Description

[Detailed description of the invention] This invention relates to an improvement of a seaweed picking device.

Recently, a part of the seaweed net that has been stretched out on the sea surface is lifted up and supported on board the seaweed, and the ship is moved under the seaweed net and along its length while hanging from the seaweed net. A seaweed-picking method has been developed in which seaweed is picked on board a ship by cutting the seaweed with a rotary automatic seaweed-picking machine.

However, with this method, the ship was moved by having workers manually pull the left and right edges of the seaweed net, so two workers were required and they had to lift the seaweed net, which had a large amount of seaweed attached to it. , it takes a lot of effort to track this on board.

In order to improve this, various methods and devices for automatically moving ships by passing under seaweed nets have been researched, but the devices are complicated and large and heavy, making it difficult to mount them on ships. It has not been put to practical use yet, as it is difficult to do so, and the seaweed net gets caught in the rotating claws.

This invention was made in view of the above-mentioned circumstances, and utilizes ropes connected along the longitudinal direction to the side edges of the seaweed net to stretch the seaweed net, and this rope is formed around the outer periphery of the rotating body. The ship is moved semi-automatically or automatically by fitting it into the groove, driving the rotating body, and pulling the rope through the frictional engagement between the rotating body and the rope, allowing one operator to move the ship. It is an object of the present invention to provide a seaweed picking device that is easy to use, reduces labor, and is suitable for practical use.

An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, 1 is a seaweed net, and ropes 2 are connected to both edges ζ of this net 1 along its longitudinal direction.
Both ends of the rope 2 are connected to piles driven into the seabed or dropped anchors (not shown), and a seaweed net 1 is stretched on the sea surface. Float cylinders 3 made of bamboo or the like are installed at intervals of about 1.8 to 3.6 m.

Reference numeral 4 denotes a small boat, and this boat 4 is equipped with a conventionally known automatic laver picking machine 5 of a rotary type for cutting and picking the laver hanging down from the seaweed net 1.

6 is a rope pulling machine incorporated in the seaweed picking machine 5,
It is structured as follows.

That is, the rope pulling machine 6 includes a rotating body 8 that is driven by an engine 7 mounted on the boat 4 in conjunction with the seaweed picking machine 5 and via a speed reducer 7a.

As shown in FIGS. 1 to 4, this rotating body 8 has a groove 9 formed on its outer periphery, and a large number of convexities 10 radially formed in the shape of an umbrella gear on the opposite side surface of the groove 9. Is that the ■groove? A rope entanglement prevention claw 11 having a substantially semi-circular arc shape is loosely fitted into the upper center side of the rope, and a protrusion provided at one end of this claw is pivotally supported on the machine base 12 side so as to be rotatable on a vertical plane. There is.

As shown in FIGS. 1 and 2, a feeding drum 13 for the float cylinder 3 is provided coaxially and integrally with the rotating body 8 on the outer surface of the rotating body 8, and the outer periphery of the feeding drum 13 to 3
The protruding pawls 14 are formed at equal angular intervals.

A rope return tram 15 is provided coaxially and integrally with the rotor 8 on the inner surface of the rotor 8.
A spiral groove 16 is formed on the outer periphery of the rotor 5, and the outer diameter of the bottom surface of the groove 16 is equal to or larger than the outer diameter of the rotating body 8.

A guide drum 17 is installed in front of the rotating body 8, and a rope return front drum 1 having a spiral groove 18 on the inner surface of the drum 17 is similar to the rope return drum 15.

The rotating body 8 and the guide drum 17 are connected to the bracket 2
0.21, each of these bladders "7"
0 and 21 are fixed to the machine base 12.

Further, the rotating body and the guide drum 17 are connected from the output shaft of the reducer 7a to the output shaft IJ30, 31 and the endless belt 22.
, 32 and pulleys 33, 34 so that the driving force is transmitted and driven.

However, as shown in FIG. 2, the driving force of the rotating body 8 is transmitted by a tension pulley 23 disposed above the endless belt 22 that presses against the endless belt 22 from above.

