Novel mandulapalka harvester

The invention discloses a novel mandulapalka harvester which comprises a machine frame body, a traction frame, a rotary tillage harrow, a soil shoveling plate, a depthkeeping wheel, a moving wheel, a feeding screw, a sieve cage and a storage box. A transition plate and a primary sieving device which are connected end to end and arranged front and back are arranged on the portion, behind the soil shoveling plate, of the machine frame body. The feeding screw, the sieve cage, a fan, a secondary sieving device and the storage box are sequentially arranged on the portion, at the rear end of the primary sieving device, of the machine frame body from top to bottom. The novel mandulapalka harvester has the advantages that the primary sieving device, the sieve cage and the secondary sieving device are arranged, the mandulapalka is sorted and sieved step by step when conveyed from front to back and is sufficiently sieved in the harvesting process, resource waste is avoided, meanwhile, the harvested mandulapalka is high in net output rate and is directly bagged after being dried, and secondary separation and secondary operation do not need to be manually carried out; in addition, the fan blows out impurities in the mandulapalka when the sieve cage rotates, and therefore the net output rate is further improved.
