Description

Technical Field

[0001] This invention relates to the field of potato cultivation technology, and more particularly to a breeding device for potato cultivation. Background Technology

[0002] Aeroponics, as an advanced soilless cultivation method, has been widely used in the propagation of potato seedlings. This technology sprays water and nutrient solution directly onto the crop roots after atomization, which can provide sufficient water and nutrients for crop growth, while ensuring the oxygen supply to the roots and promoting healthy crop growth. However, in actual breeding, it has been found that due to the rapid growth and complex morphology of potato seedling roots, the rootstock is prone to coiling and intertwining, forming dense clumps. Existing aeroponic technology mostly uses fixed-position spray devices or nozzles to supply water and nutrient solution. These spray devices often cannot fully penetrate the intertwined root clusters and cannot dynamically adapt to changes in root morphology, resulting in dead zones in the spray coverage. As a result, some root areas receive too much atomized liquid, while other areas are severely lacking in water and nutrients, causing uneven supply. This unevenness not only reduces the utilization rate of water and nutrients but may also cause local root maldevelopment or rot. At the same time, other areas are hindered in growth due to drought stress, ultimately affecting the overall survival rate and breeding quality of potato seedlings.

[0003] In addition, existing equipment generally lacks the function of actively regulating root morphology, making it difficult to differentiate the root system according to different growth stages of the plant. Summary of the Invention

[0007] To further explain, it also includes ventilation components; at least two ventilation components are fixedly attached to each side panel.

[0008] To further clarify, a side plate is slidably connected to the incubator without being connected to the tubing.

[0009] To further explain, each dispersing mechanism includes a slide rod I; at least two slide rods I are fixedly connected to the retaining ring; all slide rods I are slidably connected to the top block; an elastic element I is sleeved on the outside of all slide rods I, one end of the elastic element I is fixedly connected to the retaining ring, and the other end of the elastic element I is fixedly connected to the top block; a top plate is fixedly connected to the end of all slide rods I away from the retaining ring, and the top plate is in contact with the top block.

[0010] To further explain, the top block is designed as a cone shape, larger at the top and smaller at the bottom.

[0011] To further clarify, both the top block and the top sheet are made of rubber.

[0012] Further explanation includes an adjustment system; the adjustment system is connected to the circular tube; the adjustment system includes a fixed ring, slide rod II, circular ring, sliding ring, elastic element II, circular plate, connecting sleeve, connecting rod, spring plate, hook, wedge block I and wedge block II; several magnets are set on the lifting plate, and each sliding frame is equipped with a magnet; a fixed ring is fixedly connected to each circular tube; at least two slide rods II are slidably connected to each fixed ring; one end of all slide rods II on the same fixed ring is fixedly connected to a circular ring; the circular ring is slidably connected to the corresponding circular tube; the ends of all slide rods II on the same fixed ring away from the corresponding circular ring are fixedly connected to a circular ring.

[0013] To further explain, both the upper inner edge and the lower inner edge of the ring are provided with curved chamfers.

[0014] To further explain, the hook has an arc-shaped groove in the middle.

[0015] The advantages and positive effects of this invention are: (1) The top block is moved upward and inserted into the clump of rootstock, thereby dispersing the potato rootstock. Then, all the top pieces move upward and touch the potato rootstock, further spreading the potato rootstock. The potato rootstock hangs down around the top block and all the top pieces, and the potato rootstock is located around the outer side of the cylinder, so that water and nutrient solution can be sprayed onto the surface of the potato rootstock.

[0016] (2) The cylinder is squeezed by the sliding frame, causing it to deform and expand outward. The expanded cylinder then squeezes the potato roots, causing them to disperse outward. This allows water and nutrient solution to penetrate the intertwined roots. Water is then atomized and sprayed onto the potato roots through four atomizing nozzles. Nutrient solution is delivered in the same way as water, thus replenishing the potato roots with water and nutrient solution. This disperses the roots, allowing water and nutrient solution to penetrate the intertwined roots. It also ensures that water and nutrient solution are sprayed more evenly and fully onto different areas of the roots, avoiding dead spots in the spraying. This improves the utilization rate of water and nutrient solution and enhances the overall survival rate and breeding quality of potato seedlings.

