Description

combine

[0001] The present invention relates to a combine harvester for harvesting planted cereal stalks.

[0002] A known combine harvester is disclosed in Patent Document 1. The combine harvester disclosed in Patent Document 1 includes a cutting unit that cuts culms planted in a field (planted culms) and a divider (grass dividing body) that divides the planted culms to the left and right. The cutting unit is provided with a dividing guide that guides the planted culms divided by the divider.

[0003] Japanese Patent Publication No. 2019-141017

[0004] The harvesting operation using the combine harvester described above is performed by aligning the front end of the divider near the side of the planted culms in rows and running the traveling machine body so that the front end passes near the side of the planted culms. Therefore, during harvesting, the operator needs to check the position of the divider relative to the planted culms from the driver's seat.

[0005] However, when performing harvesting operations using a conventional combine harvester as described above, the planted culms may fall over (lean) above the divider, making it difficult to confirm the position of the divider relative to the planted culms.

[0030] A preferred embodiment of a combine harvester according to the present invention will be described below. The combine harvester 1 of this embodiment is a head-feeding combine harvester. Figures 1 to 3 are diagrams showing the overall configuration of the combine harvester 1. In this embodiment, the direction of travel of the combine harvester 1 in a working state (harvesting) is defined as the forward direction. In the figures, the direction indicated by arrow F is the forward direction, and the direction indicated by arrow B is the backward direction. Furthermore, the direction indicated by arrow L is the leftward direction, and the direction indicated by arrow R is the rightward direction.

[0031] The combine harvester 1 includes a traveling machine body 2 having a machine body frame 3 and traveling devices 4. The traveling devices 4 are arranged below the machine body frame 3. The traveling devices 4 are composed of a pair of left and right crawler traveling devices. A cabin 5 is mounted on the traveling machine body 2. The cabin 5 is arranged offset to either the left or right side (in this embodiment, the right side) from the center of the width of the traveling machine body 2. A driver's seat 6 is provided inside the cabin 5. An engine (not shown) is arranged below the driver's seat 6.

[0032] The combine harvester 1 includes a reaping unit 8 that reaps crops (planted culms), a threshing device 9 that threshers the crops reapsed by the reaping unit 8, and a grain tank 10 that stores the crops threshed by the threshing device 9. A grain discharge device 7 that discharges the grains in the grain tank 10 is connected to the top of the grain tank 10.

[0033] The reaping unit 8 is provided at the front of the traveling body 2. The reaping unit 8 is located in front of the cabin 5 (including the left front). The reaping unit 8 can reap multiple rows of planted culms. In this embodiment, the reaping unit 8 can reap seven rows of planted culms. In other words, the reaping unit 8 is configured for seven-row reaping. However, the reaping unit 8 is not limited to seven-row reaping specifications, and may be configured to reap fewer than seven rows of planted culms, or may be configured to reap more than seven rows of planted culms.

[0034] The reaping unit 8 has a divider (grass dividing tool) 11 that divides the base-side portion of the planted culm. The divider 11 is supported by a grass dividing frame 12 (see Figures 1, 4, etc.) located below the reaping unit 8. The grass dividing frame 12 extends in the front-to-rear direction below the reaping unit 8.

[0035] As shown in Figures 2 to 5, a plurality of dividers 11 are provided at intervals in the left-right direction. Rows of planted culms (row-planted) are guided between adjacent dividers 11, 11. The number of dividers 11 is determined by the specifications of the reaping unit 8. In this embodiment, where the reaping unit 8 is configured for seven-row reaping, the number of dividers 11 is eight.

[0036] Hereinafter, the eight dividers 11 will be referred to as the first divider 111, the second divider 112, the third divider 113, the fourth divider 114, the fifth divider 115, the sixth divider 116, the seventh divider 117, and the eighth divider 118, from right to left.

[0037] The eight dividers include large dividers and small dividers. As shown in Figures 4 and 5, the first divider 111, the third divider 113, the fifth divider 115, the sixth divider 116, and the eighth divider 118 are large dividers. The second divider 112, the fourth divider 114, and the seventh divider 117 are small dividers.

[0038] The front ends of the large dividers (first divider 111, third divider 113, fifth divider 115, sixth divider 116, and eighth divider 118) are located further rearward than the front ends of the small dividers (second divider 112, fourth divider 114, and seventh divider 117). The height of the top surfaces of the large dividers is higher than the height of the top surfaces of the small dividers.

[0039] The configuration of the large dividers will be described below. First, the configuration of the first divider 111, which is located on the farthest side (right side) in the left-right direction, will be described with reference to Figures 6 to 12. As shown in Figures 7, 9, and 10 to 12, the first divider 111 has a divider body 13 and a support plate 14 that supports the divider body 13 from below.

[0040] 6 and 8, the divider body 13 has a front portion 13a that widens toward the rear and a rear portion 13b that narrows toward the rear. The front end of the front portion 13a (the front end of the divider body 13) is formed at an acute angle.

[0041] The upper surface of the divider body 13 constitutes the upper surface 11a of the divider 11 (first divider 111). As shown in Figures 10 and 11, the upper surface of the divider body 13 (the upper surface 11a of the divider 11) is inclined so as to gradually rise toward the rear in a side view. The upper surface of the divider body 13 (the upper surface 11a of the divider 11) is curved in an arc shape that convexly faces downward toward the rear.

[0042] As shown in Figures 7, 9, etc., the support plate 14 is disposed with its plate surface facing the left-right direction. The support plate 14 is fixed to the underside of the divider body 13. The support plate 14 extends in the front-rear direction along the center of the width direction (left-right direction) of the divider body 13. As shown in Figure 11, the front end of the support plate 14 is formed at an acute angle in a side view. However, the frontmost end of the support plate 14 is rounded. The front end 14a of the support plate 14 protrudes further forward than the front end 13c of the divider body 13.

[0043] As shown in Figures 10 to 12, through holes are formed in the support plate 14. The through holes include a first through hole 14b and a second through hole 14c. The first through hole 14b and the second through hole 14c penetrate the support plate 14 in the left-right direction. The first through hole 14b and the second through hole 14c are formed in the front part of the support plate 14 (the front part of the divider 11). The first through hole 14b is formed further forward in the front-to-rear direction than the front end of the divider main body 13. The mounting portion 80a of the grass dividing guide 80, which will be described later, is engaged in the first through hole 14b.

[0044] The second through-hole 14c is formed rearward and below the first through-hole 14b. The position of the second through-hole 14c in the front-rear direction is substantially the same as the position of the front end of the divider body 13 in the front-rear direction. A hook for attaching a protective cover (not shown) that covers the front end of the divider 11 is engaged in the second through-hole 14c.

[0045] As shown in Figures 9 to 12, the support plate 14 is attached to the grass dividing frame 12. The grass dividing frame 12 is formed from a round pipe. A flat base plate 15 is fixed to the front upper surface of the grass dividing frame 12. The support plate 14 is attached to the base plate 15 via a mounting structure 16. The mounting structure 16 is composed of a mounting plate 17, a support member 18, and a connecting member 19. The mounting plate 17, support member 18, and connecting member 19 are integrated.

[0046] The mounting plate 17 is disposed with its plate surface facing the left-right direction. The mounting plate 17 is attached to the support plate 14 by a fixture consisting of a bolt BL1 and a nut NT1. As shown in FIG. 12 , the support plate 14 has two through holes 14d through which the bolts BL1 are inserted. The mounting plate 17 also has two through holes 17a through which the bolts BL1 are inserted. The two through holes 14d and the two through holes 17a are formed side by side in the front-to-rear direction. The two through holes 14d formed in the support plate 14 are circular holes. Of the two through holes 17a formed in the mounting plate 17, the front through hole 17a is a circular hole, and the rear through hole 17a is an elongated hole extending in an arc shape from a rear-lower side to a front-upper side.

