Machine for pulling endives and other tap roots
First Claim
1. A mobile machine for uprooting endives and other tap roots, comprising a frame, an uprooting plowshare carried by said frame, a rotatable disc spaced transversely from said plowshare and located rearwardly of the plowshare in the direction of movement of the machine, a rotatable spoked wheel located along side said disc, motor means for driving said spoked wheel at a speed different from that of said disc and a tangential speed greater than the travelling speed of the machine, at least one of said discs and said spoked wheel being inclined in relation to the vertical to form a V, said disc and spoked wheel cooperating to lift and free from dirt said roots uprooted by said plowshare, and conveying means receiving said roots from said disc and spoked wheel.

PCT No. PCT/CH78/00028 Sec. 371 Date June 5, 1979 Sec. 102(e) Date June 5, 1979 PCT Filed Oct. 9, 1978 PCT Pub. No. WO79/00191 PCT Pub. Date Apr. 19, 1979
A mobile endive-harvesting machine has a fixed but position-adjustable uprooting plowshare and a spoked wheel disposed in front of a conveyor. The machine has an uprooting unit consisting of the spoked wheel which is driven at a speed greater than the travelling speed of the machine, and a disc disposed alongside the wheel and rearwardly and transversely spaced relative to the plowshare. The disc and spoked wheel define between them a vertical V.
