Definitions
- the invention relates to a self-propelled harvesting machine, especially a self-propelled forage harvester to pick up and Chopping corn, wilting grass, green fodder and similar crops with one surrounded by a machine wall, with a fresh air supply connectable drive motor, a cooling unit for cooling machine units like the drive motor, a cab, a hydraulic and Gear oil and the like, and with a cleaning device for sucked cooling air, which is an upstream in the flow direction, in Rotating movement displaceable screening device, one of the screening device associated vacuum chamber and a suction fan.
- a self-propelled harvesting machine of the aforementioned type is known from EP 0 481 203 B1 known.
- This self-propelled harvesting machine there is the vacuum space in front of the screening device with the intake duct of the throwing fan Harvester connected so that accumulating in the cooling air Dirt particles are sucked through the throwing fan and through with the crop the machine ejection can be carried out.
- the crop is contaminated by contaminants extracted from the cooling air.
- EP 0 313 763 B1 is a self-propelled harvesting machine known, in which a vacuum in the vacuum chamber in front of the screening device is generated via an injector nozzle arranged in the exhaust pipe.
- the suction power to be generated is low. This also goes for an increased Risk of fire due to the hot exhaust system Dirt particles.
- This provides a self-propelled harvesting machine in which the Transverse wall the interior of the machine in an area of cleaned air and separates into an area of not yet cleaned air.
- the drive motor and Its aggregates are behind the cooling air drawn in in the direction of flow the transverse wall and thus arranged in the area of cleaned air.
- the Cleaning device for sucked cooling air as well as cleaning device parts for the fresh air supply to the drive motor are in Direction of flow of the cooling air seen in front of the transverse wall and therefore in Area not yet cleaned air arranged so that neither a crop flow nor the drive motor and its aggregates contaminated with dirt particles can be. Dirt particles filtered out of the supplied air can be taken from the room in front of the transverse wall and with outside the Remove cleaned air from the interior of the machine.
- the transverse wall is preferably formed by machine units. So the cooling unit preferably forms part of the transverse wall itself.
- An air intake box for the fresh air supply to the drive motor can also be used for example with its wall facing the drive motor part of the Be transverse wall.
- the transverse wall including this forming Parts extend through the entire interior to the side, upper and lower engine room boundaries and is convenient connected to the machine wall via sealing elements such that a consequent separation between the room of cleaned air and the room not yet cleaned air is realized.
- the air intake for the z. B. central cooling unit, the z. B. an air cooler for the fresh air cooling of the drive motor, a liquid cooler for the Drive motor, an oil cooler for hydraulic and gear oil, and a cooler for the air conditioning system can include a driver's cabin is expediently carried out via the rotatable sieve and the Suction blower assigned to the screening device.
- a driver's cabin is expediently carried out via the rotatable sieve and the Suction blower assigned to the screening device.
- Removing filtered out dirt particles is a preferred method Development of the invention provided an additional suction fan that with the vacuum chamber of the screening device is connected.
- an air intake box for the fresh air supply of the drive motor this additional suction fan connected via suction channels, so that over the additional suction fan the total in the area in front of the transverse wall accumulated dirt particles centrally via the suction fan from the Machine interior can be removed without the crop flow or drive motor parts come into contact with these dirt particles.
- the vacuum in the Vacuum chamber of the screening device as well as a vacuum in one Air intake box for the fresh air supply to the engine are generated.
- the suction pressure can be used to clean the air intake box regulate the fresh air supply to the engine so that it must be ensured that the Suction pressure for dirt particles is set, which meets the requirements of a optimal fresh air supply to the drive motor is taken into account. This happens for example via a pressure sensor in the wind hood in the Machine interior is arranged in front of the transverse wall and depending of the static pressure controls the adjusting element.
- the Fresh air supply to the drive motor is given priority.
- a major advantage of the harvesting machine according to the invention is that Operation of functional parts of the drive motor and the exhaust system of the Drive motor are not affected. Extracted dirt particles can be stored centrally in the field without the drive motor and its Aggregates and crop are contaminated. A fire risk from Dirt particles in the engine system or in an exhaust gas box are avoided. In addition, parts of the cleaning unit and the cooling unit are central accessible so that the maintenance friendliness of the machine is also improved is.
- a central cooling unit 8 provided that part of a machine interior 6 across and bottom to top penetrating transverse wall 9, which the machine interior 6 in an area 10 of cleaned air and in an area 11 still divided into unpurified air.
- the cooling unit 8 is intended for cooling air for cooling the Fresh air from the engine, a cooler for the engine cooling, a cooler for oil cooling and a cooler for cabin cooling.
- FIG. 2 is a sectional view according to section lines II-II in FIG. 1 shown.
- the screening device 12 is also the Cleaning device for sucked-in cooling air can be seen, the sieve wheel 12.1 has that by an electric or oil motor 14 and one of a tension roller 15th tensioned belt 16 is set in rotation.
- the Screening device 12 sits directly in front of the cooling unit 8, which in turn is part of the is the transverse wall 9 penetrating the machine room 6.
- the Machine wall 7 directly adjoins the transverse wall 9, possibly below Intermediate layer of sealing elements 7.1 and closes on the floor side via floor parts 18 on the machine side members 17.
- FIG. 3 Behind the screening device 12 (FIG. 3) is a suction fan 19 (main fan) arranged, which sucks in the cooling air through the screening device 12.
- a suction fan 19 main fan
- In Flow direction of the cooling air in front of the screening device 12 is one Vacuum chamber 20 arranged with another suction blower 21 (see also Fig. 3) is connected.
- This further suction fan 21 is in the vacuum chamber 20 generates a negative pressure, so that in the course of Rotational movement of accumulated dirt particles from the screening device 12 via the vacuum chamber 20, the further suction fan 21 and one Delivery channel 22 can be placed in the field.
- the suction fan 21 is via a belt 23 with tension pulley 24 from the drive of the suction fan 19 driven out.
- An air intake chamber 25 is provided for supplying fresh air to the drive motor 5 provided by a sieve or a mesh having door 26 is closable.
- the lower area 29 of this Air intake box 25 is through a suction channel 27 with the other Suction blower 21 and the vacuum chamber 20 also via a suction channel 28 connected to the suction fan 21.
- About the suction channel 27 can lower area 29 of the air intake box 25 filtered out dirt particles Delivery channel 22 are supplied.
- the suction channels 27, 28 can also in Partial areas form a common channel
- An adjustment member in the form of an air flap 30 is located within the suction channel 27 arranged, via which the negative pressure in the lower region 29 of the air intake box 25 can be set. This happens depending on the static pressure in the wind hood 31 via a pressure sensor 32, so that the dirt particle suction from the lower region 29 of the air box 25 the other operating parameters of the drive motor 5 are not disruptive can influence. The fresh air supply to the drive motor 5 given priority.
- the air duct can be seen in more detail from FIG. 4.
- a fine filter 33 and goes accordingly arrow 34 for example, to the turbocharger of the drive motor.
- secreted small dirt particles from the sieve or the mesh of the Door 26 can not be filtered out, according to the direction of arrow 35 the suction channel 27 as well as dirt particles from the vacuum chamber 20 according to arrow 36 via the further blower 21 and the discharge channel 22 removed from the inside of the machine and already in the field in one harvested area. So pollution risks of the Drive motor or the crop excluded.
