Definitions

  • the invention relates to a self-propelled harvesting machine with a drive motor, a cooler and a cooling fan with a cooling air cleaning device a filter to retain the dirt particles in the intake cooling air is arranged upstream with a suction device for removing suction Dirt particles, and the cooling air cleaning device by means of a switchable Drive can be driven.
  • the task is solved by either driving the Cooling air cleaning device can be switched or switched depending on the measured value of a sensor the suction housing and / or a shielding plate when the suction function is switched off by gravity or a motorized control in a the lower part of the Area covering position associated with the screening device is rotatable.
  • a sensor for example a Pressure sensor for measuring the air pressure in the intake area of the radiator fan or a temperature sensor for measuring the temperature of the cooling water Measured value determined, which gives an indication of whether there is still enough cooling air the cooling air cleaning device is sucked in. If the measured value falls below or above a critical limit, the drive of the Cooling air cleaning device switched on. The sensor continues to monitor the Course of the measured values and switches the drive of the cooling air cleaning device off again if the measured values are in an uncritical range. It is on this possible to operate the cooling air cleaning device only if that too is really necessary. This saves drive power and energy and the Aggretgate concerned are not exposed to senseless wear.
  • the second Alternative solution is when the cooling air cleaning device or at least whose suction is switched off, the lower part of the filter device covered.
  • cooling air from higher layers of air is preferably sucked in is less enriched with dirt particles than the ground-level air in the area a harvester.
  • the Gilter device clogs less quickly, and Depending on the amount of dirt, the cooling air cleaning device must be used less often or also not at all, as when driving on roads, even when in the area Dirt particles collected on the harvester in front of the air intake to have.
  • the drive for the cooling air cleaning device in particular the rotating or fixed filter element, the rotating or fixed suction housing and for the rotating or fixed shielding plate is preferably a common one Drive, but several individual drives can also be used.
  • the Suction housing and / or the shielding plate can in a particularly simple manner a part of the filter device assigned to the lower part of the filter device cover position can be rotated when using gravity.
  • Through the appropriate design of the suction housing and the shielding plate is a such a distance between the centers of gravity to the axis of rotation created that the Main focus with the drive switched off in the vertical projection of the axis of rotation level off.
  • the agricultural harvesting machine shown in FIG. 1 is a self-propelled Forage harvester 1, which is equipped with a chopping device which is explained in more detail is equipped on the output side with a post-accelerator in the form of a fan 2 is in order to get the chopped material into one with sufficient speed curved discharge chute 3, so that it is placed next to the forage harvester 1 moving transport vehicle is dropped.
  • the forage harvester 1 is also with a drive motor 4 in the form of a diesel engine.
  • a Rotating radiator fan 5 is provided, the one before or a cooler 6 is connected downstream.
  • a filter device 7 is arranged Directly in front of the cooler 6 .
  • the coat of the Filter device 7 and the end wall facing the discharge channel 3 for example made from a wire mesh or a perforated plate, but also other filter media can be used.
  • the Ejection channel 3 facing side a housing 8, which in a Design in a manner explained in more detail about the central central axis of the Screening device 7 can be driven in rotation.
  • the housing 8 is static and the filter device 7 can be driven in rotation.
  • this housing 8 is in a section towards it Rotation axis formed approximately angular, so that the approximately parallel to the rotation axis of the Housing 8 standing area the jacket of the filter device 7 corresponding to the Width of the housing 8 overlaps.
  • a maintenance room 9 of the forage harvester 1 Between the filter device 7 and the Ejection channel 3 is a maintenance room 9 of the forage harvester 1.
  • the housing 8 is with the blower 2 fluidically connected via a pipeline 10. On Vacuum generated by the blower 2 is introduced into the housing 8 via the pipeline 10 transfer.
  • FIG. 3 shows that the area of the Housing 8 is open, so that on the respective surfaces of the shell and the end wall a vacuum acts on the filter device 7 in order to suck off dirt particles.
  • the Housing 8 is rotatably mounted on a shaft 12.
  • the shaft 12 in a relatively small distance from the end wall of the filter device 7 shielding plate 13 designed in a rotationally fixed manner.
  • Inside the Pot-shaped filter device 7 are three at the same angular distance from each other arranged struts 11 are provided.
  • a drive 14 is located on one of the struts 11 mounted around the shaft 12 and thus the housing 8 and the shielding plate 13 to drive.
  • This drive 14 consists essentially of an electric motor 14a and a chain or belt drive 14b, wherein a wheel rotates on the Output pin of the electric motor 14a and the other wheel rotatably on the shaft 12 is put on.
  • the drive 14 can also deviate from the exemplary embodiment consist of a hydraulic drive, which is switched on and off by a hydraulic valve is switched off, or a belt drive with a detachable drive pulley or other switchable drive trains.
  • the shield plate 13 is in a cut in the direction of the shaft 12 angular and in one The view of the axis of rotation is segmented.
  • the shielding plate 13 extends approximately over one Range of 60 degrees over the inner surface of the jacket of the filter device 7. Die The end wall is also permeable to air and has an approximately triangular shape.
  • the forage harvester 1 is in a known manner in the front area with no closer explained good intake organs 15, which the chopper 16th is connected downstream. From the chopper 16, the material reaches one Conditioning roller pair 17 where it is crushed. So that the chopped material is perfect can be brought to a vehicle driving next to the forage harvester 1 the conditioning roller pair 17 of the post-accelerator in the form of the blower 2 downstream.
  • the cooler fan 5 In normal harvesting operation, the cooler fan 5 is driven in by the drive motor 4 driven, not shown. But also a thermostatically controlled, by an electric motor driven cooler fan 5 is possible. If the Radiator fan 5 presses or cool air through the cooler 6 depending on the design pulls, it sucks the cooling air through the cooling air cleaning device 20 the cooling air pass the filter device 7. If there are foreign objects on the mesh put the filter device 7, they hinder the free air flow, and the Air flow through the cooler 6 is reduced. This reduces the cooling capacity of the Radiator 6, and the coolant temperature rises. At the same time arises with one Radiator fan 5 arranged in a suction or pushing manner between the filter device 7 and the radiator fan 5 with increasing blockage of the filter device 7 increasing negative pressure.
  • the rising cooling water temperature can be caused by a Cooling water thermometer 22 are measured, the negative pressure between Filter device 7 and cooler fan 5 by a pressure gauge 24.
  • the measured values Such sensors 22, 24 can thus be used as a value for the degree of clogging Filter device 7 can be evaluated.
  • the sensors 22, 24 are connected via a Connection line connected to the drive 14, via which they the measured values Transmit drive 14 directly or indirectly.
  • the drive 14 cannot even with one Evaluation electronics shown in more detail, or the evaluation electronics is located elsewhere on the harvester.
  • the measured values of the sensors 22, 24 are compared with stored limit values and when the limit values are reached the drive 14 is switched on or off.
  • the shielding plate 13 is extended upwards with respect to its axis of rotation.
  • a locking device 18 fixedly arranged on a strut blocks at when the drive 14 is switched off, the shielding plate 13 and thus also the housing 8.
  • This locking device could be, for example, a lifting magnet, the Plunger moves into a hole in the shielding plate 13. This will make a unwanted oscillation of the housing 8 and the shielding plate 13 prevented.
