Description
Technical field
The utility model relates to separating tool manufacturing technology field in taxonomic identification, particularly relates to the device of a kind of effective separating fish-egg prelarva fast.
Background technology
The fish early life history stage as an important step in its whole history of life, its survival rate be directly connected to fish year border magnitude of recruitment size, be cause Population fluctuation and age composition change main cause.In recent years, its attention rate improves constantly, and numerous researcher has carried out gathering investigation to fish egg and larva in different waters.
In sampling process, fish egg and larva is caught by netting gear simultaneously, and it is the first step of carrying out qualification in laboratory that both screenings are separated.But because fish eggs and larvae sample is less, be not easily distinguishable, researcher needs with suction pipe etc. usually by the sucking-off from the biased sample of fish egg and larva of one one, fish-egg ground, wasting time and energy so very, repeatedly draws and has certain destruction to sample, and the possibility of omitting sample is larger.
Utility model content
Technical problem to be solved in the utility model is to provide the device of a kind of fast effectively separating fish-egg prelarva, can lot splitting, and distinguishes thoroughly, less to sample injury degree.
The utility model solves the technical scheme that its technical problem adopts: the device providing a kind of effective separating fish-egg prelarva fast, comprise specimen cup, connecting ring, bolter and collection cups, described specimen cup both ends open, the opening of upper end is the entrance of fish eggs and larvae biased sample in separation process, and the opening part of lower end is provided with bolter; Described bolter has the rim of a cup of described collection cups; Described connecting ring is arranged on the junction of the described opening of specimen cup lower end and the rim of a cup of collection cups, and the bolter in the middle of specimen cup and collection cups and both is linked to be an entirety.
The opening diameter of described specimen cup upper end is greater than the opening diameter of lower end.
The open outside of described specimen cup lower end is provided with the first screw thread; The rim of a cup outside of described collection cups is provided with the second screw thread; Upper inner screw thread and first screw thread of described connecting ring inwall match, and lower inside screw thread and the second screw thread match.
Described bolter is made up of upper and lower two-layer retainer ring and the mesh screen be fixed in two-layer retainer ring.
Described retainer ring adopts elastomeric material to make.
Described mesh screen is by silk screen cloth cutting gained.
Described specimen cup and collection cups all adopt transparent material to make.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the utility model compared with prior art, has following advantage and good effect: what the utility model can be simple and quick carries out lot splitting, and distinguishes thoroughly, less to sample injury degree.The utility model structure is simple, and material is easy to obtain, and spends less and is convenient to a large amount of production, and dismantling easy, being beneficial to and carrying and receive.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of retainer ring in the utility model;
Fig. 3 is the structural representation of mesh screen in the utility model.
Embodiment
Below in conjunction with specific embodiment, set forth the utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of the utility model.In addition should be understood that those skilled in the art can make various changes or modifications the utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read the utility model instruction.
Embodiment of the present utility model relates to the device of a kind of effective separating fish-egg prelarva fast, as shown in Figure 1, comprise specimen cup 1, connecting ring 2, bolter 3 and collection cups 4, described specimen cup 1 both ends open, the opening of upper end is the entrance of fish eggs and larvae biased sample in separation process, and the opening part of lower end is provided with bolter 3; Described bolter 3 has the rim of a cup of described collection cups 4; Described connecting ring 2 is arranged on the junction of the described opening of specimen cup 1 lower end and the rim of a cup of collection cups 4, and the bolter 3 in the middle of specimen cup 1 and collection cups 4 and both is linked to be an entirety.Whole device adopts cylinder design, transparent toughened glass material is used to make specimen cup and collection cups, observe sample when whole clearing contributes to operation, the material of safety glass has certain hardness and toughness, and material corrosion resistance extends the service life of separator.
Specimen cup 1 is the entrance of fish eggs and larvae biased sample in separation process, and thicker lower end, profile upper end is comparatively thin, and both ends open, there is screw thread end opening outside, corresponding with connecting ring upper inside wall screw thread, is interconnected.Specimen cup 1 upper end thicker part position internal diameter 20cm, high 7cm, thinner section position, lower end external diameter 12cm, high 3cm, end opening outside screw height 0.8cm.
Connecting ring 2 inwall all has screw thread up and down, its upper inner screw thread is corresponding with specimen cup 1 end opening external screw-thread, the screw thread of its underpart inside thread and collection cups 4 rim of a cup outside coincide mutually, by spiral, the bolter 3 in the middle of specimen cup 1 and collection cups 4 and both is linked to be an entirety.Connecting ring 2 internal diameter 12cm, high 2cm, connecting ring inwall has the screw thread of high 0.8cm up and down respectively, matches respectively with specimen cup end opening external screw-thread and collection cups rim of a cup external screw-thread.
Bolter 3 is made up of with the mesh screen 6 be fixed therein upper and lower two-layer retainer ring 5.The external diameter of retainer ring and mesh screen is 12cm, the height at bolter edge (two-layer retainer ring and mesh screen) is 0.4cm, retainer ring is elastomeric material composition, there is certain elasticity and toughness, can be fixed together closely with mesh screen, mesh screen can use silk screen cloth cutting gained, and mesh screen pore size is chosen according to the diameter of institute's separating fish-egg.
