Description

A kind of oxygen-increasing chum dispenser head for preventing that aquatic seedling from wounding

Technical field

The utility model is related to technical field of aquaculture equipment, and more particularly to one kind prevents aquatic seedling from hitting The oxygen-increasing chum dispenser head of wound.

Background technology

Aquaculture is breeding, cultivation and the production activity of harvest aquatic animals and plants under manual control.It is commonly included in people The overall process of aquatic products is formed under work feeding management from seed.It broadly may also comprise Enhancement of fishery resources.Aquaculture has slightly The mode such as foster, intensive culture and high density culture.Extensive cultivation is that seed is delivered in medium and small natural water area, is supported completely by natural bait Into aquatic products, such as lake and reservoir is breeded fish and supports shellfish with shallow sea.Intensive culture is with bait throwing in, fertilizing method to form aquatic products in compared with small size pond Product, such as aqiuculrue, fish culture in net pen and enclosure culture, net enclosure culture.High density culture is using flowing water, temperature control, oxygenation and feeds high-quality bait Etc. method, high-density breeding is carried out in small size pond, so that high yield is obtained, such as Running Water Intensive Fish Farming, shrimp.

To improve the maximum return of aquaculture, only it is manually far from being enough, also be unable to do without aquaculture equipment Use, such as oxygen increasing equipment and feeder.

Oxygen increasing equipment is to increase the necessary equipment of water body dissolved oxygen, and its species is a lot, mainly has micro-pore aeration oxygenation, impeller to increase Oxygen machine, waterwheel aerator, inflatable aerator, jet aerator, water-spraying oxygen-increasing machine etc..Oxygen increasing equipment is mainly used for Increase the dissolved oxygen amount in water, by stirring water body, promoting to circulate above and below water body, reach oxygenation aeration and improve the effect of water quality, Oxygen increasing equipment can adhere to opening aerator more than 2 hours at fine day noon, run into overcast and rainy or change in weather, increasing be opened in time Oxygen machine.

Feeder has centrifugal feeder, wind spraying aid type feeder and falling type feeder with the form name that feeds intake；For The feeder that material mode is named has oscillatory type feeder, turnover plate type feeder, spiral feeder etc..Feeder will be according to difference The nutritional need of object is cultivated, the feed of comprehensive nutrition is fed, the shoddy feed that goes mouldy never is fed, the control of feedstuff feeding amount exists Eat up and be advisable in 2 hours, prevent the corrupt water quality of residual bait, the fish meal one fed in culture of Chinese mitten crab be to ensure that it is fresh, to prevent There is internal organ disease and polluted water.

Both the above equipment is the essential equipment of aquaculture field, then in the prior art, and feeder is with increasing Oxygen equipment is separated operation, will operate two hours, have the following disadvantages substantially：

1. power consumption is big, feeder and oxygen increasing equipment are power equipment, are operated two hours or so, daily power consumption compared with Greatly；

2. taking longer, separate operation, operating efficiency is influenceed, while prolonged noise and the vibrations to water, can also The rest of aquatic livestock is influenceed, and then influences its growing state, or even influences its survival rate；

3. the feed fed is the small particle of density, easily float on the surface so that aquatic livestock is difficult to feed, food profit It is low with rate.

4. installation cost is high, aerator is complicated.

If oxygen increasing equipment and feeder combination directly can be solved into problem above, but using existing discharge head often due to going out The violent solid particle therein of the material impetus may cause damage to aquatic seedling, or even dead, greatly reduce aquatic livestock Nursery stage survival rate.

Utility model content

The utility model provide a kind of oxygen-increasing chum dispenser head for preventing that aquatic seedling from wounding, with solve prior art due to The violent solid particle therein of the discharging impetus may cause the problem of damage is even dead to aquatic seedling.

To solve above-mentioned technical problem, the utility model uses following technical scheme：

A kind of oxygen-increasing chum dispenser head for preventing that aquatic seedling from wounding, is located at the discharging opening of oxygen-increasing chum dispenser, for by feed It is mixed in and is passed through in the air-flow at the bottom, includes the head body of column, the center of the head body is provided with axially disposed Gas-solid circulation road, the outside of head body gas-solid flow porch is provided with connection bump, and the head body has the hard of inside and outside socket Matter supporting layer and soft anticollision layer composition, the inside of the rigid support layer is inscribed on boss, the inscribed boss provided with ring-type Covered with unsaturated zone, the outside of the unsaturated zone is provided with cushion, and the cushion is located at the gas-solid flow exit of head body； Improved so that more soft outside head, reduced in head by the setting to head outside and internal structure The impact power with particle air-flow that portion comes out, so as to solve prior art because the violent solid particle therein of the discharging impetus can The problem of damage is even dead can be caused to aquatic seedling.

It is preferred that, the outer surface of the head body is provided with fin.

It is preferred that, the material of the rigid support layer is metal or vulcanie.

It is preferred that, the material of the soft anticollision layer is sponge.

It is preferred that, the unsaturated zone is the elastic sheet rubber of uniform some passages.

It is preferred that, the cushion is made up of the wire netting and gross porosity spongy layer of inside and outside setting.

Compared with prior art, the beneficial effects of the utility model are：The utility model passes through to outside head and interior The setting of portion's structure is improved so that more soft outside head, reduce inside head out with particle air-flow Power is impacted, so as to solve prior art because the violent solid particle therein of the discharging impetus may cause to damage to aquatic seedling The problem of wound is even dead.
