Definitions

  • the invention relates to a contrivance for the removal of snow, gravel, soil, and the like - that is, a snowplough viz. an appliance fitted to the front end of a tractor and designed to clear roads, streets and open spaces when driven forward by the tractor, capable of shifting gravel, soi I and other such loose material in general °
  • the prior art is able to show snowploughs of a type having a pair of blades arranged in an adjustable wedge-formation which will open out into complete alignment one with the other, though without offering an unbroken suface at the join, and with a buffer element isolated from the blades themselves; the prior art further comprises single blade ploughs, which are in fact alone in providing for forward inclination of the blade top-edge in order to allow for scraping and sideways dispersal of accumulated ice and snow; the forward angling of this upper edge -and indeed its backward inclination, to avoid unwanted removal of gravel down the central path of the blade- being obtained by way of a horizontal pivot allowing rotation of the blade with respect to the same pivot's centre support, the turning motion imparted direct by the rod of an oil-hydraulic actuator cylinder.
  • the invention resolves the problem thus stated by providing for the blade top-edge inclination utilising an arrangement of two vertical pivots and single horizontal pivot; a first vertical pivot passing though the central buffer element held in position by two pairs of overlapping rear blade-lugs, the upper pair of said lugs embraced by a horizontally-disposed yoke paired to this same first vertical pivot aid provided rearwardly and at either side with horizontal pivots converging toward the rear which provide anchor points for hinging the rod extremities of a pair of actuator cylinders hinged at their rearmost part to the main plough-to-vehicle chassis and converging to the fore.
  • a second vertical pivot is disposed at the forward extremity of a double vertical articulating parallelogram converging thereon and carrying a pair of horizontal pivots disposed within a relative pair of horizontal bushings affixed at a tangent to respective vertical bushings forming part of a turning pair by mans of which the cylindrical pivoting extremities of a vertical prismatic pivot are supported in rotation; the said prismatic pivot is accommodated -with a degree of play- within a vertical bushing having prismatic inner surface and offering countersunk upper and lower extremities, the forward wall of this same vertical bushing affording support to a horizontal bushing paired with the aforementioned horizontal. pivot about which the blade assembly is caused to rotate.
  • this shows a forward surface area curving away in two directions in such a way as to maintain unbroken contact with the two blade-end inner surfaces.
  • Speedier fitting-up to the prime mover is obtained by two double-articulated couplings which make use of a safety mechanism preventing their becoming unhitched a Advantages offered by the invention are these: the use of a single adjustable wedge-formation snowplough capable of inclining forward or to the rear regardless of the blade aspect, instead of two separate ploughs -one fixed-angle wedge and the oter, an inclining single blade: this signifies a marked saving in capital outlay, time, garaging space and maintenance; the possibility of obtaining side-on angle of more than 45°; speedy and exact hitching even though the plough may be out of horizontal and not perfectly lined up with the tractor linkage -for instance separated by ten centimetres or so; perfect union between the central element and the blades regardless of the latter's position whether angled or aligned at 180°; greater lift from ground level for
  • 1 and 2 denote the pair of plough blades
  • 3 denotes the central buffer element set at the join of the actual blades
  • 4 and 5 denote a pair of upper central horizontal lugs protruding from the blades, offset in terms of height and paired with a vertical pivot 6, this in turn pairing in its upper region with a horizatal plate 7 which forms the upper rearwardly-disposed component of central buffer element 3
  • 8 denotes a horizontal yoke, disposed to the fore and hinging with the uppermost portion of pivot 6, operation of said yoke 8 bringing about the inclination forward or to therear of blades 1 and 2 with respect to the vertical
  • the lower branch of yoke 8 makes slip- contact with the topside of plate 7, whilst the upper branch of same is offered to a nut 9 securing the uppermost extremity of pivot 6, the interspace between said branches serving to accommodate the rearmost overlapping portions of lugs 4 and 5
  • 10 denotes a pair of side-irons made fast to
  • A represents the angle formed between the centre axis C of blades 1 and 2 and the longitudinal axis L of the contrivance poper, produced by rotation of blades 1 and 2 through a horizontal plane with respect to pivot 19;
  • 46 denotes the lower plate appendage of central buffer element 3 which combines with upper plate 7 in supporting vertical pivot 6;
  • 47 denotes a plate forming un upper appendage of lower plate 46 and creating a pocket 48 therewith in which to accommodate that lower pair of lugs 49 and 50 protruding from blades 1 and 2 which correspond to upper lugs 4 and 5, each said lug 49 and 50 being paired with vertical pivot 6;
  • forward-facing flanks denoted by 49' and 50' relative to the side- and rear-extending portions 49" and 50" of each respective lug, perform the function of checking flanks offered thereto by buffer elemet 3 (see figs 4' and 4")a
  • 51 denotes a pair of lugsrelative to each of pivots 40 and 41 and engaging -height adjustably- with uprights 53 whose lower regions bear pivots 54 paired with the lugs of skids 56 aforementioned, these in turn connecting by way of struts 59 with the pivots 57 of further lugs 58 protruding from each of blades 1 and 2;
  • 60 and 61 (in figs 9 and 10) denote two pairs of vertical pins, lower and upper respectively, each provided with an undercut 62 and fitted in pairs to the fore-ends of side-irons 10;
  • 63 denotes two pairs of brackets, both capable of vertical oscillation and provided with a hole 64 at the rear extremity of the single bracket arm 63 by means of which to engage the undercut portion 62 of eah of pins 60 and 61, the hole diameter 64 being greater than that of the latter; the inner fore-end of each bracket arm 63 is furnished with a pair of vertical lugs 65
  • R denotes the straight line passing through the centre points R1 and R2 of pivot 66 and the undercut portion 62 bf either pin 60 and 61, respectively.
  • the centre point R3 of pivot 69 lies outside the pdh of straight line R and toward its relative bracket arm 63 thus ensuring a secure and stable fit
  • 73 denotes a vertical transverse plate attached to side-irons 10 and offering a centre aperture 74 through which -to the end of obtaining a properly-centred hitch- the extension 14 of sub-chassis 12 is directed.
  • central buffer element 3 offers a vertical concave face to the fore and a transverse concave profile to the rear in order to maintain unbroken contact with blades 1 and 2 in whatever position; moreover the centre body portion of the element is hollow, the cross-section thereof showing a rounded forward profile and a rectilinear profile to the rear, the lower region of which offering a pair of stop-flanks to blades 1 and 2 during closure of the latter; supporting lugs for horizontal pivot 22 issue forth from the vertical transverse rear buffer wall whilst resting upon aforesaid lower plate 47 protruding rearward from the said buffer element
