Description

Device for dropping dropping bodies, in particular seeds and/or seed pellets, and unmanned aircraft with such a device

The invention relates to a device for dropping discarded bodies, in particular seeds and/or seed pellets, and an unmanned aircraft with such a device.

Forests are essential components for the climate and our ecosystem. Due, among other things, to changing environmental influences and human influence, the forest area is constantly shrinking. To counteract this, various projects and options are being undertaken to reforest the forests and/or allow new forests to grow.

Particularly in existing forests, isolated areas with sick and/or dying trees or even bare areas can arise due to the aforementioned influences. Various methods can be used to reforest these areas.

The usual procedure so far is the manual distribution of seeds and/or seedlings to the affected areas of the forest. However, this has the disadvantage that a person has to carry the seeds and/or seedlings and distribute them by hand, making this process time-consuming and costly. What makes matters worse is that the terrain is often not easily accessible, meaning that support with a motor vehicle, such as a car, is only possible to a limited extent or not at all. There are now methods in which seeds and/or seed pellets are dropped by air into a specific area or area. With such a method, a larger number of seeds or seed pellets can be distributed in the area in a short time. However, targeted output is only possible to a limited extent or not at all. Seed pellets are seeds that are surrounded by a shell.

In order to achieve targeted reforestation of areas, unmanned aircraft, in particular multicopters, are used, which fly a container with the seeds or seed pellets to the area and dispense the contents of the container there. Simply tipping a container to empty it may be undesirable. The distribution of seeds or seed pellets should be controlled so that they can be dispensed in a targeted manner. However, the seeds and the seed pellets differ significantly from each other in shape, size and weight. The different shapes, sizes and weights place corresponding demands on a dispensing mechanism for dispensing the seeds and seed pellets.

The prior art is known from CN 208931642 U, CN 110073779 A and DE 12 11 014 B.

It is therefore an object of the present invention to provide a device and an unmanned aircraft with such a device which reduce or eliminate one or more of the aforementioned disadvantages. In particular, it is an object of the present invention to dispense seeds or seed pellets in a controlled manner.

The object is achieved according to a first aspect by a device for throwing off discarded bodies, in particular seeds and/or seed pellets, comprising a receptacle for receiving discarded bodies, wherein the receptacle has a passage opening extending along a longitudinal direction in a bottom section of the receptacle for feeding the discharge bodies to a cylindrical output section. The device further comprises the cylindrical dispensing section with a cylinder base surface and a cylinder longitudinal direction extending perpendicular to the cylinder base surface, the cylinder longitudinal direction extending parallel to the longitudinal direction. The device further comprises a motor which can be coupled to the dispensing section and is designed to rotate the dispensing section about the longitudinal direction of the cylinder, wherein a cylinder surface of the dispensing section has a plurality of depressions and/or a plurality of bristles which are used for receiving and dispensing the discharge body is formed based on the rotation of the output section about the rotation axis.

The depressions and/or bristles on the cylinder surface can accommodate the discharge bodies from a receptacle interior of the receptacle. Particularly due to the weight, the ejection bodies can fall into the recesses and/or between the bristles. If the dispensing section is further rotated by the motor, the depressions and/or bristles move along in the circumferential direction of the dispensing section. From a predetermined angle, the ejection bodies can then fall out of the recesses and/or bristles and can thus be ejected in the direction of a target. Blocking of the dispensing section by one or more of the ejection bodies is reduced, in particular prevented, by the large number of recesses.

The plurality of wells may include one, two, three or more wells. Further, the plurality of bristles may include one bristle, two, three or more bristles. Individual bristles of the large number of bristles can be combined into bundles of bristles. The bristles can consist of animal hair and/or artificially produced bristles. Based on the type, size and/or weight of the ejection bodies, a length, a thickness and/or a stiffness of the bristles can be determined. For example, maple seeds can have wings, and these wings can be particularly easily crushed or damaged. Consequently, it may be necessary to transport and dispense these as carefully as possible. Using the bristles in particular, the maple seeds can fall with their wings between individual bristles, so that the wings are stored stably between the individual bristles. From a predetermined rotation angle, the maple seeds can then be ejected from the bristles due to the weight and/or centrifugal force. At least one or all of the depressions and/or bristles of the plurality of depressions and/or bristles can be designed in such a way that at least one discharge body can be accommodated at least partially, in particular completely, in the respective depression and/or between individual bristles. Alternatively, at least one or all of the depressions and/or bristles of the plurality of depressions and/or bristles can be designed such that two, three or more discharge bodies are each received by one of the depressions and/or the bristles.

