Description

The specification relates generally to agricultural vehicles, and more particularly to a support system configured to facilitate the coupling of a harvesting device to another agricultural vehicle to form an agricultural harvester. Generally, harvesters include multiple drums distributed across the width of the harvester. Each drum is configured to harvest a row of crops as the harvester moves across a field. For example, a drum of a cotton harvester may include a rotor with spindles rotating around the rotor to separate cotton bolls from cotton bushes. Harvested crops (e.g. cotton) and other agricultural materials (e.g. hay, leaves) can be directed to a warehouse, baler or field through outlets. However, typical self-propelled harvesters can be large and/or expensive. Summary Description of the Invention In one embodiment, a method comprises connecting one or more legs of a support system to a chassis of a harvesting device, while the harvesting device is attached to and supported by one or more legs, while a power transmission group of an agricultural vehicle is attached to a chassis below the harvesting device. position and connecting the harvesting assembly to the power transmission assembly to form a harvesting machine. In one embodiment, a system configured to facilitate the assembly of a harvester includes a harvesting assembly configured to be coupled to a power transmission assembly of an agricultural vehicle to form the harvester; wherein the harvesting device includes a frame with beams extending to one side. The system also includes a support system configured to be attached to the laterally extending beam. The laterally extending beam and support system provide a lateral gap between a part of the chassis and a part of the support system; This clearance allows one wheel of the drivetrain to rotate in lateral range, allowing the drivetrain to move into a position below the harvester to facilitate setting up the harvester.

Detailed Description of the Invention One or more specific embodiments of this specification will be described below. To provide a concise description of these embodiments, not all features of an actual embodiment may be described in the specification. It must be recognized that in the development of any such actual application, as in any engineering or design project, many application-specific decisions must be made to achieve the developers' specific goals, such as compliance with system-related and business-related constraints, which may vary from one application to another. However, it should be recognized that such a development effort would be complex and time-consuming, however, it would be a procedure for those of ordinary skill to undertake design, manufacture and production who would benefit from this specification. While elements of various embodiments of this specification are set forth, the articles "a" and "said" are intended to indicate the presence of one or more elements. "Include" means that there may be additional elements. A harvester collects agricultural produce and, as the harvester moves across a farm field, separates portions of the agricultural produce into harvested crops (e.g., cotton) and other agricultural materials (e.g., straw, leaves). Harvested crops and other agricultural materials are discharged into outlets such as a harvested crop outlet and a discharge outlet, respectively. Some typical self-propelled harvesters may be large and/or expensive. Therefore, the disclosed embodiments provide a system that facilitates the conversion or modification of another agricultural or work vehicle into a harvesting machine. For example, a tractor can be used throughout the year to perform various farming operations (e.g. non-harvest operations). As the harvest season approaches, an operator (e.g. farmer) combines harvester components (e.g. one or more drums, a blower, a tank, a cabin) to specific tractor components (for example, the tractor chassis, which carries wheels, an engine, a transmission, and a heating and ventilation (HVAC) system). When the harvest season ends, the operator can separate the harvester components from the tractor components and the tractor can be reused to carry out various farming operations. In some embodiments, the system includes a support system (e.g., foot system) configured to support the harvester components in an elevated position to enable the operator to move (e.g., take) the tractor components into a position vertically below the harvester components. Once the tractor components have reached the appropriate position vertically below the harvester components, the support system can adjust the vertical position of the harvester components relative to the tractor components (e.g. leveling and/or lowering the harvester), thereby