The utility model relates to the technical field of agricultural equipment, in particular to a front-end goods receiving device of an onion harvester. The front-end goods receiving device comprises a rack, rack cover plates are installed on the inner side of the rack in a bilateral symmetry mode, a harvesting mechanism is fixedly installed on the front side between the rack cover plates, and a screening and conveying mechanism is fixedly installed on the rear side between the rack cover plates. When the collecting device is used, the speed reducer enables the first double-gear assembly to rotate, the first double-gear assembly drives the first gear to rotate through the first chain, then the collecting device operates, meanwhile, the first double-gear assembly drives the second double-gear assembly to rotate through the second chain, and the first cross rod rotates to drive the fourth gear to rotate. The fourth chain drives the third gear to complete rotation to complete onion harvesting and transportation, t