The dispensing section can be arranged at least partially in the through opening. The receptacle can be designed to accommodate the dispensing section. Alternatively or additionally, the dispensing section can be arranged and/or fastened on and/or at least partially in the receptacle.

The dispensing section has the cylindrical shape, wherein the shape can have a radius that extends perpendicular to the longitudinal direction of the cylinder. The radius can vary or be constant when viewed along the longitudinal direction of the cylinder, in particular have a predetermined length.

The dropping bodies can be seeds and/or seed pellets, with seed pellets being seeds which are surrounded by a shell. The seeds can in particular be tree seeds. However, the invention is not limited to such.

At least one or all of the plurality of depressions and/or bristles can have at least a predetermined shape. The plurality of depressions and/or bristles may have two, three or more predetermined shapes. The predetermined shape can be determined depending on the ejection bodies. The predetermined shape of the depressions can be hemispherical or, viewed along the longitudinal direction of the cylinder, U-shaped. The shapes of the depressions and/or bristles can be uniform or different. Accordingly, depressions can only be hemispherical. Alternatively, at least one depression of the depressions can be hemispherical and at least one further depression of the depressions can be U-shaped. The plurality of depressions and/or bristles may have a predetermined number of depressions and/or bristles, the number being based on at least one of a predetermined output quantity of the ejection bodies, a power of the motor, a shape, size and/or a weight of the ejection bodies can be determined. Due to the large number of depressions and/or bristles with identical and/or at least partially different shapes, sizes and numbers, different ejection bodies, in particular seeds and/or seed pellets, can be ejected using the device. The depressions and/or bristles can therefore also be dimensioned in such a way that they can pick up and throw off relatively large dropping bodies, in particular seeds and/or seed pellets such as acorns. Particularly when using the device in forest areas, such as for reforestation, the dropping bodies can be significantly larger compared to seeds used in agriculture. Using the proposed device, seeds and/or seed pellets of any kind can be dropped. Viewed along the longitudinal direction of the cylinder, adjacent depressions and/or bristles of the plurality of depressions and/or bristles can be arranged offset from one another in the circumferential direction of the dispensing section. The offset arrangement ensures that the discharge bodies are dispensed continuously and/or uniformly at a constant rotational speed of the dispensing section.

The dispensing section may have only depressions, bristles, or a mixture between depressions and bristles. The bristles can be arranged, in particular glued, on the cylinder surface. Alternatively or additionally, the bristles can be arranged and/or secured within the dispensing section and protrude through predetermined bristle openings. At least some of the bristles can be combined into bundles of bristles.

The receptacle can further have at least one, in particular two brushes in the area of the through opening, which extend in the direction of the dispensing section. The brushes can be designed to be flexible and/or elastic. Furthermore, the brushes can be designed to at least partially press discard bodies picked up by the recesses and/or bristles from the interior of the receptacle into the recesses and/or between the bristles and/or to position them in these. The brush or brushes can be arranged between the receptacle and the dispensing section, such that it is possible to feed the discharge bodies from the receptacle to the dispensing section.

The brush or brushes can each have a brush length and a brush width, with the brush length extending parallel to the longitudinal direction and the brush width extending perpendicular to the longitudinal direction. The brush length may be less than or equal to a through-hole length of the through-hole that extends parallel to the longitudinal direction. Alternatively or additionally, the brush length can be less than or equal to a cylinder length of the output section, which extends parallel to the cylinder longitudinal direction. Alternatively or additionally, the brush width can be determined such that a predetermined brush distance is set between the output section and the brush. The brush spacing can be essentially the same when viewed along the longitudinal direction. The brush or brushes can be arranged in such a way that they are arranged on the receptacle and extend in the direction of the dispensing section. In particular, the brush or brushes can form the passage opening. The receptacle can be funnel-shaped and/or have an inner diameter that tapers in the direction of the through opening. Due to the funnel shape and/or the tapering inner diameter, the discharge bodies fall in the direction of the through opening to the dispensing section due to the weight force.

