Known sno wploughs are designed with « support frame lor » ploughshare Ä he coupled to a curbing vehicle, wherein if can be lifted pu the^one hand to a raised position by pivoting by means of a hydraulic system located on the carryingvehiclein:order to be able to transport the snowplough to a place of use., and can be lowered into the operatinf position et the place of use on the other hand, whereby the lower edge of the ploughshare can bo ibwered to rest on a ground surface., from which snow or Ice is to be:cieeredi f 0QD2;I· F u rthe rmore, the pin ughshste is pivotably mountei m the support frame about ah approximately vertical avis, and atieastpne adjusting device,, in particular at least one hydraulic cylinder, isiprovlded on thé support franse, by means of which the ploughshare can be adjusted In any desired angular position w the: support frame or In relation to the: direction of travel. jÖOOäj: irvthe operation of sfmwpioughsywhleh are moved over ground surfaces, them lathe difficulty that ohstaciesvsuch 31 edge atones,: paying stones, sewer covers and the like, can be located in the gröund surfâtes, on whlcbfhe ploughshareoniagcs, as a result of which the ploughshare canhe damaged fhi psrticular ijthesűí^iiSf^r or the obstacles can be damaged or removed, in order to avoid1 this^ it is known to make :the :pio;Uihdhate::heigbt-'adjystable In relation to the support fram:e, Vts a:resulti: tbe ploughshare cap be moved: upwards in relation to the support frame es; soon as; it travels onto eh obstacle, by means of Which the obstaole is driven over by the ploughshare,.

[0004] Another solution to this problem is to form the ploughshare with a share plate of a rubber-elastic material, in this case, the share plat® Is elastically deformed during its trawl onto a rigid obstacle, whereby If reaches over the obstacle. Such share plates consist of rubber plates with a thickness of 30 mm to 50 mm, which: are miefively stiff or rigid due to this thickness, jöödäf Ploughshares are futlbéfiknswmwbfcb-dô^p^iiriÂl^tt support frame> wherein the iudlvldpalipafty ofthe support frame are pivotably connected in an articulated manner to one another sbont approximately vertical axeSi and ars integral share plate-made of a rubber-elastic material Is- fixed fjgihfto the ihbhbduai pïM of the share earner. Sued ploughshares consist, for example, # a centrât part of The support frame and two lateral ends Pf the support Warna, which ara pivotably mounted on the middle part about appsoximateiy vertical axes, wherein the share plate consisting pf a ruhbeoelasfle mata rial Is rigidly fastened to alt parts of the support frame, A pleating of the two end pa rts of f he sha re plate is Iherefere advantapourt: since thus the operating mode: of the snowplough can: he adjusted to the sphtlat conditions or repu hepíents, :pue to the high sbffdessof theshare plate, hOwevehtbe two and parts of The support frame can only he piloted at vary small angles relative to the centrai: part of the support frame, föd« Tha present Invention Is therefore hasad on the object of improving a snowplough of the type described ahova In snobs way that this dlsadpovage is avoided. This; Is achieved according to the invention in such a way that parts of the shore plate or the entire share plate: ls/arefastened to the support frame for the share plate in an adjustable manner in relation thereto, [0007] Preferably, the support frame bar the share plate is formed with a mam part and at least one of its two lateral ends with an end part which can be pivoted towards the main part about an at; least approximately vertical axis, wherein the share plate is rigidly faSfeoed to the main part, whereas if is fastened to the at least one end part of the support frame for the share piste in: an: adjustable manner irt relation thereto.

In this case, the support frame for the share plate can he formed with a middle main part and with two end parts which can be pivoted in relation to the middle main part, wherein the share plate is adjustably fastened at the two end parts of the support frame for the share plate, especially displaceable in relation thereto, in this case, the main part of the support frame for the share plate can extend over approximately half the length of the entire support frame for the share plate, 18CK3S] Preferably, the support frame fer the ploughshare is formed with at least One adjusting: cylinder, by means: of which the support frame for the share plate can he pivoted about an approximately vertical axis relative to the support frame for the ploughshare, and the support frame for the share plate for pivoting the at least one end part of the support; frame for the share plate Is formed with at least one further ad|osing cylinder, fSÖÖSj; Accordlbg to a further embodiment according to the invention, the support frame fer the share plate is formed with two parts, which are pivotably connected; to each other In an articulated manner about an at least approximately vertical axis, wherein the share plate is adjustably fastened it the two end parts of the support frame for the Share plate, especially displaceable in relation thereto. In: this case, the support frame for the ploughshare Is preferably designed with two adjusting: cylinders, by means· of which the two parts of the support frame: for the share: plate can he: pivoted: Ih relation to the support frame for the ploughshare.
