Field of the Invention The present invention relates to a structure of a transfer device for collecting and transferring an object to be transferred in an aquatic plant collecting work ship for collecting aquatic plants such as algae, aquatic plants and seaweeds. It is a thing.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Utility Model Laid-Open No. 60-19492.
As disclosed in Japanese Patent Laid-Open No. 3 and the like, a recovery unit (lifting unit) of a bow of an aquatic plant collecting work ship is provided with a reaping mechanism in an opening front end frame having a rectangular shape in front view, and from the opening front end frame to a base portion. An aquatic plant collector with a reticulated endless conveyor belt at the bottom is provided to be movable up and down, and the first conveyor is composed of a number of belt-shaped conveyor belts from the base of the aquatic plant collector toward the stern (rear end) of the work boat. Proposed is one in which a conveyor and a second conveyor are provided in series, and the end of the second conveyor, which projects rearward from the rear end of this work boat, is arranged so as to be above the deck of the work boat. Has been done.

[0003]

By the way, in this type of aquatic plant collecting work ship, a recovery ship (accommodation ship) is towed to the stern (rear end) side of the recovery work ship from the end of the second transfer conveyor. Items to be transported of aquatic plants such as algae are dropped and stored on a (storage vessel), but if the aquatic plants are rolled into a columnar shape (roll shape) in a side view before that, the volume becomes low and they are collected. You can increase the weight of aquatic plants that can be stored in the ship.

However, the above-mentioned prior art aquatic plant collecting work boat was not provided with a mechanism therefor.
A first object of the present invention is to make it possible to bend an intermediate part of a conveyer conveyor at a substantially right angle so that an object to be conveyed such as an aquatic plant can be formed into a roll shape. In addition, in order to enable the height position of the end of the second conveyor to be increased in the aquatic plant collecting work vessel of the above-mentioned prior art and to enable the conveyance of a roll-shaped object to be conveyed, the inclination of the second conveyor should be inclined. You have to make the angle smaller, and then
The length of the second conveyor is increased. If the second conveyor is configured to stand upright in order to form the conveyed object in a roll shape, the length of the second conveyor is long, so that the second conveyor in the standing state is blown by the wind. When hit, there was a problem that the stability of the work boat deteriorates.

A second object of the present invention is to simplify the structure of the entire conveying device so as to form an object to be conveyed such as an aquatic plant in a roll shape, but at the height position of the end of the conveying conveyor. It is an object of the present invention to provide a transfer device that can be made large.

[0008]

EXAMPLE Next, an example in which the present invention is embodied will be described. FIG. 1 is a side view of an aquatic plant collecting work boat 1 for cutting and collecting aquatic plants such as algae, seaweeds, and aquatic plants. There is an unshown aquatic plant collecting work boat 1 with an engine, and the storage boat 2 having an open upper surface is towed to the stern (rear end) thereof.

Although not shown in detail, a bow (front end) of the aquatic plant collecting work boat 1 is provided with an aquatic plant collecting machine 4 composed of a frame body 6 and the like which can be rotated up and down about a pivot 3.
The aquatic plant collector 4 is configured to be movable up and down between a state below the water surface and a state above the water surface by an actuator such as a hydraulic cylinder (not shown). This aquatic plant collector 4
Is a clipper type reaping mechanism (not shown) on at least the lower side portion and the left and right side portions of the opening front end frame 5 which is rectangular in a front view.
And a wire mesh endless conveyor belt is arranged at the bottom from the opening front end frame 5 toward the base.

