[0031] Refer to Figures 1-3The present invention discloses a fermentation system for preparing organic fertilizer by using garden waste. The fermentation system for preparing organic fertilizer by using garden waste can process the recycled garden waste and ferment it into organic fertilizer.

Among them, the fermentation tank 100 includes a horizontal hardened floor 101, on which two side walls 102 extending upward and parallel to each other are arranged, and a bottom wall 103 is arranged at one end between the two side walls 102, and the two side walls 102 and the bottom wall 103 form a U-shaped fermentation tank 100 on the hardened floor 101; a guide rail 200 is arranged on the top of each side wall 102, and the guide rails 200 extend parallel to each other along the length direction of the side walls 102; the horizontal axis 300 includes a supporting body 301 spanning over the two guide rails 200, and two rollers 302 are respectively arranged at both ends of the supporting body 301 and supported on the guide rails 200, and a rotatable transmission shaft 303 is arranged on the supporting body 301, and the length direction of the transmission shaft 303 is perpendicular to the guide rails 200, and the two ends of the transmission shaft 303 are respectively connected to the other ends of the supporting body 301. A roller 302 is transmission connected in the middle, a first motor 304 is arranged on the support body 301, and the first motor 304 is transmission connected with the transmission shaft 303; the vertical shaft 400 is arranged on the support body 301 of the horizontal shaft 300, and can slide back and forth along the length direction of the transmission shaft 303. A driving device 401 is also arranged on the support body 301 to control the vertical shaft 400 to slide back and forth on the support body 301 along the length direction of the transmission shaft 303, and to control the vertical shaft 400 to reciprocate in the vertical direction; the stirring device 500 includes a mounting seat 501 arranged at the lower end of the vertical shaft 400, a stirring shaft 502 parallel to the transmission shaft 303 can be rotatably arranged on the mounting seat 501, a plurality of stirring paddles 504 for stirring are arranged on the stirring shaft 502, and a second motor 503 is arranged on the mounting seat 501 to be transmission connected with the stirring shaft 502.
[0033] When using garden waste to ferment organic fertilizer, the collected garden waste can be screened first, and large branches and hard branches with large diameters and difficult to ferment can be screened out as raw materials for biomass fuel, or they can be used as raw materials for organic fertilizer after preliminary crushing, and the remaining soft rotten branches, leaves, broken grass, etc. can be crushed into organic fertilizer raw materials after removing impurities and gravel. Then, the garden waste raw materials are mixed with animal feces (such as poultry excrement, pig, cattle and sheep excrement collected in a farm, etc.), mixed with the bacterial agent used for fermentation, and then put into the fermentation tank 100 of the organic fertilizer fermentation system using garden waste for fermentation.
[0034] During the fermentation process, the fermentation raw materials containing garden waste are stacked in the fermentation tank 100 and stacked and fermented in a direction away from the bottom wall 103 starting from the bottom wall 103. During the fermentation process, when it is necessary to turn the fermentation raw materials regularly, the stirring device 500 can be driven to turn the stacked fermentation raw materials with the support of the horizontal shaft 300 and the vertical shaft 400.
[0035] The specific turning operation is as follows: First, the second motor 503 drives the stirring shaft 502 to rotate, and the rotating stirring shaft 502 can drive the stirring paddle 504 to contact the fermentation raw materials and turn them; then, the horizontal shaft 300 reciprocates along the length direction of the guide rail 200 on the guide rail 200 to support the movable stirring paddle 504 to move back and forth in the length direction of the fermentation tank 100. On this basis, the vertical shaft 400 reciprocates in the length direction of the horizontal shaft 300 to support the movable stirring paddle 504 to move back and forth in the width direction of the fermentation tank 100. On this basis, the vertical shaft 400 reciprocates vertically on the horizontal shaft 300 to support the movable stirring paddle 504 to move back and forth in the depth direction of the fermentation tank 100; thus, the movable stirring paddle 504 can move around in all directions in the fermentation tank 100 and turn the materials.
