Description

DESCRIZIONE DESCRIPTION

a corredo di una domanda di brevetto per modello di utilità avente per titolo: accompanying a patent application for a utility model entitled:

“MESCOLATORE PER CALCESTRUZZO E SIMILI IMPASTI, DOTATO DI ALBERI DI MESCOLAZIONE CON DOPPIA MOTORIZZAZIONE”. “MIXER FOR CONCRETE AND SIMILAR DOUGH, EQUIPPED WITH MIXING SHAFTS WITH DOUBLE MOTORIZATION”.

TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

La presente domanda di brevetto per modello di utilità ha per oggetto una mescolatore per calcestruzzo e simili impasti, dotato di due alberi di mescolazione ad asse orizzontale assistiti da una doppia motorizzazione. The present patent application for a utility model relates to a mixer for concrete and similar mixtures, equipped with two horizontal axis mixing shafts assisted by a double motorization.

Come è noto gli attuali mescolatori per calcestruzzo e simili sono costituiti da un’ampia vasca entro cui operano due alberi controrotanti ad asse orizzontale, sui quali sono fissate rispettive serie di bracci radiali preposti effettivamente al rimescolamento dell’impasto riversato nella vasca medesima. As is known, current mixers for concrete and the like consist of a large tank within which two counter-rotating shafts with horizontal axis operate, on which respective series of radial arms are fixed, effectively designed to mix the mixture poured into the same tank.

La tecnologia attuale prevede che ognuno di questi alberi sia innestato e sostenuto in corrispondenza di due pareti contrapposte della vasca; essendo altresì previsto che ad una delle estremità di ciascun albero sia applicato, sull’ esterno della vasca, il gruppo di motoriduzione capace di assicurare all’albero medesimo la necessaria capacità di rotazione, mentre l’estremità contrapposta dello stesso albero è supportata da un opportuno cuscinetto fissato alla rispettiva parete della vasca. Current technology provides that each of these shafts is grafted and supported in correspondence with two opposite walls of the tank; it being also provided that at one of the ends of each shaft there is applied, on the outside of the tank, the gearbox unit capable of ensuring the necessary rotation capacity to the shaft itself, while the opposite end of the same shaft is supported by a suitable bearing fixed to the respective tank wall.

Considerando peraltro la scarsa fluidità degli impasti da mescolare in tali dispositivi occorre prevedere che ciascuno di tali alberi di mescolazione sia assistito da un rispettivo motoriduttore di considerevole potenza. Considering, however, the poor fluidity of the mixtures to be mixed in such devices, it is necessary to provide that each of these mixing shafts is assisted by a respective gearmotor of considerable power.

Ebbene proprio questa particolare esigenza ha reso finora piuttosto problematica la costruzione di mescolatori di dimensioni superiori allo standard più diffuso, visto che la mescolazione di masse di impasti di ingenti volumi imporrebbe l’adozione di motoriduttori aventi potenze e dimensioni eccedenti quelle dei tipi comunemente in produzione presso le industrie specializzate. Well, this particular need has so far made the construction of mixers with dimensions higher than the most common standard rather problematic, given that the mixing of masses of doughs of large volumes would require the adoption of gearmotors with powers and dimensions exceeding those of the types commonly in production. at specialized industries.

Pertanto si può dire che, fino ad oggi, chiunque avesse voluto aumentare la capacità delle vasche dei propri mescolatori sarebbe stato costretto rivolgersi alle Aziende specializzate per chiedere la progettazione e la realizzazione di appositi motoriduttori “fuoriserie” di elevatissima potenza, con tutte le difficoltà ed i costi facilmente immaginabili. Therefore it can be said that, until now, anyone who wanted to increase the capacity of the tanks of their mixers would have been forced to contact specialized companies to ask for the design and construction of special "custom-built" gearmotors of very high power, with all the difficulties and easily imaginable costs.

Lo scopo della presente invenzione è quello di realizzare mescolatori dotati di vasche di dimensioni e volume interno nettamente superiori a quelli delle vasche dei mescolatori standard, evitando però il ricorso agli anzidetti costosissimi ed ingombranti motoriduttori “fuoriserie”. The object of the present invention is to produce mixers equipped with tanks with dimensions and internal volume significantly higher than those of the tanks of standard mixers, while avoiding the use of the aforementioned very expensive and bulky “custom-built” gearmotors.

L’idea alla base della presente invenzione è quella di prevedere il montaggio di una coppia di motoriduttori di tipo standard per ciascun albero di mescolazione adottato nella mescolatrice secondo il trovato; più precisamente ciascuno di tali motoriduttori deve essere applicato, sull’esterno della rispettiva parete della vasca, ad una delle estremità dell’albero di mescolazione. The idea behind the present invention is to provide for the assembly of a pair of standard gearmotors for each mixing shaft adopted in the mixer according to the invention; more precisely, each of these gearmotors must be applied, on the outside of the respective tank wall, to one of the ends of the mixing shaft.

In tal modo si comprende facilmente come ad un simile albero di mescolazione possa essere applicata una grande potenza, pari alla somma delle potenze dei due anzidetti motoriduttori, senza bisogno di ricorrere a componenti appositamente progettati ed evitando di stravolgere la struttura generale del mescolatore che debba adottare un simile albero con doppia motorizzazione. In this way it is easy to understand how a great power can be applied to such a mixing shaft, equal to the sum of the powers of the two aforementioned gearmotors, without the need to resort to specially designed components and avoiding upsetting the general structure of the mixer that must be adopted. a similar shaft with double motorization.

Per maggiore chiarezza esplicativa la descrizione secondo il trovato prosegue con riferimento alla tavola di disegno allegata, avente solo valore illustrativo e non certo limitativo, in cui le figure 1 , 2 e 3 sono rispettivamente la vista di fianco, dal fronte e dall’alto del mescolatore secondo il trovato. For greater clarity of explanation, the description according to the invention continues with reference to the attached drawing table, having only an illustrative and certainly not limiting value, in which figures 1, 2 and 3 are respectively the side, front and top view of the mixer according to the invention.

Con riferimento alle figure allegate il mescolatore secondo il trovato (1) si avvale usualmente di una vasca di mescolazione (2) avente in pianta una forma rettangolare e corredata di un coperchio a forma di tettuccio (3) con oblò laterali (3a); in corrispondenza delle sue pareti trasversali (4) sono innestate le estremità di due alberi di mescolazione ad asse orizzontale, paralleli e controrotanti. With reference to the attached figures, the mixer according to the invention (1) usually uses a mixing tank (2) having a rectangular shape in plan and equipped with a canopy-shaped lid (3) with side windows (3a); the ends of two parallel and counter-rotating horizontal axis mixing shafts are engaged in correspondence with its transverse walls (4).

Come anticipato, la caratteristica peculiare del trovato è quella di prevedere che ognuna delle estremità di ciascun albero sia accoppiata, sull’esterno della relativa parete portante (4) della vasca (2), con un gruppo motoriduttore (5) di dimensioni e potenza standard. As anticipated, the peculiar characteristic of the invention is that of providing that each of the ends of each shaft is coupled, on the outside of the relative bearing wall (4) of the tank (2), with a gearmotor unit (5) of standard size and power. .