[0017] (3) By controlling the moving distance of the lifting plate, the cylinder can be deformed to different degrees, so as to achieve a differentiated dispersion effect on the roots and stems of potato plants at different growth stages. This is conducive to the more even spraying of water and nutrient solution on the surface of the roots and stems. By restoring all the cylinders to their original shape, the space of the cultivation box is more abundant, and the cylinders are avoided from obstructing the potato harvesting operation.

[0018] (4) By changing the angle of the four atomizing nozzles, the four atomizing nozzles are tilted upwards and directed towards the upper part of the potato root and stem. Water and nutrient solution are then delivered into the four atomizing nozzles, so that the water and nutrient solution are concentrated and sprayed towards the upper part of the potato root and stem. This further improves the uniformity of water and nutrient solution spraying and the uniformity of liquid distribution in the upper part of the root and stem. At the same time, by spraying water and nutrient solution upwards (i.e., towards the upper part of the potato root and stem) in advance, the water and nutrient solution can flow naturally downwards along the surface of the potato root and stem, gradually wetting the middle and lower parts of the root and stem. This process effectively enhances the penetration and coverage uniformity of water and nutrient solution throughout the root and stem, reduces the spray blind area, and is especially suitable for potato breeding scenarios with dense and intertwined root and stem growth.

[0019] (5) By readjusting the angle of the four atomizing nozzles to face the middle and lower root area of ​​the potato, water and nutrient solution are sprayed onto the surface of the middle and lower root of the potato. This allows for differentiated spraying of the root of the potato plant at different growth stages, which helps to spray water and nutrient solution more evenly onto the root surface.

Made of rubber; the cylinder 208 is in contact with the corresponding sliding frame 207; a retaining ring 209 is fixedly connected to the end of each cylinder 208 away from the sliding frame 207; the retaining ring 209 is slidably connected to the corresponding round tube 206; a top block 210 is fixedly connected to the end of each round tube 206 away from the base 204; a conveying pipe 211 is slidably connected to each base 204, and the lower end of the conveying pipe 211 is provided with a retaining ring 209 that cooperates with the base 204; the conveying pipe 211 is fixedly connected to the corresponding round tube 206; four atomizing nozzles 212 are installed circumferentially and equidistantly on each round tube 206, and the atomizing nozzles 212 are used to spray nutrient solution and water onto the roots and stems of potatoes; a dispersing mechanism is connected to each retaining ring 209 and the corresponding top block 210.

[0024] The incubator 1 includes an incubation plate 11, a connecting shaft 2, a shielding curtain 21, a collection box 3, a curved pipe 31, and side plates 4. The incubator 1 is equipped with an incubation plate 11, and the incubation plate 11 has several round holes equidistantly opened on it. The connecting shaft 2 is rotatably connected to the incubator 1. The shielding curtain 21 is wound around the connecting shaft 2. The collection box 3 is fixedly connected to the lower inner side of the incubator 1. The collection box 3 is fixedly connected to all the bases 204. The curved pipe 31 is fixedly connected to and connected to the collection box 3, and the curved pipe 31 passes through the incubator 1. Two side plates 4 are connected to the incubator 1. One of the side plates 4 is fixedly connected to all the conduits 205.

[0025] It also includes ventilation components 41; two ventilation components 41 are fixedly attached to each side plate 4, and the ventilation components 41 are made of mesh fabric.

[0026] A side plate 4 is not connected to the tube 205 but is slidably connected to the incubator 1 to facilitate manual harvesting of potatoes.

[0027] Each dispersing mechanism includes a slide rod I 213, an elastic element I 214, and a top plate 215; four slide rods I 213 are fixedly connected to the retaining ring 209 at equal intervals in a ring; all slide rods I 213 are slidably connected to the top block 210; an elastic element I 214 is sleeved on the outside of each slide rod I 213, the elastic element I 214 is a spring, one end of the elastic element I 214 is fixedly connected to the retaining ring 209, and the other end of the elastic element I 214 is fixedly connected to the top block 210; a top plate 215 is fixedly connected to the end of each slide rod I 213 away from the retaining ring 209, and the top plate 215 is in contact with the top block 210.

