[0023] The driving component 61 is a servo motor device.

[0024] The rotating supports 7 and hydraulic telescopic rods 8 installed on the top of both sides of the outer surface of the support frame 1 can adjust the height and angle of the header according to actual working needs to adapt to different terrains and harvesting requirements. The connecting short shafts 9 installed at the bottom of both sides of the outer surface of the support frame 1 are used to connect the header and the tractor transport equipment to ensure the stability of the header during operation, which is the existing technology.

[0025] In this embodiment, the first mounting ring block 63, the first cutting gear 64, and the second mounting ring block 66 rotate with the rotating column 62.

[0026] The working principle of the header of the corn stalk silage harvester provided by this utility model is as follows: During operation, the drive unit 61 is started first, which drives the rotating column 62 to rotate.
