Description

The present invention relates to a bucket for collecting and

  transport of a load of household waste type.

  It relates more particularly to a grab for the collection and transport of waste, associated in particular with a vehicle or a trailer and which is provided with a device for compacting said waste so as to reduce the latter and to load a

  maximum waste in minimum volume.

  We already know, in particular by the French patent application FR-A-2 759 989 filed on February 27, 1997 by the present

  applicant, in which a bucket of the type described above is described

  above which is provided with a mobile gland shield under the action of a jack intended to compact the waste, the latter being provided in its upper part with a flap composed of a transverse beam secured to two parallel arms pivoting under the 'action

  a jack so as to compress the waste towards the bottom.

  This type of compacting device is satisfactory; however, for light waste, for example of the plastic bottle type, it turns out that the latter, during the phases in particular of loading the waste, collected beforehand in containers, in the bucket or even during compaction outside the bucket thus causing the operator to manually pick up

all this waste evacuated.

  The object of the present invention is to remedy the drawback

mentioned above.

  For this purpose, the present invention relates to a bucket for the collection and transport of a load of the household waste type, consisting of a bottom, two side walls, a front wall, a rear door forming receptacle, and a roof covering the major rear part of said receptacle so as to provide an opening in the front part of the bucket for loading the load, said bucket being provided with a substantially vertical wall movable in the bottom of that -ci under the action of a jack, characterized in that it comprises a device for compacting the load in particular towards the bottom which consists of a first flap articulated around a transverse axis located in the upper part of said movable vertical wall and of a second flap articulated around a transverse axis located at the upstream end of the roof to the right of the opening, these flaps being able to pivot around their respective axis between a first positio n opening for loading the load and a second closed position for compacting said load under the respective action of at least one jack, and in that said flaps are shaped so that in position d opening these form a hopper for the

load loading.

  According to an advantageous characteristic of the present invention, the second component consists of a first element and of a second element that can be folded over said first element, the first element being articulated around the transverse axis located at the upstream end of the roof. and the second element being articulated about an axis parallel to the axis of the first element which is integral with the free end of said

first element.

  According to a variant of the present invention, the second flap has the general shape of any triangle in longitudinal section thus defining two transverse walls which meet at a contiguous end forming the top of the triangle and in that the end opposite to the the joining end of one of the walls is articulated around the transverse axis while the end of the other

  walls is connected at least to the rod of at least one jack.

  According to another advantageous characteristic of the present invention, the first flap is shaped to slide in position

  of closing said flaps under the second flap.

  According to yet another characteristic, the bucket is provided with a removable transverse bar or articulated around a vertical axis integral with one of the side walls which is disposed substantially in the middle part of the bucket, so as to limit

  the return of the compacted waste towards the front thereof.

  According to another advantageous characteristic, the movable vertical wall has openings allowing the passage of longitudinal bars fixed on the one hand to the bar and on the other hand to the wall

  front of the bucket through, for example, pins.

  According to yet another characteristic, longitudinal non-return bars of the waste are hingedly connected at one of their ends around a transverse axis integral with the bar which

  are located in the rear part of said bucket.

  According to a variant, the bucket is provided with a transverse non-return waste flap which is articulated around transverse axes integral with the side walls substantially in the middle part of

the bucket.

  According to another characteristic of the present invention, the first flap is provided in the vicinity of the articulation of said flap with a valve freely articulated about a transverse axis parallel to the articulation axis intended to be pushed towards the before the dumpster with the waste so as to obstruct a space formed between

  the joint of the flap and the vertical wall.

  According to another advantageous characteristic, the first flap includes perforations intended to allow an operator to control. According to yet another characteristic, the first flap is provided with two surfaces for compacting the waste, one of the faces of which is disposed substantially vertically and the other of the faces of which is disposed substantially horizontally, in the closed position of said

first part.

  According to another characteristic, a telescopic jack is disposed substantially vertically between the bottom of the bucket and a cradle on which the bucket rests so as to tilt the said bucket around a transverse axis located in the

rear part of the bucket.

