Detailed Implementation

[0016] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0017] like Figures 1 to 2 As shown, a microbial fertilizer protectant preparation device includes a cylinder 1, a screening and dispersing mechanism 3 and a stirring mechanism arranged sequentially inside the cylinder 1 along the material falling direction, that is, the material is first screened and dispersed by the screening and dispersing mechanism 3, and then stirred and mixed by the stirring mechanism.

[0018] The screening and dispersing mechanism 3 includes a screen 2 located inside the cylinder 1, a dispersing shaft 4 positioned above the screen 2, dispersing blades 5 mounted on the dispersing shaft 4 for dispersing agglomerated materials, and a drive motor 10 for driving the dispersing shaft 4 to rotate. The dispersing shaft 4 is connected to the drive motor 10 via a coupling. Agglomerated materials are intercepted on the screen 2 and located on the rotation path of the dispersing blades 5. The number of dispersing blades 5 is two or more. The dispersing blades 5 have a long strip structure and are hollow inside, reducing their volume and weight, which helps to reduce energy consumption.

[0019] The dispersing blades 5 are evenly distributed around the dispersing shaft 4, and the movement path of the dispersing blades 5 corresponds to the setting of the clumps on the screen 2. The screen 2 intercepts the clumps of material, and the intercepted clumps are located on the rotation path of the dispersing blades 5. The movement of the dispersing blades 5 impacts and breaks up the clumps of material, thereby improving the mixing effect of subsequent stirring and mixing.

[0020] A circular annular pad 7 is coaxially fitted onto the dispersing shaft 4, positioned between the dispersing blades 5 and the screen 2. The annular pad 7 ensures that the dispersing blades 5 and the screen 2 are spaced apart. The spacing can be adjusted by placing different pads 7. The spacing should be slightly larger than the normal particle size of the material, allowing a single normal material to pass through while blocking multiple stacked or clumped materials. The spaced arrangement between the dispersing blades 5 and the screen 2 ensures that the clumped material, while being impacted, also experiences a certain shearing force due to the gaps, thus improving the dispersing effect. Similarly, the dispersing blades 5 are spaced apart from the inner wall of the cylinder 1. The spacing, controlled to be slightly larger than the normal particle size, allows for shearing of the clumped material from multiple directions.

[0021] Since the rotating dispersing blades 5 are installed, the agglomerated material may move toward the edge of the cylinder 1 when it is impacted, and then fall off the edge of the screen 2. Therefore, an annular guide plate 9 is provided below the screen 2 on the cylinder 1. The annular guide plate 9 is inclined toward the stirring structure in the middle of the cylinder 1 to guide the edge material to the stirring structure, which is beneficial to improving the mixing effect of the dispersing turntable.

[0022] The stirring mechanism includes a drive shaft 11 coaxially arranged with the dispersing shaft 4 and stirring blades 12 arranged on the drive shaft 11. The drive shaft 11 is driven by a drive motor 10, and the screen 2 is provided with through holes for the drive shaft 11 to pass through. The drive shaft 11 and the dispersing shaft 4 are connected by a bushing to form an integral drive shaft 11 structure. The drive motor 10 drives the dispersing shaft 4 and the drive shaft 11 to rotate synchronously.

[0023] In another connection method, the drive shaft 11 can serve as the dispersing shaft 4, eliminating the need for a separate dispersing shaft. The top of the drive shaft 11 is connected to the drive motor 10 via a coupling. A circular annular connector 6 is fitted onto the drive shaft 11, and the dispersing blades 5 are disposed on the outer peripheral wall of the circular annular connector 6. Specifically, a strip key 19 is provided above the drive shaft 11, and a keyway matching the strip key 19 is provided on the inner wall of the circular annular connector 6. The drive shaft 11 and the circular annular connector 6 are connected via a key. A pad 8 is provided between the circular annular connector 6 and the inner top wall of the cylinder 1. The pad 8 and the pad block 7 cooperate to fix the axial position of the circular annular connector 6.

[0024] The cylinder 1 includes a cylinder body 13, support legs 16 located at the bottom of the cylinder body 13, and a lid detachably connected to the cylinder body 13. The detachable structure of the cylinder body 1 facilitates the replacement of the pad 7 and the pad cylinder 8 to adjust the screen 2. The support legs 16 support the cylinder body 11. Steps are provided on the inner circumferential wall of the cylinder body 13, and the screen 2 overlaps at the steps. The stirring blades 12 are detachably mounted on the drive shaft 11 via pins. A keyway passes through the annular connecting piece 6. When replacement is needed, the lid 14 is removed upwards, causing the lid 14, along with the entire stirring mechanism and the screening and dispersing mechanism 3, to move outside the cylinder body 13. The stirring blades 12 are then removed. At this point, the screen 2, pad 7, annular connecting piece 6, and pad cylinder 8 can be slid out sequentially from the bottom of the drive shaft 11. Different sizes of pad 7 and pad cylinder 8 can then be replaced. The inner radius of the pad cylinder 8 must not be less than the maximum distance from the strip key 19 to the centerline of the drive shaft 11. In addition, a handle 1515 is provided on the outside of the lid to facilitate the application of force to pull out the lid 1414.

[0025] An observation window is provided on the cylinder 1 for observing the internal mixing situation, and preferably the observation window is located on the cylinder body 13.

[0026] To facilitate material discharge from the cylinder 1, the inner bottom wall of the cylinder 1 is funnel-shaped, and a discharge channel 17 is provided at the bottom of the inner bottom wall of the cylinder 1. A valve is provided on the discharge channel 17, and a feed channel 18 is provided on the lid of the cylinder 1.

[0027] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
