Ascending and descending net box flexible material barrel for safe baiting feeding

Abstract

The invention provides an ascending and descending net box flexible material barrel for safe baiting feeding. The ascending and descending net box flexible material barrel for safe baiting feeding consists of waterproof canvas, a material barrel conveying rope, a material barrel lifting rope, a barrel opening collecting rope, a barrel bottom lacing line, a heavy bob and a nylon ring, and is characterized in that a high-intensity polyethylene single-wire rope is used for manufacturing the barrel opening collecting rope, the barrel bottom lacing line, the material barrel lifting rope, the material barrel conveying rope and the heavy bob rope ring, concrete is used for casting a heavy bob, the rope ring is preburied in the heavy bob, the arc length of the outwards exposed rest part is 9cm, the midpoint of the outwards exposed rope ring is connected with the midpoint of the barrel bottom lacing line, the double-layer waterproof canvas is adopted for processing the flexible material barrel with the diameter being 50cm and the height being 70cm, the barrel opening of the flexible material barrel is provided with the barrel opening collecting rope, the barrel bottom of the flexible material barrel is provided with the barrel bottom lacing line, the material barrel lifting rope is arranged on the barrel opening collecting rope, the nylon ring is arranged on the barrel bottom lacing line, the upper end point of the material barrel conveying rope is connected with the nylon ring, the lower end point of the material barrel conveying rope is connected with the midpoint of the material barrel lifting rope, and the midpoint of the barrel bottom lacing line is hung and connected with the cylindrical concrete heavy bob.

Description

technical field [0001] The invention relates to the technical field of lifting net cage bait throwing appliances. Background technique [0002] Lifting net cage is a modern cage culture facility, which has the advantage of avoiding disasters such as red tide or typhoon. When the surface water temperature of seawater is too high or too low, the buoyancy of the cage system can be reduced by adjusting the lifting balance system of the lifting net cage until the net cage sinks to the required middle and bottom waters, so that the cage cultured fish are exposed to wind and waves Or middle and bottom waters with relatively stable water temperature. Feeding technology of lifting net cages is related to the safety of bait delivery, bait utilization coefficient and breeding effect, and it is one of the key factors for the success or failure of lifting cage farming. When the lifting type net cage sinks to the required depth, how to put the bait into the net cage box body without was...

Problems solved by technology

When the lifting net cage sinks to the required depth, how to put the bait into the cage without waste is a technical problem that has not been solved by the existing lifting net cage baiting technology

In the existing lift-type net cage culture production, when the net cage sinks to the required depth, the farmer uses a plastic bucket as the bait feeding bucket, and pours the bait in the plastic bucket directly into the bait feeding channel sewn with net clothes. When the bait settles from top to bottom in the bait feeding channel, it will drift with the water flow to the surrounding sea area of ​​the lifting net cage, resulting in waste of bait and sediment pollution of residual bait on the seabed, affecting the full acquisition of bait and normal growth of farmed fish development, which not only loses bait but also brings sediment pollution to the marine environment

If the lifting net cage is raised to the water surface only for feeding, it will waste a lot of manpower and financial resources, and affect the normal growth and development of farmed fish; especially when disasters such as red tide or typhoon come, the sea surface water temperature is suddenly too high or too low At this time, it is dangerous and unrealistic to raise the lifting cage to the water surface for baiting, and loses the meaning of the lifting cage to avoid risks
