Definitions

  • the present invention relates to a bucket wheel loader. For picking up piled up bulk goods from storage places. Frequently bucket wheel loaders are employed which are movable on caterpillar tracks which are designed similar to bucket wheel dredges employed in strip mining.
  • a boom carrying a bucket wheel is tiltable upwardly and downwardly and is journalled preferably on a C-shaped upper structure which rests on a track-laying carriage by means of a turntable which is rotatable about a vertical axis.
  • a boom provided with a discharging conveyor is connected to the upper structure and is laterally turnable independently of said upper structure.
  • FIG. l diagrammatically illustrates a side view of a bucket wheel loader according to the invention.
  • FIG. 2 is a top view of FIG. l.
  • the bucket wheel loader is characterized primarily in that the bucket wheel supporting member is without being laterally turnable mounted on the track laying carriage by means of a supporting structure in such a way that the plane passing through the center of said supporting structure and through the center of the bucket wheel will be located at an angle with regard to the -driving direction of said carriage while that end of the bucket wheel supporting member which with regard to the supporting structure is located opposite the bucket wheel, supports a bridge member which in a manner known per se establishes the connection of the loader with a storage place conveyor means.
  • the bucket wheel loader shown therein comprises an understructure or carriage 2 movable on two caterpillar tracks 1, 1a.
  • the two tracks may, in a manner well known in connection with track laying vehicles, individually be driven at ditierent speeds for permitting a steering of the carriage and for that purpose may also be driven in a direction opposite to each other.
  • the loader furthermore comprises a bucket wheel 3 which is supported by a rocker 4 resting upon understructure 2 by means of two rocking bearings 5.
  • the horizontal axis 6 (FIG. 2) of said bearings 5 forms an acute angle with the vertical central plane 7 of the understructure 2.
  • axis 6 may form an angle of 30 with the vertical projection of plane 7.
  • the said angle is not limited to 30 but may vary within the range of from to 45.
  • the arrangement is such that the vertical projection 8 of the vertical plane defined on one hand by center point 9 of bucket wheel 3 and on the other hand by the point 10 of intersection of axis 6 and vertical projection 7 of the vertical central plane of understructure 2 lforms an acute angle with the driving direction of the loader.
  • line 8 forms with line 7 an angle of 50, but the angle may also vary within the range of from 35 to 65.
  • bucket wheel 3 forms an acute angle with line 8 so that the axis of rotation 11 of the bucket wheel for instance forms an angle of 10 with line 8.
  • the vertical projection of the vertical central plane 12 of the bucket wheel forms with line 7, i.e. with the driving direction of the carriage 2, an angle of approximately Bucket wheel 3 is thus so arranged that when considering FIG. l, the bucket wheel is located in the direct vicinity of the caterpillar track 1, and when considering FIG. 2, is located adjacent the front -deviating wheel of said caterpillar track 1.
  • the rocker is provided with a crank while that arm 13 of the crank which carries the bucket wheel supports a transmission 14, and the bucket wheel driving motor 15 is arranged in a portion 16 located above the respective caterpillar track and pertaining to rocker 4.
  • a conveyor belt 17 is provided at the rear side of bucket wheel 3.
  • Conveyor belt 17 carries the material picked up by the bucket wheel and conveys said material along a straight line beyond point 10 to the rear end of rocker 4.
  • a conveyor belt bridge Suspended on said rear end in the manner of a universal joint at a point 18 is a conveyor belt bridge which is composed of two parts 19 and 20 longitudinally movable relative to each other. These displaceable parts may be of a design as it is described in U.S. patent application Ser. No. 447,128 filed Apr. 12, 1965, now abandoned.
  • the bridge member 20 rests on two joints 21 and through the intervention of a turntable 22 rests on a gateshaped carriage 23 which is movable on two rails 24 on both sides of conveyor belt means 25.
  • Conveyor belt 26 is within the conveyor belt bridge 19, 20 guided along a loop in such a way that it can adapt itself to an extension and reduction in the total length of bridge 19, 20.
  • the loader When picking up bulk material from a storage place, the loader according to the present invention moves along the bank to be picked up while the bucket wheel in bank operation picks up the material from the pile. It is of advantage that due to the arrangement of the bucket wheel as described above with regard to the carriage, the disstance 26 between the outermost point of the bucket wheel engagement with the bulk goods, and the vertical longitudinal plane 7 of the driving carriage is only relatively small. Since the resistance oliered to the movement ot the carriage by the engagement of the bucket wheel with the pourable goods acts upon carriage 2 or tracks 1, 1a with a relatively short lever arm, a relatively short spacing between the two caterpillar tracks 1, 1a will sufce.
  • the understructure can be considerablyA smaller dimensioned than is the case with heretofore known customary bucket Wheel loaders.
  • a relatively light and inexpensive device is obtained which is furthermore characterized in that it can be steered very easily, Such a device can easily adapt itself to the dierent slopes of bulk goods on the storage place.
  • the dot-dash lines in FIG. 2 indicate how the device will work for instance on a slope 27 which forms an acute angle with the storage conveyor 25.
  • Bridge 1S, 19 can adapt itself to the varying distances between the device and the discharge carriage 23.
  • Bucket wheel 3 can be lifted upwardly by means of rocker 4.
  • the rear lrocker portion is for instance equipped with a hydraulic hoist 28.
  • the dot-dash lines indicate the position of the rear end of rocker 4 and of the bridge member 19 which rests thereon. These parts are illustrated in a position according to which the bucket wheel is lifted into the position illustrated in dot-dash lines.
  • an operators cab 29 is arranged on the lower structure 2 behind rocker 4 on the same side as the bucket wheel 3.
  • a bucket wheel loader which includes: a yfreely movable carriage, a rotatable bucket wheel, longitudinally extending supporting means supported by said carriage and rotatably supporting said bucket wheel at one end portion of said supporting means, mounting means for preventing rotation of said supporting means about a vertical axis While permitting rotation of said supporting means about a horizontal axis, said bucket wheel being so located with regard to said carriage that the vertical plane passing through the center of said carriage and through the center of said bucket wheel forms an acute angle with the advancing direction of said carriage, bridge means having one end thereof supported by the other end portion of said supporting means, additional supporting means supporting the other end portion of said bridge means for pivotal movement about a substantially horizontal axis, and conveyor means leading from said bucket Wheel to said other end portion of said bridge means.
  • a loader in which said first mentioned supporting means forms a two-arm rocker pivotable in a vertical plane only which ⁇ forms an acute angle with the advancing direction of said carriage, one of said arms supporting said bucket wheel and the other one of said arms supporting said one end portion of said bridge means.
  • a bucket Wheel loader according to claim 2, in which said other arm of said rocker support said one end portion of said bridge means by a universal joint.
  • said trst mentioned supporting means comprises' a cranked portion rotatably supporting said bucket Wheel and otset with regard to the longitudinal axis of said rst mentioned supporting means in the advancing direction of said carriage.
