The preferred exemplary embodiments of the invention described with reference to the figures correspond in part, with similar or identical parts being provided with the same reference symbols and for their explanation reference can also be made to the description of other exemplary embodiments. For purposes of illustration, not all parts are referenced in all figures.

the 1 until 9 12 show different views of a distribution device 100 or sections thereof according to an embodiment of the invention, together with reference to the 1 until 9 is described.

The distributor device 100 is intended for use with an agricultural distributor machine 200 (e.g. 14 ff) for spreading distribution material, such as e.g. B. seeds and / or fertilizers. The distributing machine 200 can be a seed drill, in particular for drill sowing and/or for precision sowing. It should be mentioned here that fertilizers and/or seeds can be used in particular as distribution material for drilling and/or precision sowing, so that z. B. during a distribution process z. B. fertilizer can be applied as part of drill seeding and seed can be applied as part of precision sowing.

The distributor device 100 comprises a line section 1 for preferably pneumatically feeding the material to be distributed to a distribution section 2 for distributing the material to be distributed, in particular to what is known as a distributor head 2. The material to be distributed can be guided into the distribution section 2 in particular via a material to be distributed outlet 5 of the line section 1. The distribution section 2 serves in particular to distribute the distribution material to a large number of row units 201 (e.g. 14 ff) for outputting the material to be distributed onto a field, in particular into a furrow in the field.

The distribution section 2 comprises a large number of first distribution material outlets 3 (eight in the exemplary embodiment shown) and a large number of second distribution material outlets 4 (sixteen in the exemplary embodiment shown) and a cover 10 that can be attached and removed and/or to block at least one second distribution material outlet 4 directly or indirectly.

The first distribution material outlets 3 are arranged in a ring shape in a first ring, evenly spaced from one another, and the second distribution material outlets 4 are arranged in a ring shape in a second ring, spaced evenly from one another, with the first ring and the second ring being arranged coaxially with one another and having different diameters, which is particularly important good in the 8th and 9 you can see. The first ring and the second ring are also designed coaxially to the distribution material outlet 5 of the line section 1 . The first distribution material outlets 3 and/or the first distribution material lines 30 (only shown schematically) connected thereto preferably have a larger passage cross section than the second distribution material outlets 4 and/or the second distribution material lines 40 (only shown schematically) connected thereto. However, exemplary embodiments are also possible in which the first distribution material outlets 3 and/or the first distribution material lines 30 connected thereto have a passage cross section of the same size as the second distribution material outlets 4 and/or the second distribution material lines 40 connected thereto.

The first distribution material lines 30 and the second distribution material lines 40 serve to transport the distribution material from the distribution section 2 to the row units 201 .

In an exemplary embodiment that is not shown, it is possible for the first distribution material outlets 3 and the second distribution material outlets 4 to be arranged in a common ring. The first distribution material outlets 3 and/or the first distribution material lines 30 connected thereto can expediently have a larger or the same passage cross section as the second distribution material outlets 4 and/or the second distribution material lines 40 connected thereto. The number of the first distribution material slopes 3 and the second distribution material outlets 4 can also be the same be large or different.

The distribution section 2 has, in particular, a distribution goods space 6 which is delimited by a base plate 7 at the front at the bottom and is delimited radially laterally on the outside by an annular delimiting structure 8 . The first distribution material outlets 3, the second distribution material outlets 4 and the distribution material outlet 5 of the line section 1 open via the base plate 7 in the distribution material space 6. The distribution section 2 and in particular the distribution space 6 are delimited at the top by the cover 10 and in particular by its main plate 11.

The cover 10 is designed to block at least one first outlet 3 for distribution and/or at least one second outlet 4 for distribution. The cover 10 is thus used to control, in particular blocking and/or releasing, the distribution of the material to be distributed from the distribution section 2 and in particular from the distribution space 6.

