Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a handling depth 7A sectioning device for a combine harvester.

(Prior art) A plurality of sensors are provided in the length direction of the grain culm in the reaped grain culm conveyance path of a conventionally known combine harvester, and when the tip of the grain culm does not reach the sensor on the front side, it is treated shallowly, and the grain culm is handled shallowly. When the tip of the ear reaches the sensor, the depth of handling is determined, so a device that can automatically adjust the depth of handling using both sensors is known.

(Problem to be Solved by the Invention) However, the known device is configured so that both sensors always maintain a constant handling depth, and the system is designed to maintain a board state or a deep handling state with special care. It is not possible to make it thresh, but depending on the variety, there are grain culms with many late ears, and grain culms with no late ears at all, so it is advantageous to treat grain culms with many late ears in depth. In the case of grain culms that have no delayed ears, it is advantageous to treat them shallowly as this will generate less dust.

(Means for solving the problem) The above-mentioned adjustment of cross board threshing and deep handling threshing can be easily carried out by shifting the mounting position of the sensor toward the grain culm, but the method of shifting the mounting position of the sensor is The present invention makes it possible to carry out this without changing the position of the sensor, and also because it is too sensitive if it were activated as soon as the tip of the sensor came in contact with the sensor. The reaping section 17 and threshing section 19 have also been improved.
, a conveyance section 18 extending from the reaping section 17 to the threshing section 19 , a stock side sensor 10 and a ear side sensor ll provided in the conveyance section 18 and arranged in parallel in the grain culm direction, and the sensor 10 . 11, the handling depth adjustment section 20 is provided with a switching section 16 for 13 for cross board, 15 for deep handling, and 14 for standard use, and when set to 13 for cross board. When the tip 9 has not reached the stock side sensor 10, move forward, when it has reached the stock side sensor 10, move backward, and when the tip 9 has not reached the tip side sensor 11 when set to 15 for deep handling. When it moves forward and reaches the tip side sensor 11, it moves backward,
In the case of the standard type 14, a time lag circuit is provided in the circuit of the sensor 10 and 11 in the handling depth adjustment device in a combine harvester that repeats forward and backward movement between the stock side sensor 10 and the tip side sensor 11. The tip of the tip 9 is connected to the sensor 10.
This invention summarizes the structure of a handling depth adjustment device for a combine harvester, which is configured so that it does not operate as soon as it approaches or leaves the harvester.

To explain one embodiment of the present invention with the drawing, l is a branch,
Reference numeral 2 denotes a grain culm lifting device, and a cutting blade 3 for cutting the root of the raised grain culm is provided behind it. The grass cutting body 1, grain culm pulling device 2, and cutting blade 3 serve as a reaping section 17. 4 is a traveling device;
Reference numeral 5 denotes a threshing room of the threshing section 19, and between the reaping section 17 and the threshing section 19 there is a conveying section 18 consisting of a root-side conveying device 6 and a tip-side conveying device 7 for conveying the harvested grain culms to the threshing section 19. is provided. Reference numeral 8 indicates a plurality of sensors for detecting the tips 9 of grain culms conveyed by the root-side conveyance device 6 and the ear-side conveyance device 7, which are provided at intervals in the length direction of the grain culms, and 10 denotes sensors on the stock side. The sensor 11 is a tip side sensor, and these are all known.

Therefore, as shown in FIG. 6, the controller 12 is provided with a changeover switch 16 for a crosspiece 13, a standard 14, and a deep handling 15. When the change-over switch 16 is changed to the one for the crosspiece 13, as shown in Fig. 7, the stock side sensor 10 is OFF, and when the head side sensor 11 is OFF, the grain culm moves forward in the culm direction and becomes deep handling. When the stock side sensor 10 is ON and the head side sensor 11 is OFF, the grain culm retreats toward the culm body and is handled shallowly, and when the stock side sensor 10 is ON, the grain culm is When the side sensor 11 is ON, the vehicle moves backward and is adjusted to be handled shallowly.

When the changeover switch 16 is switched to the deep handling use 15, the 1 stock head side sensor 10 is OFF and the tip side sensor 11 is OFF.
At this time, the grain culm advances toward the culm and is adjusted so that it can be handled deeply, and when the stock side sensor 10 is ON and the ear side sensor 11 is OFF, the grain culm advances toward the culm. It is adjusted so that it can be handled deeply, and when the stock side sensor 10 is ON and the tip side sensor 11 is ON, it is adjusted so that it is treated shallowly.

When the selector switch 16 is switched to the standard type 14, the stock side sensor 10 is OFF and the tip side sensor 11 is OFF.
At this time, the grain culm advances toward the culm and is adjusted so that it can be handled deeply, and when the stock side sensor 10 is ON and the ear side sensor 11 is OFF, it stops there, and the stock side sensor 10 is ON and the tip side sensor 11 is ON, the blade moves backward and is adjusted so that it can be handled shallowly.

