Definitions

  • the invention relates to a spreader for or on a scattering vehicle and equipped with the spreader Winterdienst-Streuhus, the spreader comprises a grit container and a spreader having a rotating about a substantially vertical axis scattering plate for fan-like spreading of grit from the grit container ,
  • Winter service spreaders of this type are usually set up so that they are able to disperse both so-called blunting grit - namely sand or split - as well as detergents - especially salts - in a dry or moistened state.
  • road salt is often moistened before or during the scattering process with a dosed added liquid, the so-called brine, so it adheres better on the traffic areas and both during and after the scattering by the natural wind or the wind of the scattering vehicle or other vehicles much less Danger is exposed to being blown away.
  • the quality of spreaders was evaluated and optimized as part of a standstill trial.
  • the scatter pattern is observed behind a stationary vehicle.
  • Such attempts disregard the influence of the wind, which still causes very large turbulence and drift effects at high speeds, even when the material is moist. Therefore, the spread pattern is now being investigated behind a moving littering vehicle, with top speeds of more than 60 km / h being considered for use on motorways.
  • the DE 33 25 940 C1 was already proposed in 1983 to dispose of the Verwirbelungs- and Verwehungs compacte at fast-moving gritting vehicles above the spreader mecanicwindleit lake that detect the lateral and / or upper wind and so directed down to the scattering disc generated by the spreading disc, that the scattering plate fan-shaped leaving grit is pressed during its flight by the directed from top to bottom air flow directly on the traffic area to be sprinkled.
  • the requirementwindleit resonance may be formed as a flat or curved, from top front to back bottom inclined wall, as a hood-like wind tunnel or a shell-shaped hood with down-constricting shape.
  • the downwardly directed air flow also influences the trajectory of the scattering material and thereby the scattering pattern that forms on the road surface, whereby this influence changes both with increasing travel speed due to the increased air speed as well as with different types of scattering.
  • An automatic control of theêtwindleit vom-positioning for adjusting the acting from the top of the grit fan wind to different speeds and to be discharged Streustoffart is very complex.
  • the object of the present invention is therefore to propose measures to eliminate as far as possible the turbulence and drifting effects that are disadvantageous to the homogeneity of the scattering pattern and which occur due to the relative wind in the wake of a scattering vehicle.
  • a first measure for reducing the Verwirbelungs- and Verwehungs fare is to provide predominantlywindleit lake on the rear in the direction of travel of the grit container, the originallywindleit vomit vomit vomit vomit vomitas on the right and left of the grit container each comprise at least one lateral guide element, which are arranged such that they detect lateral wind, the one from their downstream ends to the rear, d. H. against the direction of travel, can flow.
  • the lateral airstream is thus not directed down to the spreading compartments, but the lateral guide elements have primarily the function of breaking the lateral airstream into partial streams.
  • the lateral guide elements deflect the lateral airflow toward the spreader or vehicle center.
  • they can be wing-shaped. By deflecting the lateral airstream towards the center into the wake of the scattering vehicle, the width of the dead water area in the air flow behind the vehicle and, as a result, the size and energy of the vortex bales can be significantly reduced.
  • the spreader is equipped with a device by means of which an essentially parallel to the spreading plate rotation plane air flow can be generated.
  • This air flow is preferably directly over, but may additionally or alternatively also be produced under the spreading plate. It protects the grit compartments in particular from above-acting, but also from laterally acting air currents.
  • an air flow generated under the spreading plate parallel to the spreading plate rotation plane it should be taken into account that this can also have an effect on the spreading pattern, since the spreading material is carried further with the generated air flow before it hits the road surface.
  • an essentially horizontal guide element for example a guide plate, is arranged above the spreading plate to produce the air flow substantially parallel to the spreading plate rotation plane.
  • a horizontal guide element may also be provided below the spreading plate, wherein a guide element arranged below the spreading plate can only have comparatively small dimensions, in order to avoid a collision with the scattering groove fan being thrown off the spreading plate.
  • the upper guide element can be designed over a large area and extend far back over the spreading plate.
  • the horizontal guide element may be formed as a semicircle or half ellipse with a diameter corresponding to the vehicle width or the grit container width and extend horizontally from the vehicle end to the rear.
  • the horizontal guide element prevents directed from the top or from below on the spreading plate air streams detect the grit fan. Instead, such air streams are discharged substantially horizontally across the baffle. This results in an air flow substantially parallel to the spreading plate rotation plane above or below the spreading plate.
  • dissipation elements are preferably provided, which decomposes the substantially parallel air flow into partial streams.
  • flow structures acting in a direction transverse to the main flow direction are interrupted.
  • the wake flow can be decomposed into a plurality of small swirl pots, which decay comparatively quickly and thus less influence the scattering pattern.
  • these dissipation elements are oriented approximately radially, so that the flow field is fanned out and the grit compartments are surrounded by a flow fan.
  • At least one upper guide element in addition as beforewindleit Structure, as it is known from DE 33 25 940 C1 is basically known and which serves to guide the wind, in particular from above the vehicle or grit container down to the horizontal guide element.
  • the so redirected upper air flow then hits approximately perpendicular to the horizontal guide element, preferably with a small component counter to the direction of travel, so that it is automatically redirected in a horizontal and thus parallel to the spreading plate rotation plane.
  • the more perpendicular the redirected upper airstream flow the stronger the stagnation point effect on the horizontal guide element and the more uniformly this flow is diverted by the horizontal guide element in the radial direction, so that automatically sets a fan-like flow field.
  • the upper guide element can be combined with the lateral guide elements described above, wherein it may be advantageous to form the lateral guide elements at least at the level of the horizontal guide element not as guide vanes, but just to the fan-like flow field of not to adversely affect the parallel air flow generated by the horizontal guide element.
  • At least a portion of the upper airstream may also be directed to below the spreading plate to produce there a substantially parallel to the spreading plate rotation plane air flow.
  • the upper guide element may be formed, for example, tubular, so that the upper air flow is passed through the upper guide element, or shell-like, as for example from the DE 3325940 C1 is known.
  • the effect of the upper guide element can be enhanced.
  • a brine supply line for supplying brine may be provided in the upper airstream guided by the upper guide element. Similar to the devices for deicing aircraft wings before take-off, the sprayed brine, with a corresponding droplet size distribution, impinges on the horizontal guide element from above and migrates on the guide element as liquid film predominantly to the trailing edge of the guide element. As a result, icing of the horizontal guide element is prevented.
  • To reinforce the parallel air flow relative to the horizontal guide element may be provided instead of the upper guide element and any means for actively generating an air flow, for example by means of a blower, a turbine or the like.
  • this nozzle can suck in and accelerate wind from underneath the vehicle and blow air flow over and / or under the grit fan compartments protecting the grit fan compartments.
  • a flow device according to the geometry of a Laval nozzle whose opening is located with a large cross section in the direction of travel to detect ground-level wind, and whose smaller outlet opening is opposite to the direction of travel, wherein the cross section of the nozzle from the inlet to the outlet opening passes through a minimum.
  • the above-described invention can be developed advantageously by at least one vertical guide element is provided as a further switchingwindleit phenomenon, which is arranged approximately centrally to the grit container and aligned in the direction of travel.
  • the vertical guide element can be arranged, for example, on the surface of the horizontal guide element facing away from the spreading plate.
  • the vertical guide element in the direction of travel can extend far beyond the scattering plate and beyond the horizontal guide element.
  • the for this purpose the disorderwindleitinci may be formed as a hollow body, so that they are heated from the inside.
  • the hollow body can be flowed through with a warm medium, wherein as the warm medium preferably the exhaust gases of the winter maintenance vehicle are used.
  • the hollow body can be directly or indirectly connected to the exhaust system of a winter maintenance vehicle.
  • Another way to avoid ice deposition is to pressurize the cavities at intervals with air pressure from the brake system. As a result, the surface expands so that ice deposits flake off.
  • the guide elements made of a flexible material, for. As plastic, formed.
  • Fig. 1 shows a scattering vehicle 1 according to a first embodiment in plan view.

