Abstract

PURPOSE:To ensure the release of grain straw bundles by subjecting the other grain-releasing arm to a stopping operation, when one grain-releasing arm is subjected to a releasing operation. CONSTITUTION:An operation device at hand is operated to operate only a left side grain straw-releasing means 12a, and a switching member 21 for guiding the roots of the grain straws and an ear tip guide for guiding the ear tip parts of the grain straws are switched in the left direction with interlocking with the operated left side grain release means 12a. The bundles of the grain straws are thereby pressed out by the left side grain straw release means 12a and simultaneously guided and smoothly released out by the switching member 21 and the ear tip guide.

The embodiment of the present invention is constructed as described above, and when the reaping and tying machine A is moved forward to reap grain culms, power is transmitted to the reaping device 6 and the tying device 7 to remove the grain. While harvesting the culms, the harvested grain culms are tied together in a certain amount. When the bundled grain culm bundle is to be released to the left side of the machine, the hand control device 30A is operated to enable only the left grain culm release means 12a to be operated, and in conjunction with this, the stock is guided. The switching body 21 and the tip guide 24 that guides the tip portion are switched to the left. Therefore, the grain culm bundle is pushed out by the left grain culm discharge means 12a, and at the same time is guided by the switching body 21 and the ear guide 24 to be smoothly discharged.

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

In the on/off mechanism 55, as shown in FIG.
As shown in FIG.
The crank arm 54-4 and the left grain culm release arm 12 can be freely operated in conjunction with the operation of the clutch shaft 44.

When the grain bundle is to be discharged to the right side of the machine, the hand control device 30A is operated in the opposite manner to the above. And the right grain culm discharge means 1
Only 6a can be freely operated, and in conjunction with this, the switching body 21 and the tip guide 24 are changed to the right.

As described above, according to the above embodiment, the left grain culm discharging means 1 for discharging grain culm bundles to the left is attached to the binding device 7.
2a and right grain culm discharge means 1 for discharging grain culm bundles to the right.
In the reaping and tying machine which selectively discharges the bundled grain culm bundles to the left side or the right side, the left grain culm discharge means 12a and the right grain culm discharge means 16a are provided at the handle 31 at the rear of the machine body. A hand-operated device 30A is provided to switch the operation of the grain culm discharging means 12a and 16a of the left grain culm discharging means 12a and the grain culm discharging arm 16 of the right grain culm discharging means 16a, respectively. Since the discharging arm is a grain culm discharging device in a reaping and tying machine configured such that the other grain culm discharging arm is in a stopped state when the discharging operation is performed, the grain culm discharging arm of the grain culm discharging means on one side performs the discharging operation. When the grain culm release arm on the other side is stopped, the bundled grain culm bundle is reliably released. In addition, when the left and right grain culm release arms are stopped, they wait outside the operating trajectory of the grain culm release arm on the release operation side, so that the grain culm release arms release the grain culm bundles in a stable manner at all times. It is something.

Furthermore, left and right grain culm release arms 12, 16
The tip discharging parts 12-1, 16-1 are configured in different steps with different heights, so that when the grain culm bundle is discharged, the left and right grain culm discharging arms 12, 16 come into contact with each other and the grains are released. It does not damage the culm bundle.

[0034] Although the structure is simple as a whole, the cutting and tying work can be carried out efficiently.

[0035]

[Effects of the Invention] As explained above, according to the present invention,
The tying device is provided with a left grain culm discharge means for discharging the grain culm bundle to the left and a right grain culm discharge means for discharging the grain culm bundle to the right. In a reaping and tying machine that selectively discharges, there is a
A hand-operated device is provided that is interlocked with the left grain culm discharge means and the right grain culm discharge means to switch their operation, and also controls the grain culm discharge arm of the left grain culm discharge means and the grain culm discharge device of the right grain culm discharge means. The grain culm discharge device of the reaping and tying machine is configured such that when one grain culm discharge arm among the arms is in a discharging operation, the other grain culm discharge arm is in a stopped state. When the culm discharging arm is performing the discharging operation, the grain culm discharging arm on the other side is reliably stopped, and the discharging action of the bundled grain culm bundles is reliably performed. In addition, the left and right grain culm release arms are
When stopped, the grain culm discharge arm waits outside the operating locus of the grain culm discharge arm on the discharge operation side, so that the grain culm discharge arm releases the grain culm bundles in a stable state at all times.

Furthermore, since the tip discharging parts of the left and right grain culm discharging arms are configured in a staggered manner with different heights, the left and right grain culm discharging arms do not come into contact with each other when the grain culm bundle is discharged. It does not cause damage to grain culm bundles.

Although the overall structure is simple, the cutting and tying work can be carried out efficiently.