[0047] The support member 18 is fixed to the lower part of the mounting plate 17 and supports the mounting plate 17. As shown in Figures 10 and 11, the support member 18 is disposed in front of the grass dividing frame 12 and extends forward. The front part of the support member 18 is formed in a conical shape that tapers toward the front. The rear part of the support member 18 is formed in a cylindrical shape.

[0048] As shown in Figures 10 to 12, the connecting member 19 connects the mounting plate 17 and the support member 18. The front part of the connecting member 19 is fixed to the rear part of the mounting plate 17. The rear part of the connecting member 19 is attached to the base plate 15 by bolts BL2. The connecting member 19 has a plurality of through holes (first hole 19a, second hole 19b, third hole 19c) through which the bolts BL2 can be inserted. The first hole 19a and the second hole 19b are arranged side by side in the front-to-rear direction. The third hole 19c is arranged to the right rear of the second hole 19b.

[0049] 12, a plurality of through holes (fourth hole 15a, fifth hole 15b, sixth hole 15c) through which the bolts BL2 can be inserted are formed in the base plate 15. The fourth hole 15a, fifth hole 15b, and sixth hole 15c are arranged in a line in the front-rear direction.

[0050] Although not shown in the figure, the grass division frame 12 has multiple screw holes (first screw hole, second screw hole, third screw hole) into which the bolt BL2 can be screwed. The first screw hole, second screw hole, and third screw hole are arranged in a line in the front-to-back direction. The first screw hole is located in a position overlapping with the fourth hole 15a. The second screw hole is located in a position overlapping with the fifth hole 15b. The third screw hole is located in a position overlapping with the sixth hole 15c.

[0051] The connecting member 19 is attached to the grass dividing frame 12 by inserting a bolt BL2 through the through holes (first hole 19a, second hole 19b, third hole 19c) formed in the connecting member 19 and the through holes (fourth hole 15a, fifth hole 15b, sixth hole 15c) formed in the base plate 15, and screwing the bolt BL2 into the screw hole formed in the grass dividing frame 12. In addition, the support plate 14 is attached to the mounting plate 17 by inserting a bolt BL1 through the through hole 17a formed in the mounting plate 17 and the through hole 14d formed in the support plate 14, and screwing in a nut NT1. This attaches the divider 11 to the grass dividing frame 12.

[0052] 4 and 5, the eighth divider 118, which is located on the other side (left side) of the multiple large dividers in the left-right direction, is configured symmetrically to the first divider 111 across the widthwise center line of the traveling body 2. The configuration of the eighth divider 118 is the same as the configuration of the first divider 111, except for the differences resulting from the eighth divider 118 being symmetrical to the first divider 111 across the widthwise center line of the traveling body 2.

[0053] Of the large dividers, the third divider 113, fifth divider 115, and sixth divider 116 have a divider body and a support plate that supports the divider body from below, similar to the first divider 111. The shapes of the divider bodies of the third divider 113, fifth divider 115, and sixth divider 116 are the same as the shape of the divider body 13 of the first divider 111. The shapes of the support plates of the third divider 113, fifth divider 115, and sixth divider 116 are slightly different from the shape of the support plate 14 of the first divider 111, but a detailed description of the shapes will be omitted.

[0054] As shown in Figures 4, 5, 13, and 14, the reaping unit 8 includes a raising unit 29 that raises the planted stalks divided by the divider 11. The raising unit 29 has a plurality of raising devices 30. The plurality of raising devices 30 are arranged side by side in the left-right direction. In this embodiment, there are seven raising devices 30. Hereinafter, the seven raising devices 30 will be referred to, from right to left, as a first raising device 31, a second raising device 32, a third raising device 33, a fourth raising device 34, a fifth raising device 35, a sixth raising device 36, and a seventh raising device 37.

[0055] As shown in Figures 3 to 5, the raising unit 29 has a plurality of conveying paths 50 through which the planted stalks raised by the raising devices 30 pass. The conveying paths 50 are formed between adjacent raising devices 30 in the left-right direction. In this embodiment, there are four conveying paths 50. Hereinafter, the four conveying paths 50 will be referred to as a first conveying path 51, a second conveying path 52, a third conveying path 53, and a fourth conveying path 54, from right to left.

[0056] 4 and 5, the first transport path 51 is formed between the first raising device 31 and the second raising device 32. The second transport path 52 is formed between the third raising device 33 and the fourth raising device 34. The third transport path 53 is formed between the fifth raising device 35 and the sixth raising device 36. The fourth transport path 54 is formed between the sixth raising device 36 and the seventh raising device 37.

[0057] To explain the position of the transport path 50 in terms of its positional relationship with the divider 11 in the left-right direction, the transport path 50 is formed between one divider and another divider that are adjacent to each other in the left-right direction. More specifically, the entire transport path 50 or a part thereof (the left half or the right half) is formed between one divider and another divider that are adjacent to each other in the left-right direction.

[0058] Specifically, the right half of the first transport path 51 is formed between the first divider 111 and the second divider 112 in the left-right direction. The left half of the first transport path 51 is formed between the second divider 112 and the third divider 113 in the left-right direction. The right half of the second transport path 52 is formed between the third divider 113 and the fourth divider 114 in the left-right direction. The left half of the second transport path 52 is formed between the fourth divider 114 and the fifth divider 115 in the left-right direction. The third transport path 53 is formed between the fifth divider 115 and the sixth divider 116 in the left-right direction. The right half of the fourth transport path 54 is formed between the sixth divider 116 and the seventh divider 117 in the left-right direction. The left half of the fourth transport path 54 is formed between the seventh divider 117 and the eighth divider 118 in the left-right direction.

[0059] The first conveying path 51 is passed by planted stalks that have been divided by the first divider 111 and the second divider 112 and raised by the first raising device 31, and planted stalks that have been divided by the second divider 112 and the third divider 113 and raised by the second raising device 32.

[0060] The second conveying path 52 is passed by planted stalks that have been divided by the third divider 113 and the fourth divider 114 and raised by the third raising device 33, and planted stalks that have been divided by the fourth divider 114 and the fifth divider 115 and raised by the fourth raising device 34.

[0061] The planted stalks that have been divided by the fifth divider 115 and the sixth divider 116 and raised by the fifth raising device 35 pass through the third conveying path 53.

[0062] The fourth conveying path 54 is passed by the planted stalks divided by the sixth divider 116 and the seventh divider 117 and raised by the sixth raising device 36, and the planted stalks divided by the seventh divider 117 and the eighth divider 118 and raised by the seventh raising device 37.

[0063] 5 and 14, the lifting unit 29 has a drive shaft 41 that transmits driving force to the lifting device 30. The drive shaft 41 extends in the left-right direction from the top of the first lifting device 31 to the top of the seventh lifting device 37. A transmission case 42 is provided between the lifting device 30 and the drive shaft 41. The transmission case 42 houses a transmission shaft 42a that transmits the power of the drive shaft 41 to a drive sprocket 46 (described later) of the lifting device 30.

[0064] The lifting section 29 has a support frame 43 that supports the lifting devices 30. The support frame 43 extends in the left-right direction along the drive shaft 41 from the top of the first lifting device 31 to the top of the seventh lifting device 37. The support frame 43 supports the upper end of each lifting device 30.

[0065] As shown in Figures 5 and 13, the raising device 30 is equipped with a raising claw 44 that raises the planted stalks. The raising claw 44 is attached to a loop-shaped chain 45. The chain 45 is wound around a drive sprocket 46, a tension sprocket 47, and a roller 48. The chain 45 rotates as the drive sprocket 46 is driven. The raising claw 44 moves in accordance with the rotation of the chain 45, thereby raising the planted stalks.

[0066] As shown in Figure 13, the front of the chain 45, drive sprocket 46, tension sprocket 47, and roller 48 are covered by a lifting cover 49. A front surface 49a of the lifting cover 49 forms the front surface of the lifting device 30. As shown in Figure 15, the front surface 49a of the lifting cover 49 (the front surface of the lifting device 30) slopes upward toward the rear in a side view (a slope that slopes rearward as it extends upward). In other words, the lifting device 30 has a front surface 49a that slopes upward toward the rear in a side view.

