Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is a combine harvester that detects the amount of harvested grain in the direction in which the machine heads toward the grain discharge position during the harvesting work process.
The present invention relates to a device for informing whether or not grain should be discharged in the work process.

(Prior Art) Conventionally, in a grain tank combine harvester, a grain tank that stores harvested grains is equipped with a grain amount sensor, and an alarm is issued when the grain tanks are fully or nearly filled in the grain tank during harvesting work. Those that emit are known and have been put to practical use.

(Problems to be Solved by the Invention) In a grain harvesting operation using a combine harvester, it is convenient and efficient that the grain discharge position at which the harvested grain is loaded onto a road truck is constant. However, in the conventional combine as described above, during the harvesting process,
The position where the warning that the Glen Tank reaches the full amount or near the predetermined amount is issued is not constant, so that the position is far from the grain discharge position, or the aircraft is moving away from that position. For this reason, the harvesting work must be interrupted once, and then the machine body must be detoured or the traveling direction must be changed to move to the grain discharge position, which causes a reduction in the harvesting work efficiency.

(Means for Solving Problems) Therefore, the present invention provides a direction sensor for detecting the traveling direction of the machine body, a grain amount sensor for detecting the amount of harvested grains, and data of the direction sensor and the grain amount sensor. Equipped with a processing device that processes and sends out a notification signal and a storage device that stores the direction data when the harvested grain is discharged, and the grain amount when the direction data read during the progress of the aircraft matches the storage data of the storage device. And the grain amount notification signal is transmitted, and at that time, the predicted grain amount is calculated by adding the current grain amount and the harvested grain amount predicted in the next process, and the predicted grain amount is calculated. Further, by configuring so as to send the amount notification signal, the predicted grain amount is calculated by adding the harvested grain amount predicted in the next process to the current grain amount, and the predicted grain amount reaches the storage limit. If it exceeds, an emission notification signal will be sent. With this configuration, the above problems are to be solved.

(Operation) In the harvesting work process, the traveling direction of the machine is detected by the direction sensor, the amount of harvested grain is detected by the grain amount sensor, and the direction of the machine at the time of discharging the harvested grain is stored in the storage device. Then, during the progress of the aircraft in the harvesting work process, when the orientation matches the stored orientation data, that is, when the traveling direction of the aircraft becomes the orientation of the aircraft at the time of discharging the harvested grain, the first In the case of the configuration of No. 3, the grain yield at that time is notified, in the case of the second configuration, the estimated amount of grain obtained by adding the expected harvest of the next process to the current amount of grain is informed, and in the third configuration Then, when the predicted grain amount exceeds a preset storage limit, it is notified that the grain is being discharged.

The discharge notification position as described above is in a state where the traveling direction of the machine body is directed to the harvested grain discharge position. Therefore, in the first and second configurations, the work vehicle judges the discharge time, and With the third configuration, when the discharge notification is issued, the aircraft can be moved to the harvested grain discharge position in the same direction in the optimum short distance as it is.

It is also possible to have a function of sending (not shown). Here, the discharge notification is made by a language based on a voice synthesis signal, a buzzer sound, a lamp lighting, or the like.

Next, the operation of each embodiment configured as described above will be described.

FIG. 8 is a flow chart of the first embodiment, but the flag registers (FG ₁ ) and (FG ₂ ) of the central processing unit 22 are shown.
The initial value of is set to "0", and the direction sensor 20 when the harvested grain is discharged
Direction data (D ₁ ), direction sensor in the harvesting process
The initial values of the 20 azimuth data ((D ₂ ) are both set to “0.” The grain discharge notification device starts and it is determined whether the flag register (FG ₁ ) is “1”. If the discharge lever 14 is operated to the discharge side and the switch 18 is closed, the direction data of the direction sensor 20 at that time (D ₁ )
Is read and stored in the storage device 28. Then, the flag register (FG ₁ ) changes to “1”. The stored bearing data (D ₁ ) is the bearing of the aircraft when the harvested grain was discharged. After discharging the harvested grain, when the aircraft moves to the next harvesting process,
The azimuth sensor 20 detects the azimuth data (D ₂ ),
When the direction data (D ₂ ) matches the direction data (D ₁ ) and the flag register (FG ₂ ) is not "1", the data of the grain amount sensors 21a to 21d are read in the central processing unit 22, and The amount of grains in the Glen tank 4 is calculated. Then, a grain amount notification signal is sent based on the calculated grain amount,
The voice synthesizing unit 26 operates and the speaker 27 notifies the grain amount. At this time, the flag register (FG ₂ ) becomes "1". If the flag register (FG ₁ ) is “1” and the direction data (D ₁ ) at the time of discharging the harvested grain has already been read, only the direction sensor 20 data (D ₂ ) due to the progress of the aircraft will be available. Read. When the direction data (D ₂ ) of the direction sensor 20 is different from the direction data (D ₁ ), that is, when the gathering aircraft does not match the direction of the harvested grain discharge, the data of the grain sensors 21a-21d It is not read and the grain amount is not calculated. If the flag register (FG ₂ ) is “1”, that is, the direction of travel of the machine is in the same direction as when the harvested grain was discharged, and after the grain quantity is notified, the machine is traveling in that direction. The quantity notification is not repeated.

FIG. 9 is a flow chart of the second and third embodiments. In this embodiment, when the orientation data read during the progress of the aircraft matches the storage data of the storage device, the predicted grain amount is calculated by adding the current grain amount and the harvested grain amount predicted in the next process, and the prediction is performed. The amount of grains is reported, or the emission is notified when the predicted amount of grains exceeds the storage limit. For this reason,
As the interruption process, the vertical and horizontal distances of the field are calculated, and the harvested grain amount per unit time is calculated.