clearing the farmland to collect crops and carry out harvesting operations. It allows the operator to connect harvester components to tractor components (e.g. via couplers, wires, cables, quick couplers) to create a harvester configured to move along the tractor. Advantageously, the disclosed arrangements can facilitate the effective installation of a relatively small and/or low-cost harvester that also provides high harvesting capacity and/or increased yield of harvested crops (compared, for example, to self-propelled harvesters), for example, compared to harvesting crops by hand. The support system advantageously described can be used to support harvester components when disassembling the harvester to facilitate separation of harvester components from tractor components. In some embodiments, the support system disclosed may be used to store harvester components (e.g., partially or fully assembled) when the harvester components are not connected to tractor components (e.g., at other times of the year or outside the harvest season). While this specification illustrates embodiments of a harvester that include harvesting components and tractor components for ease of discussion, it should be understood that the harvester may include components of any of a variety of agricultural or work vehicles, such as trucks or the like. For example, the support system can be used to facilitate the attachment of harvester components to components of a truck to form a harvester. Furthermore, the support system can be used to facilitate the installation of any of a variety of agricultural or business vehicles. For example, the support system can be used to facilitate the coupling of sprayer components to components of a tractor to form a sprayer. Thus, the disclosed support system can be configured to facilitate the interconnection of components of various types of agricultural or business vehicles to form a particular agricultural or business vehicle. Turning now to the drawings, Figure 1 is a perspective view of an embodiment of a harvester 10 (e.g., a tractor-mounted harvester or a modified tractor) configured to harvest rows of a crop in an agricultural field. To facilitate discussion, the harvester 10 and associated components can be described with reference to a longitudinal axis or direction 12, a vertical axis or direction 14, and a sideways axis or direction 16. As shown, the harvester 10 consists of a plurality of drums 18 that use one or more rotors to separate harvested crops (e.g., cotton or other agricultural produce) from other agricultural materials (e.g., straw, leaves, stems, residues) (e.g., harvest includes heads). The harvester (10) includes an air system that includes a blower (20) (e.g., fan) configured to blow air to direct the harvested products to a storage (24) (e.g., basket or baler) through one or more channels (22). may contain. In some embodiments, the tank 24 may be configured to move (e.g., rotate or cycle) to transfer harvested crops outside the tank 24 (e.g., to another container or agricultural field). In some embodiments, other agricultural materials may be deposited on the agricultural field below and/or behind the harvester (10). In some embodiments, the harvester 10 may include a cab 32 configured to transport or accommodate an operator. It should be noted that the cab 32 may be an enclosed cab (e.g., environmentally controlled cab) as shown, or the cab 32 may be a platform on which the operator may, for example, sit or stand (e.g., an open or non-enclosed platform). In the illustrated embodiment, the cab 32 includes one or more operator interfaces that enable the operator to monitor and/or control various functions of the harvester 10, such as ground speed, steering angle, transmission range and/or gears, HVAC system operation, or the like. and/or input device (34) (e.g. switch, button, light, display, steering wheel, gear lever). As shown, the tank (24) and cabin (32) are carried on a chassis (36) (e.g. harvester chassis or frame). Various other components (e.g., drums 18 , blower 20 , one or more ducts 22 ) may be carried by and/or connected to the chassis 36 to form the harvester 10 . In the illustrated embodiment, the chassis 36 includes a cover assembly configured to cover (e.g., surround or protect) various components carried on a chassis 40 (e.g., tractor frame or undercarriage), such as an engine, a transmission, an HVAC system, and a radiator. Supports or includes (38) (e.g. cage assembly). In practice, the harvester (10) can be driven in the direction of progress (42) across the agricultural field using the front wheels (44) and rear wheels (46). As discussed above, the harvester 10 may include harvester components and tractor components. For example, in the embodiment shown, the front wheels 44, the