    EXHIBITION FIELD
    [001] This exhibition generally refers to the harvesting of sugarcane, including the crushing of sugarcane into pieces of stalk. BACKGROUND OF THE EXHIBITION
    [002] To harvest sugar cane from a field, a sugar cane harvester can cut sugar cane plants into stems. The rods can then be moved by various rollers or other mechanisms for crushing drums, which can cut the rods into relatively uniformly sized pieces of stem. The operation of such crushing drums can provide significant vibrations and other disturbances for the sugarcane harvester in general, including for a harvester operator's cab.
    [003] In several cases, and for several different reasons, different crushing drums (or crushing drum configurations) can be used for the same combine. For example, a set of crushing drums (or crusher drum configuration) can be used when sugar cane is being harvested for processing to form sugar or other products, while a different set of crushing drums (or drum configuration) crusher) can be used to cut sugar cane into pieces of stem for replanting. This may require the removal of a set of crushing drums, so that a different set (or the same set configured differently) can be installed. It may also be necessary to remove or replace multiple crushing drums (and related mechanisms) at different times for cleaning and maintenance purposes. EXHIBITION SUMMARY
    [004] A crusher drum module for a sugarcane harvester with a chassis and a feeding mechanism is exposed. According to one aspect of the display, the module may include a module frame, distinct from the chassis. The module frame may include first and second drum holes on each side of the module, the first drum holes and the second drum holes supporting, respectively, first and second crushing drums for parallel rotation. A plurality of mounting devices can be affixed to the module frame or chassis, where, when the plurality of mounting devices are in an engaged state, the module frame is attached to the chassis by the mounting devices, whereby the drums crushers are lined up to receive sugar cane from the feeding mechanism. When the plurality of mounting devices are in a disengaged state, the module frame and crushing drums are collectively removable from the chassis and the sugarcane harvester.
    [005] In certain embodiments, one or more of the mounting devices may include a vibration damping device to reduce the transmission of vibration between the chassis and the module frame when the module frame is attached to the chassis. The vibration dampening device may include one or more rubber elements interposed between the chassis and the module frame. A compression element can propel the rubber elements against a display element on the module frame or on the chassis to secure the module frame to the chassis.
    [006] In certain embodiments, a gearbox for driving the crushing drums, the gearbox being mounted on the module frame can be mounted to the module frame, such that, when the plurality of mounting devices are in the state disengaged, the gearbox is collectively removable from the sugarcane chassis and harvester with the module frame and crushing drums.
    [007] In certain embodiments, each drum hole is surrounded, at least in part, in an outer portion of the module frame by the face plate. The face plate can provide an alignment surface to align the rotation of the shredder drums, respectively.
    [008] In certain embodiments, a bearing support for each crushing drum may include a mounting plate affixed to the module frame and a neck supporting a bearing for the rotation of the crushing drum. The mounting plate can be attached to the outside of the module frame and the neck can extend through the associated drum hole into the frame. The neck can support the bearing for the crushing drum inside the crushing drum. The mounting plate can be placed on the face plate.
    [009] Details of one or more implementations are set out in the attached drawings and in the description below. Other features and advantages will be apparent from the description, the drawings and the claims. BRIEF DESCRIPTION OF THE DRAWINGS

    [0023] The following describes one or more example modalities of the crushing drum module, as shown in the attached figures of the drawings briefly described above. Several modifications in the example modalities can be contemplated by a person specialized in the technique.
