[0002] Sorghum is an important economic crop in my country with a wide range of uses, including brewing, animal feed, direct consumption, and silage. my country's agricultural mechanization has developed rapidly in recent years, but there is an imbalance in its development. The machine harvesting rate of sorghum is far lower than that of field crops such as wheat and corn.

[0003] Existing sorghum harvester headers generally use a reel to feed the sorghum. As the reel rotates, sorghum stalks on the ears fall off, resulting in waste. Furthermore, the sorghum stalks are bent during feeding, making it difficult for the cutting mechanism to cut them. Utility Model Content

It is characterized by further including several dividers arranged side-by-side on the header, and a transmission mechanism located at the bottom of the dividers and connected to the drive mechanism for driving the dividers; a pulling channel for sorghum to pass through is formed between two adjacent dividers.

[0007] The divider includes a mounting plate on the cutting platform, two sets of sorghum pulling mechanisms on the mounting plate and connected to the transmission mechanism for pulling sorghum, and a dividing plate detachably connected to the mounting plate; the two sets of pulling mechanisms rotate in opposite directions.
