Abstract
An improved tub chopper is disclosed having a speed sensing device which automatically slows the tub sidewall speed responsive to slugging or slowing of the chopping apparatus. A positive drive to the tub sidewall is provided by means of an economically constructed undulated band secured to the sidewall and operable through a plurality of rollers on a rotating wheel to drive the sidewall. The tub floor is configured with an upwardly convex, gradually tapering shape terminating in an adjustable wing extension for enhancing the movement of material in the tub into the chopping station. Novel chopping knife construction maximizes the effective life of the chopping knives. One knife embodiment presents six different available cutting surfaces and another embodiment involves disc shaped knives wherein the entire disc periphery is utilized for cutting material. The discs are continually rotated to change the portion of the cutting edge which is in material cutting position.
