Definitions

  • This invention relates to a support for a cutting head and has particular application to a cutting head which can be utilised In pruning and coppicing trees in a plantation or in a dense vegetation situation.
  • a particular application of the invention relates to use in plantations in trimming branches from trees and/or reducing the number of stems resulting from the coppicing from the stump of a tree.
  • the usual method of undertaking this action is have a chain saw operator manually remove the requisite branches and/or stems. This requires the operator to walk through the plantation carrying the chain saw and operate on each tree and can be a very labour intensive and hazardous activity.
  • this then enables the action of removal of branches and stems to be effected using a vehicle having an articulated boom without the need for the operator to use a cutting tool and manually apply the cutting tool to the tree.
  • the invention resides in a cutting head support which is adapted to be mounted to an articulated boom, the cutting head support comprises a base which in use is to pivotally support a cutting tool through a mounting such that the cutting tool extend outwardly from one side of the base, the mounting pivotally supported from the base, the mounting associated with a link member pivotally mounted between the mounting and a pivot, the link member supported from the mounting at a position radially displaced from the pivot axis of the mounting in opposed relation to the cutting tool, wherein the pivot is spaced from the mounting, the link member being pivotally and slidably supported on the pivot, a drive means capable of causing angular displacement of the link member about the pivot resulting in the rotation of the mounting to cause angular displacement of the cutting tool.
  • the mounting is provided with a radial portion and the link member is pivotally mounted to the radial portion.
  • the drive is adapted to cause the spacing between the radial portion and the pivot to vary as a result of said displacement.
  • the invention resides in a cutting head support which is adapted to be mounted to an articulated boom, the cutting head support comprising a base which in use is to pivotally support a cutting tool through a mounting such that the cutting tool extends outwardly from one side of the base, the mounting pivotally supported from the base, the mounting associated with a linkage comprising a radial portion intended in use to extend in opposed relation to the cutting tool, an elongate link member pivotally mounted at one end to the radial portion, the elongate link member having a longitudinal slot, a pivot is spaced from the radial portion, the pivot being received in the slot whereby the link member is both pivotally and slidably supported on the pivot, a drive means mounted between the base and the link member whereby drive means is capable of causing displacement of the link member about the pivot resulting in the rotation of the mounting to cause angular displacement of the cutting tool.
  • the drive comprises a drive member located to one side of the link member and connected between the base and the link member.
  • the drive comprises a pair of drive members located to each side of the link member and connected between the base and the link member.
  • the connection of the drive means to the link member is located between the mounting and the pivot.
  • the drive members comprise fluid operated rams which are cooperatively interconnected to be able to cause said displacement.
  • the cutting tool comprises a chain saw bar which is supported at one end from the base and extends from the base.
  • the cutting tool is driven from a second drive means supported from the cutting head support.
  • Figure 1 is a schematic plan view of a cutting head support according to the embodiment.
  • Figures 2, 3 and 4 are plan views of the cutting head support illustrating the pivotal movement of the cutting tool on the cutting head support.
  • the embodiment is directed to a support for a cutting head which is capable of being mounted to the end of the articulated boom (not shown) which is supported from a vehicle.
  • the articulated boom is of the same form as that utilised with excavation buckets and the like and the vehicle can comprise a specialised vehicle or may be one such as an agricultural tractor having a 3-point linkage which is able to support the arm.
  • the boom comprises a pair of arms pivotally interconnected whereby one end of the pair of arms is pivotally supported from the vehicle to be about pivotable about a both a substantially transverse axis and an upright axis of the vehicle and which has the appropriate drives for controlling the movement in each axis.
  • the arms are also interconnected by a hydraulic cylinder or like which is capable of causing pivotal movement of the outer arm with respect to the inner arm while the outer end of the outer arm pivotally supports a support element the movement of which is controlled by a further hydraulic cylinder to vary the attitude of the support element with respect to the outer arm.
  • the cutting head support is adapted to be mounted to the support element of the boom and comprises a base 11 formed with a central portion 13 and a pair of laterally extending portions 15 and 17.
  • One end of the central portion 13 supports a mounting 19 which is intended to support a cutting tool.
  • the cutting tool 21 comprises a chainsaw bar.
  • the chain saw bar is driven from a hydraulic drive motor 23 or a like drive which is capable of driving the chainsaw bar 21 and which is supported on the mounting.
  • the mounting 19 is pivotally supported from the central portion 13 of the housing to be rotatable about a first pivot 25 whereby rotation of the mounting results in angular displacement of the cutting tool through approximately 180°.
  • the mounting 19 is associated with a linkage which comprises in part a radial arm 27 which extends from the mounting 19 in opposed relation to the cutting tool 21.
  • the linkage also comprises in part an elongate link member 29 which is pivotally supported at one end from the radial arm 27.
  • the other end portion of the link member 29 is provided with an elongate slot 31.
  • the linkage further comprises a second pivot 33 towards the other end of the central portion 13.
  • the slot is engaged with the second pivot and as a result the elongate link member is slidably and pivotally supported upon the second pivot.
  • Each lateral portion 15 and 17 of the housing 11 supports a fluid operated ram 35 and 37 respectively.
  • the outer ends of the rams mounted at one end to the outer end of the respective lateral portion 15 and 17 and are pivotally connected at the other end to the link member 29 at a position intermediate of the radial arm 27 and the adjacent end of the slot 31.

Abstract

La présente invention concerne un support de tête coupante (11) adapté de manière à pouvoir être monté sur un bras articulé. Le support de tête coupante est constitué d'une base (13) qui, lors de son utilisation supporte de manière pivotante un outil coupant (21) à travers un montage (19) de sorte que l'outil coupant s'étend vers l'extérieur depuis un côté de la base. Le montage est fixé de manière pivotante depuis la base et il est associé à un élément de liaison (29) monté de manière pivotante entre le montage et un pivot (33). L'élément de liaison est fixé au montage en un point radialement excentré par rapport à l'axe du pivot du montage et en opposition par rapport à l'outil coupant, le pivot étant séparé du montage. L'élément de liaison est fixé de manière pivotante et coulissante au pivot. Le support de tête coupante comprend des moyens d'entraînement (35, 37) capables de provoquer un déplacement angulaire de l'élément de liaison autour du pivot résultant de la rotation du montage ce qui provoque un déplacement angulaire de l'outil coupant.
