[0050] The working principle of the above embodiment is:

[0051] The conveyor belt docking mounting seats 3 connected to the material holes 2 installed on both sides of the diverter seat 1 make it convenient to install the conveyor belts on the conveyor belt docking mounting seats 3 on both sides by fastening screws, so as to ensure that a passage is formed between the two conveyor belts, the two conveyor belt docking mounting seats 3, the two material holes 2 and the diverter seat 1, so that when the coal mine is input to the material hole 2 connected to the input conveyor belt through the conveyor belt on one side, the conveyed coal blocks enter the crushing cylinder 5 connected to the drop barrel 4 through the side material hole 2, and at the same time, the crushing roller 7 is driven by the driving motor 6 to rotate to realize the crushing of the entered coal blocks, and the screening net 8 is cooperated to isolate the uncrushed coal blocks, so that the crushed coal blocks fall under the screening net 8, and the cylindrical seat 9 and the partition 10 are cooperated to divide the crushing cylinder 5 into multiple spaces, and the crushed coal blocks are stored in separated sections;

[0052] In coordination, a plurality of conveying pipes 11 are provided to be connected to each compartment space, and the motor 12 is provided to drive the spiral conveying roller 13 to rotate, and at the same time, the coal blocks in each compartment space are spirally conveyed to the discharge pipe 15 connected to the conveying pipe 11 for discharge to avoid discharge blockage, and it is convenient for a plurality of trucks to drive under each discharge pipe 15 to receive materials, and it is avoided to use a plurality of excavators to load materials. At the same time, when it is not necessary to use trucks to transport the coal mine, by starting the servo motor 16 on each discharge pipe 15 to drive the switch plate 17 to rotate to block the discharge port of the discharge pipe 15, at this time, the motor 12 and the drive motor 6 stop working synchronously, so that the coal blocks cannot be discharged from the discharge The coal is discharged from the pipe 15, and at the same time, the electric push rod 20 set in the start-up setting is used to push the loading seat 19 to be inserted into the diverter seat 1 to seal the bottom opening of the diverter seat 1 to prevent the coal blocks from falling into the blanking barrel 4, so that the coal transported on the conveyor belt installed on one side of the conveyor belt docking mounting seat 3 is transported to the diverter seat 1 and then falls on the roller 22 on the loading seat 19. In conjunction with the continuous transportation of the conveyor belt and the rolling guidance of the roller 22 on the coal, the coal is further pushed to the conveyor belt on the other side of the diverter seat 1 to continue to transport the coal to other destinations for storage, which effectively combines the conveyor belt transportation and the truck transportation, facilitates multi-channel and multi-point transportation, and greatly saves the cost of coal transportation.
