harvesting header 10 illustrated in fig1 is suitable for harvesting corn , sunflowers , and other plants with stalks . the harvesting header 10 includes eight similar type collection devices 12 , 14 and 16 , which are arranged in line one next to another with corresponding picking devices and which are used for collecting plants . the picking devices separate the fruit from the plant . the picked fruit is directed to a cross auger 20 arranged at the rear of the collection devices 12 , 14 and 16 to a center feed opening 18 . from the center feed opening 18 the harvested fruit is directed to a feeder house of a combine . the unharvested plant residue is chopped up or returned as a whole on the field . the collection devices 12 , 14 and 16 include grippers rotating about a horizontal axis , which grip the plant stalk and transport it over the length of the picking gap , where the plants are pulled downwards through interacting stalk rolls . the design of the individual collection devices is described in de 101 51 198 , whose publication is also cited . the collection devices are asymmetrical relative to their longitudinal center plane because the picking gap is arranged at the side next to the feed auger . the harvesting header 10 can move between an operating position , as illustrated in fig1 and a transport position . each of the two outer collection devices 14 and 16 and the outer parts of the cross auger 20 are fixed to the outer frame sections 22 . the outer frame sections 22 are hinged to a center frame section 24 so that the outer frame sections can pivot about horizontal pivot shafts 26 running in the direction of travel . the center frame section 24 carries the center collection devices 12 . hydraulic pivot cylinders 28 are used to fold the outer frame sections 22 about the center frame section 24 . the hydraulic pivot cylinders 28 are hinged on both sides of the longitudinal center plane of the harvesting header 10 to the center frame section 24 and are connected by coupling assemblies 30 to the outer frame sections 22 , the outer frame sections 22 can fold upwards and inwards about the pivot axis 26 . the coupling assemblies 30 allow the outer frame sections 22 to be laid over the center frame section 24 when in the transport position . thus , in the transport position , the outer collection devices 14 and 16 are located above the inner collecting and picking units 12 . in this way , the combine can join street traffic without having to remove the harvesting header 10 from the feeder house and loading it onto a wagon or the like . between each adjacent collection device 12 , 14 and 16 and at the outer sides of each outermost collection device 14 and 16 , there are separating points 32 , 34 , 36 and 40 mounted in the direction of travel in front of the collection devices 12 , 14 and 16 . they are used to deflect the plants to the side , so that the plants can be gripped by the grippers of the collection devices 12 , 14 and 16 and pulled into the picking gap . if the separating points 34 and 40 arranged between the center frame section 24 and the outer frame sections 22 were attached rigidly to the center frame section 24 , they would define the transport width of the harvesting header 10 . if the operating width of each of the individual collection devices 12 , 14 and 16 is 0 . 75 m , acceptable transport widths , which are currently equal to 3 . 5 m in germany , can be maintained either only with difficulty or not at all . in addition , there is the risk of collision between the collection devices 14 and 16 and the separating points 34 and 40 when the outer frame sections 22 are pivoted upwardly and inwardly . for these reasons , the separating points 34 and 40 are mounted so that they can move laterally . the separating point 34 arranged on the left edge of the center frame section 24 with reference to the direction of travel is pushed to the right from the position illustrated in fig1 when the harvesting header 10 is brought into the transport position . it is attached to the center frame section 24 . the separating point 40 arranged in the direction of travel directly to the left next to the left collection device 16 of the right outer frame section 22 is likewise pushed to the right when the harvesting header 10 is brought into the transport position . it is supported on the right outer frame section 22 and is thus pivoted both upwards and inwards . this motion between the operating and transport positions and vice versa is illustrated schematically in fig2 with reference to which , it can also be seen that the separating points 34 and 40 do not affect the width of the harvesting header 10 in the transport position . in the top region of fig2 receivers for the separating points are shown schematically , i . e ., holder elements arranged in its rear region . one can see that the divided receivers of the separating points 34 and 40 also do not project over the width of the center frame section 24 . each separating point 34 and 40 can each be moved by a corresponding hydraulic cylinder 42 , which is illustrated in fig3 . the hydraulic cylinder 42 is hinged at its rear end to a console 44 , which is attached for the separating point 34 to the center frame section 24 and for the separating point 40 to the outer frame section 22 . the hydraulic cylinder 42 is hinged at its front end in the direction of travel by means of a fork 48 to a pivot arm 46 , which is connected rigidly to a rod 50 . the rod 50 extends approximately vertically and is supported on a plate 52 so that it can rotate about its longitudinal axis . the plate 52 is connected for the separating point 34 to the center frame section 24 and for the separating point 40 to the outer frame section 22 . at its lower end , the rod 50 is connected rigidly to a pivot arm 54 , which is coupled on its other end by means of a connecting bar 58 to a bearing block 56 , which is attached to the separating point 34 or 40 . the bearing block 56 is supported on the plate 52 so that it can move in the lateral direction . the separating point 34 or 40 is hinged on the bearing block 56 so that it can pivot about a horizontal axis 60 extending perpendicular to the direction of travel , so that the separating point is lifted while traveling over uneven ground . the bearing block 56 is attached to a skid 62 , which is located on the bottom side of the harvesting header 10 and on which the header is supported during harvesting work . if the rear chamber of the double - acting hydraulic cylinder 42 on the connection 64 is charged , the separating points 34 and 40 are pushed to the left into the operation position . if the front chamber of the hydraulic cylinder 42 is charged , the separating points 34 and 40 are pushed to the right into the transport position . in this way , the hydraulic cylinder 42 rotates to its rear end in the console 44 . a latch 68 is connected to this end of the hydraulic cylinder 42 , which also turns when the separating points 34 and 40 are moved between the operating and transport positions . in the operating position , the latch 68 of the hydraulic cylinder 42 of the separating point 40 catches behind a corresponding locking element on the center frame section 24 and the latch 68 of the hydraulic cylinder 42 of the separating point 34 catches behind a corresponding locking element on the left frame section 22 . in this way , an automatic locking of the outer frame sections 22 to the center frame section 22 is achieved in the operating position without additional active elements . a metal sheet panel 70 to the left next to the rear side of the separating point 34 and 40 is used for protecting a top feed auger of the collection device 12 , 14 and 16 . to bring the harvesting header 10 out of the operating position into the transport position , first the hydraulic cylinder 42 is charged to move the separating points 34 and 40 to the right relative to the direction of travel and to release the latches 68 . as soon as suitable sensors output signals that the hydraulic cylinder 42 has brought the separating points 34 and 40 into the transport position , the pivot cylinder 28 is activated to pivot the outer frame sections 22 upwards and inwards . the motion of the harvesting header 10 into the operating position is performed in the reverse sequence , wherein suitable sensors detect when the operating position of the outer frame sections 22 has been reached and then trigger the activation of the hydraulic cylinder 42 , which brings the separating points into their operating position and the latches 68 lock at the locking elements .
a harvesting header comprising a center frame section and two outer frame sections . the outer frame sections can pivot relative to the center frame section between an operating position and a transport position . the center frame section and the outer frame sections carry collection devices for gathering crops and there is a separating point that moves automatically between an operating position and a transport position in the pivot region between the center frame section and the outer frame sections . the separating points arranged in the pivot region between the center frame section and the outer frame sections move between the operating position and the transport position in the horizontal direction perpendicular to the direction of travel and / or to pivot about the height axis .
