Machine for granulating bulk rubbish or bulky refuse of any kind

Abstract

Abstract A MACHINE FOR COMMINUTING BULKY REFUSE OF ANY KIND. THE MACHINE INCLUDES A PAIR OF ROTARY SHAFTS WHICH ARE PARALLEL TO EACH OTHER AND WHICH ARE ADAPTED TO ROTATE IN OPPOSITE DIRECTIONS. EACH SHAFT HAS DISTRIBUTED THEREALONG A PLURALITY OF ROTARY CUTTERS FIXED TO THE SHAFT FOR ROTATION THEREWITH WITH THE ROTARY CUTTERS BEING SPACED FROM EACH OTHER ALONG THE SHAFT AND WITH EACH CUTTER HAVING A SINGLE TOOTH, THE TEETH OF THE CUTTERS DISTRUBUTED ALONG EACH SHAFT BEING ANGULARLY STAGGERED ABOUT THE AXIS OF EACH SHAFT. THE CUTTERS ON ONE SHAFT ARE ALIGNED WITH THE SPACES BETWEEN THE CUTTERS ON THE OTHER SHAFT AND EACH CUTTER HAS A CIRCULAR PORTION FIXED TO THE SHAFT AND THE SINGLE TOOTHE OF EACH CUTTER PROJECTS BEYOND THE CIRCULAR PORTION OF EACH CUTTER. THESE CIRCULAR PORTIONS OF THE CUTTERS ON THE PAIR OF SHAFTS HAVE PERIPHERIES SITUATED CLOSELY ADJACENT TO EACH OTHER SO THAT THE SINGLE CUTTING TEETH ON THE SEVERAL CUTTERS OF ONE SHAFT MOVE THROUGH THE SPACES BETWEEN THE CIRCULAR PORTION S OF THE CUTTERS ON THE OTHER SHAFT. THE ROTARY SHAFTS WITH THE CUTTERS THEREON ARE HOUSED WITHIN A TROUGH-SHAPED HOUSING CARRYING AN UPPER INLET THROUGH WHICH MATERIAL IS SUPPLIED TO THE CUTTERS, THIS HOUSING HAVING A LOWER OUTLET SITUATED BENEATH THE ROTARY CUTTERS AT A LOCATION ADJACENT TO THE SPACE THROUGH WHICH THE TEETH OF THE CUTTERS TURN DURING ROTATION OF THE SHAFTS. THIS LOWER OUTLET OF THE HOUSING CARRIES A STRUCTURE WHICH PREVENTS THE COMMINUTED MATERIAL FROM PASSING THROUGH THE OUTLET UNTIL THIS MATERIAL HAS BEEN REDUCED TO A GIVEN SIZE, AND THE CUTTING TEETH FUNCTION NOT ONLY TO COMMINUTE THE MATERIAL BUT ALSO TO REPEATEDLY RAISE IT FROM THE OUTLET AND REPEATEDLY ACT ON THE MATERIAL UNTIL IT HAS BEEN REDUCED TO THE SIZE REQUIRED TO PASS THROUGH THE OUTLET WHERE A SUITABLE COLLECTOR CAN BE PROVIDED TO RECEIVE THE COMMINUTED MATERIAL. THE SPACES ON EACH SHAFT BETWEEN THE SUCCESSIVE CUTTERS DISTRIBUTED THEREALONG ACCOMMODATES A STRUCTURE FOR CLEANING COMMINUTED MATERIAL OUT OF THESE SPACES DURING ROTATION OF THE SHAFTS AND THE CUTTERS THEREWITH.