[0067] The raising claw 44 can change its position between an upright position and a lying position relative to the chain 45. The raising claw 44 is in an upright position relative to the chain 45 on the conveying path 50. The raising claw 44 moves upward on the conveying path 50. As the raising claw 44 moves upward, the planted stalks are raised by the raising claw 44 and introduced into the conveying path 50.

[0068] 1 and 14, the reaping unit 8 includes a cutting blade device 25 and a stump transport unit 26. The cutting blade device 25 cuts the planted stumps raised by the raising unit 29. The stump transport unit 26 transports the planted stumps cut by the cutting blade device 25 rearward.

[0069] As shown in Figures 4 and 5, the reaping unit 8 is equipped with side covers 27. The side covers 27 are attached to the left and right parts of the reaping unit 8. The side surface (left face) of the left side cover 27 is located to the left of the first divider 111. The side surface (right face) of the right side cover 27 is located to the right of the eighth divider 118.

[0070] As shown in Figures 2 to 5, the reaping unit 8 has a plurality of dividing rods 60 that guide the planted stalks divided by the divider 11. The dividing rods 60 are formed from round rods with circular cross sections. The dividing rods 60 extend from the divider 11 toward the traveling body 2 below the dividing guide 80, which will be described later.

[0071] As shown in Figures 4 and 5, the dividing rod 60 is attached to the large dividers (first divider 111, third divider 113, fifth divider 115, sixth divider 116, and eighth divider 118) among the multiple dividers 11.

[0072] The dividing rod 60 includes a first dividing rod 61, a second dividing rod 62, a third dividing rod 63, a fourth dividing rod 64, and a fifth dividing rod 65. The first dividing rod 61 is attached to the first divider 111. The second dividing rod 62 is attached to the third divider 113. The third dividing rod 63 is attached to the fifth divider 115. The fourth dividing rod 64 is attached to the sixth divider 116. The fifth dividing rod 65 is attached to the eighth divider 118.

[0073] The first dividing rod 61 is attached to the left portion of the first divider 111. One end (front end) of the first dividing rod 61 is fixed to the left surface of the support plate 14 of the first divider 111. A middle portion of the first dividing rod 61 is fixed to the left surface of the support plate 14 of the first divider 111 by a fixing plate 66 (see FIG. 9). The first dividing rod 61 extends toward the upper left as it moves toward the rear.

[0074] The second dividing rods 62 are attached to the right and left parts of the third divider 113. One end (front end) and a middle part of the second dividing rods 62 are fixed to the support plate of the third divider 113. The right second dividing rod 62 extends upward and to the right as it moves rearward. The left second dividing rod 62 extends upward and to the left as it moves rearward.

[0075] The third dividing rods 63 are attached to the right and left parts of the fifth divider 115. One end (front end) and a middle part of the third dividing rods 63 are fixed to the support plate of the fifth divider 115. The right third dividing rod 63 extends upward and to the right as it moves rearward. The left third dividing rod 63 extends upward and to the left as it moves rearward.

[0076] The fourth dividing rod 64 is attached to the left part of the sixth divider 116. One end (front end) and a middle part of the fourth dividing rod 64 are fixed to the support plate of the sixth divider 116. The fourth dividing rod 64 extends toward the upper left as it moves toward the rear.

[0077] The fifth dividing rod 65 is attached to the right part of the eighth divider 118. One end (front end) and a middle part of the fifth dividing rod 65 are fixed to the support plate of the eighth divider 118. The fifth dividing rod 65 extends upward and to the right as it moves rearward.

[0078] As shown in Figures 1 to 5, the reaping unit 8 has a grass dividing guide 80 that guides the planted stalks divided by the divider 11. The grass dividing guide 80 is formed from a round bar with a circular cross section. The grass dividing guide 80 guides the planted stalks above the grass dividing rod 60.

[0079] The cutting unit 8 is equipped with a plurality of grass guides 80. As shown in Figures 4 and 5, the plurality of grass guides 80 include a first grass guide 81, a second grass guide 82, a third grass guide 83, a fourth grass guide 84, and a fifth grass guide 85.

[0080] The first grass dividing guide 81 is attached to the first divider 111, which is located on the farthest side (right side) of the multiple dividers 11 lined up in the left-right direction. Therefore, the first grass dividing guide 81 is located in front of the cabin 5. The fifth grass dividing guide 85 is attached to the eighth divider 118, which is located on the farthest side (left side) of the multiple dividers 11 lined up in the left-right direction.

[0081] The second grass guide 82, the third grass guide 83, and the fourth grass guide 84 are arranged left-right between the first grass guide 81 and the fifth grass guide 85. The second grass guide 82 is attached to the third divider 113. The third grass guide 83 is attached to the fifth divider 115. The fourth grass guide 84 is attached to the sixth divider 116.

[0082] The configuration of the first grass dividing guide 81 will be described in detail below. As shown in Figures 6 to 12, the first grass dividing guide 81 has an attachment portion 80a and a guide portion 80b. The attachment portion 80a is provided on one end 81a of the first grass dividing guide 81 and is attached to the first divider 111. The attachment portion 80a is attached to the front of the first divider 111. More specifically, the attachment portion 80a is attached to the front end of the first divider 111. The "front of the divider" refers to the portion that is forward of the center of the divider in the fore-and-aft direction. The "front end of the divider" refers to the portion that is forward of the divider main body 13.

[0083] The mounting portion 80a is attached to the support plate 14 of the first divider 111. As shown in Figures 11 and 12, the mounting portion 80a is attached to the support plate 14 forward of the divider body 13 of the first divider 111. In other words, the mounting portion 80a is attached to a portion of the support plate 14 that is forward of the divider body 13. However, the mounting portion 80a does not protrude forward beyond the front end of the support plate 14.

[0084] As shown in Figures 6, 8, and 9, the mounting portion 80a is formed in a V-shape. More specifically, the mounting portion 80a is formed in a V-shape when viewed from above. The mounting portion 80a is positioned so that the corner of the V is located at the front end. The mounting portion 80a is engaged with a first through-hole 14b formed in the support plate 14. The mounting portion 80a is engaged with the first through-hole 14b from the side (left) of the support plate 14. As a result, the mounting portion 80a is attached to the front portion (front end portion) of the first divider 111 from the side (left) of the first divider 111.

[0085] The mounting portion 80a is merely engaged (hooked) in the first through-hole 14b of the support plate 14, but is not fixed to the support plate 14. The inner diameter of the first through-hole 14b is larger than the outer diameter of the mounting portion 80a. This allows the mounting portion 80a to move relative to the support plate 14. This prevents stress from concentrating on the mounting portion 80a when an external force is applied to the first grass guide 81.

[0086] 11 , one end 81a of the first grass dividing guide 81 is located below the top surface of the first divider 111. One end 81a of the first grass dividing guide 81 is located below the divider body 13 of the first divider 111. One end 81a of the first grass dividing guide 81 is located to the side (right side) of the support plate 14 of the first divider 111.

[0087] The guide portion 80b of the first grass dividing guide 81 extends from the mounting portion 80a, passing to the side (left) of the first divider 111, and above the first divider 111. As shown in Figures 10 and 11, in a side view, the front portion of the guide portion 80b overlaps with the first divider 111. Therefore, the front portion of the guide portion 80b passes above the side of the first divider 111. In addition, the rear portion of the guide portion 80b is located above the first divider 111. Therefore, the guide portion 80b extends above the first divider 111.

[0088] As shown in Figure 13, the guide portion 80b extends diagonally upward from the attachment portion 80a toward the conveying path 50 in a front view. Specifically, the guide portion 80b of the first grass dividing guide 81 extends diagonally upward to the left from the attachment portion 80a toward the first conveying path 51 in a front view. Also, as shown in Figure 16, the guide portion 80b of the first grass dividing guide 81 extends diagonally backward in a top view, transitioning to the left as it approaches the rear.

