    Device for injection of fertilizer
    Description The invention relates to an injection device with a liquid fertilizer, with which the fertilizer can be converted quickly and safely into a substrate for supplying nitrogen to crop plants.
    Description of the invention In the case of the introduction of a fertilizer for the supply of nitrogen to crop plants, the fertilizer is not applied flat in contrast to conventional methods, or is applied extensively, but with the aid of an injection technique of 7 to 20 cm inserted deep into the soil next to the seed. Various injection techniques are used for this.
    For example, an injection technique is known from the description DE 102004028291 A1 in which a number of devices are arranged next to each other, and wherein the fertilizers are introduced into the soil at intervals and approximately vertically and remain in the soil during the further movement of the trigger for a specific time unit. To this end, the injection device and the wheels of the device are designed as separate components. However, the injection devices are functionally connected to at least one wheel such that the roller makes the desired vertical grooves and allows a modern and sufficient supply of the liquid fertilizer. However, a disadvantage of the apparatus is that the fertilizer injection is implemented using a technique that is susceptible to malfunctions and therefore only less suitable for operating it in agriculture.
    Another type of depot fertilization injection device is described in the document DE 10 2008 027 064 A1, in which a single wheel of such a device is described. A larger number of injection needles (spokes) are hereby arranged in a wheel shape with the same angle intervals. When the wheel is rolled, the irijection needles regularly spray into the soil and a certain amount of the liquid fertilizers can be deposited in soil depots. The projection of the injection needles over the tread of the wheel determines the depth of the injection into the ground. In this way fertilizers can be optimally introduced into the environment of the root ball of the plant, depending on the crop plant. Another form of the embodiment is described in the document DE 10 2011 079 290, wherein the injection needles have a substantially flat shape to simplify the penetration into the terrain.
    In the known injection devices of the prior art, a number of injection wheels are arranged side by side on an arm by means of a respective pivotal arm. A device has a number of pivot arms that are usually transported in the vertical position and used in the horizontal position. The swivel arms are moved to the horizontal working position by turning it, often by means of a folding joint. However, other folding variants are also known from the prior art, for example also parallel to the direction of travel of the vehicle. In the case of a substantially vertical transport position, it is also observed that the dirt which adheres to the wheels falls on the pivot arm which is arranged underneath and penetrates into the hub or other essential components of the pivot arm.
    The aforementioned technology can be referred to as one that is generic to the present description, but has a number of certain shortcomings. This also regularly leads to further contamination, as a result of which both the walking behavior of the swing arm and the fertilization result change. Since, for example, to prevent contaminated surfaces, no lubricants should escape from the hub, because the dirt then penetrates the hub and sometimes leads to the wheels sticking. Contaminants that penetrate the injection needles, for example while driving curves, can reduce the emission behavior of the manure, so that too little fertilizer is applied and introduced into the soil. The different amounts of fertilizers can cause errors that therefore have a direct effect on the harvest result. The contamination of the injection wheels is accompanied by increased wear, such that the device must be serviced or renewed quickly.
    Embodiment of the Invention It is therefore the object of the invention to provide a device for fertilizer injection, wherein the sensitivity to contamination of the device is reduced or even prevented.
    This object is achieved by means of a fertilizer injection device which has an encapsulated space in the interior of the hub in which the lubricants required for rolling the injection wheel are present, and there is also a leakage space through which the fertilizer from the supply line of the hub.
    The prior art fertilizer injection devices are generally for an agricultural implementation or a following tracking unit for this purpose. At least one segment is mounted on at least one inside swivel arm that is mounted on the agricultural device or the following tracking unit. At each segment, a number of wheels with their hubs are placed side by side via the wheel arm. The running wheels each have a number of fertilizer injection needles around their treads. Each injection wheel has a connection for a supply line from a fertilizer tank.
    The hub is secured by means of a clamp on the wheel arm, which consists of a stator and a rotor with a round wheel with the injection needles. The stator has a transfer ring to which the supply line is connected. The transfer ring has a circular transfer slot. This transition slot is positioned in the installed state such that it occupies the lowest position on the circumference of the circle.
    A transfer ring is provided on the rotor which has a plurality of packed sleeves for the transfer. The transfer sleeves are connected to the injection needles via fertilizer pipes. The liquid fertilizer is discharged into the stator at the connection of the supply line and reaches the transfer slot by means of the transfer ring. For the transfer ring, the transfer ring rotates with the built-in transfer sleeves, which are connected by hoses to the injection needles on the injector wheel disc. The liquid fertilizer comes from the injection needles.
    In order to allow the liquid fertilizer to be discharged only when the injection needle is in the soil, the arrangement and geometry of the transfer slot or of the transfer expansions are chosen such that the transfer forms overlap the transfer slot for a part of a certain arc length. The arc length depends on the selected number of injection needles. The transfer slot is positioned such that the transfer reserve exceeds its length for the injection needles belonging to the respective transfer recess placed in the ground, generally around the lowest point of the stator.
