Further, as the shutter device 53, a regulating pin 62 is provided on the supply path 48 to regulate the opening/closing operation of the shutter member 58 at a predetermined position. Specifically, when the shutter member 58 is rotated upwardly by the drive motor 59 to the closed state where the supply path 48 is closed, the regulating pin 62 is used to prevent the shutter member 58 from moving upwardly. When the shutter member 58 is rotated downwardly by the drive motor 59 toward the side that opens the supply path 48, the upper rotation regulating pin 62A restricts the rotation, and the further downward movement of the shutter member 58 A downward rotation regulating pin 62B for regulating rotation is provided.

According to this configuration, the storage type measuring device 52 first closes (the lower part of) the supply path 48 by switching the shutter member 58 of the shutter device 53 to the closed state, thereby removing the supply path 48 from the opening 45. The grains falling above are temporarily dammed up and stored on the supply path 48. That is, a part of the supply path 48 can be made to function as a storage section that temporarily stores grains for grain quality measurement.

Thereby, when the sampling grain detection sensor 56 detects that the number of grains stored on the supply path 48 has exceeded a predetermined amount, the control unit 50 controls the imaging device 54 etc., it is configured to measure the quality of the grains stored on (the storage section of) the supply path 48.

It is configured so that it can be supplied to the moisture meter 51 side in grain units. At this time, the sampling device 63 arranged on the supply route 48 is arranged upstream of the supply route 48 than the shutter member 58 (specifically, the storage section in which grains are stored by the shutter member in the closed state). is configured to be

At this time, the discharge section 66 is configured to be arranged downstream of the supply path 48 than the shutter member 58 (see FIG. 7).

Furthermore, the single particle measuring device 51 configured as described above 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 start measuring (inspecting) the quality of the grains by the moisture meter 51. Thereby, the grains whose quality is measured by the single-grain measuring device and the storage-type measuring device can be grains whose quality has been threshed at approximately the same timing.

The discharge port 47 is provided at the lower end side of the grain measuring unit 40 and is used to collect grains that fall when the shutter member 58 is switched to the open state and grains that are discharged from the discharge section 66 of the moisture meter 51. This is a discharge path that merges the grains with each other, and is configured so that the measured grains can be discharged from the lower end side of the grain measuring unit.

Note that the grains discharged from the discharge port 47 of the grain measuring unit 40 are discharged not to the grain tank 7 side but to the handling chamber 23 side, and are re-sorted by the sorting section 23 of the threshing device 6. It is configured so that the work is performed (see FIG. 5). According to this configuration, for example, even if the moisture meter 51 is used to crush and measure grains to be measured, crushed or ground grains may not be present in the grain tank 7. can be prevented from being stored.

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

Further, the grain measuring unit 40 includes the opening 46 for supplying grain to each grain measuring device 51, 52 that measures grain quality, the supply path 48, and the discharge part 47. By standardizing the parts, the number of parts can be reduced and manufacturing costs can be kept lower.

In addition, the grain measurement unit 40 uses the opening 46 and the discharge part 47 in common, and separates the grains put into the opening 46 into each grain measuring device (single grain measuring device 51). - A supply route for supplying the storage type measuring device 52) is configured separately, and configured so that the grains measured by each grain measuring device 51, 52 and later discharged are reunited at the discharge section 47. Also good.

Incidentally, in the illustrated example, the grain measuring unit 40 is constructed by unitizing a plurality of (in the illustrated example, two) grain measuring devices 51 and 52, so that the grain measuring unit 40 can be connected to the main body case 36 (grain transport device 33). ), but the single-grain measuring device 51 and the storage-type measuring device 52 are separately installed in the main body case 36 (grain conveying device 33). It may be configured to be attached to.
It may be.

Further, in the illustrated example, the grain measuring unit 40 is installed removably in the grain conveying device 33, but the grain measuring unit 40 is installed in the grain tank 7. It may be configured.

Next, grain quality measurement control by the control section will be explained based on FIGS. 8 and 9. FIG. 8 is a block diagram of the control section. Connected to the output side of the control section (control device) 50 are the drive motor (shutter drive means) 59, an external server 67 connected via a communication section to be described later, and a liquid crystal monitor 68.

