Definitions

  • An excavat-or bucket adapted to be mounted on a tractor, is termed of a first bucket section secured to lifting arms on the tractor and a second bucket section movable relative to the first bucket sect-ion.
  • a pair of hydraulic jacks are positioned on the finst bucket section and have piston arms movable between an extended positi-on and a retracted position.
  • the first and second Abucket sections and the piston arms a-re interconnected by pivotally connected link members. When the piston arms are in the fully extended position, the second bucket position is in its closed .position relative to the first bucket section.
  • the second bucket section first moves outwardly away from the first bucket section in a rectilinear path and then pivots through a curvilinear path about its end section secured to the piston arm until it reaches its fully opened position with the piston .arm fully ,retracted into the jack cylinder.
  • the pivot c-onnection to the second bucket section of the link member extending between the first 4and second bucket sections is aligned with the axis of the piston arm permit-ting the bucket to be opened at an angle of 125 with the first bucket section.
  • the link members interconnecting the first and second bucket sections and the first bucket section and the piston arm are arranged in substantially parallel relationship. Due to the arr-angement ot the excavator bucket, it can be employed for a number of operations.
  • the jaw can perform these movements because of the special nature and des-ign of the linkages used to move the jaw.
  • a very impor-tant consideration in linkages of this kind which include three stationary pivots and two movable pivots, is the positioning of the hydrodynamic actuators which are adapted to open and close the jaw and which take Ithe form of hydraulic jacks, the term positioning referring to the position of the jacks when the bucket is in its fully lowered position and the jaw is in the closed state. Conventi-onally, the positioning or siting is such, depen-ding upon the linkage, used, that with the bucket and jaw in the conditions just specified the jack axes extend substantially parallel with the horizontal plane in which the excavating machine rests on the ground.
  • the invention is an improvement in or relating to buckets of excavating machines or the like, of the kind in which the jaw for opening and closing the bucket mouth is connected to the bucket via lateral linkages operated by hydraulic jacks.
  • the axes of the jacks which latter are parallel wi-th one another, are, with the bucket in its fully lowered position and with the jaw in the closed state, substantially perpendicular to the horizontal plane rin which the wheels or crawler treads ot the excavating machine comprising the 'bucket rest on -the ground; this feature in association with a linkage comprising three stationary rand two mobile pivots increases the range of work which the ⁇ bucket can perform.
  • FIGURE 1 yis a diagrammatic side elevation of the preferred embodiment of the present invention mounted -upon a self-propelled vehicle of which one land wheel is visible;
  • FIGURE 2 is a plan view of the bucket shown in FIGURE l;
  • FIGURE 3 is Va side elevation of a selfprope1led vehicle which has been equipped with a bucket :accor-ding to the invention
  • FIGURE 4 shows the bucket being used as -a combined skimmer and quasi-grab
  • FIGURES 5 and 6 rsho-w two stages of operation, the stages shown in FIGURES 4, 5 and 6 being consecutive;
  • FIGURE 7 shows the bucket being use-d as a metering device
  • FIGURE 8 shows the bucket being used as a grab bucket
  • FIGURE 9 shows the bucket Ibeing used as a bulldozer.
  • FIGURE shows the bucket being used as a skimmer bucket.
  • a tractor A having rubber-tyred land wheels 44 carries a bucket B on pivoted arms 10 disposed at each side of the tractor A.
  • a movable jaw C can be opened and closed relatively to a box or box part 12 of the bucket through the agency of a hydrodynamically operated system 18 of links disposed near a sidewall 14 of the box 12 and a similar system ⁇ 20 is disposed near a sidewall 16 of the box 12, the arrangement of the systems 18, 20 being symmetrical.
  • Each system comprises two links 22, 24 of which the link 22 is pivotally connected at 26 to the respective one of the sidewalls 14, 16 and of which the link 24 is pivotally connected at 28 to the respective one of said sidewalls.
  • the link 22 is pivotally connected at 30 to the respective sidewall of the jaw C, and the link 24 is pivotally connected at 32 to a tailpiece 34, one tailpiece being connected to each sidewall of said jaw C.
  • the links 22, 24 and the tailpiece 34 form three sides of a quadrilateral whose fourth side is the unvarying distance between the pivot axes 26, 28.
  • actuating means in the general form of hydraulic jacks D adapted lto be operated from the cab of the tractor A.
  • Each jack D is pivotally connected at one end thereof to the bucket B and at the other end thereof to a part of the respective one of the systems 18, 20.
