An embodiment of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a body frame, 2 a traveling device, 3 a threshing device provided above the traveling device 2, 4 a reaping device, and 5 a side portion of the threshing device 3. Glen tanks, 5 are Glen tanks, and 6 is a control unit.
The reaping device 4 includes a plurality of weeding devices 7 arranged at intervals in the left-right direction, a plurality of pulling devices 8 provided at the rear of each weeding device 7, and the like. Behind the pulling device 8, there are provided a cutting blade 10 for cutting the stock of the culm and a culm conveying device H for conveying the harvested culm. The configuration of the cereal conveying device H is arbitrary, 11 is a rake device behind the pulling device 8, 12 is a stock conveying device, 13 is a tip conveying device, and 18 is a cereal that supplies cereal to the threshing device 3. It is a cocoon supply transport device

A pair of left and right pulling devices 8 are provided in front of the scraping device 11. The left and right pulling devices 8 hang a pulling chain 25 in which a plurality of pulling lugs 24 are attached to a driving wheel 21, a lower outer driven wheel 22, and a lower inner driven wheel 23 provided on the pulling frame 20 at a predetermined interval. The pulling case 26 is provided on the front side of these drive mechanisms.
The pulling device 8 forms a lateral movement part Y in which the pulling lug 24 linearly moves laterally, and the front end portion of the scraping device 11 is in the vicinity of the outer end of the pulling lug 24 lateral movement part Y in the front view or Place inside.
That is, two lower outer driven wheels 22 and a lower inner driven wheel 23 are provided at the lower part of the pulling device 8, and a pulling chain 25 having a plurality of pulling lugs 24 is wound around the lower outer driven wheel 22 and the lower inner driven wheel 23. As a result, the pulling lug 24 is formed between the two lower outer driven wheels 22 and the lower inner driven wheel 23 in a laterally moving portion Y where the pulling lug 24 linearly moves laterally.

Therefore, the linear movement part when the pulling lug 24 moves in the lower part of the pulling case 26 is lengthened, and the width of the grain that can be raised between the left and right pulling devices 8 is widened.
The weeding device 8 is provided outside the movement locus of the pulling lug 24 of the pair of left and right pulling devices 8, and the pulling device 8 is positioned outside the left and right crawlers 30 of the traveling device 2.
That is, in a small combine, the harvesting width of the harvesting device 4 is narrower than the distance between the left and right crawlers 30, and it becomes difficult to perform the half-slicing operation where uncut grain culms exist on the left and right outer sides of the machine body. The pulling device 8 is positioned outside the left and right crawlers 30 of the traveling device 2, and has a so-called full-cutting configuration in which the pulling device 8 causes the pulling device 8 to cut and convey the cereals that have been weeded.
The pitch of the pulling lugs 24 of the pulling device 8 is configured such that when the lateral movement between the lower outer driven wheel 22 and the lower inner driven wheel 23 is laterally moved, the plurality of pulling lugs 24 are moved.
Therefore, the raising posture of the cereal by the raising lug 24 is made favorable.

The scraping device 11 is configured to bring the front end of the scraping device 11 close to the back surface of the pulling device 8.
In other words, the scraping lug 35 of the scraping device 11 passes through the vicinity of the rear of the pulling frame 20 of the pulling device 8.
Therefore, immediately after the culm caused by the pulling lug 24 of the pulling device 8, the scraping lug 35 of the scraping device 11 rakes in, and the middle part of the gruel hangs down, and the tip is handled by the pulling lug 24 of the pulling device 8. The head loss that occurs is suppressed, and the withdrawal of cereals is prevented.
The pulling device 8 attaches the base portion of the pulling frame 20 to the weeding rod 36 via the mounting rod 37. When the movement trajectory of the scraping lug 35 of the scraping device 11 faces the front side of the mounting rod 37, the working area of the scraping device 11 is brought closer to the rear side of the pulling device 8, and the scraping lug 35 Squeezes the raised cereal meal and improves the conveying posture.
Further, the trajectory of the scraping lug 35 of the scraping device 11 is behind the pulling lug 24 that moves in the lower portion of the pulling device 8 and is substantially equal to the extension line L on the lower rear surface of the pulling frame 20 of the pulling device 8. Or if it positions ahead, the operation area of the picking-up apparatus 11 will be made to approach the rear side of the pulling apparatus 8, and a conveyance attitude | position will be made favorable.

