A pair of left and right scraping wheels 9, 9 are pivotally supported by a polygonal rotating shaft 10, and an elastic guide rod 12 and a guide 13 whose bases are fixed to the upper pipe 11 constituting the horizontal frame are attached to the side surface. As seen, it detours around the rotating shaft 10 from above to below and extends rearward while approaching the guide plate 8.

A root leveling device 14 having an embodiment described below is disposed on the stock end side of the focusing path 3. That is, the root leveling device 14 has a front portion that is connected to the straw conveying device 7.
It faces the rear end in side view and is bent outward, and the rear end extends to a position above the stock receiving plate 15 corresponding to the rear end in the front-rear direction (in the direction of the culm of the collected waste straw). A root leveling plate 16 is provided (orthogonal direction),
In order to swing the root leveling plate 16 back and forth in the direction of the culm,
Links 17, 17 pivoted on its back (Figure 3)
are pivotally connected to support shafts 19, 19 erected on a mounting frame 18 which can be slidably fixed to the pipe 11 described above to form a parallel link shape, and one of the links 17 is connected to the rotating shaft 10. It is constructed by connecting an eccentric wheel 20 fitted so as to be slidable laterally to an internal operating rod 21 via an arm 17a, and the mounting frame 18 is provided with a suitable locking tool 22, and this By the release operation, the entire root leveling device 14 can be adjusted to move in the direction of the rod, for example, to the positions A and B shown in dotted lines in FIG.

As shown in FIGS. 3 and 4, the above-mentioned root leveling plate 16 includes an upper edge and a lower edge of a flat plate 16a that is erected facing the stem end of the focusing path 3. A regulating piece 16b for preventing the stock head from floating and a regulating piece 16c for preventing the stock head from popping out downward, which are respectively oriented toward the panicle side of the stem culm, are each set to have a reciprocating width greater than or approximately equal to this. Form a protrusion.

And, the above-mentioned regulation piece 16c for preventing stock capital from jumping out.
An arm is provided close to the upper surface of the guide plate 23 which extends from the mounting frame 18 so that the regulating piece 16c can reciprocate with the stock receiving plate 15 and has a width wider than the width L of the reciprocating movement. 24 is provided integrally. Further, the edge of the panicle side of the guide plate 23 is bent downward 23a to prevent the end of the plant from entering the lower surface of the guide plate 23 when the guide plate 23 is laterally adjusted. .

As a result, the root leveling plate 16 is reciprocated, and when the base of the stem culm that is scraped into the focusing path 3 by the packer 4b or the like is struck and aligned, the root leveling plate 16 moves back and forth.
The regulating piece 16b properly guides and regulates to prevent the stock from floating when the stock is bent upward and moves away from the stock a, and the regulating piece 16c is arranged between the flat plate 16a and the stock receiving plate 15. It is possible to prevent the end of the plant from protruding and entering into the reciprocating movement space formed in the space and becoming a nuisance due to being pinched between them, and the guide plate 23 is set in a predetermined relationship with the root leveling plate 16. Since the guide plate 23 is integrally provided with the stock end floating, the guide plate 23 properly guides the stock end to the flat plate 16a side, and prevents the end of the regulating piece 16c from pushing the stock end out of order or preventing the stock end from being pushed out. While preventing troubles caused by the stem culm entering between the receiving plate 15 and the flat plate 16a, the flat plate 16a can effectively tap the end of the plant and achieve a good root alignment effect.

When the binding device 2 is moved to adjust the binding position (states A and B in Figure 4), or when the root leveling device 14 is moved to follow this to adjust the length of the stem culm, The guide plate 23
moves integrally close to the stock receiving plate 15,
Since the relationship between the root leveling board 16 and the guiding plate 23 for good root leveling does not change, troubles caused by stem culms sneaking in between them or between both and the stock receiving plate 15 can be avoided. Therefore, no matter which position the root leveling device 14 is moved and adjusted, a good root leveling effect can be achieved, and the binding work can be carried out in a convenient manner.

Reference numeral 25 shown in FIG. 3 is a door rod for receiving the stock, and the free end thereof is directed rearward in the bundle release direction at the end of the root leveling plate 16 of the root leveling device 14 and attached to the mounting frame 18. It is rotatably supported on a support shaft 26 provided obliquely, and is provided so as to be tiltable toward the rear by means of a tension spring 27 and a stopper 28, and to maintain the upright return posture.

