Abstract: 1,221,279. Rootcrop harvesters. R. BAILLY. 3 Dec., 1969 [7 March, 1969], No. 59006/69. Heading A1F. A combine beet harvester comprises a tractor pulled main frame 1 with at least one driven, rotating horizontal grid 22 positioned behind fixed shares 15 which scoops up raised beets, which are prevented from being thrown off by a peripheral deflector, and transfers them into a drum 30 driven to rotate about a lateral horizontal axis. The drum raises the beets on radial plates (49), Fig. 2 (not shown), and deposits them on an endless conveyer 50 at the centre of the drum 30 which carries the beets into an accompanying trailer. While a number of rows are being dug, adjoining rows are stripped of leaves by radial flexible, elastic blades 75 mounted on each of the driven horizontal axles 72, 73. Driven to counter rotate, these blades 75 force the stripped leaves into a screw auger 77 which carries them to the opposite side of the frame and deposits them in a swath on the field from which beets have been already raised. The main frame 1 is vertically adjustable on screw jacks 8 and each of the operations of leaf-stripping, digging and loading the beets via drive conveyers may be carried out separately or in combination by raising out of operation the respective mechanism. The leafstrippers are raised by adjusting the screw jacks 99, 97; the frames 12 carrying the shares are manually pivoted upwards on a pin (18), Fig. 5 (not shown), and propped by a spar; and the drum 30 may be pivoted out of operation about the axle 45 by operation of a hydraulic ram 46. When the drum is raised the grid deposits the raised beets, which are deflected by pivotable baffles (34, 33), Fig. 4 (not shown), into a line on the ground.
