    • A screen system employs a resiliently mounted housing, a vibration generator mounted to the housing, a mounting frame fixed to the resiliently mounted housing and a support surface. This system receives a screen including a screen frame and pre-tensioned screen cloth. The frame includes an inwardly extending mounting flange accessible from below the screen when placed in the housing. Clips pivotally mounted relative to the mounting frame include a first rounded lever extending upwardly to selectively engage the inwardly extending mounting flange. Second levers extend downwardly to cooperate with actuators. The actuators include inflatable bodies with contacts which, upon inflation, force the clips to engage the inwardly extending mounting flanges. This engagement retains the screen on a resiliently mounted housing and is able to further tension the screen in place.
    • 屏幕系统采用弹性安装的壳体,安装到壳体的振动发生器,固定到弹性安装的壳体的安装框架和支撑表面。 该系统接收包括屏幕框架和预张紧的筛布的屏幕。 框架包括一个向内延伸的安装凸缘,当安装在外壳中时可从屏幕下方进入。 相对于安装框架枢转地安装的夹子包括向上延伸以选择性地接合向内延伸的安装凸缘的第一圆形杆。 第二杆向下延伸以配合致动器。 致动器包括具有接触件的充气体,其在充气时迫使夹子接合向内延伸的安装凸缘。 该接合将屏幕保持在弹性安装的壳体上,并且能够进一步将屏幕紧固在适当位置。