rear wheels 42, the chassis 40 and the various components carried on the chassis 40, such as the engine, transmission, HVAC system and/or radiator, a tractor (e.g. an unmodified tractor). It may form a tractor assembly (50) (e.g. power transmission assembly) which may be connected to other tractor components (e.g. tractor body, tractor cab or the like) to form devices (34), chassis (36), and/or cover assembly (38), a part of a harvesting assembly (52) (e.g., harvester kit or conversion kit) that can be connected to the tractor assembly (50) to form or install the harvesting machine (10). it could be. Therefore, at certain times of the year, the operator may use tractor assembly 50 as part of a tractor to carry out various agricultural tasks. However, during a harvest season, the operator may separate the tractor assembly 50 from other tractor components, and then the operator may combine the tractor assembly 50 with the harvesting assembly 52 to set up the harvester 10 to carry out harvesting operations. At the conclusion of the harvest season, the operator can separate the tractor assembly 50 from the harvesting assembly 52 and then reassemble the tractor components of the tractor assembly 50 to form the tractor to continue various agricultural operations. In certain embodiments, a support system 60 (e.g., foot system) may be connected to the harvesting device 52 to facilitate coupling of the harvesting device 52 to the tractor device 50. For example, in order to enable the operator to insert (e.g. take) the tractor assembly (50) to the position vertically below the harvesting assembly (52), for example in the direction of the arrow (62) (which is aligned with the forward direction (42), the support system (60) It can support the assembly (52) in an elevated position. After the tractor assembly (50) reaches the appropriate position vertically below the harvesting assembly (52), the operator can connect the harvesting assembly (52) to the tractor assembly (50) to form the harvesting machine (10). In some embodiments, the support system (60) may adjust the vertical position of the harvesting assembly (52) to bring the harvesting assembly (52) to the same level as the tractor assembly (50) and/or lower it towards it, allowing the operator to move the harvester (52) to the same level as the tractor assembly (50). It allows the harvesting device (52) to be connected to the tractor device (50). In some embodiments, the support system (60) can be used to support the harvesting device (52) while the harvester (10) is being disassembled, to facilitate the separation of the harvesting device (52) from the tractor device (50). For example, to enable the operator to move (e.g. take) the tractor assembly (50) in the opposite direction to the arrow (62) in order to remove the tractor assembly (50) from the position shown below the harvesting assembly (52), the support system (60) is used to remove the harvesting assembly (52). ) can support in an elevated position. In some embodiments, in practice, the operator may connect the support system (60) to the harvesting assembly (52), then detach the harvesting assembly (52) from the tractor assembly (50), and then lift the support system (60) to raise the harvesting assembly (52) relative to the tractor assembly (50). ) can be adjusted, thus allowing the operator to move the tractor assembly (50) away from the harvesting assembly (52). In some embodiments, the support system 60 may be used to support the harvesting device 52 (e.g., partially or fully assembled) when the harvesting device 52 is not connected to the tractor device 48 (e.g., at other times of the year or outside the harvest season). It should be noted that it may have any suitable number of drums 18, such as more drums 18. It should also be noted that the harvester 10 may include tracks in place of the front wheels 42 and/or the rear wheels 44. Figure 2 is a perspective view of the tractor assembly 50 and the harvesting assembly 52, which can be connected together to form the harvesting machine 10, in accordance with an embodiment of this specification. The tractor assembly (50) may include front wheels (44), rear wheels (46), chassis (40), and/or various other components carried on the chassis (40). For example, the tractor assembly 50 may include power transmission components such as an engine 70, a transmission 72, and/or other components that transfer power from the engine 70 to the axles to drive the rotation of the front wheels 44 and the rear wheels 46. . In some embodiments, tractor assembly 50 may include various other components such as an HVAC system 74 (e.g., compressor and condenser) and/or a radiator 76. When the tractor assembly (50) is not connected to the harvesting assembly (52), the tractor assembly (50) is used