Abstract: Systems and methods for separating harvested crop product from twigs, dirt, dust, and other debris. A disk to be used in a harvester includes a first segment and a second segment and is configured to cooperate with adjacent disks axially mounted on a common rotational shaft, and radially cooperate with disks mounted on a parallel rotational shaft. The disks are used in a roller assembly or a harvester, and gaps between cooperating disks remain effectively constant during operation.

Abstract: A root crop harvesting machine has a crop lifting device that has associated therewith downstream in the conveying direction an ascending first sorting stretch with substantially unchangeable working width. The crop is conveyed across a cleaning stretch to a collecting bunker, wherein a conveying run movable along the ascending sorting stretch is guided to a top drop zone where the conveyed material is transferred onto a downstream conveying stretch. The conveying run in the area of an upper unloading end interacts with at least one deflection conveying unit receiving the conveyed crop stream. This upper deflection conveying unit is provided with at least one separating device that, in working position, is moveable into a position of lateral projecting width so as to project at least on one side past the receiving width of the machine; from this position, it is returnable into a travel position for road travel.

Abstract: A separator is provided for use with a ditching machine to segregate rocks and coarse aggregates from the material excavated by the ditching machine s that the excavated material may be used as padding to protect the pipeline or other item positioned within the excavated trench. The separator comprises a plurality of rows of blades mounted on a rotatable drum. The spacing between adjacent blades within a row allows passage of the fine excavated material between the blades but prevents passage of the rocks and coarse aggregates. The rotating blades then deposit the rocks and coarse aggregates in a row beyond the row of fine material deposited along the trench.

Abstract: A vehicle for beach cleaning has a vehicle frame with at least one wheel axis disposed on it. Garbage is picked up from the beach by a vertically adjustable garbage pickup and delivered to a conveyor adjoining the garbage pickup and conveying the garbage taken to a collecting receptacle disposed at the rear end of the vehicle frame. A supply rotor is allocated to the pickup area of the garbage pickup.In order to improve the supply, the pickup and the transport of refuse and the separation of refuse and sand and the disposal of the pollutants, a swivel frame supporting the garbage pickup and the supply rotor is lowerably mounted on the vehicle frame for vertical adjustment, the supply rotor being mounted on the swivel frame pivotably across a swivel range comprising different operating conditions by means of links and being in particular counter-clockwise rotatable about an axis of rotation mounted on the links.

Abstract: An improvement is presented in an apparatus for processing soil for planting wherein a separator are provided for initially separating rocks and other large objects from soil prior to crushing thereof, the separator comprising a plurality of respectively upwardly and downwardly directed pins which cooperate in the removal of said rocks and other large objects from the soil. Also provided is a vertical rotatable power driven shaft centrally located in said apparatus wherein a plurality of radially extending arms are fixed thereto and are rotatable with the shaft. Some of said separating pins are fixed to the arms and some cooperating separating pins are fixed to a disc plate also mounted about said power driven shaft. A rotating plurality of discs crush said soil to reduce large particles and destroy weed seeds, insects, and larvae.

Abstract: 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, 1979A 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.

Abstract: A beach cleaning apparatus comprises a forward assembly operatively connected to a trailer member, the forward assembly having a body portion rollably supported on a pair of spaced wheels and adapted for connection to a towing vehicle. A vertical member rotatable about a vertical axis extends upwardly from the body portion and has a rearwardly extending lever arm assembly pivotably secured thereto for movement about a horizontal axis. A winch on the forward assembly is connected to the lever arm assembly for effecting pivotal movement thereof. The free ends of the lever arm assembly are connected to the forward end of the trailer member, which consists of a rectangular container having a bed which comprises an interchangeable screen member adjacent its forward end and an interchangeable ground engaging blade member extending outwardly of the forward end.
