[0007] The vibrating screen has three layers, which are vibrating screen a, vibrating screen b and vibrating screen c from top to bottom.

[0008] The material guiding device is a material guiding trough arranged obliquely, and the material guiding trough comprises a material guiding trough a, a material guiding trough b and a material guiding trough c which are respectively connected to the vibrating screen a, the vibrating screen b and the vibrating screen c.

[0009] The mesh size of the vibrating screen a is 60 mm, the mesh size of the vibrating screen b is 50 mm, and the mesh size of the vibrating screen c is 40 mm.

[0010] Both sides of the vibration frame are provided with mounting plates, and the vibration motor is fixed on the mounting plates.

[0011] The beneficial effects of the present invention are: replacing manual screening, improving screening efficiency, and reducing labor costs and work intensity. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The following is combined with Figure 1-2 The present invention is further described:

[0016] An automatic screening device for aquatic products, wherein a discharging trough 5 is arranged at an angle at the bottom of a frame 1, and a discharging port is located at the lower end of the discharging trough 5, and three layers of obliquely arranged vibrating screens are arranged above the discharging trough 5, which are vibrating screen a8, vibrating screen b9 and vibrating screen c10 from top to bottom, and the apertures of the three layers of screens are 60 mm from top right to bottom 50mm and 40mm, the lower end outlet of the vibrating screen is respectively connected to the guide trough a11, the guide trough b12 and the guide trough c, the vibrating screen is located on the vibrating frame 3, and the middle parts of both sides of the vibrating frame 3 are provided with mounting plates 13, the vibration motor 4 is fixed on the mounting plates 13, the top of the frame 1 is provided with an end plate 7, and the end plate 7 is fixed with a guide column a, the bottom end of the spring 2 is sleeved on the guide column a and fixed to the end plate 7, the top of the spring 2 is connected to the angle joint 6, and the angle joint 6 is connected to the vibrating frame 3, and the vibrating frame 3 is flexibly connected to the frame 1 through the spring 2. Driven by the vibration motor 4, the vibrating frame 3 and the vibrating screen can vibrate, thereby achieving the purpose of vibration screening.

[0017] Taking scallops as an example, when screening, the scallops are first poured onto the high place of the tilted vibrating screen a8, the vibration motor 4 drives the vibrating screen to vibrate, the vibrating screen a8 drives the scallops thereon to vibrate, and the scallops move toward the lower end of the vibrating screen a8 while vibrating. Scallops with a size less than 60 mm fall onto the vibrating screen b9 below, and scallops with a size not less than 60 mm are screened out and enter the guide trough a11. The guide trough a11 is tilted, and the scallops thereon slide toward the lower end under the action of gravity and are collected by the next process; similarly, the vibrating screen b9 screens scallops with a size not less than 50 mm, and the vibrating screen c10 screens scallops with a size not less than 40 mm. The screened scallops are classified by size for breeding, and scallops with a size less than 40 mm are collected after passing through the discharge trough and thrown into the sea to grow on their own.

[0018] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
