Peanut is planted in a large area in China. In the past, harvesting was completely manual, which was labor-intensive and inefficient. A normal labor force can harvest 0.5 mu according to working 8 hours a day, and with the help of harvesting tools such as plows, it can harvest 2-3 mu a day. The peanut harvester (patent number: 00253682.x) introduced before can complete the harvesting of peanuts.

However, its structure is very complicated, its cost is quite high, and it has no function of picking up the residue in the soil (its residue in the soil is still very large), which affects the use and popularization of this product. This patent skillfully integrates the functions of digging, peeling, screening, picking and collecting, and can complete all the harvesting of peanuts. In addition, the unique picking-up function (the picking-up rate is 99.8%) and peanut seedling collection function can collect peanut seedlings together intact (peanut seedlings are very good livestock feed). In addition, the machine can be matched with hand-towed, motorized three-wheeled, small four-wheeled and 50-type tractors, which greatly reduces the production cost.

China's peanut harvester is still in an immature stage. Because of the special growth characteristics of peanuts, it is necessary to rely on special professional mature equipment to harvest peanuts. At present, there is no machine to harvest peanuts as efficiently as the wheat combine harvester.
