    Arrangement for lubricating a bearing of a crop conveying and / or processing arrangement of a harvesting machine
    description
    The invention relates to an arrangement for lubricating a bearing of a crop conveying and / or processing arrangement of a harvesting machine, comprising means for supplying lubricant from a storage container to the store, and a harvesting machine equipped therewith.
    Technological background
    Forage harvesters are used to harvest whole plants or their parts, which are picked up from a field during operation, pressed together by pre-press rollers and fed to a knife drum, the chopping knives of which cut the plants in cooperation with a counter knife. The cut plants or parts are then optionally fed to a conditioning device and conveyed by a post-accelerator into an ejection manifold which loads them onto a transport vehicle. The harvested plants are usually used as animal feed or for biogas production.
    When processing and conveying relatively green plant material, juices emerge from the plants, which penetrate into the bearings of the harvesting material conveying and / or processing elements of the harvesting machine and can lead to corrosion and damage there. An attempt is therefore made to protect the bearings from the plant juices by means of complex sealing systems (EP 1 695 612 Al).
    In order to protect the bearings of the rotating functional components, it is state of the art to protect them
    Shield BE2018 / 0072 from the outside with seals and lubricate them with grease in a defined quantity at defined time intervals. For this purpose, the bearings and storage environment with seals are usually constructed in such a way that a quantity of grease required for a specific bearing can be fed into and removed from the bearing. Due to the above external environmental conditions, dirt and water can nevertheless enter the bearing and damage it after a short period of time. High bearing temperatures can also contribute to early bearing failure.
    Another approach to extending the lifespan of bearings of grain processors is to apply an air-assisted lubrication mist to the bearings (Scherer brochure "2016 SDEI Processors and Replacement Kernel Processor Rolls", without print reference).
    task
    While under unfavorable circumstances the sealing systems cannot prevent plant juices from entering the bearings, the application of a pressurized mixture of oil and air to the bearings has the disadvantage that this mixture and the oil contained therein also escape from the bearing and can get into the crop.
    The object on which the invention is based is seen in providing an arrangement for lubricating a bearing of a crop conveying and / or processing arrangement of a harvesting machine and a corresponding harvesting machine in which the problems mentioned are avoided or at least reduced.
    invention
    The present invention is defined by the claims.
    BE2018 / 0072
    An arrangement for lubricating a bearing of a crop conveying and / or processing arrangement of a harvesting machine comprises means for supplying lubricant from a storage container to the storage and means for returning the lubricant from the storage to the storage container. In other words, a liquid lubricant is used which is operated in a circulation system.
    The lubricant can be mixed with air upstream of the bearing.
    The lubricant can be passed through a filter downstream of the bearing.
    The arrangement described can be used with any type of harvester, e.g. Combine harvesters, balers and forage harvesters. In the latter, the crop conveying and / or processing arrangement can be a pre-pressing roller and / or a chopper drum and / or a grain processor roller and / or a post-accelerator.
    embodiments
    An exemplary embodiment of the invention is explained on the basis of the figures. Show it:
    Fig. 1 is a schematic side view of a forage harvester, and
    Fig. 2 is a schematic plan view of a bearing of a grain processor of the forage harvester.
    1 shows a self-propelled forage harvester 10 in a schematic side view. The forage harvester 10 builds on a load-bearing chassis 12, which is from the front
    BE2018 / 0072 driven wheels 14 and steerable rear wheels 16 is worn. The forage harvester 10 is operated from a driver's cab 18, from which a harvesting attachment 20 in the form of a mowing attachment for the maize harvest, which is detachably attached to a feed housing 36, can be viewed. By means of the header 20 cut crop, z. B. corn or the like, is fed to the front of the forage harvester 10 via a feed conveyor 36 arranged in the feed housing 36 with pre-pressing rollers 30, 32 of a chopping drum 22 which it chops into small pieces in cooperation with a shear bar 46 and a grain processor with interacting rollers 28, 28 ', from which it reaches a conveyor device 24. The rollers 28, 28 'can be produced as cylindrical rollers which are toothed in the circumferential direction or can be designed to be wave-shaped in the axial direction. The material leaves the forage harvester 10 to a transport vehicle traveling along via an ejection elbow 26 which can be rotated about an approximately vertical axis and whose inclination is adjustable. The knives of the chopper drum 22 can be ground by a grinding device 42. In the following, directional information, such as laterally, below and above, relates to the forward movement direction V of the forage harvester 10, which runs to the left in FIG. 1.
