[0002] A microbial inoculant refers to a live bacteria preparation that is processed from a fermentation broth adsorbed by a multi-controlled substance (such as peat and vermiculite) after the target organism (effective bacteria) is industrially propagated. It has the functions of degrading harmful substances, directly or indirectly improving soil, restoring soil fertility, preventing soil-borne diseases, and maintaining the balance of the rhizosphere microbial flora. When drying microbial inoculants, a drying device is needed for drying.

[0003] When the applicant applied for this invention, after retrieval, it was found that a Chinese patent disclosed a "solid-state fermentation drying device for microbial inoculants" with an application number of "202221799812.3". The patent mainly includes a housing, the bottom of the housing is an inverted conical structure, several support legs are fixedly installed on the outer periphery of the housing, a feed inlet is opened at the top of the housing, a discharge pipe with a stop valve is fixedly connected to the bottom of the housing, a vertical pipe is arranged inside the housing, the lower end of the vertical pipe is sealed, and the upper end of the vertical pipe penetrates through the housing and is rotatably connected to the housing, which can prevent material accumulation and has a higher drying efficiency. The exhaust device can discharge water vapor, further improving the drying efficiency.

[0004] Although the above patent can prevent the accumulation of microbial inoculants during drying, it can only dry the microbial inoculants once during the drying process, resulting in poor drying effect of the microbial inoculants and the need for secondary drying. Therefore, it is necessary to design a solid-state fermentation drying device for microbial inoculants. Summary of the Utility Model

[0026] The following further illustrates the present utility model in conjunction with the accompanying drawings and specific embodiments to help understand the content of the present utility model. The methods used in the present utility model are all conventional methods without special regulations; the raw materials and devices used are all conventional commercially available products without special regulations.

[0027] Referring to Figures 1-4 , a solid-state fermentation drying device for microbial inoculants provided by the present utility model includes a housing 1, a feeding trough 6 and an exhaust pipe 5 are fixedly connected to the upper end of the housing 1, support legs 2 are fixedly connected to the lower end of the housing 1, there are four support legs 2 and they are arranged in a circumferential array, a conveying mechanism 4 and a heating mechanism 3 are arranged inside the housing 1, and the heating mechanism 3 is located at the lower end inside the housing 1.

[0028] Specifically, the microbial inoculant to be dried is added into the interior of the housing 1 through the feeding tank 6. At this time, the heating mechanism 3 operates. Under the action of the heating mechanism 3, the microbial inoculant inside the housing 1 can be dried, and the water vapor generated by drying is discharged outwards through the exhaust pipe 5. During the drying process, the conveying mechanism 4 operates. The dried microbial inoculant at the bottom of the housing 1 is conveyed upwards by the conveying mechanism 4 and then falls down again. In this way, with the cooperation of the conveying mechanism 4, the microbial inoculant can be dried repeatedly, thereby improving the drying effect.

[0029] Specifically, the heating mechanism 3 includes a hot air blower 301, a connecting pipe 302, a shunt rack 303 and an air outlet nozzle 304. The lower end inside the housing 1 is fixedly connected with a shunt rack 303. The inside of the shunt rack 303 is hollow. The upper end of the shunt rack 303 is fixedly connected with an air outlet nozzle 304. The circumferential surface of the housing 1 is fixedly connected with a hot air blower 301. The air outlet end of the hot air blower 301 is fixedly connected with a connecting pipe 302. One end of the connecting pipe 302 away from the hot air blower 301 is fixedly connected with the shunt rack 303. When working, the hot air blower 301 operates, so that the generated hot air enters the inside of the connecting pipe 302, then enters the inside of the shunt rack 303 along the connecting pipe 302, and finally sprays outwards from the air outlet nozzle 304. In this way, the hot air can dry the microbial inoculant inside the housing 1.

[0030] The conveying mechanism 4 includes a motor 401, a conveying cylinder 402, a rotating shaft 403, a screw blade 404 and a support rod 405. The rotating shaft 403 is rotatably connected inside the housing 1. The circumferential surface of the rotating shaft 403 is fixedly connected with a screw blade 404. The upper end of the housing 1 is fixedly connected with a motor 401. The output end of the motor 401 is fixedly connected with the rotating shaft 403. The bottom end inside the housing 1 is fixedly connected with a support rod 405. The upper end of the support rod 405 is fixedly connected with a conveying cylinder 402. The screw blade 404 is located inside the conveying cylinder 402. When working, the motor 401 operates. At this time, under the action of the rotating shaft 403, the screw blade 404 can be driven to rotate. Under the action of the screw blade 404, the microbial inoculant at the bottom of the housing 1 can be conveyed upwards and then falls down from the upper end of the conveying pipe. In this way, the microbial inoculant can be dried repeatedly, thereby improving the drying effect.

[0031] Four reinforcing rods 9 are fixedly connected to the circumferential surface of the upper end of the conveying cylinder 402, and they are evenly distributed around the conveying cylinder 402. The reinforcing rods 9 are fixedly connected to the inner wall of the housing 1. When working, by arranging the reinforcing rods 9, the upper end of the conveying cylinder 402 can be reinforced under the action of the reinforcing rods 9, which is beneficial to the stable operation of the screw blade 404.

[0032] A first deflector 10 is fixedly connected to the circumferential surface of the conveying cylinder 402; a second deflector 11 is fixedly connected to the inner wall of the housing 1. During operation, by providing the first deflector 10 and the second deflector 11, and with the cooperation of the first deflector 10 and the second deflector 11, the microbial inoculum that falls can be dispersed, thus effectively preventing the microbial inoculum from accumulating together, and in this way, the drying efficiency can be improved.

[0033] Discharge pipes 7 are fixedly connected to both sides of the lower end of the housing 1, and valves 8 are installed on the discharge pipes 7. During operation, after the microbial inoculum is dried, the valve 8 is opened, and at this time, it is convenient for the microbial inoculum to be discharged outward from the discharge pipes 7.
