| Abstract | A
nominal
degree
optimum
angle ,
revolving- knife sugar cane basecutter of 440 mm
diameter, with four smooth- edged blades of twentyedge angle was laboratory- tested to determine the
combination of basecutter rotational speed, tilt
and blade oblique angle , the objective being to
minimize the cutting energy expended per unit field area of
cut cane.
An apparatus featuring a basecutter of fixed vertical
axis of rotation, driven b y a variable - speed electric motor,
a winch-drawn trolley running on rails to feed cane to the
basecutter at a pre - determined feeding velocity, and with
facility for alteration of blade oblique angle and cane tilt
angle was used. Measurement of torque on the basecutter
spindle and the component of force opposing feeding motion,
together with a knowledge of the basecutters rotational
speed, the feeding velocity and the basecutters nominal
diameter, enabled the computation of the energy expended in
cutting a unit "field" area of cane .
The results obtained indicated a tilt angle of about
27 degrees, an oblique angle of about 35 degrees and a
rotational speed of between 600 - 800 rpm <knife peripheral
velocity at the basecutters nominal diameter of between 14 -
1 8 m/ s) to be most suitable, with the feeding velocity being
0. 225 m/s. |
