前周知である。2. Description of the Related Art Conventionally, a rotary mower 3 in which a lower portion of a rotary cover 2 in which a plurality of mowing blades 4 are housed and mounted as shafts and which is an entrance 5 for an object to be cut is provided at the front of the working machine 1. Attached vertically and slidably at the front of the rotary cover 2, a splash prevention plate 6 is vertically slidably mounted in the front-rear direction so as to be slidable. In this case, the cutting edge of the mowing blade 4 hits pebbles and other solids scattered on the ground surface, and the impact causes the pebbles and solids to fly forward with violent force and hit the livestock and buildings in front. The anti-scattering device in the rotary mower that can prevent the occurrence of scatter is known prior to the present application as shown in FIG.

損されるという問題点を有していた。By the way, in the conventional scattering prevention device of this type of rotary mowing machine, the scattering prevention plate for preventing the scattering of pebbles, solids, etc. is simply slid to the rotary cover at the entrance position. It is pivotally attached so as to be free, and a gap of a considerable length is provided between the lower end of the scattering prevention plate and the ground surface. By the way, in the rotary mower, the peripheral speed of the blade edge of the mowing blade is approximately 30 to 60 m /.
S is rotated at a very high rotation speed, so when the cutting edge of the mowing blade that is rotating at a high speed hits pebbles or solids during mowing, the impact causes the pebbles or solids to move forward from the gap. Of course, the splash-prevention plate itself is jumped up to the position indicated by the two-dot chain line due to the scattering force of the scattered pebbles and solids. The gap becomes large and is scattered over a wider area, and there is a risk of hitting livestock, buildings, automobiles, and the like in front. Besides, in the dense flora,
Oversized garbage such as bicycles, large stones, or concrete with reinforced steel are discarded.If the driver does not see it while working, the oversized garbage may be caught in the rotary mower, causing unexpected large There was a problem that the lawn mower was damaged or the accident was caused.

検知装置を提供しようとするものである。The present invention has been made in view of the above-mentioned problems of the prior art, and has an object to solve the problem, for example, that pebbles and solids are affected by an impact action caused by collision with a high-speed rotating mowing blade. Even if a situation such as scattering occurs forward, ensure that the scattered objects are scattered forward and fall down to the ground surface while efficiently mowing without stepping on dense grass. Of course, even if there are oversized garbage or large obstacles in the dense flora, the driver will notice immediately by contact with the detection roll, improving mowing work efficiency and improving safety It is an object of the present invention to provide a detection device which can also be used for preventing scattering in a rotary mower.

A splash prevention plate is slidably hung on the front side of the rotation prevention mower, and the rotary mower slightly behind the suspension position of the shatter prevention plate has a width substantially equal to the cutting width. The roller is suspended so that it can be moved up and down freely in a state where the roller is not grounded.

擲される。Now, a rotary mower is mounted on the front of the working vehicle, and then the detection roller is suspended horizontally above the ground surface so as not to step on the dense grass, and the gauge wheel is moved upward or downward. After adjusting the mowing height and adjusting the mowing height, while rotating the work vehicle toward the embankment slope or playground where the grass is densely grown, multiple mowing blades rotate at high speed, and the densely grassed grass is trampled by the detection roller The blade is quickly cut to a fixed height by the mowing blade rotating at high speed and thrown backward.

草は所定高さ位置で総て刈取られる。By the way, during the mowing operation as described above, if the cutting edge of the high-speed rotating mowing blade hits scattered pebbles or solids, it tends to be scattered forward by its impact operation. However, if a splash prevention plate is suspended from the front side of the rotary mower, or if the rotary mower slightly behind the suspension position of the splash prevention plate, the width is almost the same as the cutting width. Stones and solids that are scattered toward the front higher position due to the high-speed rotation of the mowing blade are scattered forward. Detection stones, solids, etc. scattered toward the lower front side are received by the detection plate, and are allowed to fall to the ground surface without being scattered forward. Because the grass that was densely grown because it proceeds under the state where it does not touch the ground is maintained without being forcibly trampled by the detection roller,
All grass is cut off at a predetermined height.

る。[0008] Further, when obstacles such as oversized garbage such as bicycles, large stones or concrete with reinforced steel are discarded in the flora that cannot be seen during mowing, and the driver cannot confirm the existence thereof. Even if there is, a detection roller having a width approximately the same as the cutting width is rotatably suspended around the front side of the mowing section, so that the grass and the detecting roller can be moved before the grass enters the mowing section. The driver can detect that there is an obstacle in the plexus and stop running by contacting or climbing on an obstacle, so that accidents can be prevented beforehand, for example, even when mowing. Even when performing with dense cloth with large unevenness on the ground surface, the detecting roller that moves forward climbs over the convex part and raises the entire mowing part, preventing the soil of the convex part from being bitten by the mowing part. Can be prevented.

During mowing work, pebbles and solids scattered on the ground surface due to the impact of the high-speed rotating mowing blades are scattered with a violent momentum toward the front high side or low side of the rotary mower. Even in the event of a collision, the pebbles and solids are reliably received by the scattering prevention plate and the detection roller and dropped onto the ground surface, and are prevented as much as possible from hitting humans, buildings, automobiles, or the like in front of the pebble or solids. Is it possible to efficiently perform mowing work while increasing the quality, even if there is large garbage or large obstacles dumped in the dense flora,
It is of course possible to notify the driver accurately by contacting or riding on a detection roller whose width is substantially the same as the cutting width, thereby preventing entrainment in the mowing section and improving the safety of mowing work. Since the detection roller is suspended vertically so that it can be adjusted up and down without touching the ground, the planted grass will not be stepped on. Can be.
