Description

The present invention relates to a container for holding or removing lumpy material, in particular solid, free-flowing heating material, such as pellets of wood, or grain or feed, wherein the container from substantially vertical peripheral boundary walls and optionally an upper Covering wall is provided and in the region of a particular tapered bottom an application device for removing the lumpy material from the container is provided, wherein the container consists of substantially vertical Umfangssbegrenzungnwänden and optionally an upper cover and in the region of a particular tapered bottom an application device for removing the lumpy material is provided from the container, wherein the bottom is made of a rigid, in particular metallic material, for example steel, and funnel from the outer peripheral wall regions or truncated pyramid substantially tapers to the center of the bottom of the container, and the peripheral boundary walls are at least partially made of a flexible material, and wherein the peripheral boundary walls at least partially adjustable in particular in their vertical dimension or height extension for adaptation in particular to different room heights.

An education of the above type is for example the GB-A 1 269 060 to extract, with the aim of such a container for transport to a position of comparatively reduced height while in the operating state a position of increased, but fixed height should be achievable.

Furthermore, the US-A 5,913,459 to take a container for receiving material, which has a discharge device in its bottom region, which, for example, followed by a screw conveyor.

In connection with heating systems, which are operated with solid, free-flowing heating material, it is for example also known to provide a storage space next to the heating system, in which such heating material, such as pellets made of wood, are collected. The supply of the heating material to the heating system or a boiler of such a heating system takes place for example via a suction line, as among others the AT-U 3734 , of the AT-B 405 875 or the EP-A 1 052 456 can be seen. A disadvantage of these known heating systems is in particular the fact that, for example, in a basement a separate space for the storage or recording of the heating material is provided and that with such suction pipes a proper dosing of the heating material is not readily possible.

Moreover, it is known to transport the heating material from a storage space to a heating system or to an intermediate container of such a heating system from such storage warehouses usually having a long length screws. A disadvantage of such embodiments is the fact that such screw conveyors usually extend over a very long length, whereby a very large mechanical effort for such screw conveyors is required.

In addition, it is for example from the AT-U 5275 known to provide reservoir, which serve for receiving the heating material, wherein the heating material is removed from such storage containers in turn via a suction line, with such Saugförderanlagen the above-mentioned disadvantages are connected. In the reservoir according to the AT-U 5275 is also aimed at providing a plurality of substantially rectangular sheet metal elements according to the desired size, these sheet metal elements being assembled using struts. For an adaptation to different room sizes or room heights, an adaptation can be provided only the dimensions of the different sheet metal elements or it must be provided or provided for an exact match a very large variety of different dimensions having elements, so that an excessive large storage and manufacturing costs associated with such a construction.

In connection with storage containers, for example for grain or feed constructions are also known in which flexible boundary walls, for example, as a bag-like silo, use, but generally in flowable or lumpy material in the event that even in the area of the floor flexible peripheral walls Limiting walls are provided, usually the problem of uneven distribution or collection of auszubringendem material results, so that the possibilities of proper application of the material are impaired or by deposition of auszubringendem Material result in an uneven spreading.

The present invention aims to develop a container of the type mentioned in that adaptation of the container in particular to different room heights is possible.

To solve these objects, a container of the type mentioned is essentially characterized in that the peripheral boundary walls are formed in a subsequent to the bottom portion of rigid, substantially plate-shaped boundary walls, to which in the vertical direction the adjustable in their vertical dimension or height extent sections connect the perimeter boundary walls.

The formation of the bottom of a rigid, in particular metallic material and the funnel-like or truncated conical taper substantially to the center of the bottom allow a reliable discharge of the material received in the container, without resulting in an undesirable accumulation of material in portions of the container, as for example must be feared in training the entire container with substantially flexible peripheral walls. In addition to the formation of the floor of a rigid, in particular metallic material, the peripheral boundary walls are at least partially made of flexible material in the height direction, so that the advantages of a flexible storage or a flexible container can be combined with a reliable deployment by the substantially rigid floor construction. At the same time allows the substantially rigid floor construction an application of the recorded or stored in the container material with the least possible friction losses.

