Assembly for cleaning agricultural crops, using rotating brush rollers at a conveyor path, has individual vertical settings for the brush rollers with their motors separately or in groups

摘要

The assembly for cleaning agricultural crops has a number of powered rotating brush rollers (65) on a conveyor path. In the start position, all the rollers are on a common horizontal plane, and each can be adjusted vertically from the horizontal plane. The ends of the roller drive shafts (66) rotate in vertical setting profiles (2/1.2/3), which can be moved by spindle drives (25/1,25/3) vertically in the side walls of the machine frame, formed by upper and lower longitudinal profiles (46,47) with vertical guide profiles between them. The brush rollers are driven by motors (67), separately or in groups, and are controlled individually for their rotary speeds and direction of rotation.
