An embodiment of the present invention will be described with reference to the drawings of the combine. 1 is a fuselage frame of the combine, 2 is a traveling device provided below the fuselage frame 1, 3 is a threshing device provided above the fuselage frame 1, and 4 is a threshing device. 3 is a grain tank provided on the side of the threshing device 3, 6 is a discharge graining device connected to the terminal of the discharge device 7 of the grain tank 5, and 8 is a discharge graining device 6. A discharge auger provided on the top of the discharge auger 8 is configured such that the tip of the discharge auger 8 can be swung vertically and vertically with respect to the discharge cerealing device 6. A control unit 10 is provided on the front side of the Glen tank 5. In FIG. 1, the control unit 10 is formed in a so-called cabin 11 that surrounds the driver's seat, but it does not have to be enclosed by the cabin 11 as shown in FIG. 2.
The grain tank 5 is connected to an upper outlet 13 of a cerealing device 12 connected to a first conveyor (not shown) of the threshing device 3, and temporarily stores the grains threshed by the threshing device 12. A plurality of storage amount detection sensors 14 for detecting the storage amount of the grain are arranged in parallel in a predetermined position in the Glen tank 5.
Further, a flow rate sensor 15 is provided in the vicinity of the upper outlet 13 of the cerealing device 12 (in the vicinity of the portion where the grains flowing from the upper outlet 13 are scattered). The flow rate sensor 15 counts the number of grains to detect the flow rate, thereby correcting the height position sensed by the storage amount detection sensor 14 and calculating the storage amount of the Glen tank 5. Although the configuration of the flow sensor 15 is arbitrary, in the embodiment, it is configured by a so-called shock sensor, and the flow rate is detected by counting the number of grains hitting the flow sensor 15.

The signal of the storage amount detection sensor 14 and the signal of the flow rate sensor 15 are transmitted to the controller C, and the controller C that receives this signal calculates the grain amount and displays it in the Glen tank 5 on the display monitor 17 provided in the control unit 10. The amount of storage is displayed.
That is, even if the working time is the same, the working efficiency of the threshing device 3 changes depending on the field conditions and grain conditions (moisture content, etc.), and naturally the change in the working efficiency of the threshing device 3 leads to the Glen tank 5. Although the flow rate also changes and the detection accuracy of the storage amount detection sensor 14 may differ depending on the installation position of the storage amount detection sensor 14, the grain height among the plurality of storage amount detection sensors 14 may be different. Based on the sensing position and the flow rate of the flow rate sensor 15, the amount stored in the Glen tank 5 is calculated comprehensively, and the status in the Glen tank 5 is accurately displayed on the display monitor 17.
In other words, when grains are stored in the Glen tank 5, the storage amount detection sensor 14 in which a plurality of the grains are arranged in the vertical direction is detected, and the inside of the Glen tank 5 where the storage amount detection sensor 14 is not provided. The amount of stored water is estimated from the signal of the flow sensor 15 that can detect the amount of grain that flows into and scattered in the Glen tank 5, and as a result, the height position of the stored amount sensor 14 is corrected to reduce the amount of stored water in the Glen tank 5. Calculation is performed, and the amount stored in the Glen tank 5 is displayed on the display monitor 17 provided in the control unit 10.
For example, in the conventional example of FIG. 4, the grain is collected on the side near the upper discharge port 13, and even if the grain is contained up to a height at which the third level storage amount sensor 14 is turned on when leveling, Although the display on the monitor 17 is the second stage display, in the present application, the display monitor 17 makes the third stage display by correcting the flow rate by the flow sensor 15 even when the third stage storage amount sensor 14 is off. , Improve display accuracy.

Thus, the future work in which the Glen tank 5 becomes full by adding the running speed detected by the vehicle speed sensor 18 to the current grain amount in the Glen tank 5 by the storage amount sensor 14 and the flow sensor 15. The work distance traveled until the time or the remaining full is calculated and displayed on the display monitor 17.
That is, the future grain processing amount is estimated by adding the traveling speed to the accurate grain amount in the grain tank 5, and how far the grain tank 5 will be filled when working in the future. By displaying as a guide (distance display and / or time display), operability is improved.
Although the display on the display monitor 17 in this case is arbitrary, FIG. 5 shows the working distance until full and the working time until full, and FIG. 6 shows the remaining working distance until full in parallel. Any of these may be displayed, or each of them may be switched and displayed on the display monitor 17.

7 and 8, the second object sensor 22 is provided in the second object processing device 21 for processing the second object from the second conveyor 20 of the threshing device 3, and this second object sensor 22 is provided. The second product processing amount of the second product processing device 21 calculated by the following equation is used to calculate the traveling speed detected by the vehicle speed sensor 18 and the current grain amount data in the grain tank 5 by the storage amount sensor 14 and the flow rate sensor 15. In addition, it is configured to calculate the future work time (travel distance for work) when the Glen tank 5 becomes full.
That is, in the first embodiment, the flow rate sensor 15 is added to the storage amount detection sensor 14 to improve the calculation accuracy of the grain amount in the Glen tank 5, but in this embodiment, the second sensor 22 is further used.
