    Abstract

    This summary of the invention refers to the development of a ramp (flexible front guard) that is mounted to a cutting platform to prevent grain loss and dirt from entering the conveyor, consisting of a flexible material sheet (1), capable of being curved (2) near the cutting blade area (3) of a cutting platform (4), containing an inclined portion (8) and another curved portion (5) near the conveyor (6).

    Claims

    1. FLEXIBLE FRONT RAMP FOR RIGID AND FLEXIBLE CUTTING PLATFORM, characterized by consisting of a flexible material sheet (1), capable of being curved (2) near the cutting system area (3) of a cutting platform (4), having an inclined portion (8) and another curved portion (5) near the conveyor (6).

    2. FLEXIBLE FRONT RAMP, according to claim 1 and characterized by having the flexible material sheet (1) attached to the bar/ruler (7) of the cutting system (3) of a cutting platform (4), by means of fastening elements or plates (16), so that these plates (16) fasten an edge (9) of said flexible sheet (1), at the part that can be curved (2), so that the inclined part of the flexible material sheet (1) forms said ramp (8) for transporting the crop material to the conveyor (6).

    3. FLEXIBLE FRONT RAMP, according to claim 1 and characterized by having the curved part (5) in the flexible material sheet (1) form a flap (10) following the ramp (8), where said flap (10) advances over the conveyor (6).

    4. FLEXIBLE FRONT RAMP, according to claim 1 and characterized by the possibility of having the flexible material sheet (1) articulated/hinged at the fastening elements (16), so that the ramp section (8) and the flap (10) can be raised and lowered, exposing the inner part the conveyor (6).

    5. FLEXIBLE FRONT RAMP, according to claim 1 and characterized by having the flexible material sheet (1) made up of a single piece (11), i.e., said flexible material sheet (1) extends over the entire cutting platform (4), even covering the central conveyor (12)

    6. FLEXIBLE FRONT RAMP, according to claim 5 and characterized by the flexible material sheet having other construction options, being divided into more sheets (13 and 14), covering or not (15) the central conveyor (12).

    7. FLEXIBLE FRONT RAMP, according to claim 5 and characterized by the entire flexible material ramp (11) or each of its parts (13 and 14) being able to be attached by means of fastening elements or plates (16), where said plates (16) have holes (17) for receiving screws to fasten said plates to the cutting platform (4), where each of these plates (16) contains claws (18) that grip into the ramp (11) or ramps (13 and 14) so as to keep them in place.

    8. FLEXIBLE FRONT RAMP, according to claim 7 and characterized by the plates (16) having claws (18) that grip into the ramp (11) or ramps (13 and 14).

    Description

    [0020] In this case we have:

    [0021] FIG. 1 shows a cross-section of a cutting platform, where the position of the ramp can be seen;

    [0022] FIG. 2 shows a perspective view of a segment of the cutting platform, to which the flexible ramp is mounted;

    [0023] FIG. 3 shows a perspective view of a cutting platform, where the flexible ramp is mounted along the entire length of the platform;

    [0024] FIG. 4 shows a perspective view of a cutting platform, where two flexible ramps are mounted, one on each side of the platform;

    [0025] FIG. 5 shows a detail of a cutting platform, where the flexible ramp is attached to the platform by fastening elements.

    [0026] FIG. 6 shows a perspective view of one of these fastening elements.

    [0027] A preferred embodiment of the invention comprises a sheet made of flexible material (1), capable of being curved (2) near the cutting system area (3) of a cutting platform (4), containing an inclined portion (8) and another curved portion (5) near the conveyor (6).

    [0028] The flexible material sheet (1) is attached to the bar/ruler (7) of the cutting system (3) of a cutting platform (4), by means of fastening elements or plates (16), so that these plates (16) fasten an edge (9) of said flexible sheet (1), at the part that can be curved (2), so that the inclined part of the flexible material sheet (1) forms said ramp (8) for transporting the crop material to the conveyor (6).

    [0029] The curved part (5) in the flexible material sheet (1) forms a flap (10) following the ramp (8), where said flap (10) advances over the conveyor (6), so as to prevent dirt and grain from falling into the conveyor (6).

    [0030] The flexible material sheet (1) can be articulated/hinged at the fastening elements (16), so that the ramp section (8) and the flap (10) can be raised and lowered, exposing the inner part of the conveyor (6) for cleaning.

    [0031] The flexible material sheet (1) can be made up of a single piece (11), i.e., said flexible material sheet (1) extends over the entire cutting platform (4), even covering the central conveyor (12). Another construction possibility is for the flexible material sheet to be divided into more sheets (13 and 14), covering or not (15) the central conveyor (12).

    [0032] The entire flexible material ramp (11) or each of its parts (13 and 14) can be attached by means of fastening elements or plates (16), where said plates (16) have holes (17) for receiving screws to fasten said plates to the cutting platform (4), where each of these plates (16) contains claws (18) that grip into the ramp (11) or ramps (13 and 14) so as to keep them in place.
