Abstract: A sugar-cane harvester having a tubular frame is provided. The frame is configured for mounting a set of sugar-cane harvesting devices (2, 3, 4, 5, 6, 7, 8, 9,10), and is formed by a set of tubular parts linked mechanically to one another. The mechanical linking between the tubular parts that form the frame are made via at least one of rivets, soldering, or flanges. The frame may also be an exoskeleton-type frame configured for receiving all the components that form the industrial system of a sugar-cane harvester.

Abstract: One describes a rotor (1) for an exhaust-fan assembly (4) of an 5 agricultural machine, the rotor (1) comprising a central shaft (7), a first portion (31) provided with an inlet deflector (15) having a substantially elliptical profile, defining a tapered inlet end (26). The rotor, which is also provided with a set of blades (13), further comprises a second portion (29) provided with an outlet deflector (22) having a substantially elliptical profile, so that the 10 first and the second portions (31, 29) are associated to the central shaft (7). According to the invention, one provides a rotor that promotes efficient cleaning of harvested cane.

Abstract: One describes a feed-belt (100) for a sugar-cane harvester, comprising first (1) and second (2) belts that substantially overlap each other and define a space for passage of cut cane between them (1, 2), the first and the second belts (1,2) exhibiting a substantially curved profile. The invention has the objective of providing a feed-belt (100) for a sugar-cane harvester that can be used for the processes of both harvesting cane for grinding and harvesting seedlings for plantation, also providing a decrease in the total weight of the machine, lower hydraulic power required for the feed assembly, a smaller number of hydraulic components and lower final cost of the machine, besides simplicity and lower maintenance cost.

Abstract: 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).

Abstract: 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.

Abstract: The present invention relates to a turn system actuated by hydraulic cylinders, applied to the four wheels of sugar-cane harvesters, wherein the harvester (80) comprises a rear axle (23) and a front axle (24), with wheel assemblies (9) associated to the axles (23, 24), wherein the rear axle (23) and the front axle (24) have a turn system, the one of the rear axle (23) being actuated by means of a double-action rear hydraulic cylinder (1) and that of the front axle (24) being actuated by means of a double-action front hydraulic cylinder (11), the hydraulic cylinders (1, 11) receiving a flow of oil through at least one flow divider (61) connected to an ortibrol (65) actuated by means of a steering wheel (60) of the harvester (80), the flow of oil received by the flow divider (61) being proportional to a factor related to the turn of the steering wheel (60), the turn system enabling the turn of the wheel assemblies (9) in amplitude ranging from 0.
