JOHNSON - Web page: https://patentgrep.com/patent/US20190166759A1 ## CPC - A01D 41/1217: {Unloading mechanisms} - A01D: HARVESTING; MOWING ## Abstract An unloading conveyor of an agricultural harvesting machine is pivotably mounted to a frame for pivoting movement through a movement range that is defined between first and second end positions. Movement of the unloading conveyor within the movement range is controlled by movement of a user-actuated scroll wheel. ## Claims ### Claim 1 An agricultural harvesting machine comprising: an unloading conveyor pivotably mounted to a frame for pivoting movement through a movement range defined between first and second end positions; and a control system configured to produce controlled movement of the unloading conveyor within the movement range in response to a user input signal, wherein the control system comprises a scroll wheel device arranged to generate the user input signal. ### Claim 2 (depends on 1) The harvesting machine of claim 1, wherein the scroll wheel device comprises a user-actuated scroll wheel, and wherein the control system is operable to move the unloading conveyor in a first swing direction in response to user-actuation of the scroll wheel in a first scroll direction, and to move the unloading conveyor in a second swing direction in response to user-actuation of the scroll wheel in a second scroll direction opposite to the first scroll direction. ### Claim 3 (depends on 2) The harvesting machine of claim 2, wherein the control system is operable in a manual mode wherein movement of the unloading conveyor is stopped by the control system in response to user-actuation of the scroll wheel being stopped, and the control system is further operable in an automatic mode wherein movement of the unloading conveyor is continued by the control system after actuation of the scroll wheel is stopped and until detection by the control system that the unloading conveyor has reached a predefined position or that actuation of the scroll wheel has restarted. ### Claim 4 (depends on 3) The harvesting machine of claim 3, wherein the scroll wheel device is arranged to generate a scroll speed signal in response to user-actuation of the scroll wheel, wherein the scroll speed signal has a value that is representative of the scroll speed, and wherein the control system is configured to control the movement of the unloading conveyor dependent upon the scroll speed signal. ### Claim 5 (depends on 4) The harvesting machine of claim 4, wherein the control system is configured to operate in the manual mode when it determines that the scroll speed is below a predetermined first threshold value. ### Claim 6 (depends on 5) The harvesting machine of claim 5, wherein the control system is configured to initiate the automatic mode when it determines that the scroll speed is above the predetermined first threshold value. ### Claim 7 (depends on 5) The harvesting machine of claim 5, wherein the control system is arranged to disregard the scroll speed signal when the scroll speed is below a predetermined second threshold value that is below the first threshold value. ### Claim 8 (depends on 3) The harvesting machine of claim 3, wherein the control system further comprises a press-actuated control switch for switching the control system between manual mode operation and automatic mode operation. ### Claim 9 (depends on 8) The harvesting machine of claim 8, wherein the press-actuated control switch is integrated into the scroll wheel device. ### Claim 10 (depends on 8) The harvesting machine of claim 8, wherein the control system comprises a control handle which includes the scroll wheel device on a front side and the press-actuated control switch on a rear side. ### Claim 11 (depends on 1) The harvesting machine of claim 1, further comprising a conveyor drive system coupled to the unloading conveyor. ### Claim 12 (depends on 11) A combine harvester comprising a harvesting machine according to claim 11. ### Claim 13 (depends on 12) The combine harvester of claim 12, wherein the control system further comprises a press-actuated control switch for activating the conveyor drive system. ### Claim 14 (depends on 13) The combine harvester of claim 13, wherein the press-actuated control switch is integrated into the scroll wheel device. ### Claim 15 (depends on 13) The combine harvester of claim 13, wherein the control system comprises a control handle which includes the scroll wheel device on a front side and the press-actuated control switch on a rear side. ### Claim 16 (depends on 12) The combine harvester of claim 12, further comprising a grain tank, a grain delivery conveyor arranged between the grain bin and the unloading conveyor, and a flow control system arranged to selectively move a restrictor member in the grain delivery conveyor, wherein the control system is operable in a flow control mode wherein the flow control system is controlled by the control system in response to user input signals generated by the scroll wheel device. ### Claim 17 (depends on 16) The combine harvester of claim 16, wherein the flow control mode is activated in the control system when the conveyor drive system is activated. ### Claim 18 (depends on 11) The combine harvester of claim 11, further comprising a discharge spout mounted to a discharge end of the unloading conveyor, wherein the discharge spout is movable with respect to the unloading conveyor by a spout control actuator, and wherein the control system is operable in a spout control mode wherein the spout control actuator is controlled by the control system in response to user input signals generated by the scroll wheel device. ### Claim 19 (depends on 18) The combine harvester of claim 18, wherein the spout control mode is activated in the control system when the conveyor drive system is activated. ### Claim 20 (depends on 1) A method of controlling a harvesting machine according to claim 1 and a crop-receiving cart unit during an unload event, wherein the control system is operable in a cart control mode wherein cart positioning commands are generated in dependence upon user input signals generated by the scroll wheel device. ### Claim 21 (depends on 20) The method of claim 20, wherein the control system comprises a press-actuated control switch, wherein when in the cart control mode with the control switch in a non-actuated state longitudinal cart positioning commands are generated in dependence upon user input signals generated by the scroll wheel device, and wherein when in the cart control mode with the control switch in an actuated state, transverse cart positioning commands are generated in dependence upon user input signals generated by the scroll wheel device.
