The market demand for bio-organic fertilizers, particularly in the organic and green agriculture sectors, is enormous. Bio-organic fertilizers are a type of fertilizer made by combining specialized functional microorganisms with harmlessly treated and composted organic materials, primarily derived from animal and plant residues, such as livestock and poultry manure and crop straw. Bio-organic fertilizers, with their high organic matter content, can improve soil quality, enhance soil physical and chemical properties, enhance soil water and fertilizer retention, and reduce soil compaction caused by long-term use of chemical fertilizers. The beneficial microorganisms in bio-organic fertilizers form a symbiotic relationship with soil microorganisms upon entry, inhibiting the growth of harmful bacteria and converting them into beneficial ones. The interaction and mutual promotion create a synergistic effect. In the production process of bio-organic fertilizers, the raw materials are typically processed before being uniformly mixed. However, existing mixing devices typically add all the raw materials at once before stirring and mixing, resulting in poor mixing uniformity and low mixing efficiency. Therefore, it is necessary to develop a bio-organic fertilizer raw material mixing device that can evenly mix the raw materials and improve the raw material mixing efficiency. Utility Model Content

A spiral stirring paddle is rotatably connected in the mixing box, and the spiral stirring paddle is driven by a third motor fixedly connected to the top of the mixing box. The lower end of the spiral stirring paddle extends into the discharge pipe at the bottom of the mixing box.

[0021] The working process of this embodiment is as follows:

[0022] When producing biological organic fertilizer, first add the microbial agent required for production into the agent box 3, add water into the water tank 7, and then add raw materials such as plant straw and animal feces into the crushing box 1 through the feeding port. Synchronously start the first motor to run, the first motor drives one of the crushing rollers to rotate, and drives the two crushing rollers to rotate relative to each other under the action of gear meshing. Synchronously start the star-shaped discharge valve 4 to run, and the microbial agent begins to discharge through the discharge pipe. The incoming raw materials are gathered between the crushing roller group 2 under the action of the guide plate 15 for crushing. At the same time, the microbial agent is preliminarily mixed with the raw materials. After that, the raw materials enter the double screw conveyor 5, and the second motor is started. The machine 6 drives the double screw conveyor 5 to run, and at the same time, the conveying pump 14 is started and the regulating valve is set. Water enters the water spray pipe 8 and is sprayed from the nozzle 9 and falls into the double screw conveyor 5. The double screw conveyor 5 can further evenly mix the raw materials while conveying the materials. The mixed materials enter the mixing box 10, and the third motor 13 is started to run. The third motor 13 drives the spiral stirring paddle 11 to rotate, and at the same time, the rod stirring paddle 12 is driven to rotate under the action of the belt and the pulley, so that the biological organic fertilizer raw materials can be fully stirred. At the same time, the spiral stirring paddle 11 can send the stirred material out from the discharge port, avoiding the material from being blocked at the discharge port.
