Definitions
- the invention relates to a device for dosing or individual distribution of material particles, in particular seed and/or fertilizer, on agricultural land, with at least one storage container which has at least one chamber for storing a loose bed of material particles in its interior.
- Devices for separating seed are known in principle, for example from DE 1 582 116 A, which discloses a precision seed drill with a storage container that has a cell disk in its lower area, which forms a bottom part of the same and is mounted on a sleeve fastened in the container. Cells are evenly distributed on the cell disk and closed off at the bottom by a cover disk with a recess. Furthermore, seed guide tubes are firmly connected to the cell disc, on the arrangement corresponding to the cells, which rotate in an imaginary truncated cone and whose free end forms the grain exit point. When using a rigid cell disc, the possibilities for modification and adaptation of the device to customer requirements are limited.
- Also known from DE 81 20598.8 U1 is a device for separating and sowing seeds from a mass of seeds, with a seed container, the bottom of which is a rotatably mounted, drivable distributor disk which has at least one row of through holes near the edge along the same, which have a depression on the upper side of the distributor disc for receiving one seed each.
- a distributor housing is arranged on the container, under which the edge of the distributor disk rotates away.
- Under the distributor disc in the area of the distributor housing there is a device for discharging the seeds located in the recesses of the through-holes in distribution lines which lead to a seeding shaft.
- the device includes a plurality of ejector pins whose diameter is slightly smaller than the clear width of the through hole within the distribution disc.
- DE 10 2014 216 370 A1 discloses a rotating conveyor disk of a dosing or sowing unit that has a number of recesses for grain transport.
- the conveyor disk rotates within a housing of a dosing unit for granular material such as seeds, fertilizer or the like.
- the conveyor disk has at least one recess on the outer circumference for accommodating at least one grain to be separated over at least one revolution of the conveyor disk.
- the at least one recess forms a conveying pocket for conveying one grain or several grains in the direction of an outlet opening approximately tangentially adjoining the inner lateral surface.
- the at least one recess is located on the outer circumference the conveyor disk in an insert element which is detachably anchored in the disk.
- EP 3050419 A1 discloses a dosing device of an agricultural machine for the isolated delivery of granular substances in the form of grains, for example seed, fertilizer or the like.
- the dosing device there works according to the differential pressure principle.
- the dosing device includes a housing with grain feed and a seed supply in a chamber.
- the chamber is delimited by a rotatably arranged dosing element with recesses arranged regularly on a cam track for receiving grains.
- the recesses connect the chamber to an area with a lower pressure level. Due to the pressure difference, grains are sucked in by the recesses, which are then conveyed along the cam track to a grain discharge area by rotation of the dosing element.
- a pressure level in the grain delivery area forms an intake air flow, as a result of which the grains experience a change in direction in the direction of a guideway of a guide element in the direction of a seed metering line.
- the grains are actively accelerated by an air flow in the seed metering line.
- US Pat. No. 2,770,440 discloses a solution for a separating device with a conveyor belt
- DE 102004 042 519 A1 discloses a device for wiping off excess seeds from the sowing openings of a single-grain seed drill that are mounted in a rotating drum or disk and are subjected to a pressure difference. It is therefore an object of the present invention to provide an improved device for dosing or individual distribution of material particles, which enables reliable, precise and variable distribution of material particles and at the same time reduces component wear.
- a device for dosing or individual distribution of material particles, in particular seed and/or fertilizer, on agricultural land with at least one storage container which has at least one chamber in its interior for storing a loose bed of material particles, and with at least a separating device protruding into the chamber of the storage container, which has a driven transport means with at least one spoon receptacle for receiving a predetermined quantity of material particles from the loose bed of material particles in the chamber, in particular a single material particle.
- the driven transport means is designed to guide or move the at least one spoon receptacle through the loose bed of material particles (pick-up) and to convey at least one material particle received in the spoon receptacle out of the chamber against the force of gravity (transport), with the at least one spoon receptacle being detachable is connected to the driven means of transport.
