Description

The invention relates to a mobile agricultural distribution machine, preferably a field sprayer or a pneumatic fertilizer spreader. The invention also relates to a method for spreading at least two different distribution goods using a mobile agricultural distribution machine, preferably a field sprayer and/or a pneumatic fertilizer spreader.

Mobile agricultural distribution machines, preferably field sprayers and/or pneumatic fertilizer spreaders, are used for spreading and/or applying distribution goods such as fertilizers, seeds or crop protection products. Such distribution machines with a distribution linkage that is oriented transversely to the direction of travel and can be moved over a crop are known in different design variants.

The aim of the distribution machines mentioned is to spread a defined volume of distribution material, such as fertilizers and/or seeds and/or crop protection products, evenly and with a definable intensity on a plant population. In order to distribute the goods to be distributed over a large area on an agricultural area, the distribution booms of such distribution machines have laterally foldable booms with a large working width, sometimes more than twenty meters. Such wide distribution booms are folded and folded in for transport trips. When folded out, the arms are arranged transversely to the direction of travel. Dispensing elements, e.g. spray nozzles, are arranged at distances from one another on the distribution linkage for the metered application of the material to be distributed. The spreading elements create a spray fan directed towards the ground and/or the plants for the desired distribution of the material to be distributed.

However, the use of different distribution goods is often not enough. Pests such as the corn borer attack the corn inside the stem of the plant and can therefore often not be adequately controlled using conventional spreading materials. For this reason, an alternative control method involves spreading live biological products in the form of capsules on agricultural land. The capsules contain, for example, egg parasites of parasitic wasps, which are natural enemies of many pests in arable, vegetable and fruit cultivation.

The parasitic wasps (e.g. Trichogramma) that hatch from the capsules actively search corn plants for pests such as the corn borer and then lay their eggs in the corn borer eggs. This destroys the corn borer's eggs and produces more Trichogramma.

From the EP 3 150 492 B1 describes a dosing unit in the form of a ball discharge device, which is arranged on an aircraft and drops a distribution product in the form of capsules or balls for pest control. The dosing unit enables in particular precise delivery and at the same time targeted dosing of the distributed material

In the device known from the prior art, living biological products are distributed by means of a dosing unit. This means that only a distribution material in the form of capsules or balls is dispensed using a dosing unit. Two or more different distribution goods cannot be distributed at the same time using a mobile agricultural distribution machine. This means that different distribution goods such as fertilizers, seeds and/or plant protection products cannot be applied at the same time together with a living biological product, in particular during a crossing over an agricultural area.

The object of the invention is therefore to eliminate the described disadvantages of the prior art. In particular, a mobile agricultural distribution machine is to be provided, which enables at least two different distribution goods to be distributed simultaneously. In particular, it is the object of the invention to create a possibility for improved pest control by applying a living biological product, in particular by applying an environmentally friendly product.

These tasks are solved by a mobile agricultural distribution machine with the features of independent claim 1 and by a method for distributing at least two different distribution goods by means of a mobile agricultural distribution machine with the features of method claim 15. Advantageous embodiments and developments of the invention are in the claims and disclosed in the following description with partial reference to the figures.

According to a first aspect of the invention, a mobile agricultural distribution machine, preferably a field sprayer and/or a pneumatic fertilizer spreader, is provided. The agricultural distribution machine can be designed as a self-propelled distribution machine or as a distribution machine coupled to an agricultural towing vehicle (e.g. tractor).

The distribution machine comprises a distribution linkage, with a middle part and with two side arms, each of which is rotatably connected to the middle part via a pivot axis. The distribution linkage can have a high working width, ie a working width that is significantly larger than a width of the distribution machine, e.g. B. is a multiple of the width of the distribution machine. The working width of the distribution boom, ie the width in the working position and in the fully unfolded state, can be at least 18 meters, for example. The distribution linkage can be suspended in a swinging or rotating manner via at least one axis running in the direction of travel. For transport journeys, for example on a road, the distribution linkage can be folded using the pivot axes.