    During the above-described discharge of the fertilizer for fertilization purposes, a further outlet according to the invention is provided. To this end, fertilizer is released in the leakage, which does not reach the hub laterally through the injection needles. With this intended leakage, also the area of the hub, into which contaminants can penetrate, is constantly freed from the contamination by means of small quantities of liquid fertilizers and therefore does not form an obstacle to the smooth rolling of the wheel.
    In a particular embodiment of the device according to the invention for the fertilizer injection, the space for transferring the fertilizer from the supply line to the outside is provided by means of a labyrinth ring. Thus, on the one hand, only a very small amount of impurities can usually penetrate into the hub, and on the other hand, the required amount of fertilizer released into the leakage chamber in the hub is reduced to a required minimum.
    In a further special embodiment of the device according to the invention for fertilizer injections, the transfer of the fertilizer from the supply line to the leakage of the hub takes place only very sporadically. Since the manure is transferred through the supply line through the supply line to connect it to the hub, in the case of a point-wise transfer from the stator to the leakage space between the stator and the rotor, the amount of means intended to to be flushed down. A further reduction occurs when, in a further embodiment of the fertilizer injection device, the transfer of the fertilizer from the feed line into the leakage of the hub is generally carried out only once per revolution of the impeller.
    To further facilitate the transfer of the manure used to flush the hub of the stator to prevent leakage of the hub, a leak slot is provided which sweeps over the transfer lock in a further particular form of the device for fertilizer injection. This embodiment provides an even better and even faster transfer of a suitable amount of fertilizer from the supply line to the leakage space of the hub to flush it.
    In order to further reduce the contamination of the fertilizer injection device, in one embodiment of the swing arm or the segments of the swing arm, the latter comprises protective plates covering at least one injection wheel. The dirt particles that have been worked up by the device during field processing are thus prevented from spreading and which will result in less dirt penetrating the hubs.
    In a particular embodiment of the device as set forth according to the invention for fertilizer injection, the protective plates are arranged such that they can be rocked in the plane of the fan. For example, damage or even breakage of the protective plates can be effectively carried out, for example during transport. It is advantageous if the protective plates are made of a robust, but elastic plastic or otherwise of metal, to absorb the impact. The cleaning of the device by means of a high-pressure cleaner or in an associated installation can therefore be carried out without problems.
    In a further embodiment of the fertilizer injection device, a fertilizer tank is arranged on the trailer unit. On the one hand, an improved amount of the fertilizer that can be applied simply can be provided by the arrangement on the trailer. On the other hand, this control also improves the performance of the follower unit, because the increased weight of the fertilizer tank considerably reduces the swing of the follower unit when the inner swivel arms are folded out.
    According to a further embodiment of the fertilizer injection device, the fertilizer tank is arranged in such a way that the pivot arms can generally be folded substantially horizontally above this fertilizer tank. The drive characteristics are further improved by a very deep arrangement of the fertilizer tank. In addition, contaminants are reduced which remain with the use of the runners during such storage of the vibrating arm during transport, for example by a jumping up and down during transport or during the rain. However, the contaminants do not pass through the hubs or elsewhere in the injection wheels during this storage, but fall to the ground.
    Subsequently, in a further embodiment of the device according to the invention for fertilizer injection, it is provided that the inner swivel arm is arranged such that it can rotate about a substantially vertical axis opposite the agricultural vehicle or the follow-on unit. This ensures that, for example, there is no "plowing" during the bends over the agricultural surface with the injection needles, but also in this case a substantially uniform uniform rolling takes place. This contributes to the prevention of contamination of the device.
    To illustrate the apparatus as set forth according to the invention for fertilizer injection, drawings are attached to the description.

    The basic construction of the generic fertilizer injection device (1) is shown in Figure 1 in a plan. It is designed as a trailer for a tractor and therefore has a tractor device (2). A fertilizer tank (3) is provided on the device (1) for the fertilizer injection. In the transport condition shown, the inner swivel arms (4) can be seen, on which the external swivel arms (5) are arranged. The inner and outer swivel arms (4, 5) support the injection wheels (6). In addition, means (7) are provided for folding the internal swivel arms (4) with which the inner swivel arm (4) can be transferred from a transport position to a working position.
    The operating condition of the generic fertilizer injection device (1) is shown in Figure 2, and shows the operating position of a follower unit. A pulling device (2) is also present here. The swivel arms (4, 5) are laterally unfolded with the aid of the means (7) for folding the inner swivel arm (4). The outer swivel arm (5) is mounted on the inner swivel arm (4). The segments (29) with injection wheels (6) are arranged on the swivel arms (4, 5). The fertilizer tank (3) and a pump (8) are provided for the following filling unit, wherein the fertilizer is pumped from the fertilizer tank (3) to the injection wheels (6). In addition, the vehicle wheels (9) are recognizable.
