Description
Technical field
The present invention relates to Sipunculus nudus cultural technique fields, specially a kind of Sipunculus nudus high-density breeding pond.
Background technique
Sipunculus nudus is a kind of high nutrition food materials that mouthfeel is very delicious, while being Chinese medicine rare simply again,
With the growing interest of people, the wild Sipunculus nudus of script is difficult to meet the market demand, at this moment with regard to being propagated artificially
, special cultivation place is needed during artificial breeding, generally uses two kinds of cultural methods, and one is cultivation coastal
On beach, one is cultivation in box for breeding, however both cultural methods all have certain problems:
When mudflat aquaculture, as technology is numbered: a kind of 9711305 nude Sipunculus nudus beach high-yield cultivation method skills proposed
Art, proposed in every 200 square metres be labeled as a culturing area, while being cultivated in the region, however due to edge
Seabeach applies the substrate do not fixed, and resulting in taking Sipunculus nudus its depth taken is more than 40cm, significantly increases digging
Difficulty is taken, cost of labor is increased；
And when being cultivated with box for breeding, such as application No. is a kind of box Sipunculus nudus cultivation that CN201810424653.0 is proposed
Method, in the method, using the cultivation measure of fountain, although rainwater is made to cover grains of sand layer Shamian Island, for a long time
Breeding process in, water body flow is poor, the phenomenon that be easy to causeing stagnant water, influences the growth of Sipunculus nudus, can lead when serious
It causes Sipunculus nudus to stop growing, while needing what is be timed to change water, the amount of labour is larger；
For another example technology is numbered: a kind of 11664976 nude Sipunculus nudus workshop aquaculture pond manufacturing technologies proposed, using cultivation
Pond is cultivated, while being combined with the design of water inlet pipe and drainpipe, can drive inside water body flowed, however such do
Method there is water inlet position it is single, there are problems that dead angle in the actual use process, so that the hair of stagnant water phenomenon can be generated
It is raw, simultaneously because water inlet pipe using draining from top to bottom, is easy the internal grains of sand being washed into side, influences device
It uses, then the patent does not have the function of cycle operation, wastes a large amount of water body, higher cost；
For another example application No. is a kind of workshop cultivation apparatus of Sipunculus nudus disclosed in CN201810923767.X, use cultivation
Slot is cultivated, while being furnished with water circulation mechanism, however during use, since feed pipe is in the upper of breeding trough
Side, in water inlet, the draining of water body from top to bottom is easy the phenomenon that internal grains of sand are washed into side, form puddle, simultaneously
Since grains of sand itself belong to one of filtering material, when water body flows wherein, mobility is poor, and which results in inflows
Seldom, prolonged use is easy to appear the generation of stagnant water phenomenon.
So we have proposed a kind of Sipunculus nudus high-density breeding pond, in order to solve the problems, such as to propose among the above.
Summary of the invention
The purpose of the present invention is to provide a kind of Sipunculus nudus high-density breeding ponds, to solve above-mentioned background technique proposition
Currently on the market Coastal beach cultivation Sipunculus nudus there are the amount of labour greatly and box for breeding cultivate Sipunculus nudus there are water body flows
Very poor problem.
To achieve the above object, it the invention provides the following technical scheme: a kind of Sipunculus nudus high-density breeding pond, including supports

Booster pump is connected, and intake pipe is equipped with above booster pump, and intake pipe runs through aquaculture pond, the inside of the aquaculture pond
It is provided with grains of sand layer, drainpipe is installed, and the end of drainpipe and intake pipe is provided with filtering on the right side of the aquaculture pond
Web plate, while the top of grains of sand layer is arranged in intake pipe.
It is preferred that the sparge pipe design in rectangular configuration, and be parallel to each other between sparge pipe and sparge pipe, and sparge pipe
Gap between sparge pipe is 20cm-80cm.
It is preferred that the water jet includes connecting tube, sealing ring, mounting blocks, spring, stifled ball, inner end cap, the first filtering
Net, outer end cap, the second filter screen and water jet, and sealing ring is installed, and inlay on the outside of connecting tube above connecting tube
There are mounting blocks, and stifled ball is connected with by spring in the middle part of the lower section of mounting blocks, while the diameter of stifled ball is greater than connecting tube most
Small internal diameter, and stifled ball constitutes bascule, and the upper surface flush with each other of the upper surface of connecting tube and mounting blocks by spring,
And the outside of connecting tube is in thread-like structure, while water jet is equally distributed on the top of sparge pipe.
It is preferred that the inner end cap is mounted on the upper outer of connecting tube, and is inlaid with the first filter screen in the middle part of inner end cap,
And the diameter of the first filter screen is equal to the internal diameter in upper end of connecting tube face, and inner end cap is to be threadedly coupled with connecting tube.
It is preferred that the outer end cap is threaded in the outside of inner end cap, and the inside of outer end cap is equipped with the second filter screen,
And the upper surface of outer end cap offers water jet, and the aperture of water jet is 2mm-10mm, at the same adjacent 2 water jets it
Between distance be 5cm-20cm.
It is preferred that the water inlet pipe is connected by booster pump with intake pipe, the grains of sand layer is with a thickness of 20cm-40cm.
Compared with prior art, the beneficial effects of the present invention are: the Sipunculus nudus high-density breeding pond；
