BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention installs a safety cover unit near the top of a cutting unit in order to prevent pebbles and debris from cutting cords rotating at high speed from scattering to the operator of a mower. Moreover, the present invention is for cutting and arranging turf, grass, etc. performed by a cord type mower, and by installing this scattering prevention cover near and parallel to the upper part of the cutting unit of the mower, Due to the rotation and the repulsive action of the cut grass and grass, and the wind pressure generated by the cutting cord, the shatterproof cover surface can move in a stable and parallel manner with respect to the cutting surface, making it easy to mow grass and grass. It can be done.

2. Description of the Prior Art A safety cover of a mower is provided on the rear side of a cutting unit as shown in FIG. 6b so as to correspond to a metal disc blade, and rotates at high speed with respect to the operator of the mower. Insufficient function of the reaping blade to prevent pebbles and shavings from jumping up. Especially in cord-type mowing work, since the turning radius of the cutting cord is larger than that of the metal disc blade, it is necessary to further separate the safety cover from the cutting unit, so the function of the safety cover is greatly impaired, and clothes are soiled during mowing work. In addition, splashing on the face was very dangerous.
In addition, cord-type mowers are not suitable for this work because it is not easy to keep the cutting unit parallel to the cutting surface due to the repulsion of the cutting cord and grass when cutting grass and grass.

Since the attachment position and size of the conventional shatterproof cover are not compatible with cord-type mowers, it is possible to prevent the operator of the mower from jumping up pebbles and vegetation. Since the function is not sufficient, the clothes of the mowing operator become dirty and scattered to the face and the like, which is very dangerous. Also, cord-type mowers are not suitable because it is not easy to mow grass and grass.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention is a safety cover for a cord type mower which is designed to prevent the operator of the mower from jumping up pebbles and fragments of grass and trees. In order to install the shatterproof cover 1 in the vicinity of the upper part of 3, the scatterproof cover 1 is attached to the shaft rod 5 of the mower via the shatterproof cover mounting portion 4. Scattered material is suppressed below the shatterproof cover surface, and since the angle between the shaft and shatterproof cover surface is large, there is almost no jumping up to the operator of the mower, and safe mowing work is possible. . In order to match the usability of the operator of the mower, Fig. 5
As shown in c to c ′, a fitting for adjusting the position is provided at the attachment portion of the shatterproof cover so that the position in front of the shatterproof cover can be adjusted. The shatterproof cover can be made lightweight by using a perforated plate of a size that does not allow the passage of small stones or vegetation, or a net-like metal or synthetic resin to reduce weight and improve workability. In addition, the anti-scattering cover is further improved by bending the front surface slightly upward as shown in A of FIGS. 3 and 4 and by bending the rear part slightly downward as shown in B. The shape of the shatterproof cover is, as viewed from the operator of the mower as shown in FIG. 2, a flat plate having a left and right area slightly wider than the length of the cutting cord normally used from the side to the rear in the rotation direction of the cutting unit, Alternatively, as shown in FIG. 5, by forming a shape that slightly bulges from the wide portion toward the center and the opposite surface bulges slightly from the center toward the periphery, the scattering prevention function is improved. As shown in FIG. 4, scattering can be sufficiently prevented even if it is only on the rotational direction side of the cutting unit when viewed from the operator of the mower, and the weight and operability are improved.

[Effects of the Invention] A scattering prevention cover is installed in the vicinity of the upper part of the cutting unit to prevent scattering and splashing of pebbles and fragments of grass and trees from a cutting cord that rotates at high speed in a mower. Since the angle with the shaft is large, there is almost no jumping up to the operator of the mowing machine, and safe mowing work is possible. In addition, this scatter preventive cover makes it easier to cut grass and grass, which is difficult with cord-type mowers. Since the shatterproof cover surface can be stably moved in parallel, it is easy to trim grass and grass.
