Definitions

  • the invention relates to a clearing blade for a snow groomer which comprises a central part and two side parts which can pivot relative to the central part.
  • a snowcat in the form of a PistenBully 600 is known by the applicant.
  • the known snow groomer has a three-part clearing blade on the front side, which comprises a central part and two side parts which are mounted on opposite sides so as to be pivotable about a vertical axis relative to the central part.
  • the dozer blade is releasably attached to a front support which can be adjusted with the aid of hydraulic adjusting means in such a way that the dozer blade can be raised, lowered, tilted and tilted.
  • the two side parts are pivoted relative to the central part via hydraulic actuating means assigned to the clearing blade.
  • electrohydraulic actuators are provided which are controlled from the driver's cab via an actuating element in the form of a joystick.
  • an actuating element in the form of a joystick.
  • the object of the invention is to create a clearing blade of the type mentioned at the outset which enables simplified operation by a driver of the snow groomer.
  • the object on which the invention is based is achieved in that a side contour of each side part is designed in such a way that in a clearing position it forms a straight cutting edge over its entire height.
  • This makes it possible to cut particularly precise, straight contours in the snow to be processed.
  • This can be used in a particularly advantageous manner in the creation of a fun park by means of a snowcat provided with such a clearing blade.
  • the straight cutting edge runs in the clearing position in which the respective side part is positioned obliquely forward relative to the central part, advantageously - relative to a local coordinate system of the clearing blade - in the vertical direction of the clearing blade, as long as the clearing blade is in a horizontal position.
  • the object underlying the clearing blade of the type mentioned at the outset is also achieved in that the central part is provided with a rearwardly protruding cutting and shaped profiling in the area of a lower rear edge facing the driver's cab, which extends over the entire length of the central part.
  • the solution according to the invention enables shaping, scraping, compacting or cutting the snow surface even when the snowcat is reversing. This solution can also be used in a particularly advantageous manner for a snowcat that is tailored to the requirements of fun park designs.
  • the side parts are provided in the area of a lower rear edge facing the driver's cab with a rearwardly protruding cutting and shaped profiling, which continues in the aligned position of the side parts relative to the central part in a line with the cutting and shaped profiling of the central part .
  • the entire width of the clearing blade, including the central part and side parts is provided for the desired processing of the snow surface when a corresponding snowcat is reversing.
  • the side parts and the middle part can be aligned in a common plane in such a way that they are aligned with one another in such a way that the rear edges of the side parts and of the middle part are also aligned with one another in a straight line.
  • the cutting and shaped profiles of the middle part and the side parts can be formed by webs or cutting edges that are continuous over the entire length. Alternatively, it is also possible to provide the cutting and shaped profiles with corrugated or tooth row profiles or similarly designed, alternating profiles.
  • a snow groomer P for creating a fun park has according to the Figures 1 to 6 a dozer blade 1 on.
  • the clearing blade 1 comprises a central part 4 and two side parts 5, which are pivotably mounted on opposite sides of the central part 4.
  • the side parts 5 are each pivotably mounted on the central part 4 about a pivot axis extending in the vertical direction of the clearing blade 1.
  • the snow groomer P itself has a front support F for holding the clearing blade 1, to which the middle part 4 of the clearing blade 1 is detachably attached via a suspension device 13.
  • the front support F can be raised, lowered, tilted up or down relative to a vehicle transverse axis, pivoted about a central vehicle longitudinal axis or inclined about a vertical vehicle axis via hydraulic actuating means 15 in the form of single or double acting hydraulic cylinders.
  • the clearing blade 1 In the assembled state, the clearing blade 1 is firmly connected to the front carrier F, so that an adjustment of the front carrier F inevitably brings about a corresponding adjustment of the clearing blade 1.
  • the clearing blade 1 has two further hydraulic adjusting means 6 in the form of double-acting hydraulic cylinders which are used to control the side parts 5. In each case a hydraulic adjusting means 6 extends between a corresponding articulation on the central part 4 and a boom on the side part 5.
  • the hydraulic adjusting means 6 in the form of the hydraulic cylinder is provided with two connections for corresponding hydraulic lines in order to apply hydraulic pressure both for retraction and for a To enable extension of the hydraulic cylinder.
  • This is understood as the double-acting hydraulic cylinder.
  • only the direction of extension or the direction of retraction is pressurized.
  • the opposite direction of movement of the hydraulic cylinder is then carried out by simply releasing the hydraulic cylinder.
  • Both the hydraulic adjusting means 6 for the side parts 5 and the hydraulic adjusting means 15 for adjusting the front support F of the snow groomer P, to which the clearing blade 1 is attached, are actuated by electrohydraulic actuators H ( Fig. 1 ), of which the Fig. 2 only an electrohydraulic block controlling the hydraulic actuating means 6 for the side parts 5 is shown.
  • the electrohydraulic actuators H are connected to the hydraulic actuating means 6, 15 via hydraulic lines 10.
  • the electro-hydraulic actuators H are controlled by an electronic control unit S ( Fig. 1 and 2 ), which can be activated via at least one control line E by at least one actuating element 3 of a joystick 2 within a driver's cab of the snow groomer P.
