Regarding.

[Conventional technology]

Since the agricultural binder conveyance device configured as described above rotates the horizontal conveyance device within a plane orthogonal to the reaped stem culm, the locking conveyance protrusion attached to the horizontal conveyance device is rotated perpendicularly to the reaped stem culm. Engage in posture,
This has the advantage of being able to reliably carry out locked conveyance by the conveyor.

By swinging the auxiliary transport device backward, the amount of protrusion of the auxiliary transport device to the outside of the aircraft body can be minimized, and even if the auxiliary transport device is swung backward in this way, By this,
Since the desired stem culm conveyance can be carried out without clogging the conveyance path of the conveyance device, the auxiliary conveyance device can be swung backwards during splitting work, and the planted stem culm can be transported with the auxiliary conveyance device. It is possible to release the bundled stem culm without causing the troubles that occur when it is caught or pushed down. Moreover, because the pivot axis of the auxiliary conveyance device is located in a backward tilted position along the inclination direction of the guide plate, the auxiliary conveyance device is Although the terminal end side is lowered, by swinging the auxiliary transport device upward, the auxiliary transport device can be positioned above the propulsion wheels, so the auxiliary transport device can be moved to the side of the aircraft without being obstructed by the propulsion wheels. It can be stored within the width. Furthermore, since the clutch is automatically disengaged by swinging the auxiliary conveyance device upward, there is an advantage that the auxiliary conveyance device will not be activated unexpectedly when the auxiliary conveyance device is stored. .

In the agricultural binder conveying device having the above-mentioned advantages, power is transmitted from the horizontal conveying device to the auxiliary conveying device between the end face of the winding wheel on the terminal end side of the horizontal conveying device and the end face of the winding wheel on the starting end side of the auxiliary conveying device. , respectively, by means of engaging claws provided in a state protruding in the axial direction, and the abutment surfaces of the engaging claws provided in each ring body in a state protruding in the axial direction are as follows: It was formed parallel to the axis.

[Problem that the invention attempts to solve]

Maintaining the occlusion of the interlocking claws relies on a coil spring that restricts the swinging of the auxiliary transport device around the horizontal axis, so the biasing force of the spring must be strong. The drawback was that it was difficult to change the posture around the horizontal axis.

Therefore, as a means to eliminate the above-mentioned drawbacks, in order to maintain the relative posture of the auxiliary transport device with respect to the lateral transport device, brackets are extended from the frame of the lateral transport device 11 and the frame of the auxiliary transport device, respectively, and the brackets are connected to each other. Although it is conceivable to provide a locking device such as connecting bolts, such a case has the disadvantage of requiring a separate locking device.

The object of the present invention is to easily change the posture of the auxiliary conveyance device without providing a separate locking device by devising the structure of the interlocking claw.

[Means for solving problems]

The technical means of the present invention taken to achieve the above object is to form the abutment surfaces of the two engaging claws into inclined surfaces that prevent relative movement of the two engaging claws in the axial direction due to the transmission of engagement. It was formed.

[Effect]

Due to the biting transmission of the interlocking claws, a component force that attracts both the interlocking claws toward each other in the axial direction acts, so it is possible to prevent the relative separation of the interlocking claws in the axial direction. The biasing force of the spring that restricts the swinging of the device around the horizontal axis can be weakened.

[Effect of idea]

Therefore, by using a simple structure in which the contact surface of the engaging claw is formed into an inclined surface, it is possible to attach a spring to restrict the swinging of the auxiliary conveyance device around the horizontal axis without using a separate locking device. The force can be weakened, and the attitude of the auxiliary conveyance device can be easily changed.
