Except for self-unloading trucks, the materials on other trucks are unloaded manually. Self-unloading trucks have a heavy body, high transportation costs, and a small amount of loaded materials, which are often unacceptable to users. Therefore, non-self-unloading trucks account for the absolute majority in the transportation field. Manual unloading has a large labor intensity and low work efficiency. Therefore, it is particularly urgent to solve the problem of quick unloading of bulk materials transported by non-self-unloading trucks or containers in different sites, especially for enterprises, ports, and yards with large demand. At present, the existing automotive hydraulic tipping unloading machines use a blocking plate to block the wheels of trucks, and the blocking plate of the existing unloading machine is fixed, and the blocking height of the blocking plate cannot be adjusted. As a result, when the blocking plate is too high, it is easy to scratch the rear bumper and chassis of the car, and when the blocking plate is too low, it cannot effectively block the wheels, causing the car to slide, thereby reducing the safety of the unloading machine.
