Description

Title of the invention: Mobile extension skip

[0001] The invention relates to a skip comprising at least one movable extension.

[0002] TECHNOLOGICAL BACKGROUND OF THE INVENTION

[0003] Traditional tipping skips prove impractical when the contents of the skip body need to be emptied onto uneven terrain or terrain containing obstacles (such as power lines). Tilting the skip body can therefore be difficult or even impossible.

[0004] To overcome this drawback, a new type of skip, known as a "moving floor" skip, has been proposed. Such a skip comprises a chassis, a skip body mounted on the chassis, and a hinged door on the skip body to temporarily close off the open rear end. The skip also includes a conveyor belt on its floor that allows the product inside the skip to move within the skip body for loading and unloading.

[0005] In this way, it is no longer necessary to tilt the skip body to empty the contents: it is sufficient to simply activate the conveyor belt to discharge the contents of the skip through the open end. Such a skip is therefore more practical for emptying the contents, even on uneven terrain or terrain with obstacles.

[0006] SUBJECT OF THE INVENTION

[0007] One aim of the invention is to provide a more advanced skip. Summary of the invention

[0008] To this end, the invention relates to a tipper body comprising a chassis and a tipper body mounted on the chassis, the tipper body comprising a bottom extended by

[0009] at least two side sides, the skip comprising a roof covering at least part of the skip body, the skip further comprising at least one extension of the skip body which is movably mounted on the skip body.

[0010] In this way, it becomes possible to easily adjust the height of the skip.

[0011] Of course, for the purposes of this application, the terms "upper," "lower," "front," "rear," etc., must be understood in relation to the skip's operating position, that is, the position in which the skip rests on the ground over which it is intended to travel. The terms "front" and "rear" must therefore be understood in relation to the skip's operating position and the direction of travel of the skip on said ground when it is towed by a motor vehicle.

[0012] According to a particular embodiment, the extension slides on the body of the tipper.

[0013] According to a particular embodiment, the riser is a lateral riser of the skip body.

[0014] According to a particular embodiment, the extension is integral with the roof so that the movement of the extension causes the roof to slide relative to the body of the tipper.

[0015] According to a particular embodiment, the extension is an upper extension of a door closing one end of the skip body.

[0016] According to a particular embodiment, the upper extension is rotationally linked to the door at a first end and slides along the roof.

[0017] According to a particular embodiment, the extension is an extension of a front side of the tipper body.

[0018] According to a particular embodiment, the extension slides along the front side and is rotationally linked to lateral extensions of the tipper body.

[0019] According to a particular embodiment, the skip includes a door closing one end of the skip body, the door being equipped in the lower part with a sealing gasket compressed between the door and the skip body when the door is closed.

[0020] According to a particular embodiment, the skip includes a door closing one end of the skip body, the door being curved outwards from the skip body.

[0021] According to a particular embodiment, the skip includes a suction module.

[0022] According to a particular embodiment, the riser is a lateral riser of a door closing one end of the skip body.

[0023] Other features and advantages of the invention will become apparent from the following description of a particular, non-limiting embodiment of the invention. DESCRIPTION OF FIGURES

[0029] DETAILED DESCRIPTION OF A PARTICULAR EMBODIMENT OF THE INVENTION

[0030] With reference to [Fig. 1], the tipper body according to a particular embodiment of the invention, generally designated as 1, comprises a chassis 2 and a tipper body 3 which is mounted on the chassis 2 and which extends longitudinally along an X axis. The tipper 1 is here connected to a motorized vehicle such as a tractor (not shown here).

[0031] In particular, the tipper body 3 has a horizontal bottom 6 extended laterally by two vertical side panels, namely a left side panel 4 and a right side panel 5 (when the tractor is being driven). However, the tipper body 3 is open at its rear. The tipper body 3 also includes a conveyor belt 7 arranged on the bottom 6 of the tipper body 3, ensuring the movement of the product contained in the tipper 1 towards the rear or front of the tipper body 3. The tipper 1 is thus said to have a "moving floor".

[0032] The front part of the skip body 3 is closed here by a suction module 8 allowing the suction of a product (such as crop or shredding waste of plant type or straw for example or fodder or in general any other product that can be suctioned).

[0033] The suction module 8 includes 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.

[0034] Furthermore, the front part of the skip body 3 has a front side 11 arranged between the suction module 8 and the conveyor belt 7. The front side 11 is typically inclined relative to the side sides 4, 5 and extends from the bottom 6 towards the suction module 8.

[0035] The suction module 8 is thus arranged in the skip 1 between the front side 11 and an attachment 12 of the skip 1 to the motorized vehicle.

[0036] Preferably, the suction module 8 is arranged in a removable manner on the chassis 2 so as to allow the skip 1 to be equipped with another module if necessary or to allow the skip 1 to be used without a module.