A pair of left and right scraping devices 11 are provided. The trajectory of the scraping lugs 35 of the left and right scraping devices 11 is configured to be inclined substantially equally to the left and right with reference to the central weeding device 7C between the left and right.
That is, the scraping lug 35 scrapes the cereals inward as it reaches the rear side, and makes the angle toward the inner side substantially equal to the left and right.
Therefore, the transfer from the raising by the pulling device 8 to the scratching by the scratching device 11 becomes smooth.
Further, the angle formed by the working-side linear portion of the scraping device 11 and the reaping device 4 front-rear direction is configured to be approximately 45 degrees or less than 45 degrees (FIG. 7).
For this reason, the culm is conveyed while the culm transporting direction by the scraping device 11 approaches the center of the reaping device 4.
The scraping device 11 is wound around a driving belt 40 and a front roller 41 with a scraping belt 42 having a scraping lug 35, and the front roller 41 has a lower outer driven wheel 22 and a lower inner driven wheel of the pulling device 8. 23, it is arranged inside the lower outer driven wheel 22 (FIG. 5).

Therefore, the working area of the scraping lug 35 of the scraping device 11 can be approached to the rear side of the pulling device 8, the transfer from the pulling to the scraping can be performed well, and the middle part of the cereal can be hung down. It is possible to suppress the disturbance of the conveying cereal and the clogging of the cereal, thereby improving the conveying performance.
That is, the scraping lug 35 scrapes the cereal in the shape of “C” in a plan view, and therefore when the scraping lug 35 moves from the scratching start position to the rear side, the pulling lug 35 from the pulling device 8. However, in this application, since the front roller 41 is disposed on the inner side of the lower outer driven wheel 22, the scraper 11 does not act on the rear side of the pulling device 8. The working area of the pull-in lug 35 is brought closer to the rear side of the pulling device 8, the dead space where the scraping device 11 does not act on the rear side of the pulling device 8 is reduced, and the conveyance performance is improved.

Further, the rotation center of the front roller 41 or the take-in lug 35 may be positioned behind a position that is inside the outer edge of the pulling case 26 of the pulling device 8.
Note that the rotation center G of the take-up lug 35 refers to a place where the take-up lug 35 is reversed from the non-operation area to the operation area, and this inversion position is located on the inner side of the outer edge of the pulling case 26 of the pulling device 8. It is located behind the position.
In addition, behind the lower outer driven wheel 22 and the guide 43 and the pulling case 26,
The center of rotation of the front roller 41 or the take-up lug 35 may be disposed.
In other words, the front roller 41 of the scavenging device 11 is positioned behind the portion where the pulling lug 24 between the lower outer driven wheel 22 and the lower inner driven wheel 23 moves in a horizontal straight line (FIG. 5).
Therefore, the grain lug 35 located behind the part that moves in a horizontal straight line is raked in the grain straw attracted by the pulling lug 24 that moves in a horizontal straight line from the outside stock to suppress the hanging of the grain straw. To improve the transport posture.

The movement trajectory of the front end of the take-up lug 35 is approximately the same height as the lower end of the pulling case 26 of the pulling device 8 (FIG. 5).
For this reason, the working area of the take-up lug 35 can be brought closer to the working area of the pulling lug 24 of the pulling device 8, and in particular, the conveying posture of the fallen cereal can be improved.
That is, in the side view, the scraping lug 35 is inclined so as to be on the upper side as it goes rearward and moves rearwardly upward. Therefore, when the scraping lug 35 moves rearward from the scraping start position, the scraping lug 35 is moved. However, in this application, the movement locus of the front end of the take-up lug 35 is referred to as the raising case of the pulling device 8. Since it is made into the height substantially the same as the lower end of 26, the rake lug 35 acts from the part under the grain candy, makes a corn straw conveyance posture favorable, and improves conveyance performance.
Moreover, it arrange | positions so that the movement locus | trajectory of the front end of the picking lug 35 may become below the rotation center of the raising lug 24 of the raising device 8 (for example, FIG. 5).

