[0002] Special buildings for storing grain mainly include warehouses, cargo yards (or drying yards) and facilities for metering, transportation, stacking, cleaning, loading and unloading, ventilation, drying, etc., and are equipped with instruments for measuring, sampling, inspection and testing.

[0003] When ventilating the existing storage bin, a fan is required to be used in conjunction with a filter plate and a ventilation box to filter dust in the external air. However, when inhaled for a long time, dust is easily accumulated on the filter plate, which in turn blocks the pores of the filter plate, causing the incoming wind flow to gradually decrease, reducing the ventilation efficiency. In rainy weather or humid environments, since the air inlet of the ventilation box is open, rain or humid airflow can easily penetrate into it, making it easy for the fan and filter plate to absorb rain or humid airflow, thereby causing varying degrees of damage to the fan and filter plate, making it inconvenient to use. Therefore, we have proposed a feed storage bin ventilation equipment with functions that are easy to protect and use, which is urgently needed to be developed. Utility Model Content
