An auger discharge device capable of electrically connecting / disconnecting a paddy discharging drive device to / from the operation unit 136 (see FIGS. 1 and 3) provided at the tip of the lateral auger 19 and / or the operation unit of the cockpit 20. A control program for automatically discharging the paddy after discharging a certain amount of the paddy from the lateral auger 19 in accordance with one operation of the switch 40 can be incorporated.

Thus, how much paddy can be left in the flexible container, or the Glen tank 3
It is now possible to easily determine how much paddy is left in 0, and problems such as loss of paddy due to the delayed timing of the paddy discharge stop operation do not occur, leading to deterioration of paddy quality. Do not do it again, side auger 19
The assistant attached to the tip of the can easily judge these things, and the grain-harvesting work will not be severe.

The discharge of the paddy from the horizontal auger 19 by the auger discharge switch 40 is activated only when the horizontal auger 19 is in a position where the paddy can be discharged. For example, when the horizontal auger 19 is in the storage position of the auger receiver 22, or when the discharge port 19c of the horizontal auger 19 is not facing the ground, or when the discharge port 19c is facing the ground, a receiver such as a flexible container is discharged. The paddy cannot be discharged when it is not arranged below the outlet 19c.

When the horizontal auger 19 is stored in the auger receiver 22, it can be easily determined by operating an auger detection switch (not shown) on the auger receiving surface of the auger receiver 22. In addition, a turning position sensor 44, in which the paddle discharging turning angle of the discharge port 19c of the horizontal auger 19 and the turning angle from the turning reference position of the vertical auger 18 are provided on the horizontal auger 19,
It is possible to determine the paddy dischargeable position by obtaining it in advance and storing this value in the memory. For this reason, when the discharge port 19c of the lateral auger 19 does not face the ground, or when a receptacle such as a flexible container is not arranged below the tip discharge port 19c even if the discharge port 19c faces the ground, the turning is performed. Judging from the angle.

In this way, it is possible to prevent the occurrence of paddy loss due to a malfunction other than when the paddy is discharged, and the lateral auger 1 is provided at a position other than the paddy discharge position.
It is possible to prevent a malfunction of the discharge driving unit when there is 9.

When the paddy discharge amount setting dial 54 is provided on the operation portion 136 at the tip of the horizontal auger 19, the horizontal auger 19 is provided.
By rotating the paddy discharge amount setting dial 54 during the discharge of the paddy, the rotation speed of the engine 100 corresponding to the operation amount of the dial can be set, and the paddy discharge amount from the lateral auger 19 corresponding to the engine rotation speed can be set. it can.

Using the control device 39 shown in FIG.
As shown in, the operation amount of the paddy discharge amount setting dial 54 is divided into, for example, four stages between analog 0V to 5V, and the engine speed corresponding to the analog input value can be set, and the auger discharge switch 40 is turned on. At this time, automatic opening / closing control is performed by adjusting the position of the accelerator 51 so as to achieve the set engine speed. This is shown in the flowchart of FIG.

Therefore, when a predetermined amount of operation is performed from the initial position of the paddy discharge amount setting dial 54, the predetermined number of engine revolutions corresponding to the operated position is used as the driving force, and the paddy corresponding to the power is fed from the lateral auger 19 to the pad. Is discharged. The adjustment of the driving force corresponding to the engine speed is performed, for example, by setting the accelerator opening degree that is linked to the operation control mechanism of the governor of the fuel injection device of the engine 100 to be a predetermined amount. Engine 10 without the governor operation control mechanism
In the case of 0, the paddy discharge amount setting dial 54 is interlocked with the rotation speed control mechanism of each engine 100.
This is shown in the flowchart of FIG.

Conventionally, the amount of paddy discharged from the lateral auger 19 has been changed according to the engine speed, but the engine speed can be controlled by the adjusting mechanism using the paddy discharge amount setting dial.