    [0024] Traditional sugarcane harvester designs can introduce a number of problems with crushing drums. As noted above, in order to harvest sugar cane from a field, a sugarcane harvester can cut sugar cane plants from the ground, then direct the cut stems or stems through from several feed rollers (or other feed mechanism) to a set of crushing drums. When driven, for example, by one or more hydraulic motors, the crushing drums can rotate in reverse, so that the blades affixed to the crushing drums pass in close proximity and cut the sugarcane stems into relatively large pieces of stalk. uniform. In certain historical configurations of sugar cane harvesters, these crushing drums and feed rollers can be collectively supported in a single harvester chassis. Among other problems, this can result in the transmission of significant vibration through the harvester, including to a harvester cab, during the rotation of the crushing drums. Also, due to the extreme nature of sugarcane harvesting operations, it may be necessary to change the crushing drums (and crushing drum configurations) relatively frequently. With historical configurations of sugarcane harvesters, this may tend to require a significant investment of time and activity.
    [0025] The exposed crusher drum module (and related sugarcane harvester) can address these and other problems. In certain embodiments, a module frame may be provided to rotatively support the crushing drums of a combine. The module frame can be constructed as a separate component from the harvester chassis, so that the module frame, together with the crushing drums, can be collectively removed intact from the harvester chassis. This can allow removal of the crushing drums from the combine without extensive disassembly of associated gearboxes, bearing assemblies, and others, as may be required for traditional combine designs. In addition, this can allow operators to maintain multiple crushing drum modules, each with different crushing drum configurations, and easily swap between the various modules when necessary (for example, to harvest seeded cane, and others).
    [0026] In certain embodiments, the various vibration dampening devices (or vibration isolators) can be attached to the module frame and used to attach the module frame (and, correspondingly, the crushing drums) to the harvester chassis. For example, several rubber vibration isolators can be used as part of the mounting devices used to attach the module frame to the chassis, so that the transmission of vibrations between the crusher drum module and the chassis (and the harvester in general ) is reduced. This can significantly improve the operator's experience during combine operation. Also, this reduction in vibration transmission can reduce the wear of, and the chances of misalignment, the crushing drums and the various other components of the combine.
    [0027] Crusher drum modules with these characteristics (and others) can provide several advantages in addition (or as an alternative) to increasing the ease of removing and replacing crushing drums and reducing the transmission of vibrations to, and from , feed rollers and crushing drums can be constructed through various welding operations. Such welding can tend to distort the portions of the chassis, which can lead to misalignment of the axes of rotation of the various crushing drums, when the drums are mounted to the chassis. This can result in sub-optimal (eg, non-uniform) cutting of sugarcane stalk pieces, as well as several other problems, including excessive wear, and premature failure, of drums and associated components (for example , support bearings). In contrast, a removable crusher drum module, as discussed in more detail below, can be configured to reduce the incidence of such distortion and misalignment, and thus contribute to the higher quality cutting of stalk pieces and the generally improved operation of the crushing drums and other components.
    [0028] As will become apparent from the discussion here, the exposed crusher drum module can be used advantageously on a variety of equipment and with a variety of machines. In certain embodiments, with reference now to figure 1, the exposed module can be included in a sugarcane harvester 20. It will be understood, however, that the exposed crusher drum module can be used for various other vehicle platforms or not vehicles, including several sugar cane harvesters of different configurations or designs, different from the sugar cane harvester 20 in figure 1.
    [0029] Combine harvester 20 is shown in a side view in figure 1, with the front part of the sugarcane harvester 20 facing left. Consequently, certain components on the right side of the harvester 20 may not be visible in figure 1. The harvester 20 may include a main frame 22, supported on track assemblies 24 or wheels (not shown), with a cab 18 to house an operator. A motor 26 can provide power to drive the harvester across a field and to power several driven components of the harvester 20. In certain embodiments, motor 26 can directly energize a hydraulic pump (not shown) and several driven components of the cane harvester sugar-20 can be powered by hydraulic motors (not shown) that receive hydraulic energy from the hydraulic pump through an integrated hydraulic system (not shown).
