Moreover, the accumulated coal is located in the support on both sides of the belt conveyor head roller 3, and the staff needs to operate from the support gap when cleaning the accumulated coal, which is difficult to clean.

[0026] In the embodiment, the specification of outlet 14 is adapted to the specification of inlet 8, the size of inlet 8 is 600mm*600-1000mm, to ensure smooth coal falling, avoid blockage, improve coal conveying efficiency, and the longitudinal width of the upper port of coal falling hopper 6 is greater than the longitudinal width of conveying belt 2, which can more comprehensively receive the coal falling from conveying belt 2, and further reduce the coal accumulation.

[0027] In this embodiment, the grid buffer plate 10 is fixed on the right wall inside the capacity-increasing coal falling hopper 6, and the lower end of the grid buffer plate 10 is inclined to the left. When the coal falls from the conveying belt 2, the grid buffer plate 10 can slow down the falling speed of the coal, reduce the impact on the coal falling hopper and the coal falling pipe, and reduce the equipment wear; the inclined structure can also guide the coal to flow to the left side, so that the coal falls into the subsequent conveying link more uniformly.

[0028] In this embodiment, the flow baffle 9 is fixed on the upper end of the inlet 8 and inclined to the inside of the head coal falling pipe 5. The flow baffle 9 can shield and buffer the coal flow in the head coal falling pipe 5, ensure that the coal falls accurately into the head coal falling pipe 5, prevent the coal falling in the capacity-increasing coal falling pipe 7 from being hindered, affect the normal flow of the coal falling in the capacity-increasing coal falling pipe 7, and prevent the coal flow in the head coal falling pipe 5 from flowing backward into the capacity-increasing coal falling pipe 7.

[0031] The working principle of the capacity-increasing coal conveying belt machine head coal falling hopper is as follows:

[0032] In actual use, first, the inlet 8 is opened on the right side of the head coal falling pipe 5, and the flow baffle 9 is arranged inside the inlet 8. Then, the capacity-increasing coal falling hopper 6 is assembled and connected with the capacity-increasing coal falling pipe 7, the capacity-increasing coal falling hopper 6 is placed directly below the conveying belt 2 at the roller 3, the capacity-increasing coal falling hopper 6 is fixed and connected to the head coal falling hopper 4 through the connecting lug plate 11 and the bolts, so as to fix the head coal falling hopper 4. Then, the discharge port 14 at the lower end of the capacity-increasing coal falling pipe 7 is fixed and connected to the inlet 8, so as to realize the communication between the capacity-increasing coal falling pipe 7 and the head coal falling pipe 5. When the coal falls from the conveying belt 2, the longitudinal width of the upper end of the capacity-increasing coal falling hopper 6 is greater than that of the conveying belt 2, so as to ensure that the coal flow falls completely into the hopper. The coal falls into the capacity-increasing coal falling hopper 6, the coal flow is divided into multiple small flows by the grid buffer plate 10, the impact force is dispersed, the impact of the coal flow on the capacity-increasing coal falling hopper 6 is reduced, and the buffer plate is inclined to the left at the lower end, so as to make the coal flow spread horizontally and avoid local accumulation. The coal flow flows into the capacity-increasing coal falling pipe 7 through the capacity-increasing coal falling hopper 6, and finally flows into the head coal falling pipe 5 through the capacity-increasing coal falling pipe 7, so as to realize the collection and conveying of the accumulated coal.
