Description

[0001] Spreader for spreading grit

[0002] The invention relates to a spreader for spreading grit according to the preamble of patent claim 1 and a winter service spreader or agricultural spreader according to the preamble of patent claim 8.

[0003] In the field of municipal technology and / or agriculture, a variety of trailed, mounted and / or self-propelled spreading machines are known for spreading grit. Depending on the type of application, such grit can be granular, grainy or powdery material. In agriculture, such grit is often spread in the form of fertilizer or lime on cultivated areas such as fields or pastures, for example, to influence soil values ​​and / or plant growth. In municipal technology, particularly in winter maintenance, such grit is usually spread in the manner of sand, grit, salt and / or brine on public roads, parking lots or the like in order to influence their surface adhesion.

[0004] Such spreading material is often applied in a combination of a purely granular, granular or powdery material and at least one liquid material, depending on the application, e.g. water, liquid fertilizer, brine, etc.

[0005] Spreading material is typically achieved using spreaders that allow for an even and widespread distribution of the material. These types of spreaders have at least one spreading element, often designed like a rotating spreading disc. The material to be spread is directed onto the rotating spreading element, which spreads it evenly using centrifugal forces. A rearward-facing spreading fan is formed on each spreading element, through which the material is applied to the field, road, or similar area, depending on the application.

[0006] In order to hold or store the spreading material to be spread, generic spreading devices have at least one storage container which is at least partially funnel-shaped and / or arranged above the spreading device.

[0007] Spreaders with storage containers have become known from publications such as DE 40 08 630 A1, DE 41 25 965 A1 or WO 90 / 08227 A1, which have at least one additional liquid container for holding the respective liquid material. The liquid container is designed as a side wall of the storage container or is integrated into the side walls of the storage container. The problem with spreaders designed in this way is that the side walls of such storage containers build up laterally, given the already limited permissible vehicle width, and this severely restricts the capacity for the granular and / or liquid material. Compared to conventional storage containers, which are designed for only one granular or liquid material to be applied, storage containers of this type suitable for multiple materials are relatively complex.

[0008] The document DE 31 43 316 C1 discloses a spreader with a storage container in which the at least one liquid container is arranged entirely within the storage container in the manner of an additional container. The disadvantage of this is that the capacity of the storage container for the other material to be spread, particularly granular material, is reduced or restricted.

[0009] Furthermore, from the document DE 103 59 179 A1, storage containers for spreading devices have become known, to which at least one container attachment can be attached and / or arranged on an upper side, preferably at a filling opening, of the storage container. Such a container attachment is designed in particular to increase the capacity of the storage container, in particular as needed and / or in a retrofittable manner, for the material to be spread, in particular granular, or to provide an additional capacity for the spreading material. However, such storage containers are only designed for one material or spreading material to be spread, in particular granular. The storage or transport of at least one additional, in particular liquid, material or liquid is therefore not possible.

[0010] The object underlying the invention is therefore to design a spreader with at least one storage container in such a way that several, in particular different and / or additionally liquid, materials to be spread can be stored and / or transported in a particularly space-saving manner. In particular, the object of the invention is to at least partially eliminate the described disadvantages of the prior art.

[0011] This object is achieved according to the invention in that the container attachment is designed in the manner of an additional container for receiving at least one further material to be dispensed, preferably a liquid.

[0012] Accordingly, a container attachment is provided for the spreader, which is designed in particular in the manner of a tank. Preferably, the container attachment can be attached and / or arranged at least approximately on the top side or upper edge of the storage container. As a result of this measure, the spreader is designed to receive and / or store at least one further, in particular liquid, material without at least significantly influencing the, in particular original, width of the spreader and / or the storage container. Furthermore, this achieves the result that the top side or upper edge of the storage container is shifted further upwards in height by the container attachment, thus changing the overall height of the storage container. In a particularly advantageous embodiment, the capacity of the storage container is at least almost unchanged or even increased when the container attachment is used.

