  • One of the tasks to be solved is to specify an improved lateral distribution device and an improved spreading machine.
  • the transverse distribution device is a transverse distribution device for a spreading machine and is designed to distribute spreading material fed by a feed device transversely to a feed direction.
  • the transverse distribution device comprises at least a first conveying device and at least a second conveying device for distributing the spreading material.
  • the first conveying device and the second conveying device have a first offset from each other in a first direction, wherein the first direction is perpendicular to the feed direction and perpendicular to a principal extension direction of the first and/or second conveying device.
  • the principal extension directions of the first and second conveying devices are preferably transverse, and more preferably perpendicular, to the feed direction.
  • the feed mechanism guides the spreading material from a storage container to the transverse distribution device.
  • the feed mechanism includes, for example, a feed chain.
  • the lateral distribution device is, for example, part of a spreading machine.
  • the lateral distribution device is preferably attached to an opening through which the spreading material is applied to a surface. From the perspective of the surface, the lateral distribution device is, in particular, mounted above the opening.
  • Lateral distribution devices are typically used in spreading machines to mix and homogenize a spreading material before it is applied to a surface. This is particularly necessary when the spreading material is to be applied to the surface through multiple openings in one discharge direction. To ensure the most uniform material flow possible through all openings, it is therefore necessary to distribute the spreading material evenly.
  • conveying devices such as screw conveyors
  • the axes of rotation of the conveying devices are arranged in a plane as close as possible to the bottom of the container.
  • a disadvantage of this method is that circulation is only achieved in the bottom area, resulting in only a quasi-two-dimensional mixing at the bottom of the container.
  • the transverse distribution device described here utilizes the concept of arranging conveying units offset from one another such that the conveying units have an offset perpendicular to the feed direction.
  • the conveying units have the first offset in a first direction parallel to the discharge direction of the spreading material.
  • the spreading material can be more homogenized by the transverse distribution device and, if necessary, distributed across several openings. Overall, this enables a more uniform material flow through the openings and consequently achieves a more controlled and uniform application of the spreading material.
  • the density of the spreading material can typically vary depending on the environmental conditions within the container. This means, in particular, that the density distribution of the spreading material can be heterogeneous. Such heterogeneity of the spreading material is typically undesirable, as it makes uniform distribution of the material more difficult.
  • the transverse distribution device described here advantageously achieves improved mixing of the spreading material in the area around the device and reduces heterogeneity.
  • the first conveying device is designed to convey spreading material brought by the feed device transversely, in particular outwards to the feed direction. to move.
  • the second conveying device is designed to move spreading material moved outwards by the first conveying device transversely, in particular perpendicular to the feed direction inwards.
  • the first conveying device is configured to move spreading material transversely or perpendicularly to the feed direction from a central area of the transverse distribution device or a container with the transverse distribution device outwards.

  • An "inward” movement describes, in particular, a movement from the peripheral area to the central area. In other words, an “inward” movement describes a movement inward with respect to a central axis of the feed direction.
  • An “outward” movement describes, in particular, a movement from the central area to the peripheral area. In other words, an "outward” movement describes a movement outward with respect to a central axis of the feed direction.
  • the conveying devices thus enable the movement of the conveyed spreading material in directions perpendicular to the feed direction during operation.
  • the second conveying device carries spreading material that was previously transported by the first.
  • the conveying device which was led outwards, then back inwards. This allows for a comparatively high homogenization of the spreading material in an area around the transverse distribution device, for example a container with the transverse distribution device.
  • the transverse distribution device has at least one second conveying device
  • the second conveying device is designed to move excess spreading material moved outwards inwards transversely to the feed direction.
  • excess spreading material is moved from the outer area inwards, i.e., towards the central area, by means of the second conveying device.
  • Excess spreading material refers specifically to spreading material that, after being moved outwards by the first conveying device, has not yet been applied to the surface. For example, excess spreading material remains in an area around the transverse distribution device or in the container of the transverse distribution device after it has been moved outwards by the first conveying device.
  • the first conveying device and the second conveying device have a second offset in a second direction parallel to the feed direction.
  • the second direction is, in particular, perpendicular to the first direction. It is possible for the first and second conveying units to be offset from each other both in the feed direction and in the first direction. In such a case, the first and second feed directions are offset from each other.
  • this allows for particularly good homogenization of the spreading material by the transverse distribution device.
  • the first conveying device is configured to move the spreading material by means of rotation about a first axis of rotation.
  • the second conveying device is configured to move the spreading material by means of rotation about a second axis of rotation.
  • the first and second axes of rotation each pass through the respective conveying device.
  • first and second conveyor units are connected to a drive via a connecting element.
  • This connecting element could be a belt, such as a toothed belt.
  • the connecting element could be a shaft, such as a drive shaft.
  • the drive is, for example, a motor, in particular an electric motor.
  • the motor is a hydraulic motor.
  • the connecting element transmits the rotational movement of the motor to the first and second conveying units. It is possible for the first and second conveying units to be connected by a common drive.

  • the spreading material is moved from the storage area to the transverse distribution device by means of the feed unit.
  • the transverse distribution device is arranged in an intermediate container between the storage container and the spreading unit.

  • the transverse distribution device is arranged within the hopper. In the line of sight through the outlet opening, the transverse distribution device is preferably arranged above the outlet opening. In particular, the transverse distribution device is arranged above the spreading unit in the discharge direction. Preferably, the transverse distribution device is integrated into the hopper. That is, the mixing of the spreading material takes place within the hopper. In particular, this mixing takes place in a homogenization zone where the transverse distribution device is located. Preferably, the mixing zone borders directly on the outlet opening and thus on the spreading unit. This advantageously allows the spreading material to be homogenized in the storage container and evenly introduced into the spreading unit, which then distributes it evenly across the surface. This also advantageously eliminates the need for an intermediate container between the spreading unit and the storage container.
  • an intermediate hopper for the lateral distribution device is disadvantageous.
  • the intermediate hopper results in a comparatively low height between the spreading unit and the ground. This low height reduces the off-road capability of the vehicle or spreader. On uneven terrain, such a low height increases the risk of the spreader bottoming out. In such a case, controlled dispensing of the spreading material onto the ground becomes difficult or even impossible. Furthermore, the spreader can be damaged.
