    Machine for mowing stalk-like crops with a modular structure
    feed drum
    description
    The invention relates to a mowing and intake device for a machine for mowing stalk-like crop, with a lower cutting disc for cutting Pflanzenstängein and arranged above, displaceable by a drive shaft about a substantially vertical axis in rotation, mutually vertically spaced conveyor discs with around the circumference distributed recesses for receiving and removal of Pflanzenstängein, between each of which areas of a drum shell are arranged.
    State of the art
    Machines of the type mentioned above are used in particular for corn crop. The plants are separated by mowing and collection devices on the one hand from their roots and on the other hand recorded and carried away. These mowing and collection devices comprise lower cutting discs for cutting the plants and conveyor discs arranged above them with recesses for receiving plant stem distributed around their edge. There are a certain number of conveyor discs arranged one above the other, usually three or four. So far (see DE 296 13 397 U1) such conveyor discs are manufactured as so-called feed drums, which consists of a lower conveyor disc, a coaxially arranged above, by welded joints on the conveyor disc mounted cylinder and welded to the cylinder rings, which mentioned above Conveying discs form with distributed around the edge recesses. The lowermost of the conveyor disc extends radially inwardly from the drum shell and serves for connection to a central drive shaft, which projects upwards from a gear arranged below the mowing and drawing-in device. Above the cylinder a cover is attached. The lower cutting disc usually rotates faster than the feed drum and separates the plant stems in the free section, although embodiments are known to rotate at the same speed as the feed drum and with fixed counter cut edges cooperate (DE 10 2007 038 276 B3).
    These catch drums are therefore welded assemblies, which are relatively complex due to the many required welding joints in the production. Another
    Disadvantage is that in case of damage to one of the conveyor discs, e.g. When hitting an obstacle or in case of heavy wear, a repair of the catch drums is quite complex, because due to the total welded construction, an exchange of items is not readily possible. Instead, it is usually necessary to replace the entire feed drum, which causes relatively high costs.
    task
    The object underlying the invention is seen to provide a mowing and intake device for a machine for mowing stalk-like crop, in which the above-mentioned disadvantages of the prior art do not occur or to a lesser extent. solution
    This object is achieved by the teaching of claim 1, wherein in the other claims features are listed, which develop the solution in an advantageous manner.
    A mowing and intake device for a machine for mowing Stängeless Emtegut is arranged with a lower cutting disc for cutting plant stems and arranged above, by a drive shaft about a substantially vertical axis in rotation displaceable, mutually vertically spaced conveyor discs with distributed around the circumference recesses for Receiving and discharge of plant stems equipped, between each of which areas of a drum shell are arranged. The conveyor discs are each formed with a radially inner portion, a central, cylindrical and the axis of rotation coaxial portion, each forming a part of the drum shell, and a radially outer, provided with the recesses for receiving and promoting plant stems section. The radially inner portions are releasably connected to each other and coupled directly or indirectly to the drive shaft.
    In other words, the previous, welded feed drum is replaced by a modular system consisting of several in particular deep-drawn conveyor discs. These conveyor discs each comprise a radially outer portion with the recesses for receiving the plant stems, a central, approximately vertical and coaxial with the drive shaft extending, cylindrical portion which forms a part of the drum shell, and a radially inner portion which releasably with the radial inner portions of the other conveyor discs and is connected to the drive shaft.
    In this way, the conveyor discs can be removed and replaced after damage or excessive wear, which greatly simplifies repair. In addition, it is possible to reduce individual conveyor discs if necessary, if they are not required for each crop to be introduced, and / or to replace them by conveyor discs with other dimensions or properties (height, diameter, number of recesses, etc.).
    The radially inner portions are preferably directly adjacent to each other, i. they form a kind of sandwich. It would also be conceivable to install between them washers or other spacers.
    The radially inner portions of at least some (or all) of the conveyor discs may be completely flat (down to the central portion). In particular, a lowermost conveyor disc may, however, be curved downwards at a radial distance from the attachment point of the conveyor discs.
    The parts of the drum shell formed by the middle sections of at least some (or all) of the conveyor disks can each have at least approximately the same diameter. However, the part of the drum shell formed by the middle section, in particular of the lowermost conveyor disk, can have an enlarged diameter compared with the other parts of the drum casing.
    The central portion of a first (especially uppermost) conveyor disc may be located within the middle portion of an adjacent, second conveyor disc.
    The conveyor discs are made in particular as deep-drawn elements, although they could also be designed as welded assemblies.
    Ausführunasbeisoiel
    In the drawings, an embodiment of the invention described in more detail below is shown. It shows:
    Fig. 1 is a plan view of a machine for mowing stalk-like crop, and
    2 shows a section through the machine along the line 2-2 of Figure 1.
