  • Patent number: 11553642
    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.

  • Publication number: 20180235143
    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.
