【Example】

 Hereinafter, the present invention will be described based on embodiments shown in the drawings. First, the aquatic weeding work vessel will be described. In FIGS. 6 and 7, (1) is a float hull with a hollow structure arranged on the left and right sides, and (2) is the left and right sides of the hull (1) at the center of the hull. A paddle wheel for propulsion, (3) a water weed reaper mounted on the front of the hull (1) to reap aquatic plants such as algae that grow in water, and (4) a cutting blade (5) in the reaper (3). ) A lifting conveyor that lifts the waterweeds harvested by the above to the upper part of the front of the hull (1), and (6) was lifted with the feeding start end under the feeding end of the lifting conveyor (4). The front transport conveyor that transports water plants to the front-rear center position of the hull (1), (7) faces the feed end of the front transport conveyor (6), and the feed end is at the rear of the hull (1). The rear transport conveyor extended to (8) is fixed in the approximate center of the hull (1). It is a driver's cab equipped with an engine (9), a driver's seat (10), a driving control unit (11), etc., and is cut by the cutting blade (5) during the propulsion of the hull (1) by the rotation of the paddle wheel (2). The aquatic plants are pulled back and conveyed by the conveyors (4), (6) and (7).

The reaper (3) has a bottom part formed by the lifting conveyor (4) and left and right side walls formed by side plates (13) having a net body (12) to form a gutter-shaped whole and the front end face thereof. A horizontal blade (5a) and left and right vertical cutting blades (5b) are arranged on the inside of this, and a kite-shaped aquatic plant intake (14) is opened inside. Then, the hull (1) is movably supported by a lift link (17) via a fulcrum shaft (15) and a lifting cylinder (16), and the reaper (3) is shown in a working position and phantom lines shown in FIG. It is provided so that it can be moved up and down as needed in the storage position.

Further, a fixing member (19) approximately in the front and rear of the rear conveyor side plate (18) for supporting the rear conveyor (7) is connected to the rear end surface of the hull (1) via an elevating cylinder (20). As shown in the phantom line in Fig. 6, when the cylinder (20) is operated to raise the feed end of the conveyor (7) together with the side plate (18), it can be transferred to another carrier. It is configured to be

Further, the transportation speed (V2) of the rear transportation conveyor (7) is set to be slower than the transportation speed (V1) of the front transportation conveyor (6) so that the rear transportation conveyor (7) moves to the rear transportation conveyor (7). When the plants are inherited, the plants are configured so that more plants are loaded on the rear transport conveyor (7) while the plants are compressed due to the speed difference.

Furthermore, the left and right outpost lights (21) are attached to the outermost lower ends of the left and right side plates (13) to facilitate the discovery of aquatic plants from the driver's seat (10). The other (23) shows the storage lid of the weight storage unit for balance provided at the rear of the hull, which is attached to the fixed bracket (24) so as to be openable and closable. Four horizontal control floats (28) are installed on the front, rear, left and right outside of the hull (1), and the float up / down control cylinder (31) is mounted on the cylinder mounting plate (29) fixed to the hull (1). The float (28) is attached to the tip of the piston rod (30). When the sensor (32) detects the forward / backward / leftward / rightward inclination of the hull (1), the cylinder (31) is appropriately controlled to move the float (28) into and out of the water to keep the hull (1) horizontal. ..

Further, each of the conveyors (4), (6) and (7) is formed of a mesh belt whose both sides are connected to a chain, and hydraulic motors (33) (34) (35) provided on the respective feed end sides. ), While the paddle wheel (2) is supported by the hull (1) via the lifting device (36) with adjustable support height, and the hydraulic modules are separately provided on the left and right wheels (2a) (2b). It is designed to be driven by data (37) (38).

