Its core function is to reduce grain loss and preserve quality through mechanization, intelligentization, and environmental control. Existing grain storage equipment, such as the novel insulated silo disclosed in Chinese patent CN120211541A, includes a silo wall, which serves as the foundation of the entire silo and supports and supports other structural components; a silo roof, located at the top of the silo wall and with its bottom fitting flush with the top of the wall for use in conjunction with the wall; the silo wall comprises wall panels, side insulation layers, and side lining layers. The side insulation layers are located inside the wall panels, and the side lining layers are located inside the side insulation layers. The wall panels are made of galvanized steel, the side insulation layers are made of polyurethane foam, and the side lining layers are made of reinforced concrete.
[0003] The aforementioned grain storage equipment has the following defects in actual use:
[0004] Firstly, the fixed construction makes it impossible to move the equipment, making it difficult to adapt to the seasonal transportation needs of grain-producing areas;

[0006] Third, the loading and unloading process requires additional conveying equipment, which reduces the efficiency of the connection between the warehousing system and the logistics system and increases the time and cost of operation. Utility Model Content

[0113] Working principle and usage:
[0114] Step 1, Pre-setting:
[0115] Perform power supply debugging on this device.
[0116] The second step is to maintain a constant temperature and humidity:
[0117] Pressing the movement switch activates the PLC controller, which outputs a signal to servo motor 201. Servo motor 201 starts, driving the corresponding rollers to rotate, thus enabling the device to move and turn.
[0118] Move the device to the side of the pile of grain (such as rice, wheat, or beans) to be collected. Press the fixing switch; the PLC controller outputs a signal to the electro-hydraulic rod 202, which starts and fixes the storage bin in place.
[0119] Press the data acquisition switch, and the distance sensor module outputs a signal to the PLC controller. The PLC controller then outputs a signal to the screw feeder 301, the electric telescopic rod 1 302, and the electric telescopic rod 2 501.
[0120] Electric telescopic rod 302 drives telescopic tube 303 to move, so that one end of telescopic tube 303 is directly above the storage bin. Screw feeder 301 starts after a delay and transfers the grain into the storage bin. After full load, electric telescopic rod 302 drives telescopic tube 303 to reset, electric telescopic rod 501 starts, and drives saucer-shaped top cover structure 502 to move down and close the storage bin.
[0121] Temperature and humidity sensor module one and temperature and humidity sensor module two output signals to the PLC controller. The PLC controller outputs signals to the heating wire 504, the downward pressure fan 505, the spiral auger conveyor 506, the intake fan 601, the exhaust fan 603, and the stepper motor 604.
[0122] When the temperature and humidity do not meet the preset values and drying is required, if the external temperature and humidity are suitable, the stepper motor 604 opens the rotating gate, the air intake fan 601 starts, and the push rod motor 605 opens the air intake gate to dissipate moisture.
[0123] If the external temperature and humidity are not suitable, the push rod motor 503 starts, opens the movable gate, and the exhaust fan 603 starts; if the humidity inside the rice pile is too high, the screw conveyor 506 starts, slowly turning the grain upwards to achieve drying; the heating wire 504 and the downward pressure fan 505 start to accelerate drying and prevent mold and clumping.
[0124] When the temperature and humidity do not meet the preset values and cooling is required, if the external temperature and humidity are suitable, the heating element 504 and the down-pressure fan 505 will not start, and the rest is the same as above.
[0125] If the external temperature and humidity are unsuitable and worse than inside the storage chamber, the stepper motor 604 and the push rod motor 605 will not start; otherwise, the process is the same as the two processes described above.
[0126] The above steps correspond to the following scenarios:
[0127] Mode A: External ventilation and dehumidification mode
[0128] When the humidity inside the chamber is detected to be excessive and the external temperature and humidity are suitable (e.g., external humidity < set value and temperature < chamber temperature or within an acceptable range), the stepper motor 604 opens the rotating gate (opens the external circulation air inlet of the bottom plate).
[0129] a. Push rod motor 2605 opens the air inlet damper (opens the side wall air inlet).
[0130] b. Intake fan 601 starts (forces in dry external air).
[0131] c. Exhaust fan 603 starts (may be required, depending on the designed airflow path).
[0132] d. The heating element 504 is turned off.
[0133] e. The down-pressure fan 505 can be turned off or on (to promote airflow).
[0134] f. Screw 506 shut off (unless designed to assist in the distribution of grain through ventilation).
[0135] Mode B: External ventilation and cooling mode
[0136] When the temperature inside the chamber is detected to be too high and the temperature and humidity of the external environment are suitable (e.g., external temperature < internal temperature and external humidity < upper limit), the stepper motor 604 opens the rotating gate.
[0137] a. Push rod motor 2605 opens the air inlet damper.
[0138] b. Intake fan 601 starts.
[0139] c. Start exhaust fan 603 (may be required).
[0140] d. Heating element 504 must be turned off.
[0141] e. The down-draft fan 505 can be turned on (to promote airflow and heat dissipation).
[0142] f. Turn off the spiral auger 506 (unless designed for auxiliary heat dissipation).
[0143] Mode C: Internal forced circulation dehumidification / temperature control mode
[0144] When the temperature and humidity inside the chamber exceed the standard and the external environment is not suitable for ventilation (too high / too humid / too low), the stepper motor 604 will shut down the rotating gate (shut down the external circulation of the bottom plate).
[0145] a. Push rod motor 2605 closes the air inlet damper (closes the side wall air inlet).
[0146] b. Start the push rod motor 503 and open the movable gate (open the exhaust port of the top cover).
[0147] c. Exhaust fan 603 starts (expelling hot and humid air).
[0148] d. The 504 heating element should only be activated when dehumidification is needed (to heat the air and reduce relative humidity). It should not be activated when cooling is required.
[0149] e. The down-pressure fan 505 starts (to promote air circulation inside the chamber).
[0150] f. Start the screw conveyor 506 (slowly turn the grain to prevent localized damp heat and clumping, promote uniform evaporation of moisture, mainly for dehumidification, with limited effect on cooling).
[0151] The third step is to collect the grain.
[0152] Open the valve, press the grain dispensing switch, and the PLC controller will control the servo motor 401 to start, allowing the grain to flow out of the storage bin in an orderly manner.
[0153] Depending on the requirements, this device can be fixed indoors or to a pile to improve its earthquake and wind resistance. Simply press the fixing switch; the PLC controller outputs a signal to the electric hydraulic rod 202, which then activates to fix the storage compartment in the appropriate position.
[0154] Example 2: Based on Example 1, a rainproof curtain is added to the conical canopy 105 to improve the adaptability of the device.
