Description

Rear breast board mechanism of container of dump truck

Technical Field

The utility model relates to a tipper packing box technical field, concretely relates to tipper packing box back breast board mechanism.

Background

The conventional dumper rear breast board device mainly comprises a rear breast board hinge seat assembly and a locking mechanism assembly. The functions are mainly as follows: in the lifting process of the dump truck, the locking mechanism releases the locking effect on the rear breast board due to the effect of various rod mechanisms, so that the rear breast board rotates around the hinge seat assembly due to the self gravity effect and is automatically opened so as to complete the unloading process of the dump truck. These conventional tailgate devices all have to rely on the lifting process to open the tailgate, and are clumsy and insensitive, and the opening angle of the tailgate is also affected by the lifting angle of the car, which all make the dump truck have many disadvantages in use, such as: when materials with small volume are transported, the goods are dumped without opening the rear door, and the rear door device are easily damaged by the generated impact force; in addition, after the cargoes are unloaded, the rear breast board is arranged above the cargoes due to cargo accumulation, and the dump truck travels forwards, so that the rear breast board is suddenly supported by no object, and the rear breast board rapidly falls to smash the truck body to cause abrasion.
