<p>Device for sweeper units of the type which comprises an elevator in the shape of an inclined chute (16, 18). Carriers or brooms (28) which run in an endless path, are at one end of the path in contact with the ground surface which is to be cleaned, and transport refuses and the like upwards along the bottom (16) of the chute from the lower transverse edge of the chute. An interspace which exists between the lower transverse edge of the chute and the ground surface is, according to the invention, bridged over thereby that an endless, flexible sheeting (40) passes over, and substantially covers, the bottom (16) of the chute. After the passage over the bottom of the chute, the sheeting runs downwards ahead of the chute viewed in the direction of travel (22) or the sweeper unit (10) and contacts said ground surface (20), whereby said interspace between the lower transverse edge of the chute and the ground surface is bridged over by said sheeting (40).</p> |
