    DESCRIPTION
    The invention relates to a harvesting machine which has a frame which surrounds at the rear a delimited engine compartment in which is disposed an internal combustion engine and a fueling device. sieving which can be positioned at the front of the engine compartment, which comprises a perforated filter element through which a fan can blow air back into the engine compartment.
    State of the art
    For self-propelled harvesting machines, various components, such as for example a charge air cooler, an oil cooler and the internal combustion engine, must be supplied with ambient air for the purpose of cooling during operation. Since ambient air is often heavily contaminated with fine dust particles during harvesting, sieving devices are used which include a perforated filter element through which ambient air is drawn in with a fan and sent to the refrigerants mentioned. Although such sieving devices are generally rotated and equipped with cleaning devices that suck or brush the particles from the surface of the filter element, maintenance work on the filter elements occurs from time to time. judicious in order to eliminate the remaining impurities and to ensure sufficient permeability of the filter element. Such sieving devices are usually attached to an outer wall of the harvesting machine and can pivot about the vertical axis in a maintenance position (DE 19 547 348 A1 or WO 01/36 794 A1).
    For other harvesting machines, the sieving device extends vertically to the front face of an engine compartment accommodating the internal combustion engine and transversely to the forward direction and the air is sucked laterally or to the face top of the walls of the harvesting machine and led through the sieving device (EP 0 481 203 A1, EP 0 667 447 A1 or DE 10 126 523 A1). For these sieving devices, no possibility is usually provided to conduct them without dismantling in a maintenance position, instead the maintenance is done by an operator on site at the front of the sieving device, in a practicable maintenance space provided therein within the harvesting machine. As the space is relatively narrow, the work there is difficult and uncomfortable.
    Finally, the embodiment according to DE 10 228 213 A1 is further described, in which the suction screen is movable in a vertical direction so that less impure air can be taken in at a higher height.
    Purpose of the invention
    The object of the invention is to provide a sieving device disposed in the interior space of an agricultural harvesting machine whose maintenance can be done without problems.
    Solution
    This object is achieved according to the invention by the teaching of claim 1, the dependent claims having features which improve the solution advantageously.
    A self-propelled harvesting machine comprises a frame on the rear side of which is arranged a motor compartment, which is delimited by walls or covers or similar elements. At the front side of the engine compartment is disposed a sieving device with a perforated filter element which corresponds to a fan generally disposed at the rear of the sieving device for conveying air through the filter element of the sieving device. and towards the rear in the engine compartment and to send the ambient air in refrigerants and other elements to supply fresh air. The flow of air flows from front to back through the filter element. The sieving device is arranged so as to allow movement in a direction extending horizontally and transversely to the forward direction of the harvesting machine between an operating position, in which it is located at the front of the engine compartment, and a maintenance position spaced apart from the engine compartment, in which it is shifted towards the outer side of the harvesting machine and is wholly or partially outside the lateral contour of the delimitation of the engine compartment.
    In this way, the maintenance of the sieving device is substantially facilitated, since it is accessible without any problem for an operator in the maintenance position.
    The possibility of moving the sieving device can be achieved by telescopic supports disposed on its upper face and / or on its lower face. Such supports comprise a first upright, rigidly connected to the frame and a second upright, which is arranged so as to move the outer side or the inner side of the first upright and maintains the sieving device. Between the two uprights, smooth and / or rolling bearings can be provided to facilitate movement. In addition, means are preferably provided to lock the second leg and the sieving device in the operating position and in the maintenance position.
    For a preferred embodiment of the invention, an interior space is provided at the front of the engine compartment, which is limited at the sides and upwards by walls and rearwards by the sieving device. One of the side walls can be interrupted by a lockable door, to give the operator access to the interior space preferably passable. Forward, the interior space is limited by components of the harvesting machine (such as an upwardly extending ejection well, a conveying device underneath and / or a grain treatment device and / or a front wall, to which a rear wall of a car can be connected or formed by the latter. The practical interior space allows the operator to store materials and access the mentioned components of the harvesting machine. The walls limiting the interior space upwards, and optionally the side walls, may be provided with openings through which the air is sucked.
    As the sieving device is positioned at a certain height above the ground, so that its maintenance is not possible from the ground or only with ladders or other climbing aids, it is appropriate to add to the chassis a platform disposed in front of or beside the engine compartment, from which an operator can reach the sieving device in the maintenance position. Such a platform may be formed by a console mounted on the frame or the upper face of a fuel tank protruding outwardly of the frame and the side walls of the harvesting machine.
    Embodiment Example With the aid of the figures, an exemplary embodiment of the invention is explained. The drawings show:
    Figure 1 is a schematic side view of a self-propelled harvesting machine in the form of a forage harvester, and Figure 2 is a perspective view of the sieving device offset in the maintenance position.
