[0002] The processing of pesticide intermediate raw materials is an important link in the pesticide production process, and its quality is directly related to the performance and use effect of the final pesticide product. In the process of pesticide intermediate raw material processing, mixing, crushing and transportation are all indispensable. The traditional pesticide intermediate raw material processing process often uses a single mixing or crushing equipment, which cannot achieve continuous feeding and production, resulting in low production efficiency and easy to generate dust pollution. In addition, due to uneven material mixing or unsatisfactory crushing effect, it may also affect the quality and use effect of pesticide products. Therefore, in order to improve the production efficiency and product quality of pesticide intermediate raw material processing and reduce dust pollution, a variety of new processing processes and equipment have emerged in recent years. However, there are still some problems in the continuous mixing and crushing system, such as uneven material mixing and unstable crushing effect. Therefore, further research and improvement of pesticide intermediate raw material processing technology to improve its production efficiency and product quality is still an important issue to be solved in the current pesticide production field. Utility Model Content

A first main shaft is arranged in the premixing kettle, which passes through the top of the premixing kettle and is fixedly connected to the output shaft of the first motor. A stirring blade and a stirring arm are fixedly connected to the first main shaft.

[0006] Two crushing rollers are arranged in the crushing kettle, a screen is fixedly connected below the crushing roller, the screen is tilted, an auger is fixedly connected to one side of the crushing kettle through a pipeline, the screen is tilted toward the side where the auger is located, the pipeline on the top of the auger passes through the crushing kettle and extends to above the left crushing roller, the auger is fixedly connected to the output shaft of the second motor, and a partition is fixedly connected in the crushing kettle and is located above the right crushing roller.

[0007] A third motor is fixedly connected to the top of the mixing kettle. A second main shaft is arranged in the mixing kettle. The second main shaft passes through the top of the mixing kettle and is fixedly connected to the main shaft of the third motor. A frame-type stirring blade is fixedly connected to the second main shaft.

[0008] A fourth valve is fixedly connected to the bottom of the temporary storage kettle.

[0009] Furthermore, the bottoms of the premixing kettle, the crushing kettle, the mixing kettle and the temporary storage kettle are all downwardly concave structures.
