The utility model provides a chain-array transmitter for feeding material to fixed cylindrical bale binding apparatus, which is composed of a side plate, a grass inlet baffle plate, a transmission rod with a friction square iron, a transmission canvas, a fixed support, a chain, a chain wheel, an expansion shaft, an expansion wheel, an adjuster, a press device, and a power input chain wheel. The upper end of the chain array transmitter is fixed with the material inlet at the lower end of a cylindrical bale binding apparatus, the power input chain wheel of the chain array transmitter and the drum chain wheel of the cylindrical bale binding apparatus are synchronously driven by one chain, straw is fed into a baling room of the cylindrical bale biding apparatus via a transmission tube with the friction square iron and a canvas transmission band which are fixed on the transmission chain, to be pressed and packed, to support the transmission and storage of straws. The lower end of the chain array transmitter can be rotated upward of 90 degrees around a folding rotation shaft near the material inlet of the cylindrical bale binding apparatus to be folded, to support the transmission and storage of the utility model in idle state.