The receptacle can comprise a motor housing and the motor can be arranged in the motor housing, the motor housing being in particular dust-tight and/or waterproof. Accordingly, muddy ejection bodies or those that are moist due to pickling can be picked up by the receiving container and ejected from the output section without moisture, dust and/or other particles having a negative impact on the motor.

The receptacle can further have a switch box that includes a microcontroller, a voltage distributor and/or a driver for the motor. The motor can be a stepper motor. The switch box can be designed to be dust-tight and/or moisture-tight in order to protect the units located in the switch box from dust and/or moisture. A voltage provided to the motor can be 12V. Viewed along the longitudinal axis relative to the switch box, the receptacle comprises a guide housing, wherein the guide housing comprises a guide section which projects at least partially from the guide housing in the direction of the passage opening. The output section can be arranged on the guide section. Accordingly, the output section is held or stored by the motor, in particular by a motor shaft of the motor and the guide section. The energy or power supply can be provided by an energy source or an energy storage device of an unmanned aircraft, in particular a drone. Alternatively or additionally, the device can further comprise an energy source or an energy storage device which can be arranged in the control box. Alternatively or additionally, the guide section can be provided without a guide housing.

A radial shaft sealing ring can be arranged between the motor arranged in the motor housing and the output section in order to seal the motor in the motor housing when rotation is transferred from the motor to the output section. In particular, a motor shaft of the motor may protrude from the motor housing to rotate the output section. The radial shaft seal can seal the motor shaft so that no moisture, dust and/or other particles get into the motor housing to the motor. The dispensing section may be detachably arranged with the receptacle and/or the motor. Thanks to a modular structure of the receiving container and the dispensing section, a currently arranged dispensing section can be replaced by another dispensing section, depending on the type of discharge body and/or the desired requirements. Consequently, easy handling with flexible use of the device is made possible. The output section can be changed quickly.

The device can further comprise a container attachment, which can be arranged on the receptacle, in particular in a removable manner. The container attachment can be arranged on a side of the receptacle opposite the passage opening. The container attachment can develop a shape of the receptacle, in particular in such a way that it can accommodate a larger amount of discarded bodies. By means of the container attachment, the interior of the receiving container can be enlarged. The container attachment may be in one piece or may have two, three or more container arms extending from the receptacle. At least one connecting wall can be arranged and/or attachable to at least two of the container arms or can be formed between them in order to form a side wall of the container attachment with the two container arms. Alternatively or additionally, at least one connecting wall can be arranged and/or fastened to at least two of the container arms or can be formed between them in order to form a ceiling of the container attachment with the two container arms. The side walls and/or the ceiling can protect the discharge bodies in particular from weather such as rain and wind.

The receiving section can further comprise at least one rail for removably arranging the container attachment on the receiving section, the container attachment having a guide section which is designed such that it can be guided along the rail. The receiving section can in particular comprise at least one, advantageously two piping rails and one or two hinge profiles and the container attachment can comprise one or two pins, which can be arranged in the piping rail and can be guided along it. The rail can be closed at one end section of the rail, so that the container attachment can only be inserted from an opposite end section of the rail. Accordingly, the container insert can be arranged and/or attached to the receiving section easily and quickly. The container insert can also be easily removed. The device can further comprise a scattering and/or collecting device which is arranged in an output direction of the output section and can be arranged on the output section and/or the receiving container. In particular, the scattering and/or collecting device can be arranged below the output section in the direction of the weight force. The scattering and/or collecting device can be designed to scatter and/or collect the throwing bodies issued by the output section and to deliver them in a predetermined throwing direction. The spreading device can be a spreading and/or turntable.

The motor may be operable based on a control signal to rotate the dispensing section at a predetermined rotational speed to dispense a predetermined output quantity of ejection bodies via the dispensing section. The motor can be a stepper motor. In particular, the stepper motor can have a 14:1 gear and/or a speed of 0.1 to 19 revolutions/minute. The motor can have an output of 1 to 5 Nm, in particular 3 Nm. The rotation speed may be determined based on a flight speed of an unmanned aircraft according to the second aspect of the present invention.

The device can further comprise a suspension which can be arranged on the receptacle and is designed to be removably arranged on an unmanned aircraft. The suspension can in particular be designed such that the device can swing due to acting forces such as acceleration by the aircraft. In particular, the device can swing in a dampened manner by means of the suspension, so that the device swings out after a predetermined time.

