Definitions

  • ABSTRACT A dred er-loader vehicle havin a shovel loader g 8 37/1 17.5 at the front and a dredging outrigger in the rear.
  • the dredger Int. Cl E021 3/28 swingably mounted on the rear portion and including a counlFieldl of Search ..214/132138; terweight, all above the rear axle.
  • the motor is located above 37/103, 117.5 the front axle.
  • This invention relates to a dredger-loader consisting of an at least two-axle vehicle, an earth-moving device such as a loading shovel or grading device articulated on the front of the vehicle, and a dredger swingably positioned on the rear of the vehicle.
  • ditchers can be attached on the tail end of conventional front loaders.
  • the drive motor including the driving gears, distributor gears, and hydraulic pumps are customarily arranged in a manner protruding backward, above the rear axle which is arranged like a pendulum.
  • the additional attachment of a ditcher there occurs a very unfavorable weight distributionaln order to prevent the vehicle from tipping over during the transportation of the excavator, it is therefore absolutely necessary to lock the jointed swinging axle.
  • a further disadvantage in such equipment which is made for multipurpose use, consists in the fact that the accessory dredger has a swing radius limited only to about 180" and that no counterweight is available in case of excavating work that runs lateral with respect to the direction of movement or driving. Therefore, the scraping forces may then be employed only to a limited extent.
  • tractors which are converted from farm tractors and which are equipped with a loading scoop that is arranged swingably over the front axle and on whose tail end ditchers can be attached.
  • a loading scoop that is arranged swingably over the front axle and on whose tail end ditchers can be attached.
  • poorer loading and grading properties are obtained than in a vehicle specially designed for this purpose because of the fact that the loading scoop or shovel is arranged above the forward control or guidance jointed swinging axle.
  • these carrier vehicles in themselves, are built in the form of traction vehicles, there is usually only provided a single-axle drive with oversized rear driving wheels and small front wheels. This gives poor ground pressure distribution.
  • the invention is based on the task of further developing a dredging loader avoiding the described disadvantages, to such an extent that optimum conditions will be available in regard to the bracing and absorption of working forces and weight distribution both for the use of the*loading shovel and for the use of the ditcher. Also, obtaining the swingability, as well as force utilization which will remain fully equal over the entire swing range, will become possible particularly when using the dredger or excavator tool. This is intended simultaneously to achieve considerable simplification of the function requiring the operator to change seats from one position toanother or to eliminate this seat-changing altogether.
  • the vehicle motor including the gears and the hydraulic equipment, be arranged above the front axle and that the frame of the excavator, provided with a counterweight, be arranged approximately above the rear axle.
  • the operating positions for the excavator and the front loader are arranged on a baseplate attached to the vehicle above the rotatable excavator frame or chassis. This gives an excavatorloader with full utilization possibility both for the loading shovel and for the ditcher, without any need for possibly be hampered in this fashion.
  • a practical further development of the invention consists in arranging the motor on the front of the vehicle and the excavator, with a turntable, on the rear of a vehicle designed in the form of an articulated chassis in which the perpendicular turning axis lies in the middle between the front and the rear axle.
  • articulated chassis vehicles this gives the advantage of a smaller turning circle for the vehicle and good maneuverability in a very small space.
  • the driver's positions can be arranged on a baseplate connected with the vehicle, the baseplate covering the rotatable chassis of the excavator and which rests on a central supporting bearing.
  • This proposal likewise offers the possibility of combining the driver's position and the excavator operating position so that the forward-facing control panel or dashboard for the operation of the excavator can be operated from a swing-seat which can be rotated by I.
  • the excavator control panel can be swung along, above the baseplate, together with the seat and with the excavator chassis.
  • FIG. 1 shows a cross section of an excavator-loader according to the invention, designed as an articulated-chassis vehicle.
  • FIG. 2 shows a top view of the same piece of equipment.
  • FIG. 3 is another version, in the same illustration as in FIG. ll.
  • the vehicle which is designed as an articulated-chassis vehicle in the example according to FIGS. 1 and 2, consists of a forward vehicle portion 2 and a rearward position 3 which are flexible and controllably connected with each other via a bending axis 6 which is arranged exactly in the middle between the front axle t and the rear axle 5.
