Cleaning attachment for experimental field combine harvester - has multi-sieve aggregate with fan to blow air across surface of sieves.

摘要

The combine harvester is adapted for harvesting different sorts of plants and incorporates a multi-sieve aggregate. A flat sieve (8) presents a smooth upper surface to an upper adjustable sieve (7). The upper surfaces has lips bent downwards, and is made of V2A sheet steel. The fan (17) is driven at constant velocity regardless of the speed of the thresher, by a hydraulic motor fed from the harvester oil circuit. USE/ADVANTAGE - The cleaning attachment on a multi-sieve combine harvester rapidly adapts to different sorts of plants.
