Definitions

  • the present invention concerns a tooth for buckets of excavators or suchlike, consisting of a work element with a pointed shape, also called point, and a relative support element, or point-bearer, associated with each other by pin means.
  • Buckets for excavators of a known type substantially comprise an open box-like body, constrained to the mechanical arm of the excavator, on one side of which a plurality of teeth are mounted.
  • Each tooth consists of two components: a support element, or point-bearer, attached to the side of the box-like body of the bucket, and a work element, or point, associated with said point-bearer due to their coupling shape and constrained thereto by means of a pin element.
  • the point-bearer has a wedge-shaped protrusion able to be inserted in a cavity of a mating shape made in the rear part of the point; the pin element is arranged transverse, and substantially through, in a seating made on said wedge-shaped protrusion and on the walls of the cavity of the point.
  • This type of tooth allows the point to be interchangeable, when it has become worn due to the knocks and high loads to which it is subject when the bucket is used.
  • the pin element which is substantially put in direct contact with the point, is subject to considerable forces which are then transferred to the point-bearer, precisely in correspondence with the wedge-shaped protrusion, that is, in correspondence with the part where its section is weakened due to the presence of the insertion seating of the pin element.
  • This situation can therefore entail, even frequently, the need to completely replace the teeth of the bucket, with long periods of inactivity of the excavators and an increase in the management and maintenance costs of the excavators.
  • One purpose of the present invention is to achieve a tooth for buckets of excavators, or similar equipment, wherein the stresses to which the point is subjected are discharged in a zone of high resistance of the point-bearer, so as to reduce the wear, the damage and the breakages done to the point-bearer and the pin element.
  • Another purpose of the invention is to achieve a tooth which allows a precise coupling of the point and the point-bearer, in any case facilitating the operations to assemble and dismantle the point in order to replace it.
  • the Applicant has devised and embodied the present invention to overcome the shortcomings of the state of the art in order to achieve the aforesaid purposes and to obtain other advantages.
  • the tooth according to the invention comprises, like the teeth for buckets of a known type, a work element, or point, and a relative support element, or point-bearer; the support element consists in a single piece of a main body and a front protrusion able to be inserted in a mating cavity made at the rear of the work element, so as to define a coupling condition of the work element itself and the support element, in which the latter are able to be reciprocally clamped by inserting pin means into a relative housing seating.
  • the work element comprises at least a fin, or appendix, protruding from the rear with respect to the relative cavity, able to couple with the main body of the support element; the housing seating for the pin means is made partly on the appendix and partly in the main body.
  • the work element comprises two fins, parallel to each other and symmetrical with respect to a median longitudinal axis of the work element, defined by an extension of the lateral walls of the cavity.
  • Said fins are substantially shaped like a prism with a trapezoid base and are able to be arranged in mating recesses of the main body defining a relative upper edge.
  • the tooth according to the invention normally has a first slit between the upper profile of the fins and the upper edge of the mating recesses.
  • the housing seating of the pin means is defined by a through hole, made on the main body, and by two apertures, each one made on a relative fin, able to be put in cooperation with said through hole.
  • the apertures of the fins are slightly off-center, towards the front protrusion, with respect to the through hole, so that the insertion of the pin means into said housing seating determines the alignment of said apertures and the through hole and a further penetration of the front protrusion into the mating cavity.
  • said pin means are axially hollow and have a longitudinal through cut able to allow a partial elastic deformation of their section.
  • the front protrusion of the work element has a substantially polygonal transverse section, for example square, hexagonal or suchlike, which progressively reduces from its rear end, that is, facing towards the main body, to the front end.
  • said front protrusion has at least a longitudinal groove on one face.
  • FIG. 1 shows a bucket provided with teeth according to the invention
  • FIG. 2 is a three-dimensional view of a tooth for buckets according to the invention.
