Abstract
Description
Technical Field
[0001] This utility model relates to the field of coal mine transportation technology, specifically to a coal mine transportation and pushing device. Background Technology
[0002] Traditional coal mine transportation relies heavily on scraper conveyors or belt conveyors, but underground roadways are narrow and have varying slopes, resulting in poor equipment maneuverability and a tendency to jam. Existing pushing devices are mostly fixed or single-degree-of-freedom structures, making it difficult to adapt to the continuous directional adjustment requirements under complex working conditions. Especially in fully mechanized mining faces, the conveying direction needs frequent adjustments when hydraulic supports are moved. Traditional equipment requires manual positioning assistance, which is inefficient and poses safety hazards. In addition, large differences in coal block size and changes in humidity can easily cause the pushing mechanism to jam, leading to high maintenance costs. This patent addresses the above problems by proposing a modular adaptive coal mine transportation pushing device. Through a multi-directional articulated mechanism and an intelligent sensing linkage system, it achieves omnidirectional flexible transfer within the roadway, improving the continuity of coal transportation and the reliability of the equipment.
[0003] Chinese patent document CN210854479U discloses a coal mine transport and pushing device. It includes two positioning plates. Rotary shafts are movably installed on both sides of the front of the front positioning plate, extending through to the rear of the rear positioning plate. Rollers are fixedly installed on the outer side of the rotating shafts, located between the two positioning plates. The two rollers are movably connected by a conveyor belt. This coal mine transport device, by incorporating an exhaust fan, filter cartridge, and dust collection hood, draws air upwards through the exhaust fan, causing dust generated during coal transport by the conveyor belt to be drawn into the dust collection hood. The dust then reaches the filter cartridge and is filtered through a filter screen, corrugated mesh plate, and activated carbon plate before being discharged. This structure achieves good filtration, preventing smoke and dust from affecting nearby workers and residents, making it more user-friendly, and also avoiding environmental pollution.
[0004] Although the device described in the aforementioned literature can filter and reduce dust, its structure is relatively simple and the adjustment of the device's support frame is not flexible enough, making the device inconvenient to use. Furthermore, the suction nozzle of the dust collection component cannot be adjusted in angle, limiting the dust collection range. At the same time, the filter screen is prone to clogging, reducing the device's working efficiency. Utility Model Content

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] This utility model provides a coal mine transport and pushing device. The device is equipped with a support adjustment device, which allows for flexible adjustment of the tilt angle. This enables the coal mine transport equipment to achieve high efficiency, safety, and economy. Coal mine roadways have varying slopes, and the adjustable tilt angle allows the equipment to quickly adapt to the roadway undulations, avoiding material accumulation or slippage due to incompatible slopes. The same equipment can adapt to different transport needs through angle adjustment, reducing equipment model dependence. An appropriate tilt angle can accelerate the descent of materials by their own weight, reducing the drive power of the conveyor belt and saving energy consumption. The tilt design can prevent material stagnation, especially for wet or sticky coal. The tilt angle helps the material flow smoothly and improves transport continuity. The extension and retraction of the electric telescopic rod can move the sliding plate fixed by the connecting plate, causing the lower end of the hinge rod to slide and tilt at different angles along the sliding rod, thereby allowing the conveyor table to tilt at different angles to suit different heights of the discharge port.