to form a tractor (82) (e.g., an unmodified tractor) and to use the tractor (82) to carry out various agricultural operations (e.g., non-harvest operations). It may be coupled to various other tractor components 80, such as a tractor hood, tractor cab, tractor input devices, or the like, to allow movement in the forward travel direction 84. As shown, the harvesting assembly 52 includes, among other components, drums 18, blower 20, one or more ducts 22, tank 24, cab 32, input devices 34, chassis 36 ) and cover assembly (38). The harvesting device (52) can be connected to the tractor device (50) (e.g., via coupling elements) to form the harvesting machine (10) for moving in the forward direction (42) across the agricultural field. In some embodiments, the forward movement direction (84) of the tractor (82) is opposite to the forward direction (42) of the harvester (10) (i.e. the front wheels (44) of the harvester (10) are the rear wheels of the tractor (82). The harvesting assembly 52 may be connected to the tractor assembly 50 through any of several processes or steps. For example, in some embodiments, the harvesting assembly 52 may be partially assembled or (as shown for example) fully assembled and then connected or mounted to the tractor assembly 50 to form the harvesting machine 10. In some embodiments, components of the harvesting assembly 52 may be connected to the tractor assembly 50 individually and/or sequentially. As discussed in more detail below, the support system 60 is configured to facilitate the attachment of the harvesting assembly 52 to the tractor assembly 48 to form the harvesting machine 10. Figure 3 is a perspective view of an embodiment of the support system (60) attached to the chassis (36) of the harvesting device (52). As shown, the support system 60 includes a first front leg 62 and a second front leg 64, which may be part of a front leg assembly 66 configured to support a front portion of the harvesting device 52. The illustrated support system 60 includes a first rear leg 72 and a second rear leg 74, which may be part of a rear leg assembly 76 configured to support a rear portion of the harvesting assembly 52. When connected to the harvesting device (52), the first front leg (62) and the second front leg (64) are positioned on opposite sides of the harvesting device (52), and the first rear leg (72) and the second rear leg (74) are positioned on opposite sides of the harvesting device (52). are positioned on opposite sides. In some embodiments, some or all of the legs (62, 64, 72, 74) may be connected to each other to add stability to the support system (60). For example, the legs 62 and 64 can be connected to each other and/or the legs 72 and 74 can be connected to each other. In some embodiments, a beam (e.g., adjustable beam) is used to connect two or more legs (62, 64, 72, 74) together, and a beam (e.g., adjustable beam) is used to connect the respective parts of the two or more legs (62, 64, 72, 74) (e.g., a base section, lower It can be mounted or connected between the part or the person in contact with the ground. (e.g. a lifting or drive system) and a support structure with a beam section 84; The beam section includes a vertical beam (86) (e.g., vertically extending beam), a lateral beam (88) (e.g., laterally extending beam), and/or a support beam (86) extending between the vertical beam (86) and the lateral beam (88). 89) may contain. The adjustable portion 82 may be configured to adjust a vertical position of the beam portion 84 relative to the base portion 80 which may be supported on the ground and contacts it. In the illustrated embodiment, the adjustable part (82) is connected to the beam part (84), for example, to a lower end part of the vertical beam (86) (for example, by means of fastening element and/or welding) and through a hole (94) in a plate (94) of the base part (80). 92) includes a mechanical jack device having a threaded rod 90 extending (e.g. through a through hole with corresponding threads). In order to facilitate the rotation of the threaded rod (90), an arm (96) (e.g. a rod extending laterally) extends from the threaded rod (90) and the rotation of the threaded rod (90) causes the threaded rod (90) to meet the corresponding hole (92) in the plate (94). It causes movement along the incoming teeth and drives the connected beam section (84) vertically relative to the base section (90). It should be noted that the adjustable part 82 may have any shape suitable for adjusting the vertical position of the beam part 84 relative to the base part 90. For example, the adjustable portion 82 may include a hydraulically operated jack, a pneumatically operated jack, or the like. In some embodiments, power to operate the adjustable portion may be drawn from the power transmission assembly (e.g., engine) of the tractor assembly 48. In some embodiments, the first front leg (62) and the second front leg (64) are configured to be connected to the laterally extending beam (100) of the chassis (36), and the first rear leg (72) and the second rear leg (74) are configured to connect to the laterally extending beam (100) of the chassis (36). ) is configured to be connected to the respective vertically extending beams (102). It should be understood that supports can be used to support the harvesting device 52. For example, two additional legs can be positioned between the front leg assembly (66) and the rear foot assembly (76) along the longitudinal axis (12) to be connected to an intermediate part of the chassis (36). In some embodiments, an operator connects the first front leg (62) and the second front leg (64) to the laterally extending beam (100) of the chassis (36) (e.g., through tight fitting and/or fastening elements) and attaches the first rear leg (72). and by connecting the second rear leg (74) to the respective vertically extending beams (102) of the chassis (36) (e.g. by means of plates and/or fasteners), the harvester (10) of Figure 1 can be installed or formed. In some embodiments, the operator may adjust the adjustable portions 82 to adjust a vertical position of the beam portion 84 relative to the base portion 80, thereby adjusting a vertical position of the chassis 36 relative to the ground. While the harvesting device (52) is connected to the legs (62, 64, 72, 74) of the support system (60) and positioned in a suitable vertical position relative to the ground, the operator moves the tractor device (50) (Figure 2) to a position under the harvesting device (52). can move. For example, in some embodiments, the operator may position the tractor assembly 50 behind the harvesting assembly 52, moving the front wheels 44 and rear wheels 46 of the tractor assembly 50 at defined lateral intervals 104 (e.g., along the lateral axis 16). gap or gap) and then apply a force to the tractor assembly (50) in the direction of the arrow (62) to drive the tractor assembly (50) towards the position below the harvesting assembly (52) (for example, driving it on the wheels (44, 46). It should be understood that some portions of the chassis 36, including the various rear sections 106, may be added to the chassis 36 after moving the tractor assembly 50 into position below the harvesting assembly 52, thus providing additional space and/or visibility during the operation. Furthermore, it should be understood that various components of the harvesting device 52 may be connected to the chassis 36 at any point during the assembly or installation of the harvesting machine 10. For example, the tank (24), cabin (32), cover assembly (38) and/or other components may be added to the harvesting assembly (52) before positioning the legs of the support system (60) under the assembly (52). It should also be understood that in some embodiments, various components may be adapted to allow the operator to move the tractor assembly 50 in a direction opposite the arrow 62 to position the tractor assembly 50 below the harvesting assembly 52. As noted above, in some embodiments, the support system 60 may be used to support the harvesting assembly 52 while the harvester 10 is being disassembled to facilitate separation of the harvesting assembly 52 from the tractor assembly 50. In some embodiments, an operator connects the first front leg (62) and the second front leg (64) to the laterally extending beam (100) of the chassis (36) (e.g., through tight fitting and/or fastening elements) and attaches the first rear leg (72). and by connecting the second rear leg (74) to the respective vertically extending beams (102) (e.g. by means of plates and/or fastening elements) of the chassis (36), while the harvester (10) of Figure 1 is fastened (74), the operator can, for example, remove the fastening elements and/or separate the tractor assembly (50) (Figure 2) from the harvesting assembly (52) by separating various wires, cables or the like. In some embodiments, after separating the tractor assembly (50) from the harvesting assembly (52), the operator can adjust the adjustable portions (82) to adjust a vertical position of the beam portion (84) relative to the base portion (80), thereby adjusting a vertical position of the chassis (36) to the ground. settings accordingly. While the harvesting device (52) is connected to the legs (62, 64, 72, 74) of the support system (60) and positioned in a suitable vertical position relative to the ground and the tractor device (50), the operator removes the tractor device (50) (Figure 2) from the harvesting device. (52) can move it far. For example, in some embodiments, the operator may apply a force to the tractor assembly 