[0002] Feed is a general term for food for raised animals. In a narrower sense, feed mainly refers to food for animals raised in agriculture or animal husbandry. Feed includes more than ten varieties of feed raw materials such as soybeans, soybean meal, corn, fish meal, amino acids, miscellaneous meal, whey powder, oils, meat and bone meal, grains, and feed additives.

[0003] At present, more and more livestock are being raised. With the progress of society, the artificial breeding industry has developed greatly, and the demand for breeding is increasing. The process of feed production includes raw material cleaning, crushing or grinding, mixing, granulation, drying and packaging. In the feed production process, it is necessary to add a variety of raw materials to the mixing equipment according to the proportion, and then use the stirring mechanism in the mixing equipment to mix the various raw materials. The raw materials used in the preparation of different types of feed are not exactly the same, which requires cleaning the mixing equipment when changing the processed feed, and cleaning the raw materials attached to the inner wall of the mixing equipment.

[0004] However, the existing mixing equipment does not have a cleaning function and cannot automatically clean its inner wall. The inner wall can only be cleaned by staff after the mixing operation is completed. Due to the complex internal shape of the mixing equipment and the many material accumulation positions, manual cleaning is time-consuming and labor-intensive, and the work efficiency is low. In addition, the stirring mechanism structure in the above-mentioned existing mixing equipment is relatively simple, and the stirring range is limited. It is impossible to fully and efficiently stir the materials in the mixing equipment, which affects the quality of the finished feed and has low work efficiency. Utility Model Content

[0033] Working principle:

[0034] After a variety of raw materials are poured into the batching tank 4, the rotating drive member 6 is started, driving the second stirring shaft 2-5 installed on its output shaft to rotate, and then driving the second stirring wheel 2-6 installed thereon to rotate, so as to stir the materials in the central area of ​​the batching tank 4; since the adapter frame 2-7 is fixedly connected to the second stirring shaft 2-5, and the auxiliary stirring mechanism is installed on the adapter frame 2-7, when the second stirring shaft 2-5 rotates, it can drive the auxiliary stirring mechanism to revolve around the second stirring shaft 2-5. At the same time, under the action of the transmission mechanism, the rotating second stirring shaft 2-5 can drive the first stirring shaft 2-4 in the auxiliary stirring mechanism to revolve and rotate at the same time, thereby increasing the range of action of the stirring device 2, so that the stirring device 2 can efficiently and fully stir the various raw materials in the batching tank 4;

[0035] Since the annular mounting tube 3-7 in the cleaning device 3 is connected to the adapter frame 2-7, the rotating second stirring shaft 2-5 can drive the cleaning device 3 to rotate, thereby driving the multiple groups of second scraper blades 3-4 and the multiple groups of first scraper blades 3-3 in the cleaning device 3 to revolve around the second stirring shaft 2-5. The revolving multiple groups of second scraper blades 3-4 and the multiple groups of first scraper blades 3-3 can scrape off the materials adhered to the inner wall of the batching tank 4, so as to avoid the materials adhering to the inner wall of the batching tank 4 for a long time and making it inconvenient to clean them later; in addition, the rotating cleaning device 3 can also achieve the purpose of stirring the materials in the batching tank 4;

[0036] After completing the batching operation and completely discharging the material in the batching tank 4, a cleaning liquid (clean water can be used) is introduced into the water spray structure 5. The water spray nozzle 5-4 in the water spray structure 5 can spray the cleaning liquid onto the inner wall of the batching tank 4. At the same time, the rotating drive part 6 is started to drive the cleaning device 3 to rotate. In conjunction with the cleaning liquid sprayed from the water spray nozzle 5-4, the interior of the batching tank 4 can be thoroughly cleaned to avoid residual material on the inner wall of the batching tank 4 and affect the subsequent batching process.
