The invention is for the transferral of mainly loose and formable material such as fertilizer or similar products for example for the scraping of such products out of manure gutters. One or more scrapers (20) are arranged in a frame (10) and rotational around a bearing (28). The scraper surrounds a wheel-shaped contact body (22 a, b) which in its outer surrounding restricting surface (25) is composed of grooves (23) in which a lock (16) clicks into. Upon movement in the direction of arrow A the contact body becomes fixed through the lock being caught between the groove's one restricting edge (27) and a stopper (30) whereby the scraper takes the position shown in fig. 1 whilst the equipment's movement in the direction of arrow B frees the lock (16) and allows the restricting body and therefore the scraper to rotate around its axle (32). The existing material which is on a surface is as a result scraped away by the scraper when the equipment moves in the direction of arrow A while the scrapers rotate when the equipment moves in the direction of arrow B. The rotation allows in the latter direction of movement the equipment to pass over the material that exists on the surface.<IMAGE> |