50 in a direction opposite to the arrow 62 to drive the tractor assembly 50 to a position behind the harvesting assembly 52 (e.g., on wheels 44, 46). In some embodiments, the support system 60, when the harvesting device 52 is not connected to the tractor device 48 (e.g., at other times of the year or outside the harvest season), supports the harvesting device 52 (e.g., partially or fully assembled) as shown vertically throughout the period. can hold it in an elevated position. In some embodiments, the legs 62, 64, 72, 74 move the harvesting assembly 52 vertically (e.g., support block) to maintain it in a vertically lowered position for an extended period of time and/or to carry it across the ground or other support structure (e.g., support block). 14) can lower. It should be understood that some portions of the chassis 36, including various rear sections 106, may be detached from the chassis 36 before moving the tractor assembly 50 away from the harvesting assembly 52, thus providing additional space and/or visibility during the operation. Furthermore, it should be understood that various other components of the harvesting assembly 52 may be separated from the chassis 36 at any point during the disassembly of the harvester 10. For example, the tank (24), cabin (32), cover assembly (38) and/or other components may be separated from the harvesting assembly (52) before the support system (60) can be moved away from the legs assembly (52). It should also be understood that in some embodiments, various components may be adapted to allow the operator to move the tractor assembly 50 in the direction of arrow 62 while the harvester 10 is being disassembled to move the tractor assembly 50 to a position in front of the harvesting assembly 52 . Figure 4 is a front view of an embodiment of the support system 60 attached to the chassis 36 of the harvesting device 52. As shown, the first front leg (62) and the second front leg (64) are connected to the laterally extending beam (100) of the chassis (36) of the harvesting device (52). In the illustrated embodiment, the laterally extending beam 100 is a one-piece beam extending laterally between the first front leg 62 and the second front leg 64 and contacting both, although other configurations are envisaged. For example, the laterally extending beam 100 may be a multi-piece beam. In the illustrated embodiment, the laterally extending beam (100) of the chassis (36) includes a first hole (110) at a first end (112) and a second hole (114) at a second end (116). The laterally extending beam 100 may be a hollow beam (e.g., ring or tubular structure), or the laterally extending beam 100 may be inserted into the respective lateral ribs 88 of the first forelimb 62 and the second forelimb 64. It may contain hollow parts (1 18) (e.g. ring or tubular parts) that allow it to receive and support them. Referring to the first front leg 62, the lateral beam 88 extends laterally inwardly extending laterally into the chassis 36. In the illustrated embodiment, a first end portion 120 of the lateral beam 88 is connected (e.g. by means of fasteners and/or welding seams) to the vertical beam 86, and a second end portion 122 of the lateral beam 88 is connected to the laterally extending beam. It is positioned inside (100). The lateral beam 88 may extend for any distance in the laterally extending beam 100 (e.g., along the lateral axis 16). In some embodiments, one or more fasteners may be used to connect the lateral beam (88) to the laterally extending beam (100). For example, one or more pins 130 may be inserted through aligned holes formed in the lateral beam 88 and the laterally extending beam 100 (e.g., in a direction perpendicular to the axis 16) so that the lateral beam 88 can be inserted sideways. Its movement (e.g. sideways movement) relative to the beam (100) extending laterally is prevented and the beam 588 is kept within the beam (100) extending laterally. It should be understood that various fastening elements such as threaded fastening elements (e.g. bolts or screws), clamps or clamps can be used in connecting the lateral beam (88) to the laterally extending beam (100). As shown, the second front leg (64) may have the same features and may engage the second hole (114) at the second end (116) of the laterally extending beam (100) in the same way. For example, with reference to the first front leg (62), the sideways gap (104) is in the sideways direction (16) between a part of the chassis (36) of the harvesting device (52) and the vertical beam (86) of the beam part (84) of the first front leg (62). ) stretches. As mentioned above, the sideways spaces (104) allow the wheels of the tractor assembly (50) (Figure 2) (e.g. front wheels 44) and/or rear wheels 46 ([Figure 2])) to rotate through the sideways