に回転する。The specific installation of the cutter (7) is to place the holder plate (8) on the base (701) of the cutter (701), and place the holder plate (8) on the central base (tol) of a blade-like scraping plate (10) that forms the scraping member described later. with the center of the base (101) facing the holder (
304) and fix the area around the base with bolts and nuts)
(11) and (+2) together with the holder plate (8) and the base (7).
01). As a result, the cutter (7) and scraping plate (10) rotate together with the rotation of the crankshaft.

The scraping plate (10) is provided with a phase shift of approximately 90 degrees with respect to
) facing away from the cutter part (702) of the
The cutting plate (lO) is shorter than the cutter (7),
The rotation locus outer diameter line (A,) of this cutter (7) is smaller by a predetermined width than the rotation locus outer diameter line (B) of the cutter (7), and the locus (A) faces inside and above the locus (B).

。By the way, as shown in the plan view of FIG. 1, the scraping plate (10) rotates the cutter (7) and the scraping plate (lO) clockwise as shown by arrow (a), and to the left in the figure as shown by arrow (b). If the direction of movement is taken as the direction of movement, the upstream edge (10
3) is slid so that the base (+01) is upstream in the rotational direction and the outer scraping part (102) is downstream (wakestream) in the rotational direction, and both sections (
104) and (105) each have a symmetrical planar shape.

せる。The rotation and forward movement of the cutter (7) cuts the grass in the direction of movement, and in this case, the scraping plate (lO), which is coaxial with the cutter (7), also rotates together, and its rotational trajectory (
Since A) is smaller and rearward than the trajectory CB) of the cutter (7), it does not interfere with the grass at the same time as the cutter (7) or before it, and therefore the cutter (7) is removed by the scraping board (10). Therefore, the grass is not pushed down before the mowing action, and the mowing action is performed accurately and reliably.

草だけが衝突し、連続して押し出されることとなる。The grass cut by the cutter (7) faces above the cutter (7), and the scraping part (100 or (105)) of the scraping plate (10) downstream in the direction of rotation faces the cut grass and moves forward. In addition to this, the raking part faces the cutting, and the rotation of this pushes the grass in the right direction, that is, the discharge part (800 direction), and pushes the grass out. Immediately after mowing, the raking section faces this grass, so only unnecessary grass that should be removed collides with it and is continuously pushed out.

る。And the edges (10
3) is slanted and curved as mentioned above, so the grass that collides with it is pushed out to the side by the guiding action of this, and the raking action is carried out smoothly and reliably in conjunction with the above. . When raking grass, the raking member has a blade shape, so there is little resistance, and even a small lawn mower using a low-output engine has little power loss, and a small, low-output engine is sufficient while providing the raking function.

This can be realized with a simple configuration in which the raking members are provided out of phase with each other, and it is possible to improve the performance of conventional small-sized power lawn mowers.
