Description

Double dynamical pivot dumper

Technical Field

The invention relates to a transport vehicle, in particular to a double-power rotating shaft unloading vehicle.

Background

In order to prevent the skins of potatoes from being damaged due to rolling when the potatoes are unloaded automatically, the applicant discloses a bulk single-vehicle dump truck without a bottom plate in an early patent application with the publication number of CN108944617A, wherein a funnel-shaped structure with an angle larger than the repose angle of most bulk cargos is adopted for a side plate of the bulk single-vehicle dump truck, so that the cargos are unloaded thoroughly in the unloading process, the energy consumption is low, and the collision among the cargos is light. It is more desirable that the car not be funnel-shaped but have side panels that are flat like conventional car side panels to allow more cargo to be loaded, but still allow endless conveyor belt discharge. It is desirable to increase the width of the endless conveyor belt to cover the bottom as much as possible. Thus, a larger driving force is required, and a single hydraulic motor cannot meet the requirements, but the requirements can be met by increasing the size of the motor, but the motor is not economical. Also, since the endless belt is positioned between sprockets that drive it to rotate, the sprockets need to be located as close to the side plates as possible. And the shaft must be capable of being easily replaced and maintained.