  • the corresponding actuating element 3 is actuated by a driver or another operator of the snow groomer P in order to trigger a desired control function of the electronic control unit S by means of a corresponding control signal via the control line E.
  • the electronic control unit forms an electronic control device with at least one microprocessor, which is part of an operating system of the electrical control unit S.
  • Several control functions for adjusting the middle part 4 and / or the side parts 5 are programmed in the electronic control unit S, each of which activates the hydraulic adjusting means 15 of the front support F and / or the hydraulic adjusting means 6 for the side parts 5 between a starting position and a desired end position cause. Both starting and end positions do not necessarily correspond to the mechanically determined end stops of the hydraulic actuating means 6, 15 of the front support F and the side parts 5.
  • the starting and end positions correspond to defined positions of the clearing blade 1, in which advantageous processing functions of the clearing blade 1 such as a snow clearing function, a shaping and cutting function for radio parking structures can be achieved when the snow groomer P drives forwards or backwards or overpasses in rest or transport positions of the clearing blade 1.
  • a corresponding control function is triggered in a simple manner by an operator by briefly pressing the corresponding actuating element 3 in the manner of a key or button, whereby the corresponding control function is activated via the control line E in the electronic control unit S, which is then activated according to the programming made expires.
  • Corresponding control functions can already be implemented in the operating system of the electronic control unit S by the manufacturer.
  • an input unit can be connected to the electronic control unit S, via which individual control functions can be programmed by the user.
  • FIGS Fig. 2 the hydraulic adjusting means 6 assigned to displacement sensors 7, which are connected to the electronic control unit S via signal lines 9.
  • each swivel hinge of each side part 5 is assigned an angle sensor system 8 relative to the middle part 4, which angle sensor system is also connected to the electronic control unit S via a respective signal line 9.
  • the electronic control unit S can regulate the hydraulic actuating means 6 via the correspondingly recorded path or angle signals by comparing the actual values arriving through the signal lines 9 with the target values for paths or angles stored in the electronic control unit S and
  • the electrohydraulic actuators H are controlled as a function of these target / actual value comparisons.
  • displacement sensors and / or moving parts of the front support F are also assigned to the hydraulic actuating means 15, in order to enable analog control by the control unit with respect to all essential functional positions of the front support F. It is important to note that only one sensor system, i.e. angle sensor system or path sensor system, is used to control the hydraulic actuating means. is required, since signals from one sensor each are sufficient to be able to determine the adjustment path of the respective hydraulic actuating means with sufficient accuracy.
  • the two side parts 5 are each provided with a cut edge 11 on their side contours lying on the outside relative to the middle part 4, which in a clearing position of the side part 5 relative to the middle part 4 (see in Fig. 3 the left side part 5) form a cutting contour 11 aligned vertically and in a straight line exactly in the vertical direction of the clearing blade 1. Since each side part 5 has a concave contour over its height, this results in a linear position of the side part 5 that is aligned with the middle part 4 in one plane (see in FIG Fig. 4 the right side part 5) a concave side contour through the cutting edge 11.
  • the front view of the clearing blade 1 according to Fig. 3 corresponds exactly to the position of the side parts 5 relative to the middle part 4, as shown in FIG. 34.
  • the middle part 4 of the clearing blade 1 also has, as shown in FIG Figures 5 and 6 can be seen, in the area of its underside a flat shaped surface 14, which continues towards the rear of the middle part 4, ie to the side facing the front support of the snowcat in the assembled state of the clearing blade 1, in a shaped and cutting profile 12, the underside of which continues extends substantially in alignment with the molding surface 14 of the central part 4.
  • the shaped surface 14 extends in one plane over the entire width of the clearing blade 1, but can be profiled in itself in order to achieve a uniformly profiled drawing on the machined, flat snow surface.
  • a small angle is provided between the underside plane of the shaping surface 14 of the central part 4 and the underside plane of the shaping and cutting profiling 12, since when the snow groomer moves forward on the clearing blade 1, only the shaping surface 14 should be in engagement with the snow in order to To prevent the dozer blade from floating up by using too large a contact surface. When driving backwards, however, only the cutting-shaped profiling 12 should intervene in the snow surface. These functions are achieved by the small angle between these lower planes.
  • the shape and cutting profile 12 is, as based on Fig. 5 is recognizable, designed wedge-shaped and forms a cutting edge or cutting point on its rear edge.
  • the shaping and cutting profiling 12 designed in this way on the rear underside of the middle part 4 enables the snow groomer to cut and shape the corresponding snow surface when the snow groomer drives backwards.
  • the shaping surface 14 also serves to compact the snow surface that has been machined by the cutting and shaping profiling 12 and to press it smooth.
  • the blade 1 according to the Figures 3 to 6 also has in the area of the side parts 5 on a rear lower edge similar shape and cutting profiles 12, which in the aligned linear position of the side parts 5 with the shape and cutting profile 12 of the middle part 4 lines.
  • the snow surface can be worked over the entire width of the clearing blade 1 when the snow groomer travels backwards by the rear lower edge of the clearing blade 1.