  We have described below, by way of nonlimiting examples, two embodiments of a bucket for the collection of waste provided with a device for compacting a load according to the invention, with reference to the drawings. annexed among which: - Figure 1 is a schematic longitudinal sectional view of a vehicle provided with a bucket equipped with the compacting device according to the present invention according to a first embodiment, - Figures 2 to 4 are views longitudinal section of the bucket illustrating different positions of the compacting device according to the invention, - Figures 5 and 6 are front views of the upstream part of the bucket illustrating the different positions of a locking mechanism allowing respectively the movement of 'a gland shield in the bottom of the bucket and the tilting movement of the bucket, - Figure 7 is a view similar to Figure 1, showing the bucket in the tilting position of the latter - Figure 8 is a top view of the bucket according to the invention, - Figure 9 is a view similar to Figure 1 according to a second embodiment of the invention, - Figures 10 and 11 are longitudinal section views illustrating different positions of the compacting device according to the present invention, - Figure 12 is a top view of the bucket according to the second embodiment, and - Figures 13 and 14 are front views illustrating an assembly

  of the bucket on a chassis and its locking mode on it.

  FIG. 1 shows a road vehicle 1 for collecting waste, for example of the plastic bottle type, which, in known manner, comprises a chassis 2, a front cab 3 for driving, wheels 4 driven by a motor to allow its displacement. The chassis 2 carries at the rear, in a known manner, a bucket 5 consisting of a bottom 6, two side walls 7, a front wall 8, a rear door 9 together forming a receptacle, and a roof covering the major rear part of said receptacle, as more clearly visible in FIG. 1, so as to provide an opening 11 in the front part of the bucket 5 for loading

waste or charge.

  The bucket 5 is arranged on a cradle 12 and articulated in its rear part thereto, about a transverse axis 13, so as to allow the tilting of the bucket 5 around this axis 13 under

  the action of a jack 14, during the emptying phases of the bucket.

  The cradle 12 is held on the chassis 2 by means of a fitting 15 which will be described in more detail below.

description.

  This chassis 2 also comprises, in known manner, between the cabin 3 and the bucket 5 a lifting means 16, of the crane type,

  different containers 17 or waste collection column.

  The bucket 5 is provided with a substantially vertical wall 18,

  designated in the following description, the gland shield, which is

  movable in the bottom 6 of the latter under the action of the jack 14. This gland shield 18 is extended longitudinally towards the rear door 9, in its lower part symmetrically with respect to a median longitudinal axis by a tunnel 19 in which the jack 14 is housed, as can be seen more clearly in FIG. 1. The jack 14 is, conventionally, constituted by a body 20 fixed at one of these ends around a joint 21 integral with the cradle 12 and

  a rod 22, the free end of which is fixed to the tunnel 14.

  Note that at the right of this tunnel 19 in the gland shield position 18 pushed against the front wall 8, the bottom of the bucket is provided with an opening 23 so as to allow passage and

cylinder deflections 14.

  The downstream end 24 of the tunnel 19, considering FIG. 1, is guided by a beam 25 having for example the general shape of an "I" which is arranged longitudinally along the median axis of

  said bucket, in the rear part on the bottom of the latter.

  Locking means 30 intended to select either the displacement of the gland shield 18 longitudinally in the bucket or a dump body, as shown in FIG. 7, are arranged at

the front of the bucket.

  These locking means 30 consist of latches 31, 32 respectively intended to engage in orifices 31a, 32a made in yokes, as shown in Figures 5 and 6, which are movable transversely under the action of a lever control 33 so as to lock either the front of the bucket with the cradle by engaging the latches 31 (Figure 5) or the shield

  gland 18 with the bucket engaging the locks 32 (Figure 6).

  According to the present invention, the bucket 5 comprises a device

  compaction 40 of the load in particular towards the bottom 6.

  This compacting device 40 consists of a first flap 41 articulated around a transverse axis 42 located in the upper part of the gland shield 18 and a second flap 43 articulated around a transverse axis 44 secured to the end upstream 45 from

roof 10 to the right of the opening 11.

  These flaps 41 and 43 are able to pivot about their respective axis 42, 44 between a first open position, as visible in FIG. 1, for loading the load and a second closed position (FIGS. 3 and 4). for compacting said load

  under the respective action of at least one jack.

  Each of these flaps 41, 43 are shaped so that in the open position the latter form a hopper for loading the load so as to guide the flow of

waste in the bucket.

