Description

“PLATAFORMA DE MANUTENÇÃO PARA UMA MÁQUINA AGRÍCOLA E MÁQUINA COLHEDORA DE PLANTAS ALTAS E CAULEOSAS” “MAINTENANCE PLATFORM FOR AN AGRICULTURAL MACHINE AND HARVESTING MACHINE FOR HIGH AND STONEY PLANTS”

Campo de Invenção Field of Invention

[0001] A presente invenção refere-se, de um modo geral, a uma nova plataforma de manutenção particularmente desenvolvida para ser utilizada em máquinas agrícolas, tais como aquelas destinadas à colheita de plantas altas e cauleosas, como é o caso da cana-de-açúcar e sorgo-doce. Ainda, a presente invenção se refere a uma nova máquina de colher plantas altas e cauleosas a qual incorpora a plataforma de manutenção de modo a permitir a locomoção do operador e, ainda, melhorar as condições de limpeza no topo da máquina. [0001] The present invention relates, in general, to a new maintenance platform particularly developed for use in agricultural machines, such as those intended for the harvest of tall and stem plants, as is the case of sugarcane -sugar and sweet sorghum. In addition, the present invention relates to a new machine for harvesting tall and stem plants which incorporates the maintenance platform in order to allow the operator to move around and also improve the cleaning conditions at the top of the machine.

Fundamentos da Invenção Fundamentals of the Invention

[0002] De acordo com o estado da técnica, existem inúmeros modelos de máquinas e equipamentos agrícolas destinados a promover o aumento da produtividade nas colheitas dos diversos tipos de culturas vegetais, por exemplo, as colheitadeiras de grãos, as forrageiras e, também, as máquinas colhedoras das chamadas plantas altas e cauleosas, como é o caso da cana e do sorgo. [0003] Essas máquinas colhedoras de plantas altas e cauleosas são projetadas e desenvolvidas para propiciar a colheita deste tipo específico de cultura, uma vez que, suas características intrínsecas exigem condições particulares para o seu adequado processamento, desde o corte das plantas até a transferência para os transbordos e/ou carretas. [0002] According to the state of the art, there are numerous models of agricultural machinery and equipment designed to promote increased productivity in the harvests of different types of vegetable crops, for example, grain harvesters, forages and also harvesting machines of the so-called tall and stem plants, such as cane and sorghum. [0003] These harvesting machines for tall and stem plants are designed and developed to provide the harvest of this specific type of crop, since their intrinsic characteristics require particular conditions for their adequate processing, from cutting the plants to transferring them to transhipments and / or trailers.

[0004] Basicamente, como deve ser apreciado pelos técnicos no assunto, esse modelo de máquina destinada à colheita e processamento de plantas altas e cauleosas compreende uma estrutura relativamente alta, onde em seu topo são instalados alguns dos componentes da máquina, por exemplo, os trocadores de calor dos sistemas de arrefecimento, motores, bombas, etc., os quais exigem manutenções periódicas fazendo com que o operador suba e se desloque no topo da máquina para, então, realizar as devidas tarefas. [0005] Dessa forma, conforme deve ser de conhecimento dos técnicos no assunto, o espaço para se movimentar no topo dessas máquinas é relativamente restrito, o que acaba dificultando até mesmo as tarefas mais simples de manutenções, além de colocar em risco a integridade dos operadores. [0004] Basically, as it should be appreciated by the technicians in the subject, this model of machine intended for the harvest and processing of tall and stem plants comprises a relatively high structure, where on its top some of the machine's components are installed, for example, the heat exchangers for cooling systems, motors, pumps, etc., which require periodic maintenance, causing the operator to climb and move on the top of the machine to perform the necessary tasks. [0005] Thus, as the technicians in the subject should know, the space to move on top of these machines is relatively restricted, which ends up making even the simplest maintenance tasks difficult, in addition to jeopardizing the integrity of the machines. operators.

[0006] Assim, no intuito de aumentar o espaço disponível para que os operadores se movimentem no topo das máquinas, foram desenvolvidos alguns modelos de plataformas de manutenção que são usualmente instaladas nas proximidades dos trocadores de calor dos sistemas de arrefecimento da dita máquina, e são fixadas de modo que o seu assoalho fique no mesmo plano do topo da máquina para, com isso, aumentar o espaço para que o operador se movimente e realize as manutenções necessárias com mais facilidade e segurança. [0006] Thus, in order to increase the space available for operators to move on top of the machines, some models of maintenance platforms have been developed that are usually installed in the vicinity of the heat exchangers of the cooling systems of said machine, and they are fixed so that their floor is on the same plane as the top of the machine, thereby increasing the space for the operator to move around and carry out the necessary maintenance with greater ease and safety.

