[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a raking reel mounting device for an aquatic plant reaping boat, which can rake aquatic plants on the surface of the water while moving on the surface of the water, and cut and accommodate the plants.

[0002]

2. Description of the Related Art Conventionally, a mowing part provided with a cutting blade at a front part and a conveyor at a bottom part is mounted on a front part of a machine body so as to be vertically movable by pivoting about a rear pivot point. In the aquatic plant harvesting boat configured by disposing a vertically movable raking reel in front of the reel, the rotation fulcrum of the reel lift arm that supports the raking reel and moves up and down is a rotation fulcrum of the mowing unit. It was provided at the front of the lift arm for the reaper, which was farther away.

[0003]

However, in such a structure, when the mowing part is lowered below the water surface and the raking reel is raised above the water surface, the raking reel separates to the front side of the mowing part and is scraped. It is possible to extend and retract the reel lift arm or slide the base of the reel lift arm to the reaper lift arm to make it movable.However, such a device is complicated. And the operation becomes complicated.

[0004]

SUMMARY OF THE INVENTION The present invention has been devised so as to solve such a problem and to make it possible to operate effectively with a simple structure. A support arm is vertically provided from a base side portion of the section lift arm, and a lower portion of the support arm below the support arm which is close to the rotation fulcrum is supported by a lifting arm for lifting and moving the reel. It is configured by providing a rotation fulcrum.

[0005]

Therefore, when cutting aquatic plants deepening below the surface of the water, the cutting unit rotates the lift arm for the cutting unit downward to lower it below the surface of the water, and the raking reel rotates the lift arm for the reel. In this case, since the pivot point of the lift arm for the reel is located below and near the pivot point of the lift arm for the mowing unit, the raking reel is located at the front of the mowing unit. As a result, the aquatic plants can be effectively scraped into the cutting section.

Pivotally connected to the upper portion of both brackets 13 so as to be rotatable about a pivot point P1.
The cutting section A can be moved up and down by a hydraulic cylinder 14 interposed between the intermediate section of the conveyor 10 and the aquatic plants sent out from the end section of the conveyor 2 fall above the start end side of the conveyor 10 in the related art. It is configured in the same manner as in the case of the first embodiment, except that a support arm 3a is vertically provided from a base side portion of the lift arm 3 which is located forward in the vicinity of the rotation fulcrum P1.
The rear end of the lift arm 4 for both reels, which supports the raking reel B approaching the front and moves up and down and bends and extends rearward, is located below and below the pivot fulcrum P1. Hydraulic cylinders 15 for lifting and lowering the reel are interposed between the lift arm 4 for the reel and the lift arm 3 for the reaper, respectively, and are pivotally connected to the lower portion of the arm 3a so as to be rotatable about the rotation fulcrum P2. And configure.

Therefore, when cutting aquatic plants deepening below the water surface W, as shown in FIG. 1, the cutting unit A rotates both lift arms 3 downward and lowers them deep below the water surface W, The scraping reel B must raise both the lift arms 4 above the water surface W by rotating the lift arms 4 upward. In this case, the rotation fulcrum P2 of the lift arm 4 moves downward below the vicinity of the rotation fulcrum P1 of the lift arm 3. As a result, the raking reel B moves upward while approaching the front of the reaping unit A, and the reaping unit A is slightly moved upward as shown in FIG. Even if it is located on the upper side, the raking reel B can be made to approach the front part of the reaping section A in the same manner as described above, so that the aquatic plants can be raked into the reaping section A effectively.
