Abstract
Description
Technical Field
[0001] This application relates to the field of plant tissue culture technology, and more specifically, to a plant tissue culture seedling hardening device. Background Technology
[0002] Plant tissue culture seedlings utilize the totipotency of plant cells to induce the differentiation and development of isolated plant organs, tissues, or cells into complete plants under sterile and suitable artificial conditions. Once tissue culture seedlings reach certain growth standards, such as plant height and number of leaves, they need to undergo hardening-off to gradually adapt to the natural environment. Before hardening-off, the seedlings need to be kept in a closed bottle under strong light for five to twenty days, with a shading degree of 50% to 70%.
[0003] In existing technologies, the devices used for hardening off seedlings use a movable frame to load seedling containers and shade them with a shade net. The shade net usually needs to be manually applied, which requires staff to continuously monitor changes in light intensity. However, in actual operation, it is difficult to avoid situations where seedlings are scorched due to untimely shading, resulting in a low seedling survival rate. Utility Model Content

[0032] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.
[0033] This specific embodiment is a plant tissue culture seedling hardening device, such as... Figures 1 to 5As shown, the box body 1 has a top cover at its opening. The top cover includes a top cover frame 2 connected to the box body 1. A shade panel 3 is installed inside the top cover frame 2. One end of the shade panel 3 has an elastic hook plate 15, which is connected to the top cover frame 2. The other end of the shade panel 3 has a driving mechanism 4. The driving mechanism 4 includes a metal block 17 connected to the shade panel 3. An electromagnet 18 is provided on one side of the metal block 17, and a triggering component 19 is provided on the other side of the electromagnet 18. The electromagnet 18 and the triggering component 19 are connected by a wire. The triggering component 19 can drive the shade panel 3 to move by cooperating with the electromagnet 18 and the metal block 17. The light-transmitting area on the top cover frame 2 can be covered to achieve a shading effect. By setting a driving mechanism, including a metal block 17 connected to the shading plate 3, an electromagnet 18 cooperating with the metal block 17, and a trigger component 19 that controls the electromagnet 18 to generate or lose magnetic force, the trigger component 19 receives the temperature of sunlight and uses the change in light temperature to control the electromagnet 18 and the metal block 17 to control the position of the shading plate 3. By controlling the position of the shading plate 3, the control is achieved to control whether light enters the box 1, thereby achieving the purpose of automatic shading when the light is strong, avoiding seedling scorching caused by untimely manual shading after changes in light intensity.
[0034] like Figure 3 As shown, connecting pins 8 are fixedly connected to the four corners of the bottom of the top cover frame 2. The interior of the housing 1 is provided with sleeves that fit the connecting pins 8. The top cover frame 2 is connected to the housing 1 via the connecting pins 8. When connecting the housing 1 and the top cover frame 2, the connecting pins 8 are inserted into the corresponding sleeves, and the connecting pins 8 are pressed to achieve an interference fit with the sleeves, thus completing the fixed connection between the housing 1 and the top cover frame 2. The opening structure of the top cover frame 2 is compatible with that of the housing 1. A first connecting groove 9 is provided at one end of the top of the top cover frame 2. The top cover frame 2 is internally fixedly connected to a hook plate 10 that is compatible with the elastic hook plate 15. A second connecting groove 12 is provided at the other end of the top of the top cover frame 2. A third connecting groove 13 is provided on one side of the second connecting groove 12. A guide groove 11 is provided on the side of the top cover frame 2 adjacent to the second connecting groove 12. The guide groove 11 extends from one end of the top cover frame 2 to the other end and is connected to the first connecting groove 9. The shade plate 3 is slidably connected to the top cover frame 2 through the guide groove 11. A grid bottom plate 7 is fixedly connected inside the top cover frame 2.
