Poikaskasvattamo

The invention relates to a hatchery, in particular for breeding poultry, comprising a breeding space connectable to heating and ventilation means and means for dividing the breeding space into two or more parts, the breeding space consisting of a relatively lightweight material such as sheet metal, plywood, fiberglass or other tunnel-like structure in which the division of the nursery space into two or more parts is adapted to be carried out by means of air-permeable partitions.

Chicks are used to raise chickens until they are large enough to begin heavy teu-15 rearing. Chickens usually spend the first four weeks of their lives in a chick farm. In the rearing of poultry, rearing structures are used in which the poultry are housed at different temperatures depending on the stage at which the rearing of the poultry 20 takes place.

It is previously known to handle the rearing of chickens in chick farm structures resembling a normal building with a large factory-like lat-25 underfloor-heated hall built on a concrete or building material-based base, in which a large number of chickens are housed. A solution as described above is known, for example, from U.S. Patent 4,224,900. DE-A-839 736 discloses a box-like two-part nursery, the other part of which is heated by warm air introduced into the nursery.

The disadvantages of such known solutions are manifold, hall-like, large buildings are energy-economically disadvantageous and also expensive to build. The hygiene of the dominant nurseries and, consequently, the mortality of 35 pups are also not at a satisfactory level.

A two-part kennel, one of which is heated by air, also does not meet the strict requirements of modern pup rearing, and a kennel such as the one described is difficult to use. Flexible handling and transfer of chicks is not possible.

It is an object of the present invention to provide a chick farm which avoids the above-mentioned disadvantages and provides a chick farm structure which allows the chick to be reared on an inexpensive, hygienic and flexible house. This object is achieved by a hatchery according to the invention, characterized in that the hatchery comprises means by which the air-permeable partitions are adapted to be movable forward along the hatchery space and that the hatchery further comprises locking means adapted to interlock the air towards the nursery farm.

The chick hatchery according to the invention is based on the idea that in a light-structured tunnel-like hatchery structure, air-permeable partitions can separate batches of chicks at different stages of rearing, whereby a kind of wind tunnel is formed when warm air is blown into the tunnel. in compartments separated by air-permeable partitions it cools down.

The different compartments of the farm may also consist of several parallel farm structures connected to a common heating and air-conditioning device. With the help of the 3 0 pups hatchery according to the invention, the rearing of the pups can be carried out in a more economical manner than before, and at the same time, thanks to the improved hygienic conditions, it is possible to achieve lower pup mortality. Managing the rearing process is also easier. With the juvenile hatchery according to the invention, the juvenile production can be kept continuous, in which case the chicks at the end of the rearing are removed from the end of the 11: 39 9 00 00 tunnel-like rearing structure and the chicks are added to the first stage of rearing. According to the applicant's observations, the chick farm according to the invention achieves, for example, a significant reduction in operating costs compared to a larger, controlled farm.

The invention will be described in more detail below with reference to the accompanying drawings, in which Figure 1 shows a schematic top view of a hatchery according to the invention, Figure 2 shows a schematic side view of a hatchery, Figure 3 schematically shows a Fig. 6 is a schematic view of a chick farm from the heating air outlet side; Fig. 7 is a schematic view of a chick farm comprising a plurality of juxtaposed rearing structures.

The nursery shown in Figures 1, 2, 5 and 6 comprises a nursery structure 1 which forms, with the exception of the base, surrounded by walls of a relatively lightweight material such as plywood, sheet metal, fiberglass, hardboard or other similar material. Thin-walled concrete casting or the like is also possible. The walls are attached to a frame structure 3, which is, for example, a tubular frame or the like. The bottom of the breeding farm 2 consists of a net bottom (not shown) through which the manure produced by the chicks can be removed from the 35 farm 2.

The tunnel-like breeding structure 1 communicates on the air inlet side A with the heating and ventilation device 4 via the supply air duct 5 and the supply air guide 6. Correspondingly, the tunnel-like breeding plant structure is connected to the heating and ventilation device 4 on the exhaust air side B via the exhaust air guide 7 and the exhaust air duct 8.

The nursery space 2 can be divided into two or more sub-areas by one or more air-permeable partitions 9, whereby dividing the nursery space 2 by partitions 9 forms successive sub-areas in the direction D of the air flowing in the nursery 2.