The dispensing section may include a first and a second cylindrical dispensing section, each of the first and second dispensing sections having a cylinder base and a cylinder longitudinal direction extending perpendicular to the cylinder base, the cylinder longitudinal direction extending parallel to the longitudinal direction. The cylinder bases of the first and second dispensing sections can be arranged parallel to one another. The receptacle can be designed to feed the discharge bodies to the first and second dispensing sections, wherein the motor can be coupled to at least one of the first and second dispensing sections and is designed to rotate the dispensing section(s) about the longitudinal direction of the cylinder. A cylindrical surface of the first and second dispensing sections can each have a first and a second plurality of depressions and / or bristles, which are used to receive and dispense the Ejection bodies are formed based on the rotation of the respective output section about the cylinder longitudinal direction. The output section may include a plurality of output sections as described above, although the number is not limited to two. The plurality of output sections may be three, four or more. The radii of the two output sections, viewed along the longitudinal direction of the cylinder, can vary and/or be constant, in particular have a predetermined length. The first output section can have a different radius from the second output section. Alternatively, the first and second output sections may have identical radii.

The motor may be configured to rotate the first and/or second output portions at a first and a second rotational speed, the first and second rotational speeds being the same or different. Additionally or alternatively, the motor can be designed to rotate the first or second output section, wherein the output section rotated by the motor can be coupled to the other of the two output sections in order to at least partially transmit the rotation of the output section rotated by the motor to the other output section. The coupling of the output section rotated by the motor to the other output section can be done by means of a connecting piece. The connector may comprise a shaft. Alternatively, the motor may include a first and a second motor, wherein the first motor is configured to rotate the first output portion and the second motor is configured to rotate the second output portion. The motor may be configured to rotate the plurality of output sections and/or may include a plurality of motors corresponding to the plurality of output sections. The connecting piece can be controlled mechanically and/or electronically. In particular, the connecting piece can be controllable in such a way that the rotation of the output section rotated by the motor is not or at least partially transmitted to the other output section. Accordingly, in a first dispensing area, the discharge bodies of the first dispensing section or associated receptacle section (see below) can be dispensed by means of the first dispensing section, while the discharge bodies of the second dispensing section or associated receptacle section are not or only partially dispensed, in particular more slowly or less. The discharge bodies of the second dispensing section can then be dispensed in a second dispensing area by connecting the connecting piece through the Motor rotated output section couples to the other output section so that it rotates and outputs the ejection bodies.

The plurality of depressions and/or bristles of the first and/or second dispensing sections may each have a predetermined shape, a predetermined size and/or a predetermined number of the plurality of depressions, wherein the predetermined shapes, sizes and/or numbers of the first and second Output sections are identical and/or different. A dispensing section and/or a receiving container section can be provided for each type of discharge body.

The receptacle can have a first and a second receptacle section. However, the invention is not limited to two and the receptacle may include three, four or more receptacle sections. Each of the first and second receptacle sections can be designed to receive discarded bodies, wherein the receptacle has the passage opening extending along a longitudinal direction or a first and a second passage opening extending along the longitudinal direction in the bottom portion of the receptacle for feeding the discarded bodies from the first and second receptacle sections to the dispensing section or the first and second dispensing sections. The discharge bodies of the first receptacle section can be identical and/or different to the discharge bodies of the second receptacle section. The receptacle can in particular have a partition wall between the first and second receptacle sections for separating the discharge bodies for the first and second receptacle sections. If there are more receptacle sections, correspondingly more partition walls can be provided in order to separate the individual receptacle sections from one another.

According to a second aspect, the task is solved by an unmanned aircraft with a device according to the first aspect.

For further advantages, design variants and design details of the other aspects and their possible developments, reference is also made to the previous description of the corresponding features and developments of the device.

Preferred exemplary embodiments are explained using the accompanying figures as examples. Show it: Fig. 1 is a schematic view of a device for dispensing discarded bodies;

Fig. 2 is a schematic view of a receptacle of the device without a dispensing section;

3 shows a schematic view of the device with an output section according to a first exemplary embodiment; and

Fig. 4 is a schematic view of the device with an output section according to a second exemplary embodiment.

