A left turn signal 190 indicating a left turn is positioned above the tank monitor 188, and a right turn signal 191 indicating a right turn is positioned to the right of the engine load indicator 182. The left turn signal 190 and the right turn signal 191 are arranged at the upper left and right corners of the display unit 180, respectively.

  Below the threshing monitor 186 and the sorting monitor 187 is an information display unit 192 that displays various information such as time, gear, alarm, etc., and a selection switch represented by an arrow below the information display unit 192 The touch panel unit 193 including the menu switch is located. The information display unit 192 and the touch panel unit 193 are arranged on the lower edge portion of the display unit 180.

  The engine load indicator 182, the threshing monitor 186, and the sorting monitor 187 are concentrated in the central portion of the liquid crystal display panel 181, in other words, in the central portion of the display unit 180, and are in a position where the user can easily see. Moreover, it is displayed on the same liquid crystal display panel 181, and the user simply looks at the display unit 180 to load information on the engine 40, information indicating the threshing processing status of the grain, and information indicating the processing status of the grain. It is possible to instantly grasp the field of view and quickly grasp the work status.

  Next, selection of crops will be described. FIG. 7 is a schematic diagram showing an example of a crop selection screen. By operating the touch panel unit 193 or the switch 200, the display on the liquid crystal display panel 181 can be changed to a crop selection screen for selecting a crop.

  For example, as shown in FIG. 7, the liquid crystal display panel 181 displays rice, wheat and barley, and the user can select a crop to be cut by operating the touch panel unit 193 or the switch 200.

  Next, the relationship between the selected crop and the threshold for color-coding the engine load indicator 182, the harvest monitor 185, and the threshing monitor 186 will be described. The combine includes a control unit (not shown), and the control unit includes a central processing unit (CPU), a random access memory (RAM), a rewritable storage unit, and the like.

  The storage unit stores an LUT (Look Up Table) indicating the correspondence between the selected crop and the thresholds for color-coding the engine load indicator 182, the harvest monitor 185, and the threshing monitor 186.

  FIG. 8 is a conceptual diagram showing an example of an LUT showing the correspondence between the selected crop and the threshold values for color-coding the engine load indicator 182, the harvest monitor 185, and the threshing monitor 186. As shown in FIG. 8, the engine load threshold value, the threshing monitor threshold value, and the selection monitor threshold value fields each include a first threshold value field and a second threshold value field. The first threshold value is a value indicating the boundary between the blue lighting units 182c, 186a, 187a and the yellow lighting units 182d, 186b, 187b, and the second threshold value is the yellow lighting units 182d, 186b, 187b and the red lighting unit 182e, It is a value indicating the boundary between 186c and 187c.

  For example, a case where rice is selected will be described. When the detection value of the engine load detection sensor 40a is less than A1, only the blue lighting part 182c of the engine load indicator 182 lights up. When the detected value of the engine load detection sensor 40a is greater than or equal to A1 and less than A2, the engine load indicator 182 is lit by the yellow lighting portion 182d in addition to the blue lighting portion 182c.

  When the detection value of the engine load detection sensor 40a is A2 or more, the red lighting part 182e is turned on in addition to the blue lighting part 182c and the yellow lighting part 182d.

  When the detection value of the discharge amount sensor 34a is less than A3, the threshing monitor 186 lights only the blue lighting part 186a. When the detection value of the discharge amount sensor 34a is not less than A3 and less than A4, in the threshing monitor 186, the yellow lighting part 186b is lit in addition to the blue lighting part 186a.

  When the detected value of the discharge amount sensor 34a is A4 or more, the threshing monitor 186 lights up the red lighting unit 186c in addition to the blue lighting unit 186a and the yellow lighting unit 186b.

  When the detection value of the discharge amount sensor 34b is less than A5, only the blue lighting part 187a lights up in the sorting monitor 187. When the detection value of the discharge amount sensor 34b is not less than A5 and less than A6, in the sorting monitor 187, the yellow lighting section 187b is lit in addition to the blue lighting section 187a.

  When the detection value of the discharge amount sensor 34b is A6 or more, in the sorting monitor 187, in addition to the blue lighting unit 187a and the yellow lighting unit 187b, the red lighting unit 187c is lit. When wheat or barley is selected, it is lit in the same manner (A1 to A6 may be read as B1 to B6 or C1 to C6).