Therefore, since the working area of the raking lug 35 is below the rotation center of the pulling lug 24 of the pulling device 8, the raking lug 35 acts from the lower part of the wheat straw to change the grain conveying posture. Improve the conveyance performance.
In this case, the rotation center of the pulling lug 24 of the pulling device 8 refers to a location where the pulling lug 24 changes the moving direction from linear movement to upward movement, and the center of the lower outer driven wheel 22 and the lower inner driven wheel 23. Become.
In the weeding device 7, the tip T of the left weeding device 7L located on the left side of the reaping device 4 and the tip T of the right weeding device 7R located on the right side are respectively movable to the left and right. To do.
When the tip T of the left weeding device 7L and the tip T of the right weeding device 7R located on the right side are moved in a direction approaching each other, two cereal grains are introduced between them, and the left weeding device When the tip L of the 7L and the tip T of the right weeding device 7R located on the right side are moved away from each other, four rows of cereals are introduced between them.

Although the left-right moving configuration of the tip T of the weeding device 7 is arbitrary, for example, the weeding device 7 is fixed to the tip of the mounting rod 50 in the front-rear direction, and the base portion of the mounting rod 50 is attached to the weeding rod 36. Attached to the vertical axis 51 so as to be rotatable. The left and right intermediate portions of the arm 52 are fixed to the vertical axis 51, and the operation transmission member 53 such as a wire is connected to both ends of the arm 52 (FIG. 7). The operation transmission member 53 is an operation provided in the control unit 6. Connect to the lever 54 (FIGS. 2 and 10).
When the weeding device 7 operates the operation lever 54 provided in the control unit 6, the tip T moves to the left and right around the center of the vertical axis 51.
Therefore, the cutting width can be changed not only by changing the tip T of the weeding device 7 but also by moving the tip T of the weeding device 7 in and out depending on the working conditions such as the fallen cereal.

Further, the distance between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is narrower than the entire cutting width of the cutting blade 10 when closed, and wider than the entire cutting width of the cutting blade 10 when opened. It is set as a structure (FIG. 6, FIG. 7).
Therefore, at the time of double cutting with the left and right weeding devices 7 closed, the interval between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is narrower than the entire cutting width of the cutting blade 10. Then, when four-row cutting is performed with the left and right weeding devices 7 spread, the interval between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is set to the entire cutting blade 10. The cutting operation is performed with a width wider than the cutting width (FIG. 7).
In the above case, when the tip T of the right weeding device 7 is expanded in the N-row mowing device 4, two cereal grains are contained between the right weeding device 7 and the adjacent weeding device 7. “N + 1” reaping is possible, and two cereal grains are placed between the left weeding device 7 and the adjacent weeding device 7, and “N + 2” reaping is possible.

For example, in the embodiment of FIG. 5 and FIG. 6, when two cuttings are performed, for example, when the tip T of the right weeding device 7 is widened, two cereal grains are placed between the right weeding device 7 and the central weeding device 7. If a cocoon enters and it cuts into 3 lines, and if the front-end | tip T of the weeding device 7 on the left side is expanded, it will change to 4 lines.
In the embodiment of FIG. 12, for example, three-row cutting is changed to four-row cutting by widening the tip T of the right weeding device 7 to make four-row cutting, and widening the tip T of the left-side weeding device 7.
In the embodiment of FIG. 13, for example, the four-row cutting is changed to a six-row cutting when the tip T of the right weeding device 7 is widened to a five-row cutting and the tip T of the left-side weeding device 7 is expanded.
In the embodiment of FIG. 14, for example, widening the tip T of the right weeding device 7, spreading two cereals between the adjacent weeding device 7, and cutting the 5 rows into 6 rows. When the tip T of the weeding device 7 is widened, it is changed to seven-row cutting.
In the embodiment of FIG. 15, 6-row cutting is changed to 8-row cutting when the tip T of the right weeding device 7 is widened to form 7-row cutting, and when the tip T of the left-side weeding device 7 is expanded.
Therefore, the adaptability to the field between irregular stripes can be improved.