[0012] According to the above, the waterweeds mowed by the reaper are lifted by the hoisting conveyor (4), but at that time, shells and pebbles may accumulate on the horizontal blade (5a), resulting in poor cutting. is there. This plan prevents the above shells and pebbles from accumulating on the horizontal blade (5a). The horizontal blade (5a) shown in FIG. 1 is attached to the mounting base (39), but the rear end of the mounting base (39) is bent downward in an L shape to form a constant space (40). The lower part of the mowing frame (41) is formed so that The space (40) is provided over the entire width of the frame. The space above forms the discharge holes for pebbles and shells, and the cutting frame connecting plate (42) is attached to the portion corresponding to the space of the cutting frame (41) to ensure rigidity. The frame connecting plate (42) has a trapezoidal cross section and is attached over the entire width of the frame. On both sides of the frame (41) are side plates (13) having the mesh body (12) shown in FIG.

As described above, since the rear end of the mounting base (39) is bent into an L-shape, rigidity is ensured, and pebbles and shells flow out smoothly together with the connecting plate (42). By the way, in the above weed cutting work vessels, weeds are transported backward by conveyors (6) and (7) and discharged directly to boats, etc., but they contain a lot of water. Therefore, the weight and volume are large, and the transportation becomes a heavy burden. Therefore, as shown in FIG. 2, the support (47) and the lower end of the rod (46) of the milling machine (45) are attached to the frame (44) of the discharge conveyor (43) which is the rear unloading conveyor, and the rod (46) is centered around the attachment portion. The lower end is pivotally supported on the frame (44) so as to swing as, and the frame (48) of the compression conveyor (49) is pivotally supported on the upper end of the column (47), and the hydraulic cylinder (45) is also supported on the frame (48). Install. With the above configuration, the compression conveyor (49) swings as indicated by the arrow by the operation of the hydraulic cylinder (45), and water plants can be sandwiched between the discharge conveyor (43) and the dehydration device (43) to dehydrate. To do. Since dehydrated aquatic plants have a small amount of water and their volume is reduced, loading them on a boat is not a burden.

The discharge conveyor of the water weeding work vessel shown in FIG. 6, that is, the rear transfer conveyor (7) can move upward as shown by a chain line, but cannot move downward. However, when it is possible to work in reverse, it is necessary to allow it to move downward as well, but at that time, there is a design that swings the driven side downward with a hydraulic cylinder with the drive side of the discharge conveyor as the pivot point. It is possible. By designing in this way, it is possible to work backwards by attaching the attachment to the rear part.Also, it is possible to pull up the weeds to some extent without the attachment. be able to. In the structure shown in FIG. 3, the discharging conveyor (7) can be moved up and down, and a conveyor (50) with a raising tine having the same structure as that of the combine raising apparatus can be attached to the floating weeding apparatus. .. In general, the work boat shown in Fig. 6 can harvest rooted algae with a reaper, but it cannot remove algae such as water hyacinth that are floating on the water surface because they are pushed by the reaper. Therefore, the work boat can move forward and backward with the paddle (2) by arranging the above-mentioned weeding device in the rear part. You can grass. Therefore, any aquatic plant can be used. However, the forward drafting device (50) is designed so that it can be pulled upwards when moving forward.

Further, a work rail requires a handrail in order to be able to safely walk onboard and be equipped with inspection equipment. In addition, the paddle wheel cover (55) is used when boarding or disembarking on a work boat moored at the pier, but there is little space and it is easy to slip. There is no handrail and there is no place to grab, so there is a problem from safety. .. There are foldable handrails on the left and right sides of the bow and stern of the hull, as shown in Fig. 4 and Fig. 5, so that they can be used as a step when boarding or disembarking, and they can be raised upward during work to prevent falling guardrails. To use as. Specifically, mounting brackets (51) are installed on the bow and stern of the hull (1), and an arch pipe (52) is pivotally supported on this, and an expanded metal ( 53) is installed. Therefore, if this is horizontal, it can be used as a step and can be used as a guard when standing up. As a result, safe water work is possible and it is possible to board and disembark safely. In any case, the present invention is characterized in that a space for discharging pebbles, shells, etc. is provided behind the horizontal mount.

[0016]

[Effect of the device]

 According to the plan, a space for discharging small stones, shells, etc. is provided between the rear end of the horizontal blade mount and the lower part of the mowing frame over the entire width of the mowing frame. The pebbles and shells on the table will not fall out of the discharge space to the outside of the ship and will not accumulate on the horizontal blade, so there will be no poor harvesting.
