Definitions

  • the invention relates to a spreading vehicle with attached winter service spreading device for solid and / or liquid spreading materials, which has at least one spreading material container and a spreading device arranged behind the spreading material container in the direction of travel with a spreading plate rotating about an essentially vertical axis, from which the spreading material is spread out in a fan-like manner .
  • Winter service spreading devices of a more recent design are generally set up in such a way that they are capable of spreading so-called truncated spreading material, namely sand or grit, as well as thawing materials, in particular salts, in a dry or moistened state.
  • De-icing salt is often moistened with a metered liquid before or during the spreading process so that it adheres better to the traffic areas and is much less exposed to the danger both during and after spreading due to the natural wind or the wind of the spreading vehicle or other vehicles. to be blown away (DE-C-26 32 794).
  • the invention has for its object to provide winter service spreading vehicles of the type mentioned with a device by which the suction and the turbulence causing the swirling and drifting effects and the air turbulence are eliminated or rendered harmless and thus a more targeted, economical and environmental damage reducing Spreading the spreading material is made possible.
  • This object is achieved according to the invention in that above the spreading device a contour of the spreading vehicle and / or the grit container laterally and / or upwardly projecting wind flow guide surface is arranged, which directs the detected wind down to the spreading material fan generated by the spreading disc.
  • This device not only has the advantage that it can be implemented simply and at relatively low cost, or can also be retrofitted to spreading vehicles or winter service spreading devices which are already in use, but it has the advantageous property that its intended effect is automatic adapts to the given driving speed of the winter service spreading vehicle and that even at low driving speeds the spreading material leaving the spreading plate in a fan shape during its flight is pressed directly onto the traffic area to be sprinkled by the air flow directed downwards and that harmful air vortices are almost completely suppressed will.
  • This downward-directed air flow generated by the airstream baffle also has the additional advantage that the crust formation on the spreader parts and vehicle parts that has occurred in the previous salt, but especially damp salt scattering is almost completely, but at least largely prevented.
  • the device according to the invention additionally contributes to improving operational safety, because such incrustations of sprinkles on vehicle parts or on spreader parts often lead to malfunctions or material damage.
  • theußwindleit Structure from a flat or curved wall, z. B. consist of a sheet of metal or a plastic sheet.
  • the airflow guiding surface is part of a hood-like wind tunnel which on both sides runs at least approximately parallel to the longitudinal axis of the vehicle and / or the grit container and connects these wall elements , the upper outline of the grit container spans the roof wall at a vertical distance.
  • the entirety of the constitutional unit has a shell-like curved, narrowing shape with an approximately semicircular or semi-elliptical lower boundary edge.
  • Such a shaping can generate an increased or more concentrated downward air pressure, which affects the spreading material.
  • the headwind surface is directly at the rear end of the grit container by means of spacers. is attached.
  • the spacers are articulated to the airflow guide surface and / or the grit container and the inclination of the airflow guide surface is adjustable.
  • the spacers articulated to the airflow control surface and / or to the grit container not only can the inclination of the airflow control surface that is most favorable with respect to a predetermined driving speed or with respect to the grit to be deployed be set, but it is also possible to adjust the height of the airflow control surface in relation to to bring the spreading disc position into its most favorable position.
  • the airflow guide surface can be brought from its position of use into an at least approximately wind-neutral position and can be fixed in it. This configuration should make it possible to bring the airflow control surface for upland journeys to the place of use or from the place of use to the home location in a position in which it generates the lowest possible air resistance without having to be completely dismantled.
  • a truck 1 is shown in side view, on the loading platform 2, a winter service spreader 3 is placed.
  • the winter service spreader 3 has a grit container 4, which consists of a sheet metal body with sloping walls 5 leading to a conveyor trough 5 and an upper rectangular frame 7 and has three horizontal transverse foot rails 8 and side supports 9.
