An automatic processing device for Pomacea canaliculata egg masses

Abstract

The present invention provides an automatic device for processing golden apple snail egg masses. It solves the problem of low efficiency in manual egg mass removal. When in use, the present invention uses a fixed rod inserted in the water, and a counterweight drives a pressure plate to move upward. The counterweight floats on the water surface, and there is a certain distance between the pressure plate and the water surface. The golden apple snail climbs upward via the fixed rod inserted in the water. The pressure plate and a ring of retaining edges fixed on the outer circumference of the pressure plate prevent the golden apple snail from continuing to climb upward on the pressure plate, and lays eggs on the fixed rod below the pressure plate. At night, moisture in the air condenses on the hydrogel plate and slides into the sponge for storage. The weight on the pressure plate gradually increases, and the pressure plate moves downward to scrape off all egg masses on the fixed rod. The egg masses fall into the water and die, completing the egg mass cleaning. The device is convenient to use, simple in structure, and highly practical.

[0019] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: Figure 1-6 As shown, an automatic processing device for golden apple snail egg masses is characterized in that it includes a fixed rod 1 and a pressure plate 2 set on the outer periphery of the fixed rod 1, a cavity 3 extending along the length direction of the fixed rod 1 and passing through the fixed rod 1 is opened in the fixed rod 1, a circle of retaining edges 4 is fixedly provided on the outer periphery of the pressure plate 2, the retaining edges 4 are gradually bent downward from the inside to the outside, and the outer diameter of the retaining edges 4 is larger than the outer diameter of the above-mentioned pressure plate 2, the upper end of the pressure plate 2 is fixedly provided with a circle of convex edges 5 enclosed in the outer periphery of the above-mentioned fixed rod 1, the diameter of the convex edge 5 is larger than the diameter of the above-mentioned fixed rod 1 and smaller than the outer diameter of the above-mentioned pressure plate 2, and a fixed arrangement is provided on the pressure plate 2. There is a circle of sponge 6 surrounding the outer periphery of the above-mentioned fixed rod 1, and the sponge 6 is located in the above-mentioned convex edge 5. A hydrogel plate 7 is fixedly provided on the sponge 6. A counterweight block 8 is movably provided in the cavity 3, which can move along the length direction of the cavity 3 and drive the above-mentioned pressure plate 2 to move upward. The counterweight block 8 floats on the water surface. The sum of the weight of the pressure plate 2, the retaining edge 4, the convex edge 5, the sponge 6 and the hydrogel plate 7 is less than the weight of the above-mentioned counterweight block 8. A plurality of pull ropes 9 are provided between the convex edge 5 and the above-mentioned counterweight block 8. The two ends of the pull rope 9 are respectively located on the inner and outer sides of the above-mentioned fixed rod 1 and the pull rope 9 is mounted on the upper end of the above-mentioned fixed rod 1. The counterweight 8 floats on the water surface, and the lower end surface of the counterweight 8 is in contact with the water surface. When the weight above the pressure plate 2 gradually increases, the position where the water surface and the counterweight 8 are in contact has a certain suction force on the counterweight 8, and the counterweight 8 cannot easily leave the water surface. The weight of the pressure plate 2 continues to increase until the counterweight 8 leaves the water surface. At this time, the weight on the pressure plate 2 is much greater than the weight of the counterweight 8. The pressure plate 2 moves downward quickly and scrapes off the egg masses attached to the outer wall of the fixed rod 1 during the movement.

[0020] The pressure plate 2 is driven upward by the fixed rod 1 inserted in the water through the counterweight 8, and the counterweight 8 floats on the water surface. There is a certain distance between the pressure plate 2 and the water surface. The golden apple snail climbs upward through the fixed rod 1 inserted in the water, and the pressure plate 2 and a circle of retaining edges 4 fixedly set on the outer periphery of the pressure plate 2 prevent the golden apple snail from continuing to climb upward at the pressure plate 2, and lay eggs on the fixed rod 1 below the pressure plate 2. At night, the temperature drops, and the moisture in the air condenses on the hydrogel plate 7 and slides into the sponge 6 for storage, and the weight on the pressure plate 2 gradually increases. , until the weight on the pressure plate 2 is greater than the weight of the counterweight 8, the pressure plate 2 moves downward and scrapes off all the egg masses on the fixed rod 1, the egg masses fall into the water and die, and the egg mass cleaning is completed. During the day, after sunlight, the temperature gradually rises, the water in the sponge 6 evaporates, and the weight on the pressure plate 2 gradually decreases. When it is less than the weight of the breeding block, the counterweight 8 moves downward and drives the pressure plate 2 to move upward through the pull rope 9. The pressure plate 2 is again above the water surface, and the collection and processing of the golden apple snail egg masses can be automatically completed. It is more convenient to use, simple in structure, and more practical.

[0021] A scraper 10 is fixedly mounted on the lower end of the pressure plate 2. The scraper 10 has a diameter that gradually decreases from top to bottom. The diameter of the upper end of the scraper 10 is larger than the diameter of the fixed rod 1. The inner wall of the lower end of the scraper 10 abuts against the outer wall of the fixed rod 1. By abutting the lower end of the scraper 10 against the outer wall of the fixed rod 1, the egg mass on the fixed rod 1 can be relatively completely removed, and any remaining egg mass can be prevented from adhering to the outer wall of the fixed rod 1.

