[0003] After searching, Chinese Patent CN208310839U discloses an unloading rack for a belt conveyor for linear lapping. By integrating the original two independent unloading racks and the tail frame, the unloading rack of the latter belt conveyor "rides" on the tail frame of the previous belt conveyor, leaving enough space for coal cleaning, replacing the tail roller and installing the head cleaner. Through integration, the situation of having to make two cement foundation platforms in the original technical means is reduced, directly reducing the manufacturing cost of the entire transfer point. The tail frame and the base are connected by bolts. When the tail roller needs to be replaced, only the bolts need to be removed and the tail frame can be replaced together. It can be seen that what this patent realizes is to leave space for cleaning and replacing the tail. When the belt conveyor performs oblique linear transportation, the rotation of the belt conveyor is adjusted, and the height of the belt conveyor close to the receiving structure does not change, which easily causes the materials on the belt conveyor to not be accurately sent into the receiving structure. This function is not realized by this patent. In order to perform oblique linear transportation according to the height of the receiving structure, an unloading rack for a belt conveyor is thus proposed. Content of the Utility Model