  • lateral guide elements 6 are attached.
  • the lateral guide elements 6 are formed as a guide vanes to direct lateral airflow 7 of the flanks 8 of the scattering vehicle 1 in the caster 9.
  • the lateral guide elements 6 can be made jointly or individually adjustable to vary the skimming height and thus to make an adjustment to the crosswind situation.
  • the guide vanes 6 are designed as hollow bodies and are connected to an exhaust device of the winter maintenance vehicle (not shown) to flow through the guide vanes 6 to avoid icing with a warm medium.
  • the hollow body can also be acted upon with compressed air, the z. B. is diverted briefly from the brake system.
  • the compressed air supply leads to an expansion of the hollow body profile and thus to a chipping of icing.
  • a largely horizontal guide element 11 is installed in the illustrated variant of this embodiment above a spreading plate 10 in the form of a baffle.
  • the flow field 12 above the horizontal baffle 11 is decoupled from a scattered from the scattering plate 10 grit fan below the horizontal baffle 11 in a respect to the baffle dimension - but not with respect to the Leitblech Sign- short section.
  • the flow field 12 flowing away from the trailing edge 14 of the horizontal guide plate 11 is substantially parallel to the plane of rotation of the spreading plate 10 and, accordingly, substantially parallel to the scattering groove trailed by the spreading plate 10.
  • a vertical guide element 16 is further installed above the horizontal baffle 11, which is designed as a flat baffle and extends from the rear end of the grit container 3 to beyond the rear end of the horizontal baffle 11 addition ,
  • the vertical baffle 16 is located centrally to the vehicle 1 and extends parallel to the vehicle longitudinal direction.
  • the exact location and design of the vertical baffle 16 also depends on the location and design of the other spreader components, in particular the position of the hopper 10 leading downpipe 17 from. Location and shape of spreading plate 10 and downpipe 17 are in Fig. 1 therefore only shown schematically.
  • Fig. 2 shows a second embodiment, which also includes the horizontal guide plate 11 with the attached wedge-shaped dissipation elements 15 for dividing the flow field in partial flows 13.
  • a pivotable about a pivot axis 18 upper guide element 19 is provided above the grit container 3, which is similar to the above-described guide vanes 6 designed as a guide wing to guide upper airstream 20 down to the horizontal baffle 11.
  • a brine supply line ends in a brine nozzle 24, by means of which brine is injected into the upper airstream 20 covered by the upper guide vane 19 in order to protect the horizontal baffle 11 from icing.
  • the upper guide wing 19 is again hollow, so as to be able to flow through it in a manner not shown by means of a warm medium and to protect against icing, in particular when flowing with exhaust gases of the scattering vehicle. 1
  • the pivot axis 18 serves primarily to be able to pivot the upper guide vanes 19 from the grit container 3 to the rear in order to refill the grit container 3, for example, or to be able to remove it from the loading area 2.
  • this pivotal arrangement also allows a relatively simple variation of the flow direction above the baffle 11, which may be advantageous for adaptation to the spreading condition.
  • the connecting struts between the pivot axis 18 and the guide vanes 19 may be designed as lateral guide vanes.

  • Fig. 3 shows a variant of the upper guide element, which is not designed as a guide wing 19 but as a guide tube 21 here. Incidentally, this differs in Fig. 3 perspective scattering vehicle not shown in the Fig. 2 shown scattering vehicle, even if in Fig. 3 was dispensed with the representation of the other components of the spreader.
