Description

[Detailed Description of the Invention] The present invention relates to a binding device for bundling a fixed amount of harvested grain culms or threshed grain culms and tying them with a string.

In general, this type of grain culm binding device is
As proposed in Publication No. 55-1004, etc., the grain culms are collected in front of the door arm by the swinging of the packer, and when this amount of collection reaches a predetermined amount, the door arm is rotated by the pressure of the packer. The clutch is actuated by the rotation of this door arm, and at the same time the swinging of the packer is stopped, the needle moves toward the building and the holder, thereby binding the collected grain culms. When the grain culms are bundled in the step, the bundled grain culms are pressed against the door arm by the force of the packer.

Therefore, the concentrated grain culm at the door arm location is
Due to the above-mentioned pressing of the packer against the door arm, the attitude of the grain culm is displaced in a direction perpendicular to the direction of the culm, and this displacement of attitude causes the tip of the bundled grain culm to spread out. There were many problems with the door arm operating at unexpected times.

In view of the current situation, the present invention aims to prevent the grain culms converging on the door arm from changing their posture due to pressure from the packer.

For this reason, the present invention is a bundle consisting of a knot having a bill and a holder on one side of the grain culm passage, and a focusing and discharging section having a door arm, a needle, a packer and a discharging arm on the other side. In the device, a guide rod made of an elastic material is provided at a position near the tip of the grain culm on the knot side side of the grain culm passage, and a free end of the guide rod is directed toward the exit of the grain culm passage. Once installed at the proximal end so as to project inwardly, the discharging arm is also provided with a grain culm support rod made of an elastic material at a position near the tip of the grain culm, and the free end of the grain culm support rod is attached to the ejection arm. is attached at the base end so as to intersect with the guide rod.

The present invention will be explained below with reference to drawings of an embodiment in which the present invention is applied to a binding device in a reaping and binding machine (binder). 2 shows a reaping tying machine in which an engine 4 and a control handle 5 are each attached to a reaping tying section 7 through a pipe-like frame 6 extending forward, and a string coil 8 is placed in the middle of the reaping tying machine. Cover 1 with part 9

The reaping binding section 7 includes a pair of left and right weeding bodies 11,
12, a grass cutting guide body 13 extending rearward and diagonally upward from the rear of one grass cutting body 11, a grain culm pulling mechanism 14 extending rearward and diagonally upward from the rear of the other grass cutting body 12, and both said grass cutting bodies 11, 12. It consists of a reaping mechanism 15 located at the rear of the lower part of the grain culm, and a binding device 16 located at the rear of the grain culm lifting mechanism 14.

The binding device 16 connects the pipe-shaped frame 6
A binding case 17 attached to the right side of the binding case 17, and a bearing case 1 protruding upward from the top surface of the binding case 17.
8 and a knotted shaft 1 pivotally supported within this bearing case 18.
9, a clutch shaft 21 supported in parallel to the knot shaft 19 in the binding case 17, a hollow door shaft 22, and a power input shaft 23 to the binding device 16. The knot part 20 includes a building 25 driven by the knot shaft 19, a holder 26, and a knot cover 27 attached to the bearing case 18 so as to surround these. The output shaft 28 to the grain culm pulling mechanism 14 is pivotally supported, and the gear 29 is fitted onto the input shaft 23 in the bundling case 17.
The clutch gear 30 that is always engaged with the clutch shaft 2
1 and the sprocket 31 which is rotatably fitted to the clutch gear 30 and is integrally provided with the clutch gear 30, and the output shaft 28.
A chain 33 is wound between the sprocket 32 and the input shaft 23 to transmit the rotation of the input shaft 23 to the output shaft 28. In this case, a grain culm passage 34 is formed between the focused discharge part 24 and the knot part 20.

The focusing and discharging section 24 includes a packer 35, a needle 36, a door arm 37, and a discharge arm 38.
While the base end is swingably connected to the clutch shaft 21 via a link 40, the tip of the packer 35 is rotated by the rotation of the input shaft 23 as shown in FIG. It is configured to oscillate in the direction of the arrow along the trajectory shown by
The needle 36 has its base end connected to the door shaft 22.
A curved link 44 is rotatably supported on a discharge shaft 42 which is rotatably fitted in the clutch shaft 21, and a curved link 44 has a pin 43 pivoted near its base end. Rotatably supported on a pin 46, the tip of the needle 36 moves forward toward the knot 20 and then moves backward to the original position by one rotation of the clutch shaft 21, and the forward movement is stopped. At the time, both ends of the string drawn out from the string coil 8 and passed through the tip of the needle 36 are tied with the bill 25 and the holder 26, and then cut.

