It is a pre-cutting device. In the pre-cutting device 5, the base (upper portion) of the longitudinal support frame 6 in the front-rear direction is rotatably attached to the body side, and the pre-cutting device frame 8 is attached to the tip of the vertical support frame 6. A cutting vertical cylinder 9 is provided between the cutting pre-processing device frame 8 and the machine body frame 1 to move the cutting pre-processing device 5 up and down. Pre-cutting equipment 5
In the foremost part of the herbaceous body 10 is provided, in the rear of each herbaceous body 10 is provided a raising device 11 for raising the weeded culm, and in the rear of the raising device 11, a star wheel 12 is provided.
A scraping device 13 is provided above the star wheel 12, and a cutting blade 14 is provided below the star wheel 12. 15a is a left stock side transfer device, 15b is a center stock side transfer device, 15
c is a right stock side transfer device, 16a is a left spike side transfer device, 16b is a center spike side transfer device, 16c is a right spike side transfer device.
To join.

The starting end of the adjusting stock transfer device 18 of the handling depth adjusting device 17 faces the junction A, and the ending portion of the adjusting stock transfer device 18 supplies grain culms to the threshing device 3. When facing the lower part of the starting end of the stock-side transfer device 25 to be transferred to the grain supply and transfer device 19, the handling depth adjusting device 17 determines the position at which the grain stalk is transferred to the stock-side transfer device 25 by changing the position of the grain culm. It changes to the culm direction, and adjusts the handling depth when supplying to the threshing room of the threshing device 3. The adjusting stock transfer device 18 of the handling depth adjusting device 17 is configured to have a transfer chain 26 and a clamping rod (not shown), and the transfer chain 26 is a frame (not shown).
And the end portion of the frame is moved to a position close to the stock-side transfer device 25 by an actuator 27 provided on the vertical support frame 6 side.

[0008] The end of the right-hand side transfer device 16c extends to a position above the stock-side transfer device 25, and the end of the stock-side transfer device 25 is configured to also serve as a transfer-head transfer device. But this is not a requirement. Further, the stock transfer side transfer device 25 includes a transfer transfer chain 30 and a transfer clamping rod 3.
1. The take-over transport chain 30 is wrapped around the drive gear 32 and the guide roller 33, and the guide roller 33 allows the perspective position to be freely changeable with respect to the start end of the grain culm supply transport device 19. That is, the guide roller 33 is mounted on the chain guide rail 34, the base of the chain guide rail 34 is rotatably mounted on the support frame 35, and an actuator 36 is provided between any fixed portion and the support frame 35. The grain culm supply / transportation device 19 is of a known configuration, in which a feed chain 39 is wrapped around a chain guide rail in the front-rear direction, and a clamping rod 40 is provided above the feed chain 39. It is provided on the upper cover 41 of the device 3.

[0009] Between the starting end of the feed chain 39 and the end of the stock-side transfer device 25, there is an auxiliary supply device 45 for feeding all the short culms into the threshing room of the threshing device 3. A culm input chain 46 is provided. The auxiliary supply device 45 is for supplying the short grain culm cut by ridge control described later to the threshing room of the threshing device 3. In other words, when the short culm is cut and supplied, the stock-side transfer device 25 changes its position to the deep-handling position, and the 30 thirty-four guide rollers 33 retreat with respect to the cereal culm supply / transport device 19. Thus, the root of the short culm is not supplied to the cereal culm supply / transport device 19, but is supplied to the entire culm by the auxiliary supply device 45. Thus, the pre-cutting device 5 is provided with a cereal stalk sensor 50 for detecting cereals in the field and a short culm identification sensor 51 for detecting the length of the cereals, respectively. A cutting height sensor 52 for detecting the height of the cutting is provided. The cutting height sensor 52 is constituted by a potentiometer, an ultrasonic sensor or the like.

