GRINDING CONTAINER FOR THE SELECTIVE COLLECTION OF SOLID URBAN WASTE AND VARIOUS SPECIAL ADAPTATIONS FOR EACH TYPE OF WASTE, INCLUDING A DOMESTIC GRINDING CONTAINER

摘要

The invention relates to a system comprising specialised domestic grinding containers, the manual version of which is completely environmentally friendly. The inventive system can be used to reduce the excessive amount of varied urban waste generated by daily consumption, using a system of piercing/crushing blades which are disposed transversely on the supporting shafts thereof and which, when sufficiently locked together, enable waste to be reduced to one-fifth of the initial volume thereof by specially arranging the shafts and using different types of blades and hammers for each type of waste (plastics, cans, tetra bricks, paper, glass, organic material and another combined blade system for refuse). The system is essentially characterised in that the movement of the blades is produced by a particular system of toothed wheels which, in the manual version, are actuated by opening the upper lid which, facilitated by a simple pedal which assists in opening said lid, actuates lateral toothed cylinders located inside the container which in turn actuates the toothed wheels located inside each of the lateral cylinders which, located at each of the ends of the four blade shafts thereof, rotate the shafts in a special manner in order to actuate a grinding function and to draw waste into the container, greatly reducing the volume thereof. The specialised manual and electric grinding containers and the different stationary and mobile embodiments intended for domestic use reduce the significant time and monetary costs involved in transporting said waste both from homes to containers on public roads and from such public containers to the respective recycling plants thereof. Waste recycling plays a role in preventing the transformation of more natural resources and reducing the abuse of more scarce natural resources and is facilitated through the use of these specific types of grinding containers having the above-mentioned specialised blade systems. Thanks to the dual function comprising the lateral oblique torsion and elastic rotation of each blade independently of one another, said containers can help to achieve the recycling objectives imposed by Directive 2004/12/EC on the member states of the European Union, in its second transposition phase, and all that is needed is the will to grind waste (see illustrative drawing, Figure 2.2 and 2.3).
