Automatic cleaning device for use in a livestock farm

摘要

The invention provides an automatic cleaning device for use in a livestock farm, with an automatic switching system, a transmission casing, a sprayer system and a water pump. The automatic switching system uses water pressure in order to push a valve seat forwards, so as to achieve an automatic switching effect without using electric power. By means of a grooved drive rod, a first and second rotary rod and a single-direction bearing in the transmission casing, interacting with a switching lever and a connecting tumbler hook of the sprayer system, a rectilinear movement of a slidable piston is converted into an accelerated up-and-down hinged movement and a left-and-right swinging movement of a spray head of a sprayer system. A flow-control mechanism of a hydraulic component is used to achieve alternately quick and slow cleaning of the sprayer system. By differently selecting the pivot holes of a connecting member for pivotable connection to the switching arm, it is possible to adjust a starting point of the spray head.