- the central invention consists in the simplified separation of the substance particles or the provision in a predetermined quantity (dosage).
- the material particles are picked up from the loose bed and the material particles are transported from the storage container via the separating device to a downstream delivery device in a particularly gentle manner and essentially using gravity.
- the spoon receptacle which is guided through the loose fill, is loaded with the predetermined quantity of material particles, in particular with one material particle, under the action of gravity.
- the at least one particle of matter is accommodated in the at least one spoon receptacle and held by gravity and is conveyed out of the chamber by the transport means up to a predetermined release point.
- the at least one substance particle is passed on to a delivery device, for example under the influence of gravity.
- the device according to the invention basically allows a material particle separation or material particle dosing and distribution without the necessary use of pneumatically operated components.
- a further central idea of the present invention is that the known use of vacuum or compressed air for separating the seed can be dispensed with if this is desired.
- additional pneumatic components in the delivery device ie downstream of the separating device, or parallel to the separating device, thereby enabling at least partially compressed air or vacuum-based distribution.
- dirt particles and foreign bodies in the device for the isolated distribution of material particles can also be discharged to the outside via the discharge device with the aid of compressed air. It is also possible to support the delivery from the separating device to the delivery device using compressed air, vacuum or a combination thereof.

Furthermore, the spoon receptacle can have a spoon-like head area with a recess pointing away from the bottom for receiving (receiving recess) the at least one particle or the defined quantity of particle and a web area for connection to the means of transport.
- the recess can be in the form of a recess (trough) with a recessed bottom surface and an edge at least partially delimiting the recess.
- the recess can also be opened laterally, for example by the edge being interrupted, lowered or the like in the area of the free end.
- the bridge area does not have to be designed narrower or wider than the head area, but can merge flush into it.
- the head area in particular the receptacle, does not have to be arranged axially symmetrically to a longitudinal axis of the web.
- the recessed bottom surface of the receiving recess has at least one through hole for a fluid, in particular air, to flow through the receiving recess.
- a fluid in particular air
- the fluid-supported discharge of the at least one substance particle from the spoon receptacle via the through-hole in turn enables a particularly simple and gentle treatment of the substance particles.
- other fluids i.e. liquids or gases
- seed and/or fertilizer for example liquid fertilizer, which the seed directly previously sowing wetted, liquid or gaseous pesticides or comparable solutions.
- the recessed bottom surface can also be designed with a fluid guide, such that a fluid flow flowing in through the at least one through hole is guided with the fluid guide as a whole or in several partial flows, for example two partial flows, in the receiving recess and thereby the at least one received substance particle in its desired trajectory out of the slot in the spoon mount in the free fall area.
- the fluid guide can be formed by protruding structures on the surface of the recessed base area and in the edge region of the receiving recess, with different shapes depending on the material particles to be received and configurations (with, for example, grooves, elevations, wedge-shaped projections and the like) can be useful.
- the air supply can be supplied by means of a separate device, which can be designed to be adjustable in particular in terms of its relative height and its inclination relative to the spoon receptacle.
- the device can deliver compressed air to the spoon holder, which flows as an air flow at a predetermined angle of attack into the through hole of the spoon holder and, if necessary, is specifically deflected and/or divided inside the holder in order to achieve the desired trajectory of the at least one material particle to be released from the spoon holder out to support.
- the spoon holder can be screwed or clipped to the assigned means of transport.
- the web area can have an external thread or a fastening opening with an internal thread, which is screwed into a corresponding internal thread in a fastening opening of the means of transport or a corresponding external thread (e.g. on a fastening bolt or the like) on the means of transport.
- An analog clip connection (or a comparable, easily detachable type of connection) is also conceivable and enables the spoon receptacle to be easily detachable and connectable to the means of transport.

- the isolated material particles can be deposited or discharged via a common, downstream delivery device or via a plurality of delivery devices each assigned to a transport means or a separating device.