[0089] The first grass guide 81 having the above-described configuration can function to prevent the planted culms from falling (leaning) from the side of the divider 11 onto the top of the divider 11. The function of this first grass guide 81 will be explained in detail later.

[0090] 13, the other end 81b of the first grass dividing guide 81 that divides the planted stumps toward the first raising device 31 is arranged in a position that overlaps with the first conveying path 51 in a front view but does not overlap with the movement trajectory 44L of the tip of the raising claw 44 of the second raising device 32. In other words, the other end 81b of the first grass dividing guide 81 that divides the first planted stump of the multiple planted stumps is arranged in a position that overlaps with the first conveying path 51 that conveys the first planted stump but does not overlap with the movement trajectory 44L of the tip of the raising claw 44 of the second raising device 32 that raises the second planted stump adjacent to the first row in a front view.

[0091] 15, the other end (rear end) 81b of the first grass dividing guide 81 is located rearward of the rear end 111c of the first divider 111 in the front-to-rear direction and farther from the front surface 49a of the lifting device 30 than the rear end 111c of the first divider 111. In addition, the other end 81b of the first grass dividing guide 81 is located above the upper surface 111a of the first divider 111 in the up-down direction. In addition, the other end 81b of the first grass dividing guide 81 is located forward of an imaginary line L1 connecting the rear end 61a of the first grass dividing rod 61 and the rear end 111c of the first divider 111 in the front-to-rear direction.

[0092] As shown in Figure 15, the height of the other end 81b of the first grass guide 81 is lower than the height of the horizontal portions 82 to 85 of the other grass guides (second to fifth grass guides). Also, as shown in Figure 16, the other end (rear end) 81b of the first grass guide 81 is located rearward and to the left of the rear end 61a of the first grass rod 61 in the front-to-rear direction.

[0093] As shown in Figures 6 to 12, the guide portion 80b has a first portion 80b1, a second portion 80b2, and a bent portion 80b3. The first portion 80b1 is a portion located on the one end 81a side of the first grass dividing guide 81. The second portion 80b2 is a portion located on the other end 81b side of the first grass dividing guide 81. The bent portion 80b3 is provided between the first portion 80b1 and the second portion 80b2 (at the boundary). The second portion 80b2 is located behind the first portion 80b1. The bent portion 80b3 is formed midway in the front-to-rear direction of the guide portion 80b.

[0094] 6, the first portion 80b1 extends along the side surface of the first divider 111. More specifically, the first portion 80b1 extends along the side surface (left side surface 13a1) of the front portion 13a of the divider body 13 of the first divider 111 in a front view.

[0095] As shown in FIG. 6 , in a front view, the inclination angle α2 of the second portion 80b2 relative to the vertical direction is smaller than the inclination angle α1 of the first portion 80b1 relative to the vertical direction (α2<α1). Also, in a front view, the inclination angles α1 of the first portion 80b1 relative to the vertical direction and the inclination angle α2 of the second portion 80b2 relative to the vertical direction are smaller than the inclination angle α3 of the first dividing rod 61 relative to the vertical direction (α1, α2<α3). Also, in a front view, the inclination angle α1 of the first portion 80b1 relative to the vertical direction is larger than the inclination angle α4 of the side surface (left surface) of the front portion 13a of the divider main body 13 relative to the vertical direction (α1>α4). Also, in a front view, the inclination angle α2 of the second portion 80b2 relative to the vertical direction is smaller than the inclination angle α4 of the side surface (left surface) of the front portion 13a of the divider main body 13 relative to the vertical direction (α2<α4).

[0096] 8, in a top view, the inclination angle β2 of the second portion 80b2 with respect to the front-to-rear direction is smaller than the inclination angle β1 of the first portion 80b1 with respect to the front-to-rear direction (β2<β1). Also, in a top view, the inclination angle β1 of the first portion 80b1 with respect to the front-to-rear direction and the inclination angle β2 of the second portion 80b2 with respect to the front-to-rear direction are smaller than the inclination angle β3 of the first branch rod 61 with respect to the front-to-rear direction (β1, β2<β3).

[0097] 10 , in a side view, the inclination angle γ2 of the second portion 80b2 relative to the horizontal is greater than the inclination angle γ1 of the first portion 80b1 relative to the horizontal (γ2 > γ1). Also, in a side view, the inclination angles γ1 of the first portion 80b1 relative to the horizontal and the inclination angle γ2 of the second portion 80b2 relative to the horizontal are greater than the inclination angle γ3 of the first dividing rod 61 relative to the horizontal (γ1, γ2 > γ3). Also, in a side view, the inclination angles γ1 of the first portion 80b1 relative to the horizontal and the inclination angle γ2 of the second portion 80b2 relative to the horizontal are greater than the inclination angle γ4 of the upper surface of the divider body 13 (the upper surface 11a of the divider 11) relative to the horizontal (γ1, γ2 > γ4).

[0098] As shown in Figures 6 and 16, the first grass dividing guide 81 is positioned so that its left-right position does not exceed the end 111b on one side (right side) of the first divider 111. Also, as shown in Figures 4 and 16, the first grass dividing guide 81 is positioned so that its left-right position does not exceed the end 27a on one side (right side) of the right side cover 27. In other words, the end 81a of the first grass dividing guide 81 is located to the left of the end 111b on one side (right side) of the first divider 111 and the right end 27a of the right side cover 27. In Figure 16, the left-right position of the right end 27a of the right side cover 27 is indicated by an imaginary line La. The end 81a of the first grass dividing guide 81 is located to the left of the imaginary line La in the left-right direction.

[0099] The first grass guide 81 is fixed only to the divider (first divider 111). In other words, the first grass guide 81 is not fixed to any part other than the divider (first divider 111). The fixing structure of the first grass guide 81 will be described below.

[0100] As shown in Figures 7, 9, 12, etc., the first grass dividing guide 81 is fixed to the first divider 111 by a fixing device 90. The fixing device 90 has a first member 91 and a second member 92. The first member 91 is formed in a flat plate shape. The first member 91 is fixed to the guide portion 80b (first portion 80b1) of the first grass dividing guide 81. The first member 91 extends from the guide portion 80b (first portion 80b1) past the side (left side) of the divider main body 13 toward the lower left.

[0101] The second member 92 is formed in a U-shape. One end of the second member 92 (one end of the U-shape) is attached to the first member 91 by a first mounting fixture 93 (bolt and nut). The other end of the second member 92 (the other end of the U-shape) is attached to the support plate 14 below the divider body 13 by a second mounting fixture 94 (bolt and nut). A through hole 14e is formed in the support plate 14 through which the bolt of the second mounting fixture 94 is inserted (see FIG. 12 ). The second member 92 is rotatable relative to the first member 91, with the first mounting fixture 93 serving as a fulcrum. This allows the angle of the second member 92 relative to the first member 91 to be adjusted. The second member 92 is disposed below the divider body 13.

[0102] As shown in Figure 6, the fixing device 90 is arranged to pass between the first dividing guide 81 and the first dividing rod 61 when viewed from the front. As shown in Figure 8, the fixing device 90 is also arranged to pass between the first dividing guide 81 and the first dividing rod 61 when viewed from above. The space SP1 between the first dividing guide 81 and the first dividing rod 61 is a space through which the planted stalks do not pass. Therefore, by placing the fixing device 90 in a position that passes between the first dividing guide 81 and the first dividing rod 61, it is possible to prevent the fixing device 90 from obstructing the transport of the planted stalks.

[0103] 9 and other figures, the fixing device 90 is attached to the support plate 14 below the divider body 13 by the second attachment device 94, so that the upper part of the second attachment device 94 is covered by the divider body 13. Therefore, it is possible to prevent the second attachment device 94 from interfering with the transportation of the planted stalks.

