Abstract
The utility model relates to a larval giant freshwater prawn bait separator. The separator comprises a hopper main body, a clapboard, an upper wide-meshed screen, a lower fine-meshed screen and a baiting pipe, wherein the hopper main body comprises an upper hopper and a lower hopper; the upper wide-meshed screen is arranged in the upper hopper; a lower conical hopper is arranged on the lower portion of the upper hopper; the lower fine-meshed screen is arranged in the lower hopper; a lower conical hopper is arranged on the lower portion of the lower hopper; the clapboard is arranged between the upper hopper and the lower hopper; the baiting pipe is connected to the lower portion of the lower conical hopper. The separator is simple in structure, clean in bait, high in separating efficiency and free from foreign matter pollution. The upper and lower hoppers can be separated at the same time. By screening incubated fairy shrimps twice, foreign matters such as decrustation and other residues of fairy shrimps can be removed, the purity of larval giant freshwater prawn bait fairy shrimps is ensured, and a breeding pond is prevented from being polluted by foreign matters. Meanwhile, the separator is designed into upper and lower layers, thereby isolating a separating flow, achieving an ideal effect and realizing convenience and rapidness.
Description
Technical field
The utility model relates to a kind of bait separator, relates in particular to a kind of Macrobrachium rosenbergii larvae bait separator.
Background technology
Current many Macrobrachium rosenbergii seeds field, fairy shrimp polypide and residue after hatching easily mix, and make polypide and residue separating effect bad, cause breeding residue in pond many, and water quality is subject to seriously polluted, and the separating rate of polypide and residue is slower.
Utility model content
The utility model for overcome the above problems provide a kind of simple in structure, bait is clean, separative efficiency is high, foreign pollute, up and down simultaneously separate Macrobrachium rosenbergii larvae bait separator.
The technical solution of the utility model is: described separator comprises hopper main body, dividing plate, upper wide-meshed screen, lower fine screen mesh and tremie pipe, described hopper main body comprises hopper and lower hopper, described upper wide-meshed screen is arranged in hopper, and described upper hopper bottom is upper cone hopper; Described lower fine screen mesh is arranged in lower hopper, described lower hopper bottom lower cone hopper, and described dividing plate is arranged between hopper and lower hopper, and described tremie pipe is connected to lower cone hopper bottom.
Described lower hopper is provided with slag notch.
Described upper wide-meshed screen is 35 orders, and lower fine screen mesh is 70 orders.
The utility model is simple in structure, bait is clean, separative efficiency is high, foreign pollutes, can separate by upper and lower warehouse simultaneously, cross sieve twice through the fairy shrimp hatching, can remove the foreign matters such as fairy shrimp decortication and other residue, ensure that Macrobrachium rosenbergii larvae bait fairy shrimp is pure, foreign pollutes breeds pond, separator designs is become to upper and lower double-layer structure simultaneously, and separation process is separated, both made separation reach ideal effect, convenient and swift again.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 is upper hopper, the 2nd, and upper wide-meshed screen, the 3rd, dividing plate, the 4th, upper cone hopper, the 5th, lower hopper, the 6th, lower fine screen mesh, the 7th, lower cone hopper, the 8th, tremie pipe, the 9th, slag notch, the 10th, feet.
Embodiment
A kind of Macrobrachium rosenbergii larvae bait separator, described separator comprises hopper main body, dividing plate 3, upper wide-meshed screen 2, lower fine screen mesh 6 and tremie pipe 8, described hopper main body comprises hopper 1 and lower hopper 5, described upper wide-meshed screen 2 is arranged in hopper 1, and described upper hopper 1 bottom is upper cone hopper 4; Described lower fine screen mesh 6 is arranged in lower hopper 5, described lower hopper 5 bottom lower cone hoppers 7, described dividing plate 3 is arranged between hopper 1 and lower hopper 5, described tremie pipe 8 is connected to lower cone hopper 7 bottoms, described lower hopper 5 is provided with slag notch 9, described upper wide-meshed screen 2 is 35 orders, and lower fine screen mesh 6 is 70 orders.
Bait fairy shrimp through hatching is at upper hopper 1 after first standing separation 20-30 minute, open dividing plate 3, allow the fairy shrimp in upper cone hopper 4 enter lower hopper 5, after whole bait enters lower hopper 5, close dividing plate 3, upper hopper 1 continues next step charging, standing separation operation, can carry out standing separation operation with lower hopper 5 simultaneously, ensure that Macrobrachium rosenbergii larvae bait fairy shrimp is pure, foreign pollutes breeds pond.
