Reciprocating paddle bar for removing stable manure - has rocking switch latch and limit switches to control push bar movement

摘要

The floor duct in a stable is provided to transfer the manure slurry to the outside of the building. A reciprocating push bar (2) to which transfer paddles are attached is controlled by a rocking switch latch (3). On each end of the oblong latch (3), a tooth (6a, 6b) is provided which engage in slots in the push bar. When the push bar with the transfer paddles reaches one end position, the switch latch (3) operates an end switch which reverses the motion of the push bar. At the same time, the switch latch (3) rocks about a fixed support pin (9) due to imbalance. The push bar (2) pulls the latch along until it triggers a second limit switch at the other end of the stroke.