[0104] Next, we will explain the configuration of the second grass guide 82 to the fifth grass guide 85. As will be explained below, in this embodiment, the configuration of the second grass guide 82 to the fifth grass guide 85 is significantly different from the configuration of the first grass guide 81.

[0105] As shown in Figures 5 and 13, the second grass dividing guide 82 is positioned between the second lifting device 32 and the third lifting device 33 in a front view. As shown in Figures 13 and 15, the second grass dividing guide 82 has a vertical portion 82a and a horizontal portion 82b. The vertical portion 82a extends approximately vertically. The lower portion of the vertical portion 82a is inserted from above into a through-hole 112a formed in the rear portion of the second divider 112. The horizontal portion 82b extends rearward and upward from the upper portion of the vertical portion 82a. The rear portion of the horizontal portion 82b is inserted from the front between the second lifting device 32 and the third lifting device 33 and is fixed to a bracket (not shown) located behind the lifting cover 49. The second grass dividing guide 82 is not fixed to the second divider 112, but is fixed only to the bracket.

[0106] The third grass guide 83 is positioned between the fourth lifting device 34 and the fifth lifting device 35 in a front view. The shape of the third grass guide 83 is the same as that of the second grass guide 82. The lower part of the third grass guide 83 is inserted from above into a through hole formed in the rear part of the fifth divider 115. The upper part of the third grass guide 83 is inserted from the front between the fourth lifting device 34 and the fifth lifting device 35 and is fixed to a bracket (not shown) located behind the lifting cover 49. The third grass guide 83 is not fixed to the fifth divider 115, but is fixed only to the bracket.

[0107] The fourth grass guide 84 is positioned between the fifth lifting device 35 and the sixth lifting device 36 when viewed from the front. The shape of the fourth grass guide 84 is the same as that of the second grass guide 82. The lower part of the fourth grass guide 84 is inserted from above into a through hole formed in the rear part of the sixth divider 116. The upper part of the fourth grass guide 84 is inserted from the front between the fifth lifting device 35 and the sixth lifting device 36 and is fixed to a bracket (not shown) positioned behind the lifting cover 49. The fourth grass guide 84 is not fixed to the sixth divider 116, but is fixed only to the bracket.

[0108] The fifth grass guide 85 is positioned so that it overlaps the seventh lifting device 37 in a front view. The fifth grass guide 85 has the same shape as the second to fourth grass guides 82 to 84 in the vertical portion 85a, but a different shape in the horizontal portion 85b. As shown in FIG. 15 and other figures, the horizontal portion 85b of the fifth grass guide 85 extends diagonally upward and rearward, reaching higher than the horizontal portions 82b to 84b of the second to fourth grass guides 82 to 84. The lower portion of the fifth grass guide 85 is inserted from above into a through-hole formed in the rear portion of the eighth divider 118. The upper portion of the fifth grass guide 85 is inserted from the front between the sixth lifting device 36 and the seventh lifting device 37, at a position higher than the upper ends of the second to fourth grass guides, and is fixed to the support frame 43. The fifth divider guide 85 is not fixed to the eighth divider 118, but is fixed only to the support frame 43.

[0109] As can be seen from the above description and drawings, the multiple grass dividing guides 80 can be broadly divided into two types. The first type is a grass dividing guide that is engaged with the front part of the divider 11, and corresponds to the first grass dividing guide 81. The second type is a grass dividing guide that is inserted into the rear part of the divider 11, and corresponds to the second grass dividing guide 82, third grass dividing guide 83, fourth grass dividing guide 84, and fifth grass dividing guide 85. In other words, in this embodiment, the cutting unit 8 is equipped with two different types of grass dividing guides (first type and second type).

[0110] 15, in a side view, the first grass guide 81 intersects with the other grass guides (second grass guide 82, third grass guide 83, fourth grass guide 84, fifth grass guide 85) attached to the other dividers (third divider 113, fifth divider 115, sixth divider 116, eighth divider 118) different from the first divider 111. In detail, in a side view, the guide portion 80b of the first grass guide 81 intersects with the vertical portions 82a, 83a, 84a, 85a of the other grass guides (second grass guide 82, third grass guide 83, fourth grass guide 84, fifth grass guide 85) attached to the other dividers (third divider 113, fifth divider 115, sixth divider 116, eighth divider 118) different from the first divider 111.

[0111] The inclination angle θ1 relative to the horizontal direction of the guide portion 80b (second portion 80b2) of the first grass dividing guide 81 is smaller than the inclination angle θ2 relative to the horizontal direction of the vertical portions 82a, 83a, 84a, 85a of other grass dividing guides (second grass dividing guide 82, third grass dividing guide 83, fourth grass dividing guide 84, fifth grass dividing guide 85) attached to other dividers other than the first divider 111 (third divider 113, fifth divider 115, sixth divider 116, eighth divider 118) (θ1 < θ2).

[0112] As shown in Figure 11, one end 81a of the first dividing guide 81 is located forward and below the first dividing rod 61. The mounting portion 81a of the first dividing guide 81 is also located forward and below the first dividing rod 61. In addition, the other end 81b of the first dividing guide 81 is located rearward and above the first dividing rod 61. As shown in Figure 6, the first dividing guide 81 is positioned so that it passes between the first divider 111 (divider body 13) and the first dividing rod 61 when viewed from the front.

[0113] The function (action) of the first grass dividing guide 81 will be explained below with reference to Figures 17 to 19. Figure 17 is an explanatory diagram of the combine harvester 1 as seen from the front. Figure 18 is an explanatory diagram of the combine harvester 1 as seen from the side (left). Figure 19 is an explanatory diagram of the combine harvester 1 as seen from above.

[0114] First, before explaining the function (action) of the first grass dividing guide 81, we will explain the problems that combine harvesters that do not have the first grass dividing guide 81 configured as described above have.

[0115] When the reaping unit 8 of the combine harvester 1 harvests multiple rows of planted culms in a field, it often moves counterclockwise around the field to harvest the planted culms. In this case, of the multiple dividers 11 provided in the reaping unit 8, it is necessary to guide the row that is furthest to the right (hereinafter simply referred to as the "rightmost row") as viewed from the direction of travel of the combine harvester 1 to the left of the first divider 111 (between the first divider 111 and the second divider 112). Therefore, an alignment operation is required to position the first divider 111 near the right side of the rightmost row.

[0116] This alignment work is performed by the operator OP seated in the driver's seat 6 in the cabin 5 while looking at the first divider 111 from above. However, if the planting stumps are tilted, it is difficult for the operator OP to grasp the position of the first divider 111. In particular, if the planting stumps of the rightmost row are tilted to the right, the planting stumps will be lying (leaning) above the first divider 111, making it difficult for the operator OP to see the first divider 111 from above. This makes it difficult for the operator OP to confirm the position of the first divider 111 relative to the planting stumps, making it difficult to accurately perform the above-mentioned alignment work. In particular, if the position of the front part (particularly the front end) of the first divider 111 cannot be confirmed, it is extremely difficult to accurately perform the alignment work.

[0117] The above-mentioned problems can be solved by a combine harvester 1 in which the cutting unit 8 is equipped with a first grass cutting guide 81. The left diagrams of Figures 17 and 18 and the top diagram of Figure 19 show the state in which the first grass cutting guide 81 has begun to contact the planted culm UT of the rightmost row. The right diagrams of Figures 17 and 18 and the bottom diagram of Figure 19 show the state in which the combine harvester 1 has moved forward a little after the first grass cutting guide 81 has begun to contact the planted culm UT of the rightmost row.

