Description
Plant for the Preparation of Fodder.
The invention relates to a plant for the preparation of fodder compris-ing a portion of solid foodstock in the form of grains or kernels, particularly corn, and a portion of water, said plant including a silo for the solid food-stock, a device for removing solid foodstock from the silo, a conveying device for conveying the solid foodstock removed from the silo to a crushing mill, and a mixing vessel for the mixing of the crushed solid foodstock and the water.
In the preparation of pig food, which comprises a subs$antial propor-tion of corn, so far, the practice has been to brlng the corn portion into an agitator vessel in which is already contained a predetermined quantity of water.
After the agitator or stirring means has been set in motion the corn portion and the water are mixed and can then be transported through a known distributing de-vice to the feeding location.
The feeding in of corn into a mixing vessel is difficult, if only for the reason that this solid foodstock is of sticky consistency; it has to be con-sidered in this connection that the solids portions are not only corn kernels but also rests of corncob stems. Therefore, it has become usual to mount a mill on the top of the mixing vessel and to charge said mill with the solid foodstock.
In this way the mill is in a position to crush the material fed thereto and directly deliver it to the mixing vessel.
In the meantime, it has also been proposed to perform the crushing operation while adding water to the material being crushed. This has the advant-age tilat the energy required for the crushing process can be reduced, but special provisions must be made to ensure that the eventually obtained preparecl fodder will contain the corn portion and water in the proper mixing ratio.
~ or the solicl foodstock portion, particularly for corn-containing pig ~Foocl, the corn, after thc harvest, is introduced iiltO silos and stored therein W.28~59/82 Me ,f~.~
- ~ -under airtight conditions. Now, in order to permit removal of said material from the silo, there is provided e.g. a milling cutter at the bottom of the silo whereby the corn material milled off is transported to the outside by a conveyor chain. However, such a device is not satisfactory, if only for the reason that due to the mode of transportation of the milled off material it is not possible to prevent air from getting into the silo. This causes decomposition processes in the stored material.
Therefore, it has become usual to attach a worm to the outlet end of the milling cutter, the worm housing being connected to the housing of the mill-ing cutter by an airtight joint. The worm will now convey the milled off anddislodged material outwardly and, preferably, the material while being conveyed will also be compressed so that no oxygen can get into the silo. Only the for-wardmost portion of the material being brought out in this way will be exposed to oxygen, and the undesirable decomposition processes will take place only in a relatively thin layer at that surface. However, that method is disadvantage-ous in that relatively high amounts of energy are required for conveying and com-pressing the solid foodstock and in that moreover, the compressed material must subsequently be milled or crushed, with further application of energy. Also, it is inconvenient that not only the silo bin but also the worm with its housing and the mixing vessel and the crushing mill must be in a specific spatial rela-tionship with one another in order that the material being removed from the silo can be conveyed through the mill into the mixing vessel.
The problem underlyi.ng the invention now is to so develop a plant of the type indicated hereinbe.Eore that in the preparation of fodder as little ollergy as possible w;.ll be needed but, on the other hand, -Eine milling of the f`odder, part:icularly mixtures of corn kernels and corncob stem parts (CCM) will bo possiblo. Also, t:he respective plant shall be so desi.gned that the spatial 3~
relationship or association of the individual parts of the plant will not be critical; particularly, it shall be possible to take foodstock out of several silo bins and to prepare fodder in one and the same mixing vessel.
The invention is characterized by the fact that a siphon is mounted be-tween the conveying device and the crushing mill, said siphon being provided with water supply conduits at the inlet and outlet sides thereof.
Tile siphon preferably located at the silo permits a satisfactory seal-ing of the material contained in the silo from the atmosphere, for, due to the siphon belng filled with water it is impossible for gas to get into the silo from the outside. On the other hand, any material removed from the silo is passed through the siphon and thereby some of the water in the siphon will neces-sarily be entrained, so that, according to the invention, water supply conduits are provided for both sides of the siphon.
