Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a combine harvesting and collecting apparatus, which is used for harvesting and harvesting rice, wheat, soybeans, adzuki beans, etc., and conveys and feeds the whole harvested grain culm to a threshing unit for threshing. It can be used as a combine harvester.

[0002]

2. Description of the Related Art A mowing device of a combine harvester is moved to the left or right with respect to a feed conveyor on the side of a threshing device, or a mowing device having a different harvesting width is attached or detached. Therefore, depending on the type of harvested culm and other harvesting conditions, etc., highly versatile and adapted harvesting harvesting is performed.

In the conventional combine harvester, the cutting blade device, the auger for collecting the cut grain culms, and the like have a fixed width and are located at a fixed position with respect to the feed conveyor. If you move the cutting blade device, auger, etc. to the feed conveyor in the left-right direction, it will be difficult for the auger to transfer the grain culms to the feed conveyor smoothly. Even in the form of preparing and attaching and detaching, since the connecting position of the auger with respect to this feed conveyor is constant,
The mounting position is limited.

[0004]

According to the present invention, a front portion having a width wider than the rear auger 2 is provided along a front side of a rear auger case 3 accommodating a rear auger 2 for collecting the harvested grain culms to a rear feed conveyor 1. A front auger case 6 accommodating the auger 4 and having a cutting blade device 5 on the front side is configured as a combine harvesting and feeding device in which the left and right positions can be changed and the detachable connecting device is continuously provided.

[0005]

In the cutting and harvesting work, the grain culms cut by the cutting blade device 5 are the front auger case 6
Inside, it is collected by the rotation of the front auger 4 and supplied into the rear auger case 3 on the rear side. In the rear auger case 3, rotation of the rear auger 2 sends the collected grain culms to the feed conveyor 1, and the feed conveyor 1 conveys and feeds the collected grain culms to the threshing device.

When changing the left and right position of the cutting blade device 5 with respect to the feed conveyor 1 or the traveling device, the front auger case 6 is moved in the left and right direction, or the front auger case having a different cutting width is replaced. The cutting position, the cutting width, etc. can be changed by means of this, but in such a case, the connecting position between the front auger case 6 and the rear auger case 3 can be freely set within a certain width range. The rear auger case 3 has a fixed grain culm inheriting position with respect to the feed conveyor 1, and therefore the front auger 4
In addition to the transfer of the grain culms sent in to the rear auger 2,
The supply from the rear auger 2 to the feed conveyor 1 can be smoothly and stably performed.
