Description

Technical Field

[0001] The utility model relates to a shrimp farming material spreading vehicle, belonging to the technical field of shrimp farming in aquaculture. Background Art

[0002] In aquaculture, there are two main ways of feeding feed: manual feeding and mechanical feeding. Manual feeding often involves using a small vehicle (such as a tricycle) to pull feed around the edge of the pond at regular intervals, and manually throwing the feed into the pond; mechanical feeding includes fixed-area feeding and mobile feeding on the water surface. Manual feeding is labor-intensive, the edge of the pond is often rugged and uneven, the road will be very muddy on rainy days, small vehicles are difficult to drive, and there is a safety hazard of overturning, and the amount of feed cannot be accurately controlled; mechanical fixed-area feeding cannot achieve uniform coverage of the breeding area, and is suitable for small-scale breeding; mobile feeding on the water surface covers a large area and disperses the feed, resulting in a large feeding amount.

[0003] CN 104823901A discloses an aquaculture feeder, comprising a feeding hopper, a conveyor belt is arranged at the lower part of the feeding hopper, a leakage hole is arranged on the conveyor belt, a regulating valve is arranged at the outlet of the bottom of the feeding hopper, and a cam is arranged between the upper belt and the lower belt of the conveyor belt. The aquaculture feeder uses the conveyor belt to transport food to a distant location, and the transport distance is long, but the spreading area only covers a narrow and long area, which belongs to mechanical fixed area feeding, and the feeding amount is large.

[0004] CN 220630699U discloses a feeding device for aquatic product breeding, comprising a bottom plate, a protective mechanism fixedly installed on the outer side of the bottom plate, a baffle fixedly installed on the top of the bottom plate, a material storage box fixedly installed on the top of the baffle, a feeding mechanism fixedly installed inside the bottom plate, a driving seat fixedly installed at the bottom of the bottom plate, and an auxiliary mechanism rotatably installed on one side of the driving seat. The feeding device belongs to a device for feeding on the water surface, with a large feeding coverage area, but a large feeding amount.

[0005] Shrimp farming is a special type of aquaculture with its own characteristics. First of all, shrimp farming has a very large demand for oxygen, so a large number of oxygen-enhancing equipment will be arranged in the farming waters. The oxygen-enhancing equipment will block the operation of the mobile feeding equipment on the water surface, so it is not suitable to use the mobile feeding equipment on the water surface to feed. Secondly, shrimps often go to the edge of the pond to forage in the morning, so it is best to feed the feed regularly and evenly along the edge of the pond. Thirdly, shrimp farming has high requirements for the quality of the water body. When the feed is insufficient, it will affect the growth of the shrimp. If it is overfed, the excess feed will be deposited and deteriorated at the bottom of the water, causing the water quality to deteriorate and causing a large number of shrimp deaths, so accurate feeding is very important. Summary of the invention

[0006] The utility model aims to provide a shrimp farming feeding vehicle which is suitable for walking and cruising on rugged or muddy pond foundations, has a large feeding capacity, accurate feeding, precise feeding amount, less feed waste, high efficiency and energy saving, is stable and durable, safe and reliable.
