Description

Technical Field

[0001] This invention relates to the field of tomato breeding technology, specifically a carbon dioxide-based anther preservation device for tomato breeding. Background Technology

[0002] Tomato hybridization breeding is a method that uses materials with different desirable traits in tomatoes as male and female parents, respectively, to produce new seeds through pollination and hybridization. These seeds are then selected and cultivated to obtain new varieties. The anther is the male reproductive organ of a flower, composed of pollen sacs. Pollen grains are produced within the pollen sacs, which split open upon maturity to release the pollen. While the anther itself is not a drug, the pollen it contains is sometimes used for medicinal or pollination purposes; therefore, proper storage of anthers is particularly important.

[0003] Before actual breeding, anthers need to be stored in a low-temperature and dry environment. Dry ice is generally used to achieve the purpose of low-temperature preservation. However, the traditional storage method is to place the anthers and dry ice in the same space. The dry ice sublimates and absorbs heat to lower the temperature. Although this method can achieve low-temperature preservation, the dry ice raw material is consumed too quickly, the temperature inside the storage box is too low, resulting in energy waste. Moreover, the low temperature also has an adverse effect on the pollen. The device cannot flexibly adjust the storage temperature according to the actual use environment inside the storage box, resulting in poor flexibility and low practicality. Summary of the Invention

[0012] As a preferred embodiment of the present invention, the air intake assembly includes a sealing plate rotatably disposed inside the air intake head, a limiting block fixedly connected inside the air intake head on one side of the sealing plate, and a telescopic member fixedly connected between the sealing plate and the inner wall of the air intake head.

[0013] As a preferred embodiment of the present invention, the transmission assembly includes a mounting rod, which is fixedly disposed on one side of the bottom wall of the storage box. A transmission gear is rotatably connected to one side of the mounting rod. A gear is fixedly connected to the side wall of the pneumatic telescopic cylinder on one side of the transmission gear. The gear meshes with the transmission gear. A drive wheel is rotatably connected to the side wall of the mounting rod on the axial side of the transmission gear. The shaft of the drive wheel is fixedly connected to the end of the shaft of the transmission wheel. The transmission wheel is rotatably connected to the outer wall of the storage box on the axial side of the rotating column. The transmission wheel and the drive wheel are connected in a transmission connection.

[0014] As a preferred embodiment of the present invention, the inspection-type cooling assembly includes a dry ice box disposed below the mounting plate, an air pump disposed above the mounting plate, an adjusting screw and a bearing column disposed between the protective plates on both sides of the air pump, mounting arms fixedly connected to both sides of the air pump, one mounting arm being threadedly connected to the adjusting screw and the other mounting arm being slidably connected to the bearing column, an air transmission pipe being fixedly connected to the air inlet end of the air pump, the air transmission pipe passing through the mounting plate and communicating with the dry ice box, an adjusting motor being fixedly connected to the side wall of the protective plate on one side of the adjusting screw, and the output shaft end of the adjusting motor being fixedly connected to the adjusting screw.

[0015] As a preferred embodiment of the present invention, the air outlet of the air pump is fixedly connected to the air outlet head, and movable grooves are opened on both sides of the air outlet head. A reset member is fixedly connected to the inner wall of the movable groove, and a piston cylinder is fixedly connected to one side of the reset member. An air transmission cylinder is slidably installed through the side wall of the piston cylinder, and an air transmission groove is opened on the air transmission cylinder. The air transmission cylinder is fixedly installed in the movable groove and communicates with the air outlet head.

