DESCRIPTION:
BRIEF SUMMARY
The invention is a cutter-mixer wagon for the recycling of plant residues, provided with a perfected conveyor belt for the extraction of the processed material.
It is well known that the composting of plant residues obtained by cutting plant residues and mixing them with other components is becoming a more and more important method for the production of fertilizers. This method, in fact, has no environmental impact and at the same time makes it possible to dispose of and reuse the plant residues produced through the maintenance of parks, orchards, gardens, woods and alike, which, as it is known, have very high fertilizing properties.
For the crushing of plant residues cutter-mixer wagons of the known kinds are generally used, in which the plant residues are loaded manually or by means of mechanical loaders or fork trucks, taking the plant residues from the ground or from appropriate areas where they have been heaped. As far as the disposal of plant residues in urban centres is concerned, they are put in special skips and this happens especially in those countries where the differentiated collection of waste is provided. The skips are transported near the cutter-mixer wagon or, alternatively, the plant residues are collected with any transport means and then transferred into the cutter-mixer wagon by means of the already mentioned manual loading devices, mechanical loaders or fork trucks.
The cutter-mixer wagons are provided with an unloading door in correspondence of which there is a device for the extraction of the cut and mixed material, which must be heaped, so that it can successively be collected and distributed on the areas to be fertilized.
Said extraction device comprises a conveyor belt, supported by a frame hinged to the cutter-mixer wagon, which, when it is in working position, is inclined in such a way as to be capable of unloading the material outside the cutter-mixer wagon, forming a heap.
One of the drawbacks of these conveyor belts is represented by the fact that, being inclined with respect to the cutter-mixer wagon to which they are hinged, they protrude from the outline of the cutter-mixer itself, especially when their length is considerable.
This creates handling problems when the cutter-mixer wagon must be moved from a working area to another.
There are some applications in which, in order to avoid said inconvenience, the conveyor belt is made up of two articulated parts, so that when it is at rest the two parts are bent with respect to each other and adhere to the walls of the cutter-mixer wagon, so that it is less cumbersome.
Solutions of this kind, though eliminating the problem of the conveyor belt that protrudes with respect to the wagon when this is at rest, are more difficult to carry out and therefore more expensive.
The present invention aims at eliminating said drawback through the implementation of a cutter-mixer wagon for the recycling of plant residues, provided with a conveyor belt for the extraction of the processed material, which, when at rest, adheres to the walls of the cutter-mixer wagon though being made of a single piece.
The above goal is achieved through the implementation of a cutter-mixer wagon for plant residues, which, according to the main claim, comprises: the introduction of said plant residues to be processed; and suitable for cutting said plant residues; container; conveyor belt being positioned in correspondence with said unloading door and supported by a frame connected to said container through connecting means, said cutter-mixer wagon being characterized in that said connecting means comprise oscillation means that connect said container to an intermediate point of said frame supporting said conveyor belt and sliding means that connect said container to the lower part of said frame, with operating means being connected to said container and to said frame and carrying out the reciprocal movement of said sliding means to obtain the oscillation of said frame around said oscillation means, in order to arrange said conveyor belt in a substantially vertic