- the at least two separating devices or the at least two transport means can be switched on and off separately, ie in particular the drive of the transport means of the respective separating device can be switched on and off.
- the activation and deactivation can be mechanical or electronically, in particular in a controlled manner. In this way, a specific amount of seed required per area (kg/ha) and/or fertilizer required can be easily calculated and adjusted accordingly.
- each separating device is assigned to a chamber and together with this forms a separating module that can be operated independently of any further provided, respectively different separating modules.
- a common drive which drives all transport means (regardless of the assignment to one or more separating devices) or a common drive for the transport means of a separating device or possibly for the means of transport of a separation module.
- a direct connection to the means of transport or an indirect connection, produced for example via a switchable transfer case, can be provided.
- all transport means of the device or all transport means of a separating device or a separating module can be driven at the same speed by the associated common drive.
- the drive can in turn be driven by a simple roller that runs along on the ground, i.e. e.g. the agricultural area (field), which is driven by a displacement (travel movement) of the device along the ground, so that an additional drive unit can be dispensed with.
- a predetermined ratio between the driving speed of the device when spreading the material particles on a field and the running speed of the transport means (and thus the spreading speed) is predetermined.
- a further conceivable embodiment provides that a common drive takes place via a drive unit, such as a drive motor, and thus drives the means of transport independently of the driving speed of the device.
- a drive can in turn be controlled, for example by means of an electronic control or computer control and/or a mechanical control.
- Such a control makes it possible to adjust the amount of material particles, such as seed or fertilizer particles, while driving.

- the invention can be advantageous to form a plurality of chambers or chamber partitions in the interior of the storage container.
- additional containers for example exchangeable plastic containers
- the chambers can be formed by using suitable partitions.
- the number of dispensing openings provided in the base part of the storage container can be adjusted according to the number of chambers provided, so that, for example, each chamber is assigned a dispensing opening in the base part.
- the at least two transport means of the at least two separating devices can be arranged in parallel, as mentioned above, or offset to one another.
- a common drive can optionally be used, which optionally drives several individual drives of the transport means that can be switched on and off.
- the transport means arranged in parallel are thus driven jointly by one drive.
- the drive can be distributed among several individual drives that can be switched on and off by providing a gear, which enables autonomous control of the individual separating devices and thus means of transport.
- the multiple singulators can be fed from a single chamber or multiple chambers.
- the device can have at least one scraping device, by means of which excess material particles, for example those protruding beyond the spoon holder, can be scraped off into the associated chamber in order to ensure that the specified quantity of material particles is received in the spoon holder.
- a single scraper device can be provided, which can also be useful in the case of several chamber partitions arranged in parallel, or each chamber or chamber partition can have a separate one be assigned stripping element.
- the wiping device can comprise at least one wiping element, which can be designed as a mechanical wiping element which, by mechanical wiping, is able to wipe off excess particles of material that exceed the specified quantity of particles of material to be accommodated in the spoon holder.
- the stripping element can be designed in the form of a brush element, a textile element or an elastic element in the form of a rubber lip, an elastic silicone strip or the like. The elastic deformability of the bristles of a brush element, or of the textile or elastic elements, allows excess material particles to be wiped off particularly gently.
- the stripping device can also include a fluid flow, with the fluid used, for example by means of compressed air, being able to blow off the excess material particles and fall back into the chamber from the spoon receptacle.
- Other fluids may include gases or liquids other than air, as described above in connection with dispensing the particulate matter from the spoon receptacle.
- At least one mechanical scraper element this can act passively, i.e., for example, be fixed at a point where the at least one spoon receptacle moved by the transport means is moved past, and passively brush (scrub) over the moved spoon receptacle.
- the at least one mechanical stripping element can also be driven in order, for example, to carry out a rotating and/or oscillating movement relative to the transport means. Combinations of passive action (for example a freely rotating roller) and active action (which can be driven to oscillate back and forth) are also conceivable.
- the wiping device can also include a plurality of mechanical wiping elements (active and/or passive) and/or a fluid flow in combination with one another.