[0007] No entanto, apesar de funcionais, essas plataformas revelam alguns inconvenientes gerados em razão de sua configuração e construção, que propicia o acúmulo de palha no topo das máquinas durante a operação, afetando e comprometendo o funcionamento de diversos componentes e mecanismos essenciais para o funcionamento da máquina. Particularmente, a título meramente exemplificativo, a palha acumulada no topo da máquina pode eventualmente obstruir as passagens de ar dos trocadores de calor dos sistemas de arrefecimento, afetando o funcionamento desses sistemas e, consequentemente, da máquina como um todo. Esse tipo de problema pode aumentar a necessidade de interrupções nos trabalhos e paradas da máquina para desobstruir essas passagens de ar ou, até mesmo, executar eventuais consertos em casos que ocorra algum dano nesse sistema, ou em qualquer outro componente, provocado por esse acúmulo de palha na região de topo da máquina. [0007] However, although functional, these platforms reveal some inconveniences generated due to their configuration and construction, which allows the accumulation of straw on the top of the machines during operation, affecting and compromising the functioning of several components and mechanisms essential for the operation of the machine. Particularly, by way of example only, the straw accumulated on the top of the machine can eventually block the air passages of the heat exchangers of the cooling systems, affecting the functioning of these systems and, consequently, of the machine as a whole. This type of problem can increase the need for interruptions in the work and stops of the machine to unblock these air passages or even carry out eventual repairs in case of damage to this system, or any other component, caused by this accumulation of air. straw at the top of the machine.

[0008] Em síntese, nota-se que o estado da técnica carece de soluções e alternativas para a construção das plataformas de manutenção de máquinas agrícolas capazes de obter uma área segura para os trabalhos dos operadores e condutores, mas principalmente impedir o acumulo de palha no topo da máquina, evitando, com isso, riscos de danificar eventuais sistemas e mecanismos que se encontram instados nesta região da máquina, como por exemplo, os trocadores de calor dos sistemas de arrefecimento, bombas, motores, etc. Como deve ser apreciado pelos técnicos no assunto, os modelos de plataformas conhecidos atualmente no estado da técnica não conseguem evitar o acúmulo de palha na região de topo da máquina, bem como o comprometimento das passagens de ar, comprometendo a produtividade das colheitas em virtude das paralizações da máquina para limpeza. [0008] In summary, it is noted that the state of the art lacks solutions and alternatives for the construction of machine maintenance platforms able to obtain a safe area for the work of operators and drivers, but mainly to prevent the accumulation of straw on the top of the machine, thus avoiding the risk of damaging any systems and mechanisms that are installed in this region of the machine, such as example, heat exchangers for cooling systems, pumps, motors, etc. As should be appreciated by the technicians in the subject, the platform models known today in the state of the art cannot prevent the accumulation of straw in the top region of the machine, as well as the compromise of the air passages, compromising the productivity of the harvests due to the machine shutdowns for cleaning.

[0009] Dessa forma, apesar de se mostrarem funcionais até os dias de hoje, verificou-se que as plataformas para manutenções de máquinas agrícolas conhecidas e disponíveis no estado da técnica carecem de uma solução prática e funcional que proporcione uma área segura para que os operadores e condutores possam executar os processos de manutenção, mas principalmente consiga eliminar, ou minimamente reduzis, o acumulo de palha no topo dessas maquinas para, desse modo, reduzir a necessidade de paradas para limpeza do topo dessas máquinas. Assim, é importante frisar que são esses, dentre outros, os objetivos e soluções que se pretende obter com o desenvolvimento da presente invenção. [0009] Thus, despite being functional to this day, it was found that platforms for maintenance of agricultural machinery known and available in the state of the art lack a practical and functional solution that provides a safe area for operators and drivers can carry out the maintenance processes, but mainly manage to eliminate, or minimally reduce, the accumulation of straw on the top of these machines, thereby reducing the need for stops to clean the top of these machines. Thus, it is important to emphasize that these are, among others, the objectives and solutions that are intended to be obtained with the development of the present invention.

The reference numbers used are repeated throughout the figures to identify identical or similar parts. The terms eventually used such as "above", "below", "front", "back", "right", "left" etc. and their variants should be interpreted according to the guidance given in Figure 1.

[0024] Os termos aqui empregados como colheitadeira, colhedora, máquina de colher e suas variantes são utilizados indistintamente para indicar uma máquina agrícola destinada à colheita de uma cultura vegetal e, no caso desta descrição, à colheita de plantas altas e cauleosas, tal como a cana-de- açúcar, a cana energia, o sorgo etc. [0024] The terms used here as a combine harvester, harvester, harvesting machine and its variants are used interchangeably to indicate an agricultural machine intended for harvesting a vegetable crop and, in the case of this description, for harvesting tall and stem plants, such as sugar cane, energy cane, sorghum etc.

[0025] Com relação agora aos desenhos, a Figura 1 ilustra uma vista lateral de uma realização de uma máquina agrícola 10 de acordo com aspectos conhecidos no estado da técnica. Conforme foi mostrado, a máquina 10 é configurada como uma colheitadeira de cana-de-açúcar. Entretanto, em outras realizações, essa máquina 10 pode corresponder a qualquer modelo de colheitadeira agrícola adequada conhecida do estado da técnica. [0025] With reference now to the drawings, Figure 1 illustrates a side view of an embodiment of an agricultural machine 10 according to aspects known in the prior art. As shown, machine 10 is configured as a sugarcane harvester. However, in other embodiments, this machine 10 can correspond to any suitable agricultural harvester model known in the prior art.

