Abstract: A distributing machine—spreading machine and/or sowing machine includes a container, receiving material to be distributed, supported by a support frame, an outlet opening on the base of the container, a metering element downstream of the outlet opening, a motor-driven metering slide displaceable relative to the outlet opening, and a distributing element downstream of the metering element, for distributing the material. For adjusting a speed of the metering slide, while providing a compact design, the metering slide of the metering element includes a threaded spindle that is mounted axially fixed and is driven in rotation by a motor rotary drive having an axially fixed output shaft. Along the threaded spindle, a spindle nut is guided that engages with the threaded spindle. The spindle nut is connected to the metering slide, or to a lever arm arrange thereon, to actuate the metering slide by rotation of the threaded spindle.

Abstract: An agricultural machine for dispensing material to be distributed, which agricultural machine comprises at least one metering element having a metering roller for metering the material to be distributed mounted in a metering housing and is rotatably driven. The metering roller has a plurality of metering wheel segments, each metering wheel segment of the metering roller is assigned a separate drive to drive the metering wheel segments independently of each other to ensure exact metering of the material to be distributed within finely subdivided partial widths of the agricultural machine. The drives of the metering wheel segments of the metering roller are arranged in the interior thereof, for example within a tubular hollow body, on which the metering wheel segments are mounted, such that the drives are ideally accommodated with protection from external influences and in a space-saving manner.

Abstract: A distribution machine, in the form of a spreader or a seed drill, includes a container carried by a support frame for receiving pulverent or particulate material to be distributed. An outlet opening is arranged on a floor of the container. A metering member is arranged downstream of the outlet opening. A ground distribution member is arranged downstream of the metering member. A displaceable part, such as a metering slide of the metering member or a device, adjusts the delivery point of the material to be distributed onto the distribution member. The displaceable part is operatively connected to, and actuated by, an output shaft of an electromotive rotary drive, a servomotor or a transmission output shaft of a transmission, arranged downstream of the electromotive rotary drive such that the exclusively rotational movement of the output shaft or of the transmission output shaft is transmissible to the displaceable part.

Abstract: A distributor includes two distributor disks, which are driven rotatably by a drive train, to be attached to a power take-off shaft of a traction unit or of a tractor. The drive train includes a central input shaft driving a cross shaft to drive distributor disks via a central gear. The distributor disks can be rotated at different speeds with a reducing gear with variable output speed, arranged downstream of the central gear. The reducing gear is configured as a mechanical coaxial transmission with an input shaft connected to the cross shaft and an output shaft arranged coaxially to the cross shaft. A speed reduction ratio is changed by an adjusting element between a normal position, with an input speed of the input shaft corresponding to the output speed of the output shaft, and a speed reduction position with the input speed not equal to the output speed.

Abstract: Method for controlling a device for changing the spreading ring sector of a disc spreader including a controllable metering device, a distributor disc arranged underneath the metering device and provided with thrower blades, and the device for changing the spreading ring sector of the granular material on the ground. Functional dependencies of a setting parameter of the device for changing the spreading ring sector on a throwing parameter are stored in a database of a control unit assigned to the device for adjusting the spreading ring sector, and a set point value of the throwing parameter or of the setting parameter corresponding thereto is input in the control unit. An actual value of the throwing parameter is determined using a sensor, arranged near to the circumference of the distributor disc, and the actual value of the throwing parameter is compared with the set point value thereof in the control unit.
