2. A conveyor according to claim 1, wherein the frame of the first section of the conveyor is carried by a supporting means comprising a vertical shaft pivotally mounted into a sleeve securely connected to the said bracket and which carries through a fork-like arm the charging end of said first section of the conveyor by means of two coaxial pins having a horizontal axis which is set a right angle with respect of the longitudinal vertical center plane of the conveyor, said pins constituting the second hinge having a horizontal pivot axis, a first disconnectable locking means being provided in order to lock the fork-like arm to said frame of the first section so as to make inoperative the second hinge having a horizontal axis in the substantially vertical position of said first section of the conveyor, a second disconnectable locking means being further, provided to lock said sleeve to said supporting shaft, said first and second locking means being constituted of holes arranged in said sleeve and shaft respectively and designed for coming into register and to house a locking pin.
3. A conveyor according to claim 1, wherein the first articulation hinge having a horizontal axis is arranged in the lower part of the adjacent ends of the first and second frames forming the carrying structure over which is entrained the endless band, while at the upper part of them lugs are provided where holes having horizontal axes are arranged designeD for coming into register, when said sections are arranged in line, so as to receive a removable locking pin.
4. A conveyor according to claim 1, wherein the rotation of the second section of the conveyor with respect to the first one around the pivot axis of the first hinge having a horizontal axis, when are made inoperative by the respective locking means the other hinge having a horizontal axis as well as the second hinge having a vertical axis, or the rotation of the whole conveyor with regard of the first hinge having a vertical axis and made operative by the removal of the corresponding locking means when the said first hinge having a horizontal axis has been locked, is carried out by said first driving means constituted of a jack articulated at one of its ends to an arm securely connected to a fork-like supporting means of the conveyor, and at the other end to an intermediate point of the second section of said conveyor.
5. A conveyor according to claim 1 to be used in combination with a rotating mixer and the like carried by the same wheeled frame, characterized by the fact that the articulated guiding system further carried a discharge distribution chute of an angularly displaceable type, said system being arranged in such a manner that said chute is positioned below the discharge opening of the mixer, when the conveyor is in its inoperative position, while automatically is moved away from said opening in order to allow that the charging end of the conveyor can replace said chute below the discharge opening of the mixer, in any working position of the conveyor, said articulated system being pivotally connected at one of its ends to the framework which is securely fixed to the wheeled frame of the vehicle, and at the other end to an arm outwardly projecting from the sleeve, into which is pivotally mounted the fork-like supporting member carrying the conveyor through the second hinge having a horizontal axis, at the end of said arm being arranged a vertical hole designed for coming into register with an analogous hole provided into a bracket integral with the stationary framework of the vehicle in the arrangement of the parts, wherein the charging end of the conveyor is so positioned as to be able to receive the material, said holes being designed for receiving a removable locking pin.
6. A conveyor according to claim 1, wherein the lower end of the shaft of the fork-like supporting member is further made integral with an outwardly projecting arm to which is articulated a jack which constitute the second driving means and which is articulated at the other end to the stationary framework of the vehicle, said jack, when are made operative the means provided for locking the guiding system and the means provided for locking the first and second hinges having a horizontal axis respectively and has been removed the pin locking the shaft of the fork-like member to the supporting sleeve, forces said supporting member together with the conveyor to rotate around the vertical axis of the second hinge having a vertical axis with respect to the said sleeve and to the bracket integral therewith.
7. A conveyor according to claim 1, wherein the conveyor is constituted of two sections.
8. A conveyor according to claim 1, wherein the conveyor is constituted of three sections, interconnected by means of hinges having parallel and horizontal axes which are set at right angle with respect to the longitudinal vertical center plane of the conveyor, that hinge which is arranged between the first and second sections being positioned near the lower surface of said sections, while the other hinge is arranged near the upper surface of the second and third sections.
9. A conveyor according to claim 1, wherein the three sections constituting the carrying structure of the conveyor are associated with a rod guiding system adapted to co-ordinate the movements of said sections and to force the second section rotate with respect to the first one in one direction through an angle of aBout 90*, at the same time the third section is forced to rotate through an angle of 180* in the opposite direction with respect to the preceding one, so that when the conveyor is in its folded position, the first section is set at an angle littly higher than 90*; with respect to the second section and the third section has been pivoted in a horizontal plane and rests on the second section, while said rod system forces said sections to rotate in opposite direction for forcing said sections to be arranged in line, causing the second section to rotate through an angle of a value littly smaller than 90* with respect to the first section and the third section to rotate through an angle of 180* with respect to the second section.
10. A conveyor according to claim 1, wherein the parts designed for carrying the conveyor or for moving it from its inoperative position to an operative position and vice versa are mounted on the wheeled frame and are so dimensioned that the conveyor in its folded position together with the parts associated therewith does not exceed the whole clearance gauge of the vehicle.