[0026] Ainda com relação à Figura 1 , a máquina 10 inclui um chassi 12, um par de rodas frontais 14, um par de rodas traseiras 16, e uma cabine de operador 18. A máquina 10 pode também incluir uma fonte primária de energia (por exemplo, um motor montado no chassi 12) que energiza um ou ambos pares de rodas 14, 16 por meio de uma transmissão (não mostrada). Alternativamente, a máquina 10 pode ser uma colheitadeira acionada sobre esteiras e, portanto, pode incluir esteiras acionadas pelo mecanismo motor em substituição às rodas ilustradas 14, 16. O mecanismo motor pode também acionar uma bomba de fluido hidráulico (não mostrada) configurada para gerar fluido hidráulico pressurizado para acionar vários componentes hidráulicos da máquina 10, inclusive as rodas ou esteiras. [0027] Adicionalmente, a máquina 10 pode incluir vários componentes para cortar, processar, limpar e descarregar cana-de-açúcar conforme a cana é colhida de um campo agrícola 20. Por exemplo, a máquina 10 pode incluir um conjunto de cortador de pontas 22 posicionado na sua extremidade frontal para interceptar a cana-de-açúcar conforme a máquina 10 se movimenta na direção de avanço, tal como indicado pela seta “X” na Figura 1 . Conforme mostrado, o conjunto de cortador de pontas 22 pode incluir tanto um disco aglutinador 24 quanto um disco cortador 26. O disco aglutinador 24 pode ser configurado para aglutinar caules de cana-de-açúcar, de modo que o disco cortador 26 possa ser usado para cortar a ponta de cada caule. Geralmente, a altura do conjunto cortador de pontas 22 pode ser ajustável por meio de um par de braços 28 hidraulicamente erguidos e baixados, conforme desejado pelo operador. [0026] Still with respect to Figure 1, the machine 10 includes a chassis 12, a pair of front wheels 14, a pair of rear wheels 16, and an operator cabin 18. Machine 10 can also include a primary source of energy (for example, a motor mounted on the chassis 12) that energizes one or both pairs of wheels 14, 16 by means of a transmission (not shown). Alternatively, machine 10 can be a track-driven harvester and therefore can include tracks driven by the motor mechanism in place of the illustrated wheels 14, 16. The motor mechanism can also drive a hydraulic fluid pump (not shown) configured to generate pressurized hydraulic fluid to drive various hydraulic components of the machine 10, including the wheels or tracks. [0027] Additionally, machine 10 may include various components for cutting, processing, cleaning and unloading sugar cane as the cane is harvested from an agricultural field 20. For example, machine 10 may include a set of tip cutters 22 positioned at its front end to intercept the sugarcane as the machine 10 moves in the forward direction, as indicated by the arrow “X” in Figure 1. As shown, the tip cutter assembly 22 can include both a binder disk 24 and a binder disk 26. Binder disk 24 can be configured to bind sugar cane stems so that the cutter disk 26 can be used to cut the tip of each stem. Generally, the height of the tip cutter assembly 22 can be adjustable by means of a pair of arms 28 hydraulically raised and lowered, as desired by the operator.

[0028] Adicionalmente, a colheitadeira 10 pode incluir um divisor de linhas 30 que se estende para cima e para trás a partir do campo 20. Em geral, o divisor de linhas 30 pode incluir dois rolos de alimentação em espiral 32, também conhecidos como “pirulito”. Cada rolo de alimentação 32 pode incluir uma sapata de solo 34, visto que sua extremidade inferior auxilia o divisor de linhas 30 separando os caules de cana-de-açúcar para colheita. Além disso, conforme mostrado na Figura 1 , a colheitadeira 10 pode incluir um rolo tombador 36 posicionado próximo às rodas frontais 14 e um rolo com projeções 38 posicionado atrás do rolo tombador 36. Conforme o rolo tombador 36 é girado, os caules de cana-de-açúcar colhidos são tombados enquanto o divisor de linhas 30 aglutina os caules do campo agrícola 20 no sentido para o interior da máquina 10. Adicionalmente, conforme mostrado na Figura 1 , o rolo com projeções 38 pode incluir uma pluralidade de aletas 40 intermitentemente montadas que auxiliam em forçar os caules de cana-de-açúcar para baixo. Conforme o rolo 38 é girado durante a colheita, os caules de cana-de-açúcar que foram tombados pelo rolo tombador 36 são separados e, posteriormente, tombados pelo rolo 38 conforme a máquina 10 continua a ser movida para frente com relação ao campo 20. [0028] Additionally, the combine 10 can include a line divider 30 that extends up and back from field 20. In general, the line divider 30 can include two spiral feed rollers 32, also known as "lollipop". Each feed roller 32 may include a soil shoe 34, since its lower end aids the divider of lines 30 by separating the sugarcane stems for harvest. In addition, as shown in Figure 1, the combine 10 can include a tipping roller 36 positioned close to the front wheels 14 and a projection roller 38 positioned behind the tipping roller 36. As the tipping roller 36 is rotated, the cane stems are rotated. harvested sugar canes are tipped while the line divider 30 binds the stems of the agricultural field 20 towards the inside of the machine 10. Additionally, as shown in Figure 1, the projection roller 38 may include a plurality of fins 40 intermittently mounted that help to force the sugar cane stems down. As roll 38 is rotated during the harvest, the sugarcane stems that have been tipped over by tipping roll 36 are separated and subsequently tipped over by roll 38 as machine 10 continues to be moved forward with respect to field 20.

