The left weeding rod 7c protrudes by S3 from the left end of the left crawler 3b, as shown in FIG. 8 when the left crawler 3b slides to the left. And

FIGS. 9 and 10 illustrate plan views of a field when a harvesting operation is performed in the field using the combine 1. FIG. In FIGS. 9 and 10, it is assumed that the field is rectangular and is surrounded by four linear side blocks B, and an uncut portion C indicated by oblique lines exists. The first harvesting operation is started from one corner of the field with the combine 1 getting into the position shown in FIG. At this time, since the cutting device 6 of the combine 1 is slid to the right, if the right weeding rod 7a is brought close to the shore block B and the cutting operation is performed without contacting the shore block B, the grain on the shore block B side is obtained. Weed the culm, but the right crawler 3a and the body frame 2
Does not come into contact with the shore block B.

[0025] In this way, the first reaping operation vegetates the culm on the side of the shore block B. However, since the right crawler 3a and the vehicle body frame 2 can perform the reaping operation without contacting the shore block B, the cutting operation can be performed. Not only does the stalk of the stalks remain uncut, but also in the case where obstacles protrude from the shore block, it is possible to prevent the right crawler 3a from colliding with an obstacle or to run the right crawler 3a on the shore block. Damage to the crawler.
In this state, the harvesting operation is continued by advancing upward in the figure of FIG. 9, and when reaching the upper end of the figure, the combine 1 is turned to the left, advances to the left in the figure, and similarly makes a round of the field counterclockwise. .

a, the right crawler 3a travels in the area after the first cut, and the left crawler 3b is driven by the left weeding rod 7a.
The vehicle travels on the field after cutting by the weeding of c. Turning left at the corner of the field and reaping counterclockwise is the same as the first time. After the third time, the harvesting operation can be performed in the same manner as the second time.

In this manner, in the second and subsequent harvesting operations, the left crawler 3b always runs on the field after the left weeding rod 7c has weeded and cut, and the grain stalk before cutting has not fallen down. In addition to being useful for mowing work in general fields, it is useful for cross-cutting where the culm rows are not aligned with the traveling direction of the combine 1 or the culm is not spread due to sowing. Even when used in a field with regular vegetation, the crawler 3 can cut the crop without causing the culm to fall down.

Since it is provided at a distance, even if muddy water or the like enters through the window-like opening 40c of the step, the starter terminal 20e is unlikely to be applied to the starter terminal 20e. Further, even when the toe of the shoe is put in step 40b, the starter terminal 20e does not come into contact with the shoe, so that the starter terminal is hardly damaged.

FIGS. 26 (a plan view of the combine 1) and FIGS. 27 (cutting) show an example in which the wiring harness of the combine 1 is easy to lay and maintenance such as inspection of the wiring harness and electrical check of the drive motor is extremely easy. This is shown in a partially cutaway perspective view from the right front of the combine 1 with the device 6 omitted.

In the combine 1, as shown in FIG. 26, a narrow guide 50 is provided on the left side of the combine 1 on the side opposite to the operator's seat 16, and a grain stalk standing on the left side of the left weeding rod 7c is left crawler. (Not shown), which acts on the left side so as not to be crushed, and is stored on the left side of the combine 1 at the time of storage. However, it is stretched to the position shown by the reference line in FIG. Can be put out.

The wiring harness 51 for controlling the operation of the conventional narrow guide 50 is directly wired from the battery 20b (FIG. 18) via the cable 20d, or is wired from the engine 20 together with the wiring harness 20k of the engine 20. In any case, when inspecting and maintaining the power supply section of the narrow guide 50, the troublesome work of rotating the Glen tank 13 (FIG. 17) and opening the seat cover and the engine radiator of the operation seat 16 is performed. 27, the power of the drive motor 52 (FIG. 29) of the narrow guide 50 is taken from the starter terminal 20e, and the fuse 52a of the wiring harness 51 of the narrow guide 50 is connected to the starter. Connect to terminal 20e.