[0013] In this context, it is further proposed that the container attachment be made of a plastic material, preferably as an injection-molded part. Such a container attachment can be produced relatively inexpensively. In a preferred embodiment of the spreader according to the invention, the container attachment is at least substantially rotationally symmetrical, in particular in the manner of a rotating part. In other words, the container attachment, in particular the additional tank, is preferably annular and particularly preferably designed with at least one filling and / or through-opening for the spreading material to the storage container. The container attachment is preferably rotationally symmetrical with respect to a vertical axis of symmetry of the storage container. Furthermore, the container attachment is preferably oval or rectangular, at least in sections.Alternatively or additionally, the container attachment can be attached to the storage container in such a way that one vertical axis of symmetry of the container attachment corresponds to a vertical axis of symmetry of the storage container. Such an embodiment has the advantage that the container attachment is even easier to manufacture and mount on the storage container.

[0014] In a further development of the spreader according to the invention, the container attachment has an upper section that can be placed and / or is placed on the storage container, in particular the upper side, in the manner of a collar. The container attachment preferably has a plurality of sections, wherein at one of its ends, preferably on the upper side, a rim or collar that protrudes and / or runs around the entire width is formed. Particularly preferably, the rim or collar is formed externally at least approximately flush with the storage container, so that the outer width of the container attachment, in particular of the rim or collar, corresponds to the outer width of the storage container. Furthermore, the container attachment can preferably be attached to the storage container in such a way that the underside of the upper section, in particular of the rim or collar, rests on the upper side, in particular the rim, of the storage container.This ensures particularly good accessibility of the container attachment.

[0015] Alternatively or additionally, one or more fixing points can be formed on the upper section, in particular on the outside of the rim or collar, by means of which the container attachment can be reversibly connected to the storage container and thus fastened. Furthermore, the container attachment preferably has at least one closable container opening arranged on the rim or collar, by means of which the at least one further material, in particular the liquid, can be poured into the container attachment and which is particularly preferably designed in the manner of a tank cap. Alternatively or additionally, the container attachment has a plurality of container openings, which are further preferably each provided for different materials, in particular liquids. With such an arrangement, the at least one container opening is particularly easily accessible for an operator.Furthermore, the container attachment can alternatively or additionally have different chambers for different materials to be dispensed, in particular liquids. Furthermore, the different chambers of the container attachment can alternatively or additionally be arranged horizontally next to one another or vertically one above the other.

[0016] In another preferred embodiment of the spreader according to the invention, the container attachment has a lower section which projects into the storage container from above and which can be attached and / or arranged to overlap the inner wall of the storage container at least partially, preferably by at least one third. The lower section is preferably offset inwards or towards the vertical axis of symmetry in terms of width. The container attachment is preferably designed and attachable to the storage container in such a way that, on the one hand, the lower section of the container attachment is arranged at least largely below the filling opening of the storage container, while, on the other hand, the upper section of the container attachment is arranged at least almost entirely above the filling opening of the storage container. With such an embodiment, a particularly large capacity is achieved within the container attachment.Particularly preferably, at least one outlet is formed on the lower section, by means of which the at least one material to be dispensed, in particular the liquid, can be discharged from the container attachment. Alternatively or additionally, several outlets, preferably intended for different materials or liquids, can also be formed on the lower section of the container attachment.

[0017] In another embodiment of the spreader according to the invention, the container attachment has a step-like offset, preferably arranged between the upper and lower sections, which points toward the interior of the storage container and / or tapers, by means of which the container attachment can be placed and / or is placed on the storage container. In such an embodiment, the container attachment is positioned particularly securely in the storage container.

[0018] In a further preferred embodiment of the spreader according to the invention, the container attachment, in particular the lower section, is designed to be at least partially pushed into the storage container. In other words, it is preferred according to the invention if the container attachment or the additional tank can be or is inserted at least partially, in particular from the inside, into the storage container. This allows for particularly simple assembly and / or disassembly of the container attachment. The container attachment is preferably designed such that at least the lower section can be attached and / or arranged at least partially adjacent to the inner wall of the storage container.

