Unmanned collaborative grain unloading transfer trolley and autonomous operation system thereof

The invention discloses an unmanned collaborative grain unloading transfer trolley and an autonomous operation system thereof, belongs to the technical field of agricultural machinery unmanned operation, and aims at starting from the actual requirements of grain production in China, especially in southern fields, to provide an unmanned grain unloading transfer trolley based on navigation path planning. The automatic grain unloading device can be matched with the harvester to achieve unmanned cooperative grain unloading, automatic transferring and automatic grain unloading, labor is liberated, meanwhile, the problem that the operation time of transferring and unloading of a traditional harvester is wasted is effectively solved, and the problem that the waiting time for field grain unloading after the harvester is full of grains due to insufficient conveying capacity of a grain conveying vehicle is effectively solved; the uninterrupted operation of the harvester is further guaranteed, the comprehensive operatio
