Description

TECHNICAL FIELD

[0001] The utility model relates to a truck self-unloading carriage auxiliary assembly field, concretely relates to a rear drive type linkage translation unloading driving device. BACKGROUND

[0002] The truck is usually provided with a carriage, and the goods are stored in the carriage during loading. The existing truck is simultaneously lifted by a hydraulic cylinder when unloading, so that the carriage is in an inclined state, and the material loaded in the carriage is slid out of the carriage. This unloading method is prone to cause the carriage to overturn during unloading, resulting in safety accidents. In order to improve the safety of the truck during unloading, the applicant has developed a translation self-unloading truck, which can quickly unload the material in the carriage in a horizontal state.

[0003] At present, in the specific design of the self-unloading carriage of the translation self-unloading truck, in order to ensure that the material in the carriage is completely unloaded, the shafts for unloading in the carriage have three sections, and the middle shaft moves first and the shafts on both sides move later during unloading. Therefore, the driving structure for driving the three shafts to move is not only complex, but also large in size and heavy in quality. With the adjustment of the truck load standard by the state, the approved load of the truck is greatly reduced, which leads to the three-section unloading device arranged at the tail of the carriage. Due to the heavy weight, it is easy to cause the vehicle to be in a dangerous state of the vehicle head being suspended when climbing, so the current design method of the driving mechanism using a single shaft driving is adopted. Specifically, a driving motor is installed at the bottom of the carriage to directly drive the main shaft, and then the squeegee moves to translate and unload the material in the carriage by the driving of the meshing transmission chain driven by the fixed sprocket on the main shaft. However, since a driving motor needs to be specially added at the bottom of the carriage to provide power for the translation unloading, not only the space at the bottom of the carriage is occupied, but also special pipelines need to be laid to meet the operation needs of the driving motor, which is not convenient for maintenance and has high cost.

[0004] Moreover, in terms of the size design of the self-unloading carriage, when the length of the self-unloading carriage is small, if the unloading main shaft is arranged at the tail position away from the head of the carriage to drive the sprocket and the transmission chain, a complex driving mechanism needs to be used to change direction multiple times to achieve the translation unloading, which further increases the design cost of the driving mechanism.
