21. The guide seat 33 has a guide groove 331 inside. The positioning flange 24 is slidably disposed with the inner wall of the guide groove 331. The top of the guide groove 331 has a guide hole 332 that penetrates the top of the guide seat 33. A connecting plate 34 is slidably pulled out inside the guide seat 33. A connecting block 341 is fixedly connected to one end of the top of the connecting plate 34. A cylinder 35 connected to the upper surface of the guide seat 33 is connected to one side of the connecting block 341. The connecting block 341 penetrates the guide hole 332 and is slidably disposed with the inner wall of the guide hole 332. Multiple cleaning brushes 36 that contact the upper surface of the glass cover 21 are connected to the lower surface of the connecting plate 34 and the guide seat 33.

[0036] In the construction of cutting shaft slots in inclined ore bodies, the location and angle of the borehole are first determined using a laser positioning device, and the guide support is fixed in the corresponding position. Then, the hydraulic rock drill is started, and drilling operations are carried out using the drill rod. During the drilling process, the hydraulic cylinder of the propulsion mechanism pushes the rock drill slowly forward along the propulsion track, allowing the drill bit to continuously penetrate deeper into the ore body. At the same time, the laser positioning device continuously monitors the drilling direction, and if there is any deviation, the position of the rock drill can be adjusted in time.

[0037] As drilling progresses, the rock cuttings and dust generated by the drill bit are discharged from the borehole through the cuttings discharge pipe under the action of a negative pressure fan. The continuous operation of the cuttings discharge mechanism effectively maintains the cleanliness of the borehole, prevents rock cuttings from accumulating and affecting drilling efficiency and quality, and reduces dust pollution to the working environment.

[0038] According to the design requirements, multiple boreholes are drilled at different locations and angles in the cutting well. After drilling is completed, explosives are loaded into the holes for blasting. The energy generated by the blasting causes the ore body to break along the predetermined cutting line, forming a cutting groove. By rationally designing the arrangement of the boreholes, the amount of explosives used, and the detonation sequence, the blasting effect can be controlled, ensuring that the shape and size of the cutting groove meet the requirements of the mining process.

[0039] During the positioning and guidance process, the operator first aligns the engaging protrusion 22 of the rotating protective cover 2 with the annular groove 12 on the outer ring of the laser emitting module 11, presses down to engage the two, then inserts the positioning flange 24 into the positioning groove 13, and tightens it by rotating the threaded fastening bolt 25 to complete the rapid installation of the dustproof structure, forming a closed protective layer on the top of the laser emitting module 11 to prevent the intrusion of underground debris and dust.

[0040] During operation, the drilling mechanism performs drilling based on the guidance signal emitted by the laser emitting module 11. As construction continues, if dust or slag adheres to the surface of the laser emitting module 11 and affects the positioning accuracy, the operator uses the drive cylinder 35 to pull the connecting block 341, causing the connecting plate 34 to slide within the guide groove 331 of the guide seat 33. This extends the length of the guide seat 33 and the connecting plate 34, allowing the cleaning brushes 36 at their bottoms to contact the upper surface of the glass cover 21. Simultaneously, the scraper 31 is pushed, sliding within the track formed by the arc-shaped sliding groove 23 and the guide limiting groove 26. Multiple rollers 32 installed at the end of the scraper 31 roll in contact with the surface of the guide limiting groove 26, reducing frictional resistance and assisting the scraper 31 to move smoothly, thoroughly cleaning the surface of the laser emitting module 11. After cleaning, the cylinder 35 drives the connecting plate 34 to reset, ensuring that the laser emitting module 11 continuously and stably emits guidance signals, allowing the drill rod to complete the grooving operation in a precise direction under the support of the guide bracket.

[0041] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
