Definitions

  • the present invention relates to a snow plow with at least two plowshares arranged next to one another, a gap having a narrow width being present between two adjacent plowshares.
  • Such snow plows are known as so-called multi-share plows.
  • multi-share plows With them, several ploughshare shares are suspended from a common frame, for example by means of two handlebars.
  • the individual plowshares can be moved independently of each other relative to the common frame. This enables only the ploughshare in question to dodge when it encounters an obstacle, while the other ploughshare remain in their clearing position lying on the road surface.
  • the plowshares are arranged next to each other, forming a gap between them.
  • snow or slush thrown up obstructs the driver's view of the clearing vehicle, particularly when the snow or slush is thrown onto the windshield of the clearing vehicle.
  • blown snow or slush can clog the lighting system and / or the engine cooler.
  • the present invention has for its object to provide a generic snow plow when used among all
  • REPLACEMENT LEAF Operating conditions obstruct the driver of the clearing vehicle and clogging of the front part of the clearing vehicle by snow or slush hurled.
  • this object is achieved in that, at least in the area of the at least one gap in the direction of travel, a covering element is provided behind the plowshares, which at least in some areas maintains a distance from the rear of the plowshares.
  • Snow or slush that penetrates through the gap between two plowshares hits the cover element and is collected by it.
  • the at least regionally provided distance of the covering element to the rear of the ploughshare means that the snow or slush does not accumulate in the gap, as a result of which the possibility of the ploughshare evading could be hindered. Rather, due to the distance between the back of the plowshares and the covering element, snow or slush falling on the covering element can fall down.
  • the distance of the cover element to the rear of the ploughshare is expediently chosen so that the self-cleaning of the cover element is guaranteed in all operating conditions; in practice this means that the distance is chosen so large that snow or slush adhering to the cover element falls down due to its own weight before the space between the cover element and the back of the plowshares is completely filled with snow or slush.
  • the self-cleaning of the cover element can be further increased by the fact that it consists of highly elastic rubber or rubber material. In this case, the cover element performs its own movements during clearing, through which the adhering snow is shaken off and can fall behind the plowshares.
  • a separate strip-shaped cover element is expediently provided for each gap between two plowshares. This feature also contributes to improving the self-cleaning effect, because in this way the fluttering of the covering elements that throws off the adhering snow is promoted.
  • conventional snow plows can also be retrofitted with such strip-shaped cover elements, because these can be arranged on the frame between the suspensions of the plowshares.
  • the at least one cover element is particularly preferably fastened to the snow plow in such a way that it is attached to at least one ploughshare or an elastic share extension attached to it and to the bottom of the snow plow frame.
  • the stretching of the strip-shaped cover elements that occurs when the plowshares evade favors their self-cleaning.
  • such a fastening presupposes the production of the covering element from a highly elastic material, so that the ploughshare's evasive movement with respect the frame is not hindered.
  • the cover elements are made from a non-elastic or only slightly elastic material, they are expediently attached to the frame of the snow plow alone.
  • Fig. 1 is a side view of an embodiment of a snow plow according to the invention.
  • Fig. 2 is a view of that shown in Fig. 1
  • the basic structure of the snow plow shown in the drawing is conventional. It therefore need not be described in detail.
  • the snow plow is suspended from the front of the snow-clearing vehicle by means of a carrying device known as such (see, for example, DE-AS 17.08 664).
  • the snow plow comprises a horizontally extending frame 1, which is constructed from a bending and torsion-resistant square tube.
  • Three plowshares 2a, 2b and 2c are suspended from the frame by means of the links 3 and 4, two upper links 3 and two lower links 4 being provided per ploughshare.
  • Each ploughshare is pressed down against the carriageway 8 by means of a helical spring 5 which is tensioned between an abutment 6 fastened on the rear side of the corresponding ploughshare and an abutment 7 fastened to the frame 1.
  • a gap 9 which enables an unimpeded relative movement of the plowshares with respect to one another.
  • the wind deflector 10 which extends the plowshares upwards, is slit in the extension of the column 9.
  • the corresponding slot 11 is T-shaped with a vertical section 12 that extends the gap 9 and a horizontal section 13.
  • the pivot bearing 14 can also be seen on the frame, on which the frame 1 is suspended on the support device (not shown) so that it can pivot about the vertical axis 15.
  • a strip-shaped cover element 16 is provided behind each gap 9 in the direction of travel (in order to be able to represent the arrangement and configuration of the slots 11 in the wind deflector 10, the right cover element was omitted in FIG. 2).
  • Each cover element 16 made of highly elastic rubber is bordered along its upper edge with a fastening fitting 17. This in turn is attached to the wind deflector 10 by means of a plurality of screws.
  • the lower end of each strip-shaped cover element 16 is also bordered with a fastening fitting. This is fastened with screws to the square profile of the frame 1 in the area of its lower front edge.
  • Cover strips of the format shown are completely sufficient to the pollution of Windshield, radiator, lighting device and the like to reliably prevent the snow removal vehicle from snow or slush penetrating between the plowshares.
