Description

Technical Field

[0001] The present invention relates to the technical field of oyster raft culture, and in particular to a longline oyster mechanized seeding machine and its use method. Background Art

[0002] The oyster farming and development industries are spread all over the world and are highly regarded by coastal countries around the world because of their short food chain, fast growth, high yield, and good economic benefits. Among the countries producing oysters globally, China has the highest oyster production. Moreover, with the development of China's economy and the increasing living standards of the people, the demand for oyster products is also growing rapidly. By 2020, China's oyster production has accounted for more than 85% of the global total, and it has shown a rapid and substantial increase since the 21st century. However, in sharp contrast to the large-scale and intensive oyster farming model, the problem of the increasingly scarce agricultural labor force and the lack of labor is becoming increasingly apparent, which has affected the further development of the oyster farming industry. Oyster farming in China mainly adopts the longline raft frame technology, which belongs to heavy physical labor. The longline hanging culture mainly suspends the oyster seedling attachment bases in series through ropes under the buoyant longline to form a raft frame for cultivation. The processes of clamping seedlings, harvesting, cleaning, and shelling of longline oysters are several of the most important links in the oyster farming production process, and a large amount of work is completed by manual labor, belonging to a labor-intensive operation mode. Especially in the manual clamping of oyster seedlings, the short-term demand for labor is large, it is difficult to recruit workers, and the manual efficiency is low and the instability is high. At present, the attachment bases used in longline oyster farming are mostly scallop shells or oyster shells. Generally, a small hole is drilled in the scallop shell or oyster shell in the nursery. Farmers use rubber threads to tie the attachment base to the culture rope through this small hole. However, as the attachment bases of scallop shells or oyster shells are usually of different sizes and irregular shapes, the size and position of the holes drilled on the attachment bases are not fixed. And in order to prevent the grown oysters from loosening and shifting, the rubber threads need to be inserted back and forth in the gaps of the culture rope, which greatly increases the mechanization difficulty of oyster seeding. At present, the mechanization degree of the seeding link is the lowest, and it completely depends on workers to manually insert the oyster seedling attachment base into the rubber thread and then tie it to the culture rope. The whole process is time-consuming and laborious, with low production efficiency, and the attachment bases are unevenly distributed on the seedling rope, affecting the growth rate of oysters. The lack of supporting mechanized equipment has obviously become the main bottleneck restricting the development of oyster farming, and the industry urgently needs supporting equipment that can replace manual labor to achieve mechanized and automated operations for oyster clamping.

[0003] Therefore, in order to improve the efficiency and quality of oyster clamping, promote the healthy development of the oyster farming industry, and boost the transformation of the fishery production mode, it is necessary to carry out research on the key technologies and related equipment for clamping seedlings that are compatible with the existing oyster farming rafts, and strive to achieve mechanization in the oyster farming link as soon as possible.

[0018] A method for using the longline oyster mechanized seedling threading machine according to the present invention includes the steps:

[0020] S2: Start the conveying and separation mechanism and the turnover mechanism, the horizontal cylinder extends outward, and the vertical cylinder retracts inward. At this time, the negative pressure suction cup descends to the outlet of the seedling string storage box to absorb a single oyster seedling attachment base; then the vertical cylinder extends outward to separate the single oyster seedling attachment base from the oyster seedling string. At the same time, the turnover mechanism and the vertical screw slide act synchronously, and the turnover claw rotates to the bottom of the negative pressure suction cup, and the seedling string top extension paddle conveys the oyster seedling string upward to the outlet of the seedling string storage box; then the negative pressure suction cup releases the single oyster seedling attachment base, the horizontal cylinder retracts inward, and the negative pressure suction cup returns to the initial position, and this action process is continued in a cycle to realize the conveying and separation of the single oyster seedling attachment base and the oyster seedling string;

[0022] S4: After the fixing mechanism completes one cycle of action, the seedling rope clamping cylinder closes and clamps the finished seedling rope. At the same time, the limit motor of the seedling rope limiting component is started, and the seedling rope conveying cylinder retracts, driving the closed seedling rope clamping cylinder to convey the finished seedling rope backward at a fixed distance. Then the seedling rope clamping cylinder opens to release the seedling rope, the limit motor of the seedling rope limiting component is closed, and the finished seedling rope conveying cylinder extends outward and returns to the initial position. At this time, the seedling rope conveying and storage mechanism completes one action cycle, and the finished seedling rope is conveyed to the seedling rope storage basket under the guidance of the seedling rope output pallet.

[0023] The present invention adopts the above technical solution, so it has the following beneficial effects:

[0024] 1. In the present invention, the conveying and separating mechanism innovatively adopts the operating principle of negative pressure adsorption. By using a negative pressure suction cup and cooperating with a lead screw slide table, a disc-type turnover mechanism, etc., it can effectively achieve the separation and directional conveying of oyster attachment base monomers and seedling strings. The bottom of the negative pressure suction cup is made of flexible material, which causes no damage to oyster seedlings and can effectively adsorb different attachment bases such as oyster shells and scallop shells.

[0025] 2. In the present invention, the fixing mechanism innovatively uses the method of tying with cable ties to realize the tying and fixing of oyster seedling attachment bases, glue filaments and seedling ropes. The fixing reliability is high. Cooperating with the seedling rope conveying and storage mechanism, the attachment bases are neatly arranged after fixing.

[0026] 3. The long-line oyster mechanized seedling threading machine of the present invention occupies a small space and is convenient to move. Compared with manual seedling threading, it does not require complex operating actions such as perforating, twisting ropes, and threading ropes. Workers only need to perform simple auxiliary operations, which can reduce the labor intensity of workers and improve production efficiency.

[0027] 4.
