BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a direction control device for a reaper.

[0002]

2. Description of the Related Art Conventionally, a weeding frame provided for weeding planted grain culms on a cut ground side of a mowing device, and a grain culm raising provided for raising weeding grain culms behind the weeding frame. There is a reaper having a configuration provided with a device. In addition, for example,
-55864 (Japanese Utility Model Application Laid-Open No. 58-158614), JP-A-60-168309, JP-A-50-151622, and JP-B-60-23802.
Patent Document 1: Japanese Patent Application Laid-Open Publication No. H10-205, as disclosed in Japanese Unexamined Patent Application Publication No. H11-284, a weeding frame provided for weeding the planted grain culm on the already cut ground side of the mowing device, and a grain culm raising provided for raising the weeding grain culm behind the weeding frame In the reaper provided with the device, the antennal of the direction sensor for cereal stem detection, provided in front or rear of the cereal stem raising device, further, the antennal of the direction sensor is weeded by the weeding frame. There is a direction control device for a reaper having a steering control device for steering the machine body to the uncut side when the cereal stem raised by the cereal stem raising device is not detected. This is to make effective use of the cutting width of the cutting device and prevent uncut cutting of the planted grain culm. In the state where the antennal of the direction sensor is detecting a grain culm, the body is maintained in a straight-ahead state.

[0003]

As described above, the steering control device according to the prior art is designed so that when the direction sensor for detecting the grain stalk provided on the already-cutted ground side of the reaper does not detect the grain stalk, the body of the steering control device is controlled. Is steered toward the uncut land side, thereby effectively utilizing the cutting width of the cutting device, and trying to prevent the uncut remaining of the planted grain culm.

[0004] However, in the above-mentioned prior art configuration, the antennal of the direction sensor for detecting the grain culm provided on the cut ground side of the reaper is only provided in front or rear of the grain culm raising device. In addition, there is no member for guiding and guiding the grain culm to the antennal, and no device for forcibly guiding the grain culm to the antennal is provided. For this reason, the culm, which is weeded by the weeding frame and raised by the cereal culm raising device, itself falls due to contact resistance with the antennal body, etc., and due to these causes, the antennal body removes the culm. In some cases, detection cannot be performed accurately. Then, even though the aircraft is in the proper traveling direction along the culm row, the aircraft is steered to the uncut area, and the aircraft is excessively steered to the uncut area, and eventually. However, there is a problem that uncut leaves and running of the grain stem by the traveling device are caused.

[0005]

The present invention employs the following technical means in order to solve the above-mentioned problems. That is, the reaper and minute grass frame 12 provided to Sosu the planting culms min in already calicivirus side of the apparatus 16, provided in order to cause a partial grass culms keep <br/> behind the該分grass frame 12 Grain raising device 13

The configuration is as follows.

[0006]

The operation and effect of the present invention will be described. In the cutting operation, the cutting machine is driven forward while the cutting device 16 is driven, and the culm to be planted in the field is mounted on the weeding frame 12.
The grass culm is raised by a cereal stem raising device 13, and the raised cereal stem is scraped and conveyed by a scraping device 14. Then, during or after the raking conveyance, the root portion of the cereal stem is cut by the cutting blade device and cut.

In such a mowing operation, the antennal 5 of the direction sensor A for detecting the grain culm is provided so as to face below the area where the squeezing device 14 squeezes in plan view. The grain stalk captured and rubbed and transported by the device 14 comes into contact with the antennal 5 of the direction sensor A. Thereby, the antennal body 5 of the direction sensor A can accurately detect the cereal culm during the scraping conveyance, and when the hull is in the proper traveling direction along the cereal culm row, the hull is moved to the uncut side. Therefore, it is possible to prevent occurrence of troubles such as uncut leaves and stepping down of the grain stem by the traveling device.

[0008] As a result, it is possible to carry out a smooth mowing run while properly maintaining the running state along the culm row.

[0009]

Next, an embodiment of the present invention will be described. In the illustrated example, the combine has a pair of left and right traveling devices 8 and 9 and is configured to be able to travel by being transmitted from an engine via a traveling transmission having a steering clutch. The left and right steering clutches are provided with electromagnetic solenoids 10 and 11, respectively.
By operating 0 and 11, the left or right steering clutch is turned on / off to perform steering control. A cutting device 16 including a weeding frame 12, a grain stalk raising device 13, a scraping device 14, a cutting blade device 15, and the like is provided in the front, and a grain stalk cut by the cutting device 16 is provided at a rear portion. A threshing device for transporting and supplying and threshing, a control device, an engine, a paddy storage device, and the like are provided.

Inside the weeding frame 12, a cereal stem raising device 13 is provided.
On the rear side, the antennas 5 and 6 are projected. The antennas 5 and 6 are disposed below the squeezing operation area of the squeezing belt 17 of the squeezing device 14. Further, the scraping device 14 may be constituted by a scraping belt 17 and a guide rod 18 opposed thereto. The front antennae 5 is protruded inward longer than the rear antennae 6, and is provided so as to be freely rotatable back and forth with the rotation position 2 being forward of the rotation position 3. It protrudes and stops at right angles, and is constantly urged forward by a spring. In addition, the angle of the tilt rotation toward the rear outside is set in a free range. At the turning positions 2 and 3, contactors 1 and 6 are rotated by a certain angle backward to contact points 1 and 2.
A pair of left and right direction sensors A and B for transmitting input signals to the steering control device 7 by turning ON the reference numerals 9 and 20 are formed.

Reference numeral 21 denotes an automatic steering control switch for switching the steering control device 7 to an automatic control state. When performing manual steering control, the automatic steering control switch 21 is turned off.

A vehicle speed sensor 22 detects the running speed of the body 1, and turns off the automatic control of the steering control device 7 when the vehicle is running at a high speed or when the vehicle is stopped. Reference numeral 23 denotes a grain stalk sensor, which detects the stalk by being guided to the reaping device 16 and turns on the automatic control of the steering control device 7;

The cutting is performed while the right weeding frame 12 provided with the antennal bodies 5 and 6 in the illustrated example is positioned outside the grain culm row 4 to be mowed and on the already cut culm side and is advanced. This weeding frame 12
Is guided by the cereal stem raising device 13 and further guided by the rear rake device 14. The antennal bodies 5 and 6 are slid from the outside to the base side of the cereal stem row 4 during the scraping action. If the mowing device 16 is too close to the left side of the culm row 4, the front and rear antennal bodies 5, 6 are both slidably in contact with the culm row 4 and tilted and rotated rearward, and the contact points 19, 20.
Is turned on, and is output to the right solenoid 11 by a pulse signal from the steering control device 7 to perform the right correction control C for disengaging the right steering clutch and changing the traveling direction to the right (third). Figure).

When the rear antennal 6 separates from the culm row 4 by the correction to the right side in this way, the left and right steering clutches are engaged and the neutral control D is performed, and the reaper 16 is controlled by the reaper 16. Proceeding straight from the row 4 in the oblique direction outward, the antennal bodies 5, 6 leave the culm row 4. At this time, the contacts 19 and 20 are turned off and the left steering clutch is disengaged by the left solenoid 10, and the left correction control E for correcting the traveling direction to the left is performed (FIG. 4).

While repeating such control, the cereal stalk row 4
Is performed along the straight line. As described above, by providing the antennas 5 and 6 below the scraping device 14, the antennas 5 and 6 are provided.
Since the culm 6 is brought into contact with the culm of the grain culm stretched to a certain posture, stable directional control can be maintained.