An endless belt body such as a wire mesh endless belt, a belt endless belt or a woven endless belt is provided on the deck (not shown) of the aquatic plant collecting work boat 1 connected to the base end of the aquatic plant collecting machine 4. 8 is a drive pulley 9 at the front end and a driven pulley 10 at the rear end.
A conveyer conveyor 7 wound around and is arranged. A bridge 11 is installed in the middle of the front and rear of the aquatic plant collection work boat 1 so as to straddle above the conveyor 7 for transportation. The bridge 11 is provided with a driver's seat 12 and a steering wheel 13. The operation unit 14 is provided, and the entire upper surface of the aquatic plant collection work boat 1 can be seen, and the forward / backward / stop of the aquatic plant collection work boat 1, the operation such as the up / down movement of the aquatic plant collection machine 4, and the operation of the conveyor 7 for transportation. It is configured to execute and monitor operating conditions.

[0011] In the middle of the front and rear of the conveyor 7 for carrying,
At least one intermediate roller body 15 for supporting the upper conveying surface of the endless belt body 8 is arranged,
Intermediate roller body 1 at a position behind the bridge 11
In order to enable the rear side of the endless belt body 8 to bend upward and rise about the location of 5, the intermediate roller body 15 and the driven pulley 10 at the rear end are connected by a pair of left and right frames 16, and hydraulic pressure is applied. One end of the elevating means 17 such as a cylinder is connected to the hull and the other end is connected to the frame 16.

FIGS. 2 and 3 are for preventing the upper side of the endless belt body 8 (conveying side of the conveyed object) from floating up from the position of the intermediate roller body 15 when the rear side of the endless belt body 8 is bent upward. An example of the regulating means 18 is shown, and a pair of front and rear pedestals 19 and 2 are provided on both left and right sides of the intermediate roller body 15.
0 is erected, and motors 21 capable of rotating in the forward and reverse directions are fixed to the bases 19 on the left and right sides, respectively, and the tip end of a screw shaft 22 rotating by the motors 21 is rotated by a bearing 23 fixed to each base 20. Only freely support the shaft. Then, a vertically inverted L-shaped bracket 25 is erected on a nut member 24 screwed to each screw shaft 22, and the pressing roller 2 is laterally attached to the tip of each bracket 25.
6 is rotatably supported. Each presser roller 2
The lower end of the outer periphery of 6 can contact the upper side surface of the endless belt body 8 (conveying surface of the conveyed object), and the motor 21
2, the arrangement position of the pressing roller 26 on the upper side of the intermediate roller body 15 is adjustable back and forth.

Therefore, by arranging the left and right pressing rollers 26 at the rear side of the center of the intermediate roller body 15, the length of the rear side of the endless belt body 8 can be shortened, and the rear side of the endless belt body 8 is substantially upright. It is possible to shorten the standing height when standing up in a shape. On the other hand, if the left and right presser rollers 26 are arranged in the portion closer to the front than the center of the intermediate roller body 15, the length of the rear side of the endless belt body 8 can be increased, so that the rear side of the endless belt body 8 becomes a horizontal plane. To the angle θ
When the inclination is arranged (less than 90 degrees), the height position (H) of the conveyance end of the endless belt body 8 can be increased even if the inclination angle is gentle.

With the above structure, the drive pulley 9 is operated while the rear side of the endless belt body 8 is erected substantially upright (see the chain double-dashed line in FIG. 1), and the upper side of the endless belt body 8 is hulled. When the aquatic plants collected by the aquatic plant collector 4 are transferred to the rear part, the aquatic plants cut from below the water surface are transferred to the stern side by the conveyor 7 for transportation.
When the aquatic plant is rolled into a roll shape at the bent portion of 6 and the roll-shaped transported object 27 has a certain diameter,
By operating the elevating means 17, the rear side of the endless belt body 8 is held in an inclined posture so that the rear side of the endless belt body 8 becomes an angle of less than 90 degrees with respect to the horizontal (see the solid line state in FIG. 1), and the transported object 27 is endlessly conveyed. It may be transferred to the end side of the belt body 8 and dropped on the container ship 2 for storage. If the length of the pressing roller 26 in the restricting means 18 in the above-described embodiment is made shorter than the width dimension of the endless belt body 8, it will interfere with the transported object 27 transferred on the endless belt body 8. Less is. In that case, it is more effective to reduce the diameter of the pressing roller 26.

