Problems solved by technology

But this patent has the following problems: 1. Although this patent only needs to use one feeding device, the feeding device needs to move back and forth to different feeding points for feeding when in use, and each culture basket in the culture pond is relatively opposite to the culture pond. It is set statica...

Embodiment 1

[0038] Such as Figure 1~5 As shown, it is a preferred embodiment one of a crab breeding device of the present invention, which includes a breeding pond 1, a feeding device 2, a support 3, a slide rail 4, a sliding seat 5, a breeding box group, and a first driving member 8 and the second drive mechanism 9.

[0039] Wherein, one side of the culture pond 1 is provided with a water inlet, and the other side is provided with a water outlet, and the bottom surface of the culture pond is inclined downward from the side where the water inlet is located to the side where the water outlet is located.

[0040] There is only one feeder 2 and it is arranged on the side of the culture pond 1. The feeder 2 is provided with a feeder with a feed outlet 20. The structure of the feeder 2 can be designed with reference to the prior art. Of course, manual feeding can also be used to feed at the feeding device.

[0041] The above-mentioned support 3 spans on the culture pond 1; the slide rail 4 ...

Embodiment 2

[0050] Such as Figure 6-9 As shown, it is the second preferred embodiment of a crab cultivation device of the present invention, the crab cultivation device is basically the same as the first embodiment, the difference is that in this embodiment, each culture box group can move up and down relative to the culture tank and is arranged on the rotating shaft 78 superior. Concretely, include the third driving mechanism 6 that is arranged on the rotating shaft 78 and is connected with the transmission of the breeding box group to drive each breeding box group to move up and down, the third driving mechanism 6 includes the third motor 61 that is arranged on the rotating shaft 78 and Lead screw nut pair, the screw mandrel 62 in the screw mandrel nut pair is arranged vertically and is connected with the output shaft of the 3rd motor 61, and the nut 63 in the screw mandrel nut pair links to each other with the breeding box group. Furthermore, the third motor 61 can drive the screw ma...

Abstract

A crab breeding device comprises breeding box sets, connecting mechanisms, a first driving piece and a feeding device. Each feeding box set comprises a body (77) and at least two breeding boxes (7) arranged at intervals along the periphery of the body, each breeding box (7) is provided with a feeding port (70), and the feeding ports (70) of the breeding boxes (7) are aligned one by one in the circumferential direction; the connecting mechanisms are used for connecting the breeding box sets and are suspended on a culture pond (1); the power output end of the first driving piece (8) is connected with the breeding box sets and used for driving the breeding box sets to rotate; and the feeding device (2) is arranged on the culture pond (1) and comprises a feeding part, and the feeding part can be in one-to-one correspondence with the feeding port (70) of any one of the breeding boxes in the state that the breeding boxes (7) rotate in the circumferential direction, so that feeding of each breeding box (7) is completed. Compared with the prior art, the crab breeding device has the beneficial effects that feeding can be completed only by arranging one feeding point, and water flowing can be promoted.

Description

technical field [0001] The invention belongs to the technical field of aquaculture devices, and in particular relates to a crab cultivation device. Background technique [0002] The main breeding mode of crabs is pond farming. Although the total amount is large, there are problems such as backward pond facilities, low breeding survival rate, and low added value of products, which restrict the development of the industry. Land-based monomer culture of crabs is one of the feasible methods to solve the above problems. By collecting sub-adult crabs from ponds and transferring them to separate cultures in the monomer culture system, it can not only prevent fratricide and go on the market in reverse seasons, but also produce high-quality crabs such as soft shell crabs. Value-added aquatic products. [0003] Based on this, people have developed a land-based monomer culture device for crabs, such as the patent No. ZL201110280120.8 for the invention patent "Indoor Stereo Cultivation...
