Description

[Detailed Description of the Invention] [Field of Industrial Application] This invention relates to an aquatic plant collection vessel, and more specifically to a vessel for collecting buoy-shaped aquatic plants, and in particular, for efficiently collecting water hyacinth. This relates to a waterweed collection vessel equipped with a rotary conveyor and a cutter.

[Prior art]

Conventional aquatic weed collection vessels have been known to use a conveyor system, for example, which is equipped with a belt conveyor tilted at the front end of the vessel, and moves forward while lowering it into the water to scoop up floating matter onto the belt conveyor. It is being However, in the above-mentioned conveyor type aquatic weed collection vessel, as the vessel moves forward, the belt conveyor pushes the water away, so floating objects do not get on the belt conveyor and escape to the left and right water surface areas at both ends of the belt conveyor, making it impossible to collect them effectively. There are drawbacks.

That is, it becomes extremely difficult to place free floating objects on the belt conveyor as the speed relative to the water increases and as the rotation speed of the belt conveyor increases.

For this reason, belt conveyors have a problem in that their loading capacity is low and efficient work cannot be expected.

In addition, Russell-type and vacuum-type aquatic weed collection vessels are also known as aquatic weed collection vessels, but Russell-type aquatic weed collection vessels do not have the ability to collect aquatic plants, and simply cut aquatic plants into small pieces. It simply blows this out to the left and right water surface areas,
Not only is it not an effective method for aquatic plants that still have a strong reproductive capacity even if they are reduced to small pieces, the current situation is that small pieces of rotten aquatic plants become sludge that settles to the bottom of the water and causes water pollution. .

On the other hand, in a vacuum type aquatic weed collection boat, a hose with an opening at the other end is attached to the absorption side of the aquatic weed collection pump, and the opening at the end of the hose is pressed against the water surface where aquatic plants are growing, and the aquatic plants are sucked into the pump. Although this method uses forced force to scoop up water and transport it via a pump, it has the disadvantage that an amount of water that is about 10 times the amount of aquatic plants collected must be sucked up at the same time as the aquatic plants.

Furthermore, due to the nature of the pump itself, it is not possible to pump air.
The operation is extremely delicate and impractical, and conventional collection vessels have not been able to effectively collect aquatic plants.

[Purpose of the invention]

This invention was devised by focusing on the conventional problems, and its purpose is to cut the aquatic plants to an appropriate length into a shape that is easy to pull up, and then remove the buoy-shaped aquatic plants from the water surface. A low cleaner with a conveyor that allows efficient collection to the collection section.

- Provides a waterweed collection vessel with a cutter set.

[Structure of the invention]

In order to achieve the above-mentioned object, this invention has a function of mowing, cutting, and rearwardly feeding aquatic plants, which is installed between the floating bodies at the bow of a ship consisting of a pair of left and right floating bodies with a passage for collecting aquatic plants in the center. A rotary cutter equipped with a rotary cutter is provided, and a collector is connected to the rear side of the hull to collect the aquatic plants fed by the rotary cutter, and the aquatic plants cut close to the rotary cutter are sequentially placed in the passage for collecting aquatic plants. The gist of this is that a conveyor for unloading cargo to be transported to a collector is provided.

Further, the gist of the present invention is that the rotary cutter is of a separate type.

Furthermore, the present invention provides that a rotary cutter is provided between the central floating bodies in the longitudinal direction of the hull in addition to the bow of the ship, and the unloading conveyor is provided in close proximity to the rotary cutter provided between the central floating bodies. This is a summary.

[Embodiments of the invention]

Hereinafter, the present invention will be described in detail based on the accompanying drawings.

FIG. 1 shows a perspective view of a conveyor-equipped rotary cutter type aquatic weed collection vessel in which the present invention is implemented, and this conveyor-equipped rotary cutter type aquatic weed collection vessel is composed of a cutter vessel A and a collector B.

The hull 10 of the cutter ship A has a pair of left and right floating bodies 11a.
The floating bodies 11a and Ilb are connected in the width direction by a bridge J3 to form an integrated structure.

