At least one group of crushing blade racks 44 is fixedly connected to the outer surface of the propeller shaft 42, so that the fertilizer product pushed upward can be crushed by at least one group of crushing blade racks 44, thereby improving the dispersion of the subsequent fertilizer turning.

[0048] A dispersion component 45 is disposed at the top of the material guide cylinder 41, and a circulation component 46 for circulating and spraying the liquid material at the bottom of the fermentation tank 1 upward is disposed at the bottom of the material guide cylinder 41;

[0049] By setting the dispersion component 45, the fertilizer guided upward by the material guide cylinder 41 can be evenly dispersed to the upper layer. By setting the circulation component 46, the liquid material at the bottom of the fermentation tank 1 can be circulated and sprayed upward to achieve a layer of fertilizer and a layer of liquid material, further enhancing the balance of fertilizer turning, thereby improving the subsequent fertilizer fermentation effect, and solving the problem that the fermentation equipment in the prior art can usually only guide the fertilizer at the bottom of the fermentation tank 1 upward, and cannot guide the liquid material settled below alone, affecting the balance of fertilizer fermentation.

[0050] Refer to the attached Figure 3 , Figure 4 and Figure 6 The motor 43 is fixed to the top of the fermentation tank 1, and the output shaft of the motor 43 is fixedly connected to the top of the propeller blade shaft 42, and the outer surface of the bottom end of the guide cylinder 41 is provided with a plurality of inlets;

[0062] By energizing the electromagnet 469, the electromagnet 469 generates an adsorption force, which can adsorb the T-shaped metal rod 467, so that the T-shaped metal rod 467 moves upward, and the two ratchet blocks 468 are separated, so that the fermentation product can be turned over separately, which has a good selective transmission function;

The pipeline layout of the ventilation mechanism 5 is fully utilized, which further improves the energy-saving life of the fermentation equipment and solves the problem that the existing fermentation equipment is not easy to clean after the fermentation work is completed, so that in the long run, the fermentation area of ​​the fermentation equipment is easily damaged, thereby affecting the service life of the fermentation equipment.

[0069] The exhaust pipe 54 is provided to discharge gases such as carbon dioxide inside the fermentation tank 1, thereby improving the fertilizer fermentation effect.

[0070] Embodiment 2: Based on embodiment 1, the difference is that;

[0071] Refer to the attached Fig. 9 The bottom end of the branch pipe 55 is open, and the inside of the bottom end of the branch pipe 55 is fixedly connected to an elastic contraction rod 552 through a support rod, and the contraction end of the elastic contraction rod 552 is fixedly connected to a conical piston block 553, and the conical piston block 553 is used to seal and block the opening at the bottom end of the branch pipe 55. A booster pump 52 is installed at one of the ports of the three-way pipe 53;

The conical piston block 553 is provided to seal and block the open part of the bottom end of the branch pipe 55, so as to prevent the gas or liquid medium inside the branch pipe 55 from being directly discharged through the open part during gas or water injection, thereby affecting the uniformity of gas or water injection.