[0037] Furthermore, the rear part of the tipper body 3, which is open because it lacks a 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 tipper body 3 and an open position where it allows access to the inside of the tipper 1 through said open rear part.

[0038] In order to increase the volume of the skip body, the door 12 is not flat.

[0039] Said door 12 here more particularly comprises a rear base 13 supported by a left side panel 14 and a right side panel, which extend longitudinally parallel to the X axis, i.e. parallel to the direction of the side sides 4, 5 of the tipper body 3. The rear base 13 is curved outwards from the tipper body 3 to allow an increase in the volume of the tipper body 3. The two side panels 14 and the rear base 13 are preferably of one piece.

[0040] The left side panel 14 is thus mounted pivoting about an axis Y (orthogonal to the axis X) on the external face of the left side panel 4 of the tipper body 3, and, similarly, the right side panel is mounted pivoting about the axis Y on the external face of the right side panel 5 of the tipper body 3.

[0041] For this purpose, the skip 1 here includes means for actuating the door 12. These means thus allow a 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 over the skip body 3.

[0042] In particular, the actuation means comprise a first left-hand cylinder 15 associated with the left side 4 and the left panel 14, and a second right-hand cylinder associated with the right side and the right panel. Typically, each cylinder has its body fixed to the associated side and its rod fixed to the associated panel. The two cylinders are actuated simultaneously such 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.

[0043] Preferably, to ensure a hermetic seal of the tipper body 3, the door 12 is provided at its lower end with a seal 25 which is compressed between the door 12 and the base 6 when the door 12 is in the closed position. The seal 25 is, for example, made of an elastically deformable material and preferably of natural or synthetic rubber. The seal 25 is supported here by the lower end of the rear base 13 of the door 12. The seal 25 thus extends longitudinally substantially parallel to the Y-axis. The seal 25 is generally shaped into a cylinder.

[0044] The skip body 3 also includes 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. However, an air exhaust outlet from the suction module 10 passes through the roof 16.

[0045] The roof 16 is optionally foldable.

[0046] Furthermore, the skip 1 includes at least one extension of the skip body 3.

[0047] In the present case, the skip 1 has several extensions to increase the overall 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.

[0048] Thus, the skip 1 comprises two lateral extensions 17, 18 left and right extending respectively in line with the side walls 4, 5 left and right. The skip 1 further comprises a front extension 19 extending in line with the front wall 11 between the suction module 8 and the interior of the skip body 3.

[0049] The skip 1 also includes at least one door extension. There are three door extensions here: 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 may then include a roof above which the upper extension 20 is arranged or the door 12 may then be without a roof and include only the upper extension 20 which then serves both as an extension and as a roof for the door 12).

[0050] The risers, respectively 21, 22, are integral with the lateral risers, respectively 17, 18. The said risers 21, 22 are however considered as door risers 12 because in the closed position of the door 12 (as seen in [Fig.2a]), the risers 21, 22 extend in line with the panels 14 of the door 12. The risers 21, 22 are arranged inside the panels 14 so that the door 12 pivots around the Y axis external to the two risers 21, 22.

[0051] In order to ensure that the door 12 can pivot despite the presence of the risers, the upper riser 20 slides along the roof 16.

[0052] Furthermore, the lower end of the upper extension 20 is pivotally mounted on the door 12. More specifically, the lower end of the upper extension 20 is pivotally mounted at the upper end of the rear base 13 between the side panels 14 about an axis Y' parallel to the Y axis. To allow sufficient clearance, the door 12 is shaped so that the Y axis is positioned in front of the Y' axis when the door is in the closed position. The door 12 is also shaped so that the Y axis and the Y' axis are substantially at the same height from the bottom 6 when the door is in the closed position.

[0053] In this way, as illustrated in [Fig.2a], in the closed position, the door 12 obstructs the rear part of the tipper 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.

[0054] When the jacks are actuated, as illustrated in [Fig.2b], the door 12 rises progressively so as to pivot around the Y axis causing a progressive pivoting of the upper extension 20 around the Y' axis guided in its pivoting by its sliding along the roof 16.

[0055] This ensures that the door 12 can be opened 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.

[0056] Correspondingly, as more visible in [Fig.3], the front riser 19 is mounted to slide vis-à-vis the front side 11.

[0057] Furthermore, the upper end of the front extension 19 is pivotally mounted on the tipper body 3 and / or the suction module 8 and / or the side extensions 17, 18. More specifically here, the upper end of the front extension 19 is mounted pivoting at the level of lateral risers 17, 18 around a Y axis” parallel to the Y axis.

[0058] The front extension 19 is thus movable inside the body of the tipper 3.

