Such a possibility? by sending them to me, changing the set-up of the tools makes the apparatus versatile also for blanking. grass on inclined planes, such as embankments, sloping terrain, road edges and more. The middle ? applicable to the tractor and takes the movement from its power take-off.

DESCRIZIONE DESCRIPTION

L'invenzione si riferisce ad un attrezzo per tranciare l'erba anche su piani inclinati che sostanzialmente impiega un braccio che regge un disco con lame rotanti. A cariando manuale e me diante un si sterra di fl?nge e snodi ? consentito di mutare l' in clinazione del braccio per l'adeguamento di assetto. Il mezzo ? applicabile al trattore e preleva il movimento dalla sua presa di forza. ?' utilizzabile pervia tranciatura dell'erba ed in par ticolare per argini, su cigli stradali e parti declive in genere. Per consentire queste lavorazioni su terreni inclinati, un attrezzo di attuale impiego consente il movimento del braccio portautensili mediante apparati idraulici. Questo sistema compor ta l'impiego di apparati di elevato peso e costo. Il trovato con sente una generale semplificazione compositiva ed una riduzione nei c?sti di produzione mediante l'impiego di braccio portautensili ad azionamento meccanico. Sostanzialmente il trovato impiega un collegamento cardanico ed un braccio con leve che consentono al disco rotante, di mantenere costantemente il suo asse parallelo all'asse di marcia del mezzo che lo traina. The invention relates to a tool for shearing the grass even on inclined planes which substantially uses an arm that holds a disc with rotating blades. A cariando manual and me diante a sterra of flanges and joints? allowed to change the inclination of the arm for trim adjustment. The middle ? applicable to the tractor and takes the movement from its power take-off. ? ' it can be used for shearing the grass and in particular for embankments, on road edges and sloping parts in general. To allow these operations on sloping ground, a currently used tool allows the movement of the tool holder arm by means of hydraulic devices. This system involves the use of high-weight and expensive apparatuses. The invention allows a general compositional simplification and a reduction in the production baskets by means of the use of a mechanically operated tool holder arm. Basically, the invention employs a cardan connection and an arm with levers which allow the rotating disc to constantly maintain its axis parallel to the travel axis of the vehicle that drives it.

Forma di attuazione viene illustrata in via puramente indicativa ai disegni della Tav. 1 ove la fig. 1 ? vista. dall'alto della apparecchiatura. E' in particolare osservabile il sistema di applicazione dell'attrezzo al trattore. La fig. 2 ? vista dello apparato di taglio. La versione prevede il prelievo del moto dal ponte differenziale 1 del trattore, tramite l'albero cardani co 2, con trasmissione mediante la cinghia 3 dalla puleggia 4 alla puleggia 5 che, in uscita, porta l'albero 6 calettato ad altro albero cardanico telescopico 7. Questo trasmette il movimento alla testa di comando 8 a rinvio angolare. In uscita dell'apparato di rinvio angolare, ? calettato il disco rotante 9 sul quale sono montati un sistema di coltelli 10 operanti in u sicita per effetto centrifugo. Quando i coltelli 10 vengono a con tatto con un ostacolo rigido, rientrano nella sede 11. In parti colare le pulegge 4 e 5 sono portate dal telaio 12 in lamiera di assiale, Queste viene rese solidale al battere secondo i tre punti di appoggio del mezzo di sollevamento del tratt?re. Sull'estremo esterno della trave 12 ? applicato il braccio di supporto del disco rotante che ? impiegabile ad inclinazione re golabile. Detto braccio ? applicato in articolazione rotante su coppia di orecchiette 13 che reggono l ' impostatone triangolare 14. Questo regge sulle articolazioni rotanti 15, 16 e 17 il brac ci? portante 18 e le leve 19 e 20, articolati a rotazione in 21, 22 e 23 al corrispondente impostatore 24 che assicura la variabilit? di posizione del disco 9. All ' impostatore 24 ? applicata la coppia di flangie 25 e 26 che consentono uno spostamento angolare a pieno angolo del disco 9 in tal modo permettendo adegua mento su quasiasi angolo' di lavoro. Per l'applioazione, si procede al montaggio dell'attrezzo sui tre punti di vincolo dell' e levatore del trattore, indi si colloga l'albero 2 alla, presa di moto. Poi si procede alla regolazione della inclinazione mediar te la coppia di flangie 25 e 26 adeguando queste alla superficie di lavorazione. In particolare l'attrezzo consente la lavorazio ne procedendo con il trattore o sulle due sponde del fosso o rimanendo su di un lato. L'adeguamento ? attuabile manualmente va riando l'inclinazione di escursione orizzontale dei bracci 18, 19 e 20. La posizione di lavorazione ? adeguatile variando la p? sizione di innesto dell'albero cardanico 7 o sul perno 6 o sul Embodiment is illustrated purely as an indication in the drawings of Table 1 where fig. 1? view. from the top of the equipment. In particular, the system for attaching the implement to the tractor can be observed. Fig. 2 ? view of the cutting unit. The version foresees the withdrawal of the motion from the differential bridge 1 of the tractor, by means of the cardan shaft 2, with transmission by means of the belt 3 from the pulley 4 to the pulley 5 which, at the output, brings the shaft 6 keyed to another telescopic cardan shaft 7. This transmits the movement to the angular transmission control head 8. At the output of the angular transmission apparatus,? keyed the rotating disk 9 on which a system of knives 10 operating in use by centrifugal effect are mounted. When the knives 10 come into contact with a rigid obstacle, they reenter the seat 11. In particular, the pulleys 4 and 5 are carried by the frame 12 in axial sheet metal, These are made integral with the hammer according to the three support points of the vehicle. lifting of the tractor. On the outer end of beam 12? applied to the support arm of the rotating disk which? usable at adjustable inclination. Said arm? applied in a rotating joint on a pair of ears 13 which hold the triangular set 14. This holds the arms on the rotating joints 15, 16 and 17? bearing 18 and levers 19 and 20, articulated in rotation at 21, 22 and 23 to the corresponding setting 24 which ensures the variability? position of the disc 9. To the setter 24? applied the pair of flanges 25 and 26 which allow a full angle angular displacement of the disc 9 thus allowing adaptation to any working angle. For the application, the tool is assembled on the three attachment points of the tractor lever, then the shaft 2 is connected to the drive. Then the inclination is adjusted by means of the pair of flanges 25 and 26, adapting these to the machining surface. In particular, the tool allows the work proceeding with the tractor or on the two sides of the ditch or remaining on one side. The adjustment? can be activated manually by varying the horizontal excursion inclination of the arms 18, 19 and 20. The machining position? adaptable by varying the p? coupling position of the cardan shaft 7 or on the pin 6 or on the
