[0002] The composite microbial fertilizer matrix crushing and screening device is a key equipment in modern agricultural fertilizer preparation technology. Its design and application are aimed at solving the challenges of low efficiency, uneven product quality and protection of microbial activity encountered in the traditional microbial fertilizer production process. With the popularization of agricultural sustainable development and green agriculture concepts, composite microbial fertilizers have gradually received attention due to their significant advantages in improving soil fertility, promoting crop growth and reducing the use of chemical fertilizers. However, the production process of composite microbial fertilizers, especially the crushing and screening of the matrix, has extremely high performance requirements for the equipment. Composite microbial fertilizers usually contain organic matter (such as livestock and poultry manure, crop residues, etc.), inorganic matter and specific microbial strains. These components need to be crushed before mixing to reduce the particle size and ensure that the microorganisms can be evenly distributed, while improving the physical properties of the fertilizer. The screening process is used to remove large particles and impurities to ensure the uniformity and applicability of the fertilizer.
[0003] At present, most of the composite microbial fertilizer matrix crushing and screening devices on the market need to achieve high precision in the screening system to ensure the uniformity and applicability of the fertilizer, but the screen is also prone to clogging, especially when dealing with sticky or wet raw materials, which will reduce the screening efficiency and increase the difficulty of maintenance. At the same time, it is impossible to screen different particle sizes at the same time. Therefore, we proposed a composite microbial fertilizer matrix crushing and screening device.

At the same time, vibration can prevent the sieve holes from being blocked, reduce the frequency of manual maintenance, and improve the continuous operation capacity of the device.
[0024] like Figures 1 to 3As shown, the main mechanism 2 includes a main shell 201, four collecting frames 202 are arranged at the bottom of the main shell 201, a fixing plate 203 is fixedly connected to the main shell 201, the four collecting frames 202 are respectively located below the third sieve plate 110, the second sieve plate 108 and the first sieve plate 106, three baffles 112 are respectively located between the four collecting frames 202, the top of the fixing plate 203 is fixedly connected to the bottom of the motor 101, the pulley 102 is rotatably connected to the main shell 201, the screening frame 105 is slidably connected to the inner wall of the main shell 201, and the pulley 102 is located above the fixing plate 203.
