SOLAR HEATING GRAIN VENTILATING AIR CHANNELS

摘要

The present invention relates to crop production drying equipment, air-heating solar collectors. Offered grain solar heating ventilating ducts made ??up of semi-circular folding segment (1) or telescopic cylindrical move out and move together segments (2), made ??of perforated metal and mounted close to the crop drying equipment fan (3) and are attached to it by a flexible connection (4). Air duct is to be mounted on a black solar energy absorbent material (5).