Restricting means 18 in the embodiment shown in FIG.
Is a pair of left and right arms 29 (one of which is not shown) having a pivot 28 on the lower side of the conveyer 7, and a pressing roller 30 having a length substantially equal to the width dimension of the endless belt body 8 is rotatably provided. It is formed in a gate shape, and both arms 29 are configured to be vertically rotatable by an actuator 31 such as a hydraulic cylinder, and both arms 29 are held in a laid down state. If the upper surface is pressed in the vicinity of the intermediate roller body 15, the endless belt body 8 does not float up at the bent portion when the rear side of the endless belt body 8 is made upright or rearwardly inclined. Further, by adjusting the fall angle of both arms 29, it is also possible to moderate the inclination angle by slightly sacrificing the rising of the bent portion when the rear high inclination shape is adopted. Since the endless belt body 8 is continuous at the bent portion of the endless belt body 8 by the regulating means 18, the aquatic plant does not fall out of the belt body. Further, if the diameter of the presser roller 30 is reduced,
It is less likely to interfere with the transported object 27 transferred on the endless belt body 8.

In the embodiment shown in FIG. 5, the rear end of the bridge 11 is located in front of the driven pulley 33 at the rear end of the first transfer conveyor 32 having the same structure as that described above and arranged on the deck of the work boat 1. The regulating means 1 having the same structure as that of the above-described embodiment, which includes the intermediate roller body 15 at a rear portion or in the middle of the bridge 11 and the like, and the pressing roller 26 or 30 near the upper portion thereof.
8, the second conveyor 34 is arranged in series at the rear end of the first conveyor 32, and the drive pulley 36 on the front end side around which the endless belt body 35 having the same structure as the above is wound. Set the driven pulley 37 on the rear end side to the pair of left and right frames 3
8, and an elevating means 39 such as a hydraulic cylinder is mounted between the frame 38 and the hull.

The driven pulley 33 at the rear end of the first transfer conveyor 32 and the frame 38 near the drive pulley 36 at the front end of the second transfer conveyor 34 are connected together.
It is removably connected at 0 (reference numeral 41 is a mounting bolt). The connecting body 40 is configured so that it can be attached to the frame 38 near the drive pulley 36 and the hull (deck, not shown).

According to this structure, the endless belt member 8 of the first conveyor 32 can be kept substantially horizontal while the connecting member 40 is connected to the frame 38 and the ship (deck). When the elevating means 39 such as a hydraulic cylinder is actuated to raise the frame 38, the second conveyer conveyor 34 stands up substantially vertically around the drive pulley 3 side at the front end. The aquatic plant transported by the endless belt body 8 can be made into the roll-shaped transported object 27 by the action of the endless belt body 35 which is transferred and rotated in the upward direction.

In this case, if the height (length) of the second conveyor 34 is shortened, the influence of the wind hitting the standing second conveyor 34 can be reduced and the stability of the work boat is reduced. There is nothing to do. On the other hand, the driven pulley 33 at the rear end of the first conveyor 32 and the second conveyor 3
When the rear end side of the second conveyer conveyor 34 is raised by the operation of the elevating means 39 in a state where the frame 38 near the drive pulley 36 at the front end of 4 is connected by the connecting body 40, the first conveyer conveyor. The pressing roller 26 is bent in the vicinity of the intermediate roller body 15 in the middle of the front and rear of 32, and the upper surfaces (conveying surfaces) of the endless belt bodies 8 and 38 can be held in a straight line behind the bending position. (See the double-dashed line in FIG. 5), it has the same effect as increasing the transport length in the inclined portion, and the second angle is reduced in the state where the inclination angle θ is reduced.
Therefore, the height position of the rear end of the conveyor 34 can be increased. When the aquatic plant collecting work is not performed, the first conveyor 32 and the second conveyor 34 can be arranged horizontally on the deck, and the stability of the work boat is improved.