    In the self-propelled forage harvester 10 shown in FIG. 1, rotating functional components such as the pre-compression rollers 30, 32, the chopper drum 22, the rollers 28, 28 'of the grain processor and the conveyor device 24 are exposed to very high loads. These high loads result from the high speeds and torques of the rotating functional units, which are necessary for picking up, processing and further transporting the crop. The bearings of these rotating components, in addition to the high speeds and forces mentioned, make the harsh environmental conditions of a self-propelled harvester difficult. These include a wide range of temperatures, heavy pollution from outside, water ingress, plant juices, vibrations, manufacturing and assembly tolerances.
    BE2018 / 0072
    The solution according to the invention for the problem is shown in FIGS. 1 and 2. The forage harvester 10 comprises a reservoir (tank) 50 for liquid lubricant, such as oil, a feed pump 52 which removes the lubricant therefrom and which supplies the lubricant to the individual bearings 56 of the pre-compression rollers 30, 32 and / or the chopper drum 22 and / or the rollers 28 , 28 'of the grain processor and / or the conveying device 24, one of which is shown in FIG. 2, and a filter 54, through which the lubricant returning from the bearings 56 is filtered before it returns to the reservoir 50. A petrochemical or synthetic or vegetable agent, in particular oil, can be used as the lubricant.
    FIG. 2 shows a bearing 56 which rotatably supports a shaft 58 or axis of the rollers 28, 28 'of the grain processor directly or indirectly on the chassis 12 of the forage harvester 10. The bearing 56 comprises, in a manner known per se, an inner bearing ring 60 which is connected to the shaft 58, an outer bearing ring 62 which is connected to the chassis 12 and rolling elements 76 arranged therebetween, which are arranged in two axially spaced rows between the bearing rings 60 , 62 are arranged and distributed around the circumference of the shaft 58. A labyrinth seal 74 seals the bearing 56 from the crop flow, as is known per se from EP 1 695 612 A1.
    A lubricant line 76 feeds the lubricant from the feed pump 52, which is metered by a flow control valve 64 and is supplied (and in particular injected) to the rolling elements 76 from above through a feed channel 66 penetrating the outer bearing ring 62, e.g. radially from the outside into a region between axially adjacent rolling elements 76, as shown in FIG. 2. A connection channel 68, which is diametrically opposite the feed channel 66 and is arranged on the underside of the bearing 56, extends from both regions adjacent to the outer sides of the rolling elements 76 and likewise penetrates the outer bearing ring 62
    BE2018 / 0072
    Connection channel 68 is in turn connected to an outlet channel 70, which is connected to a suction pump 72, which in turn supplies the extracted lubricant to the filter 54
    At the other end of the rollers 28, 28 ', which is not shown in FIG. 2, a further bearing 56 is arranged, which is generally mirror-symmetrical to the bearing shown in FIG. The bearing 56 shown in FIG. 2 could alternatively or additionally be assigned to the pre-pressing rollers 30, 32 and / or the chopping drum 22 and / or the conveyor device 24.
    After all, it is proposed to design the rolling elements 76 and the bearing rings 60, 62 of the bearings 56 such that they are no longer supplied with a certain amount of grease, but rather are lubricated with a circulating amount of liquid lubricant. For this purpose, the bearings 56 are connected to the circulating lubrication described, which supplies each individual bearing 56 with a certain amount of lubricant, which in particular can be oil. Each bearing 56 supplied with lubricant has an additional outlet channel 70, into which the supplied lubricant can flow off again. The outflowing lubricant from all bearings 56 is collected, fed to the filter 54 and finally fed into the reservoir 50, which also takes on the function of a cooler. The lubricant is then sucked out of this reservoir 50 by means of the (optional) feed pump 52 and fed back to the bearings 56 in order to lubricate and cool them. A flow control valve 64 is connected upstream of each bearing 56, by means of which the respective amount of lubricant required for the bearing 56 can be adjusted. The labyrinth seals 74 are designed in such a way that a higher pressure level than in the surroundings can prevail in each bearing 56 and an undesired leakage of lubricant from the bearing 56 to the crop is avoided. For this purpose, in contrast to that shown in FIG. 2, the attachment of the sealing lips 78 can be reversed compared to the prior art. The entry of dirt and water from
    BE2018 / 0072 outside in the bearing 56 is thus thereby avoided that the bearing 56 is pressurized.
    A particularly advantageous lubrication is obtained if the lubricant supplied to the bearing 56 is an oil-air mixture.
    For this purpose, a suitable atomizer (not shown) can be inserted into the line 76 or the feed channel 66.
