A semi-trailer container self-unloading equipment

Abstract

The invention relates to the field of a semitrailer, in particular to semitrailer container self-discharging equipment. The semitrailer container self-discharging equipment comprises a vehicle frame, a box body, a box pushing device, a box conveying device and a frame conveying device, wherein the box pushing device comprises a box propping hydraulic rod, a front pushing device and a back pushing device; the box conveying device comprises a front conveying device and a back conveying device; each of the front conveying device and the back conveying device comprises a main conveying frame, rotating shafts, a rotating frame, a rotating hydraulic rod, a connecting wheel hydraulic rod, a wheel frame, a spring and a box conveying wheel; the frame conveying device comprises rotating discs, a connecting shaft, a support frame, a frame conveying motor, a No.1 slide rod, a No.2 slide rod, a connecting rod and position limiting plates. The semitrailer container self-discharging equipment has the advantages that a container can automatically and horizontally leaves away from the semitrailer; the container can be automatically conveyed to a specified container placing region; the manual operation is not needed; the inclination of the container and the shaking of the semitrailer cannot be caused; a semitrailer body and cargos in the container can be effectively protected.

Description

technical field [0001] The invention relates to the field of semi-trailers, in particular to a self-unloading device for semi-trailer containers. Background technique [0002] Semi-trailers are widely used in our lives, and they also bring us a lot of convenience. Container transport semi-trailers are a special type of container that loads goods of various shapes and sizes into standard sizes before transportation. The box is convenient for water, land and air transport. It can realize loading and unloading, transportation mechanization and standardization. It is a major reform of traditional transportation methods and an important part of transportation modernization. This kind of special box is a container; the vehicle specially used to transport containers is a container transport semi-trailer.

Problems solved by technology

[0003] However, in the prior art, the semi-trailer often uses a hydraulic lifting device to unload the container. The side of the container near the driver's cab is lifted through the hydraulic jack, and then the hydraulic rod is stretched out to lift the container. The container is slowly placed on the ground from the rear of the semi-trailer; during the whole process, the container is in a tilted state, and when the container moves to the rear of the vehicle body, the chassis of the vehicle body is easy to shake, which in turn easily damages the items in the container, and It is easy to cause wear and tear on the semi-trailer; thus, it is urgent to improve the traditional semi-trailer unloading method
