2. Description of the Related Art A large-scale poultry raising facility in which a large number of chickens are housed in cages that are stacked in a plurality of rows and partitioned in long rows, and the cage rows are arranged back to back, Maintaining cleanliness and ensuring chicken health under good hygiene is a vital issue for poultry farmers. In particular, when breeding chickens are housed in cages, by contaminating the breeding eggs (eggs for hatching chicks) with miscellaneous bacteria in the feces, it is easy to cause a decrease in hatchability and chick quality. is necessary. Therefore, in this type of large-scale poultry house, a belt conveyor for receiving chicken droppings is provided below each cage row, and the droppings are dropped on it. I try to make it easy to scrape off. However, since the chicken dung is not sufficiently dried, the belt conveyor is operated while the chicken dung is adhered to the belt, which is not hygienic.

In order to effect this drying effectively, for example, the midline along the longitudinal direction of two cage rows arranged back-to-back, below the highest part of the cage grid floor, above the belt conveyor. Many dryers have been proposed in which air ducts for drying and drying chicken dung are provided in the longitudinal direction in a space, and air is forced to be blown by supplying air to both sides to dry chicken dung. By the way, when breeding chickens in a cage, they are usually mixed and bred at a ratio of 10 females to 1 male, but males tend to gather near the highest part of the cage lattice floor. So this part is
Chickens tend to be denser and more dry is excreted. On the other hand, in a cage for breeding chickens, males are likely to gather in this portion because there is no partition member for partitioning the cage rows between two cage rows that are generally arranged back to back.

Since the above-mentioned air duct for dry air blow is provided in the space above the belt conveyor in contact with the lower part of the lattice floor of this part, it has a drawback that it is easily polluted by chicken droppings dropped or accumulated on the belt conveyor. there were. Since the lattice floor is also an inclined surface for spawning collection, if the air tube near the lattice floor is polluted, the seed eggs are likely to be contaminated with various bacteria, and the hatchability and chick quality of the seed eggs are likely to deteriorate. there were. In addition, since the air tube is installed near the top of the lattice floor, the scaffolding is bad and unstable for males gathering there, leading to a decrease in the fertilization rate of females, and thus a decrease in the fertilized egg rate, and chick productivity. There was also a drawback that

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention The chicken droppings drying apparatus according to the present invention solves the above-mentioned problems of the conventional chicken droppings drying apparatus in which various hygiene drawbacks are found especially in the case of breeding cages. The purpose of the present invention is to provide an apparatus capable of efficiently drying, which prevents contamination of the eggs and helps improve chick productivity.

[0006]

[Means for Solving the Problems] In order to achieve this object, a poultry drier drying apparatus for a poultry house according to the present invention has a plurality of cage rows partitioned back to back to accommodate an appropriate number of chickens in each compartment. Stacked, below the cage row,
In a poultry manure drying device of a poultry house having a belt conveyor for receiving poultry manure that extends in the longitudinal direction and moves in the longitudinal direction, an air tube for drying poultry manure is attached along the longitudinal direction below an egg collection tray located in the front of the cage. , From the air tube,
A large number of air supply branch pipes for supplying air for promoting chicken dung drying onto the belt conveyor are characterized in that the air pipes for blowing air communicate with the space above the belt conveyor. If this cage is especially a cage for breeders,
It is characterized in that there is no partition member for partitioning the cage rows between the cage rows arranged back to back.

[0007]

As described above, the chicken manure drying apparatus according to the present invention is provided with the air pipe for drying chicken manure, which is attached along the longitudinal direction below the egg collecting tray located in the front of the cage. Since the upper space is communicated with a large number of air supply branch pipes, the air flowing in the blower air pipe is directly sent to the space on the belt conveyor by the air supply branch pipes to perform an operation of drying chicken droppings.

[0008]

EXAMPLE In one embodiment of the chicken droppings drying apparatus according to the present invention shown in FIG. 1, long cage rows 1 for breeding chickens are stacked in three stages, and these rows are arranged back to back. As can be seen from Fig. 2, there is no partition member for partitioning the cage rows 1 and 1 from each other so that the cage rows 1 and 1 can be freely moved. Below the cages in each stage, a belt conveyor 2 for transferring chicken droppings 2'falling from the cages in the direction of the arrow is provided over the entire length of the cage row. The bottom of the cage is
Poultry manure passes through this to reach the belt conveyor 2, and is composed of a lattice floor 3 which is also an inclined surface for collecting eggs, and a bait gutter 4 is attached to the front surface. A water supply pipe 5 is provided above the front of each back-to-back cage row 1, and a water receiver 6 is provided below the water supply pipe 5.
Is provided.

In the space corresponding to the partition between the two cage rows, that is, the space 7 just below the highest portion 3'of the lattice floor 3, the chicken cage dry air blower is provided in the conventional cage. However, in the cage of the poultry house according to the present invention, since there is no air duct for blowing in this space 7, males are likely to gather, and most of the chicken dung 2'is deposited on the belt conveyor 2 located below it. It's easy to do. On the front side of the cage row 1, an egg collecting tray 8 formed at the end of the lattice floor (collecting inclined surface for egg laying) 3 is arranged along the longitudinal direction, and below the chicken collecting manure, which also extends along the longitudinal direction. An air pipe 9 for dry air blowing is attached to a support member 10 provided on the front surface of the cage. An air supply branch pipe 11 made of, for example, rubber or flexible plastic is branched from the air pipe 9 for blowing air at intervals of 10 to 20 cm and reaches the vicinity of the edge of the belt conveyor 2.

The air supply branch pipe 11 communicates with the air pipe 9 for blowing air and the space above the belt conveyor 2, for example, as shown in FIG.
Mounted as you see in. The plate 12 surrounding the side of the belt conveyor 2 is provided with an air supply branch pipe 11 along the longitudinal direction.
A large number of brackets 13 for fixing the brackets are attached by screws 14, and in the example of FIG.
It is inserted in the upper space (the air supply branch pipe 11 is only slightly inserted so as not to be polluted by chicken manure). As a result, the air flowing in the air duct 9 for blowing air is sent to the space on the belt conveyor 2 through the respective air supply branch pipes 11, and the chicken dung 2'accumulated there is dried from both sides. FIG. 3 is a schematic cross-sectional view of a poultry house provided with the chicken droppings drying device according to the present invention. In this figure, a positive pressure poultry house is shown as an example, but the same applies to a negative pressure poultry house.

[0011]

The chicken droppings drying apparatus for a poultry house according to the present invention does not have the air duct for ventilation which is provided in the space 7 above the belt conveyor 2 below the top 3'of the lattice floor 3 in the conventional cage. Therefore, the following remarkable effects were able to be exhibited. (1) In the case of the cage for breeding chickens, males tend to gather near the top 3'of the lattice floor, so that the air pipes are not polluted by a large amount of chicken manure accumulated in the space 7 below it, and thus the germs of the breeding eggs are eliminated. It was possible to improve the hatching rate and the quality of chicks by eliminating the pollution caused by the. (2) The scaffolding of males, which is easy to gather near the top 3'of the lattice floor, is improved, the fertilization rate of females is increased, and thus the fertilized egg rate is also increased, which can improve the productivity of chicks.
