[0013]
The branch cases (79) are respectively provided on the upper rear side of the pulling case (60) to drive the pulling tine (59) of the case (60). The upper end of the case (60) is connected, and an output shaft (85) is provided at the lower end of the case (60) to drive the tine chain (84) of the tine (59). (80) is connected to the lateral drive shaft (78) via a pair of bevel gears (86), and the lower end is connected to the output shaft (85) via a pair of bevel gears (87). 60) and the driving tine (59) is driven.
[0014]
The tip transport bodies (72), (73), and (74) are connected to and supported by the lower ends of the second and third branch cases (79) from the left side and the second from the right side, and these transport bodies (72) ( 73) (74) input shafts (81), (82), (83) are linked to each output shaft (85) via a universal joint (88), and each tip conveying tine (72a) (73a) (74a) Each of these is driven.
[0015]
Thus, in the plan view, the tip carrier bodies (72), (73), and (74) are arranged at the opposing positions of the upper carrier bodies (64), (66), and (68), and the respective tines (64a) that are in the mutually opposed relationship. (72a) · (66a) (73a) · (68a) (74a) by making the feeding direction the same direction, the pulling action force to the rear of the cereal hook that has been raised and hooked on the case (60) is large At the same time, the tip transporting tines (72a), (73a) and (74a) transport the position slightly below the neck of the cereal to reduce degranulation, and also cause each tip transporting near the lower position of the drive case (77). The bodies (72), (73), and (74) are arranged so that the pulling action force of the cereals hooked on the drive case (77) is increased, and the upper and lower parts transport bodies (63) to (68) Smooth transport of cereals without catching in the Y-shaped transport path (89) to be formed It is obtained by configured to enable.

【The invention's effect】
In the present invention, the tip carrier bodies (72), (73), and (74) are arranged at the opposing positions of the upper carrier bodies (64), (66), and (68), and the respective tines (64a) and (72a) that are in the mutually opposed relationship. ), (66a), (73a), (68a), and (74a) are set to the same direction to increase the pulling action force of the cereals that are pulled up and hooked on the case (60) to the rear. The tip transporting tines (72a), (73a) and (74a) transport the position slightly below the neck of the cereal to reduce degranulation, and each tip transporting body ( 72) (73) (74) are arranged to increase the pulling action force of the cereal hook caught on the lateral drive case (77), and formed by the upper and lower parts conveying bodies (63) to (68). Smooth transfer of cereals without catching on the Y-shaped transport path (89) It can become.
