    Machine for mowing staaelartiaem harvest car Description
    The invention relates to a machine for mowing stalk-like crops, comprising a first conveyor and a second crop conveyor downstream of the first conveyor, wherein: the second conveyor comprises a moving element displaceable in motion with recesses for receiving plant stalks in a conveying direction is set in motion, and on the conveying element of the second conveyor a reamer is attached, which cooperates with a mounted in the transition region of the crop between the first conveyor and the second conveyor on the frame of the machine scraper, comprising the planar elements, each extend in a plane extending parallel to the conveying element of the second conveyor level directly below and above the scraper.
    State of the art
    A machine of the type mentioned is described in DE 102 58 013 A1. This machine comprises a number of cutting and conveyor drums which separate the crop standing on a field with lower cutting discs and abfördem with the overlying conveyor discs distributed around its circumference recesses in which the culms of Emteguts be recorded. The Emtegut is then transported alternately in the transverse direction through the backs of the cutting and conveyor drums and by transverse conveyor drums and finally deflected by discharge conveyor drums to the rear and conveyed into the intake duct of a self-propelled forage harvester.
    In order to achieve a proper transfer of Emteguts of the cutting and conveyor drums on the following cross conveyor drums or delivery conveyor drums, the conveyor discs of the cutting and conveyor drums are provided with cuboidal scrapers, which ensure in conjunction with rigidly connected to the frame of the machine scrapers, that downstream of the desired delivery point as little as possible Emtegutmaterial is carried by the conveyor discs of the cutting and conveyor drums. Such scrapers and scrapers are also associated with the transverse conveyor drums and the delivery conveyor drums.
    The scrapers of the cutting and conveying drums arranged in the center of the machine are arranged downstream of the point at which the delivery conveyor drums take over the crop and their leading edges form an outwardly curved surface. The crop is therefore not cleared in the flow direction of the crop from the conveyor discs of the cutting and conveyor drums, but in the tangential direction and downstream of the transfer point to the delivery conveyor drums. Therefore, occasionally accumulations occur at this point, especially when harvesting whole plant silage.
    The transverse conveyor drums extend through slots in the rear wall and their conveyor discs are also provided with scrapers which cooperate with the above and below arranged edges of the slots. Here, a broaching operation takes place over the angular range of the transverse conveyor drums in which they interact with the flow of plant material. Material removal from the circumference of the conveyor discs or scrapers is not provided.
    task
    The problem underlying the invention is seen to improve a machine for mowing stalk-like crop of the type mentioned in that the mentioned disadvantages are avoided or at least reduced. solution
    This problem is inventively solved by the teaching of claim 1, wherein in the other claims features are listed, which further develop the solution in an advantageous manner.
    A machine for mowing stem-like crop comprises a first conveyor and a second crop conveyor arranged downstream of the first conveyor with respect to a crop flow. The first and / or second conveyor can be designed as a drum or chain conveyor. The second conveyor has a movable in motion conveyor element with recesses for receiving plant stalks, which is displaceable in motion in a conveying direction. On the conveyor element of the second conveyor, a reamer is attached to the one in the transition region of the Emteguts between the first conveyor and the second conveyor on
    Frame of the machine attached scraper cooperates, comprising the flat elements, each extending in a plane parallel to the conveying element of the second conveyor plane extending directly below and above the scraper. Furthermore, a frame-fixed side wall element is provided, which adjoins in the region in which the reamer cooperates with the scraper, directly to the enveloping circle of the scraper and extends along the enveloping circle. The conveying element of the second conveyor is thus enclosed upwardly, in the circumferential direction and downwards by the scraper and his scraper closes with the scraper on the three sides mentioned in each case such a narrow column that plant residues are removed from the conveyor disc. In this way, a discharge of Emteguts done by the reamer not only above and below the conveyor element, but also on its circumference, which helps to avoid unwanted accumulation of Emtegut and conveying problems.
    Preferably, one of the planar elements of the scraper also extends into the envelope of the first conveyor. This sheet-like element may have an angled leading edge opposite to the direction of flow in order to actively lift the crop out of the first conveyor and to actively guide it into the recesses of the conveying element of the second conveyor.
    In particular, the scraper is associated with a lowermost conveying element of the second conveyor. The lower surface element is then a bottom element of the frame of the machine.