The passage port 14 of the passage 12 is open in the shape of a funnel, and can guide aquatic plants into the passage 12 in the same range as the width of the hull IO.

The bow portions of the floating bodies 11a and 11b are equipped with a rotary cutter 15 that has the function of mowing, cutting, and feeding aquatic plants backward. The aquatic plants collected by the rotary cutter 15 are a passageway.

12, and is housed in a collector B which is connected to the rear of the cutter ship A by a connecting rope 16 so that film can be deposited thereon.

The rotary cutter 15 is composed of a blade 17 that directly cuts and cuts aquatic plants, shafts 1 and 8 that fix the blade, and a drive section 19 that rotates the shaft 18.

To connect the rotary shaft 18 to which the blade 17 is fixed and the drive section 19, an endless rubber belt 20, a chain belt, or the like may be used as an intermediate medium, or a direct shaft drive method may be used.

The rotating shaft 18 to which the blade 17 is fixed is configured to rotate in the same direction as the traveling direction of the hull 10. With this configuration, the rotary force consisting of the blade 17, the rotating shaft 18, and the drive unit 19 can be used to trim and cut aquatic plants that are floating and growing in the water area in front of the water area in the direction of travel of the ship's hull 10. , and can be sent to the rear.

In FIG. 1, the rotary cutter 15 is connected to the left and right floating bodies 1.
Although it straddles 1a and llb and forms a single entity,
As shown in FIG. 2, the middle part of the rotary cutter 15 is separated to create independent left and right rotary cutters 15.
(separate rotary cutter) and placed at the front of each of the floating bodies 11a and llb, there is no difference in its function of cutting, cutting, and sending aquatic plants to the rear in the same way as the integrated rotary cassota 15.

In addition, the shape of the blade 17 is not an upright type, but a blade type with a curved blade 17 from the blade base tVa to the blade edge 17b, as shown in FIGS. It is possible to prevent aquatic plants from getting entangled with the blade 17 and the rotating shaft 18.

The blade 17 can fully demonstrate its ability with a thin plate, but when more fine pieces of aquatic plants are required in the effective utilization treatment of aquatic plants, a sharp blade is attached to the blade cutting exception peripheral part 17C. You can anobu the ability to cut aquatic plants.

The number of blades 17 is determined by the length of the rotary wheel 18 of the rotary cutter 15 (the width of the hull 10) and the type of aquatic plants to be collected.

The blade 17 may be fixed to the rotating shaft 18, but in order to facilitate maintenance, inspection, and replacement of the blade 17,
It is convenient to use a connection type in which a socket 23 having a bolt hole 21a is fixed to the rotating shaft 18, a blade 17' having a similar bolt hole 21b is inserted into the socket 23, and the two are connected with a bolt/nut (not shown). It is.

Furthermore, even if the blade 17d has a shape in which only the tip of the blade 17 is bent to one side (as shown by the chain line in FIG. 4), the effect is the same as that of the planar blade 17.

The attachment of the blade 17 to the rotating wheel 18 is performed by attaching the blade 17 to the rotating shaft 18.
It is sufficient to attach one blade 17 to each cross section, but when the purpose is to collect more fragmented aquatic plants, the effect can be expected by attaching two or three blades 17 to one cross section. can. Note that it is preferable that the blades 17 are arranged so that they are not installed at the same position in the cross section.

Further, unlike other parts, the implantation density of the blades 17 is increased in the parts near both ends of the rotating shaft 18. This is to make the cutting and separation of the collected aquatic plants and the aquatic plants that escape to the rear outside of the hull 10 more effective.

As already mentioned in the prior art section, it is difficult to capture floating objects with a belt conveyor, but the continuous conveyance ability of the belt conveyor is fully recognized as having its advantages.

Therefore, this invention makes it possible to capture floating objects by adding improvements to the belt conveyor.

That is, in order to compensate for the disadvantage that when the hull 10 moves forward, the belt conveyor displaces water and floating objects do not get on the belt conveyor, as shown in FIGS. A rotary cutter 15 is provided.