[0029] Ainda com referência à Figura 1 , a máquina 10 pode também incluir um conjunto de corte de base 42 posicionado atrás do rolo 38. Como é geralmente entendido, o conjunto de corte de base 42 pode incluir lâminas (não mostradas) para cortar os caules de cana-de-açúcar conforme a cana é colhida. As lâminas, localizadas na periferia do conjunto 42, podem ser giradas por um motor hidráulico (não mostrado) acionado pelo sistema hidráulico da máquina. Adicionalmente, em diversas realizações, as lâminas podem ser anguladas para baixo para cortar a base da cana-de-açúcar conforme a cana é tombada pelo rolo 38. [0029] Still referring to Figure 1, the machine 10 may also include a base cutter assembly 42 positioned behind the roller 38. As is generally understood, the base cutter assembly 42 may include blades (not shown) for cutting the sugar cane stems as the cane is harvested. The blades, located on the periphery of the set 42, can be rotated by a hydraulic motor (not shown) driven by the machine's hydraulic system. Additionally, in several embodiments, the blades can be angled downwards to cut the base of the sugar cane as the cane is tipped over by the roller 38.

[0030] Além disso, como representado na Figura 1 , a máquina 10 pode incluir um conjunto de um ou mais rolos transportadores 44 localizado a jusante do conjunto de corte de base 42 para mover os caules cortados de cana-de- açúcar a partir do conjunto de corte de base 42 ao longo da trajetória de processamento. Conforme mostrado na Figura 1 , o conjunto de rolo transportadores 44 pode incluir uma pluralidade de rolos inferiores 46 e uma pluralidade de rolos superiores 48. Conforme a cana-de-açúcar é transportada através do conjunto de rolos transportadores 44, resíduos (por exemplo, pedras, sujeira e/ou similares) podem ser também transportados ou cair através dos rolos inferiores 46 sobre o campo 20. [0030] In addition, as shown in Figure 1, the machine 10 may include a set of one or more conveyor rollers 44 located downstream of the base cutter assembly 42 to move the cut sugarcane stems from the base cutting assembly 42 along the processing path. As shown in Figure 1, the conveyor roller set 44 may include a plurality of lower rollers 46 and a plurality of upper rollers 48. As the sugar cane is transported through the conveyor roller set 44, waste (for example, stones, dirt and / or the like) can also be transported or fall through the lower rollers 46 onto the field 20.

[0031] Adicionalmente, como é possível observar na Figura 1 , a máquina 10 pode incluir um conjunto picador 50 localizado na extremidade a jusante do conjunto de rolo transportadores 44 (por exemplo, adjacente aos rolos transportadores inferiores e superiores mais traseiros 46, 48). Em geral, o conjunto picador 50 pode ser usado para cortar ou picar os caules colhidos de cana-de-açúcar em pedaços ou “fragmentos” 51 menores que podem, por exemplo, medir 15,24 centímetros (seis (6) polegadas), também chamados de toletes ou rebolos. Os fragmentos 51 podem, então, ser impulsionados na direção de um conjunto elevador 52 da máquina 10 para serem coletados em um receptor externo ou dispositivo de armazenamento (não mostrado), por exemplo, os transbordos e caçambas. [0031] Additionally, as can be seen in Figure 1, the machine 10 may include a chipper assembly 50 located at the downstream end of the conveyor roller assembly 44 (for example, adjacent to the lower and upper upper conveyor rolls 46, 48) . In general, the chopper set 50 can be used to cut or chop the stalks harvested from sugar cane into smaller pieces or “fragments” 51 that can, for example, measure 15.24 centimeters (six (6) inches), also called blanks or grinding wheels. The fragments 51 can then be propelled towards an elevator assembly 52 of the machine 10 to be collected in an external receiver or storage device (not shown), for example, overflows and buckets.

