Compared with the existing technology, the advantages of the present invention are:

In the existing three-dimensional free-range perch system, the feeding trough and egg collecting trough are on the same side. Due to the egg rolling angle, the bottom net is tilted towards the feeding trough and egg collecting trough. Therefore, the bottom net on the side near the feeding trough is not in contact with the upper manure cleaning belt. If there is a large vertical space between chickens, the chickens will eat on top of each other, which will lead to damage to the feathers on the back. In the cage of the present invention, the feeding trough and the egg collecting trough are on opposite sides, the egg collecting assembly is arranged in the inner walkway, and the bottom net is tilted toward the inner walkway, thereby reducing the vertical space between the bottom net on the side near the feeding trough and the upper manure cleaning belt. Prevent chickens from stacking feeds, thereby reducing the occurrence of feather damage to chickens.

In the present invention, the egg collecting assembly is arranged in the inner walkway, and there is no need to reserve a gap for rolling eggs on the lower side of the feeding trough, thus avoiding the situation in the three-dimensional free-range perch system due to the small size of the chickens when they first move to the flock, passing through the feeding trough. The phenomenon that the eggs escape from the cage in the gap between the lower side and the egg collecting trough.

Since the inner vertical pole is arranged at an angle in the present invention, the distance between the connection point between the top end of the first inner vertical pole and the first cross beam and the connection point between the top end of the first outer vertical pole and the first cross beam is smaller than the connection between the bottom end of the first inner vertical pole and the second cross beam. The distance between the connection point between the bottom end of the first outer vertical pole and the second crossbeam, the distance between the connection point between the top end of the second inner vertical pole and the first crossbeam and the connection between the top end of the second outer vertical pole and the first crossbeam is smaller than the distance between the connection point between the top end of the second inner vertical pole and the first crossbeam The distance between the connection point between the bottom end of the pole and the second cross beam and the connection point between the bottom end of the second outer vertical pole and the second cross beam. The horizontal distance between the first inner vertical pole and the first outer vertical pole decreases as the distance from the ground increases. small, the horizontal distance between the second inner vertical pole and the second outer vertical pole decreases as the distance from the ground increases, and then reaches the point between the first inner vertical pole and the first outer vertical pole, and the second inner vertical pole and the third outer vertical pole. The bottom nets of different heights and widths are respectively provided between the two outer poles for different purposes. The bottom net is set up in a ladder shape. When the chicken falls from the edge of the upper bottom net, the lower bottom net acts as a buffer to prevent the chicken from falling directly to the bottom of the system, reducing the height of the chicken's fall, thereby reducing the damage to the chicken's keel.

Since the egg collecting assembly is arranged in the inner aisle of the present invention, in order to prevent eggs from being contaminated by feces or being pecked by chickens, the egg collecting assembly includes an egg collecting trough, an egg collecting trough cover and an egg collecting belt. The egg collecting trough cover is Located on the upper side of the egg collection trough, the area of the egg collection trough cover projected to the ground is larger than the area of the egg collection trough projected to the ground. The egg collection trough cover not only protects the eggs in the egg collection trough, but also provides chickens with More space for activities.

Since chickens like to lay eggs in hidden places, during the peak period of egg laying, chickens may stack up to lay eggs or other chickens may trample on the backs of chickens when they lie down to lay eggs, which may also cause feather damage on the backs of chickens. The invention is provided with egg-laying partitions. The egg-laying partitions are arranged at the bottom net of the highest layer. The egg-laying partitions are parallel to the plane where the bracket is located. The egg-laying partitions are arranged every 60cm in the direction perpendicular to the plane where the bracket is located. This is The chickens provide cover to prevent stacking of eggs.
