Definitions

  • the present invention describes a platform line for harvesting corn and the like.

  • the platform has puller rollers with different diameters that favor the removal of a greater volume of leaves and stalks around the corn cobs, thus reducing the overload of the combine threshing system and fuel consumption, in addition to increasing the yield of harvested area.
  • This new constructive form applied to the corn harvesting platform promotes a significant weight reduction, due to the possibility of manufacturing platforms with a much larger number of lines and greater width, increasing its yield.
  • This system reduces the amount of components per line which allows an increase in the harvester's yield due to increasing the number of lines next to the platform. Despite the greater number of lines, the equipment presents a significant reduction in its weight due to the reduction of components, reducing fuel consumption and minimizing soil compaction.
  • the corn platform uses a set of transmission boxes with puller rollers, double chains and individual structures for each corn line.
  • corn platforms are usually limited to around 26 lines, with a width of 45 cm per line, around 12 meters of useful harvesting area and weighing around 5 tons. This weight requires a very strong harvester structure, which ends up generating soil compaction due to the pressure exerted by the machine and possibly breaking the structure of the harvesting machines.
  • the transmission boxes on the market use seven to eleven gears, or even more in imported models, which generates a high manufacturing cost because the gears directly influence the final price of the transmission box, and how much the more gears, the higher the cost of making the case.
  • the present inventor seeking to improve the efficiency of this equipment, developed a new construction that allows to reduce the number of components of the line in order to increase the harvesting efficiency, as it reduces the weight of each line, to approximately 50-60 Kg, allowing a greater number of lines to be arranged per platform, considerably increasing the harvesting width, which reduces fuel consumption and reduces soil compaction.

Abstract

La présente invention a pour objet une ligne de plateforme pour récolte de maïs et analogues, comprenant une ligne de plateforme avec boîte de transmission (30) présentant un nombre réduit d'engrenages et possédant une courroie (11) à godets (11) déplaçant une ou plusieurs rosettes (22) dotées de doigts (221) de traction, permettant le guidage et le chargement des épis vers l'intérieur de la récolteuse, ce qui réduit la quantité de composants. La plateforme possède des rouleaux de traction (15) et (23) de diamètres différents qui favorisent la suppression d'un grand volume de feuilles et de tiges autour des épis de maïs étant donné que le petit rouleau reste au voisinage des plaques épanouilleuses, réduisant ainsi la surcharge du système de battage des récolteuses ainsi que la consommation de carburant, outre le fait d'augmenter le rendement de la surface de récolte.