[0028] The top block 210 is designed as a cone shape, wider at the top and narrower at the bottom, to spread the potato roots outwards.

[0029] Both the top block 210 and the top plate 215 are made of rubber and are used to reduce damage to the potato roots.

[0030] The incubator 1 is equipped with a temperature and humidity monitor to monitor the ambient temperature and humidity inside the incubator 1 in real time.

[0031] The drive mechanism includes an electric slide rail 201, an electric slider 202, and a lifting plate 203; an electric slide rail 201 is fixedly connected to the inner side of each side plate 4; an electric slider 202 is slidably connected to each electric slide rail 201; all electric sliders 202 are fixedly connected to a lifting plate 203; the lifting plate 203 is damped and slidably connected to all the round tubes 206.

[0032] The external pumps used for water delivery and nutrient solution delivery are connected to two conduits 205 beforehand. Then, the virus-free potato seedlings are manually planted into the cultivation plate 11 on the cultivation box 1. As the seedlings grow, the roots of the potato plants will pass through the cultivation plate 11 and hang down below it. Subsequently, water and nutrient solution are sprayed onto the roots of the potato plants. The temperature and humidity inside the cultivation box 1 are monitored in real time by a temperature and humidity monitor installed inside the cultivation box 1.

[0033] During potato seedling growth, water and nutrient solution are required. To address the problems mentioned in the background technology, two electric sliders 202 are controlled to move upward along their corresponding electric slide rails 201. The two electric sliders 202 drive the lifting plate 203 upward, which in turn drives all the round tubes 206. For ease of explanation, the following description uses one round tube 206 as an example. The round tube 206 drives the top block 210 and the conveying pipe 211 to move upward synchronously, allowing the top block 210 to insert into the clustered rootstock, thus dispersing the rootstock. As the conveying pipe 211 continues to move upward, it stops moving upward when it is limited by the base 204. This, in turn, stops the round tubes 206 and the top block 210 from moving upward. As the lifting plate 203 continues to move upward, it disengages from the circular tube 206. As the lifting plate 203 continues to move upward, it touches the sliding frame 207 and compresses it, causing the sliding frame 207 to move upward. The sliding frame 207 drives the cylinder 208 to move, which in turn drives the retaining ring 209 to move, thereby driving the sliding rod I 213 and the top piece 215 to move and compress all the elastic elements I 214. This causes all the top pieces 215 to move upward and touch the potato roots, further spreading the potato roots and causing them to hang down around the top block 210 and all the top pieces 215, with the potato roots located around the outer perimeter of the cylinder 208.

[0034] Furthermore, as the retaining ring 209 continues to move upward, all the elastic elements I 214 are compressed to their limits, and the retaining ring 209 stops moving upward. Simultaneously, all the top plates 215 move to their limits and stop moving upward, causing the lifting plate 203 to continue moving upward, which in turn drives the sliding frame 207 to continue moving upward. The sliding frame 207 drives the cylinder 208 to move. Since the retaining ring 209 stops moving upward, the upper end of the cylinder 208 is limited, and the movement of the sliding frame 207 compresses the cylinder 208, causing it to deform and expand outward. Figure 8As shown, the potato roots are then compressed by the expanding cylinder 208, causing them to spread outwards. This allows water and nutrient solution to penetrate the intertwined roots. An external pump is then activated to deliver water to two conduits 205. The water flows along the conduits 205 into the base 204, and then into the delivery pipe 211 and the circular pipe 206. Finally, the water is atomized and sprayed onto the potato roots through four atomizing nozzles 212. The delivery of nutrient solution follows the same process as water delivery. This replenishes the potato roots with water and nutrients, disperses the roots, and allows water and nutrient solution to penetrate the intertwined roots. It also ensures that water and nutrient solution are sprayed more evenly and thoroughly to different areas of the roots, avoiding dead spots in the spraying. This improves the utilization rate of water and nutrient solution, while also increasing the overall survival rate and breeding quality of potato seedlings.

