[Cutting part: Drop guide member]
As shown in FIGS. 5 to 7, a plate-shaped drop guide member is provided at a portion covering a region extending from a part of the front surface of the lower end portion of the main frame 25 to a part of the horizontal frame 26 connected to the main frame 25. 65 is provided. The drop guide member 65 is attached to the harvested grain culm K that is cut by the reaping device G and conveyed by the conveying device H, and moves behind the intermediate frame 30 at the front of the horizontal frame 26. It has a function of dropping into the open space S, and is provided in an inclined posture that is forwardly lowered in a side view. The drop guide member 65 is a steel plate having a smooth surface, but a resin plate may be used.

  In the horizontal frame 26, two members, a left frame 26L on the left side and a right frame 26R on the right side, are arranged on the coaxial core, and are connected to each other by a bolt at the flange connecting portion 26A and in the vicinity of the flange connecting portion 26A. The connecting portion 26B is formed. The flange portion 25A at the lower end of the main frame 25 is bolt-connected to the connected portion 26B, and the driving force from the transmission shaft inside the main frame 25 is applied to the connection portion to the transmission shaft inside the horizontal frame 26. A bevel gear mechanism (not shown) for transmitting to is installed. An opening 65A is formed at the lower end of the drop guide member 65 in order to avoid contact between the flange connecting portion 26A and the connected portion 26B.

  The upper end of the flange portion 25A at the lower end of the main frame 25 is connected to the lower end of the first support member 66 that is inclined toward the rear toward the upper end, and the upper end of the right frame 26R is further to the rear. The lower end of the second support member 67 in an inclined posture that inclines toward is connected. The first support member 66 and the second support member 67 are provided in a parallel posture, and a drop guide member 65 is disposed on the front side of the first support member 66 and the second support member 67, and the drop guide member The drop guide member 65 is connected by inserting a screw 68 through a long hole 65H formed in 65 and screwing it into a nut portion of the first support member 66 and the second support member 67. The long hole 65H is formed in a vertically long shape, and the long hole 65H is configured so that the mounting position of the drop guide member 65 can be adjusted in the vertical direction.

  The drop guide member 65 is a position below the position where the transport path of the second transport mechanism H2 joins the transport path of the first transport mechanism H1, and the lower end portion of the harvested grain culm K transported by the transport device H ( The position of the upper end 65 </ b> B of the drop guide member 65 is set so that the cutting portion) contacts the upper end 65 </ b> B of the drop guide member 65. As shown in FIG. 6, when the planted grain culm J is cut by the reaping device G, sent to the rear as the reaped corn culm K, and then conveyed by the transport device H, the reaped cereal culm K is sent rearward and obliquely upward, and the lower end Ka (cutting portion) moves along a movement locus L shown in FIG. Accordingly, by setting the relative positional relationship so that the upper end 65B of the drop guide member 65 protrudes slightly above the movement trajectory L, the lower end Ka of the harvested culm K is brought into contact with the upper end 65B of the drop guide member 65. Yes.

  Since the fall guide member 65 is arranged in this way, when the deposits such as straw and grass adhering to the harvested cereal mash K naturally fall, the deposits follow the upper surface of the fall guide member 65. It is sent to the open space S and falls to the field scene in front of the horizontal frame 26. Moreover, even if the deposits such as straw and grass are in a state where it is difficult for them to fall naturally, they fall due to vibrations that occur when the lower end Ka of the harvested culm K comes into contact with the upper end 65B of the drop guide member 65 as it is conveyed. Thus, the deposit is sent to the open space S along the upper surface of the drop guide member 65 and falls to the field scene in front of the horizontal frame 26. This eliminates the inconvenience of depositing straw or grass on the upper surface of the horizontal frame 26 or the front part of the main frame 24, and does not cause the inconvenience that the accumulation grows and obstructs the conveyance of the harvested cereal mash K.

  Further, by setting the position of the upper end 65B of the drop guide member 65 high, it becomes possible to efficiently remove the deposits of the harvested cereal mash K, but when this upper end 65B is set high, the harvested cereal The conveyance resistance of cocoon K increases, and it leads to the inconvenience which disturbs the conveyance attitude | position of the harvested grain culm K. The amount of straw and grass varies depending on the working environment. Therefore, in a work environment where there is a large amount of straw, grass, etc., setting the position of the upper end 65B of the drop guide member 65 to a high value may cause some inconveniences such as an increase in conveyance resistance acting on the harvested cereal mash K and disturbance in conveyance resistance. It is also configured to be able to select a setting that efficiently removes deposits while allowing.

[Operation / Effect of Embodiment]
From such a configuration, when performing a harvesting operation, even if the planted culm J is lying down in an intertwined state, the weed culm 61 can be well weeded and the pulling device 22 can be caused. The planted culm J caused by the pulling device 22 is scraped by the scraping mechanism, and at the same time when the stock is cut, the transport by the first transport mechanism H1 and the second transport mechanism H2 is started. It is sent in a state in which the harvested cereal mash K of the second transport mechanism H2 joins the path along which the harvested mash K is transported by the first transport mechanism H1. Since the drop guide member 65 is disposed at a lower position of the merging portion, even when the straw and grass attached to the harvested cereal mash K are separated from the harvested mash K and dropped at the merging position, By dropping the drop guide member 65 from the open space S in front of the horizontal frame 26 to the field scene, straws, grass and the like are not deposited on the upper surface of the horizontal frame 26 or the upper surface of the main frame 25. In particular, when the harvested grain culm K passes through the junction, the upper end of the drop guide member 65 comes into contact with the cut part of the harvested grain culm K. It is possible to shake off straw and grass by dropping off or oscillating the harvested cereal mill K, and this also eliminates the inconvenience of depositing straw and grass on the upper surface of the horizontal frame 26 and the like.

  When the harvested cereal mash K conveyed by the conveying device H is nipped and conveyed by the supply conveying chain 43, the stocker side is lifted by the guide rod 54, so that it is in a sideways posture, and the stocker is supplied to the feed chain FC. In this way, when the harvested culm K is delivered to the feed chain FC, it will be detached from the rear end of the sandwiching rod 50, so that it will fall into the non-pinch state and easily fall off from the rear end of the sandwiching rod 50. is there. However, since the auxiliary clamping body 56 presses the harvested cereal mash K against the supply transport chain 43 and the cover body 55, dropping of the harvested cereal mash K is suppressed.

  Next, when the harvested grain culm K is supplied to the threshing device D by the feed chain FC, the tip portion is detached from the first tip transportation unit 44 and the slimming of the harvested grain culm K is supplied to the supply transport chain 43. It moves along the upper surface of the relay material 58 while sliding on the upper surface of the upper cover body 55. During this movement, the intermediate portion of the relay material 58 is likely to hang downward due to the weight of the harvested grain culm K, but a support plate 57, an auxiliary plate 57A, and an auxiliary bracket 6A are disposed below the relay material 58. Therefore, the drooping of the intermediate part of the relay material 58 is suppressed, and the harvested cereal mash K can be smoothly fed from the supply guide plate 6 to the cereal supply port 5 to perform the threshing process.
