ABSTRACT:
A roller adjustment apparatus provides for the independent adjustment of spacing between any two adjacent rigidly spaced apart rollers without affecting the spacing of any of the other rollers in a roller screen conveyor. A support block of the apparatus, which rotatably supports an end of the roller and is slidably mounted on the conveyor frame, has two oppositely extending threaded bores oriented normal to the axis of rotation of the roller and parallel to the longitudinal axis of the conveyor. A threaded adjusting bolt, having oppositely threaded ends, is placed intermediate adjacent support blocks and engages the confronting threaded bores therein such that rotation of the adjusting bolt either increases or decreases the spacing between adjacent rollers. Threaded studs and a threaded adjusting sleeve are alternate corresponding forms for adjusting the roller spacing. In one embodiment a support block having grooves along its top and bottom surfaces is slidably mounted between two support rails which are attached to the conveyor frame and engage the grooves. During spacing adjustment, the rails allow the other rollers attached to the opposite sides of the rollers undergoing adjustment to be either pushed or pulled thereon without affecting the spacing between any of these other rollers.