- a brush element can also be combined with a jet of compressed air as a passive or active mechanical scraper element.
- the number of transport means can be adapt to the number of chambers provided and vice versa.
- the first chamber it is possible that in the first chamber to separate the stored particles of matter by means of a first means of transport and to release them individually and to separate the particles of substance stored in the second chamber by means of a second means of transport and to release them individually.
- the substance particles can be transported separately from one another in the direction of a common or in the direction of separate delivery device(s).
- the substance particles can be deposited in parallel rows or in a common row.
- Particles of the same type can be fed from one and the same chamber of the storage container by means of two independent transport means or, in the case of a non-modular structure, two separating devices.
- the means of transport can be controlled and operated independently of their arrangement relative to one another, either simultaneously or independently.
- the targeted connection or disconnection of a means of transport in a parallel arrangement allows a series disconnection. This makes it possible for the user to selectively store different material particles next to one another, for example different seed types or seed and fertilizer particles.
- the addition of certain material particles and/or the quantity of material particles that are to be deposited in a row can also be regulated.
- the user can define different distances between the individual rows of material particles on the usable area by selectively switching the individual transport and delivery lines on, off or on.
- the spoon receptacles can be fastened to the transport means in the several rows with different distances between the receiving recesses, ie for example the distances between the spoon receptacles in a first row differ from the distances between the spoon receptacles in a second row.
- spoon receptacles can be provided in the individual rows, for example 100 spoon receptacles in a first row and 50 spoon receptacles in a second row and in another row 30 spoon shots. Accordingly, different numbers of material particles can be discharged in the rows of a single means of transport.
- the spoon receptacles can be fixed evenly distributed on a means of transport. If desired, the spoon receptacles can also be mounted unevenly distributed on a means of transport, ie, for example, have different distances from one another in a first row.
- the means of transport can also have only one row with several spoon receptacles.
- the distances between the spoon holders in the individual means of transport can also be chosen to be different, so that, as explained above, the individual means of transport can have a different number of spoon holders.
- the respective application rows can be switched on and off separately. This makes it possible to select a desired row spacing.
- the transport means of the separating device in particular the circulating conveyor belt, is guided over a first and a second shaft, the first shaft in particular comprising a drive shaft and the second shaft in particular comprising a deflection shaft for the circulating conveyor belt.
- the drive shaft can additionally be provided with toothed elements or comparable projection-like structures (nubs or the like) which interact with the transport element or counter-structures formed on the transport element for an improved drive.
- the interaction between toothed elements (or comparable structures) and the counter-structures of the transport element can take place, for example, by at least partial engagement of the toothed elements or comparable projection-like structures in corresponding counter-structures on the circulating conveyor belt, in order to ensure better power and torque transmission between the drive shaft and the transport element.
- the first and second shaft can be arranged on two mutually parallel axes. Alternatively, the axes can be at an angle to each other. Furthermore, it can be advantageous to guide the transport element over more than two shafts.
- one transport element can be arranged to slide on a ring-shaped roller conveyor, the transport element being drivable via a suitable drive element, for example a gear wheel provided with toothed elements.
- the first shaft or the second shaft (or possibly another shaft, for example a deflection shaft) can mark a reversal point or reversal area at which the at least one substance particle accommodated in the spoon receptacle is no longer held in the spoon receptacle by gravity and is in one due to gravity free fall area falls towards the ground.
- the dispensing device comprises at least one distribution channel, which runs from the free-fall area in the direction of the usable area and can optionally be pressurized with air.
- the isolated material particles are released in the direction of the at least one release device.
- the delivery of the substance particles to the delivery device in a defined free-fall area in which the at least one substance particle received in the spoon holder is no longer held in the spoon holder by gravity, but rather falls down due to the force of gravity, ensures that the substance particles of the delivery device fall in a defined Number or be supplied in a defined cycle. This is the only way to enable uniform delivery in the direction of the agricultural area or even distribution of the particles. If several spoon receptacles are arranged on the transport means, uniform or different distances can be provided between the spoon receptacles.
