Definitions

  • the present invention refers to agricultural equipment in general and, more specifically, to a sweeping platform for collecting seeds from the ground for use in connection with a grain harvester, specifically designed for collecting from the ground, in the last steps of harvesting, the seeds used in the formation of pastures.
  • Harvesters are devices used in agriculture for separating fruit and grains from their supporting branches or the like, and for collecting and packing these grains after they have been duly cleaned and separated.
  • the seeds are devided into seed collected from the raceme ana seeds collected from the ground and between these two groups of seeds - collected from the raceme and from the ground - the greatest demand always falls on the seeds collected from the ground, for they show a germination index of approximately 85 s versus an index of approximately 40* of the seeds collected from the raceme, this significative difference being due to the high degree of matureness of the seeds collected from the ground when compared to that of the seeds collected from the raceme.
  • hoses are manually conveyed by operators while the harvester is displaced, in such a way that the seeds are drawn to the interior of the machine by means of hoses and then fall onto a vibrating sieve that separates them from any impurities.
  • a serious drawback in the suction type harvester described above is that it cannot be provided with means for continuously eliminating dust and residues drawn together with the seeds, for the presence of operators around the machine makes it impossible to provide means for the continuous elimination of dust and residues drawn together with the seeds, since this would generate a highly deleterious environment for the operators.
  • the bin designed for this purpose within the machine becomes completely filled after suction has been applied to the ground for a few meters, what requires an interruption in the equipment operation until these impurities are removed therefrom.
  • a third drawback of the suction type harvester described above is that usually the seed is stuck to the ground, what requires an additional operation for sweeping the ground before the machine is moved.
  • a harvester for collecting seeds from the ground that solves the above mentioned problems of the suction type harvester of the prior art.
  • a sweeping type harvesting machine for collecting seeds from the ground that continuously removes dust and residues drawn together with the seeds without generating a deleterious environment for the operators, thus eliminating the need for a frequent interruption in the operation of the equipment for removing said impurities.
  • the harvester disclosed in this utility model patent application does not require a previous preparation of the ground before its passage, thus eliminating the need for an extensive manpower.
  • Another advantage of the harvester according to the above mentioned utility model patent application is that it is provided with means for sweeping the ground where the seed is usually retained, thus eliminating the need for an additional sweeping operation of the ground before the machine is moved.
  • a sweeping type harvester for collecting seeds from the ground wherein a rotating brush mounted on a front end of tne machine sweeps the surface of the groun ⁇ in sucn a way that the seeds and impurities are directed to a front baffle means where a strong air current formed by the brush rotating at high speed (450 rpm) causes a venturi effect that draws the seeds and impurities to a selection compartment provided with vibrating sieves where the seeds are separated from the impurities.
  • a sweeping type harvester for collecting seeds from the ground that solves the above mentioned problems of the harvesters of the prior art.
  • a sweeping type harvester for collecting seeds from the ground that comcnses s brush rotationally mounted on an axle provided at the front en ⁇ of the machine, said axle being positioned in relation to the around in sucr a way that it folds the brush against the qround when it is rotated;

  • a grain harvester not m use may be easily incorporated for collecting seeds from the ground, for it is already provided with a mecnanism for separating the seeds from the dust and impurities, and this is a cheaper solution for the planter than buying a new seed harvester.
