In recent years, the outbreak of bird flu has frequently restricted the movement of food birds. As a result, the poultry processing plant that the poultry farm used to transfer live birds to is included in the restricted movement area, and the poultry processing plant outside the restricted movement area that did not previously transfer live birds eats. The situation where the bird transfer destination is suddenly changed has come to occur. If the unlocking mechanism of the bird processing factory that was the destination of the transfer is different from the unlocking mechanism of the conventional bird processing factory of the transfer destination, the lock cannot be unlocked at the bird processing factory that was transferred, and the discharge door. Will be impossible to open. If there is no poultry processing factory in the vicinity that has the same unlocking mechanism as the conventional poultry processing factory, there are many distant poultry processing factories that have the same unlocking mechanism as the conventional poultry processing factory. There is a problem that it becomes necessary to transfer the feeding birds by spending the transfer energy of the raw birds, or it becomes impossible to transfer the live birds to the feeding bird processing factory. If the transfer of live birds becomes impossible, the breeding period at the poultry farm will be extended, and the energy required for breeding will increase.
The present invention has been made in view of the above problems, and is a live bird transfer cage for transferring live birds from a poultry farm to a poultry processing factory, and includes a main body for accommodating live birds and a part of the side wall of the main body.

If the live bird transfer cage module A is equipped with a second locking mechanism and the poultry processing plant is equipped with a unlocking mechanism for the second locking mechanism attached to the tilting mechanism, the unlocking mechanism of the poultry processing plant is used. Insert it into the live bird transfer cage 1 through the gap between the channel steel 12a and the upper edge of the discharge door 5, engage it with the upper edge of the discharge door 5, and pull the upper edge outward to form a groove. The claw 14a of the cross-section rubber 14 is elastically deformed outward, and the upper edge portion of the discharge door 5 is separated from the groove-shaped cross-section rubber 14. As a result, the discharge door 5 swings and opens as shown in FIG.
Next, the live bird transfer cage module A is tilted so that the discharge door 5 is directed diagonally downward by using the tilting mechanism provided in the bird processing factory.
The live bird is discharged from the slanted live bird transfer cage 1. After the live bird is discharged from the live bird transfer cage 1, the live bird transfer cage module A is returned to the horizontal state by using the tilting mechanism, and the discharge door return mechanism swings the discharge door 5 inward to claw 14a. The claw 14a is pushed to elastically deform the door 5 so that the upper edge of the discharge door 5 is inserted between the claw 14a and the claw 14b to close the discharge door 5. The claw 14a regulates the outward swing of the discharge door 5, and the claw 14b regulates the swing of the discharge door 5 inward. As a result, the discharge door 5 closes in either the outward or inward direction.

If the live bird transfer cage module A is equipped with the first lock mechanism and the destination bird processing plant is equipped with the release mechanism of the second lock mechanism attached to the tilt mechanism, the first in the poultry farm. After the lock mechanism is removed from the live bird transfer cage module A and the second lock mechanism is attached to the live bird transfer cage module A, the live birds are carried into the live bird transfer cage module A and transferred to the bird processing factory. In the bird processing factory, the unlocking mechanism is used to unlock the discharge door 5, and then the tilting mechanism is used to tilt the live bird transfer cage module A to discharge the live birds from the live bird transfer cage 1.
If the live bird transfer cage module A is equipped with a second lock mechanism and the destination bird processing plant is equipped with a release mechanism for the first lock mechanism attached to the tilt mechanism, the second lock mechanism is provided at the poultry farm.

The installation procedure of the first lock mechanism is the reverse procedure of the removal procedure. After the first lock mechanism is attached to the live bird transfer cage module A, the live birds are carried into the live bird transfer cage module A and transferred to the poultry processing factory. In the bird processing factory, the live bird transfer cage module A is tilted by using the tilt mechanism, then the release door 5 is unlocked by using the unlock mechanism, and the live bird is discharged from the live bird transfer cage 1.

As can be seen from the above explanation, by selectively attaching the lock mechanisms 1 and 2 to the live bird transfer cage 1, it is possible to transfer to two or more poultry processing factories equipped with an unlock mechanism corresponding to each lock mechanism. become. By increasing the choices of bird processing factories to be transferred, it will be possible to flexibly respond to restrictions on the movement of live birds during an outbreak of bird flu and prevent an increase in transfer energy and breeding energy.
The live bird transfer cage 1 may be provided with a lock mechanism corresponding to the unlock mechanism of the poultry processing factory that transfers live birds in normal times. If other types of lock mechanisms are used as equipment for poultry farms, the lock mechanism can be replaced immediately in the event of an emergency.
By engaging and disengaging the rigid claws 9 and 11 from the discharge door 5, the discharge door 5 can be locked and unlocked.
The rigid claws 9 and 11 can be reciprocated and linearly moved to engage and disengage from the discharge door 5.
Since the stopper 4a and the claw 14b for restricting the inward swing of the discharge door 5 are provided, the discharge door 5 swings inward during the transfer and comes into contact with the live bird in the cage to damage the live bird. The occurrence of the situation is prevented.
By optimizing the dimensions and material strength of the claws 14a and 14b of the groove-shaped cross-section rubber 14, it is possible to prevent the discharge door 5 from opening to the outside due to inertial force or impact during transfer. In a bird processing factory, the discharge door may be forcibly opened by using an unlocking mechanism.
A plurality of live bird transfer cages 1 are arranged vertically and horizontally to form a live bird transfer cage module A, thereby improving the live bird transfer efficiency.
In the live bird transfer cage module A, the weight of the live bird transfer cage module A is reduced by sharing the boundary wall between the adjacent live bird transfer cages 1.
When the live bird carry-in door 3 faces the live bird discharge door 5, the flow line of the live bird becomes a straight line, and the live bird can be easily discharged from the live bird transfer cage 1. By making the live bird carry-in door 3 a swinging door that can swing inward, it becomes easy to carry live birds into the live bird transfer cage 1.
By providing the stopper 4b that regulates the outward swing of the live bird carry-in door 3, the live bird carry-in door 3 swings outward during the transfer, and the live birds in the cage are released to the outside of the cage. The occurrence of such a situation is prevented.

The lock mechanism of the discharge door is not limited to that of the above embodiment. Any lock mechanism may be used as long as the lock release mechanism is installed in the bird processing factory. For example, if the corresponding unlocking mechanism is provided in the poultry processing plant, the first locking mechanism is replaced with the shaped steels 6a and 7a instead of the claws 9 and 11 of the strip steel that reciprocates directly. It is composed of four upper and lower strip steel claws connected by hinges and all the rods hinged to the tips of the four claws, and the rods are moved up and down to swing the claws to make the tips of the claws. It may be disengaged from the discharge door.
In the above embodiment, the side wall of the live bird transfer cage 1 is made of steel net, but these may be formed of a synthetic resin lattice structure or a synthetic resin perforated plate.
In the above embodiment, there are two types of lock mechanisms, and each attachment portion is arranged in the live bird transfer cage 1. However, there are three or more types of lock mechanisms, and each attachment portion is arranged in the live bird transfer cage 1. You may. It will be possible to more flexibly respond to restrictions on the movement of live birds during an outbreak of bird flu and prevent an increase in transfer energy and breeding energy.