In this way, the power supply connection portion of the wiring harness 51 of the narrow guide 50 can be easily visually recognized and easily accessed through the window-like opening 40c provided in the operation seat side cover 16c, so that the wiring harness 51 can be easily laid. In addition, maintenance such as inspection of the wiring harness 51 and electrical check of the drive motor 52 becomes extremely easy.

Next, a modified example of the combine 1 in which the safety of the electric circuit of the narrow guide 50 against overload is improved is shown in FIG.
(A plan view of the combine 1) and FIG. 28 (a side view of the operation seat 16).

The narrow guide 50 comprises a front bar 50a and a rear bar 50b. The front end of the front bar 50a is rotatably pin-joined to the left weeding rod 7c by a pin 50c. The rear end and the front end of the rear bar portion 50b are rotatably pin-joined by a pin 50d, and the sliding ring 50e at the rear end of the rear bar portion 50b is
A loosely fitted slide bar 2c (FIG. 31) is provided to allow the combine bar 1 to be slidable in the front-rear direction and slightly rotatable. A connecting pin 50f is provided near the front end of the rear bar 50b. It is connected to the drive actuator 53 so as not to deviate and rotate freely, so that the narrow guide 50 projects and is stored by expansion and contraction of the drive actuator 53.

Driving actuator 5 of narrow guide 50
3, a limit switch 53a for detecting a storage position and a maximum extension position of the narrow guide 50 is provided, and a battery cable 20d, a starter cable 20f and a starter terminal 20e as shown in FIG. A narrow guide wiring harness 51 is connected together with the engine harness 20k, and a drive motor 52 (FIG. 2) is connected between the wiring harness 51 and the starter terminal 20e.
Fuse box 52 to protect 9) from overload
a, and a fuse (not shown), a thermal relay 52c (FIG. 27) and a relay operated by the limit switch 53a are wired in series in the fuse box 52a.

As shown in FIG. 30, the drive actuator 53 of the narrow guide 50 is provided with a limit switch 5 for detecting the storage position and maximum extension position of the narrow guide 50.
When the narrow guide 50 reaches the storage position or the maximum overhang position, the limit switch 53a is provided.
Operates, the relay (not shown) in the fuse box 52a (FIG. 28) cuts off the current of the drive motor 52 and prevents the overload current from flowing, and the overload current flows through the drive motor 52 for some reason. Even in this case, first, the thermal relay 52c operates to protect the drive motor 52,
Further, the thermal relay 52c can be easily returned to operation after the temperature of the drive motor 52 has dropped, and even if the thermal relay 52c fails, a fuse (not shown) finally protects the drive motor 52. The drive motor 52 can be multiply protected, and the probability of fuse disconnection and replacement at the time of overload can be extremely reduced.

FIG. 29 (a perspective view from the left front with the cutting device 6 removed at the front of the combine 1) and FIG. 30 (a narrow guide driving mechanism) in which the extension and storage of the narrow guide 50 can be automated. (A perspective view showing details).

The narrow guide drive mechanism is connected to the other end of the narrow guide wiring harness 51 extending from the starter terminal 20e (FIG. 28), and is provided with a drive motor 52 fixed to the body frame 2 and the drive motor 52. A cable pulley 52e that rotates integrally with a worm gear that meshes with a worm screw fitted to an output shaft (not shown) of the motor 52; and a narrower when the drive motor 52 is wound around the cable pulley 52e and rotates toward the storage side of the narrow guide 50. A cable 52h for pulling the guide 50, and an air damper 53 rotatably and slidably connected in the direction of the long hole by a pin 53e having one end 53d inserted into a long hole 2b provided in a bracket 2a fixed to the body frame 2. And the air damper 53
Has a rod 53c which is always urged in the direction of extension by gas pressure contained in a bladder or the like, and a connection portion at the other end of the rod 53c is pin-connected to the narrow guide 50 together with a cable 52h by a pin 50f. Motor 5
2 rotates as described above, the cable 52h is pulled against the urging force of the air damper 53 to pull the narrow guide 50 toward the storage side, and the storage position is set by the operation of the cam plate 53b and the limit switch 53a in the storage position. When the drive motor 52 rotates to the opposite side, the rod 53c of the air damper 53 is extended by the urging force by the urging force, and the narrow guide is transmitted. In this configuration, the maximum extension position is detected by operating the cam plate 53b and the limit switch 53a at the maximum extension position, and the position signal of the narrow guide 50 is transmitted.

