  • Figure 10 is a view similar to Figure 9 with the exception that the frame is depicted in a second (folded) position;
  • FIG 11 is a schematic fragmentary view of part of the mobile frame of Figure 9.
  • the mobile frames according to the two embodiments are arranged to carry elongated ground working tools of the type disclosed in International Application No. PCT/AU87/ 00183. However, it will be understood that the frames may be arranged to carry, any suitable ground working tools or other devices such as spray nozzles.
  • the mobile frame according to the first embodiment is designated generally by reference numeral 10 and includes a longitudinal member 11 which provides a draw bar having a forward end 13 arranged for detachable connection to a towing vehicle (not shown) such as a tractor.
  • the longitudinal member 11 is supported adjacent its trailing end on ground engaging wheels 15.
  • the mobile frame further comprises two boom sections 17 disposed one to each longitudinal member, as best seen in
  • Each boom 17 is pivotally mounted at its inner end on the longitudinal member for pivotal movement between a first (working) position in which '- e boom section extends outwardly of the longitudinal member (as shown in Figure 1) , and a second (folded) position in which the boom section lies substantially alongside the longitudinal member (as shown in Figure 2) .
  • a first pivot means 19 connects each boom section 17 at the inner end thereof to the longitudinal member.
  • the first pivot means 19 comprises a frame having a central element 21 which is slidably mounted on the longitudinal member 11 for movement therealong and a pair of lateral elements 23 which are supported on the central element 21.
  • Each lateral element 23 includes a pivot point 25 to which a respective one of the boom sections 17 are pivotally connected at its inner end for pivotal movement about a substantially vertical axis between the first and second positions, as previously described.
  • a support beam 27 extends between the longitudinal member 11 and each boom section 17 (as best seen in Figure 1 of the drawings) and is elevated with respect to the longitudinal member and the boom section (as best seen in Figure 3) .
  • Each support beam 27 and the respective boom section 17 are interconnected at 29 for pivotal movement about a substantially vertical axis. More particularly each support beam 27 is connected at its outer end at 29 to the respective boom section 17 by way of a turntable 41 which is mounted on a support 43 fixed to and extending upwardly from the boom section.
  • the upstanding support 43 accommodates the difference in elevation between the boom seciton and support beam and the turntable 41 accommodates pivotal movement therebetween.
  • a second pivot means 31 connects the support beams 27 at the inner ends thereof to the longitudinal member 11 for pivotal movement about respective vertical axes.

  • At the extremities of the transverse member 35 there are provided pivot points 39 to which the inner ends of the support beams 27 are connected.
  • Movement of the boom sections between the first (working) and second (folded) positions is controlled by movement of the first pivot means 19 axially along the longitudinal member 11. While such movement of the first pivot means 19 axially along the longitudinal member 11 can be accomplished in any suitable manner, in this embodiment it is accomplished by means of a power device in the form of a hydraulic ram (not shown) operating between the first pivot means '* and the longitudinal member.
  • the boom sections 17 are supported at their outer ends by castor wheels 45.
  • a support cable 47 extends between the longitudinal member 11 and the outer end portion of each boom section 17, as shown in Figure 1 of the drawings .
  • the support cables 47 serve to stabilise the boom sections when the boom sections are in the first (working) position.
  • each boom section 17 is arranged to support a tool 48.
  • the boom sections 17 are provided with a lift mechanism acting under the control of hydraulic rams 49 operable to lift the tool 48 clear of the ground to facilitate movement of the boom sections between the extended and folded positions-
  • the mobile frame according to the second embodiment is somewhat similar to that shown in the first embodiment, with the exception that there is a further boom section 50 provided on each side of the longitudinal member.

Abstract

Une structure mobile, destinée à soutenir des outils de travail de la terre, comprend un élément longitudinal (11) et deux premières sections de flèche pivotantes (17), l'une de chaque côté de l'élément longitudinal. Un premier organe de pivot (19) relie chaque première section de flèche (17) à l'élément longitudinal en vue d'un mouvement de pivot autour d'un axe vertical correspondant entre une première position dans laquelle chaque flèche s'étend vers l'extérieur par rapport à l'élément longitudinal et une seconde position dans laquelle les sections de flèche sont disposées essentiellement le long de l'élément longitudinal. Ladite structure comprend en outre une paire de premières poutrelles de support pivotantes (27) l'une et l'autre s'étendant entre chaque première section de flèche et l'élément longitudinal. Chaque poutrelle de support (27) et la première section de flèche correspondante (17) sont reliées entre elles en vue d'un mouvement de pivot autour d'un axe vertical. Un second organe de pivot (31) relie les poutrelles de support (27) à l'élément longitudinal (11) en vue d'un mouvement de pivot autour d'axes verticaux correspondants. Un dispositif de transmission mécanique ou autre organe similaire est prévu pour effectuer le mouvement relatif entre le premier organe de pivot et le second organe de pivot le long de l'axe de l'élément longitudinal, permettant ainsi un mouvement de pivot des sections de flèche entre la première et la seconde position.