    [0030] A cane spindle 30 can extend in front of the frame 22 in order to remove the leafy tops of the sugarcane plants (not shown), and a set of 32 system harvest dividers (only the left side divider 32 shown in figure 1) can then guide the rest of the sugarcane towards the internal mechanisms of the combine 20 for processing. When the combine 20 moves across the field, the plants that pass between the crop dividers 32 can be deflected downwards by one or more rollers 36, before being cut close to the base of the plants by means of a cutter set. base 34, mounted on the main frame 22. The rotation of the disks, guides, blades (not shown) on the base cutter assembly 34 can also direct the cut ends of the plants up and back inside the harvester 20, in the direction for successive pairs of upper and lower feed rollers 38 and 40. Feed rollers 38 and 40 can be rotatably supported by a chassis 28, and can be rotatably driven by a hydraulic motor or other device (not shown) to transport the stems in the direction for a crusher drum module 42 for crushing into relatively uniform pieces of stalk.
    [0031] As described in greater detail below, the crushing drum module 42 can include upper and lower crushing drums 44 and 46, respectively, which can rotate in opposite directions around, respectively, parallel axes 62 and 64 (see figure 7) in order to crush the stems in passing to form stalk pieces and propel the stalk pieces into a cleaning chamber 48 at the base of a primary extractor 50. The primary extractor 50 can use an energized fan to extract waste and debris from the cleaning chamber 48. A loading elevator 52, with a front end positioned at the bottom of the cleaning chamber 48, can then transport the cleaned stem pieces upwards to a discharge location 54 below a secondary extractor 56, where stalk pieces can be unloaded onto a tow truck or other receptacle (not shown).
    [0032] With reference also to figures 2A and 2B, the crushing drums 44 and 46 can each include a number of blades 58, which can be affixed to the body of the drums 44 and 46 in various known ways. With particular reference to figure 2B, when the crushing drums 44 and play arm 46 rotate in reverse (ie, they rotate in opposite directions), the tips of successive blades 58 can pass within the relatively close proximity to each other, the in order to cut the sugar cane into pieces of stalk for further processing. Crushing drums 44 and 46 are shown in figures 2A and 2B as having three blades 58 in each. It will be understood that other configurations may be possible. For example, certain crushing drums may include four or more blades, while others (for example, cane seed crushing drums) may include only two blades.
    [0033] For several reasons, it can be important to ensure that the cane pieces cut by blades 58 are relatively uniform in size. For example, fan-based separation within primary extractor 50 may depend on a relatively uniform size of leaf pieces and stalk pieces, in order to exploit the density differences between the leaves and the stems, to remove the leaves at from the combine. This uniformity, in turn, may depend on a relatively precise alignment of the crushing drums 44 and 46 with each other. This can result in more complete cutting of the sugarcane material, including the sugarcane leaves, at the first point along drums 44 and 46 than at the last. With such a non-uniform cut, the extractor 50 may not separate the leaves from the stalk, as effectively as may be desired. Consequently, it may be useful to ensure that the two drums 44 and 46 rotate about the relatively parallel axes 62 and 64.
    [0034] As noted above, the design of certain traditional sugarcane harvesters can create problems in this and other aspects of the crushing drum operation. For example, where a harvester's crushing drums are mounted on a single unit chassis (for example, which can also support multiple feed rollers, and other harvester components, such as a loading elevator), the welding operations required for chassis construction, they may tend to warp or otherwise distort portions of the chassis. This can lead to difficulty in maintaining the proper rotational alignment of the crushing drums.
    [0035] Still, with a unitary chassis, forces from the other portions of the harvester can be transferred directly to the crushing drums (or to the supporting components, such as bearings, drum bores, and others), resulting in another misalignment crushing drums. For example, with reference again to figure 1, the loading elevator 52 can weigh 5,000 pounds or more, and can rotate from side to side on the combine 20, when supported by the guidance table 60 and the chassis 28, thus imposing forces of distortion on the chassis 28. With an integral chassis design of certain historic harvesters, these forces can tend to misalign the crushing drums.
