【正文】 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 only plex in structure, higher manufacturing costs, more power consumption, poor reliability, but also higher harvesting loss rate, peanut vines spread disorderly, and inconvenient for manual collection. 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, harvesting parts, long pitman, rockerarm, mounting device and frame etc. The figure 2 shows its structure. wheel coupling shaft rockerarm pitman device axis part part Diagram of peanut harvester The driving power needed of the work parts of 4H2 type peanut harvester es from the PTO of tractor. When the machine with tractor goes forward, the PTO drives eccentric wheel 11 pass through joint coupling 2 and transmission shaft 3. Then eccentric wheel 11 drives long rockerarm 5 to move pass through pitman 12. As erect axis 4 and harvest parts 13 are made together, rocker 8 with long pitman 6 and long rockerarm 5 constitute an inverse paralle
