Definitions

  • the present invention relates to a loading chute on a snowthrower, slingshot or -schleäsuder, comprising a rotatably mounted about a substantially vertical axis of rotation base part, a stored at this lower chimney part, a pivotally connected to the lower chimney part about a substantially horizontal pivot axis upper chimney part and an independently adjustable discharge flap arranged at the upper chimney part, wherein a drive unit is provided, by means of which the geometry of the loading chimney between an operating position in which the two chimney parts connect substantially continuously for a straight course of the chimney, and a transport position, in which the upper chimney part is folded in the direction of the lower chimney part of this, is changeable.
  • Snow blowers, snow throwers and snow blowers are used, typically mounted on the front of a carrier vehicle, the removal of snow from traffic areas such as roads, runways, track bodies and the like.
  • the snow is usually ejected through a chimney.
  • the chimney In order to influence the direction of throw and the throw height or throw of the snow, the chimney is rotatable about a substantially vertical axis of rotation and has on the other hand at its upper end an adjustable discharge flap.
  • the snow is usually ejected sideways through the fireplace and in a certain Distance range stored laterally from the traffic area to be cleared in the area.
  • a relatively high chimney required, which typically towers at least 2.80 m above the road surface and is referred to as a loading chimney.
  • the loading chute In order for the loading chute not to obstruct passage through low tunnels or under low bridges, it must be possible to reduce its overall height.
  • the snow removal unit can also operate with a loading chute brought into its transport position, wherein even in the lowered position of the upper chimney part, the trajectory of the ejected snow with the discharge flap can be influenced.
  • public prior use Milling Sling KFS 950 Toni Kahlbacher GmbH & Co.
  • a comparatively low discharge chute usually suffices, which, unlike the introductory state of the art, typically comprises three main components, namely one essentially vertical axis rotatably mounted base part, an adjoining this chimney part and arranged at the upper end of the chimney discharge flap (also known, for example, by public prior use of the Milling Sling KFS 950 Toni Kahlbacher GmbH & Co. KG). In such ejection chimneys, the issue of height discussed above is not relevant.
  • the US 4312143 discloses a two-piece chimney, not having a discharge flap, for a snow thrower in which an upper chimney part can be displaced along the lower chimney part between a raised operating position and a lowered non-operating position.
  • a two-piece fireplace without flap is from the AT 390 460 B known, in which case the upper and the lower chimney part are connected to each other via a pivot joint, so that the upper chimney part can be folded down from its upright operating position into a folded non-operating position.
  • the present invention has the object to provide a loading chimney of the type specified, the maximum flexibility in terms of snow ejection (loading on a support vehicle, free ejection into the field with different throw lengths and pitches ) and at the same time outside the use of the snow removal unit can assume a transport position in which the driver's view of the carrier vehicle is impaired as little as possible.
  • the bottom chimney part about a substantially horizontal, to the first pivot axis substantially parallel second pivot axis is pivotally mounted on the base part and that one between the base part and the upper in a loading chimney of the type specified Chimney part acting coupling member is provided, wherein the base part, the lower chimney part, the upper chimney part and the coupling member such elements of a Gelenkvielecks are that a change in the position of the upper chimney part relative to the lower chimney part in a pivoting direction forcibly with a change in the position of the lower chimney part is coupled relative to the base part in the opposite pivoting direction.
  • the Verladekamin invention is characterized in other words by the fact that a kinematic forced coupling between the base part, the lower chimney part and the upper chimney part is provided, which leads to a zigzag folding of the two chimney parts, if the geometry of the loading chute using the drive unit of a extended operating position in a space-saving Transport position is changed.
  • the transport position of the loading chute is accordingly oppositely kinked in two directions, namely in the region of the joint between the base part and the lower chimney part and the other in the region of the joint between the lower and the upper chimney part.
  • the chimney By operating the drive unit, the chimney is erected in a single operation in its extended position in which there is a substantially continuous course both in the region of the transition from the base part to the lower chimney part and in the region of the transition from the lower to the upper chimney part.
  • the position of the discharge flap can be adjusted independently in the operating position of the loading chimney, in particular to adjust the throw to the local conditions.
  • the loading chute according to the invention after folding and erecting by means of a single drive unit (e.g., hydraulic cylinder), is particularly robust and reliable in a technically simple and inexpensive construction, with even a loading chute e.g. with regard to the ejection of snow across noise barriers away is carried out particularly long, not blocked in his folded transport position the driver's view.
  • a single drive unit e.g., hydraulic cylinder
  • the drive unit can, for example, act between the base part and the lower chimney part by a corresponding hydraulic cylinder on the one hand acts on the base part and on the other hand on the lower chimney part.
  • an arrangement of the drive unit Such conceivable that it acts between the lower chimney part and the upper chimney part or between the base part and the upper chimney part.
  • the drive unit is hingedly connected at one end to the coupling member, and that conveniently close to the articulated connection of the coupling member to the base part. This is particularly advantageous when the coupling member comprises a hinged to the base part and the upper chimney part coupling rod.
