Abstract: Waste scattered on a sandy beach is recovered in a clean and efficient manner by using a beach cleaner of a simple structure. In a first waste recovery step, a first beach cleaner A is allowed to travel on a sandy beach while being towed by a self-traveling vehicle R, whereby waste G1 such as string-like waste and other elongated waste is caught on rakes and conveyed to a waste recovery area. In a waste recovery station the first beach cleaner A is lifted to recover the waste. In a second waste recovery step, while a second beach cleaner is allowed to travel by the self-traveling vehicle, waste such as cans which have not been recovered in the first waste recovery step are scooped up in a waste conveying section, and are then collected in a waste collecting section by means of scraping blades and are recovered in a waste recovering area.

Abstract: A harvesting device for separating round root crops, such as potatoes, from soil and other unwanted material. The crop and the soil in which it is growing is uplifted into the harvesting device by the forward movement of the device. The uplifted material is delivered into two conveyors, one positioned above the other and one running at a different speed from the other. The upper conveyor has a series of transverse members, such as fingers and flaps, which break up the uplifted material into discrete portions and these transverse members form with the lower conveyor a series of pockets so that each discrete portion of uplifted material lies in a pocket. The conveyors are inclined and this combined with the differential speed causes the material to be tumbled and the round root crops to roll free of unwanted material.

Abstract: A known and commercially available electronic sorter is positioned between the sorting conveyor of a tomato harvester and the front cross-conveyor thereof. This sorter includes a rejector mechanism for rejecting tomatoes of colors other than those corresponding to red-ripeness. A rejection chute receives culls impelled thereinto by the rejector mechanism dropping the rejected fruit on the ground, while accepted fruit falls to a front cross-conveyor. A preparatory mechanism associated with the sorting conveyor impels the tomatoes at a desired trajectory toward the electronic sorter, and preferably includes an elevating flighted conveyor for receiving tomatoes from the sorting conveyor, raising them to a higher level, and then dropping them forwardly on to an intermediate generally level conveyor. The intermediate conveyor is driven at a constant speed regardless of the speeds of all other moving parts of said harvester.
