In the mechanized harvesting process of peanuts, the feeding system, as a key link connecting crops and subsequent processing devices, has an important impact on crop transportation stability, damage control and operation efficiency. However, due to the complex and changeable growth environment of peanut crops, including different terrain slopes, soil moisture, and differences in crop maturity and density, traditional fixed parameter feeding systems are difficult to adapt to these complex conditions, which can easily lead to crop accumulation, stagnation or damage, affecting harvesting efficiency and crop quality.