If water would be supplied only at the outlet side of the siphon, mate-rial taken out of the silo could not be conveyed therethrough. If, on the other hand, water would be supplied only on the other side of the siphon, the transpor-tation of the material would be improved, but it might happen that water flows back too far into the silo, which would not be harmful but would be to no pur-pose.
According to the invention, the water inflows for the siphon are con-trolled through valves so that water can be supplied to the inlet and outlet sides of the siphon through a given program in dependence on certain operating parameters ~e.g. the current consumption of the motor for the crushing mill).
'I'i-eorctically, it would ba possible to take the amount of water fed into the slp}lon directly Erom the watcr supply, but then it would be necessary to take steps to ensure tilat the Einally produced Eodder will have the desired composi-tlon oE solid Eoodstock and water. Therefore, according to the invention, it is X
- ~ -considered expedient to introduce a predetermined fixed amount of water into the mixing vessel prior to the preparation process. Thereafter, the supply of water is terminated and the water required in the plant according to the invention is taken from the mixing vessel and conducted to the inlet and outlet sides of the siphon. The supplied amounts of water are not critical; they cannot impair the fixed mixture ratio since the preparation process is terminated when a suffi-cient amo~m-t of solid foodstock has been removed from the silo, that means the amount that is in the desired proportion to the initially given amount of water.
It is significant that by this method it is possible to positively maintain the predetermined mixing proportion, and the quantity being conveyed per unit of time can be adjusted as desired through the supply of water to the inlet side or outlet side of the siphon.
According to the invention any conveying device may be provided in the bottom or base portion of the siphon to convey the solid foodstock located there-in from one side of the siphon to the other. A number of devices are conceiv-able here; for example, there might also be used a worm. In the preparation or processing of grain, for example, a conveying device might possibly be dispensed with.
In the preparation of corn fodder (CCM), a plate or tray having webs or ribs thereon is a suitable conveying device, so that by rotating the plate or tray the solid foodstock can be conveyed from one side of the siphon to the other. ~ith the construction chosen according to the invention the drive shaft for the plate or tray is supported outside the siphon and the driving means for said shaft is also located outside the siphon. In this way, difficult mounting and sealing problems are avoided. According to the invention, the speed of the tray or plate may be preset as a fixed spet3d, for the rate of transportation of solid oodstock shall not be regulated by way oE the speed of the plate or tray as according to the invention it shall be the amount of water supplied to the siphon that shall be responsible for this.
The invention may be realized in connection with a well-known Harvestore bottom-discharge milling cutter but, in accordance with the invention, there may also be used other means for conveying and carrying ~ff solid food-stock. Thus, according to the invention, nozzles may be installed in the silo in the lower part thereof, the water jets of said nozzles being effective to dis-lodge material from the silo. This material then falls into the lower zone of the silo, especially when, after a certain period of time, the supply of water to the nozzles is disconnected. Then, further nozzles can be put in action whereby the material which has collected in the lower zone of the silo is con-veyed in the direction towards the siphon. The water used for the nozzles may also be branched off from the mixing vessel and brought to the required pressure by pumps. Altogether, in connection with the water conservation in the plant according to the invention, it has to be stated that for a predetermined quan-tity of fodder to be prepared sufficient water is available for the reason that said water can circulate while it is ensured all the same that the water content of the fodder produced will not be too high.
The invention may also be used in connection with a discharging device provided at the lower end of a Harvestore bin and substantially comprising a spindle driven by means of a motor. Wound on said spindle is a chain the radial length of which is greater or less depending on the axial position. As the spindle is rotated, the chain revolving therewith can knock off, loosen and de-tach the material stored in the silo so that this material will fall into the collccting vesseL below or get into the conveying means through the siphon to the mill.
I:urtller embodiments of the invention may be learnt from the various clainns.

