Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention comprises an unloader device for sending out grains stored in a grain tank, and a moving actuator for moving a grain outlet by changing the posture of the unloader device.

2. Description of the Related Art As a combine constructed as described above, there is a combine disclosed in Japanese Patent Application Laid-Open No. 3-22916. In this conventional example, sensors for measuring the attitude of an unloader device (an auger in the conventional example) are provided. And an actuator for setting the attitude of the unloader device, and a control device, and the control for automatically operating the unloader device from the storage position to the discharge position by operating the auto switch, and the automatic operation from the discharge position to the storage position. The control operation of the control device is set so as to perform the control to operate the unloader device, and the unloader device is driven by transmitting power to the input pulley of the bottom screw conveyor of the grain tank.

[0003]

However, when the unloader device is switched from the discharge position to the storage position by operating the auto switch, the unloader device operates the auto switch without performing the disengagement operation of the clutch for conveying the grains. In this case, the unloader device turns while the grains are being discharged, which leads to an inconvenience of discharging the grains to a position where they are not collected, and there is room for improvement.

An object of the present invention is to reasonably construct a combine in which grains are not discharged when the discharge port of the unloader device is moved by operating a movement switch.

The clutch control routine (# 300 step) controls the clutch mechanism C only when the clutch switch 38 is turned ON while the storage position switch 43 is OFF, as shown in the flowchart of FIG. If it is determined by the signals from the determination switches 34, 34 that the clutch mechanism C is in the disengaged state, the clutch motor 31 is operated to activate the clutch mechanism C.
When the clutch mechanism C is determined to be in the engaged state, the clutch motor 31 is actuated to disengage the clutch mechanism C. However, the pilot lamp 39 is turned off (# 301 to # 30).
7 steps).

As described above, according to the present invention, by operating the clutch switch 38 to drive the clutch motor 31, it is possible to set the clutch mechanism C to the engaged state and the disengaged state, and to activate the automatic switch 37. Since the posture of the unloader device A can be automatically switched between the storage position E and the discharging position F by the operation, the operator can easily perform the turning operation without trouble, and further, during the discharging of the grain. As described above, when the automatic switch 37 is operated while the clutch mechanism C is in the on state , the control device 44 controls the clutch motor 31 to automatically disengage the clutch mechanism C, so that the unloader device A is stored. The grains are not discharged to a position where they are not collected when turning toward the position. Further, since the clutch mechanism C is not forcibly disengaged when the control stick 36 is operated, the position of the discharge port 11 can be finely adjusted by operating the control stick 36.

[Other Embodiments] In addition to the above-described embodiments, the present invention is, for example, a potentiometer for measuring the swing amount of the horizontal conveyor 10 around the X-axis core, and the horizontal conveyor 10 being operated to be raised to a predetermined height. It is also possible to partly use a limit switch or the like for detecting the above. If such sensors are also used in this way, accurate control becomes possible. Further, in the present invention, the position where the posture of the unloader device A is automatically set by the operation of the automatic switch 37 is set to two positions, but it is also possible to apply it to three or more positions.
