Abstract
The utility model relates to a fish egg hatching device, which is an improvement based on the original device. The device is a barrel shape body, the bottom part is provided with a water inlet pipe, a gauze cover is arranged at the upper part barrel mouth, and the barrel mouth is equipped with a water outlet pipe. The utility model is characterized in that a slow flow device is arranged above the water inlet pipe, the slow flow device is a shuttle shape body, and is fixed and connected on the inner wall of the barrel, and a plurality of holes are arranged on the connector of the slow flow device. The utility model is suitable for the fish egg hatching, in particular the hatching of thin egg membrane fish eggs, and can improve the fish egg hatching rate greatly.
Description
Technical field
The utility model relates to the hatch fish roe device
Technical background
Hatch fish roe is in main at present circuit, hatching pail, the hatching cylinder mode that grows up at four large Chinese carp fish-egg characteristics that adopt of China.Fish-egg is placed in the hatching pail, and, there is water inlet pipe at the bucket end, and delivery port is arranged at hatching pail top, by the water inlet of water inlet pipe and the draining of delivery port, water constantly flowed in bucket.This mode proves the effect of row in the hatching of many fishes.But the fish-egg that is unable to undergo water impact for some egg membranes adopts aforesaid way to hatch, and will cause following two kinds of results: (1) incubation rate is low; (2) availability of incubator descends.In addition, some utilize cement pit and bucket to be equipped with the method that aerator carries out hatch fish roe, cause the problem of hypoxia death in the hatch fish roe process owing to can't solve the accumulation of thin roe membrane fish-egg, thereby can not adapt to the hatching of thin roe membrane fish-egg.Because traditional hatching pail is to adopt directly water inlet, for making full use of the dischargeable capacity of hatching pail, often can only be by strengthening inflow by the water inlet pipe of hatching pail bottom, because the bore of water inlet pipe is fixing narrow and small, adding big yield causes flow velocity to increase undoubtedly, increased water flow will cause because the excessive egg membrane that causes of water flow velocity breaks for the thin fish ovum of egg membrane the impulsive force of fish-egg.Although can effectively prevent thin fish-egg egg membrane splintering problem if adopt minimizing discharge to solve the water flow velocity problems of too, but the availability of the dischargeable capacity of hatching pail is then little by discharge, can cause following two kinds of situations to take place: (1) can cause fish-egg to be piled up by the hatching that the intrinsic hatching fish-egg of hatching pail number carries out the thin roe membrane fish-egg, and the death of fish-egg takes place; (2) to guarantee that the hatching that approaches fish-egg survives, then will reduce the fish-egg amount that drops into.
Technology contents
The utility model improves on the basis of former hatching pail, has designed a unhurried current device.The unhurried current device is fixedly mounted on the top of water inlet pipe, the unhurried current device is a fusiformis body, two upper and lower vertical fixing of capitate body of fusiformis body are connected on the fixed head, fixed head coincide and is fixedly connected on the staving inwall, have a plurality of holes on the edge of fixed head, the gross area at hole is 2-3 a times of water inlet area.
Now be described further in conjunction with the accompanying drawings
Fig. 1 is the hatching pail structural representation
1---staving 2---gauze lid 3---unhurried current device 4---water inlet pipe
5---fixed head 6---hole 7---delivery ports
The utility model is a barrel-shaped body, water inlet pipe 4 is arranged at staving 1 bottom, gauze lid 2 is arranged on the bung of staving 1, the bung edge is provided with delivery port 7, on water inlet pipe 4, be provided with unhurried current device 3, the unhurried current device is an one fusiformis body, and the unhurried current device is by on the fixed head 5 identical staving inwalls that are fixedly connected on above the water inlet pipe.Have a plurality of holes 6 on the edge of fixed head 5.
The utility model is such realization, the water that starts water inlet pipe by the current that design is pulled, allow water enter hatching pail, the fish-egg of hatching is put into hatching pail, disperse from the fusiformis body on the water slug fixed head of water inlet pipe, water enters hatching pail from the hole, after water in the hatching pail has been expired, water flows out from delivery port, because water is mobile, fish-egg stirs up and down in hatching pail, because bung has the gauze lid, fish-egg can be because of current flow away, and the unhurried current device is the fusiformis body, two capitate bodies on the two sides of fixed head at the capitate body of the central part bottom of fixed head above water inlet pipe, make aqueous dispersion, and can reduce the impulsive force of water, top capitate body overcomes the accumulation of fish-egg effectively and hypoxia death improves the dead rate of incubating.
The utility model is applicable to hatch fish roe, the hatching of especially thin fish-egg.
Unhurried current device experiment result
Hatching pail 0.4m
3(effectively water body)
Supply water: the self-priming clarified water pump of IZDB35 type that dynamo-electric joint stock company limited produces supplies water to adopt Guangdong to reach the clouds
To carry out the result as follows with the hatching pail that does not install the unhurried current device additional installing additional respectively in test:
| The hatching pail that does not have the unhurried current device | Unhurried current device hatching pail is arranged |
| Batch fish-egg serviceability rate fish-egg number | Batch fish-egg serviceability rate fish-egg number |
| 1 0% 300,000 | 1 100% 350,000 |
| 2 0% 260,000 | 2 100% 370,000 |
| 3 0% 190,000 | 3 100% 320,000 |
It is all broken in 30 minutes after ovum is gone into bucket not have unhurried current device bucket
After having unhurried current device bucket ovum to go into bucket, the egg membrane fragmentation that causes because of mechanical damage does not appear
