    DESCRIPTION
    Sieving drum and sieve tray comprising said drum
    The present invention relates to a sieving basket of the type comprising a support frame and a mesh structure attached thereto and suitable for rotating mounting on a bucket connectable to the arm of a machine for removing earth, such as a excavator or backhoe.
    In the technical sector in question, the use of sieve cuvettes is known, as described in patent application EP 284 643.
    This patent refers to a sieve tray connected to the arm of an excavator by means of a structure that supports a rotating basket. The basket is provided with a meshed structure of a dimension that allows the passage of only the material of dimensions smaller than a predetermined size. The rotation of the basket is achieved by means of a hydraulic motor driven by the hydraulic circuit of the machine in operation.
    One of the main limits of this sieve tray lies in the fact that it is not possible to regulate the size of the sieved material, since it is linked to the dimensions of the openings in the mesh structure.
    Another example of this type of equipment is described in EP 1 177 839, which refers to a sieve tray in which the sieve drum of the tray is defined by a plurality of replaceable perforated panels.
    Although this solution allows the sieve drum to adapt to different dimensions of the material to be screened, the operations to replace the panels require some time. In fact, it is necessary to remove the panel with holes of a certain dimension and then fit other panels to achieve a variation in the size of the sieved material.
    Another example of screening cuvettes is described in EP2581140 or a crushing bowl having a screening function is described in WO 2006/105864.

    Consequently, the technical problem that constitutes the core of the present invention is to provide a sieve tray that avoids the aforementioned disadvantages of the known technique.
    This problem is solved by the sieve basket according to claim 1.
    Preferred features of the invention are defined in the dependent claims. The present invention has some important advantages. The main advantage consists in the fact that the sieve basket according to the present invention allows the dimensions of the sieved material to be regulated simply and quickly.
    Another advantage refers to the fact that the size of the sieved material can be varied without the need to remove any component.
    According to another aspect, the invention also relates to a sieving basket of the type attachable to a cuvette connectable to a mobile arm of an operating machine comprising a support frame, a first mesh structure connected or connectable to the support frame and which defines at least one perimeter part of the sieve basket in which said first mesh structure has at least one fixing element for detachable fixing of a second mesh structure so that the meshes of the second mesh structure partially intercept the first openings defined by the meshes of said first mesh structure.
    Based on this aspect of the invention, the sieve basket is capable of using the second mesh structure without the need to provide special support frames, which, therefore, can be marketed as a kit or as an accessory.
    Preferably, according to this aspect, said fixing element is defined by a through hole.
    In this way, the presence of the fixing element does not hinder material screening operations.
    In accordance with yet another aspect, the invention also relates to a sieving basket

    With reference initially to Figure 1, a sieve tray according to the present invention is shown as a whole with reference number 100.
    According to a preferred embodiment, the sieve tray 100 comprises a support frame 110 to which a rotation device 102, preferably a hydraulic or electric motor, is connected.
    The tray 100 also comprises a sieve basket 10, shown below in greater detail, which is rotated by means of the rotation device 102.
    The cuvette 100 is also provided with a part 101 for connecting to an arm of an operating machine in a known manner.
    According to a preferred embodiment, the cuvette 100 also comprises a blade portion 104 that connects an edge 105 to collect the material to be screened towards the inlet of the sieve basket 10 which is preferably cylindrical in shape.

    Referring now to Figure 3, the sieve basket 10 comprises a support frame 11, preferably formed by at least two circumferential elements 11a connected by means of radial elements 11b.
    According to a preferred embodiment, the two circumferential elements 11a, together with the radial elements that connect them, identify a cylindrical or perimeter part of the basket 10. Also preferably, a circumferential element 11a is connected to a connection element 12 which allows connect the basket 10 to the rotation device 102 of the cuvette 100 by means of additional radial elements 11b. According to a preferred embodiment, said radial elements define a base part of the basket 10 which, preferably, has a truncated cone shape.
    The basket 10 also comprises a first mesh structure 1 connected to the support frame 11. As shown in the Figures, the mesh structure 1 at least partially defines the perimeter part of the sieve basket 10.
    Preferably, the mesh structure 1 substantially defines the entire perimeter part of the basket 10. In other words, the perimeter part of the basket 10 will be defined by the structure 1 that does not include the support frame 11. In one embodiment, the first Mesh structure also defines the base part of the basket 10.
    Therefore, it is clear that, depending on the dimensions of the meshes of the mesh structure 1, the material of smaller dimensions than the relative openings 1a defined by them can leave the sieve basket 10. The material of dimensions larger than those of the openings 1a instead remain inside the basket, which allows it to be transported to another place.
    Preferably, the first mesh structure 1 is defined by a plurality of removable panels fixed to the support frame 11, preferably in the radial elements 11b, as also shown in Figures 4 and 5.
    According to a preferred embodiment, the removable panels defining the first mesh structure have a shaped edge 14 defining respective recesses 15 in which a fixing device 5 of the removable panels is partially housed.