[0035] It should be noted that after the lifting plate 203 moves upward and separates from the round tube 206, it comes into contact with the sliding frame 207 and drives the sliding frame 207 to move upward continuously, thereby driving all connected components to move. This causes all elastic elements I 214 to compress the top block 210, thus keeping the top block 210 and the conveying pipe 211 in a high position and preventing them from sliding down, thereby keeping the potato roots and stems in a dispersed state.

[0036] Furthermore, by controlling the moving distance of the lifting plate 203, the cylinder 208 can be deformed to different degrees, thereby achieving a differentiated dispersion effect on the roots and stems of potato plants at different growth stages. This facilitates more even spraying of water and nutrient solution onto the surface of the roots and stems. When the potatoes mature and need to be harvested, all the cylinders 208 return to their original shape (i.e., the inner wall of all the cylinders 208 fits the outer wall of the corresponding tube 206), thus making the space in the cultivation box 1 more ample and preventing the cylinders 208 from obstructing the potato harvesting operation.

[0037] Through the arrangement of the connecting shaft 2 and the shielding curtain 21, when it is necessary to check the growth of the potatoes, the manual handle on the connecting shaft 2 is held and the connecting shaft 2 is rotated, thereby rolling up the shielding curtain 21 so that the shielding curtain 21 is rolled up in the upper area of ​​the cultivation box 1, so that the growth of the potatoes can be checked manually. The collection box 3 and the curved pipe 31 are used to collect and guide excess water and nutrient solution, thereby reducing the waste of water and nutrient solution. The ventilation component 41 is used to make the air flow in the cultivation box 1 smoother, so as to facilitate the growth of potatoes. After the potatoes are mature, one of the side plates 4 can be moved upward, so as to facilitate the manual harvesting of mature potatoes.

[0038] Example 2: Based on Example 1, according to Figures 9-11As shown, it also includes an adjustment system; the adjustment system is connected to the circular tube 206; the adjustment system includes a fixed ring 301, a slide rod II 302, a circular ring 303, a sliding ring 304, an elastic element II 3041, a circular plate 305, a connecting sleeve 306, a connecting rod 307, a spring plate 308, a hook 3081, a wedge block I 309, and a wedge block II 310; several magnets are provided on the lifting plate 203, and each sliding frame 207 is equipped with a magnet; a fixed ring 301 is fixedly connected to the upper part of the inner wall of each circular tube 206; two slide rods II 302 are slidably connected to each fixed ring 301; one end of all slide rods II 302 on the same fixed ring 301 is fixedly connected to a circular ring 303; the circular ring 303 is slidably connected to the corresponding circular tube 206; the ends of all slide rods II 302 on the same fixed ring 301 away from the corresponding circular ring 303 are fixedly connected to a sliding ring 304. 4; The sliding ring 304 is slidably connected to the corresponding round tube 206; at least two elastic elements II 3041 are fixedly connected between each sliding ring 304 and the corresponding fixed ring 301, and the elastic element II 3041 is a spring; a round piece 305 is fixedly connected to each sliding ring 304, and the round piece 305 is made of rubber; each round piece 305 is fixedly connected to the corresponding atomizing nozzle 212; a connecting sleeve 306 is fixedly connected to the outside of each atomizing nozzle 212; all connecting sleeves 306 are rotatably connected to the corresponding round tube 206; two connecting rods 307 are fixedly connected to each sliding frame 207; a spring piece 308 is fixedly connected to the end of each connecting rod 307 away from the sliding frame 207, and a hook 3081 is fixedly connected to each spring piece 308; a wedge block I 309 is fixedly connected to each spring piece 308; two wedge blocks II 310 are fixedly connected to the upper part of the inner wall of each round tube 206.

[0039] The inner upper edge and the inner lower edge of the ring 303 are both provided with arc-shaped chamfers to facilitate the movement of the hook 3081 to hook the ring 303.

