Technical Field

[0001] The utility model belongs to the technical field of flatbed truck compartments, and more specifically, particularly relates to a self-unloading compartment applied to a flatbed. Background Art

[0002] A flatbed dump truck is a dump truck with a large-capacity compartment. It is widely used in the construction industry and can transport various construction materials, such as sand, cement, bricks, etc. In addition, it can also be used to transport construction waste and waste. Existing flatbed dump trucks are generally composed of a front, a compartment, a chassis, and a hydraulic system that controls the dumping of the compartment.

[0003] Existing application number: CN201821901350.5, the utility model discloses a hydraulically driven mobile floor dump truck compartment, the mobile floor device is installed inside the compartment as the bottom surface of the compartment and is located on the frame floor assembly, the mobile floor device includes a moving plate, a guide plate, a connecting pipe, and a cylinder from top to bottom; a plurality of moving plates are arranged side by side along the front and rear direction of the compartment, and a guide plate is fixedly connected to the bottom of each moving plate for connecting with the connecting pipe; the plurality of moving plates are divided into multiple groups according to a certain interval rule, and the moving plates in the same group are connected to the same connecting pipe through the guide plate, and each connecting pipe is connected to one of the cylinder barrel and the cylinder rod of an oil cylinder through a pipe clamp; the other of the cylinder barrel and the cylinder rod of the oil cylinder is connected to the frame floor assembly, and the moving plate is driven to move forward through the reciprocating motion of the oil cylinder, thereby realizing the reciprocating motion of the entire mobile floor device. The hydraulic cylinder is used as the power device, and the operation is stable and the speed is steplessly adjusted.

[0004] Based on the above, fragmentary materials such as sand and gravel are mostly granular or powdery, which are not easy to stack flat. When using large machinery such as excavators and loaders to load them into the compartment of a dump flatbed truck, bulges are likely to appear, requiring workers to climb into the compartment to level these materials, which is inefficient and puts workers at risk of falling. In order to prevent sand and gravel from being blown up by the wind and causing dust during transportation, tarpaulins are often used to cover the top of the compartment. These tarpaulins will also pile up on one side of the compartment when not in use for a long time, and are easily eroded by sunlight, rain, dust, etc., causing them to become brittle and discolored, affecting their service life.
