Definitions

  • the present invention relates both to the field mixing mixers such as concrete mixers, and handling equipment or earthmoving equipment such as mechanical shovels and clamshells, and object a machine accessory that can be used in building work, public works or agricultural works.
  • An advantage of the above-mentioned mixing buckets is in their suitability for direct loading and in their mobility, which allows them be able to be filled with a mixing material, sand and gravel, to concrete by example, by a simple shoveling operation on the material heap, at a point of the site, then, after adding other components such as cement and water and while carrying out the kneading, to take the mixture to another point.
  • a disadvantage such devices lie in the fact that they tend to repel the heap of the material since the bucket is filled "by pushing" and they have a some difficulty exhausting the heap, for the same reason.
  • the main idea of the invention was to organize a bucket mixer, no longer the only bucket of an excavator, but at least one of the two buckets a clamshell bucket with two articulated jaws.
  • a device mixer and mixer for materials such as components for concrete, materials forages and the like, of the kind of device consisting of a capacity incorporating a kneading member, said capacity being supported by an articulated arm carried by a self-propelled machine, is characterized in its generality in that, the said capacity consisting of two substantially semi-cylindrical buckets of the bucket type clamshell in the form of jaws articulated along one of their edges, one of the buckets, said first, being supported by the said articulated arm, the other bucket, said second, being supported by the first, the buckets being further connected by opening and closing operating means, at least one of the buckets incorporates a kneading member advantageously supported by a shaft with means for driving in rotation of said shaft which are specific to it.
  • the loading of the device can be made in one operation by tightening the jaws on a pile of the material, or mixture of materials, to be kneaded, which avoids regrowth the pile with each loading, and which also allows a complete exhaustion of the heap.
  • the edge opposite to that of the articulation is conformed to the edge scraper, or has teeth-shaped organs intended to interpenetrate from one bucket to another for the dual purpose of ensuring the ability to close the capacity and allow scraping of the base of the pile of material.
  • each cup comprising a pair of substantially semi-circular flanges and each flange comprising a rolling support bearing for the shaft of the member of kneading
  • said bearing comprises a casing fixed removably shouldered on the outer face of the flange and extending inside the cup, said housing being consisting of a cylindrical part, a closure plate supporting the bearing bearing and a first seal closing the outer end of the housing, the inner end also comprising a braided seal, a conduit lubrication connecting the internal space of the housing to a lubricator intended to fill with grease the housing.
  • the fat puts the internal bodies of the housing and in particular the bearing, which is preferably a oscillating bearing, also known as spherical bearing, protected from the introduction of substances abrasive from kneaded materials.
  • the bearing which is preferably a oscillating bearing, also known as spherical bearing, protected from the introduction of substances abrasive from kneaded materials.
  • each support shaft of a kneading member is housed at its ends in a fret, or fur, of which it is made integral in rotation by screws such as CHC screws, which fur passes through the housing and the bearing and is in sealed friction with the seals sealing.
  • the exchange worn parts of the bearing can be carried out by simply releasing the housing, or even clearing of the freight, without having to extract the tree with its mixing member. This can be done quickly from the outside of the flanges by disengaging of the housing or separation of the fret from the tree it houses.
  • Means for emptying the buckets are advantageously constituted by a sliding hatch arranged on the bucket said first to neighborhood of the generator closest to the envelope of the kneading member, said hatch being maneuverable for closing, or conversely releasing, at least one orifice in the semi-cylindrical wall of said bucket. Note that this position of the hatch locates it approximately between the middle of the curved wall of the bucket and its toothed edge.
  • these emptying means comprise at least one orifice in the hatch located near its ends, and at least one orifice in the wall of the cup in the vicinity of the flange; the holes, respectively of the hatch and the bucket, can be alternately opposite by sliding of the hatch; an intermediate position of the hatch corresponding to obturation of the orifices; we must understand that the trap has a distributor function with three positions: emptying either on one side or the other and closed position intermediate.
  • the second bucket has a so-called manual filling opening near the hinge edge of the bucket, said opening being closed by law by a grid wide stitches.
  • This opening known to devices of the type, serves to add a mixing component, cement, water, etc.
  • a device of the invention also said bucket - clamshell mixer 1 is supported by an articulated arm 2 carried itself by a self-propelled machine 3.
  • the device 1 consists of two substantially buckets semi-cylindrical 6 and 8 articulated together around an axis 4 near an edge called articulation respectively of each of the buckets.
  • Each of the buckets to the invention a mixing or kneading member, symbolized by the respective dashed circles 11 and 12.
  • the invention has no interest in these kneading members which are diverse and known in themselves and which can be screw-shaped organs, pale organs, doctor blade organs, etc .; these organs have, however, the common characteristic of being rotatable about an axis respective parallel to the hinge axis of the buckets to each other.
  • Hydraulic means such as jacks 13 allow the operation of the arm 2, while a jack 14 controls the tilting buckets in the vertical plane.
  • the device 1 of the previous figure which constitutes the element to which the invention relates, is shown separate from the arm 2 to which it can be fixed by means of members such as crank pins 15 and 16 secured to the first bucket 6.
  • a jack 17 is intended to control the opening and closing buckets by pivoting the second bucket 8 about their common axis of articulation 18.
  • the sliding hatch 30 is provided in the vicinity of its ends with orifices 31, 32 which can be alternately placed opposite respective orifices 33, 34 formed in the wall of the first bucket 6, by sliding the hatch in the slides 31 under the control of the jack 29, these coincidences corresponding to emptying positions, or occupy a middle closed position such as shown in the figure.
  • the hatch openings may open into flexible pipes as known from the prior art.
  • driving means 36, 38 such as hydraulic motors, for rotating shafts kneading members, buckets 6 and 8 respectively.
  • teeth such as 9 are fixed on the edges 41, 42 of the cups, and it appears that these teeth interpenetrate in such a way that, even in the event of pronounced wear on their sides, the closure will always be substantially watertight, thanks to the permitted approximation of edges 40, 41; the dashes 43 along the edges of the teeth indicate the conformation in bevel of these edges.
  • the lateral tightness of the buckets is obtained by covering flanges, at least the allowed approximation of the edges, one of the buckets fitting slightly into each other.
  • a bearing 24 essentially comprises an oscillating bearing or a spherical bearing housed in an obviously a so-called bearing plate 52 closing the outer end of a cylindroconical housing 53; the bearing is supported from the outside against the bearing plate, which itself is also supported from the outside in the outer end of the housing 53, itself also shouldered and fixed in an opening in a flange, for example 26 well 6; it should be clearly understood that the two flanges of each of the cups comprises, facing one another for each bucket, such bearing arrangements.
  • a mixing member support shaft such as the shaft 54 is housed at each of its ends in a fret 56 formed of a metal hard; the shaft is made to rotate with the freight using two CHC 55 screws, the freight passes through the internal cage of the bearing 51 which supports it; joints, braided for example, such as 57 and 58 seal respectively the fret 56 and the closure plate 52 on the one hand and the conical end of the housing 53 on the other part, and thus isolate the internal space of the case.
  • This internal space divided by a succession of baffle discs such as 59, 59 ', coaxial with the freight and integral alternately (59) of the fret and (59 ') of the housing, is filled with grease by a conduit 60 and greaser 62.
  • a circlip 61 wedges the bearing in the bore of the plate bearing.
  • the second bucket has an opening called manual filling near the hinge edge of the bucket, said opening being legally closed by a grid 70 to wide stitches.
