Packing box of dump truck

Abstract

The invention discloses a packing box of a dump truck. The packing box comprises a packing box body, a tail beam, a hinge seat, a front plate assembly, a rear dropside assembly and a clapboard, wherein the upper edges of side plates are outwards, obliquely and upwards bent to form first bending parts, the outside edges of the first bending parts are downwards bent to form second bending parts, and the lower surfaces of the second bending parts are inwards, obliquely and downwards bent to form third bending parts; the first bending parts, the second bending parts and the third bending parts form two edge beams; a bottom stringer is arranged at the bottom of a bottom plate, and a space is formed between the bottom stringer and the tail beam; the hinge seat is connected between the rear end of the bottom stringer and the tail beam and is positioned in the space; the front plate assembly is connected to the front end of the packing box body; a pull rod assembly is arranged at a position close to the rear end of the packing box body between the two side beams, and comprises pull rod seats fixed on the side beams and a pull rod connected between the two pull rod seats; the upper part of the rear dropside assembly is hinged to the pull rod seats. According to the packing box disclosed by the invention, the deformation of the packing box body can be reduced, and the mechanical performance and the force transmission performance of the packing box can be improved.

Description

technical field [0001] The present invention relates to dump trucks, in particular to dump truck cargo boxes. Background technique [0002] The dump truck container is used for loading and unloading goods. Traditional cargo boxes are heavy and have little cargo capacity. In order to solve the above-mentioned technical problems, there is a U-shaped container now. [0003] For example, a U-shaped cargo box of an off-highway dump truck is disclosed in a patent document with the Chinese patent application number 201220575349.4 and the application date being 2012.11.5 and the authorization announcement date being 2013.4.24. It is a coverless hollow box composed of a bottom plate, two side plates, a front plate and a rear plate. The bottoms of the two side plates are respectively bent four times in a row toward the center of gravity, each time at an angle of 165°, forming The arc-shaped connection of the side plates; the two sides of the bottom plate are bent upwards three time...
