[0022] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0023] like Figures 1 to 3 As shown, the multi-dimensional mixing mechanism of this utility model's organic fertilizer fermentation device includes a fermentation tank 1, a vertical stirring assembly 2, a horizontal stirring assembly 3, a side scraping assembly 4, and a controller 5. The fermentation tank 1 is the main container of the entire device, with a feed inlet 11 at its top. A sealing cap 13 is installed at the feed inlet 11 to isolate external air after feeding, maintaining the specific environment required for fermentation inside the tank, while preventing impurities from entering and internal gases from escaping. A discharge outlet 12 is located at the bottom of the tank, with a control valve 14 installed at the discharge outlet 12. The control valve 14 can precisely control the timing and amount of material discharge after fermentation, facilitating subsequent collection and processing of the finished organic fertilizer. The vertical stirring assembly 2 is positioned vertically inside the fermentation tank 1, the horizontal stirring assembly 3 is positioned horizontally inside the fermentation tank 1, and the side scraping assembly 4 is located on the side wall of the fermentation tank 1. The side scraping components 4 are all connected to the vertical stirring components 2, so that when the vertical stirring components 2 are running, the horizontal stirring components 3 and the side scraping components 4 move synchronously with them. The vertical stirring components 2 and the horizontal stirring components 3 mix the organic fertilizer in multiple dimensions, thereby improving the uniformity of the material. The side scraping components 4 scrape off the organic fertilizer adhering to the inner wall of the tank, so that it can re-participate in the material mixing and fermentation process, effectively avoiding material waste and improving fermentation efficiency. The controller 5 is set on the outside of the fermentation tank 1 and is electrically connected to the vertical stirring components 2, the horizontal stirring components 3 and the side scraping components 4. The operator can preset parameters such as stirring speed and stirring time through the controller 5. During the fermentation process, the controller 5 accurately controls the coordinated work of each component according to the preset parameters, ensuring that the entire multi-dimensional mixing mechanism is always in the best working state, so as to achieve efficient and stable organic fertilizer fermentation and mixing effect.
[0024] Specifically, the vertical stirring assembly 2 includes a vertical stirring shaft 21 and multiple vertical stirring blades 22. The vertical stirring shaft 21 is made of high-strength and corrosion-resistant material to ensure long-term stable operation in complex fermentation environments. The vertical stirring shaft 21 is vertically installed inside the fermentation tank 1, with its top penetrating the top of the fermentation tank 1 and rigidly connected to the output shaft of the drive motor 23 located outside the fermentation tank 1 via a coupling to ensure stable power transmission. The multiple vertical stirring blades 22 are distributed at intervals along the axial direction of the vertical stirring shaft 21, and the spacing between adjacent vertical stirring blades 22 is optimized according to the height of the fermentation tank 1 and the characteristics of the material. When the drive motor 23 is started, the vertical stirring shaft 21 rotates at high speed under the drive of the motor, and the vertical stirring blades 22 can horizontally tumble and stir the material in the vertical space inside the tank, promoting the mixing of the material in the horizontal direction.
[0025] To ensure the stability of the stirring process, a bearing seat 24 is provided on the vertical stirring shaft 21, and the bearing seat 24 is fixedly installed on the fermentation tank body 1; the bearing seat 24 can support the vertical stirring shaft 21 and reduce its friction and wear during rotation.
[0026] The horizontal stirring assembly 3 includes two horizontal stirring shafts 31 and multiple horizontal stirring blades 32. The horizontal stirring shafts 31 are made of the same high-strength, corrosion-resistant material as the vertical stirring shaft 21. The multiple horizontal stirring blades 32 are evenly distributed along the axial direction of the horizontal stirring shafts 31, and their spacing is optimized according to the height of the fermentation tank 1 and the material characteristics. To achieve power transmission between the vertical stirring assembly 2 and the horizontal stirring assembly 3, the two horizontal stirring shafts 31 are horizontally arranged inside the fermentation tank 1 and symmetrically arranged on both sides of the vertical stirring shaft 21. A first bevel gear 33 is coaxially fixed on the vertical stirring shaft 21, and a second bevel gear 34 is provided at the end of each of the two horizontal stirring shafts 31 that is close to each other. The second bevel gear 34 is connected to the first bevel gear 32. When the drive motor 23 drives the vertical stirring shaft 21 to rotate, the first bevel gear 33 on the vertical stirring shaft 21 rotates accordingly. Through gear meshing, the power is transmitted to the second bevel gear 34 on the two horizontal stirring shafts 31, so that the horizontal stirring shafts 31 rotate synchronously at a speed matching that of the vertical stirring shaft 21, thereby driving the horizontal stirring blades 32 to quickly stir and disperse the material. In addition, a protective sleeve 35 is provided at the gear meshing point. The protective sleeve 35 is connected to the fermentation tank 1 through the first connecting rod 36 to ensure the stable installation of the protective sleeve 35. The protective sleeve 35 has a sealing structure inside to prevent the material and water vapor during the fermentation process from entering the gear meshing area and affecting the transmission performance.
