At this time, the compression spring 209 rebounds and drives the leftmost baffle frame 206 to move up to block the middle screening net 205 and the leftmost screening net 205. Then, the aquatic feed passes through the middle screening net 205 for screening. When the middle screening is completed, Then the electric push rod 215 is reset, and the rope 210 on the leftmost baffle frame 206 is pulled again. At this time, the baffle frame 206 moves down to release the blockage of the leftmost screening net 205 and the middle screening net 205. Then, with the vibration of the screening box 202, the aquatic feed is moved to the leftmost screening net 205 for screening. Through the above screening operation, each group of template screens with different apertures is temporarily blocked, and small particles will not fall from the large-aperture screen, thereby improving the screening results, improving the use effect of the device, and meeting actual use needs.

Since the screening box 202 is designed with an inclined structure, the screened aquatic feed can be moved better, and the screened aquatic feed is finally discharged from the discharge port 204. When the screening of small-particle aquatic feed is completed, the electric push rod 215 is started to shrink, and the U-shaped slide 214 is driven to slide in the screening box 202 through the slide rail. As the U-shaped slide The movement of the frame 214 drives the fixed block 213 to move, and the rope 210 is pulled by the fixed block 213, and the baffle frame 206 is driven to move downward by the rope 210, and the baffle frame 206 slides on the surface of the limit rod 208, and compresses the compression spring 209 until the upper surface of the baffle frame 206 is flush with the surface of the screening net 205, and the contraction of the electric push rod 215 is stopped. At this time, the two groups of screening nets 205 on the far right are unblocked. With the vibration of the screening box 202, the aquatic feed on the screening net 205 on the far right moves to the middle screening net 205. At the same time, when the baffle frame 206 on the far right moves downward, the rope 210 on the other group of baffle frames 206 is in a released state. At this time, the compression spring 2 09 rebounds and drives the leftmost baffle frame 206 to move up to block the middle screening net 205 and the leftmost screening net 205, and then screens through the middle screening net 205. When the middle screening is completed, the electric push rod 215 is reset, and the rope 210 on the leftmost baffle frame 206 is pulled again. At this time, the baffle frame 206 moves down to release the blockage between the leftmost screening net 205 and the middle screening net 205. Then, with the vibration of the screening box 202, the aquatic feed is moved to the leftmost screening net 205 for screening. Through the above screening operation, each group of template screens with different apertures is temporarily blocked, and small particles will not fall from the large-aperture screen, thereby improving the screening effect. The effect of the device is improved and the actual use needs are met. The threaded top rod 217 on the fixed frame 216 is rotated until the bottom end of the threaded top rod 217 passes over the top of the screening box 202, thereby releasing the resistance to the screening net 205, making it convenient to remove the screening net 205 and replace the screening nets 205 with different apertures, thereby further improving the practicality and flexibility of the device. The screened aquatic feed is discharged through the discharge port 204. In this process, the electric push rod 221 is started to drive the receiving box 218 to move on the ground through the moving wheel 220. Since the partition 219 divides the receiving box 218 into a plurality of chambers, the screened aquatic feed can be collected in different chambers respectively, without manual collection, thereby reducing the labor intensity of the staff.Further improve the use effect of the device.
