Definitions

  • the present invention relates to a spreader, in particular for winter service vehicles, comprising a spreader material container delimited by rigid walls with a ground-side spreader material discharge device extending in the longitudinal direction of the spreader device, a spreader material discharge device fed by this device, and a liquid system which has at least one shaped and variable-volume tank bag includes.
  • the ratio between the solid spreading material to be spread and the liquid used to wet it depends on a large number of factors. Under certain conditions it is even advantageous to use pure liquid (e.g. brine) to the traffic surface, typically using additional spray equipment.
  • pure liquid e.g. brine
  • the aim is to optimize the efficiency of anti-icing measures in the sense that road safety is guaranteed in the long term with the minimum use of expensive and/or environmentally harmful materials, with another important aspect of economic efficiency being the avoidance of as much as possible unproductive empty runs.
  • this means that the aim is to be able to vary the ratio of the amounts of solid spreading material on the one hand and liquid on the other hand carried by the winter service vehicle within a considerable range.
  • various proposals have been made in the past for spreaders of the type specified above, in which at least one shape and volume-changeable tank bag is arranged in the interior of the spreader container. Depending on the degree to which it is filled, a more or less large "residual space" is available for accommodating solid spreading material.
  • the relevant prior art includes in particular the EP 579311 A1 , the DE 19733359 A1 , which describes the subject-matter of the preamble of claim 1, and the WO 2014/135418 A1 .
  • the spreading device according to the invention which has the features set out in the introduction, is also characterized in particular by the fact that - in synergetic functional interaction with each other - the at least one tank bag is accommodated in a partial space of the spreading material container that can be changed in shape and volume, which is separated by a front and a rear transverse wall and an inherently rigid, laterally adjustable partition wall, at least in the sense of reducing the volume of the partial space by means of an adjustment drive, is actively positionally adjustable, with a trickle seal acting between the partition wall and the two transverse walls delimiting the relevant partial space at the front and rear, which acts in the manner of a along a first edge on the dividing wall and a second edge on the respective transverse wall fixed rolling diaphragm and also changes its geometry when the
  • the active adjustability, i.e. in particular active pivotability (see below) of that intrinsically rigid partition wall that laterally delimits the partial space accommodating the tank bag, by means of an adjustment drive, at least in the sense of reducing the volume of the partial space, is particularly important insofar as the respective The position of the partition can dictate the geometry of the partial space and thus the geometry of the tank bag accommodated in this.
  • the present invention permits this said active specification of the geometry of the partial space active specification of the geometry of the tank bag accommodated in this even if it is only partially filled. This is an invaluable advantage for optimal utilization of the total volume of the spreading material container with changing ratios of solid spreading material and liquid under different operating conditions.
  • the sealing of the partition wall against the two transverse walls delimiting the partial space at the front and rear which is also provided according to the present invention, via trickle seals designed in the manner of rolling membranes and the fact that the partition wall forms a rigid component - and does not consist of several partition wall segments that can be moved relative to one another, in particular that can be slid relative to one another.
  • the partition wall made of segments that can be moved relative to one another would be a particular hindrance in realizing permanent and reliably effective protection against the ingress of solid spreading material into the at least one partial space accommodating the at least one tank bag, specifically in the two edge regions of the partition wall near the both transverse walls. Due to its design in the manner of a rolling membrane, which is fixed along a first edge to the partition wall and a second edge to the respective transverse wall, the trickle seal also changes its geometry when the position of the partition wall changes relative to the transverse wall in question.
  • the rolling diaphragm is typically dimensioned in such a way that it can also move in the two extreme positions of the partition wall extends essentially without tension between the edge fixed to this edge and the edge fixed to the transverse wall in question, so that an elongation of the rolling diaphragm during operation is typically at least largely avoided.
  • the trickle seals designed in the manner of rolling membranes promote the smooth adjustability of the respective partition wall, which is of great advantage in particular for the implementation of the invention using comparatively simple adjustment drives (see below) that are only active in one adjustment direction.
  • the active adjustability of the partition wall by means of an adjusting drive which is described above and acts to a certain extent only in one direction, i.e. in the sense of reducing the subspace, is usually sufficient because the hydrostatic pressure that acts in the tank bag due to the liquid contained in it and from the partition is added, acts on the latter in the sense of an increase in the volume of the partial space.
  • the said partial space accommodating the tank bag can also be delimited by a side wall of the grit container.
  • the partition wall can be articulated so that it can swivel sideways, specifically in the region of its lower edge, so that the adjustment drive is designed as a swivel drive.
  • the application of the present invention effectively prevents solid spreading material from penetrating into the sub-chambers of the spreading material container that accommodate the tank bags, several sub-chambers arranged one behind the other and separated from one another by a partition can be provided on each side of the spreader without impairing the reliability and operational safety.
