Two-row sugarcane harvester

Description

1 / 33 Two-row sugarcane harvester - field of application

[0001] This descriptive report concerns a patent for invention relating to constructive arrangements introduced in a sugarcane harvester for cutting two rows / lines, which aims to meet the demand for high-performance and efficient agricultural equipment. FUNDAMENTALS OF THE INVENTION

[0002] The first major technological revolution in the bioenergy sector was the introduction of raw sugarcane harvesters, a movement that began in the 1990s and culminated in the end of manual sugarcane cutting in mechanizable areas.

[0003] In addition to higher operational efficiency, the elimination of burning and the start of mechanization reduced the environmental impact of the operation, while also improving working conditions for employees.

[0004] After years of learning and adaptation, the system is consolidated, and the sugarcane harvest grows annually.

[0005] The 2022 / 2023 harvest closed with 610 million tons, and the expectation is that the 2023 / 2024 harvest will end at 637 million, according to the National Supply Company (Conab).

[0006] The world is searching for alternatives to fossil fuels, which puts ethanol and biomass in the spotlight; some researchers are already working with the hypothesis that sugarcane may be even more efficient than photovoltaic panels in generating sustainable energy. Petition 870250014437, dated 21 / 02 / 2025, page 10 / 73 2 / 33

[0007] With the introduction of mechanized harvesting on a larger scale due to demand, the sugarcane and energy sector faced new challenges, such as the longevity of the sugarcane field, the impurity content, specialized labor, logistics and operating costs, which led assemblers, bioenergy units and suppliers to prepare for what can be considered the second major technological leap in the sector; the transition from mechanized harvesting of raw sugarcane from one to two rows.

[0008] By harvesting two rows simultaneously, productivity is almost doubled, and fuel consumption is reduced by 30%; the need for transshipment tractors by 28%; losses due to splintering are reduced by 50% (around three tons / hectare); and the compacted area due to the track width of these machines is reduced by 50%, as they run exactly in the center of the inter-row spaces, always skipping a row or traffic lane; a fact that benefits the sprouting and development of the ratoons, positively impacting the productivity and longevity of the sugarcane fields.

[0009] With all these benefits, mechanized harvesting generates a cost reduction of approximately 22% per ton. SUMMARY OF THE INVENTION

[0010] In response to this evolution, the present sugarcane harvester for cutting two rows / streets is proposed, which is based on the sugarcane harvester described in patent document BR102023009112-1, of the applicant, incorporated herein by reference, which, by restructuring a used single-row machine available on the market, now incorporates two platforms, in addition to other improvements, Petition 870250014437, dated 21 / 02 / 2025, p. 11 / 73 3 / 33 passing through harvesting two rows of sugarcane simultaneously, as described below.

[0011] The sugarcane harvester for cutting two rows / streets of the present invention incorporates improvements in its chopper modules, its chassis being modified to smooth the entry of the cane into the machine, having gearboxes of the chopper modules that allow the replacement of the rollers without having to disassemble its cover, also allowing the synchronization of these, through a synchronizing support, without having to open it.

[0012] The sugarcane harvester for cutting two rows / streets of the present invention also has a base chassis equipped with appropriate supports to receive the other sub-assemblies, allowing the machine to be assembled in a modular way, without the need for cutting and welding to replace the sub-assemblies, only by loosening screws, washers and nuts.

[0013] The sugarcane harvester for cutting two rows / streets of the present invention has a larger, straight primary elevator, which increases the equipment's productive capacity, allowing it to harvest more robust sugarcane at a higher speed. This elevator can be built in two configurations: one with a rubber conveyor belt joined by vulcanized rollers, and the other with a conveyor chain and cleats, joined by shafts driven by gears. The primary elevator is fixed by a cylinder and bearing, allowing for downward movement with the machine stopped and switched off, along with two side covers that move with the elevator, for Petition 870250014437, dated 21 / 02 / 2025, p. 12 / 73 4 / 33 retraction of the same, freeing up space for maintenance inside the machine.

[0014] The sugarcane harvester for cutting two rows / streets of the present invention has a modular primary extractor, fixed by screws, washers and nuts to the base chassis, with a larger internal dimension, for better cleaning of impurities from the two rows, ensuring better efficiency with lower rotations, generating fuel savings, with oil inside the tube, eliminating the need for periodic lubrication, providing a longer service life to the assembly, also having as a differential the fact that only the primary hood rotates, by means of a cylinder disposed on a nylon ring, which avoids friction and wear, said primary hood being constructed of metallic material joined by welding or polymeric.

