<p>The invention relates to a device that is capable of being fitting on a loader 12 wherein the push bucket 1 has: a) a compacting means 2 connected to vibrators 5; b) a leveling means in the form of a transverse blade 26 attached onto the rear edge of the compacting means 2; and c) a resilient means positioned between the compacting means and the bucket 1. With the aim of improving the leveling and compacting, the compacting means consists of two plates 2 that are independent of each other and transversely juxtaposed, the front ends of which are hinged to 3 under the bucket 1 and the rear edges of which, having separate leveling blades 26, are connected to hydraulic cylinders 6 that are capable of pivotably moving the blades independent of one another so as to adjust the inclination thereof relative to the bucket 1, as well as bear against the spring means 22 that is positioned between the blades and the bucket. In one embodiment, the control means 13 cuts off the supply of power to the cylinders 6 when the vibrators are placed in motion so that the plates 2 are floating and only exert the pressure of the spring means 22 thereupon.</p> |
