  • Material distribution systems of modern Agricultural spreading machines can be designed as so-called nursing systems, in which a main distribution unit is used to generate several conveying air flows loaded with spreading material. The conveying air flows are then fed to several material receiving units of the dispensing machine, whereby the material receiving units can each be assigned to a dosing system or be part of a dosing system.
  • the application material accepted via the material acceptance units is then dosed in dosing systems so that the dosed application material can be placed on the agricultural area via storage devices.

  • the control device can be set up to set a first pressure difference between the conveying air pressure and the metering air pressure in a first operating situation during the dispensing process and to set a second pressure difference between the conveying air pressure and the metering air pressure in a second operating situation during the dispensing process.
  • the metering air pressure serves as a reference variable in the several operating modes.
  • the metering air pressure can change for various reasons P22-047 change during the application process, for example because energy needs to be saved, because temporary changes in the application material are detected or because the dosing systems of the material distribution system should be emptied.
  • the metering air pressure can be specified by operator input.
  • the control device can determine a default value for a metering air pressure to be maintained.
  • different mode-specific pressure differences between the dosing air pressure and the conveying air pressure can be advantageous.
  • several mode-specific pressure differences are assigned to a distribution product and/or a distribution product type.

  • the material distribution system according to the invention can be operated in a continuous operating mode, in which the dosing systems are supplied with application material from the main distribution unit, and in an emptying mode, in which the supply of application material to the dosing systems from the main distribution unit is reduced or interrupted in comparison to the continuous operation mode .

  • the emptying mode the delivery of the application material from the main distribution unit to the dosing systems is reduced or interrupted, for example due to a completely emptied storage container or due to a flow-related interruption in the delivery of the application material from the main distribution unit to the dosing systems.
  • the material distribution system has at least one conveying air pressure sensor, which is set up to determine the conveying air pressure.
  • the conveying air pressure sensor can be arranged in front of the main distribution unit or behind the main distribution unit in the flow direction of the conveying air.
  • the conveying air pressure sensor can also be arranged in the main distribution unit.
  • the material distribution system can include several conveying air pressure sensors, for example two conveying air pressure sensors, whereby the determined conveying air pressure can be an average of the sensor values of the conveying air pressure sensors.
  • the conveying air pressure can be monitored by the control device or taken into account as part of a control routine when setting the conveying air pressure.
  • the material distribution system can also have at least one metering air pressure sensor, which is set up to determine the metering air pressure.
  • the dosing air pressure sensor is preferably arranged in front of the dosing system in the flow direction of the dosing air.
  • the dosing air pressure sensor can also be arranged in a dosing system.
  • the dosing air pressure sensor can also be arranged behind the dosing system in the direction of flow of the dosing air.
  • the material distribution system can include a plurality of dosing air pressure sensors, for example two dosing air pressure sensors, whereby the determined dosing air pressure can be an average of the sensor values of the dosing air pressure sensors.
  • the material acceptance units are preferably set up to cause the conveying air to the respective dosing system to be interrupted when a specific level of temporarily stored application material is reached.
  • a material distribution system according to the invention is also advantageous in which the one or more fans have a conveying air blower for generating the conveying air, the control device being set up to control the conveying air blower for adjusting the conveying air pressure as a function of the metering air pressure.
  • the control device is preferably set up to adjust the conveying air pressure via the fan speed of the conveying air blower.
  • the delivery air pressure can also be adjusted via one or more air pressure control valves between the delivery fan and the main distribution unit or in the main distribution unit.
  • the conveying air pressure can also be adjusted by setting the maximum supply air quantity on the conveying air blower, for example by adjusting the opening status of a supply air opening.
  • the opening state of the supply air opening can be adjusted, for example, by means of one or more diaphragm bodies, such as slats.

  • the operating modes of the material distribution system can be assigned to a fill level or a fill level range of output material in the main distribution unit.
  • the control device therefore ensures an adjustment of the pressure difference to be maintained between the conveying air pressure and the metering air pressure when the level of application material in the main distribution unit drops below the critical level.
  • the level sensor can be an empty indicator.

  • a small pressure difference is set between the dosing air pressure and the conveying air pressure, so that the conveying air pressure is reduced. In this way, it is avoided that P22-047 is temporarily stored in the material receiving units of the dosing systems Spreading material is pressed into the separating devices, as a result of which the separating would be interrupted or impaired due to a blockage of the separating device.
  • the spreading machine can be designed as a trailed or carried machine.
