Claim 0:
1. A material processing apparatus, comprising:
a machine body;
a conveyor belt for conveying material, the conveyor belt including a proximal end area adjacent a proximal free end of the conveyor belt and a distal end area adjacent a discharge end of the conveyor belt, the conveyor belt further including a central area between the proximal end area and the distal end area;
an actuating linkage providing a swivel connection of the proximal end area of the conveyor belt to the machine body such that the conveyor belt is movable between a folded-down working position and a folded-up transport position;
an actuator configured to move the conveyor belt between the folded-down working position and the folded-up transport position;
wherein the actuating linkage and the actuator are configured such that during swiveling motion of the conveyor belt from the folded-down working position to the folded-up transport position, the proximal free end of the conveyor belt is swiveled and raised against a direction of gravity; and
wherein the actuating linkage includes:
a first link swivel coupled to the proximal end area of the conveyor belt by a first swivel joint and to the machine body by a second swivel joint, wherein the first link has a first lever length between the first swivel joint and the second swivel joint;
a second link swivel coupled to the proximal end area of the conveyor belt by a third swivel joint and to the machine body by a fourth swivel joint, wherein the second link has a second lever length between the third swivel joint and the fourth swivel joint, the first lever length being longer than the second lever length;
wherein the first swivel joint and the third swivel joint have different distances from the free proximal end of the conveyor belt;
wherein the third swivel joint of the second link is coupled closer to the free proximal end of the conveyor belt than is the first swivel joint of the first link; and
wherein a ratio of the second lever length to the first lever length is in a range of from 1:2 to 1:3.
