As shown in FIGS. 4 and 12, the vertical cutting blade clutch mechanism 85 has an engagement protrusion 81b integrally protruding from the relay shaft 81, and the engagement protrusion 81b can be engaged with and disengaged from the engagement protrusion 81b. The engaging hole 83a formed in the boss member 83 of the swing member 82 and the position of the boss member 83 in the axial direction of the relay shaft 81 are changed so that the engaging projection 81b and the engaging hole 83a are engaged and disengaged. It is comprised with the operation rod 86 to perform.
The boss member 83 is normally urged by a biasing spring 87 provided on the relay shaft 81 toward the clutch engagement side, that is, the side where the engagement protrusion 81b and the engagement hole 83a are engaged.
The operating rod 86 is formed on a part of the pretreatment frame 61 as shown in FIG. 12B in a clutch disengagement operation, that is, in a state where the engagement between the engagement protrusion 81b and the engagement hole 83a is released. It can be fixed in a hooked state with respect to the locking portion 61a.

With the above-described configuration, the vertical cutting device 7 transmits the reciprocating linear motion of the main cutting device 6 to the input interlocking rod 80 as the main cutting device 6 is driven. The reciprocating linear motion is converted into the swing motion of the armband 81a, and becomes the reciprocating rotational motion around the axis of the relay shaft 81 itself.
Then, the reciprocating rotational motion of the relay shaft 81 is converted into the swinging motion of the swinging member 82 and the reciprocating linear motion of the output interlocking rod 84 via the vertical cutting blade clutch mechanism 85, and a pair of left and right cutting blade bodies 71. , 71 reciprocate to cut the target pedicle.
At this time, if it is necessary to drive the vertical cutting device 7, the vertical cutting blade clutch mechanism 85 is turned on, and if it is not necessary, only the main cutting device 63 is driven as a cutting state, and the vertical cutting device 7 is driven. The driving of can also be stopped independently. That is, the vertical cutting blade clutch mechanism 85 constitutes a clutch device capable of intermittently driving the vertical cutting device 7 independently.

The vertical cutting device 7 is arranged on the front side of the machine body relative to the cutting portion of the main cutting device 63 and is behind the front end of the divider 62 provided on the front end side of the pretreatment frame 61. With respect to the upper edge of 62 weeding action surface, the cutting action line CL is arranged in a posture in which the cutting action line CL is orthogonal or almost orthogonal in a side view of the body. The cutting action line CL, as shown in FIG. 5, is the average position of the cutting action point c when the blade edges of the pair of left and right cutting blade bodies 71, 71 intersect each other to cut the target pedicles. The line segment that connects
The relative orientation of the vertical reaping device 7 with respect to the divider 62 is preferably arranged so that the cutting action line CL is orthogonal or substantially orthogonal as described above, but is not necessarily limited to an orthogonal or substantially orthogonal range. It is also possible to change appropriately according to various conditions, for example, the blade front side is configured with an angle of about 80 to 120 degrees with respect to the upper edge of the divider 62 There is no problem.

Further, the vertical cutting device 7 is arranged so that its cutting action line CL is orthogonal or almost orthogonal to the direction of feeding the stalk by the reel type scraping device 64 when viewed from the side of the machine body. At this time, as shown in FIG. 16, it is desirable that the rotation center of the reel-type scraping device 64 be present at a position that coincides with the cutting action portion of the vertical cutting device 7 in a side view.
In this state, with respect to the cutting action line CL of the vertical reaping device 7, the stalk feeding direction by the reel type scraping device 64 and the crossing angle of the upper edge of the divider 62 are almost perpendicular to each other. The cutting action by the vertical mowing device 7 on the heel portion is easily performed satisfactorily.

  Regarding the relationship between the pickup device 5 and the reel type scraping device 64, as shown in FIG. 5, the reel type scraping device 64 seems to be able to scrape the pedicles from the front of the front end of the pickup device 5. It is arranged in relation to. If comprised in this way, before the picking-up operation | work by the pick-up apparatus 5 begins, the scraping action by the reel type | formula raking apparatus 64 will lie down and it will act on a pedicle stick, Therefore It is easy to perform a pick-up work efficiently.

In addition, the cut portion in the left-right direction of the vertical cutting device 7 is provided at a position slightly shifted outward from the center of the weed of the left divider 62, and the stem with the tip side tangled is provided. When weeding, the stalks on the uncut side that have reached the cutting site without untangling are cut at a location slightly outside the center of weeding.
Therefore, when the outer uncut pedicles are cut in this way and the pedicles within the cutting width are cut by the main cutting device 63, the stalks that remain untangled are also reeled. The operation of the device 64, the transfer auger 65, and the like is also added, so that there is little possibility of dropping off from the pre-cutting processing device 6, and it is easy to be fed to the feeder 60 side.
