Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aquaculture equipment, and particularly to a rotatable disc for experimental teaching that can be disassembled and adjusted. Background Art
[0002] The clam seedling sowing machine is a key equipment in aquaculture, which is used to evenly sow clam seedlings into the water body to improve the breeding efficiency. However, clam seedlings are small in size, large in quantity and vulnerable to environmental influence. Traditional manual sowing has low efficiency and unevenness, which easily leads to the centralized accumulation of clam seedlings and an increase in mortality. The existing clam seedling sowing technologies mainly include handheld sowers and mechanized sowing machines. The handheld sower is easy to operate, but has low efficiency and high labor intensity in large-scale aquaculture. The mechanized sowing machine improves the efficiency, but its design and debugging are complex, and repeated experiments are required to verify the optimal sowing parameters and operation methods. In practical applications, due to the fragile vitality of clam seedlings, the risk of direct experiments in natural water bodies is high and the uncertainty is large. In addition, the natural environment is changeable, making it difficult to precisely control the experimental conditions. Therefore, it is particularly important to conduct simulation experiments in the laboratory environment. Through laboratory simulation experiments, the sowing process of clam seedlings can be studied under controllable conditions, reducing the experimental cost and improving the research efficiency.
[0003] Currently, there is a lack of experimental devices on the market that are specifically used to simulate the sowing process of clam seedling sowing machines. Such a device should be able to simulate the actual sowing process in the laboratory, precisely control the sowing parameters and conditions, and study the movement trajectories and distribution of clam seedlings under different conditions. Therefore, it is very necessary to develop a device of a rotatable disc for experimental teaching that can be disassembled and adjusted.
