[0002] At present, the hot air circulating drying box suitable for the drying treatment of the granular organic fertilizer on the market is usually composed of a drying box body and a storage structure. When this kind of hot air circulating drying box is actually used, the user places the granular organic fertilizer in the storage structure in the drying box in advance, and then injects high-temperature gas into the drying box. In this process, the high-temperature gas flows in the drying box, so as to realize the removal of the moisture in the granular organic fertilizer by the high-temperature gas. However, when this kind of hot air circulating drying box is actually used, although it can achieve good hot air circulating drying effect on the organic fertilizer, the storage structure is not provided with a good organic fertilizer mixing structure. This kind of storage structure is usually provided with a breathable box-shaped structure. Before the organic fertilizer is placed in the drying box, the staff needs to use the mixing structure to evenly spread the organic fertilizer in the storage structure in advance. However, when the organic fertilizer is dried in the drying box, the organic fertilizer is prone to thermal expansion and cold contraction. This leads to the fact that when the organic fertilizer is dried in the drying box, one side of the organic fertilizer is prone to over-drying, while the other side of the organic fertilizer is prone to being relatively wet, thereby causing the organic fertilizer to be inconvenient to dry in the drying box.

[0003] Therefore, the application provides an efficient hot air circulating drying box for organic fertilizer to solve the problem that the organic fertilizer is inconvenient to be quickly dried in the drying box. SUMMARY

[0020] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0022] Example 1: Please refer toFigures 1-10 As shown, the present invention provides a technical solution: This invention relates to a high-efficiency hot air circulating drying box for organic fertilizer, comprising a first storage box 12 and a second storage box 13. A collection rack 8 is placed inside the cavities of both the first and second storage boxes 12 and 13. A storage box 3 is inserted into the collection rack 8. Rotating rods 46 are evenly spaced inside the storage box 3 and are rotatably connected to it. One end of each rotating rod 46 is connected to an air supply structure. Rotating tubes 42 are evenly spaced on the storage box 3. A fixed tube 41 is rotatably connected between every two first storage boxes 12. Protruding teeth 43 penetrate the rotating tubes 42. A sealing ring 415 is fixedly connected inside the rotating tube 42 near the inner wall of the storage box 3. An air outlet 44 is passed through the fixed tube 41. A first driving structure is provided on the protruding tooth 43. A second driving structure is provided on the air outlet 44. Air outlet holes are opened in a matrix on the side wall of the air outlet 44. The diameter of the air outlet holes needs to be smaller than the diameter of the granular organic fertilizer. A monitoring and control system 16 is connected to the first driving structure and the second driving structure. The monitoring and control system 16 includes a PLC controller, a temperature sensor and a timing switch. In actual use, the sealing ring 415 can seal the rotating tube 42 located at both ends, which can prevent the high temperature gas inside the rotating tube 42 and the fixed tube 41 from being discharged. When the granular organic fertilizer is stored inside the storage box 3, the air outlet 44 can drive the surrounding granular organic fertilizer to flow around the protruding teeth 43.

[0023] A mounting bracket 413 is distributed below the rotating rod 46. The upper part of the mounting bracket 413 is fixedly connected to the fixing tube 41. The mounting bracket 413 is fixedly connected to the inner wall of the storage box 3. In use, the second drive structure drives the air outlet chamber 44 to extend and retract on the fixed tube 41, so that the granular organic fertilizer around the air outlet chamber 44 flows to the area around the protruding teeth 43. Then, the first drive structure drives the protruding teeth 43 to extend and retract on the rotating tube 42, so that the protruding teeth 43 drive the granular organic fertilizer inside the storage box 3 to surge.

[0024] The gas supply structure includes an exhaust chamber 416 fixed on a rotating rod 46. The exhaust chamber 416 and the sealing ring 415 are rotatably connected. A guide pipe 410 is fixedly connected to the exhaust chamber 416. A transmission gear 4 is fixedly connected to the guide pipe 410. The exhaust chamber 416 is used to discharge the high-temperature gas inside the guide pipe 410 to the interior of the fixed pipe 41 and the rotating pipe 42. The sealing ring 415 has an exhaust hole on the side facing the rotating tube 42, which can transport the high-temperature gas inside the guide tube 410 to the inside of the rotating tube 42.

