Embodiments of the technical scheme of the present invention will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present invention, and thus are merely examples, and are not intended to limit the scope of the present invention.
An example is substantially as shown in figures 1 to 8:
example 1:
as shown in fig. 1-8, the full-automatic electron accelerator biological irradiation breeding mutagenesis device provided by the embodiment can solve the problem that the mutagenesis breeding energy is adjustable and controllable.
The invention provides a full-automatic electron accelerator biological irradiation breeding mutagenesis device, which comprises: a fixed box 1; an electron accelerator 2, the electron accelerator 2 is installed in the fixed box 1, and the electron accelerator 2 comprises a power supply modulator 21, an accelerator head 22 and a water cooling unit 23; the power modulator 21 is electrically connected with the accelerator handpiece 22; the water cooling unit 23 is installed at one side of the accelerator head 22; the power modulator 21 is used for converting industrial alternating current into electrically controlled high-voltage pulse current; the accelerator handpiece 22 includes an accelerator 221 and an acceleration tube 222; the accelerator 221 is electrically connected to the power modulator 21; the water cooling unit 23 comprises a water cooling sleeve 231, and the water cooling sleeve 231 is communicated with an external water source; the accelerating tube 222 is installed in the water-cooling jacket 231; a collimator-equalizer disposed within the stationary box 1, the collimator-equalizer being located below the accelerating tube 222; the collimation-equalizer is used for correcting the non-uniformity of the X-rays; a multi-leaf collimator system 4, the multi-leaf collimator system 4 being arranged below the collimator-equalizer; the multi-leaf grating system 4 is used for conducting space division guiding on the irradiation dose corrected by the collimation-equalizer; and a conveying mechanism 5, the conveying mechanism 5 comprising a conveying line 51 and a tray 52; the trays 52 are arranged on the conveying line 51 at least one place and are uniformly distributed along the direction of the conveying line 51; the conveying line 51 is in a shape of a Chinese character 'hui'; the tray 52 is used for being placed on seeds to be bred and is positioned below the multi-leaf grating system 4; the fixed box 1 is disposed on the conveying mechanism 5 and above the conveying line 51. In practical application, the adopted electron accelerator 2 is the linear electron accelerator 2, so that the problems of adjustable and controllable mutation breeding energy and over-high seed mortality and insufficient mutation frequency caused by uncontrollable irradiation dose can be well solved. And the radiation is generated without a radioactive substance source, so that the radiation is safe and reliable to use, and the influence on the environment and personnel is safe and controllable. Meanwhile, the automatic transmission mechanism 5 is adopted, so that manual operation is greatly reduced, and the efficiency can be effectively improved.
Meanwhile, the electron accelerator 2 mainly comprises a power supply modulator 21, an accelerator head 22 and a water cooling unit 23. The power modulator 21 provides high-voltage and control signals for the accelerator head 22, and the water cooling unit 23 provides cooling for an accelerating tube 222 of the accelerator head 22 to ensure that the accelerator head 22 works in a stable state.
The power modulator 21 converts the industrial alternating current into high voltage pulses that are electrically controlled by an internal ac-dc-ac rectification inversion process to power the microwave power source 103 in the accelerator handpiece 22. The microwave power source 103 generates a high-power microwave signal, the microwave power feeds electrons into the accelerating tube 222 through the waveguide device 104, and after the microwaves generated by the microwave power source are fed into the accelerating tube 222, a forward wave and a backward wave are formed in the accelerating tube 222, and the forward wave and the backward wave are overlapped to form a standing wave field. At the same time, the electron gun 105 controls the electron output, the electrons interact with the axial standing wave electric field in the accelerating tube 222, interact with the radio frequency accelerating electric field, and absorb energy therefrom, so that the energy of the electrons is increased. Electrons are continuously accelerated in the standing wave field and when the final energy reaches the target energy, the electrons generate continuous spectrum X-rays in the accelerator head 22 accelerating terminal accelerator tube 222.
Limited by the bremsstrahlung principle, the number and energy of X-ray photons in different directions of radiation after electron beam targeting are different, i.e. the dose rate exhibits directional non-uniformity. The radiation exiting the accelerator handpiece 22 has different dose rates over different angular ranges, and the irradiation dose can directly affect the breeding effect. The collimation-leveling device 3 is mainly used for correcting the non-uniformity of the X-rays and is used for improving the influence of inaccurate irradiation dose on the breeding effect. And the whole control operation is carried out by adopting an electric control mode, wherein the PLC is used as a central control unit, the PLC is remotely transmitted by upper computer set software to control the work of the PLC, and other auxiliary electric elements realize signal interaction with the PLC through a dry node.

In practice, the design can lift the base 531 and the components mounted on the base 531, thereby facilitating the turning of the tray 52.
In this embodiment, the lifting and traversing mechanism 53 further includes a transmission belt 533 and a motor 534; the motor 534 is mounted on the base 531, the transmission belt 533 is mounted on two sides of the base 531, and the transmission belt 533 is in transmission connection with the motor 534. In practical application, the transmission belt 533 in the design has two positions and is horizontally symmetrical; unbalanced rocking of the tray 52 at the time of steering is greatly reduced. Meanwhile, in the design, a motor 534 drives a transmission shaft, a transmission wheel and the like to drive, and the transmission belts 533 at the two ends rotate; because the drive transmission belt 533 in this design is a conventional design, it will not be described in detail here; the rotating drive pulley will cause the pallet 52 to turn, because in design the drive direction of the drive pulley is perpendicular to the direction of movement of the conveyor line 51; thus, the conveyor belt 533 will contact the tray 52 by the pushing up of the first cylinder 532; the transfer belt 533 then rotates the tray 52 to be turned.
In this embodiment, the conveying mechanism 5 further includes a stopping mechanism 54, and the stopping mechanism 54 is mounted on the conveying line 51 and is located at the rear of the lifting and traversing mechanism 53; the stop mechanism 54 comprises a fixed plate 541, a fixed frame 542 and a second cylinder 543; the fixing plate 541 is installed in the conveying line 51, and the fixing plate 541 has a fixing through slot 101 and a fixing hole 102; the fixing holes 102 are arranged everywhere, and the second air cylinders 543 are fixedly arranged at the fixing through grooves 101 through the fixing holes 102; the fixing frame 542 is fixedly installed on the fixing through groove 101. In practice, the purpose of this design is to achieve a blocking of the further movement of the pallet 52 on the conveyor line 51, and wherein the fixing plate 541 is able to effectively fix the design.
