The front surface inside the slot 8 extends outside the screening box 1. Inside the slot 8, a screening box 2 is installed. The screening box 2 corresponds to the feed hopper 4. Below inside the screening tank, a draw slot 6 is provided. The front surface inside the draw slot 6 extends outside the screening box 1. Inside the draw slot 6, a receiving box 7 is inserted. At the center of the front surface of the receiving box 7, a handle slot is provided; During operation, first make the rubber pad at the bottom of the screening box 1 fit with a flat ground so that the device is stably placed. And through the rubber pad, certain buffering can be carried out when the screening box 1 vibrates for screening. In this way, the screening box 1 can be screened more smoothly during vibration screening, improving the screening efficiency. And after the device is stably placed, the lobsters to be screened are poured into the screening box 1 through the feed hopper 4. Then the lobsters enter the receiving box 7 through the hierarchical screening of the two screening boxes 2. And during the screening process, the screening box 2 can vibrate, making the screening efficiency of the device relatively high. Then after the screening is completed, the receiving box 7 and the screening box 2 can be pulled out to take out the screened lobsters, which is convenient to use and has a relatively high screening efficiency.

A continuous limiting groove is opened on the outer surface of the ring 22. The side of the extrusion block 20 is clamped inside the limiting groove. During operation, the screening box 2 can be stably installed with the screening box 1 by inserting the other end of the extrusion rod 19 into the jack 27. And during vibration screening, the screening box 2 is not likely to move, and it can avoid affecting the screening of lobsters. At the same time, when the screening plate 11 is to be disassembled and replaced with a new one, first disassemble the screening box 2 from the inside of the screening box 1. When disassembling, rotate the handle 3 to make the threaded rod 21 rotate. Then the threaded rod 21 rotates to drive the ring 22 to rotate, so that the ring 22 is disengaged from the extrusion and limitation of the extrusion block 20. And then the extrusion block 20 and the extrusion rod 19 will be extruded by the sliding of the sliding ring 26 under the action of the rebounding force of the originally compressed first spring 25. When the end of the extrusion rod 19 is removed from the jack 27, the insertion rod can be disengaged from the limiting installation of the screening box 2. Then the screening box 2 can be removed from the screening box 1 for disassembly and removal, which is convenient for subsequent disassembly of the screening plate 11.
