Description

AT 401 916 B

The invention relates to a silicon unit for pourable or flowable goods, such as mortar, plasters, adhesives, etc.

The silos commonly used so far have such large dimensions that they can only be transported by means of special vehicles and set up on site. Special vehicles are also required for the possible addition or refill of the silos, taking into account the contents to be filled. Both the transportation and installation as well as the subsequent filling of these silos can only be justified from a cost point of view if correspondingly large quantities of material are processed at the installation site. (See for example DE 33 22 698 A1; DE 39 34 996 A1; DE 38 16 810 A1)

However, if only small quantities of filling material are required and processed, such as for single-family houses, renovation work, conversions, etc. the installation of a conventional silo is unprofitable simply because a special vehicle is required to transport and set it up as well as to transport it away.

Furthermore, a small container for bulk goods, etc. with a closable filling opening on the upper side and a closable outlet opening on the lower side with a capacity of 1 to 3m! known. A cube-shaped or cuboid-shaped container of the small container sits, for example, on a separate support frame corresponding to the plan of the container and is thereby held at a certain height above the floor. Since the container and the support frame are separate units, these two units can be parked next to each other on the loading surface of a loading crane truck for transport on the road, for example. The support frame is then first unloaded at the construction site and then the container filled with the material to be processed is placed on it (DE-GM 80 14 246).

Another known silo for transporting bulk material or the like has a container arranged on a support frame with an upper closure lid. The container consists of two horizontally divided, superimposed partial bodies, of which the respective upper partial body has a circumferential, downwardly open chamber at the lower end, into which the lower partial body, which has an outlet funnel, projects with its upper end. The two partial bodies can be detachably connected by means of closure elements and can be pushed together by rotating the respective upper container by 180 'about its horizontal axis, since the inner dimensions of the upper partial body are larger than the outer dimensions of the partial body located underneath.

Due to the proposed division of the container into two, the space requirement of the container in the empty state is reduced to half, which is advantageous both during transport and during storage. For use on the construction site, either a silo container, which has already been filled with bulk goods or the like and which is previously composed of the two partial bodies, can be placed as a whole on a previously removed supporting frame, or the lower partial body first placed over for transport Part body on the support frame and then the upper part body is placed on the lower part body; the two partial bodies are secured to one another and to the supporting frame by means of the tension locks. Then the silo container formed from the part bodies must be filled with the bulk material to be processed or the like on site.

The object of the invention is therefore a silo unit which can be transported and set up, for example, by means of a loading crane truck, for pourable or flowable goods of any kind, such as mortar, plasters, adhesives and the like. to create, the capacity in the range of 1 to about 6m3 can be variably adapted to the respective material requirements at any time. According to the invention, this is achieved in a silo unit according to claim 1 by the features in the characterizing part. Advantageous further developments are the subject of the claims which are directly or indirectly related to claim 1.

According to the invention, such a silo unit consists not only of an underframe that is always required, but also of at least two, but a maximum of four to five, identically constructed silo containers, each with a capacity of 1 to 1.2 m3, so that in a silo unit according to the invention a material quantity of approximately 1 to a maximum about 7t is to be accommodated.

The required number of identically constructed silo containers, which in principle can be used as often as desired and are already filled with the desired pourable or flowable material, is loaded, for example, by means of a conventional loading crane vehicle that is already available in the building materials trade and transported to the processing point. The silo containers are designed so that they can be placed on top of one another by means of the loading crane vehicle so that the filling opening of the respectively lower silo container is located vertically below the outlet opening of the silo container arranged above it. The stacked identical silo containers are connected to each other as well as to the base and secured accordingly. 2nd

AT 40t 916 B

If, for example, a forklift vehicle is available at the processing point or a crane is installed, the individual filled container can also be transported by truck without a loading crane. No special silo vehicles are required to transport, set up and collect the silo containers according to the invention.

Furthermore, the silo containers can be equipped so that machine processing is also possible. In addition, a machine part can already be completely assembled on the base frame, so that the assembly effort on site is thus eliminated. On top of that, the base frame can be easily converted to the different machine part designs.

Preferably, the silo containers, which have the ISO dimensions of 1200mm in width, depth and height, are each designed for a capacity of about 1 to 1.2m3, which ensures that with a conventional loading crane vehicle a filled silo container whose total weight is in is of the order of magnitude of approximately 1.5 t to 2 t, can easily be lifted onto the loading area and set down again on site or placed on top of a previously unloaded silo container. Such a silo unit with at least one to four, at most five silo containers can also be replaced without difficulty on small and spatially limited construction sites.

Thus, the invention advantageously creates a silo unit that can be adapted to the respective requirements in terms of its capacity, which requires considerably lower investment costs than a large silo, and which thus can be transported inexpensively in the form of the structurally identical silo containers without the aid of special vehicles and unloaded and unloaded at the processing point Can be put together on top of each other. It is also possible to replace empty silo containers with filled silo containers, whereby the loading crane vehicle used for transporting and setting up the silo unit can also be used for this purpose.

