Description

Crab farming device

technical field

The utility model relates to the technical field of aquaculture, in particular to a crab breeding device.

Background technique

Artificial breeding of crabs has very high requirements on the farms. At present, the ponds for cultivating crabs generally require an area of 1-5 mu. Crab ponds have sufficient water sources, good water quality, and easy access to water. The water depth is generally 1-1.5 meters. . The best quality of the bottom of the crab pond is sandy loam and gravel soil, with good ventilation performance, which is conducive to the growth and reproduction of aquatic plants, benthic animals and plants, and can provide natural feed for river crabs. The thickness of the mud at the bottom of the pond is generally not more than 5 cm. Anti-escape facilities, such as brick walls and plastic films, should be built around the crab pond. The water inlet and outlet of the crab pond should be blocked with barbed wire to prevent river crabs from escaping.

In the prior art, ponds for artificially cultivating crabs have too high requirements on the natural environment, and it is not easy to find suitable farms. According to the living habits of crabs, crabs like to be on the edge of the pond ridge, and crabs are aggressive and food-competitive. Crabs in ordinary ponds are fed unevenly with bait, and crabs compete for food with each other, which is not conducive to the growth of crabs. .

Utility model content

The purpose of the utility model is to provide a crab breeding device to solve the problem of uneven bait feeding in existing crab breeding ponds.

The technical problem to be solved by the utility model adopts the following technical solutions to realize:

The crab breeding device includes a plurality of cornerstones, each cornerstone is provided with a waterproof case, a motor and its controller are installed in the case, a feeding disc is installed above the case, and a feeding dial is arranged in the feeding disc. Rod, the said feeding rod is installed on the central shaft, and the said central shaft is connected with the motor; the said feeding rod is installed horizontally in the feeding disc; there are multiple feeding discs at the bottom hole; a feeding hopper is arranged above the center of the feeding disc, and the outlet of the feeding hopper is located above the feeding disc;

An arc-shaped simulated ridge slope is connected between the adjacent cornerstones.

There is a discharge impeller in the discharge port.

A conical platform is also installed on the central axis, and the conical platform is located below the discharge port of the feeding hopper.

The crab breeding device provided by the utility model simulates the ridge slope of a natural fish pond, provides sufficient habitat for crabs, and sets a plurality of feeding discs at the same time, and puts bait along the simulated ridge slope to adapt to the living habits of crabs , and the bait is automatically fed, the bait is evenly fed, and the efficiency is high, which prevents crabs from competing for food.

detailed description

The specific implementation of the utility model is described in conjunction with the examples.

Example 1

As shown in Figure 1, the crab breeding device includes a plurality of cornerstones 11, and the cornerstones 11 are arranged in the pond according to the situation of the breeding pond, and each cornerstone 11 is provided with a waterproof cabinet 10, and a motor 9 and its controller are installed in the cabinet 10 , the top of the cabinet 10 is equipped with a feeding disc 4, and the feeding disc 4 is provided with a rod 5, and the rod 5 is installed on the central shaft 8, and the central shaft 8 is connected to the The motor 9 is connected; the feeding rod 5 is horizontally installed in the feeding disc 4; the bottom of the feeding disc 4 has a plurality of feeding holes 6; the center position of the feeding disc 4 is provided with a feeding Hopper 1, the outlet 2 of the feeding hopper 1 is located above the feeding disc 4; feed is placed in the feeding hopper 1, and it is put into the feeding disc 4 from the feeding outlet 2, and the rod 5 rotates under the drive of the central shaft 8, The material in the center of the feeding disc 4 is evenly distributed into the entire feeding disc 4 and falls from the feeding hole 6 .

Between the adjacent foundation stones 11 are connected arc-shaped simulated ridge slopes 12 . The simulated ridge slope 12 simulates the slope of the natural environment, provides sufficient habitat for crabs, and is located under the feeding disc 4 to avoid competition among crabs for food.

There is a discharge impeller 3 in the discharge port 2 . Blowing impeller 3 can control feed throwing excess and throwing rate.

A conical platform 7 is also installed on the central axis 8 , and the conical platform 7 is located below the discharge port 2 of the feeding hopper 1 . The conical platform 7 prevents the feed from accumulating in the center.
