[Problems to be solved by the device]

 At the place, an extension tank is provided in the Glen tank so as to be movable up and down, and in the combine in which the grain storage volume in each tank can be changed, a vertical movement device is provided between the machine body and each traveling device. When the vehicle height adjustment function is provided by providing it, the following problems occurred. That is, for example, when carrying out work traveling in a wet field, the vehicle height of the combine is increased via the vertical movement device.In such a case, the extension tank is extended from the grain tank to the upper side, and If the grain storage capacity in each tank is increased to store a large amount of grain, the position of the center of gravity of the combine becomes high, and the left and right running devices are individually separated in the state where the body weight is high. When the aircraft is controlled and the aircraft is horizontally controlled, the left-right balance of the aircraft becomes poor, which makes the traveling of the aircraft extremely unstable, and also deteriorates the straightness and turnability when traveling in a wetland. In addition, when traveling on the road, the vehicle height of the combine is increased.In such a case, if the extension tank is extended upward from the Glen tank, the extension tank blocks the operator's view. There was a problem that driving safety deteriorated.

The present invention has been made in view of the above problems, and its purpose is to extend the extension tank from the Glen tank when the vehicle height is high when traveling in a wet field or on the road. It is to provide a combine harvester that can improve the straightness and turnability of the vehicle and can drive safely without causing a fall accident.

The flowchart shown in FIG. 5 is for controlling the extension of the extension tank 7 in the automatic mode, and it is determined whether the automatic extension switch 16 is in the ON operation at the start of the start (step S1). In the case of NO, that is, when the extension switch 16 is in the OFF state and the extension control of the extension tank 7 in the automatic mode is not performed, the control according to the flowchart of FIG. 6 described later is performed. If YES in step S1, it is determined in step S2 whether the amount of paddy in the grain tank 5 detected by the grain tank paddy sensor 11 is equal to or more than a certain amount. Only when a certain amount of paddy is stored in the Glen tank 5. In step S3, it is determined whether the vehicle height automatic switch 17 is turned on. If the result of this determination is NO, in step S4 the vehicle height sensor 9 detects the combined vehicle height is high. If not, in step S5, it is determined whether or not the auxiliary shift lever for controlling the speed change of the traveling device 2 is at the high speed position, that is, whether or not the combine is traveling at high speed on the road. If no, in step S6, it is determined whether the extension / retraction position of the extension tank 7 detected by the extension / retraction sensor 10 is in the extended position. If no, in step S7, The extension tank 7 is extended by the extension / retraction device 8. That is, if any of the determination results in steps S3 to S5 is NO, that is, the vehicle height automatic switch 17 is turned off, and the vehicle height detected by the vehicle height sensor 9 is low, and Only when the sub-transmission lever is not in the high speed position, and when the determination result in step S6 is YES, that is, when the extension tank 7 is not in the extended position, the extension in step S7 is performed. The tank 7 is bulged, and the other bulges are not. After that, in step S8, it is determined that the alarm switch 18 is turned on. If yes, the alarm device 19 is turned off in step S9, and if the determination result in step S6 is yes. When the extension tank 7 is already overhanging, that is, when the extension tank 7 is not overhanging, the process proceeds to step S8 without performing overhanging in step S7.

On the other hand, if the determination results in steps S3 to S5 are all YES, that is, the vehicle height automatic switch 17 is turned on, and the vehicle height detected by the vehicle height sensor 9 is high, When the auxiliary shift lever is located at the high speed position, it is determined in step S10 whether the extension / retraction position of the extension tank 7 detected by the extension / retraction sensor 10 is in the extension position, In the case of yes, that is, when the extension tank 7 is located at the overhanging position, in step S11, it is determined whether a predetermined amount of paddy is stored in the extension tank 7 and the extension paddy sensor 12 is turned on. If the judgment is No, that is, only when the amount of paddy in the extension tank 7 is less than or equal to a predetermined value, step S 1 In step 2, the extension tank 7 is stored in the extension / retraction device 8, and when the result in step S11 is NO, that is, when a predetermined amount of paddy is stored in the extension tank 7, the extension paddy sensor 12 is turned on. When the power is on, the alarm device 19 issues a warning in step S13, and the storage of the extension tank 7 in step S12 is stopped. Furthermore, after the processing in steps S9, 12, and 13 is performed, the process returns to step S1.

