摘要

The mechanism consists of two perch rods with struts which are supported so that they can turn upwards and downwards on a feed box. Six, wire ropes with six rollers are fixed to holders. Two rope distance holders prevent rope swing. Two sand buckets serve as weights. They open the door and hold the rotatable perch rods in an upwards inclined position when the hens are not on the rods. There are two guide strips for the slide and a slide with rope holders below the slip door. There is one perch rod at the side of the stall for about 20 hens.
