Description

[Detailed description of the invention] The present invention is equipped with a device that forcibly divides the planted stem culms into objects to be harvested and non-target objects, and also presses the planted stem culms that are not targeted for reaping to the outside of the mechanism. Relating to a reaper equipped with a grass divider.

In the above-mentioned reaping machine, the planted stem culm is forcibly divided into the target and non-target objects, and the non-target target is subsequently pushed outward from the machine structure by the fixed weeding rod, so that the weeding is ensured. However, in the past, when the non-target stem culm was being acted on by a forced weeding device, it was pressed by a weeding rod, so the tips of the ears were strongly squeezed by the forced weeding device. , there were problems such as grain shedding.

The present invention aims to solve this problem.

Embodiments of the present invention will be described in detail below with reference to illustrative drawings.

At the front of the machine body equipped with a crawler-type traveling device 1, there is a reaping section 2 for raising planted stem culms, reaping them, and transporting the reaped stem culms.
A threshing section 5 is provided in the center of the machine body to perform threshing processing in cooperation with a feed chain 3 and a threshing device 4 and to transfer the threshed grains to a bagging section. A combine harvester, which is an example of a reaping machine, is provided with a shredding device for discharging the cut material to the outside of the machine body.

The reaping section 2 includes a wheel 6 that rotates around a horizontal axis,
A chain 8 is wound around the chain 8, which is rotatably pivoted around the pawls 7 at appropriate intervals, and a pawl raising regulation plate 9 allows the pawls 7 to rotate as the chain 8 rotates.・・・・・・
This is a forced weeding device 10 that is configured to move in an upright state over a certain range, and forcibly separates planted stem culms into objects to be reaped and objects not to be reaped.

At the rear of this forced weeding device 10, a lifting pawl 12 is rotated at an appropriate interval on a wheel 11 that rotates around the longitudinal axis of the machine. A movably attached chain 13 is wound around the lifting claw 12 to raise and move it over a certain range using the raising regulation plate 14, thereby constructing a pulling device 15 for raising the stem culm to be reaped. be.

Grass 17 is connected and supported to a support 16 on the horizontal side of the machine body of the forced weeding device 10 that supports the lower end of the pulling device 15 at the rear, and the grass 17 is pulled up and separated. The target stem culms should be pressed outward to the side of the aircraft, and the non-target stem culms should be pressed and divided so that they do not fall down toward the aircraft.

The action starting end position of the weeding rod 17 is set to the forced weeding device 10.
is set near the end position of the action of the weeding rod 7 to act on the stem rod being raised by the forced weeding device 10 to press the stem culm outward from the machine body, thereby creating a squeezing action on the tip of the ear. It is designed to avoid this.

The form of the forcible weeding device 10 can be modified in various ways, such as by providing one rotary wheel body or a plurality of upper and lower stages of rotating wheels each having a raised protrusion.

In summary, the present invention is characterized in that, in the above-mentioned reaper, the starting position of the pushing action of the weeding rod is set near the action end position of the forcible weeding device in the longitudinal direction of the machine body. .

In other words, by forcibly pulling up the stem culm that is not to be harvested, or by applying the force of the divider rod near the position where the pulling is completed, the strong squeezing effect on the tip of the ear caused by pressing while lifting is suppressed. This makes it possible to effectively suppress the damage to the tip of the ear caused by weeding, which previously occurred frequently.
