Definitions

  • the present invention concerns a guiding system for milling machine mouldboard designed to leave the milled material in a high layer on the milled surface and in particular for a milling machine for asphalt, concrete and other materials used for road pavings according to the characteristics of the pre-characterizing part of claim 1.
  • the present invention also concerns a milling machine provided with such guiding system according to the characteristics of the pre-characterizing part of claim 11.
  • a road milling machine is a self-propelled machine, of known technology, finalized to the demotition of road pavings by means of milling with a rotating milling drum.
  • a road milling machine ( Figs. 1 , 2 ) is generally equipped with a milling drum (3) contained in a milling drum housing (7) opened downwardly to ensure the contact of said milling drum (3) with the surface to be milled and frontally opened for the outflow of the milled material outside the milling drum housing (7) itself.
  • the rear part of the milling drum housing (7) is closed by a rear mouldboard (8) generally made ( Fig. 4 ) of an upper section (12) and of a lower section (13).
  • the upper section (12) is hinged at the hinging point (29) and it can rotate ( Figs. 4 , 6 , 7, 8 ) around a horizontal axis, parallel to the rotating axis of the milling drum (3), the rotation being generally operated by two mouldboard operating pistons (24), which in the illustrated embodiment are two hydraulic pistons.
  • the lower section (13) slides over the upper section (12), being engaged to this by means ( Fig. 3 ) of two slot guides (15). Moreover, the lower section (13) is also guided ( Figs. 3 , 4 , 6 , 7 ) by two cam-profiles (16) fitted on the first side wall (26) and second side wall (27) of the milling drum housing (7). Said cam-profiles (16) force the mouldboard lower section (13) to move vertically for a certain distance. Then the lower section (13) is disengaged from the lateral cam-profiles (16) and it rotates along with the upper section (12), both vertical and rotating movements being supported by said two mouldboard operating pistons (24).
  • the lower section (13) of the rear mouldboard (8) is provided with scraping tools (20) and it is generally in contact with the milled surface, being forced downwards by a controlled pressure of mouldboard operating pistons (24) and acting as a scraper to clean the milled surface.
  • the rear mouldboard (8) is generally opened, when the machine is stopped, to get the access to the milling tools for their replacement.
  • the rear mouldboard (8) is in contact with the milled surface and contributes to transfer the milled material from the milling drum housing (7) onto ( Figs. 1 , 2 ) a conveyor system (30), which in the illustrated embodiment comprises a collecting conveyor (5) and a loading conveyor (6).
  • the milled material (23) must be left ( Figs. 6 , 7 , 11 ) on the milled surface, for example for the so-called “in situ” recycling of the milled material (23).
  • the normal operating practice consists of:
  • the invention has the following aims:
  • the present invention does not require any modification of the design of the drum housing (7)
  • the milling machines answer this need, being machines specially conceived for the removal of the old pavement before the laying of the new mat.
  • the road milling machine ( Figs. 1 , 2 ) consists of a self-propelled chassis (1) supported on tracks (2), or wheels, generally equipped with hydraulic drives that pull power from an engine, which is usually a diesel engine.
  • the milling drum (3) is supported by the chassis (1), transversely to the advancement direction (14) of the machine and is activated by the engine through a mechanical transmission, or by a hydraulic transmission.
  • the tracks (2), or wheels, are connected to telescopic columns (4), by means of which the chassis (1) is brought to height and set to obtain the correct milling profile.
  • the material milled by the milling drum (3) is removed from the milling drum housing (7) by means of a conveyor system (30) consisting of one or two conveyors (5, 6) and it can be discharged at the forepart of the machine or at its back. In the first case the material is discharged on means of transportation that precedes the milling machine, while in the second case the means of transportation fellows the milling machine proceeding in reverse motion.
  • the description of the invention refers to its application on a road milling machine with frontal charge of known technology ( Figs. 1 , 2 ), in which the milling drum (3) is contained in a drum housing (7).
  • the drum housing (7) is provided with a movable rear mouldboard (8), provided with scraping tools (20) for the cleaning of the milled surface, and it is also provided with two movable side plates (9, 10) in contact with the road surface, with floating or slightly forced action.
  • an opening (28) is provided ( Fig. 2 ), which allows the discharging of the milled material onto a first conveyor belt, which is generally identified as the collecting conveyor (5).
  • the rear part of said collecting conveyor (5) is supported by a device commonly known with the name of pressure bar (11), which is generally kept in a more or less forced contact condition with the surface to be milled, and the forepart of which slides on a support connected to the chassis (1) of the machine.
