[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water mower that cuts and removes water plants native to lakes and ponds.

[0002]

2. Description of the Related Art Conventionally, there has been a technique in which a mowing section having a cutting blade and a take-in conveyor is mounted on the front side of a barge, and a mowing operation is performed while the barge is advanced.

[0003]

According to the above prior art, water grass is taken into the mowing part by forward movement of the barge. Therefore, in the working state where the water grass floating near the water surface moves due to wind or sea, etc., the grass is harvested and taken. Work cannot be performed efficiently.

[0004]

According to the present invention, a cutting blade is provided at a starting end of a take-in conveyor, and a waterweed mowing machine that lifts the waterweed cut by the cutting blade by the conveyor is provided with a cutting blade in front of the cutting blade. The conveyor is provided so as to be able to move up and down, the width of the conveyor is smaller than the width of the cutting blade, and the width of the scraper is smaller than the width of the conveyor. Therefore, even when the waterweed is easily moved by wind or sea, etc., the waterweed can be forcibly taken in by the raking reel into the catching area of the cutting blade and the starting end of the conveyor, and the conveyer of the conveyor is larger than the cutting width of the cutting blade. Since the take-in width has been reduced, a wide range of aquatic plants can be cut and collected and taken in. Also, since the take-in width of the reel has been made smaller than the take-in width of the conveyor, the weeds have extended laterally near the water surface. Also be one in which cutting position the aquatic plants is easily prevented by give disturbed, and may be easily carried out, such as aquatic plants winding prevention to reduce and reels of the reel driving force.
