The production process is as follows: batching, bagging, sterilization, inoculation, spawning, mushroom management, and harvesting. The batching process is to make the culture medium in the mushroom sticks. The batching production process requires two-stage mixing. The first-stage mixing is to add and mix the raw material components. The second-stage mixing is to screen and mix the first-stage mixed raw materials conveyed by the auger. An inertial screen is set in the storage box. The raw materials conveyed by the auger fall on the inertial screen. Under the action of inertia and vibration, the raw materials are mixed, screened, and fall into the storage box. They are sent to the bagging machine production line through the auger conveying mechanism to make mushroom sticks.
[0003] The currently used two-stage mixing device has the following problems in use: since the raw materials are pre-wetted, the primary mixed material delivered by the auger conveying mechanism tends to accumulate in one place when falling on the inertial screen, resulting in low screening efficiency, and even failure to disperse screening and cause blockage. Therefore, the present application proposes a two-stage mixing device for mushroom stick raw materials. Utility Model Content

The screw belt is arranged between the rotating shaft and the screen slot. The screw belt is evenly fixed on the rotating shaft through the connecting rod. The screw belt swings through the power output of motor 1 connected to the controller.

[0018] The storage box 1 can store the mixed and screened raw materials, and transport them to the bagging production line through the auger conveying mechanism connected to the discharge port 12. The feed port 2 can be connected to the auger feeding mechanism to receive the primary mixed raw materials. The disperser 3 breaks up the falling raw materials to prevent the raw materials from falling and accumulating on the sieve plate 6 of the sieve slot 5.

The screw belt 32 swings through the forward and reverse output power of the motor 4 connected to the controller. When the motor 4 drives the rotating shaft 31 to swing, the falling raw materials contact the screw belt 32 and are scattered.
