    Corn cob launcher
    The invention relates to a device for separating and conveying in particular continuously obtained in a harvester plant parts, comprising a conveying element, arranged in the region of one end of the conveying element conveyor fan and arranged in the region above the conveyor blower throw pipe over which the plant parts are conveyed by the conveyor fan ,
    Furthermore, the invention relates to a use of such a device for conveying and separating maize spindles and corn flakes.
    Finally, the invention relates to a method for separating and conveying particularly continuously in a harvester resulting plant parts, in particular of corn spindles, in which the plant parts are conveyed by means of a conveyor blower over a predetermined height.
    Corn spindles, which are gutted corncobs, represent an increasingly popular raw material, which is versatile replaceable. Corn spindles are used as fuel, litter in livestock farming, fall protection for playgrounds and as a raw fiber carrier; In addition, corn spindles can serve as a raw material for the production of fillers and insulants, polishes, oil binders and filter materials. Therefore, in the field of agriculture devices are required, with which maize spindles can be efficiently separated from the bracts, the so-called Maislieschen, and a collection can be fed.
    According to the state of the art, devices for collecting maize spindles are known. US Pat. No. 4,188,160 A describes a device which can be attached to a combine harvester and with which the plant parts ejected from the combine can be conveyed via a pipe into a separate container, for example into a trailer. Preferably, all expelled plant parts are promoted by the device, but by an adjustable baffle can also be made a rough separation of the plant parts. In the case of a maize crop, the separation of the ejected plant parts in corn spindles and maize tufts must be regarded as being inefficient 2, since unwanted maize tubers can be conveyed into the container and maize spindles can be ejected out of the device onto a field.
    EP 2 210 471 A2 describes a self-propelled harvesting device for maize harvesting, 5 in which, during a maize crop, a separation and collection of the maize spindles is to take place. The self-propelled harvester essentially corresponds to a conventional combine harvester, in which, adjacent to devices for separating and collecting corn kernels, a spindle sieve is arranged in an ejection channel, which is intended to bring about a separation of maize spindles and corn flakes. Those maize spindles which fall through the spindle sieve are conveyed by conveyor screws into an external container. In the described Emtegerät is disadvantageous that the necessary for the separation of the corn spindles parts or devices in the central mechanism of the combine and therefore can be attached only in a cumbersome manner. Upgrading or upgrading an existing combine harvester is therefore complex, labor-intensive and cost-intensive. Also, in existing machines rarely required for the corresponding devices space inside the combine is present.
    The invention is therefore an object of the invention to provide a device of the type mentioned above, can be efficiently separated from each other in the course of a harvesting process with the corn spindles and corn or general plant parts and which can be combined with conventional combine harvesters in a simple manner. Another object of the invention is to provide a use of such a device.
    Moreover, it is an object of the invention to provide a method of the type mentioned, with the heavier lighter plant parts, especially corn spindles 30 of corn flakes, can be separated efficiently.
    The first object is achieved in that in a device of the type mentioned at least one air turbine is provided, which generates in a region about 3 the conveying element an air flow to the introduced into the device and falling to the conveyor element plant parts.
    An advantage achieved with the invention is to be seen in particular in the fact that a separation of heavier and lighter parts of plants, in particular of corn spindles and Maislieschen is achieved in an efficient manner, since they have completely different windage surfaces or mass-to-flow resistance ratios. The separation process can be carried out continuously and take place at the same time as the harvesting operation of a combine harvester. In addition, the device according to the invention is relatively easy to attach to agricultural machinery, in particular, the device can be attached to the rear of a combine harvester, where plant parts such as corn spindles and Maislieschen are ejected.
    It has been proven that the air flow generated by the at least one air turbine is directed approximately horizontally. As a result, the air flow is aligned approximately at right angles to the parts of the plant falling to the conveyor element, thereby attacks as best as possible to these and separates the lighter parts of the plant efficiently. In this case, the air flow can be directed in a direction which deviates by an angle between -20 ° and + 20 ° from the horizontal.
    It is advantageous if a sieve is provided in an area above the conveying element, on which fall the plant parts introduced into the device and through which the air flow generated by the at least one air turbine is directed. This provides for a longer residence time of the introduced plant parts in the air stream, the heavier plant parts fall against the air flow through the sieve or grid and the lighter parts of the plant are rejected by the sieve and carried away by the air flow. Overall, there is an efficient separation into lighter and heavier plant parts. Conveniently, the screen is inclined and arranged so that plant parts that do not fall through the screen to the conveyor element, excrete from the device. Thus, heavier parts of plants that fall through the sieve or grid can be collected under this, lighter plant parts such as fast-rotting Maislieschen remain above the screen and can be applied to a field. 4
    In order to achieve a better separation of the plant parts and to avoid clogging or laying of the screen, a drive for shaking the screen may be provided.
