And the outer blades 22 are located outside the inner blades 23, i.e. the spiral radius of the outer blades 22 is larger than the spiral radius of the inner blades 23. The above structure of the outer blades 22 and the inner blades 23 allows the agricultural wastes within the outer diameter range of the spiral of the outer blades 22 to be agitated during each rotation of the rotation shaft 21, so that a wide range of agricultural wastes in the agitation tank 101 are sufficiently agitated.

The included angle structure in the structure can reduce the area distributed to the outer blades 22 or the inner blades 23 by the rotating force of the rotating shaft 21, so that the outer blades 22 and the inner blades 23 are easier to drive to be inserted into agricultural wastes when the rotating shaft 21 rotates, and the agricultural wastes are pulled out to two sides; when the rotating shaft 21 drives the outer blades 22 and the inner blades 23 to rotate outwards from the agricultural waste, the two adjacent inner blades 23 and the two adjacent outer blades 23 can also form a dynamic state of gradually expanding from the interior of the agricultural waste to the exterior of the agricultural waste, and the agricultural waste can be pulled out to two sides and turned up to the end where the included angle is inserted. Therefore, the structure of the utility model can be conveniently inserted into the agricultural waste and then the agricultural waste is turned up, so as to realize stirring of the agricultural waste.

With continued reference to fig. 9, the outer blades 22 and the inner blades 23 on the same side of the radial reference plane of the rotating shaft 21 are arranged in a crossing manner, that is, two adjacent outer blades 22 and two adjacent inner blades 23 within the range of the outer blades 22 are respectively arranged at two ends of the rotating shaft 21 at an included angle between the two outer blades 22 and an included angle between the two inner blades 23. The structure can realize that after the two adjacent outer blades 22 are inserted into the agricultural waste and the agricultural waste is pulled out to two sides, the two adjacent inner blades 23 polymerize the turned agricultural waste, so that the stirring process of turning the agricultural waste from one side of the rotating shaft to the other side and repeatedly pulling out and gathering is formed, the agricultural waste is uniformly stirred, and the stirring structure has good effects on the mixing of sticky or cohesive powder particles and the mixing stirring of pasty agricultural waste added into the powder particles, so that the quality of finished products after processing is better.

Further, referring to fig. 8 again, two corresponding outer blades 22 on both sides of the radial reference surface of the rotating shaft 21 are disposed to intersect, and this arrangement makes the two corresponding outer blades 22 turn up the agricultural waste at the same time when the two outer blades 22 are inserted into the agricultural waste. The two corresponding inner blades 23 on the two sides of the radial reference surface of the rotating shaft 21 are also arranged in a crossed manner, and the structure is also capable of enabling the two corresponding inner blades 23 to simultaneously turn up the agricultural waste when the two corresponding inner blades 23 are inserted into the agricultural waste, and simultaneously enabling the two corresponding inner blades 23 to synchronously turn up the agricultural waste when the two inner blades 23 polymerize the agricultural waste. Therefore, the structure is beneficial to improving the efficiency of repeated stirring, thereby accelerating the discharging time of the finished product and improving the production efficiency.

Specifically, as shown in fig. 9, when two adjacent outer blades 22 rotate toward the inside of the agricultural waste to be inserted into the agricultural waste, the agricultural waste is pulled out to both sides and turned up along with the continued rotation of the rotating shaft 21. At the same time, the two inner blades 23 located inside the two outer blades 22 polymerize the turned-up agricultural waste, and the circulation thus forms a stirring process of repeatedly turning the agricultural waste from one side of the rotating shaft to the other side and repeatedly pulling the agricultural waste apart and gathering. Therefore, the stirring assembly 2 can continuously and uniformly stir the agricultural wastes in the stirring tank 101 during production, which is beneficial to uniformly heating the agricultural wastes in the stirring tank 101, thereby improving the fermentation efficiency.

In addition, with continued reference to fig. 1 and 2, the apparatus may further be provided with a ladder 6 and a screw conveyor 7, wherein a platform is arranged above the ladder 6 to facilitate the standing of staff and observe the working condition inside the stirring tank 1 from the discharge opening 102, or agricultural waste may be poured into the stirring tank 101 from the discharge opening 102 on the platform of the ladder 6, and a universal brake wheel is further arranged on the bottom surface of the ladder 6 to move and fix the ladder 6. The screw conveyor 7 is fixed on a moving frame 71, and universal brake wheels can be arranged at the bottom of the moving frame 71 to facilitate moving the screw conveyor 7. The below of screw conveyer 7 sets up feeder hopper 72, and the top of screw conveyer 7 sets up discharging pipe 73, moves screw conveyer 7 to discharging pipe 73 correspond on drain hole 102 during the use, pours the agricultural waste into feeder hopper 72 again, makes helical blade in screw conveyer 7 upwards carry the agricultural waste and follow discharging pipe 73 input to agitator tank 1 in, this material pouring mode is comparatively convenient and fast.
