  In addition, a grain inlet 27 is formed in the left side wall (inner wall) of the Glen tank 20, and a milling cylinder 28 is interposed between the grain inlet 27 and the above-described sorting unit 7. The refined grains selected in the sorting section 7 through the cereal cylinder 28 are put into the grain inlet 27 → the glen tank 20 and stored.

  Here, a moisture sensor 25 for detecting the moisture of the grain is disposed in the Glen tank 20, and the moisture sensor 25 is on the grain guide body 29 disposed in the lower vicinity of the grain inlet 27. It is made possible to detect the moisture of the grain (fresh grain) that is placed on the grain inlet 27 and flows down on the grain guide 29.

  The lower interlocking connecting portion 21 is provided with the above-described interlocking connecting mechanism in an interlocking connecting portion case 30 formed in a substantially L shape in a side view, and the interlocking connecting portion case 30 has a front end opening 30a. Are integrally connected to the rear wall 20c of the Glen tank 20, and a fulcrum protrusion 31 is protruded downward at the lower end portion, while a ring-shaped fulcrum protrusion receiving body 32 is provided on the body frame 2. The fulcrum protrusion 31 is inserted into the fulcrum protrusion receiving body 32 from above.

  In this way, the Glen tank 20 is pivotally supported by the fulcrum protruding piece 31 protruding from the lower end portion of the interlocking connecting portion case 30 as a fulcrum so as to be pivotable to the left and right around the vertical axis, and the coaxial line is the center. The Glen tank 20 is openable and closable between a closed position where the front end is located on the body frame 2 and an open position where the front end is located outside the body frame 2.

  Therefore, opening the Glen tank 20 to the open position facilitates maintenance of the threshing unit 6, the sorting unit 7, and further a transmission mechanism (not shown) that transmits power from the prime mover unit 14 to each component. It can be carried out.

  In the configuration as described above, the gist of the present invention is that the fulcrum projecting piece 31 as one end of the Glen tank 20 is the vertical swing fulcrum, and between the front lower end of the Glen tank 20 and the vehicle body frame 2. In other words, a weight sensor 33 such as a load cell is arranged.

The 20c is connected to the connecting bolts 35 and 35 with a certain degree of freedom without being completely tightened.

  In this way, the Glen tank 20 can be tilted (oscillated) in the front-rear direction by a width t of freedom with the fulcrum protrusion 31 as a fulcrum.

  A weight sensor 33 is mounted on the vehicle body frame 2 at a position directly below the front lower end 20d of the Glen tank 20 disposed at the closed position. G is the gravity center position of the Glen tank 20 which stored the grain.

  Moreover, as shown in FIGS. 5 and 6, positioning means 36 is provided between the grain tank 20 and the vehicle body frame 2, and is closed between the grain tank 20 and the support frame 6 a provided in the threshing portion 6. Position locking means 37 is provided.

  That is, as shown in FIG. 5 and FIG. 6, the positioning means 36 vertically slides a rod-shaped positioning piece 36b extending vertically through a positioning piece support 36a below the front wall 20e of the Glen tank 20. While being mounted movably, the body frame 2 is provided with a cylindrical positioning piece receiver 36c, and the lower end of the positioning piece 36b is inserted into the positioning piece receiver 36c so as to be freely inserted and removed in the vertical direction for positioning. I have to.

  Further, as shown in FIGS. 5 and 6, the closing position locking means 37 is provided with a fixed hook 37a on the left (inside) upper portion of the front wall 20e of the Glen tank 20, and at the base of the fixed hook 37a. The base of the movable side hook 37b is pivotally supported via a pivot pin 37c provided with an axis in the front-rear direction, and between the movable side hook 37b and the operation lever 37d provided at the lower part of the front wall 20d of the Glen tank 20.

To move the Glen tank 20 to the closed position, and dispose the fixed side hook 37a above the locking pin 37g and return the operation lever 37d to the original position in the same state. The distal end portion is brought close to the distal end portion of the fixed side hook 37a by the elastic biasing force of the tension spring 37h so that the locked state can be achieved by closing both the hooks 37a and 37b around the locking pin 37g.

  Here, the Glen tank 20 can be positioned by the positioning means 36 as described above, and can be locked at the closed position by the closing position locking means 37 as described above. Even when the positioning / closing position is locked, the weight sensor 33 can be tilted (oscillated) in the front-rear direction by the width t of the degree of freedom with the fulcrum protruding piece 31 as a fulcrum so that the weight sensor 33 can sense the weight without any trouble. I have to.

  Therefore, when the Glen tank 20 is positioned at the closed position, as described above, the Glen tank 20 is supported so as to be tiltable (swingable) in the front-rear direction by the width t of the degree of freedom with the fulcrum protrusion 31 as a fulcrum. The front lower end 20d of the Glen tank 20 abuts on the weight sensor 33, and the weight on the front side of the Glen tank 20 acts on the weight sensor 33. The weight sensor 33 causes the front side of the Glen tank 20 to The weight can be measured.

  As a result, the weight of the grain stored in the grain tank 20 can be accurately estimated by the weight sensor 33, and the amount of harvest in the field can be ascertained locally and reliably. Can accurately recognize the harvest situation.