- the material particles lying outside the at least one spoon receptacle of the transport means can be returned to the storage container by means of a return device after being stripped off by a stripping element, wherein the return device can in particular comprise a compressed air duct.
- a stripping element can be provided in the vicinity of the free-fall area, by means of which the excess material particles (for example outside the spoon receptacle) can be stripped off the transport element or the spoon receptacle.
- the wiping element can be designed as a mechanical wiping element (wiping brush, elastic wiping strip or the like) and/or as a fluidically acting wiping element.
- a mechanical stripping element which extends in the vertical direction up to the transport element, this can be in slight sliding contact with the transport element and/or the spoon receptacle connected thereto (passive effect) and/or be actively moved.
- the sliding contact can be formed on the part of the stripping element by plastic and/or textile fringes or elements formed on the stripping element.
- the scraped-off material particles can then be returned to the storage container by means of a return device.
- the return device can be designed as a duct and/or channel, to which a compressed air feed is assigned, as a result of which the material particles in the compressed air flow are returned in the direction of the chambers of the storage container. If several transport means are present, for example, each of the transport means can preferably be assigned a stripping element and a return device. This enables a separate chamber return even when using different material particles.
- the configuration of the spoon holder and the guidance of the spoon holder by means of the transport means can be designed in such a way that in a predefined area in front of the free-fall area, the spoon holder is already inclined in such a way that only the predetermined quantity of material particles or only one material particle is in the Spoon holder can be held by gravity, and a any excess slides off the spoon seat and falls back into the chamber.
- This solution represents a particularly simple and cost-effective variant, in which further components for stripping can be dispensed with.
- the dispensing device comprises at least one distribution channel, which runs from the free-fall area in the direction of the usable area and can be subjected to air pressure. This can open into a number of hoses, which convey the isolated material particles for application to the agricultural area, or a number of channels for a number of hoses can be provided.
- the size of the at least one spoon receptacle can be designed to be adaptable to the size of the (at least one) particle of material to be received, in particular the depth, width and/or length of the receiving recess.
- the spoon receptacle can be designed to be elastically stretchable or mechanically adjustable in terms of its size.
- a mechanical adaptation can be changed by inserting shaped pieces into the spoon holder or screw-induced enlargement or reduction of the recess diameter, based on the principle of a screw clamp.
- the same applies to the adjustability of the fluid guidance inside the spoon holder which can also be designed to be adjustable, for example through the use of inserts. As a result, good individual adaptability of the device to customer requirements can be achieved.
- the separating device comprises a vibration transmitter.
- This may include a device that emits individual air pressure pulses. It is also possible to design the vibration transmitter with a device that enables brief shaking.
- the vibration transmitter is preferably arranged in or on the separating device, so that a vibration or air pressure pulse introduced into it also supports the loosening of excess material particles from the spoon holder and/or the release from the spoon holder into the free fall area.
- the device can be attached to a commercial vehicle, preferably an agricultural vehicle.

- the device 10 is essentially made up of three components: a separating device 20 with a transport means 22 to convey material particles S out of a storage container (not shown), and with a large number of spoon receptacles 24 to remove a predetermined quantity of material particles S , in particular as shown, to separate individual material particles S from a bed of material particles accommodated in the storage container, a delivery device 40 to which the individual material particles S can be passed on and by means of which the individual material particles S are delivered to the agricultural area, and a scraping device 30, to detach excess material particles S from the separating device 20 .
- a compressed air distribution device 60 can be provided.
- the separating device 20 comprises a transport means 22 which, in the embodiment shown, is designed as a circulating transport belt.
- the conveyor belt 22 can, for example, be made of a textile or elastic base material, for example rubber, and have insert elements, for example made of metal or a load-bearing plastic, which are used to stabilize the conveyor belt in the longitudinal direction (for example with steel wires or cables) and to attach the Spoon holders 24 (for example in the form of insert elements arranged transversely to the direction of movement, which are indicated in FIG. 1 with the reference number 22a) are used.