The shaft also has O-ring seals that prevent impurities from entering the bearings and causing wear. The slewing table is constructed of welded metal and fixed to the slewing base shaft by a set of screws, washers, and nuts. The secondary elevator can rotate 180° via two hydraulically connected cylinders arranged in an inverted T-shape, so that when one cylinder closes, the other opens in the same direction as the rotation. The secondary elevator is fixed above this assembly by a set of screws, washers, and nuts.This machine transports sugarcane from the primary elevator outlet to the transshipment point via conveyor chains and cleats. Built with a wider width to accommodate two-row harvesting, it is divided into three modules, facilitating replacement and consequently reducing costs. The fixed module on the rotary table allows for radial rotation around its axis, with the lifting movement performed by the second module. The primary elevator outlet can be closed off in the primary extractor, ensuring better exhaust and eliminating billet loss in that area, as occurs in other machines on the market. Two covers are also included to facilitate access to the machine's interior for maintenance, while also allowing the operator to move the elevator.

[0031] The platforms (2) of the sugarcane harvester (1) for cutting two rows / streets now proposed employ the same construction as patent BR102023009112-1, and also aim to direct, perform basal cutting, transport and chop the sugarcane in front of the machine, with modification only in the arrangement of the right and left chopper modules (3), which have had their angles of attack altered, changing from 18° to 5°, thus smoothing the entry of the cane into the machine, generating an increase in harvesting speed, which is further aided by the widening of the primary elevator that Petition 870250014437, dated 21 / 02 / 2025, p. 25 / 73 17 / 33 transports the logs dropped by the chippers, which increased from 875 mm to 1200 mm.

[0032] The chopper boxes (4) of the sugarcane harvester (1) for cutting two rows / streets now proposed, allow synchronization of the rollers where the knives that chop the cane into stalks of 15 cm to 20 cm are installed, are constructed of sheet metal joined by welding, or cast in shape, with housings for seals, since they contain 6.5 L of oil inside for lubrication of moving components such as, for example, bearings, gears and others, and whose shapes improve the efficiency of lubrication of these, and eliminate the need to open them for replacement of the chopper rollers, as well as for their synchronization, which can be done through the openings provided on the outside of said boxes, by means of a synchronizing support (5), fixed to the upper shaft of the chopper box, and, after positioning, loosening the front screws (6), and moving the hexagon (7) of the template (8), in order to close or open said template, according with the need, and,After adjustment, the front screws were tightened, and the synchronizer support was removed. The chipper housings also have magnetic plugs (9) on the top and bottom, for removing iron filings, to increase the service life of bearings, seals and others, as well as an easily visible oil level indicator (10), and a breather (11).

[0033] The base chassis (12) of the sugarcane harvester (1) for cutting two rows / streets now proposed is constructed of metallic material joined by welding and fixing bolts, has supports designed to receive all other machine components, and was developed in such a way as to Petition 870250014437, dated 21 / 02 / 2025, page 26 / 73 18 / 33 withstands all the stresses resulting from harvesting, preventing cracks and twists, its main differentiating factor being the modular way in which its subcomponents are assembled, which are fixed by means of screws and wedges, without the need for welding, which provides greater speed in replacements and increases its lifespan, unlike what occurs in current machines where, in the case of maintenance, torches and sanders are used, which generates greater expenditure of time and fragility of the chassis material, due to the modification of its molecular structure, which can generate cracks and reduce its lifespan.

[0034] The primary elevator (13) of the sugarcane harvester (1) for cutting two rows / streets now proposed, which has the function of transporting the stalks thrown by the choppers to the primary extractor, having a straight shape, and which articulates in relation to the base chassis with the aid of cylinders (14) and bearings (15), allowing its front part to be lowered to the ground, providing access to its interior for maintenance; this movement is only possible when the machine is switched off, also having a pin and counterpin to prevent cylinder failure during harvesting, said primary elevator can be constructed in two embodiments, the first being formed by a cleated rubber conveyor belt (16) circumscribing two vulcanized rollers (17), mounted in a trough (18) that eliminates impurities, minerals and vegetables, that fall from the conveyor belt, being suitable for use in harvesting, both of the main crop and of seedlings, as it does not damage the buds of the cane;The second embodiment of the primary elevator consists of a cleated conveyor chain, and differs from the previous one by transporting the sugarcane through; Petition 870250014437, dated 21 / 02 / 2025, page 27 / 73 19 / 33 fixed slats (19) on chains (20) that are rotated by gears (21) fixed to shafts (22). The primary elevator also has side covers (23), which prevent loss of cane thrown by the choppers, which, when the primary elevator is lowered, are retracted inside by hydraulic cylinders (24), freeing up access space.

