Description

[Detailed description of the invention] The present invention provides an agricultural machine such as a combine harvester or a rice transplanter.
The actuating parts of two clutches, etc. can be operated simultaneously or only one actuating part can be operated remotely by one operation. An example of this is explained with reference to a drawing. In the figure, 1 indicates the operation of an operating column, etc. A shaft 2 supported on the operation table 1 has an operation piece 3 in the center and levers 4 on both sides thereof.
. The protrusions 7 and 8 are provided to protrude inwardly, and inward protrusions 9 and 10 are provided at the tips, respectively, so that the operating handle shaft 6 is connected to the protrusions 7 and 8.
A wire 11 is connected to one lever 4 via a link 13 with a spring 12 and one end of which is connected to an actuating part such as a clutch (not shown) in a combine harvester. The other lever 5 is connected to a link 16 with a spring 15 connected to a wire 14 whose one end is connected to an operating part such as another clutch (not shown) in the combine.
The operating handle shaft 6 has two retaining pieces 17. 18 protrudes in the right angle direction, and the operating handle shaft 6
When rotated in the direction of the solid line arrow A, one engaging piece 17 comes into contact with the inward protrusion 9 on one of the levers 4, and when the operating handle shaft 6 is rotated in the direction of the dotted line arrow, the other retaining piece 18 In other words, the handle shaft is configured to selectively engage with one of the levers by rotating the operating handle shaft 6 so as to come into contact with the inward protrusion 10 on the other lever 5. It is.

In this structure, when the operating handle shaft 6 is rotated about the shaft 2 in the direction of arrow A from the position shown by the solid line in FIG. Both levers 4, 5 are brought into contact with both protrusions 7, 8 in 5 at the same time.
are rotated simultaneously in the direction of arrow A, so both clutches connected to both levers 4 and 5 via wires 11 and 14 are turned ON or OFF at the same time, and the operating handle 6 is turned in the direction of arrow A at the position indicated by the two-dot chain line. If it rotates, one of the retaining pieces 1
7 abuts and secures with the inward protrusion 9 on one lever 4, and the other retaining piece 18 comes off from the inward protrusion 10 on the other lever 5, so the operating handle shaft 6 is moved along the dotted arrow B
By rotating the lever 4 about the shaft in the direction shown by the solid line in FIG.
It can be operated as FF or ON, and in the state shown by the two-dot chain line in Fig. 2,
When the operating handle shaft 6 is rotated in the direction of the dotted arrow, one engagement piece 17 comes off from one lever 4, while the other engagement piece 18 comes into contact with the inward protrusion 10 on the other lever 5. Therefore, by rotating the operating handle shaft 6 in the direction of the dotted arrow B, the wire 14 is attached to the other lever 5.
It is possible to turn off or turn on only the other clutch that is connected via the handlebar, and by operating the single operating handle shaft 6, the two clutches can be turned on or off at the same time.
Alternatively, only one clutch can be turned OFF or ON.

In this case, the actuating part may not be a clutch but another actuating part such as a brake, and one actuating part can be used as a clutch and the other as a brake, and when one actuating part is turned on, the other actuating part is turned off. It can also be applied to cases where the two actuators operate in opposite directions.

It is also possible to use a single retaining piece on the operating handle shaft so that the operating handle shaft is rotated about 180 degrees about its axis and engaged with one of the levers 4, 5.

Therefore, according to the present invention, in an agricultural machine such as a combine harvester, two actuating parts such as clutches can be operated simultaneously or independently, compared to the conventional method in which the two actuating parts are operated by separate operating levers. The structure is simplified and the operation is simplified, improving the operability of the agricultural machine, and the two actuating parts can be operated simultaneously in an emergency, thereby improving safety.
