[0002] Organic fertilizers contain a variety of organic acids, peptides, and rich nutrients including nitrogen, phosphorus, and potassium. They can not only provide comprehensive nutrition for crops, but also have a long fertilizer effect. They can increase and renew soil organic matter, promote microbial reproduction, and improve the physical and chemical properties and biological activity of the soil. They are the main nutrients for green food production. As the level of agricultural modernization increases, organic food is increasingly valued by people. Ecological agriculture is also valued. Organic fertilizers will gradually replace other fertilizers and become an essential fertilizer for crop growth. Therefore, the equipment for the production and processing of organic fertilizers has become a top priority.

[0003] The existing organic fertilizer extrusion granulation devices all concentrate and pile up the materials, and then extrude and granulate them through the granulation port, but the extrusion efficiency is low and the forming effect is not ideal.

The rounded organic fertilizer is discharged through the guide disc and finally enters the drying device for drying to become a finished product. The roller bin arranged in the extrusion device functions to make the first roller and the second roller replaceable. The purpose of replacement is that the specifications of the hemispherical grooves on the outer surfaces of the rollers are different, so that organic fertilizer particles of different sizes can be pressed according to production requirements.

[0028] Working principle: When in use, various organic fertilizers are introduced into the interior of the mixing bin 103 through the feed window 101, and the organic fertilizers are fully mixed by the mixing device in the mixing bin 103, and then the mixed organic fertilizers are preliminarily dried by the primary drying bin 102, and the dried organic fertilizers are transported to the crushing bin 201 by the first conveyor belt 104 for crushing, and then the organic fertilizers are transported to the transfer bin 203 by the second conveyor belt 202, and the organic fertilizers in the transfer bin 203 are transported to the material basket 301 by the first auger conveyor 204, and then the organic fertilizers are introduced into the first pressing roller 311 and the second pressing roller 312 through the material basket 301.

[0029] The main motor 308 is started to rotate the first pressing roller 311 and the second pressing roller 312 to extrude the organic fertilizer. The preliminarily formed organic fertilizer is introduced into the third conveyor belt 401 through the discharge guide groove 304 and enters the scattering box 402. The stirring rod 406 in the scattering box 402 is used to scatter the mutually adhering parts of the organic fertilizer. The scattered organic fertilizer enters the screening machine 403 to screen out the crushed materials. The crushed materials are discharged from the crushing guide groove 407 installed at the lower end of the screening machine 403. The formed organic fertilizer enters the first collecting bin 404 and is transported to the abrasive disc 501 for grinding through the second conveying auger 405.

[0030] The hydraulic telescopic rod 508 is adjusted to change the inclination angles of the grinding disc 501 and the guide disc 502, thereby adjusting the grinding progress and the rolling speed of the organic fertilizer. The water mist sprayed by the spray pipe 503 softens the surface of the organic fertilizer, making the organic fertilizer being ground more rounded. The ground organic fertilizer particles flow out through the discharge hole 511, pass through the guide disc 502 and the discharge trough 512, and enter the second collecting bin 505, and finally enter the drying box 601 through the third conveying auger 513 for drying.

[0031] When the first pressure roller 311 and the second pressure roller 312 are in operation, the first fan blade 326 and the second fan blade 327 installed in the wind bin 303 are respectively driven to rotate by the fan blade motor 1 309 and the fan blade motor 2 310, so that the airflow in the first pressure roller 311 and the second pressure roller 312 is increased during rotation, and the airflow is introduced into the electric heating bin 602 through the air duct 305 to form hot air.

[0032] When replacing the first pressure roller 311 and the second pressure roller 312, remove the connecting bolts of the bearing seat 318 on the movable support frame 313, move the movable support frame 313 downward, and remove the fixing bolts 321 on the positioning ring 320, so that the first pressure roller 311 and the first clamping frame 328 are loosened, and the second pressure roller 312 and the second clamping frame 329 are loosened, and they are pulled out horizontally, and other types of pressure rollers in the pressure roller bin 332 are installed and used.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
