Definitions

• the present invention relates to an autonomous device for sucking up waste and grinding the lightest.
• the technical field of the invention is the field of the construction of cleaning apparatuses and their use by methods using a draft of suction air.
• the main application of the invention is the collection of waste of all kinds on public roads, therefore outside and without external power supply source.
• Such a suction device is quite heavy and complex, representing a mass of more than 80 kilos that the operator must therefore move by pulling or pushing said carriage to bring it to the places where it must vacuum the waste; moreover, such a device which functions like a conventional vacuum cleaner, fills up very quickly when aspirating bulky waste, and if these are light, they come to obstruct the orifice of the said vacuum hose, connected to the block of suction, thus stopping any possibility of continuing cleaning, after about 30 seconds of use, which is very short and ineffective.
• the problem posed is in fact to be able to produce and use an autonomous device for sucking up all the waste that can be encountered on public roads, using containers, preferably of the standard type and that we want to be able to fill to the maximum.
• said waste without being too quickly obstructed by bulky and light waste, while proposing a device simple, light, easily movable by an operator, of a great autonomy and without risk of damaging the device , of aspiration, while being of a reasonable cost price, thus allowing any community to be equipped with 'a big number .
• the present invention makes it possible to achieve all of these objectives by means of a device for sucking up any type of waste in a standard container by physically selecting light low density waste for grinding it, and ejecting it in a collection bag, while the heavy waste inertially falls into the container.
• a solution to the problem posed is in fact an autonomous device for sucking up the waste, comprising a cover capable of constituting a cover for covering and closing the opening of a waste container, a suction block able to create a vacuum in said container by a suction opening opening into said cover and a suction pipe, one end of which is movable so as to be moved to any point where it is desired to suck up a waste and the other end is connected to said cover through which it opens ;
• the suction block is directly mounted on said cover with its inlet orifice constituting said suction opening therein, which suction block is capable of grinding light waste, and its orifice delivery is connected to a container for collecting said crushed waste, said container constituting the receptacle for heavy waste;
• said container for collecting crushed waste is preferably a bag, at least part of the envelope of which is porous to let the pressurized air pass through which is blown by said suction unit and retain said crushed waste, which bag is mounted laterally suspended from said cover.
• said cover comprises a peripheral rim whose bearing surface is of shape and dimension compatible with that of the peripheral rim outside the opening of the container, which bearing surface is equipped with a seal hollow or at least flexible enough to crush in places and thus accept the surface deformations, which joint being able to press on said peripheral rim of the container and to make its opening watertight relative to the cover, while absorbing the vibrations of the engine.
• the device according to the invention allows the suction turbine, the diameter of which is preferably greater than that of the suction pipe manipulated by the operator, to create therein a suction at high speed of the 'order of 5 to 6 meters per second and even beyond, insofar as the seal between the suction device and the container is sufficiently well achieved, thanks in particular to the seal according to the present invention, which moreover, by its shape, absorbs vibrations of the drive motor and reduces noise pollution;
• the air flow thus created at the end of the suction pipe thanks to its high speed, can carry heavy objects and waste such as cement, stones, and can even be of density from 4 to 5 for example, and all the more so since their bearing surface in relation to the flow of the suction air is large in proportion to the section of the suction pipe: which waste then arrives at the top of the container , the opening section of which is of course larger than that of the suction pipe, which causes the air drive speed to drop, thus not making it possible to deflect said heavy waste, which has acquired a speed d quite significant en
• Such a device is relatively compact and remains operational as long as either the light waste bag or the heavy waste container is not full; it represents an empty weight of the order of 6 to 7 kilos maximum, which can thus be easily handled and loaded, even on two-wheeled vehicles, since it is directly mounted on the associated container, without requiring any intermediate support.
• the flow rate that can be obtained with such a device, with a thermal type drive motor of less than one kilowatt can be 10 m per minute, or three times that of conventional vacuum cleaners with electric power, allowing therefore better suction efficiency while requiring less power than all the other types of suction devices mentioned above; indeed, these require a higher power because to avoid damaging the suction system, they all have a tight mesh filter before the suction opening to stop any type of waste heavy or light.
• a thermal type drive motor of less than one kilowatt
• Figure 1 is a schematic side sectional view along II 'of Figure 2B, of a device mounted on a standard container according to the invention.
• Figure 2A is a view of the same device as that of Figure 1, but shown alone laterally.
• Figure 2B is a bottom view of the cover of the device of Figure 2A.
• Figure 3 is a side view of the same device according to the invention as in Figures 1 and 2A, but with a connection of the flexible suction duct, mounted radially on the side of the cover and not axially and vertically as in the other figures .
• FIG. 4 is an enlarged view in partial section of part IV of the device shown in FIG. 1.
• the device according to the invention consists of a cover 1 specially adapted for hermetically covering with a seal 6 the opening 4 of a waste container 5 mounted on wheels 12.
• the cover 1 integrates and supports the suction unit 2 consisting of a suction and grinding turbine 2 ⁇ of light waste 22 2 and whose rotation is ensured by a drive motor 3, preferably of the thermal type with petrol, complying with pollution and noise standards and located on top of hood 1.
• the latter is also provided with an orifice 7 arranged to receive a flexible low pressure conduit 8 equipped at its other end with a tube 10 intended to transport the waste 22 sucked in, for example on the ground 24.
• the device thus formed allows heavy waste 22 to fall by inertia into the container 5, while low density waste 22 2 is sucked by the turbine 2 and crushed before being ejected through its discharge orifice 23 in a bag collection 9 placed laterally.
• the flexible conduit 8 equipped at its movable end 10 with said tube 10, can be manipulated by a holding handle 11 which is provided with said tube 10.
• Said holding handle 1 1 is equipped with a handle 14 arranged to control the acceleration of the drive motor 3 of the suction unit 2, by any mechanical or electrical connection not shown in the figures.
• said cover 1 has a peripheral flange 17, which may be in the form of a flange, the bearing surface of which is of shape and dimension compatible with those of the peripheral flange 16 outside the opening 4 of container 5, which bearing surface is equipped with a flexible seal, deformable in its thickness, or preferably hollow 6, capable of pressing on said peripheral rim of the container 4.
• a seal in addition to the seal that it ensures, even in the event of deformation of the flatness of the rim 16 of the container, also absorbs the vibrations of the motor 3 which are thus not transmitted to said container 5, thus limiting not only noise pollution but also mechanical deterioration from the whole.
• said hollow anointed j 6 comprises a groove 20 whose opening oriented towards the center of the cover 1 parallel to the bearing surface of the rim 17 is capable of threading externally, straddling said rim which is then necessarily in the form of a flange or has a lip for this; it is thus very easy to be able to remove and change the seal 6 as appropriate.
• said cover 1 comprises at least two attachment systems 13 placed at its outer periphery, and constituted at least a flexible part 18 fixed and articulated on said cover 1, and a rigid part 19 capable of coming to engage under the peripheral rim 16 outside of the container 5.
• the orifice 7 of the duct 8 can be installed, either vertically on the cover 1 as shown in FIGS. 1 and 2A, considering the vertical position, that of the container 5 placed on the floor 24 as shown in Figure 1, and according to another variant as shown in Figure 3, said orifice 7 can be mounted horizontally.
• the device according to the invention is thus particularly intended for aspirating any type of waste 22 strewing on the public highway or any other open public or private space 24, in town as in the countryside.
