Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a grain discharging device for a grain harvester such as a combine or a harvester. Conventionally, a grain discharge device of a combine as a grain harvester is provided with a discharge auger via a discharge relay section at the top of a vertical discharge auger erected at the rear of a Glen tank. The discharge auger is changed from the storage position to the grain discharge position by the lifting mechanism and the swivel mechanism, and is directed to the bed of a truck waiting on the road or a grain storage tank (hereinafter referred to as a bed) installed on the bed. After positioning, the grain discharge clutch is then "on" actuated to accommodate the grains in the Glen tank on the carrier. Further, the conventional grain discharging device detects the turning position of the discharging auger by a potentiometer and, when the discharging auger is in the retracted position, turns on a grain discharging switch of a grain discharging clutch. The control is made so as to make it impossible to prevent the grains from being discharged from the discharge auger in the storage position due to an erroneous operation. [0004] As described above, the conventional grain discharging device can prevent a grain discharging trouble due to an erroneous operation of the grain discharging switch when the discharging auger is in the retracted posture. However, if the grain discharge switch is turned “ON” due to an erroneous operation during raising / lowering or turning of the discharge auger,
There is a problem that the grain discharging clutch operates to discharge the grain. Further, in the conventional grain discharging device, after the discharging auger is positioned on the loading bed, the discharging auger is continuously discharged from the grain discharging port while rotating the discharging auger, so that the grains are uniformly distributed in the loading bed. There is a problem that the operation of discharging is complicated and inefficient. In order to solve the above problem, the present invention prevents a grain discharge trouble due to an erroneous operation of a grain discharge switch while the grain discharge is stopped, while allowing the discharge auger to rotate during the grain discharge. It is an object of the present invention to provide a grain discharging device of a grain harvesting machine that can be turned into a grain. [0007] In order to achieve the above object, a grain discharging device of a grain harvester according to the present invention is provided with a vertical discharge vertically set in a Glen tank 3 containing grains. Auger 40
And a discharge auger device 4 connected to the vertical discharge auger 40 and capable of being switched between a storage position and a particle discharge position by the elevating / lowering rotating mechanism 9. In the grain discharge device of the grain harvester that discharges or stops the grain in the Glen tank 3 by the “on” or “off” operation of the clutch 5, the discharge auger 43 during the stop of the grain discharge is turned up and down and turned. When the grain discharge clutch 5 is operated to “enter” when the grain is discharged, the discharge auger 43 is lifted and lowered and the discharge of the grain is stopped, and the discharge auger 43 during the discharge of the grain is raised and lowered and turned. Is configured so that the discharge auger 43 can be turned up and down while the grains are discharged. Embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 1, a combine 1 as a grain harvester is provided on one side of a traveling body 1b having an endless belt type traveling device 1a (back side in the figure), similarly to a conventional combine.

As described above, according to the present invention, the vertical discharge auger 40 erected on the Glen tank 3 for accommodating the grains, the vertical discharge auger 40 connected to the vertical discharge auger 40, and a vertically rotating mechanism 9 is provided with a grain discharge auger device 4 comprising a discharge auger 43 that can be switched between a storage position and a grain discharge position, and furthermore, the grain discharge clutch 5 is turned on or off by turning the grain discharge clutch 5 into the Glen tank 3. In the grain discharging device of the grain harvester that discharges or stops the grain, the grain discharging clutch 5 is turned on while the discharging auger 43 during the grain discharging is being turned up and down. In this case, while the raising and lowering of the discharge auger 43 and the discharge of the grain are stopped, when the discharging auger 43 during the discharge of the grain is operated to raise and lower, the raising and lowering of the discharge auger 43 in a state where the kernel is discharged is performed. To allow turning With this configuration, even when the grain discharge switch 70 is turned on by mistake when the discharge auger 43 during the grain discharge is stopped is moved up or down or turned, the discharge clutch 5 does not "on". In addition, it is possible to prevent grain discharge due to an erroneous operation. Therefore, when the grain discharge is stopped, the discharge auger 43 can be switched from the grain discharge posture to the storage posture, or from the storage posture to the kernel discharge posture, without any trouble. If the auger manual lever 7 is erroneously operated during the grain discharging operation of discharging the grains from the discharging auger 43, the turning of the discharging auger 43 is continued.
The grains can be evenly and efficiently stored in the luggage carrier such that the storage heights of the grains are substantially equal.