[0025] The first drive structure includes a pressing plate 48 fixedly connected to the lower end of the protruding tooth 43, a storage spring 47 fixedly connected between the pressing plate 48 and the rotating tube 42, a toggle plate 411 fixedly connected to the bottom surface of the pressing plate 48, a toggle block 414 abutting against the toggle plate 411, and a toggle block 414 fixedly connected to the rotating rod 46. The contact area between the actuating plate 411 and the actuating block 414 is provided with rounded corners. When the actuating block 414 moves the actuating plate 411, the storage spring 47 can store force and work. Thus, when the actuating block 414 does not move the actuating plate 411, the storage spring 47 drives the actuating plate 411 to reset through the pressing plate 48, thereby realizing that the protruding teeth 43 intermittently extend on the rotating tube 42.

[0026] The second drive structure includes a toggle seat 49 fixedly connected to the lower end of the air outlet chamber 44. The toggle seat 49 has a T-shaped structure. A connecting spring 412 is fixedly connected between the toggle seat 49 and the fixed tube 41. The lower end of the toggle seat 49 abuts against a toggle tooth 45. The toggle tooth 45 is fixedly connected to the rotating rod 46. When the actuating tooth 45 actuates the actuating seat 49, the connecting spring 412 can store energy. When the actuating tooth 45 does not actuate the actuating seat 49, the connecting spring 412 can drive the actuating seat 49 to reset, thereby enabling the actuating seat 49 to intermittently drive the air chamber 44 to extend on the fixed tube 41.

[0027] The air outlet 44 extends through the fixed tube 41 to the outside of the fixed tube 41. The rear sides of the first storage box 12 and the second storage box 13 are both provided with connecting frames 6. A pull rack 131 meshes on the transmission gear 4. The pull rack 131 and the connecting frame 6 are fixedly connected. The lower end of the connecting frame 6 is detachably connected to an electric push rod 132. The electric push rod 132 is connected to the monitoring and control system 16. In actual use, the rotating rod 46 can continuously rotate inside the storage box 3. When the storage box 3 contains granular organic fertilizer, the actuating tooth 45 actuates the actuating seat 49, and the connecting spring 412 can store power. When the actuating tooth 45 does not actuate the actuating seat 49, the connecting spring 412 can drive the actuating seat 49 to reset, thereby enabling the actuating seat 49 to intermittently drive the air outlet 44 to extend on the fixed tube 41. During this process, the granular organic fertilizer will flow around the extending tooth 43. When the actuating block 414 actuates the actuating plate 411, the power storage spring 47 can store power. Therefore, when the actuating block 414 does not actuate the actuating plate 411, the power storage spring 47 drives the actuating plate 411 to reset through the squeezing plate 48, thereby enabling the extending tooth 43 to intermittently extend on the rotating tube 42, so that the extending tooth 43 drives the granular organic fertilizer inside the storage box 3 to surge. It should be noted that the end of the air outlet 44 is rounded. The advantage of this design is that when the air outlet 44 pushes the granular organic fertilizer inside the storage box 3, the granular organic fertilizer can flow around the protruding teeth 43. At the same time, the staff can set the shape of the protruding teeth 43 according to the actual situation. For ease of understanding, the shape of the protruding teeth 43 shown in this document is a rectangular plate structure. Example 2: Please refer to Figures 1-10 As shown, based on Embodiment 1, the present invention provides a technical solution: A shielding frame 11 is fixedly connected to both the first storage box 12 and the second storage box 13. The shielding frame 11 on the first storage box 12 and the shielding frame 11 on the second storage box 13 are fixedly connected. A through hole 121 is opened on the shielding frame 11. A double-headed hydraulic cylinder 94 is distributed between the first storage box 12 and the second storage box 13. A push plate 92 is fixedly connected to both ends of the double-headed hydraulic cylinder 94. An air guide pipe 9 is fixedly connected to the push plate 92 at equal intervals. A sleeve pipe 93 is fixedly connected to the air guide pipe 9 at equal intervals. The sleeve pipe 93 passes through the through hole 121, passes through the first storage box 12 and the second storage box 13, and is sleeved with the guide pipe 410. The flow guide cavity 2 is provided with a protective door that seals the openings of the first storage box 12 and the second storage box 13. The function of the protective door is to seal the openings of the first storage box 12 and the second storage box 13 to prevent high-temperature gas from escaping from the openings of the first storage box 12 and the second storage box 13.