- a transport belt or a transport chain can also be provided, in which case, for example, fastening elements for fastening the spoon receptacles can be provided on the chain links.
- the conveyor belt 22 shown has an inside structure 22b with groove-like depressions between the individual insert elements 22a, which also enables improved transmission of the driving force from a drive shaft 26 to the conveyor belt.
- a counter-structure 26b is provided on the outside 26a of the drive shaft 26, for example in the form of web-like projections which are able to engage in the groove-like depressions of the inside structure 22b.
- the drive of the drive shaft 26 is not shown here. A wide variety of variants are conceivable here, as explained in the general introduction to the description.
- Fastening receptacles 22c can be seen on the outside of the conveyor belt 22, which in the present case are designed as through-holes and are used to fasten the spoon receptacles 24 to the means of transport (cf. also FIG. 2).
- Other design variants are also conceivable, for example threaded holes as fastening mounts, which do not have to be designed to be continuous.
- fastening receptacles 22c are equipped with a spoon receptacle 24 and several rows (two rows in the figures) of fastening receptacles 22c are provided with the same spacing in the circumferential direction of the conveyor belt.
- the assembly of the mounting receptacles 22c is variable and can in this way be adapted to the substance particles to be dosed and separated (seed, fertilizer). Spoon receptacles of different sizes and shapes for different material particles (seed, fertilizer) to be metered and separated can also be detachably attached to the attachment receptacles.
- the spoon mounts 24, have fastening means 24a, 24b in the form of a screw 24a and an insert 24b for fastening them to the means of transport, which are inserted from the inside of the conveyor belt into the fastening mounts 22c and into a corresponding Engage threaded hole 24c on the bucket mount to screw it detachably.
- Alternative detachable attachment mechanisms such as clipping or clipping the Spoon receptacles 24 on or in corresponding attachment structures on the means of transport are of course also conceivable.
- the spoon receptacles 24 include a head area 50 and a web area 52.
- the head area 50 is used to hold the substance particle or particles S (in the embodiment shown to hold a single substance particle S) and has a receiving recess 50a (see FIG. 2) for this purpose. which is dimensioned and shaped in such a way that it is able to hold exactly one single particle S of a certain average size (e.g. a rapeseed grain).
- the recess 50a is delimited by an edge 56 and has a recessed bottom surface 54 in the manner of a trough. The latter has a through bore 58 in order to allow air or another fluid to flow through the receiving recess 50a.
- the size and shape of the receiving recess 50a can vary, which means that the device 10 can be adapted to a wide variety of applications (cf. Figures 4 to 6, here the same features are the same reference numbers are used and deleted one or more times depending on the variant, e.g. 24, 24', 24" and 24'").
- the detachably fastened spoon receptacles 24 can be easily exchanged or their dimensioning of the receptacle recess 50a and/or the through hole 58 or 58′′ can be adjusted by additional inserts 58a (FIG. 6).
- a fluid guide structure 58b is provided by the insert 58a, which achieves a deflection and targeted division of the fluid flow flowing in through the through-bore 58"" (indicated by the two denoted by F arrows in Figure 6).
- This achieves a targeted form of fluid guidance or air guidance within the spoon receptacle 24, which enables the picked-up material particle to be optimally continued.
- spoon receptacles 24 with a laterally open receptacle recess 50a (in which the edge 56 is interrupted or lowered in one area) or with alternative through-holes and fluid-guiding structures can also be used.
- the fluid guiding structure can also be formed directly on the inner surface of the recess 50a of the spoon receptacle 24 .
- the web area 52 is used for connection to the means of transport and has the already described threaded hole 24c at its free end. As in the embodiment shown, it can be narrower than the head region 50, flush with these transitions or wider.
- the spoon receptacles 24 can be made of a metal material, plastic or a combination thereof, for example a metal bar area and a head area made of plastic, wherein the bar area can be cast into the plastic of the head area.
