Description

MOBILE ELEVATED BUCKET

The invention relates to a skip comprising at least one mobile extension.

TECHNOLOGICAL BACKGROUND OF THE INVENTION

Traditional tipper body skips prove to be impractical when the contents of the tipper body must be dumped on uneven ground or with obstacles (electrical wires for example). Tilting the tipper body is therefore sometimes difficult or even impossible.

To overcome this drawback, a new type of skip called “moving floor” has been proposed. Such a dump body comprises a frame, a dump body mounted on the frame and a door pivotally mounted on the dump body to temporarily close the rear open end thereof. The skip also includes a belt arranged on the bottom of the skip allowing movement of the product present in the skip inside the skip body to be able to load or unload the product.

In this way, it is no longer necessary to tilt the body of the skip to dump the contents of the skip: it is sufficient to simply activate the belt to evacuate the contents of the skip out of the skip by the open end. Such a dumpster is therefore more practical for dumping the contents of the dumpster even on uneven ground or with obstacles.

OBJECT OF THE INVENTION

An object of the invention is to provide a more sophisticated bucket.

To this end, the subject of the invention is a skip comprising a chassis and a skip body mounted on the chassis, the skip body comprising a bottom extended by

at least two lateral flanks, the skip comprising a roof at least partially covering the skip body, the skip further comprising at least one extension of the skip body which is movably mounted on the skip body.

In this way, it is possible to simply adapt the height of the skip.

Of course, throughout this application, the terms "upper", "lower", "front", "rear" ... must be understood according to the position in service of the bucket, that is to say the position in which the bucket rests on the ground on which it is intended to roll. The terms "front", "rear" must therefore be understood according to the position in service of the tipper and the direction of advancement of the tipper on said ground when it is towed by a motorized vehicle.

According to a particular embodiment, the extension slides on the tipper body.

According to a particular embodiment, the riser is a side riser of the tipper body.

According to a particular embodiment, the riser is secured to the roof so that the movement of the riser causes the roof to slide relative to the tipper body.

According to a particular embodiment, the extension is an upper extension of a door closing one end of the tipper body.

According to a particular embodiment, the upper riser is rotationally connected to the door at a first end and slides along the roof.

According to a particular embodiment, the extension is an extension of a front side of the tipper body.

According to a particular embodiment, the collar slides along the front side and is rotatably connected to side collars of the tipper body.

According to a particular embodiment, the skip comprises a door closing one end of the skip body, the door being equipped in the lower part with a compressed seal between the door and the skip body when the door is closed.

According to a particular embodiment, the skip comprises a door closing one end of the skip body, the door being curved towards the outside of the skip body.

According to a particular embodiment, the skip comprises a suction module.

According to a particular embodiment, the extension is a side extension of a door closing one end of the tipper body.

Other characteristics and advantages of the invention will become apparent on reading the following description of a particular non-limiting embodiment of the invention.

DETAILED DESCRIPTION OF A PARTICULAR EMBODIMENT OF THE INVENTION

With reference to FIG. 1, the skip according to a particular embodiment of the invention, generally designated at 1, comprises a frame 2 and a skip body 3 which is mounted on the frame 2 and which extends longitudinally along a axis X. The bucket 1 is here connected to a motorized vehicle such as a tractor (not shown here).

In particular, the skip body 3 comprises a horizontal bottom 6 extended laterally by two vertical side flanks, ie a left side flank 4 and a right side flank 5 (when driving the tractor). However, the skip body 3 is open at its rear part. The skip body 3 also comprises a belt 7 arranged on the bottom 6 of the skip body 3 ensuring movement of the product contained in the skip 1 towards the rear or the front of the skip body 3. The skip 1 is thus called "moving floor".

The front part of the skip body 3 is closed here by a suction module 8 making it possible to suck up a product (such as crop or crushing waste of the plant or straw type, for example, or fodder or generally any other product that can be vacuumed).

The suction module 8 comprises for this purpose a suction column 9 and an expulsion portion 10 which is angled to facilitate the discharge of a product from the ground into the body of the skip 3.

Furthermore, the front part of the skip body 3 comprises a front flank 11 arranged between the suction module 8 and the belt 7. The front flank 11 is typically inclined vis-à-vis the side flanks 4, 5 and extends from the bottom 6 towards the suction module 8.

The suction module 8 is thus arranged in the bucket 1 between the front side 11 and an attachment 12 of the bucket 1 to the motor vehicle.

Preferably, the suction module 8 is arranged in a removable manner on the frame 2 in order to be able to allow the bucket 1 to be equipped if necessary with another module or to be able to use the bucket 1 without a module.

Furthermore, the rear part of the skip body 3, which is open because it has no fixed rear side, is in fact closed by a pivoting door 12 which is movable between a closed position where it covers the open rear part of the skip body 3 and an open position where it allows access to the interior of the bucket 1 through said open rear part.

In order to increase the volume of the tipper body, door 12 is not flat.

