Definitions

• the present invention relates to equipment for the stabilization and composting of organic refuse.
• equipment of this type comprises a truck designed to support a hopper for loading organic refuse.
• a filling bell Fixed with respect to the truck is a filling bell, on which the mouth of an elongated plastic bag can be fixed.
• a roll carrier on which a roll of a perforated pipe is wound, which is unrolled with the elongated bag as the truck is displaced forwards and as the elongated plastic bag is filled with the organic refuse.
• air is sent through the perforated pipe, once filling of the elongated bag has taken place, in order to accelerate the aerobic reactions of decomposition of the organic refuse, reactions that lead to the formation of the compost.
• the filling bell is once again fixed to the self-propelled truck, so that each piece of equipment can fill just one elongated bag. If it were desired to abandon a first partially full bag (which is to receive a first type of organic refuse) temporarily in order to fill a second bag (for example, with a second type of organic refuse) , the entire self-propelled equipment must be disconnected from the first bag, the first bag must be closed, the equipment must be displaced in the proximity of the second bag, and the second bag must be fitted onto the equipment itself, where the operations of filling can finally start. These operations have a high cost in terms of working hours of the operators responsible for manoeuvring the equipment. Another possibility is constituted by having a number of self- propelled pieces of equipment equal to the number of bags to be filled with inorganic refuse of various origin.
• current equipment can carry only one roll of perforated pipe, whilst in current solutions a plurality of perforated pipes are provided for blowing air into the refuse, to send the used air and possible gases away from the mass of the refuse to eliminate the percolated liquid, etc.
• the aim of the present invention is to provide equipment ⁇ for composting organic refuse which will be free from the drawbacks described above and, at the same time, will be easy and inexpensive to produce.
• FIG. 1 is a three-dimensional front view of equipment for composting organic refuse forming the subject of the present invention
• FIG. 2 shows a three-dimensional rear view of a loading truck and a filling bell that form part of the equipment of Figure 1;
• FIG. 3 is a three-dimensional front view of just the loading truck illustrated in Figures 1 and 2 ;
• Figure 4 shows a two-dimensional front view of the filling bell illustrated in Figures 1 and 2 ;
• FIG. 5 is a three-dimensional front view of a filling bell, as illustrated in Figures 1 and 2 and of an auxiliary trolley which also belongs to the equipment of Figure 1;
• FIG. 6 is a three-dimensional rear view of the filling bell and of the loading trolley represented in Figure 5;

• Associated to the loading truck 20 are traditional motor-drive means (not illustrated) , designed to render the truck 20 itself self-propelled as a result of the commands imparted by an operator (not illustrated) .
• the platform PN envisages a hopper TR, through which the organic refuse is conveyed by gravity towards a motor-driven screw-conveyor device CL ( Figures 1 and 3), designed to cause the organic refuse to advance from the unloader of the hopper TR towards the filling bell 40.
• CL motor-driven screw-conveyor device
• two roll carriers PRl, PR2 are located at a first longitudinal side LTl of the loading truck 20, whilst just one roll carrier PR3 ( Figure 2) is located at a second longitudinal side LT2 , once again of the loading truck 20.
• the filling bell 40 comprises a load-bearing structure 41, comprising, in turn, two metal elements 42, 43, both having the shape of a U turned upside down, brought up to one another and welded together so as to form a portal PT.
• the load-bearing structure is supported by a base BS ( Figures 7 , 8 and 9 ) .
• a top outer surface SS and two lateral outer surfaces SL are defined on said portal PT.