A plurality of dispensing elements is arranged on the distribution linkage, in particular on the two booms and on the middle part, the dispensing elements being set up for distributing at least a first distribution material such as fertilizer, seeds and/or crop protection products. The dispensing elements are preferably arranged at different positions along the distribution linkage. Particularly preferably, a line system of the distribution machine comprises at least two separate supply lines, wherein the dispensing elements for supplying at least the first material to be distributed can be connected in a fluid-conducting manner to a respective supply line. It is also possible for the dispensing elements to be able to dispense various first distribution goods at the same time. The dispensing elements preferably include spray nozzles, it being possible, for example, for different spray nozzles to be used at the same time. Depending on the type of first product to be distributed (e.g. crop protection products), a wide variety of application elements can be used, which application elements have different application properties. It is also possible to change an application quantity of the first material to be distributed using the application elements.

In order to achieve a simplified application of distribution goods with a higher effectiveness against pests, it is provided according to the invention that at least one dispensing element, connected to at least one dosing unit, is arranged on the distribution rod for dispensing at least a second distribution material, the metering unit being set up for dosing the second distribution material , which second distribution contains a living biological product.

As a result of the measures according to the invention, a mobile agricultural distribution machine is therefore provided for the simultaneous application of at least a first distribution product such as fertilizers, seeds and / or plant protection products and at least a second distribution product, which contains a living biological product, during a crossing on an agricultural area.

According to one embodiment, the distribution machine comprises a control device, wherein the control device is set up to control and/or regulate the dispensing elements and/or the at least one dosing unit and/or the at least one dispensing element. It is possible for the control device to control and/or regulate, for example, a quantity and/or number of first distribution goods and/or second distribution goods that are to be spread on the agricultural area.

According to a further aspect of the invention, the second distribution material is formed by a particularly capsule-like distribution material and the control device is set up to control and/or regulate the at least one dosing unit based on a predetermined number of capsules per unit area, preferably in such a way that in particular one capsule, preferably two or more capsules can be dispensed into storage positions using the dosing unit. The capsules can include, for example, spheres, grains or granules with a living biological product. A living biological product can, for example, include Trichogramma larvae (parasitic wasps), which preferably leave the capsule at different times after being released. It is possible that, for example, by releasing two or more capsules at a storage position, a higher level of pest infestation can be counteracted. It is also possible that the number of capsules, which are distributed at the storage positions by means of the at least one dosing unit, can be varied while the distribution machine is passing over an agricultural area, in particular in such a way that a current pest infestation and/or harmful growth is taken into account . The number of capsules per unit area can also be specified by a user, for example.

It is possible that an application quantity of the first distribution material can be controlled and/or regulated by the control device independently of an application quantity of the second distribution material. For example, the application rate of the first distribution material can be increased during a crossing on an agricultural area, while the application rate of the second distribution material remains constant. However, it is also conceivable that the application quantities of both distribution goods are increased or reduced at the same time or, for example, the application quantity of the first distribution material is increased and the application quantity of the second distribution material is reduced. This makes it possible to vary the application rates depending on requirements, for example if there is a high amount of harmful growth (e.g. weeds).

The dispensing elements are operatively coupled to supply the first material to be distributed, preferably with a line system, wherein the line system can be subjected to a variable delivery pressure by means of a conveyor device that can be controlled and/or regulated by the control device. It is possible for the first distribution material to be distributed using a ring pipeline system. The line system can preferably comprise at least one supply line and be connected to the dispensing elements. It is also possible for the line system to be designed as at least one pneumatic line system and to be connected to the dispensing elements.

It is possible that at least one monitoring means (e.g. camera, sensor, etc.) is preferably arranged downstream of the distribution linkage and/or the dispensing elements and/or the at least one dispensing element. The monitoring means can, for example, detect a distribution pattern of a distributed material and, for example, drops of liquid on plants. Any actual wetting of the plants detected by the monitoring means can be transmitted to the control device and application parameters (e.g. application rate, etc.) can be adjusted. An evaluation can thus be carried out by the control device, for example in which areas of an agricultural area - the plants were wetted, how strongly, i.e. how uniformly, the plants were wetted and / or with which drop spectrum, i.e. what drop size, the plants were wetted. It is also possible that, for example, a monitoring means is assigned to a group of dispensing elements and/or dispensing elements.