    It has been proven that in the area above the conveying element a sliding plate is provided for introducing the plant parts. As a result, a continuous, uniform feeding of plant parts in the course of a harvesting process is possible.
    Conveniently, the conveying element is designed as a screw conveyor. As a result, the separated, heavier plant parts can be fed evenly to the conveyor fan, whereby clogging of the conveyor fan is avoided.
    It is advantageous if the conveyor screw and the conveyor fan are arranged coaxially and their shafts are connected by a rolling bearing. Thus, a connected to a housing, arranged between conveyor screw and conveyor fan support, which would narrow a conveyor cross section can be avoided.
    It has been proven that the device can be coupled to an agricultural machine. So existing agricultural machinery can be inexpensively and easily upgraded or retrofitted. Expediently, the delivery fan, the delivery element and the at least one air turbine can be coupled to an external energy supply, in particular a rotating shaft of the agricultural machine.
    Thus, no separate motors are necessary for operating the device,
    In order to enable ejection of parts of plants into different containers, for example in side-by-side trailers, the throwing tube can be pivotable, height-adjustable and / or foldable. Even a space-saving transport of the device is made possible. It is advantageous if the throwing pipe is hydraulically controlled. This makes a comfortable operation and control of the throwing pipe possible.
    The second object of the invention is achieved in that a device according to the invention for conveying and separating maize spindles and corn flakes is used. 5
    This is an efficient way to obtain a versatile raw material, the maize spindles. In addition, it is advantageous that the device according to the invention can be easily coupled to the combine harvester.
    The procedural object of the invention is achieved in that in a method of the type mentioned an additional air flow is generated and is directed to the incoming parts of plants, so that lighter of heavier plant parts, especially corn from the corn spindles are separated.
    An advantage achieved by the invention is to be seen in particular in that technically simple manner an efficient separation of the incident plant parts is achieved in lighter and heavier plant parts. In particular, the method is successfully applicable to the separation or separation of corn spindles and Maislieschen, since the latter are light and have a large wind attack surface.
    Preferably, the separation of the lighter from the heavier plant parts by the additional air flow before conveying by means of the conveyor blower. Thus, unwanted, lighter plant parts can be ejected before they enter the conveyor fan; only the desired, heavier plant parts are further promoted.
    It has been proven that the additional air flow is generated with at least one air turbine and aligned approximately horizontally. Thus, the air flow crosses the approximately vertically falling plant parts, whereby the lighter parts of plants are efficiently separated out.
    It is advantageous if the lighter parts of the plant, in particular the Maislieschen, are blown away by the air flow and evenly distributed on a floor. Thus, a plowing and subsequent rotting of the lighter parts of the plant is facilitated or accelerated.
    Conveniently, a sieve is additionally used to separate the lighter from the heavier plant parts, in particular the Maislieschen from the corn spindles. In this way, a longer residence time of the falling FTIanzenteile in the air stream 6 and thus a more efficient separation of lighter and heavier Pflanzenteiien is achieved.
    In order to keep the sieve clear and avoid clogging, the air flow can be oriented to pass through the sieve and blow away the lighter parts of the plant, especially the corn fleece.
    It has been proven that the plant parts are conveyed to the conveyor fan with a conveyor element, in particular with a screw conveyor. Thus, a uniform supply of plant parts is achieved in the conveyor fan, clogging of the conveyor fan is avoided.
    Preferably, the additional air flow is generated for separating the lighter of the heavier plant parts in front of the conveyor element and directed to the incident in the direction of the conveyor element plant parts.
    Conveniently, the plant parts are at least partially conveyed by means of a throwing pipe over a predetermined height. Thus, the separated plant parts in different containers, for example, in side-by-side trailers with high conversion or large volume can be promoted.
    Further features, advantages and effects of the invention will become apparent from the embodiment illustrated below. In the drawings, to which reference is made, show:
    Fig. 1 is a perspective view of a Maisspindelwerfers invention;
    FIG. 2 is a front view of a corn cob launcher according to the invention; FIG.
    3 shows a section through a corncob launcher along the line III-III in FIG. 2;
    Fig. 4 is a side view of a Maisspindelwerfers;
    Fig. 5 is a cutaway detail view of a Maisspindelwerfers in the range of conveyor fan and screw conveyor.