  • the forward position includes the drive motor with the driving gears, distributor gears, and hydraulic pumps for various working tools provided on the vehicle.
  • the front axle 4i is constructed in the form of the noncontrollable rigid axle, while the likewise powered and noncontrollable rear driving axle 5 is positioned, in pendulum fashion on rear position 3, in a universal joint bearing 7, schematically indicated at point 7
  • a loading shovel, schematically indicated at d, is attached to the front portion 2 in a manner customary in front loaders.
  • This front loader has good grading and loading properties by virtue of rigid axle 4 and weight stressing due to the motor and the gears, as well as the fuel and hydraulic fluid tanks located on the front portion.
  • a turntable mount lb which supports an excavator chassis 11, with a counterweight 12, which can be swung about 250 (see FIG. 2).
  • the limitation of the excavator swing arc X to 250 is explained by the design in accordance with the invention. More specifically, the arc is limited by the fact that the rotatable excavator chassis 11 is covered by a fixed baseplate 14 on which the driver's location 15 and the excavator-operating location 16 are combined.
  • a perpendicular attachment 17 to chassis 9 on rear portion 3 for the purpose of supporting the baseplate thus limits the excavator swing range.
  • baseplate 14 has a borehole at the pivot of the excavator; a bushing 18 for the excavator hydraulics protrudes upward through this borehole, and the bushing 18 is surrounded by a supporting bearing 13 for baseplate 14.
  • a rotatable and lockable seat 19 and the excavator operating panel 16 are attached to baseplate 14 so that an outrigger 20, with a bucket arm 21 and a bucket 22, attached to excavator chassis l 1, can be properly observed from there.
  • the seat 19 which is flexibly attached at 23, can be rotated by 180 so that it will assume the position indicated with the broken lines in FIG. 1, pointing toward driving wheel 24 and driver's dashboard 15.
  • the driver's and operating positions l5, 16 as shown in FIG. 1, it is basically possible to have the kind of arrangement in which the seat and the excavator operating panel can be swung along with chassis 11.
  • control lines from the control panel run to the excavator through the hollow supporting column and not, as was customary in excavators with attachment devices in the past, from the control panel above the swing axle to the individual hydraulic cylinders on the outrigger, the bucket arm, etc.
  • the motor is positioned in a vehicle with a unitary chassis 25over the front axle and chassis 11.
  • the vehicle includes a noncontrollable, rigid front axle and a rear steering axle.
  • the excavator is positioned above the rear vehicle wheels, in such a way that it can be rotated around a perpendicular swing axis.
  • the excavator swing axis is here shifted somewhat further to the rear from the place above the rear axle, so that-considering the protruding counterweight l2--there will still be room for a broader, longer attachment or supporting part 26 which, via a baseplate 27 permits the stable positioning of the swing axis, so to speak, in a fork with bearing cups 28, 29.
  • the excavator chassis which is here likewise partly covered by baseplate 27, is included in the structure of the vehicle and there is achieved the same advantages as described before.
  • both operating positions, and this seat can be lockably swung around axis 23.
  • the operating position will then follow the actual excavator swing angle, for instance, from the indicated zero position, but nevertheless, provides excellent visibility.
  • the supporting legs 30 are then retracted from the zero position and'the seat is swung around the drivers position.
  • a dredger-loader comprising:
  • an excavator chassis rotatably mounted on said vehicle, said excavator being mounted on said chassis, said chassis having a counterweight to compensate for the weight of said excavator;
  • a dredger-loader as defined in claim 1 including a turntable on said rear portion, said excavator connected to said turntable, said turntable being rotatable in a horizontal plane.
  • a dredger-loader as defined in claim 4 including a front axle on said front portion and a rear axle on said rear portion, said axis being located midway between said axles.
  • a dredger-loader as defined in claim 1 including a non-- controllable rigid front axle attached to said front portion and a rear steering axle connected to said rear portion.
  • a. including a seat mounted on said baseplate;
  • a dredger-loader as defined in claim 8 including a supporting bearing between said chassis and said baseplates 10.