    1 shows a plan view of a machine 10 for mowing stalk-like crop. It comprises a support frame 14, which for harvesting operation is attached to a feeder channel 12 of a forage harvester (not shown) which moves the machine 10 in a forward direction V across a field. In the illustrated embodiment, the machine 10 comprises a total of eight mowing and collecting devices 16, which cut off and convey away the plants standing in the field. The transverse transport of the plants takes place through the rear sides of the mowing and intake devices 16 in combination with transverse conveyor drums 18 and finally the plants are deflected by discharge conveyor drums 20 to the rear into the intake channel 12. The machine 10 could include a larger or smaller number of mowing and collection devices 16 whose diameter (here about 75 cm corresponding to a conventional row spacing) could also be greater than shown.
    FIG. 2 shows the structure of a mowing and drawing-in device 16 and of the transmission 22 serving for its drive. A transverse shaft 24 arranged in a carrier of the supporting frame 14 drives an input shaft 26 via a bevel gear, which via a further bevel gear 28, 30 forms a shaft 32 drives, which via a further gear pair (not shown, but but DE 296 13 397 U1) drives a hollow shaft 36 to which a lower cutting disc 38 is mounted. This is used to cut the plant stems in free section. In another embodiment (not shown), however, the cutting disc 38 could rotate with the conveyor discs 46, 48, 50, 52 of the mowing and retracting means 16 and cooperate with a stationary counter-blade.
    The input shaft 26 drives via a further bevel gear (not shown, see DE 296 13 397 U1) to an approximately vertically extending drive shaft 34 which extends through the hollow shaft 36 upwards and to drive the conveyor discs 46, 48, 50, 52nd the mowing and intake device 16 is used. The drive shaft 34 is connected to an upper shaft portion 40, which in turn is connected by fastening means 44 with holding means 42. The holding means 42 are designed here as a flange plate, which is positively coupled and thus torque-transmitting with the upper shaft portion 40, e.g. in that the upper shaft portion 40 is toothed and conically shaped and the holding means 42 are pressed onto the upper shaft portion 40 by the fasteners 44 designed to cooperate with an upper thread of the upper shaft portion 40. It would also be conceivable, the conveyor pulleys 46, 48, 50, 52, instead of indirectly coupling with the upper shaft portion 40 as shown here by the holding means 42 to connect directly to the upper shaft portion 40 torque transmitting, in particular by positive engagement.
    The holding means 42 are used for mounting a total of four conveyor discs 46, 48, 50, 52. The upper three conveyor discs 46, 48, 50 each comprise a flat, radially inner portion 54, a central, coaxial with the drive shaft 34 extending, cylindrical portion 56th forming a part of the drum mantle of the mowing and drawing-in device 16, and a radially outer section 58 forming a ring provided with recesses 61 (see Figure 1) for receiving and discharging plant stalks. The middle portion 56 of the uppermost conveyor disc 46 engages in its lower region in the central portion 56 of the underlying conveyor disc 48 a. The middle portions 56 of the two upper conveyor discs 46, 48 extend from the radially inner portion 54 upwards. The middle portion 56 of the third conveyor disc 50 extends downwardly from the radially inner portion 54. The central portions 56 of the upper three conveyor discs 46, 48, 50 have approximately the same diameter. The lowermost conveyor disk 52 has a central, inwardly flat part 54, the diameter of which corresponds approximately to that of the holding means 42. Radially outside this flat part 54, the lowermost conveyor disc 52 is curved downward and forms a central portion 56 which has a larger diameter than the central portions 56 of the upper three conveyor discs 46, 48, 50. Also, the outer diameter of the radially outer portion 58 of the lowermost conveyor disc 52 is greater than that of the upper three conveyor discs 46, 48, 50. The cavity formed by the uppermost conveyor disc 46 is closed at the top by a cover 64. The conveyor discs 46, 48, 50, 52 are produced in particular by deep drawing.
    The radially inner portions 54 of all three conveyor discs 46, 48, 50, 52 are flat and lie directly above each other. They are fixed by screws 60, which extend through corresponding holes or bores in the radially inner portions 54, and nuts 62 on the holding means 42. Thus, it becomes possible, after removing the cover 64 and the fastening means 44, all pulleys 46, 48, 50 and 52 decrease together from the shaft portion 40 and after disassembly of the nuts 62 and screws 60, the conveyor discs 46, 48, 50, 52 from each other to separate To replace a damaged or worn conveyor disc against a new conveyor disc. The assembly takes place in reverse order.
    In addition, the modular design provided according to the invention makes it possible to dismantle one or more of the conveyor disks 46, 48, 50 or 52, if it were not necessary for a particular application, e.g. in the whole plant silage harvest, or by a conveyor disc of other shape, dimensions or the like to replace. Furthermore, one of the conveyor discs 46, 48, 50, 52, in particular the second conveyor disc 48 from above, could be completely flat in itself, i. the middle section 56 is omitted.