[0032] Conforme é geralmente entendido, pedaços de resíduos 53 (por exemplo, poeira, sujeita, folhas, etc.) separados dos fragmentos de cana-de- açúcar 51 podem ser expelidos da máquina 10 através de um extrator primário 54, que é localizado atrás do conjunto picador 50 e é orientado para direcionar os resíduos 53 para fora da máquina 10. Adicionalmente, um ventilador 56 pode ser montado no extrator primário 54 para gerar uma força de sucção ou vácuo suficiente para capturar os resíduos 53 e forçar esses resíduos 53 através do extrator primário 54. Os resíduos 53 são, então, direcionados para fora e geralmente na direção contrária da máquina 10 por meio de uma saída do extrator primário 54. Os fragmentos separados 51 e mais pesados que os resíduos 53 que estão sendo expulsos pelo extrator 54, podem, então, cair para o conjunto elevador 52. [0032] As is generally understood, pieces of waste 53 (eg, dust, subject, leaves, etc.) separated from the sugar cane fragments 51 can be expelled from the machine 10 through a primary extractor 54, which is located behind the chipper assembly 50 and is oriented to direct the waste 53 out of the machine 10. Additionally, a fan 56 can be mounted on the primary extractor 54 to generate a sufficient suction or vacuum force to capture the waste 53 and force this waste 53 through the primary extractor 54. Residues 53 are then directed outward and generally in the opposite direction of the machine 10 via an outlet from the primary extractor 54. The separated fragments 51 and heavier than the residues 53 being expelled by the extractor 54, can then fall to the elevator assembly 52.

[0033] De acordo com este relatório descritivo, o conjunto elevador 52 deve ser entendido como compreendendo, em geral, uma estrutura de alojamento de elevador 58 e um elevador 60 que se estende dentro da referida estrutura de alojamento do elevador 58 entre uma extremidade proximal inferior 62 e uma extremidade distai superior 64. A extremidade proximal inferior 62 sendo fixada à máquina 10 e a extremidade distai superior 64 tendo uma abertura 82 para descarga do material colhido. [0033] According to this specification, the elevator assembly 52 is to be understood as comprising, in general, an elevator housing structure 58 and an elevator 60 that extends within said elevator housing structure 58 between a proximal end lower 62 and an upper distal end 64. The lower proximal end 62 being attached to the machine 10 and the upper distal end 64 having an opening 82 for discharging the harvested material.

[0034] Em realizações adicionais ou alternativas, o elevador 60 pode incluir uma corrente ou esteira transportadora 66 e uma pluralidade de pás ou taliscas 68 acopladas ou espaçadas de maneira uniforme na corrente 66. As taliscas 68 podem ser configuradas para segurar os fragmentos de cana-de- açúcar 51 no elevador 60 conforme os fragmentos 51 são elevados até a porção superior 70 do elevador 60. Adicionalmente, o elevador 60 pode incluir rodas dentadas inferiores e superiores 72, 74 posicionadas em torno das extremidades proximal e distai 62, 64, respectivamente. Conforme mostrado na Figura 1 , um motor de elevador 76 pode ser acoplado a uma das rodas dentadas (por exemplo, a roda dentada superior 74) para acionar a corrente 66, permitindo assim que a corrente 66 e as taliscas 68 viajem em um ciclo sem fim entre as extremidades proximal e distai 62, 64 do elevador 60. [0034] In additional or alternative embodiments, the elevator 60 may include a chain or conveyor belt 66 and a plurality of shovels or flats 68 coupled or evenly spaced in the chain 66. The flats 68 can be configured to hold the cane fragments sugar 51 in elevator 60 as fragments 51 are lifted up to the portion upper 70 of elevator 60. Additionally, elevator 60 may include lower and upper sprockets 72, 74 positioned around the proximal and distal ends 62, 64, respectively. As shown in Figure 1, an elevator motor 76 can be coupled to one of the sprockets (for example, the upper sprocket 74) to drive the chain 66, thus allowing the chain 66 and the cleats 68 to travel in a cycle without end between the proximal and distal ends 62, 64 of elevator 60.

[0035] Além disso, pedaços de resíduos 53 (por exemplo, poeira, sujeira, folhas, etc.) separados dos fragmentos de cana-de-açúcar 51 podem ser expelidos da máquina 10 através de um extrator secundário 78 acoplado à extremidade traseira da estrutura de alojamento do elevador 58. Conforme mostrado na Figura 1 , o extrator secundário 78 pode estar situado de maneira adjacente à extremidade distai 64 do elevador 60 e pode ser orientado para direcionar os resíduos 53 para fora a partir da máquina 10. Adicionalmente, um ventilador 80 pode ser montado no extrator secundário 78 para gerar uma força de sucção ou vácuo suficiente para extrair os resíduos 53 e forçar esses resíduos 53 através do extrator secundário 78. Os fragmentos separados 51 , mais pesados que os resíduos 53 expelidos através do extrator 78, podem, então, cair da extremidade distai 64 do elevador 60. Tipicamente, os fragmentos 51 podem cair através de uma abertura de descarga 82 do conjunto elevador 52 em um dispositivo de armazenamento externo (não mostrado), tal como um carro, um transbordo, uma caçamba etc. [0035] In addition, pieces of waste 53 (for example, dust, dirt, leaves, etc.) separated from the sugar cane fragments 51 can be expelled from the machine 10 through a secondary extractor 78 coupled to the rear end of the the housing structure of the elevator 58. As shown in Figure 1, the secondary extractor 78 can be located adjacent to the distal end 64 of the elevator 60 and can be oriented to direct the waste 53 out of the machine 10. Additionally, a fan 80 can be mounted on secondary extractor 78 to generate sufficient suction or vacuum force to extract waste 53 and force that waste 53 through secondary extractor 78. Separate fragments 51, heavier than waste 53 expelled through extractor 78 , may then fall from the distal end 64 of the elevator 60. Typically, fragments 51 may fall through a discharge opening 82 of the elevator assembly 52 into an air device external storage (not shown), such as a car, an overflow, a bucket, etc.