In the embodiment of FIG. 16, seven-row cutting is changed to, for example, eight-row cutting by widening the tip T of the right weeding device 7, and nine-row cutting when the tip T of the left-side weeding device 7 is expanded.
In this case, the tip T of the right weeding device 7 is positioned inside the outermost end of the right crawler 30 in a state where the tip T is positioned at the inner position.
Therefore, the collision of the weeding device 7 at the time of turning is prevented.
Moreover, since the width | variety of the cutting device 4 becomes narrow, loading to a truck bed etc. becomes easy.
In this case, the tip T of the left weeding device 7 is positioned outside the outermost end of the right crawler 30 in a state where the tip T is positioned at the inner position.
Therefore, the cutting width of the cutting device 4 is made wider than the distance between the left crawlers 30 to prevent the uncut wheat straw from being stepped on.
12 to 16, the left and right pulling devices 8 are provided with a lower outer driven wheel 22 and a lower inner driven wheel 23 so that the pulling lug 24 moves laterally. The pulling device 8 is provided with a single driven wheel 22A in the lower portion, and the pulling lug 24 is configured to reverse upwardly about the driven wheel 22A.
FIG. 17 shows another embodiment of the reaping device 4. The right pulling device 8 is provided with a lower outer driven wheel 22 and a lower inner driven wheel 23 so that the pulling lug 24 moves laterally. The left pulling device 8 is provided with one driven wheel 22A in the lower portion, the pulling lug 24 is configured to reverse upwardly moving around the driven wheel 22A, and the left weeding device 7 is cut into two inner strips. It is set as the structure changed to outer 3 line cutting.
Therefore, it is possible to work efficiently by switching to 2-row cutting or 3-row cutting according to the working conditions.

(Operation of Example)
The machine is run, weeded by the weeding device 7, the weed cereal is raised by the pulling device 8, and the root of the caused cereal is cut by the cutting blade 10 while being scraped by the scraping device 11. The harvested corn straw is conveyed by the stock source conveying device 12 and the tip conveying device 13 of the corn straw conveying device H.
The cereals conveyed by the cereal conveying device H are taken over by the cereal supply / conveying device 18 that supplies the threshing device 3 to the threshing device 3 and threshed during the conveyance by the cereal supply / conveying device 18.
The pulling device 8 is provided in a pair of left and right in front of the scraping device 11, and the left and right pulling devices 8 include a driving wheel 21 provided on the pulling frame pulling frame 20, a pair of lower outer driven wheels 22 and a lower inner driven wheel on the lower portion. Since the pulling chain 25 provided with the pulling lug 24 is hung around the driving wheel 23, the pulling lug 24 moves in the lateral direction between the lower outer driven wheel 22 and the lower inner driven wheel 23, and the left and right pulling devices 8. The width of the grains that can be raised between them is widened.

In this case, the weeding device 8 is provided outside the movement trajectory of the pulling lug 24 of the pair of left and right pulling devices 8, but the pulling device 8 is positioned outside the left and right crawlers 30 of the traveling device 2. The cutting width of the cutting device 4 is made wider than the distance between the crawlers 30 to cope with the so-called full cutting.
The scraping device 11 is configured to bring the front end of the scraping device 11 closer to the back surface of the pulling device 8.
In other words, the scraping lug 35 of the scraping device 11 passes through the vicinity of the rear of the pulling frame 20 of the pulling device 8.
Therefore, immediately after the culm caused by the pulling lug 24 of the pulling device 8, the scraping lug 35 of the scraping device 11 rakes in, and the middle part of the gruel hangs down, and the tip is handled by the pulling lug 24 of the pulling device 8. The head loss that occurs is suppressed, and the withdrawal of cereals is prevented.

