[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a dump truck body.
[0004] The technical solution provided by this utility model is: a dump truck body, characterized in that it includes a truck body underframe assembly, a truck body side panel assembly, a truck body front panel assembly, a truck body swing arm assembly, and a truck body rear panel assembly; the truck body underframe assembly has symmetrically arranged outwardly bent edges on both sides, and the bent edges have mounting holes in the longitudinal direction; the front end of the truck body underframe has a perforated mounting plate; the truck body side panel assemblies are symmetrically arranged on both sides of the truck body underframe assembly, the lower part of the truck body side panel assembly has outwardly bent edges, and the bent edges have mounting holes in the longitudinal direction; the front end of the truck body side panel has a perforated mounting plate; the truck body front panel assembly has mounting holes; the upper side of the truck body rear panel assembly has symmetrically arranged mounting holes; the truck body swing arm assembly has holes, and the truck body swing arm assemblies are symmetrically arranged on both sides of the truck body side panels;
[0005] The outward bending edges on both sides of the carriage underframe assembly match the outward bending edges at the bottom of the carriage side panel, with a total bending angle of 180°. The longitudinal distribution of the holes on the carriage underframe assembly and the carriage side panel is consistent, meaning the hole positions coincide. The two are connected by bolts and nuts.
[0006] The mounting plates with holes at the front of the underframe assembly and the side panel assembly correspond one-to-one with the mounting holes on the front panel assembly, and the two are connected by bolts and nuts.
[0007] The side of the carriage side panel assembly has mounting holes, and carriage swing arm assemblies are symmetrically arranged on it. The carriage swing arm assemblies rotate around the arrangement point.
[0008] The mounting holes symmetrically arranged on the upper side of the rear panel assembly of the carriage correspond one-to-one with the mounting holes at the rear end of the carriage swing arm assembly, and the two are connected by bolts and nuts.
[0009] Furthermore, the various components of the carriage are connected and fixed by bolts and nuts, and the carriage can be disassembled.
[0010] The beneficial effects of this utility model are as follows: In the dump truck body assembly, each assembly of the truck body is connected and fixed by bolts, and is detachable; the dump truck body is easy to transport in separate assemblies, and the installation is not limited by the working environment such as welding, and the assembly is convenient.

[0015] To better understand and implement this invention, the following detailed description is provided in conjunction with the accompanying drawings.
[0016] like Figure 2 , 3 As shown, a dump truck body has symmetrically arranged outwardly bent edges on both sides of the truck body underframe assembly 1, with mounting holes along the longitudinal direction of the bent edges. Side panels are symmetrically arranged on both sides of the truck body underframe assembly 1. The lower part of the side panel assembly 2 also has bent edges and mounting holes along the longitudinal direction of the truck body. The bent edges of the truck body underframe assembly 1 and the side panel assembly 2 mate with each other, and the holes correspond one-to-one. They are connected by bolts 6 and nuts 7. The mounting holes on the front panel assembly 3 are the same as the holes on the perforated mounting plates at the front of the truck body underframe assembly 1 and the side panel assembly 2. The components are connected in a one-to-one correspondence using bolts 6 and nuts 7. The side of the side panel assembly 2 has mounting holes on its side, on which the side panel arm assembly 4 is symmetrically mounted. The side panel arm assembly 4 can rotate around the mounting point. The mounting holes symmetrically arranged on the upper side of the side panel assembly 5 correspond one-to-one with the mounting holes at the rear end of the side panel arm assembly 4, and are connected using bolts 6 and nuts 7. The bolts 6 and nuts 7 are used to connect and fix the various assemblies together to form a dump truck body. Similarly, the bolts 6 and nuts 7 can be removed from this dump truck body to disassemble it into individual assemblies.
[0017] The present application discloses a dump truck body in which the various assemblies of the truck body are connected and fixed by bolts, and are detachable. The dump truck body is easy to transport in separate assemblies, and its installation is not limited by the working environment such as welding, and it is easy to assemble.
[0018] The above-described embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and improvements made by those skilled in the art to the technical solution of the present utility model without departing from its design spirit should fall within the protection scope defined by the claims of the present utility model.