    In Fig. 1 is a perspective view of a device 1 according to the invention for the removal and conveying of maize spindles, briefly referred to as Maisspindelwerfer, 7 is shown. For a better illustration of an operation of the device 1, parts of a housing or a lining and a suspension are omitted in FIG. 1 as well as in the following figures. The corncob launcher is designed in such a way that it can be mounted on a harvesting machine, in particular in the rear area of a combine harvester, so that plant parts, in particular corn spindles and corn flakes, continuously occurring in the harvesting machine are introduced into the device 1 or fall into it. The corn kernels are the cored, d. H. Corncobs freed from corn kernels, and cornflakes are the husks of the corncobs. The parts of the plant arising in the combine reach a slide plate 7 of the device 1. The slide plate 7 is arranged in an upper region of the device 1. From this slide plate 7 fall the plant parts in the direction of a substantially funnel-shaped container, at its lowest point a here designed as a screw conveyor element 2 is arranged. The plant parts overcome a drop height in the range of 0.3 to 3 m. In the area between sliding plate 7 and conveying element 2, a sieve 6 is arranged such that parts of plants need to fall through the sieve 6 in order to reach the funnel-shaped container. Next, the sieve 6 is oriented obliquely, so that plant parts that do not fit through the sieve 6, slip on this or slide off and can not get into the surrounding the conveying element 2, funnel-shaped container. In the area under the slide plate 7, two air turbines 5 are arranged, which generate by rotation an air flow which is aligned approximately horizontally and flows through the sieve 6. Thus, plant parts that fall from the slide plate 7 in the direction of conveying element 2, traverse the air flow generated by the air turbine 5. Large and light plant parts with a low mass density and a large wind attack surface are blown away by the air flow generated by the air turbines 5 of the sieve 6, smaller and heavier plant parts with a larger mass density and lower air resistance, however, are hardly deflected by the air flow and reach through the sieve 6 to the screw conveyor. A number of revolutions of the air turbines 5 is continuously controlled and is set as a function of the moisture of the corn spindles and thus their mass. The sieve 6 not only has the function of mechanically separating out parts of plants according to their size, but by its oblique orientation leads to a longer residence time of the plant parts in the air flow generated by the air turbines 5: the parts of the plant falling from the sliding plate 7 slide or slide at a speed which of an 8
    Slope of the screen 6 depends on the sieve 6 down, whereby they are exposed to the air flow; their residence time in the air flow is greater than if they would fall from the slide plate 7 unhindered and in free fall to the conveyor element 2. In the case where the plant parts introduced via the slide plate 7 are corn spindles and corn flakes, the corn flakes are separated from the corn spindles by the sieve 6 and by the air flow generated by the air turbines 5 in the region between slide plate 7 and conveying element 2, the corn flakes are discharged through the air flow from the device 1 and evenly distributed and the corn spindles pass through the screen 6 to the conveyor element 2. The corn spindles are then conveyed by the conveying element 2 designed as a screw conveyor to a conveyor fan 3 and supplied to it continuously and uniformly, whereupon they are conveyed by the conveyor fan 3 via a throwing pipe 4 to a predetermined height, for example ejected into a separate trailer and collected therein.
    FIG. 2 shows a frontal view of the device 1 according to FIG. 1. The viewing direction of the observer is opposite to the air flow generated by the air turbines 5. About the slide plate 7 on the sieve 6 reaching Maislieschen slip on the screen 6 in the direction of the viewer and are blown by the air flow to the viewer or, shipped. FIG. 3 shows a section through the device 1, which leads along the line III-III in FIG. 2. In Fig. 3, the sieve 6 is shown with a kink; in the region of the kink, a hinge may be attached, which divides the wire 6 into two parts. Thus, the lower part of the screen 6 can be designed to be hinged, whereby the conveyor element 2 is easier to access for cleaning.
    In Fig. 4 is a side view of the device 1 is shown. Shown is the page with conveyor fan 3 and throwing pipe. 4
    Fig. 5 shows a section through the device 1 along a rotation axis of conveying fan 3 and designed as a screw conveyor element 2. waves of the conveyor fan 3 and the screw conveyor are arranged coaxially and rotatably connected to a rolling bearing 8 against each other. Thus, conveyor fan 3 and screw conveyor can be operated at different rotational speeds. 9
    By such an arrangement, a support connected to the housing in the area between the conveyor fan 3 and screw conveyor can be saved, whereby a maximum cross-section for the subsidized by the screw conveyor to the conveyor 3 plant parts is achieved. 9 · + * «» »• ·