The pulling device 8 attaches the base of the pulling frame 20 to the weeding rod 36 via the mounting rod 37 and faces the movement locus of the scraping lug 35 of the scraping device 11 at a position ahead of the mounting rod 37. The working area of the scraping device 11 is brought closer to the rear side of the pulling device 8, and the scraping lug 35 makes the pulling cereal rice cake scrape good and makes the conveying posture good.
Further, the trajectory of the scraping lug 35 of the scraping device 11 is behind the pulling lug 24 that moves in the lower portion of the pulling device 8 and is substantially equal to the extension line L on the lower rear surface of the pulling frame 20 of the pulling device 8. Or since it is located in the front, the working area of the scraping device 11 can be brought closer to the rear side of the pulling device 8 to improve the conveying posture.
A pair of left and right take-up devices 11 are provided, and the movement trajectory of the take-up lugs 35 of the left and right take-up devices 11 is inclined substantially equally with respect to the left and right middle weeding device 7C. The transfer from the pulling-up by 8 to the scraping by the scraping device 11 becomes smooth.

In addition, since the angle formed by the working side linear portion of the scraping device 11 and the front-rear direction of the reaping device 4 is configured to be approximately 45 degrees or smaller than 45 degrees, the culm transport direction by the rake device 11 is Carry the cereal while moving to the center.
The scraping device 11 is wound around a driving belt 40 and a front roller 41 with a scraping belt 42 having a scraping lug 35, and the front roller 41 is connected to the lower outer driven wheel 22 and the lower inner driven wheel 23 of the pulling device 8. Of these, since the lower outer driven wheel 22 is disposed on the inner side, the working area of the scraping lug 35 of the scraping device 11 can be approached to the rear side of the pulling device 8, so It is possible to improve the delivery performance by improving the delivery performance to the intermediate part of the cereal, preventing the hanging of the middle part of the cereal, preventing the disturbance of the cereal and clogging of the cereal.

That is, the scraping lug 35 scrapes the cereal in the shape of “C” in a plan view, and therefore when the scraping lug 35 moves from the scratching start position to the rear side, the pulling lug 35 from the pulling device 8. However, in this application, since the front roller 41 is disposed on the inner side of the lower outer driven wheel 22, the scraper 11 does not act on the rear side of the pulling device 8. The working area of the pull-in lug 35 is brought closer to the rear side of the pulling device 8, the dead space where the scraping device 11 does not act on the rear side of the pulling device 8 is reduced, and the conveyance performance is improved.
In other words, the front roller 41 of the scraping device 11 is positioned behind the portion where the pulling lug 24 between the lower outer driven wheel 22 and the lower inner driven wheel 23 moves in a horizontal straight line. The grain lug 35 that is positioned behind the part that moves in a horizontal straight line is raked in by the pulling lug 24 that moves laterally inward from the stock, and the conveying posture is suppressed by suppressing the hanging of the grain straw. Make good.

Since the movement locus of the front end of the take-up lug 35 is substantially the same as the lower end of the raising case 26 of the pulling device 8, the working area of the picking lug 35 is brought close to the working area of the pulling lug 24 of the pulling device 8. In particular, it will improve the conveying posture of the overlaid cereal.
That is, in the side view, the scraping lug 35 is inclined so as to be on the upper side as it goes rearward and moves rearwardly upward. Therefore, when the scraping lug 35 moves rearward from the scraping start position, the scraping lug 35 is moved. However, in this application, the movement locus of the front end of the take-up lug 35 is referred to as the raising case of the pulling device 8. Since it is made into the height substantially the same as the lower end of 26, the rake lug 35 acts from the part under the grain candy, makes a corn straw conveyance posture favorable, and improves conveyance performance.