gaps (104). so that the tractor assembly (50) can be moved to a position below the harvesting assembly (52) to facilitate the installation of the harvesting machine (10). Figure 5 is a perspective view of an embodiment of a portion of the support system (60) attached to the chassis (36) of the harvesting device (52). As shown, the first rear leg (72) and the second rear leg (74) are connected to the respective vertically extending beams (102) of the chassis (36) of the harvesting device (52). With reference to the first rear leg (72), a first end portion (140) of the lateral beam (88) is connected (e.g. by means of fasteners and/or welding seams) to the vertical beam (86) and a second end portion of the lateral beam (88). (142) is connected to a plate (144) (for example, by means of fasteners and/or welding seams). In some embodiments, the plate (144) may be connected to a corresponding plate (146) (e.g., via fasteners (148)) which is connected to the relevant vertically extending beam (102) (e.g., via fasteners and/or welded seams) of the chassis (36). The second rear leg (74) may include the same features and may be connected to the vertically extending beam (102) of the chassis (36) in the same way. It should be understood that any of the legs shown and described herein may be attached to the chassis 36 from any suitable location by any suitable technique. For example, the first front leg (62) and/or the second front leg (64) can be connected to the chassis (36) by means of plates, as shown in Figure 5, and/or the first rear leg (72) and/or the second rear leg (74), as shown in Figure 5. It can be connected to the chassis (36) via tight fit and/or pins as shown in 4. Fig. 6 is a flow diagram of an embodiment of a method 200 in which the support system 60 is used to connect the harvesting assembly 52 to the tractor assembly 50 to form the harvesting machine 10, and Fig. 7 is a flow chart of the harvester to disassemble the harvesting machine 10. is a flow diagram of one embodiment of a method (220) in which the support system (60) is used to separate the assembly (42) from the tractor assembly (50). The methods 200, 220 include various stages represented by blocks. Although flowcharts show the steps in a specific order, it should be understood that the steps can be carried out in any convenient order, some steps can be skipped, and certain steps can be carried out simultaneously where appropriate. It should be understood that the various features described above with respect to Figure 1-5 can be combined with and/or used in conjunction with the steps of the methods 200, 220. While the methods 200, 220 are explained with reference to the harvester 10 for ease of discussion, it should be understood that the steps of the methods 200, 220 can be applied to various types of agricultural and work equipment. Referring to Fig. 6, at step 202 an operator can connect the support system 60 to the chassis 3 6 of the harvesting device. For example, the operator can connect the first front leg (62) and the second front leg (64) to the laterally extending beam (100) of the chassis (36) and attach the first rear leg (72) and the second rear leg (74) to the corresponding vertical beam of the chassis (36). It can be connected to the beams (102) extending as follows. As discussed above with reference to FIG. can be inserted. In some embodiments, one or more fastening elements (e.g. pins (130)) may be used to connect the first front leg (62) and the second front leg (64) to the laterally extending beam (100). Furthermore, as discussed above with respect to Figure 5, in some embodiments, the lateral beam 88 of the first rear leg 72 and the lateral beam 88 of the second rear leg 74 are attached to the respective plates (e.g. by means of fasteners or welding seams). 144) can be connected; These plates can then be connected to the corresponding corresponding plates 146 (e.g. via fasteners 148) which are then connected via the chassis 36 (e.g. fasteners or weld seams). At step 204, the operator can adjust a vertical position of the chassis 36 to align with the ground. For example, while the first front leg (62) is connected to the chassis (36) of the harvesting device (52), the operator can rotate the arm (96) connected to the threaded rod (90) extending from the beam part (84) of the first front leg (62), so that the gear rod (90) ) causes the base part (80) to advance along the corresponding teeth in the hole (92) in the plate (94) and causes the attached chassis (36) to move vertically (e.g. rise) relative to the ground, while being attached and positioned in a suitable vertical position relative to the ground. The operator can move the tractor assembly (50) to a position below the harvesting assembly (52). For example, in some embodiments, the operator