[0036] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0037] Example 1: Figure 1-8 A bait delivery device for a multi-layer shrimp cage, wherein the multi-layer shrimp cage is composed of four stacked shrimp cages, including a feed pipe 8, a feed tray 18, a feed pipe support and a flushing pipe 16; a filler is used at the bottom of the feed tray to block the gap at the upper end of the feed pipe.

[0038] There are 4 material pipes, all of which are installed on the support, and the lower ends of the 4 material pipes extend into the 4 shrimp cages respectively;

[0039] The upper end of the feed pipe is connected to the bottom of the feed tray; the bait in the feed tray can enter the shrimp cage through the feed pipe;

[0040] A flushing pipe is arranged above the unloading tray, and a water valve is arranged on the flushing pipe.

[0041] The pipe openings at the upper ends of the material pipes are evenly arranged at the bottom of the material tray, specifically in a circle and equally divided in the circumferential direction.

[0042] The supporting member is a plug pipe 2 which is inserted into the 4-layer shrimp cage in a through manner, and the 4 material pipes are all arranged in the plug pipe.

[0043] A feeding hopper 7 is provided on the feeding tray to facilitate the bait to enter the feeding pipe smoothly.

[0044] The bottom of the shrimp cage is provided with a water-permeable material receiving piece, which is a gauze with an edge and a stainless steel substrate.

[0045] A feeding funnel 17 is provided above the unloading tray, for example, fixed on a bracket.

[0046] How to operate:

[0047] When feeding, first close the flushing pipe and add the bait into the feeding funnel. The bait enters the feeding tray at the bottom of the hopper through the feeding funnel, and finally enters the receiving dishes of the four shrimp cages through the feeding pipe. After 5 minutes of feeding, open the flushing pipe and use the impact of water to flush down the bait adhering to the inner wall of the feeding pipe to prevent the feeding pipe from being blocked, so that the feed can be smoothly and reliably delivered to the shrimp cage. Moreover, since the receiving dish is made of gauze, water can pass through it, but the bait will not be washed away by water. This is one of the important originality of this solution. The flushing can be stopped after a few minutes of flushing.

[0048] An aquaculture module matched with the feeding device includes an insert pipe 2 and four shrimp cages 3 for culturing shrimps and crabs (up to 20 layers or even more);

[0049] The shrimp cage is a hollow shrimp cage, 4 shrimp cages are stacked, and a socket 32 ​​is provided on the bottom plate of the shrimp cage; a plurality of shrimp cages can be connected in series by inserting a pipe through the socket;

[0050] The lower end of the insertion tube is provided with a limiting piece for preventing the shrimp cage from slipping out of the bottom of the insertion tube; the limiting piece is a limiting ring 14.

[0051] There are 4 feed pipes 8 for feeding feed in the insertion pipe, and 4 feed pipe openings are arranged on the pipe wall of the insertion pipe; the lower ends of the 4 feed pipes extend into the 4 shrimp cages respectively through the 4 feed pipe openings.

[0052] A feed receiving member 31 is provided in the shrimp cage, and the feed is deposited on the feed receiving member after coming out of the feed pipe, so that the shrimp can eat it easily.

[0053] like Figure 2-3 ,5-6, an aquaculture device, comprising a water tank 1 and a plurality of aquaculture modules arranged in the water tank; the aquaculture modules are the aforementioned aquaculture modules;

[0054] 24 aquaculture modules are used, and the 24 aquaculture modules are arranged in an array; specifically, they are arranged in 4 rows and 6 columns;

[0055] A support plate 5 is provided at the bottom of the water tank; the aquaculture module is placed on the support plate; there is a gap between the support plate and the bottom plate of the water tank, and the gap serves as a sewage discharge area 11; an aeration mechanism is provided in the sewage area, specifically an aeration pipe or an aeration disk.

[0056] It also includes a cover plate 4 with a cover plate opening 41; the cover plate opening is used for the upper end of the cannula to pass through, and the cover plate is used to press down the uppermost shrimp cage in the aquaculture module to prevent the shrimp from escaping.

[0057] A drain pipe 12 is provided at the bottom of the water tank. Alternatively, the drain pipe may not be provided, and the water in the water tank may be pumped away by a pump. The tail water is purified by an additional water treatment device and discharged directly or reused after treatment.

[0058] The bottom of the water tank is provided with a pipe inserting seat 6 for positioning the bottom of the pipe inserting. Under the joint action of the pipe inserting seat and the cover plate, the breeding module will not move horizontally and vertically.

[0059] The aquaculture device is arranged on the support in two layers.

[0060] Working principle description: First, put water in the water tank, put the shrimp 9 into the shrimp cage, and put one shrimp in each shrimp cage. Then put the culture module with the shrimp on the tray of the water tank in 4 rows and 8 columns. The bottom of the plug is inserted into the plug seat, and then the top of the culture module is sealed with a cover. If necessary, fasten the cover with a lock, or press a heavy object on the cover to limit the culture module. Then open the water inlet pipe and the drain pipe, adjust them to the appropriate opening, and realize the microcirculation of water in the water tank. If sewage needs to be discharged, open the drain pipe completely, or use a sewage pump to extract water from the sewage collection area at the bottom of the water tank.

[0061] During the breeding process, turn on the aeration device to ensure the dissolved oxygen index in the water.

[0062] When feeding, feed (granular feed) is put into the hopper manually or with an additional feeding device, and it can be fed 3-5 times a day.