  • a bottom lug 36 of cylinder 38 of each jack D is pivotally connected to the bottom corner of the box 12 and the free end of a rod 40 of each jack D is pivotally connected to the point 32 at which the link 24 is connected to the tailpiece 34.
  • the structure, size and design of the bucket B and, more particularly, of the systems 18, 20 of links thereof, all of which are described above, are such that, when the bucket is in the fully lowered position shown in FIG- URE l with the jaw C closing the mouth of the box 12, the longitudinal axes of the hydraulic jacks D extend substantially at right-angles to the surface 42 (which may or may not be truly horizontal) of the ground on which wheels 44 of the tractor A rest.
  • the jacks D are disposed -between the planes containing the exterior surfaces of the sidewalls of the box 12, and, therefore, do not project -beyond said sidewalls. If required, the jacks can be housed in seats or the like in the box 12.
  • Each system 1'8, 20 Ihas three stationary pivot axes 26, 28, 36 and two pivot axes 30, 32 which are displaceable.
  • the jacks D are operated to retract the rods 40 into their respective cylinders, the movable pivots 32 approaching the stationary pivot axes (see FIGURE 9).
  • the jacks D are operated so that the rods 40 -move axially and outwardly of the cylinders and move the Imovable pivot points 32 away from the stationary pivot axes 36.
  • the structure and size and design of the improved bucket and, more particularly, the arrangement of the jacks relatively to one another are such that the bucket B can perform a wide range of jobs whose main features are diagrammatically shown in FIGURES 4 to l0.
  • FIGURE 4 shows the bucket B in the tirst stage of working as a combined skimmer bucket and quasi-grab bucket. At this stage the jaw C is in the fully open position in which the rods 40 are in their fully retracted position.
  • the bucket B has been lmoved in the direction indicated by an arrow Y in FIGURE 4 and has skimmed a pile of earth 11.
  • FIGURE 5 shows the next stage, namely, that at which the jaw C, moving in the direction indicated by an arrow Z, has bitteninto the pile 11, the front edge of the 4 i jaw C having ⁇ moved in an arc until the desired point was reached.
  • the bucket B In the final stage, shown in FIGURE 6, the bucket B is in its closed condition with the bite of earth in the bucket.
  • the geometric and kinetic characteristics of the l systems 18, 20 are such that, during the movement yfrom i the position shown in FIGURE 5 to the position shown i in FIGURE 6 the front edge 13 of the jaw C has moved rectilinearly along the ground.
  • the total path of travel of the jaw C between the extreme positions thereof therefore has two components, and arcuate and a rectlilinear Y motion. Whilst the jaw C is accomplishing these movements, the box 12 stays in the position shown in FIG- URES 4 to 6.
  • FIGURE 7 shows the bucket B adapted to act as a dispensing or metering device, this being made possible by the fact that the spacing s between the front edge 13 of the jaw C and the leading edge of the box 12 can be adjusted very accurately and can be maintained by the systems 18, 20 of links.
  • FIGURE 8 shows the bucket Bbeing used as a grab bucket.
  • the paths travelled by the front edge 13 of the jaw C and the leading edge ofthe box 12 are shown by ⁇ the chain line.
  • FIGURE 9 shows, as has been stated above, the bucket B in the fully open condition thereof, this being the condition which must be maintained when the bucket is to be used as a bulldozer.
  • FIGURE l0 shows the bucket arranged to act as a skimmer.
  • the bucket Bis kept in its closed condition but,
  • FIGURE 3 includes an illustration of the bucket B which has been raised by the ⁇ lever 10 and also tilted to dump the load.
  • the mounting of the jacksD in the manner described above with particular reference to FIGURE 2 has the i result that the jacks offer noresistance to the working movements of the bucket and also that the jacks are protected against damage and breakage.
  • An excavator bucket adapted to be mounted on a tractor and comprising a irst bucket section adapted to be secured to lifting arms on the tractor, a second bucket section movable relative to said first bucket section between a fully opened position and a fully closed position, said second bucket section comprising a floor member and two triangularly shaped spaced side members secured along one edge thereof to said lioor member and the other two edges thereof extending from the oor member in converging relationship and meeting at an apex point remote from said floor member, a tail piece-secured to said second bucket section and extending from said apex point away from said oor member, a pair of hydraulic jacks pivotally mounted on said first bucket section and each having a piston arm movable between an extended position and a retracted position, said piston arm connected at its outer end to the end of said tail piece remote from the apex point of said second bucket section, whereby said piston arm is in its extended position when said second bucket section is in its fully closed position relative
