Self-discharging goods case of side-turn bottom board

Abstract

The invention relates to a side-turning bottom plate self-unloading packing box, which comprises a plurality of box bodies. A hydraulic lifting cylinder (20) is arranged on the bottom surface of a lifting bottom plate (11); rotary hinged shafts (4) at the two sides of the box are used for hanging movable box plates (7); an automatic box opening mechanism (12) matching with a box-plate-locking hook (24) at the lower end of the movable box plate (7) is arranged on the movable-end edge beam (30) of the lifting bottom plate (11). A control system controls an air line (51) through a circuit (38), and controls a fuel line (54) and a hydraulic device. One side of the lifting bottom plate (11) is connected with a bottom frame (9) through a turning shaft (25) and forms a fixed end. The automatic box opening mechanism (12) is controlled by an automatic opening switch to release the box-plate-locking hook (24), then a lifting switch (57) is shifted to control the hydraulic lifting cylinder (20) to operate the movable end of the lifting bottom plate (11) to turn over toward the fixed end, so as to unload automatically. The materials are unloaded in one direction, is quick and safe, and the operation is convenient and flexible, therefore the unloading efficiency in transportation is improved.

Description

technical field [0001] The present invention relates to cargo boxes of trucks, in particular to cargo boxes of dump trucks. Background technique [0002] At present, most of the self-unloading containers of domestic freight vehicles are integral car structure, and the box body is integral. When unloading, the rear door is opened first, and then the whole container is lifted by the lifting device to dump the material. Due to the heavy weight of the cargo box, when it is fully loaded, the load of the cargo box is large, the center of gravity is high, the stability is poor, and the dumping center is prone to deviation, which may cause a rollover accident in severe cases. Shandong Linqing Xunli Special Automobile Co., Ltd. designed a patented product "a new type of dump truck box assembly" (patent number 200620084731X). The dump truck is equipped with a split lifting floor, which can only lift the bottom of the box. For unloading, it is not necessary to lift the entire box, whi...

AI Technical Summary

Problems solved by technology

This structure requires manual opening and closing of the compartment door lock, which must be operated by a special person. It is labor-intensive to open the compartment door under full load, and time-consuming to close the compartment door under no load. The structure of the hammer type compartment door lock is relatively complicated. Easy to be blocked by materials and fail

In particular, the switch of the compartment door lock and the lifting of the self-unloading flap do their own thing. If the self-unloading lifting mechanism is activated when the compartment door lock is not opened, it will cause a malfunction, poor safety and low efficiency.
