奏するものである。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for discharging aquatic plants on a weed mowing boat that removes and removes underwater and aquatic plants native to lakes and ponds, for example. [0002] A waterweed reaper has a waterweed reaper on the front side.
While self-propelled (advanced), the underwater / water surface weeds are loaded into the front of the carrier conveyor on the ship using the cutting blade of the waterweed mowing machine, and are retained on the carrier. Then, when the aquatic plants are loaded on the bed conveyor, they are transported by self-propulsion to a dumping site such as a revetment or discharged, or discharged to another carrier. Conventionally, the discharge of the weeds was performed from the rear end of the weed harvesting boat. [0003] In the case of a weed harvesting boat that discharges weeds from the rear end, a conveyor dedicated to discharging weeds is required on the rear side. Also, in order to increase the load of aquatic plants,
Due to the balance of the hull, it is necessary to extend the hull rearward.If the hull is extended rearward, the amount of protrusion of the conveyor from the rear end of the hull is reduced, making it difficult to discharge to the revetment and transfer to a carrier. Become. Conversely, if the amount of protrusion of the conveyor from the rear side of the hull is increased, the amount of loaded weeds decreases. In addition, since the hull moves backward to the aquatic plant discharge position while retreating, there is a problem that it is difficult to maneuver the boat. [0004] An object of the present invention is to provide a method for discharging aquatic plants that can solve all of the above problems. [0005] In order to achieve the above object, a method for discharging aquatic plants according to the present invention includes a waterweed reaper on the front side of a hull, and the waterweed reaper is mowered by a cutting blade at a front end. The harvested weeds are loaded into the front of the bed conveyor on the ship by the take-up conveyor, and in the waterweed harvesting boat to be fastened on the bed conveyor, the rear end position of the take-in conveyor can be changed to the upper position and the lower position of the bed conveyor. The take-in conveyor and the bed conveyor are configured to be reversible, and the waterweeds fixed on the bed conveyor on the ship are discharged from the front end of the waterweed reaper by the bed conveyor and the intake conveyor. The method of discharging waterweeds according to the present invention utilizes the intake conveyor of an existing waterweed mower on the front side of the hull, and discharges waterweeds from the front side of the waterweed mower. A conveyor dedicated to discharging weeds is not required. Therefore, it is not necessary to secure the amount of protrusion of the conveyor from the rear end of the hull as in the related art, and the hull can be further extended rearward, and the load of waterweeds increases. Normally, the length of the intake conveyor of the weed harvester is significantly longer than that of the conventional conveyor dedicated to discharging weeds, so if it is used for discharging weeds, the distance between the hull and seawalls or other transport vessels can be increased, and the weeds can be discharged safely. Work can be performed, and the height of the discharge of aquatic plants can be increased,
It is possible to easily discharge the weeds to the revetment and transship to another transport ship, and discharge the weeds to high revetments and large transport ships that could not be discharged conventionally.
Further, since the hull is moved to the waterweed discharging position while moving forward, the maneuvering is simple, and the efficiency of the waterweed removing operation in which the waterweed cutting and discharging are repeated in a relatively short time can be improved. Further, the carrier conveyor can also be integrated, so that the overall structure of the waterweed harvesting boat can be simplified, lightened, and reduced in cost. An embodiment of the present invention will be described below in detail with reference to the drawings. 1 is a cross-sectional side view of a mowing part in a state where a weed is discharged, FIG. 2 is an overall side view of a water-weed mowing boat, FIG. 3 is a plan view of the same, and FIG.

Intake grass conveyor (14)
The rear end position is configured to be changeable to an upper position and a lower position of the loading conveyor (9), and the intake conveyor (14) and the loading conveyor (9) are configured to be reversible. Is discharged from the front end of the waterweed reaper (12) by the loading conveyor (9) and the take-in conveyor (14), using the existing waterweed reaper (12) provided on the front side of the hull, Since the waterweed is discharged from the front side of the waterweed mower (12), a conventional conveyor dedicated to discharging the waterweed is not required. Therefore, it is not necessary to secure the amount of protrusion of the conveyor from the rear end of the hull as in the related art, and the hull can be further extended rearward, and the load of waterweed can be increased. In addition, the intake conveyor (1) of the normal weed harvester (12)
4) Since the length is much longer than the conventional conveyor length dedicated to discharging weeds, if it is used for discharging weeds, the distance between the hull and the seawall or other carriers can be increased, and the work of discharging weeds can be performed safely. At the same time, the height of discharging weeds can be made higher than before, so we can easily discharge the weeds to the revetment and transfer them to other carriers, and also have high seawalls and large carriers that could not be discharged in the past. Can discharge the aquatic plants. Further, since the hull is moved to the waterweed discharging position while moving forward, the maneuvering is simple, and the efficiency of the waterweed removing operation in which the waterweed cutting and discharging are repeated in a relatively short time can be improved. Furthermore, the loading conveyor (9) can also be integrated, and the remarkable effects such as simplification of the conveyer structure, weight reduction and cost reduction can be easily achieved in the whole weed harvesting boat.
