Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a device for determining vertical or horizontal mowing in a combine harvester.

(Prior art) For the plants planted by a rice transplanter, if the direction in which the rice transplanter moves is vertical and the direction perpendicular to this is horizontal, the vertical spacing is narrower than the horizontal spacing, so the vertical and horizontal spacing is determined based on the spacing, and the actual work is carried out. There is a known system in which the machine itself uses a sensor to determine the current state of the machine, rather than the naked eye.

(Problems to be Solved by the Invention) However, in the known method, if there is no large difference in the spacing,
There was a defect that could not be accurately identified.

(Means for Solving the Problem) Therefore, the present invention provides a right sensor 6 and a left sensor 7 at the rear position of the weeding body 2 that enters between the rows among the weeding bodies of the combine, and the right sensor 6 and the left sensor 7 Configuration of a device for determining vertical or horizontal mowing in a combine harvester that determines vertical or horizontal mowing by providing a comparison unit 11 that compares a pattern memory 8 in which patterns to be used when moving between rows are classified in advance and a pattern IO being worked on That is.

(Structure) An embodiment of the present invention will be described with reference to the drawings. 1 is a clipper-type cutting blade, 2 is a left weeding body provided in front of it, 3 is a central weeding body, 4 is a right weeding body, and 4 is a right weeding body; Support rod 5 behind the grass
are provided with a right sensor 6 and a left sensor 7, respectively.

8 is a pattern memory in which the following information is stored in advance.

That is, as shown in FIG. 3, there are the following three relationships among the right sensor 6, left sensor 7, and stock 9 in the case of vertical cutting.

a... This is when the aircraft is moving diagonally with some deviation, and the left sensor 7 initially comes into contact with the stock 9, but as the aircraft advances, the right sensor 6 comes into contact with the stock 9.

b... This is a case of going straight. The right sensor 6 and the left sensor 7 move forward without contacting any stock 9.

C... This is the same case of going straight, but because the right sensor 6 is in contact with the stock 9 because it is going straight ahead.

(The reverse of the above is also possible.) The above three patterns are vertical cutting patterns. To summarize this further, it can be said that the right sensor 6 and the left sensor 7 do not come into contact with the plant 9 at the same time because the row spacing is wide in vertical mowing. That is, in case a, the right sensor 6 comes into contact with the stock 9 after the left sensor 7 leaves the stock 9. In case b, neither the right sensor 6 nor the left sensor 7 contacts the stock 9 from beginning to end.

In case C, the left sensor 7 does not come into contact with the stock 9 until the end.

On the other hand, the pattern shown in FIG. 4 is a case where the aircraft moves horizontally.

In this case, d...the right sensor 6 and the left sensor 7 contact the stock 9 at the same time.

Although the line d is shown as a straight line, it is the same even if it is slightly inclined.

In addition, 10 is a cutting pattern circuit, 11 is a comparison circuit, 12 is a row determination circuit, 13 is a lateral determination circuit, 14 is row cutting control, and 15
is horizontal mowing control.

(effect) Next, the action will be described.

The machine moves forward, and the left weeding body 2, the center weeding body 3, and the right weeding body 4 divide the grass, and the cutting blade 1 cuts the grass. In this case, when the machine is moving forward in the row cutting direction with respect to the stock 9, the pattern is one of a, b, and C in Figure 3, and the right sensor 6 and left sensor 7 do not contact at the same time. , either one is in a state away from stock 9. Therefore, the pattern of the cutting pattern circuit 10 sends its state to the comparison circuit 11, is compared with the memory of the pattern memory 8, is determined to be a row, and is subjected to the row cutting control 14.

Also, when the machine is moving forward in the horizontal cutting direction as shown in Figure 4, even if the moving direction is not in a straight line, both the right sensor 6 and the left sensor 7 are in contact with the stock 9. It is determined that horizontal mowing is being performed, and horizontal mowing control 15 is performed.

(Effect) As mentioned above, when the rice transplanter advances the rice transplanter vertically and the direction perpendicular to this is horizontally, the vertical interval is narrower than the horizontal interval, so the vertical and horizontal distances can be determined by the interval. There is a known system in which the machine itself uses a sensor to determine the current state of work, rather than the naked eye. but,
The above-mentioned known method has a defect that accurate discrimination cannot be made unless there is a large difference in the spacing.

However, in the present invention, the right sensor 6 and the left sensor 7 are provided at the rear of the weeding body 2 of the combine harvester that enters between the rows, and the pattern when the right sensor 6 and the left sensor 7 move between the rows is changed. Since the structure of the device for determining vertical or horizontal cutting in a combine harvester is provided with a comparing section 11 that compares the pattern memory 8 that has been classified by caulking and the pattern 10 being worked on to determine vertical or horizontal cutting, When the machine is moving forward in the row mowing direction relative to 9, the pattern is one of a, b, and c in Figure 3, and the right sensor 6 and left sensor 7 do not touch at the same time, but only one of them. is far away from stock 9. Therefore, the pattern of the reaping pattern circuit 10 sends its state to the comparator circuit 11 and the pattern memory 8
The row cutting control 14L is compared with the memory of
When the machine is moving forward in the horizontal cutting direction as shown in Fig. 4, both the right sensor 6 and the left sensor 7 contact the stock 9, even if the moving direction is not in a straight line. Since it is determined that it is mowing and the horizontal mowing control 15 is performed, accurate automatic control is possible regardless of the spacing of the plants 9.
