DESCRIPTION:
BRIEF SUMMARY
The invention relates to a coop arrangement according to the preamble of the main claim.
Coop arrangements of this type are in widespread use. A droppings conveyor belt driven and guided along an endless path is located beneath each of the superimposed rows of coops and receives the droppings on its working run, i.e., the upper run, discharges the same externally of the rows of coops and is then deflected so that the return run is conveyed back into the coop below the working run.
This known arrangement has the drawback that space is required within the confines of the superimposed rows of coops for the return of the lower run. The West German Offenlegungsschrift 34 46 665 clearly illustrates that a substantial amount of space is here necessary to insure a satisfactory return of the return run.
Should the working run be damaged, droppings fall through the supporting rolls onto the upper side of the return run. This can result in accumulations on the deflecting rolls. These accumulations on the deflecting rolls can cause the deflecting rolls to increase in diameter, although not uniformly over the entire length of the deflecting roll so that the precision of movement of the belt is significantly affected. If the belt does not travel accurately in its guide, the belt and belt guides are further damaged so that these faults are additive.
The return run travels through the rows of coops with its "dropping side" facing down. If the scraper has here not operated properly, droppings adhering to the return run can fall onto the animals in the row of coops below.
Since the watering nipples in the individual rows of coops are never one hundred percent leakproof, it is not possible to prevent water, which again accumulates at the deflecting and working rolls, from collecting between the working run and return run of the known arrangement. This also results in a poor operating efficiency and further contamination of the belt by caked dust and the like.
It is an object of the invention to design the return path of the return run in such a manner that, for a given height of the overall coop arrangement, the space within the individual coops is increased, that is, more free space becomes available above the animals, and that the drive for the droppings conveyor belts can be constructed with fewer problems
This object of the invention is achieved by the teaching of the main claim.
An advantageous embodiment is set forth in the subclaim 2.
In other words, the invention proposes that the return paths of the respective return runs of the superimposed droppings conveyor belts not be disposed within the rows of coops but, instead, that the return runs be combined either above or below the rows of coops and then again be conveyed to the inlet side of the coop arrangement. The droppings conveyor belts thus encircle the entire coop arrangement.
In this manner, the space which was heretofore required for the return path of the return run can, within each individual coop, be made available to the animals. Thus, the increased headroom required in the coops by EG regulations can ge assured without increasing the height of the overall arrangement.
In the event of damage to the droppings conveyor belt, the droppings no longer fall on the return run but, rather, on the droppings conveyor belt below so that the droppings can no longer cause accumulations in the region of the deflecting and drive rolls. Water which drips onto the belts from the watering devices can be dried by the drying air in the stall since the drying air can now pass through the large volume of the coops and the water cannot, as previously, collect in the relatively small space between the working run and return run.
The U.S. Pat. No. 3,385,266 discloses a coop arrangement for poultry farms in which a droppings conveyor belt is arranged below the row of coops. Furthermore, a channel for the guidance of drying air is provided beneath the droppings conveyor belt and the drying air is sucked out of the interior of the stall and conveyed over the droppings via an exhaust
