[0002] Compound microbial fertilizer refers to a living microbial product composed of specific microorganisms and nutrients, which can provide, maintain or improve plant nutrition, increase agricultural product yields or improve the quality of agricultural products. With the continuous development of modern agricultural production technology, compound microbial fertilizer has become an important organic fertilizer. Compared with ordinary chemical fertilizers, compound microbial fertilizers are highly targeted, less polluting, and will not cause danger to human health. Therefore, the application of compound microbial fertilizers is becoming more and more extensive.

[0003] In the production and processing of compound microbial fertilizers, due to the need for fermentation by composite microorganisms, the fertilizer contains corresponding moisture, so it needs to be dried for subsequent storage and use. However, when using existing drying devices for drying, the drying efficiency is low due to the limited uniformity of the materials during drying. For this reason, the present application specifically proposes a compound microbial fertilizer drying device to solve the above problem. Utility Model Content

[0005] Each group of the material lifting devices comprises a material lifting rod fixedly connected to the longitudinal axis, and each of the material lifting rods is fixedly connected to a material lifting hopper which is in sliding contact with the inner wall of the drying cylinder.

[0006] Preferably, the lifting device includes a vertical rod fixedly connected to a discharge pipe, a horizontal plate fixedly connected to the lower end of the vertical rod, a lead screw rotatably connected to the opposite end of the horizontal plate and the discharge pipe, a connecting rod is arranged between the lead screw and the vertical rod, the connecting rod is fixedly connected to the valve plate, the lower end of the connecting rod is fixedly connected to a lifting rod, the left end of the lifting rod is fixedly connected to a sliding sleeve slidably matched with the vertical rod, the right end of the lifting rod is fixedly connected to a screw sleeve matched with the lead screw thread, and the horizontal plate is fixedly connected to a stepping motor for driving the lead screw.

[0009] When the present application is in use, the electric heating plate can heat the air in the drying cylinder, so that a high-temperature environment is formed in the drying cylinder to facilitate drying of the composite microbial fertilizer. An appropriate amount of the composite microbial fertilizer to be dried is placed in the drying cylinder through the feed pipe, and the drive motor is started to drive the longitudinal axis to rotate at a low speed, and then the lifting rod of the lifting device and the lifting hopper will also rotate synchronously with the longitudinal axis. During the rotation, the material hopper can scoop up the composite microorganisms at the bottom of the drying cylinder. As the lifting hopper rotates, the composite microbial fertilizer in the lifting hopper will spill downward. As the lifting hopper continues to rotate, the composite microbial fertilizer will be repeatedly spilled, and the spilled composite microbial fertilizer can fully contact with the high-temperature air in the drying cylinder, thereby quickly completing the drying, and the drying efficiency is high.
