The utility model provides a harvesting device of a combine harvester. A raking wheel, a first harvesting cutter device, a second harvesting cutter device and a raking spiral pushing-conveying device are arranged on a harvesting frame arranged at the front of a machine body. The raking wheel is used for raking stalks, the first harvesting cutter device is used for cutting off the stalks of harvested objects and the stalks of non-harvested objects in a separating mode and is arranged in a longitudinal posture mode, and the second harvesting cutter device is used for harvesting the stalks of the harvested objects and arranged in a transverse posture mode. The raking spiral pushing-conveying device is used for carrying the harvested stalks toward a feeding port. The harvesting device is further provided with a feeding device which is used for enabling the feeding port to be communicated with a threshing device arranged on the left side portion of the machine body. The harvesting device of the combine harvester is characterized in that a first shaft is arranged on the left side of the harvesting frame in a reciprocating rotating mode and drives the first harvesting cutter device and the second harvesting cutter device. According to the harvesting device of the combine harvester, the reciprocating rotating transmission shaft can be used for driving the first harvesting cutter device in longitudinal posture and the second harvesting cutter device in transverse posture so that the transmission structure can be simple and achieved cheaply.本發明提供一種泛用聯合收割機之收割裝置，其根據收穫狀態的變化能夠容易地變更設置在收割裝置(5)上的作業裝置的驅動速度。在收割裝置(5)上具備縱向姿勢的第一收割刀具裝置(80)、扒摟輪(61)、橫向姿勢的第二收割刀具裝置(50)、扒摟螺旋推運器(33)、以及供給裝置(20)，在供給裝置(20)的後部具備向該供給裝置(20)輸入驅動力的第一軸(26)，在供給裝置(20)的前部具備：向扒摟螺旋推運器(33)及扒摟輪(61)側輸出驅動力的第二軸(27)；以及向第二收割刀具裝置(50)及第一收割刀具裝置(80)側輸出驅動力的第三軸(28)，第一軸和第二軸及第三軸通過傳動用的鏈(12C)而連動。
