Finally, Fig. 5 is a front view, and partially sectioned, from the machine itself.

According to these drawings, the mixing and / or meat grinder machine object of this invention is constituted by a mixing bowl (1), inside which rotating mixing blades (2), fixed to a transverse horizontal axis (3) are located. ), which is connected to the drive assembly, located on one side of the tank, and formed by the reducer (4), and by way of example, a toothed crown and an electric motor (5), and the electric motor (5). The set is completed by fixed blades (2a) that complement the mixing action of the rotating blades
(2).

At the other end of the shaft (3) is a support and fixing device (6), usual and known mechanism, which allows the aforementioned shaft (3) to be released, in order to extract it very easily together with their mixing blades (2), to proceed to cleaning and maintenance.

The tank (1) is provided with a lid (7), which for its rotation or elevation it is equipped with lateral hinges (8). A latch (9) guarantees the closing of the lid (7) during process.

On the upper face of the mentioned cover (7) there is a visor (10), covered by a transparent protective plate, and a series of slits (11) for the introduction of the products that are necessary in the mixing, kneading or mixing operations. macerated, without even opening the lid (7), as well as allowing air to escape from the
process.

Finally, in the upper back of the tank (1) a folding screen (12) is placed for protection at the moment when the meat to be treated is deposited inside of said mixing bowl (1) having previously lifted the lid (7).

The repeated mixing bowl (1) is characterized for being axially tiltable, folding forward, being its tilt axis, the transverse axis itself (3); a latch of spring safety (13), keeps the tank (1) secured in the initial vertical position of work, having to withdraw the pivot of said latch when the tank (1) has to be tilted towards ahead, operation that the user will carry out manually, holding an upper lever (14) located there.

It is also essential feature of the mixing bowl (1) the special arrangement of a sliding hatch (15) that closes the mouth (16) existing at its bottom and that communicates with the lower area of chopped machine, just above a spindle
(18).

This sliding hatch (15), provided with the timely handle (15a) for its displacement, adopts two positions: the raised laterally, leaving open the passage through the mentioned mouth (16) of communication of the tank (1) with the zone of the rotary spindle (18), and lower or lower moment in which this step is closed and the mixing bowl (1) is fully closed in your entire body, being only accessible, both for filling as for emptying, through its upper mouth, filling that is done simply, lifting the lid (7), and emptying it perform having previously swung the tank (1) towards in front of.

Side guides (17) drive the trapdoor (15) while moving up or down, according to described in the previous paragraph.

The rotary spindle (18) constitutes the basic element of the machine zone to carry out the Minced meat. Said spindle (18), located horizontally, in longitudinal direction, under the mixing bowl (1) figure installed inside the chopped body (19) integral with the mechanism of drive located at the rear of the machine and preferably constituted by a gear reducer (20) and the electric drive motor (21).

The front part of the chopped body (19) ends in a front outlet (22), covered by a protective housing (23), which prevents accidental access to that outlet and, consequently, any possible accident to user. This housing (23), is rotatable on a lower axis (24), so that when it turns it allows access to the mouth of output (22) of that zone of action of the rotating spindle (18), being provided in addition to a suitable microswitch that stops automatically spindle movement (18) at the moment the housing (23) has moved, all for the purpose of its cleanliness and safety

The movement transmitted by the group gearmotor (20/21) to the spindle (18) can be reversed in certain occasions, when there is a jam in the process of minced meat, usually by the presence of some splinter of bone or other similar impurities. Spindle rotation (18) in the opposite direction facilitates the unblocking of the area of chopped.

In turn, the movement transmitted by the group gearmotor (4/5) to the shaft (3) of the blades (2) is, in certain moments of the work cycle, in the direction of the needles of the clock, and at other times, counterclockwise.

Thus, in the first operation of the cycle, the mixed, the blades (2) rotate counterclockwise clock, the spindle (18) remaining stationary.

During the emptying of the tank (1) through its mouth lower (16) of passage towards the spindle (18), in the body of chopped (19), the blades (2) rotate in the opposite direction to the needles of the clock while the spindle (18) works in the normal sense progressive.

During the kneading of the meat, carried out in the tank (1) with its lower flap (15) closed and therefore isolated of the chopped body (19), the blades (2) rotate in the direction of the clock hands This kneading is an operation after chopped, which should be done according to what cases, for which the minced meat already poured outside through the front outlet (22) and collected in a suitable container (not shown), is poured back into the tank (1), proceeding to kneading saying, operation in which the meat is pressed against the tank walls (1), causing the elimination of any air bubble that could be inside the mass, air which, in turn, goes outwards through the slots (11) of the cover (7) slots through which they have been inserted, conveniently, the usual complementary products, such as species and similar, during this kneading process.

It is precisely this possibility described that owns the machine and that allows you to carry out this operation of kneaded that gives the characteristic of its operability alternative.

This kneading operation is finished, and also of macerated and when the tank (1) has tilted, collapsing towards in front to proceed to its emptying, the blades (2) turn in direction counter clockwise.

The machine also presents, along with its necessary control panel (26), preferably two push buttons (27), for the safety drive of the blades (2) of the inside the mixing bowl (1) when it has been tilted and It is emptied.

This operation is carried out advantageously and without manual intervention by the action of the blades themselves (2) turning counterclockwise, being essential, for obvious safety reasons, that the movement of said blades is carried out only when preferably the two push-buttons (27) are operated in unison by the user, avoiding that you can insert one of your hands inside the tank (1), with the blades (2) running, which could cause a serious accident

Always within the safety regulations, together with the set of the two buttons (27) for actuating the blades (2) for the emptying of the tank (1) lowered towards ahead, there will be the necessary microswitches for protection, as previously indicated, of all those elements mobile or scrollable that the machine has, as well as the timers needed to program the times of the Different operational phases to carry out.

The machine is completed, object of this invention, with the side frames (28) on which are left fixed the transverse axis (3), together with the mixing bowl itself (1) and gearmotor assembly (4/5), and protective fairings (29) on the side area of the machine, covering the assembly gearmotor (4/5), and the fairing (30) that covers the front of the chopped area and the gearmotor (20/21) and the fairing (31) which covers the back of said gearmotor.

The whole machine is arranged on a suitable frame or foot (32), whose height is related to the of the product withdrawal tanks.

Described sufficiently the object of the In the present invention, it should be noted that any variation in the dimensions, exterior shapes, finish, types of materials employees, as well as the known mechanisms that make up the set of the machine, nothing will alter the essentiality of the same, being summarized in the claims that follow.