[0035] The primary extractor (25) of the sugarcane harvester (1) for cutting two rows / streets now proposed, which has the function of removing harvested mineral and vegetable impurities, is composed of a structure (26) constructed of metallic material and joined by welding, which supports all the other components of the primary extractor, and through which it is joined to the base chassis, constituting a modular system, which can be replaced simply by loosening the fastening items, unlike those existing on the market which are fixed by welding, also provided lower (27) and upper (28) wear plates, constructed of noble metallic material, which protect the structure from wear caused by impurities during exhaustion, due to friction at high speed, the lower wear plate being formed by a split ring that has eight internal fins with a curved profile and arranged at 40° angles, to guarantee tangential airflow, for better cleaning,wherein the upper wear plate is formed by a smooth split ring placed above the lower wear plate, a nylon ring (29) is also provided, which is a lubricating material with a low coefficient of friction, which is fixed to the structure by a set of screws, washers and nuts, for easy replacement if necessary, also facilitating the rotation of the hood (30), avoiding friction and wear of the assembly, the hood being constructed of material, Petition 870250014437, dated 21 / 02 / 2025, p. 28 / 73 20 / 33 metallic or polymeric, whose function is to remove impurities that are sucked in by the fan (31) and deposited between the rows of sugarcane. Its rotation, of only 30°, to the right or left, is synchronized with the secondary elevator, which will be described in more detail later. It differs from those on the market by rotating, through the cylinder (32), only the hood and not the entire primary extractor assembly. The fan, made of metallic material joined by welding, operates at high speeds. Its propellers, made of noble material with equal mass for better balance, and with a profile that provides greater exhaust efficiency, are fixed by screws, washers, and nuts for easy replacement. It has a spinner (33), made of polymeric material, located below the fan, which directs the impurities to the tip of the propellers, where the speed is higher, for greater cleaning efficiency.whose fixation is made by support (34), with left-hand thread, so as not to loosen with the counter-clockwise rotation of the fan, also having a fan support hub (35) in the center of the primary extractor, differing from usual ones by providing oil inside the tube (36) of the fan rotation shaft, with seals, so that the bearings are immersed in oil, making periodic lubrication unnecessary, increasing the service life of the whole assembly, and whose fixation is made by screws, washers and nuts, also having an oil level indicator, in addition to side supports, breather and auxiliary lights for use at night.

[0036] The pivot base (35) of the sugarcane harvester (1) for cutting two rows / streets as proposed herein, fits into the base chassis, fixed by a set of screws, washers and Petition 870250014437, dated 21 / 02 / 2025, p. 29 / 73 21 / 33 nuts, and, through the turning table (36), which functions as a support for the turning of the first module of the secondary elevator (37), defined modular assembly, which can be replaced individually by releasing the fastening items, unlike those on the market, which are fixed by welding; said turning base having an axis (38) in noble material, where said turning table is fixed, by means of a set of screws and washers, and whose turning is obtained by bearings, equipped with seals, which facilitate turning as well as prevent the entry of dirt, increasing the durability of the assembly, unlike market models, which employ sets of pins and bushings, also having cylinders (39), responsible for the turning of the secondary elevator, which act with cross interconnection, so that when one closes the other opens, and vice versa, at a maximum angle of 180°, limited by PLASTIPRENE® stops, which is capable of supporting up to 10.000 kgf, fixed by supports, screws and washers, being easily replaceable if necessary. The turntable is constructed of metal material joined by welding, being fixed to the first module of the secondary elevator, through upper fixing supports (40), and to the turntable base, through lower supports (41), both by means of a set of screws, washers and nuts.

[0037] The secondary elevator (37) of the sugarcane harvester (1) for cutting two rows / streets now proposed, which efficiently transports two rows of sugarcane in billet form launched by the primary elevator to the transshipment, having its width increased by approximately 200 mm compared to conventional market elevators, in order to increase its load capacity, and is also the first elevator developed with a two-point articulation system, which Petition 870250014437, dated 21 / 02 / 2025, p. 30 / 73 The 22 / 33 allows operation in several different positions, according to the operator's needs, and also facilitates maintenance, as the assembly can be positioned parallel to the ground when fully lowered.
