Definitions

  • the methods and/ or procedures currently commonly carried out for the repair of road floorings, in particular tarmac comprise the execution - usually according to a predefined sequence - of various processing operations.
  • the road flooring at one or more holes and/ or low areas and/ or subsiding areas, is first milled usually with a stand-alone milling machine, wherein then the debris resulting from the milling is removed and loaded onto means of transport, wherein finally the portion of flooring previously milled and from which the debris was removed, is renewed, for example by means of laying a new tarmac layer.
  • a first problem is related to the fact that even the removal of the debris resulting from the milling of the portion or strip of flooring previously milled requires the use of a specific piece of equipment or alternatively, the manual removal of the debris.
  • problems related to the mechanized removal of the debris with the aforesaid specific pieces of equipment arise from the fact that buckets of known type may not be used for the removal of the debris and loading onto means of transport, the width of the bucket in many cases being larger than the strip of previously milled flooring.
  • bucket 100 therein depicted being in particular of the so-called "four-in- one" type and therefore inclusive of a shell shaped so as to collect bulk materials from the ground such as debris (according to essentially known operations and therefore not described in detail for the sake of conciseness), said shell comprising in particular a first half- shell 102 and a second half- shell 101 rotatably constrained to the first half-shell 102 and therefore being rotatable between the closed position in figure 1 and the open position in figure 2.
  • Buckets of the "four-in-one" type depicted in figures 1 and 2 allow the facilitated loading of even small quantities of bulk material, wherein first the material is accumulated with the bucket set in closed position and then it is conveyed and loaded into the shell by switching the half-shell 101 from the open position in figure 2 to the closed one in figure 1.
  • the width of bucket 100 in particular the extension thereof in the direction transverse to the symmetry plane of machinery 200, usually is greater than the width of a common milling machine and therefore of the strip (the bucket usually also being wider than machinery 200) whereby the debris resulting from the milling within the milled portion or strip of flooring may not be piled up or even collected by means of the bucket which contrarily, may be lowered to the greatest extent up to coming in contact with the flooring at the sides of the milled portion, and therefore without any possibility of involving or engaging the material within the strip.
  • one object of the present invention is to make available a bucket with improved versatility designed to be used both according to usual methods (as true bucket, possibly of the "four-in-one” kind) but also to allow at least the accumulation of bulk materials in situations of limited space in which the use of a bucket according to the prior art would not be possible, in particular in portions of floorings with sizes that are incompatible with the ones of a bucket according to the prior art, thereby avoiding the use of a specific piece of equipment for removing the debris.

  • bucket 100 comprises movement means 1 13, in particular a first hydraulic jack 1 13 for moving a mobile plate 1 14 and a second hydraulic jack 113 for moving the other mobile plate 1 14, wherein the extension or lengthening and shortening of the jacks 1 13 translates into the return of the respective mobile plate 1 14 (and therefore of the respective blade or mobile sheet 106) towards the retracted position in figure 3a and into the exit or extension of the respective mobile plate 1 14 (and therefore of the respective blade or mobile sheet 106) towards the advanced or extended position in figure 3b, respectively.

  • a further peculiarity of bucket 100 according to the present invention relates to the fact that the mobile blades 106, in the extended position thereof (figure 3b), extend beyond the overall dimensions of shell G, in particular underneath the bottom wall 108, while contrarily, in the retracted position thereof (figure 3a), the two blades 106 are positioned within the overall dimensions of shell G, in particular substantially within the internal space defined by shell G intended to contain the materials to be moved by means of bucket 100.

