Abstract

PURPOSE: To prevent unsatisfactory shearing effect and to improve the rate of operation of a mill by setting the radii of rotation from tops of upper an lower blades, which are mounted on upper and lower rotary drums, to the center of each drum different and setting the angle speed of the rotating drum the same.
CONSTITUTION: A radius of rotation from the center 01 of an upper drum 2 of a drum type shear to the top of an upper blade 3 is set to be (r1), and a radius of rotation from the center 02 of a lower drum 4 to the top of a lower blade 5 is set to be (r2), and the radii of rotation is designed to be r1>r2, and the rotating angle speed θ of both upper and lower drums are set to be the same. When material 1 is fed in the direction shown by an arrow and the drum is turned in the direction shown by an arrow, the material 1 is pushed downward and bent when the upper blade 3 first touches the material 1, so that a bending angle of a crop becomes smaller and desirable shearing effect can be obtained in cooperation with the lower blade.