The cover 10 comprises a main plate 11 and is designed as a reversible cover. The lid 10 includes a first panel side having a first locking and/or unlocking configuration, preferably for a first mode of operation, and a second panel side having a second locking and/or unlocking configuration, preferably for a second mode of operation. The first plate side and the second plate side face in opposite directions relative to the main plate 11, e.g. B. up and down.

the 1 until 7 primarily serve to explain an exemplary embodiment in which the first side of the plate, which points downwards and interacts with the distribution section 2, is active and the second plate side facing up is inactive.

the 10 until 13 serve primarily to explain an embodiment in which the downward-pointing and cooperating with the distribution section 2 second plate side is active and the upward-pointing first plate side is inactive.

Referring again to the 1 until 7 the first plate side of the cover 10 is inserted into the distribution section 2 and in particular into the distribution space 6 in order to be able to control the distribution of the material to be distributed.

The first side of the plate includes a first locking and/or releasing configuration that is particularly useful in the 10 , 11 and 12 you can see.

The first locking and/or releasing configuration has an annular locking plate 12 with a central distribution material through-opening 13 and z. B. a variety of optional distribution material guide elements 14 which preferably extend radially outwards.

The blocking plate 12 serves to block all the first distribution material outlets 3 in an appropriate manner. The central distribution material passage opening 13 and the optional distribution material guide elements 14 serve to distribute the distribution material to all second distribution material outlets 4.

The cover 10, in particular the main plate 11, serves to delimit the distribution section 2 and in particular the distribution space 6 at the front at the top, while the base plate 7 with the distribution goods outlet 5, the first distribution goods outlets 3 and the second distribution goods outlets 4 defines the distribution section 2 and in particular the distribution space 6 limited at the front below. The distribution section 2 and in particular the distribution space 6 are delimited by the ring-shaped delimiting structure 8 laterally on the outside in the circumferential direction.

the 10 until 13 show different views of the distributor device 100 or sections thereof. In the 10 until 13 is the lid 10 compared to the 1 until 7 but rotated 180°.

In the 11 until 13 the second plate side pointing downwards and cooperating with the distribution section 2 is active and the first plate side pointing upwards is inactive.

In the 11 until 13 the second plate side of the cover 10 is inserted into the distribution section 2 and in particular the distribution space 6 in order to be able to control the distribution of the distribution material.

The second side of the plate includes a second locking and/or releasing configuration, e.g. B. particularly good in the 1 until 5 you can see.

The second locking and/or releasing configuration has an annular locking flange 15 with a preferably central passage 16 for the material to be distributed. The locking flange 15 preferably protrudes from the main plate 11 .

The blocking flange 15 is designed to preferably block all second distribution material outlets 4 . The distribution material passage 16 serves to guide the distribution material to all of the first distribution material outlets 3.

A comparison in particular 1 until 7 on the one hand and the 10 until 13 on the other hand shows that the cover 10 is designed as a reversible cover, with a first plate side for a first operating mode and a second plate side for a second operating mode. However, instead of a cover 10 with two plate sides for two different operating modes, it is also possible to provide two or more than two covers 10 for only a single operating mode.

The in the 1 until 13 The blocking and/or release configurations shown represent advantageous exemplary embodiments. However, it is obvious to the person skilled in the art that a large number of other blocking and/or release configurations are possible for other operating modes. So the lid 10 z. B. be designed to block only a single first Verteilgutabgang 3 to block several first Verteilgutabgänge 3, or to block all first Verteilgutabgänge 3. Alternatively or additionally, the cover 10 can be designed to block only a single second distribution material outlet 4, to block several second distribution material outlets 4, or to block all second distribution material outlets 4.

The cover 10 can thus z. B. be designed for individual series shutdown or section series shutdown.

14 shows a perspective view of a distribution machine 200 according to an embodiment of the invention, wherein 15 12 shows an enlarged portion of the dispensing machine 200. FIG.

The distributing machine 200, which is expediently designed as a sowing machine, comprises two reservoirs 202, 203 for receiving a different material to be distributed and two distributing devices 100. The two distributing devices 100 can, but do not necessarily have to, be of identical design. It is possible that in particular the distribution sections 2 and/or the covers 10 of the distribution devices 100 are designed differently.

