Description

[Detailed Description of the Invention] The present invention is characterized in that the stem culm locking claw is held at the base of the endless rotation band, and the rotation axis of the ring body around which the endless rotation band is wound. A stem culm locking member is pivotally connected in a state in which it can be raised and lowered around an axis substantially parallel to the stem culm, and the stem culm locking claw is configured to be retracted downward in the direction of movement and into the case at the conveyance terminal end. Regarding the conveyance device, it is possible to easily avoid drawing of the stem culm into the case by the locking claw when the stem culm locking claw is laid down and retired into the case, and furthermore, the locking action of the locking claw when transporting the stem culm is provided. The purpose is to prevent any deterioration.

Next, embodiments of the present invention will be described based on illustrative drawings.

An endless rotating chain in which a pair of upper and lower sprockets 2 and 3 are mounted rotatably around mutually parallel axes in a lifting case 1, and a plurality of stem culm locking claws 4 are attached at regular intervals. 5 is wound around both the sprockets 2 and 3 to constitute a stem culm pulling device that is installed in a combine harvester or a binder.

To attach each of the locking claws 4 to the chain 5, as shown in FIGS. member 7,
7, the sprockets 2 and 3 are pivoted and connected in a freely undulating manner by a pin 8 having an axis substantially parallel to the rotation axes of the sprockets 2 and 3, in a state where the mounting strength can be increased by hugging them from both outside sides. It is.

A member 9 is brought into contact with the locking pawl 4 at the terminal end on the descending side of the chain 5 in order to make it stand up, and a member 9 is attached to the locking pawl 4 near the terminal end on the ascending side of the chain 5. On the other hand, rails 10 that are brought into contact with the lifting case 1 to keep it upright are respectively installed upright on the lifting case 1, so that as the chain 5 is rotationally driven,
Each of the locking claws 4 stands up at the lower end of the case, raises itself in that position and moves upward on the path side, and at the end of the action,
Due to its own weight and resistance from the stem culm, it is forced to retire downward in the direction of movement and into the case.

As shown in FIGS. 2 and 5, each of the locking claws 4 is configured such that the forming portion 4b of the locking surface 4a for the stem culm is bent. The recessed part 11 into which the chain winding part of the upper sprocket 2 is inserted when the upper sprocket 2 is folded down and retired is projected forward in the pawl movement direction from the straight line connecting the base P1 and the tip P2 of the working surface 4a. It is formed on the back side of the working surface forming part 4b, and the receding angle θ of the locking working surface 4a with respect to the case 1 when retiring into the case prevents the formation of an inclined part at the tip of the locking working surface. Both should be made as large as possible.

Incidentally, the above-mentioned locking claw configuration can also be applied to a locking conveyance device.

Further, the endless rotation chain 5 can be changed to a belt or the like, and these are collectively referred to as an endless rotation belt 5, and the sprocket 2 is referred to as a wheel body 2.

In summary, the present invention provides the above-mentioned stem culm locking and conveying device with a hook attached to the back side of the stem culm locking claw 4 by a straight line connecting the base end P1 and the tip P2 of the working surface 4a of the claw 4. It is characterized in that a recessed portion 11 into which the wheel body 2 is inserted is formed in a state of protruding forward in the direction of movement.

That is, according to the above-mentioned locking pawl configuration, as shown in FIG. Since the receding angle θ1 is larger than that of the conventional locking claw 12 which is not equipped with the locking claw 11, the stem culm is less likely to be drawn into the case by the falling and retiring locking claw 4 than before.

On the other hand, as shown in the figure, there is a portion 12 on the distal end side of the locking surface of the locking claw 12 of the conventional structure that slopes downward in the claw movement direction.
It is conceivable to increase the receding angle θ1 by forming an angle a, but in this case, the stem culm located on the tip side of the locking claw 12 tends to slip and come off from the locking claw 12 when the stem culm is transported. Become.

However, according to the configuration of the present invention, the locking surface 4
Since it is not necessary to form the sloped portion as described in (a), the stem culm does not come off during transportation.

In short, according to the present invention, while the stem culm is transported reliably in the same way as in the past, it is easier to avoid drive troubles associated with the retraction of the stem culm into the case.
