PREFERRED EMBODIMENT OF THE INVENTION

(7) The composition, characteristics and procedure of the static plant for preparing feed mixes for ruminant livestock that is the subject matter of the present invention, can be better understood in the following description, referring to a preferred embodiment shown in the attached figures.

(8) FIG. 1 shows a plan view of the invention, comprising a conveyor unit (1), comprised by a horizontal conveyor belt (3), fitted at its discharge end with a cross belt (2), intended to supply one or more mixers (9).

(9) It also shows the chain and/or screw feeders (4), intended for supplying their contents to the horizontal conveyor belt (3), in a measured manner, being located on one or both sides of the said conveyor belt.

(10) Very near to the discharge zone and positioned opposite each other, are the feeders with weight sensors (5), characteristic of the invention, which incorporate a cutting mill (6) in their discharge zone, the said feeders being positioned on either side of the horizontal conveyor belt (3) and opposite each other, being linked together by means of a supplementary conveyor belt (7), parallel to the horizontal conveyor belt (3) and positioned at a higher level, supplying the cross belt (2).

(11) Also depicted alongside the different feeders is a wheel loader to supply the contents of feeders that have a large capacity, unlike existing plants in which the feeders have a small capacity and can be loaded with hand shovels.

(12) Sideways to the conveyor unit there is also enough space for the wheel loader to discharge directly, so that in the event of one or several of the feeders breaking down, loading of all the solid ingredients can be carried out manually.

(13) The silos of liquid ingredients (8) are shown positioned very near to the mixers (9), since these silos have a piping installation (10) with flow gauge allowing direct and controlled discharge of the liquid ingredients onto the mixer (9) that is active at that moment.

(14) The silos of solid ingredients (11) are also shown, having a weighing hopper (12) to release the exact amount of ingredients onto the cross belt (2) that discharges them into the corresponding mixer (9).

(15) In FIG. 1, although two mixers (9) are shown, the static plant can be configured with more mixers (9), in anticipation of possible repairs or maintenance on one of the mixers, in order to maintain the level of productivity.

(16) The mixers (9) include weight sensors, laser sensors to measure distances and determine a level curve map to control the mix obtained, also incorporating strain gauges placed at different points on the drum to determine its deformation on the three spatial axes. The mixers (9) are positioned at a lower level in relation to the horizontal conveyor belt (3) and feeders (4 and 5), to facilitate the discharge of ingredients.

(17) The slewing discharge conveyor belt (13) of the mixers (9) is shown discharging the mix obtained onto a circuit of conveyor belts (14), envisaged for the distribution of the mix by known means.

(18) FIG. 2 shows an elevation view of the static plant for preparing feed mixes for ruminant livestock, showing the difference in level between the conveyor unit (1) and feeders (4 and 5), in relation to the mixers (9), located at a lower level.

(19) This FIG. 2 shows the guiding sides (15) of the horizontal conveyor belt (3), incorporating at its end a cross belt (2) to supply the mixers (9) with the ingredients.

(20) It also shows the supplementary conveyor belt (7) linked to the feeders with weight sensors (5), in which its raised position in relation to the conveyor unit (1) can be seen.

(21) On the lower level, the position of the mixers (9) is shown and the slewing discharge conveyor belt (13) discharging the mix onto any of the different known devices, for storage and for distribution of the mix.

(22) FIG. 3 shows a front detail of the positioning of the chain and/or screw feeders (4) at different heights in relation to the feeders with weight sensors (5), characteristic of the invention.

(23) This view shows the horizontal conveyor belt (3) with its guiding sides (15) and the raised supplementary conveyor belt (7), linked to the feeder with weight sensors (5).

(24) FIG. 4 provides an elevation view of the static plant for preparing feed mixes for ruminant livestock, showing the difference in height between the different devices that form it, showing the silos of solid ingredients (11) equipped with a hopper (12) with weight control means, to discharge the ingredients onto the cross belt (2) by means of a screw feeder (16).

(25) It also shows the silos of liquid ingredients (8) directly connected to the mixers (9) via a piping installation (10) with flow gauges to control discharges.

(26) Furthermore it depicts, on a lower level, the mixers (9) equipped with slewing discharge conveyor belts (13), showing the position of the horizontal conveyor belt (3) fitted with a cross belt (2).

(27) FIG. 5 shows a flow diagram in which the height difference of the plant can be seen and, on one side, the chain and/or screw feeders (4) and the feeders with weight sensors (5), discharging ingredients onto the supplementary conveyor belt (7), and the rest of the conventional chain and/or screw feeders, discharging ingredients onto the horizontal conveyor belt (3) of the conveyor unit (1).

(28) In addition, it shows the horizontal conveyor belt (3) linked to the cross belt (2), positioned between both mixers (9) with its slewing discharge conveyor belt (13)

(29) The silos of solid ingredients (11) are also shown schematically, discharging ingredients onto a hopper (12) so that, once weighed, they can be discharged onto the cross belt (2) via a screw feeder (16).

(30) Likewise, the silos of liquid ingredients (8) are shown connected to a piping installation (10) with flow gauge, directly connected to the mixer (9) that is active at the time that discharging takes place.
