1. Garden refuse shredding apparatus including:
- a housing defining a chamber having a refuse inlet for receiving garden refuse therethrough and a discharge outlet through which shredded refuse may be discharged;
a feed hopper in communication with said refuse inlet for directing refuse through said refuse inlet into said chamber;
a rotor mounted in said chamber, said rotor including a mounting plate connected to a drive shaft or hub and adapted to rotate therewith about an axis of rotation extending through said housing, and one or more chipper blades integral with or mounted to said mounting plate for rotation therewith, said mounting plate having an opening in front of the or each chipper blade through which shredded refuse may pass, and one or more macerating means integral with or mounted to said mounting plate for rotation therewith and adapted to macerate refuse fed into said chamber wherein said drive shaft or hub extends through a wall of said housing and said mounting plate is spaced from said wall and said drive shaft or hub between said wall and said mounting plate is enclosed by a shroud and said shroud abuts and is secured to said housing at one end and terminates adjacent said mounting plate at the other end and said one or more macerating means is adapted to pass in close proximity to said shroud as said rotor rotates;
fan means in fluid communication with said chamber for creating an outflow of air through said outlet; and
drive means operatively connected to said drive shaft or hub for causing said rotor to rotate.

Abstract
This invention provides garden refuse shredding apparatus (10) which has a chipping rotor (20) supported for rotation about a vertical shaft (31) in a chamber (11) which has a hopper (14) which feeds refuse to radially disposed elongate chipper blades (30) which span a major part of the rotor (28). Fan blades (44) are supported on the rotor for creating an airflow through the hopper (14) to assist feed to the chipping rotor and to assist discharge of shredded refuse from the outlet (45). The chipping rotor (20) is driven directly from the vertical output shaft (36) of an electric motor or a petrol engine (21).

31. Garden refuse shredding apparatus including:
-
a housing defining chamber having a refuse inlet for receiving garden refuse therethrough and a discharge outlet through which shredded refuse may be discharged;
a feed hopper in communication with said refuse inlet for directing refuse through said refuse inlet into said chamber;
a rotor mounted in said chamber, said rotor including a mounting plate connected to a drive shaft or hub extending through an upper wall of said housing and adapted to rotate therewith about a generally vertical axis of rotation extending through said housing, and one or more chipper blades integral with or mounted to said mounting plate for rotation therewith, said mounting plate having an opening in front of the or each chipper blade through which shredded refuse may pass, and one or more macerating means integral with or mounted to said mounting plate for rotation therewith and adapted to macerate refuse fed into said chamber, and fan means integral with or mounted to said mounting plate for creating an outflow of air through said outlet; and
drive means operatively connected to said drive shaft or hub for causing said rotor to rotate;
wherein said refuse inlet opens generally upwards from said upper wall, said feed hopper extends upwards from said refuse inlet, said one or more macerating means extends upwards from said mounting plate on the side proximal to said refuse inlet and said fan means extends downwards from said mounting plate on the side distal from said refuse inlet, and wherein said mounting plate is spaced from said upper wall and said drive shaft or hub between said upper wall and said mounting plate is enclosed by a shroud. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43)
