[0017] 1. The utility model sets a temperature control mechanism. First, air is injected into the inner cavity of the cold air box through the air inlet pipe. Then, the cold air box cools the air. Subsequently, the cold air box injects the cold air into the inner cavity of the cold air pipe. Then, the cold air enters the interior of the connecting pipe again, and the cold air in the connecting pipe and the cold air pipe is injected into the inner cavity of the granary body through the ventilation slots. At the same time, the input end of the fixed fan generates suction, and these suctions are conducted to the dust suction pipe through the dust suction box, and the dust suction pipe sucks the cold air and dust in the granary.

[0018] 2. The utility model sets a connecting pipe, which can make the connecting pipe inserted into the grain to avoid the situation that the temperature inside the grain is too high to be cooled due to stacking, resulting in spoilage of the grain inside the grain pile. By setting the clamping block, it is convenient to disassemble and clean the filter screen, avoiding that after long-term use, the surface of the filter screen is covered with more dust, thus affecting the dust filtration effect. By setting the sliding rod, it is convenient to take out the dust collection tank, thereby improving the cleaning work of the dust in the inner cavity of the dust collection tank. By setting the L-shaped bracket, it can support the cold air pipe, avoiding that after long-term use, the cold air pipe falls off from the surface of the cold air box due to its own weight, thus affecting the cooling work in the inner cavity of the granary body. By setting the filter cloth sleeve, since the connecting pipe is embedded in the grain pile, it can filter the ventilation slots on the surface of the connecting pipe to prevent the grain from entering the inner cavity of the connecting pipe through the ventilation slots, thus affecting the normal cooling work. By setting the temperature induction probe and the temperature display panel, the temperature in the granary body can be detected in real time, facilitating timely cooling of the temperature in the inner cavity of the granary body. By setting the fixing bolts, the cover plate can be disassembled, facilitating the removal of the filter screen and the dust collection tank in the inner cavity of the dust suction box.

[0033] By setting the temperature control mechanism 2, first, air is injected into the inner cavity of the cold air box 201 through the air inlet pipe 202. Subsequently, the cold air box 201 cools the air. Then, the cold air box 201 injects the cold air into the inner cavity of the cold air pipe 203. Then, the cold air enters the inside of the connecting pipe 205 again, and the cold air in the connecting pipe 205 and the cold air pipe 203 is injected into the inner cavity of the granary body 1 through the ventilation grooves 204.

By providing the filter cloth sleeve 217, since the connecting pipes 205 are buried in the grain pile, the ventilation grooves 204 on the surface of the connecting pipes 205 can be filtered, preventing the grain from entering the inner cavity of the connecting pipes 205 through the ventilation grooves 204, which affects the normal cooling work. By providing the temperature induction probe 215 and the temperature display panel 216, the temperature inside the grain storage bin body 1 can be detected in real time, facilitating timely cooling of the temperature inside the inner cavity of the grain storage bin body 1.

These dusts enter the inner cavity of the dust suction box 206. Due to the filtration of the filter screen 210, the dusts fall into the inner cavity of the dust collection groove 211, completing the dust collection work. At the same time, the output end of the fixed blower 208 injects the extracted cold air into the inner cavity of the cold air box 201 again, so that the cold air can circulate.
