Laying nest provided with an improved ejection system
A laying nest is provided with an improved ejection system, in which the risk of expelling eggs together with the hens is suppressed. The floor of the laying nest can rotate in both directions. Thanks to this arrangement, at first it can be rotated in a first direction for inclining it towards the egg collection area and ensuring that all the laid eggs are removed; next, it can be rotated in a second, opposite direction for inclining it towards the hen coop and thus expelling the hens from the laying nest. In a preferred embodiment, the driving arrangement of the ejection system of the laying nest is entirely arranged below the floor of the laying nest, so as to not occupy room in the laying nest and to be protected from manures and dirt that may be present in the laying nest.
1. A laying nest, comprising:
a floor, a roof, and side walls including a first side wall, comprising an entry opening, and a second side wall, opposite to the first side wall and comprising a discharge opening,
wherein the floor is a platform,
wherein the platform is rotatable about a first rotation axis which is parallel to the first side wall and adjacent to the first side wall, and the platform is rotatable about a second rotation axis which is parallel to the second side wall and adjacent to the second side wall,
wherein the laying nest has a driving arrangement for rotating the platform about the first rotation axis and the second rotation axis, and
wherein the driving arrangement comprises a rotation shaft, arranged below the floor, substantially at a middle position, which rotation shaft is rotatable in both opposite directions, and a rocker, which is integral to the rotation shaft and comprises two diametrically opposed arms which are arranged for coming into contact with and exerting a pressure onto a first side of the platform which is adjacent to the first side wall and onto a second side of the platform which is adjacent to the second side wall, respectively.
2. The laying nest according to claim 1 , further comprising:
a first rotation pin arranged parallel to the first side wall and adjacent to the first side wall and the floor, at the first side of the platform that is adjacent to the first side wall, and
a first engaging element configured to releasably engage the first rotation pin,
wherein, when the first engaging element is engaged with the first rotation pin, the floor is able to be rotated about the first rotation pin, and
wherein the first engaging element has a portion of cylindrical surface having a longitudinal axis parallel to the axis of the first rotation pin and a diameter substantially equal to the diameter of the first rotation pin.
3. The laying nest according to claim 2 , further comprising:
a second rotation pin is arranged parallel to the second side wall and adjacent to the second side wall and the floor, at the second side of the platform that is adjacent to the second side wall, and
a second engaging element configured to releasably engage the second rotation pin,
wherein, when the second engaging element is engaged with the second rotation pin, the floor is able to be rotated about the second rotation pin, and
wherein the second engaging element has a portion of cylindrical surface having a longitudinal axis parallel to the axis of the second rotation pin and a diameter substantially equal to the diameter of the second rotation pin.
4. The laying nest according to claim 1 , wherein one or more extensions are provided on a lower face of the floor and the arms of the rocker act onto the floor either directly or indirectly through the one or more extensions.
5. The laying nest according to claim 4 , wherein the ends of the arms of the rocker are provided with respective idle wheels.
6. The laying nest according to claim 1 , wherein the floor is mounted to the laying nest so as to be completely removable from the laying nest.
7. The laying nest according to claim 1 , wherein ends of the arms of the rocker are provided with respective idle wheels.
8. The laying nest according to claim 1 , further comprising:
a rotation pin arranged parallel to the second side wall and adjacent to the second side wall and the floor, at the second side of the platform that is adjacent to the second side wall, and
a second engaging element configured to releasably engage the rotation pin,
wherein, when the second engaging element is engaged with the rotation pin, the floor is able to be rotated about the rotation pin, and
wherein the second engaging element has a portion of cylindrical surface having a longitudinal axis parallel to the axis of the rotation pin and a diameter substantially equal to the diameter of the rotation pin.
