 FISHING NETWORK MACHINE

D E S C R I P C I Ó N

OBJECT OF THE INVENTION

The present invention relates to a machine that has been specially designed to crush fishing nets, once these, due to their degree of deterioration, are unusable.

The object of the invention is to solve the environmental problem of eliminating this type of networks.

BACKGROUND OF THE INVENTION

Nowadays, it is a problem to get rid of useless fishing nets, given the large dimensions of the same, sometimes proceeding to store them, which implies the occupation of a considerable amount of space, so in most cases these Old networks are removed at sea, simply throwing them into the water.

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

The crushing machine that the invention proposes has been conceived to solve in a fully satisfactory way the problem previously exposed, constituting an element of small dimensions, which can be used in any installation.

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

This cutting roller is driven by a motor reducer conveniently fixed to the machine chassis.

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

The cleaning roller is mounted on the chassis with the possibility of positional adjustment, in the sense of greater or lesser approximation to the cutter roller, and under these rollers is a bag, bag, bucket or similar that collects the crushed networks.

In this way a reduced machine is achieved Volumetry and high operational efficiency, capable of crushing the networks to a sufficient level of fragmentation and suitable for disposal as a recyclable raw material, of low volumetric occupancy compared to that assumed by the network with its initial structure.

DESCRIPTION OF THE DRAWINGS

To complement the description that is being made and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical implementation thereof, a set of drawings is attached as an integral part of said description. In an illustrative and non-limiting manner, the following has been represented:

Figure 1 shows, according to a schematic representation in side elevation, a fishing net crusher machine made in accordance with the object of the present invention.

Figure 2.- Shows another side elevation view of the same machine, from an observation point offset 90 ° from that of the previous figure, and in which said machine appears partially sectioned to show its lower structure more clearly, according to the cut line AB of Figure 1.

Figure 3.- Shows, finally, a plan view of the machine, also partially sectioned, according to the CD cutting line of Figure 1, with the same purpose of showing its interior elements. PREFERRED EMBODIMENT OF THE INVENTION

In view of the aforementioned figures, it can be seen how the machine that is recommended is constituted from a chassis or bench in which sectors are defined, a lower one (1), which adequately elevates the work area of the machine, and another superior (2) where the mechanisms of the same are established, receiving this upper sector (2) of the chassis, in turn superiorly, to a hopper (3) through which the material, that is the networks old fishing, access the inside of the machine.

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

With the cutting roller (4) a knife (8) collaborates that attacks the roller (4) obliquely and that is of adjustable positioning with the contest of a pair of screws (9), especially visible in the figure (3).

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

This cleaning roller (10) is also subjected to a longitudinal reciprocating movement, for which purpose its axis (11) is topped by one of its ends on a cam (16), provided with an oblique throat (17) in which it plays a bearing (18), as observed especially in Figure 3, so that when said bearing (18) is 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 cutting and driving roller (4) on the cleaning roller (10), brings with it the longitudinal and alternative displacement of the latter, which ensures the perfect cleaning of the cutting roller (4).

It only remains to note finally that in the junction area 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 the waste generated by the crushing machine.

Claims

R E I V I N D I C A C I O N E S I .- Machine crusher ^to fishing nets, characterized by being formed from a chassis on which rests a receiving hopper networks crushed, which opens onto a roller cutter assisted by a blade, being placed under said cutter roll a cleaning roller for said cutting 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 .- Machine crusher fishing nets, according ^to claim I, wherein the axis of the cutter roll is mounted with freedom of rotation on the frame via bearings, and receives a rotational movement provided by a motor reducer. 3 .- Machine crusher fishing nets, according to previous claims, characterized in that the blade, acting obliquely on the cutting roller is adjustable positioning with the collaboration of a pair of screws that keep the proper position of said proximity blade with respect to the cutting roller. 4 .- Machine crusher fishing nets, according to previous claims, characterized in that the cleaning roller shaft is mounted with freedom of rotation on the chassis, through bearings, said driven roller by the cutting roller, with which contact tangentially, having provided that at one of the ends of the axis of said cleaning roller a cam is established, with an oblique throat, in which a bearing plays provided with a fixed support to the chassis, so that the assembly constituted by the cam and the bearing cause an axial and alternative movement in the cleaning roller. 5 .- Machine crusher fishing nets, according ^to claim 4, characterized in that the bearings on which rests the cleaning roller shaft are mounted on the chassis in cooperation with position regulation means, consisting of screws nuts playing in 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.
