[0002] Feed refers to the main food for animals raised in modern fisheries and animal husbandry. Therefore, the quality of feed is crucial to the sustainable development of fisheries and animal husbandry. Feed is usually a mixture of raw materials of various particle sizes, including sea cucumbers, fish meal, soybean meal, grains, vitamins and minerals. When preparing feed, it is necessary to comprehensively consider the ratio of raw materials according to the animals being raised to ensure the quality and nutritional balance of the feed. In the process of preparing feed raw materials, due to the different shapes and sizes of raw materials, the processed raw materials are usually uneven in size, and the feed raw materials need to be screened. During the screening process, the existing feed screening machine is not easy to control the feed raw material feed amount, which will cause the raw materials to accumulate on the screen plate, which is easy to cause the screen plate to be blocked and affect the screening efficiency.
