Description

Technical Field

[0001] The invention belongs to the technical field of Manila clams, and in particular relates to a Manila clams spawning and egg washing device and method. Background Art

[0002] Philippine clam: also commonly known as variegated clam or Philippine clam, the shell length is 2.5-5.7 cm. The commercial size is an average of 40 mm. It is a common shellfish. The shell is solid, the shell valves are equal on the left and right; the two sides are unequal, and the beak on the top of the shell is located in the front half; the shape is slightly oval. The ligament is embedded and does not protrude from the shell surface. The wide and thick brown oval arched body extends almost to half of the rear edge. It is a shellfish seafood. It grows rapidly, has a short breeding cycle, strong adaptability (wide temperature, wide salt, wide distribution), and can survive long out of water. It is an excellent shellfish suitable for artificial high-density breeding. It is one of the four major farmed shellfish in China. It is a species from the subtropical to low cold temperate zone of the western Pacific Ocean, and is distributed in the temperate zone of Europe. Its breeding began with traditional fishing activities in these areas by collecting wild clam seed.

[0003] At present, when spawning and washing eggs of Manila clams, Manila clams are generally dropped under a bamboo raft through a net bag, and then the bamboo raft is slid to carry out spawning of Manila clams during the sliding process. However, this method can only be used for larger aquaculture rivers or moors, and is not applicable to aquaculture ponds with smaller areas. In addition, relying on artificial movement of Manila clams on the water surface cannot continuously and effectively enable Manila clams to move evenly on the water surface and change their moving positions at all times, which results in uneven distribution of fertilized eggs. At the same time, after spawning, a lot of mucus will float on the upper water surface, and the fertilized eggs need to be washed. The traditional method is to discharge the upper water surface through water inlet and outlet, but it is easy to cause more fertilized eggs to be discharged together, reducing the effect of spawning and washing eggs. For this reason, we propose a Manila clam spawning and egg washing device and method. Summary of the invention

2. The spawning and egg washing method of the spawning and egg washing device of the Manila clam according to claim 1, characterized in that: The following steps are involved: S1: The annular plate (1) is fixed on a culture pond of corresponding size, and the push rod motor (22) is started, so that the push rod motor (22) drives the support plate three (5) to move, so that the support plate three (5) drives the driving motor (6) to rotate, and the driving motor (6) drives the first shaft (7) and the connecting plate one (8), the connecting plate two (9), and the connecting body (14) to move upward, and then the box door is opened, and the Philippine clam is placed in the connecting channel (26) inside the connecting body (14), and then the box door is closed, and the push rod motor (22) is started to drive the support plate three (5) Move downward to allow the connector (14) to enter the water surface, then start the drive motor (6), the drive motor (6) drives the first shaft (7) to rotate, the first shaft (7) drives the connecting plate (8) to rotate, the connecting plate (8) drives the adjustment block (11) and the connector (14) to rotate, so that the connector (14) drives the Philippine clam to move evenly inside the culture pond, accelerates the spawning and sperm discharge of the parent clam, and can effectively promote the dispersion and fertilization of the sperm and eggs discharged by the parent clam, so that the fertilized eggs can be evenly dispersed to avoid the fertilized eggs from piling up in one place; S2: At the same time, the connecting plate 1 (8) drives the second shaft (10) to rotate along the annular plate (1), and the second shaft (10) drives the adjusting gear (12) to rotate. When the adjusting gear (12) passes through the arc plate (19) area, the meshing transmission between the adjusting gear (12) and the adjusting rack (20) drives the second shaft (10) to rotate. The second shaft (10) drives the adjusting block (11) to move through the thread transmission, so that the adjusting block (11) drives the connecting body (14) and the filter plate (27) and the filter hole (28) to move, so that the connecting body (14) drives the Philippine clam to move on the water surface at different positions inside the culture pond. Uniform rotation, when the adjustment block (11) moves to the leftmost or rightmost position, when it moves to the leftmost position, the adjustment block (11) drives the squeezing plate 1 (24) to squeeze the inching switch 1 (23), starts the stepping motor 1 (16), and the stepping motor 1 (16) drives the adjustment plate 1 (17) to rotate, the adjustment plate 1 (17) drives the adjustment plate 2 (18) to rotate, the adjustment plate 2 (18) drives the arc plate (19) and the adjustment rack (20) to flip, and when the adjustment gear (12) passes through the adjustment rack (20) area again, the second shaft body (10) rotates in the opposite direction, and the eggs are laid in a reciprocating cycle and evenly distributed; S3: After the spawning in step S2 is completed, the Manila clam in the connecting channel (26) is taken out, and the stepper motor 2 is started. The stepper motor 2 drives the third shaft (31) to rotate, and the third shaft (31) drives the guide gear (33) to rotate. At the same time, the third shaft (31) drives the winding roller to rotate, and the winding roller drives the filter cloth (36) to perform a zooming process. At the same time, the meshing transmission between the guide gear (33) and the guide rack (35) drives the slide bar (34) to move, and the slide bar (34) drives the fixed bar 1 (37) and the fixed bar 2 (38) to move, so that the fixed bar 2 (38) drives the guide bar to move, and the guide bar pulls the filter cloth (36) to move, so that the guide bar enters the positioning groove (40 ) inside, so that the filter cloth (36) intercepts the connecting channel (26), then starts the push rod motor (22), the push rod motor (22) drives the support plate three (5) to move, so that the support plate three (5) drives the connecting body (14) to move, and part of the connecting body (14) moves to the water surface, so that the mucus on the surface of the breeding pool enters the inside of the connecting channel (26) along with the water source, and finally the mucus on the water surface is collected by the filter cloth (36). Since the connecting body (14) continues to circulate inside the breeding pool, the pool water moves, effectively improving the hatching rate, thereby completing the egg washing operation of the fertilized eggs, and finally, at regular intervals, the box door is opened to clean the inside of the connecting channel (26) and the filter cloth (36).
