    [001] This invention relates to a platform for a combine where the platform includes gauging wheels on the ground and particularly that includes a driver-operated control system to control the cutting height and the platform angle. BACKGROUND OF THE INVENTION
    [002] Combine platforms are mounted in the harvester feeder housing to cut a permanent crop and feed the crop to the feeder housing for transport within the harvester for processing. Such platforms typically include a mower knife cutter bar to cut the permanent crop, a convergence system to transport the crop inward along the platform to the feeder housing and a reel to sweep the crop over the cutter bar in the convergence system.
    [003] In some cases, platforms include gauge wheels at the outer ends to partially support the platform and a mounting arrangement for the platform in the feeder housing that supports the platform at a required height. In some cases, the mounting arrangement includes an adapter that provides a floating action of the platform with respect to the feed housing. In other cases, the height of the platform in the feeder housing is controlled by lifting cylinders that locate the platform at the required height as determined by the height of the gauge wheels.
    [004] The gauge wheels can be adjusted so that the cutting bar can rest on the ground and float on the ground in a cutting action or can be located at a predetermined cutting height in relation to the ground. The driver must therefore be able to control the cutting height of the mower knife from the ground and this can typically be adjusted on the moving base.
    [005] An additional important factor to be controlled by the combine driver is the angle of the platform to the ground during the cutting action. The platform angle is an angle around a transverse axis so that the platform is placed backwards at a low angle in some cutting conditions where the crop is standing upwards for harvesting and is tilted forward to a much wider angle aggressive for some other conditions. The forward angle acts to move the wheel forward and present it more aggressively over the harvest. It is well known that the angle of inclination of the platform must be adjusted on a moving base so that the driver can accommodate different harvest conditions, for example, where the harvest is deposited and must be lifted more vigorously. SUMMARY OF THE INVENTION
    [006] It is an objective of the invention to provide a platform for a harvest where the platform includes gauging wheels on the ground and particularly that includes a driver-operated control system to control the cutting height and platform angle.
    [007] According to the invention a platform assembly is provided for attachment to a harvester feeder housing for movement in a forward working direction through the field carrying a permanent crop to be harvested, the platform assembly comprising: a platform comprising: a platform frame; a mower cutting bar loaded through a front of the platform frame to cut the permanent crop; a reel to load the harvest on the cutter bar; a harvest transport device for transporting the harvest inward from the ends of the platform to a collection location for feeding to the combine; a mounting arrangement for mounting the platform frame to the combine feeder housing; first and second ground gauge wheels on the platform frame on each side of the feeder housing; the ground gauge wheels being mounted on the platform frame in a position spaced behind the cutter bar; first and second adjustable connections to adjust the height of the first and second gauge wheels respectively with respect to the platform frame in response to a height entry; an angle adjustment element for tilting the platform frame back and forth about a transverse axis in the forward working direction with respect to said mounting arrangement in response to an angle entry; a driver-operated control system that includes a driver interface arranged for driver input of: a first input acting to adjust a required height of the cutter bar from the ground; and a second entry acting to adjust a required angle value of the platform with respect to the ground; the control system including a program responsive to the first and second inputs to generate said height input for said first and second adjustable connections and said angle input to said angle adjustment element to automatically obtain said adjustment of a value of a required height of the cutter bar from the ground and said adjustment of a required angle value of the platform with respect to the ground.
    [008] Preferably, a height adjustment arrangement is provided to adjust the platform height with respect to the harvester and the height of the platform with respect to the harvester is adjusted in association with the height of the first and second wheels. This can be controlled automatically by the combine where the height of the platform in relation to the combine automatically retains the height of the platform in order to keep part of the platform in the feeder housing at a height required to match the height on the gauge wheels.
    [009] The platform can be a rigid platform having the ability to flex or it can be a three-part type platform with a central section and two wing sections where each wing section is flexibly coupled to the central section. In addition, it can also be used with a platform of the type where the cutter bar flexes with respect to the platform frame to accommodate changes in soil contour.
    [010] Preferably the height of the platform in relation to the combine is controlled by raising and lowering the feed housing.
    [011] Preferably, an adapter is provided arranged to be mounted in the feeder housing that supports the platform in the feeder housing including a harvest transfer arrangement for carrying out the harvest material through the adapter in the feeder housing. However, the platform can also be directly mounted on the feeder housing without using a separate adapter.