It is possible to fill the individual silo containers at the wholesaler or at the manufacturer using the large mother silos available there, which keeps transport costs low. In addition, there are no breakage or shrinkage costs or moisture damage compared to sack material and therefore no pollution overall. Furthermore, the respective fill level of a silo container can be read off from a sight glass, so that so-called reweighing can be carried out on the basis of the fill level.

In particular, there are also no costs, for example for sack material and / or shrink film, so that not only is the forthcoming packaging ordinance complied with, but because the packaging is omitted, the use and use of the silo unit according to the invention is also extremely environmentally friendly. Furthermore, silo containers that are not required can easily be stacked outdoors, so that only very low costs are incurred for storage.

The invention is explained in detail below with reference to a preferred embodiment with reference to the attached drawings. Show it:

The schematic representation in FIG. 1 shows a silo unit, designated in its entirety by 1, in which two silo containers 10i and IO2 of identical construction are arranged on a base frame 2 one above the other and are secured to one another in a manner described later. The other 3

Parts of the structurally identical silo containers 10i and IO2 corresponding to AT 401 916 B are identified with the same reference numerals but with different indices 1 and 2, respectively. Two or three further silo containers 103 to 10s can also be placed on the silo container IO2 and secured to one another.

Each silo container 10, which is approximately square in plan view, has four lateral support supports 11 at the corners, at the upper ends of which a closed cover 12 stiffened laterally with a centrally arranged, closable filling opening 120 with an upwardly projecting extension 121 are attached, while at the lower ends of the support supports 11 there is a frame 13 firmly connected to them with stiffeners (shown in more detail) and with a closable outlet opening arranged vertically below the filling opening 120. In the upper area of the four lateral support brackets 11 are attached to these side plates 111, which merge in the lower area of the silo container 10 into a downward, conical funnel 15 which ends at the outlet opening 131 or merges into this.

To guide and secure the stacked silo containers 10i and IO2, extend the four side supports 111 and 112 via the top cover 12? or 122 protruding angle iron 112i or 1122 b2w. Angle iron 112 'provided on the base 2. To secure the stacked silo containers 10i and IO2, as can be seen from the enlarged schematic illustration in FIG. 4, a closure cover 132 of the outlet opening 131 is connected to a through shaft 133 which is mounted outside the outlet opening 131 on the top of receptacles 130 . In FIGS. 1 and 2a, the shaft 133 merges into an extension 133 ′ on the left-hand side, which in FIGS. 1 and 2a extends perpendicularly to the horizontally arranged shaft 133.

Furthermore, two hooks 134 projecting vertically downwards in FIGS. 1 and 2a are provided outside the outlet opening with the shaft 133, to which two eyelets 125 are assigned in addition to the filling opening 120 formed in the upper cover 12. In FIGS. 1 and 2a, the hooks 1342 of, for example, the silo container IO2 with the silo container 10? provided eyelets 125? engaged. As a result, the upper silo container IO2 is then secured to the silo container 10i arranged below it.

The same securing is also provided between the lower silo container 10i and the base frame 2 arranged underneath, on the upper frame 20 of which corresponding eyelets 125 'are attached. As can be seen from the illustrations in FIGS. 2a and 4, is in the secured position, in which, for example, the hook 1342 with the eyelet 125? is engaged, the closure lid 1322 of the silo container IO2 in the open vertical position shown in dashed lines in FIGS. 2a and 4. In Figure 4, the closed position of the lid 1322 and the corresponding position of the hook 1342, in which it is disengaged from the eye 125i, are each shown in dash-dotted lines.

The hook 1342 is brought into engagement with the eyelet 125i in that the extension 133 'of the shaft 133, with which the hooks 134 are firmly connected, is brought up into the position shown, for example, in FIGS. 1 and 2a. The extension 133 ′ and thus the shaft 133 and the hooks 134 fastened to it are secured by a hook 3 which is pivotably held on the outside of the funnel 15. Here, the hook 3 is then in the position shown in broken lines in FIG. Here, the hook 3 engages behind the extension 133 ’, which is also hook-shaped at its upper free end.

As can also be seen from FIGS. 1 and 2a, the frame 13 of each silo container 10 has rectangular, parallel cross-sections and upwardly projecting receptacles 130 for receiving loading tines of a forklift or pallet tongs. As already mentioned, the shaft connected to the closure cover 132 is mounted on the top of the receptacles 130.