Therefore, in the second embodiment, the output interval time of detection is determined, and when the tip 9 does not reach the stock side sensor 10, the output interval is as short as 1 second, and when the tip 9 does not reach the stock side sensor 10, the output interval is as short as 1 second. The output interval is as long as 5 seconds when the tip reaches the sensor 10 but not the tip side sensor 11, and the output interval is as short as 1 second when the tip 9 reaches the tip side sensor 11. It is configured as a handling depth adjustment device.

FIG. 8 is a delay diagram of the stock side sensor 10 and the ear tip side sensor 11, and when it cuts into the crosspiece plate 13, it takes 0.1 seconds after the ear 9 contacts the stock side sensor 10. If the condition continues, it will turn ON, and if it continues for 0.9 seconds and you are away from it, it will turn OFF. In addition, in the standard case, the sensor 10 turns ON when the grain 9 contacts the stock side sensor 10 for 0.5 seconds, and turns OFF when it continues for 0.5 seconds and leaves. In addition, when switching to the deep handling mode 15, if the grain 9 contacts the stock side sensor 10 and remains in that state for 0.9 seconds, it will turn ON, and if it continues for 0.1 seconds and leaves, it will turn OFF. Become.

Also, when switching to the cross plate 13, it turns ON when the grain 9 contacts the tip side sensor 11 and remains in that state for 0.1 seconds, and turns OFF when it continues for 0.5 seconds and leaves. .

In addition, in the standard case, when the ear 9 contacts the ear tip side sensor 11 and remains in that state for 0.5 seconds, it turns on, and when it continues for 0.3 seconds and leaves, it turns off. Also, for deep handling 1
When switched to 5, the state remains ON for 0.9 seconds after the ear 9 contacts the ear tip side sensor 11, and turns OFF when the sensor 11 continues for 0.1 seconds and leaves.

(effect) Next, we will discuss the effect.

With the above configuration, without changing the positions of the stock side sensor 10 and the tip side sensor 11, the adjustment of the cross plate 13, deep handling 15, and standard 14 can be done by simply switching the changeover switch 16. can.

That is, when the changeover switch 16 is switched to the crossbar 13, the grass is divided by the grass cutting body 1, the grain is pulled up by the grain culm pulling device 2, the grain is cut by the cutting blade 3, and the grain is transferred to the root side conveying device 6. When the ears 9 conveyed toward the threshing room 5 by the ear-side conveying device 7 do not reach the stock head side sensor 10, the one-stock head side sensor 10
is OFF, and the tip side sensor 11 is also OFF, so the adjustment is made so that it is further advanced and deeper than the table shown in FIG.

There are many known examples of this adjustment mechanism itself, and any of them may be used.

In this case, the sensing of the stock side sensor 10 and the tip side sensor 11 is measured every 1 second, so it is still OFF after 1 second.
, if it is in the OFF state, it will be adjusted to deep treatment again. Then, eventually the tip 9 reaches the stock side sensor 10, and if it continues to touch for 0.1 seconds, the stock side sensor 10
Turn on. However, since the tip 9 has not reached the tip side sensor 11, the tip side sensor 11 is OFF.
Conventionally, this state is regarded as a proper state and threshing is continued in a fixed manner, but in the present invention, since shallow handling is performed, when the stock side sensor 10 is turned on, the grain is moved back and adjusted to become shallow handling. . Therefore, as a result of measurement every 5 seconds, if the tip 9 reaches the stock sensor 10, the tip 9 will leave the stock sensor 10, and if this state continues for 0.9 seconds, the stock sensor 10 will be removed. Turn it off again.

Therefore, when the changeover switch 16 is set to the cross plate 13, the tip 9 continuously arrives at and leaves the plant head side sensor 10, and in short, it is treated shallowly.

When the selector switch 16 is set to standard 14, unlike the case of shallow handling, no adjustment is made as long as the stock side sensor 10 remains ON and the tip side sensor 11 remains OFF. When sensor 10 continues to be in contact for 0.5 seconds, it turns ON, and when the tip side sensor 11 also continues to touch for 0.15 seconds and turns ON, it is adjusted to shallow handling for the first time, so in short, standard handling is performed.

When the changeover switch 16 is set to deep handling 15, the stock side sensor 10 is ON and the tip side sensor 11 is OFF.
Adjust so that it can be treated deeply. Then, the tip 9 eventually reaches the tip side sensor 11 and continues to make contact for 0.9 seconds, turning on the tip side sensor 11. This state is detected every second, so if the tip of the tip 9 continues to separate from the tip side sensor 11 for 0.1 seconds after one second, the stock side sensor 10 will be ON and the tip side sensor 11 will be OFF. However, in this state, the adjustment is made so that the grain is handled deeply, so in short, the grain tip 9 is threshed and treated in a state where it reaches and leaves the grain-side sensor 11.

