[0031] The output roller 103 can be driven to rotate by driving motor 104, so that the conveyor belt 107 outside the output roller 103 and the driven roller 105 can rotate. When the coal excavated by the coal mine heading machine falls on the conveyor belt 107, the coal can be transported backwards by the rotation of the conveyor belt 107.

The inclined surface at the end of the push plate 609 can push the connecting rod 605 to move downward, so that the card member 603 is moved out of the card slot 601, and the lock of the winding roller 402 can be released, which is very convenient to use.

[0037] As an embodiment of the present invention, please refer to Figure 7 , Figure 8 , Fig. 9 and Fig.10 The trigger assembly includes a trigger plate 701, a groove is formed at the end of the head plate 112, and the trigger plate 701 is movably arranged in the groove, a pressure sensor 2 702 is fixedly arranged on the inner wall of the groove, and a pressure sensor 3 703 is fixedly arranged on the inner wall of one side of the embedded groove 114. When the head plate 112 is embedded in the groove 114 of the tail plate 110, the trigger plate 701 at the end of the head plate 112 will hit the pressure sensor 3 703 in the embedded groove 114, and the pressure sensor 2 702 in the groove of the head plate 112 will also detect a pressure signal, prompting the winding roller 402 in the transportation device corresponding to the pressure sensor 3 703 in the tail plate 110 to stop winding and causing the locking assembly to lock the winding roller 402, and prompting the winding roller 402 in the transportation device corresponding to the pressure sensor 2 702 in the head plate 112 to start winding and perform a traction operation on the subsequent transportation device, so that the use effect is better.

[0038] When in use, the output roller 103 can be driven to rotate by driving the motor 104, so that the conveyor belt 107 outside the output roller 103 and the driven roller 105 can rotate. When the coal excavated by the coal mine boring machine falls on the conveyor belt 107, the coal can be transported backwards by the rotation of the conveyor belt 107. During the transportation process, the coal will exert downward pressure on the conveyor belt 107, causing the conveyor belt 107 to sink toward the middle. At this time, the conveyor belt 107 can be lifted by the supporting mechanism to avoid damage to the conveyor belt 107 caused by the excessive weight of the transported coal, and to reduce the load on the output roller 103 and the driven roller 105. At the same time, the supporting mechanism can also adjust the supporting depth according to the conveying amount of the coal, so that it is more flexible to use. Furthermore, the position of the driven roller 105 can be adaptively controlled by the tensioning self-adjusting mechanism to achieve the purpose of adjusting the tension of the conveyor belt 107, so that the conveyor belt 107 is maintained at an appropriate tension. The coal mine transportation process is more stable, and multiple transportation devices for transporting coal mines can be docked end to end, so that the head plate 112 of the transportation device is located in the tail plate 110 of the adjacent transportation device, so that the coal mine can be relayed through multiple transportation devices, and the transportation device close to the coal mine boring machine can be equipped with a walking drive unit. When the coal mine boring machine excavates forward for a distance, in order to ensure that the coal discharged by the coal mine boring machine can fall on the conveyor belt 107, the transportation device can be driven by the walking drive unit to move toward the coal mine boring machine. After the transportation device close to the coal mine boring machine moves, it can automatically pull the transportation device at its tail end under the traction of the self-traction mechanism, so that the adjacent transportation devices continue to maintain a head-to-tail docking state, and there is no need to stop excavation and have staff enter the mine to adjust the position of the transportation device. While improving work efficiency, it also greatly improves the safety of the coal mine excavation process, and the use effect is better.

[0039] It should be particularly noted that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