Below the actual breeding structure 1 there is a manure conveyor 10 comprising drive wheels 11, one or more of which are connected to an actuator (not shown) which provides a rotating movement. The manure conveyor 10 is located in its own housing 12, which is located immediately below the bottom of the nursery space 2.

In a preferred embodiment of the invention, at least brought to 20 of the air deflectors 6, 7, preferably the air inlet side of the A-side air guide 6 by kasvattamorakenteen one side end of the cross-sectional area substantially tunnel-excellent kasvattamorakenteen one cross-sectional area, the air flow C, D can be directed evenly over the entire 25 kasvattamotilaan 2.

In a preferred embodiment of the invention, the chick farm comprises means by which the amount and / or temperature of the air E flowing into the farm space 2 from outside the farm is adapted to be adjustable. By means of the means for adjusting the temperature of the replacement air E entering the breeding room 30 2 or the amount of replacement air E, it is easier to provide different temperature ranges for the breeding room 2 for the chicks at different stages. The means for adjusting the amount of replacement air E can at its simplest consist of a slightly spaced-out hatchery structure 1 and a manure conveyor housing 10 90003 of 12, thereby forming an opening 13 for the flow of replacement air E further through the plant base 1 or other air-permeable space. -wadding mode 2.

5 Replacement air E volume adjustment can also be implemented in such a way that poikaskasvattamo comprises a locking and transmission means 14, which kasvattamorakenteen 12 the distance between the one and lantakuljet-converter 10 of the housing can be changed, preferably in such a way that kasvattamorakenteen one air off 10 downside to B of kasvattamorakenteen 1 and 12, the distance between the lantakuljettimen the housing 10 can be increased more than the air inlet side A of the kasvattamorakenteen 1 and 12, the distance between the lantakuljettimen 10 of the housing, wherein the reduction temperature is increased kasvattamotilan 2-15 motilan 2 in rear parts is easier.

In a preferred embodiment of the invention, the chick farm comprises means by which one or more partitions 9 are adapted to be movable in the hatchery room 2, whereby the relocation of the chicks in the hatchery room 2 is flexible. The means adapted to move the partitions 9 comprise slide rails 15 and 16, sliding members 17 and 18 fixed to the partition wall 9, a transfer member 19 fixed to the partition wall 9 and a space 20 formed in the nursery structure 1 along which the transfer member 19 fixed to the partition wall 9 is adapted to be moved. 3 and 4).

In a preferred embodiment of the invention, the nursery comprises locking means adapted to lock the partition 9 in place at some point in the nursing space 30 2. The locking means comprise a thread 21 or a corresponding first locking piece formed on the transfer member 19 and a nut 22 or a corresponding second locking piece fitted therein.

The operating principle of the chick farm according to the invention is as follows. With the heating and ventilation device 6 ') Ο ϋ O 3 4, a sufficient temperature and air flow are generated in the wind tunnel formed by the growth structure 1. From the heating and ventilation device 4, the warm air is led through the air duct 5 to the nursery, from where the air returns to the heating and ventilation device 4 via the exhaust pipe 8, where the energy contained in the warm air is recovered, after which the air is removed from the heating and ventilation device 4. 23 and correspondingly new air is introduced into the system via the supply duct 24 of the heating and ventilation device.

A first partition 9 is placed in the breeding space 2, which is placed at a sufficient distance from the beginning of the breeding space 2 so that the chicks have enough space. The chicks are placed in the first part of the nursery space 2 formed as described above. For example, a wind tunnel can be divided into four parts, each with a different temperature. After a certain time, for example a week, a second partition 9 is placed in the nursery space 2 from the beginning of the nursery structure 1 and then the partitions 9 are first moved, the first partition between the partitions is moved forward along the nursery space 2, after which a second The chicks gather in their own part against the partition 9 at the warmer end of the partition 25, i.e. on the supply air side A. The chicks gather against the air-permeable net 25 of the partition 9, whereby the air D flowing in the tunnel and the movement-limiting partition 9 act as artificial means for the pups. With the partitions 9, the breeding space 2 can be divided into as many 30 sub-areas as are considered necessary.

The partitions 9 comprise sliding members 17 and 18, by means of which the partitions 9 can be moved along sliding rails 15 and 16 fixed to the frame 3 of the nursery or to the wall or ceiling of the nursery structure 1. The roof or wall of the farm 1 structure 1 comprises a space 20, preferably ti