[0028] The sleeve 93 is internally fixedly connected to a sealing ring 95 that can abut against the guide tube 410. The upper end of the air guide tube 9 is fixedly connected to a connecting end tube 91. Both the connecting end tube 91 and the sleeve 93 are connected to the inner cavity of the air guide tube 9. When used under normal conditions, the sleeve 93 is not connected to the guide pipe 410. When the double-headed hydraulic cylinder 94 is working, the double-headed hydraulic cylinder 94 can drive the air guide pipe 9 to move closer to the shield 11 through the push plate 92, so that the sleeve 93 and the guide pipe 410 are connected at the same time. The sealing ring 95 can abut against the guide pipe 410 to achieve a sealed connection between the sleeve 93 and the guide pipe 410. It should be noted that the double-headed hydraulic cylinder 94 is fixed between the two shields 11.

[0029] A gas collecting box 5 is distributed above the first storage box 12 and the second storage box 13. An electric heating plate 14 is fixedly connected to the gas collecting box 5. A flow guiding cavity 2 is fixedly connected to both sides of the gas collecting box 5. A gas collecting cavity 7 is fixedly connected to the lower end of the flow guiding cavity 2. A mounting box 123 is fixedly connected to the gas collecting cavity 7 near the shielding frame 11. An electric push rod 132 is stored inside the mounting box 123. An air inlet 122 is opened on the gas collecting cavity 7. The inner cavity of the gas collecting cavity 7 is connected to the inner cavity of the first storage box 12 and the second storage box 13 through the air inlet 122. The heating plate 14 can continuously heat the air inside the gas collecting box 5, thereby forming high-temperature gas inside the gas collecting box 5.

[0030] The air collection box 5 includes an installation cavity 51 and an air inlet end 52 located above the shielding frame 11. A transmission rod 102 is rotatably connected inside the air collection box 5. A humidity sensor 15 is connected to the air collection box 5. The humidity sensor 15 can detect the humidity inside the air collection box 5 in real time and then transmit the detection information to the monitoring and control system 16. Collection hoods 103 are relatively distributed inside the installation cavity 51. The receiving end of the collection hood 103 is connected to the inner cavity of the air collection box 5, and the discharge end of the collection hood 103 is connected to the connecting pipe 91.

[0031] A transmission blade 101 is fixedly connected to the transmission rod 102 near the receiving end of the collection cover 103. A transmission motor 10 is fixedly connected to one end of the transmission rod 102. The transmission motor 10 is detachably connected to the guide cavity 2. An exhaust pump 1 is detachably connected to the air collection box 5. The receiving end of the exhaust pump 1 is connected to the inner cavity of the air collection box 5. In actual use, the output shaft of the drive motor 10 can drive the drive blade 101 to work through the drive rod 102. At this time, the high temperature gas inside the gas collecting box 5 can enter the interior of the gas guide pipe 9 through the collecting cover 103. During use, the PLC controller has a built-in computer control program. The temperature sensor is used to detect the temperature generated by the heating plate 14 when it is working, and the timer switch is used to control the duration of operation of the heating plate 14. The operator can set the preset value required for drying the organic fertilizer in the computer control program according to the drying requirements of the organic fertilizer. Then, the temperature sensor detects the temperature generated by the heating plate 14 in real time. When the temperature reaches the preset value, the PLC controller controls the timer switch to work. At this time, the heating plate 14 does not work. The computer control program can also set the duration for which the heating plate 14 is turned off. When the duration for which the PLC controls the timer switch to work reaches the preset value, the timer switch can control the heating plate 14 to work again.

