Description
Dl SPOSI ÇÃO CONSTRUTI VA EM CAPI NADEI RA PORTÁTI L Dl CONSTRUCTIVE SPOSITION IN CAPI NADEI RA PORTABLE L
Trata-se de disposição construtiva em capinadeira portátil em que o dispositivo mecânico capinador é formado por um conjunto de enxadas rotativas, acionadas por motor de combustão interna ou motor elétrico, que substitui a capinagem manual no preparo do solo para plantio em áreas confinadas. It is a constructive arrangement in a portable weeding machine where the mechanical weeding device is formed by a set of rotary hoes, driven by internal combustion engine or electric motor, which replaces manual weeding in the preparation of soil for confined areas.
Para fins deste documento de patente, a expressão "capinar" entende-se como retirar, por ação mecânica, uma camada superficial de solo com espessura aproximada de 5cm. Para grandes áreas de plantio utiliza-se o Arado que é um instrumento que serve para lavrar os campos, revolvendo a terra com o objetivo de descompactá-la e, assim, viabilizar um melhor desenvolvimento das raízes das plantas. Também enterra restos de culturas agrícolas anteriores ou ervas daninha porventura existente. Existem plantios em que não é viável o uso de máquinas pesadas como tratores e equipamentos de grande porte, como o arado de aiveca ou de disco tracionados por trator, para capinar durante o preparo e limpeza do solo. Como é o caso de algumas plantações por serem frágeis, ou em áreas pequenas, ou em terrenos acidentados, ou estarem plantadas em locais junto com outras culturas; ainda em casos de plantações em meio a árvores ou florestas. Outra constatação a considerar é a limitação cada vez maior do uso de agrotóxicos no extermínio de plantas ou matos indesejados, devido seus possíveis riscos a saúde e também ao seu impacto ambiental gerado na região do plantio, além da desvalorização, no mercado, dos produtos ali industrializados, pela concorrência dos produtos "sem agrotóxicos". Nesses tipos de plantações, a capinagem manual é a mais indicada para a limpeza dos plantios, porém é um
método de alto custo, pois necessita de várias pessoas para preparo de uma pequena área, o que demanda custos com mão de obra e um maior tempo na realização do serviço. A enxada manual constituída por uma lâmina e cabo para uso manual já pertence ao estado da técnica de longa data. Por outro lado, a tecnologia do corte de grama evoluiu e hoje tem equipamento cortador de grama estruturalmente montado em um carrinho de quatro rodas motorizado, com lâminas de corte montadas sob a base. As lâminas, posicionadas em plano paralelo ao solo, são montadas de forma radial ao eixo vertical do motor de acionamento; só serve para cortar grama, mas não tem a função de capinar de forma similar à enxada manual. For the purposes of this patent document, the term "weeding" means the mechanical removal of a surface layer of soil approximately 5 cm thick. For large areas of cultivation, the plow is used as a tool to plow the fields, turning the soil in order to decompress it and thus enable a better development of plant roots. It also buries remnants of previous crops or weeds that may exist. There are plantings where it is not feasible to use heavy machinery such as tractors and large equipment such as a tractor-mounted moldboard or disc plow for weeding during tillage and tillage. As is the case with some plantations because they are fragile, or in small areas, or on rough terrain, or are planted in places with other crops; even in cases of plantations amid trees or forests. Another finding to consider is the increasing limitation of the use of pesticides in the extermination of unwanted plants or shrubs, due to their possible health risks and also to their environmental impact generated in the planting region, besides the devaluation in the market of the products there. industrialized, by the competition of products "without pesticides". In these types of plantations, manual weeding is the most suitable for cleaning the plantations, but it is a This is a high cost method because it requires several people to prepare a small area, which demands labor costs and a longer time to perform the service. The hand hoe consisting of a blade and handle for manual use already belongs to the state of the art. On the other hand, mowing technology has evolved and today has lawnmower equipment structurally mounted on a motorized four-wheeled cart with mowers mounted under the base. The blades, positioned in a plane parallel to the ground, are mounted radially to the vertical axis of the drive motor; It is only for mowing but does not have the function of weeding similar to the hand hoe.
O documento de patente, denominado GREEN MOWER, depositado sob numero CN202335235 descreve uma capinadeira abridora de vala para plantio linear. Utiliza um disco posicionado em plano perpendicular ao solo, com periferia dentada, similar a uma serra circular e os "dentes" do disco abrem o sulco em forma de vala no solo. O documento de patente chinês "One kind of grass lawn cutter", numero Cn202697265, descreve equipamento cortador de grama com lamina de corte paralela ao solo; não atua como capinadeira. The patent document, called GREEN MOWER, filed under CN202335235 describes a linear planting trench opener. It uses a disk positioned perpendicular to the ground with a notched periphery, similar to a circular saw, and the "teeth" of the disk open the ditch-shaped groove in the ground. Chinese patent document "One kind of grass lawn cutter", Cn202697265, describes lawn mower equipment with parallel-to-ground cutting blade; It does not act as weeding.
A "DISPOSIÇÃO CONSTRUTIVA EM CAPINADEIRA PORTÁTIL", descrita neste relatório, se caracteriza pelo conjunto de lâminas rotativas instaladas em uma estrutura de carrinho manual com rodas. O capinador portátil possui estrutura semelhante a uma estrutura de "máquina de cortar grama", sendo que as lâminas rotativas giram em torno de um eixo horizontal. As lâminas golpeiam o solo de forma similar a de uma enxada manual; o material arrancado do solo é jogado contra um anteparo quebrando os torrões e separando a terra residual das raízes das plantas. Faz a capinagem e a trituração de plantas, com até 15 cm. de altura. O acionamento da rotação das lâminas se dá por um motor instalado sobre o equipamento. Com essa forma construtiva, o capinador torna-
se portátil, desmontável e de manutenção baixa. Sua forma de operação é similar a de um cortador de grama motorizado, sendo empurrado/puxado nos locais onde se quer fazer a limpeza do solo. Com a utilização do equipamento de "capinagem e preparador de plantio portátil", um único operador pode fazer aproximadamente o trabalho de 10 (dez) pessoas, reduzindo tempo e custo da mão de obra. The "LAPTOP BUILDING CONSTRUCTIVE ARRANGEMENT" described in this report is characterized by the set of rotating blades installed in a hand-wheeled trolley frame. The portable weeding has a structure similar to a "lawnmower" structure, with the rotating blades rotating about a horizontal axis. The blades strike the soil similar to a hand hoe; material torn from the ground is thrown against a screen breaking the clods and separating the residual soil from the roots of the plants. Do weeding and shredding plants up to 15 cm. high. The rotation of the blades is triggered by a motor installed on the equipment. With this constructive form, the weeding becomes if portable, detachable and low maintenance. Its operation is similar to that of a motorized lawn mower, being pushed / pulled where the soil is to be cleaned. Using "portable weeding and tillage" equipment, a single operator can do approximately 10 (10) people work, reducing labor time and cost.
