The motors are driven by hydraulic motors (37) and (38) provided separately in b).

[0012] According to the above, the aquatic plants harvested by the reaper are lifted by the lifting conveyor (4). At this time, pebbles, shells and the like accumulate on the horizontal blade (5a), and poor harvesting occurs. May occur. Therefore, in the present invention, the above pebbles, shells and the like are prevented from collecting on the horizontal blade (5a). The horizontal blade (5a) shown in FIG. 1 is attached to the mounting table (39), and the rear end of the mounting table (39) is L
The lower part of the cutting frame (41) is provided so as to be bent downward in a letter shape and form a certain space (40) therewith. This space (40) is provided over the entire length between the left and right mowing frames (41), and forms a discharge hole for pebbles, shells and the like. A cutting frame connecting plate (42) having a substantially trapezoidal cross section is provided between the left and right cutting frames (41) to secure rigidity. Further, on both sides of the left and right cutting frames (41), the side plates (1) having the net (12) shown in FIG.
There is 3).

As described above, the rear end of the mounting base (39) is bent and formed in an L-shape, and the connecting plate (42) having a substantially trapezoidal cross section is provided between the left and right cutting frames (41). In addition, the rigidity of the portion constituting the discharge space is secured, and the pebbles, shells, and the like flow out smoothly. By the way, in the waterweed harvesting boat as described above, the harvested waterweed is conveyed backward by the conveyors (6) and (7) and discharged directly to the ship or the like, but the waterweed contains a lot of water. Therefore, both the weight and the volume are large, and the transportation becomes very burdensome. Therefore, as shown in FIG. 2, the support (47) is attached to the frame (44) of the discharge conveyor (43), which is the rear unloading conveyor.
And the lower end of the rod (46) of the hydraulic cylinder (45) are attached. The lower end of the rod (46) is pivotally supported on the frame (44) so as to swing about the mounting portion, and the support (47).
The frame (48) of the compression conveyor (49) is pivotally supported on the upper end of the cylinder, and the hydraulic cylinder (45) is
Install. With the above configuration, the compression conveyor (49) swings as indicated by an arrow by the operation of the hydraulic cylinder (45), and can be dehydrated by sandwiching water plants between the compression conveyor (49) and the discharge conveyor (43). Can be configured.
Dehydrated aquatic plants have less water and their volume is reduced, so loading them on boats etc. does not burden them.

The discharge conveyor of the waterweed harvesting work boat shown in FIG. 6, that is, the rear transport conveyor (7) can move upward as shown by a chain line, but does not move downward. However, when it is possible to work in reverse, it is necessary to move downward, but at this time, the driven side is swung downward by a hydraulic cylinder with the drive side of the discharge conveyor as a pivot point. Design is possible. By designing in this way, it is possible to attach an attachment to the rear part and work in reverse, and also to raise the weeds to some extent without an attachment.
Weed weeding can be done with the rear attachment.
FIG. 3 shows a discharge conveyor (rear transfer conveyor).
(7) A device capable of moving up and down, and a conveyer with a raising tine having the same structure as the raising device for combine (50)
Are attached to form a weaving device for floating grass. In general, the work boat shown in FIG. 6 can cut algae with roots with a reaper, but those floating on the water surface, such as water hyacinth, cannot be cut just by pushing with the reaper. The work boat can be moved forward and backward by the paddle wheel (2) by arranging the above described weeding device at the rear. Can collect weeds. Therefore, it can respond to any aquatic plants. It is to be noted that the scribing device (50) for floating weeds is designed so as to be able to be lifted upward when moving forward.

[0015] In addition, a handrail is required for a work boat to be able to walk safely on board and to perform inspection equipment. Boarding a work boat moored at the pier,
At the time of disembarkation, the paddle wheel cover (55) is used, but there is little space, and it is easy to slide, and there is no handrail and there is no place to grab, so there is a problem from safety. Therefore, foldable hand rules are provided on the bow and stern of the hull as shown in Figs. I do.
Specifically, the mounting bracket (5) is attached to the bow and stern on the hull (1).
1) is mounted, and an arched pipe (52) is pivotally supported on the apparatus, and an expanded metal (53) is stretched between the arched pipe (52) and the horizontal pipe (54). Therefore, if this is made horizontal, it can be used as a step, and if it stands up, it becomes a guard. As a result, safe work on the water is enabled, and boarding and disembarking can be performed safely. In any case, the present invention is characterized in that a space for discharging pebbles, shells and the like is provided behind the horizontal mount.

[0016]

According to the present invention, the cutting frame connecting plate is erected between the left and right cutting frames in front of the lifting conveyor and the rear end of the horizontal blade mounting base is bent to form the cutting frame connecting plate. Rigidity can be secured even if a space for discharging pebbles, shells, etc. is provided below and over the entire length between the left and right mowing frames between the rear end of the horizontal blade mount and the lower portion of the mowing frame. Pebbles, shells, etc. on the upper surface smoothly fall out of the space from the discharge space,
Because it does not accumulate on the horizontal blade, it does not result in poor harvesting.
