Description
Technical Field
The invention relates to a bayonet type fish separating machine.
Background
In the process of fish culture, because of the difference of the ingestion ability, the growth speed and the environmental adaptability of the fry, the individual difference of the cultured fish in the growth process is obvious. If no measures are taken to continuously breed fishes with larger individual differences together, the average growth speed of the fishes is obviously reduced, and the death rate of the slow-growing fish school is increased, thereby influencing the expected benefit of the culture. In addition, in the fish culture production link, in order to realize the culture or sale of fish with uniform specification, a large amount of manpower is needed to manually sort the adult fish with different specifications, so that the culture cost is greatly increased.
At present, a fish separating machine is generally adopted to separate fish shoals in large and small specifications, and the existing fish separating machine adopts rollers with different intervals to separate fish. For example, the chinese patent No. 2017202382029 discloses a roller-type fish separating machine, which uses a motor-driven rotating roller as power to drive fish to be conveyed from one end to the other end, and separates the fish through the size of an opening between two rotating rollers during the conveying process, and the fish drops down from the opening with a corresponding size. However, in the above roller-type fish separator, fish may be caught between the rotating rollers during the separation process, which may cause fish scaling or damage to the body surface of the fish.
