Further, at the right end portion of the third rotation shaft 37, the second rotation is provided via the connecting members 42, 42 between the first and third rotation shafts 35, 37 and the coaxial fifth rotation shaft 39. A fourth rotation shaft 38 coaxial with the shaft 36 is connected. The fourth rotation shaft 38 is provided with four pairs of fingers 24b perpendicular to the fourth rotation shaft 38 so as to protrude from the outer peripheral surface of the drum 25 by being shifted by about 90 ° in the radial direction of the drum 25, and at the center. All the fingers 24b _{1 to} 24b ₄ of the insertion portion 28 are coaxially arranged, and at least two other individual fingers 24b are positioned between each pair of fingers 24b.

  Further, at the right end portion of the fifth rotation shaft 39, connecting members 42, 42 are interposed between the first, third and fifth rotation shafts 35, 37, 39 and the coaxial seventh rotation shaft 41. Thus, a sixth rotation shaft 40 coaxial with the second and fourth rotation shafts 36 and 38 is connected. On the right end side of the sixth rotation shaft 40, the right outermost finger 24c is connected to the sixth rotation shaft 40 at a right angle. The right end portion of the seventh rotation shaft 41 is pivotally supported on the auger right support wall (not shown) of the platform 15 and is connected to the auger transmission mechanism (not shown).

That is, each finger 24 a, 24 b, 24 c has a base end portion attached to each tightening member 43, and a tip end portion thereof can be projected and retracted from a finger insertion hole 33 formed in the drum outer peripheral surface of the scraping auger 19. doing.

  Then, as shown in FIG. 5, the front finger 24 can act on the harvested grain while projecting, and the rear finger 24 is inserted into the internal auger 19 so that each finger 24 a, 24 b , 24c act on the harvested grain while drawing a circular trajectory in a side view.

  As described above, the drum 25 that is aligned within two pitches of the receiving blade 22 from the outermost effective receiving blade 22 at the left end portion of the main cutting blade device 3 in a plan view in FIG. 3 and a front view in FIG. 4. At least one finger 24a is provided at the position, so that even if the cereal is scraped by the tine 32a near the left end of the take-up reel 17 on the divider 16 side and cut by the main cutting blade device 3, Since the finger 24a at the position acts so as to take in the tip part of the cereal, the picking efficiency can be improved.

  In addition, four pairs of fingers 24b are arranged in the central scraping portion 28 where the blades 29a and 29b are not present so as to be shifted from the outer peripheral surface of the drum 25 by being shifted by approximately 90 ° in the radial direction of the drum 25, and Since all the 28 fingers 24b1 to 24b4 are arranged on the same axis, it is possible to efficiently lead out the culm that has been scraped by the tine 32 and cut by the main cutting blade device 3 to the platform 15.

  In addition, between each pair of fingers 24b and 24b, at least two other individual fingers 24b are arranged and a predetermined distance is provided between the fingers 24b and 24b. Even if a large foreign matter is taken in, only the foreign matter passes between the fingers 24b and 24b, and the foreign matter is not forcibly sent out into the feeder house 14, so that it is possible to prevent the take-in auger 19 and the platform 15 from being damaged. .

  Next, the structure of the divider 16 as a weed body will be described in detail. As shown in FIG. 6, the divider 16 is disposed in front of the main cutting blade device 3 and at the front end portions of the left and right side walls of the platform 15, protrudes in front of the side end portion of the cutting portion 2 of the combine A, and removes the weeds. In order to make it easy to do, it is pointed (a quadrangular pyramid having approximately three shapes in side view). Further, the front end portion of the divider 16 is chamfered and formed in a curved shape in a side view.

  Further, the dividers 16 and 16 are arranged in a positional relationship such that the scraping reel 17 is sandwiched from the left and right as shown in FIG.

  The dividers 16, 16 are disposed at a position slightly higher than the cutting frame 44 that forms the bottom of the platform 15, and inner guides 50, 50 are disposed facing the inner side surfaces of the left and right dividers 16, 16. Yes. The inner guides 50 and 50 are formed in a rod shape, are connected to the lower side near the front end portion of the dividers 16 and 16, and extend horizontally in a side view toward the rear, and the rear end portion of the divider 16. It is composed of an inclined portion 52 that gently bends upward from the vicinity to the upper portion of the main cutting blade device 3 by bending.

