Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a handle depth adjusting device in a combine.

(Prior Art) In the publicly known Japanese Utility Model Publication No. Sho 57-18328, a mowing section for mowing grain culms, a threshing section for threshing grain culms mown by the mowing section, and a threshing section from the mowing section. In the one having a transfer takeover section up to, a plurality of sensors for detecting the length in the culm direction of the grain culvert provided in the reaping section, and a handling depth adjusting section operated by the sensors, depending on the state of the grain culm. The one that tries to adjust the handling depth adjuster is described.

Further, JP-A-53-86330 discloses a technique for adjusting the handling depth by using or not using a pulse that is constantly generated.

(Problems to be Solved by the Invention) Among the above-mentioned known examples, those described in Japanese Utility Model Publication No. Sho 57-18328 have mowing grain stems that are upright or have ears drooping. Some of them have drooping tips, so the grain culm length cannot be measured accurately, so when measuring with a sensor, use the one that measures a little longer in anticipation of that amount, and as a result, the handling depth adjustment unit. It is not intended to intentionally handle shallowly or deeply because it is intended to adjust. However, depending on the variety, grain culms with many delayed ears,
There are also some culms that have no delayed ears. If the delayed ear is supplied to the threshing room in a normal state, it cannot reach threshing because it does not reach the handling barrel. Therefore, if you carefully adjust the depth, you can reach the handling barrel and thresh. However, deep treatment produces a large amount of straw debris, so in the case of grain culms with no delayed ears, it is advantageous to use shallow treatment as much as possible. Therefore, it is advisable to consciously adjust to a shallow handling and thresh, but the above-mentioned known example cannot do so.

Further, JP-A-53-86330 discloses only the technique of adjusting the handling depth by using or not using the pulse that is constantly generated, and the delayed spikes caused by the variety Threshing that corresponds to a large number of culms or culms without any delayed ears is not possible.

(Means for Solving the Problem) Therefore, the present invention provides a mowing unit for mowing grain culms, a threshing unit for threshing grain culms cut by the mowing unit, and a transfer handover from the mowing unit to the threshing unit. Section, the root side sensor and the tip side sensor, which are provided side by side in the grain direction of the grain culvert provided in the transfer and transfer section, and the both sensors to operate to move the tip forward and backward in the grain direction (this specification). In the book, moving the grain culm to the tip side along the culm direction is called forward, and moving it to the root side is called backward). The section is provided with a switching unit that can switch between shallow handling, deep handling and standard use, and when the switching unit is switched to shallow handling, the tip is not reached when the tip side sensor is reached. Move forward in the direction of the culm and when the tip reaches the above-mentioned sensor on the stock side, remove the tip. When the tip is not reaching the tip side sensor when the switching portion is switched to deep-cutting, the tip is moved forward in the tip direction and the tip reaches the tip side sensor. When the tip is moved backward in the direction of the stem, and when the switching unit is switched to the standard, the tip is a combine that repeats forward and backward movement in the direction of the stem between the stock origin side sensor and the tip side sensor. It is a device for adjusting the handling depth in.

Further, the present invention provides a mowing unit for mowing grain culms, a threshing unit for threshing grain culms cut by the mowing unit, a transport takeover unit from the mowing unit to the deblurring unit, and the transport takeover unit. In the one having a stocker side sensor and a tip side sensor which are provided in parallel in the culm direction of the provided grain culm, and a handling depth adjusting section which can be operated by both sensors to move the ears forward and backward in the culm direction. And, the handling depth adjusting unit is provided with a switching unit capable of switching between shallow handling, deep handling and standard use, and when the switching unit is switched to shallow handling, the tip of the tip serves as the stock side sensor. If not reached, the tip is moved forward in the direction of the culm, and when the tip reaches the stock sensor, the tip is moved backward in the direction of the culm, and the tip is moved when the switching unit is switched to deep treatment. When it does not reach the tip side sensor, the tip is moved forward in the direction of the culm and the tip becomes When the tip side sensor is reached, the tip is moved backward in the direction of the culm, and when the switching unit is switched to standard, the tip is in the direction of the ridge between the stock origin side sensor and the tip side sensor. In a depth control device in a combine that repeats forward and backward movement, when the tip is advanced in the direction of the culm while the tip does not reach the root sensor, and when the tip reaches the tip sensor and moves backward in the ridge direction. The output interval of the controller is set short when it is used, and the output interval of the controller when the tip is moved backward in the culm direction while the tip has reached the sensor on the plant side is used as a handle depth adjusting device in the combine. Is.

