At this time, the discharge unit 66 is configured to be arranged on the downstream side of the supply path 48 with respect to the shutter member 58 (see FIG. 7).

Further, the single grain measuring device 51 having the same configuration drives the sampling device 63 when the control unit 50 detects that the shutter member 58 has been switched from the open state to the closed state. It is configured to start supplying grains to the moisture meter 51 and measuring (inspecting) the quality of grains by the moisture meter 51. Thereby, the grains whose quality is measured by the single grain type measuring device and the storage type measuring device can be targeted for the grains which have been threshed at substantially the same timing.

It is configured to perform the work (see FIG. 5). According to the configuration, for example, even when the moisture meter 51 crushes and measures the grain to be measured, the crushed or ground grain is contained in the grain tank 7. It can be prevented from being stored in.

Further, in the illustrated example, the grain measuring unit 40 is vertically aligned so that the single grain measuring device 51 and the storage measuring device 52 connect the opening 46 and the discharge port 47. It is arranged so as to sandwich the supply path 48 formed in the left and right sides. With this configuration, since a plurality of (two in the illustrated example) measuring devices are arranged around the supply path so as not to wrap in a plan view, the entire grain measuring unit 40 can be configured more compactly. ..

Further, the grain measuring unit 40 includes the opening 46 for supplying grains to the grain measuring devices 51 and 52 for measuring the quality of grains, the supply path 48, and the discharging section 47. By standardizing the above, the number of parts can be reduced, so that the manufacturing cost can be kept lower.

In the grain measuring unit 40, the opening 46 and the discharging section 47 are shared, and the grains thrown into the opening 46 are measured by each grain measuring device (single grain measuring device 51). The supply path to be supplied to the storage type measuring device 52) is separately configured so that the grains measured by the grain measuring devices 51 and 52 and then discharged are rejoined by the discharging section 47. Is also good.

In addition, the control unit 50 has a data storage unit 76 that stores information acquired by each grain measuring device (various sensors) and the like, and information such as grain quality measurement results stored in the data storage unit 76. Has a communication unit 77 for transmitting the data to the external server 67.

As a result, the control unit 50 obtains image data of the harvested grains acquired by the grain measurement unit 40, grain water content, position information of the place where the grains are acquired, and other related information. It can be stored in the data storage unit 76 and transmitted to the external server 67 via the communication unit 77. The external server 67 can analyze the accumulated information such as image data in more detail, and digitize or graph the grain quality.

Further, the control unit 50 can output the product measurement result of the harvested grains acquired by the grain measurement unit 40 to the liquid crystal monitor 68 connected by wireless communication or wired communication. It is configured. The liquid crystal monitor 68 may be configured so that the analysis result by the external server 67 can be output.

Next, the grain quality measurement control will be described with reference to FIG. FIG. 9 is a flow chart showing grain quality measurement control. When the processing flow of the grain quality determination control is started, the process proceeds to step S1.

If it is detected and it is confirmed that the combine is in the process of harvesting, the process proceeds to step S2.

In step S2, the shutter position detecting means 61 detects whether or not the shutter member 58 is in the closed state, and if the closed state of the shutter member is confirmed, the process proceeds to step S5.

If the closed state of the shutter member 58 is not detected in step S2, the process proceeds to step S3. In step S3, the shutter member 58 is closed and driven by the drive motor 59, and then the process proceeds to step S4. At this time, the closing drive of the shutter member 58 is continued until the shutter member 58 is closed by the shutter position detecting means 61.

In step S4, the moisture measurement of the grain by the moisture meter 51 is started, and then the process proceeds to step S5.

In step S5, the amount of grains stored on the supply path 48 (reservoir) by using the sampled grain amount detecting means 56 to close the shutter member 58 and block the supply path 48. If it is detected whether or not the amount of grains exceeds a predetermined amount determined in advance and it is confirmed that more than a predetermined amount of grains are stored on the supply path 48, the process proceeds to step S6.

If the amount of grains equal to or greater than the predetermined amount is not detected on the supply path 48 in step S5, the process returns thereafter.

In step S6, since a sufficient amount of grains is secured in the supply path 48, the image data of the grains stored in the supply path (storage unit) is acquired by the camera (photographing means) 54. After that, the process proceeds to step S7.

In step S7, the measurement of the grain water content by the moisture meter 51 is completed, the average value of the results of measuring a plurality of grains is calculated, and then the process proceeds to step S8.

In step S8, in addition to the measurement results by the moisture meter (single grain type measuring device) 51 and the photographing means 54 (reservoir type measuring device 52), the position information data of the traveling machine 2 acquired by the GPS device 74 or the like. The related data such as the above is stored in the data storage unit 76 of the control unit 50, and then the process proceeds to step S9.

In step S9, the above-mentioned related data stored in the data storage unit 76 is transmitted to the external server 67 via the communication unit 77, and then the process proceeds to step S10. As a result, the external server 77 analyzes the grain quality based on the grain quality data measured by the grain measuring unit 40 transmitted via the communication unit 77 and the related data thereof. be able to.

In step S10, the drive motor 59 switches the closed shutter member 58 to the open state, and then returns. As a result, when the quality measurement of the grains by the grain measurement unit 40 is completed, the grains stored on the supply path 48 are discharged from the discharge unit 47 into the threshing device 6. Has been done.

As described above, when the control unit 50 is detected by the various sensors 71, 72, 73 that the harvesting operation is being performed by the combine, the grain measurement unit 40 performs grain sampling and grain quality measurement. Is automatically started, and when the photographing of the grain by the storage type measuring device 52 is completed, the grain quality measurement is also automatically ended.

If it is not detected in step S1 that the combine is being harvested, the process proceeds to step S11.

In step S11, the shutter position detecting means 61 detects whether or not the shutter member 58 is in the open state, and when the open state of the shutter member 58 (open state of the supply path) is detected. , Step S13.

If it is not detected in step S11 that the shutter member 58 is in the open state (the shutter member 58 is in the closed state or the swing position is stopped in the middle), step S12 is performed. move on. In step S12, the shutter member 58 is driven by the drive motor 59 so as to be in the open state, and then the process proceeds to step S13.

In step S13, the moisture measurement of the grain by the moisture meter (single grain type measuring device) 51 is completed, and then the process returns.

That is, when the shutter member 58 of the storage type measuring device 52 is switched to the closed state, the single grain measuring device 51 automatically starts the grain quality measurement (moisture measurement), and the shutter member 58 Is configured to automatically end grain quality measurement when switched to the open state. Further, the control unit 50 stores the measured value for each grain measured while the shutter member 58 is switched to the closed state and the average value thereof in the data storage unit 76.
