Definitions

  • the invention relates to a spreading device for spreading liquid and granular spreading material according to the preamble of patent claim 1.
  • Such spreading devices have a rotatable spreading disc with a distribution hub and a spreading disc shaft, by means of which the spreading disc can be rotated.
  • the spreading disc shaft is rotatably mounted in a central housing body.
  • the spreading device comprises a spreading material delivery device for delivering the liquid spreading material onto the distribution hub, wherein the spreading material delivery device has a spreading material outlet opening, which is directed towards the distribution hub.
  • the liquid grit is fed to the grit dispenser by means of a feed line.
  • Such spreading devices are usually used in the rear area of winter service vehicles, for example Trucks, attached to spread liquid and / or granular material on roads or other surfaces.
  • the spreading material should be applied to the ground as evenly as possible and in a predetermined spreading width by the rotating spreading disc.
  • a brine i.e. a saline solution
  • granular grit is, for example, road salt.
  • Moist salt is often used here, i.e. a road salt that is moistened with a salt solution (brine). Compared to dry road salt, such a damp salt has the particular advantage that the desired thawing effect occurs very quickly and there is a significantly lower risk of drifting.
  • the brine and the dry road salt are usually brought together in the area of the spreading disc distribution hub, which is preferably designed as a conical baffle, to which the brine is supplied on the one hand by means of a brine dispensing device and on the other hand the road salt is supplied via a chute.
  • the invention is therefore based on the object of providing a spreading device of the type mentioned at the outset with which the best possible mixing of liquid and granular spreading material and the most uniform and targeted distribution of the spreading material on the ground can be achieved.
  • the position of the spreading material outlet opening for the liquid spreading material can be changed in the circumferential direction of the distribution hub by means of an electrical, hydraulic or pneumatic actuator.
  • the location of the mixing between the liquid spreading material and the granular spreading material changes accordingly, as a result of which the mixing process can be optimized depending on the composition of the liquid and granular spreading material, the driving speed and the desired spreading width.
  • the mixing process can be improved at any time and in a very fine manner - if necessary by interacting with a motorized adjustment of the grit chute and / or a motorized pivoting of the spreading device or parts thereof about one or more vertical axes and be adapted to the respective requirements.
  • the spreading material delivery device for the liquid spreading material is advantageously rotatable around the shaft housing.
  • the spreading material outlet opening describes a circular arc around the longitudinal axis of the shaft housing and thus about the axis of rotation of the distribution hub during the position adjustment.
  • the grit delivery device advantageously consists of a grit delivery box which extends around the shaft housing and is rotatably mounted thereon.
  • the liquid spreading material can initially be collected somewhat in the immediate vicinity of the spreading plate and from there via the grit outlet opening can be directed to the distribution hub. In this way it can be achieved in a simple manner that the liquid spreading material is always available in the area of the spreading disc when required and from there can be optimally dispensed onto the distribution hub in every rotational position of the spreading material delivery device.
  • the actuator advantageously has a length-adjustable actuating arm which is coupled in motion to the grit delivery device in such a way that a change in length of the actuation arm causes the grit delivery device to rotate about the axis of rotation of the distribution hub.
  • the actuating arm of the actuator is motion-coupled to the feed line for the liquid spreading material, such that the feed line is part of a force transmission device for rotating the spreading material delivery device.
  • this means that the actuating arm of the actuator is not connected directly to the grit delivery device, for example grit delivery box, but to the feed line for the liquid grit and moves the grit delivery device by means of this feed line.
  • the feed line between the connection point with the actuating arm and the grit delivery device is rigid in such a way that the movement is transferred to the grit delivery device without any significant deformation of the feed line.
  • a very simple construction is possible by means of such an embodiment.
  • the grit delivery device is advantageously held axially on the shaft housing by means of the feed line for the liquid grit. This eliminates the need for additional axial bearings between the grit dispenser and the shaft housing.
  • the grit delivery device is held at the correct height on the shaft housing solely by the feed line, the feed line advantageously being guided relatively close to the grit delivery device by a suitable guide device.
  • the spreading device has a guide plate attached to the shaft body and a slide element which is displaceably guided on the guide plate in such a way that it can be moved by the actuator on an arc around the spreading disc shaft, the slide element being coupled in motion to the spreading material delivery device.
  • the guide plate has an arcuate elongated hole which forms a guide link into which at least one guide pin attached to the slide element engages.
  • the longitudinal movement of the actuating arm can be converted in a simple and safe manner into a circular movement of the slide element around the spreader plate shaft.
  • This circular movement can then be transmitted from the slide element - preferably via the feed line for the liquid spreading material - to the spreading material delivery device, so that it also rotates correspondingly relative to the distribution hub, whereby the position of the spreading material outlet opening can be varied relative to the distribution hub.
  • the actuator for changing the position of the grit outlet opening for the liquid grit preferably consists of an electrically operated drive motor. This enables a relatively simple construction, since no additional hydraulic or pneumatic line is required. A hydraulic or pneumatic drive is also possible.
  • the spreading device comprises a spreading plate module, which comprises the spreading plate, a spreading plate cover and the shaft housing, as well as a spreading slide and a holding structure attached to the spreading slide for pivoting mounting of the spreading plate module relative to the spreading slide, the spreading plate module by means of a second electrical, hydraulic or pneumatic actuator can be pivoted relative to the spreading chute such that the point of impact of the granular spreading material supplied via the spreading chute on the distribution hub can be changed.
  • a second electrical, hydraulic or pneumatic actuator can be pivoted relative to the spreading chute such that the point of impact of the granular spreading material supplied via the spreading chute on the distribution hub can be changed.
  • this second actuator it is possible to pivot the entire spreading disc module about a vertical axis in such a way that the granular spreading material from the spreading chute hits the distribution hub either in the middle or laterally further to the left or right.

  • the scattering chute has a lower discharge section, which is by means of a third electrical, hydraulic or pneumatic actuator can be pivoted about a horizontal axis in such a way that the point of impact of the granular material to be spread on the distribution hub can be changed in the vertical direction of the distribution hub.
  • This is another motorized adjustment option to change and optimize the spreading pattern and the positioning of the spreading material on the ground.
  • the spreading chute has an upper chute section and a lower chute section, to which the holding structure for the pivotable mounting of the spreader plate module is fastened, the lower chute section being rotatably mounted on the upper chute section and being rotatable by means of a fourth electrical, hydraulic or pneumatic actuator .
