[0031] The support block 4 forms a sliding structure with the transport device housing 1 through the automatic telescopic rod 3, and the automatic telescopic rod 3 is symmetrically distributed about the longitudinal center line of the transport device housing 1, which is conducive to improving the stability of the support block 4 when sliding and avoiding the tilting of the support block 4 when sliding;

[0032] The gear 7 forms a linkage structure with the support block 4 through the first connecting shaft 8, and the connection mode between the gear 7 and the protrusion 6 is a meshing connection, and the protrusions 6 are evenly spaced in the first receiving groove 5, which facilitates the support block 4 to drive the gear 7 to slide through the first connecting shaft 8 when sliding, so that the gear 7 rotates under the limiting effect of the protrusion 6 when sliding, thereby facilitating the subsequent flipping and unloading, and improving the convenience of unloading operation;

[0033] The adjusting block 10 and the protective shell 9 form a rotating structure, and the pull rope 11 forms a sliding structure through the adjusting block 10 and the protective shell 9, so that the adjusting block 10 drives the pull rope 11 to slide when rotating, which facilitates the subsequent adjustment operation;

[0037] The connection between the first protective cover 19 and the second protective cover 20 is a snap-fit ​​connection, and the connection between the first protective cover 19 and the second protective cover 20 is an "L"-shaped structure when viewed from the side, which is beneficial for protecting dust in the coal mine, avoiding pollution to the surrounding environment during transportation, and improving safety and environmental protection.

[0038] The working principle of this embodiment: Figure 1-4 and Figure 8As shown, first, the staff puts the transport device shell 1 and the transport wheels 2 to the appropriate position, and then puts the coal mine into the inside of the supporting bottom plate 13. When the loading is completed, the transport device shell 1 is pushed for transportation. At this time, the first protective cover 19 and the second protective cover 20 can effectively protect the dust in the coal mine, avoid dust pollution to the surrounding environment during transportation, and improve the environmental protection and safety of the overall device. After transporting to the appropriate position, the staff starts the automatic telescopic rod 3, so that the automatic telescopic rod 3 pushes the support block 4. At this time, the support block 4 drives the gear 7 through the first connecting shaft 8. The gear 7 slides in the first receiving groove 5, and the gear 7 rotates under the limiting effect of the protrusion 6 during sliding, so that the gear 7 drives the protective shell 9 to rotate through the first connecting shaft 8, so that the protective shell 9 drives the supporting bottom plate 13 to rotate, and the supporting bottom plate 13 drives the supporting side plate 17, the first protective cover 19 and the second protective cover 20 to rotate during rotation. After rotating 180°, under the influence of the pushing of the coal mine, the first protective cover 19 and the second protective cover 20 rotate on the third connecting shaft 18, thereby completing the opening operation of the unloading port of the supporting bottom plate 13, thereby improving the convenience of overall unloading;

[0039] according to Figure 1 and Figure 5-8 As shown, during the unloading process, the material is often not completely unloaded, which reduces the efficiency of subsequent transportation. At this time, the staff can rotate the adjusting block 10 to make the adjusting block 10 drive the pull rope 11 to slide, and the pull rope 11 drives the connecting rod 12 to rotate when sliding, and the connecting rod 12 drives the supporting bottom plate 13 to slide when rotating, so that the coal mine can be effectively pushed during the unloading process, thereby improving the efficiency of unloading. At the same time, the supporting bottom plate 13 drives the supporting side plate 17 to slide when sliding. When the supporting side plate 17 slides and connects to the ground, the adjusting block 10 is continued to be rotated so that the supporting side plate 17 is connected to the ground through the connecting rod 12. It is impossible to slide under the action of the ground limit, so that the support side plate 17 rotates on the second connecting shaft 16 in the second storage groove 15, thereby completing the deployment of the support side plate 17, which is conducive to complete unloading, thereby improving the overall transportation work efficiency. When the unloading is completed, the staff rotates the adjustment block 10 in the reverse direction to loosen the pull rope 11. At this time, the connecting rod 12 is reset by the volute spring 14, so that the support bottom plate 13 slides in the opposite direction and drives the support side plate 17 to slide synchronously, so that the support bottom plate 13 and the support side plate 17 are re-stored into the protective shell 9, which is convenient for subsequent transportation work.
