Embodiment Construction

[0026] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] Such as figure 1 , figure 2 , image 3 As shown, a dump truck box body includes a car body, and the car body includes a bottom plate 1 and two side plates 2, and the bottom plate 1 and the two side plates 2 form a tank structure, and the bottom plate 1 and the two side plates The inner surfaces of the side panels 2 are all covered with polymer liners 3 .

[0028] The polymer liner 3 is made of polyurethane layered coating, and at least includes a bottom layer bonded to the bottom plate 1 and the side plate 2 and a surface layer on the bottom layer and the bottom layer, and the surface layer is mixed with ceramic powder.

[0029] The mixing ratio of polyurethane and ceramic powder in the surface layer is: 1-3 parts by weight of pol...

Abstract

The invention discloses a dumper box body. The dumper box body comprises a carriage body, wherein the carriage body comprises a bottom plate and two side plates, the bottom plate and the two side plates form a groove structure, and macromolecule lining plates are laid on an inner surface of the bottom plate and inner surfaces of the two side plates. The dumper box body is advantaged in that the macromolecule lining plates formed by coating polyurethane in a layered mode is advantaged in that impact is well relieved, friction generated when goods slide out is reduced, the carriage body is effectively protected, moreover, polyurethane has high chemical corrosion resistance, and diversity of goods transported by the carriage can be improved, furthermore, the ceramic powder is mixed in a surface layer of the macromolecule lining plates combined with the bottom plate, so hardness can be effectively improved, and structural strength is improved.

Description

technical field [0001] The invention belongs to the field of dump truck boxes, in particular to a dump truck box body. Background technique [0002] A dump truck is a vehicle that unloads goods by itself through hydraulic or mechanical lifting. Also known as dump truck. It is composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device and other components. [0003] The compartment of a dump truck is divided into two types: backward tipping and sideways tipping. The movement of the piston rod is controlled by the operating system. Backward tipping is more common. [0004] The carriage will bear greater friction and impact when the cargo slides out, and is easily damaged during long-term use. How to protect the box and reduce its damage during use needs to be solved urgently. Contents of the invention [0005] The object of the present invention is to provide a dump truck box that overcomes the shortcomings in the prior art. F...