When the pre-cutting device 5 has been raised to a predetermined height by the cutting height sensor 52 at a desired position of the control section, the threshing device 3 is driven. A cutting / transfer stop control ON / OFF switch 55 for turning on / off the cutting / transporting stop means (cutting / stopping control in the figure) for stopping the driving of the conveying device 19 is provided. In addition, as the pre-cutting device 5 approaches the ridge, the pre-cutting device 5 is gradually raised to cut the head side of the grain stalk, and the stock-side transfer device 25 is moved to the desired position of the control section. The position is changed to the handling position, and 25 thirty guide rollers 33 are retracted with respect to the cereal culm supply and transport device 19, and the root of the cut short culm is not supplied to the cereal culm supply and transport device 19, but is supplementarily supplied. A high-cutting control switch 56 for turning on and off the high-cutting control means (row control in the figure) for feeding all culms by the device 45 is provided. Then
Since the mowing transport stop control and the high mowing control are in a contradictory relationship, the mowing transport control is executed in preference to the mowing transport stop control, and the mowing pre-processing device 5 is raised to a stop height. The mowing pre-processing device 5 is also configured not to stop. That is, during the high-cutting control by the high-cutting control switch 56, the cutting pre-processing device 5 and the grain culm supply / transport device 19 are not stopped even if the cutting / transporting stop control ON / OFF switch 55 is ON and the cutting / transporting stop control is being performed.

FIG. 8 shows another embodiment of the control.
When both the cutting / transporting stop control ON / OFF switch 55 and the high cutting control switch 56 are ON and a predetermined time has elapsed since the grain culm sensor 50 was turned off, the cutting pretreatment device 5 and the grain culm supply / transport device 19 are stopped. The configuration is as follows. In other words, the grain culm sensor 50 is turned off when the ridge cutting is completed, but the cereal culm sensor 50 may be turned off even before the ridge cutting is completed. , The timing of the mowing transport stop control is set. Therefore, if the time required for mowing at the ridge is set to the predetermined time, the supply of the grain stalk can be reliably performed. in this case,
The timing of the mowing transport stop control is such that an off-delay is provided in the grain stalk sensor 50 to delay the operation based on the signal from the grain stalk sensor 50.

FIG. 9 and FIG. 10 show another embodiment of the control. When the grain culm sensor 50 is turned off, the cutting pre-processing device 5 is automatically stopped by the cutting and conveying stop control. When the automatic lift control on / off switch 60 is turned on, the cutting / conveying stop control on / off switch 55 and the high cutting control switch 56 are turned on, the grain culm sensor 50 is turned off. When the vehicle has traveled for a predetermined distance from, the cutting and conveying stop control is performed assuming that the ridge cutting has ended, and the cutting pretreatment device 5 and the grain stalk supply and conveying device 19 are stopped. Also, FIG.
This is another embodiment of the control, in which an off-delay is provided in the grain stalk sensor 50, and when a predetermined time has elapsed since the grain stalk sensor 50 was turned off, automatic lift control is performed. That is, at the time of the start of the high mowing control, the grain stalk sensor 50 may be turned off due to high mowing. Therefore, instead of performing the automatic lift control immediately after the grain stalk sensor 50 is turned off, the grain stalk sensor 50 is temporarily turned off. When the culm sensor 50 is turned on, high cutting control is performed,
When a high cutting control is ensured and a predetermined time has elapsed since the grain culm sensor 50 was turned off, it is considered that the ridge cutting is not performed, and the automatic lift control is performed.

FIGS. 12 and 13 show another embodiment of the control, in which when the culm sensor 50 is turned off and the vehicle travels a predetermined distance, the automatic lift control is performed. That is, at the time of the start of the high cutting control, the grain stalk sensor 50 may be turned off due to the high cutting.
Rather than performing auto-lift control immediately after 0 is turned off, it is assumed that it is not ridge cutting by running for a predetermined distance, and auto-lift control is performed, and the cereal stem once turned off before running for a predetermined distance When the sensor 50 is turned on, the automatic lift control is invalidated. FIGS. 14 and 15 show another embodiment of the control, in which the auto-lift control ON / OFF switch 60 during the high-cutting control by the high-cutting control switch 56.
When the automatic lift control is turned off, the automatic lift control is stopped, so that the cutting pretreatment device 5 is reliably prevented from ascending during the high mowing control. Reference numeral 70 denotes a stock sensor of the handling depth sensor, and reference numeral 71 denotes a tip side sensor of the handling depth sensor 33.