[0036] Durante a operação, a máquina 10 é percorrida por todo o campo agrícola 20 para colher cana-de-açúcar ou qualquer outra planta alta e cauleosa. Após a altura do cortador de pontas 22 ser ajustada (se for utilizado) por meio dos braços 28, o disco aglutinador 24 no conjunto de cortador de pontas 22 pode funcionar de maneira a aglutinar as pontas de cana-de-açúcar conforme a máquina 10 procede através do campo 20, enquanto o disco cortador 26 corta as pontas folhosas dos caules de cana-de-açúcar para despejá-las ao longo de ambos os lados da máquina 10. Conforme os caules entram no divisor de linha 30, as sapatas 34 podem configurar a largura da operação para determinar a quantidade de cana-de-açúcar que entra na garganta da máquina 10, seja de modo fixo ou ajustável. Os pirulitos 32 aglutinam então os caules na entrada da máquina para permitir que o rolo tombador 36 curve os caules para baixo em conjunto com a ação do rolo alimentador 38. Uma vez que os caules são posicionados em ângulo conforme mostrado na Figura 1 , o conjunto de corte de base 42 pode, então, cortar a base dos caules do campo 20. Os caules cortados são, então, direcionados ao conjunto de rolos transportadores 44. [0036] During operation, machine 10 is traversed throughout the agricultural field 20 to harvest sugar cane or any other tall and stemy plant. After the height of the tip cutter 22 is adjusted (if used) by means of the arms 28, the agglutinating disc 24 in the tip cutter assembly 22 can work in order to agglutinate the sugarcane tips according to the machine 10 proceeds through field 20, while cutter disk 26 cuts through the leafy tips of the sugarcane stems to dump them along both sides of the machine 10. As the stems enter the line divider 30, the shoes 34 can set the width of the operation to determine the amount of cane -sugar that enters the throat of the machine 10, either in a fixed or adjustable way. The lollipops 32 then agglutinate the stems at the entrance of the machine to allow the tipping roller 36 to curve the stems down together with the action of the feed roller 38. Once the stems are positioned at an angle as shown in Figure 1, the set base cutter 42 can then cut the base of the stems of field 20. The cut stems are then directed to the set of conveyor rollers 44.

[0037] Os caules cortados de cana-de-açúcar são transportados para trás pelos rolos transportadores 46, 48 que comprimem os caules e a matéria colhida. Na extremidade a jusante do conjunto de rolos transportadores 44, o conjunto picador 50 corta ou pica os caules compactados de cana-de-açúcar em pedaços ou fragmentos 51. Resíduos transportados 53 (por exemplo, poeira, sujeira, folhas, etc.) separados dos fragmentos de cana-de-açúcar 51 são, então, extraídos através do extrator primário 54 usando a sucção criada pelo ventilador 56. Os fragmentos separados/lavados 51 caem, então, para o conjunto elevador 52 e viajam para cima por meio do elevador 60 a partir da sua extremidade proximal 62 até a extremidade distai 64. Durante a operação normal, uma vez que os fragmentos 51 alcançam a extremidade distai 64 do elevador 60, os fragmentos 51 caem através da abertura de descarga 82 até um dispositivo de armazenamento externo. Similar ao extrator primário 54, resíduos são soprados para fora da máquina 10 através do extrator secundário 78 com o auxílio do ventilador de extrator 80. [0037] The cut stalks of sugar cane are transported backwards by the conveyor rollers 46, 48 which compress the stems and the harvested material. At the downstream end of the conveyor roller set 44, the chopper assembly 50 cuts or dices the compacted stalks of sugar cane into pieces or fragments 51. Waste transported 53 (eg, dust, dirt, leaves, etc.) separated of the sugar cane fragments 51 are then extracted through the primary extractor 54 using the suction created by the fan 56. The separated / washed fragments 51 then fall to the elevator assembly 52 and travel upwards through the elevator 60 from its proximal end 62 to distal end 64. During normal operation, once fragments 51 reach the distal end 64 of elevator 60, fragments 51 fall through the discharge opening 82 to an external storage device . Similar to primary extractor 54, waste is blown out of machine 10 through secondary extractor 78 with the aid of extractor fan 80.

[0038] Uma máquina colhedora 10, tal como descrita acima, pode ser, por exemplo, uma máquina conhecida no estado da técnica, tal como a colheitadeira de cana produzida pela CNH Industrial N.V. e comercializada com a marca Case IH. [0038] A harvester machine 10, as described above, can be, for example, a machine known in the prior art, such as a harvester cane produced by CNH Industrial NV and marketed under the Case IH brand.

