Is provided. Moreover, you may mount | wear with other working machines, such as a knotter which binds a waste, behind the cutter apparatus 19 of this Example.

  When the grain amount in the Glen tank 16 is full, the grain is discharged from the milled cylinder 20 and the grain discharge auger 21 to the outside of the machine. The whipping cylinder 20 is configured to be turnable by an electric motor (not shown), and the grain discharge auger 21 is configured to be moved up and down by a hydraulic cylinder 22. And the grain discharge auger 21 is connected with the upper part of the whipping cylinder 20, and is comprised integrally, and when the whipping cylinder 20 turns, the grain discharge auger 21 also turns together.

  Further, the combine determines the position of the sub-shift in the travel transmission device 17 by operating the sub-transmission lever 23 provided in the operation unit 13, and then operates the travel shift lever 24 to drive power from the engine (not shown). Is transmitted to the left and right crawler type endless track zones of the traveling device 1 via a hydraulic continuously variable transmission (not shown) and the traveling transmission device 17 to travel at an arbitrary speed. As described above, the speed is changed by the operation amount of the traveling speed change lever 24, and the combine is moved forward and backward by the forward and backward operations of the traveling speed change lever 24.

  The combine is configured to turn left and right by tilting the steering lever 14 provided in the operation unit 13 in the left-right direction, and further, the turning radius depends on the amount of tilting operation of the steering lever 14 in the left-right direction. It is a configuration to be determined.

  When the harvesting operation is performed by advancing such a combine, the cereals planted in the field scene are weeded by the weeding tool 4, and then caused by the pulling device 5 and by the cutting blade 6. It is a structure that is reaped. Thereafter, the harvested cereals are transported rearward by the stock transporter 8 and transferred to the supply transporter 10. The cereal that has been handed over to the supply and transport device 10 is further transported rearward and is handed over to the feed chain 15 of the threshing device 9, and the cereal is transported rearward by the feed chain 15 to the threshing device 9. And threshing and sorting.

  The grain thus threshed and sorted is conveyed from the first cereal cylinder 26 into the Glen tank 16 and temporarily stored. When the amount of the grain stored in the Glen tank 16 is full, the operation unit In this configuration, 13 notification means (buzzer or display device) notify the operator. Thereafter, the cutting operation is interrupted, and the operation for discharging the grains in the Glen tank 16 to the outside of the machine is started. The combine is moved to an arbitrary position (position near the truck), the grain discharge auger 21 is detached from the auger receiver 27, and the grain discharge port 21a is moved to a position such as a truck bed. Then, the grain discharge lever 28 provided in the operation unit 13 is turned on, the grain in the Glen tank 16 is discharged to the outside of the machine, and when the grain discharge in the Glen tank 16 is finished, the grain discharge auger Reference numeral 21 denotes a configuration in which the auger receiver 27 is stored again.

The operation unit 13 is provided with display means 29 (hereinafter referred to as a liquid crystal monitor or a monitor) for displaying various information.
The display on the monitor 29 is configured to display as shown in FIG. 3 in a normal working state. That is, as shown in FIG. 4, the threshing clutch sensor 30 is in the engaged state, the culm sensor 31 provided in the reaping device 3 is in the engaged state, and the vehicle speed sensor 32 provided in the traveling transmission device 17 is more than a predetermined value. When the speed is detected, the controller 100 recognizes that the cutting operation is being performed, and the monitor 29 is configured to display as shown in FIG. 3 ( first display screen A).

  The display content in this case is to display the ratio of the engine load 33 (work load), the Glen tank dredging display 34, the combined use time 35, and the fuel remaining amount 36. The combine use time 35 may be switched to display the combine vehicle speed. This makes it possible to easily recognize important information during the cutting operation. FIG. 13 shows an embodiment in which the combine vehicle speed (cutting travel speed) is displayed.

In addition, when the combine is turning during the non-reaping operation, in particular, only the dredging amount display 34 in the Glen tank 16 is preferentially displayed ( second display screen B). Further, as shown in FIG. 5, when the dredging amount in the Glen tank 16 is nearly full, a character display 37 indicating that the Glen tank will soon be full is also displayed ( second display screen B). In addition, as shown in FIG. 6, when the amount of soot in the Glen tank 16 is full, a display 38 for prompting soot discharge is also displayed. Regarding conditions for the combine to travel, the grain clutch sensor 30 is in the on state, the grain sensor 31 provided in the reaping device 3 is in the cut state, and the vehicle speed sensor 32 provided in the traveling transmission device 17 is predetermined. This is a case where the above speed is detected.

  Thereby, for example, when turning over, if the amount of dredging in the Glen tank 16 is missed at the time of turning, after entering the next cutting line, the full amount state is noticed and the cutting operation must be interrupted and the discharging operation must be performed. However, such a problem can be prevented. Further, at the time of turning, the fuel remaining amount display 36 may be displayed together. As a result, when the amount of fuel is low during turning, refueling can be performed to prevent the fuel from becoming empty after entering the next cutting line.

  In the monitor 29, a color liquid crystal may be used. In the case of a color liquid crystal, when urging the grain in the glen tank 16 or urging the fuel to be replenished, it is easier for the operator to recognize by using a color such as yellow. In addition, when it is necessary to promptly cope with a rise in the water temperature sensor, a decrease in engine oil, etc., it is possible to prevent damage by notifying in red or the like.

