Abstract

A fry screening device for aquaculture comprises a frame body, two bearing seats, a driving device and a pushing device, wherein the bottom of the frame body is connected with a drainage pipe; the twobearing seats are connected to the two sides of the top of the frame body respectively, and a screen is rotationally connected between the bearing seats on the two sides; the driving device is arranged between the frame body and the screen; and the pushing device is arranged on the frame body. Fry is screened through cooperative operation of the driving device, the pushing device and the screen,and therefore the effect of screening the fry is achieved; the pushing device is assisted to operate through a transmission device, the pushing device does not need to be manually operated to operate,and manpower is effectively saved; and when the fry screening device is operated, the screen can conduct comprehensive screening in the frame body, the screening effect is guaranteed, and the technical problems existing in above patents are effectively solved.

Description

technical field [0001] The invention relates to a screening device, in particular to a fish fry screening device for aquaculture. Background technique [0002] Fry is also called "fish flower". It is a juvenile fish that has just hatched, generally 6-9 mm in length. There are artificially bred fry and natural fish from rivers. When artificially cultivating fry, it is usually necessary to select fry of different sizes according to the size of the fry, and then separately raise the fry of different sizes. Avoid larger fry to eat small fry, causing small fry to die. [0003] After retrieval, the authorized patent publication number is CN109089993A, which discloses a fry screening device. A plurality of sieve plates are installed in the housing and the inside of the housing is separated to form an N-level screening pool. The sieve holes of the multiple sieve plates start from the first The first-level screening pool gradually decreases to the N-th pole screening pool, the wa...
