a dump truck

Abstract

The invention provides a dumper, comprising a chassis, a cab and a cargo compartment. A folding top cover is arranged at the top of the cargo compartment and comprises a folding cover body and a travelling mechanism that drives the folding cover body to expand and fold; the travelling mechanism comprises a travelling block and a traction block that is positioned at the tail end of the folding cover body; the sidewall of the cargo compartment is provided with guide rails matched with the travelling mechanism. The dumper also comprises a water tank, a conveying water pipe, a water valve and a nozzle; the nozzle is arranged on the conveying block or the traction block. The dumper has the advantages that the nozzle on the travelling block or the traction block can slide along the guide rails on the sidewall of the cargo compartment along with the travelling block or the traction block when in constant connection with the water tank, the guide rails on two sides of the cargo compartment canbe washed at any time under the control of the water valve, and soil accumulation on the guide rails on the two sides of the cargo compartment can be prevented.

Description

technical field [0001] The invention relates to the technical field of engineering vehicles, in particular to a dump truck. Background technique [0002] Dump truck is a kind of transportation vehicle that can unload goods by itself. It has the characteristics of automatic unloading and strong mobility, which can improve the efficiency of cargo loading and unloading, save labor and time costs, and has become one of the most important vehicles for cargo transportation today. It has been used in Widely used in urban construction, highway construction, water conservancy engineering and energy industry and other industries. [0003] In the existing structure, the dump truck generally includes a chassis, a driver's cab arranged at the front of the chassis, and a cargo box arranged at the rear of the chassis. The unfolded and folded traveling mechanism includes a traveling block and a traction block located at the end of the folding top cover. The side wall of the cargo box is pr...

AI Technical Summary

Problems solved by technology

Among them, the traction block usually includes a guide pulley block, symmetrically arranged up and down, a bent plate supporting the tarpaulin rod, and a walking wheel on the wing surface of the side plate reinforcement beam of the cargo compartment. The walking wheel is an ordinary roller with a fixed walking direction. During the soiling process, the upper wing surface of the dump truck’s reinforced beam is easy to accumulate soil. For example, the upper wing surface of the cargo box reinforced beam (reinforced beam guide rail) is easy to accumulate soil dropped from the excavator. It has adverse effects on the road surface and the environment, affects the sanitation of the road environment, and does not meet the requirements of environmentally friendly dump trucks. Manually cleaning the soil on the upper wing surface of the side plate of the cargo box to strengthen the beam will undoubtedly increase the labor cost