(Example) An example of the present invention will be described with reference to the drawings.
2 is a grain culm raising device behind the grass body 1, 3 is a cutting blade, 4 is a lower traveling device, 5 is a threshing chamber, 6 is a root side transfer device,
7 and the tip side transfer device, 8 are a plurality of sensors for detecting the tips 9 of the culms that are transferred and transferred by the root side transfer device 6 and the cusp side transfer device 7, and are spaced in the length direction of the culms. Is set up. Reference numeral 10 is a stock-side sensor, and 11 is a tip-side sensor, all of which are publicly known. Therefore, as shown in FIG. 6, the controller 12 is provided with a switching unit 16 for shallow handling, standard handling 14, and deep handling.

Reference numeral 17 is a mowing section, 18 is a transfer and transfer section including the root side transfer and transfer apparatus 6 and the tip side transfer and transfer apparatus 7, 19 is a threshing section, 20
Shows a handling depth adjusting section for moving the root side transfer device 6 in the direction of the culm.

When the switching unit 16 switches to the shallow handling 13, the stock side sensor 10 is turned off as shown in the "shallow" column in FIG.
When the tip side sensor 11 is OFF, the grain culm advances in the direction of the culm and becomes deeply treated, and when the root side sensor 10 is ON and the tip side sensor 11 is OFF, the grain culm retreats in the culm direction. When it becomes shallow handling, the stock side sensor 10 is turned on, and the tip side sensor 10 is turned on, it is retracted in the direction of the culm and adjusted so as to be shallow handling.

When the switching unit 16 is switched to the standard 14, as shown in the column of "Standard" in Fig. 7, when the root side sensor 10 is OFF and the tip side sensor 11 is OFF, the grain culm is in the culm direction. To the deep side, and the stock side sensor 10 is ON and the tip side sensor
When 11 is OFF, it stops and does not move, and the stock side sensor 10 is ON,
When the tip sensor 11 is turned on, the tip side sensor 11 is retracted in the direction of the culm and is adjusted to be a shallow handle.

When the switching unit 16 is switched to the deep handling 15, as shown in the column of "Deep eye" in Fig. 7, when the plant side sensor 10 is OFF and the tip side sensor 11 is OFF, the grain culm is culm. It moves forward and becomes deeply treated, and the tip side sensor is turned on when the stock side sensor 10 is ON.
Even when 11 is OFF, the grain culm moves forward in the culm direction and becomes deeply handled, and when the root side sensor 10 is ON and the tip side sensor 11 is ON, it retreats in the culm direction and becomes a shallow handling. Adjusted.

In the second embodiment, however, the output interval time of the controller 12 is set, and the output interval is 1 when the tip 9 does not reach the root sensor 10 or the tip sensor 11.
In a short time, the output interval is long as 5 seconds when the tip 9 has reached the tip side sensor 10 but not the tip side sensor 11, and the tip 9 is of course the tip side of the tip side sensor 10. When the sensor 11 is also reached, the output interval should be as short as 1 second.

(Operation) Next, the operation will be described.

With the above configuration, even if the positions of the stock side sensor 10 and the tip side sensor 11 are not changed, the shallow handling 13 and the deep handling 1
5、14 for standard can be adjusted by switching the switching unit 16.

