Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to an automatic travel direction control device in a vehicle.

(Prior Art) Some known combine harvesters are equipped with an automatic running direction control device that automatically performs row alignment.

This conventional device detects the direction of the rice row using a grain culm position sensor attached to the dividing rod, and if the rice row curves to the right as shown in Figure 2, it automatically steers the combine harvester in accordance with the curve. (Problem to be solved by the invention) However, the reaping work of a combine harvester can only be done in the vertical direction (planting direction) with respect to the rice rows. Instead, there are times when the rice rows are harvested horizontally, like circular harvesting.

In this case, when rice rows are planted in three rows, for example, three adjacent rows may be slightly shifted in the lateral direction as shown in FIG. There are two types of deviation: large deviations and small deviations.In other words, if the combine is moved forward, there will be uncut material and the direction of the combine must be adjusted, or if the combine is allowed to move forward. There is no need to adjust the direction of the con/in because there is no uncut mowing.

However, even if the combine harvester continues to move forward, there will be no uncut material, so even if there is no need to change the direction of the combine harvester to A, if the automatic travel direction control device is used to automatically reap the harvest, the machine will automatically adjust to the left and right. Not preferred 1゜ (Means for solving the problem) Therefore, the present invention provides a grain culm position detection sensor 2 on the dividing rod 1 provided in front of the combine harvester, and uses the signal detected by the sensor 2 to detect the input of the combine harvester. In the apparatus in which the row alignment of the weeding rod 1 is automatically performed by automatically controlling the left and right crawlers of the cropping rod 1, the signal from the sensor 2 is determined so that the grain culm position is on the left side with respect to the weeding rod 1. r when it deviates by more than the value
"NJ No. 6 and grain culm position 8 have shifted to the right side by more than the specified value" of "1" to "14" indicating a deviation between the LJ signal and the grain culm position to the extent that no uncut material will be left even if the combine moves forward. If the signal for the first grain culm of a different planting row is "NJ" when the combine harvester cuts laterally to the rice row, the automatic control This is a configuration of an automatic travel direction control device in a combine harvester configured so that the device is not operated.

One embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a dividing rod installed in front of the combine harvester, and the dividing rod 1 is provided with a sensor 2 for detecting a shift in the position of rice rows. . The sensor 2 uses a bar sensor that detects the grain culm by contacting it or a non-contact sensor that detects the grain culm using a detection wave. 3 is an A/D converter which outputs the position of the grain culm detected by the sensor 2 as a digital signal as shown in FIG. That is, the "L" signal indicates that the grain culm position has deviated to the left with respect to the dividing rod 1 by more than a specified value, and the direction of the combine must be corrected to the left, and the "N" signal indicates that the grain culm position has shifted to the left. The rRJ signal indicates that the grain culm position has shifted to the right by more than a specified value, and is composed of signals ``1'' to ``14'' that indicate a deviation that does not leave any uncut material even if the combine moves forward.
Indicates the deviation that requires correcting the direction of the combine to the right, 4 is the central processing unit, 5 is the output interface, 6 is the right llenoid that disengages the clutch of the right crawler of the combine, 7 is the clutch of the left crawler of the combine 8 is the left solenoid that cuts off the row number, and 8 is the row number manual switch that inputs the number of rows to be planted in that field.

(effect) Next, we will discuss the effect.

A combine harvester is placed in a field, and the number of rows planted in the field is set to, for example, ``3'' rows, and the number of rows is entered using a cutter inch 8, and the weeding rod 1 is turned around to match the grain culm and mowed.

When the first vertical reaping operation is completed, the combine is rotated to the left, for example, and run to the left.
When the first row contacts the sensor 2, the position of the grain culm is detected by the sensor 2, and this signal is input to the A/D converter 3, and as shown in FIG. ``LJ double signal'' when the grain culm position deviates to the left by more than a specified value ``N'' signal of ``1j to ``14'' indicating a deviation to the extent that no uncut material is left even if the combine moves forward "R" when the culm position shifts to the right by more than the specified value
Output one of the signals.

At this time, for example, if a signal of "3" is output, this is a signal when the grain culm is slightly shifted to the left, but since it is an "N" signal as a whole, it is difficult to determine which row of the grain culm it is. subject to judgment. However, this grain culm is the first row,
Since it is not the first grain culm at the joint between the planting rows (3N+1st grain culm, where 3 is the number of planting rows and N is a natural number), the left solenoid 7 is turned ON, and the left crawler is turned on. −
is paused and the direction of the combine is controlled to the left.

When the sensor 2 comes into contact with the fourth grain culm, that is, the first grain culm in the seam, and the A/D converter 3 outputs a signal of "3" in the same manner as above, this signal is "N". ”
Because it is a signal.

Even though it is slightly off to the left, it continues to move forward without any direction control and reaps the grain culm.

Further, in each of the above cases, if the output from the A/D converter 3 is rR'' or rlJ, direction control is performed unconditionally and the operation is performed so that no mowing remains.

(Effects) As already mentioned, some known combine harvesters are equipped with an automatic running direction control device that automatically performs row alignment. This conventional device detects the direction of the seed yarn using a grain culm position sensor attached to the cutting rod, and if the seed yarn curves to the right as shown in Figure 2, it automatically steers the combine harvester in accordance with the curve. This makes it possible to adjust the conditions of the dividing rods. Therefore, in the reaping operation of a combine harvester, the seed yarns are sometimes harvested not only in the vertical direction (planting direction) but also in the horizontal direction, such as in circular cutting. In this case, for example, when planting 3 rows of seed yarn, the adjacent 3 rows may be slightly shifted laterally as shown in Figure 3. This shift may be large or small. There is a difference,
In other words, if the combine moves forward as it is, there will be some uncut material, so the direction of the combine must be adjusted, or if the combine continues to move forward, there will be no uncut material, so there is no need to adjust the direction of the combine. There is.

However, according to one aspect of the present invention, a grain culm position detection sensor 2 is provided on a cutting rod 1 provided in front of a combine harvester, and the right and left crawlers of the combine are automatically controlled based on the signal detected by the sensor 2, so that the cutting rod 1 1, the signal from the sensor 2 is used as the "LJ times signal" when the grain culm position deviates to the left with respect to the dividing rod 1 by more than a specified value. "1" to "14" indicates a deviation that does not leave any uncut material even if the combine moves forward.
``N'' signal when the grain culm position deviates to the right by more than a specified value. When the signal for the first grain culm is "N", the automatic running direction control device in the combine is configured so that the automatic control device is not activated. When there is no uncut material left even if the combine harvester is moved forward, the combine harvester automatically cuts the harvest without adjusting its direction, which has the effect of not automatically adjusting the combine harvester to the left or right unnecessarily.
