The characteristics of the ladder-typelayer chicken cage equipmentare: the upper and lower chicken cages do not overlap or overlap slightly, and there is no device such as a dung board or a scraping board between each layer of cages, and the excrement automatically falls into the pit. Its rack type, according to the connection mode of the rack and the chicken cage, can be roughly divided into two categories: 1. The cage bottom net rests on the rack. 2. The bottom net of the cage is not in contact with the frame, and the other mesh of the cage is connected to the column of the frame.

The common feature of the hanging type is that the cages are inserted into the beams of the frame. The utility model has the advantages of simple structure and less material, and the disadvantage is that the installation is troublesome, and the frame must be disassembled when assembling the chicken cage; the frame diagonal support is inserted into the cage, which occupies the space of the cage and is unfavorable for the growth of the chicken. The trough is installed on the front net, which increases the deformation of the chicken cage; the trough is mounted on the diagonal strut of the frame, and the chicken cage is not deformed.

The types and advantages of the hanging type are:

1. There is no ground support, and all the weight is borne by the adjustable suspension rod, so the cleaning of the dung is convenient and the air circulation is better. However, the beam cantilever length and steel strength requirements are high, and it is more troublesome if it is athree-tiered layer chicken cage.

2. The trough and the trough are placed on the rack, which will not deform the chicken cage. The disadvantage is that there are too many materials.

3. The beam does not pass through thechicken battery cage, it is easy to assemble, does not occupy the cage space, and the trough is installed on the beam.
