JP 2011-019480 A (paragraph number [0041], FIGS. 1 and 2)

According to the operation device of the grain discharge auger in the conventional combine described above, since the discharge clutch lever and the command switch are arranged adjacent to one operation panel on the same plane, the discharge clutch lever When in the upright state, the operation part of the discharge clutch lever is separated from the operation part of the command switch, so that the respective operations do not interfere with each other.
However, when the discharge clutch lever is swung and is in a tilted state, the operation part of the discharge clutch lever is lowered to a position close to the operation panel. There is a risk of interference.
Accordingly, the discharge clutch lever and the command switch are difficult to operate, and improvement in operability has been desired.

  Accordingly, an object of the present invention is to provide an operation device for a grain discharging auger in a combine which can solve the above-mentioned problems and improve operability.

A first characteristic configuration of the present invention is a manually operated command switch for commanding turning and raising / lowering of a grain discharging auger provided in a traveling machine body, a grain discharging state and a grain of the grain discharging auger. An operating device for a grain discharging auger in a combine provided in an operating panel disposed at a position on a side of a driver seat, with a swinging type discharging clutch lever for switching between a stopped state, the operating panel comprising: a first operation panel, Yes constitutes a second operating panel portion formed at its forward one step lower, wherein the first operation panel, on the side of the range closer to the driver's seat, the A protruding wall portion with a front end protruding forward so as to be adjacent to the driver seat side of the second operation panel portion is provided, and the discharge clutch lever swings back and forth from above to the front of the protruding wall portion. Before you can move Yes disposed in the first operation panel, the command switch is of the upper surface of the second operation panel is in place are arranged on the lateral side portions of the projecting wall portion.

According to the first characteristic configuration of the present invention, since the discharge clutch lever is arranged in the first operation panel portion that is one step higher than the second operation panel portion, even when the discharge clutch lever is in the collapsed state, it is one step lower. It is possible to ensure a distance from the command switch arranged in the second operation panel portion.
Therefore, the swing operation of the discharge clutch lever can be performed without worrying about the presence of the command switch, and the operability can be improved.
Similarly, the operation of the command switch can be operated freely and efficiently without being restricted by the operation because the operation area of the discharge clutch lever does not interfere.
Further, since the discharge clutch lever is configured to be swingable in the front-rear direction, even when operated from the driver's seat, the unnatural posture is unlikely to be operated efficiently.
As a result, the discharge clutch lever and the command switch can be operated freely and efficiently, and the operability can be improved.
In the second characteristic configuration of the present invention, the protruding wall portion is disposed closer to the driver seat than the second operation panel portion, and a portion adjacent to the front of the protruding wall portion is the second It is located below the upper surface of the operation panel.
According to a third characteristic configuration of the present invention, in the first operation panel portion, a scouring process switching lever of a threshing apparatus is arranged to be swingable back and forth in a state of being spaced apart from a side of the discharge clutch lever. The command switch is arranged so as to be positioned on the side of the exclusion processing switching lever in a state of reaching the swinging lower end portion in a plan view, and the exclusion processing switching lever is The operation part is formed so as to be positioned in front of the front end part of the second operation panel part in a state of reaching the moving lower end part, and the operation part in the state of reaching the swinging lower end part is formed. On the lower side, a panel part lower than the upper surface of the second operation panel part is provided.
According to a fourth characteristic configuration of the present invention, the protruding wall portion and the second operation panel portion are formed such that their front end portions are continuous in a plan view.

Further, the instruction switch may I tare disposed at a position does not swing trajectory planarly interfere in the discharge clutch lever.

According to that configuration, the swing trajectory of the discharge clutch lever, do not interfere commanded switch in a plan view, the operation unit to each other with the discharge clutch lever and the command switch, not longitudinally only, spaced in the transverse direction In addition, the operability can be improved more reliably.

Further, the instruction switch may it arranged on the side of the discharge clutch lever enters operation being tilted to swing the lower end tare.

According to the configuration, in addition to the command switch and the discharge clutch lever does not interfere, when the operation state enters Tilt the discharge clutch lever, because the command switch is positioned on the side, of the mutual The operation can be performed without greatly moving the hand, and the operability can be further improved.

In addition, the first operation panel unit is arranged side by side with the evacuation processing switching levers of the threshing device, with an interval on the side of the discharge clutch lever.
Wherein the said command switches are provided in the second operation panel, the Hai稈processing may we swing trajectory and planarly interfering not disposed at a position tare of the switching lever.

According to that configuration, the swing trajectory of Hai稈processing switching lever, do not interfere commanded switch planarly, the operation unit to each other between the command switch and Hai稈processing switching lever is not vertical direction only, horizontal It is also possible to improve the operability more reliably by separating from the direction.

Further, the instruction switch may it arranged on the side of the Hai稈processing switching lever in the state reached swinging lower end tare.

According to the configuration, in addition to the command switch and Hai稈processing switching lever does not interfere, when the operation state defeating Hai稈processing switching lever, because the command switch is located on the side The mutual operations can be performed without moving the hand greatly, and the operability can be further improved.

According to a fifth characteristic configuration of the present invention, the operation portion of the command switch is positioned below the first operation panel portion.

According to the fifth characteristic configuration of the present invention, even if the lever (the discharge clutch lever or the evacuation process switching lever) installed on the first operation panel unit is swung to a posture in which the lever is tilted to the side, Since the operation part of the command switch is located on the lower side, the respective operation ranges do not overlap and are easy to operate. Therefore, the operability can be improved more reliably.

According to a sixth characteristic configuration of the present invention, there is provided a cleaner installation portion in which an air cleaner is installed behind the operation seat and beside the operation panel, and an upper end operation portion of the discharge clutch lever is located at a position closest to the cleaner installation portion. It is located above the top.

According to the sixth characteristic configuration of the present invention, even if the discharge clutch lever is arranged close to the cleaner installation part, the upper end operation part of the discharge clutch lever is installed above the uppermost part of the cleaner installation part. Therefore, when operating by grasping the upper end operation section, the cleaner installation section does not get in the way, and the lever operation can be performed smoothly.
