Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a straw bundling device equipped with a combine, for example, for binding the threshed straw in the threshing section.

[0002]

2. Description of the Related Art Conventionally, as disclosed in Japanese Utility Model Publication No. 49-31665, there is a technique in which a straw bundling machine and a stock gathering plate are integrally movable and adjustable.

[0003]

In the prior art, since the distance between the straw bundling machine and the stock yuan aligning plate is constant, the stock is adjusted according to the stock base of the straw fed through the straw chain. When the original alignment plate is adjusted, the binding position is inevitably determined, and there is a problem that the binding is not always performed at an appropriate position. For that reason, it is necessary to adjust the position of the stock aligning plate and the binding position of the straw binding machine separately, but when the stock aligning plate and the straw binding machine are moved separately, they contact each other. There was a problem such as damage. Also, the actual development 6
As shown in Japanese Patent Publication No. 0-67044, swinging in the longitudinal direction of the straw culm
The sensor rod is brought into contact with the stock gathering plate, and the stock gathering plate
There was also a technology to prevent people from approaching the binding machine, but
Since the movement of the plates is mechanically stopped,
There is a problem that it may repeatedly come into contact with the sir rod, causing damage and deformation.
And adjusting the fulcrum position of the stock alignment plate
It cannot be done on the way, so if the straw culm length changes on the way,
Durability such as having to suspend work and adjust the fulcrum position
And there was a problem in handling operation.

[0004]

Therefore, the present invention is intended for threshing.
Straws discharged from the section Adjust the movement of the binding machine in the longitudinal direction
A bundling position moving member is provided to freely change the bundling position of the bundling machine.
In the straw bundling device configured in the
Automatically move stock source plate based on the detection result of the original sensor
The aligning position moving member for adjustment is provided, and the binding machine and stock
Install a switch to detect the approach of the alignment plate,
The alignment position moving member operation in the direction in which the original alignment plate approaches is described above.
Provide a controller that limits by switch,
After the switch turns on, the stock sensor output changes.
It is configured to maintain the stock rectifying plate at a substantially constant position.
Therefore, a stock sensor is provided to automatically adjust the stock alignment plate position.
Since it is done in a continuous manner, the work is done continuously
The action can be maintained properly, and the binding machine and
Alignment position movement until stock origin sensor output changes even when approaching
Since the member operation is not performed, the binding machine is separated from the stock gathering plate.
The alignment position moving member is activated by
A haunch that can be blocked by the limitation of movement of the alignment position moving member
It is possible to easily reduce the handling operation and improve the handling operability.
In addition, it is possible to easily improve the stock yuan matching function .

[Table 1]

That is, when the aligning plate (35) is located at the leftmost end (longest culm position) and the left limit switch (63) is turned off, it serves as a reference point for adjusting the position of the aligning plate (35). The rotation sensor (67) starts the detection of rotation, and the rotation sensor (58) first detects the rotation.
At the longest culm where all the sensors (59) are turned on, the rotation of the motor (44) is kept at 0 to maintain the aligning plate (35) at the reference point position, and then the straw sensor (58) is operated. Two
When the sensor (60) or the third sensor (61) or the fourth sensor (62) is turned on, the motor (44) is sequentially rotated three times or six times so as to move the aligning plate (35) to the right. It is driven to rotate 9 times, and the first to fourth sensors (5

The first sensor at the rightmost position from the straw sensor (58). When all the elements up to (59) are on, the motor (44) is stopped to hold the alignment plate (35) at the reference point position, and the first sensor (59) to the fourth sensor (62) are sequentially turned off. At this time, the motor (44) is driven to rotate right by a set number of revolutions (3, 6, 9, 12 revolutions) according to the detection of each sensor (59) (60) (61) (62), and the aligning plate (35). To the right. During this work, the culm length of straw changed and
~ 4 When the detection values of the sensors (59) to (62) are changed, the aligning plate (3) stored in the control circuit (73).
5) Current position rotation speed (NB) and first to fourth sensors (5
9) to (62), the number of rotations (N
A) is compared, and the motor (44) is driven to rotate right or left by the number of rotations corresponding to the difference, and the aligning plate (35) is moved and adjusted to the right or left from the current position.

Further, when such an in-work straw sensor (58) is turned off and no straw is detected, as shown in FIG.
The motor (4

Further, during work, the aligning plate (35) moves to the right, the auxiliary deck ( 37 ) contacts the right limit switch (64), and the switch (64) is turned off. When this occurs, as shown in FIG. 11, the right rotation of the motor (44) is stopped, and 200 m seconds after the stop, the motor (44) is rotated left one rotation and then stopped. As long as there is no change in the detection of the sensors (59) to (62), this position is maintained, and hunting of the alignment plate (35) control based on the deviation between the adjusted position and the actual position is prevented . Discharged from the threshing section (6)

After turning on, the first to fourth sensors (59) to (6
2) Hold the stock leveling plate (35) at a fixed position until the output changes.
It is configured to be kept in place.

When the detection of the sensors (59) to (62) changes when the motor (44) is stopped at the position of the right limit switch (64), control is performed based on the detection signals of the sensors (59) to (62). As shown in FIG. 12, the alignment plate (35) is moved to the right by the detection signal of the fourth sensor (62), the right limit switch (64) is turned off, and the motor (44) is turned on. After turning one turn to the left and stopping, the third
When the sensor (61) is turned on, after 500 msec, the motor (44) is rotated to the left two times (the position where the motor is rotated six times to the right with respect to the reference point) to change the position of the aligning plate (35).

On the other hand, while the alignment plate (35) is being automatically controlled by the sensors (59) to (62), the manual switch (76) is used.
As shown in FIG. 13, when the manual switch (76) is rotated clockwise while the motor (44) is rotating clockwise based on the detection of the third sensor (61), the switch (76) is operated.
