Definitions

  • the invention relates to a self-propelled agricultural harvester with a cooler and a perforated radiator basket through which a cooling-air cleaning device for removing dirt particles contained in the intake cooling air and adhering to the radiator basket is arranged.
  • a cleaning device for rotating cooling air filter for removing the adhering to the front and / or shell side dirt by lying in the interior of the rotating cooling air filter rotating brushes that penetrate the air inlet openings of the radiator basket from the inside out and remove in this way the resulting outside of the radiator basket impurities.
  • the cleaning is supported by an outside of the radiator basket, located in the brushes, suction fan, which absorbs the falling dirt particles.
  • a cleaning device with two brushes outside the radiator basket is off US 2002 0 088 208 known.
  • the invention is therefore the object of developing a cooling air purification device of the type mentioned and associated brush and suction so that the disadvantages of the prior art described are avoided and optimal protection of the radiator is achieved.
  • Outer support of the brushes removes the removed crop particles directly from the cooler basket without the possibility of penetrating the interior of the cooler basket, thereby allowing unrestricted performance of the downstream members, e.g. the cooler is ensured.
  • the crop parts are detected directly by the brushes, so that a setting of the parts due to the almost simultaneous processing by the brushes is not possible.
  • the number of brushes can be reduced to a brush. This is especially true for low dirt particles and lowde Kunststoffbedanf, since the radiator basket then requires no increased cleaning. As a result, corresponding costs are saved.
  • a conical brush is arranged, which becomes narrower towards the center of the radiator basket.
  • the brush adapts to the different rotational speed, since this is lower at the center of the radiator basket and increases towards the outside.
  • a further cylindrical brush is arranged on the outer shell side of the radiator basket. This brush performs the same function as the brush mounted on the front and helps to clean the radiator basket over its entire outer surface.
  • Each of the brushes consists of bristles, which first ablate the dust and Erntegutpumblen incurred on the surface of the forehead and shell side.
  • each of the brushes is adapted to penetrate into the openings of the radiator basket, so that clogging of the radiator basket perforation is prevented.
  • the turbulences occurring here of the removed dirt are detected by each of the brushes surrounding and opened to the cooler basket suction device.
  • This suction device is a unit and leads the dirt picked up via a suction hose from the radiator basket away. As a result, on the one hand ensures a clean cooling air and on the other hand, the dirt particles carried away on a short and deflection poor way.
  • the cleaning effect of the radiator basket can also be further increased by providing alternatively or cumulatively for supporting the suction, a compressed air nozzle arranged in the interior of the radiator basket in the immediate area of the brushes, which can be actuated continuously or in case of need in order to open the radiator basket openings by the compressed air flow generated thereby kept clear.
  • the in the FIG. 1 shown agricultural harvester 1 is designed as a self-propelled harvester 2.
  • the combine harvester is preceded by a Erntegutage réelle 3, cut through the crop, not shown, recovered and the agricultural harvester 1 is fed.
  • the agricultural harvesting machine 1 is driven by a drive motor 4 which, by its associated cooler 5 in accordance with Fig. 2 is cooled.
  • the radiator 5 is located immediately behind the radiator basket 6.
  • On the outside of the agricultural harvester 1 is the cooling air cleaning device 7 and this enclosing the air suction 8 whose suction 9 leads to the lower portion of the agricultural harvester 1 to the polluted air from the Transport away cooler basket area.
  • FIG. 2 shows the brush 10 is formed on the end face 11 of the radiator basket 6 conical.
  • Another cylindrically shaped brush 12 is attached to the radial shell side 13.
  • the brushes 10, 12 may be actively or passively driven, rotating in opposite directions 15 to the rotating radiator basket 6 via their brush axes 14.
  • the drive is effected by means of a drive motor 16 which sets a drive belt 17 in motion.
  • This drive belt 17 extends over a mounted on the outer shell side 13 of the cooler basket 6 belt guide 18th
  • This pulley 19 is located at the outer end of the cylindrically shaped brush 12.
  • both the radiator basket 6 and the cylindrical brush 12 are driven.
  • the conical brush 10 is also rotated.
  • the brushes 10, 12 are stationary associated with the radiator basket 6, which in turn rotates 21, Fig. 3 ,
  • radiator basket 6 stationary and the brushes 10,12 can be mounted rotating to the radiator basket 6.
  • the air suction 8 is mounted rotatably and surrounds the individual brushes 10, 12, which is opened to the radiator basket side to directly absorb the dirt adhering and brushed there and transported away by the suction tube 9 of the cooler basket 6.
  • the Fig. 3 shows the sectional view of a radiator basket 6 in front view.
  • the individual bristles 22 of the brushes 10, 12 remove the dirt lying directly on the front 11 and shell side 13 and additionally penetrate the individual perforation holes 23 of the radiator basket 6 during rotation.
  • the brushes 10, 12 consist of individual bristles 22 which are interposed by plastic paddles 24 can.
  • the radiator basket 6 is supported by individual spokes 25 which extend from the support axis 26 located in the center of the radiator basket 6 and are fixedly connected to the inside of the shell side 13 of the radiator basket.
  • This shielding plate 28 is located in the immediate vicinity of the outside of the radiator basket 6 located Windleitkanals 29, the brush 10, 12 and the air extraction device 8 connected thereto and is opposite.
  • the wind guide 29 is connected to the cooling air - cleaning device 7 and includes a narrow and U-shaped part of the shell side 13 of the rotating radiator basket 6 without touching it.
  • the Fig. 4 starting from the center of the radiator basket 6 extends from the support shaft 26 on the support arm 27 along an air line 30, the end of which is connected to a compressed air nozzle 31, which in turn with the shield 28 communicates.
  • the compressed-air nozzle 31 extends almost over the entire depth of the shielding plate 28, which has a slot-shaped opening corresponding to the nozzle outlet opening, so that the compressed air reaches the inner surfaces of the cooler basket 6 therethrough.
  • This compressed air source which is opposed to the air suction device 8, supports the detachment of the contaminants from the screen surface of the radiator basket 6.
  • the compressed air nozzle 31 is thus arranged just like the shielding plate 28 immediately in front of the interior of the shell side 13 of the radiator basket 6 in the immediate vicinity and opposite the cooling air cleaning device 7.
