The mechanism of pressure regulator for application in the planting line machinery and equipment in general agru00eccolas

摘要

Which mainly aims at regular, simple, practical and rapid, the increase and decrease of the pressure exerted by the line on the ground, and, to this end, incorporates a crank arm, which is housed in the mounting hole that is practiced in the lower arm of the pantograph, this being said br Steel crank fixed, on the one hand, an adapter that retains one of the end of the spring line.Whose opposite end is fixed to the support of the pantograph, and the said crank arm fixed on the side opposite in a range of pressure, which is provided for hexagonal pin, which may be made with the aid of tool itself, the choice of the intensity of pressure. Balho line, and this choice, preferably made of manual way, through heat knob,Disposed above the scale, and the locking of the scale obtained, automatically, by radial displacement of brake in relation to said scale, and that this so-called lock is also pivoted on the lower arm of the pantograph, and can be controlled by the handle.
