摘要

protection for the cutting knife set of an agricultural implement and agricultural implement for cutting and harvesting grain. The present invention relates to a new protection for the cutting knife set of an agricultural implement applied, for example, to a harvester or grain harvester, which has been designed to allow adjustment of the space formed between the knives and the thus obtaining a simplified adjustment of the shear effect for cutting the stems and stalks of plants. more particularly, said protection is basically comprised of lower (18a) and upper (18b) protectors secured to one another by a securing member (19) so as to press a movable shim (20) configured with an inclined surface ( 20a) for contacting the inner surface (21) of one of said guards (18a, 18b), wherein the displacement of said movable shim (20) is controlled by a limiter (22) disposed on the side to which it is located. said movable shim (20) tends to move with the pressure of said fastener (19).
