Description

Fishing net crusher machine.

Object of the invention

The present invention relates to a machine which has been specially designed to crush the networks of fishing, once these, due to their degree of deterioration, result unusable

The object of the invention is to solve the environmental problem that involves the elimination of this type of networks.

Background of the invention

At present it is a problem the get rid of useless fishing nets, given the large dimensions thereof proceeding sometimes to store them, which means occupying a remarkable amount of space, so in most cases these networks old ones are removed at sea, simply throwing them at Water.

Given their non-biodegradable nature, these networks it remains for a long time submerged in water, creating environmental problems, since it involves a permanent risk for the fish, which can easily get caught in them.

Description of the invention

The crushing machine that the invention proposes It has been designed to resolve fully satisfactorily the problem described above, constituting an element of reduced dimensions, which can be used in any installation.

For this and more specifically, the machine which is recommended has a hopper for pouring the nets, that ends on a cutting roller, assisted by a blade which acts on its periphery when the network passes between both elements, producing the crushing of said network.

This cutter roller is driven by a moto-reducer conveniently attached to the chassis of machine.

Tangentially with the cutting roller is place, under it, a cleaning roller mounted with free from turn on the chassis and trained to move axially driven by a cam with which a bearing collaborates, so that this reciprocating movement of the cleaning roller improves the cleaning action thereof on the cutting roller.

The cleaning roller is mounted on the chassis with possibility of positional regulation, in the sense of more or less approximation to the cutting roller, and under these rollers are placed a bag, sack, bucket or similar that collects the crushed networks.

In this way a machine of reduced volumetry and high operational efficiency, capable of crushing the networks up to a sufficient level of fragmentation suitable for disposal as recyclable raw material, low occupancy volumetric compared to what the network implies with its structure initial.

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 part member of that description, a set of drawings where with illustrative and non-limiting nature, what has been represented next:

Figure 1.- Shows, according to a representation schematic side elevation, a network crusher machine fishing carried out in accordance with the purpose of this invention.

Figure 2.- Shows another elevation view side of the same machine, from an observation point 90º out of phase with respect to that of the previous figure, and in which said machine appears partially sectioned to show with greater clarity its lower structure, according to the cut line A-B in Figure 1.

Figure 3.- Shows, finally, a view in machine plant, also partially sectioned, according to the C-D cut line of Figure 1, with the same purpose of showing its interior elements.

Preferred Embodiment of the Invention

In view of the figures outlined you can observe how the machine that is recommended is constituted to starting from a chassis or bench in which sectors are defined, one lower (1), which rises properly with respect to the ground working area of the machine, and a higher one (2) where establish the mechanisms of the same, receiving this sector upper (2) of the chassis, in turn superiorly, to a hopper (3) to through which the material, that is the old fishing nets, access the inside of the machine.

This hopper (3) unloads on a roller cutter (4), mounted transversely on the chassis (2) through of bearings (5), roller whose shaft (6) receives the movement of a moto-reducer (7) conveniently fixed too to the chassis (2) of the machine.

With the cutting roller (4) a blade (8) that obliquely attacks the roller (4) and that is of Adjustable positioning with the contest of a couple of screws (9), especially visible in figure (3).

Under the cutting roller (4) a roller is placed cleaner (10), whose shaft (11) is mounted with freedom of rotation on the chassis (2) through bronze bearings (12), which they are also adjustable positioning, in order to allow the cleaning roller (10) approximates to a greater or lesser extent the cutter roller (4). For this, the bearings (12) rest on two screws (13) that play in complementary nuts (14) duly fixed to the chassis (1) and assisted by locknuts (15)  for positional locking of the bearings (12) once it has been defined the position chosen for the cleaning roller (10).

This cleaning roller (10) is also subjected to a longitudinal reciprocating movement, for which purpose its axis (11) it is topped by one of its ends on a cam (16), provided with a  oblique throat (17) in which a bearing (18) plays, such as it is especially observed in figure 3, so that being said bearing (18) fixed, through an intermediate support (19), to the chassis (2) of the machine, the rotating movement of the cam (16), supplied to it by the dragging effect of the cutter and drive roller (4) on the cleaning roller (10), brings I get the longitudinal and alternative displacement of this Last, which ensures the perfect cleaning of the cutter roller (4).

It only remains to point out that in the area of union between the lower sector (1) of the chassis and the upper sector (2) thereof, fixing means are established for a bag (20) or any other similar container, suitable for receiving waste generated by the crushing machine.

Claims (5)

1. Fishing net crusher machine, characterized by being constituted from a chassis on which a receiving hopper of the grinding nets rests, which ends on a cutting roller assisted by a blade, placing a roller under said cutting roller cleaner for the aforementioned cutter roller, and this assembly being sufficiently raised so that a bag or any other collector receptacle of the crushed networks is placed under it. 2. Fishing net crusher machine according to claim 1, characterized in that the axis of the cutting roller is mounted with freedom of rotation on the chassis through bearings, and receives a rotating movement supplied by a motor-reducer. 3. Fishing net crusher machine, according to previous claims, characterized in that the blade, which acts obliquely on the cutting roller, is of adjustable positioning with the collaboration of a pair of screws that allow maintaining the position of proper proximity of said
blade with respect to the cutting roller. 4. Fishing net crusher machine, according to previous claims, characterized in that the axis of the cleaning roller is mounted with freedom of rotation on the chassis, through bearings, said roller being dragged by the cutting roller, with which it contacts tangentially, having provided that at one end of the axis of said cleaning roller a cam is established, with an oblique throat, in which a bearing provided with a fixed support to the chassis plays, so that the assembly constituted by the cam and the bearing they cause an axial and alternative movement in the cleaning roller. 5. Fishing net crusher machine according to claim 4, characterized in that the bearings on which the axis of the cleaning roller rests are mounted on the chassis with the collaboration of positional adjustment means, consisting of screws that play on nuts fixed to the chassis , so that these screws allow to regulate the height position of the bearings, and through the latter the degree of proximity of the cleaning roller to the cutting roller.
