[0002] Long flame coal is a low-metamorphosis bituminous coal with the lowest degree of metamorphism. It is the youngest bituminous coal with a coalification degree only higher than that of lignite, ranging from non-adhesive to weakly adhesive. Long flame coal refers to high-volatile low-rank bituminous coal with a maximum reflectivity R of the vitrinite group between 0.50% and 0.65%.

[0003] After mining, coal needs to be crushed and screened into fine coal for use. Coal trucks transport low-metamorphic bituminous coal to processing plants. In many cases, it needs to be transported from a low place to a certain height, such as to a crushing device or drying equipment. They all need to be lifted to a certain height. At present, most workers push the transport cart after it is fully loaded. Workers need to continuously unload and load coal onto the cart using tools such as shovels, especially when transporting it to the vicinity of equipment. It is troublesome and laborious to shovel it into the equipment with a shovel. In this regard, we designed a loading device for low-metamorphic bituminous coal. Utility Model Content
