Abstract: The invention relates to a self-propelled harvesting machine comprising: —a removable harvesting unit (6) which can be mounted at the front in the direction of travel (F); —a processing unit in the interior; and —a harvested material conveyor channel (5) connecting said harvesting unit, when mounted, to the processing unit. According to the invention, the self-propelled harvesting machine is characterized in that a receiving space which at least partially receives said conveyor channel when in the harvesting mode can have its width adjusted transversely to the direction of travel.

Abstract: In general terms, embodiments of the present invention relate to methods and apparatuses for cleaning, grooming, and otherwise maintaining sand and sandy surfaces. For example, some embodiments of the present invention provide an apparatus for cleaning a sandy surface, where the sandy surface includes unsifted sand, and where the unsifted sand includes sand and unwanted material.

Abstract: Seaweed is picked up from the surface of a beach with general purpose earth moving machinery by installing a series of fingers extending forwardly and downwardly from the blade or bucket of the machine. By driving the machine forwardly along the beach, the fingers pass through the sand and seaweed on the beach travels up the incline of the fingers. The fingers accordingly act as a separator to separate most of the seaweed from most of the sand. Several embodiments of each moving machines are adapted for seaweed handling or removal.

Abstract: A harvester for root vegetables has a body, a pair of crawlers for supporting and moving the body, and an engine for driving the crawlers. A picker/conveyer device is longitudinally provided on the body and downwardly inclined for picking up root vegetables, and a stalk cutter device is provided under the picker/conveyer device at a rear portion thereof for cutting off a stalk from a root.

Abstract: A machine for removing strips laid out on the ground has a rotary reception unit for winding a strip at a distance from the ground to form a reel, and a driving unit for driving the reception unit for rotation. A drum is mounted so as to rotate. The strip passes over the drum before reaching the reception unit. Rotary brushes are arranged in such a way that the strip passes between the brushes and the drum so that the strip is brushed and the material from the ground accumulated on the strip is removed therefrom. The brushes are provided with a device for driving the brushes for rotation.

Abstract: A method and apparatus for disinfecting sand with an electrolysate of sea water, whose concentration of chlorine equivalent is 200-2000 mg/l before redepositing sifted sand back on to the beach.

Abstract: A machine for gathering oysters from an oyster bed, comprises a chassis (1) on which are carried a motor (2) and a gearbox (3). Two uprights (4) support endless treads (5) and the forward portion of the chassis supports an inclined frame (6) on which are mounted gathering members constituted by two adjacent circular flexible discs (7) each secured centrally to a rotatable axle (8). The discs are disposed above a fixed inclined comb (11) adapted to raise oysters sunk in the soil and/or distributed over this latter during movement of the machine so that the oysters will be seized during rotation of the discs (7) by flexible projections (10) arranged in star shape and projected rearwardly, the rotation of the axles (8) and the forward movement of the machine being obtained by drive belts connected to the gearbox.

Abstract: A machine for harvesting sugar-beets growing in rows in the soil is provided with a unit for loosening and lifting the sugar-beets, a cleaning unit for cleaning the sugar-beets from soil and stones, and an elevator for transferring the sugar-beets from the cleaning unit to an unloading conveyor positioned at a higher level than said cleaning unit and serving to unload the sugar-beets. The cleaning unit has a number of cleaning rolls having a core on which cleaning pins made of rubber or like material and projecting on either side are mounted, said cleaning pins having a flexural strength such that they do not damage the sides of the root-crops. Furthermore, the cleaning pins are so mounted on the associated cleaning roll that they are equally flexible in all directions. The cleaning unit also has an endless holding-down mat travelling around guide pulleys, the lower part of said holding-down mat exerting a load on the sugar-beets against the cleaning pins.

Abstract: A harvester for bulb, root and leafy vegetable products including stationary blades (31, 32), rotatable discs (131, 132) or the like which are transported at an angle through opposite sides of a product plant bed to loosen the soil, cut the root system, and prepare the products for removal from the plant bed; a pair of opposing, rotatable belts (51, 51') which follow an inclined path and cooperate to define a product passageway therebetween, said belts (51, 51') defining a product lifting and transport section (41) in which adjustable, pressure pulleys (48, 48') ensure proper gripping pressure on the products, and a product orienting section (42) in which the products are transformed from a vertical to a horizontal disposition; support means (70) adjacent said product orienting section (42) for receiving tops of products oriented to a horizontal disposition; and conveyor means (75) adjacent an end of said product passageway for receiving freed, horizontally disposed product.

Abstract: A peanuts harvester includes a truck body, plant row dividers, stalk straighteners, peanut diggers, a plant feeder, a tilted conveyer, a horizontal conveyer, a peanut stripper and a peanut collector such that the dug peanut plants are conveyed to the horizontal conveyer where the upper stalks are held by the conveyer and the lower peanuts on roots are stripped by the peanut stripper, whereby the stripped peanuts are screened, cleaned and collected into bags for efficient integrated harvesting of peanuts.

Abstract: A plant picking and boxing apparatus is mounted on a wheeled frame and includes an engine for driving the wheeled frame by a hydraulic system. Parallel mounted endless belts are supported on the frame and grip tomato plants, or the like planted in rows, and transport the plants into a loading mechanism. The plant roots are cleaned by rotatable, flexible flaps hitting the roots of the plants being transported between the parallel belts. The loading box has microswitch to determine when it is filled and ready for shifting to a second box, and to allow the plants to be pushed from the loading box into a packaging container where they can be placed on a conveyor and be conveyed to a closing platform on the wheeled frame.
