Automatic unloading device for rear-turning cars

Abstract

The invention discloses an automatic unloading device for rear-tipping truck. The structure includes a hopper side rib, a hopper, a driving control cabin, a traction wheel, a driven wheel, a fuel tank, a chassis, and an automatic unloading device body. The top of the chassis is provided with an automatic unloading device body and the two are in interference fit. The top of the automatic unloadingdevice body is provided with a hopper and the two cooperate. The automatic unloading device body first controls the rotation of the rear-tipping circular shaft through an active mechanism provided inside the steel outer frame. As the rear turn round shaft drive and the rear limit position support rotates, the back end of the hopper first starts to receive force and drives the hopper to perform a certain degree of rear tipping. At this time, the active mechanism sequentially drives the screw hydraulic mechanism and the piston hydraulic mechanism to lift the piston rod on the hydraulic lifting cylinder upward. In order to realize the automatic unloading of the cargo after the hopper is rear tipped, the hydraulic lifting cylinder cooperates with the active mechanism, which enables the hoppersto form uniform force at both ends during the rear tipping process, and ensures the safety of unloading when the hopper is rear tipped.

Description

technical field [0001] The invention relates to the field of dump trucks, in particular to an automatic unloading device for a rear flip car. 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] In the prior art, the dump truck needs to turn the carriage back, and usually first controls the movement of the piston rod to realize the back turn of the carriage. This method is easy to damage the piston rod during the backturn of the carriage, which is not conducive to long-term use, because the force is exerted during the backturn of ...

Problems solved by technology

[0004] In the prior art, the dump truck needs to turn the carriage back, and usually first controls the movement of the piston rod to realize the back turn of the carriage. This method is easy to damage the piston rod during the backturn of the carriage, which is not conducive to long-term use, because the force is exerted during the backturn of the carriage. The point is generally at the angle between the carriage and the chassis, and the piston rod only provides upward thrust, which cannot guarantee that the support between the carriage and the chassis will not be broken due to uneven force during the backturning process of the carriage, causing the carriage to Slip and break the piston rod, causing an accident
