Feed grid for cattle stalls - has neck guide interspaces with restraining devices operated by cows and featuring double levers

摘要

Feed grid for cattle stalls where there are top open neck guide interspaces and capture devices which are operated by the cows. The capture devices each have a double armed lever which can pivot parallel to the grid wall, are supported on side struts while the top arm is bent towards the other side and can be fixed in the closed position by a central lock. This lock has an operating rod with fixed stops for locking or unlocking the double arm lever. Specifically, the top lever arm (11a) of each lever (11) is bent over an obtuse angle and to achieve stable end positions is heavier than the bottom straight lever arm. A pawl (15, 16) which acts with every stop (18) of the operating rod (20) is fitted to the bottom arm of each double lever (11). This pawl has a lug (19) for individual unlocking.
