  Various information displayed on the screen unit 34 includes traveling speed, parking brake state, straw processing state (cutter, dropper), auxiliary transmission state, cutting height, type of threshing object (rice, wheat, Barley), saw barrel load level, sheave load level, taste, yield, unloader turning, engine speed, water temperature, urea SCR remaining amount, fuel level, operation time, date and other information, operation unit 33 The display control device 40 can acquire information held by the airframe control device 20 by performing communication between the display communication unit 42 and the airframe communication unit 22 as necessary. It is configured to be able to.

  As shown in FIGS. 2 and 3, the casing 31 has a horizontally-long rectangular shape as a whole by, for example, resin injection molding, and each corner has a rounded shape. The surface is formed in a shape that rises while inclining to the near side with respect to the surface of the display unit 32. With such a shape, since the operation unit 33 side can be brought closer to the worker, the operator's finger can easily reach and the operability is good.

  The casing 31 is configured so that the thickness thereof can be grasped by the operator's hand at least on the operation unit 33 side, and the operation unit 33 is configured to be operable when the operator grasps the operation unit 33. ing. The operator can support the housing 31 by turning a finger other than the thumb on the back surface of the housing 31 when operating the operation unit 33 with the thumb. Therefore, a reliable operation is possible even in a situation where the fuselage shakes as the combine 1 travels.

  The housing 31 is configured in a shape in which a lower corner portion on the operation unit 33 side is cut off in a front view. Therefore, when the worker gets on and off or sits down, the leg of the worker, particularly the knee, is difficult to hit. Therefore, it is difficult to get in the way when the worker gets on and off, and both feet can be opened and a stable posture can be taken when sitting. Further, when the operator grasps the operation unit 33, the finger can easily reach an operation tool 38, which will be described later, provided in the operation unit 33, so that the operability is good.

  The engine load state as the work load level of the combine 1 is highly important information from the viewpoint of appropriate work continuation, and such high importance information is displayed separately from the screen unit 34. Visibility is enhanced by displaying separately from various other information by the load display unit 35 provided closer to the worker than the unit 32. Further, the operability is improved by arranging the operation unit 33 near the worker.

  If an image representing the workload level is to be displayed in the same display area of the screen unit 34, a program for representing the workload level is required, and the space for displaying other information images is reduced. Therefore, in order to improve visibility, the screen unit 34 having a larger display area is required. A color liquid crystal monitor requires a larger casing and becomes expensive as the display area increases. By separating the screen unit 34 and the load display unit 35, a program for representing the workload level and the screen unit 34 having a large display area become unnecessary.

  Further, by dividing the screen unit 34 and the load display unit 35, the level of the work load by the load display unit 35 can be reliably expressed even when the screen unit 34 does not function normally for some reason.

  The load display unit 35 includes a plurality of light emitting units arranged in the vertical direction in an elongated opening 31b arranged along the right side of the screen unit 34, for example, a housing 31 as shown in FIG.

  Although the panel body 31d has light transmissivity at the locations where the segments 35a to 35e are disposed, the location corresponding to the segments 35a to 35c is green, the location corresponding to the segment 35d is orange, and the segment 35e The portion corresponding to is colored red.

  Each LED element is controlled to emit light from the segment 35a to the segment 35e in accordance with the level of the work load. For example, when the work load level is low, only the segment 35a is lit, and the segment lit as the work load level increases. When the workload level is the highest, all the segments 35a to 35e are lit.

  The load display unit 35 is configured such that the segments 35a to 35e are arranged in the vertical direction along one side on the right side of the screen unit 34, and the uppermost segment 35e is turned on when the workload level is the highest. It is configured. Therefore, the higher the work load, the easier it is to draw the operator's attention.

  The rectangular opening 31a and the elongated opening 31b are configured to have the same length in the vertical direction, and the load display unit 35 includes the segments 35a to 35e extending over substantially the same length as the vertical direction of the elongated opening 31b. Has been. Therefore, the load display unit 35 is longer than one side on the right side of the screen unit 34 and has a length in the vertical direction of the rectangular opening 31a, that is, a region where the screen unit 34 and a marker arrangement unit 37 described later are disposed. It has the same length as the length.

