[0002] Feed is the general term for the food of farmed animals. More narrowly, feed generally mainly refers to the food of animals farmed in agriculture or animal husbandry. Feed includes more than a dozen varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, grease, meat and bone meal, grains, and feed additives.
[0003] At present, there are more and more livestock farms. With the progress of society, the artificial breeding industry has developed greatly, and the demand for feed is increasing. The feed production process includes raw material cleaning, crushing or grinding, mixing, granulation, drying, and packaging. In the production and processing process, due to the different nutritional requirements of different farmed animals, additives are added to the feed for some animals. Additives are in liquid or powder form, and it is a difficult problem in the mixing process to evenly mix them into the feed. Liquid materials often need to be atomized before being added to the mixture, and then through mixing and stirring, the additives are adsorbed onto the feed raw materials, so as to achieve the purpose of adding additives. This process is realized by using an additive atomizing device for feed processing. In terms of structure, the traditional additive atomizing device adopts a setting with a nozzle above and a stirrer below.
[0004] However, it is found in the use process that the traditional additive atomizing device has certain defects: First, with the direct atomizing and spraying setting, the excess solution during spraying cannot be reused, increasing the production cost; in addition, the above-mentioned stirring mechanism is relatively simple and cannot stir down the feed attached to the inner wall of the container, increasing the cleaning frequency of the device and also increasing the labor intensity of the staff. Therefore, there is an urgent need to design an additive atomizing and adding device for feed processing to solve the above problems. Summary of the Utility Model

[0036] Working principle:
[0037] When in use, open the ball valve installed on the liquid delivery pipeline. The additive flowing out from the liquid source flows into the annular liquid inlet pipe 19-3 in the atomizing spraying assembly 19 through the liquid inlet pipe, and is sprayed onto the materials in the tank structure in the form of mist through multiple groups of atomizing nozzles 19-2. At the same time, the stirring motor 20-1 starts to drive the hollow rotating shaft 1 to rotate, and then drives the upper stirring and scraping wall assembly 2 and the lower stirring and scraping wall assembly 3 to rotate synchronously. Among them, the rotation of the upper mounting arm 2-6 can drive the upper scraping blade 2-8 and the upper stirring shaft 2-2 mounted thereon to revolve. The revolving upper scraping blade 2-8 can clean the inner wall of the mixing tank 14 in the tank structure. At the same time, driven by the upper driven sprocket 2-4, the upper driving sprocket 2-5 and the chain, the upper stirring shaft 2-2 can rotate while revolving, so as to efficiently stir the materials in the upper and middle parts of the tank structure. Similarly, the rotation of the lower mounting arm 3-5 can drive the lower scraping rod 3-6 and the lower stirring shaft 3-2 mounted thereon to revolve. The revolution of the lower scraping rod 3-6 can drive the lower scraping plate 3-7 mounted thereon to clean the inner wall of the tank bottom shell 5. At the same time, driven by the lower driven sprocket 3-3, the lower driving sprocket 3-4 and the chain, the lower stirring shaft 3-2 can rotate while revolving, so as to efficiently stir the materials at the bottom of the tank structure, so that the materials can be fully mixed with the additive.
[0038] During the actual working process, the additive flowing to the bottom of the tank structure flows into the liquid tank 11 under the action of the started first pump body 9, and the impurities are filtered out by the filter screen 10 arranged in the liquid tank 11. The started second pump body 12 can pump the filtered liquid flowing into the liquid tank 11 into the liquid inlet pipe 13, and flows into the atomizing spraying assembly 19 through the liquid inlet pipe 13 to participate in the feed production process again, avoiding the waste of additives and saving the production cost.
[0039] After the stirring and mixing operation is completed, start the linear drive cylinder 4-5 in the opening and closing valve assembly 4. The piston rod of the linear drive cylinder 4-5 retracts, driving the lifting pull rod 4-3 mounted thereon to move upward, and then driving the sealing shell 4-2 mounted at the lower end of the lifting pull rod 4-3 to move upward along the hollow rotating shaft 1, thus opening the discharge port 7 to facilitate the outflow of materials from the discharge port 7 and realizing the discharging operation. During the discharging process, driven by the linear drive cylinder 4-5, the reciprocating lifting movement of the sealing shell 4-2 can disturb the materials, and can avoid the blockage of the discharge port 7 by the materials, which affects the discharging process.