  A1 to A6, B1 to B6, and C1 to C6 are values determined by the crop, and are not the same value. Therefore, for example, when the detection value of the discharge amount sensor 34b is X (however, A5 <X <A6, X <B5, C6 <X), if the rice is selected, the sorting monitor 187 has the blue lighting portion 187a and If the yellow lighting part 187b is lit and only wheat is selected, only the blue lighting part 187a is lit. If barley is selected, the blue lighting part 187a, the yellow lighting part 187b and the red lighting part 187c are lit.

  The same applies to the lighting states of the lighting units 182c to 182e and 186a to 186c with respect to the detection values of the engine load detection sensor 40a and the emission amount sensor 34a.

  The evaluation of the detection results of the engine load detection sensor 40a and the emission amount sensors 34a and 34b is often different for each crop. The threshold values corresponding to the color coding of the engine load indicator 182, the threshing monitor 186, and the selection monitor 187 are set according to the crop. Therefore, different evaluations can be reflected in the color coding of the engine load indicator 182, the threshing monitor 186, and the sorting monitor 187.

  Note that it may be configured such that a variety of crops can be selected. For example, after selecting rice on the crop selection screen, the display on the liquid crystal display panel 181 may be changed to a variety selection screen for selecting the type of crop.

  FIG. 9 is a schematic diagram showing an example of a product type selection screen. For example, as shown in FIG. 9, the liquid crystal display panel 181 displays rice varieties Koshihikari, Sasanishiki, and Kinuhikari, and the user operates the touch panel unit 193 or the switch 200 to select the crop varieties to be harvested. You can choose.

  Next, the relationship between the selected variety and the threshold values for color-coding the engine load indicator 182, the harvest monitor 185, and the threshing monitor 186 will be described. The storage unit stores an LUT indicating a correspondence relationship between the selected product type and the threshold values for color-coding the engine load indicator 182, the harvest monitor 185, and the threshing monitor 186.

  FIG. 10 is a conceptual diagram showing an example of an LUT showing the correspondence between the selected variety and the threshold values for color-coding the engine load indicator 182, the harvest monitor 185, and the threshing monitor 186. For example, a case where Koshihikari is selected will be described. When the detection value of the engine load detection sensor 40a is less than a1, only the blue lighting part 182c of the engine load indicator 182 lights up. When the detection value of the engine load detection sensor 40a is greater than or equal to a1 and less than a2, the engine load indicator 182 is lit by the yellow lighting portion 182d in addition to the blue lighting portion 182c.

  When the detection value of the engine load detection sensor 40a is greater than or equal to a2, the red lighting part 182e lights up in addition to the blue lighting part 182c and the yellow lighting part 182d.

  When the detection value of the discharge amount sensor 34a is less than a3, the threshing monitor 186 lights up only the blue lighting part 186a. When the detection value of the discharge amount sensor 34a is not less than a3 and less than a4, in the threshing monitor 186, the yellow lighting part 186b is lit in addition to the blue lighting part 186a.

  When the detection value of the discharge amount sensor 34a is equal to or greater than a4, the threshing monitor 186 turns on the red lighting unit 186c in addition to the blue lighting unit 186a and the yellow lighting unit 186b.

  When the detection value of the discharge amount sensor 34b is less than a5, only the blue lighting part 187a lights up in the sorting monitor 187. When the detection value of the discharge amount sensor 34b is greater than or equal to a5 and less than a6, in the sorting monitor 187, in addition to the blue lighting part 187a, the yellow lighting part 187b is lit.

  When the detection value of the discharge amount sensor 34b is a6 or more, in the sorting monitor 187, in addition to the blue lighting unit 187a and the yellow lighting unit 187b, the red lighting unit 187c is lit. When Sasanishiki or Kinuhikari is selected, the light is similarly turned on (replace a1 to a6 with b1 to b6 or c1 to c6).

  a1 to a6, b1 to b6, and c1 to c6 are values determined by the product type, and are not the same value. Therefore, for example, when the detection value of the discharge amount sensor 34b is X (provided that a5 <X <a6, X <b5, c6 <X), the sorting monitor 187 selects the blue lighting unit 187a and Koshihikari. If the yellow lighting part 187b is lit, if only Sasanishiki is selected, only the blue lighting part 187a is lit. If Kinukari is selected, the blue lighting part 187a, the yellow lighting part 187b and the red lighting part 187c are lit.

