Definitions

  • This invention relates to earthworking machines, Agricultural tractors are already known, which have on a single chassis a loading equipment at the front, and, at the rear a retro equipment, i.e. one in which the line of operation of the digging tool is towards the vehicle. It should be understood very easily adaptable to various working conditions, particularly as regards the kinds of work and the types of terrain worked upon.
  • an earthworking machine comprises at least two equipments as defined above mounted respectively at the ends of corresponding beams, the beams themselves being mounted on at least one turret pivotablc about a pivot fixed to a single chassis.
  • the equipment used may befor example a loader-leveller, a "retro" bucket, grab, etc.
  • FIG. I is a side elevation of one embodiment of an earthworking machine of the invention.
  • FIG. 2 is an alternative embodiment of the machine of the invention.
  • FIG. 3 is a further embodiment of the machine of the invention.
  • FIG. I shows an earthworking machine of the invention comprising a single self-propelled chassis I carrying a pivot 2 on which pivots a turret 3 carrying two equipments 4 and 5 and having means for rotating the turret and stopping rotation thereof (not shown).
  • One of the equipments 4 comprises, for example, a retro" bucket 6 and the other equipment 5 comprises a loaderleveller bucket 7.
  • These two equipments are mounted respectively at the ends of beams 8 and 9 fixed to the turret 3 and'preferably substantially symmetrical with respect to the axis it): of the pivot 2.
  • the two beams 8 and 9 thus move in a single vertical plane which contains the axis X): of the pivot 2 and can pivot simultaneously about this axis.
  • the equipments 4 and 5 each constitute a counterweight for the other which is automatically established in the vertical working plane of the equipment concerned.
  • This counterweight is adjustable in reach by manipulating the beam, for example, (8 or 9) and in load by filling to a greater or lesser extent the bucket 6 or 7.
  • the equipment 5 When it is used as a counterweight, the equipment 5 is preferably retracted completely as shown in dotted lines, the bucket 7 being suitably filled. The swing and the area through which this equipment sweeps is thus reduced. This counterweight can thus be rapidly and accurately weighted and the machine balanced.
  • one of the equipments can bear on the ground (as shown in FIG. 1) and thus ensure, by stopping movement of the turret 3, in conjunction with the usual feet 10, an increase in adherence and stability of the machine when the equipment .4 is working.
  • This additional support can also enable the equipment 4 to exert its maximum force on the ground, whatever may be the orientation of the turret 3.
  • the chassis I of the machine can be raised in order, for example, to free it and orientate it in another direction.
  • this arrangement can be mod fied by providing other equipments on beams mounted on the turret 3 and preferably distributed symmetrically with respect to the axis x'x. As was seen above, when one of these equipments is operating, the others are used as counterweights which may or may not be variable, or as additional support or locking members for the turret or the machine.
  • FIG. 2 shows an alternative embodiment of the invention, in which the two beams 8 and 9 carrying the equipments 4 and 5 are mounted on two independent turrets 11 and 12, which are themselves both mounted on the pivot 2. Means (not shown) are provided to drive the two turrets II and 12 in rotation independently of each other and, if necessary, to lock one with respect to the other.
  • This embodiment offers the same advantages as the machine shown in FIG. 1 and provides greater flexibility, particularly as regards the stability of the machine.
  • the equipment 5 can bear on the ground according to the irregularities, the inclination or makeup of the terrain, independently of the zone of operation of the equipment 4, in order to ensure a firm stance for the machine.
  • This equipment 5 can also constitute a counterweight for the equipment 4.
  • FIG. 3 shows another embodiment of the machine of the invention which is similar to that shown in FIG. 2.
  • the two equipments 4 and 5 of the machine are pivotally mounted independently of each other, the two corresponding turrets l3 and 14 being mounted on two separate pivots l5 and 16 fixed to the chassis l.
  • the axes yy and z: of the pivots l5 and 16 are distributed so as to ensure stable balancing and a solid stance for the machine during work carried out by one or other of the equipments.
  • An earthworking machine comprising a chassis, a first turret mounted for rotation about an axis of rotation on said chassis, a first beam means having one end connected to said first turret and extending from said first turret, an earthworking implement mounted on the end of said first beam means opposite the end of said beam connected to said first turret, a second turret mounted for rotation on said chassis coaxially with said first turret, a second beam means having one end connected to said second turret and extending from said second turret and a second earthworking implement mounted on the end of said second beam means opposite the connection of said second beam to said second turret whereby either of said earthworking implements is usable as a counterweight to the other earthworking implements during operation of the other earthworking implement of the machine.