The distribution machine 200 comprises a large number of row units 201 (thirty-one in the exemplary embodiment shown) that can be supplied with distribution material via the distribution devices 100 for discharging the distribution material on a field.

The distribution machine 200 further includes two in the 14 and 15 not to be seen dosing for volumetric dosing each different Verteilguts and at least one in the 14 and 15 conveying air generating device (e.g. one or more blowers) for generating an air volume flow, which can also not be seen, by means of which metered distribution material can be transported to the distribution devices 100 .

The dosed material to be distributed can be expediently divided in the distribution sections 2 and transported pneumatically to the associated row units 201 by means of air volume flows which are likewise expediently divided. For this purpose, the individual row units 201 are expediently connected to one or more distribution devices 100 via the first distribution lines 30 and/or the second distribution lines 40, with the first distribution lines 30 and/or the second distribution lines 40 being in the 14 and 15 have been omitted for illustration purposes.

The dosing devices can be conventional dosing devices for volumetric dosing, in particular, such as cell rotors or dosing rollers, which, for. B. can be part of a rotary valve.

The row units 201 are evenly spaced along a support structure 204 . The row units 201 are e.g. B. via a respective pivot structure (e.g. a parallelogram pivot structure) with the support structure 204 expediently pivotably connected and alternately protrude at different distances from the support structure 204, in particular to the rear.

The distribution machine 200 is used to output preferably different goods to be distributed, e.g. B. different seed types or seeds on the one hand and fertilizer on the other.

A distributor device 100 can, for. B. be assigned to an even number of row units 201 on one half of the support structure 204, z. B. sixteen row units 201 as in the embodiment of FIG 14 .

The other distribution device 100 can, for. B. be assigned to an odd number of row units 201 on the other half of the support structure 204, z. B. fifteen row units 201 as in the embodiment of FIG 14 . A distribution material outlet for the non-existent sixteenth row unit, which in particular represents an outermost row unit relative to the longitudinal direction of the support structure 204, can be blocked by the cover 10 of the associated distribution device 100.

16 shows a schematic representation of a pattern of distribution goods with two different distribution goods.

It is Z. For example, it is possible for the distribution machine 200 to have two reservoirs for different distribution items, namely a first reservoir for a first distribution item and a second reservoir for a second distribution item. For this purpose, the distribution machine 200 can e.g. B. preferably comprise two metering elements that can be operated independently of one another, namely a first metering element for the first material to be distributed and a second metering element for the second material to be distributed.

The different products to be distributed are shown schematically by dashed lines for a first product to be distributed and dotted lines for a second product to be distributed. They form an especially uniform pattern of dispensing goods with an alternating sequence between the first goods to be distributed and the second goods to be distributed.

The cover 10 can, for. B. can be used to deactivate one or more row units 201 in a targeted manner, so that a single row or section shutdown is made possible via the cover.

17 shows a schematic representation of a pattern of distribution goods with three different distribution goods.

It is Z. For example, it is possible for the distribution machine 200 to have three storage containers for different goods to be distributed, namely a first storage container for a first product to be distributed, a second storage container for a second product to be distributed, and a third storage container for a third product to be distributed. For this purpose, the distribution machine 200 can e.g. B. preferably comprise three metering devices that can be operated independently of one another, namely a first metering device for the first material to be distributed, a second metering device for the second material to be distributed and a third dosing element for the third material to be distributed.

The different products to be distributed are shown schematically by dashed lines for the first product to be distributed, solid lines for the second product to be distributed and dotted lines for the third product to be distributed. They form an especially uniform material distribution pattern with an alternating sequence between first material to be distributed and second material to be distributed and third material and second material distributed jointly.

The cover 10 can, for. B. can be used to deactivate one or more row units 201 for at least one item to be distributed or in total.

It is preferred that the distribution machine 200 can include a separate distribution device 100 for each different material to be distributed.

The invention is not limited to the preferred embodiments described above. Rather, a large number of variants and modifications are possible, which also fall within the scope of the claims.