[0027] Preferably, the movable end of each horizontal stirring blade 32 is a spoon-shaped structure with its opening facing the rotation direction of the horizontal stirring shaft 31. When the horizontal stirring shaft 31 rotates, the spoon-shaped structure can efficiently scoop up the material and use centrifugal force to throw the material along the spoon wall, forming a material flow with a certain impact force. On the one hand, this material flow can exert a strong pushing and diffusion effect on the surrounding accumulated material, breaking the agglomeration state of the material and making the material more evenly distributed in the horizontal direction. On the other hand, the thrown material collides and mixes with the material flow under the action of other stirring blades, further enhancing the mixing effect.
[0028] Preferably, the bottom of the fermentation tank 1 is an inverted cone structure, which conforms to the principles of fluid mechanics and can effectively guide the material to converge towards the discharge port 12; the radial lengths of the vertical stirring blades 22 and the horizontal stirring blades 32 located within the cone structure decrease, so that their stirring range corresponds to the inverted cone structure.
[0029] The side scraping assembly 4 includes a scraper 41 and a second connecting rod 42. The scraper 41 is made of a high-strength material with a certain degree of flexibility and fits against the inner wall of the fermentation tank 1. One end of the second connecting rod 42 is connected to the scraper 41 and the other end is connected to the vertical stirring shaft 21. When the vertical stirring shaft 21 rotates, it drives the movement of the second connecting rod 42, which in turn drives the scraper 41 to perform a periodic scraping action along the side wall of the tank to scrape off the dried material adhering to the side wall of the tank.
[0030] Preferably, the first connecting rod 36 and the second connecting rod 42 are triangular prism structures with their edges facing upwards. The three sides of the triangular prism form a stable triangular support system. Compared with common cylindrical or square structures, the triangular prism structure can withstand greater bending stress and shear force under the same cross-sectional area. When the equipment is running, the connecting rod needs to withstand the vibration and torque generated by the material flow. The triangular prism structure, with its stable mechanical properties, ensures that the connecting rod is not easily deformed under complex stress conditions, thus ensuring the stable operation of the entire mixing mechanism. The upward-facing arrangement reduces the contact area during the unloading process after fermentation. According to the principles of material mechanics, the smaller the contact area, the weaker the adhesion between the material and the surface of the connecting rod. This makes it difficult for the material to stay on the surface of the connecting rod and makes it easier for it to slide down to the discharge port 12 along with the mainstream material, making the unloading process more efficient.
[0031] This utility model discloses a multi-dimensional mixing mechanism for an organic fertilizer fermentation device. During operation, the sealing cover 13 of the inlet 11 is first opened, and organic raw materials, microorganisms, and additives are added to the fermentation tank 1 in proportion. After addition, the sealing cover 13 is immediately closed to ensure the tank's interior is isolated from the outside. During fermentation, the drive motor 23 drives the vertical stirring shaft 21 to rotate, and the vertical stirring blades 22 begin to stir the material horizontally. Through bevel gear transmission, the horizontal stirring shaft 31 is synchronously driven to rotate, causing the material to tumble up and down, ensuring uniform mixing in three-dimensional space. The second connecting rod 42 synchronously converts the circular motion of the vertical stirring shaft 21 into the reciprocating motion of the scraper 41, which scrapes off any adhering material layers, allowing them to re-participate in the mixing process.
[0032] The multi-dimensional mixing mechanism of this utility model for an organic fertilizer fermentation device can be installed, connected, or set up using common mechanical methods. Any method that can achieve its beneficial effects can be implemented.
[0033] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