[0019] In a further development of the spreader according to the invention, the upper section, in particular an upper edge of the container attachment forming a filling area for the spreading material, is designed to slope downwards towards the interior of the storage container. The container attachment preferably has a descending or negative incline or gradient of at least 1% or more on its upper edge or upper rim, which particularly preferably points or slopes downwards from the outside to the axis of symmetry of the storage container and / or the container attachment. The descending or negative incline or gradient can also be between 2% - 20%, preferably between 5% - 10%. This has the advantage that materials located on the container attachment, in particular the upper edge, such as spreading material, liquids, contaminants or the like, such as accidentally spilled material, at least largely slip and / or slide into the storage container.The object underlying the invention is also achieved with a winter service spreader or an agricultural spreader, wherein the winter service spreader or the agricultural spreader is designed according to at least one of the preferred embodiments of the invention described above. Regarding the advantages and modifications of the winter service spreader or the agricultural spreader according to the invention, reference is first made to the advantages and modifications of the spreader according to the invention.

[0020] Further details of the invention can be found in the example description and the drawings. The drawings show

[0022] Fig.2 is a perspective view of a container attachment of the winter service spreader in a removed state;

[0023] Fig.3 the winter service spreader with built-in container attachment in perspective partial section; and

[0024] Fig.4 the winter service spreader in a side view from the left.

[0025] The illustration in Fig.1A shows a perspective view of a spreader 1 for spreading grit. In the embodiment shown, the

[0026] Spreader designed in the manner of a municipal winter service spreader 1 and intended for spreading salt or the like on public roads, parking lots, or other public areas. Alternatively, the spreader 1 can also be designed as an agricultural spreader, for example as a fertilizer spreader or centrifugal fertilizer spreader, and intended for spreading grit on agricultural land, for example a grain field or pasture. With an agricultural spreader 1, a wide variety of grit can be spread on the land, in particular powdered or granular fertilizer as well as lime or the like. The spreader 1 can be attached in a portable manner to a tractor (not shown in the figures), but can alternatively also be attached to a tractor or be self-propelled.Furthermore, the spreader 1 can also be designed in the manner of other distribution machines known in agriculture, for example, as a pneumatic fertilizer spreader or a seed drill. As a rule, the spreader 1 is moved along the direction of travel F shown.

[0027] For the surface distribution of the spreading material, the spreader 1 has a spreading element 10. The spreading element 10 is designed as a spreading disc which is driven in rotation for distribution. The spreading material is guided from above onto the rotating spreading element 10, in particular a respective drop point on the spreading element 10, via a feed line and / or dosing device (not shown) from a storage container 20 arranged above the spreading element 10. Due to the rotational speed or rpm of the spreading element 10, the spreading material is centrifugally distributed behind the spreader 1 against the direction of travel F using centrifugal forces. As an alternative to the embodiment shown, the spreader 1 can also have more than one spreading element 10. In particular, the spreader 1 can have two spreading elements 10, in particular spreading discs, which are driven in counter-rotation to one another.

[0028] Frequently, in addition to the spreading material, at least one further material is to be applied or distributed, preferably together with the spreading material. This can, for example, be at least one liquid, such as water, brine, liquid fertilizer, or the like, which can be added to the spreading material and / or mixed with it in an adjustable manner within the spreader. Alternatively or additionally, it can also be provided that the at least one further material, in particular the liquid, is applied together and / or alongside the spreading material onto the at least one spreading element 10.

[0029] The spreader 1 shown comprises a container attachment 30 according to the invention, which is arranged on an upper side, in particular at a filling opening 21, of the storage container 20. The container attachment 30 is particularly designed to provide additional capacity for the spreading material in the storage container 20. Alternatively, the container attachment 30 can at least partially reduce the capacity of the storage container 20. Furthermore, the container attachment 30 can alternatively also be designed such that the capacity of the storage container 20 remains unchanged when the container attachment 30 is inserted or mounted.

