Description

A terminal discharging device for net cage throws material

Technical Field

The utility model relates to a fishery feeds and raises the device field, especially relates to a terminal discharging device that is used for the net cage to throw the material.

Background

As an important component part of fishery production in China, deep open sea cage culture plays an important role in promoting economic development of aquatic product industry in China, improving living standard of people and the like, but has the problems of high cost, low benefit and the like, so that the culture cost is very important to reduce. Feed is a modifiable cost in aquaculture, typically accounting for about 65% of aquaculture costs. Plays an important role in reducing the culture cost and perfecting the culture management. The operation of throwing material of deep water cage culture easily receives the influence of sea wind, can't throw the fodder to the box with a net center with a net accurately. The scattered feed particles can be scattered to the vicinity of the netting at the boundary of the net cage or even outside the aquaculture net cage under the action of wind waves. Because the fishes in the aquaculture net cage move in the net cage and are influenced by the netting, the fishes only forage in the central area of the net cage. Therefore, the feed is wasted, economic loss is brought, and meanwhile, some feed which is not utilized can be attached to the netting, and the culture environment is gradually polluted. And traditional box with a net throw material mainly rely on the manual work to empty the fodder at the box with a net marginal, and the fodder granule is carried the box with a net center gradually along with stormy waves. This feeding method is not only inefficient but also causes the problems described above.

In addition, aiming at the economic loss and the culture environment pollution caused by the current deep and open sea cage culture feed feeding, after relevant domestic patent papers are investigated and learned, the domestic existing cage feeding technology can be divided into mechanical arm type feeding and feeding gun type feeding. However, the mechanical arm type feeding (patent number: CN 202123128813.3) cannot work continuously, and after the work of one feeding point is finished, the material needs to be recharged to continue the next feeding operation. The feeding gun type feeding is mostly adopted in engineering, and can work only by a pneumatic system and a circular discharge port, but the circular discharge port is fixed on a feeding ship, and is too far away from a feeding point, so that the feed cannot be accurately thrown to the center of a net cage due to the influence of wind waves in the throwing process, and the feed is wasted. Therefore, the net cage feeding end discharging device which is not influenced by wind waves and can realize accurate feeding and has the function of freely adjusting the feed blanking point in order to conveniently feed is urgently needed.
