The micro refrigerator can be selected for refrigeration, such as Alpicool (-20-20deg.C, 425×320×255 mm) 3 The air conditioner is characterized in that 12V and 24V (220V are optional), the machine body is arranged in the lower half area of the cabinet body, the cold air passes through the inner protection baffle plate by using the serpentine bent pipe and is introduced into the upper insect containing box area of the cabinet body, and if the air conditioner needs to be heated, the electric heater can be used for introducing hot air at the same time. The humidity regulator 305 corresponds to a mini dehumidifier and includes a humidity detection and dehumidification device, such as CS10E (220V, 245X 145X 375 mm) 3 ) The detection probe and the moisture absorption tube are arranged on the same. The atmosphere regulator 306 is a device that replaces air with nitrogen or argon or carbon dioxide to achieve a low oxygen environment, including a gas source, detection and control valves. A tank filled with nitrogen, argon or carbon dioxide is used as a Gas source, and the Gas concentration is detected by a Gas sensor, such as an MS400S Gas detector, which is arranged at the upper half part of the cabinet body and is close to the insect containing box, so as to control the opening and closing of the ventilation valve. The stirring fan 307 can uniformly mix the temperature, humidity and atmosphere of the upper half part of the cabinet body, and ensures that the insects in the box are in the same temperature, humidity and air environment condition through 4 surface overturning of the insect containing box. The sub-controller 309 may set and coordinate all irradiation process parameters and action instructions for cooling, dehumidification, ventilation, flipping, irradiation time, travel speed, etc.
The transduction cover plate 310 at the top of the irradiation bearing cabinet 301 is made of aluminum or irradiation-resistant polymer material, has the thickness of 1-10mm, has little absorption on the radiation energy and has the functions of sealing and heat insulation. Because the energy spectrum distribution of the X-rays output by the ray generator is uneven, the energy conversion cover plates with different thicknesses and materials are adopted for filtering, and the irradiated insects can be subjected to radiation treatment with uniform energy.
The flipping system 303 within the irradiation carrier 301 is a key component to reduce the body irradiation dose non-uniformity (non-uniformity = maximum absorbed dose/minimum absorbed dose). The flipping system 303 is preferably disposed at the bottom and one side of the insect container. As shown in fig. 2 and 3, above the insect containing box is a transduction cover plate 310, and a turnover system 303 is arranged at the left side, the right side and the lower side.

The overturning of the insect containing box 302 is controlled by electromagnetism in two steps: when the sub-controller 309 sends out a turning command, the vertical turning magnet B3031 starts to generate traction suction to the adsorption iron plate 3032, the insect-holding box is sucked to the universal wheel 3033, and a 180-degree turning action is executed by the magnetic control clockwise by taking the X axis as the center, and the insect-holding box automatically falls down and resets after finishing the turning action; and secondly, similarly, the horizontal overturning magnet D3034, the adsorption iron plate 3035 and the universal wheels 3036 finish the overturning action of 180 degrees by taking the Z axis as the center. Any overturning actions of 60, 90, 120 degrees and the like can be executed according to the requirement. The flipping system is typically arranged in 2 pairs, but may also be arranged in 4 peer-to-peer pairs as desired.

The box cover 3021 is made of aluminum or radiation-resistant polymer material, and at least 20 air and moisture holes 3022 are formed in each surface of the box body and the box cover. The ventilation and moisture permeability holes 3022 are micro small holes with phi less than 1 mm. When the insect body is filled, a large amount of respiratory heat and carbon dioxide are generated, and the insect body is dispersed out through micropores through overturning and shaking, cooling in the cavity, dehumidifying and atmosphere adjustment. The gauze interlayer 3023 may be a single-layer or double-layer medical gauze, and is provided with 1 to more parts in the horizontal and vertical directions, so that the insect-containing box is divided into 4 or more regions, which not only prevents soft insect bodies from being injured by mutual extrusion and overturning, but also further disperses heat and atmosphere. The attracting iron plates 3032 and 3035 are ferromagnetic materialsThe material has strong suction of 4-10 kg. The insect containing box is generally arranged as 2 pairs, and can also be arranged as 4 pairs of pairs according to the requirement. Each length x width x height=300 x 500 x 200mm 3 The shape silk-like drum shape is rotatable when being turned over conveniently.

The main track 401 is annular, and two ends of the auxiliary track 402 are respectively connected to different positions of the main track 401.
Intermittent irradiation process: after receiving the instruction of the main controller, the sub-controller drives the traveling card wheel 308 to carry the irradiation carrying system cabinet 3 to the I-preparation area along the main track 401 to wait for irradiation. After the irradiation of the current position is finished, the protection entrance door 5 and the traveling clamping wheel 308 are started to carry the system cabinet to continuously move forward from the outer rail (outside the box body) to enter the II-irradiation area of the inner rail (inside the box body), at the moment, the protection entrance door is rapidly closed, the ray generator 1 immediately emits rays to start irradiating the insects in the cabinet, after the irradiation is finished, the rays are stopped, the protection exit door is started, the system cabinet is driven out of the inner rail to enter the III-recovery area of the outer rail, and the insects slowly recover to the normal growth environment state. If there are more recovery bins than subsequent irradiation bins, the excess bins may be deposited in the secondary track 402.
Continuous irradiation process: the radiation generator continuously emits radiation. In order to meet the protection requirement, a movable protection wall A/B403 (inlet) and a movable protection wall C/D404 (outlet) are respectively additionally arranged outside the protection exit and the protection entrance. Each movable protective wall is formed by,Two L-shaped blocks are spliced to form the model. Before the entrance of the protective door is opened, the protective door is pulled open>The protective wall makes the system cabinet wait before entering the protective door, and then immediately closes to form the [ type shielding body ]. After the front irradiation is finished, the irradiation bearing system cabinet 3 enters the irradiation cavity 301, and rays leaked in the opening process of the protective door are completely shielded by the [ type protective wall ]. The outlet operates in reverse. The movable protective wall is an auxiliary facility. In order to save the cost, an aluminum alloy outer layer sleeve can be adopted, and the inside is filled with sand or soil or concrete and other fine materials with certain thickness to compact so as to meet the protection requirement.
