Description

[Detailed description of the invention] The present invention uses a cutting section to cut and harvest the straw grass, while cutting off the short grass mixed in the grass, and cutting the straw grass into the scraps that come out. This invention relates to an improvement on a straw harvester that is equipped with a pickling device and a cutter on the machine body so that it can be processed and discharged.

The pickling device installed on the body of the rush harvesting machine is designed so that the pickling teeth, which rotate in the direction of the culm of the rush, act on the rush that is being held in the panicle side. placed inside.

In addition, the cutter for cutting and cutting the straw that has been picked out by the picking device is designed so that the short straw that is picked out by the picking device can be received as it is into the receiving port and processed for cutting. Placed in front of the direction.

For this reason, if the rush from the pickle dregs that is picked out by the pickling device and headed for the cutter is even slightly tangled with the normal-sized rush that is held at the tip side by the pick-picking and conveying device, it will follow the normal rush. This tends to cause the tip to be dragged in the conveyance direction of the tip holding and conveying device, and not to be supplied to the cutter.

Therefore, at the outlet of the pickling device, the rush that has been picked out is forcibly pulled out in the direction of the picking direction, which is the culm of the rush, and the tip side is held in the pickling device. It is desirable to provide a means that can separate the straw from the grass, and the means is to use a feed-out roll consisting of two counter-rotating rolls such that the feed-out direction due to the opposing gap between the feed-out rolls is in front of the feed direction. It is effective to dispose the rice cake so that the strawberry from the goose residue that is being taken out is fed out from the feeding side of the feeding roll to the receiving and feeding side.

However, installing the feed roll at the outlet of the pickling device not only complicates the mechanism of the rush harvester, but also makes the cutter installed in the front of the pickling device This creates the problem of increasing the length of the machine because it has to be pulled away from the scoring device forward in the direction of picking out.

Therefore, the purpose of the present invention is to solve this problem and to ensure that the rush that is picked out from the pickling device is separated from the normal rush.
The cutter disposed at the front in the cutting direction of the scoring device is configured as a cylinder type cutter having two feed rolls at its receiving opening. By arranging the cutter so that its axial direction is along the conveyance direction of the ear tip holding and conveying device and facing the exit part of the scoring device, the cutter can be picked up from the picking device by the feeding action of the feed roll of the cutter. Try to pull out the gourd grass that comes out from the normal straw,
The present invention proposes a means for reliably separating currant rice grass from normal rice grass without using the above-mentioned feed roll.
