[0002] Microbial fertilizers mainly use the life activities of certain microorganisms to enable crops to obtain specific fertilizer effects. In addition to containing a large number of beneficial microorganisms, microbial fertilizers also contain many other elements. General microbial fertilizers include inorganic substances, phosphorus, potassium, organic matter, and medium Elements, microbial bacteria, trace elements and other components. During the production of microbial fertilizers, the above-mentioned component materials are first formulated into raw materials according to specific proportions, and then the raw materials are stirred and mixed thoroughly, and then formed by granulation, drying, cooling and other procedures. Granular fertilizers, but in the prior art, the preparation of microbial fertilizer raw materials is mainly done manually, the labor intensity of workers is high and the production efficiency is low

[0003] Secondly, in the production process of microbial fertilizers, the semi-finished products formed after the raw materials are stirred and granulated need to enter the dryer for drying, and then be cooled. In the above process, dust floating objects will be generated. The dust is usually directly discharged after being treated by dust removal equipment, but in actual production, it is found that these dust floats contain a large amount of organic fertilizer and other floats, and these organic fertilizer floats are smaller in particle size and lighter in weight than other dusts , it is possible to recycle it

In addition, the cooling equipment in the prior art mainly adopts the combination of water cooling and air cooling, and its design structure is relatively complicated, the cost is high, and it is difficult to meet the requirements of mass continuous production

[0004] Furthermore, for microbial fertilizers, due to the high humidity of the semi-finished products, it is very easy to adhere to the inner wall of the dryer cylinder, causing problems such as material blockage, so it is necessary to equip the drying cylinder with a vibration device to make the material be separated by vibration. Cylinder wall, the current common vibration structure method is to install vibrating rods at equal intervals on the outer wall of the drying cylinder. It was found that due to the large volume and long length of the drying cylinder, and the vibrating rod head can only realize vibration stripping in a limited area around, the stripping effect needs to be improved. Therefore, in order to solve the above problems, there have been many Other forms of vibrating device structures, such as the above-mentioned patent with the authorized announcement number CN211012214U, which set a plurality of vibration motors outside the cylinder to achieve vibration stripping, but this method has a high cost, and another example is the Chinese patent with the authorized announcement number CN209524740U. The invention patent discloses a vibrating device for a composite microbial fertilizer dryer, which is provided with a number of hollow elbow covers on the wall of the dryer cylinder, and vibrating balls are arranged in the hollow elbow covers to adhere to the inner wall of the outer cylinder. The semi-finished material on the vibrator is separated by vibration, but this method is the same as the vibrating rod, which can only affect the vibration and separation of the material in the surrounding limited area.