  By providing the load display unit 35 separately from the screen unit 34, the visibility of the load display unit 35 can be improved. At this time, the load display unit 35 is disposed between the screen unit 34 and the operation unit 33, but the screen unit 34 and the operation unit 33 are not separated from each other, so that the housing 31 can be made compact. .

  Further, the display unit 32 is provided with a marker arrangement unit 37 below the screen unit 34 and spaced from the screen unit 34. The marker arrangement part 37 has the same width as the one side below the screen part 34, and is provided along the one side. Signs 37 a to 37 j corresponding to predetermined information relating to the combine 1 are arranged in the sign arrangement part 37.

  Specifically, the sign arrangement unit 37 includes a sign 37a that blinks in synchronization with blinking of the blinker lamp 18, a sign 37b that lights when an abnormality occurs in the charging system, and a lubrication system during engine rotation. The indicator 37c that lights when the engine is abnormal, the indicator 37d that lights when the engine is abnormal, the indicator 37e that lights when the parking brake is applied, and the indicator 37e that lights when the remaining amount of fuel is low The indicator 37f, the indicator 37g that is turned on when there is an abnormality in the quality of urea water, the indicator 37h that is turned on when an abnormality occurs in the urea SCR system, the indicator 37i that is turned on in synchronization with the lighting of the work light, and the blinker lamp 19 The indicator 37j which blinks in synchronization with the blinking of is provided.

  In the panel body 31d, the portions corresponding to the markers 37a and 37j are green in the locations where the markers 37a to 37j are arranged, while the portions corresponding to the markers 37a and 37j are green, and the markers 37b, 37c, 37d, 37e, and 37h. Corresponding locations are colored red, locations corresponding to the sign 37f are colored yellow, and locations corresponding to the sign 37i are colored blue.

  As shown in FIG. 3, a plurality of white LED elements 37 z are mounted on the substrate 36 as light emitting portions at positions corresponding to the respective signs 37 a to 37 j. Each of the LED elements 37a to 37j is configured to be lit or blinked by controlling the light emission of each LED element in response to the occurrence of an event corresponding to each of the signs 37a to 37j.

  In this manner, the housing 31 can be made compact while providing the marker arrangement portion 37 separately from the screen portion 34. The design of the display unit 32 is enhanced by arranging the screen unit 34, the load display unit 35, and the marker arrangement unit 37 in a rectangular shape as a whole.

(Operation section)
The operation unit 33 is for the operator to perform an operation related to the information image displayed on the screen unit 34 on the right side of the display unit 32, and includes an operation tool 38 that receives the operation of the operator. The operation tool 38 is disposed on the upper end side from the center in the vertical direction in the front view of the housing 31. Since the operation tool 38 is arranged at a position close to the worker and the finger can easily reach, the operability is good.

  The operation tool 38 is a group of operation switches 38a to 38d that enables at least scrolling of the information image displayed on the screen unit 34. Specifically, the upper switch 38a, the left switch 38b, the lower switch 38c, the right switch 38d, the screen A confirmation switch 38e for confirming the content displayed on the unit 34, an information display mode 70 for displaying an information image corresponding to various types of information on the screen unit 34, and a setting mode for displaying a setting screen related to display on the screen unit 34 A setting switch 38f for switching between 80 (see FIG. 8) is provided.

  The setting switch 38f is arranged on the display unit 32 side, more specifically, on the lower left side of the left switch 38b and the lower switch 38c with respect to the operation switch groups 38a to 38d. The setting switch 38f is operated less frequently than the operation switch groups 38a to 38d. Therefore, by disposing the setting switch 38f at a position farther than the operation switch groups 38a to 38d, the possibility of erroneous operation of the setting switch 38f is reduced.

  The operation tool 38 is disposed inside the trapezoidal opening 31 c, and the operation surfaces of the operation switch groups 38 a to 38 d and the operation surface of the setting switch 38 f are disposed at positions recessed from the surface of the housing 31. .

