Definitions

  • the object of the present invention relates to a bucket of the type used in civil engineering machinery, such as excavators and backhoes, comprising means for crushing stone and similar materials.
  • Self-propelled vehicles equipped with buckets or scoops for collecting material such as stone or the like, inside which there are arranged crushing means for crushing the collected material to the desired size, are known in the technical field of the invention.
  • a known example of crushing means comprises two jaws, one of which moves in a pivoting manner with respect to the other and both jaws move such that they compress the material between them, crushing it.
  • these crushing means lead to some drawbacks which cause a poor performance in the processing of the crushed material.
  • document EP1138834 describes a crusher bucket which, unlike the preceding document, does indeed describe a complete rotational movement of the jaws. Nevertheless, this document does not describe a forward movement which allows gradually taking stones or similar material into the bucket.
  • document ES2258161T3 describes a scoop or bucket for crushing and sieving stone which is a combination of the two documents described, as it indeed describes a complete rotational movement and a forward movement.
  • this solution optimizes effective and efficient crushing of the stone, it presents drawbacks in the intake of the material into the scoop.
  • the translational and rotational movement prevents an efficient intake of the material, which considerably reduces the crushing capacity.
  • this elliptical (translational and rotational) movement means that the same pressure is not exerted on the entire jaw given that at the ends of the axis of the imaginary ellipse, when the moving jaw is raised, the pressure is lower than in the movement parallel to the flow direction where crushing actually takes place.
  • the lack of uniform pressure implies a lower performance, and therefore a lower crushing capacity.
  • the performance of the buckets or scoops described in the state of the art is affected by problems that must be solved concerning the product blocking up the inlet of the bucket mouth.
  • document EP3073019 describes a moving jaw incorporating the bucket that performs an essentially circular movement.
  • This circular movement allows, at the same time, the compression of the material (stone) housed therein and the introduction of said material inwards simultaneously.
  • the pressure and forward movement of the moving jaw is completely homogeneous on the entire contact surface of the moving jaw, increasing its crushing capacity.
  • the bucket incorporates an inclined plate at an inlet integral with the moving jaw and having a certain angle of inclination such that, due to said angle and movement of the moving jaw, it prevents the material from blocking the inlet and directs it towards the jaws of the bucket.
  • An objective of the present invention relates to a crusher bucket for crushing stones and the like with an optimized performance which is achieved by obtaining stone crushing that increases the crushing capacity of the bucket. This objective is achieved with the elements described in the independent claim. Other particular embodiments are described in the dependent claims.
  • the crusher bucket for crushing stones and the like object of the present invention comprises a scoop-shaped body defining an inlet for the stone to be crushed and an outlet for the crushed stone, between which there is defined a stone flow direction; means for crushing the stone, the crushing means comprising a first moving jaw and a second fixed jaw which are housed in the scoop-shaped body and arranged facing one another, such that a lower surface of the moving jaw is facing an upper surface of the fixed jaw; and activating means for activating the first moving jaw with respect to the second fixed jaw, characterized in that the mentioned movement means consist of a motor which drives an eccentric shaft through a transmission element; and wherein said eccentric shaft is integral with the moving jaw through a moving side support which is configured as a side plate parallel to the side guards in a transverse position with respect to the inlet and outlet of material; and wherein said moving side support comprises two ends, one of them being integral with the eccentric shaft, whereas the opposite end has an inverted C-shaped opening housing at least one bolt configured for limiting the rotational movement exerted
  • FIG. 1 shows a schematic view of the crusher bucket object of the present invention.
  • the following reference numbers are used in said Figure 1 :
  • the bucket or scoop formed according to the present invention is indicated by means of reference 1.
  • the bucket 1 is arranged so that it can be connected to an arm of an excavator- or backhoe-type machine for public works not shown in the attached drawings. To that end, it has a fastener for fastening to the arm of the machine of the type known, for example, in documents ES2304330 , ES2192478 , or ES1017841U , or equivalent systems.
  • the bucket 1 comprises an external structure similar to buckets described in the state of the art, particularly the one described in document EP3073019 , and comprising a scoop-shaped body which has a modular configuration.
  • the inlet 3 of the bucket 1 is therefore attached to the side guards 2 of the jaws 5 and 6 by means of any attachment elements which allow replacing the blade or the side guards 2 themselves in the event of wear, a rather common occurrence in this type of machinery.
  • the inlet 3 is configured as an opening for loading broken stone, gravel, stones, and the like and has a cross-section that is larger in comparison with an opposite outlet 4 for unloading the crushed material after the crushing process carried out inside the body of the bucket 1.
  • the elements which allow crushing the stone at the inlet are the mentioned jaws 5 and 6. These jaws are configured as a moving jaw 5 located on a fixed jaw 6. Both jaws 5 and 6 are accessible and removable in the event of wear thereof. Furthermore, conventionally, the contact surfaces of the jaws 5 and 6, i.e., the surfaces facing one another, are provided with longitudinal grooves extending parallel to the flow direction of the introduced stone and suitable for facilitating the crushing thereof.
  • the grooves define a plurality of ribs and recesses, alternating successively such that a rib of the moving jaw 5 corresponds with a recess of the fixed jaw 6, such that the crushing of the material is stronger during the movement of the first jaw 5. Furthermore, given that the ribs of one jaw can penetrate the recesses of the other jaw, the crushing can be particularly fine.
  • the activating means for activating the moving jaw 5 consist of a hydraulic motor 7 which drives an eccentric shaft 8 through a transmission element 9, typically a toothed belt.
  • the eccentric shaft 8 is in turn integral with a moving side support 10, which is configured as a side plate parallel to the side guards 2, there being at least one moving side support 10 for each side of the bucket 1, in a transverse position with respect to the inlet 3 and outlet 4 of the material.
  • the moving side support 10 has the particularity of having two ends, one of them being integral with the eccentric shaft 8, whereas the opposite end has an inverted C-shaped opening 12 hosing respective bolts 11, one for each moving side support 10 on each side of the bucket 1, as mentioned above.
  • the motor 7 when the motor 7 receives hydraulic pressure, preferably from the machine for public works itself, it transmits its rotation to the eccentric shaft 8 which, as a result of its own eccentric configuration, imparts an eccentric rotational movement to the moving side supports 10, which are integral with both the eccentric shaft 8 and the moving jaw 5 itself.
  • the bolts 11 are configured for limiting the movement exerted by the eccentric shaft 8 to a single degree of freedom, that rotational movement being transformed essentially into a rectilinear movement in the direction marked by the inverted C-shaped opening 12, given that, as can be observed in Figure 1 , there is a certain space which enables relative movement of the moving side support 10 with respect to the bolt 11.
  • the indicated configuration allows concentrating the entire force vector generated in the eccentric shaft 8 in one and the same rectilinear movement, whereby a substantially linear movement can be imparted in the moving jaw 5, pressing the material against the fixed jaw 6 with a homogeneous pressure on the entire contact surface, with a greater force than in other crusher buckets described in the state of the art.
  • the bucket 1 is completed with a plurality of protections and elements having a modular configuration, such that they can be readily replaced in the event of wear or breakage.
