SYSTEM AND METHOD FOR EXTRACTING BUDS FROM A STALK OF A GRAMINACEOUS PLANT

摘要

The present invention is related to a system for extracting buds (8) from a stalk (1) of a graminaceous plant. The system comprises a main detection device (11) for detecting a bud on a stalk; a conveyer (2) for conveying the stalk to the main detection device; and a main cutting device (17) for cutting out a vegetal tissue comprising the bud based on the detected position of the bud; wherein said conveyer comprises pressure roller units (3) arranged at adjacent positions along the longitudinal extension of the stalk for exerting radial forces to the stalk, said pressure roller units are coupled to a control unit (4) for controlling the radial forces exerted by the pressure roller units to said stalk independently of one another so that the stalk is urged in a straight line. Furthermore, the invention relates to a corresponding method that may be carried out by this system.