    [0036] Consequently, with reference also to figure 3, it may be useful to provide a module frame 70 for the crusher drum module 42, which is both distinct from chassis 28, and relatively easily removable from chassis 28. In the represented embodiment, by For example, module frame 70 can generally include side elements 72a and 72b (collectively referred to here as side elements 72), connected by several cross elements 74. In certain embodiments, side elements 72 and cross elements 74 can be formed of sheets metal, properly shaped and joined. As shown, for example, side elements 72 include side metal plates that are connected by transverse elements 74 of sheet metal. It will be understood, however, that other configurations may be possible. In certain embodiments, several of the elements 72 and 74 may include features to provide additional structural strength for the module frame 70. For example, the side elements 72 may include several folds 78 along the opposite long edges of the side elements 72. The elements sides 72 can generally be shaped in order to slide in and out of an appropriate space in the chassis 28, as described in more detail below (see, for example, figures 9 and 10).
    [0037] Each of the side elements 72 may include an upper drum bore 80 to support the rotation of the upper crusher drum 44, and a lower drum bore 82 to support the rotation of the lower crusher drum 46. In certain embodiments, several deflectors (for example), deflector 76, or deflector 102 (see figure 2) can be provided with respect to drum holes 80 and 82, in order to properly orient the pieces of stem cut by the upper crusher 44 and lower crusher drum 46 into the cleaning chamber 48 (see figure 1).
    [0038] In certain embodiments, "stand-off or metal face plates 84a, 84b, 86a, and 86b, (referred to here collectively as face plates 84 and 86) can generally surround the drum holes 80 and 82, respectively, on the outer side of the side elements 72 (see figures 6 and 7 for face plates 84a and 86a). As discussed in more detail below, these plates 84 and 86 can be appropriately planed or machined in order to provide an appropriately flat surface to support various mounting mechanisms for crushing drums 44 and 46. In this way, plates 84 and 86 can ensure rotation properly parallel to drums 44 and 46, even if module frame 70 is distorted in creation holes 80 and 82 or, otherwise.
    [0039] In order to attach the module frame 70 (and thus the entire crusher drum module 42) to the chassis 28, a number of mounting devices can be affixed to the module frame 70 (or another component of module 42 ). As shown, for example, two lower mounting brackets 92 and an extended upper mounting bracket 96 (see also figure 5), with the reinforcement ribs 100, can be screwed to the cross members 74 of the module frame 70. (will be understood that various other mounting device numbers and configurations may be used.) These brackets 92 and 96 can then be screwed, or otherwise secured, to the corresponding mounting locations on the chassis 28, in order to removably secure the module frame 70 to the chassis 28. (It will be understood that the module frame 70 can additionally (or alternatively) be attached to various other characteristics of the harvester 20.) In certain embodiments, the supports 92 and 96 can be attached to the module frame 70, when the crusher drum module 42 is inserted into (or removed from) the sugarcane harvester 20. In certain embodiments, the supports 92 and 96 can be attached to the module frame 70, then that the crusher drum module 42 is inserted into the combine 20 (or detached from the module frame 70, before module 42 is removed from the combine 20).
    [0040] In certain embodiments, the various mounting devices (for example, including mounting brackets 92 and 96) may include various vibration damping devices, such as insulators 94 and 98). As discussed in more detail below, insulators 94 and 98 can include various rubber elements (or similar), interposed between module frame 70 and chassis 28, in order to inhibit the transmission of vibrations between frame 70 and chassis 28. Module 42 is represented with four total insulators 94 and 98. It will be understood, however, that any number of insulators can be used.
