AI Technical Summary
In existing technologies, the sorting process for snails and fish and shrimp relies on manual sorting, which is time-consuming and labor-intensive. It is especially difficult to meet production needs when processing on a large scale. In addition, traditional sieve screening can easily cause snails to get stuck in the sieve holes or fish and shrimp to get injured.
Design a separation and screening device including multi-layer screen frames and vibration components. Utilize the differences in screen aperture and the drive of a vibration motor, combined with spring buffer, to separate adult snails, juvenile snails, and fish and shrimp. Collect them independently through a collection box to reduce secondary sorting processes.
It significantly improves separation purity and efficiency, increasing the collection efficiency of adult snails, juvenile snails, and fish and shrimp by 3-5 times, reducing material accumulation and blockage, and lowering the risk of injury to fish and shrimp.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of aquaculture equipment, and in particular to a separation and screening device for snails and fish and shrimp. Background Technology
[0002] In the process of aquaculture, fishing and processing, snails (such as river snails and rock snails) are often mixed with fish and shrimp (such as small fish and shrimp), and need to be separated to meet the needs of classified breeding, sales or processing.
[0003] However, existing technologies have some problems: the current process of separating snails and fish and shrimp often relies on manual sorting, which is time-consuming and labor-intensive, especially when large-scale processing is difficult to meet production needs. In addition, traditional screen screening only separates through a single aperture, and the hard shells of snails are easily stuck in the screen holes, while fish and shrimp are easily crushed and injured due to their soft bodies. Therefore, it is necessary to provide a separation and screening device for snails and fish and shrimp to solve the above technical problems. Utility Model Content

Larger juvenile snails are intercepted and slide along the inclined surface into the juvenile snail collection box 12, while fish and shrimp smaller than 3-5mm and water pass through the second screen hole 8 and fall into the fish and shrimp collection box 13 at the bottom. The water accumulated in the box can be discharged in time through the bottom drain pipe 14, realizing the initial separation of fish and shrimp from water.
[0028] The working principle of the separation and screening device for snails and fish and shrimp provided by this utility model is as follows:
[0029] Implementation steps for the first innovation point:
[0030] Step 1: Place the mixture containing adult snails, juvenile snails and fish and shrimp into the first screen frame 5. After starting the vibration motor 92, the first screen frame 5 will vibrate continuously under the elastic support of the spring 4. Adult snails with a size greater than 8-12mm cannot pass through the first screen hole 6.
[0031] Step 2: With vibration, it moves towards the end of the first screen frame 5 and finally falls into the snail collection box 11. The material, young snails, fish, shrimp and water that pass through the first screen hole 6 fall into the second screen frame 7 below.
[0032] Implementation steps for the second innovation point:
[0033] Step 1: Because the second screen frame 7 is installed at an incline, gravity assists in the conveying process, and the water spray head 15 sprays water into the second screen frame 7. The sprayed water helps the fish and shrimp pass through, and the diameter of the second screen hole 8 is 3-5mm. Larger juvenile snails are intercepted and slide into the juvenile snail collection box 12 along the inclined surface.
[0034] Step 2: Fish and shrimp smaller than 3-5mm and water pass through the second sieve hole 8 and fall into the fish and shrimp collection box 13 at the bottom. The water in the box can be drained in time through the bottom drain pipe 14, thus achieving the initial separation of fish and shrimp from water.
