Oite the Konbai down while checking the engine load and the operating speed, in order to be a good working condition of the utmost efficiency, so that the adjustment of the working speed is performed.
The addition of description, the running load and by field of hardness, by nature due to cutting load and threshing load field of culms, since the engine load at the same work rate is to vary, the engine load is excessive load By adjusting to the working speed that travels while cutting with an appropriate load that is not an excessive load, it is possible to obtain an efficient cutting process working state. Will be done. In adjusting the work speed in this way, it is definitely easy to adjust the proper work speed by grasping the correspondence relationship between the engine load and the work speed for the field on which the cutting process work is performed. . That is, a field where the work load tends to be high even though the work speed is low, or a work load where the work load is low and the work load is low, although the work speed is high. If the engine load is lower than the appropriate load and the work speed is increased when the engine load is lower than the proper load, If so, increase the speed slightly to suppress overloading of the engine load, and conversely, if the field tends to have a low work load, increase the speed more quickly. It will definitely be easy to adjust the proper work speed, such as making the work speed appropriate.

  In the above conventional configuration, the engine load can be displayed in an easily understandable state as to what ratio the engine load is within the load changeable range between the minimum load and the maximum load. It is possible to determine how much the engine load is different from an appropriate value for work, for example, the maximum value in the appropriate load range or a value close to the engine load.

  However, in the above-described conventional configuration, the work speed is displayed in a numerical display format, so that it is difficult for the operator to understand the work speed sensuously, and it is troublesome for the worker to read the work speed. It was a thing. In other words, if the display form is a numerical display, it is difficult for the operator to sensuously know how fast the current work speed is within the speed adjustable range from the displayed numerical information. .

  For this reason, in the above-described conventional configuration, it is difficult to sensuously know how much the current working speed is within the speed adjustable range. It is difficult to grasp the correspondence relationship with the work speed.For example, when the work speed is increased when the engine load is lower than the appropriate load despite the fact that the work load tends to be large, a large amount is required. However, it may be difficult to properly adjust the work speed, for example, the engine load becomes excessive.

An object of the present invention is to provide a combine display device that displays an engine load and a working speed in a state in which a correspondence relationship between the engine load and the working speed is easily grasped.

Next, the lighting part adjacent to the maximum load display position side of the lighting part switches from the unlit state to the lighting state. In this way, as the engine load increases, the lighting unit that switches from the unlit state to the lit state sequentially moves toward the maximum load display position. Then, the operator can read the engine load from the position of the lighting unit that switches from the unlit state to the lit state.
When the engine load display section is configured in the lighting display type display form, the change in the position of the lighting section that switches from the unlit state to the lit state will change to the next lighting section after the working speed and engine load fluctuate to some extent. Will move. That is, the display state of the lighting part does not change only by a slight change in the engine load, and the display state does not change frequently with respect to fine fluctuations in the engine load, so that the display is easy to see.

And the control part 28 is comprised so that the said each cylinder and each motor may be driven based on the information of each said sensor, and various controls, such as cutting height control, unloader control, and threshing control, may be performed.

And the said control part 28 becomes a structure which implements the display control which controls the display state in the display unit C. FIG. Hereinafter, specific contents of display control by the control unit 28 will be described.
As shown in FIG. 11, the control unit 28 operates the work speed meter 12 so as to correspond to the current work speed based on the detection information of the vehicle speed sensor S4, and the engine based on the detection information of the engine rotation speed sensor S5. The engine tachometer 14 is operated so as to correspond to the rotational speed of E, and the fuel meter 15 is operated so as to correspond to the fuel remaining amount in the fuel tank based on the detection information of the fuel remaining amount sensor S9 (step 1). .

  When the description of the display of the work speed is added, the control unit 28 causes the turning angle of the indicator needle 12a of the work speed meter 12 to be a turning angle corresponding to the current working speed detected by the vehicle speed sensor S4. The operation of the rotation drive unit of the work speed meter 12 is controlled.

  Similarly, the rotation speed of the indicator needle 14a of the engine rotation speed meter 14 is the rotation angle corresponding to the current engine rotation speed detected by the engine rotation speed sensor S5. The operation of the rotation drive unit of the engine rotation speed meter 14 is controlled. Similarly, with respect to the fuel gauge, the fuel gauge 15 so that the turning angle of the indicator needle 15a of the fuel gauge 15 becomes a turning angle corresponding to the current remaining fuel amount detected by the remaining fuel amount sensor S9. The operation of the rotation drive unit is controlled.

  Further, based on the command information of the sub-shift switch 9 and the sub-shift neutral switch 10, the operation of the sub-shift hydraulic cylinder 65 is controlled so as to change to the corresponding shift state, and the sub-transmission device 42 is operated to shift. However, since it is possible to determine the current shift state of the current sub-transmission device 42 based on the detection information of the sub-transmission sensor S10 at that time, the current state of the sub-transmission display unit C4 is The shift state in which the auxiliary transmission 42 is in the state is displayed (step 2). That is, the illumination lamp 73 is turned on and brightly displayed for any of the high-speed display portion 16, the low-speed display portion 17, and the neutral display portion 18 of the sub-shift display portion C 4, and the illumination lamp 73 is turned off for the others. Let it darken.