    [0041] With reference also to figures 4 and 5, in certain modalities, the module frame 70 and the chassis 28 can be configured in such a way that the crushing drums 44 and 46, as well as several other components, can be installed in the frame. module 70 before module frame 70 is inserted into combine 20 and attached to chassis 28. In this way, for example, when maintenance or substantially is required for a crusher drum assembly, an operator can disengage the various mounting devices (for example, example, you can unscrew the connections between chassis 28 and mounting brackets 92 and 96) and then remove the entire crushing drum module 42, including module frame 70 with the crushing drums 44 and 46 still mounted on it, from chassis 28. Also, in certain operations, the operator may have an alternative, pre-configured crusher drum module (not shown), already prepared for installation on combine 20, so that the operator you can simply swap the crusher drum module 42 installed by the alternative preconfigured, then continue the combine operations without another delay. For example, an operator can configure a first crushing drum module with crushing drums suitable for normal sugar cane processing, and can configure a second crushing drum with crushing drums configured to cut seeded cane. In this way, because of the modular nature of the exposed crushing drum module, an operator can switch between normal harvesting and sowing cane harvesting, simply by detaching and removing the entire first module, then inserting and securing the second module. In contrast, with more traditional designs, an operator may be required to disassemble and detach an associated gearbox, disassemble and remove various bearing supports, then remove the crushing drums individually.
    [0042] In certain embodiments, a gearbox 108 can be attached to the module frame 70, in order to trigger the rotation of the crushing drums 44 and 46. As shown in figures 4 and 5, for example, the gearbox 108 can be screwed, or otherwise affixed, to side member 72b of module frame 70. Gearbox 108, as shown, may include a cover 110, an input shaft 112, configured to receive rotational energy from a hydraulic motor (not shown), and a stub axle 114, configured to provide rotational energy for an associated flywheel (not shown). Several internal gears (see figure 7) can direct the rotational energy of the input shaft 112, with appropriate relative timing, to each of the crushing drums 44 and 46 and the flywheel.
    [0043] In certain embodiments, gearbox 108 can be configured to also be removed from the chassis collectively with module frame 70 and crushing drums 44 and 46. For example, in the embodiment shown in figures 4 and 5, the contours outer covers 108 may not extend beyond the outer edges of side member 72b. Consequently, when module frame 70 is detached from chassis 28 and gearbox 108 remains bolted to module frame 70, gearbox 108 and module frame 70 can be removed together from harvester 20 via of the same space (s) or opening (s) in the chassis 28 (or other components of the combine 20). This can also facilitate a relatively easy transition between various harvesting modes or other swapping or maintenance of the crushing drums. For example, an operator can maintain a first crusher drum module with a first gearbox and potentially a first hydraulic motor for normal harvesting and a second crusher drum module with a second gearbox in order to switching between normal harvesting and sowing cane, an operator can detach the frame of the first module from the chassis 28, detach the first module from the hydraulic system of the combine 20, and remove the entire first module from the combine 20. Then , the operator can insert the entire second module, attach the second module to the hydraulic system of the combine 20, and attach the frame of the second module to the chassis 28.
    [0044] Crushing drums 44 and 46 can be mounted on module frame 70 for rotation, in a variety of ways. In certain embodiments, with reference also to figures 6 to 9, several bearing supports 130 can be provided, which can be attached to the side element 72a, opposite the gearbox 108. For clarity of presentation of the various components, only one support lower rolling element 130 for lower drum bore 82 (and lower crushing drum 46) is shown in the various figures. It will be understood, however, that an upper bearing support (not shown) can be provided for the upper drum bore 80 (and upper crushing drum 44).
    [0045] In certain embodiments, each bearing bracket 130 may include a disc-type mounting plate 132, which can be screwed (or otherwise affixed) to the side element 72a, and seated on the associated face plate 84a or 86a. As noted above, the outer surfaces of face plates 84a and 86a can be finished (for example, by machining, polishing, and the like), before or after the creation of drum holes 80 and 82, in order to provide a relatively smooth surface. flat, extending in a normal direction with respect to the desired axes of rotation 62 and 64 of the crushing drums 44 and 46. In this way, even if some amount of distortion or warping of the module frame 70 occurs during manufacture (for example, when drilling the drum holes 80, or connecting the cross members 74 to the side elements 72), because the mounting plates 132 of the bearing brackets 130 can be seated on the face plates 84a and 86a, instead of directly on the side element 72a, any such distortion can be negated with respect to the rotation of the crushing drums 44 and 46.
