[0002] With the continuous growth of global energy demand and the continuous advancement of science and technology, the coal mining industry, as an important pillar of energy supply, is undergoing unprecedented changes and development. From traditional manual mining to modern mechanized and automated production, the coal mining industry has made remarkable achievements in improving production efficiency, ensuring safe production, and reducing environmental pollution. However, in the face of increasingly severe resource constraints, environmental challenges and market competition, the coal mining industry still needs to continue to explore and innovate in order to seek a more efficient, environmentally friendly and sustainable development path.

[0003] In this context, the performance and efficiency of the scraper conveyor, as one of the main equipment for coal transportation in coal mines, is directly related to the overall benefits of coal mining operations.

The upper conveying mechanism 3 and the lower conveying mechanism 4 are both horizontally arranged between the two side plates 2 and staggered (i.e., the coal blocks dropped from the upper conveying mechanism 3 can just fall onto the lower conveying mechanism 4).

[0029] Preferably, an ultrasonic crushing device 5 and a plurality of spray heads 6 arranged at equal intervals along the upper edge of the front end of the side panels 2 are provided on the inner side walls of the two side panels 2 near the front end of the upper conveying mechanism 3 and the lower conveying mechanism 4; it is worth noting here that the installation positions of the plurality of spray heads 6 are all higher than the installation position of the ultrasonic crushing device 5.

[0030] In order to accurately detect the position and size of large volumes of coal, an ultrasonic level sensor is also provided on the side wall of the shell of the ultrasonic crushing device.

[0031] like Figure 2As shown, the upper transmission mechanism 3 includes a filter conveyor belt 301, a first driving wheel 303, a first driven wheel 304 and a plurality of first supporting wheels 305; wherein the filter conveyor belt 301 is tensioned by the first driving wheel 303, the first driven wheel 304 and a plurality of first supporting wheels 305 located between the first driving wheel 303 and the first driven wheel 304. The two ends of the first driving wheel 303, the first driven wheel 304 and the plurality of first supporting wheels 305 are rotatably connected to the mounting holes at the corresponding positions of the left and right side panels 2 through bearings respectively; the outer wall of the side panel 2 is provided with a first driving motor 10 at a position corresponding to the first driving wheel 303; the output shaft of the first driving motor 10 is connected to the wheel shaft of the first driving wheel 303 through a coupling, thereby realizing the transmission performance of the upper transmission mechanism 3.

[0033] It is worth explaining here that in order to avoid equipment wear or jamming of the transmission wheels due to coal blocks falling onto the transmission wheel bodies, a first guard wall 302 and a second guard wall 402 are arranged on the left and right sides of the filter conveyor belt 301 and the belt 401 along the length direction. The first guard wall 301 and the second guard wall 402 are fixed to the inner wall of the side plate 2 by a number of spaced connecting rods, and the spacing between the two first guard walls 302 is equal to the width of the filter conveyor belt 301; the spacing between the two second guard walls 402 is equal to the width of the belt 401.

[0034] like Figure 4As shown, the ultrasonic crushing device 5 includes a transducer 501 and an ultrasonic generator 502. The transducer 501 is arranged at the front end of the housing 503, and the ultrasonic generator 502 is arranged at the side of the front end of the transducer 501 away from the housing 503; it is worth noting that the outlet end of the ultrasonic generator 502 is directly opposite to the front end of the filter conveyor belt 301 of the upper transmission mechanism 3, so as to facilitate the crushing of large-sized coal blocks that are not filtered and diverted by the filter conveyor belt 301; the inner cavity of the housing 503 is provided with a controller and a cooling device; the transducer 501, the ultrasonic generator 502 and the cooling device are all controlled and adjusted by the controller. In order to ensure the effectiveness of the crushing, at least two groups of the ultrasonic crushing device 5 are provided.

[0035] Further preferably, a display 7 is also provided on one side of the top of the side panel 2 near the front end of the upper transmission mechanism 3, wherein the display 7 adopts a high-resolution touch screen design, which can display the working force of the ultrasonic crushing device 5, the water output of the sprinkler head 6 and other related parameters in real time, so as to facilitate the operator to monitor the operating status of the equipment in real time, record the operating data, and retain the historical data, thereby providing strong support for the maintenance and troubleshooting of the equipment; further, when an abnormality occurs during the operation of the conveyor, it can be discovered and handled in time.

[0036] Preferably, an electric control box 8 and an equipment box 9 are provided on the outer side wall of the side panel 2.

[0040] More preferably, in order to ensure the overall stability of the device, the base plate 1 and the side plate 2 are made of alloy steel material.

[0041] When in use, the coal is first placed on the filter conveyor belt 301 of the upper conveying mechanism 3 for preliminary diversion and screening, and small-volume coal blocks fall directly to the surface of the belt 401 of the lower conveying mechanism 4 through the mesh holes on the filter conveyor belt 301 and continue to be transported forward along the belt 401; while the large-volume coal blocks that have not been diverted and filtered continue to be transported forward along the filter conveyor belt 301, and the specific position of the coal to be crushed is accurately detected by the ultrasonic level sensor and crushed by the ultrasonic crushing device 5, and the crushed coal falls to the surface of the belt 401 of the lower conveying mechanism 4; at the same time, the sprinkler head 6 continues to work during the entire transmission process, on the one hand reducing the dust generated during the crushing, and on the other hand reducing the dust generated in the process of coal blocks falling from the upper conveying mechanism 3 to the lower conveying mechanism 4, thereby avoiding the impact of dust on the environment and the health of workers.

[0042] The present invention not only improves the efficiency of coal transportation and diversion and screening, thus achieving the purpose of energy conservation and environmental protection, but also avoids the waste caused by the falling of coal blocks by arranging protective walls on both sides of the conveyor belt, and even worse, avoids the wear of the equipment by falling into the equipment, thereby ensuring the service life of the equipment, reducing maintenance costs, and more effectively achieving the continuity and stability of transmission.
