刈地に起立放置せしめられるのである。Since the bundled waste straw discharging device according to the present invention is constructed as described above, its operation will be explained next with reference to the above-mentioned embodiment. The bundled waste straw is conveyed backward upward and toward the mown field, and is dropped and released from the end of the conveyance in an approximately vertical upright position with the plant base facing downward. The solid line in Figure 1 also indicates No. 4.
The bundled straw falling guide body 19 is biased and held in the guiding position shown by the chain line in the figure, that is, the bundle is formed into a substantially U-shape and is in a vertical position so as to be able to closely surround the terminal end of the conveying device 18. The conveying device 1 is moved by the waste straw falling guide 19.
Regardless of the impact when released from the end of 8, the bundled and removed straw will be guided to fall vertically, so it will always remain in an upright position or become upright. The posture of the plant is changed and the plant is allowed to fall onto the mowed field, and the plant is left standing on the mowed field with the stem part spread out in a conical shape.

おそれは皆無である。At this time, since the lower end edge of the falling guide 19 is located above the bundled waste straw that stands up on the cut ground, as the combine 2 moves forward, the bundled waste straw that has been left upright can be removed from its tip portion. There is no possibility that the falling guide body 19 will interfere with the falling guide body 19 and fall down.

したがって、圃場には、結束排わらが順次円錐状に拡散

変位せしめて、結束排わらの詰まりを未然に防止する。However, in the bundled waste straw discharging device 8 according to the present invention, the falling guide body 19 is energized and held at the guiding position where it can guide the bundled waste straw to fall as described above. When the waste straw is about to become clogged, the waste straw is bundled and the falling guide 19 is moved around the pivot shaft 20 against the tension spring 26 to reduce the distance between the end of the conveying device 18 and the falling guide 19. By rotating and displacing it in the direction that dogs can tighten (direction A), clogging of the bundled waste straw is prevented.

そして前記結束排わらが落下せしめられると、落下案内

作用位置を設定できて、有利である。Further, the guiding position where the falling guide 19 can guide the bundled waste straw to fall, and therefore the distance between the end of the conveying device 18 and the falling guide 19, is set appropriately in advance according to the properties of the bundled waste straw. However, instead of the guiding action position regulating pin 240 in the above embodiment, as shown in FIG. 32, and if the adjustment bolt 30 is configured to arbitrarily adjust the position where the tension spring 26 of the drop guide 19 is held, the properties of the bundled waste straw, such as large or small volume, can be adjusted according to the soft shell. This is advantageous because it is possible to set the most appropriate guiding position of the fall guiding body 190 depending on the conditions of the culm and the like.

用効果を奏しうるのである。In the above-described embodiment, the bias retaining means for biasing and retaining the drop guide 19 at the guiding position is constituted by the tension spring 26 and the guiding position regulating pin 24 (or adjustment bolt 30). However, in other implementations, as shown in FIGS. 7 and 8, for example, the fixing pin 33 is attached to the drop guide 10 (or support 19a), and the stopper pin 34 is attached to the anti-wrapping body 16 (or chain case 9). ) may be configured to be held under pressure by a spring plate 36 attached to the spring plate 35. In this case, when the bundled waste straw is about to become clogged, the retaining pin 34 is released from the spring plate 36 by the spring plate 36. It comes off against the pressure holding force, and the falling guide 19 returns to the guiding position (seventh position).
The guide is rotated from the solid line position in the figure to the non-guiding position (the chain line position in the figure), and the same effects as in the above embodiment can be achieved.

富むものである。In any case, as is clear from the above explanation, the bundled waste straw discharging device of the present invention reliably transports the bundled waste straw dropped from the bundled waste transport device to the field in an upright position. In order to leave the bundled waste straw alone, that is, to guide the bundled waste straw to fall in the vertical direction in an upright position, the bundled waste straw falling guide body, which is provided in close proximity to the conveyance end of the conveyance device, is normally operated by an appropriate biasing and holding means. The bundled waste straw is energized and held in a guiding position where it can be guided to fall, and if the bundled waste straw becomes unexpectedly stuck between the end of the conveying device and the falling guide, the bundled waste straw is removed. Since the structure is such that the falling guide can be moved to a position where the clogging can be prevented, the bundled waste may accidentally become stuck between the end of the conveying device and the falling guide, causing various problems.