  • the drive unit can act in particular between the coupling member and the lower chimney part.
  • a - especially exclusively or largely subjected to pressure - coupling rod comprises, the present invention is not limited thereto. Rather, embodiments with only claimed to train coupling links, which may for example be designed as ropes or chains, which can attack on protruding beyond the hinge connection of the two chimney extensions of the respective upper chimney part, can be realized. However, for reasons of accommodating the coupling member is preferred if this, as shown and explained below in the embodiments, a pressure-loaded coupling rod and on the base part, based on the axis of rotation, relative to the articulated connection of the lower chimney portion with the base part is articulated.
  • the base part is made in two parts by comprising a rotary member and an extension connected thereto, wherein the lower chimney part is pivotally connected to said extension about said second pivot axis.
  • the extension is preferably not vertical, but rather slightly inclined in the direction of ejection.
  • the in the Fig. 1 to 3 illustrated snowblower 1 is, apart from the loading chute, constructed in the manner known as such.
  • a blast wheel housing 2 is arranged, in which a rotatably driven blast wheel is received and which has a discharge nozzle 3 directed vertically upwards.
  • Further details of the snow thrower are not relevant to the present invention. In that regard, it is also indicated only schematically and a more detailed explanation dispensable.
  • the loading chute 4 constructed on the discharge nozzle 3 of the blower wheel housing 2 comprises four main components, namely a base part 5, a lower chimney part 6, an upper chimney part 7 and a discharge flap 8 in the flow direction.
  • the two chimney parts 6 and 7 and the discharge flap 8 are in customary running channel-shaped.
  • the base part 5 is rotatable on the ejection nozzle 3 about a vertical axis of rotation stored and, for adjusting the discharge direction, by means of a - not shown - adjustable drive rotatable.
  • the end flap disposed on the upper chimney part 8 is, as is also known as such, for changing the throw or throw height adjustable by means of an adjustment. Visible in this respect are the articulated connection 42 of the discharge flap 8 with the upper chimney part 7 at its upper end and the independent adjustment of the discharge flap 8 about the pivot axis of the articulation 42 serving around drive units 43 in the form of hydraulic cylinders 44th
  • the upper chimney part 7 is pivotably connected to the lower chimney part 6 about a horizontal pivot axis 9 pivotally.
  • the inside width of the upper chimney part 7 is slightly larger than the width of the lower chimney part 6, so that tabs 10 of the upper chimney part 7 surround the lower chimney part 6 laterally.
  • the lower chimney part 6 is in turn pivotally connected to the base part 5 about a second, also horizontal pivot axis 11, wherein the two pivot axes 9 and 11 are parallel to each other.
  • the determined by the second pivot axis 11 joint 12 is arranged on the closed side of the channel-shaped lower chimney part 6.
  • an abutment 17 is arranged on the - relative to the vertical axis of rotation - the joint 12 opposite side of the base part 5, an abutment 17 is arranged.
  • a coupling member 19 from hinged.
  • the coupling member comprises a coupling rod 20, the free end 21 is pivotally connected to the upper chimney part 7 about a horizontal, in turn to the three pivot axes 9, 11 and 18 parallel pivot axis 22 pivotally.
  • the pivot axes 9, 11, 18 and 22 form the corner points of a through the base part 5, the lower chimney part 6, the upper chimney part 7 and the coupling member 19 defined four-bar linkage.
  • a drive unit 24 in the form of a double-acting hydraulic cylinder 25 is articulated.
  • the other end 26 of the hydraulic cylinder 25 is hinged to the lower chimney part 6 articulated.
  • the base part is made in two parts, in addition to a - not shown - a rotating part associated with this extension 27, with which the lower chimney part 6 is pivotally connected about the second pivot axis 11 pivotally.
  • the extension 27 includes a channel-shaped snow guide 28.
  • a support 29 is further arranged, on which the lower chimney part 6 rests when the loading chute 4 'assumes its (fully folded) transport position.
  • the extension is slightly inclined in the direction of ejection.
  • the lower chimney part 6 In the region of its upper end 30, the lower chimney part 6 a stiffener 31, which comprises a cross tube 32 and two laterally arranged triangular plates 33. On the triangular plates 33, on the one hand, the two hydraulic cylinders 25 engage. On the other hand, passes through the triangular plates 33, the pivot axis 9 of the articulated connection of the upper chimney part 7 with the lower chimney 6.
  • the upper chimney 7 has in turn in the region of its lower end 34 a stiffener 35, which comprises a cross tube 36 and two cheek plates 37. On the cheek plates 37, on the one hand, the two coupling rods 20 engage. On the other hand, passes through the cheek plates 37, the pivot axis 9 of the articulated connection of the upper chimney part 7 with the lower chimney 6.
  • the length of the coupling rod 20 via threaded heads 45 is adjustable.
