Description

Technical Field

[0001] The utility model relates to the technical field of aquaculture, in particular to a fish and grass placing device for rural aquaculture. Background Art

[0002] Fish and grass delivery devices for rural aquaculture play a number of important roles: In aquaculture, different fish species and growth stages require varying amounts of fish and grass. Fish and grass delivery devices can deliver fish and grass to pre-set quantities, avoiding the potential for overfeeding or underfeeding during manual feeding. In larger aquaculture ponds, fish distribution may be uneven across different areas. Fish and grass delivery devices can deliver fish and grass to specific locations, attracting fish to appropriate areas. This facilitates centralized management and observation of fish feeding and growth, and also facilitates subsequent fishing operations. Rural aquaculture fish and grass delivery devices help improve aquaculture efficiency, reduce costs, and protect water quality.

[0003] However, in the prior art, for example, China Publication No.: CN214709673U, "A fish and grass delivery device for rural aquaculture", this utility model discloses a fish and grass delivery device for rural aquaculture, which belongs to the field of aquaculture technology. A fish and grass delivery device for rural aquaculture, comprising a box body, a plurality of gear columns are fixedly fixed linearly and symmetrically at equal intervals on the upper and lower inner walls of the fixed frame, a half gear is provided in the middle of the fixed frame, a motor box B is fixedly provided on the left wall of the box body relative to the half gear, an electric motor is fixed inside the motor box B, a vertical groove is provided on the rear end of the top surface of the through cavity, a baffle B is provided inside the vertical groove, a plate groove is provided on the bottom surface of the through cavity relative to the baffle B, and a connecting rod is hinged on the front wall of the baffle B relative to the side groove. This utility model can achieve large-scale delivery of fish and grass, avoiding problems such as uneven feeding or eutrophication of water bodies in some areas caused by long-term delivery in one place.

[0004] However, this device does not have a swinging structure for the feeding port, so the fish grass cannot be thrown to a wider area. It is fixed in a very small range for release, and fish in different positions cannot have the opportunity to obtain the fish grass. As a result, the fish will over-gather and compete for the fish grass because they are concentrated in one place, so that the fish cannot feed relatively evenly in the entire aquaculture water area, which is not conducive to their growth and development. The device does not have a scraping and cleaning structure, so the fish grass may adhere to the inner wall of the release device. The remaining fish grass will accumulate more and more, gradually pile up, and eventually block the feeding channel, affecting the normal release of fish grass. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that the fish grass cannot be thrown into a wider area and is fixed in a very small range. Fish in different positions cannot have the opportunity to obtain the fish grass, which causes fish to excessively gather and compete for the fish grass because the fish grass is concentrated in one place, making it impossible for fish to feed relatively evenly in the entire aquaculture water area, which is not conducive to their growth and development. The fish grass may adhere to the inner wall of the delivery device, and the remaining fish grass will accumulate more and more, gradually pile up, and eventually block the feeding channel, affecting the normal delivery of the fish grass.
