Description

[Detailed Description of the Invention] This invention relates to a binding device equipped with a cutting device for cutting the culm.

The object of this invention is to provide a bundling device equipped with a cutting device that can easily scrape harvested culms into the cutting device during the cutting operation.

FIG. 1 shows the entire binding device 1, which is secured to a combine harvester (not shown) by a locking portion 3, penetrates a coupling hole 5, and is attached with a bolt.

The shell culm that has been threshed by a threshing device (not shown) is sent through the shell culm passage 7 in the direction of arrow A, and the shell culm is sent in a posture perpendicular to arrow A.

9 is a needle portion provided below the culm passage 7;
The packer 13 is swung along a predetermined trajectory by a transmission device installed in the packer 13, and the culm in the culm passage 7 is pushed into the space between the packer 13 and the T projection 15.

When the culm reaches a predetermined pressure, the T protrusion 15 rotates, and in conjunction with this, the needle 17 is swung to wrap the binding string around the culm across the culm passage 7, and at the same time, the following knock button Send it to Department 19.

The knotter part 19 is provided above the culm passage 7 and is used to tie the binding cord.

Reference numeral 21 denotes a cutting device for cutting the shell culm provided below one side of the shell culm passage 7. A transmission device built into the main body 11 rotates a scraping rotor 23, and a scraping rod 25 folds the shell culm in two. The material is then scraped between the scraping rotor 23 and the rotor 24 which rotates opposite to it, and is shredded by a rotating cutter 27.

As shown in FIG. 4, the raking rod 25 is positioned so that its trajectory a is closer to the threshing device, which is the front side in the transport direction of the culm, than the trajectory of the packer 13 of the bundling device 1. As shown in FIG. 6 and FIG.
1, and rotates while moving in and out as the scraping rotor 23 rotates.

Reference numeral 33 denotes a clutch slidably provided on the human-powered shaft 35 via a key 37, and a claw portion 39 provided on the side surface is a clutch provided on the side surface of a sprocket 41 rotatably fitted to the input shaft 35.
3 in a detachable manner.

A shifter 45 is pivotally attached to the main body 11 by a shaft 47, and is fitted into a groove 49 provided on the outer periphery of the clutch 33 to cause the clutch 33 to slide.

51 is an input sprocket fixed to the input shaft 35, which transmits power to the binding device.

In the above configuration, the shell culm that has been threshed by the threshing device (not shown) of the combine harvester is sent to the shell culm passage 7 from the direction of arrow A in FIG. 1 in a posture perpendicular to the direction of movement.

Now, when performing the binding work, the clutch 33 must be
When the input shaft 35 is slid to the right in the figure, the power of the input shaft 35 operates the binding device 1 via the input sprocket 51 and the chain, and the packer 13 scrapes the culm in the culm passage 7.
It is pressed between the protrusion 15 and the projection 15 .

When the culm reaches a predetermined pressure, the T-protrusion 15 rotates and swings the needle 17 via the transmission device, wrapping the binding string around the culm across the culm passage 7 and tightening the knot 1.
Send it to 9.

After tying the tying string with the knot vine part 19, the tied culm is discharged to the outside of the machine.

During the above-mentioned binding operation, the cutting device 21 does not operate because power is not transmitted to the sprocket 41.

When performing the disconnection operation, when the clutch 33 is slid to the left in FIG.
1 and the cutting device 21 is operated via the chino, the scraping rotor 23 is rotated, and the culm is cut into two by the scraping rod 25.
It is folded and scraped between the scraping rotor 23 and the rotor 24 that rotates opposite to it, and is shredded by the cutter 27 and discharged outside the machine.

Even if the packer 13 of the bundling device 1 operates during the above-mentioned cutting operation, the culm is not moved by the raking rod 25 because the swing locus of the raking rod 25 is located closer to the threshing device than the oscillating trajectory of the packer 13. Since the T-protrusion 15 is not subjected to pressure from the culm, the T-protrusion 15 will not operate unexpectedly.

As is clear from the above, this invention includes a binding device and a cutting device that are arranged in parallel in the direction of the culm of the culm to be transferred, and a device that rotates in the direction of transport of the culm and connects the culm to the T protrusion of the binding device. In a bundling device equipped with a cutting device that has a packer that presses between the packer and a raking rod that scrapes the culm into the cutting device, the raking action of the raking rod precedes the raking action of the packer. Since the rotation locus of the raking rod is made to protrude toward the front in the transport direction of the culm than the rotation trajectory of the packer, the rotation of the raking rod in conjunction with the rotation of the packer during cutting operations prevents the raking rod from scratching. The culm can be scraped in by placing the filling in advance of the scraping action of the packer.

Therefore, the cutting device can be easily scraped into the cutting device, and problems such as the culm being scraped by the packer toward the T protrusion and the T protrusion being pressed and causing malfunction can be minimized.