The goods to be distributed, in particular at least the first goods to be distributed and the second goods to be distributed, are preferably provided by at least one storage container of the distribution machine and, for example, conveyed with a feed pump via the line system to the respective dispensing elements and/or to the respective dispensing elements. It is possible that the feed pump includes, for example, a centrifugal pump.

According to a further embodiment variant of the invention, it is provided that an application of the first distribution material comprises a substantially flat distribution pattern, along a direction of travel and transverse to the direction of travel, and that an application of the second distribution material comprises an essentially punctiform distribution pattern, along the direction of travel and transverse to the direction of travel includes. This makes it possible for the first distribution material in the form of, for example, a plant protection product to be applied to an entire agricultural area and the second distribution material, which contains a living biological product, to be applied within certain storage positions. In particular, it is possible to adapt the flat distribution pattern and/or the punctual distribution pattern to an edge region of the agricultural area, in particular in such a way that, for example, no distribution material is spread in the area of a headland. The spreading of the distributed goods can, for example, be controlled and/or regulated variably, depending on the position and/or direction of travel, for example in the edge area of an agricultural area.

The punctual distribution pattern includes a plurality of storage positions arranged at a regular interval, which storage positions are spaced apart along the direction of travel by a first distance and are spaced transversely to the direction of travel by a second distance, the first distance and the second distance being substantially the same. It is possible for the storage positions to be arranged in a kind of checkerboard pattern on the agricultural area, which means that the first distance and the second distance are each 15m, for example. It is also conceivable that the storage positions on a conveyor belt of the distribution machine are at a certain distance from one another (e.g. every 10 meters). The distribution pattern and/or the interval can be adapted in particular to the shape and/or an edge area of the agricultural area. For example, the current position can be determined by a location determination module of the distribution machine and, for example, the storage positions can be planned using a planning module.

The punctual distribution pattern includes a plurality of storage positions arranged at a regular interval, which storage positions are spaced apart along the direction of travel by a first distance and are spaced transversely to the direction of travel by a second distance, the first distance and the second distance being different. This makes it possible, for example, for a storage position to be located along the direction of travel at a first distance of 10 meters and across the direction of travel at a second distance of, for example, 8 meters. The distances transverse to the direction of travel can, for example, be adapted to a working width of the distribution linkage and, for example, can also be divisible by a working width.

It is possible that the crop plants are arranged, for example, along essentially parallel rows and that the first distribution material and/or the second distribution material can be spread along the rows in the area of the rows, that is, for example, on the crop plants. It is also possible in the space between the rows, that is, for example, between a first and a second Row to distribute distribution material. This means, for example, that distribution material can be spread in the middle between the individual rows, along the rows. It is possible, for example, for distribution material to be distributed along every row or, for example, along every second row. The material to be distributed can, for example, be applied along the direction of travel on the crops and/or between the crops, but can be applied offset from one another transversely to the direction of travel, so that, for example, a kind of checkerboard pattern is created.

In order to ensure the desired distribution patterns in the area of delivery, the dispensing elements and the at least one dispensing element of the at least one dosing unit are coordinated with one another in their position in such a way that the first distribution material and the second distribution material can be dispensed without mutual influence and/or contact with the flat distribution pattern and the punctual distribution pattern takes place. It may be possible to influence and/or touch the distribution patterns in the impact area. Preferably, one or more monitoring means can be set up to detect the actual distribution pattern of the first distribution product and/or the second distribution pattern. The recorded actual distribution patterns can be transmitted to the control device and, if necessary, an adjustment of one or both distribution patterns can be initiated by the control device.

