Abstract

A floating frame has two close semi-portions articulated in between by a fixed joint and mounted to the frame of an agricultural machinery in which counterweights are mounted to provide stability. A mechanical shock absorber is articulated to the semi-portions by fixed joints such that the counterweights resist irregularities in the area and prevent transmission of the irregularities to a tractor. A regulator controls the rigidity of the mechanical shock absorber such that the suspension can adapt to the different work conditions and to different agricultural machineries.

Description

Suspensión mecánica, para maquinaria agrícola.Mechanical suspension, for machinery agricultural.

El objeto del invento es una suspensión mecánica, para maquinaria agrícola y, más en concreto, una suspensión mecánica para tractores, que emplea contrapesos de inercia.The object of the invention is a suspension mechanical, for agricultural machinery and, more specifically, a mechanical suspension for tractors, which uses counterweights of inertia.

Convencionalmente, la maquinaria agrícola se dispone en bastidores y es cautiva de un tractor del que depende para que pueda funcionar (pues necesita siempre un elemento motriz). La Patente WO92/ 09190, por ejemplo, se refiere a maquinaria agrícola de este tipo.Conventionally, agricultural machinery is It has racks and is captive of a tractor on which it depends so that it can work (it always needs an element motor) WO92 / 09190, for example, refers to Agricultural machinery of this type.

Cuando se transporta la maquinaria agrícola, su balanceo es perjudicial para el tractor. Consecuentemente hay que reducirlo y, a ser posible, elimi-
narlo.When agricultural machinery is transported, its balancing is detrimental to the tractor. Consequently, it must be reduced and, if possible, eliminated
tell him

Una forma de eliminarlo consiste en disponer contrapesos con suspensión.One way to eliminate it is to have counterweights with suspension.

El solicitante ha desarrollado una suspensión de funcionamiento totalmente mecánico y que funciona siempre totalmente independientemente del propio tractor. Se caracteriza porque consta de:The applicant has developed a suspension of fully mechanical operation and always fully functioning regardless of the tractor itself. It is characterized because it consists from:

a) un bastidor flotante, estructurado en dos semi-partes, unidas articuladamente entre sí mediante articulación fija y que, respectivamente, se montan en el bastidor de la maquinaria agrícola y montan en sí mismas al contrapeso que proporciona estabilidad a dicha maquinaria agrícola;a) a floating frame, structured in two semi-parts, articulated together by fixed articulation and that, respectively, are mounted on the frame of agricultural machinery and assemble themselves to counterweight that provides stability to said machinery agricultural;