    In one embodiment of the invention, the first conveyor is a cutting and conveying drum adjacent to a longitudinal center plane of the machine, composed of lower cutting discs and conveying elements arranged above them in the form of conveyor discs with recesses for receiving plant stalks distributed around their circumference, while the second conveyor comprises a with respect to a forward direction and downstream of the first conveyor discharge conveyor drum is arranged, the conveying elements in the form of conveyor discs distributed around its circumference recesses for receiving plant stalks and attached to a conveyor disc clearer comprises. In other words, the scraper is mounted in the gusset area between the cutting and conveying drum and the immediately downstream discharge conveyor drum. In this way, the handover problems observed in the prior art are avoided. However, the scraper according to the invention with the wiper enclosing it can also be used on transverse conveyor drums and with their backs promoting cutting and conveyor drums.
    Working Example
    In the drawings, an embodiment of the invention described in more detail below is shown. It shows:
    1 is a Draufeicht on a machine according to the invention for mowing stalk-like Emtegut,
    2 shows an enlarged detail of FIG. 1 with a delivery conveyor drum and a cutting and conveying drum arranged in front of it, FIG.
    Fig. 3 is a section along the line 3-3 of Figure 2, and
    Fig. 4 is a perspective view of the delivery conveyor drum from the front.
    The machine 10 shown in FIG. 1 for mowing stem-like crops has a number of cutting and conveying drums 12, which are arranged symmetrically to a longitudinal center plane 14 of the machine 10. For reasons of clarity, only one cutting and conveying drum 12 is shown on the left of the longitudinal center plane 14, but in reality there are the same number of cutting and conveying drums 12 on both sides of the longitudinal center plane 14. The cutting and conveying drums 12 are each composed of a lower cutting disc 13 which rotates about a vertical axis and coaxially arranged above conveyor discs 16, which serve as a conveying element and are distributed around the circumference pocket-shaped recesses. The cutting and conveying drums 12 are Halmteiler 18 upstream. Between the back of the cutting and conveying drums 12 and a rear wall 20 of the machine 10, a transverse conveying channel 22 is formed, through which the material harvested by the cutting and conveying drums 12 is transported laterally to the center of the machine 10. The elements of the machine 10 are supported by a frame 17.
    The lateral transport in the transverse conveying channel 22 is supported by transverse conveyor drums 24 rotatably driven about vertical axes. In Vorwärtsbewegungsrichtung V behind the two middle, the longitudinal center plane 14 immediately adjacent cutting and conveyor drums 12 Abgabelfördertrommeln 26 are arranged with respect to the vertical forwardly inclined axes of rotation, serving as a conveyor element conveyor discs 16 the crop from the transverse conveyor channel 22 to the rear into a feed channel 28 of a Forage harvester with feed rollers 30 arranged one above the other. In another embodiment, the cutting and conveying drums 12 and the discharge conveyor drums 26 could also lie in a common plane, which may be oriented horizontally or inclined from above and upwards. The longitudinal center plane 14 adjacent, central cutting and conveyor drums 12 are provided with flat covers 34.
    During the harvesting process, the machine 10 is attached to the feeder channel 28 of a forage harvester and moved in the forward movement direction V over a field. The optionally deflected by Halmteilern 18 stalk-like crop is cut off from the cutting and conveying drums 12 and conveyed into the transverse conveyor channel 22. Due to the conveying action of the back sides of the conveyor discs 16 of the downstream cutting and conveying drums 12 and the conveyor discs 16 of the transverse conveyor drums 24 Emtegut reaches the back of the two central intake and mowing devices 12, where it is deflected backwards. The delivery conveyor drums 26 feed the crop there to the infeed rollers 30 of the forage harvester, chop it and place it on a transport vehicle.
    At the points at which the conveyor discs 16 of the cutting and conveying drums 12 deliver the goods in the transverse conveyor channel 22, stripping elements 36 and 38 are arranged. The stripping elements 36 of the second and third cutting and conveying drums 12 from the inside and the stripping elements 38 of the outer cutting and conveying drums 12 are composed of sheets arranged one above the other, between which stripping slots are formed, rotate through the conveyor discs 16 therethrough. Also on the rear wall 20 of the machine 10 stripping elements 32 are arranged. Similar stripping elements 35 are assigned to the delivery conveyor drums 26 on the discharge side. The outer regions of the conveyor disks 16 of the cutting and conveying drums 12 thus rotate through stripping slots defined between the stripping elements 36 or 38. The stripping elements 36, 38 take the Emtegut out of the recesses of the conveyor discs 16, so that it passes into the transverse conveyor channel 22 and from there into the intake duct 28 and does not rotate continuously with the conveyor discs 16. In order to gradually remove accumulating plant parts in the stripping slots during operation, a scraper 42 projecting upwards and downwards from the conveyor disk 16 is attached to the trailing, approximately radially extending flank of a pocket-shaped recess of each conveyor disk 16. The reamer 42 is an elongated element with a rectangular cross section (see DE 102 58 013 A1).