- In other words, in the passage 12 for collecting aquatic plants immediately after the rotary cutter 15 provided at the bow of the floating bodies 11a, 11b, in the vicinity of the rotary cutter 15, and the collector B
A cargo unloading conveyor 60 connected to the vehicle is arranged at an angle.

In addition to the ability to mow and cut aquatic plants by involving them, the rotary cutter 15 has a curved blade 17 to reduce force of backward feeding. The cargo is placed on an improved unloading conveyor 60.

Next, in order to compensate for the drawback that it becomes extremely difficult to place free floating objects on a belt conveyor as the water velocity increases, the improved unloading conveyor 60 does not use a flat belt and is shown in FIG. And a mensch belt 61 as shown in FIG. 7 is used.

This allows aquatic plants to be placed on the mensch belt 61 without the mensch belt 61 itself interfering with the flow of water.

In other words, the mesoscopic belt 61 has no relation to the water velocity. Furthermore, in order to compensate for the drawback that as the number of rotations of the belt conveyor increases, it becomes more difficult to place free floating objects on top of it, the mensch belt 61 is provided with a tip that serves to catch and hold aquatic plants. A catcher fin 62 formed in a figure 7 shape is attached. Moreover, the catcher fin 62 is not a flat plate, but is rod-shaped so that it does not push water forward when it is underwater. By using the catcher fin 62 in the shape of a 7-shaped rod (various shapes are possible as long as it is rod-shaped), aquatic plants can be reliably placed on the improved unloading conveyor 60 without being affected by the belt rotation speed. can.

The drive source 64 of the improved cargo unloading conveyor 60 may be directly connected to the rotating shaft 63, or the rotating shaft 63 and the drive source 64 may be connected by a medium such as a rubber belt or a chain belt.

In addition, as shown in FIG. 5, the rotary cutter 15 is
In addition to the rotary cutter 15 (referred to as the front rotary cutter), a rotary cutter 15a having the same specifications as the rotary cutter 15 ( It may also be equipped with a rear rotary cutter (referred to as a rear rotary cutter).

Of course, the front rotary cutter 15 alone can demonstrate its ability for cutting and rearward feeding of aquatic plants, but by arranging the rotary cutters 15' and 15a in two stages at the front and rear, aquatic plants can be cut into smaller pieces. This allows for smoother rearward feeding, allowing it to fully demonstrate its capabilities as an aquatic weed collection vessel.

In the case of a double rotary cutter type ship, which is equipped with a rear rotary cutter 15a in addition to the front rotary cutter 15, the improved unloading conveyor 60 is placed not immediately after the front rotary cutter 15 but at the rear rotary cuff 158. placed immediately after.

The cutter ship A has a propulsion device 25 so that it can self-propel, and this propulsion device 25 is driven by a propulsion engine 25'a. In order to maintain normal operation without being affected by floating objects, protective nets 26 are attached to both sides of the propeller 25 to prevent floating objects from entering.

The operation of the rotary cutter 15.15a, the improved unloading conveyor 60, and the propulsion device 25 may be remotely controlled from the control platform 27 provided on the floating body 1 for convenience of navigation.

The front rotary cutter 15, the rear rotary cutter 158, and the improved unloading conveyor 60 may use the same driving source, or may be made independent of each other.

The collector B may be of any shape as long as it can store collected aquatic plants;
Considering the convenience of dehydration treatment and unloading of water hyacinth, which contains 5% water, a raised-bed twin-barrel type collector 30 will be described below as an example thereof.

As shown in FIG. 8, the raised-bed double-barrel collector 30 has a collection section 33 that is composed of a mesh-shaped floor 31 designed for drainage and a mesh-shaped wall 32 stretched above the periphery of the floor 31. It is equipped with

Although aquatic plants may be piled up directly in this collecting section 33, in order to more efficiently unload the aquatic plants from the collecting section 33, a net 34 is arranged inside this collecting section 33, and a net 34 is placed on top of it. Pile up aquatic plants.

Then, the aquatic plants are hoisted up together with the net 34 using a crane or the like, and then unloaded onto land or onto a transport medium such as a truck. The mesh type floor 31 is supported by floating bodies 35 placed on the left and right sides. Although the floating earth surface 36 may be used as a part of the mesh type floor 31, a support 37 is provided between the mesh type floor 31 and the floating body 35, and the mesh type floor 31 is connected to the floating body 35 via the support 37. If these are integrated, more effective drainage can be achieved.

