<p>1310338 Compost turners H T COBEY 19 April 1971 [30 March 1970] 25448/71 Heading B1C A compost turner comprises a self-propelled articulated vehicle having a boom 20 from which depends by a universal coupling 45 a frame 30 which mounts an endless movable web having shredding elements and providing an upwardly and forwardly directed working face. The boom is pivoted at 21 and can be vertically adjusted by a hydraulic cylinder 23 and swing longitudinally on a turntable 24. The inclination of the web may be adjusted by cylinders 46, 47 so that material may be projected to one side of the moving apparatus. There may be a cooperating reversible spiked shredding drum 50 (see also Figs. 4-6, not shown) resiliently mounted and adjustable parallel to the web by means of hydraulic cylinders 76 (77); there may be combs (65) with slots (66) accommodating the drum spikes (53). Ejected material may be slowed by a restrictor plate 80 and elements 83 which may be plates hinged thereto and acted on by springs 84, or which may be of spring steel. A hinged plate 90 guides the material into contact with the web. The web and drum are driven by hydraulic motors. The web may have a backing plate (48) and may be of chains, cables or belts with cross-bars, or with a continuous sheet of fabric or woven mesh.</p> |
