Chaff cutter with rotor and swivelling tools - has axially extending counter-fillets to rotating tools, breaking wind flow and blowing back into inlet funnel.

摘要

The rotor comprises swivelably suspended smooth or toothed tools surrounded by a housing with an inlet and an outlet. The cover of the housing has obstacles braking the material flow. Such obstacles are formed as webs (6',7',8') which are vertically located on the housing cover, spaced in the rotary direction of the tools, so that adjacent webs form a pocket (9) with the housing cover (3). The webs extend into the work circuit of the rotating tools (2), and their edges are toothed. ADVANTAGE - Increased efficiency.