    [012] Preferably, a float suspension system is provided to load the platform into the feeder housing. This can be fixed directly between the platform and the feeder housing or on the adapter. Alternatively, the position of the platform in the feeder housing may be non-floating, that is, it may be fixed or it may be movable by actuators such as hydraulic cylinders that do not provide any floating action.
    [013] When a floating support is used, the floating suspension system is preferably arranged so that a larger part of the platform weight, such as up to 90%, is loaded in the feeder housing and a smaller part is loaded on the wheels of gauge. Such a floating suspension system can be adjustable so as to adjust a required proportion of the weight of the platform that is loaded in the feeder housing with respect to a proportion of the weight of the platform that is loaded on the gauge wheels.
    [014] In a preferred example, a float sensor is provided to detect a float distance from the platform with respect to a fixed point with respect to the feeder housing and to generate a signal indicating the same and a height control system of automatic platform arranged to raise and lower the feeder housing in response to the buoyancy sensor signal in order to try to maintain the buoyancy distance at a required setpoint. This acts to keep the platform part in the feeder housing at the required height while keeping the floating force constant.
    [015] Typically, the platform frame includes a top main beam and a plurality of branches hanging from the type main beam to load the crop transport system and the cutter bar and gauge wheels are mounted so that extend to a position behind the legs.
    [016] Preferably the gauge wheels are mounted on the platform frame so that, when adjusted to the required position, the gauge wheels are fixed with respect to the platform frame substantially without any floating suspension movement with respect to it . However, they can also be free to float if required. That is, the gauge wheels can be either fixed or suspended. In the mode described here, there is no floating suspension movement. This is not necessary. Gauge wheels will typically have a suspension system that can be provided by a hydraulic accumulator in the hydraulic system or could be mechanical springs. Thus, the gauge wheels will operate substantially without any suspension.
    [017] Preferably, the first and second connections comprise a hydraulic cylinder that can act directly on a lever carrying the wheel that extends backwards from the frame. However, other connections and actuators such as electric actuators can be used.
    [018] Preferably, the driver interface comprises a touch screen or other screen and control button interface mounted on a combine cab. This can either be a separate control system independent of a control system for the combine or it can be integrated with a control system for the combine. The system can use a touch screen, but the cost often requires a cheaper screen that uses buttons on the sides and a rotating input, etc. the basic idea is that a provision is provided to provide operator or feedback information (the screen) and a means for it to control inputs, which could be a touch screen or various buttons and keys, etc.
    [019] Preferably, the driver interface includes a third input acting to adjust a required speed value of the harvest transport device particularly where the harvest transport device includes a rubberized tarpaulin.
    [020] The invention also provides a harvester comprising a harvesting machine for processing cut harvest material, a harvesting machine feeder housing for feeding the cut harvest at a harvesting machine inlet; and a platform assembly of the type defined by any of the above paragraphs.

    [022] In the drawings, identical reference characters indicate corresponding parts in the different figures. DETAILED DESCRIPTION
    [023] A combine is shown is shown schematically at 10 and includes soil wheels 11, a main housing 12 containing the harvest processing devices, a cab 13 for the operator and a feeder housing 14 for receiving the harvest material and feed it into the housing for processing. The details of the combine are well known to a person skilled in the art so that no detail is necessary for an understanding of this invention.
    [024] The feeder housing 14 is mounted on the housing in a manner that allows it to be raised and lowered as indicated in 14A to raise the loaded platform in front of the combine. For example, the feeder housing includes cylinders 15 that raise and lower the front end 16 of the feeder housing.
    [025] A platform assembly 20 is attached to the feeder housing 14 of the combine 10 and includes a platform 21 and an adapter 22 that secures the platform to the feeder housing. Adapter 22 is provided to control the crop feed by a conveyor 22A within the feeder housing 14 and provide spring lifting force 22B and lift arms 22C from a suspension system 30 onto the platform to load it onto. front in front of the feeder housing.
    [026] The platform in general is of a conventional construction well known to a person skilled in the art and the larger components include a cutter bar 23 to cut the permanent crop and a crop transport device defined by a pair of rubberized plies 24 and 25 to transport the permanent crop inward from the ends of the platform to a collection location 26 on the conveyor 22A to feed into the combine.
    [027] The platform includes two gauge wheels engaging the ground 27 and 27A on the platform one on each side of adapter 22. The number of wheels can be increased in some cases so that double wheels are used or wheels on an axle, but in general the wheels act to support the platform on each side of the support from the adapter 22.
