Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a combine equipped with a fir alarm control device .
[0002]
[Prior art]
Conventionally, when a fir alarm control device mounted on a combiner detects that fir has been stored in the Glen tank more than a certain amount by the fir detection means, a notification means such as a buzzer or a warning light is activated, and thereafter for a certain period of time. Alternatively, it is known that the engine is forcibly stopped by cutting a certain distance.
[0003]
[Problems to be solved by the invention]
However, in the above-described conventional fir alarm control device, the operator can manually stop the buzzer. Therefore, if the cutting operation is continued as it is, the engine stops suddenly and the interval from the operation of the notification means to the engine stop is short. However, since it stops at a halfway position in the field, there are problems such as inefficient work.
[0004]
[Means for Solving the Problems]
The present invention was devised for the purpose of solving the above problems, and the fir detection means detects that fir has been stored in the Glen tank more than a certain amount before it is activated and activates the notification means. In the combine equipped with a control device for detecting the cutting distance after detection of the fir detection means, the notification means notifies a different alarm according to the cutting distance after detection of the fir detection means , and the work implement clutch is ON. In the state, when the cutting distance after detection of the fir detection means is a certain distance or more, or the overflow sensor detects fir, the engine is stopped, and further after the engine is stopped to allow the restart of the engine, it is characterized by being configured to stop the engine when the engine has passed a predetermined time after restart

DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is an overall perspective view of a combine to which the present invention is applied. A threshing machine cut and transported by a pretreatment device 1 is threshed and sorted by a threshing device, and fir is stored in a glen tank 2, and the stored fir is discharged into an auger. 3 is discharged outside the machine, and the straw is cut by the cutter device and discharged from the rear. Reference numeral 4 denotes a cabin in which the driver's seat of the combine is installed, and reference numeral 5 denotes a crawler traveling device.
[0006]
The cabin 4 is provided with an openable / closable door 6, and the door close sensor provided on the cabin side for detecting the closed state of the door 6 and the door 6 provided in the glen tank 2 are locked in the open state. The locking device 7 is provided with a door open sensor, and the combine engine can be started only when both the sensors are in the ON state, that is, when the door 6 is locked in the fully closed state or the fully open state. Therefore, it is possible to prevent a problem that the door 6 suddenly opens when the combine engine is started in the half door state and the work is started.
[0007]
FIG. 2 is a right side view of the crawler traveling device 5, in which a crawler 14 is wound between a drive wheel 11, an idler 12, and a roller wheel 13 as usual, and between the core metal projections of the crawler 14. A crawler guide 15 is fixed to the track frame 16 through a long hole so as to be vertically adjustable. Therefore, when the crawler guide 15 is worn by performing harvesting work for a long time and the amount of lap with the cored bar projection is reduced, the conventional crawler guide 15 that cannot be adjusted up and down tends to cause crawler disengagement. In this embodiment, by adjusting the crawler guide 15 in the vertical position, the amount of lap with the cored bar protrusion can be adjusted to the optimum position, and the above problems can be solved.
[0008]
FIG. 3 shows an operation device for the discharge auger 3 built in the cabin 4. Reference numeral 20 denotes an auger manual lever switch for manually turning and raising the discharge auger 3 to an arbitrary position. If it continues, it is controlled to output the auger right turn output continuously after a minute interval after the auger right turn output is outputted, so the tip of the discharge auger 3 is directed right by a minute distance. After a turn, the vehicle stops once, and then turns to the right continuously after an interval of about 1 second. Therefore, when the tip position of the discharge auger 3 is finely adjusted, the auger manual lever switch 20 is operated once to the right turning side to return to the neutral position, so that the discharge auger 3 turns right by a certain minute distance. Thus, anyone can easily adjust the tip end position of the discharge auger 3 to the target position without a delicate switch operation as in the prior art.
[0009]
Reference numeral 21 denotes an automatic storage switch for automatically turning the discharge auger 3 from the discharge position to the storage position. Reference numeral 22 denotes an automatic turn switch for automatically turning the discharge auger 3 to the discharge position set by the turning position setting dial 23. The discharge auger 3 during automatic turning or automatic storage can be stopped by operating. 25 is a grain discharge switch for discharging fir in the Glen tank out of the machine.
[0010]
FIG. 4 is a block diagram of the control device of the present invention. On the input side of the CPU 30, the auger manual lever switch 20, automatic storage switch 21, automatic turning switch 22, turning position setting dial 23, emergency stop switch 24, grain In addition to the discharge switch 25, a work machine clutch switch 31 for detecting ON / OFF of the work machine clutch and a fir sensor 32 (fir detection means) for detecting that a certain amount of fir is stored in the Glen tank 2 are connected. Yes. Also, on the output side, an auger turning motor 35 for turning the discharge auger 3, an auger lifting cylinder 36 for raising and lowering the discharge auger 3, a horn (notification means) 37 for notifying the operator of the amount of fir storage by sound, and the amount of fir storage Is connected to a fir alarm lamp (notification means) 38 for notifying the operator of the engine and an engine stop solenoid 39 for stopping the engine in an emergency.
