    • An automatic animal watering apparatus includes a dish having an automatic watering valve disposed therein. When the valve is first closed, a water level in the dish is at a maximum level, and a hydraulic source pressure acts only across a smaller cross-sectional area of a valve seat which is closed by the valve, thus requiring only a first lower buoyancy force acting on a valve actuator float to maintain the valve closed. The water level can then drop from the maximum water level to a minimum water level before the hydraulic force action on the valve overcomes the first lower buoyancy force on the actuator float and reopens the valve. Then when the valve opens, the hydraulic source pressure acts against a larger cross-sectional area of the valve, thus requiring the buoyancy forces acting on the float to rise to a second higher buoyancy force to reclose the valve. The automatic watering device may be mounted on an external structure through the use of a mounting bracket, and removable mounting pins may connect the dish, the mounting bracket and a cover plate of the dish.
    • 一种自动动物浇水装置,包括具有设置在其中的自动浇水阀的盘。 当阀首先关闭时,盘中的水位处于最大水平,并且液压源压力仅作用在由阀关闭的阀座的较小横截面积上,因此仅需要第一低位 作用在阀致动器浮子上的浮力保持阀关闭。 然后在液压力作用于阀之前,水位可以从最大水位下降到最低水位,克服了执行器浮子上的第一个较低的浮力并重新打开阀。 然后当阀打开时,液压源压力作用在阀的较大横截面积上,因此需要作用在浮子上的浮力上升到第二较高的浮力以重新闭合阀。 自动浇水装置可以通过使用安装支架安装在外部结构上,并且可拆卸的安装销可以连接盘,安装支架和盘的盖板。

    • A drawbar apparatus for a cart, wagon or trailer. The drawbar apparatus includes a shaft having a first end suitable for connection to a cart, and a second end including a hitch coupling. The drawbar includes a handle member having a handle first end and a handle second end. The handle first end is pivotally connected to the shaft, and the handle second end includes a grip or gripping region. The handle member is selectively pivotal between a first position and a second position, the hitch coupling extending distally beyond the handle member in the first position, and the handle member extending distally beyond the hitch coupling in the second position. Some embodiments further include a lock configured to selectively secure the handle member when the handle member is in the first position and the second position.
    • 用于推车,货车或拖车的牵引杆装置。 牵引杆装置包括具有适于连接到推车的第一端的轴,以及包括联接联接器的第二端。 牵引杆包括具有手柄第一端和手柄第二端的把手构件。 手柄第一端枢转地连接到轴,并且手柄第二端包括手柄或抓握区域。 手柄构件选择性地在第一位置和第二位置之间枢转,所述搭接联接器在第一位置中向远侧延伸超过手柄构件,并且手柄构件在第二位置向远侧延伸超过联结联接件。 一些实施例还包括被配置为当手柄构件处于第一位置和第二位置时选择性地固定手柄构件的锁。