The distribution machine is set up to simultaneously distribute at least the first distribution material and the second distribution material during a crossing over an agricultural area. This makes it possible to spread at least two different distribution goods at the same time with just one pass over an agricultural area. It is also possible that during the journey, one of the distribution goods is only applied as needed, for example, the first distribution material in the form of, for example, plant protection products can only be applied to places where harmful growth (e.g. weeds) is detected by a monitoring means such as a Camera was detected. It is also conceivable that, for example, the second distribution material is specifically not applied in the area of the harmful growth, and thus a regular interval of application and/or a storage position is interrupted or shifted, for example.

It is possible for the at least one dosing unit to comprise a pneumatic conveying system for transporting distributed goods. The pneumatic conveying system can preferably transport distributed goods from a storage container to the at least one dosing unit. It can be provided that, for example, there are several supply lines for transporting distribution goods, for example that there is a supply line for each distribution goods.

The at least one metering unit can in particular be designed as a disc metering device with a separating disc and/or as a drum metering unit with a separating drum. It is possible that the at least one metering unit is preferably arranged on the distribution linkage and/or on a frame structure of the distribution machine. The at least one dosing unit can be set up in particular for the individual delivery of the second distributed product, i.e. for the individual dosage of capsules.

According to one embodiment, it is possible for a plurality of dosing units to be arranged at a short distance from one another and to form a central dosing unit. This makes it possible, for example, for the central metering unit to be arranged preferably in the middle of the distribution boom and for the dispensing elements to be distributed in the form of supply lines over the entire working width of the distribution boom. Alternatively or additionally, it is possible for a plurality of metering units to be arranged transversely to one another at a certain distance on the distribution linkage and for the metering units to be preferably operated and/or operable individually.

The at least one dispensing element of the at least one dosing unit can in particular comprise an opening on the at least one dosing unit. When the at least one dosing unit is arranged on the distribution rod, the material to be distributed can be dispensed using the opening. It is also possible for the at least one dispensing element of the at least one dosing unit to comprise one or more supply lines, which lead supply lines, for example, from a central dosing unit, preferably attached to a frame structure of the distribution machine, to the distribution linkage for dispensing distribution material. It is also possible for several dosing units to be attached to the frame structure of the distribution machine.

It is also possible for a number of dispensing elements to be at least twice, preferably three or many times greater than a number of dispensing elements. Due to the higher number of dispensing elements, a flat distribution pattern of the first distribution material can be made possible. The smaller number of dispensing elements preferably enables the punctual distribution pattern of the second distribution material.

An arrangement of the at least one dispensing element of the at least one metering unit on the distribution linkage is preferably dependent on driving alleys on an agricultural area and/or depending on an integer quotient resulting from a total working width of the distribution linkage and a number of dosing units and/or a number of the dispensing elements of the dosing units. If the entire working width of the distribution boom is, for example, 36 meters, the central metering unit can preferably be arranged on the distribution boom with four dispensing elements oriented transversely to the direction of travel in the form of supply lines. It is also possible for four metering units oriented transversely to the direction of travel to be arranged on the distribution linkage.

The distribution machines can include a location determination module (e.g. satellite-based system such as GPS system) for detecting a location of the distribution machine and deploying the first distribution material and/or the second distribution material based on the recorded location. This makes it possible, for example, to distribute the second distribution material at certain positions or locations on the distribution machine. For example, a specific interval can be specified (e.g. every 10 meters) at which the distribution material is distributed.

It is also conceivable that the first distribution material and/or the second distribution material is distributed based on a driving speed and/or a distance traveled by the distribution machine. By means of a current travel speed of the distribution machine, distribution material can be distributed preferably within a certain time interval (e.g. every 10 seconds) based on the resulting distance per time. The time interval can be defined, for example, by the control device and/or manually by an operator using, for example, an operating device. Distribution material can also be distributed based on a distance (e.g. every 10 meters).

It is possible for an application quantity of material to be distributed, in particular a number of capsules per unit area, to be applied based on a number of plants to be grown and/or grown per unit area. For example, if there is a high number of plants grown per unit area, the amount of material distributed per unit area can also be increased.