[0016] This invention has the following advantages: The anthers are stored in a storage box. Under the action of a regulating motor, the regulating screw intermittently rotates forward and backward, which in turn drives the air outlet on the air pump to move laterally back and forth via the mounting arm. A temperature sensor monitors the temperature inside the storage box. When the temperature inside the storage box exceeds the standard storage temperature, it indicates that cooling is required. At this time, the temperature sensor transmits the information about the temperature increase to a temperature sensor, which then causes the thermal spring to extend, driving the rotating arm to rotate. The rotating arm drives the conductive rod to rise, and the conductive rod contacts the through-point rod. The power supply is electrically connected to the electric telescopic rod, which drives the valve rod above the piston rod to move. The valve port corresponds to the flow channel, and the venting groove moves into the valve cylinder. Under the action of the air supply pump, the gas is pushed into the pneumatic telescopic cylinder through the telescopic pipe. The pneumatic telescopic cylinder extends, thereby driving the lower air inlet head to move down. At this time, the air outlet head will contact the lower air inlet head during the reciprocating lateral movement. The piston cylinder on the air outlet head moves into the movable groove, so that the piston cylinder is connected to the air transmission cylinder. Then, under the action of the air pump, the gas is transmitted into the air transmission cylinder through the air outlet head and the air inlet head, and finally sprayed into the storage box through the air outlet. In this process, the air outlet head will drive the air inlet head to move laterally, so that the air outlet can move laterally, spraying the cold air evenly into the storage box to achieve rapid cooling of its interior.

[0017] Simultaneously, during the movement of the air outlet, a side gear rod moves laterally, which in turn drives a rotating column on one side of the drive wheel to rotate via the transmission gear and drive wheel. The rotating column drives the guide vane to rotate, causing the cold air inside the storage box to flow evenly, achieving rapid cooling of the storage box. When the temperature drops to a suitable value, the temperature of the thermal spring decreases and resets, causing the electric telescopic rod to lose power and move the valve rod downward. At this time, the pneumatic telescopic cylinder also resets, causing the air inlet head to rise. The air inlet head separates from the air outlet head, and the piston cylinder inside the air outlet head resets, preventing the low-temperature gas from flowing out. The above process is repeated. The device can flexibly adjust the temperature according to the actual temperature changes inside the storage box. When the temperature is within the acceptable range, cooling is not performed. While ensuring that the temperature inside the storage box is within the standard value, the consumption of dry ice is reduced, resulting in lower energy consumption and better economy. At the same time, it can prevent the adverse effects of excessively low storage temperature on the anthers, resulting in better performance. Attached Figure Description

[0035] The valve assembly includes a valve rod 37 that is slidably disposed on the valve cylinder 36. The valve rod 37 has a valve port 38 and a venting groove 59.

In its natural state, the outlet of the venting groove 59 is located outside the valve cylinder 36. In this case, the gas supplied by the air pump 35 will flow out from the venting groove 59. When the piston rod 40 drives the valve rod 37 to rise, the venting groove 59 moves into the valve cylinder 36. At this time, the valve port 38 corresponds to the guide channel 39, and the venting groove 59 no longer vents gas.

[0038] The air intake assembly includes a sealing plate 50 rotatably disposed inside the air intake head 33.

In actual use, under the action of the sealing plate 50, the air intake head 33 will only take in air and not take out air. The telescopic member 51 can be a spring or an elastic metal sheet with telescopic properties.

[0039] The transmission assembly includes a mounting rod 19, which is fixedly mounted on one side of the bottom wall of the storage box 11. A transmission gear 20 is rotatably connected to one side of the mounting rod 19. A rack 17 is fixedly connected to the side wall of the pneumatic telescopic cylinder 32 on one side of the transmission gear 20. The rack 17 meshes with the transmission gear 20. A drive wheel 18 is rotatably connected to the side wall of the mounting rod 19 on the axial side of the transmission gear 20. The shaft of the drive wheel 18 is fixedly connected to the end of the shaft of the transmission wheel 16. A transmission wheel 16 is rotatably connected to the outer wall of the storage box 11 on the axial side of the rotating column 22. The transmission wheel 16 is connected to the drive wheel 18. The drive wheel 18 and the transmission wheel 16 are connected by a transmission belt. When the rotating column 22 drives the guide vanes to rotate, it can drive the cold air in the storage box 11 to flow fully, thereby improving the cooling efficiency and effect.

[0040] The inspection-type cooling assembly includes a dry ice box 4 located below the mounting plate 3. An air pump 10 is located above the mounting plate 3. An adjusting screw 5 and a support column 61 are respectively located between the protective plates 2 on both sides of the air pump 10. Mounting arms 8 are fixedly connected to both sides of the air pump 10. One mounting arm 8 is threadedly connected to the adjusting screw 5, and the other mounting arm 8 is slidably connected to the support column 61. An air transmission pipe 7 is fixedly connected to the air inlet end of the air pump 10. The air transmission pipe 7 passes through the mounting plate 3 and communicates with the dry ice box 4.

