ANTECEDENTES DA INVENÇÃO E TÉCNICA ANTERIOR BACKGROUND OF THE INVENTION AND PREVIOUS TECHNIQUE
Atualmente, a criação de cavalos depende muito da qualidade das instalações utilizadas nesta atividade. Sendo que toda a criação deve dispor de instalações para confinamento desses animais em baias ou boxes. Este tipo de instalação, conhecida como estábulo, é de grande importância para o bom desenvolvimento e a manutenção da saúde dos cavalos. A higiene dentro das baias é de extrema importância para a saúde dos animais e neste aspecto o piso tem um papel primordial. Existem vários tipos de pisos que os criadores utilizam nas baias, desde o piso de cimento recoberto com serragem ou maravalha, até pisos sintéticos, de borracha ou materiais plásticos. Porém o mais utilizado são os recobertos/forrados por maravalha devido ao seu custo de manutenção. Entende-se por ma- ravalha toda a raspa, fragmento, pedacinho da madeira, resíduo de beneficiamento de qualquer tipo de madeira. Currently, horse breeding depends very much on the quality of the facilities used in this activity. Since all breeding must have facilities for confinement of these animals in stalls or pits. This type of installation, known as a stable, is of great importance for the proper development and maintenance of horses' health. The hygiene inside the bays is of extreme importance for the health of the animals and in this aspect the floor plays a primordial role. There are several types of floors that designers use in the stalls, from cement-coated or sawdust-cement flooring to synthetic, rubber or plastic flooring. However the most used are the covered / lined by shaving due to its cost of maintenance. By definition, the whole bark, fragment, small piece of wood, is the residue of any kind of wood.
Porém mesmo sendo mais económica, a troca diária de toda a maravalha, acaba gerando um custo alto na compra deste material, bem como necessita mais tempo para a remoção e troca de toda a maravalha que está no chão. But even though it is more economical, the daily exchange of all the woodwork, ends up generating a high cost in the purchase of this material, as well as it needs more time for the removal and exchange of all the shavings that are on the floor.
Esta limpeza constante do estábulo se faz necessária para garantir a saúde do animal, pensando nisto é que o autor sabendo da importância da limpeza e desinfecção constante do estábulo, a fim de impedir a proliferação de bactérias ou fungos e, sabendo das necessidades de se encontrar uma solução para reduzir os custos e o tempo de limpeza dos estábulos, partiu do princípio da peneiração como descrito no documento BR UM 5800188-3U2 que descreve um instrumento de peneiração, porém, aplicado de forma diferente e direcionado para outro tipo de resíduo. SUMÁRIO DA INVENÇÃO This constant cleaning of the stable is necessary to ensure the health of the animal, thinking of this is the author knowing the importance of constant cleaning and disinfection of the stable, in order to prevent the proliferation of bacteria or fungi and, knowing the needs of meeting a solution for reducing the costs and cleaning time of the stables, started from the screening principle as described in BR UM 5800188-3U2 which describes a sifting instrument, however, applied differently and directed to another type of residue. SUMMARY OF THE INVENTION
O autor uniu a ideia da peneiração com a associação da utilização de uma pá de coleta, como a descrita no documento BR PI 0605741-1A2, que trata de uma "PÁ E VASSOURA CONJUGADA PARA RECOLHER DEJETOS DE ANIMAIS E LIMPEZA DO SANITÁRIO PARA ANIMAIS", mudando, totalmente, o formato e a forma de aplicação, a fim de criar um instrumento de coleta e peneiração manual de maravalha, que possa ser utilizado dentro de um estábulo/baia para cavalos ou outros animais, com o objetivo, único, de peneirar, manualmente, grandes volumes de maravalha, para separar a mesma do excremento do animal. The author joined the idea of sifting with the association of the use of a collection blade, as described in BR PI 0605741-1A2, which deals with a "CONTAINED BIRD AND BROOM TO COLLECT ANIMAL DRAWINGS AND CLEANING OF ANIMAL SANITARY" , completely changing the shape and the form of application, in order to create a tool for collecting and sifting the wood, which can be used inside a stable / bay for horses or other animals, for the sole purpose of sifting, by hand, large volumes of wood, to separate it from the excrement of the animal.
Desta forma, o tratador pode entrar dentro do estábulo e, utilizando o instrumento aqui pleiteado, começar a peneirar toda a maravalha e remover somente as fezes do animal, que fica retida dentro do instrumento manual de peneirar. Tal procedimento elimina a necessidade de se trocar diariamente toda a maravalha de dentro do estábulo. In this way, the handler can enter inside the stable and, using the instrument pleaded here, begin to sift all the shaving and remove only the faeces of the animal, which is retained inside the manual sifting instrument. Such a procedure eliminates the need to change all the shavings from the inside of the stable daily.
Segundo o Conselho Regional de Medicina Veterinária, brasileiro, (CRMV) é recomendado a todo proprietário de cavalo a manutenção da baia do seu animal, sendo sugerida a limpeza de, até, duas vezes por dia, para proteger o local contra bactérias nocivas, afastando moscas, para proporcionar um ambiente limpo, seguro e saudável para o animal. According to the Regional Council of Veterinary Medicine, Brazilian, (CRMV) is recommended to all horse owners to maintain the bay of their animal, and it is suggested to clean up, even twice a day, to protect the site against harmful bacteria, flies, to provide a clean, safe and healthy environment for the animal.
O instrumento de peneiração manual, aqui pleiteado, poderá ser fabricado nos mais variados materiais, tais como os derivados de polímero e suas misturas ou metálico. The hand sieving instrument claimed herein may be manufactured from a variety of materials, such as polymer derivatives and mixtures thereof or metal.
O formato e distanciamento (malha) de abertura das grades, telas ou similares, para a passagem da maravalha e retenção dos excrementos dos animais, será determinado conforme a necessidade em sua comercialização. The format and distance (mesh) of opening the grids, screens or similar, for the passage of the shaving and retention of animal excrement, will be determined according to the need in its commercialization.
Outro objetivo da presente solicitação, é o de construir o instrumento, da combinação de uma pá formada por uma tela vazada para peneiramento, de fundo retangular alongado com uma parede posterior e paredes laterais, perpendicularmente posicionadas, projeta- das, de tal forma, para que facilite o trabalho do tratador para peneirar e separar toda a maravalha presente no piso do estábulo, das fezes do animal. Another object of the present application is to construct the instrument, from the combination of a blade formed by a hollow screen for sieving, with an elongated rectangular bottom with a rear wall and side walls, perpendicularly positioned, designed in such a way to which facilitates the work of the handler to sift and separate all the shavings present on the floor of the stable from the animal's faeces.
A obtenção deste formato de pá, pode ser por dobradura das paredes laterais e parede posterior ou no recorte da base, paredes laterais e parede posterior, em componentes independentes, montados, perpendicularmente, entre si e unidas as extremidades coincidentes por meio de grampos, enrolamento de fio ou soldagem, dentre outros. Da mesma forma, a haste metálica pode ser única, dobrada, ou em mono componentes solidarizados entre si, afim de suportar a estrutura da pá, conformada pela base, paredes laterais e posterior e tubo, unidos por meio de gra mpos, enrolamento de fio ou soldagem, dentre outros. The attainment of this blade shape may be by folding the sidewalls and back wall or in the cutout of the base, side walls and back wall, into independent components, mounted perpendicularly between one another and the mating ends joined together by means of clamps, winding of wire or welding, among others. Likewise, the metal rod may be single, folded, or in monolithic components joined together to support the blade structure, formed by the base, side and rear walls and tube, joined by means of grains, wire winding or welding, among others.