[0030] According to the invention, the container attachment 30 is designed as an additional container for accommodating the at least one additional material to be dispensed, in particular the at least one liquid such as water or brine. In other words, the container attachment 30 is designed as an additional liquid tank.

[0031] As can be seen particularly clearly in Fig. 2, the container attachment 30 is at least substantially rotationally symmetrical, in particular in the manner of a rotating part. The container attachment 30 is formed as a plastic part. Alternatively, the container attachment 30 can also be made of metal, for example, as a stainless steel tank. As can be seen in the figure, the container attachment 30 is rotationally symmetrical about a vertical axis of symmetry X, which, in the installed state, is arranged at least approximately corresponding to the axis of symmetry of the storage container 20.

[0032] The container attachment 30 has in the upper region an upper section 31 which can be placed and / or attached to the storage container 20 in the manner of an edge or collar 310.

[0033] As can also be seen, the container attachment 30 has a container opening 31 arranged on the edge or collar 310 and / or closable, by means of which the at least one further material, in particular the liquid, can be poured into the container attachment 30. Alternatively or additionally, the container attachment 30 can also have a plurality of container openings 311, in particular intended for different liquids. The container opening 311 shown in this exemplary embodiment is designed in the manner of a closable tank cap. Furthermore, a plurality of fixing points 312A, 312B are formed along the edge or collar 310, by means of which fixing points the container attachment 30 can be connected or fastened to the storage container.

[0034] As can be seen more clearly in Fig. 3, the container attachment 30 has a lower section 32 that projects into the storage container 20 from above and can be attached and / or arranged to at least partially overlap the inner wall of the storage container 20. The lower section 32 overlaps the upper part of the storage container 20 by at least a quarter or a third. Alternatively, it would also be conceivable for the lower section 32 to overlap more or less of the inner wall of the storage container 20.

[0035] The container attachment 30 has at least one outlet 320 on the lower portion 32, through which the at least one further material to be dispensed, in particular the liquid, can be discharged from the container attachment 30. Alternatively or additionally, a plurality of outlets 320 can also be formed on the lower portion of the container attachment 30.

[0036] Furthermore, an offset 33 pointing towards the interior of the storage container 20 and / or tapering in the manner of a step is formed on the container attachment 30.

[0037] The offset 33 is arranged between the upper and lower sections 31, 32 of the container attachment 30. By means of the offset 33 and / or collar 310, the container attachment 30 can be placed and / or mounted on the storage container 20.

[0038] To mount the container attachment 30, the container attachment 30, in particular the lower section 32, can be pushed into the storage container 20 or the filling opening 21 of the storage container 20.

[0039] As can also be seen in Fig.3, the upper section 31, in particular the upper edge 310 of the container attachment 30 forming the filling area 21 for the spreading material, is designed to slope downwards towards the interior of the storage container 20 and / or towards the axis of symmetry X. As a result, the material located on the edge or collar 310 or the upper edge of the container attachment 30

[0040] Material, such as grit or a liquid, flows into the storage container 20.

[0041] Fig. 4 shows the spreader 1 from the side. Viewed in the direction of travel F, an additional tank 40 can be seen arranged in front of the storage container. The additional tank 40 is designed to hold at least one additional material, in particular a liquid. Alternatively or additionally, the additional tank 40 can also be designed to hold the material stored in the container attachment 30, so that an even larger quantity of the additional material, in particular the liquid, can be carried.

[0042] Furthermore, the container attachment 30 can alternatively or additionally also have different chambers for different materials to be dispensed, in particular liquids. Furthermore, the different chambers of the container attachment can alternatively or additionally be arranged horizontally next to one another or vertically one above the other.

[0043] It is understood that the features mentioned in the previously described embodiments are not limited to these specific combinations and are also possible in any other combinations. Furthermore, it is understood that the geometries shown in the figures are merely exemplary and are also possible in any other configurations.
