Therefore, the cereal culm bundle is damaged and the cutting and bundling work is efficiently performed. There was a problem that it could not be done.

[0004]

Therefore, according to the present invention, a binding device includes a left cereal culm releasing means for releasing a cereal bundle to the left and a right cereal culm releasing means for releasing a cereal bundle to the right. A cutting and binding machine that selectively releases the bound grain stalk bundle to the left or right, and is linked to the left grain stalk releasing means and the right grain stalk releasing means on the handle side at the rear of the body. A hand operating device for switching the operation is provided, and when one of the cereal stalk releasing arms of the cereal stalk releasing arm of the left cereal stalk releasing means and the cereal stalk releasing arm of the right cereal stalk releasing means is released, the other is released. Of the cereal stem release arm in the standby position, and the cereal stem release arm in the standby position among the left and right cereal stem release arms operates the cereal stem release arm on the release operation side. Grain stalk configured to lie outside the trajectory In the output device, a binding device driving input shaft for driving the binding device is protruded substantially vertically from a binding transmission case constituting the binding device, and the binding device driving input shaft is covered by an input shaft pipe. At the upper position of the input shaft pipe, a tip guide that can be switched to the left or right to guide the grain stalk tip toward the release direction is disposed, and the left tip is released along the switched tip guide. Only one of the passage and the right discharge passage is formed, and the operation trajectory of the cereal stalk release arm on the release operation side is the tip of the cereal stalk release arm on the release operation side at the standby position, and the tip guide. And a stalk releasing device in a cutting and tying machine, characterized in that the device is formed on a discharging passage formed along the same ear tip guide.

[0005] It is also characterized in that the tip discharge portions of the left and right grain stem release arms are configured to be stepped from each other.

The embodiment of the present invention is configured as described above. When the cutting and binding machine A is advanced to perform the cutting operation of the grain culm, the power is transmitted to the cutting device 6 and the binding device 7 to transmit the grain. While cutting the culm, unite the cut culm by a fixed amount. Then, when releasing the bound grain stalk bundle to the left side of the body, the hand operation device 30A is operated to make only the left grain stalk releasing means 12a operable, and the stock origin is guided in conjunction with this. The switch body 21 and the tip guide 24 for guiding the tip are switched to the left. Therefore, the cereal stem bundle is pushed out by the left cereal stem releasing means 12a, and is simultaneously guided by the switching body 21 and the tip guide 24 to be smoothly released.

In this case, when the switching body 21 is switched to the left, the on / off mechanism 55 provided on the drive mechanism 54 on the left culm release arm 12 side operates.

When the bundle of culms is to be discharged to the right side of the machine body, the hand-held operation device 30A is switched to operate in the opposite manner. Then, only the right cereal stem releasing means 16a is made operable, and the switching body 21 and the tip guide 24 are exchanged rightward in conjunction with this.

As described above, according to the above-described embodiment, the left grain releasing means 12 for releasing the grain bundle to the left in the binding device 7.
a and a right culm releasing means 16a for releasing a cereal bundle in the right direction, and in a cutting and binding machine for selectively releasing the bound cereal bundle to the left or right, a handle 31 at the rear of the machine body is provided.
In addition, the left cereal stem release means 12a and the right cereal stem release means 16a
And a hand operating device 30A for switching the operation by interlocking with the cereal stalk releasing arm 12 of the left cereal stalk releasing means 12a and the cereal stalk releasing arm 16 of the right cereal stalk releasing means 16a. When the culm releasing arm 12 (16) is in the releasing operation, the other cereal culm releasing arm 16 (12) is configured to be in the standby position in the stopped state, so that the cereal culm releasing means of one of the cereal culm releasing means is released. When the arm 12 (16) is performing the release operation,
The culm releasing arm 16 (12) on the other side is securely stopped, and the releasing action of the tied cereal bundle is reliably performed. Further, since the left and right grain stalk release arms 12 (16) are on standby outside the operation trajectory K1 (K2) of the cereal stalk release arm 12 (16) on the release operation side when stopped, the stalk culm release arms 12 (16) (16)
The release of the stalk bundles is always performed in a stable state.

Further, since the tip discharge portions 12-1 and 16-1 of the left and right cereal stalk release arms 12 and 16 are configured to be stepped at different heights from each other, when releasing the culm bundles. The left and right grain stalk release arms 12, 16 do not contact and damage the grain stalk bundle.

The cutting and bundling work can be performed efficiently while the structure is simple as a whole.

[0035]

According to the present invention, the binding device driving input shaft for driving the binding device is projected substantially vertically from the binding transmission case constituting the binding device, and the input device for driving the binding device is provided. The shaft was covered with the input shaft pipe, and a tip guide that was switchable to the left or right to guide the grain stalk tip toward the release direction was disposed above the input shaft pipe and switched. Only one of the left discharge passage and the right discharge passage is formed along the tip guide, and the operation trajectory of the cereal culm discharge arm on the discharge operation side is set at the standby position. Discharge of the grain stalk bundle by the grain stalk release arm, because the tip and the tip guide, between the tip guide, is configured to be formed on the release passage formed along the tip guide, Always stable through the discharge passage With the ropes grain 稈穂 destination unit is guided by the tip guide, the release of cereal 稈束 can be smoothly through the discharge passage.

Further, since the leading end discharge portions of the left and right cereal stem releasing arms are formed in a stepped shape with different heights, the left and right cereal stem releasing arms come into contact with each other when releasing the cereal bundle. It does not damage the stalk bundle.

The cutting and bundling operation can be performed efficiently while the structure is simple as a whole.
