Soil cultivator with driven rotors - has vertical rotors each with set of sprung steel tines (NL220377)

摘要

A ground working implement has a set of tined rotors (11) each with a vertical drive shaft (10) supported by a cross beam incorporating a box girder (2) supporting the driving gearwheels (14). On the bottom of each shaft (10) is the hub of an implement adaptor (21) of two superimposed plates in the corner of which are circular holes to take bearing-housings (30). An axle inside each bearing housing (30) parallel to the shaft (10) has a bracket on the end. Holes in the sides of the bracket are for fixing the sprung steel implements (40). End plates (42) on the chassis project backwards and forwards. At the front is bolted a backwards pointing arm (44) to which is attached a roller (45) around which are rods (48). At the back is bolted a forwards pointing arms (52) the front end of which slopes towards the ground.
