System for bringing a cover over, either removing it from silage present in a silo

摘要

System for bringing a reusable cover (13) over, either removing it from silage, in which use is made of an U-shaped silo (1) in which said silage is stored. Said system comprises a carriage (5) with wheels (6) which is motoric movable over the upper rims (4) of the upstanding walls (3) of said silo (1) and is provided with means (11,15) for rotatably supporting a motoric driven spool (12) on which said cover (13) can be present. Longitudinally extending hoses (16) are connected to said cover (13) which in pressed flat condition can be spooled onto said spool (12) together with said cover (13) and when said cover is unspooled can be filled with liquid. In particular along both the longitudinal rims (17) of said cover (13) hoses (16) are present which by bringing liquid into them are pressed against the walls (3) of said silo (1) over the total length of said cover (13).
