Abstract
A longitudinal axial flow drum structure having an adjustable threshing diameter includes a threshing drum, a transmission mechanism, a diameter regulating mechanism and a regulating steel wire pulling mechanism. The transmission mechanism delivers power to regulating devices of the diameter regulating mechanism. The diameter regulating mechanism is connected with the transmission mechanism and the threshing drum to enable threshing diameter regulation. The transmission mechanism and the diameter regulating mechanism are installed inside a feeding cylinder of the threshing drum. The threshing diameter is regulated in real-time and stepless manner by adjusting the regulating steel wire pulling mechanism to pull a regulating steel wire in the transmission mechanism.