The raised bed catamaran collector 30 is connected to the cutter vessel A by a connecting lobe 16 and towed.

The aquatic plants are continuously loaded and unloaded into the recovery section 33 by an improved unloading conveyor 60 provided on the cutter.

Since this invention is configured as described above, it can be used when aquatic plants float individually or in groups and are not in a state of natural reproduction. However, by taking advantage of its floating property, the aquatic plants can be properly cut, changed into a form that is easy to salvage, and then pulled up from the water surface and collected in the collection unit, rather than being pulled up from the water surface suddenly.

That is, while conventional vessels pull aquatic plants from the water surface immediately, the present collection vessel changes the aquatic plants into a form that is easier to collect before pulling them up. This is the reason why the collection rate of aquatic plants is dramatically higher than conventional ones, and the operation is efficient and inexpensive.

Furthermore, in the embodiment of the present invention, by arranging a rotary cutter in front of the recovery vessel, the recovery vessel can carry out efficient recovery operations even in areas where aquatic plants are abundant, and further,
By placing the rotary cutter 15 in front of the improved unloading conveyor 60, the drawbacks of the conventional belt conveyor system are effectively overcome.

The lower part of the rotary cutter 15 is submerged in water, and the blade 17 rotates backward in the submerged part and rotates forward on the water surface. Therefore, a water flow is generated by the rotation of the rotary cutter 15, and the aquatic plants that have been caught by the blade 17 are cut by the blade 17 and continuously transported rearward on this water flow.

The cut aquatic plants are removed from the hull 1 without staying in the bow area.
0, the recovery vessel can operate without being obstructed by aquatic plants, even in areas where aquatic plants are abundant.

If the rotary cutter 15 is placed in front of the improved unloading conveyor 60, the rotation of the blade 17 will force the aquatic plants to be transferred backwards between the blade 17 and the conveyor 60.
However, if the conveyor 60 is operated, the forcibly transferred aquatic plants are placed on the conveyor one by one.

As a result, it is possible to unload the aquatic plants more reliably and quickly than in the method of directly picking up aquatic plants using a conveyor.

Furthermore, the water flow generated by the rotary cutter 15 also acts as a propulsive force for the recovery ship.

Furthermore, since the blade 17 moves through the aquatic plants like a caterpillar by pulling in the aquatic plants and discharging them rearward, the blades 17 serve as motive force for the recovery boat.

〔Effect of the invention〕

As described above, the present invention has an integrated bow section consisting of a pair of left and right floating bodies provided with a passageway for collecting aquatic plants in the center, and is installed between the floating bodies, and is equipped with functions for mowing, cutting, and rearward feeding of aquatic plants. A rotary cutter is provided, and a collector is connected to the rear side of the hull to collect the aquatic plants fed by the rotary cutter, and the cut aquatic plants are sequentially placed in the passage for collecting aquatic plants in the vicinity of the rotary cutter. Since an unloading conveyor is provided to transport the cargo to the collector, the following excellent effects are achieved.

(2) In addition to mowing, cutting, and rear-feeding aquatic plants, the Coroly cutter also uses part of its power to propel the recovery vessel, so it works efficiently and without waste.

(2) Mowing, cutting, and rear-feeding utilize the buoyancy of aquatic plants, so they are always carried out on a flat surface, so no wasted energy is required for handling aquatic plants.

■The improved unloading conveyor picks up aquatic plants that have already been cut, so there is less chance of entanglement or snagging on the aquatic plants.

Furthermore, since the aquatic plants can be easily separated from each other, the collected aquatic plants can be easily handled. On the other hand, in the method of directly collecting flourishing aquatic plants, the aquatic plants tend to form clumps and are inconvenient to handle in post-processing.

■Unlike conventional vacuum-type aquatic weed collection vessels, it processes only aquatic weeds, so there is no power loss and the mechanism is simple.
Therefore, it is economical and easy to maintain.