[0118] In this example, when the first grass dividing guide 81 begins to contact the planted grain culm UT in the rightmost row, the planted grain culm UT tilts to the right and is in a state of lying (leaning) above the first divider 111 (see the left diagrams of Figures 17 and 18 and the top diagram of Figure 19). In this state, the front end of the first grass dividing guide 81 is in contact with the right side of the base of the planted grain culm UT that has fallen above the first divider 111. When the combine harvester 1 moves forward from this state, the planted grain culm UT that has fallen above the first divider 111 is guided by the guide portion 81b of the first grass dividing guide 81 and raised toward the left (see the right diagrams of Figures 17 and 18 and the bottom diagram of Figure 19). As a result, the planted grain culm UT that has fallen above the first divider 111 is removed from above the first divider 111.

[0119] In this way, the planted culms UT, which were in a position blocking the line of sight S1 when the operator OP was looking at the first divider 111, are guided by the first dividing guide 81 and raised to the left, so that they no longer block the line of sight S1. This allows the operator OP inside the cabin 5 to reliably see the first divider 111 from above. As a result, it is possible to run the traveling body 2 so that the divider 11 reliably passes near the side of the planted culms that have been planted in rows, and it is possible to prevent the divider 11 from knocking over or piercing the planted culms.

[0120] Furthermore, because the mounting portion 80a of the first dividing guide 81 is attached to the front or front end of the first divider 111, the guide portion 80b can guide and raise the planted stumps that are located to the side of the front or front end of the first divider 111. This prevents the planted stumps UT from falling over onto the front or front end of the first divider 111. This prevents the planted stumps UT from blocking the operator OP's line of sight S1 when attempting to check the position of the front or front end of the first divider 111. This allows the operator OP to easily check the position of the front or front end of the first divider 111, making it possible to perform the above-mentioned alignment work more accurately.

[0121] The functions (actions) of the first grass dividing guide 81 described above are the most representative functions (actions) of the first grass dividing guide 81. Other functions (actions) that are exerted based on the specific shape and arrangement of the first grass dividing guide 81 are explained in the itemized sections described later (sections labeled (item 1), (item 2), etc.).

[0122] The reaping unit 8 is equipped with an adjustment mechanism capable of adjusting the position of the divider 11. In the present embodiment, the reaping unit 8 is equipped with an adjustment mechanism capable of adjusting the position of the first divider 111 and an adjustment mechanism capable of adjusting the position of the eighth divider 118. Because the adjustment mechanism for the first divider 111 and the adjustment mechanism for the eighth divider 118 have the same configuration, the adjustment mechanism for the first divider 111 will be described below.

[0123] The adjustment mechanism includes a first adjustment mechanism 95 that adjusts the vertical position (angle) of the first divider 111, and a second adjustment mechanism 96 that adjusts the horizontal position (angle) of the first divider 111. Figure 20 is a side view showing the function (operation) of the first adjustment mechanism 95. Figure 21 is a plan view showing the function (operation) of the second adjustment mechanism 96.

[0124] The first adjustment mechanism 95 includes a through hole 17a formed in the mounting plate 17, a through hole 14d formed in the support plate 14, a bolt BL1, and a nut NT1 (see FIG. 12 ). As described above, the rear through hole 17a of the two through holes 17a is an elongated arc-shaped hole extending from a lower rearward position to an upper frontward position. Therefore, by changing the position of the bolt BL1 relative to this elongated rear through hole 17a, the vertical position (angle) of the first divider 111 can be adjusted. Specifically, the first divider 111 can be swung up and down around the bolt BL1 inserted through the front through hole 17a (see the solid and phantom lines in FIG. 20 ).

[0125] The second adjustment mechanism 96 has through holes (first hole 19a, second hole 19b, third hole 19c) formed in the connecting member 19, through holes (fourth hole 15a, fifth hole 15b, sixth hole 15c) formed in the base plate 15, a bolt BL2, and screw holes (first screw hole, second screw hole, third screw hole) formed in the grass dividing frame 12 (see Figure 12). As mentioned above, the third hole 19c is located to the right rear of the second hole 19b. Therefore, the left-right position (angle) of the first divider 111 can be adjusted by removing the bolt BL2 that was threaded into the second screw hole of the grass dividing frame 12 through the second hole 19b and changing it so that it is threaded into the third screw hole through the third hole 19c. Specifically, the first divider 111 can be swung left and right around the bolt BL2 inserted through the first hole 19a (see the upper and lower diagrams in FIG. 21).

[0126] The first grass dividing guide 81 moves together with the first divider 111 as the position of the first divider 111 is adjusted by the adjustment mechanism (first adjustment mechanism 95, second adjustment mechanism 96). This makes it possible to maintain a constant positional relationship between the first divider 111 and the first grass dividing guide 81, even when the position of the first divider 111 is adjusted. Therefore, when the position of the first divider 111 is adjusted, good grass dividing and transport performance can be maintained without adjusting the position of the first grass dividing guide 81.

[0127] Furthermore, the first dividing rod 61 also moves together with the first divider 111 as the position of the first divider 111 is adjusted by the adjustment mechanisms (first adjustment mechanism 95, second adjustment mechanism 96). This makes it possible to maintain a constant positional relationship between the first divider 111, the first dividing guide 81, and the first dividing rod 61 even when the position of the first divider 111 is adjusted.

[0128] Although a preferred embodiment of the combine harvester 1 according to the present invention has been described above, the combine harvester 1 may adopt other embodiments as described below.

[0129] As described above, the multiple grass dividing guides 80 are broadly divided into a first type (corresponding to the first grass dividing guide 81) that is engaged with the front part of the divider 11, and a second type (corresponding to the second grass dividing guide 82, third grass dividing guide 83, fourth grass dividing guide 84, and fifth grass dividing guide 85) that is inserted into the rear part of the divider 11.

[0130] In the above embodiment, the rightmost grass guide (first grass guide 81) is the first type of grass guide, but the leftmost grass guide (fifth grass guide 85) may also be the first type of grass guide. In this case, the configuration of the fifth grass guide 85 is symmetrical (symmetrical across the center line of the width of the traveling body 2) to the configuration of the first grass guide 81 shown in Figures 6 to 12.

[0131] In this case, only the fifth grass guide 85 may be type 1, or both the first grass guide 81 and the fifth grass guide 85 may be type 1. In the former case, only the leftmost grass guide will be type 1. Therefore, this is suitable, for example, for performing mowing work in a clockwise direction in a field. In the latter case, the rightmost and leftmost grass guides will be type 1, so mowing work can be performed in both a clockwise and counterclockwise direction. Therefore, this is suitable, for example, for performing a mowing work known as "middle splitting," in which the center of the field is first mowed and then the right and left sides are mowed separately.

[0132] In addition, in the above embodiment, the second grass guide 82, the third grass guide 83, the fourth grass guide 84, and the fifth grass guide 85 are all type 2 grass guides, but some or all of these grass guides may also be type 1 grass guides. In other words, some or all of the first grass guide 81 to the fifth grass guide 85 may be type 1 grass guides.

[0133] Furthermore, in the above embodiment, the first type grass dividing guide (first grass dividing guide 81) is attached to only one side (the left side) of the divider (first divider 111) in the left-right direction, but the first type grass dividing guide may also be attached to both the left and right sides of the divider. In this case, the first type grass dividing guide may be attached to the left and right sides of the first divider 111, or the first type grass dividing guide may be attached to the left and right sides of the eighth divider 118. Furthermore, the first type grass dividing guide may be attached to the left and right sides of some or all of the second divider 112 to the seventh divider 117.

[0134] Although the mounting portion 80 a is V-shaped in the above embodiment, the mounting portion 80 a may have any other shape as long as it can be engaged with the first through-hole 14 b. For example, the mounting portion 80 a may be L-shaped, C-shaped, J-shaped, etc.

[0135] An embodiment of the present invention provides a combine harvester 1 described in the following items.

[0136] (Item 1) A combine harvester 1 comprising a traveling body 2 and a reaping unit 8 provided at the front of the traveling body 2 to reaper planted culms, the reaping unit 8 having a divider 11 that divides the base-side portion of the planted culms and a grass-dividing guide 80 that guides the planted culms divided by the divider 11, the grass-dividing guide 80 having an attachment portion 80a provided at one end 81a of the grass-dividing guide 80 and attached to the divider 11, and a guide portion 80b that extends from the attachment portion 80a, passing beside the divider 11, to a position above the divider 11. (See Figures 1 to 11, etc.)

