Abstract
878,492. Separating apparatus. RECKIE, J. M. May 4, 1959 [Feb. 4, 1958], No. 3690/58. Class 117. Root crops e.g. potatoes, are delivered by an elevator 10 to a grader 11 consisting of two parts 12 and 13 each of which comprises pairs of rollers 14, Fig. 5, of resilient material, rotatable about parallel 1 horizontal axes, and each roller has resilient ribs 15 which co-operate with the ribs of adjacent rollers to provide a number of rectangular openings 16. The openings in the part 12 are smaller than those in the part 13. Each roller 14 comprises a set of individual rollers mounted on a shaft 17 journalled in a frame 18, each shaft has a sprocket, and an endless chain drives all the shafts. Each roller is kept clean by a brush located below it. Two pairs of dirt removing rollers 20 with spines 22 Fig. 4 are located between the elevator and grader and are mounted eccentrically on shafts 21 which are also driven by the endless chain. When grading potatoes, chats fall through the part 12 to receptacle, and seed potatoes fall through the part 13 to a conveyer 24 which carries them to an inspection table 25 comprising rollers 26 similar to the cleaning roller 20. The table has a partition 27 and deflector 29 so that the seed potatoes are delivered to one side of the table and the ware potatoes, which pass over the part 13, are fed to the other side. The grading machine is supported on wheels having cranked axles whereby the slope of the grader may be adjusted. The elevator is hinged at 33 to the machine frame so that it can be swivelled to lie above the grader table. The inspection table 25 is also removably hinged to the frame so that it can be stored in a vertical position.