    [028] Each 27, 27A gauge wheel is mounted on the platform for adjustment movement up and down from a position of the gauge wheel with respect to the platform to control the height of the 21A frame (Figure 3) from the platform. ground. The platform frame 21A includes a main crossbeam 21B and several hanging branches 21C that connect in forward extending arms 21D carrying the conveyors 24, 25 and the cutter bar 23. Thus, in the example shown, the wheel 27 is mounted on a pivot arm 28 pivotally mounted on the platform frame at a pivot point 21E on the arm 21D so that the arm projects backwards from the rear of the frame with the wheel 27 at the rear end so that the wheel is loaded on an axle 27B behind the leg 21C. The arm 28 is fixed to the frame by an adjustable connection which is typically a cylinder 29 operable by a control described hereinafter arranged to be located in the harvester cab 13 to adjust the position of the gauge wheel with respect to the platform to a required position of in order to adjust the cutting height of the frame 21A from the ground.
    [029] The gauge wheels 27 and 27A are attached to the cylinders 29 which are attached to the frame 21A so that the wheels are mounted on the platform so that, when adjusted in the required position, the gauge wheels are attached with respect to the frame platform substantially without any suspension float movement with respect to it. Thus, there is preferably no permitted spring or suspension movement and the wheel is rigid in the frame.
    [030] The connection between the adapter and the platform shown in Figure 2 includes a suspension system 30 with a central top connection 2 and two side suspension arms 22C for loading the platform onto the adapter. As is well known, the suspension arrangement allows for pivoting movement side by side of the platform with respect to the adapter as well as the vertical floating movement of the platform. Thus, the suspension arms 22C are connected to springs 22B that have a spring force that can be adjusted to vary the lifting force applied to the platform from the adapter.
    [031] Thus, the suspension system is adjustable in order to adjust a required proportion of the weight of the platform that is loaded in the feeder housing 14 with respect to a proportion of the weight of the platform that is loaded on the 76 gauge wheels.
    [032] The springs 22B of the suspension system are arranged so that a larger part of the platform weight is supported in the feeder housing 14 and a smaller part is supported in the 27 gauge wheels and typically the proportion of the weight that is supported in the feeder housing is on the order of 90%.
    [033] The suspension can be arranged so that the upward movement of the feeder housing acts to increase a lifting force on the platform and downward movement of the feeder housing acts to decrease the lifting force on the platform and / or so that the upward movement of the feeder housing acts to reduce the separation between the platform and the adapter and the downward movement of the feeder housing acts to increase the separation between the platform and the adapter, although these may not occur depending on the mechanical arrangement or may not occur throughout the range of motion.
    [034] A bottom stop 28 is provided that is arranged to limit the downward movement of the platform with respect to the adapter 22 and a float sensor 39 is provided to detect a floating distance from the platform with respect to the bottom stop and to generate a sign indicating it.
    [035] A programmed control system 40 is provided which includes an automatic platform height control system 40 arranged to raise and lower the feeder housing 14 in response to the fluctuation sensor signal 39 in order to try to maintain the distance from fluctuation in a determined amount required. The determined value is selected so that the platform is free to float between bottom stop 38 and an upper limit of movement up and down to a certain point in order to accommodate changes in height from the ground. Thus, the distance from the platform to the ground is controlled by the gauge wheels and the weight of the platform is primarily supported in the suspension of the feeder housing. In the event that the determined float distance of the bottom stop 38 decreases because the platform has moved downwards with respect to the feeder housing 14, the lift cylinders 15 are operated by the control system 40 using the automatic height control input 39 to lower the feeder housing. In the event that the determined float distance from the bottom stop increases as detected by sensor 39 because the platform has been moved upwards with respect to the feeder housing, the lift cylinders 15 are operated by control 40 to lift the feeder housing.
    [036] In operation, the platform is launched on the ground until the gauge wheels contact the ground, and makes the platform “float” with respect to the adapter frame. Programmed control 40 is adjusted so that the combine feeder housing 14 stops lowering when the preset amount of the platform for adapter separation (float) is obtained as detected by sensor 39. This allows the platform to move to up and down smoothly to follow the contour of the soil. To change the cutting height, the cylinders attached to the gauge wheels are operated. The programmed control 40 then makes the main lift cylinders 15 reacted so that the preset float is maintained.
    [037] The platform assembly 20 is thus mounted in the feed housing 14 of the combine 12 for movement in a forward working direction D through a field carrying a permanent crop to be harvested.
