Dump truck and unloading method thereof

Abstract

The invention relates to a dump truck and an unloading method thereof. The dump truck comprises a truck head, an underpan and a long packing case arranged on the underpan, wherein the long packing case comprises a front packing case and a back packing case which are independently arranged; a front lifting hydraulic cylinder is arranged between the bottom of the front packing case and the underpan; the cylinder bottom end of the front lifting hydraulic cylinder is hinged to the underpan; the piston rod end of the front lifting hydraulic cylinder is hinged to the bottom of the front packing case; the left side or the right side of the front packing case is hinged to the underpan; the bottom of the front end of the back packing case is connected with the underpan through a back lifting mechanism; the back end of the back packing case is hinged to the chassis; a back door is arranged at the back end of the back packing case; a side door is arranged on the side, hinged to the underpan, of the front packing case. Through the adoption of the scheme, the dump truck is reasonable in structural design, and the long packing case adopts a separated structure to load and transport cargos separately, so that the stability of unloading is ensured, the tire burying can be avoided, and the unloading efficiency and the transportation efficiency can be improved.

Description

Technical field: [0001] The invention relates to a dump truck and its unloading method. Background technique: [0002] Currently used dump trucks have a separate section, and the goods cannot be shipped separately. There are currently two methods of unloading, one is rear unloading, and the other is side unloading. The rear unloading type is to directly lift the container so that the cargo flows down by itself. When the dump truck container is long (such as 9.6 meters), there will be two problems in the rear unloading type. Large, poor lifting stability, easy to overturn. Second, when lifting and unloading, because the rear overhang is too large, the tail of the cargo box is easy to touch the ground, which affects the lifting angle. It affects the working efficiency, and the side unloading type has the disadvantage of buried tires. Therefore, the problem of dump truck unloading of long cargo boxes has been puzzling people, seriously affecting unloading efficiency and tran...

The rear unloading type is to directly lift the container so that the cargo flows down by itself. When the dump truck container is long (such as 9.6 meters), there will be two problems in the rear unloading type. Large, poor lifting stability, easy to overturn. Second, when lifting and unloading, because the rear overhang is too large, the tail of the cargo box is easy to touch the ground, which affects the lifting angle.
