[0032] It should be noted that: the fertilizer storage unit in the present invention adopts the existing electric heating drying cylinder 3 to connect the external power supply and control the heating temperature when drying the internal fertilizer. When the electric heating drying cylinder 3 is heated, the fertilizer inside the storage chamber 5 can be heated and dried. The water vapor generated during the heating process will be discharged outward along the various ventilation pipe openings 10 on the top of the electric heating drying cylinder 3, thereby achieving the purpose of effective dehumidification.

[0033] In addition, when the electric heating drying cylinder 3 needs to spirally reciprocate and swing the fertilizer inside it, the double-effect mixing mechanism needs to be started, and the operation of the top driving member above the double-effect mixing mechanism drives the entire electric heating drying cylinder 3 to swing back and forth as needed.

At the same time, the water vapor produced during the heating process will be continuously discharged to the outside, reducing the water vapor content inside the storage chamber 5 and improving the dryness of the fertilizer.

When the driving pinion 9 is running, it can drive the driven large gear 13 to run, thereby achieving the purpose of linking the operation of the fertilizer storage unit inside the driven large gear 13.

[0041] During the reciprocating small-amplitude swinging of the fertilizer storage unit, the fertilizer inside the storage chamber 5 can be effectively shaken, thereby cooperating with the internal hot air blowing to achieve efficient drying of the fertilizer. During the shaking process, gaps for air flow will be formed between the organic fertilizers, thereby improving the ventilation effect during hot air drying and improving the drying efficiency.

[0042] In addition, during the shaking process, the spiral conveying of the mixing conveyor can effectively drive the movement of the organic fertilizer blocks inside the storage chamber 5, realize double shaking to realize the hot air entering the storage chamber 5 to form a multi-channel circulation mode, thereby promoting the improvement of the drying effect.

[0043] In any of the above schemes, it is preferred that the inner end of the mixing and conveying member movably and sealedly extends into the storage chamber 5 and is used to drive the hollow shaft 15 of the spiral blade 14 installed therein, and the left and right ends of the hollow shaft 15 are both movably extended to the outside of the end cover 4 on its corresponding side.

[0044] In any of the above schemes, it is preferred that a pneumatic dryer is fixedly installed on the middle outer wall of the semicircular docking ring 11 on the left side, the air outlet end of the pneumatic dryer is connected to the left end of the hollow shaft 15, and a plurality of hot air holes 16 for communicating with the interior of the hollow shaft 15 are provided on the outer wall of the hollow shaft 15 inside the storage chamber 5, and the hot air holes 16 are used to transport hot air to the interior of the storage chamber 5.

[0045] It should be noted that the mixing and conveying member mainly relies on the rotation of the spiral blades 14 to drive the internal fertilizer to move back and forth, thereby cooperating with the hot air blown out by the hot air holes 16 set on the hollow shaft 15 to complete the efficient drying of the internal fertilizer.

[0046] The pneumatic dryer mainly blows hot air to the hot air holes 16 during operation. After the hot air enters, it blows the organic fertilizers at different positions, thereby achieving the purpose of efficient drying.

[0047] In any of the above schemes, it is preferred that the pneumatic dryer includes a fan fixing frame 17 fixedly mounted on the middle outer wall of the semicircular docking ring 11 on the left side, and a temperature-controlled hot air blower 18 is fixedly mounted inside the fan fixing frame 17, and the air outlet of the hot air blower 18 is movably inserted into the left end tube cavity of the hollow shaft 15.

[0048] It should be noted that the pneumatic dryer mainly relies on the hot air blower 18 to provide hot air when working, and the hot air continuously enters the left end tube cavity of the hollow shaft 15, thereby continuously drying the inside of the storage cavity 5 and improving the fertilizer drying effect.

[0049] In any of the above schemes, it is preferred that the mixing and conveying member includes a motor fixing frame 19 fixedly mounted on the middle outer wall of the semicircular docking ring 11 on the right side, and a conveying motor 20 is fixedly mounted inside the motor fixing frame 19, and the motor shaft of the conveying motor 20 moves through the end cover 4 and extends into the storage chamber 5 and is fixedly connected to the right end of the hollow shaft 15.

[0050] The hollow shaft 15 is mainly driven by the conveying motor 20 to rotate the fixed axis during operation, and the spiral blades 14 can be driven to rotate forward or reverse during the rotation, so as to achieve the purpose of conveying the organic fertilizer inside the storage chamber 15 to the left or right.

[0051] Specific working principle: When the device is working, the fertilizer storage unit is used as the storage unit, and the rigid feeding pipes 1 at both ends cooperate with the external feeding equipment to complete the feeding into the storage unit. After feeding, the double-effect mixing mechanism is started to realize the continuous stirring and conveying of the internal organic fertilizer, thereby achieving heating and drying of the internal fertilizer in the conveying state, effectively improving the drying effect and efficiency. When it is necessary to control the internal fertilizer to swing greatly to achieve the purpose of accelerating the mixing effect of the internal hot air and fertilizer, the top drive is controlled to open and drive the double-effect mixing mechanism to rotate and swing back and forth as needed, and finally achieve the purpose of controlling the reciprocating swing of the internal fertilizer, and realize the efficient drying of the internal fertilizer. In addition, in order to improve the drying effect, the fertilizer inside the storage chamber 5 can be effectively shaken during the reciprocating small-amplitude swinging of the fertilizer storage unit, thereby cooperating with the internal hot air blowing to achieve efficient drying of the fertilizer. During the shaking process, gaps for air flow will be formed between the organic fertilizers, thereby improving the ventilation effect during hot air drying and improving the drying efficiency. Specifically, during the shaking process, the spiral conveying of the mixing and conveying parts can effectively drive the movement of the organic fertilizer blocks inside the storage chamber 5, realizing double shaking to realize the hot air entering the storage chamber 5 to form a multi-channel circulation mode, thereby promoting the improvement of the drying effect.

[0052] In summary, it can be seen that the present biological organic fertilizer uniform drying device adopts a double-effect drying method of external electric heating and internal hot air drying when drying, which can better ensure the drying effect; the double-effect mixing mechanism relies on the operation of the mixing conveying member to drive the spiral blade 14 to rotate forward or flip inside the storage chamber 5 when drying the moist organic fertilizer entering the inside thereof to achieve the purpose of stirring and conveying the organic fertilizer, thereby improving its drying effect, and relying on the left and right conveying and stirring of the spiral blade 14 during the drying process to make the drying and heating more uniform; when drying, spiral conveying is adopted internally, and the top driving member is coordinated externally to realize fixed-axis swing, thereby ensuring that the built-in organic fertilizer is in a shaking position state, improving the mobility of the internal fertilizer during electric drying and internal pneumatic hot air drying, ensuring the rapid circulation of internal heat, and improving the drying efficiency.
