[Figure 9]1 is a flowchart showing a display control procedure for a combine harvester according to one embodiment of the present invention. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0008] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In Fig. 1 and Fig. 2, C is a combine harvester, and the combine harvester C includes a traveling machine body 1, a reaping section 2 that harvests culms, a threshing section 3 that threshes and selects grains from the harvested culms, a grain tank 4 (tank) that stores the selected grains, an auger 5 that transports the grains in the grain tank 4 to the outside of the machine, a control section 6 on which a driver rides, and a crawler-type traveling section 7.

[0009] 3, the combine harvester C is provided with a control unit 8 that executes various types of control. The control unit 8 includes a vehicle speed sensor 9 (transmission rotation sensor, main shift lever potentiometer, etc.) that detects the vehicle speed of the combine harvester C, a harvesting / threshing clutch sensor 10 that detects the connection / disconnection state of a harvesting / threshing clutch that connects / disconnects the harvesting power and the threshing power, a grain culm sensor 11 that detects the presence or absence of harvested culms on the grain culm transport path, a GNSS 12 (machine position detection means) such as GPS that detects the machine position of the combine harvester C, a yield sensor 13 that detects the amount of grain in the grain tank 4 (an impact sensor that detects the incoming supply amount, a pile height sensor that detects the pile height, etc.), and The combine harvester C is equipped with a number of sensors (e.g., a sensor that measures the load of the harvester, a weight sensor that measures the tank weight, etc.), a full position display switch 14 that displays the predicted machine position when the grain tank 4 will be full, a rice grain sensor 15 that turns ON when the grain pile height in the grain tank 4 reaches a predetermined height, a fuel remaining sensor 16 that detects the remaining amount of fuel in the fuel tank (not shown) of the combine harvester C, a touch panel LCD monitor 17 (display device) located on the control unit 6, and a communication unit 18 that can communicate with a transport vehicle (communication unit of a vehicle that collects harvested grain) and a mobile terminal (terminal carried by an assistant) not shown.

[0010] The control unit 8 also includes a memory unit 19 that stores farm field map information. The farm field map information may be information obtained from an external source via the communication unit 18, or information created based on machine position data when traveling to reap the crop in the farm field.

[0011] The control unit 8 includes a full tank travel distance calculation means, a travel route calculation means, a tank full predicted position calculation means, and a display control means, as functional components realized by cooperation between hardware and software.

[0012] The full travel distance calculation means calculates the travel distance until the grain tank 4 is full. For example, the operation state of the combine harvester C is judged by the vehicle speed sensor 9, the harvesting clutch sensor 10, the grain stalk sensor 11, etc., and when it is judged that harvesting is in progress, the detection data values ​​of the GNSS 12, the yield sensor 13, etc. are read, and a correlation between the harvesting travel distance and the harvest amount is obtained based on the actual measurement values, and the remaining travel distance until the tank is full is calculated from the correlation and the storage status of the grain tank 4. The above correlation is constantly updated based on the accumulated actual measurement data, and the accuracy can be improved as the harvesting operation is performed and the accumulated data increases.

[0013] The travel route calculation means calculates the travel route of the combine harvester C relative to the field. The main mowing travel procedures of the combine harvester C include a circular mowing procedure in which the four sides of the rectangular uncut land area are mowed counterclockwise, and a two-way mowing procedure in which two opposing sides of the rectangular uncut land area are mowed counterclockwise. By registering the mowing procedure to be adopted in advance or determining the mowing procedure according to the mowing travel situation, it becomes possible to calculate (predict) the subsequent travel route based on the mowing procedure and the shape of the uncut land.

[0014] The tank full predicted position calculation means calculates a tank full predicted position of the combine harvester C relative to the farm field. For example, the tank full predicted position is calculated based on the travel distance to the full tank calculated by the full tank travel distance calculation means and the predicted travel route calculated by the travel route calculation means.

[0015] As shown in Figures 4 to 6, the display control means displays a field map on the touch panel LCD monitor 17, and displays on this field map the already-mowed land area K, the untouched land area M, the current vehicle position P1, the predicted driving route R and the predicted tank full position P2.

[0016] More specifically, the display control means first displays a farm field map display screen as shown in Fig. 4. This screen displays the already-mowed land area K, the unmowed land area M, and the current machine position P1. In addition, the above-mentioned full load position display switch 14 is displayed as a touch button at the bottom left of the screen.

[0017] When the full position display switch 14 is touched, the display control means displays a full position display screen as shown in Fig. 5 or Fig. 6. The full position display screen shown in Fig. 5 is a full position display screen in a circular mowing display mode that is applied when the mowing procedure is circular mowing, and this screen displays the area of ​​already mowed land K, the area of ​​unmowed land M, the current machine position P1, the predicted travel route R, the predicted tank full position P2, and the travel distance until the tank is full.

