AI Technical Summary
Existing forage cutting devices result in uneven cutting of forage during the cutting process, with some forage not being completely cut, leading to poor cutting results.
The system employs a double-layer cutting structure. The blades in the secondary cutting box initially cut the forage, while the blades in the main cutting box further cut it. The first and second blades prevent the forage from passing through the gaps, ensuring the uniformity and integrity of the forage during the cutting process.
It improves the uniformity and degree of forage cutting, ensuring uniform forage chopping and significantly improving the cutting effect.