may position the tractor assembly 50 behind the harvesting assembly 52, align the front wheels 44 and rear wheels 46 of the tractor assembly 50 with defined lateral spacings 104, and then position the tractor assembly 50 ) can apply a force to the tractor assembly (50) in the direction of the arrow (62) in order to drive it (for example, to drive it on the wheels (44, 46)) towards the position under the harvesting assembly (52). In some embodiments, the tractor assembly 50 may be removed or separated from other tractor components 80 before being moved into position below the harvesting assembly 52. At step 208, the operator can adjust a vertical position of the chassis (36) relative to the ground and/or adjust the adjustable portions (82) to facilitate the coupling of the harvesting device (52) to the tractor device (50). For example, the operator is supported by the adjustable parts (82), the chassis of the harvesting device (36) and the chassis (40) of the tractor device (50) (for example, a front axle carrying the front wheels (44) and/or a rear axle carrying the rear wheels (46)). can adjust until it touches or reaches a position. Adjustable portions 82 may be operated as described above with respect to step 204 to raise or lower chassis 36 (or portions thereof) relative to the ground and tractor hitch 50. At step 210, the operator can connect the harvesting assembly (52) to the tractor assembly (50) to form the harvesting machine (10). For example, the operator may apply fasteners (e.g., bolts, screws, pins, clamps, clamps) and/or connect various wires or cables (e.g., quick couplers) to connect the harvesting assembly 52 to the tractor assembly 50 to form the harvester 10 . As stated above, various components of the harvesting device (52) (for example, drums (18), one or more channels (20), tank (24), cabin (32)), are attached to the harvesting device (52) during the installation of the harvesting machine (10). can be connected at any point. In order to enable the harvester (10) to carry out the harvesting operations (for example, removing the pins (130), removing the first front leg (62) and the second front leg (64) from the laterally extending beam (100) and removing the first rear leg (72) and the second By removing the corresponding plates of the rear leg (74) from the corresponding plates (46) of the chassis (36), at step 222 with reference to Fig. 7, an operator can connect the support system (60) to the chassis (3 6) of the harvesting device. For example, the operator may attach the first front leg 62 and the second front leg 64 to the laterally extending beam 100 of the chassis 36 and attach the first rear leg 72 and the second rear leg 74, e.g. according to the method of Fig. 6 (200) may be connected to the respective vertically extending beams (102) of the chassis (36), as explained above in connection with step 202. and while being carried by it, the operator may separate the tractor assembly (50) from the harvesting assembly (52), for example by removing fastening elements and/or disconnecting various wires, cables or the like. At step 226, after separating the tractor assembly 50 from the harvesting assembly 52, the operator can adjust the adjustable portions 82 to adjust a vertical position of the chassis 36 relative to the ground and relative to the tractor assembly 50. For example, the adjustable portions 82 may be operated as described above with respect to step 204 of the method 200 of Fig. 6 to raise the chassis 36 (or portions thereof) relative to the ground and relative to the tractor assembly 50 . and positioned in a suitable vertical position relative to the ground, the operator can move the tractor assembly (50) away from the harvesting assembly (52). For example, in some embodiments, the operator may apply a force to the tractor assembly 50 in a direction opposite to the arrow 62 to drive the tractor assembly 50 to a position behind the harvesting assembly 52 (e.g., on wheels 44, 46). In some embodiments, after the tractor assembly (50) is moved away from the harvesting assembly (52) to set up the tractor (82), the support system (60) is attached to the other tractor in Step 230 (e.g., at other times of the year or outside the harvest season) the harvesting assembly (52). It can support the harvesting device (52) when it is not connected to the tractor device (48) (e.g., partially or fully assembled). It can hold it in a vertically elevated position. Although only some features of the specification are shown and explained here, many modifications and changes will become apparent to those skilled in the art. It should therefore be understood that the accompanying claims are intended to cover all such modifications and changes that fall within the scope of the true spirit of the specification.TR
