Description

[Detailed description of the invention] The invention includes a forced pulling device that moves a claw protruding in a direction perpendicular to the direction of movement of the aircraft from below to above;
This reaper is equipped with a forced weeding device for moving claws projecting in the direction of movement of the machine body from below to above on the same side of the path for introducing stem culms into the reaping device.

In the above-mentioned reaping machine, as the machine advances, the forced weeding device that has a locking pawl that drives and moves the target stem culm and non-target stem culm to be reaped can reliably divide the grass. Although this is advantageous, the lodging stem culm may get into the gap created between the chain cases of the pulling device for pulling up the reaped stem culm and the forcible weeding device, and the fallen stem culm may be caught and damaged. Or, there was a drawback that one of them could not be harvested.

The present invention aims to eliminate such drawbacks and also to increase the strength of these chain cases themselves, which are formed relatively long.

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

At the front part of the machine body equipped with the crawler traveling device 1, a pre-processing section 5 consisting of a forced planting culm pulling device 2, a reaping device 3, and a reaped culm conveying device 4 is rotated up and down around the horizontal axis P1. At the rear of the machine, a threshing device 6 and a feed chain 1 attached thereto thresh the cut husk from the conveying device 4, and bag the threshed grains. This is a combine harvester for reaping and threshing culms without running the machine.

A locking pawl 8 is attached to a chain 8a that is wound around a wheel that rotates around a horizontal axis P2 and a wheel that freely rotates around an axis I that is parallel to the axis P2. The forced weeding device 9 is of a so-called vertical type in which the locking pawls 8 are made to protrude from the upper part of the chain case and are driven and rotated.

This weeding device 9 is attached to the outside of the pulling device 2 on the (uncut) side where the feed chain I is installed, and the stem culm to be reaped which is lying down outward from the stem culm introduction path A side and The system is configured to lift each stem culm not to be harvested that is about to fall into the stem culm introduction route A side from the outside, and to separate the stalk culms to be harvested to the route A side and the non-target stalk culms to the outside. It is composed.

The front and rear axis P3 The wheel that drives and rotates around the housing and this axis P3
A chain 10a that is wound around a ring body that freely rotates about an axis parallel to 1 is provided with lifting pawls 10, and these lifting pawls 10 are made to protrude and stand up from the inner edge of the chain case 11. The stem culm in the stem culm introduction path A is raised by driving and rotating the stem culm.

The chain case 11 is constructed by combining three case pieces, and the husband chains 8a and 10a of the lifting and weeding devices 2 and 9 are arranged in the same case space, resulting in a compact structure. .

In other words, by arranging the chain cases of the pulling and weeding devices 2 and 9 in a series, the stem culms do not get stuck between these cases, and the cases are reinforced with each other to increase the strength. It is designed to enhance the performance.

One piece of the chain case 11 is tilted from the weeding device 9 toward the pulling device 2 side, and this sloped side 11a is
The structure is such that the stem culm in contact with the culm can be smoothly transferred to the pulling device 2 side as the body advances.

In summary, the technical feature of the present invention is that the forced pulling device and the forced weeding device are housed in one case, which provides the following effects.

In other words, by connecting the chain cases of the pulling device and the weed splitting device, it is possible to eliminate the gap between these cases, so it is possible to eliminate the possibility of damaging the stem culm by pinching it in the gap, or leaving only one of them. Not only was it possible to suppress poor harvesting such as storage, but also the strength of the relatively long case itself could be increased because of the integral connection.