  The first flap 41 advantageously consists of a transverse wall 44 having one of its ends articulated around the axis 42 and the other of its ends which is folded outwards at an angle of about 30 degrees from so as to obtain two faces 50, 51 for compacting the waste, when this flap 41 is in the position of

  closure, as shown in Figure 4.

  This first component 41 is controlled by means of two

  cylinders 52, 53 arranged longitudinally relative to the bucket.

  Each of these jacks 52, 53 consists of a body connected to the upper part of the gland shield 18 and a rod connected to the folded end of the transverse wall 44. The first flap 41 is also provided in the vicinity of the 'articulation 42 of a valve 60 -or freely articulated flap

  about a transverse axis 60a parallel to the articulation axis 42.

  This valve 60 extends vertically towards the bottom of the bucket in the open position of the first flap 41 and is intended to be pushed towards the front of the bucket by the waste so as to obstruct the space 62 formed between the articulation of the flap 41 and the gland shield 18 in order to avoid the waste being raised by said space 62 on the top of the flap during in particular a phase of

compaction of its waste.

  The second flap 43 comprises a first element 54 consisting of a transverse wall and a second element 55 also consisting of a transverse wall articulated around an axis A parallel to the axis 44 of the first element 54 and able to be foldable over

the latter 54.

  This first element 54 is mounted articulated around the transverse axis 44 and is able to move around this axis by means of two jacks 56 arranged on either side of the bucket, as visible in FIG. 8, and each having the end of the cylinder body secured to a side wall and the cylinder rod connected

  to one of the side edges of the first element 54.

  It will be noted that the second element is also able to take a first open position relative to the first element 54 and a second closed position in which the first and the second element are folded over one another, as visible on the FIGS. 3 and 4, for example by means of cylinders 57 arranged,

  as visible in FIGS. 1 to 8, between the two elements 54, 55.

  The operation of the compacting device of this

  The invention will now be described in relation to FIGS. 1 to 7.

  When collecting waste, by the vehicle shown in Figure 1, the operator chooses beforehand according to the size and shape of the container that he must unload in the bucket 5, to open the two flaps 41 and 43 at most as visible in FIG. 1 or at least leaving the second flap 43 in the closed position and placing the second element 55 of this second flap 43 in the open position, as visible in FIG. 2, thus providing with the first flap 41 a hopper so as to guide the flow of waste

in the bottom of the bucket.

  Then, by means of the lifting means 16, the operator lifts the container so as to present it in line with the opening 11 of the bucket. The opening of the container can be controlled by bringing, as shown in the embodiment described, a lever 70 integral with said container in contact with the end for example of the first flap 41, thus releasing the waste collected in

skip 5.

  The opening of flaps 41, 43 or 41, 55 in the form of a hopper advantageously makes it possible to prevent the waste from flowing out of the bucket, the latter being guided and retained by the flaps of

compaction.

  The container is then rested on the ground, by means of the lifting device 16. The operator by means of the control lever 33 locks the front of the bucket with the cradle, inserting the latches 31 into the orifices 31a, then controlling the closure of

  compaction flaps, as shown in Figure 3.

  A waste compacting cycle intended to reduce the volume of the latter, is then carried out by controlling the movement of the gland shield 18 by means of the jack 14 by longitudinal reciprocating movements in said bucket 5. During this movement the waste comes into contact with the valve 60 thus pushing the latter towards the gland shield 18 and obstructing

  consequently space 62.

  Advantageously, it will be noted that rollers 71 are provided at the end of the folded part of the first flap 41 so as to

  allow it to slide under the second flap 43.

  In addition, advantageously, it can be provided at the opposite end of the articulation 44 of the first element 54 of the second flap

  43 of the spurs 72 so as to retain the compacted waste.

  During this compacting operation, we understand all the advantage of the shape of the first flap 41 which has two compacting faces 50, 51 thus making it possible to push backwards from the

  bucket and towards the bottom 6 the waste.

  Once the compaction cycle has ended, the gland shield 18 is repositioned in its rest position in contact with the wall

  front 8 of the bucket 5, as shown in Figure 1.

  Advantageously, a removable or articulated transverse bar 80 about a vertical axis 81 secured to one of the side walls 7 is disposed substantially in the middle part of the bucket 5, so as to limit the return of the compacted waste towards the before the latter, in particular for waste of the plastic bottle type which has a strong elastic characteristic. This bar 80 is immobilized in transverse position by means of

  example of a hook 100, as visible in FIG. 8.

