Description
Domanda di Brevetto per invenzione Industriale Patent Application for Industrial Invention
- denominata Dispositivo per automatizzare il sollevamento della barra antiribaltamento dei trattori agricoli - called Device for automating the lifting of the anti-tip bar of agricultural tractors
L?invenzione presentata nella documentazione che segue ? finalizzata al perfezionamento ed aH?automazione dei sistemi di sicurezza impiegati attualmente su trattrici agricole e macchine operatrici con delle applicazioni facilmente montabili su ogni tipo di macchina, poco ingombranti e non eccessivamente costosi, realizzabili anche in kit predisposti per ogni ?tipo di macchina. The invention presented in the following documentation? aimed at the improvement and automation of the safety systems currently used on agricultural tractors and operating machines with applications that can be easily mounted on any type of machine, not bulky and not excessively expensive, also available in kits prepared for any type of machine.
I sistemi attualmente in uso sono delle barre antiribaltamento sollevabili manualmente a macchina ferma e quindi praticamente inutili se si verificasse un incidente di ribaltamento in colture ove non ? possibile lavorare con la barra sollevata per motivi di ingombro, The systems currently in use are anti-overturning bars that can be lifted manually when the machine is stopped and therefore practically useless if a overturning accident occurs in crops where not? it is possible to work with the bar raised for reasons of space,
Alcuni sistemi prevedono il sollevamento della barra anti ribaltamento con pi? cilindri e di conseguenza lenti in caso di intervento avendo bisogno il circuito di una quantit? di olio abbastanza rilevante pertanto i sistemi risultano poco affidabili. Some systems provide for the lifting of the anti-overturning bar with more? cylinders and consequently slow in case of intervention as the circuit needs a quantity? of quite significant oil therefore the systems are not very reliable.
Di seguito andiamo a descrivere ed illustrare l?invenzione in un?esecuzione preferita non limitativa di ulteriori perfezionamenti nell?ambito dei brevetto con l?aiuto delle seguenti figure: Below we are going to describe and illustrate the invention in a preferred non-limiting embodiment of further improvements in the field of patents with the help of the following figures:

Nella parte che segue si descrivono i componenti meccanici elettroidraulici e il loro funzionamento: il sistema viene alimentato dalla pompa (11) del trattore che ? collegata al distributore (13) dello stesso, per attivare il meccanismo in oggetto viene inserito un rubinetto (12) sulla linea di alimentazione fra pompa (11) e distributore (13), chiudendo il rubinetto (12) esclude il distributore (13) deviando il flusso verso il sistema in oggetto, attraversando una valvola di ritorno (10) alimenta un accumulatore di energia (7) il quale ? collegato a una elettrovalvola (6); per evitare sovrappressioni fra l?elettrovalvola (6) e l?accumulatore di energia (7) vi ? montata una di valvola massima ( 15) la quale invier? a scarico il fluido in esubero. The following section describes the electro-hydraulic mechanical components and their operation: the system is powered by the tractor pump (11) which? connected to the distributor (13) of the same, to activate the mechanism in question, a tap (12) is inserted on the supply line between the pump (11) and the distributor (13), closing the tap (12) excludes the distributor (13) by diverting the flow towards the system in question, passing through a return valve (10) feeds an energy accumulator (7) which? connected to a solenoid valve (6); to avoid overpressure between the solenoid valve (6) and the energy accumulator (7) there? mounted a maximum valve (15) which will send? when the excess fluid is discharged.
Quando l?accumulatore (7) sar? carico, verificabile grazie al manometro (14), aprendo il rubinetto (12) si ripristina il normale funzionamento del distributore (13), lasciando il sistema pronto per eventuali interventi. When the accumulator (7) will be? load, verifiable thanks to the pressure gauge (14), opening the tap (12) restores normal operation of the distributor (13), leaving the system ready for any interventions.
Nel momento in cui il trattore supera il limite critico d? inclinazione un dispositivo di rilevamento di inclinazione elettrico (8) invia un impulso aH?elettrovalvola (6), la quale apre il circuito idraulico cos? permettendo alfiaccumulatore di energia (7) di inviare il fluido in esso contenuto ad una pressione predeterminata, verificabile grazie al manometro (14), al cilindro (5), fissato ad una estremit? alla barra (1) con una staffa snodata (4) e all?altra estremit? ad una staffa (3) con uno snodo, il quale aiutato da una molla (9) si estende sollevando la barra antiribaltamento (1 ) a velocit? di intervento utile e sicura, regolabile per mezzo di una valvola di regolazione di flusso (16). When the tractor exceeds the critical limit d? inclination an electric inclination detection device (8) sends an impulse to the H? solenoid valve (6), which opens the hydraulic circuit cos? allowing the energy accumulator (7) to send the fluid contained in it at a predetermined pressure, verifiable thanks to the pressure gauge (14), to the cylinder (5), fixed at one end? to the bar (1) with an articulated bracket (4) and to the other end? to a bracket (3) with a joint, which aided by a spring (9) extends by lifting the anti-tipping bar (1) at speed? useful and safe intervention, adjustable by means of a flow regulation valve (16).
Per evitare che la barra (1) si abbassi nella violenza dell? impatto con il terreno, il cilindro (5) ? dotato anche di una valvola di blocco (17) utile anche quando la barra (l):? in posizione di riposo. Per ripristinare il circuito bisogna azionare un interruttore elettrico (18) il quale ? collegato all?elettrovalvola (6) escludendo momentaneamente il dispositivo di inclinazione (8) apre il circuito al contrario permettendo al cilindro (5) di abbassare la barra antiribaltamento (1) riportandola in posizione di riposo originale. To avoid that the bar (1) is lowered in the violence of the? impact with the ground, the cylinder (5)? also equipped with a block valve (17) also useful when the bar (l) :? in rest position. To restore the circuit it is necessary to operate an electric switch (18) which? connected to the solenoid valve (6) by temporarily excluding the tilting device (8), it opens the circuit in reverse allowing the cylinder (5) to lower the anti-tipping bar (1) returning it to its original rest position.
Rifacendo le operazioni indicate all? inizio della descrizione si ripristina il sistema rendendolo pronto ad intervenire in caso di ribaltamento. By repeating the operations indicated in the beginning of the description the system is reset making it ready to intervene in case of overturning.
11 rubinetto (12) pu? essere sostituito da una elettrovalvola (19) e aggiungendo un pressostato anche l?operazione di ripristino sistema pu? essere ulteriormente automat?zzato. 11 tap (12) can be replaced by a solenoid valve (19) and by adding a pressure switch also the system restore operation can? be further automated.
Il cilindro (5) e la molla (9) possono essere anche sostituiti dal cilindro (22) e dalla molla (21)i cilindro (24) e dalia molla (23), dal cilindro doppio stelo (25) con supporto contenitore molla (27) e dalla molla (26). The cylinder (5) and the spring (9) can also be replaced by the cylinder (22) and by the spring (21) the cylinder (24) and by the spring (23), by the double rod cylinder (25) with spring container support ( 27) and the spring (26).
