Cassava root harvester: to harvest cassava roots or tuber. It is mainly used for harvesting tuberous crops such as cassava. During operation, the digging shovel digs up the cassava and soil simultaneously, conveying them to the lifting chain. The lifting chain shakes the soil-cassava mixture backward, sifting the soil through the gaps between the rods. After separating the cassava tubers from the soil, they are laid bare on the soil surface and then collected manually. This method effectively reduces cassava breakage and soil adhesion.