  • a longitudinal screw conveyor not visible in the drawing, which is driven by a hydraulic motor 10 in proportion to the driving speed and conveys the spreading material through a horizontal conveying pipe 11 into a down pipe 12 of a spreading device 13, through which it passes over a chute 14 onto one vertical axis 15 rotating spreader plate 16, which spreads it like a fan on the traffic surface 17 to be sprinkled.
  • the spreader 13 as seen in the direction of arrow 18, is located behind the grit container 5 outside the loading platform 2 and that the spreader plate 16 is arranged at a relatively small vertical distance above the traffic area 17 to be sprinkled .
  • a flat, downwardly directed airflow guide surface 20/1 with a flat roof wall 21/1 and side wall elements 24/1 and 25/1 forms a windscreen hood which only projects beyond the outlines of the grit container 5, that is to say wider is as the grit container 5 and therefore only detects the side wind and directs down to the grit fan. It is expedient if additional baffles are arranged inside the windscreen hood, which partially deflect the lateral airstream towards the center in order to achieve the most uniform possible air flow over the spreading material fan over the entire width.
  • the roof wall 21/1 is provided with a rectangular, the rear circumferential line of the grit container 5 adapted recess 21/2 so that a certain overlap between the side wall elements 25/1 and 25/1 on the one hand and the rectangular frame 7 of the grit container 4 on the other hand can be brought about and the entire windscreen hood can be attached to the rectangular frame 7 by means of lateral bolts 30 and 31.
  • angled support rails 32 and 33 are provided for fastening the windscreen hood.
  • This embodiment of FIG. 3 has the advantage that the upper outlines of the grit container 4 are not surmounted by the headwind surface 20/1 and that the headwind surface in no way hinders the opening and closing of the grate cover.
  • the airflow guide surface 20/2 is formed by an obliquely curved sheet metal plate 22/1, which is provided with lateral bevels 24/2 and 25/2 and by means of spacers 26/1 and with support brackets 27/1 is adjustably attached to the rectangular frame 7 of the grit container 4.
  • the sheet 22/1 has a greater width than the grit container 4, and its arrangement is such that it also extends above the upper contour lines of the grit container 4 in order to direct the detected wind during the spreading operation onto the grit fan 16 generated by the gritter plate 16 .
  • the airflow guide surface 20/3 arranged above the scattering device 13 forms a hood-like wind tunnel 22 together with two lateral vertical wall elements 24/3 and 25/3 and with a roof wall 21/3 / 3, which protrudes the outlines of the grit container 4 both above and on both sides.
  • this windscreen hood 22/3 which forms the airflow guide surface 20/3 and is directed obliquely downward, is arched from a straight upper boundary edge 22/4, which at the same time represents the connecting edge with the roof wall 21/3.
  • the front boundary edge 21/4 of the roof wall 21/3 also has an upwardly protruding curvature.
  • This windscreen hood 22/3 is fastened by means of spacers 26/3 and 27/3 which are arranged in pairs and are articulated and which are articulated on the side wall elements 24/3 and 25/3 or on the side supports 9.
  • this windscreen hood 22/3 can also be adjusted with respect to the direction of its airflow guide surface 22/3 or, as indicated in FIG. 1, can be brought into a position in which it opposes the airflow as little as possible.
  • the headwind surface 20/4 has a shell-like hollow shape with an approximately semi-elliptical lower boundary edge 33, which limits a much narrower cross section than its upper boundary edges 34, 35 and 36, which are connected to side wall elements 24/4 and 25/4 or to gable roof-like roof wall sections 38 and 39 which run approximately parallel to the cover surfaces of the grit container 4.
  • the air draft hood 40 thus formed projects beyond the outlines of the grit container 4 both upwards and laterally.
  • a support bracket 41 is articulated on the conveyor tube 11 by means of a hinge bracket 11 ', which can be adjustably connected to a support tongue 43 by means of a plug-in mandrel 42.
  • the support tongue 53 is fastened in the center near the lower boundary edge 33 to the wall of the air draft hood 40 forming the airflow guide surface 20/4 and is provided with a plug-in hole for receiving the plug-in mandrel 42, while the support tab 41 has a plurality of plug-in holes 44 at its upper end .
