Anti-blocking fulcrum shaft conveying chain device

The invention discloses an anti-blocking fulcrum shaft conveying chain device, and belongs to the technical field of agricultural mechanical equipment. The device comprises more than one fulcrum shaftchain link, an anti-blocking mechanism and a conveying chain pin shaft, the conveying chain pin shaft is arranged inside the fulcrum shaft chain link, the anti-blocking mechanism is arranged on one fulcrum shaft chain link, the fulcrum shaft chain links are sequentially connected, and a closed-loop fulcrum shaft conveying chain is formed. The device is higher in practicability, the reasonable gapof the fulcrum shaft conveying chain is adjusted through the length of an outer chain plate according to harvesting of different rhizome plants, soil and rhizome plants can be effectively separated through the reasonable gap, and the harvesting rate is increased. According to the anti-blocking mechanism, when the fulcrum shaft conveying chain runs to the lower portion, the fulcrum shaft conveyingchain can be automatically
