Tail-end casting device for deep-sea cage culture pneumatic conveying feeding system

Abstract

The invention discloses a tail-end casting device for a deep-sea cage culture pneumatic conveying feeding system. The tail-end casting device comprises a rotary mechanism and a fixed floating mechanism. The rotary mechanism comprises a lower fixing pipe, a rotary connector, a lower rotary pipe and an upper rotary pipe; one end of the lower fixing pipe is connected with the tail end of a remote conveying pipeline of the culture pneumatic conveying feeding system, a flange plate is welded at the other end of the lower fixing pipe, and the rotary connector is arranged between the lower fixing pipe and the lower rotary pipe; the upper rotary pipe and the lower rotary pipe are hermetically connected with each other in a nested manner; the fixed floating mechanism comprises a vertical rod, a connecting flange plate, a buoy and a counter weight; the buoy is hermetically and fixedly connected with the vertical rod, and buoyancy can be generated, so that the integral tail-end casting device can float on a water surface; the counter weight is connected to the tail end of the vertical rod; the vertical rod is connected with the lower fixing pipe by the connecting flange plate. The tail-end casting device has the advantages that the tail-end casting device is simple in structure, low in manufacturing cost and suitable for casting feed to large cage groups, does not need to be driven by external motors and can continuously, automatically and efficiently rotate in casting procedures.

Description

technical field [0001] The invention relates to the field of farming machinery, in particular to a terminal feeding device used in an air feeding and feeding system for deep-sea net cage farming. Background technique [0002] The development of modern marine aquaculture is an important way to ensure food safety and meet people's demand for high-quality protein food. my country's ocean area is large, and there is huge room for the development of mariculture. With the rapid development of deep-sea cages in China, cage culture has expanded to deep waters below -15m, and the water body of a single cage culture has also further expanded, and cage culture has developed towards large-scale, deep-water and large-scale development. At present, feeding methods for deep-sea cage culture include artificial feeding and mechanical feeding, but artificial feeding is labor-intensive, uneven feeding, difficult to control the amount of feeding, and poor adaptability to the environment; mecha...

Problems solved by technology

At present, feeding methods for deep-sea cage culture include artificial feeding and mechanical feeding, but artificial feeding is labor-intensive, uneven feeding, difficult to control the amount of feeding, and poor adaptability to the environment; mechanical feeding mainly uses cages Breeding wind feed feeding system, the system generally includes fan, feeder, conveying pipe and terminal feeding device. The terminal feeding device currently used is a mechanical device driven by a motor to scatter pellet feed to the water surface. This device not only Energy-consuming, and the price is high, it is not suitable for the end of the feeding system of the deep-sea large-scale net cage group.
