Description

Technical Field

[0001] The utility model relates to the technical field of dump trucks, in particular to a rear compartment opening mechanism of a dump truck. Background Art

[0002] Dump trucks refer to vehicles that unload goods by themselves through hydraulic or mechanical lifting. They are composed of automobile chassis, hydraulic lifting mechanism, cargo compartment and power take-off device. Dump trucks are divided into two types: backward tipping and sideways tipping. Nowadays, small trucks usually unload goods by opening the rear compartment. Small trucks are usually agricultural dump trucks, construction engineering vehicles, garbage dump trucks, etc. Since the loading compartment can automatically tip over to a certain angle to unload, it greatly saves unloading time and labor, shortens the transportation cycle, improves production efficiency, and reduces transportation costs. It is a commonly used special transportation vehicle. At present, in the operation of opening the rear compartment of the dump truck, in order to avoid the rear compartment door being affected by inertia during the transportation of the dump truck, it is necessary to open the rear compartment door. When opening, the trunk door will be fixed with a handle or locked, but in the process, relevant personnel are required to manually close the trunk door. However, in the process of closing the trunk door, a certain amount of physical strength is required, and the trunk doors that open on both sides need to be aligned to close the trunk door. When opening, a relevant person is required to open the trunk doors one by one, which is a relatively repetitive operation and consumes a certain amount of physical strength. Two relevant personnel are required, which is faster than one relevant person opening the trunk door, but increases the corresponding labor input, thereby reducing the efficiency of opening the trunk of the dump truck, and directly affecting the opening effect of the trunk of the dump truck.

[0003] Therefore, it is necessary to develop a dump truck trunk opening mechanism. Utility Model Content
