Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0028] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the utility model will be further described in detail below with reference to the drawings and specific embodiments.

[0029] Referring to Figures 1 to 7 The embodiment provides a kind of underground coal conveyor, comprising:

[0030] Several push blocks 3, several push blocks 3 are connected, and driving assembly is fixedly connected on push block 3;

[0031] The conveying belt is jointly driven to rotate by the driving assemblies, and is formed by a plurality of conveying plates 9 which are movably connected by the connecting shafts 8; the conveying plate 9 comprises a bottom plate 91, and side plates 92 are fixedly connected to the left and right sides of the bottom plate 91 in the conveying direction; and a back baffle 93 is fixedly connected to the top of the rear end of the bottom plate 91 in the conveying direction.

[0032] The plurality of push block baffles 3 are spliced with each other, the driving assemblies are fixedly connected to the push block baffles 3 and drive the conveying belt to rotate, the conveying belt is formed by a plurality of conveying plates 9 which are connected end to end, and the two side plates 92 and the back baffle 93 of the conveying plate 9 jointly form a concave space which can uniformly bear large, small and powdered coal and effectively avoid the blockage problem of the traditional scraper conveyor. The protruding back baffle 93 provides a horizontal power for the coal, which helps to adapt to the irregular or steep transportation route in the underground, thereby reducing the influence of the terrain on the transportation efficiency. The plurality of driving assemblies jointly drive the conveying belt, and the multi-point driving design ensures the transportation capacity in the long working face and reduces the risk of equipment failure.

[0033] The bottom plate 91 is provided with a front connecting pipe 94 fixedly connected to the bottom of the front side in the conveying direction and a rear connecting pipe 95 fixedly connected to the bottom of the rear side, and the connecting shaft 8 penetrates through the rear connecting pipe 95 of the front conveying plate 9 and the front connecting pipe 94 of the rear conveying plate 9 to movably connect the adjacent two conveying plates 9.

[0034] The front connecting pipe 94 and the rear connecting pipe 95 are connected by the connecting shaft 8, so that the conveying plates 9 and the conveying plates 9 connected with each other can also rotate by a certain angle, which is convenient for the bending of the conveying belt.

[0035] The bottom plate 91 is provided with a front connecting pipe 94 fixedly connected to the bottom of the front side in the conveying direction and a rear connecting pipe 95 fixedly connected to the bottom of the rear side, and the connecting shaft 8 penetrates through the rear connecting pipe 95 of the front conveying plate 9 and the front connecting pipe 94 of the rear conveying plate 9 to movably connect the adjacent two conveying plates 9.

[0036] The driving motor 1 is preferably a permanent magnet motor, which drives the conveying wheel 7 to rotate and in turn drives the conveying belt to rotate; the driving motor 1 and the conveying wheel 7 are connected by the shaft coupling 6, which can compensate for the relative displacement between the two shafts to a certain extent and has the functions of buffering, damping, safety protection and the like.

[0037] The bottom plate 91 is provided with a front connecting pipe 94 fixedly connected to the bottom of the front side in the conveying direction and a rear connecting pipe 95 fixedly connected to the bottom of the rear side, and the connecting shaft 8 penetrates through the rear connecting pipe 95 of the front conveying plate 9 and the front connecting pipe 94 of the rear conveying plate 9 to movably connect the adjacent two conveying plates 9.

[0038] The pushing baffle 3 is arranged on both sides and below the conveying belt, so that the pushing baffle 3 encloses the conveying belt and the conveying wheel 7, and when the conveying machine is pushed in the transverse direction, the pushing baffle 3 can be pushed to push multiple components at one time, and the central shaft of the conveying wheel 7 can also provide support force for the conveying belt and the conveying wheel 7.

[0039] The conveying wheel 7 is axially provided with a groove, and the front connecting pipe 94 and the rear connecting pipe 95 are embedded in the groove.

[0040] The groove on the conveying wheel 7 is embedded with the front connecting pipe 94 and the rear connecting pipe 95 on the conveying belt, thereby effectively driving the movement of the conveying belt. At the same time, the conveying wheel 7 provides necessary support for the conveying belt, ensuring that it can safely carry and transport coal.

[0041] The conveying wheel 7 is axially provided with a groove, and the front connecting pipe 94 and the rear connecting pipe 95 are embedded in the groove.

[0042] The dumbbell pin 4 allows a certain degree of flexibility, so that the two pushing baffles 3 can be moderately misaligned, which ensures that the new conveying machine can be pushed in the transverse direction and adapt to uneven working surfaces.

[0043] The conveying wheel 7 is axially provided with a groove, and the front connecting pipe 94 and the rear connecting pipe 95 are embedded in the groove.

[0044] The front connecting pipe 94 and the rear connecting pipe 95 have a gap between them, and when the conveying machine is pushed in the transverse direction, the front connecting pipe 94 and the rear connecting pipe 95 can be misaligned with each other, so that the conveying plate 9 being pushed moves in the transverse direction.

[0045] The conveying wheel 7 is axially provided with a groove, and the front connecting pipe 94 and the rear connecting pipe 95 are embedded in the groove.

[0046] The pushing ear 5 can be connected with the pushing mechanism of the hydraulic support used for transverse movement of the conveying machine, and the required transverse force can be transmitted.

[0047] Method for use

[0048] In the normal working state, the driving motor 1 installed on the motor support 2 drives the conveying wheel 7 in the conveying machine through the shaft coupling 6, so that it starts to rotate. The conveying wheel 7 is closely embedded with the front connecting pipe 94 and the rear connecting pipe 95 on the conveying belt, and the rotation of the conveying wheel 7 transmits power to the conveying belt composed of the conveying plate 9, thereby starting its transportation function.

[0049] When the conveyor needs to be pushed laterally, the hydraulic supports can apply a pushing force to the pushing ears 5 on the pushing baffle 3 through the pushing mechanism in sequence. Since the pushing baffle 3 is connected through the dumbbell pin 4 and has a certain flexibility, it can produce a moderate misalignment, causing the pushing baffle 3 to move laterally in the axial direction perpendicular to the conveying direction. Then, the pushing baffle 3 transmits this lateral movement force to the contacted conveying plate 9, causing a certain misalignment between the stressed conveying plate 9 and the unstressed conveying plate 9. This process causes the pushed part to be pushed a certain distance, after which the hydraulic supports will sequentially push all the pushing baffles 3, completing the overall lateral pushing of the conveyor.

[0050] During the pushing process, if the pushing distance exceeds the limit distance of a single pushing, the predetermined target can be achieved by repeating the pushing operation multiple times. This design enables the conveyor to flexibly cope with various complex working environments, ensuring its efficiency and adaptability in coal transportation. In addition, the efficiency of the overall pushing process also helps to improve the stability of the equipment operation and reduce the transportation risk caused by terrain changes.

[0051] As can be seen, the conveyor not only exhibits excellent performance in vertical transportation, but also through precise design and flexible structure, the lateral pushing function enables the equipment to maintain efficient transportation in various complex situations. All this ensures its wide application prospect and significant economic benefits in the coal industry.
