Description

Technical Field

[0001] The utility model belongs to the technical field of radiation breeding, and particularly relates to a rotatable static irradiation placement rack. Background Art

[0002] Radiation breeding technology is a technology that uses rays to induce changes in the heredity of organisms and cultivates new excellent varieties through artificial selection. The genetic effect of radiation-induced mutation is that radiation can ionize and excite various molecules in organisms, leading to changes in the DNA molecular structure, resulting in gene mutations and chromosome aberrations. Under the action of ionizing radiation, the normal metabolism of organisms is disrupted, and the growth and development of organisms are severely inhibited, thereby causing changes in genetic factors and passing on new genetic factors to offspring.

[0003] Radiation breeding is to use radioactive rays (such as x-rays, γ-rays or neutron rays, etc.) to irradiate the seeds or plants of crops, and can also irradiate in vitro tissues and cells to cause changes inside them. Some of these changes can be inherited to the next generation, thus resulting in genetic variations. Through artificial selection, new varieties can be cultivated. Radiation breeding technology is mainly used for plants. The radiation treatment methods include external irradiation and internal irradiation. External irradiation treatment is to send the seeds or plants into the irradiation chamber for irradiation, or plant them in a cobalt garden for chronic irradiation throughout the growth period, such as using γ-ray, x-ray radiation, etc.

[0004] Rays are harmful to both animals and plants. When organisms absorb high-energy x-rays, γ-rays or neutron rays, various changes in chromosomes within cells are caused. However, if the changes are large, it will lead to death. If the changes are not too large, it may show changes in the heredity of plants, that is, mutations occur, which provides conditions for breeding. Therefore, if used properly, not only will it not harm crops, but radiation can also be used for breeding.

[0005] From the perspective of breeding requirements, the more changes in crops, the greater the hope of breeding new varieties. Here, a contradiction arises. If the dose is low, the variation is small; if the dose is high, the death rate is high. Therefore, many people think that it is more appropriate to treat plants with the semi-lethal dose. That is to say, the dose used should be able to make about half of the plants survive and the other half die, so as to ensure that a certain number of plants survive and a considerable number of plants mutate.

[0006] In general, the irradiation dose in radiation breeding is relatively low, and there are high requirements for dose control. If the dose is too large, the crops are likely to die, and if the dose is too low, there will be few mutations. Industrial irradiation devices generally have a large source activity. When irradiating in the conventional dynamic mode, the irradiation dose cannot be controlled within the dose range of radiation breeding. Therefore, only the static mode can be used for irradiation. The current static irradiation method is to stop the irradiation device and lower the source, then take the crops that need radiation breeding to a fixed position in the irradiation room for irradiation. After the irradiation is completed according to the set time, the irradiation device is stopped and the source is lowered to take out the crops. The schematic top view of the spreader in the irradiation room is as follows Figure 1 as shown. The crops for radiation breeding can be placed outside the spreader stop position ( Figure 1 within the square of the irradiation room shown) and in a position that does not affect the normal operation of the spreader. This method requires suspending the operation of the irradiation room, taking the crops that need radiation breeding to a fixed position in the irradiation room and then starting it again. Taking out also requires suspending the operation of the irradiation room, stopping the irradiation device and lowering the source to take out the crops. This process is time-consuming and laborious, and it is necessary to suspend the original production progress, affecting production efficiency.

[0007] In view of this, there is a need for a method that can put the crops for radiation breeding into the irradiation room without suspending the operation of the irradiation room, and at the same time can take out the crops from the irradiation room without suspending the operation of the irradiation room after the irradiation is completed. Summary of the Utility Model

[0012] Preferably, a hub is provided above the static irradiation track at the entrance of the irradiation chamber. The hub is cylindrical and is rotatably fixed to the ground through a bracket. The control line of the rotating motor extends through the inner bottom of the static irradiation track and winds around the hub. A torsion spring is provided on the rotating shaft of the hub.

[0013] Preferably, scale marks are provided on the control line to determine the distance between the carrier trolley and the hub. Combining with the length of the static irradiation track, the position of the carrier trolley in the irradiation chamber can be inferred.

The following describes the embodiments according to the overall structure of the present utility model.

[0034] As Figure 1-2 shown, this embodiment provides a rotatable static irradiation placement rack, including an irradiation chamber 1, a cobalt source plate 2, and a spreader stop track 3. The irradiation chamber 1 is provided with an inlet 101 and an outlet 102. The cobalt source plate 2 is arranged in the middle of the irradiation chamber 1. The spreader stop track 3 passes through the irradiation chamber 1 from the inlet 101 and winds around in the irradiation chamber 1 for several circles, and then extends from the outlet 102 to the outside of the irradiation chamber 1. This device also includes a static irradiation track 4 and a load-carrying trolley 5. The static irradiation track 4 is arranged on the ground and enters the irradiation chamber 1 from the inlet 101 at a position other than the spreader stop track 3. The load-carrying trolley 5 can move on the static irradiation track 4 through a moving unit 7, and a cultivated plant 6 is placed above the load-carrying trolley 5.

[0035] During use, place the cultivated plant 6 above the carrier trolley 5, and then start the carrier trolley 5 to enter the position of the non-hoist collective stop track 3 in the irradiation chamber 1 along the static irradiation track 4 for irradiation. After the irradiation is completed, start the carrier trolley 5 to return.

