A manure-removal installation has a conveyor for the manure, it being possible for the conveyor to be driven back and forth via a hydraulic cylinder/piston unit, the activation of which is controlled by a reversing slide 7. For the purpose of actuating the reversing slide, use is made of an over-dead-centre ratchet mechanism 10 to 22, of which the actuating element 18, 19 is retained by a spring 21 in one of two possible end positions, corresponding to the two directions of activation of the cylinder/piston unit, and can be adjusted out of the respective end position via end stops 3, 4 adjusted by the cylinder/piston unit, with the result that the actuating element, once it has passed a dead-centre-like intermediate position, and possibly leading the actuating stop 3, 4 which is currently in action, is adjusted by the spring 21 into the other switching end position. <IMAGE> |