  Further, the control unit 28 controls the operation of the cutting shift hydraulic cylinder 66 so as to be in a corresponding shift state based on the command information of the cutting shift changeover switch 11 and shifts the cutting transmission 43. Based on the detection information of the cutting shift sensor S11, it is possible to determine which shift state the current cutting transmission 43 is in. Therefore, on the cutting shift display C5, the current cutting transmission is displayed based on the determination result. Which shift state 43 is displayed is displayed (step 2). Specifically, the illumination lamp 73 corresponding to one of the high-speed display portion 19 and the low-speed display portion 20 of the cutting shift display portion C5 is turned on, and the other illumination lamps 73 are turned off.

  Then, in a normal state where the combine is operating normally, the control unit 28 displays the plurality of segment display units 13a in the engine load indicator 13 from one end side in the arrangement direction, for example, as shown in FIG. The engine load is displayed by sequentially increasing the number of segment display sections 13a to be displayed, and in an abnormal state in which an abnormality has occurred in the combine, all of the plurality of segment display sections 13a are blinked and displayed (step 3, 4).

  The structure for detecting the engine load will be described. In this combine, when the engine E is in a no-load state where no load is applied, the operator performs an accelerator operation so that the engine speed is set in advance. The accelerator operation position of the engine E is adjusted so as to become the set reference rotation speed. When the engine rotation speed becomes the reference rotation speed, the position is fixed at the accelerator operation position and the subsequent work is performed. ing.

  When a load is applied to the engine E, the engine rotation speed decreases from the reference rotation speed in accordance with the magnitude of the engine load. It is set as map data in a state where the magnitude of the engine load is associated. Therefore, the control unit 28 calculates the difference between the engine rotation speed detected by the engine rotation speed sensor S5 and the reference rotation speed, that is, the engine rotation speed decrease amount, and calculates the engine rotation speed decrease amount and the The engine load is determined based on the map data.

  When displaying the engine load thus obtained, the control unit 28 displays the 13 segment display units 13a from the first one located at one end in the arrangement direction, that is, the counterclockwise end. The engine load is displayed in such a manner that the number of segment display portions 13a to be lit up is sequentially increased. Accordingly, when the engine load is an appropriate load, the green segment display portion 13a is lit, and when the engine load increases and exceeds the set value to become a caution load state, in addition to the eight green segment display portions 13a. The yellow segment display portion 13a lights up. Furthermore, when the engine load increases and exceeds the upper limit value, the red segment display unit 13a is turned on in addition to the eight green segment display units 13a and the three yellow segment display units 13a. Become.

  Further, in a normal state where the combine is operating normally, the control unit 28 performs display processing for displaying various types of notification information as described above on the auxiliary display unit C3 (step 5).

In this display process, every time the mode changeover switch 80 is pressed, the plural information display state and the minority information display state are alternately switched.
Specifically, in the multiple information display state, as shown in FIG. 10 (a), as the multiple types of notification information, the grain stored in the Glen tank 3 (in the figure, expressed as “fir”). ), The amount of the sorting processed product on the swing sorting plate 54 detected by the sheave sensor S8 (denoted as “sheave” in the figure), and the cooling water in the engine E detected by the water temperature sensor S7. Each water temperature information is displayed. In addition to the information, the left and right turn signal displays 74, the hour meter 75 indicating the combined operation time of the combine, the charge alarm display 76 indicating that the battery charge is low, and the oil alarm display 77 indicating the oil abnormality Are also displayed side by side. Further, in the state of switching to the minority information display state, every time the display changeover switch 81 is pushed, the selected processed product amount, the grain storage amount, and the temperature of the cooling water, as shown in FIG. In a state where any of the information is enlarged and displayed, the display contents are sequentially switched in a preset order.

  The minority information display state is not limited to a configuration in which any one of the plurality of pieces of notification information is displayed in an enlarged state, but as shown in FIG. The plurality of notifications, such as a state in which the water temperature) and the amount of grain storage (fir) are displayed side by side, a state in which the amount of processed material (sieve) on the swing sorting plate 54 and the amount of grain storage (fir) are displayed side by side, etc. It is good also as a structure which switches in the order set beforehand, every time the display switch 81 is operated in the state which displays two alerting | reporting information of information.

  Then, in an abnormal state where the combine is abnormal, the control unit 28 causes all of the 13 segment display units 13a in the engine load indicator 13 to blink (step 6). The abnormal state here is a case where an abnormality that makes it difficult to continue the cutting operation has occurred in any part of the combine. For example, an exhaust wall clogging detection switch There is an abnormal discharge clogging or the like in which the exhaust straw is clogged in the exhaust straw cutter unit 64 when S15 is turned on. In addition to this waste straw clogging, there are abnormalities such as clogging of harvested cereal grains in the cutting unit 1 and abnormal overheating of the engine.

  Moreover, the control part 28 respond | corresponds to the said abnormality instead of several types of alerting | reporting information, such as above-mentioned stored grain amount, the amount of sorting processed materials, and water temperature, in the abnormal state where the abnormality has generate | occur | produced in the combine. Message information is displayed on the auxiliary display C3 (step 7). When an abnormality occurs in which the above-described waste straw is clogged, as shown in FIG. 10 (b), message information for dealing with the abnormality that occurred at that time, for example, “the waste straw cutter is clogged with straw Message information like "Please remove the wall" is displayed.