[0018] The full tank position display screen shown in Fig. 6 is a full tank position display screen in a two-directional mowing display mode that is applied when the mowing procedure is two-directional mowing, and this screen also displays the area of ​​already-mowed land K, the area of ​​unmowed land M, the current machine position P1, the predicted travel route R, the predicted tank full position P2, and the travel distance until the tank is full. However, in two-directional mowing, the predicted travel route R includes a mowing travel route and a non-mowing travel route, so that the mowing travel route and the non-mowing travel route can be distinguished from each other, for example, by showing the mowing travel route with a solid line and the non-mowing travel route with a dashed line.

[0019] Furthermore, the display control means may display a predicted fuel exhaustion position P3 and a distance traveled until fuel runs out, as shown in Fig. 7. Fig. 7 shows a full tank position display screen in the circular mowing display mode, which shows a predicted fuel exhaustion position P3 and a distance traveled until fuel runs out, and on this screen are displayed the already-mowed land area K, the unmowed land area M, the current machine position P1, the predicted travel route R, a predicted full tank position P2, a predicted fuel exhaustion position P3, a distance traveled until the tank is full, and a distance traveled until fuel runs out.

[0020] The travel distance until the fuel runs out can be calculated by, for example, determining the travel state of the combine C using the vehicle speed sensor 9, etc., and when it is determined that the combine C is traveling, reading the detection data values ​​of the GNSS 12, the fuel remaining sensor 16, etc., and calculating the correlation between the travel distance and the remaining fuel amount based on the actual measured values, and then calculating the correlation and the remaining fuel amount in the fuel tank. The predicted fuel run-out position P3 can be calculated based on the calculated travel distance until the fuel runs out and the predicted travel route calculated by the travel route calculation means.

[0021] Furthermore, the display control means may be configured to display the machine position, travel route, and predicted tank full position on the touch panel liquid crystal monitor 17 when the amount of harvested crop stored in the grain tank 4 reaches a predetermined amount or more. For example, the full position display screen shown in Fig. 5 or 6 is displayed based on an ON signal from the rice sensor 15, which turns ON when the piled-up height of grains in the grain tank 4 reaches a predetermined height. In this way, the operator's effort in operation can be reduced compared to when the full position display switch 14 is required to be operated.

[0022] Next, a procedure for setting a predictive full state display and a procedure for controlling a display for implementing the above-mentioned functional configuration will be described with reference to FIGS.

[0023] The fullness prediction display setting process shown in Fig. 8 is a process for setting the direction of the culm rows in the field and the reaping method (reaping procedure) in advance, and is executed based on the display and touch operation of the touch panel liquid crystal monitor 17. The control unit 8 first determines whether the row direction has been specified (S11), and if the result of this determination is YES, it prompts the user to select a reaping method (S12). Then, if two-way reaping is selected, the control unit 8 sets the two-way reaping display mode (S13), and if circular reaping is selected, it sets the circular reaping display mode (S14).

[0024] 9 shows the process executed during work. The control unit 8 first reads the machine information (position information, operation information) (S21), and then distinguishes between already-mown land and unmown land based on the field map information and the machine information (S22), and specifies the unmown land area of ​​the field (S23). Next, the control unit 8 reads the full load prediction display setting information (S24), and calculates the predicted travel route and full load prediction position based on the unmown land area information of the field, the full load prediction display setting information, and the machine information (position information, operation information) (S25). After that, the control unit 8 displays the field map information, machine position information, travel route information, full load prediction position information, etc. on the touch panel liquid crystal monitor 17 (S26), and transmits this information to the transport vehicle or a mobile terminal (S27).

[0025] According to the present embodiment configured as described above, the combine harvester C comprises a traveling body 1, a grain tank 4 for storing the harvested product, and a touch panel LCD monitor 17 for displaying information. The combine harvester C is equipped with a GNSS 12 for detecting the current position of the body relative to the field, a full-fill travel distance calculation means for calculating the travel distance until the grain tank 4 is full, a travel route calculation means for calculating the travel route relative to the field, a predicted tank full position calculation means for calculating the predicted tank full position of the traveling body 1 relative to the field, and a display control means for displaying the body position, the travel route and the predicted tank full position on the touch panel LCD monitor 17. This makes it easier to determine the position to interrupt harvesting, the position to transport the harvested product in the grain tank 4 to a transport vehicle, etc., thereby improving work efficiency.

[0026] In addition, when the amount of harvested goods stored in the grain tank 4 reaches or exceeds a predetermined amount, the display control means displays the machine position, travel route, and predicted tank full position on the touch panel LCD monitor 17, thereby reducing the operator's effort compared to when the full position display switch 14 is required to be operated.