  • Letter P in figures 5 to 9 identifies a flooring (for example but not necessarily, a tarmac road flooring), while reference PI identifies a portion or strip of flooring P subjected to processing, for example a portion or strip PI at holes or subsiding areas of flooring P in which the tarmac was milled or ground and is to be removed.
  • the width of the milling machines commonly used to mill or grind the tarmac is significantly less than the one of buckets of the type according to the present invention; it is therefore apparent that debris M resulting from the milling, which remains confined in portion PI and underneath the level of the original surface S of flooring P, may not be removed from portion PI by means of a bucket of known type, the bucket indeed, as depicted in figures 1 and 2, may be at most resting on the surface S of flooring P, and therefore in absolutely unsuitable position to engage and collect material M in and from portion PI, respectively.
  • the bucket according to the present invention allows this limitation of buckets according to the prior art to be overcome.
  • the material M in portion PI may be engaged by at least one of the mobile blades 106 (one or more according to the width of the strip PI) in intermediate position between the retracted position in figure 3a and the extended position in figure 3b, according to the actual depth of portion PI (figures 5b and 5c).
  • material M may be engaged by means of one or both the mobile blades 106 and therefore accumulated and pushed outside the milled portion PI, and then collected by means of bucket 100 itself according to habitual and variable operations depending thereon whether or not the bucket is of the type with shell G in a single piece or, as depicted, of the "four-in-one" type.
  • Figures 5, 6 and 9 relate to the case in which the width of portion PI requires the use, and therefore the extension, of one mobile blade 106 alone (the width of the portion or strip PI being only slightly greater than the one of a mobile blade 106), while figures 7 and 8 relate to the case in which the width of the strip PI is such as to require the use and the extension of the two mobile blades 106, like when the strip PI is processed by means of two contiguous passages with the milling machine.
  • material M under the push of one or both the two mobile blades 106, is pushed outside portion PI, at least partly over surface S at the sides of portion PI, from where it may be collected by means of bucket 100, in particular by means of shell G.
  • bucket 100 allows the need to be obviated of arranging a specific piece of equipment, for example, a piece of suction equipment, or in any case of resorting to the manual removal of material M.
  • the piece of equipment 300 later also defined as “lime spreader” comprises a container or hopper 301 with a cover 310, the container 301 being intended to contain the materials C to be distributed.
  • a through slit of longitudinal extension substantially equal to the width of container 301 is formed on the bottom of container 301 (figure 13), wherein, there are prepared rotary dosing means 302 at the through slit 31 1, in the specific case consisting of a drum with a plurality of blades that extend outwards from the drum itself, wherein therefore the rotation of the means 302 allows the exit of material C through slit 31 1.
  • the driving in rotation of the means 302 is obtained by means of driving in rotation of the wheels 304 and of a drive (not depicted) interposed between at least one of the wheels 304, wherein therefore the rotation speed of the means 302 depends on the drive ratio between the at least one wheel 304 and the means 302, and wherein the rotation of the wheels 304 is obtained simply by means of translation (by thrust and/or traction) of the piece of equipment 300 with the wheels 304 in contact with the ground, for example with the surface S of flooring P or also with the surface of portion PI previously freed of debris M resulting from the milling.
  • the piece of equipment 300 may obviously be manually pushed and/or pulled, for example by acting on handle 312.
  • the piece of equipment 300 according to the present invention is shaped so as to be moved (pushed and/or pulled with the wheels 304 in contact with the ground, for example with surface S) by means of the above- described bucket according to the present invention.
  • the piece of equipment 300 is shaped so as to define a housing and engagement portion 305 intended to be engaged by bucket 100, in particular so as to at least partially house the bottom wall 108 of shell G (with the half-shell 101 in closed position in case of "four-in-one" type of shell).
  • the engagement portion 305 is defined by a bottom wall 307 and by a top wall 308 (for example, the bottom wall of container 301), the walls 307 and 308 being radiused at an end portion 306 of the engagement portion 305 designed in particular to be engaged by the front fixed blade 105 of bucket 100.
  • Bucket 100 is progressively moved close to the piece of equipment 300 so as to progressively insert the bottom wall 108 of bucket 100 into the engagement and housing portion 305 of the piece of equipment 300 (figure 10a); then, with the end portion 306 engaged by the front blade 105 of bucket 100, and with the bottom wall 108 substantially housed between said end portion 306 and a projection 309 that extends from wall 108 towards the top wall 308, one or both the mobile blades 106 (according to the width of the piece of equipment 300) are switched from the retracted position into an intermediate position in which they engage the bottom wall
  • bucket 100 in particular the bottom wall 108, cannot come out of the portion or engagement and housing seat 305, and the piece of equipment 300 is rigidly constrained to bucket 100 by contrast between the parts engaged together, in particular between blade 105 and the end portion 306, between the bottom wall 108 of shell G and the bottom wall
  • the piece of equipment 300 may be released from bucket 100 by bringing one or both mobile blades 106 back into the retracted position (or in any case, the disengagement position from projection 309) and retracting the bucket with respect to the piece of equipment 300.
  • the piece of equipment 300 may also be easily loaded and unloaded onto and from, respectively, a means of transport, for example a truck or semi-trailer. It has therefore been shown how the combined system of the piece of equipment 300 and bucket 100 according to the present invention allows the problem to be obviated of arranging specific movement means for moving the lime spreader 300.
  • various pieces of equipment may be moved by means of methods similar to the ones described above, for example a piece of equipment for the distribution of fluid materials or liquids, or also for example, a milling machine provided with an autonomous engine or with a pump or hydraulic motor which can be connected to the hydraulic circuit of machine 200, the pieces of equipment only requiring to be provided with an engagement portion corresponding to the engagement portion 305 described above with reference to the lime spam 300 for the purpose.
  • the present invention allows the repair and/ or renewal of floorings to be improved and simplified, in particular but not exclusively, of road floorings made of tarmac, at holes and/ or subsiding areas and/ or similar irregularities.
  • the present invention allows the facilitated removal of debris M from previously milled portions of flooring PI, and also the just as facilitated execution of operations and/or processing operations in the aforesaid portions PI .
  • a non-limiting example of repair and / or renewal of a road flooring P may comprise the following operations:
  • portion PI removing debris M from portion PI (possibly comprising the load of material M and transferring to areas provided for the purpose, e.g. landfills);
  • the milling and removal operations a) and b) of debris M are part of the preparation of portion PI, while the renewal of portion PI may for example, but not necessarily and/or exhaustively, comprise the following operations: c) distributing melted binding material in portion PI such as for example, cement and/or lime (for example, by means of the piece of equipment 300 described above);
  • operations b), f), h) and i) may be conveniently executed by means of bucket 100 according to the present invention, with one or both the mobile blades 106 in retracted or intermediate or extended position according to the needs and / or circumstances;
