Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a reaping control device for a combine harvester, and is capable of accurately controlling reaping of the so-called middle reaping action in which uncut grain culms are present on both the left and right sides of the reaping row position. try to.

Conventional technology: A pair of left and right strike sensors are provided on the left and right outer portions of the reaping device, or on the grass cutting body on the negative side, which control the strike direction to follow the grain culm rows by interlocking the left and right strike clutches.

Problems to be Solved by the Invention In this configuration where only a pair of left and right direction sensors are provided, even if the reaping device can be moved along the grain culm rows on either the left or right side, When the horizontal spacing of the grain culms in the row in the area where the strike sensors on both left and right sides act changes greatly, if the reaping device deviates to the left-right side, adjacent grains outside the row will be removed on the other side. Unfavorable reaping conditions tend to occur in the next reaping process, such as reaping the culms or leaving unmown grain culms in the rows that should be reaped.

Means for Solving the Problems The present invention provides for the weeding bodies (
2) (In 31, there is a pair of left and right strike sensors that control the strike direction to follow the grain culm rows by interlocking the left and right strike clutches.
41 (5), and both strike direction sensors (4) (4) (5)
The combine harvester's reaping control device is configured so that when both detect a grain culm and when neither a grain culm is detected, the strike clutch (41(5) is not disengaged and the combine harvester is controlled in a straight-ahead state.

The operation and effect of the invention When reaping during the mid-splitting operation, grain culms are planted on both left and right sides of the sowing body (21 (3)), and this cropping body (2) and (3)
Harvest only the grain culm that is guided into the space between the grain. Grass plant (2
1 and 31 are both interposed in the interval between grain culm rows. For example, in the case of the example shown in the figure, when the strike sensor (4) installed on the left-hand weeding body (2) detects a grain culm, the left-hand strike clutch is disengaged. Correct the strike direction to the left and place the branch on the right side on the correspondence (3)
When the side strike sensor (5) detects the grain culm, the right side strike clutch is disengaged, the strike direction is corrected to the right, and the splitting body (21 (
31 is cut along the rows of grain culms. When both of these left and right strike direction sensors (4) and (5) detect a grain culm, or when neither of them detects a grain culm, the left and right strike direction clutches are not disengaged and the vehicle moves straight for reaping.

In this way, when the left and right pair of strike direction sensors (4-1 (5)) located on the outside of the reaping device (1) both detect a grain culm, and when neither of them detects a grain culm, the reaping device (1) ) is a left and right branch that is about to be reaped in order to go straight ahead +21
Not only when the spacing between grain culm rows corresponding to the spacing between By reducing this, it is possible to reduce the reaping of adjacent grain culms and the number of different grain culms in the reaping row, and it is possible to maintain accurate row cutting.

Embodiment In the illustrated example, the combine harvester is mounted on a chassis having a traveling device f61 +71 consisting of a pair of left and right crawlers.
A reaping device (1) is installed at the front, and this reaping device (1) is installed at the rear.
) is equipped with a threshing device that receives and threshes the grain culms harvested and transferred from ), and is capable of reaping, threshing, and traveling by the drive transmission of the prime mover. In front of the cutting blade of the reaping device (11), a grass divider (2+ +31) is provided protrudingly opposite the left and right ends of the width of the cutting blade, and a grass divider (8) is also provided in the middle of this blade. .

The left branch (2) has strike sensors (9) on both left and right sides.
(4) is projected, and this strike direction sensor (9) is connected to the branching body (
By detecting the stock base of the grain culm on the left side of 2) and rotating it to the rear side (A) around the support shaft (10), the running clutch Q11 of the right side traveling device (7) is disengaged. In order to correct the strike direction of the combine to the right side, the structure is interlocked with the control device (121). Also, the strike direction sensor (4
) is pushed by the row of grain culms on the right side and rotated backwards (b) around the support shaft (10), thereby causing the strike clutch (1:1) of the left traveling gear to disengage. Control device (1δ
It is configured to be linked via.

A strike direction sensor (5) which can be rotated around the support shaft is provided on the left side of the right-side dividing body (3), and this strike direction sensor (5) detects the grain culm row on the left side and ), the right traveling device (7) is rotated through the control device (121).
The transmission clutch (11) is interlocked to disengage the running clutch (11).

In combine harvester operation, in the case of so-called side mowing, in which the machine is positioned on the already cut ground side of the grain culm to reap, it is sufficient to move the cutting body (2) on the uncut grain culm side and reap. When the outer strike sensor [9] detects the grain culm row and is rotated in the direction of arrow (A), the right strike clutch (11) is disengaged and the running direction is corrected to the right. Also, when the right direction sensor (4) = 4- detects the grain culm row and is rotated in the direction of arrow (b),
When the left strike clutch (1) is disengaged to correct the running direction to the left, and both strike sensors (9) and (4) are in the activated neutral position, the combine harvests straight ahead.

When performing mid-split reaping, the right-hand tiller (3) is interposed between the rows of grain culms, so the strike direction sensor (5) of this tiller (31) can detect the rows of grain culms. in a state,
It is controlled by the relationship between this strike sensor (5) and the above-mentioned strike sensor (4), and when the strike sensor (4) detects a grain culm, the left strike clutch (13) is disengaged and the strike direction is corrected to the left. When the strike sensor (5) detects a grain culm, the right strike clutch (11) is disengaged and the strike direction is corrected to the right. Strike direction sensors on both left and right sides (4+ (4)
(5) both detect the grain culm, the double running clutch (+31
(Ill remains in the inserted state and does not turn off, the strike direction is straight ahead, and the strike direction sensors on both left and right sides (41 (5)
The same is true when both do not detect grain culms.

Each of the above-mentioned strike direction sensors (4), (5), and (91) may be configured to be in constant operation, but in the case of side mowing, the strike direction sensors (91
) (5) only works, and in the case of intermediate reaping, the strike direction sensor (4) works.
) (5) may be switched to work.
