Field cleaning fan - via rechargeable battery electrically operated device for the rapid screening of loss grains of a short straw - / chaff - / loss grain mixture

摘要

The field of cleaning fan for the separation of loss grains is thus characterized,1. that it consists of a tubular housing (height of about 45 cm, the inner diameter of about 18 cm; dimensions may vary) is made of metal or plastic2. that in a defined interval of approximately 17 cm below the upper edge (measure can vary) is a fine sieve with a mesh size of 0,5 – 1 mm (measure can vary) is installed, that fills the entire tube cross-section.3. that below the screen is mounted a battery-operated blower, the stream of air from below through the screen4. that the fan a fixed or variable speed can have5. that the accumulator by motor vehicle - charging cable or by means of a 220 v can be charged network adaptors.