  In the present embodiment, as shown in FIG. 2, a pitch angle sensor 40 as a vehicle body inclination sensor for detecting a vehicle body inclination angle (pitch angle) in the front-rear direction of the vehicle body frame 2 and a horizontal inclination is provided. A roll angle sensor 41 as a vehicle body inclination sensor for detecting an angle (roll angle), a culm sensor 43 that is provided in the cutting unit 4 to detect the presence or absence of culm, and a mission unit (not shown) are provided to control the vehicle speed. A vehicle speed sensor 44 (see FIG. 8) for detecting is provided, and the measured weight by the weight sensor 33 is corrected based on the detection results of the sensors 40 and 41, and the measured weight corrected based on the detection result of the moisture sensor 25 is used. I am trying to fix it.

  As shown in FIG. 8, the control unit 42 having a built-in timer is provided in the operation unit 9, and the moisture sensor 25, the weight sensor 33, the pitch angle sensor 40, the roll angle sensor 41, and the grain are provided on the input side of the control unit 42. While the saddle sensor 43, the vehicle speed sensor 44, and the display panel operation unit 45 are connected, a display panel unit 46 provided in the driving unit 9 is connected to the output side of the control means 42.

  In this manner, 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 grain in the Glen tank 20 can be estimated with higher accuracy.

  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 kernel detected by the moisture sensor 25, and the corrected weight is obtained as a yield (yield). As shown in FIG. 10, the weight of the grain, the moisture, and the harvest amount (yield) which is the corrected weight are displayed on the display panel unit 46. 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.

  Furthermore, as shown in FIG. 9, the field B is partitioned into a matrix, and the weight of the grain for each of the sections a1, a2,. Based on the moisture content of each grain detected by the sensor 25, the grain weight at the specified moisture value is corrected, and the corrected weight is displayed on the display panel 46 as a harvest amount. (See FIG. 10).

  That is, as shown in FIG. 9, the section of the farm field B is a movement process of the vehicle body during the harvesting operation, for example, the harvesting operation is performed while the vehicle body is advanced from the end position on the left side of the farm field B, and the left side of the farm field B Rotate at the end position beyond (a), perform the cutting operation while moving the vehicle body from the end position on the right side of the field B, and rotate at the end position between the right side of the field B. (B) The cutting operation is carried out 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 end on the right side of the field B. The cutting operation is performed while the vehicle body is moved forward from the position of the vehicle, and the cutting operation is performed at the end position of the right hand of the field B (D), and the cutting operation is performed while the vehicle body is advanced from the position of the left front of the field B. And turn around at the end of the field B beyond the left side (e) The cutting operation is performed while the vehicle body is advanced from the end position on the right side, and the vehicle body is advanced from the end position on the right side of the field B (f), and the vehicle body is advanced from the end position on the front side of the field B. While doing this, perform the cutting operation.

  In this way, when performing the cutting operation while moving the vehicle body in a spiral shape, one section is set from the cutting width (vehicle body width) W and a predetermined moving distance L (for example, 10 m), and the entire field B is set. Create a matrix.

  Here, the above-described grain culm sensor 43 is configured to recognize the start of cutting and reaping in the reaping operation process by detecting the presence or absence of the culm of the crop.

  The vehicle speed sensor 44 detects the rotational speed of the transmission shaft of the transmission unit so as to obtain the moving speed and moving distance L of the vehicle body.

  Furthermore, from the time when the weight of the grain stored in the Glen tank 20 is detected, the time (for example, 15 seconds) from the start of the cutting operation until the grain is stored in the Glen tank 20 is subtracted. By making such a correction, the yield of points that passed before that time is not counted.

  As shown in FIG. 10, the display panel unit 46 displays a map M similar to the matrix field B. The map M can be any of the weight, moisture, and yield (yield) of grain. The map is selectively displayed as a map, and is displayed in a color-coded manner according to the shade of the color according to the local numerical value of each section, and the operator can easily view the map M To be able to grasp the situation.

  That is, when confirming any of the weight, moisture, and yield (yield) of the grains 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 unit 46. By pressing a required switch, a map M selected by switch operation can be displayed on the display panel 46 from among the weight, moisture, and yield (yield) of the grain. By visually recognizing desired crop harvesting information locally and surely for each of the sections a1, a2,..., It is possible to accurately recognize the harvesting situation of the entire field B. ing.

  Moreover, as a calibration formula of the grains stored in the Glen tank 20, any of the following formulas can be appropriately employed.

[First calibration formula]
W = aX + b
W: Grain weight (kg), X: Output of weight sensor 33 (V)
The first calibration formula is a calibration based on the moving average of the weight sensor 33 without performing correction based on the detection results of the pitch angle sensor 40 and the roll angle sensor 41.

[Second calibration formula]
W = aX + bP + cR + dV
W: Grain weight (kg), X: Output of weight sensor 33 (V),
P: Pitch angle, R: Roll angle, V: Speed The second calibration equation is calibrated from the output value of the weight sensor 33 and the moving average of the detected pitch angle, roll angle, and vehicle body speed. Is.

[Third calibration formula]
ΔW = (a × ΔV1) + (b × Pa) + (c × Ra)
△ W: Section increase in grain mass in Glentank 20 (kg)
ΔV1: Increase in section of weight sensor 33 (V)
Pa: Section average value of the pitch angle Ra: Section average value of the roll angle The third calibration formula is performed by correcting the pitch angle, roll angle, and vehicle body speed detected for each predetermined section. It is.

  In the present embodiment, the correction is performed according to a predetermined correction formula based on the experience value.
