The lotus root is the most familiar aquatic vegetable, and has good medicinal and edible values because of crisp taste and high nutritive value, and is favored by people. However, the difficulty of picking and digging lotus roots is high, the degree of mechanization is low, the picking problem always plagues vast lotus root farmers, and the development of the lotus root industry is restricted. At present, the lotus root is picked and dug manually or picked up manually by flushing silt with a water gun. The lotus roots can be dug only about 100-150 jin of lotus roots by one person manually, the labor intensity is high, the production efficiency is low, the supply quantity is always not in line with the market demand quantity, and the lotus roots are not timely harvested and can be rotten in sludge to cause waste; the lotus root harvesting machine products at home and abroad are few, equipment for mass production and popularization is not available temporarily, and the mechanized harvesting technology is seriously lagged. The lotus root planting in China is increasingly developed towards large-area planting, the current market demands cannot be met by completely relying on manual excavation, and the development of mechanized excavation meets the current trend.
Currently, the existing lotus root digging machines are generally divided into two types, one type is a ship-type lotus root digging machine, and the other type is a pontoon-type lotus root digging machine. Because of different regional planting environments in China and different machine operation environments, the regional differences can not promote the lotus root digging machines. Lotus root farmers still need a high applicability, low price, small equipment and convenient operation mechanical equipment to replace manual lotus root digging operation, so that the planting area can be increased, the harvesting efficiency can be improved, and the harvesting cost can be reduced.
