Description

[Detailed explanation of the idea] The present invention relates to a device for extracting seaweed net struts.

As is well known, the nori net posts planted in seaweed fishing areas are bamboo posts with punched out knots to eliminate their own buoyancy, and after cutting off the bottom end at an acute angle, a rope is wrapped around it to prevent it from being pulled out. They are fixed and buried in the seabed, or they are driven into the ground and planted from above, and used for seaweed cultivation.

In order to remove this seaweed after the end of the seaweed season, conventional methods have been used: A worker on board the ship manually pulls the top of the pillar and pulls it out onto the ship.

(b) If the fishing ground is shallow, use water pressure to dig out the base of the bamboo support in the same way as in (a), and then a worker can go directly into the sea and pull out the support.

(c) A ratchet-type winch that operates by hand is installed on the ship, and the bamboo support is held in place with special metal fittings, and the winch is gradually wound up by hand to remove the support.

This is done by means such as.

However, in the cases (a) and (b) above, digging out the roots using a pressure pump was difficult, and even after digging out the roots, manual labor was required to pull them out one by one.

Moreover, in the case of (c) above, the hoisting speed is slow and work efficiency is lacking.

Therefore, (d) if the winch is operated using a DC motor instead of the manual winding operation, a large battery with a large capacity will be required to satisfy the work throughout the day.
In addition, the necessity of recharging the battery over and over again is recognized,
Furthermore, the use of a generator is expensive, making it difficult to reduce the cost of the entire device.

In view of the above-mentioned points, the present invention aims to use a small and lightweight engine to easily and quickly extract the seaweed net struts from a ship, and to save labor.

Note that 1a is a guide edge at the front end of the base plate 1.

Next, to explain the operating state of the device of the present invention, first, the engine E is driven, and when the operating lever 15 is pulled forward and tilted to the position F, the movable plate 9 fixedly supported at the bottom of the engine E moves to its guide frame 11. , the sphere 19 on the side of the engine mount 4a slides rearward along the guide elongated hole 22 of the engine mount 4a, and is forcefully engaged with the through hole 21a from either of the through holes 2L21b.

At the same time, the belt 26 suspended between the driving pulley 23 and the driven pulley 25 is tensed as shown in FIG. Rotate the drum 6.

At this time, the winding drum 6 rotates forward in the direction of winding up the chain 7 fixed to the drum 6.

In this state, push the operating lever 15 slightly forward from the front (N)
When the movable plate 9 fixedly supported on the bottom of the engine E is returned to the position shown in FIG. It slides slightly forward along the guide slot 22, and the sphere 19 on the engine mounting base 4a side moves into the through hole 2.
1a and is biased into engagement with the through hole 21.

At the same time, the belt 26 suspended between the drive pulley 23 and the driven pulley 25 is relaxed as shown in FIG.

Therefore, the winding drum 6 remains stationary.

From this state, when the operating lever 15 is further pushed forward and tilted to the R position, the movable plate 9 reaches the front end position, and the forward motion hip sphere 19 disengages from the through hole 21 and attaches to the through hole 21b. forces engage.

At the same time, the suspended belt 26 is further loosened, while the outer peripheral surface of the disc-shaped 24 that is pivotally attached to the output shaft 23a of the engine E is fixed to the input shaft 5b of the reducer 5, as shown in FIG. 5C. Alternatively, it presses into engagement with the outer circumferential surface of the ring body 27a fitted onto the outer circumferential surface.

As a result, the driven disk type 27 or ring body 27a on the reducer 5 side rotates the rotary waist winding drum 6 in the opposite direction to the driving disk type 24.

Therefore, the chain 7 wound around the winding drum 6 is made to act in the spring direction.

In order to use the proposed device having such a configuration and function in a seaweed fishing ground, first, the proposed device is mounted on a small boat S equipped with an outboard motor, and the boat is operated to the seaweed fishing ground, and then the device is placed on the stern or bow side of the boat. By extending the front end of the base plate 1 of the proposed device and stringing a rope to the rear half of the plywood, the proposed device can be attached to the ship.
Stable support and fixation on top.

Next, while driving the engine E, holding the hook 8 at the end of the chain 7 wound around the winding drum 6 in one hand, the chain 7 was wrapped once around the head of the seaweed net support 29 exposed on the sea. When the chain 77 is inserted into the appropriate position through the notch 8a of the hook 8, the chain 7 is released, and the operating lever 15 is pushed to the R position, the driving disc bundle 24 and the driven disc bundle 27 or their rings 27a are separated. As shown in FIG.
rotates in the opposite direction, and the lower end of the chain 7 sinks into the sea along the support 29.

After winding down the chain 7 in this way, next turn the operating lever 15.
When the belt 26 is pulled to the position F, that is, to the front, the belt 26 suspended between the driving pulley 23 and the driven pulley 25 becomes tensioned as shown in FIG. Wind up the drum 6 chain 7.

During this winding, the lower end of the chain 7 tightens the support column 29 without breaking it, and by further operating the hoist, the support column 29 is pulled out from the seabed.

When the head of the support column 29 is pulled and loaded onto the ship S, and the operating lever 15 is returned to the N position at the same time, the drive pulley 23 and the drive disc bundle 24 idle together as shown in FIG. 5, and the chain 7 is hoisted. Haruyoshi stops.

Thereafter, the chain 7 wound around the support 29 is removed from the notch 8a of the hook 8, and the above operation is repeated again to remove the seaweed net support 29 from the seaweed fishing ground.

As mentioned above, when removing the support 29, specifically, operating the operating lever 15 back and forth, winding the chain 7 around the head of the support 29, loading the support 29, etc., the operator must Usually, one foot is placed on the footrest 4b of the base 4 to perform each of the above operations.

Since the present invention is configured as described above, by using a small and lightweight engine, it is possible to easily and quickly extract the seaweed net struts from a ship, and to save labor in this work.

Furthermore, since the entire device is compactly constructed, it brings about various effects such as being able to be provided to the market at a low price.
