When the guide rail 5 is arranged obliquely with respect to the longitudinal direction of the machine body below the endless rotating body 4 as shown in FIG. The position is changed in the longitudinal direction of the machine at the same time as the position is changed in the longitudinal direction of the machine.
Thus, if the end portion 5b of the guide rail 5 is expanded and contracted, the position where the exhaust straw A falls from the end of the guide rail 5 can be changed in the front-rear direction of the machine body, and at the same time, the lateral direction of the machine body (the culm of the Body direction). Thereby, if the terminal end portion 5b of the guide rail 5 is expanded and contracted, the position where the straw is supplied to the binding device can be adjusted in the direction of the stem. Then, when the set unity position set by the setting unit is artificially set so as to be a desired unity position and the straw is processed, even if the culm length of the grain stalk changes, the operation unit detects the change from the sensor. By automatically operating the actuator based on the cereal stem information to extend and retract the end portion of the guide rail, the position of supplying the straw to the binding device is adjusted. That is, adjustment is performed so that the binding position by the binding device becomes the binding position set by the setting means. This allows the binding device to perform the binding process at the set binding position while keeping the binding device fixed at an appropriate position even if the length of the waste straw changes.

Then, the waste straw A is supplied to the shredding device 2 or the binding device 3 in the state of the sideways posture.

Next, the waste straw A is cut into the shredding device 2 or the binding device 3.
The structure in which the waste straw A is supplied to the binding device 3 will be described. As shown in FIG. 1, the guide rail 5 has a solid rod-shaped end portion 5b slidably mounted inside a cylindrical start portion 5a. As shown in FIGS. 1 and 2, two wires, a first wire 8 and a second wire 9, are wound around a pulley 7 at another position, and the first wire 8 is connected to the end portion 5 b of the guide rail 5. The second wire 9 is connected to the distal end 5
b is connected to the base end side.

A motor 12 (corresponding to an actuator) and a reduction mechanism 10 are arranged adjacent to the pulley 7. The fan-shaped gear 11 is engaged with the drive gear 13 of the reduction mechanism 10 and the gear portion 7 a of the pulley 7. are doing. With this structure, when the driving gear 13 is rotationally driven by the motor 12 and the speed reduction mechanism 10, the fan-shaped gear 11 is driven to swing and the pulley 7 is rotationally driven. When the pulley 7 is rotationally driven in this manner, the first and second wires 8 and 9 are pushed and pulled, and the end portion 5b of the guide rail 5 is slid.

As shown in FIG. 1, a dial-type changeover switch 17 (corresponding to a setting means) is arranged on the control section of the fuselage.
Has been entered. A signal from a feedback potentiometer 18 provided on the sector gear 11 is also input to the control device 19. As a result, as described later, the slide operation of the end portion 5b of the guide rail 5 is performed by the changeover switch 17.

In the state shown in FIG.
This is a state in which the terminal end portion 5b of the guide rail 5 is extended to the maximum by operating to the first position. In this state, the binding device 3
When the binding door 14 and the string (not shown) are removed, the waste straw A transported to the end of the transport chain 4 is rotated by the rotary scraping arm 15 and the packer 16.
, And is discharged to the rear of the machine body without passing through the binding device 3 without being bound.

Next, a state in which the binding device 3 is operated will be described. In this state, the binding position of the waste straw A is set (the position of a few centimeters from the stock source), the actual length of the waste straw A is detected, and the predetermined position of the waste straw A is sent to the binding portion of the binding device 3. There are three sets of operations to perform. Waste straw A
Is set by setting the changeover switch 17 shown in FIG.
By manually switching to the positions A1, A2, A3, and A4 (the bundling position of the A1 position is closest to the base of the stock and the A4 position is farthest from the base of the stock), the bundling position of the waste straw A is changed to four. The position can be set, and the operation position of the changeover switch 17 is input to the control device 19.

As shown in FIG. 7, in the combine, the grain stalks cut by the cutting unit 20 are transferred to the feed chain 23 of the threshing device 1 via the locking and conveying device 21 and the sandwiching and conveying device 22. In this case, the locking and nipping transport devices 21 and 22 are integrally supported so as to be able to swing up and down around the horizontal axis P1 of the body, and a pair of head sensors 24 for detecting the position of the head on the grain culm are provided. In order for a predetermined position to be delivered to the feed chain 23 from the tip,
The angle of the locking and nipping transport devices 21 and 22 is changed up and down by the drive mechanism 25 (so-called handling depth control).