    [0046] By mounting the mounting plates 132 to the module frame 70, each bearing bracket 130 can rotatively support the associated crushing drums 44 and 46 for rotation with respect to the module frame 70 (and the chassis 28). With particular reference to figures 7 and 8, for example, a neck 134 of each bearing support 130 can extend away from the mounting plate 132 and inwardly through the associated drum hole 80 or 82. The inner race of bearing 126 for each crusher drum 44 and 46 can be seated on the neck 134 of the associated bearing bracket 130. In certain embodiments, ring elements 124 can provide a supporting connection between the outer tracks of the bearings 126 and the body of the crushing drums 44 and 46. (It will be understood that various other connection configurations between bearings 126 and crushing drums 44 and 46 may be possible.) A ring element 124 and a bearing 126 can be mounted on the neck 134 of each bearing bracket 130 in a location that provides proper clearance between end plates 122 of crushing drums 44 and 46, and both the interior of the mounting plates 132 and the interior of the side element 72a of the air module 70 information.
    [0047] Among other advantages, the neck configuration of the bearing support 130, represented in figures 7 and 8 (and similar configurations) can also assist in maintaining the desired parallel rotation of the crushing drums 44 and 46. As can be seen in particular in figure 7, because the mounting plate 132 is affixed to the outside of the side element 72a and the neck 134 extends through the drum hole 82, the bearing 126 can be mounted relatively closely to the inside of the side element 72a. Due to this narrow gap between the bearing 126 and the side element 72a, even if the bearing support 130 is mounted on the side element 72a (for example, through the face plate 86a) in an orientation that causes the neck 134 if it deviates from the desired axis of rotation 64 for the crushing drum 46, the effect of this deviation can be significantly reduced.
    [0048] Other features can also be included. For example, with reference again to figure 7, a shoulder 136 can be provided on the inner surface of each of the mounting plates 132, which can rest against the internal diameter of the associated drum hole 80 or 82 in order to further align the bearing brackets 130 with the appropriate rotation axis 62 or 64 for the associated crushing drum 44 or 46.
    [0049] On the opposite side of the shredder drum module 42, gearbox 108 can support shredder drums 44 and 46 for rotation in several ways. As shown in figure 7, for example, a block shaft 138, supported by a bearing 140, can be screwed to the end of each of the crushing drums 44 and 46. The block shafts 138 can be engaged in several known ways (for example, example, through splined connections) with gears 142 and 144, which can be driven to rotate through the input shaft input shaft 112 (not shown in figure 7) and, in certain embodiments, several intermediate gears.
    [0050] Like face plates 84a and 86a, top and bottom face plates 84b and 86b on side element 72b can also facilitate proper alignment of the rotation axes 62 and 64 of crushing drums 44 and 46. For example, similarly to mounting plates 132 with respect to face plates 84a and 86a, cover 110 of gear box 108 can be seated firmly against face plates 84b and 86b, when gear box 108 is properly attached (for example, screwed on ) to the side element 72b. Where face plates 84b and 86b have been machined (or otherwise finished) to an appropriately flat surface that is normal to the desired parallel axes of rotation 62 and 64 for crushing drums 44 and 46, this may assist in aligning the axes of block 138 (through gearbox 108) along axes of rotation 62 and 64.
    [0051] As noted above, a fully assembled crusher drum module 42 (or several portions thereof), can be attached to chassis 28, for operation. Referring also to Figures 9 and 10, for example, the chassis 28 may also include several mounting brackets 148 or other mounting elements. In order to attach the crusher drum module 42 to the chassis, the crusher drum module 42 (for example, already completely assembled, including gearbox 108 and an associated hydraulic motor (not shown)), can be inserted through a the side openings 150 and the various mounting brackets 92 and 96 (or other display elements) of module 42, properly aligned with the mounting brackets 148 (or other display element) of the chassis 28. Appropriate mounting devices ( for example, several insulators 94 and 98) can then be engaged to secure module mounting brackets 92 and 96 to chassis mounting brackets 148 and thus to secure module 42 to chassis 28, they may include vibration, such as insulators 94 and 98. With reference also to figures 11 and 12, an example configuration of insulator 94 and an associated chassis support 148 is shown. It will be understood that insulator 98 can be configured similarly or differently than insulator 94, and that various other types of vibration damping devices may be possible.
