Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in figures 1-6, a fry sieving mechanism is including enclosing frame (1) and screen cloth (2), screen cloth (2) install in enclose frame (1), just the edge of screen cloth (2) respectively with the baffle inner wall that encloses frame (1) offsets, the top and the bottom of enclosing frame (1) are provided with the opening, screen cloth (2) are a plurality of assembled unit (2a) and constitute along length direction end to end connection, wherein the vertical length of assembled unit (2a) is greater than its horizontal length.

Because the normal swimming of fry is in the horizontal direction, most of the current screens are semicircular, and smaller fry can only swim out of the screens from the side walls of the screens, which greatly influences the screening of the fry.

The utility model discloses a screen cloth (2) comprise a plurality of assembled element (2a) for a plurality of screen cloth walls can appear in screen cloth (2) on the vertical direction, and the screen cloth is walked out from the horizontal direction to the fry that conveniently is less than specification and dimension, can not cause the influence to the safety of fry when improving screening efficiency.

The vertical length of the combined unit (2a) is larger than the horizontal length of the combined unit, so that the length of the screen wall can be increased, and the fry can conveniently swim out of the screen.

When in use, the utility model is placed in water, then the fish fry is poured into the screen (2), is static for about 10 minutes, and the smaller fish fry can be followed the fish fry that accords with the size specification is left after going out in the mesh of screen (2).

In example 1, the longitudinal section of the combination unit (2a) has a rectangular structure.

The space of the screen (2) formed by the combined units (2a) with rectangular sections in the horizontal direction is enlarged, more fish fries can be accommodated, and larger swimming space is provided for the fish fries,

the longitudinal section of the combined unit (2a) in the embodiment 2 is a triangular structure.

Adopt the screen cloth that triangle-shaped cross-section's modular unit (2a) are constituteed, in this embodiment, the accommodation space under the vertical direction from the top down of screen cloth (2) reduces gradually for the bottom space reduces, and the bottom fry can accelerate the fry to move about to the outside direction of screen cloth (2) because the space reduces, accelerates screening efficiency.

In example 3, the longitudinal section of the combination unit (2a) is a wave-shaped structure.

The sieve formed by the combined units (2a) with the wavy cross sections is adopted, in the embodiment, the accommodating space of the sieve (2) from top to bottom in the vertical direction is gradually reduced, and the bottom fries are accelerated to swim out of the sieve (2). And the bottom of the wave-shaped combined unit (2a) is of an arc-shaped structure, so that the fry is not easily damaged in the embodiment compared with the embodiment 2.

Preferably, a handle (3) is further arranged in the enclosure frame, and two ends of the handle (3) are respectively fixed on the front wall and the rear wall of the enclosure frame (1).

Be provided with the handle, can be with through the handle when receiving the fish the utility model discloses the pull-up surface of water can make the better power of having an effect of user.

Preferably, the floating assembly (4) is arranged around the top of the enclosure frame (1).

Preferably, the floating assembly (4) is a hollow plastic tube.

Preferably, the floating assembly (4) is a plastic foam.