[0014]

Next, the operation will be described. When the airframe is advanced by the traveling device 2, weeding is performed by each weeding body 10, and the cereal culm weeded by the weeding body 10 is raised by the raising device 11, and is scraped backward by the star wheel 12, and the cereal culm is removed. , A left stock source side transport device 15a, a central stock source side transport device 15b,
The right stock source side transfer device 15c and the left spike side transfer device 16
a, the center tip side transfer device 16b, and the right tip end transfer device 16c, respectively, are cut by the cutting blade 14 during the transfer, and the transferred grain culms join at the junction A. The stem side of the grain culm that has joined the junction A is clamped by the adjusting stem conveying device 18 of the handling depth adjusting device 17, and the ear is conveyed by the right spike side conveying device 16c. The cultivars are transferred to the stock-side transfer device 25 and the cereal culm is transferred to the cereal culm supply and transfer device 19 by the stock-side transfer device 25.

In this case, the adjusting stock transfer device 1 of the handling depth adjusting device 17 is moved to the starting end of the stock transfer handover device 25.
8 can be adjusted in the direction of the culm of the cereal stem, so that the position of the end of the adjusting stock transfer device 18 is adjusted by the signals of the stock sensor 70 and the tip sensor 71. The clamping position of the culm is changed so that the handling depth of the culm supplied to the threshing room is adjusted to be substantially constant. That is,
The handling depth adjusting operation mechanism of the handling depth adjusting device 17 is such that the transport chain 26 is attached to the frame, the end of the frame is rotated by the actuator 27, and the end portion of the adjusting stock transport device 18 and the stock base side transfer device. The take-up point with the starting end of 25 is changed to adjust the handling depth.

In the field, when the pre-cutting device 5 is raised for the direction change, the cutting height sensor 52 detects this and the driving of the threshing device 3 is continued.
Automatically the pre-cutting device 5 and the grain culm supply / transport device 19
To stop driving. In this case, the cutting conveyance is stopped by turning on the cutting conveyance stop control on / off switch 55, but not executed by cutting off. Thus, when changing the direction, it is necessary to cut the grain culm at the ridge before the change of direction, but at the ridge, to prevent the pre-cutting device 5 from contacting the ridge, High cutting is performed to cut the tip side. Therefore, if the pre-cutting device 5 is raised with the cutting / conveying stop control on / off switch 55 turned on, the pre-cutting device 5 and the grain stalk supply / conveying device 19 are stopped, so that high cutting is performed at the ridge. At this time, high cutting control (ridge control) is performed by the high cutting control switch 56, and when both the high cutting control switch 56 and the cutting conveyance stop control ON / OFF switch 55 are ON, the high cutting control is preferentially executed. .

In the high cutting control, the pre-cutting device 5 is moved up to cut the tip side of the culm in the field, and the left-side stock transfer device 15a, the central stock-side transfer device 15b, and the right stock Side transfer device 15c, left tip side transfer device 16a,
Central tip side transfer device 16b, right tip side transfer device 16
The short culm is conveyed by each of c. Then, the grain culm sensor 50 is turned on by the grain culm being transported, but since the tip of the short grain culm does not contact the short grain culm identification sensor 51, the control unit recognizes that the short grain culm is being harvested and transported. So
The end of the adjusting stock transfer device 18 of the handling depth adjusting device 17 is moved away from the stock takeover transfer device 25 to the deep handling position, and then the end of the stock transfer device 25 is connected to the actuator. By 36, the grain stem supply / conveyance device 19 is retreated far away from the start end. Since the whole culm feeding chain 46 of the auxiliary feeding device 45 is juxtaposed at the start end of the cereal culm supply / transportation device 19, the root of the short culm culm is transferred from the stock origin side transfer conveyance device 25 to the whole culm feeding chain 25. Since it is taken over by 46 and is not pinched by the cereal culm supply / transportation device 19, the whole cereal culm is directly introduced into the threshing room.