Although it is possible to adjust the amount of paddy discharged from the lateral auger 19 by the engine speed only with the accelerator lever of the cockpit 20, in the present embodiment, it is provided at the tip of the lateral auger 19. Since the operator can adjust the paddy discharge amount setting dial 54 also from the operation unit 136, the operability of the paddy discharge amount control is further improved.

Further, even when the paddy is discharged from the lateral auger 19 as described above, the paddy discharge amount can be adjusted by operating the paddy discharge amount setting dial 54 without annoying the operator.

When discharging paddy from the horizontal auger 19,
By prioritizing the operation of the accelerator lever of the cockpit 20 over the operation of the paddy discharge amount setting dial 54 described above, the operability during the paddy discharge can be improved.

To this end, as shown in the flow chart of FIG. 8, when the auger discharge switch 40 is operated for the first time after the combine starts to be operated from OFF to ON, the paddy discharge amount setting dial provided at the tip of the horizontal auger 19 is set. Regardless of the operation position of 54, the engine speed is adjusted to an appropriate value by operating the accelerator lever of the cockpit 20. After that, when the auger discharge switch 40 is turned from OFF to ON again (for example, when the paddy is discharged to the second flexible container), the paddy discharge amount setting dial 54 provided at the tip of the horizontal auger 19 is operated to change the dial value. If it changes, control is performed so that the engine speed corresponds to the dial operation position, and the discharge amount can be adjusted by the paddy discharge amount setting dial 54.

In this way, when there is no operator near the tip of the horizontal auger 19, when the paddy is discharged from the horizontal auger 19, the engine rotational speed cannot be adjusted from the operation seat 20 for adjusting the grain yield. The defect disappears.

Further, as shown in the flow chart of FIG. 8, after the set discharge amount by the paddy discharge amount setting dial 54 on the operation portion 136 provided at the tip of the lateral auger 19 is determined, 300 m
If the dial value changes within the specified range within s,
The accelerator opening / closing control is performed to maintain the target value of the engine speed before the dial change. This is to prevent inadvertent movement when the operation position set by the dial 54 changes due to vibration or noise.

Further, the operation portion 13 at the tip of the lateral auger 19
When the paddy discharge amount setting value of the paddy discharge amount setting dial 54 in 6 indicates 5 volts or more, the control of the paddy discharge amount from the lateral auger 19 by the engine speed is stopped, and the accelerator opening / closing control (engine No output for rotation speed control) is performed. This is because when the dial value indicates 5 volts or more, it is determined that the paddy discharge amount setting dial 54 is abnormal and the careless movement is prevented.

When the accelerator lever of the operator's seat 20 is manually operated after detecting the change of the setting dial position of the paddy discharge amount setting dial 54, the engine based on the operating position of the paddy discharge amount setting dial 54 is selected. The control of the amount of paddy discharged from the lateral auger 19 by the rotation speed is stopped.

This is because when the accelerator lever is manually operated, the manual operation is prioritized, and until it is detected that the paddy discharge amount setting dial 54 is operated again and the dial value is newly changed. This is because the accelerator opening / closing control output for controlling the rotation speed is not performed to prevent a problem that the engine rotation speed cannot be adjusted in the operator seat 20 when there is no operator near the tip of the lateral auger 19. .

A vehicle speed higher than a predetermined value (eg 0.2 m /
When the combine is traveling at s or more), the output of the discharge clutch (discharge clutch (ON) 48) while discharging the paddy from the horizontal auger 19 (when the auger discharge switch 40 is ON).
a, the discharge clutch (disengagement) 48b) is operated so that the discharge clutch (disengagement) 48b operates.
Output below 13. At that time, if the discharge clutch 113 is already “off”, the paddy discharge operation is not performed.

Since it is assumed that the combine is running on the road, for example, not in the field when the combine is running at a vehicle speed higher than a predetermined value, the auger discharge switch 40 should not be operated in such a case. This is to prevent the paddy from being scattered on the road or the like when traveling on the road.

In this way, it is possible to prevent a danger due to an erroneous operation of the combine during the operation of discharging the paddy.