In addition to these, the rod 54c has the same shape as the air damper 53, and the rod 54c can freely expand and contract, but supports the reinforcing guide 54 having no damping action and urging force with the pins 50f and 53e, and expands and contracts with the air damper 53. To reinforce the air damper 53 and prevent the narrow guide 50 from bending.

In this example, the drive mechanism for extending and storing the narrow guide 50 is pulled by the drive motor 52,
Alternatively, since it is composed of the cable 52h to be fed out, the air damper 53 having the rod 53c constantly urged in the extension direction, and the limit switch 53a for detecting the maximum extension position and the storage position of the narrow guide 50, the operation seat 16 In addition to the extension and storage of the narrow guide 50 by remote control, if a control device not shown in detail is used, the extension and automatic storage can be performed automatically by the detection signal of the limit switch 53a. Since the operation is started and stopped by the detection signal of the limit switch 53a, the motor current does not become excessive, so that an extremely excellent effect that there is no disconnection of a fuse (not shown) can be obtained.

Since the air damper 53 always acts on the extension side, the support pin 53e always stays on the opposite side (motor 52 side) of the elongated hole 2b instead of the position of FIG. Slides to the left, the long hole 2b
To move to the opposite side of the motor. Further, since the worm gear is used in the narrow guide motor for deceleration in the narrow guide 50, the reaper 6 is fixed at the sliding position, and the air damper 53 absorbs the force acting on the narrow guide 50. .

FIGS. 31A and 31B are plan views showing a simplified structure of a drive mechanism of the narrow guide 50. FIG. (Partial perspective view of panel 17).

One end of the cable 55d is fixed to the rod 55b, and the rod 55b is pulled inward in the axial direction of the cylinder 55a. As shown in FIG. 32, the other end of the cable 55d is connected to the harvester operating culm 19e by a link mechanism. Connect via 56.

A mechanical actuator 55 having a rod 55b constantly urged outward by a compression spring 55c and a cutting device operating rod 19e are connected to an operating cable 55d.
Connected by When the harvester operating culm 19e is operated from the "off" position to "on" in order to drive the harvester 6, a not-shown harvester clutch is engaged to start the operation of the harvester 6, and the link mechanism 56 allows the cable to be operated by the link mechanism 56. 55d is loosened, the rod 55b projects by the urging force of the spring 55c, and presses the narrow guide 50 via the pin 50f to act to project the narrow guide 50.

When the mowing device operating culm 19e is operated to stop the mowing device 6, the mowing clutch is disconnected, the cable 55d is pulled, the rod 55b is pulled in against the urging force, and the rod 55b is pulled through the pin 50f. Since the narrow guide 50 is housed, not only the configuration of the drive device of the narrow guide 50 is simple, but also the operation of projecting and storing is simple, and the operation of the reaper 6 is reliably interlocked with the operation. This produces an effect that the user does not forget to store the narrow guide 50 by forgetting the operation.

A structure for simplifying the structure of the drive mechanism of the narrow guide 50 and operating lightly is shown in the side view of the operating seat in FIG. 33 and the front view of the operating seat in FIG. Show. The main part of the narrow guide 50 and the partially cutaway plan view of the mechanical actuator 55 are the same as FIG.
