"Loading and pressing device for garbage trucks"

The present invention relates to a loading and pressing device for garbage trucks, in particular for garbage trucks of the type characterized, dars a substantially at the rear end is provided consisting of a feed press and an upper compacting press loading device, on the one hand for the transport of the garbage from the bulk space to the actual garbage container and the simultaneous formation of a temporary bulk space by means of this feed press and, on the other hand, for compressing and compacting the garbage in the garbage container with this for example Compaction press consisting of a rocking press.

As is well known, garbage trucks of this type are not only suitable for picking up loose garbage or garbage packed in plastic bags, but also of so-called coarse waste, if it is sieve to refuse packed in plastic bags, preferably means for tearing these bags open during their transport to the actual Rubbish bins are provided, on the one hand, to prevent waste from decomposing on the landfill due to a lack of air circulation to prevent in closed plastic bags and on the other hand, the pre-sorting of the garbage in specially equipped composting or To facilitate recovery operations.

For this purpose, the use of teeth or knives for compressing and tearing the plastic bags in question in the garbage truck has already been recommended. However, this has the disadvantage that the teeth are usually very obstructive in the processing of coarse waste and can even make this impossible because of the accumulation of waste behind the teeth.

The present invention relates to a loading and pressing device for garbage trucks of the type mentioned above, which completely eliminates the aforementioned disadvantage of the known systems and for this purpose is characterized in that the bottom of the garbage can or an extension of the same with a Row of teeth is provided and the top of the feed press can be adjusted and held at two different heights, and although in a first position, this top side at the same level as the bottom of the garbage can and in a second position, this top is at the same or greater height than the upper ends of the aforementioned teeth is located.

The characteristics and advantages of the system according to the invention will appear more clearly from the following detailed description of some Preferred embodiments come to light. This description, given without any restrictive intention, can be found on the basis of the enclosed Drawings instead of where

Figure 1 shows a longitudinal section of the rear part of a device equipped with a loading and pressing device according to the invention Refuse truck reproduces, with the loading press in its highest position for processing loose items or items packed in plastic bags Garbage is located;

Figure 2 is a partial view of the garbage truck in question corresponding to Figure 1, but that the feed press is in its maximum position for the processing of coarse waste;

Figure 3 shows a line III-III of the figure 1 shows the section made schematically on an enlarged scale;

Figure 4 shows a variant of the embodiment according to Figure 3;

FIG. 5 shows a view corresponding to FIG. 1 of a variant of the implementation of the system according to the invention;

Figure 6 shows a view corresponding to Figure 2 of the embodiment according to Figure 5;

Figure 7 schematically reproduces a section made along the line VII-VII of Figure 5; and

FIG. 8 shows a view corresponding to FIG. 1 of a second implementation variant of the system according to the invention reproduces.

In the case of the mode of operation explained in Figures 1-3 of the refuse truck according to the invention is an extension 1 of the base 2 of the actual refuse container with a row of teeth or knives 3 provided, the for example triangular teeth or knives 3 at suitable mutual distances on this extension 1 are attached. In the present case, the height of the teeth 3 is selected in such a way that the lower edge of the press 4 is unhindered can pass over the teeth to push the garbage into the garbage can.

The feed press 5 of the garbage truck in question consists of two parts 6 and 7, the part 7 being intended such that it

with respect to the part 6 or the teeth 3, at least two different ones Can occupy maximum positions, i.e. a first maximum position, with the upper side 8 of this part 7 at the same height as the Extension 1 of the bottom 2 of the actual garbage container, and a second maximum position, this upper side 8 being slightly higher than the top of the teeth 3 lies. The press 4 and the feed press 5 are suitably driven by means of a pressure cylinder respectively 9 and 10 instead.

This has the consequence that when transported in plastic bags packed garbage from the bulk space into the garbage container with a loading and pressing device according to the invention, which The maximum position of the feed press is not higher than the position shown in Figure 1, therefore the press 4 is filled with garbage Plastic sacks pushes over the teeth 3 into the garbage container, the plastic sacks being torn open by these teeth 3 while in the case of coarse waste processing, the feed press can assume a higher position, as shown in Figure 2, so that the coarse waste conveyed by the press 4 to the garbage container is simply pushed over the aforementioned teeth 3 and closed touch so that the teeth cannot prevent the garbage from being transported.

It can be seen from the foregoing that the inventive System on the one hand in a first high position the transport of loose garbage, of garbage in plastic bags and possibly of coarse waste, which requires additional shredding, and on the other hand, in the second maximum position, the transport of coarse waste in the garbage can.

The system according to the invention is of course suitable for

7737255 23.0a78

the most varied of designs with further maximum positions of the Feed press other than those described above according to the one through the teeth 3 Influences to be exerted on garbage.

Figure 4 relates to another embodiment of the tooth profile. The teeth 3 are suitable for the most diverse Modes of execution.

Figures 5-7 relate to an embodiment in which the plate 8 of the feed press 5 is also provided with teeth 11 whose profile in the vertical plane corresponds to that of teeth 3, behind which they are arranged. Even with this embodiment the garbage cannot accumulate behind the teeth 3 in the position illustrated in FIG.

There are implementation methods for all of the above of the system according to the invention the possibility of the lower edge of the press likewise with any orphan with regard to the teeth 3 and 11 arranged teeth, but the lower edge of the press 4 always remains above the teeth 3, as shown in the figures explain in dash-dotted lines.

Finally, the lower edge of the press 4 is in any case included according to the embodiment explained in FIG between the teeth 3 and 11 arranged. Teeth 12 provided, for example the joint 13 of this press 4 is displaced in such a way that the aforementioned teeth can move between each other.

The present invention is of course in no way limited to the exemplary embodiments described above, explained by the accompanying figures, but is suitable for the most varied of embodiments of the loading and pressing device in question in terms of shape and size, provided, of course, that the scope of the invention is not exceeded.
