They are processed from biomass, animal and plant waste, and plant residues, eliminating toxic and harmful substances. They are rich in beneficial substances and can not only provide comprehensive nutrition for crops, but also have long-lasting fertilizer effects. They can increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of the soil. They are the main nutrient for green food production, and therefore, organic fertilizers are being used more and more widely.

[0010] Compared with the prior art, the embodiments of the present application have the following beneficial effects:

[0011] The output end of the motor drives the driving gear to rotate the driven gear, and the rotation of the driven gear drives the rotating tube and the spiral blade to rotate. The rotation of the spiral blade has the ability to evenly transport materials, so that the organic fertilizer moves to the right in the cooling cylinder. The water inlet pipe is connected to the water pump. When the water pump works, water is flushed into the first inner cavity and the water flow channel, and the water is discharged through the water outlet pipe.
