The left and right alignment rollers (40) and (40) are rotated inward from each other through the left and right bevel boxes (42) and (42).

The belt transmission device (7) is directly connected to the alignment roller (40) with the left brush portion, and the input pulley (7b) of the belt transmission device (7) is the alignment roller with the left brush portion. A belt transmission device (7a) is attached to the roller shaft of the roller (40), and the input pulley (7b), the output pulley (7c) and the belt (7a) wound around both pulleys ( 7).
Further, an input sprocket (8b) is attached to the other end of the intermediate shaft (7d) that attaches the output pulley (7c) to one end, and the chain transmission device (8) is connected to the other end. Yes.
The chain transmission (8) transmits power to the input sprocket (8b) and an output sprocket (8b) and the spiral feeder is constructed from a take-Hung Chen (8a) to the sprockets (5) Yes.

As shown in FIGS. 1, 2, 3 and 6, a pair of stem tension belt bodies (6 a ), (6 a) is arranged, the pair of stem tension the belt body (6 a), (start end of the flop of 6 a) - in Li, a pair of stems tensile passive flop in example - Li (6c), the (6c) The left and right pulley shafts (6e) and (6e) to be attached to the shaft are extended downward, and a pair of left and right rough foliage cutting blades (6f) and (6f) are attached to the respective pulley shafts (6e) and (6e). The outer peripheral edge portions are provided so as to partially overlap on the conveyance center line, and are rotated inwardly toward the passage side of the foliage portion , respectively, toward the start end side. It has become.
Further, each of the pulley shafts (6e) is extended downward, and a pair of left and right speed increasing chain devices (44) and (44) are mounted, and the stem blades are connected via the speed increasing chain device (44). The transmission mechanism is configured to drive the peripheral speed of (45) several times faster than the conveying speed, and each speed increasing chain device (44) is composed of a drive sprocket (47), a passive sprocket (48) and a chain. The passive sprocket (48) is made smaller than the drive sprocket (47) to increase the speed.
