Abstract

A sorghum cutting header and a sorghum harvester with large feed volume and multiple reeling pans includes a reeling header, a rod crushing device, and a reciprocating cutter device. The rod crushing device is located under the reeling header. The reeling header includes reeling pans, frame rods, bearing seats, reeling pan shafts, tandem shafts, and tandem shaft bearing seats. The reeling pan shafts are installed in parallel on the frame rod through bearing seats. The adjacent reeling pan shafts are in transmission connection, and at least one reeling pan shaft is in transmission connection with the power device. An inner part of any reeling pan shaft penetrates the tandem shafts. Both ends of the tandem shafts are supported on the frame rods, and one end of the tandem shafts is fixed on the tandem shaft bearing seats. The reeling pans are mounted on any reeling pan shaft.
