[0002] China is the world's largest laver farmer; currently, farmed laver is harvested primarily through manual and semi-mechanized methods, which are labor-intensive and inefficient. Traditional harvesting equipment involves foam raft tugboats, which are constructed from foam plastics and assembled into a hull. Due to the low cost of the raw materials and the ease of hull construction, these vessels are often home-made by farmers, often lacking in safety features such as high flammability, low wind resistance, and low strength. Furthermore, the curtain-lifting devices on foam raft tugboats are often fixed, extending from the front of the hull, which can easily cause maritime accidents during navigation. Therefore, a method or device that can address these issues is needed. Summary of the Invention

At the same time, the two ends of the adjusting rod 12 are also respectively connected to a set of adjusting mechanisms.

[0016] The adjusting mechanism includes a first rocker arm 13 whose bottom end is hinged to the bottom of the supporting frame body 6, the top end of the first rocker arm 13 is rotatably connected to the bottom end of the second rocker arm 14, and the top end of the second rocker arm 14 is hinged to the bottom end of the L-shaped rocking member 15, the L-shaped rocking member 15 is rotatably supported on the supporting frame body 6 through a rotating shaft, and the top end of the L-shaped rocking member 15 is hinged to the bottom end of the third rocker arm 16, and the top end of the third rocker arm 16 is rotatably connected to the end of the adjusting rod 12 through a connecting shaft, a driving cylinder support plate 17 is provided in the middle of the supporting frame body 6, the bottom end surface of the driving cylinder support plate 17 is hinged to the driving cylinder 18, and the working end of the driving cylinder 18 is hinged to the middle of the first rocker arm 13.

[0017] A pair of rails 19 are provided on the guide bracket 2, and a roller 20 matching the rails 19 is provided at the tail end of the curtain-lifting part 3, that is, the roller 20 is rollingly connected in the rails 19, and a limiting frame 21 is provided at the front end of the guide bracket 2, and a limiting opening 22 matching the front end of the curtain-lifting part 3 is provided at the top of the limiting frame 21. At the same time, an auxiliary bracket 23 is also provided at the bottom end of the curtain-lifting part 3, and the auxiliary bracket 23 matches the limiting frame 21. At the same time, a plurality of pairs of equally distributed transverse limiting brackets 24 are provided on the guide bracket 2, and the transverse limiting bracket 24 is in the shape of an isosceles triangle.

[0018] The precise laver cutting device of the embodiment of the present invention works as follows: When laver is cultivated in a factory, multiple parallel and equidistant nets are generally set up in the cultivation area. The cultivation area is formed between adjacent nets. In the cultivation area, a seedling cultivation curtain is set up (the seedling cultivation curtain is connected to the nets on both sides). Under the seedling curtain, multiple seedling ropes are connected, and the laver grows on the seedling ropes.

[0019] When it is necessary to mow the laver, first lower the curtain part 3 and let the front end of the curtain part 3 sink below the water surface. At this time, the auxiliary bracket 23 on the bottom end surface of the curtain part 3 is placed on the limit bracket 21, and the curtain part 3 and the guide bracket 2 together form an upward inclined guide structure; then let the hull 1 in the device sail to one end of a certain breeding area, and then let the hull 1 sail at a constant speed from one end of the breeding area to the other end. In this process, since the seedling curtain is fixed relative to the net, and the hull 1 moves relative to the net, the curtain part 3 located in the underwater part will guide the seedling curtain above it during navigation, and further move it to the mowing mechanism 5. The mowing mechanism 5 cuts the naturally hanging laver, and the cut laver leaves fall directly into the cabin 4, while the laver roots move toward the rear of the hull 1 along the seedling rope until they pass the end of the guide bracket 2 and fall back into the water.

[0020] That is, when the boat hull moves from one end to the other in a certain aquaculture area, the cutting mechanism 5 thereon will automatically cut off all the laver in the aquaculture area. In the above process, since a plurality of pairs of transverse limiting brackets 24 are provided on the top of the guide bracket 2, these pairs of transverse limiting brackets 24 can confine the laver above the boat hull 1 during its movement relative to the boat hull 1, thereby ensuring the effective cutting of the laver.

[0021] After the cabin 4 is filled with laver, the laver is transferred out of the cabin 4 and properly processed and stored, and then the hull 1 continues to sail in the designated breeding area until all the laver that needs to be harvested is cut down;

[0022] After the harvesting is completed, the staff pulls the curtain part 3 backward. At this time, the roller 20 rolls in the track 19, and the curtain part 3 moves as a whole to the rear of the guide bracket 2. After the movement is in place, the front end of the curtain part 3 is inserted into the limiting opening 22 on the limiting bracket 21. Under the action of the limiting bracket 21, the curtain part 3 is retracted on the guide bracket 2, and the hull 1 can sail normally.

[0023] The working process of the mowing mechanism 5 is as follows: the motor 10 drives the shaft 7 to rotate at a constant speed through the pulley transmission pair 9.

[0024] When the adjustment rod 12 needs to move, the control system controls the two drive cylinders 18 to move simultaneously. The drive cylinder 18 drives the first swing rod 13 to swing, the first swing rod 13 drives the second swing rod 14 to swing, the second swing rod 14 drives the L-shaped swing member 15 to swing, and the L-shaped swing member 15 drives the third swing rod 16 to move. When the two third swing rods 16 move synchronously, they drive the adjustment rod 12 to move relative to the protective net cover 11. Because the two ends of the adjustment rod 12 are slidably connected to the arc-shaped grooves provided on the protective net cover 11, when the adjustment mechanism drives the adjustment rod 12 to move, the adjustment rod 12 moves in space along the trajectory of the arc-shaped grooves.

[0025] When the laver moves to the mowing knife 8, the naturally hanging laver will come into contact with the rotating mowing knife 8, and the mowing knife 8 can cut the laver from the seedling rope. During the cutting process, the part below the adjusting rod 12 can come into contact with the mowing knife 8 and be cut, while the part above the adjusting rod 12 cannot come into contact with the mowing knife 8, that is, the part above the adjusting rod 12 is the root system retained during the laver harvesting process; that is, during the harvesting process, by adjusting the relative position of the adjusting rod 12 on the protective net cover 11, the length of the root system that needs to be retained can be adjusted.