  The same applies to the lighting states of the lighting units 182c to 182e and 186a to 186c with respect to the detection values of the engine load detection sensor 40a and the emission amount sensor 34a.

  The evaluation of the detection results of the engine load detection sensor 40a and the discharge amount sensors 34a and 34b is often different for each type, and the threshold values corresponding to the color coding of the engine load indicator 182, the threshing monitor 186 and the selection monitor 187 are set according to the type. Therefore, different evaluations can be reflected in the color coding of the engine load indicator 182, the threshing monitor 186, and the sorting monitor 187.

  Further, the display of the moisture amount monitor 189 may be displayed in a different manner for each crop or variety. For example, the moisture amount threshold value is previously stored in the storage unit, and the background color of the moisture amount monitor 189 is configured to be blue or red.

  When the measured value of the water content measuring device 4d is less than the water content threshold value, the water content is displayed with the background color of the water content monitor 189 set to blue, and the measured value of the water content measuring device 4d is greater than or equal to the water content threshold value. The water content is displayed with the background color of the water content monitor 189 set to red.

  FIG. 11 is a conceptual diagram showing an example of an LUT showing the correspondence between the selected variety and the water content threshold value. The LUT is stored in advance in the storage unit. As shown in FIG. 11, water content thresholds A, B, and C are set for each variety of Koshihikari, Sasanishiki, and Kinuhikari.

  FIG. 12 is a schematic diagram showing the relationship between the measured value of the moisture measuring device 4d and the display mode of the moisture monitor 189. FIG. 12A shows a water content monitor 189 displaying the water content with a red background color, and FIG. 12B shows a water content monitor 189 displaying the water content with a blue background color.

  For example, when the measured value of the water content measuring device 4d is X (however, A <X <B <C), if Koshihikari is selected, the water content monitor 189 displays the water content with the background color set to red. If Sasanishiki or Kinuhikari is selected, the water content monitor 189 displays the water content with the background color blue.

  The LUT indicating the correspondence between the crop and the water content threshold value is stored in the storage unit in advance, and the water content monitor 189 displays the measured value of the water content measuring device 4d as blue or red as the background color according to the selected crop. May be. The change of the background color is an example of a means for indicating that the threshold value has been exceeded, and other means may be used. For example, the color of a number indicating the amount of moisture may be changed, or the number or background may blink.

  In addition, you may comprise so that each threshold value of LUT shown in FIG.8, FIG.9 and FIG.11 can be correct | amended manually. For example, the user operates the touch panel unit 193 or the switch 200 to call up the LUT shown in FIGS. 8, 9, and 11, and each threshold value A1 to A6, B1 to B6, C1 to C6, a1 to a6, b1 to b6. , C1 to c6, A, B, and C are increased or decreased.

  The corrected threshold value is stored in the storage unit. In this case, the storage unit can store the initial value of each threshold separately and return the corrected threshold to the initial value as necessary.

  In addition, a configuration in which the product type selection screen is directly called and displayed on the liquid crystal display panel 181 by operating the touch panel unit 193 or the switch 200 without passing through the crop selection screen may be employed. In addition, when there is a single crop to be harvested, a configuration in which a variety selection screen is displayed instead of a configuration in which a crop selection screen is displayed may be selected.

  In the combine according to the present invention, the evaluation of the moisture content of the grain often differs depending on the crop or the variety of the crop. This can be reflected in the display mode of the quantity monitor 189.

  In addition, each threshold value A1 to A6, B1 to B6, C1 to C6, a1 to a6, b1 to b6, c1 to c6, A, B, and C is manually corrected, and an appropriate threshold value and a moisture amount threshold value are determined by the user's judgment. Can be set. The present invention can also be applied to a bucket-type combine.

  It should be thought that embodiment disclosed this time is an illustration and restrictive at no points. The scope of the present invention is intended to include all modifications within the scope of the claims and the scope equivalent to the scope of the claims.
