Abstract

The invention relates to a cargo unloading door open and close device using a control device controlling a 5 bar like system, whose change of location enabling the open or close of the down unloading discharge door. It mainly comprises the basic bar system, additive bar system and the control device. One end of the basic bar connects with the joint and installation base or chassis, freely oscillating of the joint at X and Y directions, the other end of the basic bar connecting with one end of the bent lever and crook lever, the other end of the bent lever and the crook lever connecting through joint, with the installation base or chassis formed fixed bar forming 5 bar discharge door and close mechanism.

Description

technical field [0001] The invention relates to the forming, feeding, opening or assembling of containers or receptacles related to packaging, in particular to the operation mode and structure of a drop-down unloading door, especially to a vehicle or other drop-down unloading door. The opening and closing method and structure, the international patent classification number is B65B43 / 00, can be widely used in the unloading doors of various unloading devices, such as railway wagons (hopper cars), unloading mining vehicles and various unloading devices. storage container. Background technique [0002] At present, many bulk containers are unloaded from the bottom, such as the hopper car of a railway wagon. The unloading door and the opening and closing mechanism of this vehicle are a kind of automatic unloading device for railway vehicles. Nowadays, the unloading doors of railway freight cars at home and abroad are generally installed on the bottom or side of the car body. The ...