The control device has, for example, a computer unit, an on-board computer and/or the like and also includes a control and/or regulation circuit, in particular a hydraulic and/or pneumatic and/or electrical control and/or regulation circuit, wherein the control and/or regulation circuit / or control circuit is expediently designed for hydraulic and / or pneumatic and / or electrical signal and / or command transmission. Which signal and/or command transmission can also take place wirelessly (e.g. via WLAN).

In the context of the invention, the term control device includes, in particular, the entirety of the components for signal and/or command transmission. Accordingly, computer units, CPUs and/or the like are also included. Control devices integrated into the respective sensors or sensor units or sensor arrangements are also correspondingly included. It should also be noted that the signals and/or data from the sensors/measuring devices/detection devices and/or the like can each be used as feedback for a control and/or regulating variable.

It should also be noted that the terms “controls” and “regulations” and “control device” can refer to electronic and/or pneumatic and/or hydraulic controls or regulations that, depending on the training, can take on control tasks and/or regulation tasks. Even if the term “taxes” is used here, it can also usefully include “rules”. Likewise, when the term “rules” is used, “control” can also be included.

To avoid repetition, it should be noted that the embodiments and features according to the invention can be combined in any way and freely with the agricultural distribution machine and/or the method. Accordingly, all embodiments and features according to the invention are disclosed and claimable for both the agricultural distribution machine and the method.

The invention also includes a method for distributing at least two different distribution goods, preferably carried out by means of a mobile agricultural distribution machine, which distribution machine comprises a distribution linkage with a middle part and two side arms, each of which is rotatably connected to the middle part via a pivot axis.

The method also includes an application of at least a first distribution material, such as fertilizer, seeds and/or plant protection products, by means of a plurality of application elements which are arranged on the distribution linkage, in particular on the booms and on the middle part.

The method also includes dosing at least a second material to be distributed, which contains a living biological product, with at least one dosing unit and dispensing at least least of the second distribution material with at least one dispensing element arranged on the distribution rod.

In a preferred embodiment of the method according to the invention, this can be carried out with a mobile agricultural distribution machine according to one of the embodiments described above, in particular with a field sprayer or a pneumatic fertilizer spreader according to one of the embodiments described above.

According to one embodiment, the number of capsules to be distributed per unit area can be adjusted, preferably taking into account a number of crops grown per unit area and/or preferably a number of harmful growth and/or pests per unit area. A monitoring means 50 (see 2a and 2 B) can be set up to record crops, harmful vegetation and/or pests per unit area and be connected to the control device.

An application quantity of the first distribution material can be controlled and/or regulated by the control device independently of an application quantity of the second distribution material. According to a further exemplary embodiment, it is also possible for the application quantities of the distribution goods to be dependent on one another, e.g. it is possible for the application quantity of the second distribution material to be automatically increased when the application quantity of the first distribution material is increased.

2a and 2 B each show a highly schematic view of dispensing elements 14 and dispensing elements 15 of a distribution linkage 10 of the mobile agricultural distribution machine 200.

The distribution machine 200 can comprise a plurality of metering units 20 arranged at a short distance from one another, which form a central metering unit 20 and/or a plurality of transversely spaced metering units 20 arranged on the distribution linkage 10, in particular individually operated and/or operable, are present. 2a shows a total of four dosing units 20, each with a dispensing element 15, which are arranged at a certain distance on the distribution linkage and are preferably operated and/or operable individually. Two or more dispensing elements 15 can also preferably be attached to a dosing unit. 2 B shows four dosing units 20 arranged at a short distance from one another, which form a central dosing unit 20. The central dosing unit 20 is preferably attached to a frame structure of the distribution machine 200, the dispensing elements 15 of the central dosing device 20 preferably comprising supply lines which preferably lead the distribution material to the distribution rod 10.

A majority of the dispensing elements 14 are arranged on the distribution linkage 10, in particular on the booms 12 and on the middle part 11. The spreading elements 14 are set up to spread at least the first distribution material such as fertilizers, seeds and/or crop protection products.

The at least one dosing unit 20 includes a pneumatic conveying system for transporting distributed goods. According to the exemplary embodiment, the pneumatic conveying system can distribute goods from the storage container 40 (see 1 ) via preferably several supply lines to the four dosing units 20.

