Description

Technical Field

[0001] The utility model relates to the technical field of feed fermentation equipment, in particular to a fermentation equipment for microbial fermentation feed. Background Art

[0002] At present, in the process of microbial fermentation treatment of feed, due to the presence of liquid in the raw materials after fermentation, the fluidity of the raw materials becomes poor, and blockage is likely to occur during the collection process, which has a certain impact on the overall processing efficiency.

[0003] In recent years, with the continuous development of related technologies, the patent document with the application number 202222693538.8 that appears in the prior art discloses "This fermentation equipment for piglet feed production raw materials. When the piglet feed raw materials are fermented, the user controls the motor to drive the first bevel gear to rotate. The first bevel gear drives the rotating rod to rotate through the second bevel gear. The rotating rod drives the stirring blades to stir the feed raw materials inside the pig feed fermentation tank through the mounting block, so that it is in a dynamic fermentation state, thereby making the feed raw materials evenly heated in the pig feed fermentation tank, effectively improving the fermentation effect of the piglet feed raw materials. And when the user needs to discharge the fermented feed raw materials inside the pig feed fermentation tank, the user controls the electric push rod to drive the sealing plate and the baffle plate to move to the left, so that the baffle plate moves to the left side of the discharge pipe. At the same time, the user drives the screw rod to rotate through the turntable, and the screw rod drives the spiral blade to move downward into the discharge pipe. At this time, the rotating rod drives the spiral blade to rotate in the discharge pipe, so that the feed raw materials are continuously discharged", however, in the actual operation process, if the spiral blade structure and the stirring structure operate synchronously, it will increase the operation load of the power output device during the stirring process.
