Dumper for unloading material on two sides by lifting middle of bottom plate of carriage

Abstract

The invention provides a dumper for unloading a material on two sides by lifting the middle of a bottom plate of a carriage. The dumper comprises a bottom plate longitudinal beam, a left movable bottom plate, a right movable bottom plate, a left cover plate and a right cover plate which are positioned on left and right sides of the bottom plate longitudinal beam, and a lifting mechanism, wherein the lifting mechanism comprises an ejector rod which can freely stretch to lift, and is fixed on an auxiliary frame and positioned under the bottom plate longitudinal beam; the dumper is characterizedin that: a transverse beam which is transversely arranged in the left and right direction is fixed on the auxiliary frame; the left side of the left movable bottom plate and the right side of the right movable bottom plate are hinged with left and right sides of the transverse beam respectively; the right side of the left cover plate is hinged with the bottom plate longitudinal beam; the lower surface of the left cover plate is lapped with the upper surface of the left movable bottom plate; the left side of the right cover plate is hinged with the bottom plate longitudinal beam; the lower surface of the right cover plate is lapped with the upper surface of the right movable bottom plate; the top end of the ejector rod of the lifting mechanism is fixedly connected with the lower side face of the bottom plate longitudinal beam; the dumper also comprises a loading and unloading mechanism comprising one or more groups of structures of supporting arms, left side arms and right side arms which are arranged in the longitudinal direction and are in profile distribution; the supporting arms are positioned under the bottom plate longitudinal beam and the upper ends of the supporting arms are fixed on the lower side face of the bottom plate longitudinal beam; and the left ends of the left side arms are hinged with the right side of the left movable bottom plate.

Description

technical field [0001] The invention belongs to the category of freight vehicles, and in particular relates to a dump truck in which the middle part of the bottom plate of the carriage is lifted to discharge material on both sides. Background technique [0002] As a cargo transportation job, dump trucks are widely used due to their high degree of mechanization for unloading. However, the structure of the loading and unloading mechanism of the dump truck in the prior art is complex, easy to wear, and the power required for unloading is relatively large, resulting in increased manufacturing costs, use costs and maintenance costs of the dump truck. Contents of the invention [0003] In order to overcome the above-mentioned defects in the prior art, the present invention provides a dump truck with simple structure, durability and labor saving. [0004] Technical solutions: [0005] Disclosed is a dump truck for double-side discharge by lifting the middle part of the floor of...
