Description

Mechanism for driving rods shellfish collection.

Object of the invention

The present invention relates to a mechanism which has been specially designed to drive a wand for the collection of mollusks, such as those involved in angazos or rakes

The object of the invention is to supply said rod an intermittent traction movement similar to that exercised by the fisherman in the collection of mollusks, freeing him from the considerable effort required for manual traction on the rod

The mechanism not only allows to automate the traction movements on the rod, but it is also trained to move a hacker to collect ropes or nets Complementary to the aforementioned rake.

Background of the invention

As is known, for the collection of mollusks, use anchors or rakes, provided with a rod of considerable length, so that the fisherman pulls with his hands from the said rod dragging the rake itself over the seabed, so that the mollusks turn out dragged by said rake.

This operation requires a very effort considerable by the fisherman in the handling of the rod.

The applicant is not aware of the existence of any mechanism that allows release in greater or lesser measure to the fisherman of this remarkable effort, which is the cause of body fatigue as well as illness and casualties due to injuries

Description of the invention

The mechanism proposed by the invention resolves in a fully satisfactory way the problem previously exposed, freeing the fisherman from physical exertion previously cited, so that this mechanism supplies the wand, so automatic, movements that reproduce very fortunately those exercised by the fisherman in the performance of his function as manual form

For this and more specifically, the mechanism it materializes in an eccentric cam, driven by a motor hydraulic or pneumatic, which through a connecting rod supplies the tilting movement to a lever, which and by its limb opposite to said crank joint joins an arm of traction provided with clamps or jaws for fixing the rod. The motor-eccentric assembly is mounted through a support on a base plate, to which a housing is integral crossed by the connecting rod and in which the axis of tilt for the lever, adjustable positioning axis by the existence in said multi-hole lever used selectively based on different depths and rake weights.

The said motherboard is in turn mounted on the deck of the boat through a small support rotating, to be able to work in the posture that at every moment require the sailor or fisherman.

On the axis of rotation of the cam it is mounted in addition to the latter a hacker that allows collection of ropes or nets, simultaneously to the drag of the wand.

Since said cam supplies the arm of traction an alternative longitudinal movement, that is in one and another sense, to: prevent the rod from moving forward and backward and get that only advance, the mentioned jaws are they materialize in deformable parallelograms, which press against the rod during the cam drag half cycle and opening releasing the rod in the other half cycle of said cam, that is when the traction arm moves towards the rake Properly said.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figure 1.- Shows a partial view in perspective of a mechanism for driving rods of collection of mollusks carried out in accordance with the purpose of the present invention, specifically in the absence of the traction arm that Participate in the mechanism.

Figure 2.- Shows a perspective opposed to that of the previous figure, in which if it is observed said traction arm.

Figure 3.- Shows an elevation view lateral of the kinematic chain established between the cam and the rod, in the absence of these two elements.

Figure 4.- Shows a representation schematic side elevation of the entire mechanism, to which it appears the corresponding rod attached.

Preferred Embodiment of the Invention

In view of the figures outlined you can Observe how the mechanism proposed by the invention is constituted from a base plate (1) mounted with freedom of vertical axis rotation on the deck of the vessel used for fishing, in order to allow the mechanism to be properly oriented according to the fisherman's criteria, base plate (1) on which It is mounted in turn, with the collaboration of an intermediate support (2), a driving group consisting of a cam (3) with a horizontal axis and a hauler (4) coaxial with said cam, both keyed on the shaft (5) of a hydraulic or pneumatic motor, hidden in figure 1 by the hatter himself (4).

To the rotating cam (3), at a point of its periphery (6) joins a connecting rod (7) that penetrates the breast of a housing (8) also attached to the base plate (1), connecting rod (7) that at its other end joins in turn articulated to a lever (9) mostly housed inside said housing (8) and tilting with respect to the latter by a point intermediate (10), specifically with the collaboration of an axis Detachable (11) running through the side walls of the housing (8) and which in turn is selectively intern by one or several holes (12) existing in said intermediate zone (10) of the lever.

This lever (9), at its opposite end to the connecting rod (7), joins in turn articulated to a traction arm (13) provided with a pair of clamps or jaws (14) for mooring intermittent rod (15), as will be seen later.

These clamps or jaws (14) configure with the own arm (13) a deformable parallelogram, by union articulated on its four sides, incorporating a crossbar intermediate (16), also articulated particularly visible in the Figure 4, so that when the cam or eccentric (3) fraction of the connecting rod (7) and this fraction in turn and through the lever (9) of the arm (13), the jaws (14) are closed on the rod (15) and the consequent drag of the latter, while in the other half-cycle of the eccentric cam (3), is say when it pushes the connecting rod (7), the displacement in direction opposite of the arm (13) causes deformation of the clamps gag in the sense of openness, so that the latter are released of the rod and, keeping the latter temporarily stable, the jaws move along the rod to then tie it up again, but at a point closer to the rake proper that finishes the rod.

It is achieved in this way in each complete turn of the eccentric cam (3), a clamp of the clamps or jaws of the rod, a traction on the latter, a release of the clamps, a displacement of the latter with respect to the rod, and a again tighten the clamps on the rod to repeat the cycle of I work until the approach to the boat. Parallel ropes or auxiliary networks are also dragged by the hauler (4).