  The minor warning information image 62 includes a title “fir” representing the notification information and specific contents thereof. In addition, the specific content includes illustrations related to the notification information and comments about the event that caused the notification information to be reported: “The fir is full. Stop the work and discharge the fir.” It is. Note that the minor warning information image 62 according to such an aspect is also referred to as a detailed image.

  When at least an event to be notified about the machine of the combine 1 or the work by the combine 1 has occurred, a detailed image showing the details to be notified is displayed in the main area 50, so that the worker can easily understand the contents. Can be confirmed.

  When the operator manually operates the operation unit 33, for example, when the lower switch 38c of the operation tool 38 is operated, the screen control unit 41 may hide the light warning information image 62 displayed on the screen unit 34. It is configured to be able to. The screen control unit 41 is configured to display a simple image that simply represents the content to be notified in the sub-region 51 in accordance with the operation. For example, when “fir” information is present as notification information, if the lower switch 38c of the operation tool 38 is operated, a detailed image corresponding to the “fir” information displayed in the main area 50 is hidden. The title “Fir” in the detailed image is displayed in the sub area 51 as a simple image. At this time, an information image is displayed in the main area 50.

  After confirming the details of the detailed image, the worker terminates the display and displays an information image in the main area 50 according to at least various information related to the setting or state of the machine of the combine 1 or the operation by the combine 1. Display again. In addition, since the simple image which displayed the content of the event which should be alert | reported simply is displayed on the sub area | region 51, the content of the event which should be alert | reported can be confirmed, continuing a driving | operation or a work.

  Further, the screen control unit 41 operates the lower switch 38c of the operation tool 38 again, for example, based on an artificial display switching instruction while displaying the word “fir” as a simple image in the sub area 51. By doing so, the detailed image of the light warning information image 62 instead of the information image displayed in the main area 50, that is, the title “Fir” representing the light warning information image 62 and its specific contents are displayed again. . At this time, since the word “Momi” displayed in the sub-region 51 is not displayed, the display does not become redundant.

  As described above, the screen control unit 41 displays the detailed information in the main area 50 or displays the simple information in the sub area 51 according to the operation of the operation tool 38 when there is mild alarm information. Or display in a manner.

  Furthermore, the screen control unit 41 operates in displaying a plurality of detailed images corresponding to each of the plurality of pieces of notification information in the main area 50, particularly when there are a plurality of pieces of notification information classified as mild warning information. Based on an artificial display switching instruction of the tool 38, a plurality of detailed images are sequentially switched and displayed.

  For example, as shown in FIG. 13, when “fir” information and “sheave” information exist as notification information, a minor warning information image corresponding to “fir” information is displayed in the main area 50 of the screen unit 34. 62 is displayed. Here, when the left switch 38b or the right switch 38d of the operation tool 38 is operated, the minor alarm information image 63 corresponding to the “sheave” information is switched and displayed. Note that priority is set for the notification information, and the notification information is displayed in ascending or descending order according to the priority.

  Further, the screen control unit 41 displays the displayed minor alarm information images 62 and 63 in the main area 50 every time the operator manually operates the operation unit 33, for example, the lower switch 38c of the operation tool 38 is operated. The display is switched to the display as a simple image in the sub area 51.

  Similarly to the above, as shown in FIG. 13, when “fir” information and “sheave” information exist as notification information, the screen unit 34 displays a mild alarm information image 62 corresponding to “fir” information. Is displayed. Here, when the lower switch 38 c of the operation tool 38 is operated, the detailed image corresponding to the “fir” information displayed in the main region 50 is not displayed, and the title “fir” in the detailed image is displayed in the sub region 51. Displayed as a simple image. At this time, a detailed image of the light warning information image 63 corresponding to the “sheave” information is switched and displayed in the main area 50.

  Here, when the lower switch 38c of the operation tool 38 is further operated, the detailed image of the minor warning information image 62 corresponding to the “sheave” information displayed in the main area 50 is not displayed, and the detailed image The title “sieve” is also displayed as a simple image in the sub-region 51. At this time, an information image is displayed in the main area 50.

  When there are a plurality of pieces of broadcast information, for example, when “fir” information and “sheave” information exist as broadcast information, the screen control unit 41 responds to each of the pieces of broadcast information in the sub-region 51.
