The transduction cover plate 310 on the top of the irradiation bearing cabinet body 301 is made of aluminum or an irradiation-resistant high polymer material, is 1-10mm thick, needs to absorb little radiation energy and has the functions of sealing and heat insulation. Because the X-ray energy spectrum distribution output by the ray generator is uneven, the energy conversion cover plates with different thicknesses and materials are adopted for filtering, and the irradiation treatment of uniform energy received by the irradiated insect body can be realized.
The turnover system 303 in the radiation carrying cabinet 301 is a key component for reducing nonuniformity (maximum absorbed dose/minimum absorbed dose) of radiation dose of the worm. The flipping system 303 is preferably disposed at the bottom and one side of the insect-holding box. As shown in fig. 2 and 3, the transduction cover plate 310 is arranged above the insect containing box, and the turnover system 303 is arranged on the left side, the right side and the lower side.

The overturning of the insect containing box 302 is controlled by electromagnetic, and comprises two steps: firstly, when the sub-controller 309 sends a turning instruction, the vertical turning magnet B3031 starts to generate a traction suction force on the adsorption iron plate 3032, tightly sucks the insect containing box to the universal wheel 3033, executes 180-degree turning action by taking an X axis as a center in a clockwise direction through magnetic control, and automatically falls down and resets after the turning action is finished; and in the second step, similarly, the magnet D3034, the adsorption iron plate 3035 and the universal wheel 3036 are horizontally turned over to perform 180-degree turning action by taking the Z axis as the center. Any turning action of 60, 90, 120 degrees and the like can be executed according to the requirement. The roll-over system is generally set to 2 pairs, and can also be set to 4 pairs or more as required.

After the worm body is full, a large amount of respiratory heat and carbon dioxide are generated, and the worm body is turned, shaken, cooled in the cavity, dehumidified and adjusted in atmosphere and diffused out through the micropores. The gauze interlayer 3023 can be a single-layer or double-layer medical gauze, and is provided with 1 to more pieces of transverse and vertical medical gauze, so that the insect containing box is divided into 4 regions or multiple regions, thereby preventing soft insect bodies from being extruded and overturned to be injured, and further dispersing heat and atmosphere. The adsorbing iron plates 3032 and 3035 are made of ferromagnetic materials and have strong suction force of 4-10 kg. The insect containing boxes are generally arranged into 2 pairs, and can also be arranged into 4 pairs of more than one pairs according to requirements.