On the input side of the control unit 50, there is a running detection means 71 that detects the vehicle speed (running state) of the running body using a vehicle speed sensor, a potentiometer that detects the swinging position of a main shift lever (not shown), etc., and a power clutch switch. A reaping/threshing drive detection means 72 detects the driving status of the reaping section 3 and the threshing device 6 using a clutch on/off detection sensor of the threshing device, etc., and detects the presence or absence of the reaped grain culm being transported rearward by the reaping section 3. a grain culm detection means 73 for detecting whether or not reaping (harvesting) work is in progress; the shutter position detection means 61; the sampling grain detection means 56; and the moisture meter (moisture sensor) 51. , the photographing means (camera) 54 is connected to an aircraft position detecting means 74 consisting of a GNSS unit (GPS unit) or the like that obtains position information of the traveling aircraft from a positioning satellite.

The control unit 50 also includes a data storage unit 76 that stores information acquired by each grain measuring device (various sensors), etc., and information such as grain quality measurement results stored in the data storage unit 76. and a communication section 77 for transmitting the information to the external server 67.

Thereby, the control unit 50 transmits the image data of the harvested grains acquired by the grain measurement unit 40, the grain moisture content, the position information of the place where the grains were acquired, and other related information to the It can be stored in the data storage section 76 and transmitted to the external server 67 via the communication section 77. The external server 67 can analyze information such as accumulated image data in more detail and quantify or graph grain quality.

It is configured. The liquid crystal monitor 68 may be configured to output the analysis results from the external server 67.

Next, the grain quality measurement control will be explained based on FIG. FIG. 9 is a flow diagram showing grain quality measurement control. When the processing flow of the grain quality determination control is started, the process proceeds to step S1. In step S1, it is determined whether or not the combine harvester is in the process of reaping and threshing (harvesting) the grain culm by using the traveling detecting means 71, the reaping/threshing drive detecting means 72, and the grain culm detecting means 73. If it is detected and it is confirmed that the combine harvester 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.

Note that if the closed state of the shutter member 58 is not detected in step S2, the process advances to step S3. In step S3, the shutter member 58 is driven to close 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 brought into the closed state by the shutter position detecting means 61.

In step S4, the moisture meter 51 starts measuring the moisture content of the grains, and then the process proceeds to step S5.

In step S5, the amount of grains stored on the supply path 48 (storage section) by closing the shutter member 58 and damming the supply path 48 using the sampling grain amount detection means 56. If it is detected whether or not the amount of grains has exceeded a predetermined amount, 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.

In addition, in step S5, when the amount of grains equal to or more than a predetermined amount is not detected on the supply path 48, the process returns thereafter.

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

In step S7, the measurement of grain moisture content by the moisture meter 51 is finished, and 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 measuring device) 51 and the photographing means 54 (storage type measuring device 52), position information data of the traveling aircraft 2 acquired by the GPS device 74 etc. etc. are stored in the data storage section 76 of the control section 50, and then the process proceeds to step S9.

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

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

As described above, when the various sensors 71, 72, and 73 detect that the combine harvester is in the process of harvesting, the control unit 50 causes the grain measuring unit 40 to perform grain sampling and grain quality measurement. is automatically started, and when the storage-type measuring device 52 finishes photographing the grains, the grain quality measurement is also automatically ended.

Note that if it is not detected in step S1 that the combine harvester is in the process of harvesting, the process advances to step S11.

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

Note that 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 swinging position is stopped halfway), the process proceeds to step S12. move on. In step S12, the shutter member 58 is driven by the drive motor 59 to be in an open state, and then the process proceeds to step S13.

In step S13, the moisture measurement of the grains by the moisture meter (single grain measuring device) 51 is finished, 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 grain quality measurement (moisture measurement) and closes the shutter member 58. is configured to automatically end the grain quality measurement when the is switched to the open state. Further, the control unit 50 causes the data storage unit 76 to store the measured values for each grain and the average value thereof, which are measured while the shutter member 58 is switched to the closed state.