[0011]
FIG. 5 is a flowchart of a fir alarm control device which is a main part of the present invention. First, in S1, the state of the work implement clutch switch 31 is determined. If it is determined to be "ON", the process proceeds to S2 and is determined to be "OFF". Then move on to the next control.
[0012]
In S2, the current state of the fir sensor 32 is determined. If it is determined to be “ON”, the process proceeds to S3. If it is determined to be “OFF”, the fir alarm flag and the restart timer are reset, and the next control is performed.
[0013]
In S3, the previous state of the fir sensor 32 is determined. If it is determined to be “ON”, the process proceeds to S4. If it is determined to be “OFF”, a single sound is output to the horn, 1 is set in the fir alarm flag, and the process proceeds to S5.
[0014]
In S4, the state of the fir alarm flag is determined. If it is determined that "≠ 0", the process proceeds to S5. If it is determined that "= 0", the fir alarm lamp is turned on, the restart timer is set, and the process proceeds to S6.
[0015]
In S5, the state of the cutting distance x after the fir sensor is turned on is determined. If “x ≧ A” is determined, the process proceeds to S7. If “x <A” is determined, the fir alarm lamp 38 is lit and output for the next control. Move on.
[0016]
In S6, it is determined whether the restart timer has expired, and if "YES" is determined, the engine stop is output to the engine stop solenoid 39 to proceed to the next control, and if "NO" is determined, the next control is performed.
[0017]
In S7, the state of the cutting distance x after the fir sensor is turned on is determined. If “x ≧ B” is determined, the process proceeds to S8. If “A ≦ x <B” is determined, the fir alarm lamp 38 is set to the A pattern with a wide interval. Blinks and outputs to S9.
[0018]
In S8, the state of the cutting distance x after the fir sensor is turned on is determined. If “x ≧ C” is determined, the fir alarm lamp 38 is lit and output, a continuous sound is output to the horn 37, and the engine stop solenoid 39 is output to stop the engine. Then, the process proceeds to the next control, and if “B ≦ x <C” is determined, the fir alarm lamp 38 is blinked and output in a B pattern with a narrow interval, and the process proceeds to S10. Note that A, B, and C are set values and have a relationship of A <B <C.
[0019]
In S9, the state of the fir alarm flag is determined. If it is determined that "≠ 2", a single sound is output to the horn 37, 2 is entered in the fir alarm flag, and the next control is performed. If "= 2" is determined, the next control is performed. Move on.
[0020]
In S10, the state of the fir alarm flag is determined. If it is determined that "≠ 3", a single sound is output to the horn 37, 3 is entered in the fir alarm flag, and the next control is performed. If "= 3" is determined, the next control is performed. Move on.
[0021]
Therefore, when harvesting work is performed with a work implement clutch and a combine harvester, the horn 37 sounds a single tone before the glen tank 2 is full (to the extent that it is possible to cut more than one way in the field after alarming), and a fir alarm lamp 38 lights up.
[0022]
Thereafter, when the cutting operation is continued for a certain distance A or more, the horn 37 sounds a single sound again and the fir alarm lamp 38 blinks at a constant cycle A with a long interval.
[0023]
After that, when the cutting operation is continued and the distance becomes equal to or longer than the predetermined distance B, the horn 37 sounds again and the fir alarm lamp 38 blinks at a fixed period B shorter than the period A.
[0024]
Further, when the cutting operation is continued after that and the distance C exceeds a certain distance C, the horn 37 sounds continuously and the fir alarm lamp 38 is lit and the engine is stopped.
[0025]
Therefore, even after the first fir alarm, the fir alarm lamp 38 sequentially notifies different alarms according to the harvesting distance of the combine, so that the operator can grasp how much distance can be harvested later, and the harvesting work can be performed in the middle of the field. The work can be performed efficiently without causing problems such as being impossible.
[0026]
Also, when the engine is restarted after the engine is stopped, even if the engine stops in the middle of the field, the engine is left in the preprocessing device 1 for a certain period of time with the work implement clutch being turned on by the restart timer. The time until the cereal is processed by the cutter device via the threshing device) can be started, so that the cereal remaining in the pretreatment device 1 can be processed without dropping.
[0027]
In this embodiment, the final determination of the engine stop output is made based on the cutting distance x. However, an overflow sensor is provided, and the engine stop output is determined based on the detection of the overflow sensor. Alternatively, the alarm level may be further increased or decreased from the current two levels.
[0028]
【The invention's effect】
As described above, according to the present invention, the fir detection means detects that the fir has been stored in the Glen tank more than a certain amount before it is full, operates the notification means, and sets the cutting distance after the fir detection means is detected. In a combine equipped with a control device to detect, the alarm means notifies different alarms according to the cutting distance after detection of the fir detection means, and the cutting distance after detection of the fir detection means when the work implement clutch is ON. It is configured to stop the engine when the distance is longer than a certain distance or the overflow sensor detects fir. Further, after the engine stops, the engine can be restarted. since it is configured to stop the engine when a predetermined time elapses after the operator can understand what can reaper distances much after It can work efficiently without causing problems such can not work cutting in the field of middle. In addition, even if the engine stops in the middle of the field, the engine can be driven for a certain period of time with the work implement clutch turned on, so that the cereal remaining in the pretreatment device can be processed without dropping. .
