Definitions

  • the invention relates to a cleaning device for cleaning a suction surface of an air filter of a cooling unit provided in a harvesting machine with at least one cooler having a blower for an internal combustion engine or an air conditioning system, the dirt particles adhering to the suction surface via a suction part provided outside the cooling air housing, a suction line connected to this, connected to a vacuum side of the cooling air housing and an outlet opening are released into the open.
  • An internal combustion engine with a cleaning device for a fixed filter is known (US-A-3155473), which consists of a filter arranged in front of the screen.
  • the pressure part is connected via a compressed air line to a compressed air nozzle which is pressurized with compressed air via a propeller arranged on the internal combustion engine, so that it can then be pressed through the sieve in order to press the dirt particles out of the air filter.
  • a cleaning device for cleaning the air filter for an internal combustion engine installed in a combine harvester is also known (DE-A-2 418 054), which is surrounded by an engine cowling.
  • This cladding has a front wall with air inlet openings, on the outside of which a stationary suction part is arranged, which is connected to the blower of the internal combustion engine via a suction line.
  • the air filter consists of a pot-like sieve and is rotatably mounted in the outer wall of the combine harvester, which is part of the engine cowling, and sealed against the wall of the housing. Furthermore, the air filter must be driven by an additional drive device.
  • a cleaning device for cleaning an air filter of the type mentioned at the outset is known (US Pat. No. 3,837,149), which consists of a rotatably mounted air filter which is provided in a housing for receiving the internal combustion engine and which has to be cleaned via a suction nozzle. A part of the suction nozzle is guided along the outer surface of the rotatably mounted air filter and is operatively connected via a suction nozzle to a further propeller which is driven by the power take-off of the internal combustion engine.
  • the air filter is driven by a special drive device, which is also arranged in the housing for covering the internal combustion engine.
  • Such a device is relatively complex and expensive, since the rotatably mounted air filter must be sealed, so that no kei. l e dirt particles can enter in the area of the air filter bearing.
  • the invention has for its object to improve a harvesting machine with a cleaning device for a fixed air filter so that a good cleaning of the air filter can be achieved with simple structural means while saving on driving means.
  • This object has been achieved in that the suction part is rotatably mounted in front of the suction surface and is assembled with at least one propeller part or is designed as such to generate the drive torque.
  • the cleaning device Due to the advantageous design of the cleaning device, it is possible to achieve effective cleaning of the air filter in a simple manner using fewer components, for which purpose the suction part moves in front of the surface of the air filter and in each case generates a negative pressure on the surface to be covered, so that there adhering dirt particles are removed and then gradually move to the center, where they can be discharged via the blower line to the outside. Due to the rotatable mounting of the suction part via the propeller part assigned to it, a drive for the suction part is created in a simple manner, so that a complex additional drive device for the suction part is no longer necessary. Since the blower air has the same flow direction as the dirt particles to be extracted, they can be discharged to the outside via the blower, which is located behind the cooler.
  • the suction surface forms the surface of the cooler or the surface of an air filter upstream of the cooler, as seen in the flow direction, a continuous inlet opening of the suction part sweeping approximately the entire suction surface.
  • the suction part has at least one inlet opening at its outer end and that the suction part consists of a U-shaped support open on three sides, the opposite legs of which are exposed in the area of the outer end so that they are connected to the web of the U-profile support form an obtuse angle, while the leg piece adjoining the exposed part forms a right angle with the web.
  • the dirt particles which are pressed onto the surface of the air filter by the air flow entering the air filter, are sucked off by the rotating suction nozzle, since no contact pressure affects the dirt particles below the suction part, so that they detach from the surface of the air filter can.
  • the suction flow below the suction part the dirt particles are guided to penetration and through the suction line through the air filter into the adjoining blower line, which is connected to an outlet opening of the blower housing.
  • This arrangement creates an effective suction device in a simple manner, which can be driven at the same time by the air entering the air filter. Since only the suction part rotates and the air filter is firmly connected to the blower housing, a relatively expensive seal for the air filter can be dispensed with.
  • the suction part can be designed so that it also works as a propeller. However, it is also possible that the propeller is detachably connected to the suction part. In this way you get two individual components that are much easier to manufacture.
  • the suction part has a propeller which can be releasably connected to it and which is arranged offset with respect to the suction part as seen in the direction of rotation. It is also advantageous that the axis for receiving the suction part is received in a holder which is detachably connected to a wall of the harvesting machine or to the air filter or to a part of the suction line.
  • the suction part is arranged concentrically to the inlet opening and is rotatably received at the front end of the suction line. It is also advantageous that the cross section of the suction part widens towards the axis of rotation and is triangular or semicircular. It is also advantageous that the suction line can be formed from one or more detachably connectable parts.
  • the suction part can either be rotatably mounted directly in a holder connected to the filter or can be received in a holder which is attached to the outside of the combine harvester.
  • the drive of the suction part can be improved in that the web of the suction part has an incision in the area of its two outer ends, at the end edge of which runs parallel to the longitudinal axis of the suction part, an angled part is connected in the direction of the air filter, the surface of which is approximately parallel to the The surface of the other exhibited part runs.
