An outlet closed by a shut-off device is also arranged by dot.i, a return line with a corresponding gradient sum! The line pressure at the outlets is practical when feeding by di ^; Cows dos line outlet in the overflow tank b-3otir.ir.it. "Jährend feeding wirrt the Aitterbrei aua the Kischb he ehält means of the pump into the conveying line pumped and the outlets to the Preßplr.it ζ en .nacheinander be opened for each boat before inta th periods, so that a predetermined .Puttermenge is dispensed. In order to achieve a correct dosage, more feed mash was pumped into the porder line than is actually delivered, so that part of the feed mash fed into the overflow container and through the return line into the I-Ii ac Kb it flows back A thin fodder brsi is fed, as otherwise there is a risk that residues will settle in the overflow tank and in the return line, which prevent the proper feed backflow to the elevated tank, whereby it must be taken into account that the excess jutter mash can only reach the return line below the The gradient between the overflow tank and the mixing tank flows through The feed pump is briefly switched to return flow in order to remove at least some of the nut residues from the feed line. Then a flushing liquid is pumped into the delivery line from the elevated tank while the Puape is working in the normal direction of rotation again, i.e. it is conveying into the delivery line, which exits in the overflow tank and returns to the mixing tank via the return line. During this flushing process, the outlets are opened briefly in order to also flush the outlets themselves. iJacu or ~

the lines are emptied again after flushing and the rinsing liquid is drained from the mixing tank. The flushing process essentially takes place depressurized, i.e. only below the low level determined by the height of the overflow vessel above the mixing container Pressure. '

• As mentioned, the system described is known only suitable for a certain low-viscosity putter. But the whole point of a hate-feeding system is that To prepare feed for certain animal species together, being the main component of the putt he's a. Putter should be used seasonally or is particularly inexpensive due to the market. During the warm season, for example See weeping green fodder as the main component of the putter Find use where the putter composition is accurate to be based on the needs of the animals. at a known hate feeding system for pigs, a stationary mixing container is provided, in the from above the suction pipe of the feed pump protrudes, which in this version cannot be switched in its direction of rotation. Itn stall or the like. itself connects to the rest of the stationary installed line to a flexible hose, with the help of which the fed hate food directly into the Putter troughs or the like. is directed. Hach the feeding must the line, in which feed residues in normal cases increased temperatures and a large-scale air attack are exposed, so that they could spoil in the time between two feedings, too what purpose in the known system in the Ilisch container Water is introduced and conveyed through the line with the aid of the pump. This rinsing water with the feed residues is discharged into the slurry drain in the stable. i4s is therefore both for putter preparation and for flushing the system in the area of the liiscli container door

Water pipe connection necessary. The introduction of the rinse water into the slurry drain leads to an undesirable Dilution of the liquid manure and, as a result, a considerable odor nuisance in the stable the liquid manure is stirred up by the water jet and the rinsed out feed residues get into the liquid manure drain, where they still have a slow drainage or if there is a possibility that they will get stuck go into putrefaction inside the stable

In a wet feeding system of the type mentioned, the invention consists in that a single connecting the fish tank Q ± t to the feeding place (s), preferably freely laid line is provided, wherein their stalls or feeding area-side end during the Cleaning period when simultaneously switched to return Pump with a reservoir or the like. connected for water.

A system according to the invention has an extremely high Simple construction · The line and pump are flushed when the direction of flow is reversed to that of the feed ρ where the spill water is practically in every stable V / ae pipe connection necessary because of the watering of the animals can be taken. A predetermined amount of water is preferably used for rinsing, the. corresponds exactly to the amount of water used in the next feeding in the mixing tank must be added to the feed for processing, so that the rinse water used at the next feeding. Those removed from the pipe or hose line and the pump during flushing Residues of the feed also get into the mixing container with the rinsing water; since they are up there stay in the water for the next feeding and therefore are hardly exposed to air, there is no risk of them becoming inedible until the next time they are fed.

The necessary switching of the pump direction can be done either by. Reversing the direction of rotation of a pump delivering in opposite directions in both directions of rotation as well as free use of a pump delivering only in one direction of rotation can be achieved by multi-way valves or the like, the suction and pressure side of the pump in one position with the Mixing tank and the Terlinden line leading into the stable, swap these connections in the other position. " The pump can be a known eccentric screw pump which is self-priming in both delivery directions and which is suitable for very viscous media, so that the solid-liquid ratio in the Haßfatter is about 1: 2.5 compared to "at best 1: 4" 5 can be reduced in known systems. After the end of the backwashing, the line can be practically sucked empty ^: the Leitimg between the pump and the like and branched off in the stable as to sich'hekännt, from the conduit a plurality of closable by separate Ahsperrorgane outlets, n outlets / by edm there obturator closed and the outlets conduit containing part via a detachable line connection; of. a water pipe with standing water under pressure, which after closing ei it shut-off organs in the previously emptied of liquid: compresses the air contained in the line between this shut-off element and the outlets. _f which "air cushion after Abitennen der aur Wass: er ± tuitg: leading line connection - OYes opening the outlets - the ¹ previously routed water with a bridge through the outlets * -