That is, if the switching unit 16 is switched to the shallow handling 13, the grass body 1
And the cutting blade 3
9 which is cut by and is conveyed toward the threshing chamber 5 by the root side takeover transfer device 6 and the tip side takeover transfer device 7.
However, the tip side sensor 11 of course does not reach the stock side sensor 10, and in FIG. 3, both the stock side sensor 10 and the tip side sensor 11 are OFF, so from the table in FIG. It moves forward to the body and is adjusted deeply. There are many known examples of this adjustment mechanism itself, and any of them may be used. In this case, the output is measured by the controller 12 every second, so after 1 second, the stock side sensor
If both 10 and the tip side sensor 11 are OFF, the grain culm again advances in the culm direction. In this way, it is quickly adjusted at short intervals, and eventually the tip 9 reaches the stock side sensor 10, the stock side sensor 10 is turned on, and the tip side sensor 11 is turned off.
To the state of. This state is proper, but the switching unit
Since the 16 is switched to the shallow handling 13, the stock side sensor 10
When ON and the tip side sensor 11 is OFF, the grain culm retreats in the direction of the culm from Fig. 7, but this retreat does not need to be done quickly, so it is output from the controller 12 every 5 seconds and adjusted slowly. After 5 seconds, the stock side sensor 10 is still
When ON and the tip side sensor 11 is OFF, the controller 1
It is output again from 2 and adjusted. Therefore, shallow handling is possible.

When the switching unit 16 is set to the standard 14, the tip side sensor 11 and of course the stock side sensor 10 are not reached.
Both the origin sensor 10 and the tip sensor 11 are OF
Since it is F, the grain culm is advanced in the direction of the culm and is adjusted deeply from the table of FIG. The adjustment in this case is performed every 1 second by the controller 12, and after 1 second has elapsed, if both the stocker side sensor 10 and the tip side sensor 11 are still OFF, the grain culm again advances in the culm direction. In this way, the tip 9 reaches the stock-side sensor 10 in a short time and is quickly adjusted, and the stock-side sensor 10 is turned on. However, although the tip side sensor 11 is in the OFF state, this state is a proper state because it is standard, but there is no output from the controller 12 because the switching unit 16 is switched to the shallow handling 13. , And stop, and perform threshing threshing.

When the switching unit 16 is switched to the deep-use 15, the tip 9 does not reach the tip side sensor 11 as well as the tip side sensor 10. In FIG. 3, both the tip side sensor 10 and the tip side sensor 11 are OFF. Therefore, according to the table of FIG. 7, the grain culm is advanced in the direction of the culm and is adjusted deeply. In this case, the controller
The output from 12 is output every 1 second and advances toward the culm, 1
After 10 seconds, the stock side sensor 10 and the tip side sensor are still
If both 11 are OFF, the grain culm advances toward the culm again. In this way, the tip 9 reaches the stock-side sensor 10 and the stock-side sensor 10
Is turned on and the tip side sensor 11 is turned off. But,
With the “deep” output, the grain culm is adjusted to move forward in the culm direction every 5 seconds, and finally the stocker side sensor 10 is turned on and the tip side sensor 11 is also turned on. If this happens, the forward movement in the direction of the culm will proceed too far forward, so output it from the controller 12 at a short interval of 1 second, retract the grain culm in the direction of the culm and turn off the tip side sensor 11. , Repeat this, and treat deeply.

(Effects) Among the above-mentioned known examples, those described in Japanese Utility Model Publication No. Sho 57-18328 are grain culms with many delayed ears caused by varieties,
Further, there is no description of a technique for dealing with a grain culm having no delayed ear. Rice varieties include varieties with many delayed ears and varieties with no delayed ears. If the delayed ears are supplied to the threshing room in a normal state, they cannot reach the handling barrel and cannot be threshed. Therefore, if you consciously adjust to deep handling, you can reach the handling barrel and thresh. However, deep treatment produces a large amount of straw debris, so it is advantageous for varieties with no delayed spikes to use shallower treatment than usual.

Further, JP-A-53-86330 also does not correspond to a grain culm having many delayed ears or a grain culm having no delayed ears depending on the variety.

