At a second end 36 is the Cylinder 32 with both the rocker 26 and with a Tool, such as a blade 38, connected such that the Driver of the tractor a desired movement can perform. This can also be a different tool than the Blade 38 in conjunction with the described Charger device 20 are operated.
  • the charger device 20 is with the frame 22 at respective front and rear Frame areas 40, 42 connected. Since the charger device 20 and the frame portions 40, 42 to which it is connected, arranged symmetrically to a longitudinal axis "X" of the tractor are, only the left side of the front and rear Frame portions 40, 42 of the frame 22 described in more detail.
  • FIG. 1 shows how the charger device 20 in FIG operated in a first mode, in which this completely with connected to the frame 22 of the tractor.
  • the mast 24 of the charger device 20 has an upper and a lower end region 44, 46. At its bottom End portion 46, the mast 24 is a substantially open trained Ausschalung on, so that a receiving area 48 formed with the rear frame portion 42 of Frame 22 can be brought into connection (see Figures 1 to 4).
  • the rear frame portion 42 the frame 22 is partially formed in the form of a tube 50.
  • the tube 50 has a Mounting plate 54 for attachment to the body of the tractor on.
  • the tube 50 alternately rising and falling areas 58, 60.
  • the tube 50 furthermore, a cylinder bolt 62 attached thereto.
  • the strut 28 is pivotally connected to the mast 24 at a point "d" mounted and extends laterally from it.
  • the strut 28 comprises a ground engaging part, which may be referred to, for example, as foot-like part 66 is formed.
  • the foot-like part 66 comprises at least one upper and lower connecting element 68, 70, which are arranged spaced from each other and to Connection to the front frame portion 40 of the frame 22nd serve, as shown in Figures 1 to 4 and 7.
  • the lower connecting element 70 has a round and upper connecting element 68 has a rectangular cross-section.
  • the lower Connecting element 70 is formed as part of a bracket 78.
  • the bracket 78 is pivotally attached to the foot-like portion 66 at one Point "g" mounted, allowing a movement relative to the front Frame part 40 of the frame 22 during attachment and removal of the Charger device 20 is enabled.
  • bottom link 70 with a pair of laterally opposite and upwardly directed tabs 80 connected.
  • the strut 28th a useful clamping force on the front frame area 40 of the frame 22.
  • the Car drivers generally be sure that the Charger device 20 even under the heaviest working conditions not released from the tractor.
  • a is Cam mechanism 82 pivots about this point with the strut 28 connected.
  • the cam mechanism 82 includes a body 84 with an actuating element, which exemplifies a handle 86, for rotating the body 84 relative to the point "h” in FIG Forward or backward direction, is formed as is shown in detail in Figures 5 and 6.
  • the body 84 further includes a housing 88 as in FIG. 5 shown, which has an extendable part, for example a bolt 90, receives.
  • the bolt 90 is relative to the Housing 88 adjustable positionable to make contact with an arcuate contact surface 92 on the mast 24 produce or to avoid.
  • the cam mechanism 82 is in communication with a Arret réellesarm 94 shown, both of the driver's seat can be reached from the tractor.
  • the locking arm 94 is formed for example in the form of a leaf spring.
  • the Arret réellesarm 94 is fixed with strut 28 is pinned at points "i" and at one point "j" adjustable in the body 84 of the cam mechanism 82nd fitted, wherein the fitting takes place by means of a nose 96, which extends from a side surface 98 of the body 84.
  • the cam mechanism 82 is in Connection with a spring 100.
  • the spring 100 is in one Interior 102 of the (cam) body 84 housed and with the Strut 28 connected at a point "k" to hold one Positioning relative to the point "h” in reverse or Forward direction support.
  • the bolt 90 is in one to the contact surface 92 abutting position, when the handle 86 to is twisted behind the point "h".
  • a position is characteristic of a first mode in which the Charger device 20 completely with the frame 22 of the Tug is engaged, where, as already mentioned, the Mast 24 in the rear frame portion 42 of the frame 22nd fitted and the foot-like portion 66 of the strut 28 in the front frame portion 40 of the frame 22 is clamped.
  • the driver can determine the position of the driver Adjust the head of the bolt 90 so that it is in the Essentially with the contact surface 92 of the mast 24 in engagement occurs.
  • the possibility of the length of the bolt 90 in the housing 88th to be able to adjust, allows the driver, the Adjusting the position of the mast 24 relative to the strut 28.
  • a Such possibility is in the cases of advantage in which Cause wear and tear, be it between the foot-like part 66 and the front frame part 40 of the frame 22 or the rear frame part 42 of the frame 22 and the Receiving area 48 or in the leadership of the bolt 90 on the Bearing surface 92, that is the holder of the charger device on the frame 22 can solve.
  • FIG. 1 it can be seen that the first mode is present when (A) the bolt 90 substantially with the contact surface 92 of the Mastes 24 is in contact and (b) the receiving area 48 of the Mast 24 completely on the rear frame portion 42 of Frame 22 rests. It is intended that the driver the locking arm 94 in the position shown in Figure 1 brings about the position of the body 84 of the cam mechanism 82nd and thus the bolt 90 to hold.
  • FIGS. 2 to 4 show a second mode which relates to the removal of the charger device 20 from the tractor.
  • a first Step for disassembling the charger device 20 of the locking arm 94 is solved by this at its handle 104 (see FIG 5) pulled outward from its fitting with the nose 96 becomes.
  • the handle 86 can be completely in Forward direction relative to the point "h" to be moved.
  • These Forward movement of the handle 86 rotates the body 84 of the Cam mechanism 82 such that the bolt 90 from his Contact position with the contact surface 92 of the mast 24 brought becomes.
  • a End portion 106 of the body 84 of the cam mechanism 82 in a Stop position with the contact surface 92 of the mast 24th brought.
  • Step reaches when the driver the lifting cylinder 64th fully extended.
  • the foot-like part 66 is in an im Substantially vertical position relative to the frame 22 and to Soil surface brought.
  • the receiving area 48 of the dissolves Mast 24 from the rear frame portion 42 of the frame 22 as it is shown in more detail in FIG.
  • Receiving portion 48 of the mast 24 has a first and a second groove 108, 110.
  • the first groove 108 extends from the point “1" to to the point “m” and has a surface with which the attached cylinder pin 62 comes into contact when the mast 24 mounted on the rear frame portion 42 of the frame 22 is. Such a contact is particularly in Figure 10 in Point "1" shown.
  • Fig. 11 shows a position between the points "l" and "m”, such a position occurring when the charger device 20 is dismantled from the frame 22. It will clear that the patch cylinder pin 62 is not on a End point of the groove 108 is present. As a result, the Mast 24 relative to the rear frame part 42 of the frame 22nd move.
  • the second groove 110 provides clearance for the rising Area 58, so that it is movable when the Charger device 20 to / from the rear frame portion 42 of Frame 22 is grown / dismantled. Furthermore, it is for One skilled in the art will recognize that a contact between the first groove 108 and the attached cylinder pin 62 serves, essentially over-turning of the mast 24 away from the rear frame portion 42 of the frame 22 to avoid. In addition, such overwinding is also characterized avoided, as shown in Figure 10 that the rising area 58 against an inner segment 113 of the Recording area 48 strikes.