The door arm 37 is attached to a boss body 47 fitted to the upper end of the hollow door shaft 22 with a bolt 48 so as to protrude toward the knot 20 at a lower height position than the needle 36 and the ejection arm 38. ing. Further, the release arm 38 is
The needle 36 is formed wide in the vertical direction.
At a higher position, the release shaft 42 is fixed to the upper end of the door shaft 22, and the release shaft 42 is tied to the clutch shaft 21.
0,51 is transmitted so that one rotation of the clutch shaft 21 causes the ejection arm 38 to rotate once in the direction of arrow 52 from the solid line position outside the door arm 37 in the plan view of FIG. 3, and to stop at the original solid line position. while the door arm 37 of this ejection arm 38
A bundle support 53 is attached to the inner side surface by fastening bolts 54.

Inside the binding case 17, the door shaft 2 is disposed between the hollow door shaft 22, the input shaft 23, and the clutch shaft 21.
When the door arm 37 attached to the door arm 37 rotates at an appropriate angle in the direction of the arrow 56 from the position shown by the solid line in FIG. 57 is provided, and the door arm 3
7 is configured so that during one rotation of the clutch shaft, it rotates in the direction of arrow 56 to the position shown by the two-dot chain line, and then returns to the original position by the force of a spring (not shown). Furthermore, the rotation of the clutch shaft 21 causes the chain 61 to be moved from the sprocket 59 fitted thereto to the sprocket 60 on the joint shaft 19.
When the clutch shaft 21 rotates once due to transmission, the connecting shaft 19 simultaneously rotates once.

Then, the knot cover 2 at the knot part 20
7, a guide rod 62 made of an elastic material such as a leaf spring is installed at a position near the tip of the grain culm, and the free end 62a of the guide rod 62 is inclined inwardly toward the exit of the grain culm passage passage 34. The discharging arm 38 is removably attached to the proximal end 62b with a bolt 63 so as to protrude from the base end 62b, and a grain culm support rod 64 made of an elastic material such as a leaf spring is also attached to the release arm 38 at a position near the tip of the grain culm. , the free end 6 of the grain culm support rod 64
4a intersects the free end 62a of the guide rod 62, and is detachably attached to the base end 64b with a bolt 65.

In this configuration, when the reaping and tying machine 1 moves forward, the grain culm that is pulled up by the grain culm pulling mechanism 14 and cut by the reaping mechanism 15 is moved to the door arm 3 by the swinging movement of the packer 35 in the tying device 16.
By repeating this process, the amount of focused grain culms on the front side of the door arm 37 increases, and when a predetermined amount is reached, the packer 35 moves the door arm 37 from the position of the solid line through the focused grain culms to the direction indicated by the arrow. 5
Since it rotates in the direction of 6, the clutch interlocking mechanism 57
As a result, the clutch gear 30 is turned ON, and the clutch shaft 21 begins one revolution.

By starting the rotation of the clutch shaft 21, the knot shaft 1
9 starts rotating at the same time, the discharge arm 38 starts rotating in the direction of the arrow 52 from the solid line position, and the needle 36 moves toward the knot 20, so that both ends of the string are removed by the bill 25 and the holder 26. Bind and then cut.

When this binding is completed, the door arm 37 will be connected to the arrow 57.
While rotating in the direction indicated by the two-dot chain line,
By rotating the discharge arm 38 back to its original position, the bundled grain culm bundle is discharged to the side. During the discharge by the discharge arm 38, the door arm 37 rotates to escape as shown by the two-dot chain line. Return from the position to the original position indicated by the solid line and rotate. In this case, since the door arm 37 is provided at a lower height position than the discharge arm 38, the grain culm bundle is returned to a position below the discharge arm 38 while the grain culm bundle is being discharged by the discharge arm 38. The stock base is caught in the opposite direction to the release direction of the release arm. As a result, the grain culm bundle is released in a sideways position so that the tip of the grain is separated from the aircraft body.

When converging the grain culms at the 37 door arms, the tips of the grain culms are attached to the guide rod 62.
It is pushed into the grain culm passage passage 34 by the guiding action of the grain culm passage passage 34 to prevent it from expanding in a direction perpendicular to the longitudinal direction of the grain culm passage passage 34, while being attached to the discharge arm 38 when converging grain culms. Grain culm support rod 6
4 is in a state where its free end 64a intersects with the free end 62a of the guide rod 62 to block the grain culm passing passage 34, so that the tip of the bundled grain culm is not pressed against the door arm 37 by the packer 35. This prevents the grain from falling in the direction of the exit of the grain culm passageway 34.

As a result, the tip of the bundled grain culm no longer expands and becomes approximately round, and binding is performed with the tip of the grain becoming approximately round. When tying is completed, the grain culm support rod 64 is When the discharge arm 38 to which this is attached rotates, it rotates to open the grain culm passing passage 34, so that the discharge of the bundled grain culms is not obstructed.

As described above, the gist of the present invention is the configuration described in the claims for utility model registration, and grain culms can be bound in a state where the tips of the grains are approximately rounded by the guide rod and the grain culm support rod. On the other hand, it has the effect of reliably preventing the door arm from operating unexpectedly.
