Definitions

  • the present invention relates to an apparatus for clearing snow from road edges and the like.
  • snowplows are generally used to clear snow from the roads of urban areas; said snowplows are provided, at the front, with a wedge-shaped device which pushes the snow to the sides of the road.
  • Rotary snowplows are furthermore known which are provided with a milling roller which removes the snow from the road and conveys it to launch tube.
  • Such known snowplows are however rather rigid in their use.
  • the snow removed from the road is in fact accumulated along the road edges, forming a barrier which can obstruct access to pedestrian walkways, gates, garages and the like.
  • the fact is furthermore particularly complained that the snow can laterally and upwardly cover the bins used for collecting refuse, the use whereof must instead be ensured due to obvious hygiene problems.
  • the US patent No. 4.480.397 discloses a snowblower mounted on a truck so as to be raised and lowered and swivelled between an operative lateral position and an inoperative rearward position.
  • the known snowblower cannot be used for removing snow from restricted areas such as between parking cars, or in front of garage entrances or from the cover of refuse containers, which are usually arranged along the road edges.
  • the US patent No. 3.574.939 discloses a rotor type tool supported on a tractor by means of a mechanism permitting adjustement of the tool with respect to the tractor and to the soil.
  • orientation of the tool is achieved by means of a gear casing which renders the mechanism not adapted to rough working conditions as it occurs during road clearing.
  • the aim of the present invention is to solve the above problem by providing an apparatus which allows to clear snow from road edges or sides at refuse bins, pedestrian passages and the like.
  • an object of the present invention is to provide a snow-clearing apparatus which is simple in concept, safely reliable in operation and versatile in use.
  • the snow-clearing apparatus is generally indicated at 1 and is applied behind a vehicle 2 (figure 3) which is adapted to act as tractor and has a mechanical power take-off.
  • vehicle 2 (figure 3) which is adapted to act as tractor and has a mechanical power take-off.
  • the use of a vehicle with a hydraulic three-point lifter, indicated at 3 in the drawing, is conveniently provided.
  • the apparatus 1 is provided with an oil tank 4 which is rigidly associated with the three arms of the lifter 3 of the tractor.
  • the tank 4 has a particularly strong structure and is upwardly provided with a hydraulic unit 5 which has a pair of tandem pumps supported by the power take-off and actuated thereby through an adapted multiplier. Said unit is commercially available and is therefore not described in detail.
  • An arm 6 is rigidly fixed to the rear face of the tank 4 and is inclined on a vertical plane.
  • a supporting plate 8 for a telescoping beam 9 is articulated on a pivot 7 at the top of the arm 6.
  • the telescoping of the beam 9 is actuated by a jack 10 which is fixed longitudinally to said beam.
  • Said beam 9 can rotate angularly on its vertical plane which is transverse to the direction of advancement of the tractor 2 upon the actuation of a lifting jack 11 which is articulated to the lower end of the arm 6 at a pivot 12 and to the beam 9 at a pivot 12a.
  • the beam 9 is guided, during its rotation, within a vertical slot of a guide 13 which is rigidly associated with the tank 4.
  • the telescoping portion 9a of the beam 9 is connected by means of a bracket 14 to the stem 15 of the beam actuating jack 10, and a snow-clearing tool, generally indicated at 16, is articulated to said bracket.
  • Said tool 16 comprises a milling roller 17, of the kind known for use in snow-clearing.
  • a frame 18 supports the milling roller 17 so as to allow rotation thereof around a horizontal axis, with the frame 18 defining a protective housing for said milling roller and rearwardly supporting a hydraulic motor element 19 for actuating said roller.
  • the frame 18 is upwardly provided with a duct 20 for expelling the jet of snow, and a launch tube 21 is mounted thereon and is axially rotatable so as to allow the jet of snow to be launched in the desired direction.
  • the frame 18 supports a pivot 23 (figure 1) for articulation to a column 24 supporting the beam 9; the pivot 23 has a horizontal axis and is perpendicular to the axis of the milling roller 17.
  • the frame 18 is rotatable about the pivot 23 by actuating a jack 25 which is pivoted to the column 24 at one end 26 and on the ledge 22 at the opposite end 27.
  • the column 24 is angularly rotatable about its own vertical axis within a sleeve 28 which is supported at the free end of the telescoping portion 9a of the beam 9.
  • the angular rotation of the column 24 is actuated by a jack 29 which is articulated, at one end, to a fork-like arm 30 which extends horizontally and is rigidly associable to the portion 9a of the beam 9, as will be explained hereinafter; the stem 29a of the jack 29 is instead articulated to a lever 31 which is radially rigidly associated with the column 24.
  • a safety device is conveniently interposed between the beam 9 and the coupling of the tool 16; said safety device comprises a pair of plates 32, 33 which are arranged facing one another and are rigidly associated through a plurality of shear pins 34.
  • the plate 32 is provided, on its opposite faces, with a tang 35 and with a pivot 36 which are mutually coaxial.
  • the tang 35 engages a seat 37 which is defined frontally to the portion 9a of the beam 9 and is locked by a transverse shear pin 38; the pivot 36 crosses the plate 33 and in turn engages a sleeve 39 which is rigidly associated with said plate 33.
  • the sleeve 28 of the column 24 and the supporting arm 30 of the jack 29 are rigidly associated with the plate 33.
  • the snow-clearing tool 16 can work in all directions and positions, both in the direction of advancement of the tractor 2 and transversely thereto, as can be seen respectively in figure 1 and in figure 2.
  • the hydraulic unit 5 By means of the hydraulic unit 5, it is in fact possible to act on the hydraulic jacks 11, 25 and 29 so as to obtain the desired working position.
  • the jack 29 allows, by acting on the lever 31 which is rigidly associated with the column 24, to angularly rotate the tool 16 between a working position of the roller 17 which is perpendicular to the direction of advancement of the tractor (figure 1 corresponding to the position of tube 21 and lever 31 shown with continuous line in figure 4) and a parallel working position, as illustrated in figures 2 and 3 with tube 21 and lever 31 in the position shown with broken lines in figure 4.
  • the tool 16 is raised by inclining the beam 9 by means of the jack 11.
  • the jack 25 which controls the rotation of the frame 18 with respect to the column 24, it is possible to restore the horizontal position of the axis of the roller 17.
  • the jet of snow can be directed exactly in the desired direction.
  • shear pins 34, 38 allows the impacts suffered by the milling roller or by the frame of the tool to be dampened both in the direction of advancement and transversely thereto.
  • the materials employed, as well as the shapes and dimensions, may be any according to the requirements.
