Along with the forward and backward rotation of the stock element aligning plate 1, the stock element part of straw is pushed out to a position where it does not engage with the binding mission case E, and the stock element guide plate 9 pushes the stock element in front of the binding mission case E. To guide you.

Further, as shown in FIGS. 5 and 6, the stock aligning plate 1 is constructed so as to overlap the upper surface of the binding deck 24, and the stock of straw is placed on the binding deck 24 and conveyed. The base part is configured such that the stock pushing plate 1 is pushed forward and backward.

Next, the configuration of the drive unit of the tip side packer 4 will be described with reference to FIGS. 7 to 12.

The tip side packer 4 is fixed to the fixed frame 10 side without sliding for adjusting the long / short culm even when the bundling position is changed by rotating the long / short culm adjusting handle 16.

That is, the tip side packer drive case B is fixed to the input gear box A fixed to the fixed frame 10, and power is obtained from the input gear box A.

Input gearbox A is gearbox 43 and slide shaft 7
And an input shaft 42 and a pair of bevel gear devices. The rotation of the input shaft 42 is changed by the bevel gear device to the front-rear shaft
Has been changed to rotation. The slide shaft 7 is spline-engaged with the inside of the front-rear shaft 8 so as to be slidable, and the rotation is transmitted to the portion of the stock plate aligning plate drive unit C.

A binding clutch arm is provided at the input gearbox A.
A bundling clutch composed of 41 etc. is configured,
The movement of the grain culm sensor provided in the part of the feed chain 14 is transmitted to the binding clutch arm 41 by the Bowden wire, and when the flow of the straw disappears, the binding device is stopped, and when the straw begins to flow, the clutch is re-clutched. It is configured to be joined.

Since the sprockets of the tip side packer drive case B are fixedly mounted on the front and rear shafts 8 of the input gearbox A, the drive arm 37 of the tip side packer 4 is rotated by the chain and the sprocket in the tip side packer drive case B. is there.
The tip side packer 4 is supported by the drive arm 37 and the driven arm 38, and the drive arm 37 is actually driven. However, by changing the support position of the driven arm 38, the tip side packer 4 is rotated. The locus for movement can be changed. The rotation position adjusting bracket 40 is fixedly mounted on the fixed frame 10.

That is, as shown in FIG. 7, the support portion at the other end of the driven arm 38 is connected to the upper and lower pivoting holes 40 of the rotary position adjusting bracket 40.
By changing to either a or 40b, the rotation locus of the tip side packer 4 can be changed to e and f. By changing the rotation locus, it is possible to adjust the conveying speed by delaying the tip portion due to the long and short culms of the grain culm and the difference in dryness of the grain culm.

FIG. 8 shows the positional relationship between the tip side packer 4 and the stocker side packer 2a.

Since the straw root unit has a slightly higher transport speed in the binding posture and the discharging posture, a tidy posture can be obtained. In the present embodiment, the stocker-side packer 2a has an angle a degree only. It is in progress. The angle a is set to about 30 degrees.

(G) Effects of the Invention Since the present invention is configured as described above, it has the following effects.

First, whereas the conventional binding mission case E has a U-shaped configuration, in the present invention,
Since the binding mission case E is arranged in an inverted "U" shape, the tip of the straw is largely engaged with the binding mission case and does not act in the direction of blocking the flow of straw.

Therefore, the tip of the straw is not delayed, and the bundling posture is improved, and the bounced posture after bundling is also improved.

Secondly, if the binding mission case E is arranged at the end on the stock side, the stock source has a high possibility of engaging with the binding mission case E. However, in the present invention, the binding mission is seen from the rear side. The terminal end portion of the stock aligning plate 1 is arranged in the inverted “U” -shaped recess of the case E, and the starting end portion of the stock aligning plate 1 is substantially the same as the end surface of the binding mission case E on the straw passing side. In addition, since it is configured to rotate to a position where it slightly projects toward the straw passage side, the stock base portion that is likely to engage with the binding mission case E can be pushed forward to pass the position where it is not engaged. Of.

Third, by pushing back the root portion of the straw with the stock aligning plate 1, the packer takes in it better, and the straw is better focused in the binding pocket.
