Problems solved by technology

[0003] The existing feed feeding machine adopts the method of throwing and spraying directly into the sea, and the throwing amount is relatively large. On the one hand, the waste of feed is serious, and on the other hand, it is easy to cause local eutrophication of the water body.
Someone has proposed an underwater feeding device, but this underwater feeding device has a complex structure and is not suitable for large-scale application
[0004] Moreover, due to the various activities of the cultured animals and the existence of humus, the water body is turbid, which not only affects the observation of the breeding situation by the farmers and makes timely treatment, but also affects the respiration of the cultured animals.

Embodiment 1

[0027] As shown in 1 and 5, the marine aquaculture equipment equipped with a feed recovery cylinder,

[0028] It includes a cylindrical breeding box 1 for breeding, and the bottom of the breeding box 1 is separated by a partition 6 with a feed recovery cylinder 7;

[0029] It also includes a distributing mechanism 4 for feeding feed, the top of the distributing mechanism 4 is connected to the mixing box 2 through the transmission pipe 201, and the upper part of the mixing box 2 is connected to the feeding hopper 202;

[0030] One side in the feed recovery cylinder 7 is connected with a water delivery pump 5, and the other side is connected with a collection pipe 9, and the collection pipe 9 is connected with a liquid suction pump 901, and the feed recovery cylinder 7 at the bottom of the breeding box 1 is used for breeding. Immediately ingested feed is recycled to avoid waste of feed, eutrophication of water body, humus, etc., and improve the transparency of water body to faci...

Embodiment 2

[0034] The further optimization scheme of this embodiment on the basis of embodiment 1 is as follows: Figure 2-4 As shown, a stirring mechanism 3 is horizontally arranged in the stirring box 2, and the stirring mechanism 3 includes a motor 301 connected to the outside of the stirring box 2. The rotating shaft 302 of the motor 301 is connected to the stirring box 2 horizontally, and the front and rear ends of the rotating shaft 302 are connected with limited positions. Block 305, slip ring 303 is movably connected on the rotating shaft 302 between the limiting blocks 305, slip ring 3 slips on the rotating shaft 302 and is limited by the limiting block 305 to slip in a certain area during the feed stirring process. Stirring the feed once can increase the compactness of the feed, reduce the hydrolysis rate of the feed, and delay the dissolution rate of the feed in the water after it is put into the water body, which is beneficial to the collection of the feed.

Embodiment 3

[0039] When the mariculture equipment provided with the feed recovery cylinder of the present invention is actually used, the feed is put into the feed hopper 202, and the feed reaches the distribution mechanism after being processed by the stirring box 2, and the feeding speed of the feed is controlled by controlling the rotational speed of the runner 401 and the amount of input, the cultured animals in the breeding box 1 can ingest the feed when the feed sinks into the bottom of the breeding box 1 case, and the activity of the cultured animals in the breeding box 1 is improved, which is beneficial to improving the survival rate of the cultured animals and improving the meat quality. The feed recovery cylinder 7 at the bottom of the breeding box 1 recycles the feed that is not ingested by the cultured animals immediately during the breeding process to avoid waste of feed, eutrophication of the water body, humus, etc., improve the transparency of the water body to facilitate obs...

Abstract

The invention discloses a marine culture device equipped with a feed recovery drum. The marine culture device comprises a cylindrical culture box used for culturing, wherein the bottom part of the interior of the culture box is separated into the feed recovery drum through a partition plate; the marine culture device also comprises a feed distribution mechanism used for feeding a feed; a stirringbox is connected with and arranged above the feed distribution mechanism through a conveying pipe; the upper part of the stirring box is connected with a feeding hopper; one side of the interior of the feed recovery drum is connected with a water conveying pump; and the other side of the interior of the feed recovery drum is connected with a collection pipe which is connected with a liquid suctionpump. The marine culture device provided by the invention can effectively solve the death of a cultured animal due to turbidity of a culture water body, effectively improves the survival rate of thecultured animal, and can realize controllable feeding and recycling of the feed.

Description

technical field [0001] The invention belongs to the field of aquaculture equipment, and in particular relates to a seawater aquaculture equipment provided with a feed recovery cylinder. Background technique [0002] The objects of mariculture are mainly fish, shrimps and crabs, shellfish, algae and other economic animals such as sea cucumbers. Mariculture is an important part of the aquaculture industry. It focuses on the development of certain fish, shrimp, shellfish and echinoderms (such as sea cucumbers) with high economic value. The production cycle is short and the output per unit area is high. [0003] The existing feed feeding machine adopts the method of throwing and sprinkling directly into the sea, and the amount of throwing is relatively large. On the one hand, the waste of feed is serious, and on the other hand, it is easy to cause local eutrophication of the water body. Someone has proposed a kind of underwater feeding device, but this underwater feeding device...