  In plan view, the horizontal portion 51 is inclined toward the rotation support bodies 45, 45 of the take-up reel 17, while the inclined portion 52 is substantially directly below the rotation support bodies 45, 45. It extends to the device 3 side.

  By configuring the inner guide 50 in this way, the tip portion of the cereal that has been scraped by the scraping reel 17 is scraped to the platform 15 side and cannot be scraped by the scraping reel 17. Also in the corn flour located between 45 and the divider 16, the corn flour is guided by the horizontal portion 51 of the inner guide 50 toward the take-up reel 17 while being weeded by the divider 16.

  The tip part of the corn straw guided to the take-up reel 17 side is taken into the platform 15 side along the inclined part 52 of the inner guide 50. In addition, in order to efficiently scrape the culm guided to the scraping reel 17 side by the inner guide 50, the outermost tine 32a and the inclined portion 52 are configured as close as possible.

  Moreover, the inner guide 50 is not guided to both ends where the main cutting blade device 3 does not move in order to cut the tip side from the midway part of all the weeds that have been weeded and scraped, It is configured so that the culm is reliably guided within the range in which the main cutting blade device 3 is effectively movable.

  As described above, the inner guide 50 is provided on the inner side surface of the divider 16 on the left side at least so as to bring the grain on the end side within the cutting range defined by the pair of dividers 16 and 16 to the inside. It is possible to urge the cereals in the non-scratching area generated between the outermost tine 32a in the vicinity of the left end portion of the take-up reel 17 and the inner surface of the divider 16 to the take-up reel 17 side. The range of culms can be scraped efficiently and reliably, and in particular, it has a great effect on cereals that have fallen on the divider side.

  Moreover, it is possible to prevent cereals from staying between the side wall and the inner guide 50 on the end side where the main cutting blade device 3 is not movable.

  Furthermore, by providing the inner guide 50 on the inner side surfaces of the left and right dividers 16, 16, it is possible to reliably take in cereal grains in which the range of cut is defined by the dividers 16, 16.

  Here, the combine A according to the present embodiment has an inner divider 53 disposed near the front end portion of the left side wall of the platform 15 connected to the divider 16 and below the inclined portion 52 of the inner guide 50. Specifically, the inner divider 53 is formed in a tubular shape, is disposed in front of the main cutting blade device 3, has one end connected to the lower end of the inner wall on the front side of the left side wall of the platform 15, and the other end Is slightly inserted so as to cover the tip of the receiving blade 22 of the main cutting blade device 3 closest to the inclined portion 52 outside the inner guide 50 (center side of the traveling machine body 1).

  That is, as shown in FIG. 3, the inner divider 53 extends from the front side of the left side wall of the platform 15 to the tip of the rear receiving blade 22 while intersecting the inclined portion 52 of the inner guide 50 in a plan view. Further, the axial direction of the receiving blade 22a covered with the tip is configured to be the direction of the left outermost tine 32a in plan view.

  By disposing the inner divider 53 in this way, it is possible to prevent the intrusion of the cereal into the cutting blade 23 that does not contribute to cutting, and between the inner guide 50 and the inner surface on the divider 16 side where the inner guide 50 is provided. It is possible to prevent the harvested culm from staying, and the culm in a region where it cannot be raked between the rotary support 45 located at the left and right ends of the scraping reel 17 and the inner surface of the divider 16. Even so, it can be reliably guided to the main cutting blade device 3 for cutting.

  Therefore, it is possible to make the culm biting by the inner guide 50 more reliable by the inner divider 53.

  The inner divider 53 may be disposed in the vicinity of the front end portion of the right wall as a similar configuration.

  The preferred embodiments of the present invention have been described above. However, the present invention is not limited to the specific embodiments, and various modifications and changes can be made within the scope of the gist of the present invention described in the claims. It can be changed.