[0036] Among them, the movement of the horizontal shaft 300 on the guide rail 200 is realized by the first motor 304 driving the roller 302. Among them, the movement of the vertical shaft 400 on the horizontal shaft 300 is controlled by the driving device 401. The driving device 401 includes a connecting seat 402 and two first slide rails 403 arranged on the support body 301. The length direction of the first slide rails 403 is perpendicular to the guide rail 200. The connecting seat 402 is slidably connected to the first slide rails 403 through the first slider. A first rack 404 parallel to the first slide rails 403 is also arranged on the support body 301, and a third motor 405 is arranged on the connecting seat 402. A first gear is arranged on the output shaft of the third motor 405, and the first gear meshes with the first rack 404 for transmission. At the same time, a vertical second slide rail 406 is arranged on the vertical shaft 400. The connecting seat 402 is slidably connected to the second slide rail 406 through the second slider. A vertical second rack 407 is also arranged on the vertical shaft 400. A fourth motor 408 is arranged on the connecting seat 402. A second gear 409 is arranged on the output shaft of the fourth motor 408, and the second gear 409 meshes with the second rack 407 for transmission. Thus, the translation of the vertical shaft 400 on the horizontal shaft 300 can be controlled by the third motor 405, and the lifting of the vertical shaft 400 can be controlled by the fourth motor 408, thereby controlling the stirring of the stirring device 500.
[0037] Among them, both ends of the stirring shaft 502 of the stirring device 500 extend away from the mounting seat 501. A number of stirring rods 505 are spirally distributed along the length direction of the stirring shaft 502 on the stirring shafts 502 on both sides of the mounting seat 501. The stirring paddle 504 includes the stirring rods 505 and the stirring blades 506 arranged on the stirring rods 505. The length direction of the stirring rod 505 is perpendicular to the stirring shaft 502. One end of the stirring rod 505 is fixedly connected to the stirring shaft 502, and the stirring blade 506 is fixedly arranged at the other end. The stirring blade 506 has a radian inclined towards the mounting seat 501. The second motor 503 drives the stirring paddle 504 to move and stir the fermentation raw materials. During the stirring process, the radian of the stirring blade 506 can effectively push and squeeze the fermentation raw materials, so that the fermentation raw materials at different positions are stirred and mixed with each other. Further, when the stirring shaft 502 rotates, it rotates towards the side where the radian opening direction of the stirring blade 506 is located to form a sprinkling effect.
[0038] Among them, a number of fermentation tanks 100 are arranged on the hardened floor 101. The fermentation tanks 100 are arranged in a row along the width direction of the fermentation tank 100. Adjacent fermentation tanks 100 share a side wall 102. Guide rails 200 are arranged on each side wall 102. The specifications and spacings of the two guide rails 200 on each fermentation tank 100 are the same. A set of devices such as the horizontal shaft 300 and the vertical shaft 400 for driving the stirring device 500 to move can be shared by multiple fermentation tanks 100. Among them, the method of moving the devices such as the horizontal shaft 300 and the vertical shaft 400 to another fermentation tank 100 can adopt a traveling crane or a special moving vehicle.
[0039] Among them, the U-shaped fermentation tank 100 surrounds and supports the fermentation raw materials on multiple sides, which is conducive to the formation of a relatively thick thickness after the fermentation raw materials are piled up in the fermentation tank 100, and is conducive to the occurrence of the fermentation reaction, solving the problem that the fermentation temperature inside the fermentation raw materials is not high enough during the natural stacking fermentation process. At the same time, after the turning of the materials is completed, it is very convenient to cover the remaining surface of the fermentation raw material pile in the fermentation tank 100 with a film to improve the fermentation efficiency. Among them, the non-closed opening side of the fermentation tank 100 can facilitate the entry and exit of forklifts, and after the fermentation raw materials that meet the fermentation requirements are removed, they can be naturally stacked or packed for treatment.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
