  FIG. 6 is a flowchart showing the alarm control of the present invention, and will be described below based on this flowchart.

  First, in step S1, it is determined whether or not the temperature of the engine coolant by the water temperature sensor 42 is equal to or higher than a set value. If it is equal to or higher than the set value, the process proceeds to step S2, and if it is equal to or lower than the set value, the process proceeds to step S3. .

  In step S2, the direction indicator 24R near the water temperature sensor 42 installed in the circulation path of the engine cooling water and the water temperature lamp 52 of the meter panel 17 are turned on, and a warning sound (intermittent sound) from the horn 57 is turned on. The process proceeds to step S3.

  In step S3, it is determined whether or not the work implement clutch is ON / OFF, that is, whether or not the work implement clutch switch 51 is ON and the cutting operation is in progress. If the cutting operation is not in progress, the process returns to step S1.

  In step S4, it is determined whether any of the above-described plurality of clogging sensors 43, 45, 46, 47 is turned on and clogging of cereals or waste has occurred. If the sensor is turned on and clogging of cereal or waste has occurred, the process proceeds to step S5, and if clogging has not occurred in the OFF state, the process proceeds to step S15.

  In step S5, it is determined whether or not the pretreatment clogging sensor 43 that detects clogging of the cereal mash in the handling depth conveying device of the preprocessing unit 6 is turned on to cause clogging. If clogging has occurred, the process proceeds to step S6, and if no clogging has occurred in the OFF state, the process proceeds to step S7.

  In step S6, the direction indicator 24L on the left front side of the machine body and the preprocessing lamp 54 of the meter panel 17 at positions close to the handling depth conveying device where the preprocessing clogging sensor 43 is installed are turned on, and the process proceeds to step S13. .

  In step S8, it is determined whether or not the feed chain clogging sensor 45 that detects clogging of the waste in the feed chain of the threshing unit 7 is turned on to cause clogging, and clogging has occurred in the ON state. If so, the process proceeds to step S9, and if clogging has not occurred in the OFF state, the process proceeds to step S10.

  In step S9, the direction indicator 24L 'on the front left side of the machine body at a position close to the feed chain where the feed chain clogging sensor 45 is installed is turned on, and the process proceeds to step S13.

  On the other hand, in step S10, it is determined whether or not the clogging sensor 46 for detecting the clogging of the waste in the waste chain of the waste transporting device is turned on to cause clogging. If it has occurred, the process proceeds to step S11, and if no clogging has occurred in the OFF state, the process proceeds to step S12.

  In step S11, the direction indicator 25L on the left rear side of the machine body at a position close to the waste transporting device where the waste clogging sensor 46 is installed is turned on, and the process proceeds to step S13. Further, in step S12, the direction indicator 25R on the right rear side of the machine body at a position close to the post-processing unit 8 where the cutter clogging sensor 47 is installed is turned on, and the process proceeds to step S13.

  In step S13, it is determined whether any one of the plurality of clogging sensors 43, 45, 46, 47 described above has changed from the OFF state to the ON state, and any of the sensors has changed from the OFF state to the ON state. If it has become, it will progress to step S14, and if it is an ON state from before, it will progress to step S15.

  In step S14, a warning sound from the horn 57 is output as a single sound, and the engine stop solenoid valve 53 is turned ON to stop the engine by fuel cut, and the process proceeds to step S15.

  In step S15, it is determined whether or not the overflow sensor 48 for detecting the full state of the straw in the grain tank 9 is turned on. If the straw is full in the grain tank 9 in the ON state, the process proceeds to step S16. If it is not full in the OFF state, the process returns to step S1.

  In step S16, the direction indicator 24R 'on the front right side of the fuselage at a position close to the grain tank 9 where the overflow sensor 48 is installed and the full lamp 56 of the meter panel 17 are turned on, and the process proceeds to step S17.

  In step S17, it is determined whether or not the overflow sensor 48 has changed from the OFF state to the ON state. If the overflow sensor 48 has changed from the OFF state to the ON state, the process proceeds to step S18.

  In step S18, a warning sound from the horn 57 is output as a single sound, and is output to the engine stop solenoid valve 53 to stop the engine by fuel cut, and the process returns to step S1.

  That is, the above-described alarm control of the present invention is performed by any one of the plurality of abnormality detection means 42, 43, 45, 46, 47, 48 provided in each part of the machine. When an abnormality is detected, an indicator group 33, which is a corresponding abnormality display means of the meter panel 17 provided in the control unit 23, for example, a water temperature lamp 52, a pretreatment lamp 54, a dredge treatment lamp 55, a dredge full lamp 56, etc. are turned on. The direction indicators 24L, 24L ′, 24R, 24R ′, 25L, and 25R that are close to the abnormality detecting means 42, 43, 45, 46, 47, and 48 that detected the abnormality are turned on or In addition to blinking, a warning sound from the horn 57 is output intermittently or as a single sound to inform the operator and auxiliary workers.

  More specifically, when the water temperature sensor 42 detects an abnormality in the engine cooling water, the direction indicator 24R located near the circulation path of the engine cooling water in which the water temperature sensor 42 is installed is turned on or blinked, and the pretreatment is clogged. When the sensor 43 detects clogging of the cereal, the direction indicator 24L on the front left side of the fuselage at a position close to the handling depth conveying device where the preprocessing clogging sensor 43 is installed is turned on or blinked to clog the feed chain. When the sensor 45 detects the clogging of the exhaust chain, the direction indicator 24L ′ on the left front side of the fuselage at a position close to the feed chain where the feed chain clogging sensor 45 is installed is turned on or blinked. When the waste clogging is detected, the direction indicator 25L on the left rear side of the machine body at a position close to the waste chain of the waste transporting device in which the waste clogging sensor 46 is installed. When the cutter clogging sensor 47 detects clogging of the waste, the direction indicator 25R on the right rear side of the fuselage at a position close to the post-processing unit 8 where the cutter clogging sensor 47 is installed is lit or blinked. When the overflow sensor 48 detects a full state of straw in the grain tank 9, the direction indicator 24R 'on the front right side of the fuselage located near the grain tank 9 where the overflow sensor 48 is installed is turned on. Or it is supposed to blink. Therefore, the auxiliary worker who works together with the operator who is on the combine 1 can easily grasp the position of the trouble that has occurred in the machine body from the position away from the combine 1. This makes it possible to respond quickly and improve workability. In addition, when detecting each clogging sensor 43, 45, 46, 47 and the overflow sensor 48, since the engine is stopped simultaneously, a single sound output is made in consideration of noise around the field. On the other hand, when the overheating of the water temperature sensor 42 is detected, it is better not to stop the engine as a countermeasure against overheating.

  By the way, in recent years, operators who are on the combine 1 often use the mobile phone to communicate with each other. However, since the ringtone is drowned out by the noise during work, it is difficult to hear the combine. A mobile phone is connected to a microcomputer constituting the control unit 41 via a serial communication interface, a controller, and a coupler (not shown), and an indicator on the meter panel 17 and a direction indicator are linked to the incoming call of the mobile phone. 24L, 24L ′, 24R, 24R ′, 25L, and 25R may be configured to be capable of blinking or lighting control so that an operator or a peripheral worker can quickly see the incoming call of the mobile phone.