An angle sensor 26 for detecting the angles of the locking and nipping and conveying devices 21 and 22 at the position of the horizontal axis P1.
Is provided, and the angles of the locking and nipping transport devices 21 and 22 are input to the control device 19. In other words, the handling depth control
Based on information from the tip sensor 24, the locking and nipping / conveying devices 21 and 22 are swing-adjusted so that the tip length supplied to the handling room is constant even if the stem length of the grain stem changes. are doing. Thereby, the locking and nipping transport devices 21 and 22
By knowing the angle of the straw, the culm length of the whole harvested grain culm as grain culm information for adjusting the straw tying position, the length of the transported grain culm from the clamping position by the feed chain 23 to the stock root, the transport Each of the positions of the grain stem relative to the body of the stock can be detected. Therefore, the angle sensor 26 is
The angles of the locking and nipping and conveying devices 21 and 22 that are rocked and controlled as the handling depth control are input to the control device 19 instead of the culm length of the grain culm.

As shown in FIG. 4, the transport chain 4 and the guide rail 5 are arranged obliquely with respect to the longitudinal direction of the body. Therefore, if the position where the discharge straw A is separated from the transport chain 4 is changed by contracting the end side portion 5b of the guide rail 5 from the state shown in FIGS.
Can be changed in the direction of the stem of the straw A (lateral direction of the machine).

A stock tapping plate 27 (corresponding to a tapping aligning device) for tapping and aligning the stock of the straw A is provided on the stock side of the binding device 3. As shown in FIGS. 4 and 5, a guide frame 28 is erected and fixed in the vicinity of the binding device 3 along the lateral direction of the body.
A support portion 29 is slidably mounted along 8. Then, the base tapping plate 27 is swingably pivoted around the longitudinal axis P2 at the end of the frame 30 fixed to the support portion 29.
Is supported, and the motor 3 fixed to the support portion 29 is
1 and a batting plate 27 are connected via a link rod 32, and the batting plate 27 is driven to swing by a motor 31 so that the batting of the waste straw A is beaten.

As shown in FIG. 4, the frame 33 on the fuselage side
A screw shaft 34 is provided between the screw shaft 3 and the binding device 3.
4 is externally fitted with a screw structure. And the binding device 3
A motor 35 (corresponding to an actuator) that rotationally drives the screw shaft 34 is provided. The rotational movement of the screw shaft 34 by the motor 35 causes the support portion 29 and the batting plate 27 to move in the lateral direction of the machine. It is configured so that the position can be adjusted by sliding it.

With the above structure, as shown in FIG. 6, first, the changeover switch 17 shown in FIG. 1 is set to A1, A2, A3, A4.
The user operates the position to set the binding position (step S1).
Waste straw A detected by angle sensor 26 shown in FIG.
(Step S2) is longer than the first set length L1 (for example, 80 cm) and the second set length L2
If it is shorter than (for example, 100 cm), the process proceeds to step S9 without any particular limitation.

Accordingly, an operation signal is sent from the control device 19 to the motor 12 in FIG. 1 so that the binding process is performed at the binding position set by the changeover switch 17 based on the detection of the length of the waste straw A. Then, the terminal side portion 5b of the guide rail 5 is automatically extended and contracted (step S9). At the same time, based on the detection of the length of the waste straw A, the control device 19 sends an operation signal to the motor 35 shown in FIG. Then, the position of the tapping plate 27 is automatically adjusted (step S11) (corresponding to the operation means). In this case, at the A1 position where the unity position is closest to the stock base,
At the A4 position where the base tapping plate 27 is closest to the binding device 3 side and the binding position is farthest from the source, the base tapping plate 27 is farthest from the binding device 3.

As shown in FIG. 7, a contact type presence / absence sensor 40 for detecting the presence / absence of a grain culm is provided at a front portion of the locking / conveying device 21. If the presence / absence of the grain stem is detected by the presence / absence sensor 40, the process proceeds from step S10 to step S11 as shown in FIG. 6, and the position of the batting plate 27 is automatically adjusted. Conversely, if the presence of a cereal stem is not detected, the process proceeds from step S10 to step S1.
In step 2, the beating plate 27 is operated to a position farthest from the binding device 3 (downward in FIG. 4).

The above state is a case where the length of the waste straw A is within a normal range. In the above-described handling depth control, an operation is performed such that a predetermined position from the tip is delivered to the feed chain 23 shown in FIG. 7. Therefore, when the waste straw A is delivered from the feed chain 23 to the transport chain 4, If the cereal stem is long, the stock of the straw A protrudes greatly from the transport chain 4 downward in the drawing of FIG. Conversely, if the grain culm is short, the stock of the straw A will be very close to the transport chain 4.

Therefore, as shown in FIG. 6, when the length of the waste straw A is equal to or less than the first set length L1 (for example, 80 cm) (step S3), the set binding position is A1.
If not, the binding position is A1 (the position closest to the stock company)
(Steps S7 and S8). This is because if the binding position is set to a position away from the base of the stock while the stirrer A is too short, the end portion 5b of the guide rail 5 is contracted, and the stirrer A supplied to the bundling device 3 is operated. Position of Fig. 4
This is to prevent a situation in which the binding position is too close to the spike side due to being too low in the drawing.