That is, the short-grain culm is transferred to the control stock transfer device 18.
As a result, it is possible to take over all the spikes with grains to the stock-side handover / carrying-off device 25. Further, since all the culms are thrown in, the loss of unhandled stock is prevented.
When the high mowing on the ridge ends, the culm sensor 50
Is turned off, the cutting / transporting stop means is executed, and while the driving of the threshing device 3 is continued, the driving of the pre-cutting device 5 and the grain culm supply / conveying device 19 is stopped to change the direction. Next, when the direction change is completed, the pre-cutting device 5
Is returned to the predetermined cutting height, so that the cutting and conveying control of the cutting and conveying stopping means is stopped, and the cutting and threshing operation is restarted. Also,
In the embodiment shown in FIG.
And when both the high cutting control switch 56 is on, the cutting pre-processing device 5 and the grain culm supply / transport device 19 are stopped when a predetermined time has elapsed since the cereal stalk sensor 50 was turned off. Grain stalk sensor 50 during row cutting
Is turned off, the high mowing control can be completed without the mowing transport stop control.

In this case, since the predetermined time is set to a time required for cutting on the ridge after raising the pre-cutting device 5, the high cutting on the ridge can be surely performed. Further, the timing of switching to the mowing conveyance stop control is provided with an off-delay in the grain stalk sensor 50, so that the configuration can be simplified and the cost does not increase. Further, in the embodiment of FIGS. 9 and 10, when the culm sensor 50 is turned off, the cereal culm in the field is turned off to facilitate turning out of the culm group in the field during traveling for cutting and threshing work. Automatic lift control for recognizing that it has come out of the group and automatically raising the pre-cutting device 5 so that the cut-and-convey stop control is performed as the pre-cutting device 5 is raised. When the automatic lift control on / off switch 60 is on, the cutting / conveying stop control on / off switch 55 and the high mowing control switch 56 are on, and when the culm sensor 50 is off for a predetermined distance, the ridge is Since the harvesting and conveyance stop control is performed assuming that the mowing is completed, the cutting pre-processing device 5 and the cereal culm supply and transport device 19 are stopped by traveling a predetermined distance after the grain culm sensor 50 is turned off. Therefore, the grain stalk sensor 5
The high mowing on the ridge is completed during traveling a predetermined distance after 0 is turned off, and the operation for shifting to the next direction change is omitted, thereby improving the operability.

In the embodiment shown in FIG.
0 is provided with an off-delay, and when a predetermined time has elapsed since the culm sensor 50 was turned off, the automatic lift control is performed. Therefore, at the start of high cutting control, the culm sensor 50 is turned off for high cutting. Even if the stalk sensor 50 is turned off, the automatic lift control is not performed immediately after the stalk sensor 50 is turned off, but once the stalk stalk sensor 50 that has been turned off is turned on, the high cutting control is secured as the high cutting control. Then, when a predetermined time has elapsed since the grain stalk sensor 50 was turned off, it is considered that the ridge cutting is not performed, and the automatic lift control is performed. ,
Improve operability. In addition, in the embodiments of FIGS. 12 and 13, when the culm sensor 50 is turned off and the vehicle travels a predetermined distance, the automatic lift control is performed.
At the start of the high mowing control, the culm sensor 50 for high mowing is used.
When the grain stalk sensor 50 is turned off and the grain stalk sensor 50 is turned off, the auto-lift control is not performed immediately after the grain stalk sensor 50 is turned off. Can be secured, and then the grain stalk sensor 50
Since the automatic lift control is performed by running a predetermined distance after turning off the vehicle, it is considered that the cutting is not the ridge cutting, the operability is improved without interrupting the high cutting at the ridge.

In the embodiment shown in FIGS. 14 and 15, if the auto-lift control is turned off by the auto-lift control on / off switch 60 during the high-cutting control by the high-cutting control switch 56, the auto-lift control is stopped. Even if there is a defect in the grain stalk sensor 50 or the like, it is possible to reliably avoid raising the pre-cutting device 5 during high cutting control,
High mowing on the ridge can be performed.
