Definitions

  • the invention relates to a snow plow for mounting on the front of a carrier vehicle, to the support plate of which a snow plow-side device plate is fastened, which is connected via a frame part to the ploughshare in such a way that it can be raised and lowered relative to the device plate by means of a lifting and swiveling drive , and is pivotable to both sides.
  • the frame part is designed as a parallelogram of the handlebars, an upper and a lower pair of handlebars being articulated on the one hand on the implement plate and on the other hand on the ploughshare.
  • the ploughshare is held in relation to the vehicle or the implement plate or moved by means of a hydraulic lifting cylinder which is between the implement plate and the lower pair of links is supported and by means of two hydraulic swivel cylinders, which are supported between the implement plate and the back of the ploughshare.
  • the tension occurring in the hydraulic cylinders and in the articulation elements during the lifting or lowering process is avoided by a control valve which responds depending on the pressure build-up in the lifting cylinder and, as a result, the swivel cylinder is briefly relieved of pressure.
  • a relief process can be repeated several times during a lifting / lowering movement; it runs automatically and allows the swivel cylinders to be adapted to the respective lifting height without the swivel cylinders being depressurized.
  • the invention has for its object to avoid the undesirable blocking of the lifting movement by the pressurized pivot cylinder and the associated high loads on the hydraulic drive connections and the mechanical suspension of the ploughshare by creating a simple drive and movement system.
  • This object is achieved in that the frame part is guided in a vertical guide provided on the device plate, the lifting drive between the frame part and device plate, the pivot drive between the frame part and ploughshare is supported.
  • the invention makes use of the consideration that, by eliminating a mutual influence of the lifting / lowering movement on the one hand and the swiveling movement on the other hand, each type of movement can be realized without restriction.
  • the required height of the frame can be raised and lowered in a vertical guide; by the fact that the swivel drive sits on the frame part, there is no need to tune the drives for the different types of movement.
  • pressure fluctuations in the hydraulic system caused by the mere movement are avoided. In this way, the loads acting on the frame part itself can be calculated, with the result that deformations due to overstressing are ruled out if the construction is correctly designed.
  • the frame part has guide strips running on both sides in a vertical plane, which are guided in associated guide rails attached to the device plate. This results in a sufficient leadership length for controllable managers.
  • the guide strips are designed to bulge out to the side.
  • the frame part can rotate to a limited extent about a horizontal axis running in the longitudinal direction of the vehicle in accordance with the crowning of the guide strips.
  • An advantageous embodiment of the frame part is characterized in the subclaims 6 to 8.
  • the stops can be provided with buffers made of rubber-like material at their free ends.
  • the designer is free to choose the suitable type of drive.
  • the drive is proven by means of a hydraulic swivel cylinder and a hydraulic lifting cylinder, the former being articulated between the frame part and ploughshare, the latter being articulated between the frame part and the implement plate, in accordance with the invention.
  • motorized drives are also possible, for example electrical drives, which control the respective movement sequence via gear elements.
  • the representation acc. Fig. 1 shows a top view of the back of the ploughshare 1, which is composed in the horizontal direction of several share segments, of which only the middle share segment 2 is shown completely.
  • the ploughshare 1 is movably suspended on a rigid plow frame 5 via handlebar connections 3 and tension springs 4.
  • the plow frame 5 in turn is pivotally mounted about vertical pins 6 on the front corner of a rigid frame part 7.
  • the frame part 7 is composed of an upper triangular frame 8, a lower triangular frame.
  • men 9 Fig. 2 and other vertical and horizontal frame parts. 2
  • the front corners of the two triangular frames 8, 9 are connected to one another by a vertical web 10, to which a vertical plate 11 is fastened.
  • the plate 11 carries brackets 12 with vertical spacing with vertical, mutually aligned bores, in each of which a pin 6 is rotatably received.
  • the pins 6 are fastened to the inner sides of an upper and a lower hollow profile 13, which form the plow frame 5 in connection with vertical struts, not shown.
  • the vehicle-side end of the two triangular frames 8, 9 consists of a closed rectangular frame with an upper cross strut 14, a lower cross strut 15 and vertical, lateral struts, which a gem.
  • Fig. 31 form left guide bar 16 and a right guide bar 17.
  • turn signal inner web 18 and a right inner web 19 provide additional stiffening of the rectangular frame and also serve as articulation points for the vehicle-side ends of two pivot cylinders 20, 21. 23 braced.
  • Thenikeckrahmen mentioned has on its upper side a Ver - lengthening, consisting of two obliquely towards the center extending supporting beams, namely a gem.
  • a lifting cylinder 27 is connected in an articulated manner to the crossbeam 26 with an upper link plate, through which a pivot pin 29 is inserted; with its lower ... Articulated bracket 30, the reciprocating piston 27 is connected via a bolt 31 to a device plate 34, on which lateral guide rails 32, 33 with a U- shaped cross section are fastened.
  • the left guide rail 32 serves to receive the left guide bar 16 of the frame part 7; the right guide rail 33 is shown cut open, so that the spherical design of the right guide bar 17 guided therein can be seen.
  • the left guide bar 16 is correspondingly spherical, so that the entire frame part 7 within the guide rails 32, 33 can be pivoted to a limited extent in both directions of rotation about an axis perpendicular to the plane of the drawing sheet.
  • the guide rails 32, 33 have at their upper end inwardly bent legs 35, 36 there is a corresponding limitation of the vertical lifting movement of the frame part 7, the support beams 24, 25 extending the frame part 7 upwards from lay against the inwardly bent legs 35, 36 of the two guide rails 32, 33.
  • the device plate 34 has on its side facing the front 37 of the vehicle two hook-shaped lugs 38, which engage in corresponding pockets 39 on the side of the vehicle-facing support plate 40 centering from above, so that the devices plate 34 and the support plate 40 lie flat against each other.
  • the lifting cylinder 27 is arranged approximately vertically and at a distance from the device plate 34. To bridge the distance, two bearing plates 41 are provided on the underside of the device plate 34; the upper link plate 28 of the piston 42 of the lifting cylinder 27 is articulated between corresponding bearing plates 43 which are fastened to the crossbar 26 of the frame part 7. Accordingly, an extension of the lifting cylinder causes the frame part 7 to be raised, while a shortening of the lifting cylinder results in a lowering movement of the frame part 7.
  • the swivel cylinders 20, 21 are articulated with their front ends to joint plates 44 (FIG. 1) of the plow frame; with their other ends on the vehicle side, the pivot cylinders 20, 21 are articulated on further joint plates 45, which are fastened to the vertical inner webs 18, 19 of the frame part 7.