- the transport means 22 is finally guided over a further second shaft 28 which, together with the first shaft 26, tensions the conveyor belt 22 and guides its revolving movement.
- a further second shaft 28 which, together with the first shaft 26, tensions the conveyor belt 22 and guides its revolving movement.
- the arrangement of the separating device 20 in a chamber of a storage container which is used to store a loosened (to be distributed) bulk material particles. It is primarily decisive that the spoon receptacles 24 of the separating device 20 are guided through the bed of material particles in such a way that they are able to receive (can be equipped with) the at least one material particle S in their receiving recess 50 .
- the second shaft 28 can be rotatably mounted or supported as a freely rotating deflection shaft in the chamber, for example via the bearing flanges 28a, 28b, which are attached to the side of this. At the same time, these are dimensioned in such a way that the bucket mounts can rotate freely when assembled. Accordingly, these bearing flanges 28, 28b can also be mounted interchangeably on the second shaft 28 in order to enable adaptability to bucket receptacles 24 of different sizes.
- the angle a (see Figure 7) of the straight line E formed by the two axes of rotation D1 and D2 of the first and second shafts 26 and 28 of the means of transport and the orientation axis of gravity G can be varied. This can be chosen between 0° (perpendicular arrangement) up to 60°, but usually rather up to 45°.
- the orientation of the extension line E influences the acting gravity (which holds the substance particle S in the receiving recess 50a) as well as the ejection point (also the reversal point) at which the substance particle S falls into a free-fall area in which it no longer falls from the spoon socket 24 is supported.
- the trajectory of the material particle S depends on the design of the spoon holder, the speed of movement of the means of transport and the selected ejection point and can also be influenced by the supply of a fluid, for example compressed air.
- a compressed air distribution device 60 is provided for this purpose, which delivers compressed air to the attached spoon receptacles 24 in a targeted manner at the reversal point, which flows through the through bores 58 provided in the spoon receptacles and thus enables improved detachment of the picked-up material particles S and at the same time the trajectory of the material particles S co-determined.
- the compressed air distribution device 60 is arranged in a height-adjustable manner (indicated by the double arrow H in FIG. 7).
- the device 10 also includes the stripping device 30 in order to detach excess material particles S from the separating device 20 .
- this is designed as a mechanical wiper element in the form of a wiper brush. This can act passively in that it is mounted in a stationary manner on a part of the device 10 and drags over the separating device 20 . Alternatively, however, it can also act actively by being moved relative to the transport means, for example by being moved in an oscillating manner transversely to the direction of circulation of the transport belt 22 .
- the device 10 comprises the dispensing device 40, which in the embodiment shown is connected directly to the separating device 20, and two distribution channels 42 with associated ones Distribution hoses 44 has.
- the number of distributor channels 42 and the connected distributor hoses 44 shown are selected purely by way of example and can also include more than two or fewer than two.
- the distributor channels 42 are acted upon by compressed air F, which is blown in via the compressed air supply 46 .
- a suction device can also be arranged in the lower area of the channels or hoses, which creates a negative pressure to support the trajectory of the material particles S.
- the present device enables a simple, reliable and particularly gentle dosing and separation of the most varied material particles, as a result of which the device can be used in a wide range of applications in the agricultural sector.
- Their simple and uncomplicated adaptability enables a very application-specific application of seeds and/or fertilizers, which allows this technology to be used with changing soils or changing soil quality in terms of nutrients, foreign bodies, etc., and to be able to ensure that later over time each seeded plant will receive sufficient nutrients.
- the embodiment shown in the figures represents the invention in a simplified form in order to be able to clearly explain its mode of operation.
- the mechanisms shown can be provided in large numbers depending on the working width of the seed drill.
- a modular structure with different storage containers is conceivable, so that different types of seed and/or fertilizer can be applied at the same time.
- the individual modules can be operated independently of each other and allow a wide variety of applications.