In the figures, identical or essentially functionally identical or similar elements are designated with the same reference numerals.

Fig. 1 shows a schematic view of a device 100 comprising a receptacle 110, an output section 120, a motor 130 installed in a motor housing 116, a suspension 140 and a container attachment 150.

The receptacle 110 is designed to accommodate a large number of discarded bodies, in particular seeds and/or seed pellets. For this purpose, the receptacle 110 shown in FIG. The receptacle 110 further has the container attachment 150 with a plurality of container arms 151, which continue the funnel shape and enlarge a receptacle interior of the receptacle 110. At least two of the container arms 151 can be connected to one another by means of a connecting wall to form a side wall of the container attachment 150 with the container arms 151. The container attachment 150 may have one, two or more side walls. In particular, as many side walls can be formed in order to form a continuous lateral boundary of the container attachment 150. Alternatively or additionally, at least two of the container arms 151 can be connected to one another with a connecting wall in order to form a ceiling of the container attachment 150. The ceiling is arranged opposite the passage opening 111. The side walls and/or the ceiling can protect the discharge bodies in particular from weather such as rain and wind. The connecting walls can be made of a metal, a plastic and/or a clothing material. Alternatively, the receptacle 110 can be one Have a different shape that is suitable as a container. For example, the receptacle 110 may have a base with a bottom portion, with one or more side walls extending from the base to form a container.

The through opening 111 is arranged in a bottom section of the receptacle 110, such that discharge bodies in the receptacle 110 reach the output section 120 through the through opening 111 due to their weight. The through-opening 111 extends along a longitudinal direction (see FIG. 2) with a predetermined through-opening length L. Furthermore, the through-opening 111 has a predetermined through-opening width B, which extends perpendicular to the through-opening length L. The through-opening length and width L, B determine a size of the through-opening 111 and correspondingly a quantity and/or number of discharge bodies that are supplied to the output section 120.

The output section 120 has a cylindrical shape with a cylindrical base and a cylindrical longitudinal direction, the cylindrical longitudinal direction extending parallel to the longitudinal direction. Furthermore, a cylinder length of the dispensing section 120, which extends parallel to the cylinder longitudinal direction, is less than or equal to the through-opening length L. Consequently, the dispensing section 120 can be arranged at least partially in the through-opening 111. Furthermore, the output section 120 is coupled to the motor 130, so that the motor 116 can rotate the output section 120 about the cylinder longitudinal direction. An axis of rotation of the output section 120 therefore extends parallel to the longitudinal direction of the cylinder.

The receptacle 110 is designed such that the dispensing section 120 can be arranged between two opposite side walls of the receptacle 110 and can be removably attached to at least one of the side walls. In particular, the two side walls extend parallel to the cylinder base surface of the dispensing section 120.

As further shown in FIG. 1, a cylindrical surface of the dispensing section 120 has a plurality of depressions 121. Alternatively or additionally, a large number of bristles can be arranged on the cylinder surface. The depressions 121 and/or bristles have a shape and size that is suitable for receiving one or more discard bodies from the receptacle interior of the receptacle 120. In particular, the throwing bodies can fall into the depressions 121 and/or between the bristles due to the weight force. Is the output section 120 through If the motor 130 is rotated, the discharge bodies located in the recesses 121 and/or between the bristles are transported further along the circumferential direction of the dispensing section 120 through the recesses 121 and/or bristles. Due to the acting weight, the ejection bodies fall out of the recesses 121 and/or bristles from a predetermined point along the circumference, in particular after the recesses 121 and/or bristles are at least partially facing away from the interior of the receptacle. Accordingly, the depressions 121 and/or bristles are designed for receiving and dispensing the discharge bodies based on the rotation of the dispensing section 120 about the axis of rotation.

The receptacle 110 further has a switch box 115, which includes a microcontroller, a voltage distributor and a driver for the motor 130. The motor 130 can be a stepper motor. The switch box 115 is dust and/or moisture-tight to protect the units located in the switch box from dust and/or moisture. A voltage provided to the motor 130 may be 12V. Viewed along the longitudinal axis relative to the switch box 115, the receptacle 110 comprises a guide housing 115A, the guide housing 115A comprising a guide section which at least partially protrudes from the guide housing 115A in the direction of the passage opening. The output section 120 can be arranged on the guide section. Accordingly, the output section 120 is held or stored by the motor 130, in particular by a motor shaft 131 of the motor 130 and the guide section. The energy or power supply can be provided by an energy source or an energy storage device of an unmanned aircraft, in particular a drone. Alternatively or additionally, the device 100 can further comprise an energy source or an energy storage device which can be arranged in the control box.

