3 and the clutch gear 19, the sprocket 107 that is transmitted to the scraping rotor 93 of the cutting device 91
The scraping rod 1 has a small tooth ratio between the sprocket 101 and the scraping rod 1 that rotates via the scraping rotor 93 of the cutting device 91.
9 is made to rotate faster than the rotation of the packer 25 of the binding device 1.

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

When the clutch 121 is slid to the left in FIG. is connecting rod 53
It swings around the shaft 29 while being supported at one end by the grain culm passage 7, and pushes the grain culm in the grain culm passage 7 between it and the T protrusion 33.

When the grain culm reaches a predetermined pressure, the T protrusion 33 rotates, and the clutch device 37 operates to shift the gear 35 to the clutch gear 1.
9, and the 21 dollar 4
7 is swung, the binding string is passed over the grain culm passage 7, wrapped around the grain culm, and fed into the knotter part 11.

At the same time, sprocket 43, sprocket 85, and transmission shaft 8
1, Sprocket 87, Chain 89, Sprocket 63
The binding shaft 57 is rotated through the knotter bill 69 to bind the binding cord, which is then cut, and the bound grain culm is pushed by the swinging of the discharge rod 75 and discharged outside the machine.

When the above operation is completed, the clutch device 37 is shut off to its original state with the T projection 33 and needle 47 returned to their original positions.

During the above-mentioned binding operation, the cutting device 91 is not in operation, so it does not interfere with the binding operation.

When performing cutting work, when the shifter 121 is slid to the right in FIG.
07, and the power of the input shaft 13 rotates the raking rotor 93 via the sprocket 107, chain 103, sprocket N 01, and cylinder 97, and the raking rod 109 moves the grain culm to the rotor. Scratch between 115 and 115.

The rotor 115 has a gear 99, a gear 119, and a shaft 117.
Rotationally driven through.

The grain culms sent by the scraping rotor 93 and the rotor 115 are shredded by the cutter 105 and discharged outside the machine.

During the cutting operation, the raking rod 1 rotates via the raking rotor 93 as the Pasocar 25 of the binding device 1 rotates.
Since the rotation of 09 is faster, the grain culm is raked in by the raking rod 109 and is not pressed against the T projection 33 by the packer 25, so the T projection 33 does not operate unexpectedly and smooth cutting is achieved. Able to perform work.

As described above, the present invention provides a tying device in which a twenty dollar part for wrapping a tying string around a grain culm and a knock part for tying the tying string are provided facing each other through a grain culm passage. , in a binding device equipped with a cutting device in which a cutting device for cutting grain culms is integrally built into one side lower part of the grain culm passage, rotation of a rake rod of the cutting device is controlled by a packer of the binding device. Since the rotation speed is faster than the rotation speed of the tying device, it is possible to prevent the grain culm from pressing against the T protrusion during the cutting operation, and therefore the T protrusion of the binding device does not operate unexpectedly.