In addition, since the movement trajectory of the front end of the take-up lug 35 is arranged to be below the rotation center of the pull-up lug 24 of the pulling device 8, the working area of the pick-up lug 35 is that of the pulling device 8. Since it becomes below the rotation center of the pulling lug 24, the take-up lug 35 acts from the lower part of the corn straw to improve the corn straw conveying posture and improve the conveying performance.
Among the weeding devices 7, the tip T of the left weeding device 7L located on the left side of the cutting device 4 and the tip T of the right weeding device 7R located on the right side are configured to be movable to the left and right, respectively. When the tip T of the weeding device 7L and the tip T of the right weeding device 7R located on the right side are moved in a direction approaching each other, two cereal grains are introduced between them, and the left weeding device 7L When the tip T of the right side and the tip T of the right weeding device 7R located on the right side are moved away from each other, four rows of cereals are introduced between them. Thus, not only the tip T of the weeding device 7 but also the cutting width can be changed only by moving the tip T of the weeding device 7 in and out.
When the weeding device 7 operates the operation lever 54 provided in the control unit 6, the tip T moves to the left and right around the center of the vertical axis 51.

Further, the distance between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is narrower than the entire cutting width of the cutting blade 10 when closed, and wider than the entire cutting width of the cutting blade 10 when opened. Because of the configuration, when performing two-row cutting with the left and right weeding devices 7 closed, the interval between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is set to the overall cutting of the cutting blade 10. When performing 4-row cutting with the width of the weeding device 7 narrower than that of the width, the spacing between the tip T of the left weeding device 7L and the tip T of the right weeding device 7R is defined as the cutting blade. The cutting operation is performed with a width wider than the total cutting width of 10.
In the above case, when the tip T of the right weeding device 7 is expanded in the N-row mowing device 4, two cereal grains are contained between the right weeding device 7 and the adjacent weeding device 7. “N + 1” reaping is possible, and two cereal grains are placed between the left weeding device 7 and the adjacent weeding device 7, and “N + 2” reaping is possible.
For example, in the embodiment shown in FIGS. 5 and 6, when two cuttings are performed, for example, when the tip T of the right weeding device 7 is widened, two cereal grains are placed between the right weeding device 7 and the central weeding device 7. Enters 3 cuts, and when the tip T of the left weeding device 7 is widened, it is changed to 4 cuts.

In the embodiment of FIG. 12, for example, three-row cutting is changed to four-row cutting by widening the tip T of the right weeding device 7 to make four-row cutting, and widening the tip T of the left-side weeding device 7.
In the embodiment of FIG. 13, for example, the four-row cutting is changed to a six-row cutting when the tip T of the right weeding device 7 is widened to a five-row cutting and the tip T of the left-side weeding device 7 is expanded.
In the embodiment of FIG. 14, for example, widening the tip T of the right weeding device 7, spreading two cereals between the adjacent weeding device 7, and cutting the 5 rows into 6 rows. When the tip T of the weeding device 7 is widened, it is changed to seven-row cutting.
In the embodiment of FIG. 15, 6-row cutting is changed to 8-row cutting when the tip T of the right weeding device 7 is widened to form 7-row cutting, and when the tip T of the left-side weeding device 7 is expanded.
In the embodiment of FIG. 16, seven-row cutting is changed to, for example, eight-row cutting by widening the tip T of the right weeding device 7, and nine-row cutting when the tip T of the left-side weeding device 7 is expanded.
In this case, the tip T of the right weeding device 7 is positioned inside the outermost end of the right crawler 30 in a state where the tip T is positioned at the inner position.
Therefore, the collision of the weeding device 7 at the time of turning is prevented.

Moreover, since the width | variety of the cutting device 4 becomes narrow, loading to a truck bed etc. becomes easy.
In this case, the tip T of the left weeding device 7 is positioned outside the outermost end of the right crawler 30 in a state where the tip T is positioned at the inner position. Also, the cutting width of the mowing device 4 is widened, and the uncut rice cake is prevented from being stepped on.
FIG. 17 shows another embodiment of the mowing device 4 in which the right pulling device 8 is provided with a lower outer driven wheel 22 and a lower inner driven wheel 23 so that the pulling lug 24 moves laterally. The pulling device 8 on the left side is provided with one driven wheel 22A at the bottom, and the pulling lug 24 is configured to reversely move upward around the driven wheel 22A.
