Patent number: 9976567Abstract: The present invention relates to a rotor (90) applied to an extractor-fan assembly (80) for agricultural machines, especially for sugar-cane harvesters, the rotor (90) comprising a set of blades (1) fixed to a hub (2). Each of the blades (1) has such a construction that defines a root angle (3) that may range from 47 to 59 degrees, a medium angle (4) that may range from 53 to 69 degrees and a trailing angle (5) that may range from 66 to 78 degrees. Due to the construction angles of the blades (1), the air flow comes in contact with the rotor (9) smoothly, without any turbulence in its displacement, which results in high efficiency and efficacy of the extractor-fan assembly (80).Type: GrantFiled: December 10, 2014Date of Patent: May 22, 2018Assignee: MARCHESAN IMPLEMENTOS E MAQUINAS AGRICOLAS TATU S.A.Inventors: Dacio Helene Junior, Valter Palmute

Patent number: 9801336Abstract: Provided is a floating base-cutter assembly (16) for use on sugar-cane harvesters, the assembly being formed by two base-cutters. Each of the base-cutters (16) comprises a set of cutting knives (9). The base-cutter assembly (16) comprises an adjustable set of cutting knives (9) that may be selectively adjustable with respect to the ground. The base-cutter assembly (16) is also mounted on the harvester body via a set of articulated rods (2, 5). The base-cutter assembly (16) also includes an electric switch (7) and an inverted-shell-shaped component (8) that collectively control a hydraulic or pneumatic cylinder (4) to articulate the rods (2,5) and maintain the set of cutting knives (9) at a redetermined distance relative to the ground surface, regardless of variations in the ground surface.Type: GrantFiled: January 7, 2015Date of Patent: October 31, 2017Assignee: Marchesan Implementos e Maquinas Agricolas Tatu S.A.Inventor: Valter Palmute

Patent number: 9545056Abstract: The objective of the present invention is achieved by means of a row divider (1) applied to a sugar cane harvester (100). Said device (1) comprises at least one helicoidal lift (2) connected to an engine. Said helicoidal lift (2) has a conical shape geometry of variable cross section around an imaginary central axis (102), and comprises a first segment (3) and a second segment (4). The first segment (3) establishes a first generatrix (5) which defines an angle a to the central axis (102) and comprises a first screw thread (6) in its outer surface. The second segment (4) establishes a second generatrix (7) which defines an angle ? to the central axis (102), so that ? has a greater value than a. Said second segment (4) comprises a second screw thread (8) in its surface, which is oriented in the opposite direction of the first screw thread (6).Type: GrantFiled: March 18, 2014Date of Patent: January 17, 2017Assignee: Marchesan Implementos e Máquinas Agrícolas Tatú S.A.Inventor: Valter Palmute
