The utility model provides a kind of novel zooplankton harvester, comprises floating pump, spud pile, floating pump water inlet filter bag, tube connector, zooplankton collection net cage and inserted link.The small-power floating pump that the utility model adopts can regulate the underwater penetration of water pump by the weight adding diminishing in floating drum, the different water levels be adapted in the waters such as irrigation canals and ditches, river course or pond gathers zooplankton, overcome high-power submerged pump in working order under cause greatly and easily the problem that zooplankton stress be dead due to discharge, improve the collection survival rate of zooplankton; The water inlet filter bag of floating pump can prevent from foreign material, large-scale aquatic animal etc. from entering and block zooplankton collecting net cage, improves the efficiency of separation after zooplankton collection, reduces workload.The utility model zooplankton collecting efficiency is high, can make full use of the zooplankton resource in various poisons in freshwater, has efficient, easy, practical and is easy to the advantages such as popularization.

Description

A kind of novel zooplankton harvester
Technical field
The utility model relates to freshwater fish rearing of fingerling field, is specifically related to a kind of novel zooplankton harvester.
Background technology
The zooplankton of freshwater is widely distributed, has extremely strong fertility and adaptive capacity, is extremely important biological feed during aquaculture nursery is produced, although there is scientific research personnel to have developed Some substitute product, still has its irreplaceability at present.Particularly for some new, special products of famous brands, of extra fine quality freshwater fish, because it is live bait, comprehensive nutrition, is rich in the features such as unsaturated fatty acid, not polluted water and becomes the excellent bait of seed rearing, the parent of cultivation dealer is enjoyed to look at.
What generally adopt in current production is rely on the artificial towing zooplankton string bag to collect zooplankton, not only large, the consuming time work consuming of labour intensity, and the suitable waters gathered is little, efficiency is low; Adopt large-scale water flow generator to be gathered by screen frame and make suitable pickup area seriously limited, energy consumption is high and efficiency is lower; Pump power is excessive, collection net cage is too short and easily cause zooplankton mortality to adopt the collecting method of high powered water pump then to exist, and survival rate is low and fresh and alive degree is poor, and pump intake does not carry out prefiltration process and increases the workload of zooplankton sorting.
Summary of the invention
The utility model improves for the problems referred to above, namely the technical problems to be solved in the utility model be overcome existing zooplankton harvester large, the consuming time work consuming of labour intensity, energy consumption is high and efficiency is lower, and zooplankton gather after the shortcomings such as the low and fresh and alive degree of survival rate differs from.
Specific embodiments of the present utility model is: a kind of zooplankton harvester, comprises a floating pump, and the water inlet of described floating pump is provided with filter bag, and the delivery port of described floating pump is arranged with the net cage collected for zooplankton.
Further, described net cage is connected with the delivery port of floating pump through a tube connector.
Further, the tied rope of described net cage through net cage water inlet or buckle are fixed on the water side of tube connector.
Further, the mesh of described water inlet filter bag is 20 orders.
Further, described net cage is made up of 180 ~ 200 mesh sieve thin,tough silk, length 4.0 ~ 6.0 m.
Further, described net cage shape is cylindrical.
Further, described net cage diameter is 0.6 ~ 1.0 m.
Further, described floating pump comprises water pump and is arranged at the floating drum above water pump, and described floating pump side is provided with one for the spud pile of station pump position.
Further, it is characterized in that, described net cage end is provided with one for the inserted link of fixed cage rear end.
Compared with prior art, the utility model has following beneficial effect:
(1) the small-power floating pump that the utility model adopts itself is suspended in the middle of water body, the random object regulating the underwater penetration of water pump can be reached by the weight adding diminishing in floating drum, there is the advantages such as easy to use, energy saving, be adapted at gathering zooplankton in different waters, different water levels, improve zooplankton collecting efficiency;
(2) small-power floating pump (general about 0.75 kilowatt) can overcome high-power submerged pump in working order under cause greatly and easily the problem that zooplankton stress be dead due to discharge, improve the collection survival rate of zooplankton;
(3) the utility model adds a prefiltration mesh bag at the water inlet of floating pump, and object is to prevent foreign material, large-scale aquatic animal etc. from entering and blocks zooplankton to collect net cage, improves the efficiency of separation after zooplankton collection, reduces workload;
(4) length of zooplankton collection net cage is preferably 4.0 ~ 6.0 m, to ensure that zooplankton is had sufficient activity and backflow space after suction filtration network access case, success solves a difficult problem for its easy hypoxia death under high-density aggregation state, significantly improves the survival rate of zooplankton and fresh and alive degree;
(5) the utility model collects the mesh of the net cage of zooplankton by being 180 ~ 200 orders, because wheel animalcule size is generally 100 ~ 250 microns, the mesh of 180 ~ 200 order mesh sheet is less than 100 microns (mesh size of 150 order mesh sheet is then more than 100 microns), can ensure that the wheel animalcule (particularly as the small-sized wheel animalcule of fish open-mouthed bait) of most kind can be collected like this.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
In figure: 10-floating pump, 101-floating drum, 20-filter bag, 30-net cage, 40-spud pile, 110-water inlet, 120-delivery port, 121-tube connector, 50-inserted link.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
As shown in Figure 1, a kind of zooplankton harvester, comprises a floating pump 10, and floating pump 10 comprises water pump and is arranged at the floating drum 101 above water pump, reaches the random underwater penetration regulating water pump by the weight adding diminishing in floating drum 101.The water inlet 110 of described floating pump 10 is provided with filter bag 20, and the delivery port 120 of described floating pump 10 is through a tube connector 121 and for collecting the net cage 30 that zooplankton is collected.Net cage 30 opening part makes net cage 30 be fixed on the water side of tube connector 121 by tied rope or buckle.