The invention will now be explained by way of example by reference to the drawings wherein Fig. 1 shows a diagrammatic representation, not to scale, of a plant in accordance with the invention, and Fig. 2 shows a diagrammatic representation, also not to scale, of a modified embodiment according to the invention.
In Fig. 1, 10 designates a silo or storage bin having a conveying de-vice 11 thereon. Directly following said conveying device is provided a siphon 12, said siphon being sealedly connected to said conveying device 11. Provided on the outlet side of the siphon is a conduit 13 which leads to a crushing mill 14. From said crushing mill 1~, the crushed material, together with more or less water, is conducted through a conduit 15 to the mixing vessel 16. The mix-ing vessel 16 is further provided with a water-supply pipe 17.
It is significant that the conduit 13 as well as the conduit 15 may be of any form. It is not necessary to adhere to straight-line connections between the individual parts or components; ~hus, for example, the conduit 15 might be two or also twenty meters long, which is not critical in regard to the transpor-tation because, here, crushed material is transported in water.
The siphon 12 illustrated in Fig. 1 shows a substantially square block-like structure with a partition 20 in the middle thereof which, however, doesnot extend down to the bottom of the siphon. In the base or bottom portion of the siphon there is located a tray or plate 22 having a plurality of radially extending webs or ribs 23 thereon. The tray or plate is connected to a drive shaft 21 which is supported outside the siphon and is also driven outside the siphon as is indicated by an arrow. A specific water level is adjusted in the siphon, as is inclicated by the two triangles.
A concluit 24 extends from the mixing vessel 16 to a change-over valve 25 which is capable of connecting the conduit 2~ either to a conduit 26 or to a conduit 27. The two conduits 26 and 27 may of course also be separately con-nected to the mixing vessel 16 by separate conduits, further shutoff valves being provided for each of said conduits.
Before the preparation apparatus proper is put into operation, a spe-cific amount of water is introduced into the mixing vessel 16. From there, water is admitted to the siphon, through the conduit 24, either to one or the other side of the siphon. Finally, the conveying device 11 is pu-t in motion so that material gets into the left side of the siphon 12, said material being con-veyed from the left side to the right side of the siphon by the rotating plateor tray 22. Depending on the amount of water supplied through the conduit 27, more or less solid material is carried to the right side of the siphon and finally gets through the conduit 13 into the crushing mill. From there, the crushed material, together with water, is conducted through the conduit 15 into the mixing vessel. In the mixing vessel, the material carried into the latter separates from the water, and water can be transferred, in the desired amount, into the siphon via the conduit 2~. Only after a sufficient amount of solid foodstock has been introduced into the mixing vessel 16 will the further trans-portation be stopped and the mixing device ~not shown) in the mixing tank 16 be put in motion.
Fig. 2 shows a modified conveying device according to the invention.
This conveying device comprises substantially a cylindrical conduit 36 which has one end thereof sealedly connected to the siphon 12 and the other end sealedly comlected to the bottom of the silo lO. Nozzles 30 and 31 are located at the lower end of the silo or -the lower end of said conduit. Only two nozzles are shown, but there may of course be provided a plurality of nozzles and -there may aLso be used movahle nozzles, e.g. wobble nozzles, so that when the nozzles 30 and 31 are put in motion by supplying water through the shown conduits 33 and 34, material is removed from the foodstock 37 contained in the silo 10 in a more or less conical region. When the supply of water to the nozzles 30 and 31 is dis-continued, the dislodged material can collect at the lower region of the silo 10 or at the beginning of the conduit 36. ~ow, a nozzle 32 is supplied with water ~ulder pressure through a conduit 35, so that the collected material can be con-veyed into t.he siphon.
The conveying device shown in Fig. 2 has been described in broad out-line only. Any kind of nozzles or nozzle forms may be used and it is also con-templated to provide for a pulsed pressurization of the water so as to achievean optimum dislodging effect. In any case, the nozzles 30 and 31 on the one hand and the nozzles 32 on the other hand must be operated alternately, which, however, can easily be controlled by a preset program.
