Abstract
A threshing device includes a threshing part with a rotatable unit which includes at least a flail and a concave which surrounds the rotatable unit. The concave is rotatably arranged in an opposite direction in relation to the rotatable unit. The threshing device includes a cleaning part with a rotatably mounted sieve, which surrounds the concave. A fan is arranged to provide an air stream towards the sieve for preventing the cleaned parts of the threshed material to pass through the sieve. The air stream is also arranged to transport out the cleaned parts which are collected in a space between the sieve and the concave.

A threshing device for threshing of a material, the threshing device comprising:
- a first rotatable unit which comprises at least a flail;
- a concave which is rotatably arranged in the threshing device and at least partly surrounds the rotatable unit;
- a rotatably mounted sieve, which surrounds the concave;
- and
- first transport means which is arranged to feed and transport grains in a substantially axial direction in a space between the first rotatable unit and the concave such that the grains are subjected to a threshing in a threshing gap formed between the flail of the first rotatable unit and the internal surfaces of the concave;
- and
- the threshing device comprising a fan which is arranged to provide an air stream which leads air in an at least partly radial direction inwardly towards the sieve.
