Further, a PTO shaft is protruded below the knot frame 15, and a chain case 18 is attached to this PTO shaft to drive the star wheel 2 on the right side, the tip star wheel, and the lifting case on the right side.

The star wheel 2 on the right side is rotating in an inclined state with the front side being high and the rear side being low. Reference numeral 14 designates a winding prevention rod for the star wheel 2 on the right side, 8 a stock guide spring on the right side, 5 a stock guide spring on the left inner side, and 6 also a stock guide spring on the left outer side.

In such a configuration, conventionally the auxiliary spring 9
a, 9b were missing, as shown in FIG. It was possible.

The center guide 1 has a surface that transports and guides the stock end of the left grain culm to the star wheel 3 on the left side, a surface that transports the stock end sandwiched between the chain of the stock end horizontal conveyance device 7, and a surface that conveys the stock end of the right grain culm to the star wheel 2. The guide is approximately triangular in plan view and has a surface that guides the guide.

If each part is arranged in a wrapped manner to avoid this blind spot A, each part will be concentrated in close vertical positions, so when a police car collides at a high circumferential speed, each part's engaging part Friction between parts causes the culm to bend due to the lapping margin of the trajectory,
On the contrary, he was putting too much stress on the police cars.

This invention leaves this blind spot A as it is,
Auxiliary springs 9a and 9b are provided below at a position away from the police car 4 to shield this blind spot A from the front and back.

The structure of the auxiliary spring 9 is as shown in FIG. 6, and the front end is composed of a fixed spring plate, and the tip is branched in two directions. The upper auxiliary spring 9b protrudes toward the chain and the tine of the stock horizontal conveyance device 7 and prevents grain culms from entering the blind spot A from this portion. On the other hand, the lower auxiliary spring 9a protrudes toward the front right star wheel 2 and prevents it from entering the blind spot A from the front. Both stock guide springs 5 and 8 have their terminal ends located in front of the pack car locus B.

As shown in FIG. 5, from the top there are a packer 4, a stock guide spring 5, a center guide 1, a left star wheel 3, an auxiliary spring 9b, and an auxiliary spring 9a.
The stock guide spring 8 is located at approximately the same position as the left star wheel 3.

(F) Effect The structure of the present invention is as described above, and the effect will be explained next. The grain culms of the left row are raked in by the left outer stock guide spring 6 and the left star wheel 3, and are held between the stock guide spring 5 and the chain of the stock horizontal transport device 7 and transported to the front of the pack car rotation trajectory B. be done.

However, if the stock guide spring 5 is brought too close to the rotation locus of the patscar, it will damage the culm, so the culm will be damaged only halfway. Lead to trajectory B.

The same goes for the right side, where it is held between the right star wheel 2 and the stock guide spring 8 until halfway, but the stock guide spring 8 comes to an end midway, and after that it is held between the auxiliary spring 9a provided below and the right star wheel 2. transported between.

(g) Effects of the invention Since the invention is constructed as described above, it has the following effects.

First, center guide 1 and star wheel 2
, stock horizontal transfer device 7 and Patscar rotation locus B are,
Since they are arranged in a concentrated manner, if they are arranged overlappingly, the damage to the grain culm will be severe, so a certain amount of spacing is provided between the tips, but this spacing creates a blind spot A in this part.

If the grain culm is located inside the blind spot A, it will not be caught by any conveying device, resulting in backflow or stagnation of the grain culm.

In the present invention, by providing an auxiliary spring 9 in this part, it is possible to eliminate the accumulation of culms in blind spots.

Second, by arranging the auxiliary spring, it was possible to prevent the grain culm from entering the blind spot without disturbing the overall flow of the grain culm.
