The base frame 820 may have a plate-shaped ship fixing plate 821 formed at one end thereof and the ship fixing plate 821 may stably fix the base frame 820 to the ship. At this time, the ship fixing plate 821 may be formed along the perimeter of the at least one coupling hole 822 for coupling with the ship, and the user may attach the base frame 820 to the ship for aquaculture, The base frame 820 can be coupled to the deck of the ship using bolts and nuts after the engagement holes 822 and the engagement holes formed on the deck for aquaculture are aligned.

The base frame 820 may be formed with at least one coupling hole (not shown) for coupling with the gear portion 810 and may be formed at a position corresponding to the coupling hole (not shown) One or more bonding holes (not shown) may be formed. At this time, a plating layer for preventing corrosion may be formed on the outer peripheral surface of the base frame 820.

The tongs 244 are cut by the cutter 225 to transport the seaweed accumulated on the deck. More specifically, the tongs 244 are for picking up the seaweeds and putting the abalone or the like into the caged cages. As a result, the aquaculture operators do not need to manually (manually) feed the seaweed from the ship to the cage, thereby significantly shortening the time required for supplying the seaweed, and the process of the operation can be greatly facilitated. At this time, the tongue 244 can be formed such that a part of the tip of the tongue blade 2441 overlaps with the tongue blade 2441 when the tongue blade 2441 is slid so that the slippery algae do not escape through the tongs.

The hook (243) is for lifting an abalone culturing hood or a culture net located in the sea. Raising an abalone cultivation hood is the most difficult task in abalone cultivation work. Conventionally, a plurality of workers have to gather their strengths before they can be loaded on a ship. The present invention can provide a great convenience to a user since the abacus can easily be lifted up by a hook 243 and loaded on a ship.

According to the embodiment of the present invention, the first cutter fixing portion 224 or the second cutter fixing portion 226 may be formed on one boom of the plurality of booms. Figure 3 shows a boom assembly 200 consisting of three booms and a first cutter securing portion 224 formed on the second boom 220. Figure 4 shows a boom assembly 200 comprising three booms, And a second cutter fixing portion 226 formed on the second boom 220. As shown in Fig.

The first cutter fixing portion 224 or the second cutter fixing portion 226 selectively coupled to the second boom 220 is a component for fixing the cutter 225 to the second boom 220.

The first cutter fixing portion 224 includes a U-shaped fixing ring 2241 coupled to a lower surface of the second boom 220 and an O-shaped first rope 2242 passing through the fixing ring 2241. [ . At this time, the cutter 225 is fixed to the first rope 2242, and more specifically, the first rope 2242 is inserted into the engaging member 2251 of the cutter 225.

The second cutter fixing portion 226 includes a rod-shaped fixing bar 2261 coupled to one area of the upper surface of the second boom 220 and a second rope 2262 fixed to both ends of the fixing bar 2261 do. At this time, the cutter 225 is fixed to the second rope 2262, and more specifically, the second rope 2262 is inserted into the engaging member 2251 of the cutter 225. At both ends of the fixing bar 2261, a separation preventing tab for preventing the second rope 2262 from being released may be formed extending vertically. In addition, a U-shaped fixing member 227 for fixing the fixing bar 2261 may be formed on one surface of the upper surface of the second boom 220.

The cutter 225 cuts seaweed bound to the rope. As a result, the shoe manufacturer does not have to cut the seaweed by using a cutting member such as a sickle or a knife directly (manually), so that a safety accident occurring in cutting the seaweed can be prevented.

5 shows a crane 1 of a marine aquaculture ship installed on a ship A according to an embodiment of the present invention.

A crane 1 is coupled to the ship of the marine culture ship A and a tongue 244 is coupled to one end of the crane 1. The user can pick up the seaweed B with the tongs 244 by inserting or withdrawing a plurality of booms and putting the abalone or the like into a caged cage.

The crane 1 may further include a crane operating unit 1000 according to an embodiment of the present invention. The crane operation unit 1000 is a component for adjusting the rotation of the post 100, the angle of the boom assembly 200, the pulling-in and pulling-out of the boom and the driving of the outer boom 240, A boom adjuster 1030, and an outer boom adjuster 1020. The boom adjuster 1030 and the boom adjuster 1030 are the same as those of the first embodiment.

The post plate and derrick cylinder adjuster 1010 are components that control the operation of the derrick cylinder 300 and a rotation module (not shown) that rotates the post plate 700. The user can adjust the rotation direction and the rotation angle of the crane 1 of the marine vessel for aquaculture by operating the post plate and derrick cylinder adjuster 1010 and adjust the angle of the boom assembly 200. [

The boom adjuster 1030 is a component that controls the operation of the boom cylinder 400. The user can simultaneously draw or pull out a plurality of booms by operating the boom adjuster 1030. [

The outer boom adjuster 1020 is a component that controls the operation of folding and unfolding the outer boom 240 and the operation of pinched and stretched pliers. The user can unfold the outer boom 240 in parallel with the boom assembly 200 by the operation of the outer boom adjuster 1020 or on the same line as the boom assembly 200. The end of the outer boom 240 The pliers 244 may be pivoted or pinched. At this time, the post plate and derrick cylinder adjuster 1010 and the outer boom adjuster 1020 may be formed as a joystick, and the boom adjuster 1030 may be formed as a foot lever. For example, when an upward pushing operation is input to the post plate and the derrick cylinder adjuster 1010 formed by the joystick, the angle of the boom can be raised. On the contrary, when the downward pushing operation is inputted, Can be lowered. When the pushing operation to the left side is inputted to the post plate and the derrick cylinder adjusting portion 1010, the post plate 700 can be rotated to the left side. On the contrary, when the right side pushing operation is inputted, Can be rotated to the right. By the rotation of the post plate 700, the post 100 coupled to the post plate 700 is also rotated.

When the upward pushing operation is inputted to the outer boom adjuster 1020 formed by the joystick, the forceps can be extended. On the contrary, when the downward pushing operation is inputted, the forceps can be pinched. When the pushing operation to the left of the outer boom adjuster 1020 is input, the outer boom 240 can be folded. On the contrary, when the pushing operation to the right is inputted, the outer boom 240 can be extended.

Since the boom cylinder 400 of the present invention has a plurality of booms drawn in and out at the same time according to the operation of the boom cylinder 400, it is possible not only to increase the efficiency of the work by shortening the intake and withdrawal time, do.

Further, since the boom cylinder 400 of the crane 1 of the present invention has a plurality of booms drawn in or pulled out, the weight of the boom can be reduced, and the boom cylinder 400 can be installed in a small ship.

It will be understood by those skilled in the art that the foregoing description of the present invention is for illustrative purposes only and that those of ordinary skill in the art can readily understand that various changes and modifications may be made without departing from the spirit or essential characteristics of the present invention. will be.