  When the bucket 5 is filled, the operator can go to a waste treatment area, where he will have to empty the contents of the bucket. This operation is carried out by locking the gland shield 18 with the bucket 5 by means of the control lever 33 thus engaging

  the latches 32 in the orifices 32a, as shown in FIG. 6.

  The operator opens the rear door 9 of the bucket 5 and controls the actuation of the jack 14 thus causing the pivoting of the bucket

  5 around the axis 13, as visible in FIG. 7.

  During this operation, the bar 80 is free to be able to pivot around its axis 81 thus allowing the release of the waste, so that in the final phase this bar is found along the wall

side 7 of the bucket 5.

  There is shown in Figures 9 to 12, a second embodiment of the waste compacting device, to simplify

  the description, the identical elements of the first embodiment

  will be designated by the same reference numbers.

  Unlike the first embodiment, the second compaction flap 43 has the general shape of any triangle T in longitudinal section thus defining two transverse walls 84, 85 which join at a joined end 83 forming the top

  of the triangle, that is to say the free end of the flap.

  The opposite end to the joining end 83 of one of these walls 84 is articulated around the transverse axis 44 while the end of the other wall 85 is connected at least to the rod of at least one jack 87. Preferably, the wall 85 of the second flap 43 is connected to two jacks 87 arranged symmetrically with respect to the axis

  longitudinal the bucket 5, as shown in FIG. 12.

  This second flap 43 is able to take three positions, respectively opening (Figure 9), closing (Figure 10) and

reduced opening (figure 11).

  The first compaction flap 41 may include perforations 90, shown in FIG. 12, allowing the operator to control the height of the waste in the bucket 5 or the emptying of the

container.

  According to a variant, the gland shield 18 includes openings 91 allowing the passage of longitudinal bars 92 fixed on the one hand to the bar 80 and on the other hand to the front wall 8 of the bucket by means of pins 93 for example These bars associated with the bar 80 advantageously make it possible to place the

  container to open it.

  i! In the downstream part of the bar 80, considering the figure, non-return bars 94 longitudinal of the waste are hingedly connected at one of their ends around a transverse axis 95 integral with the bar 80. These non-return bars 94 are intended to be lifted under the action of the waste introduced, up to

  their contacts in abutment against the roof.

  The non-return bars 94 can advantageously be replaced by a transverse flap articulated around a transverse axis secured to the side walls 7 of the bucket. This component is thus able to pivot under the action of the waste between at least two stops 99, shown in silhouette in FIG. 10, secured to the

walls 7.

  It will be noted that the jack 14, unlike the first embodiment, can be connected to the bottom 6 of the bucket and disposed substantially horizontally inside the latter as

visible in Figure 10.

  Advantageously, according to the variant described above, a telescopic jack, not shown, is arranged substantially vertically between the bottom of the bucket and the cradle 12 or chassis of the vehicle.

  so as to tilt the bucket around the axis 13.

  This embodiment thus makes it possible to move the gland shield 18 in the bucket and consequently the first compaction flap 41 during a tipping or tilting operation. There is shown in Figures 13 and 14, a variant of fixing the front of the bucket with the cradle 12, in which the fitting 15 the bucket consists of a pivot joint allowing

  vertical angular deflections of the bucket at an angle ct.

  This attachment of the bucket 5 advantageously allows flexibility

grab torturer.

  It will be noted that the locking means 30 are adapted and shaped so as to be fixed on the fitting 15, as visible in FIGS. 13 and 14, illustrating respectively the locking of the spoiler shield 18 with the bucket and the locking of the front of the

  bucket with chassis 2 or cradle 12.

  We understand from reading the above description of the two

  embodiments that the present invention allows to adapt to all kinds of household waste and all types of containers. In addition, by this waste compacting device according to the present invention, the bucket can accommodate a larger volume of waste, and makes it possible to compact it very

  fast, by simple and reliable means.

  Of course, the invention is not limited to the embodiments which have been described; one could on the contrary conceive various variants without departing from the scope of the invention. Thus, for example, the bucket can be mounted on a trailer or a vehicle.
