Zusammenfassung:The invention relates to agricultural engineering, namely to the design of cutters of the coarse-stalked crop harvesters and can be used in designing new and upgrading existing harvesters.The coarse-stalked crop harvester contains a frame (1), on which are mounted at least one divider (2), located between two cutters, connected to a drive mechanism (3) with a horizontal shaft (14), a bevel gear (15) and a cylindrical double-reduction gear (16). The harvester also contains a receiving chamber (9), stalk extractors (8) and guide rods (7). Each cutter is a multi-tiered sprocket (4) and a disk (5) with cutting segments (6) on the lower tier. The sprocket (4) and the disk (5) with cutting segments (6) are fixed coaxially on an axle, so that by means of the gearbox (16) the angular rotational velocity of the disk (5) with cutting segments (6) is higher than the rotational velocity of the sprocket (4). On the back upper part of the teeth of the lower tier of the sprocket (4) are made bevels at an angle of 30...45° relative to the upper surface of the tooth of the sprocket (4). On the upper surfaces of the cutting segments (6) are made depressions in the form of helical grooves.The result consists in the rapid removal of cut stalks from the cutting segments of the disk and improvement of the plant harvesting quality. Invenţia se referă la construcţia maşinilor agricole, şi anume la construcţia aparatelor tăietoare ale secerătoarelor pentru recoltarea culturilor cu tulpini groase şi poate fi utilizată la proiectarea secerătoarelor noi şi modernizarea celor existente.Secerătoarea pentru recoltarea culturilor cu tulpini groase conţine un cadru (1), pe care sunt montaţi cel puţin un divizor (2), amplasat între două aparate tăietoare, unite cu un mecanism de acţionare (3) cu un arbore orizontal (14), o transmisie conică (15) şi un reductor cilindric cu două trepte (16). Secerătoarea mai conţine o cameră de recepţie (9), extractoare (8) ale tulpinilor şi tije de ghidare (7). Fiecare aparat tăietor reprezintă un tambur dinţat (4) cu mai multe nivele şi un disc (5) cu segmente tăietoare (6) la nivelul inferior. Tamburul dinţat (4) şi discul (5) cu segmentele tăietoare (6) sunt montate coaxial pe un ax, astfel încât prin intermediul reductorului (16) viteza unghiulară de rotaţie a discului (5) cu segmentele tăietoare (6) este mai mare decât viteza de rotaţie a tamburului dinţat (4). Pe partea superior-posterioară a dinţilor nivelului inferior al tamburului (4) sunt executa
