Abstract

"CONJUNTO DE SUPORTE DE DESENGATE POR MOLA PARA UM IMPLEMENTO". Um suporte para desengate por mola para um implemento agrícola inclui uma mola helicoidal livremente e unicamente comprimida entre uma superfície superior de encontro de mola no apoio de montagem e uma superfície inferior de encontro de mola em um fundido, o qual é conectado por meio de um pivó transversal a um apoio de montagem. Uma haste de suporte de ferramenta é aparafusada ao fundido e pressionada para baixo, para uma posição de trabalho no solo, por meio da mola. O fundido inclui um batente integral, que se estende para adiante a partir do pivó. O batente entra em contato com o fundo do suporte quando a haste estiver na posição de trabalho no solo, de modo que uma conexão de tração entre o suporte e o fundido é eliminada. Uma guia de mola através das espiras é também eliminada. Uma força de desengate inicial relativamente alta impede desengatamento não desejado da haste e impede afrouxamento na haste pivó, de modo que a posição lateral da ferramenta seja mantida. A superfície de encontro de mola no fundido inclui uma projeção para recepção de mola para auxiliar em se manter a posição da mola em relação à haste. A projeção tem um rasgo para receber uma ferramenta especial para se comprimir a mola, para desmontagem e remontagem do suporte. A ferramenta especial também facilita a substituição de um conjunto de bucha e luva no pivó com apenas uma desmontagem parcial.
