TECHNOLOGY FOCUS - ENVIRONMENT - Preferred Device: The end sides of the scraper drum (1) are completely covered by shroudings (42), with extended shroudings (15) to the rear as far as the angled conveyor (3), and rear shrouding walls (43) closely against the paths of the scraping tools (14). Guide surfaces (16) are fitted to the side shroudings (15), at the ends towards the angled conveyor, as far as between the side covers (29) of the conveyor. The angled conveyor has conveyor belt (22) between the side covers. It has a lower shrouding (30) under the lower level of the belt. The lower level of the conveyor belt reaches a point directly behind the scraper drum, set at a height to catch the separated compost scraped up by the drum and spun at the upper level of the belt for removal. The scraper drum is aligned with the shaft of the lower belt deflection roller (27) or linked by a scraper drum drive (21), preferably a hydraulic motor. A dosing scraper shaft is horizontally over the scraper drum, at a gap, rotating in the opposite direction at a speed of preferably one third of the scraper drum speed. It is powered by a dedicated hydraulic motor, and has a height adjustment with a swing action at the machine frame (2) or the side shrouding. Its rotating circumference is at a gap of 20 - 100 cm from the circumference of the rotating scraper tools (14). The angled conveyor has a lower (23) and an upper (24) section, with a horizontal swing axis (25) parallel to the shaft of the lower belt deflection roller (27), so that the upper level (28) of the belt can be swung upwards for transport. The conveyor belt is in one piece through the lower and upper sections. A lateral conveyor (7) is at the upper end of the angled conveyor, which swings between a rest position (35) and a working position (36) at the conveyor ejection zone, and matches the conveyor width. A compost loosening unit (8) is at the ejection zone from the conveyor, mounted to the trailing section (41) of the machine frame (2). The loosening unit has a fin (37), directly in the conveyor ejection zone and especially at the upper section (24), longitudinally against the working direction (10) of the machine. It swings out with a fin carrier (38), on upper and lower supports (40) to swing on an upright axis (39). The fin (37) has a pointed wedge shape, with the thicker end downwards. The angled conveyor is bridged by the frame of the central driver's cab (6), forming a channel (18) for the conveyor over and to one side of it. The machine drive (5) is supported by a carrier frame (34) at the machine frame. The operation of the vehicle is controlled electrically while compost is being scraped up, to set the vehicle speed. A pressure sensor is in the hydraulic or mechanical transmission to the scraper drum which decelerates the drive through an overload signal if the loading on the drum or the main drive exceeds a threshold value. EXAMPLE - None given.