A reset member 53 is fixedly connected to the inner wall of the movable groove 56. The reset member 53 can be a spring with telescopic properties or an elastic metal sheet, etc. A piston cylinder 54 is fixedly connected to one side of the reset member 53. The piston cylinder 54 is slidably disposed in the movable groove 56. An air transmission cylinder 55 is slidably disposed through the side wall of the piston cylinder 54. An air transmission groove 57 is opened on the air transmission cylinder 55. The air transmission cylinder 55 is fixedly disposed in the movable groove 56 and communicates with the air outlet head 9. Under normal conditions, the air outlet end of the air transmission groove 57 is located at the contact position with the piston cylinder 54. In this case, it is in a sealed state and no sublimated carbon dioxide gas will flow out.

[0042] In the implementation of this invention, the anthers are stored in the storage box 23. The adjusting motor 6 drives the adjusting screw 5 to intermittently rotate forward and backward, which in turn drives the air outlet 9 on the air pump 10 to move laterally back and forth via the mounting arm 8. The temperature inside the storage box 11 is monitored by the temperature sensor 44. When the temperature inside the storage box 11 exceeds the standard storage temperature, it indicates that cooling is required. At this time, the temperature sensor 44 transmits the information about the temperature increase to the temperature sensor, which in turn causes the thermal spring 48 to extend, driving the rotating arm 47 to rotate. The rotating arm 47 drives the conductive rod 46 to rise, and the conductive rod 46 contacts the through rod. The power supply 60 is electrically connected to the electric telescopic rod 41, which drives the valve rod 37 above the piston rod 40 to move, opening the valve port 38 on the valve rod 37. Corresponding to the flow channel 39, and with the venting groove 59 moving into the valve cylinder 36, the gas is propelled into the pneumatic telescopic cylinder 32 through the telescopic pipe 34 under the action of the air supply pump 35. The pneumatic telescopic cylinder 32 extends, thereby driving the lower air inlet head 33 to move down. At this time, the outlet head 9 will contact the lowered air inlet head 33 during the reciprocating lateral movement. The piston cylinder 54 on the outlet head 9 moves into the movable groove 56, so that the piston cylinder 54 is connected to the air transmission cylinder 55. Then, under the action of the air pump 10, the gas is transmitted into the air guide cylinder 30 through the outlet head 9 and the air inlet head 33, and finally sprayed into the storage box 11 through the air outlet 27. During this process, the outlet head 9 will drive the air inlet head 33 to move laterally, so that the air outlet 27 can move laterally and spray the cold air evenly into the storage box 11 to achieve rapid cooling of its interior.

[0043] Simultaneously, during the movement of the air outlet 27, it drives the side gear 17 to move laterally, which in turn drives the rotating column 22 on one side of the transmission wheel 16 to rotate through the transmission gear 20 and the drive wheel 18. The rotating column 22 drives the guide vane 21 to rotate, causing the cold air in the storage box 11 to flow evenly, thus achieving rapid cooling of the storage box 11. When the temperature drops to a suitable value, the temperature of the thermal spring 48 decreases and resets, and the electric telescopic rod 41 loses power, which drives the valve rod 37 to move down. At this time, the pneumatic telescopic cylinder 32 also resets, causing the air inlet head 33 to rise. The air inlet head 33 separates from the air outlet head 9, and the piston cylinder 54 in the air outlet head 9 resets, and the low-temperature gas no longer flows out. The above process is repeated. The device can flexibly adjust the temperature according to the actual temperature changes in the storage box 11. When the temperature is at a qualified temperature, no cooling operation is performed. While ensuring that the temperature in the storage box 11 is at the standard temperature value, the dry ice consumption is reduced, resulting in lower energy consumption and better economy. At the same time, it can prevent the adverse effects of excessively low storage temperature on the anthers, resulting in better performance.

[0044] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
