Novel larva-bait separator for Macrobrachium rosenbergii

Abstract

The invention relates to a novel larva-bait separator for Macrobrachium rosenbergii. The separator includes a hopper body, a support, a discharge opening, a plurality of observation windows, and a plurality of sieve plates; the hopper body is cylindrical; the plurality of sieve plates include a 35-mesh sieve plate, a 55-mesh sieve plate, and a 70-mesh sieve plate; the plurality of sieve plates are arranged in the hopper body from top to bottom, and each of the sieve plates is horizontally arranged on a holder arranged in the hopper body; every sieve plate can be drawn out from the hopper body; and positions of an outer wall above the sieve plates, of the hopper body, are provided with one observation window each. The novel larva-bait separator is simple in structure, is clean in bait, is high in separation efficiency, can avoid pollution due to foreign matters, and can achieve up and down separation at the same time.

Description

technical field [0001] The invention relates to a bait separator, in particular to a novel bait separator for Macrobrachium rosenbergii larvae. Background technique [0002] At present, in many Macrobrachium rosenbergii seedling farms, the hatched Artemia worms and residues are easily mixed together, which makes the separation effect of the worms and residues poor, resulting in a lot of residues in the breeding ponds, serious water pollution, and the loss of worms and residues. Separation is slower. Contents of the invention [0003] In order to solve the above problems, the present invention provides a novel macrobrachium rosenbergii larval bait separator with simple structure, clean bait, high separation efficiency, no foreign matter pollution, and simultaneous upper and lower separation. [0004] The technical solution of the present invention is: the separator includes a hopper main body, a support frame, a discharge port, several observation windows, and several siev...
