The invention relates to a self-propelled peanut combined harvester, aiming at effectively solving the problems of a peanut harvester that the harvesting efficiency is low, the net rate is low, fruits and leaves cannot be completely separated and seedling leaves cannot be recycled. The self-propelled peanut combined harvester is characterized in that a rack is provided with a first conveying device, a second conveying device, a third conveying device, an auger conveying and separating device, a vibration sieve and a fruit wind sieving and separating device, which are driven by an engine respectively; a positioning, soil crushing and feeding device is arranged at a feeding end of the first conveying device; a discharging end of the first conveying device is connected with the feeding end of the second conveying device; the discharging end of the second conveying device is connected with the feeding end of the third conveying device; the discharging end of the third conveying device is connected with the feeding end of the auger conveying and separating device; the discharging end of the auger conveying and separating device is connected with the feeding end of a seedling leaf collection box. The self-propelled peanut combined harvester is novel and unique in structure, easy to operate, good in sieving effect, high in working efficiency, high in net rate and wide in applicable range, the fruits and the leaves can be completely separated and the seedling leaves can be recycled as feed.