    FIG. 1 is a diagrammatic side view of a harvesting machine 10 in the form of a self-propelled forage harvester. The harvesting machine 10 stands on a frame with a frame 12, which is supported by front wheel drive wheels 14 and rear guide wheels 16. The control of the harvesting machine 10 is from a driver's cab 18, from which an accessory can be seen before harvesting in the form of a collector. Fodder harvested from the soil with the aid of the pre-harvest attachment 20, for example grass or the like, is conveyed via an input conveyor 22 with pre-pressing rolls, which are arranged inside an inlet housing 24 at the front of the forage harvester 10, at a chopper 26 in the form of a chopper drum located beneath the driver's cab 18, which shreds it into small pieces and transmits it to a secondary chopping device 32 and then to a conveying device 28. The crop leaves the harvesting machine 10 to a transport vehicle rolling next to it via an extraction shaft 30, the upper part of which is adjustable around an almost vertical axis and inclination. In the following, the direction indications, such as laterally, at the bottom and at the top, relate to the forward direction V of the harvesting machine 10, which extends to the right in FIG.
    The power supply for driving the pre-harvest attachment 20, the input conveyor 24, the secondary chopping device 32 and the transport device 28 as well as other additional driven elements and actuators of the machine Harvesting 10 is done (via mechanical hydraulic and / or electrical kinematic chains) from an internal combustion engine 34, which is disposed above the rear wheels 16 inside an engine compartment, 36. The engine compartment 36 is bounded on both sides by side walls 38, rearwards by a rear wall 40 and upwardly by a roof 42. The walls 38, 40 and the roof 42 generally have no function. but only serve to isolate the internal combustion engine 34 from the outside and are attached to supporting braces (not shown), which are mounted on the frame 12.
    The walls 38, 40 and possibly, but not necessarily, the roof 42 are provided with slit-like openings 44 through which air can exit. Through an opening in the roof 42 also extends an exhaust 46 of the internal combustion engine 34.
    The engine compartment 36 is bounded forwards by a sieving device 48 which comprises a perforated circular filter element 50 (see FIG. 2), which can be rotated by a drive around a horizontal axis 52 extending horizontally and forward direction V. In addition, the filter element 50 still corresponds to a cleaning device which removes impurities from the front face and from the rear face of the filter element 50 (not shown, see however EP 1 134 379 A2, the publication of which is incorporated by reference in these documents). At the rear of the sieving device 48 is a driven fan 54 with an axis of rotation extending coaxially with the central axis 52. At the rear of the fan 54 are different refrigerants 56, for which it can be used. act including an oil cooler of the internal combustion engine 34, a charge air cooler, a hydraulic oil cooler and an evaporator for an air conditioning installation for the driver's cab 18. It would be possible to interchange the positions of the fan 54 and the coolant 56. Up and to the sides, the sieving device 48, the fan 54 and the coolers 56 are sealed by a housing 58, in order to concentrate the air flow. After passing through the refrigerant 56, the air flow bypasses the internal combustion engine 34 and then reaches the outside through the openings 44. It would also be possible to equip the harvesting machine 10 with two engines 34 or more internal combustion with their refrigerants 56.
    At the front face of the screening device 48 is formed a passable interior space 60, which is limited forwards by a wall 62 located behind the rear wall of the driver's cab 18, the rear wall 64 of the fixed lower part. of the ejection well 30 and the housing of the conveying device 28. Upwards, the internal space 60 is limited by a roof 66 provided with air inlet slits 68. In operation, the fan 54 sucks the ambient air through the air intake slits 68. Finally, the interior space 60 is laterally limited by walls 70, in which a door 72 is provided. At the lower face of the interior space 60 is a fuel tank 74, which protrudes outwardly from the walls 70 and the frame 12 and can be filled via a tubing 84.
    Reference is now made to FIG. 2, with the aid of which it can be seen that the sieving device 48 is mounted in such a way as to allow lateral movement on the frame 12, so that it is movable between the operating position 1 and a maintenance position shown in FIG. 2. For this purpose, the sieving device 48 comprises a quadratic plate 76 with a central circular cutout in which the filter element 50 is disposed. The plate 76 is connected to its upper face and to its lower face to hollow uprights 78 extending horizontally and transversely to the forward direction V, which in turn receive in their interior space coaxial amounts 80, which are telescopically in their uprights 84, which are rigidly connected to the frame 12. Between the uprights 80 and the telescopic hollow posts 78 (and between the uprights 80 and 84), rolling bearings or plain bearings (not shown) can be arranged to reduce friction. If the travel distance offered by the two movable uprights 78, 80 should not be sufficient, third displaceable amounts (not shown) can also be interposed.
    The movable arrangement of the sieving device 48 allows the operator to enter the interior space 60 after opening the door 72, if necessary to open a lock of the sieving device 48 and then shift the sieving device 48 in the maintenance position according to Figure 2, wherein the sieving device 48 is outside the inner space 60. It can then be placed on the platform 82, preferably two-stage, formed by the face upper tank 74, and clean the filter element 50 of the sieving device 48, for example with compressed air, or perform other work. In addition, it now has access from the interior space 60 to the fan 54 and can perform work on the transport device 28 or assemble and disassemble the secondary chopper 32. Next, the sieving device 48 is again brought into the the operating position and the door 72 is closed, so that the operation of harvesting or road traffic can be continued.
