Description
Technical field
A kind of slot is the utility model is related to, more particularly to a kind of postlarva slot.
Background technology
General fishery is both needed to screen the fry before fry cultivation is carried out, and the fry of different sizes is separated
Cultivation, the situation of small fish and the mutual food that disaccords is robbed to avoid occurring big fish, while the fry of different sizes can also inhaled
The stage of growth due nutrition is received, the effect of reaching fry stabilized growth whereby.
Traditional fry screening is typically screened using the string bag to the species of fry, but such a method is to the sieve of fry
Select efficiency more beneath, and fry contacts friction with the string bag and easily causes fry dead, and certain warp is brought to fry culturist
Ji loss.
Utility model content
The utility model provides a kind of postlarva slot, and the fry screening that can efficiently solve system typically uses the string bag pair
The species of fry is screened, but such a method is more beneath to the screening efficiency of fry, and fry contacts friction with the string bag
The defects of easily causing fry death.
In order to solve the above-mentioned technical problem, the utility model provides a kind of postlarva slot, including screening bucket and base, institute
The top for stating screening bucket is provided with top cover, and the top of the top cover is connected by one end of the first L-type connecting tube and tracheae, the gas
The other end of pipe and the air inlet of vavuum pump connect, and the apical lateral of the screening bucket is uniformly provided with several the first valves,
The port of export of first valve with screen pipe one end be connected, it is described screen bucket bottom with being fixedly connected at the top of base,
Floss hole is provided with the middle part of the junction of the screening bucket and base, the floss hole is connected with one end of the second L-type connecting tube, institute
State the other end and the interspersed connection of screening bucket bucket wall, the second L-type connecting tube and the junction of screening bucket of the second L-type connecting tube
Second valve is installed.
As a kind of optimal technical scheme of the present utility model, the top cover is fixed by the top of screw and screening bucket to be connected
Connect, and the junction of top cover and screening bucket is provided with seal washer.
As a kind of optimal technical scheme of the present utility model, the diameter of the screening pipe is less than the diameter of tracheae, described
It is that transparent plastics material is made to screen bucket, base, tracheae and screening pipe.
The beneficial effect that the utility model is reached is：This kind of postlarva slot, it is simple in construction, it will be screened by vavuum pump
Bucket is evacuated, and multiple personnel hold one end of more screening pipes, just can be rapidly completed the screening operation of same fry, due to
It is that transparent plastics material is made to screen bucket, base, tracheae and screening pipe so that personnel, can the moment when being screened to fry
The situation of fry screening is observed, improves the survival rate of fry after screening really.
Brief description of the drawings
Accompanying drawing is used for providing further understanding to of the present utility model, and a part for constitution instruction, with this practicality
New embodiment is used to explain the utility model together, does not form to limitation of the present utility model.In the accompanying drawings：
Fig. 1 is structural representation of the present utility model；
In figure：1st, bucket is screened；2nd, base；3rd, vavuum pump；4th, tracheae；5th, the first L-type connecting tube；6th, top cover；7th, the first valve
Door；8th, screening pipe；9th, the second valve；10th, the second L-type connecting tube；11st, floss hole.
Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in figure 1, a kind of postlarva slot of the utility model, including screening bucket 1 and base 2, the top of screening bucket 1 are set
There is top cover 6, the top of top cover 6 is connected by the first L-type connecting tube 5 with one end of tracheae 4, the other end and the vavuum pump 3 of tracheae 4
Air inlet connection, screening bucket 1 apical lateral several the first valves 7, the port of export and sieve of the first valve 7 are uniformly installed
One end of pipe 8 is selected to connect, the bottom of screening bucket 1 is fixedly connected with the top of base 2, the junction middle part of screening bucket 1 and base 2
Provided with floss hole 11, floss hole 11 is connected with one end of the second L-type connecting tube 10, the other end and sieve of the second L-type connecting tube 10
The interspersed connection of 1 barrel of wall of bucket is selected, the second L-type connecting tube 10 and the junction of screening bucket 1 are provided with the second valve 9.
Further, top cover 6 is fixedly connected by screw with screening the top of bucket 1, and the connection of top cover 6 and screening bucket 1
Place is provided with seal washer, improves the air-tightness of screening bucket 1.
Further, the diameter for screening pipe 8 is less than the diameter of tracheae 4, and screening bucket 1, base 2, tracheae 4 and screening pipe 8 are equal