[0040] The hook 3081 has an arc-shaped groove in the middle for cooperating with the slide bar II 302, so that the hook 3081 can more firmly hook the ring 303.

[0041] To further ensure a more even and thorough spraying of water and nutrient solution onto the rootstock surface, the sliding frame 207 moves upward, causing two connecting rods 307 to move upward as well. The connecting rods 307 simultaneously move the spring piece 308, hook 3081, and wedge block I 309 upward, causing wedge block I 309 to contact and be compressed by wedge block II 310. This movement of wedge block I 309 causes the spring piece 308 to bend and deform. As the connecting rod 307 continues to move upward, the hook 3081 contacts the lower edge of the ring 303. Since both the upper and lower inner edges of the ring 303 have rounded chamfers, the hook 3081 can move along the lower inner edge of the ring 303. When the hook 3081 moves past the upper inner edge of the ring 303, the elastic force of the spring piece 308 resets the hook 308, thus hooking the ring 303. Figure 11 As shown, the two electric sliders 202 are then controlled to move downwards along their corresponding electric slide rails 201. The two electric sliders 202 drive the lifting plate 203 to move downwards. The movement of the lifting plate 203 drives the sliding frame 207 to move downwards via magnetic force. The sliding frame 207 drives the two connecting rods 307 to move downwards, which in turn causes the hook 3081 to drive the ring 303 to move. The ring 303 drives the two sliding rods II 302 to slide downwards on the fixed ring 301. The two sliding rods II 302 drive the sliding ring 304 and the disc 305 to move synchronously, thereby driving the four fog lights to move downwards. The atomizing nozzle 212 moves, causing the disc 305 to deform. Simultaneously, the four connecting sleeves 306 rotate adaptively, thereby changing the angle of the four atomizing nozzles 212. This causes the four atomizing nozzles 212 to tilt upwards and face the upper part of the potato root, delivering water and nutrient solution into the four atomizing nozzles 212. This concentrates the water and nutrient solution onto the upper part of the potato root, thus evenly spraying the water and nutrient solution onto the upper part of the potato root and further improving the uniformity of water and nutrient solution spraying.

[0042] Furthermore, by evenly spraying water and nutrient solution onto the upper part of the potato rootstock, not only is the uniformity of liquid distribution in the upper part of the rootstock improved, but also, by pre-spraying water and nutrient solution upwards (i.e., onto the upper part of the potato rootstock), the water and nutrient solution can flow naturally downwards along the surface of the potato rootstock, gradually wetting the middle and lower parts of the rootstock. This process effectively enhances the penetration and coverage uniformity of water and nutrient solution throughout the rootstock, reduces blind spots, and is especially suitable for potato breeding scenarios where the rootstock is dense and intertwined.

[0043] It should be noted that when the sliding frame 207 moves upward, the cylinder 208 deforms, causing the lower and middle roots of the potato to disperse. At the same time, the sliding frame 207 drives the two connecting rods 307 to move upward, which in turn drives all connected components to move, causing the sliding ring 304 and the disc 305 to move upward synchronously and stretch the two elastic elements II 3041, which in turn causes the four atomizing nozzles 212 to move again, thereby adjusting the angle of the four atomizing nozzles 212 so that they face the lower and middle root area of ​​the potato, and then spraying water and nutrient solution onto the surface of the lower and middle root of the potato. It can also achieve differentiated spraying of the roots and stems of potato plants at different growth stages, which is conducive to more even spraying of water and nutrient solution onto the root and stem surface.

[0044] After the spraying operation is completed, the sliding frame 207 moves downward. The sliding frame 207 drives the two connecting rods 307 to move downward. The connecting rods 307 drive the spring piece 308, hook 3081 and wedge block I 309 to move downward synchronously. As a result, wedge block I 309 moves to contact wedge block II 310 and is squeezed by wedge block II 310. As a result, hook 3081 disengages from ring 303. Then, the elastic force generated by the two elastic elements II 3041 causes the sliding rod II 302, ring 303, sliding ring 304 and disc 305 to move and reset. As a result, the four atomizing nozzles 212 move and reset.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
