As shown in FIG. 4, the reel blade (15) is connected to the reel shaft (
Both ends of 1) are rotatably supported by bearings 6), and the rotation of the seventh gear (14) is transmitted to the reel shaft (1) by a drive transmission mechanism (16!) such as a pulley, belt, or gear. It is transmitted and rotationally driven.The reel shaft il+ is fixed to both ends of the reel shaft il+ by welding or the like so as to be perpendicular and concentric to a disk-shaped stationary plate (27j ri-jshisuke tl).Blade support The plate (2) is fixed at the base end to the fixed plate c with screws with a predetermined angle shift at both ends of the reel shaft +11 in response to the twist of the blade (6), and the blade support plate (2)
) A Vi blade mounting surface 3) is formed at the tip, and a male threaded portion (6) projects perpendicularly from the plate mounting surface (3). A through hole (6) is perforated at both ends of the blade (3), and the blade (3) is twisted to form a fixed blade t20.
An angle (approximately 20°) is created between the through hole (6) and the male screw part (6), and the nut (7) is tightened to attach it to the guide support plate (2). There is. In addition, the blade (3) is cut out at a portion other than the cutting edge (4) so that the average cross section becomes smaller from both ends toward the center, making it easier to bend at the center. For example, the cutting edge of the Monoke blade (3) shown in Figure 6 (
Cut out the spine (8) on the opposite side of 4) in a parabolic shape and insert the notch (
9). As shown in Figure 7, when cutting out the spine (8) of the plate (3) in a parabolic shape, the notch is wave-shaped, and the depth of the notch (9) is such that the center of the blade (3) is deep. This is what I did. The one shown in FIG. 8 has a plurality of holes (
28), and the opening area of the hole 8) increases from both ends of the blade (3) toward the center. In the blade shown in FIGS. 9 and 10, the thickness t of the blade gradually decreases from both ends toward the center.

As described above, in the present invention, the central part of the blade is easy to pinch, so even if a large external force is applied, such as when a stone is caught between the reel blade and the fixed blade, the blade will flex. This has the advantage of preventing deformation and damage.
