Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a direction control device for a combine harvester.

(Prior Art) A combine harvester having conventional single-row mowing sensors A, B, horizontal mowing sensors C, D, and grain culm presence/absence sensors E, F is known.

The row mowing sensors A and B start operating when either one of the grain culm presence sensors E and F is turned on, and performs row width determination.

The row width determination by row mowing sensors A and B is that if they do not touch each other even though they have moved forward a certain distance, it will be determined as one row, and if both row mowing sensors A and B are in contact, it will be determined as "horizontal". do. Furthermore, when either one of the row cutting sensors A and H is in contact, the distance between the plants in contact is measured, and the row width is determined from this.

(Problems to be Solved by the Invention) The known combine harvester has the following problems:
One must be determined. If it is determined that there is a row, the direction of the combine is controlled by the row cutting sensor. When it is determined that the mowing is on the side, the direction of the combine is controlled by the horizontal mowing sensor.

The row width is determined by row cutting sensors A and B. If the start happens to be successful, the row cutting sensors A and B enter the center of the stock, and the grain culm presence sensors E and F installed at the rear of the hoisting device are pushed by the cut grain culms and turn ON. Mowing sensors A and B start to operate, but neither may come into contact with the plant. In this case, it is determined that it is a row because the distance between the plants is wide.

Since the plants are densely planted horizontally, one or both of the row cutting sensors A and H always come into contact with the plants during horizontal cutting.

Even if row cutting sensors A and B both touch the stock, it cannot immediately be determined that it is horizontal. 0 If the aircraft starts in a crooked manner, one row cutting sensor A or H will come into contact with the stock even if the space between rows is wide. It is from. Therefore, the distance between the plants is measured by the row cutting sensors A and H after driving for a certain distance, and it is determined whether the plants are in rows or horizontally.

However, when operated by someone who is not familiar with the operation, the row mowing sensors A and H may enter later than the horizontal mowing sensors C and D, as shown in Fig. 1. When entering in this state, the grain culm presence sensor F installed behind the horizontal mowing sensors C and D will immediately turn ON, so it will be activated even though the row mowing sensors A and B have not yet reached the culm. The problem with the conventional method is that it is determined to be an article.

Therefore, in the present invention, grain culm presence/absence sensors E and F are activated only when both of them are turned on, so that row width can be determined accurately even in the case shown in Fig. 1. By doing this, you can easily overcome the problem.

(Means for solving the problem) The present invention provides row mowing sensors A and B, horizontal mowing sensor C,
D, and grain culm presence/absence sensors E, F, in which the row width is determined by the row cutting sensors A, H, the row width determination by the row cutting sensors A, H is carried out by the grain culm presence/absence sensors E, This is a directional control device for a combine harvester that performs the operation after both F and F are turned on, thereby making it possible to accurately judge the row width regardless of the attitude of the machine.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 indicates a cutting section, 2 a weeding rod, 3 a weeding tool provided at the tip of the weeding rod 2, and 4
is a pulling device, and the row cutting sensor A is attached to the weeding tool 3 on the left side.
, B are installed, and the horizontal mowing sensor C is attached to the right side weeding tool 3.
, D are attached. The grain culm presence sensor E is a grain culm presence sensor installed behind the row mowing sensors A and H, and the grain culm presence sensor F is a grain culm presence sensor F installed behind the horizontal mowing sensor C1D.

5 is a cutting blade, 6 is a controller, 7 is a right solenoid valve, 8 is a left solenoid valve, 9 is a controller switch, and 10 is a field with a culm.

(effect) Next, we will discuss the effect.

As the machine moves forward, each weeding tool 3 rushes between the plants, but at that time, the machine bends and moves into the field 1 as shown in Figure 1.
It may go to 0. In the case of Fig. 1, the horizontal mowing sensors C and D immediately enter the field 10 and are raised by the lifting device 4, turning on the grain culm presence sensor F, but even in that case, the row mowing sensors A and H The other side is still in field 1.
However, in the conventional type, when the grain culm presence sensor F turns on, the row mowing sensor A is activated.

B starts the row width judgment, but in the case of the present invention, the row cutting sensors A and B enter, and the grain culm presence/absence sensor E turns OFF.
Since the row width determination is not made unless the result is N, erroneous determination is prevented.

(Effects) Conventionally, a combine harvester having row mowing sensors A and B, horizontal mowing sensors C and D, and grain culm presence sensors E and F is known. Row cutting sensors A and B are grain culm presence sensors E and F.
When one of these switches is turned on, it starts operating and performs row width determination.
.

When B enters the field further than horizontal mowing sensors C and D, grain culm presence sensor F installed behind horizontal mowing sensors C and D is immediately turned ON, so row mowing sensors A and B The problem with the conventional method is that it starts operating even though the culm has not yet reached the culm, and it is judged as a ray.

However, the present invention uses row mowing sensors A and B, horizontal mowing sensors C and D, and grain culm presence sensor E.

F, in which the row width is determined by the row mowing sensors A and H, the row width determination by the row mowing sensors A and B is performed after both of the grain culm presence sensors E and F are turned on. This is because the directional control device in the combine is configured so that it can accurately judge the row width regardless of the attitude of the machine, so even if single row cutting sensors A and B enter the field after a delay. , row mowing sensor A, row mowing sensor A unless grain culm presence sensor E behind B turns ON.

Since B does not perform the row/width determination, it has the effect of preventing the aforementioned defects and preventing erroneous determination.
