    Threshing mechanism (1), with combs (6.1, 6.2) threshing on the surface of the concave (2) and on the bars (5) or teeth of the threshing cylinder (3), where the latter have a first section ( 7) attached to the bar (5) and a second section (8) that is separated from it, comprising a mesh (9) between combs (6.1) of the concave (2), and at least a portion of the combs (6.2) ) of the threshing drum (3) comprise a first friction piece (10) on the outer surface of the second section (8), and, at least a part of the combs (6.1) of the concave (2), comprise on the surface outside thereof, a second friction piece (11), where the first and second friction piece (10, 11) of the combs (6.1, 6.2) comprise notches (12) on their outer surface.

    Figure 2.- Shows a schematic view of the comb profile installed on the threshing cylinder for a preferred embodiment of the invention.
    Figure 3.- Shows a schematic view of the comb profile installed on the concave 5 for a preferred embodiment of the invention.
    Detailed description of a preferred embodiment of the invention
    In view of the figures provided, it can be seen how in an embodiment
    10 preferred of the invention, the threshing mechanism 1, which is proposed herein, is oriented to the harvesting of Pratenses seeds and is part of a harvesting machine for seed collection.
    The threshing mechanism 1, as shown in Figure 1 comprises a concave 2, a
    15 threshing cylinder 3 with a central axis 4 of rotation transverse to the direction of advance of the machine that has bars 5 on its surface and, threshing combs 6.1 held along its entire length and spaced apart on the surface of the concave 2 and some combs
    6.2 of threshing on the bars 5 of the threshing cylinder 3, which have a first section 7 attached to the bar 5 and a second section 8 which extends away from it.
    As can be seen in Figure 1, threshing mechanism 1 further comprises a mesh 9 located in the spaces between combs 6.1 of the concave. This mesh 9 has a mesh light such that it allows the seeds to pass but not the rest of the vegetable mass.
    25 In Figure 1 it is shown, in turn, that in this threshing mechanism 1, at least a part of the combs 6.2 disposed in the threshing cylinder 3 comprise a first friction piece 10 coupled thereto, on the outer surface of the second section 8, oriented towards the concave 2 in the position closest to it of the
    30 threshing cylinder rotation 3. In this preferred embodiment of the invention, half of the combs 6.2 of the threshing cylinder 3 have the first friction piece 10 and are arranged alternately with the combs 6.2 which do not have said first friction piece 10.
    35 In addition, said second section 8 has an inclination such that in the position closest to a comb 6.1 of the concave 2 both are in a parallel position.

    Likewise, at least a part of the combs 6.1 arranged on the surface of the concave 2, comprise on the outer surface thereof, oriented towards the threshing cylinder 3, a second friction piece 11 coupled thereto, where the first 10 and the second friction piece 11 of the combs 6.1 comprise notches 12 on its outer surface. In this preferred embodiment of the invention, all combs
    6.1 of the concave 3 have said second friction piece 11.
    In this preferred embodiment of the invention, the notches 12 existing in all the first friction pieces 10 of the combs 6.2 of the threshing cylinder 3 have a rectangular shape, as shown in Figure 2, while, as can be seen in Figure 3, the notches 12 existing in all the second friction pieces 11 of the combs 6.1 of the concave 2 are triangular in shape.
    The combs 6.1 must be sufficiently spaced in the concave 2, to increase the threshing yield and allow the separation of the seeds from the rest of the plant in the threshing process.
    In this preferred embodiment of the invention it has been considered that the notches 12 in all the first friction pieces 10 are rectangular and in all the second friction pieces 11 are triangular, but in another embodiment it could be the opposite or that both the first and the second friction pieces 10, 11 have the same type of notch 12 or even that some of the first friction pieces 10 have a rectangular and the other triangular type 12, and the same occurs with the second parts friction 11.
    Likewise, and as shown in Figure 1, in this preferred embodiment of the invention, the threshing mechanism comprises a side closing device of the threshing cylinder, formed by side closing walls 13 located between each two bars. 5 consecutive threshing cylinder 3, parallel to the central axis 4 of rotation thereof. In this way, the plant material being threshed cannot be introduced inside and the threshing process performance is increased.
    The described embodiment constitutes only an example of the present invention, therefore, the specific details, terms and phrases used herein are not to be considered as limiting, but are only to be understood as a basis for the claims and as a representative basis that provides a description
