Definitions

  • the present invention relates to machines for clearing snow, particularly to an apparatus for support and suspension of a snowplough blade.
  • the blade When the vehicle moves with the blade in non-use configuration, the blade is raised from the road surface, and the more advanced technical solutions limit the blade oscillation amplitude, when in non-use position.
  • the document EP 0 362 837 describes an apparatus for support and suspension of a snowplough blade.
  • This apparatus includes a plate, which can be fastened to the vehicle.
  • the ends of the frames form a collar.
  • An upright of the snowplough blade supporting structure is articulated to said collars along transversal axes, so as to allow the blade to oscillate with respect to a vertical plane.
  • the upright is equipped with an extension which, when the blade is raised, engages with a relative seat made in the blade frame, so as to limit the blade oscillation in vertical plane.
  • the DE-A-195 14 013 discloses an attachment linkage used to join a snowplough blade to the front of a pusher vehicle. It incorporates pivotable outliers which consist of swivel arms arranged vertically one above the other and mounted to swivel about the horizontal axes on the carrier plate. A lift cylinder is connected to the two swivel arms. Two side adjustment cylinders are connected at one end to the lower swivel axis and at the other end to the carrier frame for the snowplough.
  • the carrier plate has a vertical cheek on each side.
  • the object of the present invention is to propose an apparatus for support and suspension of a snowplough blade, which optimizes the blade dynamic positioning during the use thereof and which stabilizes the blade in raised position while the vehicle to which it is fastened moves in out-of-operation condition.
  • Another object of the present invention is to propose an apparatus, which stabilizes the blade by locking the means supporting the blade directly to the structure fastened to the vehicle.
  • a further object of the present invention is to propose an apparatus obtained by simple elements, which are easy to assemble and maintain.
  • the reference numeral 30 indicates a vehicle, in front of which a carrying structure 35 is fastened in known way.
  • the reference numeral 40 indicates schematically a snowplough blade; the proposed apparatus 100 is positioned between the snowplough blade 40 and the structure 35.
  • the apparatus 100 includes:
  • the first linking means 37A are not shown in detail and include a ball joint.
  • the second linking means 37B include (see Figure 2):
  • the third linking means 39A include a pair of coaxial hinge pins 65 with transversal axis, only one of which is seen in Figures 1A, 1B.
  • the fourth linking means 39B include:
  • the two half-shells do not form a full ring, so as to allow the lower arm 38 to oscillate with respect to the axis K in one direction or the other by a few grades, e.g. 4 - 5° in both directions with respect to the zero position.
  • the means 50 for locking and releasing the upper arm 36 to and from the structure 35 include:
  • the extension 82 is positioned in such a way as to enter the hole 81 of the second part 80B due to upwards rotation of the arm 36.
  • first hydraulic means 70 are fastened from one side to the structure 35 and from the other side to the upper arm 36 by linking means 70A, 70B, similar to the above mentioned first and second linking means 37A, 37B, i.e. formed by a ball joint.
  • the means 42 for adjusting the blade 40 inclination with respect to a vertical plane include two groups of holes 91A, 91B, made in the strengthening ribbing 40A of the blade and positioned in parts opposite with respect to the blade transversal oscillation axis.
  • the holes of each group of holes are arranged along a circumference arc, centered on the blade transversal oscillation axis.
  • the upright 41 features, made therein, two threaded holes, not shown, centered on the above mentioned circumference arc in parts opposite with respect to the above mentioned axis.
  • the hydraulic means 90 drive the upright 41 - blade 40 assembly into rotation with respect to the vertical axis W, so as to define the blade inclination with respect to the vehicle 30 movement direction, while the means 42 adjust the blade position with respect to a vertical plane.
  • the blade 40 assumes the configuration indicated with P in Figure 5.
  • the hydraulic means 70 drive the upper arm 36, together with the upright 41 - blade 40 assembly, into upwards rotation until the extension 82 couples with the hole 81 (non-use position I, Figure 1B).
  • the upper arm 36 cannot oscillate about its axis.
  • the upper arm is fastened to the structure 35, which makes the whole assembly (i.e. the arm 36, the plate 80, the structure 35) extremely compact.
  • the configuration described above forms a "profile” coupling between the extension 82 fastened to the upper arm 36 and a seat 81 made in an element (in the described case the plate 80) fastened to the structure 35.
  • the section of the base 82A can be of any shape, e.g. pentagonal, ovoid, elliptic, and the like, and the section of the hole 81 must be complementary therewith.
  • Figure 6 shows another embodiment of the means stabilizing the blade 40 raised, non-use position, in a section view taken along a plane perpendicular to the upper arm 36.
  • the stabilizing means include a plate 101, which is fastened to the upper part of the structure 35 and has a overturned "U"- shape with divergent wings, to which panels 102A, 102B made of a suitable synthetic or gum-like material are fastened.
  • the panels 102A, 102B form a "profile" seat, which couples with a complementary wedge-like extension 103 fastened to the upper arm 36.
  • Pads 103A, 103B made of e.g. polyzene are fastened to the outer sides of the wedge.
  • the upper arm 36 cannot oscillate about its axis, which stabilizes the non-use configuration of the upright 41 - blade 40 assembly.