The winding of the majority of the existing Line syatemes are made with hiire of the pump, with water again supplied from a storage container from the line and the line after consumption of this Water supply, which is in the mixing tank for the treatment # 08 putters are used the next time they are fed, can be sucked empty so that it is filled with air. During this rinsing process, however, there are which branch off in the outlets from the line have not accumulated, or only partially removed. It would be much too cumbersome during the backwashing process to go from outlet to outlet, a portable one with water hold the filled vessel over the outlet and open the shut-off device so that the outlet can be rewound is cleaned · The execution according to the invention is made possible now a perfect cleaning of the drains. laugh the The backwashing process described, the shut-off device blocking the main line is closed and it remains all shut-off devices at the outlets are initially closed · The part of the line separated by the shut-off device is at least in the area of the main line Filled with air · If you now lead this line of piping from the water pipeline, water that is under pipeline pressure closed, then this water presses when the line is laid horizontally or against the line dividing the line The shut-off element rises «the air initially contained in the main line bundle together to form an air cushion. The between the main shut-off device and the first outlet line part is dimensioned long enough - possibly also via an entry of the butter slurry at the feeding company preventive check valve connected to an air tank - so in this part of the line at normal Water line pressure to accommodate all of the compressed air.

In the drawing is a feeding system according to the invention in a schematically simplified representation. for example illustrated.

_: At a suitable place outside of a stable 1 a "mixing container 2 is set up, in which, like a mixer, stirring or knife blades 4 are attached which can be driven by a standing shaft 3. It is assumed that the shaft 3 is driven by a motor (not shown). ***" a V-belt 5. In the container 2, various feedstuffs, for example green fodder, concentrated feed, minerals and medicaments, can be mixed with a certain amount of water and, if necessary, crushed so that a pumpable pulp is produced

■ the deepest one, possibly provided with a shut-off device Place of the container 2-connects a line 6, which with connected to one connection 7 of an eccentric screw pump 8, its second connection 9 has one in the stable 1

309816/0831

leading line 10 is in connection. To drive the eccentric screw pump B , an electric motor 11 is provided, which can now be switched on and in its direction of rotation via a switch 12.

The line 10 first leads to a shut-off device 13 in the stable and then continues in a line 14. From the line 14 each branch with a shut-off device 15 equipped outlets 16 from the stationary over feeding trough eh 17 or the like. are arranged. At the end of the line 14 there is a three-way cock 18 in the exemplary embodiment, who has three working positions and in one working position completes the line end 14a that terminates at it, in a further working position this line end 14a open with one in the bottom area of a storage container 19- ^ the line 20 and, in a third working position, the Leitttiigsende 14a connects to a water line 21; Of the Container 19 can from the water line 21 from up to one by the float 22 of a Schwitninerventiles before determinable High and therefore with a predetermined amount of water to be filled;

At the beginning of a feeding, the container 2 is filled with a hitter pulp. The shut-off device 13 is open the shut-off device 10 closes the line 14a * The llbtor 11 is turned via the switch 12 in that direction of rotation switched on, in which the pump 8 from the line 6 üM thus sucks from the container 2 and into the line 1Ö promotes. As a result, the feed pulp is fed into the line 14 promoted and can be discharged via the outlets 16 into the puttering troughs 17 by opening the relevant shut-off element © 15 will*

As soon as the food supply is consumed, the shut-off devices 15 are closed and the Dreiwegehü Ϊ8 -an the place of which a corresponding slide could also be provided - is brought into that working position in which he connects the line 20 with the line 14i With the help

309816/0831

of the switch 12, the direction of rotation of the motor and thus the direction of rotation of the conveyor pump 8 is switched over, so that the pump 8 sucks the water supply from the container 19 through the line 20, 14 and 10 and conveys into the mixing container 2 via the line 6. When using a self-priming pump the lines 10, 14, 20 are sucked empty from the container 19 after the water supply has been used up, so that they are filled with air.

Then the shut-off element 13 is closed, so that it separates the line 14 from the line 10. The three-way valve 18 is brought into that position in the erAie water line 21 directly to the end of the line 14a connects. Due to the line pressure of the water supplied thereby, the pressure in the line 14 becomes Air is compressed and forms between the shut-off, organ 13 and the nearest outlet 16 an air cushion. The length of the line part between the shut-off element and the first outlet 16 is dimensioned sufficiently large to to ensure that with the occurring water pipe pressure this air cushion does not extend beyond the outlets. ffun the shut-off devices 15 are simultaneously or starting with the shut-off device 13 in the course of Line 14 on the next shut-off device 15 opened briefly one after the other. The The three-way valve 18 is brought into its position which closes the line end 14a. Under the pressure of the air cushion v / ird the water in the line 14 is sprayed out through the outlet e_ 16, the shut-off devices 15 and the Outlets 16 and the associated line parts branching off from line 14 are flushed through and thus of tutter residues getting cleaned. As soon as at the outlet lying closest to the three-way valve 18 in the course of the line 14 16 with the shut-off element 15 open, no more exit takes place, .are the line used to guide the putter
