AI Technical Summary
When the grain is stored in a circulating fumigation device, the density and porosity inside the grain pile are uneven, which makes it difficult for the fumigant gas to penetrate, resulting in incomplete insecticide and reduced insect prevention effect.
The worm and worm gear system is driven by the power parts to drive the rotating rod and spiral blades to rotate, thereby lifting the grains and repeatedly moving them through the toggle parts to separate the tightly packed grains and enhance the penetration effect of the fumigation gas.
The penetration capacity of fumigant gas in grains is improved, and the insect prevention effect of the circulating fumigation device is enhanced.

[0002] Cereals refer to the seeds or fruits of edible grain crops, including cereals, beans, and potatoes. During the storage of grains, in order to prevent and control storage pests, it is usually necessary to adopt a circulating fumigation method to achieve the purpose of killing insects. That is, fumigant gas is introduced into the granary through the circulating pipes, fans, applicators, diffusers and other equipment installed in the granary, and the toxic gas is used to kill the pests and their eggs in the stored grain, thereby achieving the effect of preventing and killing insects.
[0003] The currently commonly used circulation fumigation method is to lay pipes and valves for discharging fumigant gas inside the grain pile. The pipes are fixed to the warehouse wall, and fumigant gas is applied to the grain through the pipes and diffusers, thereby achieving the effect of preventing and killing insects.
[0004] According to the above, there is a grain storage circulating fumigation device, which still has shortcomings in actual use. The most obvious one is that when the grain is stacked, the density and porosity inside the grain pile may be uneven. The tight stacking may make it difficult for the fumigation gas to penetrate, resulting in incomplete insecticide, which reduces the insect prevention effect of the circulating fumigation device. For this reason, we propose a grain storage circulating fumigation device. Utility Model Content
