Description

Technical Field

[0001] This utility model relates to the technical field of drilling rig propulsion mechanisms, and in particular to a dustproof and sealed drilling rig propulsion mechanism. Background Technology

[0002] Drilling rigs are indispensable pieces of equipment in mining, geological exploration, and construction engineering. Their propulsion mechanisms are key components for feeding drill bits, adjusting drilling pressure, and ensuring drilling efficiency and stability. Currently, most drilling rig propulsion mechanisms on the market adopt guide rail sliding or screw drive structures. While these meet the basic requirements of drilling operations to a certain extent, under complex working conditions, especially in dusty, humid, high-temperature, or corrosive environments, the moving parts of traditional propulsion mechanisms, such as guide rails, sliders, or screws, are mostly open or semi-enclosed structures, lacking effective dustproof sealing measures. During drilling, a large amount of dust, rock cuttings, mud, and water generated can easily enter the moving gaps, causing component wear, jamming, or even failure, affecting the normal operation of the equipment.

[0003] Therefore, a dustproof and sealed drilling rig propulsion mechanism needs to be designed to solve the above problems. Utility Model Content

[0004] To overcome the shortcomings of poor dustproof sealing performance, this utility model provides a dustproof and sealed drilling rig propulsion mechanism.

[0005] The technical solution of this utility model is as follows: a dustproof and sealed drilling rig propulsion mechanism, including a support frame, a support rail, a mounting frame, a hydraulic cylinder, a pitching assembly, and a drilling rig. The support rail is fixedly connected to the rear inner side of the support frame, and the mounting frame is slidably connected to the support rail. The hydraulic cylinder is mounted on the mounting frame, and the pitching assembly is rotatably connected to the bottom output shaft of the hydraulic cylinder. The drilling rig is fixedly connected to the inner side of the pitching assembly.

[0006] Furthermore, it also includes a sealing shell, with the sealing shell fixedly connected to the upper inner side of the support frame, the hydraulic cylinder located inside the sealing shell, and two access pipes provided on the front side of the hydraulic cylinder, the two access pipes passing through the sealing shell and exposed on the surface.

[0007] Furthermore, it also includes a dust cover and a flap. The dust cover is fixedly connected to the lower inner side of the support frame. The pitching assembly and the drilling rig are located inside the dust cover. The flap is rotatably connected to the left side of the dust cover.

[0008] Furthermore, it also includes a liquid storage tank, a liquid pump, and a connecting pipe. The liquid storage tank is fixedly connected to the lower rear side of the support frame, the liquid pump is fixedly connected to the top of the liquid storage tank, the connecting pipe is fixedly connected to the top of the liquid pump, the connecting pipe is fixedly connected to the middle of the support frame, and the front side of the connecting pipe passes through the dustproof shell and is fixedly connected to the dustproof shell.

[0009] Furthermore, it also includes an atomizing nozzle, which is fixedly connected to the front side of the connecting pipe and is located on the top of the drilling rig.

[0010] Furthermore, a slot for fixing is provided on the front side of the bottom of the support frame, and an access pipe is provided on the rear side of the liquid storage tank.

[0011] Furthermore, the flap is designed as an arc-shaped flap, and a handle is provided on the flap.

[0012] Compared with existing technologies, the advantages of this technical solution are as follows:

[0013] This solution creates a dual-protection structure by enclosing the hydraulic cylinder with a sealed shell and protecting the pitching assembly and drilling rig with a dustproof shell. This effectively isolates dust from entering key moving parts and significantly improves the reliability and service life of the equipment in high-dust environments. Attached Figure Description

[0021] A dustproof and sealed drilling rig propulsion mechanism, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, it includes a support frame 1, a support rail 2, a mounting frame 3, a hydraulic cylinder 4, a pitching assembly 5, and a drilling rig 6;

[0022] The support frame 1 has a slot for fixing at the bottom front side. The support rail 2 is fixedly connected to the inner rear part of the support frame 1 by bolts. The mounting frame 3 is slidably connected to the support rail 2. The hydraulic cylinder 4 is installed on the mounting frame 3 by bolts. The bottom output shaft of the hydraulic cylinder 4 is rotatably connected to the pitch assembly 5. The drilling rig 6 is fixedly connected to the inner side of the pitch assembly 5 by bolts.

