Description

Technical Field

[0001] The utility model relates to the technical field of feeding machines, in particular to a decentralized feeding machine for municipal garden fish feed. Background Art

[0002] In the municipal garden planning, in order to increase the aesthetics of the garden, ponds may be dug in the garden to increase the aesthetics of the garden. At the same time, in order to increase the ornamental value of the pond in the municipal garden, ornamental fish may be placed in the pond. In order to facilitate the feeding of the ornamental fish, feeding machines may be set up around the pond, and the feed is fed through the feeding machine, thereby facilitating the feeding of fish feed.

[0003] For example, the Chinese patent with publication number CN217038477U proposes a decentralized feeding device for aquaculture. The patent sets a feeding mechanism. After the material enters the feeding plate through the feeding hopper, it will fall into the inner cavity in the middle of the feeding plate. At this time, the second motor is controlled to rotate, and the second motor will drive the feeding hopper and the feeding plate to rotate at the same time. After the two rotate at the same time, the material inside the inner cavity will be sprayed from the position of the feeding port due to the action of centrifugal force, so as to achieve the purpose of decentralized feeding. However, in this scheme, it may be necessary to feed aquatic products such as fish and shrimps when they are artificially farmed, and then the usual feeding method may be to feed at the same position beside the aquaculture pool, which may limit the feeding range, and then the feeding range is too small and the feed may accumulate into clumps.

[0004] For example, the Chinese patent with publication number CN209572836U proposes a decentralized feeding device for aquaculture. The patent can perform decentralized and uniform feeding in all directions by setting dispersion rods and dispersion teeth, avoiding the uneven feeding caused by manual or semi-automatic machines, thereby avoiding the problem of different growth conditions of aquatic animals, and at the same time greatly reducing the labor of manual feeding, saving a lot of working time, and thus improving the work efficiency of aquaculture personnel. However, in this scheme, when aquatic products such as fish and shrimps are cultivated manually, it may be necessary to feed the aquatic products, and then the usual feeding method may be to feed at the same position beside the aquaculture pond, which may lead to a limited feeding range, and the feeding range is too small and the feed may accumulate into clumps.