That is, the tension pulley 23 connects the intermediate portion to the pin 24.
An arm 24 rotatably supported on the machine base 12 by a
A wire 25a is pivotally supported at the upper end and connected to the clutch pedal 25 when the clutch pedal 25 is depressed.
By rotating the arm 24 clockwise through the arm 24, the arm 24 is brought into pressure contact with the endless belt 22 and transmits the driving force to the rotating body 8.

Further, by releasing the clutch pedal 25, the arm 24 is rotated counterclockwise about the pin 24a by the spring 29 stretched between the lower end of the arm 24 and the spring adjustment screw 28, and the tension pulley 23 is rotated endlessly. It is separated from the belt 22 and transmission of driving force to the rotating body 8 is cut off.

A weight roller 26 is installed behind the rotating body 8, and an arm 27 that pivotally supports this rope 26 is pivotally supported on the bracket 20 of the rotating body 8 or a bearing provided thereon so as to be rotatable in a vertical plane. .

In this embodiment, a guide drum 17, a rotating body 8, and a weight roller 26 are arranged on one side of the ship 4, and an engine 7 is arranged on the other side.

To pick seaweed using the seaweed picking device configured as described above, one end of the seaweed net 1 is lifted and placed on the automatic seaweed picking machine 5, and the rope 2 is inserted into the groove 9 of the rotating body 8. It is fitted and supported on the guide drum 17, and further supported by weight rollers 26 from above.

In this state, the engine 7 is driven to operate the seaweed trimming machine 5, and the rotating body 8 and the guide drum 17 are rotated clockwise in FIG. 2 via the reducer 7a. By frictionally engaging the opposing side surface with the rope 2 and pulling the rope 2, the ship 4 is moved to the second
Move from the right side of the diagram to the left side.

Along with this movement, the operator can move the ship 4 along the longitudinal direction of the seaweed net 1 while maintaining its straightness by pulling the rope 2 or the seaweed net 1 with the engine 7 side part of the ship 4 as necessary. At the same time, the seaweed net 1 is removed by the seaweed picking machine 5.
The seaweed that hangs down from the seaweed is cut and picked.

In this case, the unevenness 10 is formed on the opposite side surface of the groove 9 of the rotating body 8, and the weight roller 26 presses the rope 2 to increase the contact length between the rotating body 8 and the rope 2. 2 can be prevented from slipping, and the ship 4 can be moved reliably.

In addition, since the rope return drum 15 and the rope return front drum 19 are provided on the rotating body 8 and the guide drum 17, the spout 2 is connected to the rotating body 8 by these spiral grooves 16 and 18.
Even if the rope 2 comes off the ■groove 9, it can be returned to the ■groove 9.

Further, since the feeding tram 13 is provided integrally with the rotating body 8, the rotation of the tram 13 allows the float cylinder 3 to be fed by its protruding pawls 14 without having to be removed.

In the present invention, in the embodiments described above, a foot-operated tension clutch was provided to ensure safety and adjust the moving speed of the boat, but any suitable clutch may be used instead.

Further, the rope return drum and the rope return front drum may be provided on both sides of the rotating body and the guide drum, if necessary.

Furthermore, since the uneven seaweed formed on the opposite side surface of the groove of the rotating body adheres, it is preferable to provide means for removing it, and this means may be attached to the rope entrapment prevention claw 11.

In the above embodiment, only the rope on one side of the seaweed net is pulled by the rotating body, but a pair of left and right rope pulling machines may be provided so that the ropes on both sides are pulled by the rotating body.

As explained above, according to the seaweed picking device according to the present invention, the rope for setting up the seaweed net is brought into frictional engagement with the rotating body and the rope is pulled to move the ship, so at least While the ship can be moved semi-automatically, it can be moved by a single worker, reducing labor.Moreover, the device has a relatively simple configuration, can be made lighter and smaller, and has fewer failures, making it practical. It is possible to provide a seaweed picking device suitable for