[0035] like Figure 4As shown, the top of the shade panel 3 has several sets of grid grooves 14, each set of grid grooves 14 being offset from the hollow grooves on the bottom plate 7. The shade panel 3 is slidably connected to the top cover frame 2 via guide grooves 11. The elastic hook plate 15 has a transverse J-shaped structure, with one end of the elastic hook plate 15 fixedly connected to the shade panel 3. The elastic hook plate 15 has an elastic part 16 in the middle. When the shade panel 3 is installed inside the top cover frame 2, it is located above the bottom plate 7. The elastic hook plate 15 and the hook plate 10 are hooked together. When the shade panel 3 is subjected to a pulling force away from the elastic hook plate 15, the elastic part 16 deforms and elongates, thereby shading the shade panel 3. The shade plate 3 is displaced to block the hollowed-out groove on the grid bottom plate 7, thus achieving the purpose of shading. When the tension disappears, the elastic part 16 returns to its original shape and drives the shade plate 3 back to its original position. The other end of the shade plate 3 is fixedly connected to the metal block 17, which is a metal sheet. The electromagnet 18 is embedded in the second connecting groove 12 and fixedly connected to the top cover frame 2. The electromagnet 18 and the metal block 17 are opposite each other but there is a gap. When the electromagnet 18 generates magnetism, it will generate an attraction force on the metal block 17, that is, generate a tension force on the shade plate 3, which will drive the shade plate 3 to move until the metal block 17 is in contact with the electromagnet 18.
[0036] like Figure 6 and Figure 7 As shown, the triggering component 19 includes a mounting box 20 embedded in the third connecting slot 13. The mounting box 20 is a square box structure with an open top. A fixing buckle 21 is fixedly connected inside the mounting box 20. The mounting box 20 also contains a conductor 22 and a power supply 23. The conductor 22 and the power supply 23 are fixedly connected to the mounting box 20 by the fixing buckle 21. The conductor 22 and the power supply 23 are electrically connected by a wire. The conductor 22 and the electromagnet 18 are electrically connected by a wire. A conductive groove 26 is opened inside the conductor 22. The conductive groove 26 has a V-shaped structure with the tip facing upward. A connector 27 is fixedly connected to both ends of the conductive groove 26. The head 27 seals the end of the conductive groove 26, and the terminal 27 is connected to the wire. One end of the terminal 27 is connected to the electromagnet 18 through the wire, and the other end of the terminal 27 is connected to the power supply 23 through the wire, so that a closed loop is formed between the power supply 23, the conductive element 22, and the electromagnet 18. A heat-concentrating plate 24 is provided at the top opening of the mounting box 20. Two sets of heat-conducting sheets 25 are fixedly connected to the bottom of the heat-concentrating plate 24. The heat-conducting sheets 25 extend into the interior of the conductive groove 26. The heat-concentrating plate 24 is a metal plate with a concave structure, which has a good light-concentrating effect. The heat-conducting sheets 25 are made of metal with good thermal conductivity, which can conduct the heat on the heat-concentrating plate 24 to the interior of the conductive groove 26.
[0037] The highest point is in the middle of the conductive groove 26. Mercury is injected into the conductive groove 26 and is evenly distributed on both sides of the highest point of the conductive groove 26 with gaps between the two parts of mercury. Two sets of heat-conducting plates 25 are respectively distributed on both sides of the highest point of the conductive groove 26 and contact the mercury inside, so as to conduct the temperature on the heat-collecting plate 24 to the mercury. When the mercury is heated and expands, the mercury on both sides will meet and contact at the highest point of the conductive groove 26, thereby forming a conductive path inside the conductive groove 26. When the heat is removed, the mercury contracts and the circuit inside the conductive groove 26 is broken. Thus, the on and off circuit of the electromagnet 18 can be automatically controlled by temperature, that is, the position of the shade plate 3 is controlled by temperature, so as to achieve the purpose of shading by automatically controlling the movement of the shade plate 3 according to the temperature.
[0038] During operation, the top cover frame 2 is first installed on top of the box 1 containing the seedling bottles. Then, the box 1 is placed in the sun to dry. The heat-collecting plate 24 receives the heat from the light and transfers it to the inside of the conductive groove 26 through the heat-conducting plate 25. It exchanges heat with the mercury inside the conductive groove 26. After the mercury expands due to heat, it forms a conductive path inside the conductive groove 26. After the circuit is connected, the electromagnet 18 generates a magnetic force and attracts the metal block 17. The attraction pulls the shade plate 3 to overcome the elastic part 16. The resistance moves towards the electromagnet 18 until the metal block 17 is in close contact with the electromagnet 18. The shade plate 3 moves to cover the hollow groove on the grid bottom plate 7, blocking the strong light from shining into the box 1. When the light temperature decreases, the mercury retracts, the inside of the conduction groove 26 is open, the electromagnet 18 is demagnetized due to lack of current, and after the attraction of the electromagnet 18 to the metal block 17 disappears, the shade plate 3 is reset under the pulling force of the elastic part 16, the hollow groove on the grid bottom plate 7 opens, and the light shines into the box 1 again.
