Description

Technical Field

[0001] The utility model relates to the technical field of crab seedling breeding, in particular to a device for timing broadcasting feed in water for crab seedling breeding. Background Art

[0002] After the crab seedlings enter the pond, they are immediately fed with crushed tofu and powdered egg yolk, which are evenly spread on the water surface and the waterside slopes. The daily amount is about 3% to 5% of the crab seedlings' weight. The first two days are mainly plant-based baits, and after 3 days, fish paste, bone meal, wheat flour, etc. are added. The principle is to feed enough food with a little left over. After 5 to 7 days, they will molt and become first-stage juvenile crabs. At this time, the juvenile crabs are light yellow, fresh and tender. Thereafter, they change from planktonic to benthic life, and the bait changes from paste to paste. The first-stage juvenile crabs' food intake increases, and the amount of bait is increased to about 6% to 10% of the crab's body weight.

[0003] Crab seedlings are mostly fed by artificial spreading of feed into the pond to cultivate young crabs, or by mechanical spreading over long distances.

[0004] After searching, in the prior art, announcement number CN202111087109.X discloses a feed spreading device for freshwater fish farming. The utility model is mainly used for spreading feed in breeding ponds. It has simple operation, high degree of automation, uniform feed spreading, wide spreading range, saves time and effort at work, and is more efficient.

[0005] However, the device and the prior art still have the following defects:

[0006] The existing feed spreading device cannot spread the feed on a regular basis and over a large area, so people need to check on the lake all the time. At the same time, the existing feed spreading device does not have the feed storage effect, and feed needs to be added slowly, which causes the overall cultivation to consume a lot of time and energy. Utility Model Content

[0007] The utility model aims to provide a device for regularly spreading crab seedling feed in water for crab breeding, which can spread crab seedling feed in a large range and regularly.

[0019] Furthermore, the placement rack includes a plug-in column inside, and a support pad for increasing the force-bearing area is fixedly connected to the outside of the plug-in column.

[0020] By adopting the above technical solution, the support pad increases the contact area between the whole and the bottom of the pond, making it convenient to install the whole in the middle of the pond, thereby facilitating the feed spraying of the whole.

[0022] 1. The rotating mechanism and feed placement box are used to ensure that the whole can rotate when spreading feed, so that the whole can be spread over a large area.