    Also, at least the lowermost conveyor discs 16 of the delivery conveyor drums 26 are each equipped with a reamer 42. The conveyor discs 16 of the longitudinal center plane 14 immediately adjacent cutting and conveyor drums 12, however, are not provided in the illustrated embodiment with a reamer. The removal of crop from the conveyor discs 16 of these cutting and conveying drums 12 takes place, as shown in FIGS. 2 to 4, by a scraper 44 with a two-part upper element 45, 47, which is arranged between the delivery drums 12 and a central one Guide member 46 in the lateral direction (transverse to the forward direction and horizontally) extends outward. The rear, planar part of the element 45 is located in a forwardly inclined, orthogonal to the axis of rotation of the delivery conveyor drum 26 level and is thus oriented parallel to the plane of the conveyor disc 16 of the delivery conveyor drum 26. The front, flat part of the element 47 is located in a horizontal, to the axis of rotation of the cutting and conveying drum 12 orthogonal plane and is thus oriented parallel to the plane of the conveyor disc 16 of the cutting and conveying drum 12. For this purpose, reference is made in particular to FIG. 4. The element 45,47 extends into the enveloping circle of both the conveyor discs 16 of the delivery conveyor drum 26 and the conveyor discs 16 of the longitudinal center plane 14 immediately adjacent cutting and conveyor drum 12. The element 45,47 is located in the transfer region of the crop of the longitudinal center plane 14 directly adjacent cutting and conveying drums 12 to the discharge conveyor drums 26 and includes a lateral, with respect to the flow direction of the crop leading edge 48 which forms a front nose and is angled from there to the rear and inside. This edge 48 may be straight or, as shown in Figure 4, curved and directs the crop from the longitudinal center plane 14 immediately adjacent cutting and conveyor drums 12 to the discharge conveyor drum 26th
    With reference to Figure 3 it can be seen that the reamer 42 of the lowermost conveyor disc 16 of the Abgabefördertrommel 26 with the element 45 of the scraper 44 upwards and a bottom member 52 of the frame 17 of the machine 10 down each includes such a narrow gap that crop residue by the reamer 42 are stripped off. In the lateral direction, the reamer 42 with a side wall element 53 shown in FIGS. 2 and 4 likewise includes such a narrow gap that crop residue is scraped off by the reamer 42. The side wall member 53 is located in the vertical direction between the bottom member 52 and the members 45 and 47, as shown in FIG. In the forward direction it extends, as shown in Figure 2 by the dashed lines, approximately from the rear end of the element 45 forward to the front end of the element 47. In its rear region, the side wall member 53 extends in the plane of the element 45 and in its front region in the plane of the element 47, ie it is angled in the transition area between. The sidewall member 53 is concave (in plan view) in the region where it cooperates with the reamer 42 of the delivery conveyor drum 26 with a relatively large radius adapted to the enveloping circle described by the reamer 42 of the delivery conveyor drum 26, and therefore closes over sufficient length a fairly narrow gap with the reamer 42, and that at the location of the rotation range of the reamer 42 at the inlet of the discharge conveyor drum 26, on which the reamer 42 also cooperates with the element 45 and the bottom member 52. The size of the gap up, down and to the side may be 2 mm in one possible embodiment. In front of the concave area of the side wall element 53, this is convexly curved toward the front and the inside in the direction of the longitudinal center plane 14. Thereby, the crop is gently inserted into the gap between the side wall member 53 and the conveyor pulley 16 of the discharge conveyor drum 26.
    In this way, one achieves a clearing of the transition region between the longitudinal center plane 14 adjacent cutting and conveyor drums 12 and the delivery conveyor drums 26 and avoids accumulations and conveying problems there. Above the element 45, 47, a laterally projecting guide runner 50 is arranged on the side wall 51, which helps to avoid conveying problems by reducing the gap between the discharge conveyor drum 26 and the side wall 51.
    The illustrated scrapers 44 with upper, lower and lateral, along the circumference extending elements 45,47, 51,52 can also be the take-side assigned to the transverse conveyor drums 16. Also, they can be assigned to the cutting and conveying drums 12 at the locations where they accept crops from the transverse conveyor drums 24 and from the cutting and conveying drums 12 arranged on the outside.