Said door 12 comprises here more particularly a rear base 13 carried by a left side panel 14 and a right side panel, which extend longitudinally parallel to the axis X, that is to say parallel to the direction of the side flanks 4, 5 of the skip body 3. The rear base 13 is itself curved towards the outside of the skip body 3 in order to allow an increase in the volume of the skip body 3. The two side panels 14 and the rear base 13 are preferably in one piece.

The left side panel 14 is thus pivotally mounted along a Y axis (orthogonal to the X axis) on the outer face of the left side flank 4 of the skip body 3, and, similarly, the right side panel is pivotally mounted along the Y axis on the outer face of the right side flank 5 of the tipper body 3.

To this end, the skip 1 here comprises means for actuating the door 12. Said means thus allow rotation of the door 12 between the closed position in which the door obstructs the rear part of the skip body 3 and the open position in which the door 12 releases the rear part by extending at least partly above the skip body 3.

In particular, the actuating means comprise a first left cylinder 15 associated with the left side 4 and the left panel 14 and a second right cylinder associated with the right side and the right panel. Typically, each cylinder has its body integral with the associated sidewall and its rod integral with the associated panel. The two jacks are actuated at the same time so that their extension causes the door 12 to move from the closed position to the open position and their retraction causes the door 12 to move from the open position to the closed position.

Preferably, to ensure hermetic closure of the skip body 3, the door 12 is provided in the lower part with a seal 25 which is compressed between the door 12 and the bottom 6 when the door 12 is in the closed position. The seal 25 is for example made of elastically deformable material and preferably of natural or synthetic rubber. The seal 25 is here carried by the lower end of the rear base 13 of the door 12. The seal 25 thus extends longitudinally substantially parallel to the axis Y. The seal 25 is generally shaped like a cylinder.

The skip body 3 also comprises a roof 16 covering at least part of the skip body 3. In the present case, the roof 16 is arranged to extend from the door 12 to the suction module 10. A air exhaust outlet of the suction module 10, however, here passes through the roof 16.

The roof 16 is optionally collapsible.

Furthermore, the skip 1 comprises at least one extension of the skip body 3.

In the present case, the skip 1 comprises several extensions to increase the general volume of the skip body 3. Preferably, all or part of the extensions of the skip 1 are removable. Each extension is also flat and made up of one or more elements.

Thus, the bucket 1 has two side extensions 17, 18 left and right extending respectively in the extension of the side flanks 4, 5 left and right. The skip 1 further comprises a front extension 19 extending in the extension of the front side 11 between the suction module 8 and the interior of the skip body 3.

The skip 1 also includes at least one door extension. The door extensions are here three in number: namely two side extensions 21, 22 left and right and an upper extension 20 serving as a roof for the door 12 (the door 12 can then comprise a roof above which is arranged the upper extension 20 or the door 12 can then be devoid of a roof and only include the upper extension 20 which then serves both as an extension and as a roof for the door 12).

The extensions, respectively 21, 22, are integral with the side extensions, respectively 17, 18. Said extensions 21, 22 are however considered as door extensions 12 because in the closed position of the door 12 (as shown in FIG. 2a), the collars 21, 22 extend in the extension of the panels 14 of the door 12. The collars 21, 22 are arranged inside the panels 14 so that the door 12 pivots around the axis Y externally to the two extensions 21, 22.

In order to ensure that the door 12 pivots despite the presence of the extensions, the upper extension 20 slides along the roof 16.

Furthermore, the lower end of the upper riser 20 is pivotally mounted on the door 12. More particularly here, the lower end of the upper riser 20 is pivotally mounted at the upper end of the rear base 13 between the side panels 14 around an axis Y' parallel to the axis Y. In order to have sufficient travel, the door 12 is shaped so that the axis Y is arranged in front of the axis Y' when the door is in the closed position. The door 12 is also arranged so that the Y axis and the Y' axis are substantially at the same height of the bottom 6 when the door is in the closed position.

In this way, as shown in Figure 2a, in the closed position, the door 12 obstructs the rear part of the skip body 3, the upper extension 20 covering the door 12 extending from the upper end of the rear base 13 to above the rear end of the roof 16.

When the jacks are actuated, as illustrated in FIG. 2b, the door 12 gradually rises so as to pivot around the Y axis causing a progressive pivoting of the upper collar 20 around the Y' axis guided in its pivoting by its sliding along the roof 16.

This ensures an opening of the door 12 despite the presence of the extensions of the tipper body 3 and in particular the side extensions 17, 18 and the side extensions 21, 22.

Correspondingly, as more visible in Figure 3, the front riser 19 is slidably mounted vis-à-vis the front side 11.

Furthermore, the upper end of the front riser 19 is pivotally mounted on the skip body 3 and/or the suction module 8 and/or the side risers 17, 18. More particularly here, the upper end of the front riser 19 is pivotally mounted at the side risers 17, 18 around an axis Y'' parallel to the axis Y.

The front riser 19 is thus movable inside the tipper body 3.

Advantageously, the side extensions 17, 18 are slidably mounted vis-à-vis the left and right sides 4, 5 of the tipper body 3. These extensions 17, 18 are here all of the same height. Preferably, the side extensions 21, 22 of the door 12 are also of the same height as the side extensions 17, 18 of the tipper body 3. It is noted that the fact that the extensions 21, 22 are integral with the side extensions 17 , 18, the extensions 21, 22 are also slidably mounted vis-à-vis the left and right sides 4, 5 of the tipper body 3.

