Accordingly, when the Glen tank 20 is positioned at the closing position, the Glen tank 20 is supported by the tilting (swinging) freely in the front-rear direction by the width t of freedom with the fulcrum projecting piece 31 as the fulcrum as described above. The front lower end portion 20d of the Glen tank 20 abuts on the weight sensor 33, and the weight of the front side of the Glen tank 20 acts on the weight sensor 33, and the weight sensor 33 detects the front side of the Glen tank 20 by the weight sensor 33. The weight can be measured.
[0042]
As a result, the weight of the grains stored in the Glen tank 20 can be accurately estimated by the weight sensor 33, and the yield in the field can be locally and reliably grasped, and the entire field can be grasped. Can accurately recognize the harvest situation.
[0043]

Thus, the pitch angle of the vehicle body is detected by the pitch angle sensor 40, the roll angle of the vehicle body is detected by the roll angle sensor 41, and the measured weight detected by the weight sensor 33 is corrected based on the detection results. Thus, the weight of the grains in the Glen tank 20 can be estimated more accurately.
[0046]
Moreover, the weight of the grain is corrected to the weight of the grain at a specified moisture value (for example, 15%) based on the moisture value of the grain detected by the moisture sensor 25, and the corrected weight is harvested (yield). The harvested weight (yield), which is the weight of the grain, the water content, and the corrected weight, is displayed on the display panel unit 46 as shown in FIG. 47 is a weight display switch, 48 is a moisture display switch, 49 is a yield display switch, 50 is a calculation switch, and 51 is a result display section.

Based on the moisture values of the grains for each of the sections a1, a2,... Detected by the sensor 25, the weights of the grains at the specified moisture value are corrected, and the corrected weights are displayed as maps on the display panel unit 46 as the yield. (See FIG. 10).
[0048]
That is, as shown in FIG. 9, the section of the field B performs the moving process of the vehicle body during the harvesting operation, for example, the harvesting operation is performed while the vehicle body is moved forward from an end position on the left side of the field B, and the left side of the field B It is made to rotate at the end position on the other side (A), performs cutting while advancing the vehicle body from the end position on the right side of the field B, and turns at the end position between the right and left sides of the field B. (B) The mowing operation is performed while the vehicle body is advanced from the end position on the left side of the field B, and it is rotated at the end position on the left side of the field B (C). The mowing operation is performed while the vehicle body is advanced from the part position, and the hull operation is performed at the end position between the right and left sides of the field B (d), and the mowing operation is performed while the vehicle body is advanced from the end position on the left front side of the field B. Then, it is rotated at the end position on the left side of the field B (e), The mowing work is performed while the vehicle body is advanced from the end position on the right side, and the body is rotated at the end position between the right side of the field B (f), and the vehicle body is advanced from the end position just before the center of the field B. While doing the reaping work.
[0049]
As described above, when performing the mowing operation while moving the vehicle body in a spiral shape, one section is set from the cutting width (vehicle width) W and a predetermined moving distance L (for example, 10 m), and the entire field B is set. Make a matrix.
[0050]
Here, the above-mentioned grain stick sensor 43 detects the presence or absence of a grain stick of a crop, so that it is possible to recognize the start of cutting and the cutting through in the cutting operation process.
[0051]
The vehicle speed sensor 44 detects the number of rotations of the transmission shaft of the transmission to determine the moving speed and the moving distance L of the vehicle body.
[0052]
Furthermore, the time (for example, 15 seconds) from the start of the mowing operation until the kernel is stored in the Glen tank 20 is subtracted from the time when the weight of the kernel stored in the Glen tank 20 is detected. By doing so, the yield at points passed before that time is not counted.
[0053]
As shown in FIG. 10, the display panel unit 46 displays a map M similar to the field B in the form of a matrix, and the map M includes any one of the weight, moisture, and yield (yield) of the grain. Is selectively displayed on a map, and is displayed in different colors according to the density of colors in a stepwise manner in accordance with the magnitude of the local numerical value for each section, so that the operator can easily see this map M by visually recognizing the map M. So that you can understand the situation.
[0054]
That is, when confirming any of the weight, the moisture, and the yield (yield) of the cereal in the field B, the weight display switch 47, the moisture display switch 48, and the yield display switch 49 provided on the display panel 46 are provided. By pressing a required switch, a map M selected by operating a switch from among the grain weight, moisture, and harvest (yield) can be displayed on the display panel section 46. By visually recognizing, desired crop harvest information can be locally and reliably grasped for each of the sections a1, a2,... So that the harvest situation of the entire field B can be accurately recognized. ing.