[0036] The static irradiation track 4 is in a "U" shape. The moving unit 7 includes moving wheels 701, guide wheels 702 and a driving motor 703. The moving wheels 701 are divided into two groups, front and back, and are arranged below the carrier trolley 5. The driving motor 703 is connected to one group of moving wheels 701. There are two guide wheels 702, which are respectively arranged on both sides in front of the carrier trolley 5. The circumference of the guide wheel 702 is tangent to the side surface of the static irradiation track 4.

[0037] During use, the driving motor 703 drives the moving wheels 701 to rotate, so that the carrier trolley 5 moves on the static irradiation track 4. The circumference of the guide wheel 702 is tangent to the side surface of the static irradiation track 4. When the static irradiation track 4 turns, the carrier trolley 5 can turn by the relative rotation of the guide wheel 702 and the side surface of the static irradiation track 4. The static irradiation track 4 enters the position of the non-hoist collective stop track 3 in the irradiation chamber 1 from the entrance 101 ( Figure 1 shown in the square of the irradiation chamber 1) to receive irradiation. After the irradiation is completed, start the carrier trolley 5 to return.

[0038] The carrier trolley 5 further includes a bottom plate 704, a rotating motor 705 and a loading platform 706. The bottom plate 704 is connected to the moving unit 7. A rotating motor 705 is fixedly connected above the bottom plate 704. The output end of the rotating motor 705 faces upward and is fixedly connected to the loading platform 706. The control line 707 of the rotating motor 705 extends outside the irradiation chamber 1 through the inner bottom of the static irradiation track 4.

[0039] During use, move the carrier trolley 5 into the irradiation chamber 1. During the irradiation process, place the cultivated plant 6 on one side of the source plate. The dose on the side facing the cobalt source plate 2 is relatively high. If a more uniform irradiation dose is desired, it is necessary to regularly rotate the side of the cultivated plant 6 originally facing the source to face away from the source. When rotating, through the control line 707 of the rotating motor 705, an instruction is issued externally, and the rotating motor 705 rotates 180 degrees, so that the side originally facing the cobalt source plate 2 faces away from the cobalt source plate 2, making the irradiation dose of the cultivated plant 6 more uniform.

[0040] As Figure 2-4Since one end of the control line 707 of the rotating motor 705 needs to enter the irradiation chamber 1 with the carrier 5, the length of the control line 707 of the rotating motor 705 will be set according to the length of the track. When the carrier 5 is located at the entrance 101, the control line 707 needs to be arranged. Therefore, a hub 708 is arranged above the static irradiation track 4 at the entrance 101 of the irradiation chamber 1. The hub 708 is cylindrical and is rotatably fixed to the ground by a bracket 709. The control line 707 of the rotating motor 705 extends through the inner bottom of the static irradiation track 4 and is wound around the hub 708. A coil spring 710 is provided on the rotating shaft of the hub 708. When in use, the carrier 5 enters the irradiation chamber 1 from the entrance 101, and the hub 708 rotates with the pulling force of the carrier 5. When the carrier 5 returns, the hub 708 will rotate in the opposite direction under the action of the coil spring 710 to recover the control line 707 of the rotating motor 705. In addition to the control line 707 of the rotating motor 705, the control line 707 of the driving motor 703 mentioned above can also adopt this method.

[0041] The control line 707 is provided with a scale mark to record the distance from the carrier 5 to the mark, which is used to determine the distance between the carrier 5 and the hub 708. Combined with the length of the static irradiation track 4, the position of the carrier 5 in the irradiation room can be inferred, which is used to position the carrier 5.

[0042] A timing module 8 is disposed outside the irradiation chamber 1 . The timing module 8 is electrically connected to the driving motor 703 . The timing module 8 includes a display 801 and an input button 802 .

[0043] When in use, according to the type of the plant 6 to be cultivated, the start-up time of the rotating motor 705 and the driving motor 703 is set, and the input is input through the input button 802. The required time and the remaining time are displayed on the display 801. When the set time is up, the rotating motor 705 will be controlled to rotate or the driving motor 703 will be controlled to return the object-carrying trolley 5. The electrical connection method of the timing module 8 and the driving motor 703 can be consistent with the above-mentioned control line 707 of the rotating motor 705 and the external connection method. This method does not require long-term monitoring by personnel, saving human resources.

[0044] like Figure 1 Three rows of hangers are parked on both sides of the cobalt source plate 2. The bottom of the hanger is about 35 cm above the ground and the height is about 2 meters. That is, after the hangers are parked, most of the radiation energy at the height of 35 to 235 cm has been blocked, and only the bottom 0 to 35 cm is unblocked and radiation can be irradiated. Therefore, the total height of the static irradiation track 4, the cargo trolley 5 and the breeding plants 6 is no more than 35 cm, and this space can be used without being affected by normal hangers.

[0045] like Figure 3, there are also dosimeter placement grooves 9 provided at 6 places on the breeding plants, and dosimeters are placed in the dosimeter placement grooves 9. As Figure 5 , the dosimeter is loaded in a 2-ml Type B breakable glass ampoule bottle, and the outside of the ampoule bottle is wrapped with a protective shell. The diameter of the protective shell is about 2 cm, and the height is about 7.5 cm ( Figure 5 the ampoule bottle is on the left and the protective shell is on the right).

[0046] In order to make better use of the space in the irradiation chamber 1, the static irradiation track 4 extends in the irradiation chamber 1 to each non-lifting tool set stop track 3 position, and the position where the load-carrying trolley 5 stays can be adjusted as needed.

[0047] The foregoing description of the specific exemplary embodiments of the present invention is for the purpose of illustration and exemplification. These descriptions are not intended to limit the present invention to the precise form disclosed, and obviously, many changes and variations can be made according to the above teachings. Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention, and they are not limitations of the present invention.