[0023] like Figure 1 As shown, it also includes a sealing shell 7. The upper inner side of the support frame 1 is fixedly connected to the sealing shell 7 by bolts. The hydraulic cylinder 4 is located inside the sealing shell 7. Two access pipes are provided on the front side of the hydraulic cylinder 4. The two access pipes pass through the sealing shell 7 and are exposed on the surface.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, it also includes a dust cover 8 and a flap 9. The dust cover 8 is fixedly connected to the lower inner side of the support frame 1 by bolts. The pitch assembly 5 and the drilling rig 6 are located inside the dust cover 8. The flap 9 is rotatably connected to the left side of the dust cover 8.

[0025] like Figure 2 , Figure 3 , Figure 4 and Figure 6 As shown, it also includes a liquid storage tank 10, a liquid pump 11, and a connecting pipe 12. The liquid storage tank 10 is fixedly connected to the lower rear side of the support frame 1 by bolts. An inlet pipe is provided on the rear side of the liquid storage tank 10. The liquid pump 11 is installed on the top of the liquid storage tank 10. The connecting pipe 12 is fixedly connected to the top of the liquid pump 11. The connecting pipe 12 is fixedly connected to the middle of the support frame 1, and the front side of the connecting pipe 12 passes through the dust cover 8 and is fixedly connected to the dust cover 8.

[0026] like Figure 4 and Figure 6 As shown, it also includes an atomizing nozzle 13, which is fixedly connected to the front side of the connecting pipe 12 and is located at the top of the drilling rig 6.

[0027] When this device is required for drilling operations:

[0028] The device is secured via the bottom slot, ensuring the support frame 1 is stable and the support rail 2 slides smoothly against the mounting frame 3. An appropriate amount of cleaning fluid is injected into the storage tank 10. The hydraulic cylinder 4 and drilling rig 6 are then activated. The mounting frame 3 slides along the support rail 2, achieving smooth pushing and moving the pitch assembly 5 and drilling rig 6 downwards, bringing the drilling rig 6 closer to the target rock layer. The drilling rig 6 and pitch assembly 5 are located inside the dustproof housing 8, preventing dust from directly contacting critical moving parts. The left-side flap 9 design facilitates regular cleaning and maintenance, improving equipment maintainability. The sealed housing 7 effectively prevents dust from entering the hydraulic cylinder 4. Internally, to ensure its long-term stable operation, the pitch component 5 can be adjusted according to the actual drilling angle, achieving flexible adaptation to drilling in inclined or vertical directions. The pump 11 is started, and the pump 11 delivers the liquid in the storage tank 10 to the connecting pipe 12, which is then sprayed out through the atomizing nozzle 13 to form a fine mist, covering the drilling rig 6 and the drilling area, effectively suppressing the dust generated during drilling, while cooling the drill bit and extending its service life. After drilling is completed, the hydraulic cylinder 4, the drilling rig 6 and the pump 11 are turned off, the flap 9 is opened to check the status of the drilling rig 6, and then the flap 9 is closed.

[0029] This solution utilizes a liquid spraying system comprised of a storage tank, a pump, and atomizing nozzles to continuously spray fine mist during drilling. This effectively suppresses dust dispersion, improves the working environment, cools the drill bit, reduces wear, and extends the lifespan of the drilling tools. The pitch assembly rotates around the output shaft, allowing for flexible adjustment of the drilling angle and supporting inclined or vertical drilling operations, enhancing the equipment's adaptability to different geological conditions and construction scenarios. The mounting frame and support rails, combined with hydraulic cylinder drive, ensure smooth and controllable drilling rig movements, improving positioning accuracy and operational efficiency during drilling, making it suitable for high-precision drilling tasks.
