Under the influence of its own gravity, the motor 34 moves down and drives the bottom closing cover 37 to contact the feed port 12. During the contact process, the sealing around the closing cover 37 is The sealing ring 39 seals the storage tank 1. During this process, the driving roller 36 at the bottom of the motor 34 approaches the working roller 21, and finally drives the bevel gear 391 at the bottom of the roller 36 to enter the annular tooth groove 393 at the top of the connecting seat 392 for meshing connection, so as to start the mixing component 2 to mix the raw materials. When the closing cover 37 is closed, the motor 34 is started to drive the bevel gear 391 at the bottom to rotate around its own axis. The bevel gear 391 moves and drives the receiving platform 394 at the bottom and the working roller 21 to rotate around their own axis.

During the movement of the moving plate 295, the trigger slope 296 will first contact the convex seat 15 on the inner wall of the storage tank 1. The contact surfaces of the moving plate 295 and the convex seat 15 are both provided with a trigger slope 296 that facilitates the sliding of the two. The straight-line distance between the trigger slope 296 and the working roller 21 gradually increases along its own movement direction. During the contact process, its convex seat 15 will continuously push the moving plate 295 close to the center of the storage tank 1. In this process, a certain pressure will be generated on the return spring 28 in the mounting cylinder 26, and the return spring 28 will be deformed. After the moving plate 295 is away from the convex seat 15, the connecting rod 294 will be driven by the elastic force of the return spring 28 Then it approaches the inner wall of the storage tank 1. During this process, the moving plate 295 and the connecting rod 294 keep moving synchronously, and the shovel plate 297 at the bottom of the moving plate 295 keeps moving synchronously with the moving plate 295, and stirs the raw materials at the bottom of the inner cavity of the storage tank 1 in the direction of material movement.

After the materials are mixed, the overall assembly is stopped, and the raw materials are placed in the storage tank 1 for long-term fermentation. After the fermentation is completed, the threaded cover 14 of the discharge port is opened, and the obtained straw fermentation bio-fertilizer is discharged from the discharge port 13 at the lower end of the storage tank 1 and dried. After drying, it can be made into granular straw fermentation bio-fertilizer through a granulator.