  • the collecting conveyor (5) discharges the milled material onto a loading conveyor (6) which can be slewed vertically and horizontally to adapt its discharge head to the height and position of the transport vehicle, changing the position of the discharge point (25) with respect to the position of the chassis (1) of the machine.
  • the machine is equipped with a conveyor system (30) comprising at least one conveyor.
  • the rear mouldboard (8) is divided ( Fig. 3 ) into two sections, a lower section (13) and an upper section (12).
  • the lower section (13) can be vertically moved and the upper section (12) can rotate ( Figs. 4 , 6 , 7 ), along with the lower section (13), around a horizontal axis at a hinging point (29).
  • the vertical movement of the lower section (13) allows maintaining the lower section (13) of the rear mouldboard (8) in contact with the milled surface with a floating or forced action, but for particular operative needs the rear mouldboard (8) may be also held partially raised to leave the milled material (23) flow below it.
  • the lower edge of the rear mouldboard (8) is provided with scraping tools (20) to clean the milled surface.
  • the rotary motion around the hinging point (29) with a horizontal axis allows the total opening of the rear mouldboard (8) to access the tools of the milling drum (3) for their replacement.
  • the total opening/closing operation of the rear mouldboard (8) is performed by two mouldboard operating pistons (24) which are arranged in a parallel way. It will be apparent that depending on the dimensions of the rear mouldboard (8) and on the particular application single central operating piston could be used, the solution with two operating pistons (24) being the preferred one.
  • the rear mouldboard (8) When the rear mouldboard (8) is in the fully opened condition, the rear mouldboard (8) can be secured in position ( Fig. 8 ) by means of a hook (22) which can be engaged with a retainer (21).
  • the scraping tools (20) should be kept in contact with the milled material (23) at any time.
  • the present invention ( Figs. 9 , 10, 11 ) has solved the above mentioned problems of the prior art machines.
  • Special auxiliary blocks (18) are fitted to the first side wall (26) and to the second side wall (27) of the milling drum housing (7).
  • the auxiliary blocks (18) are shaped as a right-angle triangularly shaped body in which the hypotenuse ( Figs. 9 , 10 ) essentially constitutes a by-pass fourth surface (34) which allows to by-pass the third surface (33) of the lateral cam-profiles (16) during the movement of the lower section (13) of the rear mouldboard (8).
  • One of the right-angled sides of the right-angle triangularly shaped body of the auxiliary block (18) goes in an abutment condition with the third surface (33) of the lateral cam-profiles (16), contributing to the release of the force applied to the auxiliary blocks (18) by the lower section (13) through the cursor (17).
  • the by-pass fourth surface (34) of the auxiliary blocks (18) forms an extension of the second surfaces (32) preventing the cursors (17) from sliding on the third surface (33) and guiding the movement of the cursors (17) in a vertical direction, thus preventing the rear mouldboard (8) from rotating around the hinging point (29) and causing the rear mouldboard (8) to further move in the vertical direction without starting to rotate around the hinging point (29). In this way the vertical stroke of the rear mouldboard (8) is extended.
  • an increased flow of the milled material (23) under the scraping tools (20) is allowed when the cutting depth is about 200 mm or more.
  • the rear mouldboard (8) can be kept in a working position also when the cutting depth is about 200 mm or more, thus preventing the possible access of the workers to a very dangerous area and avoiding the inefficient containment of the milled material, which, otherwise, could be spread around by the milling drum (3) rotation.
  • the auxiliary blocks (18) are connected to the first side wall (26) and to the second side wall (27) of the milling drum housing (7) by means of a quick fastening system (19), which allows the auxiliary blocks (18) to be rapidly and easily removed to restore the full rotation condition of the mouldboard (8) in order to allow the access to the milling drum housing (7) only in case safety conditions are ensured.
  • the auxiliary blocks (18) provide means to extend the stroke of the lower section (13) of the rear mouldboard (8), vertically extending the length of the lateral cam-profile guides (16).
  • the auxiliary blocks (18) are quickly removable to allow the full opening of the rear mouldboard (8) up to the engagement of the safety hook (22) with the retainer (21).
  • the quick fastening system (19) consists of a spacer (39) supporting a head (40).
  • Each of the auxiliary blocks (18) is provided with two spaced fastening systems (19).
  • each of said slotted holes (36) consisting of an enlarged portion (37) and a slotted portion (38).