    The interplay of the inner and outer pivot arms (4, 5) is visible in Figure 3, showing the device (1) for fertilizer injection in the level of uneven terrain from the rear. Because the outer pivot arms (5) are designed to be rotatable relative to the inner pivot arms (4) and are pivotable relative to the vehicle, the pivotally suspended segments (29) fit together with the combined injection wheels (6) through their rotor arms (10) optimally on the terrain.
    Figure 4 shows how a device (1) for the injection of fertilizer during transport can look in front of the view. In order not to exceed the maximum permitted width of a vehicle on public roads, the swivel arms (4, 5) are also adjusted upwards by means of the means (7) for folding the inner swivel arm (4, 5) upwards the vehicle wheels (9).
    In order to reduce the contamination of the fertilizer injection device (1) and to improve the turn-through characteristics, this device is provided with a substantially vertical axis of rotation (30) with which the inner swivel arms (4) can rotate relative to the vehicle. When taking a bend, as shown in figure 5, the trailer not only pivots out towards the tractor, but a further rotation is also carried out of the inner swivel arm 4 and therefore also of the outer swivel arm 5 and of the injection wheels 6 against the follower unit, so that even smaller curved turns can be taken, and driven without the injection needles being considerably contaminated on the injection wheels (6).
    In figures 6 and 7, an injection wheel (6) is shown in a first view. The injection wheel (6) is attached to the swivel arm (4, 5) by means of a wheel arm (10), which is not further shown. The wheel arm (10) carries a protective arm (12) on which a protective plate (11) is mounted such that the injection wheel (6) functions. The injection wheel (6) has a hub (13) through which the shaft (14) moves over the rotor. The injection wheel (6) is characterized by a wheel surface (17) and a wheel disc (18). While the wheel disc (18) has essentially stability reasons, the wheel surface (17) serves as a support for the injection needles (15) connected to the fertilizer lines (16) and to the hub (13).
    In Figure 8, the hub (13) is shown in more detail. The expanded drawing shows the two-component rotor (19) and the stator (20). Transfer sleeves (21) are provided on the rotor (19), to which the manure lines (16) (not shown in the figure) are attached. The transfer sleeve (21) is connected by means of a liquid transfer to the transfer sleeve (22), a transfer output (22) being assigned to each transfer sleeve (21). Moreover, the take-over lock (25) according to the invention can be seen in the rotor (19), which ensures a transfer of the manure into the leakage chamber (26). The rotor (19) also has the lubricant chamber (27), which contains the lubricant required for the proper roll of the injection wheels (6). The rotor forms part of a labyrinth ring (28) through which the fertilizer comes out of the hub. Provided on the stator (20) is the supply line connection 31 which is connected to the fertilizer tank (3) by means of a liquid connection.
    The illustration in Figure 9 shows the same hub also in an expanded view, but from a different direction. The transmission sleeves (21) are mounted on the rotor (19). The stator has a transfer ring in which a leakage slot (25) is placed. The latter is positioned so that it is regularly swept by the transmissions (22) arranged in the rotor (19) and the leak slot (25) in the rotor (19) when the injection wheel (6) is unwound. During sweeping, the manure is discharged from the stator (20) into the rotor (19) and used for cleaning the hub. The stator (20) comprises the other part of the labyrinth ring (28), which corresponds to the part of both halves arranged on the rotor (19) that come together.
    In figure 10 the hub (13) is shown even more accurately. The exact construction of this embodiment can be clearly seen through a section. The hub (13) comprises a stator (20) and a rotor (19). Both stator (20) and rotor (19) have corresponding labyrinth rings (28). A supply line (31) is provided on the side of the stator (20). The fertilizer is hereby passed on to the hub (13) for further use. After the hub (13) penetrates, the fertilizer flows through the transfer ring (23) to the transfer slot (24). As a transfer sleeve (21) passes through the transfer outlet (22) at the transfer lock (24), the fertilizer is passed to the injection needles (15), which is not shown. At regular intervals, the leakage slot (25) also overflows the transmission slot (24). In this case, a small amount of manure is released into the leakage chamber (26), which then comes out via the labyrinth ring (28). The lubricant chamber (27) is provided with a seal (32) separately from the leakage chamber (26). A detail of X is shown in Figure 11.
    A detailed view X of Figure 10 is shown in Figure 11. In this view, the leakage slot (25) simply sweeps over the transmission slot (24). The fertilizer enters the leakage chamber (26), which is separated from the lubricant chamber (27) by means of a seal (32) and completely surrounds the axis of rotation of the rotor (19). From there the manure flows through the labyrinth ring (28) until it goes out. Between the rotor (19) and the stator (20), the impurities between the rotor (19) and the stator (20) are removed from the rotor (19) and the stator (20).
    Since the foregoing fertilizer injection device described in detail herein is an exemplary embodiment, it can be modified by a person skilled in the art in a conventional manner without departing from the scope and scope of the invention. In particular, the concrete embodiments of the hubs can also be described in a different form within the scope of the invention. The protective protection plates can also be designed in a different form, if this is necessary for technical, structural or design reasons. Moreover, the use of the "indefinite" one-on-one articles does not exclude the fact that the relevant functions may also be present several times.
