Description

[Detailed description of the invention] This invention relates to a culm guide of a culm cutter that cuts the threshed culm of a mobile threshing machine such as a combine harvester or a harvester, and is intended to smoothly cut and discharge the culm.

Therefore, this invention has the following technical effects.

That is, a sheet-like member is attached to the culm opening 6 of the cutter 5, which has a large number of disc blades 3° 4 arranged in the directions of the shafts 1 and 2, and cuts the culm that is fed parallel to the shafts 1 and 2. A culm cutter comprising a discharge guide 8 having a lower lower end, which forms an inclined surface that gradually narrows toward the bottom, and has a swingable free end at the lower end. The configuration of the ejection guide is as follows.

With this configuration, this invention has the following technical effects.

In other words, with a cutter having a large number of disk blades 3 and 4 arranged in the axial direction, the cut culm falls in a thin layer over a wide area, and is easily spread by the wind9, especially when used in combine harvester operations. However, since the discharge guide 8 made of a sheet-like member with a narrowed lower end is provided as described above, the discharge guide 8 is provided with a sheet-like member with a narrowed lower end, so that the discharge guide 8 is not cut and falls. The cut culm is collected at the lower end lower end and dropped, and this sheet-like member cushions the impact of the culm being thrown away when it is cut, and the discharge guide 8 is easily shaken by vibrations, wind pressure, etc. during running. This rocking motion allows the cutting culm to be guided to fall from the lower end opening smoothly without any clogging, and even if the culm guide 8 comes into contact with a high ridge, it can escape, with minimal damage and as much as possible. By extending downward, collection and dropping can be performed accurately from all around the front, back, left and right, and moreover, it is safe.

In addition, as shown in the figure, 9 is a threshing device of a combine harvester, and a cutter 5 is detachably installed on the rear side of the culm removal part 10.

11 is a crawler. The cutter 5 is provided with a pair of parallel shafts 1 and 2 along the culm body of the culm.
Disk blades 3 and 4 are arranged at a constant cutting interval on 2, and cut the culm that is supplied from the supply port 12 between both the disk blades 3 and 4.

The discharge port 6 is opened at the lower side of the case 13 of the cutter 5, and the upper edge of a discharge guide 8 made of a sheet-like member is detachably attached to the lower edge of the case 13.

The discharge guide 8 is made of a vinyl sheet, cloth, etc., and its upper edge surrounds the discharge port 6, and its lower edge gradually narrows toward the lower end, with the lower end opening toward the center of the width of the machine. There is.

14 is a hook fixed to the case 13, and 15 is a hook of the discharge guide 8 that can be hooked to the hook 14.

When not in use, the hook 15 may be engaged with the hook 14 and the discharge guide 8 may be folded up.