[0137] According to the combine harvester 1 of this item 1, the grass dividing guide 80 can prevent the planted culms from falling over (leaning) above the divider 11. Therefore, during harvesting work, the operator can easily check the position of the divider 11 relative to the planted culms. This allows the divider 11 to be accurately positioned relative to the planted culms that have been planted in rows.

[0138] (Item 2) The combine harvester 1 according to Item 1, wherein the mounting portion 80a is attached to a front portion of the divider 11, and the guide portion 80b extends from the front portion of the divider 11, passing along a side of the divider 11, and above the divider 11 (see Figures 6, 10, 11, etc.).

[0139] According to the combine harvester 1 of this item 2, since the mounting portion 80a is attached to the front of the divider 11, it is possible to prevent the planted culms from falling over in front of the divider 11. Therefore, during harvesting work, the operator can easily check the position of the front of the divider 11 relative to the planted culms. This allows for more accurate alignment of the divider 11 with the planted culms that have been planted in rows.

[0140] (Item 3) The combine harvester 1 according to Item 1, wherein the mounting portion 80a is attached to a front end portion of the divider 11, and the guide portion 80b extends from the front end portion of the divider 11, passing along the side of the divider 11, and above the divider 11 (see Figures 6, 10, 11, etc.).

[0141] According to the combine harvester 1 of this third aspect, the attachment portion 80a is attached to the front end of the divider 11, which prevents the planted stumps from falling over onto the front end of the divider 11. Therefore, during harvesting, the operator can easily check the position of the front end of the divider 11 relative to the planted stumps. This allows for more accurate alignment of the divider 11 relative to the planted stumps that have been planted in rows.

[0142] (Item 4) The combine harvester 1 according to any one of Items 1 to 3, wherein the attachment portion 80a is attached to a front portion of the divider 11 from a side of the divider 11 (see Figures 6, 8 to 11, etc.).

[0143] According to the combine harvester 1 of this item 4, the grass dividing guide 80 can be brought into contact with the planted culms from a lower position than when the attachment portion 80a is attached from above the divider 11. This allows tilted planted culms to be raised from near the base of the plant. This effectively prevents the planted culms from falling over above the divider 11, and improves visibility of the front of the divider 11.

[0144] (Item 5) The combine harvester 1 according to any one of Items 1 to 4, wherein a through-hole (first through-hole 14b) is formed in the front portion of the divider 11, and the attachment portion 80a is formed in a V-shape and is engaged with the through-hole (first through-hole 14b) (see Figures 6, 8 to 11, etc.).

[0145] According to the combine harvester 1 relating to this item 5, since the attachment portion 80a is not completely fixed to the divider 11, stress concentration on the attachment portion 80a can be prevented when an external force is applied to the grass dividing guide 80. Furthermore, compared to when the grass dividing guide 80 is attached to the divider 11 using a separate member such as a bolt, the resistance that the grass dividing guide receives from the planted culms can be reduced and high grass dividing performance can be achieved. Furthermore, the grass dividing guide 80 can be easily attached and detached to the divider 11.

[0146] (Item 6) The combine harvester 1 according to any one of Items 1 to 5, wherein one end 81a of the grass dividing guide 80 is located below the upper surface 11a of the divider 11. (See Figures 10, 11, etc.)

[0147] According to the combine 1 relating to item 6, it is possible to prevent the planted culms from getting caught on one end 81a of the grass dividing guide 80, thereby reducing the resistance that the grass dividing guide 80 receives from the planted culms and enabling high grass dividing performance to be exhibited.

[0148] (Item 7) The combine harvester 1 according to any one of items 1 to 6 is provided with a raising device 30 including a raising claw 44 that raises the planted stumps divided by the divider 11, and the raising devices 30 are arranged in a row in the left-right direction, and a transport path (first transport path 51) through which the raised planted stumps pass is formed between one raising device (first raising device 31) and another raising device (second raising device 32) adjacent to each other in the left-right direction, and the other end 81b of the grass dividing guide (first grass dividing guide 81) that divides the planted stumps toward the one raising device is positioned in a position that overlaps with the transport path (first transport path 51) in a front view but does not overlap with the movement trajectory 44L of the tip of the raising claw 44 of the other raising device. (See Figures 5, 13, etc.)

[0149] According to the combine harvester 1 relating to this item 7, the planted stalks divided by the dividing guide (first dividing guide 81) can be smoothly guided to the transport path 50. In addition, the guided planted stalks can be prevented from reaching the movement trajectory 44L of the tip of the raising claw 44 of another raising device (second raising device 32). This makes it possible to achieve both visibility of the divider 11 and transport performance of the planted stalks.

[0150] (Item 8) The combine harvester 1 according to any one of items 1 to 6 is provided with a raising device 30 including a raising claw 44 that raises the planted stalks divided by the divider 11, the raising device 30 has a front surface 49a that rises rearward in a side view, and the other end 81b of the grass dividing guide 80 is located rearward of the rear end 111c of the divider 11 in the front-to-rear direction and at a position farther from the front surface 49a than the rear end 111c of the divider 11. (See Figures 5, 15, etc.)

[0151] The combine harvester 1 according to item 8 can prevent the adverse effects caused by the other end 81b of the grass dividing guide 80 being too far away from the front face 49a of the raising device 30 (the planted culms becoming more likely to get caught between the other end 81b of the grass dividing guide 80 and the front face 49a, reducing the transport performance of the planted culms). It can also prevent the adverse effects caused by the length from one end 81a to the other end 81b of the grass dividing guide 80 being longer (the grass dividing guide 80 becoming more likely to vibrate, reducing the strength of the grass dividing guide 80).

[0152] (Item 9) The combine harvester 1 according to any one of items 1 to 6, which is provided with a raising device 30 including a raising claw 44 that raises the planted stumps divided by the divider 11, and the raising devices 30 are arranged in a row in the left-right direction, and a transport path 50 through which the raised planted stumps pass is formed between one raising device (first raising device 31) and another raising device (second raising device 32) adjacent to each other in the left-right direction, and the guide portion 80b of the grass dividing guide (first grass dividing guide 81) that divides the planted stumps toward one raising device extends obliquely upward from the mounting portion 80a and toward the transport path 50 (first transport path 51) in a front view. (See Figures 5, 13, etc.)

[0153] The combine harvester 1 according to this item 9 can prevent the planted culms from falling over from the side of the dividing guide (first dividing guide 81) that divides the planted culms toward one raising device (first raising device 31), and can smoothly guide the planted culms raised by the dividing guide (first dividing guide 81) into the transport path (first transport path 51). Therefore, it is possible to achieve both visibility of the divider 11 and transport performance of the planted culms.

[0154] (Item 10) The guide portion 80b has a first portion 80b1 located on one end 81a side of the grass dividing guide 80, a second portion 80b2 located on the other end 81b side of the grass dividing guide 80, and a bent portion 80b3 provided between the first portion 80b1 and the second portion 80b2, and in a front view, the inclination angle α2 of the second portion 80b2 with respect to the front-to-back direction is smaller than the inclination angle α1 of the first portion 80b1 with respect to the up-down direction. (See Figure 6)

[0155] According to the combine harvester 1 of this item 10, the first portion 80b1, which has a large inclination angle relative to the vertical direction, can move the planted grain stalks upward and away from the divider 11 over a short distance, thereby effectively preventing the planted grain stalks from falling over above the divider 11. Furthermore, the second portion 80b2, which has a small inclination angle relative to the vertical direction, can reliably guide the planted grain stalks to the conveying path. In other words, by making the inclination angles relative to the vertical direction of the first portion 80b1 and the second portion 80b2 different, it is possible to reliably guide the planted grain stalks to the conveying path while effectively preventing the planted grain stalks from falling over above the divider 11.