[0019] This utility model provides a coal mine transportation and pushing device. This device is equipped with a dust collection and filtration system. Through innovative mechanical structure, it addresses the pain points of traditional dust collection equipment, such as rapid suction power decay and reliance on manual maintenance. It combines high efficiency, durability, and safety. The rotating suction nozzle can be flexibly adjusted to adapt to the dust removal needs of complex structures such as tunnel walls and equipment corners, reducing the blind spots of traditional fixed nozzles. Especially for irregular areas where coal is scattered or dust accumulates, the rotating suction nozzle can adjust its direction in real time during transportation, efficiently adhering to dust-generating points and preventing dust diffusion. The flexible angle adjustment of the rotating suction nozzle adapts to the dust removal needs of complex structures such as tunnel walls and equipment corners, reducing the blind spots of traditional fixed nozzles. Especially for irregular areas where coal is scattered or dust accumulates, the spring below the filter screen... The combination of the support and the rotating low rod forms a high-frequency micro-vibration mechanism. Through periodic tapping or rotational friction, it breaks down dust clumps clogging the filter holes, making it particularly suitable for humid or sticky coal dust environments. The vacuum cleaner drives the airflow to generate suction, drawing dust in from the nozzle and transporting it through the suction pipe to the filter box for filtration. Clean air is then discharged from the exhaust pipe, reducing pollution to the working environment. The second motor drives the tube frame to rotate, allowing adjustment of the nozzle angle and effectively increasing the equipment's suction range. In addition, spring supports are installed on both sides of the filter screen, allowing it to sway. The first motor drives the drive wheel to rotate, causing the driven wheel connected by the synchronous pulley to rotate as well. This causes the low rod at one end of the rotating rod to rotate, and its protruding end strikes the filter screen, causing it to vibrate and thus clearing the filter holes to prevent clogging and maintain filtration efficiency.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0027] like Figure 1 and Figure 5As shown, a coal mine transportation and pushing device includes a conveyor platform 1. A support adjustment device 2 is fixedly connected to the lower end of the conveyor platform 1. This device allows for flexible adjustment of the tilt angle, enabling the coal mine transportation equipment to achieve high efficiency, safety, and economy. Coal mine roadways have varying slopes; the adjustable tilt angle allows the equipment to quickly adapt to the roadway's undulations, preventing material accumulation or slippage due to inconsistencies in slope. The same equipment can adapt to different transportation needs through angle adjustment, reducing reliance on specific equipment models. An appropriate tilt angle allows the material's own weight to accelerate its descent, reducing the conveyor belt's drive power and saving energy. The tilt design prevents material stagnation, especially for wet or sticky coal; the tilt angle facilitates smooth material flow and improves transportation continuity. A base plate 3 is fixedly connected to the lower end of the support adjustment device 2, and a fixed frame 4 is fixedly connected to the upper right side of the conveyor platform 1. A dust collection and filtration device 5 is fixedly connected to the upper end of the fixed frame 4. This device addresses the pain points of traditional vacuum cleaners, such as rapid suction power decay and reliance on manual maintenance, through innovative mechanical structure. It combines high efficiency, durability, and safety. The rotating nozzle can be flexibly adjusted to adapt to the dust removal needs of complex structures such as tunnel walls and equipment corners, reducing the blind spots of traditional fixed nozzles. Especially for irregular areas where coal is scattered or dust accumulates, the rotating nozzle can adjust its direction in real time during transportation to efficiently adsorb dust from the dust-generating point, preventing dust diffusion. The spring support under the filter screen and the rotating rod combine to form a high-frequency micro-vibration mechanism, which breaks down dust clumps clogging the filter holes through periodic tapping or rotational friction. It is especially suitable for humid or sticky coal dust environments.
[0028] The support adjustment device 2 includes a first connecting frame 21, the upper end of which is fixedly connected to the lower end of the conveyor table 1.
[0029] The dust collection and filtration device 5 includes a filter box 51, the lower end of which is fixedly connected to the upper end of the fixing frame 4.
[0030] A base is fixedly connected to the lower end of the base plate 3, and a controller is fixedly connected to one side of the fixing frame 4.
[0031] like Figure 2As shown, the lower end of the first connecting frame 21 is movably connected to a hinge rod 22, the lower end of the hinge rod 22 is movably connected to a second connecting frame 23, the bottom of the second connecting frame 23 is slidably connected to a slide rod 24, a sliding plate 25 is fixedly connected to one side of the second connecting frame 23, a connecting plate 26 is fixedly connected to one side of the sliding plate 25, and an electric telescopic rod 27 is fixedly connected to one side of the connecting plate 26. The extension and retraction of the electric telescopic rod 27 can cause the sliding plate 25 fixed by the connecting plate 26 to move, causing the lower end of the hinge rod 22 to slide and tilt at different angles along the slide rod 24, thereby enabling the conveyor table 1 to tilt at different angles to accommodate different heights of the discharge port.