[0059] Advantageously, the side extensions 17, 18 are mounted to slide relative to the left and right sides 4, 5 of the tipper body 3. These extensions 17, 18 are 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 should be noted that, because the extensions 21, 22 are integral with the side extensions 17, 18, the extensions 21, 22 are also mounted to slide relative to the left and right sides 4, 5 of the tipper body 3.

[0060] To this end, each side extension 17, 18 and each extension 21, 22 is slidably mounted along the associated side 4, 5 between a raised position in which it extends at least partially in line with the associated side above said side and a lowered position in which it extends at least partially outside the tipper body 3 along the associated side. Each side extension 17, 18 and each extension 21, 22 is thus slidably mounted along the associated side along a translational axis Z (orthogonal to the X axis and orthogonal to the Y axis). The side extensions 17, 18 and the extensions 21, 22 are therefore lowered or raised according to a vertical movement.

[0061] The skip 1 includes means for actuating the side extensions 17, 18 and the extensions 21, 22.

[0062] In particular, the actuation means here comprise at least one left-hand cylinder associated with the left side 4 and the left extension 17, and one right-hand cylinder associated with the right side 5 and the right extension 18. Typically, each cylinder has its body fixed to the associated side, and each rod is fixed to the associated extension. The cylinders are actuated simultaneously such that their extension causes the side extensions 17, 18 and the extensions 21, 22 to move from the lower position to the upper position, and their retraction causes the side extensions 17, 18 and the extensions 21, 22 to move from the upper position to the lower position.

[0063] According to a particular embodiment, each side extension 17, 18 is made up of as many elements as the associated side panel 4, 5 has panels. Each element slides in guides formed at the level of posts 23 (only one being referenced here) arranged between two consecutive panels of a panel of the associated side panel, 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 extension 17, 18 is in this case a single piece.

[0064] The extensions 21, 22 are each made up of a single element. Each element slides along 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 extension.

[0065] Preferably, the side extensions 17, 18 and the extensions 21, 22 are integral with the roof 16, which can therefore also be lowered or raised by means of the side extensions 17, 18 and the extensions 21, 22. The side extensions 17, 18, the extensions 21, 22 and the roof 16 thus jointly form a parallelepiped open to the bottom of the tipper body 3.

[0066] Therefore, when the skip 1 begins to fill up, it is possible to lower the roof 16 and the side extensions 17, 18 and extensions 21, 22 to compress the product through the roof 16 before raising everything again. This operation compresses the product in the skip 1 to increase the product storage volume.

[0067] As for the upper extension 20, it pivots around the axis Y' to follow the lowering or raising of the side extensions 17, 18 and the extensions 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 axis Y and a point on the axis Y' (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 extensions 17, 18 and the extensions 21, 22.

[0068] The upper extension 20 thus advantageously allows the door 12 to be opened and closed regardless of the relative position of the side extensions 17, 18 and the extensions 21, 22 with respect to the body of the tipper 3.

[0069] Similarly, the front extension 19 follows the movement of the roof 16 and is therefore also lowered or raised with the side extensions 17, 18 (the front extension 19 then sliding along the front side 11 to lower or raise itself). The front extension 19, for its part, ensures a good closure of the front of the tipper body 3 regardless of the relative position of the side extensions 17, 18 with respect to the tipper body.

[0070] In particular, the suction module 8 has at least one retractable portion enabling it to follow the movement of the roof 16, the roof 16 covering the suction module 8. Typically, the suction column 9 is retractable here (the lower portion of the suction column carrying pumping means remaining fixed relative to the body of the skip 3).

[0071] Of course the invention is not limited to the embodiment described and alternative embodiments can be made without departing from the scope of the invention as defined by the claims.

[0072] 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 chips...)). or, alternatively or in addition, include one or more other modules such as a module for collecting fodder for example.

[0073] Although here the skip is attached to a motorized vehicle, the skip can be directly motorized, with a driving position then being arranged at the front of the skip.

[0074] Furthermore, the door may be of a different shape than indicated. In particular, the door may be flat.

[0075] A different number of extensions than specified may be used. For example, the side extensions may be fixed relative to the chassis, while the door roof extension and / or the front extension may be movable. Conversely, the side extensions may be movable while the door roof extension and / or the front extension are fixed. In the case of side extensions for the door, these may be fixed or movable independently of the extensions on the sides of the tipper body.

[0076] The actuation means may also differ from those indicated. For example, the door may be actuated using a single cylinder. Similarly, the lowering and raising of the side extensions may be controlled by a different number of cylinders. The front extension and / or the upper extension may also be individually equipped with means for its own actuating operation.

[0077] 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. Similarly, the side extensions of the tipper body can slide inside the side panels. The side extensions of the door can also be fixed.
