Multi-row single grain sowing machine and method for adjusting this multi-row single grain sowing machine

摘要

Multi-row single grain sowing machine with a frame, which at least one arranged transversely to the driving direction, it can be telescoped in its width changeable frame element, and with a plurality of working elements arranged on this frame element which, for the purpose of adjustment of the mutual distance during the telescoping, copying operation of the frame element, taking along of the frame element are displaceable by means of suitable first contour, with the adjustment of the mutual distances between the working elements to one another by means of presetting at least one distance holder device is carried out in discrete steps. In order to have a plurality of rows, as well as the present invention to provide a method which a comfortable and safe and time effective adjustment of the distances between the working elements of the single grain sowing machine makes it possible to one another, it is provided that the presetting of the at least one distance holder device independently of the actual width of the telescopic frame member and / or the current distance between the working elements can be carried out with one another by the fact that, on the frame element at least one latch rail is arranged, wherein a first contour in a locking element, which is representative of the distances between the working elements corresponding locking position of the latch rail engages that, within the latch rail the first stop element and a second stop element is associated with a working element are movable relative to each other, and the first and second stop element are suitable for that, in the case of telescoping of the frame element in a first direction the second stop element the first stop element, with release of the stop action makes and that, in the case of a telescoping in a second direction the first stop element, while maintaining the stop action against the second stop element is running, whereby the first stop element moves the second stop element and which, in this context, which is connected with the second stop element into the working element, the preset distances between the working elements corresponding position along with it.
