Feed premixing machine

Abstract

The invention discloses a feed premixing machine. The feed premixing machine comprises a mixing container, a rotating shaft which is arranged in the mixing container and a mixing propeller which is arranged on the rotating shaft. The stirring paddle comprises an a stirring paddle and a b stirring paddle, a shoveling and scraping knife which is arranged at the bottom of the a stirring paddle, stirring blades are arranged on the stirring paddle, and a shoveling and scraping knife is arranged on the end portion of the b stirring paddle. A horizontal included angle which is arranged between the stirring blades and the stirring paddle is 20 to 40 degrees, and the scrapping face of the shoveling and scraping knife which is arranged on the end portion of the b stirring paddle matches with the periphery wall of the mixing container. Due to the fact that the rotating shaft is provided with the a stirring paddle and the b stirring paddle and the scrapper knife is arranged at the lower end of the a scrapper knife, the feed premixing machine can be used for scrapping materials which are located at the bottom of a scrapping container. Due to the fact that the scrapper knife is arranged on the end portion of the b stirring paddle and the end portion of the b stirring paddle is close to the inner periphery face of the container, the feed premixing machine can be used for shoveling and scrapping materials on the inner periphery face of the scrapping container. Therefore, the feed premixing machine ensures that the materials are not stuck to the wall face of the container in the process of mixing the materials.

Description

technical field [0001] The invention relates to the field of feed production, in particular to mixing equipment before feed raw materials enter the production line. Background technique [0002] In feed production, the raw materials used include powder, liquid, and paste materials. If these three forms of materials are directly put into the production line, not only can they not be mixed evenly, which will affect the quality of the feed, but also these materials will Adhesion to the inner wall of the equipment will either block the pipeline of the equipment or paste the sieve, resulting in shutdown and production stoppage. Therefore, the general practice is to mix the powder, liquid and paste materials evenly before the materials enter the production line. At present, there is no special equipment for premixing these materials, and most of them are mixed by concrete mixing machines. For example, a concrete open mixer is used for mixing. Since the stirring paddle of this ...

AI Technical Summary

Problems solved by technology

For example, a concrete open mixer is used for mixing. Since the stirring paddle of this mixer is only a rod-shaped object, a scraper is provided at its lower end (scraping the material at the bottom of the container), so this equipment can only carry out Horizontal mixing, instead of turning up and down, there is still the problem of uneven mixing of materials. At the same time, this equipment does not have a scraping device, so the phenomenon of material sticking to the wall is serious
