Description

Technical Field

[0001] The utility model relates to the technical field of compound microbial fertilizer production, in particular to a granulating device for compound microbial fertilizer production. Background Art

[0002] Compound microbial fertilizer is a kind of biological organic fertilizer mixed with multiple organic fertilizers and microbial agents. It is a fertilizer made by adding microorganisms such as bacteria to the matrix. It adopts microbial engineering and fermentation technology to make the fertilizer more organic and nutrient-rich. At the same time, it has a good regulating and improving effect on the soil ecological environment. The product is divided into liquid, powder and granular types according to the dosage form. Granular fertilizer requires a granulating device to make the powdered raw materials into granules.

[0003] For example, a composite microbial fertilizer disc granulation device with publication number CN220238491U includes a workbench and a collection box, which effectively controls the flow rate of fertilizer delivery and improves the production quality of fertilizer, thereby making the quality of fertilizer produced by the granulation device more consistent, and effectively improving the speed of fertilizer granulation, saving labor costs, and ensuring the uniformity of fertilizer particle size;

[0004] The composite microbial fertilizer disc granulating device controls the flow rate of the fertilizer by cooperating with multiple structures such as an operating box, a turntable, a threaded rod and a sleeve, and then takes out the granular fertilizer by cutting. However, the amount of fertilizer entering is controlled manually, so the personnel need to pay attention to the changes of the fertilizer in the collection box at all times. If there is less fertilizer in the collection box and the personnel fail to find it in time, the granulation of the composite microbial fertilizer will be interrupted, thereby reducing the granulation efficiency. At the same time, the extruded fertilizer is cut off manually, and the cutting length is completely determined by the operator. It is impossible to ensure that the length of the composite microbial fertilizer particles is consistent, so the quality of the finished product is poor. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a granulating device for the production of a composite microbial fertilizer, which solves the problem that the existing composite microbial fertilizer disc granulating device requires personnel to always pay attention to changes in the fertilizer in the collecting box. If there is less fertilizer in the collecting box and the personnel fail to discover it in time, the composite microbial fertilizer granulation will be interrupted, thereby reducing the granulation efficiency. At the same time, the extruded fertilizer is cut manually, and the cutting length is completely determined by the operator, so the length of the composite microbial fertilizer particles cannot be guaranteed to be consistent, resulting in the problem of poor quality of the finished product.

[0011] Preferably, a second horizontal plate is fixedly connected to the middle of the right side of the shell, and a vertical rod is rotatably connected inside the second horizontal plate. A second bevel gear and fan blades are respectively fixedly connected to the upper and lower parts of the vertical rod, and the second bevel gear is meshingly connected to the first bevel gear.

[0012] Beneficial Effects

[0013] The utility model provides a granulating device for producing a composite microbial fertilizer, which has the following beneficial effects:
