Detailed Description
As shown in figures 1 to 3, the clam seedling collecting and catching device comprises a frame body 1, a scraping plate 2 and a collecting net 3, wherein the frame body 1 is a triangular frame, and during collecting and catching, the triangular frame can reduce resistance, so that the collecting and catching device is kept stable at the water bottom. The bottom edge 4 of the frame body 1 is connected with one side of the scraper 2, the top angle of the frame body 1 is connected with the harvesting ship, specifically, the angle, opposite to the bottom edge 4, on the frame body 1 is the top angle, the top angle is connected with the harvesting ship through a steel wire rope, when harvesting, the harvesting ship sails in a sea area, and the harvesting ship drags the harvesting ship to move at the bottom through the steel wire rope, so that the harvesting and catching are realized. Still be equipped with dead lever 5 on the support body 1, dead lever 5 and base 4 parallel arrangement, the one side that is close to support body 1 on the scraper blade 2 is equipped with a plurality of connecting holes 7, collect the one side of net 3 open end and pass through connecting hole 7 and be connected with scraper blade 2, the opposite side of collecting the net 3 open end passes through dead lever 5 and is connected with support body 1, when adopting and catching, the seed and the silt that 2 scrapes of scraper blade get into along scraper blade 2 upward movement and collect in net 3, along with adopting the removal of catching the ware in the sea water, the sea water washes the seed of collecting in net 3, collects net 3 along with the sea water discharge with silt and other microorganism, avoids adopting other microorganisms in the sea area in the lump, avoids adopting and catches the ecological destruction to the sea area. The included angle theta between the scraper 2 and the frame body 1 is 91.5-92 degrees. According to the difference of the growth habits of the shellfish, the depths of clams of the same variety in the sea area are nearly the same, when the clams are harvested, the included angle of 91.5-92 degrees can enable the scraper blade 2 to always maintain the vertical direction, the scraper blade 2 is always scraped horizontally along the bottom surface of the sea area, the scraping depths are the same, the purity of the harvested seedling seeds is improved, and meanwhile, the damage of scraping to seabed ecology is reduced. In addition, when the harvesting and catching ship drags the harvesting and catching device, the resistance can be reduced by the included angle of 91.5-92 degrees, so that the harvesting and catching device is kept stable, and the harvesting and catching efficiency is high.
The height of the scraper 2 is 15 +/-3 cm. The height of the scraper blade 2 of 15 plus or minus 3cm can not only maintain the effective scraping depth, but also facilitate the scraped seedlings and silt to smoothly enter the collecting net 3. The height is lower can lead to the scraper blade 2 not to scrape and get the seed, scrapes and gets the inefficacy, and highly higher can lead to again that the seed of scraping and silt can't all get into and collect in the net 3, and then leads to seed and silt to pile up at the lateral wall of scraper blade 2, and the influence is scraped and is got.