  • at least one of the transverse walls is preferably formed by an intermediate wall which is arranged between two tank bags arranged one behind the other in the longitudinal direction of the spreading device and delimits the two sub-spaces in question from one another. In this way, mechanical loads acting on the material of the tank bags can be substantially reduced in special operating situations (e.g.
  • the distribution of the total capacity of the tank bags over a larger number of them allows a particularly high degree of flexibility and usability of the spreader. Because, for example, in the event that only part of the total capacity of the tank bags is required to carry liquid for a specific application, it is more convenient for the practical use of the spreader to divide this amount of liquid into two maximum filled (e.g. front) tank bags and Distribute two (e.g. rear) tank bags that are only filled with the remaining amount.
  • the present invention also explicitly excludes embodiments with only two tank bags (arranged on different sides of the spreader) or even just a single one Tank bag included.
  • the partitions delimiting the partial spaces are particularly preferably not flat, again with regard to the optimal usability of the spreading device in terms of flexible use, but rather form a concave delimitation for the respective partial space.
  • the partition walls can each comprise two substantially planar partition wall sections which abut at one edge, are rigidly connected to one another or merge into one another. In view of the funnel effect of the partitions (pivoted to the side as far as possible), this is advantageous, for example, for filling the spreading material container with solid spreading material.
  • the rigid partitions are each pivoted laterally on an intermediate floor arranged within the spreading material container, with the respective partial space being closed off at the bottom by said intermediate floor and the associated tank bag correspondingly resting on the intermediate floor.
  • the intermediate floor is arranged considerably above the spreading material discharge device, so that an area for solid spreading material always remains below the intermediate floor.
  • a fluidic coupling of the at least one side tank and the at least one tank bag arranged higher than this results in a hierarchical removal of liquid from the at least one tank bag and the at least one side tank, that when liquid is used, it is first removed from the at least one tank bag and only then, when the at least one tank bag is completely or at least largely emptied, from the at least one side tank. Or vice versa: When filling the side tanks and tank bags communicating with one another (via a filling connection assigned to the at least one side tank), the at least one side tank first fills up completely (or at least largely completely) before the at least one tank bag fills up.
  • the intermediate floor is perforated to a greater or lesser extent, so that the partial space delimited by it communicates with the area of the grit container lying underneath via openings. In this way, any foreign bodies that have gotten into the partial space can leave it downwards and be discharged from the spreader together with the solid spreading material.
  • the pivoting drive for the partition includes straps, belts, ropes or comparable flexible traction means.
  • the tank bag--at least in its completely filled state and with the corresponding maximum volume of the respective partial space--can bear against the flexible traction means.
  • the flexible traction mechanism of the pivoting drive also performs a stabilizing function, which also counteracts impermissible deformation of the tank bag due to sloshing of the liquid contained, particularly when the winter service vehicle accelerates and brakes.
  • winches are provided for winding up the flexible traction means, these are particularly preferably arranged in the respective partial space adjacent to the side wall of the spreading material storage container.
  • linear adjustment drives e.g. rack and pinion drives, hydraulic cylinders.
  • the pivoting or other adjustment drive for the at least one partition wall is designed as a spring drive.
  • a swiveling drive comprising belts, belts, ropes or comparable flexible traction means is provided for the at least one partition wall.
  • a spring drive which can comprise a tension spring, for example, can act on the at least one flexible traction means, namely in the sense of reducing that subspace that is formed by the partition wall assigned to the flexible traction means in question is limited.
  • the respective partition wall can be locked in different positions by means of a latching or locking device, whereby after the latching or locking device has been released it is moved by means of the spring drive in the sense of reducing the associated subspace.
  • the spring can be designed as a tension spring extending in the longitudinal direction of the spreader, in which case the flexible tension means is deflected via a roller or other deflection device.
  • the respective partition wall adjustment drive is designed as a spring drive in the above sense, it is also favorable to provide at least one separate partition wall stop element, which defines the position of the partition wall that corresponds to the maximum possible volume of the subspace concerned.
  • partition wall stop elements can advantageously be flexible themselves, for example by being designed as belts or belts that extend above the tank bag in question between the respective partition wall and a stationary component (side wall, cover, or the like) of the grit container.
  • each tank bag is suspended at its opposite upper edge regions from the associated partition and from the side wall of the grit container. In this way, the tank bag is prevented from collapsing as it is increasingly emptied. Rather, the at least one tank bag remains at least essentially at the same level when it is only partially filled as when it is completely filled.
  • the partition-side suspension can in particular Area of the partition stiffening struts, which in turn preferably extend up to joints by means of which the partition is pivotally articulated.
  • the spreading material container has at least one rigid, stationary cover which is arranged above the ventilation sockets and which, given its minimal volume, closes off the partial space at the top.
