Description

[Detailed description of the invention] The present invention has a forced pulling device configured to horizontally rotate the stem culm locking claw at the starting end side of the pulling device. In order to guide the stem culms that are not to be harvested to the sides of the machine, the stem culm locking pawl is rotated vertically upward on the starting end side and then moved from the front lower part of the machine towards the rear upper part of the machine. This invention relates to a reaper equipped with a weed culling device.

This type of reaper forcibly raises even if the stem culm has fallen down on the side of the target stem culm, ensuring that the non-reapable stem culm can be separated, and the non-reapable stem culm becomes the target stem culm. This prevents the stem culm that is not to be harvested from being pulled out and the tip of the stalk from being squeezed and shed as a result of the pulling action.

However, in general, conventionally, the locking claw of the weeding device is rotated vertically in a vertical trajectory at its starting end side, and as shown in FIG. ...

Neither of the above works, and the grass is neither cut nor pulled up, resulting in the problem of uncut grass.

In view of the above-mentioned points, the present invention aims to avoid the generation of dead space between the movement paths of the above-mentioned side locking claws and prevent the stem culm from being left uncut by simple modification. purpose.

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

A pulling device 1 that pulls up planted stem culms in the field, a reaping device 2 that reaps the lifted stem culms, and a feed chain 3 that changes the posture to a nearly horizontal position while conveying the cut stem culms to the rear upper part of the machine body. A reaping section 6 is configured in which conveying devices 4 are successively connected to the combine harvester, and the harvesting section 6 reaps the planted stalks and culms in the field and supplies them to the threshing device 5.

Stem culm introduction route R to the reaping device 2 by the pulling device 1
A forced weeding device 8 is provided, which is located at each side in the direction of movement of the aircraft, and whose front end is located forward of the aircraft from the front end of the pulling device 1. It rotates around the horizontal axis so that it protrudes only in the upward movement state, and moves from the front lower part of the machine toward the rear upper part of the machine. The structure is such that the stem culms that are not to be harvested on the side are separated from the stem culms that are introduced into the reaping device 2, and the grass is separated to the side of the machine body.

Reference numeral 7 in the figure indicates a grass cutting rod that is located high in the rear upper part of the aircraft and moved away from the grass cutting device 8 toward the outside of the aircraft structure. This is to guide the stem culms that are not to be harvested to the outside of the mechanism.

The structure is such that even if the stem culm lies down in a state in which the tip is moved in the transverse direction and the stem culm lies down along the direction of movement of the aircraft, it can be engaged with the claws 1a and pulled up.

The rotation axis P at the lower front end of ... is raised and the device 1 side is tilted higher, and as shown in FIG.・Latching claw 1a of the vertical rotation movement locus R2 of the lifting device 1...
It is configured to overlap the sideways movement locus R1 of
The locking claws 9 of the weeding device 8 are configured so that they can be moved and locked in the lateral direction on the action starting end side.

The movement locus R2 of the locking claws 9 of each of the weeding devices 8 is configured such that the further backward in the moving direction thereof, the closer to the movement trajectory R1 of the locking claws 1a of the pulling device 1. At the action starting end side, a component force is generated in the lateral and lateral directions as it rotates, so that the locked stem culm is easily pushed out and guided to the outside of the mechanism.

In the above-described embodiment, instead of the central weeding tool 10, a weeding device 8 may be provided which is vertically rotated around an axis that is substantially horizontal to the ground.

The present invention is applicable not only to combines but also to various types of reaping machines such as binders.

Note that there is a dead space between the horizontal movement locus R1 of the locking claw 1a of the pulling device 1 and the vertical movement trajectory R2 of the locking claw 9 of the weeding device 8. To eliminate S,
For example, as shown by the two-dot chain line in FIG. It is possible to move the locking claw closer to , but the locking claw 9 does not move laterally
There is a drawback that it cannot work effectively against stem culms that are collapsed along the direction of the aircraft's movement.

In summary, the present invention, in a snow-covered reaper, tilts the vertical axis P of the locking pawl 9 of the weed splitting device 8 so that the pulling device 1 side is higher, and when viewed from the front,
In the horizontal movement locus R1 of the locking claw 1a of the lifting device 1,
It is characterized in that the vertical movement locus R2 of the locking claw 9 of the weeding device 8 overlaps.

In other words, by tilting the weeding device and making the moving trajectories R1 and R2 of the weeding claws 1a and 9 overlap, it is possible to securely move either of the weeding claws 1a and 9 to the stem culm. By using this method, we have been able to reliably prevent uncut areas that are caused by the snow-covered tread space of the conventional type.
