Device for incorporating and distributing sand and aggregate in synthetic grass

A device designed to improve the incorporation and distribution, by mixing, in an artificial lawn, of sand used to weigh it down as well as rubbery granules used to improve its flexibility, the aforementioned artificial lawn being comprised of supple blades joined to a carpet;

• characterized in that it comprises, supported by a common frame and acting successively and in cooperation:
• a) a first means designed to improve, with each passage, by lifting the blades, the penetration of sand and granules between the blades of the lawn as closely possible to the carpet, the aforementioned means comprised a row of prongs joined to a transverse support itself joined to a means configured to angularly preadjust the aforementioned support according to multiple adjustment positions so as to increase the pressure of the prongs on the lawn as the advancement of the spreading progresses which is effected by successive passages
• b) a second means designed to improve, at each passage, the distribution, on the aforementioned lawn, of the sand and granules remaining on the surface after the passage of the first means, the aforementioned second means being comprised a row of brushes comprising:
• two contiguous central brushes, positioned V-shaped, adapted for obliquely displacing, in the direction of the free ends of the aforementioned brushes, a portion of the sand and granules;
• two lateral brushes, each positioned on each side of the central brushes, parallel to the one that it is opposing, adapted for obliquely displacing in the direction of the exterior ends of the aforementioned brushes, a portion of the sand and granules.
