Multipurpose dump truck

Abstract

The invention discloses a multifunctional dumper, which is formed by a dumper chassis, a freight box, a vertical sliding post, a tail door, a tensioning cylinder, a hoisting cylinder, a chain, a chain wheel and the like; when the dumping of freight needs to be realized by lifting, the tensioning cylinder is started, a piston rod of the tensioning cylinder extends, and the chain moves rightwards; in the rightwards moving process of the chain, the tail door is firstly driven to be backwards overturned around a second hinge shaft to be in a horizontal state, then a sliding post locking mechanism is unlocked, and the vertical sliding post is driven to downwards slide to be level with the ground; when the dumping of freight needs to realized by inclining the freight box, firstly a lock catch between a tail door plate and a tail door frame is opened, the hoisting cylinder is started, the piston of the hoisting cylinder extends, and the freight box is pushed to be backwards overturned around a first hinge shaft to be in an inclined state; the unlocked tail door plate is rotated around a third hinge shaft under the action of dead weight, and is separated from the tail door frame, so freight can be conveniently dumped from the tail door frame. The dumping of the freight can be realized by both lifting and inclining the freight box.

Description

technical field [0001] The invention relates to the technical field of special vehicle structures, in particular to a multifunctional dump truck. Background technique [0002] Existing garbage trucks usually have a self-unloading function. For bulk garbage, a lifting cylinder is usually provided on the chassis of the vehicle, and an openable tailgate is provided at the rear of the cargo box, and the cargo box is pushed backwards through the lifting cylinder. Tilt, so that the bulk garbage in the cargo box can be dumped out through the tailgate; for barreled garbage, there is usually a lifting frame on the left, right or rear side of the car, and the barreled garbage can be manually moved to the lifting frame , and then the lifting cylinder pushes the lifting frame to move up and down, so as to realize the unloading of barreled garbage. Due to the complex structure of the driving device of the lifting frame and the large space occupation, there is not enough space at the rea...

AI Technical Summary

Problems solved by technology

Due to the complex structure of the driving device of the lifting frame and the large space occupation, there is not enough space at the rear and lower part of the container to satisfy the function of the container tilting backward, that is, after the garbage truck is loaded with the lifting frame, it is impossible to realize the backward tilting of the container function, in order to achieve the function of the cargo box tilting backward, it is impossible to load the lifting frame

Therefore, the existing garbage trucks have a single function, and are either only suitable for loading barreled garbage, or are only suitable for loading bulk garbage