However, the present invention, the mowing unit 17 for mowing the grain culm, the threshing unit 19 for threshing the grain culm pruned by the mowing unit 17, and the transfer take-over unit 18 from the mowing unit 17 to the threshing unit 19, A handle which can be moved forward and backward in the direction of the cuttings by operating the stocker side sensor 10 and the tip side sensor 11 which are provided in parallel in the direction of the cuttings of the grain culvert provided in the transfer and transfer section 18 and the both sensors. In the one having the depth adjusting unit 20, the handling depth adjusting unit 20
Is provided with a switching unit 16 capable of switching between shallow handling 13, deep handling 15 and standard use 14, and when the switching unit 16 is switched to shallow handling 13, the tip is on the stock side sensor 10. If not reached, the tip is moved forward in the direction of the culm and the tip is the sensor on the stock side.
When the tip reaches 10, the tip is moved forward in the direction of the culm, and when the switching unit 16 is switched to the deep-handle 15, the tip is advanced in the direction of the ears when the tip has not reached the tip side sensor 11. When moving the tip reaches the tip side sensor 11, the tip is moved forward in the direction of the stem, and when the switching unit 16 is switched to the standard 14, the tip is the stock side sensor 10 and the tip side. Since it is a handle depth adjustment device in the combine that repeats forward and backward movement in the direction of the stem with the sensor 11, when the switching unit 16 is switched to the shallow handling 13, the tip of the tip is the sensor on the stock side.
When it does not reach 10, the tip is moved forward in the direction of the culm, and when the tip reaches the plant side sensor 10, the tip is moved backward in the direction of the culm. When threshing is possible and the switching unit 16 is switched to the deep handling 15, when the tip does not reach the tip side sensor 11, the tip is moved forward in the direction of the culm, and when the tip reaches the tip side sensor 11, the tip is culled. Since it moves backward in the direction of the body, threshing of varieties with many delayed ears can be performed, and when switching section 16 is switched to standard 14
Since the tip of the head repeats forward and backward movements in the direction of the culm between the root side sensor 10 and the head side sensor 11, normal threshing can be performed.

The present invention also relates to a mowing unit 17 for mowing grain culms, and the mowing unit 17
Threshing section 19 for threshing the grain culms cut by, the transfer takeover section 18 from the reaping section 17 to the threshing section 19, and the juxtaposed direction of the grain culms provided in the transfer takeover section 18 are arranged side by side. In the one having the stocking depth side sensor 10 and the tip side sensor 11 and the handling depth adjusting section 20 which can be operated by the both sensors to move the tips forward and backward in the culm direction, in the handling depth adjusting section 20, A switching unit 16 that can switch between shallow handling 13, deep handling 15 and standard 14 is provided, and when the switching unit 16 is switched to shallow handling 13,
When the tip has not reached the root side sensor 10, the tip is moved forward in the barrel direction and when the tip reaches the root sensor 10, the tip is moved backward in the barrel direction, and the switching unit 16 When the tip is not reaching the tip side sensor 11, the tip is moved forward in the culm direction when the tip is not reaching the tip side sensor 11, and when the ears reach the tip side sensor 11, the ears are moved in the tip direction. When it is moved backward and the switching unit 16 is switched to the standard 14, the tip is treated in a combine that repeats forward and backward movements in the direction of the stem between the stock origin side sensor 10 and the tip side sensor 11. In the depth adjusting device, the output interval of the controller 12 when advancing the tip in the direction of the culm in the state where the ears do not reach the root side sensor 10 and when the ears reach the tip side sensor 11 and move backward in the direction of the culm Keep it short, and the tip is the sensor on the stock side Since the output interval of the controller 12 when moving the tip backward in the direction of the culm in the state of reaching 10 is the handle depth adjusting device in the combine, so until the tip reaches both sensors 10, 11. Since the target state has not been reached yet, the output interval of the controller 12 is made short and adjusted quickly, and when the tip reaches the stock side sensor 10, it is already in the target state, so the controller after that The 12 output intervals are made longer to reduce unnecessary vibration.