The door rod 25 is provided inwardly close to the flat plate 16a and located at a portion corresponding to the terminal end of the focusing path 3.

Therefore, in its upright position, the door rod 25 configured as described above, with the stem culm being pushed into the convergence path 3 by the packer 4b etc. and received by the door 4, is placed near the root leveling plate 16. The root leveling board 16 is used to catch the roots and prevent them from hanging backward or slipping.
It is possible to make the root alignment effect effective, and to perform a good tying operation without causing tying mistakes etc. with the culms aligned.

Furthermore, when the door 4 detects a certain amount of culm to perform binding, and the sweeper 4c releases the bundle to the rear, the door rod 25 moves backward against the spring 27 by the stock bundle. The door rod 25 is tilted to open the bundle path 3, but at this time, the door rod 25 retreats while rotating toward the plant end in a direction away from the stem culm around the obliquely installed support shaft 19, so that the bundle is released. To promote a good release action of the bundle without giving much resistance when the bundle is released, and to prevent the stock of the bundle from being brought in when returning to a standing position immediately after release. It is something that can be done.

Next, the structure of the stem culm receiving plate in the above-mentioned binding device will be explained with reference to FIGS. 4 to 6.
Reference numeral 30 denotes a panicle receiving plate 30 which is disposed opposite to the stock receiving plate 15 described above on the side of the stem and culm with the tubercle 5, door 4, etc. in between. ) and extending along the focusing path 3 in a substantially horizontal or slightly downwardly sloping manner.

On the other hand, the flat stock receiving plate 15 provided closer to the stock side is installed diagonally so that it becomes lower than the panicle receiving plate 30 as it reaches the lower side in the bundling release direction. The convergence path at the rear portion is configured to become larger downward.

As a result, as shown in Fig. 6, the culm diameter is large, the weight is large, and the bulky stock head can be transported more smoothly in the condensed state, and the stock base end is slightly lowered. While the stem culm is accommodated in the convergence path 3 comfortably and comfortably,
The tied bundle that has been tied and is about to be released can be smoothly released without receiving much resistance from the stock receiving plate 15, and the next focusing path 3 which is in an unbound state with the released bundle can be smoothly released. This makes it easy for the stem culm in the area to separate quickly, allowing for a large release distance with an appropriate release posture.

Reference numeral 31 denotes a focusing guide installed upright on the stock receiving plate 15, and its upper edge 31a is brought close to the side of the door 4 to form a focusing path 3 which is substantially parallel in side view between it and the knotter guide 5a. Therefore, the focusing guide 31
By providing this, there is an advantage that it is easy to install the stock receiving plate 15 formed in a backward downward position without making any major changes to the existing bundling device 2, and this focusing guide 31 appropriately covers the return path of the pack car 4b. , it is possible to accurately prevent the stem culm from being sent backwards or brought in by the packer 4b.

Incidentally, reference numeral 12a is a guide rod whose base is attached to the binding device 2 and guides the stem and culm stock between the stock receiving plates 15.

In the above-mentioned bundling device 2, the waste straw discharged from the terminal end of the waste straw conveying device 7 falls onto the downwardly inclined part of the front part of the guide plate 8, and is scraped while being guided by the guide rods 12, 12a and the guide plate 13. It is scraped into the scraping locus of the packer 4b by the clippers 9, 9, and the packer 4b scrapes it into the focusing path 3 and focuses it, and the door 4 senses that the amount of focusing has reached a certain amount and When the rotating clutch is engaged, the needle 4a and the knot 5
The straw bundles are activated and knotted, the sweeper 4c releases the straw bundles rearward while removing the knots, and the bundle discharger 6 discharges the straw bundles diagonally to the rear of the mown field.

In the above-mentioned series of bundling and releasing operations, the base of the stem culm is leveled and rooted by the root leveling device 14 configured as in the embodiment, and the stem culm is aligned with the panicle receiving plate 3.
While being supported by the stock receiving plate 15, the door rod 25 always maintains the proper position, so that good bundling and release can be promoted even more smoothly.