[0039] Dessa forma, com base no acima relatado, e com referência as demais figuras, observa-se que a plataforma de manutenção 100, de acordo com a presente invenção, é formada por uma estrutura de montagem 101 que é fixada ao chassi 12, e na qual é montado um assoalho basculante 110 através de um eixo de pivotamento 102 previsto em sua porção posterior e por um conjunto atuador 120 previsto em sua porção frontal, sendo que esse conjunto atuador 120 compreende ao menos duas posições pré-definidas (P1 e P2) que correspondem, respectivamente, às condições desmontada e montada da presente plataforma de manutenção 100. Mais particularmente, estas posições pré-definidas são configuradas para que na primeira posição (P1 ) o referido assoalho basculante 110 encontra-se inclinado a partir do topo da máquina 10, enquanto na segunda posição (P2) o referido assoalho basculante 110 encontra- se nivelado ao topo da máquina 10. [0039] Thus, based on the above, and with reference to the other figures, it is observed that the maintenance platform 100, according to the present invention, is formed by an assembly structure 101 that is fixed to the chassis 12 , and on which a tilting floor 110 is mounted through a pivot axis 102 provided in its rear portion and by an actuator assembly 120 provided in its front portion, and that actuator assembly 120 comprises at least two predefined positions (P1 and P2), which correspond, respectively, to the disassembled and assembled conditions of the present maintenance platform 100. More particularly, these pre-defined positions are configured so that in the first position (P1) said tilting floor 110 is inclined from the top of the machine 10, while in the second position (P2) said tilting floor 110 is flush with the top of the machine 10.

[0040] Opcionalmente, segundo uma concretização possível de montagem da presente invenção, e dependendo da configuração do chassi 12 da máquina 10, a estrutura de montagem 101 pode compreender ao menos um braço de sustentação 103, fixado ao chassi 12, tendo por finalidade promover o aumento da resistência e estabilidade da presente plataforma de manutenção 100. [0040] Optionally, according to a possible embodiment of the present invention, and depending on the configuration of the chassis 12 of the machine 10, the assembly structure 101 can comprise at least one support arm 103, fixed to the chassis 12, with the purpose of promoting increasing the strength and stability of the present maintenance platform 100.

[0041] Em uma montagem particular da presente invenção, o referido assoalho basculante 110 pode compreender uma extensão inferior 111 que pode ser, segundo uma configuração mais particular, disposta angularmente em relação ao referido assoalho basculante 110, de modo a formar uma espécie de aba protetora, quando a plataforma de manutenção 100 encontra-se na condição desmontada, que acaba assumindo uma configuração paralela ao chassi 12 para, com isso, evitar que a palha entre na região abaixo do assoalho basculante 110 e fique em contato com os componentes instalados abaixo da plataforma de manutenção 100. [0041] In a particular assembly of the present invention, said tilting floor 110 can comprise a lower extension 111 which can, according to a more particular configuration, be angularly arranged with respect to said tilting floor 110, so as to form a kind of flap protective, when the maintenance platform 100 is in the disassembled condition, which ends up assuming a configuration parallel to the chassis 12 in order to prevent the straw from entering the region below the tilting floor 110 and stay in contact with the components installed below the maintenance platform 100.

[0042] De acordo com realizações particulares da presente invenção, o referido conjunto atuador 120 é formado por um eixo superior 121 , conectado de modo pivotável ao assoalho basculante 110, e um eixo inferior 122, o qual interage com ao menos um suporte 123, sendo que ambos os eixos 121 e 122 são dispostos paralelamente e conectados através de ao menos uma haste 124 e, mais particularmente por duas hastes 124 dispostas nas extremidades dos referidos eixos 121 , 122. Mais particularmente, o referido ao menos um suporte 123 compreende pelo menos dois recessos 123a, os quais estabelecem as posições pré-definidas (P1 , P2) através da interação com o referido eixo inferior 122. [0042] According to particular embodiments of the present invention, said actuator assembly 120 is formed by an upper axis 121, pivotably connected to the tilting floor 110, and a lower axis 122, which interacts with at least one support 123, both axes 121 and 122 being arranged in parallel and connected via at least one rod 124 and, more particularly by two rods 124 arranged at the ends of said axes 121, 122. More particularly, said at least one support 123 comprises at least minus two recesses 123a, which establish the pre-defined positions (P1, P2) through interaction with said lower axis 122.

[0043] Segundo uma outra concretização opcional da presente invenção, o conjunto atuador 120 compreende dois suportes 123 dispostos nas laterais da estrutura de montagem 101 , o que permite aumentar a capacidade de carga, mas principalmente melhorar a estabilidade da plataforma de manutenção 100, principalmente quando a mesma se encontra na condição montada. [0043] According to another optional embodiment of the present invention, the actuator assembly 120 comprises two supports 123 arranged on the sides of the assembly structure 101, which allows to increase the load capacity, but mainly to improve the stability of the maintenance platform 100, mainly when it is in the assembled condition.

