    [0002] Brush structure for sweeping machine
    [0003] The object of the present invention is a lightweight and easily assembled structure for brushes, and particularly for sweeping machine brushes.
    [0005] State of the art
    [0007] On construction sites, sweeping machines are used to collect waste such as dust or gravel generated during milling tasks to lift pavements in poor condition, in order to facilitate the work on site and facilitate the adherence of the layers applied later, or as a finishing work for the work prior to painting the pavement.
    [0009] Document ES2244256A1 describes a scoop-sweeper tool for construction sites whose function is to sweep through a roller or brush with filaments. The roller or brush is formed by a core or shaft that has keys and on which a set of rings keyed to said core are mounted. Each of said rings comprises a set of perimeter holes into which a set of filaments are inserted, usually of steel cable, so that the two ends of each filament exit through two adjacent holes, leaving the bent part of the filament in the inside the hoop. In said document it can also be seen how the shaft or core is a solid core.
    [0011] The present invention provides a sweeping machine brush structure that allows for a simpler installation, and therefore reducing assembly time and cost, of the sweeping filaments on each of the hoops. Additionally, the present invention has a configuration that allows to lighten the brush shaft of the sweeping machine
    [0013] Explanation of the invention
    [0015] The structure for the sweeping machine brush object of the present invention is made up of a shaft and a set of rings, said rings carrying the sweeping filaments. Each one of the rings is made up of two pieces that are coupled together and form the ring for the sweeping machine brush. Each of the pieces that make up the ring to A sweeping machine brush is called a "semi-ring" (each of the semi-rings consists of a ring capable of being coupled to the other semi-ring to form the ring for the sweeping machine brush object of the present invention).
    [0017] Each of the half rings has an inner face, which is the face for coupling to the other half ring to form the ring for the sweeping machine brush object of the present invention, and an outer face.
    [0019] The inner face of each of the half-rings that make up the brush ring comprises means for fixing the other half-ring.According to one embodiment, said fixing means consist of a set of bolts arranged on the inside face of a half-ring, and a set of housings corresponding to said bolts on the inside face of the other half-ring, so that the bolts are inserted into the housings and the inside faces of the two half-rings are joined, being in contact with each other. According to one embodiment option, each of the inner faces of each half-shell comprises both bolts and housings for bolts arranged on the inside face of the other half-shell.
    [0021] The inner face of each semi-hem further comprises a set of "U" shaped recesses, so that the ends of the arms of said recesses extend up to the perimeter edge of each semi-hem. When the half-beams are coupled to each other, the recesses of both half-beams coincide, so that once joined they form a “U” -shaped housing with two outlet holes on the perimeter edge. In this way, and prior to coupling both half-rings to form the ring for the sweeping machine brush, a sweeping filament, normally made of steel cable, is arranged in each of the recesses of a half-ring, the ends of each filament extending radially. towards the outside of the semi-ring; and once the filaments have been arranged in the respective housings of the semi-ring, the other semi-ring is coupled, leaving the filaments embedded in each housing.
    [0023] According to one embodiment option, the ring further comprises on its outer faces (that is, on the outer face of each of the half rings) a set of coupling means to the adjacent ring. The purpose of these means of coupling a ring with the adjacent ring is that the motive power is transmitted from one ring to another tangentially, avoiding that the shaft is the element that transmits all the motive power to each one of the rings, and, therefore, making it possible to lighten said axis, and thus reduce the weight of the entire brush structure for the sweeping machine.
    [0024] While a solid shaft can be used, and transmitting the driving power through the key, preferably the shaft is made up of tube fragments, joined through one or more linear elements. According to one embodiment, the tube fragments are joined by one or more keys corresponding to the keyways of the rings.
    [0026] Brief description of the drawings
    [0028] 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 a practical embodiment thereof, a set of figures is attached as an integral part of said description. where, with an illustrative and non-limiting nature, the following has been represented:
    [0030] Figure 1 shows a perspective view of a pair of rings of the sweeping machine brush structure coupled to each other, according to an embodiment of the present invention.
    [0032] Figure 2 shows in perspective a ring of the sweeping machine brush structure, in which the two portions that form the ring are uncoupled, according to an embodiment of the present invention.
    [0034] Figure 3 shows a perspective view of a pair of rings of the sweeping machine brush structure coupled to each other, one of the rings comprising a set of sweeping filaments, according to an embodiment of the present invention.
    [0036] Figure 4 shows a detail of the arrangement of the filaments in one of the recesses made in each of the rings of the sweeping machine brush structure, according to an embodiment of the present invention.
    [0038] Figure 5 shows a perspective view of the shaft of the sweeping machine brush structure, according to an embodiment of the present invention.
    [0039] Description of the preferred embodiments of the invention
    [0040] In view of the aforementioned figures, and in accordance with the numbering adopted, an example of a preferred embodiment of the invention can be seen in them, which comprises the parts and elements that are indicated and described in detail below.
    [0042] The structure for the sweeping machine brush object of the present invention is formed by a shaft (11) and by a set of rings (1), said rings (1) carrying the sweeping filaments (10).
    [0044] Thus, as can be seen in Figures 1 to 4, each of the structure's rings is made up of two semi-rings (2). Each of the semi-rims (2) comprises on its inner face a set of recesses (5) in the shape of a "U", so that the ends of the arms of said recesses (5) extend up to the perimeter edge of each semi-rim. (2). When the half-rings (2) are coupled together, the recesses (5) of both half-rings are coincident, so that once joined they form a "U" -shaped housing with two outlet holes (6) in the perimeter edge. In this way, as can be seen particularly in Figure 4, and prior to coupling both half rings (2) to form the ring (1), a scanning filament (10) is arranged in each of the recesses (5) of one of the half-rings, the ends of each filament (10) extending radially outward from the half-ring (2); and once the filaments (10) are arranged in the respective housings of the half-ring, the other half-ring (2) is coupled, leaving the filaments (10) fitted in each housing.
    [0046] Additionally, each of the half-rings (2) comprises on the inner face means for fixing the other half-ring (2). In the embodiment shown, said fixing means consist of a set of bolts (3) arranged on the inner faces of the two half rings (2) that form the ring (1), and a set of housings (4) corresponding to said bolts (3) arranged on the inside faces of the two half rings (2). In the embodiment shown, the bolts (3) and the housings (4) are alternately arranged in the gap formed between the arms of each of the recesses (5) in each half-ring (2).
    [0048] The ring (1) further comprises on its outer faces (that is, on the outer face of each of the half rings (2)) a set of coupling means to the adjacent ring. These coupling means consist of a set of protruding portions (7), that is to say that protrude on the outer face of the ring (1), which are inserted into a set of second recesses (8) arranged on the outer face of the adjacent ring (1). Preferably, each of the outer faces of each ring comprises a set of projecting portions (7) and second recesses (8) arranged alternately.
    [0050] Figure 5 shows a possible embodiment of the shaft (11) of the structure for the sweeping machine brush. The shaft (11) is formed by a set of tube fragments (12) joined together by means of a set of keys (13) corresponding to keyways (9) made in the central hole of each ring (1).