• top part of the portal PT (underneath the top outer surface SS) are three identical through holes 50, 51, 52 having a first cross section (first type of holes) and four through holes 53, 54, 55 and 56 having a second cross section of a width (second type of holes) smaller than that of the first cross section ( Figure 4) .
• through holes 54, 55 of the second type have been provided between two respective pairs of contiguous holes 50, 51 and 51, 52, whilst through holes 53, 56 of the second type are located on the outside, respectively, of through hole 50 (of the first type) and of through hole 52 (which is also of the first type) .
• the top outer surface SS of the portal PT supports five roll carriers PR4, PR5, PR6, PR7 , PR8 for respective rolls RT4,
• first steel plate 44 supports another four roll carriers PR9 , PRlO, PRIl, PR12 for respective rolls RT9, RTlO, RTlI, RT12, of respective perforated pipes TB9, TBlO, TBlI, TBl2.
• the four roll carriers PR9, PRlO, PRlI, PR12 are set in pairs on opposite sides with respect to the centred circular hole 45 provided on the first steel plate 44.
• - TBlI is inserted in through hole 54 made in the top part of portal PT; and - TB12 is inserted in through hole 53' made in the top part of portal PT.
• the perforated pipes TB5, TB6, TB7 serve, instead, to suck air and other gas out of the mass undergoing decomposition, whilst perforated pipes TB2 , TB3 are used for collecting (by means of suction) the percolated liquid that develops in the mass of the refuse during composting.
• perforated pipes TB9 , TBlO, TBlI, TB12 (having a diameter smaller than that of the others) serve for reinjecting (via means not represented) a given amount of percolate into the mass undergoing decomposition so as to maintain a certain degree of moisture therein.
• a support 57 made up of bar-like elements and provided with four feet 58, reclinable according to a respective arrow Fl, and provided with height-adjustment means (not illustrated) for the purposes that will be detailed in what follows.
• filling bell 40. is connected to/disconnected from loading truck 20 by fast-attachment/detachment means (not illustrated) similar to the ones used for hitching/unhitching a lorry to/from its own trailer.
• bag SC is simultaneously filled with refuse, pushed by motor-driven screw-conveyor device CL through centred circular hole 45.
• perforated pipes TBl, TB2 , TB3 , TB4, TB5, TB6, TB7, TB8 , TB9, TBlO, TBlI, and TB12 are progressively unrolled and are immersed in the mass of refuse contained within bag SC.
• auxiliary trolley 60 comprises a load-bearing scaffolding structure 61 comprising bar-like elements and having four legs 62 , each provided with a respective wheel 63 to enable displacement thereof over the working terrain. Legs 62 are flared downwards to bestow a greater stability upon load-bearing structure 61.
• auxiliary trolley 60 is provided with motor means (not illustrated) guided from the ground by the operator.
• Load-bearing structure 61 is, in its turn, shaped in such a way as to define a top platform PS delimited by two pairs of bars LSI, LS2, which support a treadable griddled plate GR accessible from beneath by means of a ladder SCT ( Figures 7, 8 and 9) .
• LSI bars LSI
• LS2 treadable griddled plate GR accessible from beneath by means of a ladder SCT ( Figures 7, 8 and 9) .
• a ladder SCT Figures 7, 8 and 9
• Auxiliary trolley 60 substantially serves two purposes: (A) - the first purpose is to support three roll carriers PRl3, PRl4, PRl5, which each support a possible respective roll RT13, RT14, RT15 of a possible respective perforated pipe TB13, TB14, TB15; in effect, roll carriers PRl3 , PR14, PR15 are actuated by a motor with variable-speed drive (not illustrated) provided with a clutch; if the clutch is set in the "idle" position, perforated pipes TB13, TB14 and TB15 can be unrolled and feed, respectively, roll carriers PR5, PR6, PR7 , mounted on filling bell 40.
• the motor with variable-speed drive causes roll carriers PR13 , PR14, PR15 to rotate in the direction indicated by an arrow F3 ( Figure 5) to recover perforated pipes TB5, TB6, TB7 from a bag SC filled with compost, already formed;
• FIG. 7 the second purpose .
• a hoist PC which comprises two vertical ropes FN, a device SD for supporting and gripping top flap LB, and means (not illustrated) for movement upwards in the direction indicated by an arrow F4 of supporting device SD.
• the supporting device SD comprises two brackets SF welded to a cap DD, the profile of which substantially reproduces that of top outer surface SS of portal PT. Consequently, as illustrated in Figures 7, 8 and 9, once top flap LB of the mouth BC has been rested on cap DD, said top flap LB is pulled upwards by means of hoist PC ( Figure 8) in the direction indicated by the arrow F4. At this point, it is possible to displace auxiliary trolley 60 in the direction indicated by an arrow F5 ( Figure 9), and insert portal PT in mouth BC of bag SC. Now, it is possible to fix mouth BC to surfaces SS and SL of portal PT. Once bag SC is fixed to filling bell 40, auxiliary trolley 60 is moved away from the rest of equipment
• filling bell 40 serves to support said filling bell 40 in an adequate way when it is detached from the loading truck 20. Furthermore, the presence of means (not illustrated) for adjustment of the height of feet 58 enables filling bell 40 to be set level during the steps in which the latter stops and is detached from by loading truck 20. In addition, when filling bell 40 is attached to loading truck 20, feet 58 are raised in the direction indicated by arrow Fl, and fixed in a substantially horizontal position to prevent any interference with the ground during displacements in the direction indicated by arrow F2.
• One of the main advantages of the present equipment 10 is, as has been said, that of being able to have just one loading truck 20 ⁇ (and possibly just one auxiliary trolley 60) for serving a plurality of filling bells 40, to which a respective bag SC has been fixed.
