A machine for collecting onion seeds

Abstract

The application belongs to the technical field of onion seed collecting equipment, and particularly relates to an onion seed collecting machine, which comprises a rack, an inflorescence collecting assembly and an onion seed collecting assembly. A walking wheel is rotatably arranged on one side of the rack. The inflorescence collecting assembly comprises a first guide rod, a second guide rod and a cutting mechanism. The first guide rod and the second guide rod are both suspended and arranged at intervals on the side of the rack away from the walking wheel and in the reverse direction of the moving direction of the rack. A converging guide gap is formed between the first guide rod and the second guide rod. The cutting mechanism is arranged between the guide gap. The onion seed collecting assembly comprises a collecting box, a rubbing roller and a driving mechanism. In the height direction, the collecting box is arranged on one side of the rack and below the guide gap and is provided with a collecting opening. The rubbing roller is rotatably arranged in the collecting box and is in transmission connection with the driving mechanism. The inflorescence collecting assembly gathers the dispersed onion stems and cuts off the inflorescences. The rubbing roller rubs the inflorescences entering the collecting box to achieve the purpose of taking out the onion seeds.