  • FIG. 3 is a lateral view of the tooth in FIG. 2 ;
  • FIG. 4 is an exploded view of the tooth in FIG. 2 ;
  • FIG. 5 is a lateral view, partly in section, of a tooth for buckets according to the invention in a variant embodiment
  • FIG. 6 is a section from A to A of FIG. 5 ;
  • FIG. 7 is a section from B to B of FIG. 5 ;
  • FIG. 8 is a section from C to C of FIG. 3 ;
  • FIG. 9 shows a variant of FIG. 3 .
  • the reference number 10 denotes the tooth according to the invention for buckets 11 of excavators or similar equipment.
  • Said tooth 10 comprises a point-bearer 12 , able to be attached in a known manner to the lower side 11 a of the bucket 11 , and a point 13 able to be associated due to their coupling shape at the front of the point-bearer 12 and able to be clamped on the latter by means of a pin 17 .
  • the point-bearer 12 defines in a single piece a main body 14 , at the rear, able to be positioned above the lower side 11 a of the bucket 11 , and a front protrusion 15 , wedge-shaped, able to be inserted in a cavity 16 , of mating shape, made on the rear of the point 13 , interfering with the inner surface of the cavity 16 .
  • the front protrusion 15 has a substantially hexagonal transverse section, with two lateral grooves 23 .
  • the front protrusion 15 has a substantially square transverse section, with two grooves 23 respectively on the upper and lower face.
  • the pin 17 is advantageously axially hollow and has a longitudinal cut 17 a which allows a partial elastic deformation of the section.
  • the lateral walls 18 of said cavity 16 extend beyond the latter, defining two protruding fins, or appendixes, 19 ; said fins 19 , in the condition wherein the front protrusion 15 is inserted in said cavity 16 , are able to house in corresponding recesses 22 of the main body 14 , so as to overlap with the latter.
  • the fins 19 substantially configured as a prism with a trapezoid base, have at the upper part respective hollows 19 a of a width substantially equivalent to the diameter of the pin 17 ; said hollows 19 a are able to align with a through hole 21 , made transversely in correspondence with the recesses 22 of the main body 14 , and of a diameter substantially equivalent to that of the pin 17 , in order to define therewith a housing seating 20 for the pin 17 .
  • the insertion of the pin 17 in said housing seating 20 determines the constraint of the point 13 and the point-bearer 12 , preventing the separation thereof.
  • the hollows 19 a have the relative axis slightly off-center, towards the front protrusion 15 , with respect to the axis of the hole 21 ; for this reason, the insertion of the pin 17 into the seating 20 draws the point 13 on the point-bearer 12 , determining a further penetration of the front protrusion 15 into the cavity 16 and hence an increase in interference between the two, making the clamping of the point-bearer 12 and point 13 more stable and secure.
  • first slit 24 of a width in the range of some tenths of a millimeter
  • second slit 26 of a slightly greater width
  • the fins 19 instead of the hollows 19 a the fins 19 have respective through eyelets 19 b , which have the same function; said through eyelets 19 b are arranged substantially vertical and are able to align with a hole 21 made in a more central position on the main body 14 of the point-bearer 12 .
  • the load “P”, weighing on the front part of the point 13 determines a moment which tends to make the point 13 rotate with respect to the point-bearer 12 , in the direction of the arrow indicated by the letter “R” ( FIGS. 3 and 5 ), taking the upper profile 19 c of the fins 19 to abut on the upper edge 22 a of the recesses 22 , so as to discharge at least a part of the stresses deriving from the load “P” on the main body 14 .
  • the lower edge 19 d of the hollow 19 a approaches the pin 17 , but without coming into contact with it, so that the same pin 17 is not substantially affected by the shearing forces deriving from the load “P”, thus considerably reducing the risks of breakages.
  • the tooth 10 according to the invention therefore allows a better distribution on the point-bearer 12 of the stresses deriving from the load “P” weighing on the point 13 , limiting the forces affecting the pin 17 .
  • the front protrusion 15 could have a rhomboid or pentagonal section, or otherwise.
  • the pin 17 could be of a different type with respect to the one shown here.
