Abstract

(57) [Summary] [Purpose] A workboat for collecting algae is equipped with a paddle wheel with less entanglement of aquatic plants on the ship side. Therefore, it was necessary to remove the paddle wheel when transporting the work boat by land. [Structure] A paddle wheel 2 is attached to one end of a support frame 7, the other end is rotatably pivotally supported on a deck, and a drive device for raising and lowering the support frame, for example, a hydraulic cylinder 9 is provided, and a work boat is installed. A work vessel for collecting algae that can be mounted on a truck. The figure shows a state in which the paddle wheel 2 is pivotally held on the deck so that it can be mounted on a truck tower.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 Regarding the improvement of algae recovery work vessels for cutting and recovering aquatic algae that grow in rivers, lakes and ponds.

[0002]

[Prior Art]

 In this type of work boat, a paddle wheel with less entanglement of water plants was attached to the side of the ship, and the hull was propelled by the reaction force generated by the rotation of the paddle wheel. Due to the nature of the work, the work place is often moved, and the main movement is land transportation by truck.

[0003]

[Problems to be solved by the device]

 When transporting by land, place a board on the land, and use a crane to lift the work boat from the surface of the water and drop it temporarily. Remove the paddle wheel and place the work boat within the width of the truck bed and place it on the truck with a crane.

The procedure for landing the work boat on the water surface again after the land transportation is the reverse. The paddle wheel is attached and detached manually, which requires labor and time. While the work boat is temporarily placed on land and the paddle wheel is removed, it is a waiting time for the crane. In addition, a temporary storage place for work boats is always required, and it is often difficult to secure a temporary storage space on a road with heavy traffic or in a narrow space.

[0005]

[Means for Solving the Problems]

 A paddle wheel is attached to one end of the support frame, and the other end of the support frame is pivotally supported on the deck by a shaft that is parallel to the side edge of the hull and at a predetermined distance, and is used to raise and lower this support frame. A drive device is installed, and the support frame is laid down on the deck when propelling the hull, and the support frame is erected and the paddle wheel is held on the deck during land transportation so that the width of the work boat fits within the width of the truck bed. It is a work ship for collecting algae.

[0006] Further, in the work vessel for collecting algae, the raising / lowering device for the support frame is a hydraulic cylinder that connects the support frame and the hull.

[0007]

[Action]

 When a workboat is to be transported by land to move to a work site, the tilting drive is operated on the water surface to raise the support frame and hold the paddle wheel above the deck. Next, the work boat is hoisted from the surface of the water with a crane and placed directly on the truck. The procedure for suspending a work boat after land transportation on the water surface is the reverse.

[0008]

【Example】

 FIG. 1 is a side view of a work vessel for collecting algae of the present invention. 1 is a hull of a work boat, 1'is a lateral edge of the hull, 2 is a paddle wheel, 3 is a mower, and 1-dotted line shows a state in which the mower is pulled up into the water when the work boat is moved. 4 is a conveyor and 5 is a conveyor side plate.

2 is a view taken along the line AA of FIG. 1, FIG. 3 is a view showing a state in which the paddle wheel of FIG. 2 is rotated and stored on the deck, and FIG. 4 is a side view of FIG. 6 is a hydraulic motor for driving a paddle wheel, 7 is a supporting frame having a paddle wheel with a hydraulic motor mounted at one end, and the other end is rotatably supported on a deck 10 by a shaft 8. Reference numeral 9 is a hydraulic cylinder of the tilting drive device.

In the above embodiment, the tilting drive device is shown as a hydraulic cylinder, but it is not limited to this, and one embodiment thereof is shown in FIGS. 5 and 6.

FIG. 5 shows an example in which an erecting device in which one end of the rope 11 is connected to the support frame 7 and the other end is wound around the powered rope winder 12 is equipped.

[0012] Fig. 6 shows still another example in which a tilting drive device driven by a hydraulic motor or an electric motor 13 is provided.

FIG. 7 is a front view of a cross-section of a hull showing a propulsion unit of a conventional algae recovery work boat, and FIG. 8 is a view showing the hull mounted on a truck. A conventional example is shown in which the frame 7 is detached and reattached, and the width of the hull is stored in the width of the bed of the truck.

[0014]

[Effect of the device]

 When the propulsion device for a work boat according to claim 1 is used, the paddle wheel of the work boat can be lifted above the hull deck above the surface of the water and directly mounted on the truck by a crane or landed directly onto the surface of the water. It not only saves a lot of labor and time required for transportation, but also removes and installs the conventional paddle wheels and pedestals, set up a place to temporarily put a work boat on land, trouble finding a place, and waiting time for a crane. As a result, the transfer cost will be significantly reduced.
