Abstract: A rotary milking parlor milker detacher having a pivoting support arm and retracting chain arrangement that is synchronized with a rotating platform position to move the detacher between a storage position, a presentation position, and a milking position to protect the detacher from damage and provide a superior ergonomic design that reduces operator fatigue and turnover.

Abstract: A support for positioning a milker unit beneath a cow has a shaft which is vertically movably mounted on a base. An arm on the shaft supports a milker unit beneath a cow. Air pressure is applied to the shaft to hold the shaft and arm at a desired vertical position. A control automatically adjusts the vertical position of the support so that when the milker unit is attached to a cow's teats the weight of the milker unit is applied solely to the cow's teats. The control includes a pair of valves each connected to a supply of air under pressure. A first of the valves has an open position in which the amount of pressure applied to the support decreases and the support is permitted to lower. A second of the valves has an open position in which air from the supply moves the first valve from a normally closed position to the open position thereof. The control has a lever mounted on the arm for moving the second valve to the open position thereof when the milker unit applies force to the lever.

Abstract translation: 用于将奶牛单元定位在母牛下方的支撑件具有可垂直移动地安装在基座上的轴。 轴上的一个臂支撑着一头奶牛下方的奶牛单位。 将空气压力施加到轴以将轴和臂保持在期望的垂直位置。 控制器自动调整支架的垂直位置，以便当奶嘴单元连接到奶牛奶头时，奶嘴单元的重量仅适用于牛奶的奶嘴。 该控制器包括一对各自连接到压力下的空气供应的阀。 第一阀具有打开位置，其中施加到支撑件的压力量减小并且允许支撑件下降。 第二阀具有打开位置，在该位置，来自供给装置的空气将第一阀从常闭位置移动到其打开位置。 控制器具有安装在臂上的杠杆，用于当挤奶器单元向杆施加力时将第二阀移动到其打开位置。
