Used to remove peanut pods from vines and roots. In China, there are two types used according to the characteristics of different regions and varieties. One is a nail tooth drum and concave plate type, similar to the nail tooth drum threshing device (see grain combine harvester), except that the gap between the drum concave plate is larger, the drum speed is lower, the peanuts through the concave plate sieve leakage, the fan airflow to remove debris and fall into the fruit box, for the north by drying peanuts with vines. Another is to make the peanuts through the two relative rotation of the teeth of the nail drum gap dehiscence, off the pods fall to the vibrating screen, in the fan airflow with the removal of debris after falling into the fruit box, suitable for the southern clumps of trailing peanuts.
