Patent number: 7104338Abstract: A sweeper chain support system for allowing efficient removal of debris between a sweeper chain and a digger chain. The sweeper chain support system includes a rear roller supporting a rear portion of a sweeper chain, a pair of rear arms attached to the rear roller in a pivoting manner, a front roller supporting a front portion of the sweeper chain, a pair of front arms attached to the front roller in a pivoting manner, and a link member connected between the front arms and the rear arms.

Patent number: 6068059Abstract: A ground-crop harvester for potatoes and the like has two unique control features that enhance the productivity of the device and the quality of the harvested ground-crop (e.g., less bruising). The harvester preferably includes an excavator arranged to scrape up a layer of soil and ground-crop and a primary conveyor configured to receive the soil and ground-crop scraped up by the excavator and to separate soil from the ground-crop. A downstream conveyor is arranged downstream of the primary conveyor (e.g., directly downstream therefrom or after a secondary conveyor and/or other conveyors) to receive the separated ground-crop. A primary conveyor adjustable speed drive mechanism is provided for the primary conveyor. A downstream conveyor adjustable speed drive mechanism is provided for the downstream conveyor. A speed measurer or sensor is provided for sensing the forward speed of the harvester and for emitting signals representative of the speed.

Patent number: 5197211Abstract: The vehicle is intended as a self-propelled utility model for beach cleaning. It has a vehicle frame which comprises at least one front and rear axle. A garbage pickup is disposed therebetween. The vehicle is to be a multi-purpose vehicle. The vehicle frame equipped with wheels consequently has a centric, rectangular opening between the front and the rear axle. The garbage pickup is adjustably mounted in this opening, namely from an operating position in which it contacts the ground to a ready position in which it is lifted from the ground. Seen in the direction of driving, a collecting receptacle for the picked up garbage is located behind the garbage pickup.Type: GrantFiled: September 12, 1991Date of Patent: March 30, 1993Assignee: Karl Kassbohrer Fahrzeugwerke GmbHInventor: Walter Haug

Patent number: 5069292Abstract: A method and related apparatus is provided for size reduction and separation of soil clods mixed with a root crop. The method includes the steps of feeding the mixture along an enclosed operative path, manipulating the mixture so as to change the shape of the conveyed mass and break up the soil clods sufficiently to reduce the size and separating the clods from the crop. The manipulation preferably takes the form of shifting the clods longitudinally and laterally with respect to each other. The operative path is preferably serpentine in shape with the clods/crop expanding along the outside of bends and contracting along the inside of bends. The serpentine path is oriented in a substantially vertical direction and may provide differential speeds along the boundaries of the path. The optimum mixture is approximately 50% soil clods at the entry end, with the range being between 35% and 65%.Type: GrantFiled: September 21, 1990Date of Patent: December 3, 1991Inventors: Henry A. Baker, Nathan L. Baker

Patent number: 4842076Abstract: A potato harvester comprises a screening conveyor belt following a lifting device, an elevator disposed after the screening conveyor belt, a haulm separating device and a stone separating device. The elevator is formed from a double conveyor having an internally rotating bar-type conveyor belt with narrow openings and an externally rotating bar-type conveyor belt with wide openings. The two conveyor belts rotate in the same direction and are guided parallel to one another at least in the region of the conveying run of the elevator. One bar-type conveyor belt is further equipped with transversely directed entrainment webs which divide the gap between the conveying runs of the two conveyors into conveying compartments.Type: GrantFiled: August 5, 1986Date of Patent: June 27, 1989Assignee: Franz Grumme Landmaschinenfabrik GmbH & Co.

Patent number: 4033099Abstract: 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.Type: GrantFiled: October 24, 1975Date of Patent: July 5, 1977Assignee: The Regents of the University of CaliforniaInventors: William C. Friedel, Jr., Thomas S. Bettencourt, Daniel L. Freeman
