  • the invention relates to a device with which granular (granulated) spreading material is spread onto the surface in several sections simultaneously with several metering devices.
  • Numerous devices for spreading spreading material are known from the art, of which a number are also suitable for spreading granular spreading material with a grain size of approx. 0.2 mm onto the intended area with the aid of a spreading vehicle.
  • Mineral fertilizer or seeds can be used as spreading material. It is advantageous if the spreading vehicle can cover a wide spread at the same time.
  • a device which is advantageous compared to the previously known prior art for dispensing the spreading material described is known from WO 97/00 603 AI (Horsch). With this device, the spreading material is transported pneumatically via a compressed air drive via feed lines to the granulate outlets.
  • Each metering device has a plurality of driven cellular wheels or rollers, which convey the granulate from a storage container into the air flow of the pneumatic system. This device has the advantage over the known devices that the 2
  • Horsch device can be further improved. It turns out that, especially when applying fertilizer, a rapid change in the actual application rate is an essential parameter.
  • the object of the invention is to further increase the precision of the distribution at the individual fertilizer or granule outlets and the control bandwidth of the system.
  • each metering device has a plurality of output channels, each of which is assigned to its own fertilizer or granulate outlet.
  • the individual output channels are separated directly on the roller. This results in a larger control bandwidth.
  • An arrangement of a plurality of metering devices on a vehicle for application is advantageous, wherein these metering devices can be connected to a storage container. This enables an even larger control bandwidth.
  • the version in which the spreading material is conveyed through the rollers with the aid of atmospheric compensation - achieved by overpressure - is advantageous.
  • the reservoir is under the same pressure as the static pressure in the pneumatic conveyor.
  • the granulate then falls after being conveyed by gravity, but supported by the excess pressure from the storage container into the distribution lines and is carried on to the fertilizer or granule outlets by the compressed air drive.
  • This arrangement prevents part of the air flow from flowing through the distribution box into the storage container and thus impairing the filling of the rollers.
  • suction effects can be dispensed with at the point of feeding into the pneumatic line.
  • the exploitation of a Venturi effect at the point of introduction would require additional pneumatic power, the saving of which makes the system design easier.
  • rollers are cylindrical, the conveying process being carried out by circular segment-shaped incisions in the respective cylinder. If these incisions do not form parallel to the cylinder direction, but by a certain angle of 15 ° to 60 ° (preferably 40 ° to 45 °) to it (scissor arrangement), the conveying process is facilitated by a smooth running of the rollers and a jam of Spreading material and blocking of the rollers are more easily avoided.
  • the scissor arrangement of the conveyor cuts also promotes self-cleaning of the system.

  • rollers 20, 22, 24, 26 are arranged one behind the other.
  • the rollers are initially cylindrical and in the exemplary embodiment have a length of 101.8 mm and a diameter of 100 mm.
  • the rollers have incisions 30, 32, 34, 36 in the form of segments of a circle, in which the material to be conveyed is carried along when the rollers rotate. In the exemplary embodiment, these incisions are not made parallel to the longitudinal axis of the rollers 20, 22, 24, 26, but instead have a certain angle with it, in the exemplary embodiment 42.5 °.
  • the rollers are attached to a - in the exemplary embodiment hexagonal - conveyor shaft which is provided with a drive and which causes the rollers to rotate. in the 5
  • rollers 20, 22, 24, 26 belonging to a metering device are rotated together and at the same speed.

  • the feed device has four separate shafts 50, 52, 54, 56.
  • the shafts are separated from one another by dividing plates 62, 64 and 66 and are tapered towards the bottom. They continue in a tubular shape and end in T-shaped inlets in compressed air lines 70, 72, 74, 76, which on one side connect to the compressed air supply and on the other side - through correspondingly long lines or hoses to the fertilizer or granulate outlets are connected, with the vertical line of the T pointing upwards (inverted T).
  • the rollers 22, 24, 26, 28 are located in a housing which is formed on the two sides along the rollers by two plates.

  • the housing is also defined by plates through which the drive shaft of the rollers passes.
  • the housing is connected to a storage container.
  • the metering housing has a slot-shaped shaft which is provided with a sealing lip which seals against the housing and against the rollers.
  • the housing described above, in which the rollers 20, 22, 24, 26 are accommodated, is divided with separating plates, the separating plates 82, 84, 86 representing upper continuations of the separating plates 62, 64, 66 of the feed device 40. They can either be fastened vertically to the plates of the housing or actually extensions of the separating plates 62, 64, 66 of the feed device (lower separating plates) can be connected upwards and integrally with these.

In this case, it is also necessary to subdivide the sealing lips according to the number of cutting discs.

Abstract

L'invention concerne un dispositif d'épandage servant à projeter une matière à répandre granulaire, notamment de l'engrais, à largeur de bande de réglage importante et à commande directe. Ce dispositif comprend au moins un dispositif de dosage présentant au moins deux rouleaux, un dispositif d'entraînement des rouleaux, un boîtier logeant lesdits rouleaux, un arbre d'entrée pour les rouleaux correspondant au dispositif de dosage concerné et un dispositif d'alimentation (40), disposé en dessous du boîtier. Les rouleaux sont placés en rang les uns derrière les autres sur l'arbre d'entrée. Le dispositif comprend en outre au moins un convoyeur pneumatique comportant deux conduites d'alimentation pneumatiques (70, 72, 74, 76), servant à acheminer la matière à répandre, dosée par le dispositif de dosage, ainsi qu'au moins deux déversoirs pour la matière à répandre, raccordés aux conduites d'alimentation pneumatiques (70, 72, 74, 76). Les rouleaux disposés en rang sur un arbre d'entrée dans le boîtier et dont chacun correspond à un dispositif de dosage, sont séparés les uns des autres dans le sens axial par un premier élément de séparation. Le dispositif d'alimentation (40) est divisé en plusieurs entonnoirs par d'autres éléments de séparation (62, 64, 66), le nombre d'entonnoirs correspondant au nombre de rouleaux. Les premiers éléments de séparation et les autres (62, 64, 66), en fonction du nombre de rouleaux (20, 22, 24, 26) permettent de former au moins deux canaux séparés l'un de l'autre. De par la segmentation du flux de matière, ce dispositif convient à une répartition précise de la matière à répandre.