Furthermore, an extension 150 is provided on the funnel 15, for example for attaching a vibrator. Furthermore, as can be seen from FIGS. 2a and 2b, circular or elongated sight glasses 6 or 6 'can be provided either in the side plate 111 or in the funnel 15. In FIG. 2a, a filling opening 113 is formed above the sight glass 6 ', to which, as can be seen from FIG. 3a, a slide 114 can be attached for refilling small quantities of pourable or flowable filling material. Since this filling material is generally accommodated in sacks, a row of teeth 115 is formed in the lower region of the chute, through which the sack material is slit open. 3b shows the chute 114, which is semicircular in cross section, in a plan view seen in the direction of arrow 8.

In addition to the upper frame 20, the underframe 2 also has a lower frame 21, which are connected to one another in a rigid and rigid manner by lateral struts 23 or transverse struts 22. As can be seen from FIG. 8, lateral stiffeners 24 are also provided in the base frame, and in the middle of the upper frame there is an extension 25, which corresponds in its position to the outlet opening 131 of the silo container 10. In the approach 25 can, as indicated schematically in Fig.8. 4th

AT 40t 916 B, for example, a mixer 9 can be attached. To clarify the illustration in FIG. 1, the attachment 25 and, for example, the mixer 9 are omitted.

In FIG. 8, a single-axle trailer is also shown schematically, on which the base frame 2 is pulled over a folded-down slope 82 by means of a winch 81, also shown schematically. With the aid of a single-axle trailer equipped in this way, a base frame forming the lower part of a silo unit can thus be easily brought to a construction site, for example by a car.

A modification of a silo container 10 'is shown in FIGS. 7a and 7b compared to FIGS. 2a and 2b. In contrast to the silo container 10 shown in FIGS. 2a and 2b, the silo container 10 'in FIGS. 7a and 7b has a schematically indicated screw conveyor 93 in the lower region of the hopper 15 in a side view (FIG. 7a) and in a top view (FIG. 7b) by means of which, for example, poorly flowing material is conveyed in the direction of the outlet opening 131.

In order to be able to stack empty silo containers 10 in a space-saving manner, two mutually opposite beams 16 are tiltably held between the projections of the support supports 11, as can be seen from FIGS. 6a and 6b. The position of the support bar 16 required for stacking is shown in FIG. In this position of the support beam, a closing mechanism 162 is simultaneously brought into such a position via a schematically indicated connecting link 161 that a lid 122 connected to the closing mechanism 162 is provided for closing the extension 121 assigned to the filling opening 120.

In the position shown in FIG. 6 a, the support bar 16 and thus the locking mechanism 162 are also during the transport; the support bar 16 and the closing mechanism 162 also assume the same position in the uppermost silo container of a silo unit. The support beam 16 and thus the closing mechanism 162 must be brought into the position shown in FIG. 6b before another silo container is placed on the respective silo container 10. As soon as the support beam 16 is brought into the position shown in FIG. 6b, the lateral support supports of the silo container to be placed can be inserted into the protruding angle iron 112, which is not shown in FIG. 6b. At the same time, it is ensured that, in this position of the beam 16, the closing mechanism 162 is released and thus the filling opening 120 of the lower-lying silo container is open.

The closed position of the closing mechanism 162 shown in FIG. 6 a is also schematically shown in FIG. 2 a and in the upper silo container IO 2 in FIG. 1. to recognize. A position of the support bar 16 corresponding to FIG. 6b is otherwise indicated by the reference number 161 for the lower silo container 10i in FIG.

A collapsible silo container 10 'is shown in FIGS. 9a and 9b and here the silo container 10' is shown in the assembled state in FIG. 9a, while it is shown collapsed in FIG. 9b. In the silo container 10 ', four support brackets 11' and 11 " are each at the four corners of an upper and lower, each approximately square support frame 110 'or 110 ". pivotally supported, the free ends of the mutually associated support supports 11 'and 11 " are, as can be seen from Fig.9a and 9b, so articulated so that they can either be brought into the open position shown in Fig.9a, in which they are secured by means of screw connections 18 ', for example, or they can be in the collapsed state shown in FIG. 9b, in which the support supports 11 'and 11 " are arranged approximately horizontally parallel to each other.

Between the two support frames 110 ’and 110 " a container made of a resistant, to some extent elastic plastic film 3 is provided and attached so that through it in the upper region of the silo container 10 ', which extends from the upper support frame 110' to approximately the lower end of the upper supports 11 ', an approximately cubic space is formed which merges in the lower region of the silo container 10 'into a funnel-shaped space tapering downwards in the form of a truncated pyramid, which ends at the attachment of the outlet opening 131.

The collapsible silo container 10 'shown schematically in FIGS. 9a and 9b creates a space-saving transportable and stackable silo container. Of the collapsible silo container 10 ', however, only two, but at most three, silo containers 10' should advantageously be placed one above the other. Apart from the articulated supports 11 'and 11 " and the plastic film 3 forming the container of the silo container 10 'corresponds with respect to the filling opening and outlet opening and with respect to the other securing and actuating elements of the silo container 10' to a silo container 10.5 described in detail with reference to FIGS. 1 to 8
