Definitions

  • This invention relates generally to trenchers or backhoes and is directed more particularly to a new and improved telescopic dipperstick construction for use therewith.
  • Telescopic dipperstick constructions are shown in the prior art in my US. Pat. No. 3,140,000 issued July 7, 1964.
  • two hydraulic cylinders are provided, one for rotating the bucket and the other for moving the telescopic dipperstick member longitudinally with respect to the outer or first dipperstick member.
  • the hydraulic cylinders in the above mentioned patent are mounted such that the cylinder for operating the bucket is positioned directly over and above the cylinder for moving the telescopic member.
  • the cylinder for moving the telescopic member is placed in side of the telescopic member.
  • Another object of the invention is to provide a new and improved telescopic dipperstick wherein the hydraulic means for positioning the telescopic or bucket support portion of the dipperstick as well as the hydraulic means for rotating the bucket are both externally mounted.
  • a further object of this invention is to provide a new and improved dipperstick construction wherein both of said hydraulic means are positioned externally and preferably parallel to each other'when viewed from the top.
  • Another object of the invention is to provide a new and improved telescopic dipperstick construction which allows a mechanic to easily'service the hydraulic cylinders and which because the cylinders are side by side makes for a less bulky construction.
  • FIG. 1 is a side view of a tractor mounted apparatus including a dipperstick embodying the invention
  • FIG. 2 is an enlarged side view of the dipperstick shown in FIG. 1;
  • FIG. 3 is a top plan view of the dipperstick shown in FIG. 2;
  • FIG. 4 is a section taken along the line 4-4 of FIG. 2;
  • FIG. 5 is a side view of another embodiment of a dipperstick embodying the invention.
  • FIG. 6 is a top plan view of the apparatus shown in F IG. 5;
  • FIG. 7 is a sectional view taken along line 7-7 of FIG. 5;
  • FIG. 8 is a side view of another embodiment of a dipperstick embodying the invention.
  • FIG. 9 is a partial top plan view of the apparatus shown in FIG. 8;
  • FIG. 10 is a perspective of the supporting member of the apparatus shown in FIG. 8.
  • FIG. 11 is a section on the line 11-11 of FIG. 8.
  • the invention relates particularly to an apparatus adaptable for use with a machine such as a trencher or backhoe which includes a boom and a bucket supported by a dipperstick.
  • a machine such as a trencher or backhoe which includes a boom and a bucket supported by a dipperstick.
  • the trencher or backhoe is shown mounted on a tractor, the hydraulic system of which provides hydraulic power for the boom, bucket and dipperstick.
  • the tractor shown is of the track type and includes an engine 10, tracks 11, seat 12 and a boom 13.
  • the boom 13 is pivotally connected at 14 to a support 15 which in turn is pivotally connected at 16 to a support 17, which is detachably connected to the tractor.
  • the boom 13 is adapted to be raised and lowered by a hydraulic cylinder 21 connected adjacent its opposite ends at 22 and 23 to boom 13 and support 15 respectively.
  • the dipperstick 19 in this embodiment is shown in FIGS. 1 through 4 of the drawings. It comprises a support member 20 pivotally connected at 20A to the boom 13. At 26 there is shown a hydraulic cylinder having a ram 27, the cylinder being coupled at one end to the boom 13 at 28 and the ram being coupled at 208 to the support member 20. The hydraulic cylinder 26 is provided for rotating the telescopic dipperstick 19 about the pivot point 20A.
  • the support member 20 includes a plurality of members shown in FIG. 4 at 30, 31, 32 and 33 constructed to provide a guide means or guide passage having a wear plate shown at 34 provided therein. Within the guide passage there is positioned for slidable movement therein a telescopic member shown at 35. At one end of the telescopic member 35 there is supported a bucket 38 which is pivotally connected at 39 to the telescopic member 35.
  • Pivotally mounted linkage means generally shown at 40 is provided and includes both bucket pivot links 41A and 41B and bucket extension links 42A and 428.
  • Links 41A and 41B are pivotally connected to the telescopic member 35 and links 42A and 42B are pivotally connected to the bucket.
  • the links 41A, 41B, 42A and 42B are pivotally connected together and to a ram 44 of the bucket control cylinder 45.
  • the bucket control cylinder is itself pivotally coupled at one end thereof by a hitch 46 to the telescopic member 35.
  • the ram 44 as well as the cylinder 45 are positioned off center of the centerline of the telescopic member 35 when viewed from the top in FIG. 3 and accordingly the links 41A, 41B, 42A and 42B are constructed such that they are connected to the ram 44 off center from the center line of the telescopic member 35.
  • a hydraulic cylinder 49 which at one end thereof is pivotally coupled at 50 to the member 20.
  • the ram 51 of the hydraulic cylinder is pivotally connected at 52 to the telescopic member 35.
  • the bucket control cylinder 45 as well as the cylinder 49 are positioned externally of the telescopic member 35 are mounted in a side by side, parallel relationship when viewed from the top. In this way they are easily, readily accessible for servicing and in addition the telescopic member protects them from damage in use since they are on the opposite side of the telescopic member from thebucket.
  • FIGS. 5 through 7 wherein another embodiment of the invention is shown, in this embodiment the bucket rotating hydraulic cylinder is shown at 60 and is mounted by use of a welded cylinder hitch 61 to the telescopic member 35.
  • the telescopic member 35 does not move any further to the right than the position in which it is shown in FIG. 6. If the design of a machine is such that a long bucket rotating cylinder is satisfactory it can be constructed as shown in FIGS. 1 through 4 whereas if a shorter bucket rotating cylinder is necessary, the construction shown in FIGS. 5 through 7 would be preferable.
  • FIGS. 8 through 10 wherein a third embodiment is shown, in this embodiment the support member 20C is extended forwardly towards the bucket from the pivot point 20A thereby adding support for the telescopic member closer to the bucket.
  • the cylinder hitch 80 is welded to the top wall of the telescopic member and it slides longitudinally of the slot 31A provided in the top wall 31 of the support memberwhen the telescopic member 35 is moved longitudinally. relative to the support memberby the ram 51.
  • bearing plates 90 are
  • bearing plates 92, 93 are provided adjacent to the other end. If desired these bearing plates may telescoping member-35rather than to the walls 31 and 33 of i the support member20C.
  • FIGS. 1 through 10 The side by side location of the cylinders both outside of the support and the telescopic member as shown in FIGS. 1 through 10 is a less bulky arrangement of parts than the prior art constructions which showonecylinder positioned in the telescopic'member and the other above itwWith this invention both cylinders are exposed foreasy service and repair.
  • the operation of the device will be apparent to persons skilled in the art from the foregoing description.
  • a telescopic dipperstick assembly for mounting on a boom or the like, comprising in combination a supporting member suitable for attachment tothe boom, said supporting member having a guide passage formed therein, a telescopic member slidably supported in said guide passage, a bucket pivotally connected to be attached to the 4 i the telescopic member at one end thereof, linkage means connected to said bucket and; said telescopic member, a first hydraulicv means coupled at one end to said supporting member and at the other end to said telescopic member, a a second hydraulic means coupled atjone end to said telescopic member and at the other end to..said linkage means, said first t and secondhydraulic means being positioned above said supthe top.
