A microwave insect egg removing device for grains comprises: a feeding funnel at least a main microwave chamber body, which is located under the feeding funnel, a chamber formed to run through the main microwave chamber body, a plurality of coupling holes formed to radially run through the main microwave chamber body, in which any two of the coupling holes are not at the same altitude of the main microwave chamber body, and any two adjacent coupling holes are not diametrically opposite to each other two microwave interception devices, one of which is arranged between a lower end of the feeding funnel and an upper end of the main microwave chamber body, and another microwave interception device is arranged at a lower end of the main microwave chamber body and a plurality of microwave adjustment tube assemblies, which are set in the radial direction in the coupling holes of the main microwave chamber body and in communication with the chamber. The uniform arrangement of the coupling holes, in combination with microwave emission sources, allows for an insect egg removing operation in an omnidirectional manner.一種適用穀物的微波除蟲卵裝置,包含有:一注入漏斗;至少一微波主腔體,係位於注入漏斗下方,在微波主腔體上貫穿形成一腔室,在微波主腔體的徑向上貫穿形成有複數耦合孔,其中任兩耦合孔非在微波主腔體的同一高度上,且任兩相鄰的耦合孔呈非徑向相對;二微波截斷器,其一設置在注入漏斗下端與微波主腔體上端之間,另一微波截斷器設置在微波主腔體下端;以及複數微波調整管組件,係分別沿徑向設置在微波主腔體的耦合孔上並且與腔室相連通。耦合孔均勻排列方式配合微波發射源可全方位進行除蟲卵的作業。10‧‧‧微波主腔體100‧‧‧腔室101‧‧‧耦合孔20‧‧‧微波截斷器200‧‧‧穿孔21‧‧‧筒體22‧‧‧中心桿23‧‧‧葉片40‧‧‧注入漏斗50‧‧‧微波調整管組件