    In one embodiment, the fixing device is formed by a bolt. Preferably, the fixing device 5 is connected to one of said radial elements 11b to allow the panels to be secured thereto.
    As shown in Figure 5, the shaped edge 14 of a panel, when fixed to the frame 11, is oriented towards a respective shaped edge 14 of an additional panel adjacent thereto.
    In this way, the two facing recesses 15 define a seat capable of accommodating the fixing device 5. In this embodiment, in which the fixing device 5 is a bolt, the bolt rod passes through the seat defined in this way. .
    In this way, the bolt, or other fixing device 5, can be used to contemporaryly fix two adjacent panels, thus allowing a smaller number of fixing devices to be used.
    According to a preferred embodiment, the basket 10 also comprises a support clamp 3 that can be placed on the panels to cover the shaped edges 14 of two adjacent panels.
    Preferably, the fixing devices 5 hold together the radial element 11b, the edge 14 of the panel and the support clamp 3. This solution allows the mesh structure to be fixed efficiently and stably, regardless of the shape of the edge 14.
    The basket 10 according to the present invention also comprises a second mesh structure 2 secured or insurable to the first mesh structure 1.
    To this end, in a preferred embodiment, the first mesh structure 1 has at least one connection device 13 in order to fix the second mesh structure 2 detachably. Preferably, the connection device 13 is defined by a through hole, whereby the second mesh structure is secured to the first by another fixing device 6, also shown in Figure 5, formed by a bolt, for example .
    Alternatively, the second mesh structure 2 can also be fixed to the frame 11 or be
    5
    10
    fifteen

    25

    it can fix both the frame 11 and the first mesh structure 1.
    The second mesh structure 2 is fixed to the first structure 1 in a position such that the meshes of the second partially intercept the first openings 1a defined by the meshes of the first mesh structure 1.
    In one embodiment, the second mesh structure 2 has second openings 2a of a smaller dimension than the first openings 1a.
    In this way, the second mesh structure 2 will cover the first structure during use to protect it from wear.
    As shown in Figure 6, said structure can also be used advantageously in the base part of the sieve basket 10.
    Referring now to Figures 7 to 12, according to a first variation, the basket according to the present invention comprises a connection device 4 designed to fix the second mesh structure 2 in an adjustable way to the first mesh structure 1. This variation differs of the one illustrated above in which the connection device allows the second mesh structure to be fixed in an adjustable manner, while the previous embodiment used a connection device suitable for detachable fixing.
    Preferably, the connection device 4 is suitable to allow relative movement of the second mesh structure 2 in relation to the first mesh structure 1. In one embodiment, the movement occurs between a first operating position in which the meshes of the second mesh structure 2 are superimposed on the meshes of said first mesh structure 1 and a second operating position in which the meshes of the second mesh structure 2 partially intercept the first openings 1a. Alternatively, the first and second mesh structures can be placed in reverse order, with the second structure, that is, the mobile, placed facing the outside of the basket 10. This alternative embodiment is shown in Figures 13 to 18. In this case, for simplicity of illustration, the second mesh structure 2 is shown in only one panel of the first mesh structure 1, it being clear that this configuration can also be adopted for the entire perimeter and / or base part.

    Therefore, it is clear that in the first operating position, the dimension of the sieved material will be determined by that of the first openings 1a, while in the second position, this dimension will be smaller, since the first openings 1a are partially intercepted .
    It will also be noted that in the present embodiment, the openings 1a and 2a have the same dimension, so that in the first operating position these openings coincide, while in the second, the interweave of the meshes of the first and the second structure creates openings capable of allowing the passage of material of smaller dimensions.
    Therefore, it is clear that also in this embodiment, openings 2a of the second mesh structure 2 of smaller dimensions than the openings 1a of the first mesh structure can be provided. Similarly, in the other variations too, the openings 1a and 2a can have the same dimension.
    With reference again to Figures 8 and 7, according to a preferred embodiment, the perimeter part has a cylindrical shape. In this way, the second mesh structure 2 can slide over the first mesh structure 1, remaining thereon, so that the perimeter part is allowed to be made in the form of a single cylindrical shaped panel. More generally, according to a preferred embodiment, the second mesh structure can slide over the first mesh structure in a radial and / or axial direction defined in relation to the basket. In this case, the support frame 11 will be formed by the circumferential elements 11a and, possibly, the radial elements 11b arranged in the base part, as shown in Figure 9. In addition, the circumferential elements 11a can be formed as a single body with the first mesh structure 1.
    Therefore, it is clear that, for these embodiments as well, several panels can be used, fixed to the radial or circumferential elements, as clearly illustrated in Figures 13 to 18.
    The embodiments just described are particularly advantageous because they allow sifting to be adjusted without requiring replacement or removal of any components.
    According to a preferred embodiment, the connection device 4 comprises a guide 41 and a respective slider 42 integrated with the second mesh structure 2 and the first
    5
    10

    25
    1 mesh structure, respectively, or vice versa.
    Preferably, the guide is created by means of a groove formed in the second mesh structure 2, while the slider is defined by means of the rod of a bolt of the connecting device 4.
    According to a preferred embodiment, the guide 41 has a transverse development with respect to an axial direction and a circumferential direction defined by the sieve basket 10. Since, preferably, the openings 1a and 2a have a substantially square shape, both in As in the other embodiments, the movement of the second structure 2 allows to maintain the openings in a regular manner.
    The embodiment described above also allows a panel to be used to define the second mesh structure in the perimeter part, the latter being able to slide as a whole by means of the guide 41.
    Therefore, the invention solves the proposed problem, while providing a plurality of advantages, including the possibility of changing the sieving dimension quickly and efficiently in a rotating system. In particular, it is possible to use a cuvette with a completely meshed structure, thus optimizing sieving operations.
    In addition, it is possible to use common components even for baskets not provided with adjustment of the sieving dimension, thus making the implementation of the present invention easily performed as a kit.
