Definitions

  • the present patent relates to the sugarcane harvesting machinery sector, with an approach in the management of the sugarcane cutting system, aiming to increase the number of mechanized crops in the field, and conferring to the producer greater gains for the conservation of the natural crop, as well as as, economy and speed in the sugar cane cutting system and its maintenance in a rational and correct way.
  • Sugarcane harvesting machines are widely known in the current art. In these machines, one of the most relevant parts is in the arrangement and utilization of the laminate knives disposed in the cutting discs forming the cutting assemblies, flange coupled in the lower front area of the harvesters.
  • the cane cutting operating system on the harvester machine is made up of a pair of disks that are horizontally interposed as close to the ground as possible and rotated in opposite directions to cut and pull the cane into the machine. , occurring in this continuous cutting process, the loss of spinning of the laminate knives and their arrangement in the discs, facilitates the removal of the knuckle by the impact suffered, and thus greatly impairing the reproduction of the cane, once the knuckle extraction will no longer occur. germination and thus the decrease in production in the planted area.
  • Conventional cane harvesting machines are equipped with clamping discs for laminated cutting knives that mechanically cut the cane.
  • Such knives are manufactured made of carbon steel and arranged radially to the disc longitudinally.
  • the disc has central bolt holes for fixing the cutting assembly to the flange, as well as the laminated cutting knife has enough structurally longitudinally rectilinear holes for greater adjustment flexibility for reuse.
  • the laminated knife can be displaced radially to the disc, because, due to operational wear, there is a need for frequent adjustments in relation to the sharp part of the blade. It is maintained by loosening the screws and retightening them every three to four hours of operation, totaling an average of 12 hours of service life for each knife, and as a result, the harvester will be shut down. damage by downtime of cutting equipment.
  • the proposed innovation consists of a cutting assembly, consisting basically of three discs of sturdy material and laminated cutting knives, fixed and regulated to the cutting assembly by means of gears, drag rack and locking device of the laminate knives, the which are juxtaposed and equidistant at the ends of the intermediate disc.
  • the cutting assembly provides a practical and robust system in which the laminate cutting knives arranged substantially tangentially to the central hole in the intermediate disc are fixed and locked by snapping into flexible cavities disposed in the structure of said disc, and moved by means of a drag adjustment system through rack-like gears provided with a pinch or clamping nozzle through the external holes disposed on the sides of the side discs, without the need to disassemble the assembly.

  • Laminate knives are fixed tangentially to the central hole and can vary from 0 to 180 °, with the cutting edge positioned forward or backward (positive or negatively) according to the proposed adjustment.
  • the three discs (bottom, middle, and top) mold into a cutting unit to form an assembly in which the laminated cutting knives are inserted and firmly secured.
  • the cutting assembly object of the present patent, besides providing better utilization of the laminated knives, introduces the innovation of their adjustment by means of drag and lock gears, avoiding the knifes release due to the inherent rotation and shaking of the machine. to the harvest work.
  • the present cutting assembly offers a substantial differential over those known in the current art. It has a cheaper final cost, provides less material waste, allows better waste disposal and generally provides better use of harvested sugarcane due to the fact that it offers a smoother and more homogeneous cut. In addition, it allows the exchange of any of its knives in a simplified way, gives flexibility in relation to the number of knives used, better utilization of the laminated knives and, mainly, adds ease of adjustment and fixation of the laminate cutting knives in the respective discs.
  • a first objective of the application is to optimize the sugarcane harvest, proposing a more efficient cutting system and the maintenance of the cultivated area avoiding the extraction of the brass knuckles and thus seeking greater use and production of sugarcane.
  • a second purpose of the application is to Facilitate the adjustment of the position of the laminate knives in relation to the intermediate disc through the use of a rack system, as well as the maintenance of the cutting assembly that allows less time for adjustment and fixing in the assembly.

Abstract

L'innovation proposée consiste en un ensemble de coupe, constitué essentiellement par trois disques de matériau résistant et des lames de coupe fixées et réglées sur l'ensemble de coupe au moyen d'engrenages de type crémaillère d'entraînement et dispositif de blocage des lames de coupe, lesquelles sont juxtaposées et équidistantes aux extrémités du disque intermédiaire. L'ensemble de coupe permet d'obtenir un système pratique et robuste, dans lequel les lames de coupe disposées de manière sensiblement tangentielle par rapport à l'orifice central sur le disque intermédiaire, sont fixées et bloquées par emboîtement dans des cavités souples situées dans la structure dudit disque, et mises en mouvement au moyen d'un système de réglage par entraînement à l'aide d'engrenages de type crémaillère, qui présentent une embouchure de serrage ou libération par clé à douille, via les orifices extérieurs situés sur les côtés des disques latéraux, sans qu'il soit nécessaire de démonter l'ensemble. Le disque inférieur et le disque supérieur sont égaux en taille et en forme. Le disque intermédiaire possède également une taille similaire, mais se différencie des autres disques en ce qu'il est spécialement fabriqué avec matériau plus noble (résistance à la fatigue, effet ressort, résistance à l'impact et à l'usure) en vue d'une adaptation aux lames de coupe et aux engrenages d'entraînement et de blocage.