The container attachment 150 has the suspension 140. The suspension 140 is arranged on a side opposite the passage opening 111 and can form part of the ceiling. The suspension 140 extends parallel to the longitudinal axis. The suspension 140 is designed to be detachably arranged on an unmanned aircraft, in particular a (flight) drone. In particular, the suspension 140 is designed such that the device 100 can swing back and forth at least within one plane when arranged on the aircraft. This plane extends in particular perpendicular to the longitudinal direction of the cylinder. The device 100 can swing about an axis of rotation that is parallel to the longitudinal axis. 2 shows a schematic view of the receptacle 110 of the device 100 without the output section 120. As shown in FIG. 2, the motor shaft 131 extends from the motor housing 116 along the axis of rotation to transmit torque from the motor 130 to the output section 120 to transfer. Furthermore, a radial shaft sealing ring 132 is arranged between the receptacle 110, in particular the motor housing 116, and the output section 120 in order to seal a motor housing interior of the motor housing 116 against dust, moisture and other particles. Seed pellets in particular can be muddy and/or wet and the motor 130 should be shielded accordingly.

2 further shows the passage opening width B, which can be less than or equal to a diameter of the output section 120, in particular the cylinder base. 2, the passage opening width B is smaller than the diameter of the dispensing section 120, so that the discharge bodies can fall into the recesses 121 during the rotation of the dispensing section 120.

2, the receptacle 110 further comprises two brushes 112, 112', which extend between the two opposite side walls and along the entire passage opening length L. The brushes 112, 112' extend in the direction of the through opening 111, in particular in the direction of the output section 120. The brushes 112, 112' can have a brush width and a brush length, the brush length corresponding to the through opening length L according to FIG. The brush width extending transversely to the brush length may be determined based on an arrangement of the output section 120 relative to the through opening 111. In particular, the brush width can be selected such that they end at a predetermined brush distance from the output section 120, in particular the cylinder jacket. By selecting the predetermined brush distance, a gap between the through hole 111 and the output section 120 can be determined. The brush spacing can be selected such that the gap is minimal or there is no gap. The brushes 112, 112' can ensure that discharge bodies can only leave the interior of the receptacle via the recesses 121 and/or bristles. The brushes 112, 112' can be designed to be elastic and/or flexible.

The receiving section 110 further comprises at least one rail 113, 113 '(see also FIG. 1) for removably arranging the container attachment 150. The container attachment 150 has a guide section which is designed such that it runs along the rail 113, 113' can be carried out. The receiving section 110 comprises at least one, in particular two, piping rails 113, 113 'and a hinge profile and the container attachment 150 comprises a pin which can be arranged in the piping rail and can be guided along it. This enables the container attachment 150 to be arranged detachably on the receiving section 110.

The following Figures 3 and 4 show embodiments of the output section 120, although the invention is not limited to these. The shape of the depressions 121 can be determined based on the ejection bodies. Furthermore, the shape and a number of the depressions 121 can be determined based on an output quantity of ejection bodies to be dispensed. The depressions 121 can have different and/or the same shapes.

3 shows depressions 121, which have a U-shape when viewed along the longitudinal direction of the cylinder, while FIG. 4 shows depressions 121 with a hemispherical shape. Both FIGS. 3 and 4 show that the recesses 121 are arranged and/or formed offset in the circumferential direction relative to adjacent recesses 121 when viewed along the longitudinal direction of the cylinder. The offset ensures that the discharge bodies are picked up uniformly from the interior of the receptacle and the discharge bodies picked up are delivered uniformly while the rotation speed of the output section 120 remains the same.

By means of the proposed device 100, a uniform and targeted output of ejection bodies is made possible. Furthermore, wedging of ejection bodies is minimized or even eliminated by individual units of the device 100. In addition, due to the modular structure, the output section 120 can easily be replaced by another output section. Accordingly, the device 100 can be configured simply and specifically based on the type and/or shape of the ejection bodies.
