[0002] A coal mine refers to a place where coal resources are mined underground or in the open air. As a fossil fuel, coal mines are an important part of the global energy structure and are mainly used in power generation, heating, industrial production and other fields. The mining and operation of coal mines involve multiple links, mainly including exploration, mining, transportation, washing and sales. Among them, the coal mine conveyor belt is one of the indispensable important equipment in the process of coal mining and transportation. It is mainly used for the continuous transportation of coal and other bulk materials in underground coal mines or open-pit coal mines.

[0003] At present, due to the large amount of coal conveyed by the coal conveyor belt, the conveyor belt will break after long-term use, causing coal to spill. In the process of transportation, some coal will spill from both ends of the conveyor belt, and the spilled coal will fall onto the conveyor belt mounting frame and the ground, which is not convenient for the staff to quickly clean up later and is rather troublesome.

[0030] Among them, see Figure 6 As shown, the fixed supporting plate 9 is fixed to the inner wall of the discharge port, and the upper end surface of the fixed supporting plate 9 is provided with a guiding slope 11 inclined toward the movable supporting plate 10. The guiding slope 11 arranged on the fixed supporting plate 9 facilitates guiding the coal spilled into the aggregate frame 3 to the area where the movable supporting plate 10 is located at one end by relying on the action of gravity.

[0031] In the specific implementation of the present utility model, refer to Figure 4 and Figure 5 As shown, the flip assembly 4 includes:

[0032] A servo motor 41, the servo motor 41 is mounted on the outer wall of the aggregate frame 3;

[0033] A first gear 42, which is mounted on an output end of the servo motor 41 via a connecting shaft;

[0034] A second gear 43, the second gear 43 is meshed and connected to the first gear 42;

[0036] Through the above technical solution:

[0037] During specific use, the rotation of the driving roller 5 drives the conveyor belt 2 to rotate, so as to transport the coal added to the conveyor belt 2.

[0038] When the conveyor belt 2 breaks or the transported coal falls from both ends of the conveyor belt 2, the fallen coal can enter the concave frame 1, and then the guide plate 8 guides the scattered coal to automatically enter the nearest collection frame 3 for collection;

[0039] When it is necessary to collect coal from the aggregate frame 3, a collection box (box) can be placed at the bottom of the discharge port of the aggregate frame 3, and then the servo motor 41 is started, and the output end of the servo motor 41 is used to drive the first gear 42 to rotate, and the second gear 43 in meshing connection is used to drive the connecting rod 44 to rotate, so that the hinged movable supporting plate 10 is flipped downward to open one end of the discharge port.