(Effects) A plurality of sensors are installed in the length direction of the grain culm in the reaped grain culm conveyance path of a conventionally known combine harvester. When the tip of the ear reaches the sensor, the depth of handling is reached, so a device for automatically adjusting the depth of handling using a single sensor is known.

However, the known method is configured so that the handling depth is always constant using both sensors, and it is not possible to consciously maintain the cross-board state or deep handling state while threshing. Depending on the grain, there are grain culms with many late ears, and there are also grain culms with no late ears at all, so in the case of grain culms with many late ears, it is more advantageous to treat them in detail, and grain culms with no late ears at all. In this case, it is advantageous to treat it lightly as it will generate less dust.

However, the present invention includes the reaping section 17, the threshing section 19, the conveying section 18 from the reaping section 17 to the threshing section 19, and the conveying section 18.
A stock-side sensor 10 and a ear-side sensor 11 that are arranged in parallel in the grain killing direction of the grain culm, and the sensor 1
It has a handling depth adjustment part 20 that operates at 0.11, and the handling depth adjustment part 20 is provided with a switching part 16 for 13 for corrugated sheet, 15 for deep handling, and 14 for standard use, and 13 for corrugated sheet. When the tip 9 does not reach the sensor 10 on the stock side, it moves forward, and when it reaches the sensor 10 on the stock side, it moves backward, and when it is set to deep handling 5, the tip 9 does not reach the sensor 11 on the tip side. When it reaches the tip side sensor 11, it moves forward, and when it reaches the tip side sensor 11, it moves backward.
4, a time lag circuit is provided in the circuit of the sensors 10 and 11 in the handling depth adjustment device for a combine harvester that repeatedly moves forward and backward between the stock side sensor 10 and the tip side sensor 11, and the tip A handling depth adjustment device in a combine harvester configured so that it does not operate immediately even if the sensor 9 approaches and separates from the sensor 10.11. Changeover switch 16
When switching to the corrugated plate 13, as shown in Fig. 7, the plant side sensor 10 is OFF, and when the tip side sensor 11 is OFF, the grain culm advances toward the culm and is adjusted so that it can be handled deeply. 2 plants, the base side sensor 10 is ON and the tip side sensor 11 is ON.
When is OFF, the grain culm retreats toward the culm and is adjusted so that it is treated shallowly.When the sensor 10 on the root side of one plant is ON and the sensor 11 on the tip side is ON, the grain culm retreats toward the culm and is treated shallowly. When the selector switch 16 is set to deep handling 15, the stock side sensor 10 is OFF, and when the head side sensor 11 is OFF, the grain culm moves forward in the culm direction and becomes deep handling. The sensor 10 on the stock side is turned on.
When the head side sensor 11 is OFF, the grain culm moves forward in the direction of the culm and is adjusted so as to be handled deeply, and when the 1-plant base side sensor 10 is ON and the head side sensor 11 is ON, the grain culm moves backward, When the switch 16 is adjusted to be shallow and the switch 16 is set to the standard 14, the stock side sensor 10 is OFF.
F. When the head side sensor 11 is OFF, the grain culm moves forward in the direction of the culm and is adjusted so that it can be deeply handled. When the machine stops and the stock side sensor 10 is ON and the tip side sensor 11 is ON, it moves backward and is adjusted to be on the cross plate, and when it switches to the corrugated plate 13, the film is applied to the stock side sensor IO. It turns ON when the state continues for 0.1 seconds after seed 9 makes contact, and turns OFF when it continues for 0.9 seconds and leaves.
In the standard case, if this state continues for 005 seconds after the membrane type 9 contacts the stock side sensor 10, it will turn ON and 0.
It turns OFF when the sensor is separated for 5 seconds, and turns OFF when it is switched to deep handling 15, and when the state continues for 0.9 seconds after the film type 9 contacts the stock side sensor 10, it turns ON.
If it continues for 1 second and you are away from it, it will turn OFF, and the
When switched to 3, it will turn ON if the state continues for 0.1 seconds after the membrane type 9 contacts the tip side sensor 11, and it will turn OFF if it continues for 0.5 seconds and leaves.In the standard case, the tip When the membrane type 9 comes into contact with the side sensor 11 and remains in that state for 0.5 seconds, it turns ON, and when it continues for 0.3 seconds and leaves, it turns OFF, and when it switches to the deep handling type 15, the tip If the membrane type 9 comes in contact with the side sensor 11 and remains in that state for 0.9 seconds, it will turn ON, and if it continues for 0.1 seconds and is separated, it will turn OFF, so it will not work if there is a momentary contact, so it cannot be activated frequently. It can prevent defects caused by movement.

In addition, in the case of deep handling, it can be quickly positioned on the cross board, and in the case of a cross board, it can be quickly positioned on the cross board.
．． It is possible to take more than 11 intervals.
