[0003] With the improvement of economic development and the development of science and technology, agricultural machinery tends to be intelligent, automated and mechanized. However, due to the complexity of the harvesting process, high labor intensity and high initial investment costs, carrot harvesting currently relies mainly on manual methods, and only a few regions have begun to try semi-mechanized harvesting. However, semi-automatic harvesting machinery is often accompanied by problems such as high labor costs, high carrot damage rate and high energy consumption.
