摘要

Constructive disposition applied, and rotary cutter roller with double roller and adjusting angle of this utility model refers to a constructive disposition introduced in the crusher and rotary cutter roller (100), which comprises a chassis (200), and a chass previous Is later (300), United States as the pivoting between them by a joint mobile (400).As the angle of attack between the chassis (200, 300) is adjustable by means of a connecting rod (500) arranged at the end opposite the movable board (400). Each of the chassis (200, 300) has a coil (205, 305) with the central axis (210, 310) parallel to the top side of chassis (200, 300) and mancalizado chassis (200, 300) in bearings (220, 320) appropriate.Each of the rollers (205, 305) has distributed along its outer garment various crowns (230, 330) knives bites (235, 335), in which said crowns of knives (230, 330) bites are parallel to each other and arranged at right angles to the longitudinal axis of each roll (205, 305).Each one of the knives bites (235, 335) is? ADA on its two sides and arranged at right angles to the longitudinal axis of the roller (200, 300), resembling a fin. Each roll (205, 305) has a relation between the outer diameter (OD) and length (c) ranged between 0.22 and 0.27, preferably 0.25.Each roll (205, 305) is equipped with a number of knives bites (235, 335) that is between 120 and 170 knives bites (235, 335) for each meter of its length (c), preferably 150 knives bites (235, 335) per meter of length (c).Each chassis (200, 300) has in each of its major side, a comb (250, 350), whose teeth of comb (255, 355) are so arranged as to be contrary to the interim knives bites (235, 335).
