Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a weed cutting machine for cutting and removing water plants that grow naturally in lakes and ponds.

[0002]

2. Description of the Related Art Conventionally, there has been a technique in which a mowing section equipped with a mowing blade and a take-in conveyor is equipped on the front side of a pontoon, and the pontoon is moved forward to perform mowing work.

[0003]

SUMMARY OF THE INVENTION In the above-mentioned prior art, when aquatic plants conveyed by a conveyor are stored on a pontoon, the aquatic plants are bulky and the amount of water retention of the aquatic plants is large, resulting in a heavy weight. It cannot be stored easily, so it is necessary to frequently perform the work of reloading the aquatic plants on the pontoon, or the work of moving the pedestal to the shore to drop the aquatic plants, etc. Had a working problem.

[0004]

SUMMARY OF THE INVENTION Therefore, the present invention is a weed reaper that takes in aquatic plants cut by a cutting blade by a conveyor, and is provided with a pressurizing means for compressing the aquatic plants taken in by the conveyor. Since the aquatic plants are compressed by the pressurizing means to make the aquatic plants bulky and the water retention amount of the aquatic plants is reduced to make the weight lightweight, the amount of aquatic plants that can be stored on the pontoon can be easily increased and stored on the pontoon. It is possible to easily reduce the number of operations for dropping aquatic plants on a carrier or shore, and to easily improve the efficiency of harvesting aquatic plants and the workability of post-treatment of a harvested aquatic plant.