[0032] like Figure 3 As shown, a vacuum cleaner 52 is fixedly connected to the upper end of the filter box 51, and an exhaust pipe 53 is fixedly connected to the output end of the vacuum cleaner 52. A vibrating cleaning component 54 is fixedly connected inside the filter box 51. A protective box is fixedly connected to one side of the filter box 51. A suction pipe 55 is fixedly connected to the lower end of the filter box 51. A pipe frame 56 is fixedly connected to one end of the suction pipe 55. A nozzle 57 is fixedly connected to one side of the pipe frame 56. A connecting shaft 58 is movably connected to both ends of the pipe frame 56. A second motor 59 is fixedly connected to one end of the connecting shaft 58. The vacuum cleaner 52 drives the airflow to generate suction, which causes dust to be sucked in from the nozzle 57 and transported along the suction pipe 55 to the filter box 51 for filtration. After filtration, clean air is discharged from the exhaust pipe 53, reducing pollution to the working environment. The second motor 59 drives the pipe frame 56 to rotate, which can adjust the angle of the nozzle 57 and effectively improve the suction range of the equipment.
[0033] like Figure 4 As shown, the vibrating cleaning component 54 includes a first motor 541. The fixed end of the first motor 541 is fixedly connected to the left side of the filter box 51. The output end of the first motor 541 is fixedly connected to a drive wheel 542. Driven wheels 543 are drivenly connected to both sides of the drive wheel 542. A synchronous belt 544 is provided between the drive wheel 542 and the driven wheels 543. A rotating rod 545 is fixedly connected to one end of the driven wheel 543. A lower rod 546 is fixedly connected to one end of the rotating rod 545. The upper part of the lower rod 546 is fixedly connected to... A filter screen 547 is fixedly installed, and spring supports 548 are fixedly connected to both sides of the bottom of the filter screen 547. The spring supports 548 on both sides of the filter screen 547 allow the filter screen 547 to shake. The first motor 541 drives the drive wheel 542 to rotate, causing the driven wheel 543 connected by the synchronous pulley 544 to rotate as well. This causes the low rod 546 at one end of the rotating rod 545 to rotate, and the protrusion at one end strikes the filter screen 547, causing it to vibrate. This clears the filter holes and prevents blockage that could affect the filtration effect.
[0034] The working principle of this utility model is as follows: Through the support adjustment device 2, the extension and retraction of the electric telescopic rod 27 can move the sliding plate 25 fixed by the connecting plate 26, causing the lower end of the hinge rod 22 to slide and tilt at different angles along the sliding rod 24, thereby allowing the conveyor table 1 to tilt at different angles to accommodate material inlets of different heights. Using the dust collection and filtration device 5, the vacuum cleaner 52 drives the airflow to generate suction, causing dust to be sucked in from the suction nozzle 57 and transported along the suction pipe 55 to the filter box 51 for filtration. After filtration, clean air is discharged from the exhaust pipe 53. To reduce pollution to the working environment, the second motor 59 drives the tube frame 56 to rotate, which can adjust the angle of the suction nozzle 57 and effectively improve the dust collection range of the equipment. In addition, spring supports 548 are set on both sides of the filter screen 547 so that the filter screen 547 can shake. The first motor 541 drives the drive wheel 542 to rotate, causing the driven wheel 543 connected by the synchronous pulley belt 544 to rotate as well. This causes the low rod 546 at one end of the rotating rod 545 to rotate, and the protrusion at one end strikes the filter screen 547 to make it vibrate, thereby clearing the filter holes and preventing blockage that would affect the filtration effect.