  In the case of a color liquid crystal, a CCD camera is provided on the front and rear of the combine body, the harvesting unit, the threshing device, the takeover of the transporting culm, and the like. It may be configured. This image switching is basically performed manually, but when there is an abnormality in various sensors arranged in the vicinity of the CCD camera, it is automatically located closest to the sensor having the abnormality. Take a picture of the CCD camera.

Thereby, the operator can easily recognize the abnormal state.
The detection of the amount of straw in the Glen tank 16 is configured to be performed by the Glen tank grain level sensor 39. In this embodiment, five Glen tank grain level sensors 39 are provided at predetermined intervals. It is said. No. 5 is a full sensor.

  As shown in FIG. 7, a discharge clutch sensor 40 and an engine rotation sensor 41 are connected to the controller 100. That is, while the soot in the Glen tank 16 is being discharged to the outside of the machine, the discharge clutch sensor 40 is in the engaged state and the engine is raised to approximately the rated speed, so the engine rotation sensor 41 is equal to or higher than the predetermined rotation speed. Is detected.

  During the so-called soot discharging operation in such a state, the display as shown in FIG. That is, the soot amount 40 in the Glen tank discharged every moment is displayed. Furthermore, as shown by 41, the time until the discharge is completed and the remaining time as shown by 42 are displayed in a bar display. This facilitates preparation for the next operation.

  As for the time 41 until the discharge is completed, the count is stopped when the discharge is interrupted in the middle, and the count is restarted when the discharge is restarted. In addition, when the operation is shifted to the cutting operation after the discharge is interrupted, the count is reset and the display on the monitor 29 is switched to the display as shown in FIG. Further, when the time 41 until the discharge is completed becomes zero, the display of the discharge time 41 may be terminated and only the soot amount display 34 in the Glen tank may be displayed as shown in FIGS. .

  The first display of the time 41 until the discharge is completed displays a standard discharge time determined by the machine, and from the next time, the time until the discharge is completed is displayed based on the first total discharge time. Thereby, efficient work is possible. Further, the time 41 until the completion of the discharge may be corrected by an actual engine speed. Moreover, you may comprise so that the time 41 until discharge completion may be correct | amended and displayed from the change state of the five Glen tank grain level sensors 39 provided.

  Although a plurality of (5 in the embodiment) Glen tank grain level sensors 39 are provided, the upper sensor is in the on state and the lower sensor is in the cut state during the discharging of the straw. In such a case, it is recognized that a cavity is generated inside, and vibration is applied to the Glen tank 16. As shown in FIG. 9, the vibration rotates the cam below the Glen tank so as to strike the Glen tank 16. As a result, the lump 44 of the cocoon collapses and the potato can be discharged.

  However, when the moisture value of the cocoon is high, the cocoon lump 44 often does not collapse, so it is displayed on the monitor 29 as shown in FIG. 10 to notify the operator. Thus, time loss can be reduced and efficient work can be performed.

  FIG. 11 is a schematic view of the combine as viewed from above. The grain discharge auger 21 has a movable cylinder 46 fitted to a fixed cylinder 45, and the movable cylinder 46 is configured to be movable in the longitudinal direction. That is, since the grain outlet 21 a is provided at the tip of the moving cylinder 46, the grain outlet 21 a is configured to move in the longitudinal direction together with the moving cylinder 46. And when discharging | emitting a grain to the loading platform etc. of the truck 47, discharge | emission of a grain becomes easy by combining turning of the grain discharge auger 21 and the movement to the longitudinal direction of the movable cylinder 46. FIG.

  However, particularly in a large combine or the like, there is a problem that it is difficult to position the grain outlet 21a on the loading platform of the truck 47 when the amount of expansion and contraction of the movable cylinder 46 is not known.

  Therefore, when the extension switch 48 and the shortening switch of the moving cylinder 46 provided in the control unit 13 are operated, the moving amount (zoom amount) of the moving cylinder 46 is displayed on the monitor 29. FIG. 12 shows an example of this display. The grain amount in the Glen tank 16 is displayed on the left side of the monitor 29, and the movement amount (zoom amount) of the moving cylinder 46 is displayed on the right side of the monitor 29.

  Thereby, kernel discharge | emission becomes feasible easily. In particular, when the moving amount of the moving cylinder 46 is insufficient, the necessity of moving the machine body can be grasped in advance, so that efficient work can be performed.

  As described above, when the moving amount (zoom amount) of the moving cylinder 46 is displayed on the monitor 29, the moving amount of the moving cylinder 46 can be reduced by displaying the bar graph 50 and displaying the ratio 51 (% display). It can be easily recognized. In this case, the most contracted state of the movable cylinder 46 is set to 0%. The display on the bar graph 50 and the display on the ratio display 51 (% display) may be displayed together or may be configured to be displayed separately.

  In the movement amount (zoom amount) display of the moving cylinder 46, it may be detected continuously by a position sensor, or may be displayed in stages at predetermined intervals. In the case of the stage display, the moving amount (zoom amount) of the moving cylinder 46 may be detected by a position sensor, or may be detected by a limit sensor provided at predetermined intervals.

  As described above, the monitor 29 is configured so that various displays can be performed. However, in an emergency, for example, when the water temperature becomes abnormally high (overheating) or when the engine load increases abnormally ( In the case of clogging, etc., priority is given to these abnormal indications. Alternatively, the traveling of the combine is automatically stopped or decelerated.

  Each of the above-described embodiments is illustrated or described separately or mixed for easy understanding, but these can be combined in various ways, and can be configured according to their description order and expression. -The action and the like are not limited, and there are of course cases where a synergistic effect is produced.