    [038] Platform assembly 20 includes platform 21 with platform frame 21A supporting mower cutter bar 23 through a front of the platform frame to cut the permanent crop and a reel 21R on 21X pivoting support arms for load the crop on the cutter bar. The rubber pads 24, 25 form a harvest transport device for transporting the harvest inwards from the ends of the platform to the collection location 26 to feed the harvester.
    [039] Adapter 22 forms a mounting arrangement for mounting the platform frame to the combine feeder housing 14. The first and second ground engagement gauge wheels 27, 27A on the platform frame one on each side of the feeder housing are mounted on the platform frame 21A in a position spaced behind the cutter bar 23.
    [040] Cylinders 29 provide first and second adjustable connections for adjusting the height of the first and second 27, 27A gauge wheels respectively with respect to the platform frame in response to a height entry from the control system 40.
    [041] Cylinder 32 acts in response to an angle input from the control system 40 as an angle adjustment element for tilting the platform frame 21a to and fro around the axis 22X at the front end of the support arms. 22C of the suspension 22 where the axle 22X is transversal to the front working direction D with respect to the mounting arrangement.
    [042] As shown in Figure 1, platform 21 comprises a three-part platform with a central section 211 and two wing sections 212, 213 where each of the wing sections is fixedly coupled to the center section on a coupling 214. this arrangement is well known and shown in many claimants' patents here.
    [043] Control system 40 is operable by an operator / driver of the combine through a driver interface 41 in the cab that is arranged for the driver to enter a first entry 45 by a control button 45a acting to adjust a value of a required height of the cutter bar from the ground and a second entry 46 by a control knob 46A acting to adjust a required angle value of the platform with respect to the ground. The driver interface is shown in more detail in Figure 4 and includes a screen 41 that can be a touch screen, and a plurality of selection buttons 42 and a dial 43.
    [044] An icon 44 on screen 41 shows the driver the input parameters above the required height of the cutter bar from the ground as indicated in 45 and the platform angle as indicated in 46. The driver can select a value to be entered at a predetermined time or can enter a series of predetermined values to be selected when required.
    [045] It will be appreciated that the height of the cutter bar and the angle of the platform are not directly proportional to the adjustment of ground wheels 27, 27A by the cylinders 29 and the adjustment of the cylinder 32. That is, the adjustment of the cylinder 32 to adjust the platform angle also adjusts the height of the ground of the cutter bar and also the adjustment of the cylinders 9 to adjust the height of the cutter bar also changes the platform angle. Thus, the control system 40 that connects to the driver interface 41 includes a program responsive to the first and second inputs 45, 46 to generate height input on the first and second adjustable connections 29 and the angle input for the adjustment cylinder. angle 32 to automatically obtain the determined value 45 of a required height of the cutter bar from the ground and the determined value 46 of the required angle of the platform in relation to the ground.
    [046] This acquisition of the height entry and the required angle entry can be obtained from a lookup table 48 that contains all the calculated data corresponding to determined values of platform angles and platform height. As an alternative, calculations can be performed in real time with a predetermined algorithm or formula. The lookup table 48 provides the required sensor position of the actuators 32 and 29 for the matrix of desired heights and table angles given.
    [047] The arrangement for controlling the height of the platform in relation to the combine by adjusting the position of the feeder housing 14 is also arranged so that it automatically retains the required platform height using the input signal from sensor 39 in order to maintain the central part of the platform in the feeder housing 14 at the height required to match the height on the gauge wheels. This can be done by providing a direct signal from the sensor 39 to the feeder housing control cylinders or by the floating height control system described above operated by the control 40.
    [048] The combine includes a control system operable by the 401 driver (Figure 1) and the driver interface 41 of the control system 40 is a separate control system in the cab, but independent of the 401 control system for the combine.
    [049] As shown in Figure 4, driver interface 41 still includes a third input 47 introduced using a button 47A that acts to adjust a required speed value of the harvesting device or rubber pads 24, 25. This is merely an example of operating parameters that can be controlled on the same interface 41.
    [050] Thus, in operation, the driver selects one of the buttons 45A, 46A and 47A depending on the parameter to be changed, and uses the dial or scroll wheel to enter the required value.
    [051] Figure 5 shows an interface screen showing the return sensors on the actuators described above including actuators 29 and 32 and float cylinders 22C so that the driver can monitor the actual positions assumed by those components.
    [052] Figure 6 shows an interface screen showing three separate presets for the cutting height and platform angle as described above.