[0022] The upper end of the fixed rod 1 is provided with multiple openings 11. A roller 12 is rotatably mounted within each opening 11. The pull cord 9 is clipped onto this roller 12, creating a one-to-one correspondence between the pull cord 9, openings 11, and rollers 12. Four pull cords 9, four openings 11, and four rollers 12 are provided, evenly distributed on the flange 5 and the fixed rod 1. The rollers 12 significantly reduce friction between the pull cord 9 and the fixed rod 1, ensuring smoother movement of the counterweight 8 and the pressure plate 2.

[0023] The sponge 6 has a curved surface 13 at its upper end, which gradually bends downward. The hydrogel plate 7 is provided with multiple curved surfaces 13 that are evenly interlocked with the sponge 6. The hydrogel plate 7 bends downward from its center along its length, with its lower end resting against the curved surfaces 13. When water condenses on the hydrogel plate 7, the downwardly curved hydrogel plate 7 causes the condensed water droplets to slide down the sides of the hydrogel plate 7 and drip onto the sponge 6, significantly accelerating the condensation speed of the water droplets on the hydrogel plate 7.

A counterweight 8 is movably provided in the above-mentioned cavity 3, which can move along the length direction of the cavity 3 and drive the above-mentioned pressure plate 2 to move upward. The counterweight 8 floats on the water surface. The sum of the weight of the pressure plate 2, the retaining edge 4, the convex edge 5, the sponge 6 and the hydrogel plate 7 is less than the weight of the above-mentioned counterweight 8. A plurality of pull ropes 9 are provided between the above-mentioned convex edge 5 and the above-mentioned counterweight 8. The two ends of the pull rope 9 are respectively located on the inner and outer sides of the above-mentioned fixed rod 1 and the pull rope 9 is mounted on the upper end of the above-mentioned fixed rod 1. The counterweight 8 floats on the water surface, and the lower end surface of the counterweight 8 is in contact with the water surface. When the weight above the pressure plate 2 gradually increases, the position where the water surface and the counterweight 8 are in contact has a certain suction force on the counterweight 8, and the counterweight 8 cannot easily leave the water surface. The weight of the pressure plate 2 continues to increase until the counterweight 8 leaves the water surface. At this time, the weight on the pressure plate 2 is much greater than the weight of the counterweight 8. The pressure plate 2 moves downward quickly and scrapes off the egg masses attached to the outer wall of the fixed rod 1 during the movement.

[0025] The pressure plate 2 is driven upward by the fixed rod 1 inserted in the water through the counterweight 8, and the counterweight 8 floats on the water surface. There is a certain distance between the pressure plate 2 and the water surface. The golden apple snail climbs upward through the fixed rod 1 inserted in the water, and the pressure plate 2 and a circle of retaining edges 4 fixedly set on the outer periphery of the pressure plate 2 prevent the golden apple snail from continuing to climb upward at the pressure plate 2, and lay eggs on the fixed rod 1 below the pressure plate 2. At night, the temperature drops, and the moisture in the air condenses on the hydrogel plate 7 and slides into the sponge 6 for storage, and the weight on the pressure plate 2 gradually increases. , until the weight on the pressure plate 2 is greater than the weight of the counterweight 8, the pressure plate 2 moves downward and scrapes off all the egg masses on the fixed rod 1, the egg masses fall into the water and die, and the egg mass cleaning is completed. During the day, after sunlight, the temperature gradually rises, the water in the sponge 6 evaporates, and the weight on the pressure plate 2 gradually decreases. When it is less than the weight of the breeding block, the counterweight 8 moves downward and drives the pressure plate 2 to move upward through the pull rope 9. The pressure plate 2 is again above the water surface, and the collection and processing of the golden apple snail egg masses can be automatically completed. It is more convenient to use, simple in structure, and more practical.

[0026] A scraper 10 is fixedly mounted on the lower end of the pressure plate 2. The scraper 10 has a diameter that gradually decreases from top to bottom. The diameter of the upper end of the scraper 10 is larger than the diameter of the fixed rod 1. The inner wall of the lower end of the scraper 10 abuts against the outer wall of the fixed rod 1. By abutting the lower end of the scraper 10 against the outer wall of the fixed rod 1, the egg mass on the fixed rod 1 can be relatively completely removed, and any remaining egg mass can be prevented from adhering to the outer wall of the fixed rod 1.

[0027] The upper end of the fixed rod 1 is provided with multiple openings 11. A roller 12 is rotatably mounted within each opening 11. The pull cord 9 is clipped onto this roller 12, creating a one-to-one correspondence between the pull cord 9, openings 11, and rollers 12. Four pull cords 9, four openings 11, and four rollers 12 are provided, evenly distributed on the flange 5 and the fixed rod 1. The rollers 12 significantly reduce friction between the pull cord 9 and the fixed rod 1, ensuring smoother movement of the counterweight 8 and the pressure plate 2.

[0028] The hydrogel plate 7 surrounds the outer periphery of the fixing rod 1 and rests against the upper end surface of the sponge 6. The hydrogel plate 7 is provided with a plurality of through-holes 14 extending therethrough, the through-holes 14 covering the entire hydrogel plate 7. The through-holes 14 extending therethrough significantly increase the area of water condensation on the hydrogel plate 7, effectively improving the efficiency of water condensation. Furthermore, water droplets condensed within the through-holes 14 on the hydrogel plate 7 slide directly downward through the through-holes 14 onto the sponge 6 and are absorbed by the sponge 6. This significantly improves the efficiency of water condensation, allowing the weight on the pressure plate 2 to be increased rapidly.
