BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is provided with a cutting unit capable of raising and lowering a grain culm freely, a transport device for transporting the harvested grain culm, and a threshing device for threshing the transported grain culm. On the basis of information on the tip position detecting means for detecting the tip position of the grain stem conveyed by the conveying device, the handling depth adjusting means for adjusting the handling depth in the threshing device, and the tip position detecting means, And control means for operating the handling depth adjusting means to maintain the target handling depth.

2. Description of the Related Art When a harvesting operation is completed and one leaves the field, in order to prevent the front end of the cutting unit from colliding with a ridge, the cutting unit is stopped shortly before the cutting operation is completely interrupted or completed. It is a common practice to raise. In such a case, when the handling depth adjusting means is operated based only on the information of the tip position detecting means, a change in the grain stalk length (the length from the grain stalk support point to the tip of the stalk by the transport device),
In this case, it is difficult to follow the change in the shortening direction, and there is a tendency that the surface is handled shallowly.

Therefore, for example, in a state where the cereal stalk presence / absence detecting means provided at the start end side of the conveying device for detecting the presence / absence of a cereal culm detects the presence of a cereal culm, the mowing unit continuously operates for a set time or a set amount. When the operation is performed on the ascending side, the reaping work 1
It is considered that it is determined that the raising operation of the mowing part has been performed at the end of one stroke, and the occurrence of shallow handling is avoided by operating the handling depth adjusting means to the deep handling side.
Note that after such an operation to the deep handling side, the handling depth control based on the detection information of the tip position detecting means is prohibited (for example, Japanese Patent Application No. Hei.
-151005).

In the above conventional means, after the handling depth adjusting means is operated to the deep handling side in accordance with the raising operation of the mowing part, the handling depth based on the information of the tip position detecting means is obtained. Since the operation of the adjusting means is prohibited, even if the grain culm length of the cereal culm conveyed by the conveying device is long, the inconvenience of unnecessarily adjusting the cereal stem to the shallower side is avoided.
However, when a shorter culm length culm is transported,
Since the handling depth adjustment operation is prohibited, it is not possible to respond to the change, and there is a possibility that shallow handling may occur.

[0005] In addition, the transport device is generally configured to be transported and driven in conjunction with the traveling of the combiner regardless of the raising operation of the reaping unit. Even if the cereals are no longer transported, a predetermined amount of cereals remaining inside the transport device is transported to the threshing device while traveling a predetermined travel distance (for example, 2 m). Therefore, even in this case, it is necessary to adjust the handling depth according to the change in the grain stalk length of the grain culm to be conveyed so as not to cause shallow handling.

A feature of a combine depth control device according to the present invention is that a grain stalk presence / absence detecting means for detecting the presence / absence of a grain culm is provided at a starting end of the conveyor. The means, when the harvesting section is operated to the rising side continuously for a set time or a set amount in a state where the grain stalk presence / absence detecting means detects the presence of the grain stalk, moves the handling depth adjusting means to the deep handling side. While operating to the deep handling side associated with the raising operation of the mowing part, the cereal stalk presence / absence detecting means detects the cereal stalk absence state and then travels a predetermined traveling distance or a predetermined time. Until the passage, the operation of the handling depth adjusting means based on the information of the tip position detecting means is configured to be permitted only to the deep handling side.

According to the characteristic structure of the present invention, even when the handling depth adjusting means is operated to the deep handling side in accordance with the raising operation of the cutting unit, the length of the grain culm conveyed becomes short. In response to the change, the handling depth adjusting means is operated to the deep handling side, so that the occurrence of shallow handling can be avoided. On the other hand, when the grain culm length of the grain culm to be transported becomes long, the handling depth adjusting means is not operated, and the handling depth state is maintained, so that there is also a disadvantage that the handling depth is unnecessarily adjusted to the shallow handling side. Will be avoided.

Further, the handling depth adjusting means based on the information of the tip position detecting means, until the stalk presence / absence detecting means detects the absence of cereal stalk and travels a predetermined traveling distance or until a predetermined time elapses. Since only the operation to the deep handling side is allowed, the predetermined distance of grain culm remaining in the conveyor after the raising operation of the mowing part is transported to the threshing machine, the travel distance or travel time required If the predetermined traveling distance or the predetermined time is set, even if the grain culm length of the grain culm to be conveyed becomes short, it is possible to cope with the change and to effectively avoid the occurrence of shallow handling.

Therefore, according to the characteristic configuration of the present invention, when raising the mowing section to interrupt or terminate the mowing operation, the shallow handling occurs even when the grain culm length changes. Thus, it is possible to obtain a combine depth control device which can be effectively avoided, and which is more easy to use and can effectively control the depth.

First, the handling depth is adjusted by confirming that both the start command switch 22 and the threshing switch 19 are in the ON state, and then checking whether the culm is present by the stock sensor 21. Or to detect. Stock sensor 21 is ON
If the state is the state, it is determined that the culm is supplied to the transport device 8 and the harvesting operation is being performed, and the state after the handling depth adjusting means C is operated to the deep handling side for cutting. It is determined whether or not the state is the state after the operation toward the deep handling side, and the state of the selection switch 25 is checked. If it is OFF, the normal handling depth control described later is performed. If the selection switch 25 is in the ON state, it is determined whether the mowing unit B has been continuously operated to the ascending side for a set time or more within a predetermined time, and if the ascent operation has not been performed, the normal handling depth control is performed.

When the lower tip sensor S2 is in the OFF state and the upper tip sensor S1 is in the OFF state, since the tip sensor is located on the shallow handling side, it is adjusted to the deep handling side after elapse of the delay time. When the lower tip sensor S2 is in the OFF state and the upper tip sensor S1 is in the ON state, it is determined that there is a detection error due to the floating stirrer, the control operation is immediately stopped, and the alarm device 24 is activated. To indicate that a floating straw is occurring.

Further, in the above embodiment, after the harvesting section B is operated to the deep handling side in accordance with the lifting operation, the cereal stalk presence / absence detecting means 21 detects the absence of cereal stalks from the predetermined travel distance (for example, 2m), the operation of the handling depth adjusting means C based on the information of the tip position detecting means S1 and S2 is allowed only to the deep handling side. Instead of the distance, it may be until a predetermined time elapses. In this case, the predetermined time is set equal to the time required for the combine to travel the predetermined travel distance.