  • the axis of the slotted portion (38) of one of the slotted holes (36) is parallel to the axis of the slotted portion (38) of the other one of the slotted holes (36) of said couple of slotted holes (36).
  • the auxiliary block (18) is placed ( Fig. 14 ) in correspondence with said slotted holes (36), with the heads (40) of the quick fastening system (19), which are positioned in correspondence of the enlarged portion (37) of the corresponding slotted hole (36).
  • the auxiliary block (18) is pulled backward (in the direction indicated by the arrow in Fig. 14 ) causing the spacer (39) to be inserted and to slide along the slotted portion (38) until the head (40) is prevented to exit from the corresponding enlarged portion (37) of the slotted hole (36).
  • the raising of the mouldboard (8) causes said mouldboard (8) to slide along the fourth surface (34) of the auxiliary block (18) blocking in position the auxiliary block (18) applied to the milling drum housing (7) by means of the couple of slotted holes (36).
  • the unblocking of the auxiliary block (18) is prevented by the mouldboard (8) itself, allowing to have a real fast mounting and demounting of the auxiliary blocks (18).
  • the mouldboard (8) can be obtained in a single piece, without providing a lower section (13) and an upper section (12).
  • the invention will be applicable also in the case of a single piece mouldboard (8).
  • the guiding system for milling machine mould board according to the present invention is applicable to any milling machine which is provided with a milling drum housing (7) defined at least by one first sidewall (26), one second sidewall (27) and said mouldboard (8).
  • the invention can be advantageously applied also to existing milling machines provided with a mouldboard (8) which is raisable/lowerable and rotatable around a hinging point (29) with respect to the milling drum housing (7) by means of at least one operating piston (24) between:
  • At least one sliding surface (31, 32) defines the portion of the stroke of the mouldboard (8) along which the mouldboard (8) is moved between the at least one lowered position in which the scraping tools (20) are in contact with the milled surface and the partially raised position in which the flow of the milled material (23) underneath the mouldboard (8) is allowed
  • the third surface (33) defines the position of the stroke of the mouldboard (8) from which the rotation of the mouldboard (8) begins to reach the retracted raised position in which the mouldboard (8) is rotated allowing the access to the milling drum housing (7).
  • the guiding system comprises at least one auxiliary block (18) which can be positioned in correspondence of the at least one cam-profile (16).
  • the auxiliary block (18) is provided with a fourth surface (34) which forms an extension of the sliding surfaces (32, 32) constituting a by-pass surface of the third surface (33) preventing the rotation of the mouldboard (8).
  • the raising movement of the mouldboard (8) causes the mouldboard (8) to slide along the fourth surface (34) causing the mouldboard (8) to further move in the vertical direction without starting to rotate around the hinging point (29) extending the vertical stroke of the mouldboard (8).
  • the extended vertical stroke of the mouldboard (8) defines an extended raised position of the mouldboard (8) in which the flow of the milled material (23) underneath the mouldboard (8) is allowed, said scraping tools (20) being in contact with the milled material flowing underneath said mouldboard (8) and in which the access to the milling drum housing (7) is prevented, allowing to keep the mouldboard (8) in a working position also when the cutting depth is about 200 mm or more, thus preventing the possible access of the workers to a very dangerous area and avoiding the inefficient containment of the milled material, which, otherwise, could be spread around by the milling drum (3) rotation.
  • the lower section (13) is slidable for a certain stroke with respect to the upper section (12) along slot guides (15) obtained on the upper section (12) itself.
  • the sliding of the lower section (13) corresponds to the raising/lowering movement of the mouldboard (8) between the at least one lowered position in which the scraping tools (20) are in contact with the milled surface and the at least one partially raised position in which the flow of the milled material (23) underneath the mouldboard (8) is allowed.

  • the raising movement of the lower section (13) along the fourth surface (34) causes the lower section (13) to further move in the vertical direction without the rotation of the upper section (12), extending the vertical stroke of the lower section (13).
  • the extended vertical stroke of the lower section (13) defines an extended raised position of the mouldboard (8) in which the flow of the milled material (23) underneath the mouldboard (8) is allowed, said scraping tools (20) being in contact with the milled material flowing underneath said mouldboard (8) and in which the access to the milling drum housing (7) is prevented, allowing to keep the mouldboard (8) in a working position also when the cutting depth is about 200 mm or more, thus preventing the possible access of the workers to a very dangerous area and avoiding the inefficient containment of the milled material, which, otherwise, could be spread around by the milling drum (3) rotation.