[0032] Working principle: In actual use, the staff first puts the granular organic fertilizer into the storage box 3, and then places the storage box 3 containing the granular organic fertilizer into the inside of the collection rack 8. The collection rack 8 can use the storage box 3 to move the organic fertilizer into the inside of the first storage box 12 and the second storage box 13. During this process, the electric heating plate 14 can continuously heat the air inside the gas collection box 5, thereby forming high temperature gas inside the gas collection box 5. Then the staff seals the opening of the first storage box 12 and the second storage box 13 with the protective door on the guide cavity 2. Subsequently, the monitoring and control system 16 starts the drive motor 10. The output shaft of the drive motor 10 can drive the drive blade 101 through the drive rod 102. The drive blade 101 can drive the high-temperature gas inside the gas collection box 5 to enter the interior of the gas guide pipe 9 through the collection cover 103. At this time, the double-headed hydraulic cylinder 94 can drive the gas guide pipe 9 to move closer to the shield frame 11 through the push plate 92. At the same time, the sleeve pipe 93 and the guide pipe 410 are sleeved together. The sealing ring 95 can abut against the guide pipe 410 to achieve the sealing sleeve connection between the sleeve pipe 93 and the guide pipe 410, so that the high-temperature gas inside the gas guide pipe 9 can be transported to the interior of the exhaust chamber 416. During this process, the monitoring and control system 16 activates the electric push rod 132 intermittently. The output end of the electric push rod 132 can drive the rack 131 to move on the first storage box 12 and the second storage box 13 through the connecting frame 6. This allows the rack 131 to drive the rotating rod 46 to rotate through the transmission gear 4. The rotating rod 46 can continuously rotate inside the storage box 3. When granular organic fertilizer is collected inside the storage box 3, the actuating tooth 45 actuates the actuating seat 49, and the connecting spring 412 can store energy. When the actuating tooth 45 does not actuate the actuating seat 49, the connecting spring 412 can work. Spring 412 can drive the actuating seat 49 to reset, thereby enabling the actuating seat 49 to intermittently drive the air outlet 44 to extend on the fixed tube 41. During this process, granular organic fertilizer will flow around the protruding teeth 43. When the actuating block 414 moves the actuating plate 411, the storage spring 47 can store force. Thus, when the actuating block 414 does not move the actuating plate 411, the storage spring 47 drives the actuating plate 411 to reset through the squeezing plate 48, thereby enabling the protruding teeth 43 to intermittently extend on the rotating tube 42, and enabling the protruding teeth 43 to drive the granular organic fertilizer inside the storage box 3 to surge. When the air outlet chamber 44 drives the organic fertilizer to flow around the protruding teeth 43, the high-temperature gas discharged from the air outlet chamber 44 will come into uniform contact with the organic fertilizer, thereby achieving rapid drying of the organic fertilizer inside the storage box 3. Since the first storage box 12 and the second storage box 13 are in a closed state, the inside of the guide cavity 2 is in a negative pressure state during the operation of the transmission blade 101. At this time, the high-temperature gas inside the first storage box 12 and the second storage box 13 will enter the inside of the gas collection box 5 through the guide cavity 2, thereby achieving the circulation of high-temperature gas inside the drying box. When the humidity sensor 15 detects that the high-temperature gas inside the gas collection box 5 contains a lot of water vapor, the humidity sensor 15 can transmit the detection information to the monitoring and control system 16. The monitoring and control system 16 starts the exhaust pump 1, thereby achieving the discharge of high-temperature gas containing water vapor from the inside of the gas collection box 5. Then, air can be injected back into the inside of the gas collection box 5 through the air inlet 52.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