Conversely, as shown in FIG. 6, when the length of the waste straw A is equal to or longer than the second set length L2 (for example, 100 cm) (steps S3 and S4), the set binding position is changed. If A1, the binding position is A2 (A1 closest to the stock
From the position, the position is changed to one position away from the stock company (steps S5 and S6) (corresponding to a change unit).

If the binding position is set to a position close to the base of the stock while the waste straw A is too long, the waste straw A is bound even if the end portion 5b of the guide rail 5 is extended to the stroke end. In the case where the base of the waste straw A is excessively protruded downward from the bundling device 3 in FIG. 4 when supplied to the device 3, that is, the end portion 5 b of the guide rail 5 is extended to the stroke end. Also, a state occurs in which the binding position of the waste straw A is located on the tip side of the position corresponding to the position A1. In such a case, if the position of the batting plate 27 is operated to a position closest to the binding device 3 corresponding to the position A1, the batting plate 27 of the above-mentioned greatly protruding straw A is placed on the batting plate 27. The original may be pressed and clogging may occur at this point.

Therefore, in such a case (when the length of the waste straw A is equal to or longer than the second set length L2), the binding position set at the position A1 is automatically changed to the position A2. By doing so, the position of the tapping plate 27 can be adjusted by the binding device 3.
Is operated from the position corresponding to the position A1 closest to the position A2 to the position corresponding to the position A2 remote from the binding device 3. As a result, the space between the binding device 3 and the batting plate 27 is increased, so that the clogging at the batting plate 27 as described above can be prevented.

Next, a state in which the waste straw A is fed into the shredding device 2 will be described. As shown in FIGS. 1 and 4, on the upper side of the shredding device 2, there is provided a cover 37 which can be opened and closed around a horizontal axis P3 and is urged to the closing side by a spring 36. The cover 37 is in the closed state when the switch 17 is being operated to the A1 to A4 positions. FIG.
As shown in FIG. 3, a guide groove 7 b is provided on the lateral side surface of the pulley 7 over the entire circumference, and a downward projection 38 a is provided.
Is fitted in the guide groove 7 b, and a third wire 39 is connected between the operation member 38 and the cover 37.

As shown in FIGS. 1 and 3, the guide rail 5
When the end portion 5b is fully extended (the changeover switch 17 is operated to the position A1), the projection 7c in the guide groove 7b is located on the right side of the projection 38a of the operation member 38 in the drawing. From this state, the changeover switch 17 is set to A2, A3,
Even if the binding position is changed by operating to the A4 position, only the pulley 7 is rotated clockwise (within 360 degrees) on the drawing sheet, so that the operating member 38 remains at the position of FIG. Also maintain the closed state.

When the changeover switch 17 is operated to the position B, the pulley 7 is rotated clockwise by about 360 degrees from the state shown in FIGS. In such a state, the trailing end portion 5b of the guide rail 5 is slid to the most contracted state. Then, the projection 7c of the pulley 7 comes into contact with the projection 38a of the operation member 38 from the left side in the drawing, and the operation member 38 and the third wire 39 are pulled toward the pulley 7 to open the cover 37. Thereby, the waste straw A falls into the shredding device 2 from the middle of the transport chain 4 and is shredded.

[Another Example] FIG. 8 shows a waste straw processing structure having another embodiment.
A pair of left and right contact-type stock sensors 41 are fixed to the frame 30 supporting the stock tapping plate 27, and the stock of the straw A is positioned between the left and right stock sensors 41.
The screw shaft 34 is rotationally driven by the motor 35, and the stock sensor 41, the frame 30, the support portion 29, and the stock beater 2
The position 7 is slid left and right. That is, the position of the waste straw, which is conveyed to be supplied to the binding device 3 from the threshing feed chain 23 to the binding device 3 with respect to the machine body, is detected by the pair of stock sensors 41, 41, and based on the detection result, The movement of the batting plate 27 is controlled so that the batting plate 27 acts on the bait of the straw even if the height of the culm of the baling straw changes. At the same time, stock sensor 41
Is input to the control device 19 shown in FIG. 1 instead of the angle sensor 26. The control device 19 automatically operates the motor 12 based on the information from the stock sensor 41 and the set binding position set by the changeover switch 17 to extend and contract the end portion 5b of the guide rail 5. Thereby, the supply position of the waste straw to the binding device 3 is adjusted. That is, the discharge straw supply position is adjusted so that the binding position of the discharge straw by the binding device 3 from the stock source becomes the binding position set by the changeover switch 17.