[0044] Alternativamente, conforme uma outra realização da presente invenção, o referido conjunto atuador 120 pode compreender mecanismos mais sofisticados e automatizados para facilitar a movimentação do referido assoalho basculante entre a posição desmontada e montada. Por exemplo, o conjunto atuador 120 pode compreender componentes mecânicos, hidráulicos, pneumáticos, elétricos e eletrónicos, como pistões, molas, amortecedores, válvulas, eletroválvulas, etc. os quais são capazes de promover a movimentação das hastes 124 com o eixo inferior 122 entre as posições pré-definidas (P1 , P2) determinadas pelo ao menos um suporte 123. [0044] Alternatively, according to another embodiment of the present invention, said actuator assembly 120 may comprise more sophisticated and automated mechanisms to facilitate the movement of said tilting floor between the disassembled and assembled position. For example, actuator assembly 120 may comprise mechanical, hydraulic, pneumatic, electrical and electronic components, such as pistons, springs, shock absorbers, valves, solenoids, etc. which are capable of promoting the movement of the rods 124 with the lower axis 122 between the pre-defined positions (P1, P2) determined by at least one support 123.

[0045] Dessa forma, como deve ser apreciado pelos técnicos no assunto, as posições (P1 , P2) são definidas quando as extremidades do eixo inferior 122 são ancoradas nos respectivos recessos 123a dos ditos suportes 123, sendo que a primeira posição (P1 ), onde o assoalho basculante 110 encontra-se inclinada, é voltada para quando a máquina 10 está em operação em campo e, nessa posição, torna-se possível assegurar que a palha, proveniente por exemplo do cortador de pontas 22 da máquina, deslize sobre o assoalho basculante 110 e seja direcionada para o campo, impedindo que a palha fique acumulada no topo da máquina e, com isso, evita-se a obstrução das passagens de ar dos trocadores de calor do sistema de arrefecimento, por exemplo. Por outro lado, a segunda posição (P2), onde o assoalho basculante 110 encontra- se nivelado ao topo da referida máquina 10, é voltada para quando a máquina está parada e o operador necessita fazer alguma intervenção nos componentes instalados no topo da referida máquina, provendo um maior espaço para que o operador se movimente com segurança. [0045] In this way, as it should be appreciated by the technicians in the subject, the positions (P1, P2) are defined when the ends of the lower axis 122 are anchored in the respective recesses 123a of said supports 123, and the first position (P1), where the tilting floor 110 is inclined, is turned to when the machine 10 is in operation in the field and, in that position, it becomes it is possible to ensure that the straw, for example from the machine's tip cutter 22, slides over the tilting floor 110 and is directed towards the field, preventing the straw from accumulating on the top of the machine and thereby preventing obstruction the air passages of the cooling system heat exchangers, for example. On the other hand, the second position (P2), where the tilting floor 110 is level with the top of said machine 10, is facing when the machine is stopped and the operator needs to make some intervention on the components installed on the top of said machine , providing greater space for the operator to move safely.

[0046] Adicionalmente, e conforme acima comentado, a presente invenção refere-se também a uma máquina colhedora de plantas altas e cauleosas que compreende um chassi 12 montado sobre rodas (14, 16) ou esteiras, um motor, uma cabine de operador (18), sendo que na região de topo do referido chassi 12 é instalada uma plataforma de manutenção 100 configurada de acordo com as características da invenção acima definida, de modo que a referida plataforma pode assumir ao menos duas posições pré- definidas (P1 , P2), nas quais a primeira posição (P1 ) determina que o assoalho basculante 110 da referida plataforma 100 esteja inclinado a partir do topo da máquina 10, e a segunda posição (P2) determina que o referido assoalho basculante 110 esteja nivelado com o topo da máquina 10. [0046] Additionally, and as commented above, the present invention also relates to a tall and stemy harvester machine comprising a chassis 12 mounted on wheels (14, 16) or tracks, an engine, an operator's cabin ( 18), and in the top region of said chassis 12, a maintenance platform 100 is configured, configured according to the characteristics of the invention defined above, so that said platform can assume at least two predefined positions (P1, P2 ), in which the first position (P1) determines that the tilting floor 110 of said platform 100 is inclined from the top of the machine 10, and the second position (P2) determines that said tilting floor 110 is level with the top of the machine. machine 10.

[0047] De acordo com concretizações possíveis da presente invenção, a referida máquina colhedora de plantas altas e cauleosas é projetada e desenvolvida para executar a colheita de cana-de-açúcar e/ou sorgo-doce. [0048] Por fim, diante de todo o acima exposto, vale ressaltar que a presente descrição tem como objetivo apenas apresentar e definir de modo exemplificativo realizações da plataforma de manutenção e da máquina colhedora, de acordo com os objetos da presente invenção. Logo, como bem devem apreciar os técnicos no assunto, diversas modificações e combinações de elementos e detalhes equivalentes são possíveis sem, com isso, fugir do escopo de proteção definido pelas reivindicações anexas. [0047] In accordance with possible embodiments of the present invention, the said tall and stem plant harvesting machine is designed and developed to perform the harvest of sugarcane and / or sweet sorghum. [0048] Finally, in view of all of the above, it is worth mentioning that the purpose of the present description is only to present and define in an exemplary way the realizations of the maintenance platform and the harvester, according to the objects of the present invention. Therefore, as the technicians in the subject must appreciate, several modifications and combinations of elements and equivalent details are possible without, therefore, escaping the scope of protection defined by the attached claims.