[0156] (Item 11) The guide portion 80b has a first portion 80b1 located on one end 81a side of the grass dividing guide 80, a second portion 80b2 located on the other end 81b side of the grass dividing guide 80, and a bent portion 80b3 provided between the first portion 80b1 and the second portion 80b2, and in a top view, the inclination angle β2 of the second portion 80b2 relative to the front-to-rear direction is smaller than the inclination angle β1 of the first portion 80b1 relative to the front-to-rear direction. (See Figure 8)

[0157] According to the combine harvester 1 of this item 11, the first portion 80b1, which has a large inclination angle relative to the front-to-rear direction, can move the planted stumps laterally (to the left or right) away from the divider 11 over a short distance, thereby effectively preventing the planted stumps from falling over above the divider 11. Furthermore, the second portion 80b2, which has a small inclination angle relative to the front-to-rear direction, can reliably guide the planted stumps to the conveying path. In other words, by making the inclination angles relative to the front-to-rear direction of the first portion 80b1 and the second portion 80b2 different, it is possible to reliably guide the planted stumps to the conveying path while effectively preventing the planted stumps from falling over above the divider 11.

[0158] (Item 12) The combine harvester 1 according to Item 10 or 11, wherein the first portion 80b1 extends along the side surface 13a1 of the divider 11 (see FIG. 6, etc.).

[0159] According to the combine 1 relating to item 12, the grass dividing function of the divider 11 is not hindered by the first part 80b1, so the grass dividing function of the divider 11 can be maintained while the guiding function of the guide part 80b of the grass dividing guide 80 can be exerted.

[0160] (Item 13) The combine harvester 1 according to any one of Items 1 to 12, wherein the grass dividing guide 80 is fixed only to the divider 11. (See FIG. 12, etc.)

[0161] According to the combine harvester 1 relating to this item 13, the transport of planted stalks can be carried out more smoothly than when the grass dividing guide 80 is fixed to a location other than the divider 11. For example, if the grass dividing guide 80 is fixed to the raising cover 49 of the raising device 30 by a fixing device, the fixing device being interposed between the raising cover 49 and the grass dividing guide 80 will hinder the transport of the planted stalks, but by fixing the grass dividing guide 80 only to the divider 11, such a problem will not occur.

[0162] (Item 14) The combine harvester 1 according to any one of items 1 to 13, further comprising a fixing device 90 that fixes the grass dividing guide 80 to the divider 11, and a grass dividing rod 60 that is attached to the divider 11 and extends below the grass dividing guide 80 toward the traveling body 2, and the fixing device 90 is disposed between the grass dividing guide 80 and the grass dividing rod 60 in a front view. (See FIG. 6, etc.)

[0163] According to the combine harvester 1 relating to item 14, the fixing device 90 is positioned through the space SP1 between the grass dividing guide 80 and the grass dividing rod 60, through which the planted culms cannot pass when viewed from the front, thereby preventing the planted culms from getting caught on the fixing device and obstructing the transport of the planted culms.

[0164] (Item 15) A combine harvester 1 according to any one of items 1 to 14, comprising a cabin 5 mounted on the traveling body 2, the cabin 5 being positioned offset to either the left or right side from the widthwise center of the traveling body 2, a plurality of the dividers 11 being provided spaced apart in the left and right direction, and the grass dividing guide 80 including a first grass dividing guide 81 attached to a first divider 111 located at the furthest side of the plurality of dividers 11. (See Figures 4, 5, etc.)

[0165] According to the combine harvester 1 of this item 15, the first divider guide 81 attached to the first divider 111, which is the one of the multiple dividers 11 closest to the cabin 5, can prevent the planted culms from falling over (leaning) above the first divider 111. Therefore, during harvesting, the operator can easily check the position of the first divider 111 relative to the planted culms from inside the cabin 5. This allows the traveling body 2 to travel so that, at the start of harvesting, the first divider 111 reliably passes near the side of the planted culms that have been planted in rows.

[0166] (Item 16) The combine harvester 1 according to Item 15, wherein the first grass dividing guide 81 is disposed so that its left-right position does not exceed the end 111b on one side (left side) of the first divider 111. (See Figures 6, 16, etc.)

[0167] According to the combine 1 relating to item 16, when the running body 2 is moved backward, the first grass dividing guide 81 can be prevented from protruding from one end 111b of the first divider 111 and getting caught on the planted stalks.

[0168] (Item 17) The combine harvester 1 according to Item 15, wherein the cutting unit 8 includes a side cover 27 attached to the one side, and the first grass guide 81 is positioned so that its left-right position does not exceed the end 27a of the one side of the side cover 27 (see Figures 4, 16, etc.).

[0169] According to the combine 1 relating to item 17, when the running body 2 is moved backward, the first grass dividing guide 81 can be prevented from protruding from one end 27a of the side cover 27 and getting caught on the planted stalks.

[0170] (Item 18) The combine harvester 1 according to Item 15, wherein the first grass dividing guide 81 intersects with another grass dividing guide 80 (such as the second grass dividing guide 82) arranged on another divider 11 (such as the second divider 112) different from the first divider 111, in a side view (see FIG. 15).

[0171] According to the combine 1 relating to this item 18, in the cutting section 8, the first grass dividing guide 81 can perform a function that the other grass dividing guides 80 (second to fifth grass dividing guides) do not have (the function of preventing planted culms from falling over in the divider 11).

[0172] (Item 19) The combine harvester 1 according to any one of items 1 to 18, further comprising a grass dividing rod 60 attached to the divider 11 and extending toward the traveling body 2 below the grass dividing guide 80, wherein one end 81a of the grass dividing guide 80 is located forward and below the grass dividing rod 60, and the other end 81b is located rearward and above the grass dividing rod 60. (See FIG. 11, etc.)

[0173] According to the combine harvester 1 relating to this item 19, the grass dividing guide 80 can start guiding the planted culms at a position forward and below the grass dividing rod 60, which effectively prevents the planted culms from falling over in front of the divider 11. In addition, the grass dividing guide 80 can guide the planted culms to a position rearward and above the grass dividing rod 60, which allows the planted culms to be smoothly led to the transport path.

[0174] (Item 20) The combine harvester 1 according to any one of items 1 to 19, further comprising a grass dividing rod 60 attached to the divider 11 and extending toward the traveling body 2 below the grass dividing guide 80, and the grass dividing guide 80 is arranged to pass between the divider 11 and the grass dividing rod 60 in a front view. (See FIG. 6, etc.)

[0175] The combine harvester 1 according to this item 20 can prevent the grass-dividing function of the grass-dividing rod 60 from being hindered by the grass-dividing guide 80. Therefore, the grass-dividing rod 60 can be used to divide mainly the base side of the planted culm, and the grass-dividing guide 80 can be used to divide mainly the tip side of the planted culm, thereby achieving good grass-dividing function.

[0176] (Item 21) The combine harvester 1 according to any one of items 1 to 20, further comprising an adjustment mechanism (first adjustment mechanism 95, second adjustment mechanism 96) capable of adjusting the position of the divider 11, and the grass dividing guide 80 moves together with the divider 11 as the position of the divider 11 is adjusted by the adjustment mechanism. (See Figures 20, 21, etc.)

[0177] According to the combine harvester 1 relating to this item 21, even when the position of the divider 11 is adjusted, it is possible to maintain a constant positional relationship between the divider 11 and the grass dividing guide 80. Therefore, when the position of the divider 11 is adjusted, it is possible to maintain good grass dividing and transporting performance without adjusting the position of the grass dividing guide 80.

[0178] Although the embodiments of the present invention have been described above, the embodiments disclosed herein should be considered to be illustrative in all respects and not restrictive. The scope of the present invention is defined by the claims, not by the above description, and is intended to include all modifications within the meaning and scope of the claims.