That is, when the "interrupt processing 1" is instructed in the harvesting process and the handling depth main sensor 30 is closed, the timer 31 is started, the bearing data of the bearing sensor 20 is read, and the vehicle speed sensor is read.
29 vehicle speed data is read. When the handling depth main sensor 30 is opened, the timer 31 is stopped, and after the travel distance is calculated, the timer 31 is cleared. By performing this process twice, the vertical and horizontal distances of the field are calculated and stored in the storage device 28. This operation ends after the processing is performed twice. Further, when "interrupt processing 2" is instructed and the handling depth main sensor 30 is closed, the timer 31 is started, and when the handling depth main sensor 30 is opened, the timer 31 is stopped. This operation is repeated until the discharge lever 14 is discharged and the switch 18 is closed. Then, when the switch 18 is closed, the data of the grain amount sensors 21a to 21d are read, and the grain amount harvested per unit time is calculated. The calculated grain amount per unit time is stored in the storage device 28, the timer 31 is cleared, and the operation ends.

Also in this embodiment, the initial values of the flag registers (FG ₁ ) and (FG ₂ ) of the central processing unit 22 are set to “0”, the orientation data (D ₁ ) of the orientation sensor 20 at the time of discharging the harvested grains, the harvesting work process. The initial values of the azimuth data (D ₂ ) of the azimuth sensor 20 are set to "0". When the grain discharge notification device starts, it is determined whether the flag register (FG ₁ ) is "1", it is not "1", the discharge lever 14 is operated to the discharge side, and the switch 18 is closed. The azimuth data (D) of the azimuth sensor 20 is read and stored in the storage device 28.
Then, the flag register (FG ₁ ) changes to “1”. The stored bearing data (D ₁ ) is the bearing of the aircraft when the harvested grain was discharged. After the harvested grain is discharged, when the aircraft shifts to the next harvesting stroke, the vehicle speed sensor 29 detects the vehicle speed data and the direction sensor 20 detects the direction data (D ₂ ).
When the orientation data (D ₂ ) matches the orientation data (D ₁ ) and the flag register (FG ₂ ) is not "1", the grain amount sensor 21a
~ 21d grain data is read. Then, it is determined whether the harvesting process is line cutting or round cutting, and the predicted grain amount is calculated by adding the predicted harvested grain amount of the next process under the condition corresponding to each case. In the second embodiment, the predicted grain amount notification signal is sent here, the voice synthesis unit 26 operates, and the speaker 27 notifies the grain amount. Further, in the third embodiment, it is judged whether the predicted grain amount exceeds the storage limit, that is, whether or not one more round is possible, and if it exceeds the limit, an emission notification signal is sent. The flag register (FG ₂ ) changes to “1” when the grain quantity notification signal or the discharge notification signal is sent. Calculation of the predicted harvested grain amount in the next step above
Travel distance x [m] calculated and stored in interrupt processing 1 and interrupt processing 2 and harvested grain amount y [kg per unit time]
/ min], and vehicle speed data v [m / min] of vehicle speed sensor 29
Is calculated as y × x / v [kg].

When the orientation data (D ₂ ) of the orientation sensor 20 is different from the orientation data (D ₁ ), that is, when the aircraft in progress does not match the orientation at the time of harvest grain discharge, the data of the grain sensors 21a to 21d are read. It is not rare and the grain volume is not calculated. If the flag register (FG ₂ ) is “1”, that is, the aircraft will move in the same direction as when the harvested grain was discharged, and after the predicted grain amount or discharge notification was issued, the aircraft would move in that direction. The forecasted grain amount or emission notification will not be repeated.

As is clear from the above actions, in the harvesting process,
As shown in FIG. 10, when the combine 1 in the field a is turned to the position of c ₁ , c ₂ ... Of the cutting path b, that is, the direction of the combine 1 at the harvested grain discharge position d, the current grain amount, the predicted grain amount or Since the discharge notification is made, the combine 1 can be moved to the harvested grain discharge position d in the shortest distance and while traveling forward. e is a road and f is a truck for transporting grain.

(Effect of the Invention) As described above, the present invention processes the data of the direction sensor that detects the traveling direction of the machine body, the grain amount sensor that detects the amount of harvested grains, and the data of the direction sensor and the grain amount sensor. However, the processing device that sends out the notification signal and the storage device that stores the orientation data when the harvested grain is discharged are configured such that the orientation data that is read while the aircraft is traveling is the storage orientation of the storage device. Calculate the grain amount when it matches the data,
In addition, it has a function of sending a grain quantity notification signal, and also has a function of calculating a predicted grain quantity by adding the current grain quantity and the harvested grain quantity predicted in the next process, and sending a predicted grain quantity notification signal. In addition, since it has a function of sending an emission notification signal when the predicted grain amount exceeds the storage limit, the grain storage unit such as the grain tank is filled to a predetermined amount or close to it during the harvesting process. The notification position of the arrival is always constant with respect to the harvested grain discharge position, and the direction of the combine at that position can be advanced toward the harvested grain discharge position, and the aircraft is shortest when discharging the harvested grain. It can be easily moved to a predetermined position by a distance. Therefore, according to the present invention, it is possible to obtain an effect that the grain harvesting work by the combine can be facilitated and the efficiency can be improved.
