<p>The apparatus for transferring manure normally comprise pumping means having hydraulic cylinders and a system of valves which permits the pumping of the manure during the forward course, but prevents the suction of that material during the reverse run. In this invention we use a hydraulic assembly provided with a mobile pumping chamber in which a piston is activated by a cylinder, and another hydraulic assembly having a rod connected to the said mobile chamber. A connecting frame between the cylinder of the first hydraulic assembly and the cylinder of the second hydraulic assembly can pivot in respect to a hopper, where these two assemblies are normally located. In this way, when necessary, the complete removal from the hopper of the two hydraulic assemblies becomes possible.</p> |