Since the peripheral boundary walls are at least partially adjustable, in particular in their vertical dimension or height extent succeeds in a simple manner to particular room heights in particular, in which the container or reservoir to be provided or built, whereby the usability of the container taking into account the improved Ausbringens can be further increased.

Since such containers may need to accommodate large volumes and thus also great weight or to resist these, the invention proposes that the peripheral boundary walls are formed in a subsequent to the bottom portion of rigid, substantially plate-shaped boundary walls, which in the vertical direction in their vertical Dimension or height extension connect adjustable sections of the peripheral boundary walls. It may thus be provided a basic area of a substantially rigid container construction, in which it can be assumed that it can be used regardless of the room height in each case, with the exact adaptation to the dimensions of such rigid, substantially plate-shaped boundary walls connect again adjustable portions of the peripheral boundary walls, in particular made of flexible or fabric-like material.

For a particularly simple adaptability, in particular the height or generally the dimensions of such a container, is proposed according to a preferred embodiment that the at least partially formed of a flexible, in particular tissue-like material circumferential boundary walls are mounted or fixed to a height-adjustable frame construction. By providing perimeter confining walls which are at least partially made and adjustable from a flexible, especially fabric-like, material, by providing a single model or a very small number of different models of such perimeter walls corresponding to the spatial requirements, a precise match can be made, for example Room height can be made by a particular height-adjustable frame or scaffolding construction.

For a particularly simple adjustment and adaptation is proposed according to a further preferred embodiment, that the frame construction is formed by at least vertically telescoping struts.

For a proper and reliable spreading of the lumped material received in the container is proposed according to a further preferred embodiment that in the region of the recessed center of the bottom, in particular a sump of the container, the dispensing device is arranged, wherein it is also proposed that the dispensing device of a screw and / or a suction element is formed, as corresponds to a further preferred embodiment of the container according to the invention.

For a particularly simple and reliable determination, with which a support of possibly large Volumes or large weight is possible, it is proposed according to a further preferred embodiment that the particular flexible peripheral boundary walls on their facing the outside of the container surfaces fixing or receiving elements, such as tabs or eyes, for receiving struts, in particular in a substantially horizontal Direction extending struts, the frame structure have.

For a simple determination of the flexible peripheral boundary walls on the floor or rigid wall elements is proposed according to a further preferred embodiment that the flexible peripheral boundary walls are fixed by clamping element to the bottom and / or subsequent wall elements.

The portion of the peripheral boundary walls of flexible or fabric-like material may be formed in a simple manner substantially tubular and thus extend over the entire circumference in one piece and set on the receiving elements, such as tabs or eyes or clamping elements to the adjoining floor areas or frame construction become.

In Fig. 1 and 2 1 generally denotes a frame or framework construction of a container, the frame construction 1 consisting, for example, of four vertical struts 2 arranged at the corner points of a rectangle, which are connected by a plurality of substantially horizontally extending struts 3.

As in particular from Fig. 1 can be seen, the vertical struts 2 in the vertical direction telescopic or height adjustable, as indicated by the double arrow 4, wherein the individual sub-elements of the vertical struts with 2 'and 2 "are designated.

Out Fig. 1 is further seen that the bottom of the container consists of plate-shaped elements 5, which are made of a rigid, in particular metallic material, such as steel, wherein these plate-shaped Elements 5 open like a funnel or truncated pyramid to the center of the bottom or sump 6. In the area of the sump 6 there is arranged an application device, schematically designated 7, which is formed, for example, by a motor-driven worm or a suction element.

As in particular from Fig. 2 can be seen, for the peripheral boundary walls of the container in the vertical direction flexible, in particular made of tissue-like material bounding walls 8 are provided which are defined by loops or loops attachment elements 9 on the particular horizontal struts 3 of the frame structure 1.

Due to the height adjustability of the vertical struts 2 corresponding to the double arrow 4 can be due to the flexibility of the peripheral boundary walls 8, a corresponding adjustment at least in the height direction of in Fig. 1 and 2 achieved container to local conditions.

In Fig. 2 In addition, insertion for the male material or vent 10 and 11 are indicated. Furthermore, a corresponding cover may be provided on the upper side facing away from the bottom 5.
