Definitions

  • a spreading machine is specified.
  • the spreading machine is specifically designed to distribute a spreading material.
  • One of the tasks to be solved is to specify an improved spreading machine.
  • the machine comprises a hopper for spreading material.
  • the hopper includes at least one outlet opening.
  • the spreading machine further comprises a transverse distribution device and a feed mechanism.
  • the feed mechanism is configured to move the spreading material in the hopper in a forward direction towards the outlet opening.
  • the transverse distribution device is configured to distribute the spreading material transversely to the forward direction.
  • the transverse distribution device and the feed mechanism are each arranged within the hopper.
  • the transverse distribution device is integrated into the feed unit. It is possible that the hopper has a partition wall that separates the transverse distribution device from a storage area for the spreading material.
  • the transverse distribution device allows for a material flow across, preferably perpendicular to, the feed direction during operation of the spreading machine. This ensures thorough mixing of the spreading material and maintains a relatively homogeneous consistency. This is particularly advantageous because spreading material can clump depending on environmental parameters such as humidity or pressure, resulting in inhomogeneous density within the hopper. Such inhomogeneities typically hinder uniform dispensing of the spreading material through the outlet opening.
  • the spreading material can be dispensed from the hopper through the outlet opening. During operation of the spreader, the spreading material is applied to a surface.
  • the homogenization of the spreading material in the hopper, achieved through lateral distribution, allows for controlled application to the surface, minimizing material loss.
  • the feed device comprises, for example, a conveyor chain or a screw conveyor for moving the spreading material.
  • the spreading material is moved from the storage area to the transverse distribution device.
  • the feed device preferably includes a control unit for operating the feed device.
  • the control unit allows, for example, the speed of the conveyor chain to be set. Consequently, the control unit can be used to control the material flow in the storage container as well as the material flow through the outlet opening.
  • the control unit is, for example, also intended for controlling the cross-distribution device. Alternatively, it It is possible that the funding facilities are operated with their own independent control unit.
  • the hopper is mounted on a vehicle such as a truck.
  • the spreader is, for example, a mobile spreader.
  • the spreading material is preferably dispensed onto the ground from the rear end of the vehicle or spreader, viewed in the direction of travel. In normal operation, the spreading material is preferably applied while the vehicle is driving, and a layer of the spreading material with a predetermined thickness is deposited on the ground.
  • Transverse distribution devices are typically used in spreading machines to mix and homogenize the 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. To ensure the most uniform material flow possible through all these openings, it is therefore necessary to distribute the spreading material as evenly as possible.
  • the transverse distribution device typically includes a container in which the spreading material is moved and homogenized.
  • a disadvantage of this method is that an additional container is required between the storage container and the A suitable substrate must be provided to accommodate the transverse distribution device.
  • an additional hopper for the lateral distribution device has further disadvantages.
  • the additional hopper reduces the height between the openings through which the spreading material is applied to the ground and the ground itself. 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 distribution of the spreading material onto the ground becomes difficult. Furthermore, the spreader itself can be damaged.
  • the spreader described here utilizes the concept of integrating the lateral distribution device into the hopper. This integration allows for homogenization of the spreading material directly within the hopper. Advantageously, this eliminates the need for a separate container for the lateral distribution device.
  • the spreader described here overcomes the disadvantages mentioned above. In particular, it achieves a high degree of homogeneity in the spread material and simultaneously increases the spreader's off-road capability. The risk of damage to the spreader due to uneven terrain is reduced.