Next, a case where the determination result in step S1 is NO and the extension control of the extension tank 7 is performed in the manual mode will be described. In this case, as shown in the flowchart of FIG. 6, first, in step S14, it is determined whether the extension switch 13 is in the ON operation. If the determination result is YES, that is, the extension tank 7 When manually operating the overhang, it is determined in step S15 whether the vehicle height automatic switch 17 is turned on. If the result of this determination is NO, the vehicle height sensor 9 detects in step S16. It is determined whether or not the vehicle height of the combine is high, and in the case of No, in step S17, it is determined whether or not the extension tank 7 detected by the withdrawal sensor 10 is in the extended position. In step S18, the extension / retraction device 8 extends the extension tank 7 described above. That is, when the determination results in steps S15 and S16 are both negative, that is, the vehicle height automatic switch 17 is turned off, and the vehicle height detected by the vehicle height sensor 9 is low, and The extension tank 7 is extended in step S18 only when the determination result in step S17 is NO and the extension tank 7 is not in the extension position. Thereafter, in step S19, it is determined that the alarm switch 18 is turned on, and if yes, the alarm device 19 is turned off in step S20, and after step S20, the process returns to step S1. To be done.

On the other hand, when the determination results in steps S15 and S16 are both YES, that is, when the vehicle height automatic switch 17 is turned on and the vehicle height detected by the vehicle height sensor 9 is high, In step S21, an alarm is issued by the alarm device 19, and extension of the extension tank 7 by the retracting device 8 is stopped.

In addition, in the case of NO in step S14, that is, when the extension tank 7 is not extended in the manual mode by turning on the extension switch 13, the storage switch 14 is turned on in step S22. If it is determined whether the ON operation is performed and the result of this determination is NO, that is, if the extension tank 7 is not stored by the operation of the storage switch 14, the vehicle height automatic switch 17 is turned on in step S23. If the result of this determination is NO, in step S24, it is determined whether or not the vehicle height of the combine at which the vehicle height sensor 9 is detected is high, and if NO, then from step S19. Is controlled. Furthermore, when the determination results in steps S22, 23, and 24 are all YES, that is, when the storage switch 14 is turned on or when the storage switch 14 is turned off, the vehicle height automatic switch 1 7 is turned on, or when the vehicle height detected by the vehicle height sensor 9 is high, in step S25, a predetermined amount of paddy is stored in the extension tank 7 and the extension paddy sensor 12 is operated. It is determined whether the ON operation is performed, and when the result is NO, that is, when the amount of paddy in the extension tank 7 is less than or equal to a predetermined value, in step S26, the extension / retraction device 8 stores the extension tank 7, and In the case of No in step S25, that is, a predetermined amount of paddy is stored in the extension tank 7. Wherein when the extension Momise capacitors 12 is turned on in step S27, the warning is issued by the alarm device 19, housing extension tank 7 in the step S26 is aborted. Furthermore, after the processing in steps S21, 26 and 27 is performed, the control from step S19 is performed.

As described above, the vehicle height automatic switch 17 is turned on to automatically control the vehicle height of the combine regardless of whether the extension tank 7 is extended in any of the automatic and manual control modes. When the combine is being adjusted to a higher vehicle height through the vertical movement device 6 or when the combine is traveling at high speed on the road, etc. The output restricts the extension operation of the extension tank 7 by the output / retraction device 8. In addition, in the automatic mode, the vehicle height automatic switch 17 is turned on, the vehicle height is adjusted to a high value, and the auxiliary gear shift operation is performed. When the speed is high, the extension tank 7 is automatically stored depending on the amount of paddy in the extension tank 7. Is done.

From the above, in the case where the combine is operated for traveling in a wet field, and when the vehicle height of the combine is adjusted to be high by the vertical movement device 6, the output from the advancing / retreating control device 15 is used. The extension of the extension tank 7 is regulated, and the work traveling is performed only in a state in which the extension tank 7 is stored in the grain tank 5, and thus the grain storage in each of the tanks 5 and 7 is performed. Even when the combine is lowered in the center of gravity of the combine and the horizontal control of the left / right traveling device 2 is performed, the left / right balance of the body 1 is maintained well, and the straight traveling during traveling in the wetland is performed. When the vehicle is traveling on the road and the combined vehicle height is adjusted to a high level through the vertical movement device 6, Also, the extension of the extension tank 7 is restricted by the output from the advancing / retreating control device 15, and the road traveling is performed only in a state where the extension tank 7 is housed in the Glen tank 5. Therefore, the extension tank 7 does not block the operator's field of view, and the left-right balance of the machine body 1 is well maintained to prevent a fall accident. Further, even when the extension tank 7 is stored and operated in either the automatic mode or the manual mode, when the amount of paddy in the extension tank 7 detected by the extension paddy sensor 12 is equal to or more than a predetermined value, An output from the advancing / retreating control device 15 controls the storage operation of the extension tank 7 by the output / retraction device 8 and issues an alarm. Therefore, when a predetermined amount of paddy is stored in the extension tank 7, It is also possible to prevent the parts from being damaged due to the storage operation of the extension tank 7.
