    • The machine has two laterally separated banks of pickers located on opposite sides of the path of travel of poultry carcasses conveyed through the machine. Each bank includes three horizontally extending lines of rotary pickers set in spaced opposition to the corresponding lines of pickers on the opposite bank so as to define a picking zone therebetween. The two banks may be rocked about a pair of respective horizontal axes extending parallel to the path of travel so as to adjust the shape of the picking zone to the extent needed for optimum performance, i.e., rocking the banks inwardly toward one another at their upper corners correspondingly brings the upper pickers closer together while separating the lower pickers and, on the other hand, rocking the banks toward one another at their lower corners causes the lower pickers to be brought closer to one another while the upper pickers are spaced further apart. The intermediate or middle lines of pickers are independently adjustable toward and away from one another relative to the other pickers, and both banks may be bodily shifted toward and away from one another to expand or contract the picking zone as may be necessary or desirable.
    • 该机器具有位于通过机器输送的家禽屠体行进路径相对两侧的两个侧向分离的拾取器。 每个组包括三个水平延伸的旋转拾取器线,其设置成与相对的组上相应的拾取器线间隔开,从而在它们之间限定拾取区。 两个组可围绕平行于行进路径延伸的一对相应的水平轴线摇摆,以便将拾取区域的形状调整到最佳性能所需的程度,即在它们的上部朝向彼此向内摇动组 角部相应地使上部拾取器更靠近在一起,同时分离下部拾取器,并且另一方面,在它们的下角处使堤彼此朝向彼此摇动,使得下部拾取器彼此靠近,同时上部拾取器间隔开。 拾取器的中间或中间线相对于其他拾取器可独立调节和相互离开,并且可能必要或期望的两个组可以彼此身体地彼此偏移并彼此远离以使收集区域膨胀或收缩。

    • A rotary picking unit has its drive shaft journaled by bearings that must be sealed against exposure to moisture and the escape of lubricant. A housing which contains the bearings is fitted at its open end with an annular seal that is disposed outwardly adjacent the bearings in surrounding, sealing relationship with the shaft which projects outwardly from the housing and carries feather picking means at its outer end. A close fitting sleeve, preferably of a synthetic resinous material, surrounds that portion of the shaft projecting outwardly from the seal and is held stationary during rotation of the shaft within the sleeve so as to keep feathers, grit and grime from working along the shaft and deteriorating the interface between the shaft and the seal. The stationary sleeve bears against the backside of a rotating disc of the picking means and has a beveled outer end so that only a thin, knife edge of the sleeve actually makes contact with the disc. This minimizes the risk of pinching fine feathers between the end of the sleeve and the disc and forcing them to work along the shaft as it rotates relative to the sleeve.
    • 旋转拣选单元具有轴承轴承的驱动轴,必须密封以防止潮湿和润滑剂溢出。 包含轴承的壳体在其开口端安装有环形密封件,环形密封件设置在与轴承外侧相邻的环境中,与从外壳向外突出的轴线密封关系,并在其外端承载羽毛采摘装置。 优选合成树脂材料的紧密套筒围绕着从密封件向外突出的部分,并且在轴在套筒内旋转期间保持静止,以便保持羽毛,砂砾和污垢沿着轴工作,并且 使轴和密封件之间的界面变差。 固定的套筒靠在拾取装置的旋转盘的背面,并且具有斜面的外端,使得只有薄的刀片边缘实际上与盘接触。 这最大限度地减少了在套筒端部和盘之间夹紧细羽毛的风险,并迫使它们在轴线相对于套筒旋转时沿轴运动。