An arrangement of the at least one dispensing element 15 of the at least one metering unit 20 on the distribution linkage 10 is preferably dependent on a tramway on an agricultural area 300 and/or dependent on a total working width B of the distribution linkage 10 and a number of the metering units 20 and/or a number of delivery elements 15, resulting integer quotient. According to the exemplary embodiment, four metering units 20 are arranged on the distribution linkage 10, so that the distribution linkage 10 can have a working width B of, for example, 36m.

According to one exemplary embodiment, the distribution linkage 10 has a monitoring means 50 in the form of preferably several sensors. A height H defines a distance of the distribution linkage 10 from a ground surface and can preferably be detected by means of the monitoring means 50.

The position of the dispensing elements 14 and the at least one dispensing element 15 of the at least one dosing unit 20 are coordinated with one another in such a way that the first dispensing material and the second distributing material are dispensed without mutual influence and/or contact between the flat and punctual distribution patterns. According to the exemplary embodiment, the dispensing elements 14, for example, dispense a spray liquid in the form of a plant protection agent, with each dispensing element 14 generating a spray fan. In the area of a delivery, the spray fan should not be influenced by the application of the second distribution material. In an impact area (e.g. on a floor surface), contact between the first distributed product and the second distributed product can take place.

The dispensing elements 14 are operatively coupled to a line system for supplying the first material to be distributed, wherein the line system can be subjected to a variable delivery pressure by means of a conveying device that can be controlled and/or regulated by the control device. According to the exemplary embodiment, the line system is designed to transport liquid and preferably comprises a plurality of supply lines which are connected to the dispensing elements 14 and are set up to dispense the first material to be distributed.

A number of dispensing elements 14 is at least twice, preferably three times or many times larger than a number of dispensing elements 15. According to the exemplary embodiment, four dosing units 20, each with a dispensing element 15, are arranged on the distribution linkage 10 (see 1 ), whereas the number of dispensing elements 14 is eight times higher than the number of dispensing elements 15.

3a and 3b show a highly schematic top view of an agricultural area 300, on which the mobile agricultural distribution machine 200 is preferably movable along a direction of travel FR, along tramlines.

The dispensing of the first distribution material includes a substantially flat distribution pattern, along a direction of travel FR and transversely to the direction of travel FR. The dispensing of the second distribution material, on the other hand, includes a substantially punctual distribution pattern along the direction of travel FR and transversely to the direction of travel FR. The distribution patterns are preferably adapted to an edge area (e.g. headland) of the agricultural area 300. According to the 3a and 3b No distribution material is spread in the headland area. In order, for example, to pause and/or stop the application of distribution material, for example in the edge area, the control device is set up to control and/or regulate the application elements 14 and/or the dosing units 20 and/or the delivery elements 15.

3a and 3b show two embodiments of the punctual distribution pattern, which have a plurality of storage positions 30a-30d arranged at a regular interval; 32a-32c include storage positions 30a-30d; 32a-32c are spaced along the direction of travel FR by a first distance D1 and are spaced transversely to the direction of travel FR by a second distance D1. According to the in 3a In the exemplary embodiment shown, the first distance D1 and the second distance D2 are different. 3b shows storage positions 32a-32c, where the distance D1 and the distance D2 are essentially the same.

The storage positions 30a-30d 3a are arranged in a kind of checkerboard pattern, while the storage positions 32a-32c of 3b are arranged at equal distances. According to a further embodiment, not shown, it is also possible for the monitoring means 50 (see 2 ) For example, harmful growth in the form of weeds or the like is detected and the punctual distribution pattern is adjusted (e.g. suspended or moved) based on the detected harmful growth. The flat distribution pattern can preferably be applied over the entire agricultural area 300 or alternatively, for example, only in the area of the identified harmful growth. It is also possible for the flat distribution pattern to comprise a strip-shaped distribution pattern, for example along rows of crop plants.

Although the invention has been described with reference to specific embodiments, it will be apparent to those skilled in the art that various changes may be made and equivalents substituted without departing from the scope of the invention.