    [0052] In the embodiment shown, the lower mounting bracket 92 includes a metal display element 160, which is screwed along one side of the element 160 to the cross element 74 of the module frame 70. The display element 160 also extends away from the cross member 74, when supported by two ribs 164, to form an interface with the chassis mounting bracket 148. The chassis bracket 148 may also include a bent metal element, supported by the ribs 158, and it can be attached to the chassis 28 in several known ways (for example, by screws or welds). The two bottom mounting brackets 92 can be configured such that they have mounting faces 156a and 156b, relatively parallel to each other, when module 42 is properly aligned within chassis 28. The mounting face 156a of the display element 160 may include a central passageway, surrounded by a mounting ring 164, integrally formed with (or otherwise affixed to) the display element 160, and the mounting face 156b of the support 148 may include a screw hole or other opening.
    [0053] The insulator 94 can be mounted on the display element 160 and can be engaged in order to generally attach the lower mounting bracket 92 to the mounting bracket 148, while also dampening the transmission of vibrations between the chassis 28 and the crusher module 42. In certain embodiments, insulator 94 may include two insulator rings 166 and 168 (for example, rubber rings) on opposite sides of mounting ring 164. Lower insulator ring 168 can be seated between mounting ring 164 and the lower mounting face 156b, and the upper insulating ring 166 can be seated between the mounting ring 164 and a movable washer 170 (or other compression element). A metal (or other) sleeve 176 may extend through rings 166 and 168 to resist shear forces on insulator 94, and a screw 172 (or other element) may extend through sleeve 176, through hole on the mounting face 156b, and the washer 170. A screw head 172a 172 can be seated on the chassis mounting bracket 148, opposite the mounting face 156b, and a screw nut 174 can be seated on the washer 170, opposite the insulator ring 166. In this way, by tightening the screw nut 174, an operator can compress the insulator rings 166 and 168 between the washer 170 and the support 148. This can boost the insulator rings 166 and 168 into the mounting ring 164 and thus attach the module bracket 92 to the chassis bracket 148. With similar (or other) connections being established between the various brackets and devices on the crusher drum module 42 and the chassis 28 (for example , among other supports 92 and 94 in the module 42 and other supports 148 in chassis 28), module 42 can thus be attached to chassis 28, for operation, and the transmission of vibrations between chassis 28 and module 42 can be appropriately dampened.
    [0054] In the various figures, and in the various examples above, insulators 94 and 98 are represented as being mainly mounted on the crusher drum module 42. It will be understood, however, that other configurations may be possible. For example, insulators 94 (or various other vibration damping devices), as well as several other types of mounting devices, can be additionally (or alternatively) mounted on chassis 28 (or on another harvester feature 20), in a way that insulators 94 and 98 (or other devices) remain with chassis 28 (or combine 20) when the crusher drum module 42 is removed. Similarly, although various components (for example, insulator rings 166 and 168, mounting ring 164, and others) can be described as exhibiting a particular geometry (for example, annular), several other configurations are possible. For example, in certain embodiments, square (or other) rubber gaskets (not shown) can be used in place of insulator rings 166 and 168 in order to properly dampen vibrations. In certain embodiments, several different rubber materials can be alternatively (or additionally) used. For example, polymer or other materials can be used to form various sealing rings or other devices. Similarly, various mechanical or other devices, such as springs, shock absorbers, dampers, and the like, can be used to dampen vibrations.
