Abstract: A distribution device for metering granular material, such as seeds, fertilizer, or the like. The seed drill coulters of this distribution device are supplied with grains from at least one grain storage hopper via respectively separate feed tubes, wherein each of these feed tubes is allocated a metering device and a sensor unit for detecting the grains located in the partial flow. Each sensor unit and each metering device are respectively connected in signaling terms with a central regulating device, which processes the quantities of grains detected in the feed tubes as well as the motor torques measured in the metering devices, and which regulates the grain distances for each metering device by varying the drive speeds of the drives under consideration of target values for the grain distances and/or of target values of a longitudinal distribution of the grains from single, multiple, or all metering devices.

Abstract: A metering unit for granular material includes a conveyor disk driven by a drive motor and rotating approximately concentrically to an inner cover surface of a housing. The conveyor disk has a recess for the reception of at least one grain to be separated via at least one revolution of the conveyor disk. In the interaction with a groove-shaped and/or slanted profile of the inner cover surface, the recess forms a conveyor pocket for conveying one grain or a plurality of grains in the direction toward an outlet opening extending approximately tangentially from the inner cover surface. For varying an axial distance to the inner cover surface and/or a width of the conveyor pocket, the conveyor disk, which is rotationally fixedly connected with the drive motor, is adjustable in the axial direction of the drive motor.

Abstract: Disclosed is a method for metering granular material, such as seeds, fertilizer, or the like. By way of the method, the granular material being carried and conveyed by an airflow is directed through a feed tube into a metering unit, and guided therein along an approximately circular arc path and tangentially directed into an outlet tube, which is adjacent to the metering unit. The airflow being guided through the outlet tube and carrying and conveying the granular material, which is being conveyed in approximately equal spacing, is conveyed and/or accelerated within the metering unit by means of at least one conveyor disk or fan disk, which is electromotively driven at a regulatable rotational speed and which rotates approximately concentrically within the metering unit. The drive speed is increased or reduced based on a detected torque of the electromotive drive of the at least one rotating conveyor disk or fan disk.

Abstract: Disclosed are a method for metering granular material, such as seeds, fertilizer, or the like, in particular within a distribution unit or sowing unit of a distribution machine or sowing machine as well as a corresponding metering apparatus. By way of the method, the granular material being carried and conveyed by an airflow and/or by its own kinetic energy is directed through a feed tube into a metering unit, where it is guided along an approximately circular arc path and tangentially directed into an outlet tube, which is adjacent to the metering unit and which runs, at least in a section, slightly curved. The granular material being approximately evenly spaced and/or evenly metered and conveyed in an outer area of the curved outlet tube is at least partially carried by the airflow being discharged and exiting the metering unit through the outlet tube.

Abstract: Disclosed is an independent wheel suspension (1) for a steerable wheel (37) having a motor (3). The motor is connected via a linear guide (5), which is movable in an approximately vertical direction (A), to a revolute joint (7) which produces a steering connection, pivotable about an at least approximately vertically running axis of rotation (B), to a vehicle frame (39). The linear guide (5) is coupled to a fluidic spring and/or damping element (9) which forms a load-bearing constituent part of the revolute joint (7).

Abstract: A seed meter has a housing forming a seed-holding supply chamber and an outlet chamber and a thin feed wheel rotatable in the housing about an axis and formed centered on the axis with an annular array of radially outwardly open and axially throughgoing seats each dimensioned to hold a respective seed. Structure in the housing is positioned to prevent seeds from moving radially outward from the respective seats in the supply chamber but not in the outlet chamber. A pressure differential is applied across the wheel to move seeds in the supply chamber into the seats so that the seeds are expelled from the seats in the outlet chamber. The seeds are fed, one at a time into a seed conduit and/or to a conveyor for transfer to the seed conduit or to the down pipes of the seed coulters.

Abstract: An agricultural machine has a movable rack (10) having at least one main wheel (16, 18), a hitch (12) which is arranged on the rack (10), a reservoir container (14) which is carried by the rack (10) and/or the hitch (12), and an agricultural implement (20) which is attached to the rack (10) at the rear in the direction of travel and has a plurality of rear support wheels (28). The machine is developed to the effect that the at least one main wheel (16, 18) is positively steered as a function of the pulling direction of a traction force which is exerted on the hitch (12). Such a machine is particularly compact and maneuverable even when the reservoir container is large.
