【正文】 plus rural labors to urban areas, the contradiction of each link of peanut production is more intensifying, the mechanization of the peanut production bees particularly important. It has been a long time for researching and developing the peanut harvesters in developed countries, it is a typical representative that the LP2 type peanut harvester and peanut bine harvester of Courtesy lf Lilli ston Mfg. Co. in the United States and PH2 type peanut harvester of Michigan in Netherlands. The development of peanut harvester in China is later than that in developed countries, perhaps the beginning of the 1960s. Since the 1970s, many representative mimic peanut harvesters were introduced into China such as the Dongfeng 69 type, 4HW800 type and 4H150 type peanut harvester products bring convenience for harvesting peanut, but the structure of all current harvesters adopted the two steps of harvest principle— scoop and separating chain bine together. These machines have to match with the mediumbig power tractors.

It is not suitable for the current requirement of peanut harvesting and results in that the harvesting of peanut is almost pleted by manual work at present. The mechanization level of peanut harvesting affected the development of the peanut production seriously. 2 Structure design of the peanut harvester Analysis of the whole machine structure 4H2 type peanut harvester bines with the advanced method of planting and agricultural requirement, which can harvest two rows at one working stroke. It matches with the ~ kW small fourwheel tractors. 4H2 type peanut harvester is posed of gaging wheel, transmission shaft, eccentric wheel, pitman, long rockerarm, erect axis, harve
