Title
(EN) AN IMPROVED CHOPPER
(FR) MACHINE A HACHER AMELIOREE
Abstract
(EN) In a straw chopper (2) comprising a rotor (7) with knives mounted thereon, and counter-knives (10) interacting with the rotor-mounted knives (9) and being adjustable as to their position in order to diminish or increase, according to wish, the through-flow and degree of communition of various types of material (5) to be chopped, upper and lower guides (11, 12) are provided ahead of and after the counter-knives (10), as seen in the direction (B) of rotation of the rotor-mounted knives (9), said guides being adjustable as to their position with respect to the chopper rotor and having the same extension as the chopper rotor (7), which guides are formed with guide edges (14, 15) which are directed towards the outer free ends (13) of the rotor-mounted knives (9) in order to force the material (5) to be chopped into the chopper rotor (7). The distances (C and D, respectively) between the respective guide edges (14, 15) and the free ends (13) are variable and are made to increase upon adjustment of the position of the counter-knives (10) from a position (I) for maximum chopping to a position for minimum chopping.
(FR) Machine à hacher la paille (2) comprenant un rotor (7) sur lequel sont montées des lames, ainsi que des contre-lames (10) fonctionnant réciproquement avec des lames (9) montées sur le rotor et dont la position peut se régler, afin de diminuer ou d'augmenter, selon le cas, le débit et le degré de broyage des différents types de matières (5) à hacher; des guides supérieur et inférieur (11, 12) se trouvant en avant et en arrière des contre-lames (10), vus dans le sens (B) de rotation des lames (9) montées sur le rotor, la position desdits guides étant réglable par rapport au rotor de la machine à hacher et possédant le même prolongement que ledit rotor (7); lesdits guides comportent des bords de guidage (14, 15) dirigés vers les extrémités libres extérieures (13) des lames (9) montées sur le rotor, afin de pousser la matière (5) à hacher dans le rotor (7). Les distances (C et D respectivement) entre les bords de guidage respectifs (14, 15) et les extrémités libres (13) sont variables et peuvent s'agrandir par réglage de la position des contre-lames (10) d'une position (I) de broyage maximum à une position de broyage minimum.
