DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine for continuously cutting and threshing grain culms and extracting grains from a threshing unit into a grain tank.

[0002]

2. Description of the Related Art Conventionally, a discharge auger for taking out grains from a grain tank is provided, and a revolving member for changing the direction of the outlet of the discharge auger is provided. There was a technology to carry out.

[0003]

In the prior art, since all operations such as stopping and turning of the discharge auger are performed by the driving operation unit, the operator can visually check the tip of the discharge auger from the driver's seat of the combine, or There is a problem in handling operation such that the worker reciprocates between the driver's seat and the tip of the discharge auger, and it is necessary to discharge the grain of the discharge auger and change the discharge position. Therefore, as shown in Japanese Patent Application Laid-Open No. Hei 3-130011, a discharge auger is provided for taking out the grains of the grain tank, a turning member for changing the direction of the discharge auger outlet side is provided, and a driving stop or turning of the discharge auger is performed. There is a technique in which a manual operation unit for performing a manual operation is attached to a distal end of a discharge auger, and the discharge auger is manually operated by both the operation operation unit and the distal end of the discharge auger, thereby eliminating the above-mentioned problem. However, only four push-button switches for individually instructing ascending and descending and turning left and right only during the pushing operation, and the ON operation of the auger only during the pushing operation to store the auger and the set target position. The push button type auto switch that instructs to automatically turn over is provided, so when the auger is supported at a place other than the storage position or the set target position, the auger can be operated only by operating the auto switch. It is not stored automatically, so when the discharge of the grain ends, it is necessary to operate the auto switch to store the auger after performing a turning manual operation to move the auger to the set target position, It is not easy to simplify the auger storage operation with the auto switch, and the auto switch switches the auger until the auger reaches the storage position or the set target position. The need to, there are problems such that not easily performed and improving the auger automatic storage function.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a combine auger in which a discharge auger is provided for taking out grains from a grain tank and a turning member for changing the direction of the discharge auger outlet side is provided. With an automatic storage switch that automatically returns to the storage position with one touch operation, for example, when the work to discharge the grain to the truck bed or container is completed, the discharge auger supported in a place other than the storage position is Since the operation of the automatic storage switch returns to the storage position only, the operation of storing the discharge auger and the storage control structure can be easily performed, and the operation of the automatic storage switch causes the discharge auger to start rotating to the storage position. In this way, it is possible to carry out the operation of traveling to the harvesting place in the next process, and to discharge the auger while moving from the grain discharging place to the harvesting restarting place. Housed obtained, it is capable easily performed and improving the discharge auger automatic storage function.
