[0002] Feed is a general term for food for animals raised by humans. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten types of feed raw materials, such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oil, meat and bone meal, grains, feed additives, etc. Since feed contains many types, it is necessary to stir and mix the feed during feed production.

[0003] In the process of feed production, stirring equipment is needed to perform mixing and stirring operations. Among them, the stirring tank is one type of stirring equipment. The existing traditional stirring tank has a relatively simple structure, mainly including a tank body equipped with multiple sets of legs, and a simple stirring component is arranged in the tank body to stir the material in the tank body.

[0004] However, in the actual working process, it is found that when the existing mixing tank is used, the items to be mixed need to be lifted and moved to the entrance of the mixing tank, and then the items to be mixed are poured into the interior of the mixing tank. Since the tank body of the mixing tank is relatively high, during the loading operation, the workers need to climb the ladder, which will consume a lot of physical strength of the workers, the labor intensity is high, and there are great safety hazards, which makes the workers easy to get injured. In addition, the above-mentioned traditional mixing tank has a single stirring method when stirring the materials, the stirring speed of the materials is slow, and the materials cannot be fully stirred, resulting in poor stirring effect.