To this end, each side riser 17, 18 and each riser 21, 22 is slidably mounted along the associated sidewall 4, 5 between a high position in which it extends at least partly in the extension of the associated sidewall above of said flank and a low position in which it extends at least partly outside the skip body 3 along the associated flank. Each side riser 17, 18 and each riser 21, 22 is thus mounted to slide along the associated side along a translation axis Z (orthogonal to the X axis and orthogonal to the Y axis). The side risers 17, 18 and the risers 21, 22 are therefore lowered or raised according to a vertical movement.

The bucket 1 comprises means for actuating the side extensions 17, 18 and the extensions 21, 22.

In particular, the actuating means here comprise at least one left jack associated with the left side 4 and with the left riser 17 and a right jack associated with the right side 5 and with the right riser 18. Typically each jack has its integral body of the associated sidewall and each rod is integral with the associated riser. The jacks are actuated at the same time so that their extension causes the side risers 17, 18 and the risers 21, 22 to move from the low position to the high position and their retraction causes the side risers 17, 18 and the risers to move. risers 21, 22 from the high position to the low position.

According to a particular embodiment, each side riser 17, 18 is made up of as many elements as the associated side wall 4, 5 has panels. Each element thus slides in slides provided at the level of posts 23 (only one being referenced here) arranged between two consecutive panels of a panel of the associated side, a jack 24 (only one being referenced here) being associated with each post and with a given element. It should be noted that although made up of several elements, each side riser 17, 18 is here in one piece.

The extensions 21, 22 are here each made up of a single element. Each element thus slides at the level of the post 23 arranged at the end of the tipper body 3 and is associated with a cylinder 24 (each element being associated with its own cylinder or being associated with the cylinder of the juxtaposed element of the associated side riser.

Preferably, the side risers 17, 18 and the risers 21, 22 are integral with the roof 16 which can therefore also be lowered or raised via the side risers 17, 18 and the risers 21, 22. The side risers 17, 18, the extensions 21, 22 and the roof 16 thus together form a parallelepiped open to the bottom of the tipper body 3.

Therefore, when the bucket 1 begins to be full, it is possible to order a lowering of the roof 16 and the side risers 17, 18 and the risers 21, 22 to crush the product through the roof 16 before raising the whole thing. This operation makes it possible to compress the product present in the bucket 1 to gain in product storage volume.

As for the upper collar 20, it pivots around the Y' axis to follow the lowering or raising of the lateral collars 17, 18 and the collars 21, 22; the upper extension sliding simultaneously along the roof 16. For this purpose, the door 12 is shaped so that the distance separating a point on the Y axis and a point on the Y 'axis (the two points belonging to the same plane which is orthogonal to the two axes Y and Y') is equal to or greater than the height of the side risers 17, 18 and the risers 21, 22.

The upper collar 20 thus advantageously allows the door 12 to be opened and closed regardless of the relative position of the side collars 17, 18 and the collars 21, 22 with respect to the tipper body 3.

In the same way, the front riser 19 follows the movement of the roof 16 and is therefore also lowered or raised with the side risers 17, 18 (the front riser 19 then slides along the front side 11 to lower or rise). The front riser 19 ensures for its part a good closure of the front of the tipper body 3 regardless of the relative position of the side risers 17, 18 vis-à-vis the tipper body.

In particular, the suction module 8 comprises at least one retractable portion making it possible to follow the movement of the roof 16, the roof 16 covering the suction module 8. Typically, the suction column 9 is here retractable (the portion lower part of the suction column carrying pumping means remaining fixed relative to the skip body 3).

Of course, the invention is not limited to the embodiment described and variant embodiments can be added thereto without departing from the scope of the invention as defined by the claims.

Thus, although here the skip is equipped with a suction module, the skip may not include a module (the skip may for example simply be used to transport a bulk product (manure, fodder, straw, pallets, wood …)) or, alternatively or in addition, include one or more other modules such as a module for collecting fodder for example.

Although here the tipper is attached to a motorized vehicle, the tipper can be directly motorized, a driving position then being arranged at the front of the tipper.

In addition, the door may be of a different shape than what has been indicated. In particular, the door may be flat.

A different number of extensions than indicated may be used. For example, the side risers may be fixed relative to the chassis, the roof riser of the door and/or the front riser being mobile. Conversely, the side extensions may be movable and the roof extension of the door and/or the front extension may be fixed. In the case of side extensions of the door, these may be fixed or may be movable independently of the extensions of the sides of the tipper body.

The actuating means may also be different from what has been indicated. The door can thus be operated using a single cylinder. Similarly, the lowering and raising of the side extensions can be done using a different number of cylinders. The front riser and/or the upper riser may also personally be provided with means for its own actuation.

Although here the roof extension slides on the roof, the roof extension can slide directly on the side extensions of the tipper body or inside the tipper body. In the same way, the side extensions of the tipper body can slide inside the side flanks. The side extensions of the door can also be fixed.
