Detailed Description

Embodiments of the present utility model will be described below with reference to the accompanying drawings in the embodiments of the present utility model.

Example 1

Referring to fig. 1-3, a floating type fry separating screen comprises a screen frame 1, wherein the screen frame 1 comprises four connecting pipes 101 and four elbow sleeves 102, and the four connecting pipes 101 and the four elbow sleeves 102 are connected in a sealing manner to form a rectangular floating body for floating the screen frame 1 on the water surface; the screen 2 is fixedly connected to the bottom end of the screen frame 1 and is used for screening fish seedlings; the screening holes are uniformly formed in the screen 2 and used for the fish fries to pass through.

Above-mentioned technical scheme can reach through the showy body reel 1 that sets up can provide great buoyancy, can float at the surface of water certainly when the fry screening, need not artifical handheld, effectively avoids because the fry of screening is too much, leads to screen cloth 2 overweight, the condition of sinking appears, and is more convenient laborsaving, has reduced the damage of fry, has promoted the technological effect of screening efficiency effectively.

Example 2
