Description

Technical Field

[0001] The present invention relates to the technical field of sapling cultivation, and specifically to a poplar sapling cultivation device. Background Art

[0002] Poplars are plants of the genus Populus, which are divided into species such as Qingyang, Baiyang, Heiyang, and Huoyang, and are mainly distributed in vast areas such as Central China, North China, Northwest China, and Northeast China. Poplars are light-loving tree species. Sufficient light is conducive to their photosynthesis and promotes growth. In an environment with insufficient light, the growth rate of poplars will slow down, the tree trunks may become slender, and the tree crowns will not be plump. The cold tolerance of poplars varies by variety. Some varieties such as Populus tomentosa can adapt to the cold climate in the north and can tolerate low temperatures of -20°C to -30°C; while some southern varieties may suffer from frost damage in low-temperature environments. Poplars also have a certain tolerance to high temperatures. In the high-temperature environment in summer, as long as there is sufficient water supply, they can generally grow normally. Before planting poplar saplings, it is necessary to first cultivate poplar saplings.

[0003] Currently, poplar branches are generally inserted into a cultivation box to cultivate poplar saplings. However, when directly inserting poplar branches into the cultivation box to cultivate poplar saplings, the poplar saplings will grow crooked during the growth process. If multiple poplar saplings all grow crooked, they may squeeze and cross each other, making each poplar sapling unable to obtain sufficient growth space and causing damage to the growth of the poplar saplings themselves.

[0016] The present invention provides a poplar seedling cultivation device, which has the following beneficial effects:

[0017] 1. In this poplar seedling cultivation device, an adjusting component is provided. During the growth of poplar seedlings, by starting two driving mechanisms to drive two adjusting frames to move relatively, and at the same time when the adjusting frames move, they synchronously drive the adjusting mechanism to move upward, so as to guide the growth of the branches of poplar seedlings and avoid the situation of poplar seedlings growing crooked.

[0018] 2. In this poplar seedling cultivation device, an adjusting mechanism is provided. By starting the motor, the output end of the motor drives the lead screw to rotate in the inner cavity in the middle of the top of the connecting plate, thereby driving the moving block to move, so that the moving block drives the adjusting frame to move towards the middle of the cultivation box. When the adjusting frame moves, it drives the connecting block to move synchronously, so that the connecting block pushes the rotating rod, causing the two rotating rods to rotate, and then the tops of the two rotating rods drive the guiding component to move upward.

Thus, during the growth of poplar seedlings, the poplar seedlings are guided to make the inclined poplar seedlings resume upright growth.

[0019] 3. In this poplar seedling cultivation device, a guiding component is provided. By arranging guiding rings on both sides of the guiding plate and also evenly arranging guiding rings on the inner side of the support frame, when the moving block drives the adjusting frame to move towards the middle of the cultivation box, the adjusting frame drives the support frame to abut against the side of the guiding plate, so that the guiding rings on the guiding plate abut against the guiding rings on the support frame, thereby guiding the growth of the branches of poplar seedlings during cultivation. At the same time, by arranging arc-shaped blocks on the inner side of the guiding rings, when the support frame abuts against the guiding plate, the arc-shaped blocks can deflect the branches and leaves of the poplar seedlings on the moving path, thus avoiding the phenomenon of squeezing the branches and leaves of the inclined poplar seedlings when the support frame abuts against the guiding plate.

[0020] 4. The poplar seedling cultivation device is provided with a drainage mechanism. When it is necessary to replace the nutrient solution in the cultivation box, by turning on the extraction pump, the extraction pump pumps the nutrient solution in the cultivation box into the drainage box for storage through the extraction pipe. By setting the scraper assembly, the inner wall of the drainage pipe can be cleaned by the scraper assembly, avoiding impurities adhering to the drainage pipe. Description of the Drawings

Detailed implementation manners

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Please refer to Figures 1 - 3 , a poplar seedling cultivation device provided by an embodiment of the present invention includes:

[0034] A cultivation component 1 for cultivating poplar seedlings. A regulating component 2 is slidably connected to the top of the cultivation component 1. A water storage component 3 is fixedly connected to one side of the cultivation component 1. A drainage component 4 is fixedly connected to the side of the cultivation component 1 away from the water storage component 3;

[0035] The cultivation component 1 includes a cultivation box 11. A fixed plate 12 is fixedly connected to the inner side of the cultivation box 11. Cultivation boxes 13 are evenly placed on the top of the fixed plate 12; during use, the processed poplar branches are placed in the cultivation box 11. After placing materials such as sponges and foams in the cultivation boxes 13, the poplar branches are fixed in the cultivation boxes 13 so that the lower ends of the poplar branches are immersed in the nutrient solution in the cultivation box 11, and the immersion depth is about 1 / 3 - 1 / 2 of the length of the poplar branches, ensuring that the poplar branches are firmly fixed and will not shake in the nutrient solution;

[0036] After fixing the poplar branches, turn on the air pump, plant growth lights and other equipment. The air pump should maintain continuous ventilation to ensure sufficient dissolved oxygen in the nutrient solution. The plant growth lights provide light according to the set light time and intensity. At the same time, closely monitor the temperature and pH value in the cultivation box 11 and adjust as needed.

[0037] Please refer to Figure 4 , the water storage component 3 includes a water storage tank 31. An inlet 32 is opened at the top of the water storage tank 31. A net plate 33 is fixedly connected to the inner side of the water storage tank 31. A water pump 34 is fixedly connected to the bottom of the inner cavity of the water storage tank 31. A connecting pipe 35 is fixedly connected to the side of the water storage tank 31. The water outlet end of the water pump 34 is fixedly connected to one end of the connecting pipe 35. The other end of the connecting pipe 35 is fixedly connected to the cultivation box 11. A first one-way valve 36 is fixedly connected to the inner side of the connecting pipe 35. When adding nutrient solution to the cultivation box 11, turn on the water pump 34. The water pump 34 works in the water storage tank 31 and continuously sends the nutrient solution in the water storage tank 31 into the cultivation box 11 through the connecting pipe 35. At the same time, by setting the first one-way valve 36 on the inner side of the connecting pipe 35, it is avoided that when the water pump 34 stops working, the nutrient solution in the cultivation box 11 flows back through the connecting pipe 35.

[0038] Please refer to Figures 4 - 7 , the drainage component 4 includes a drainage tank 41. A pumping pump 42 is fixedly connected to the bottom of the inner cavity of the drainage tank 41. A pumping pipe 43 is fixedly connected to the side of the drainage tank 41. The pumping end of the pumping pump 42 is fixedly connected to one end of the pumping pipe 43. The other end of the pumping pipe 43 is fixedly connected to the cultivation box 11. A second one-way valve 44 is fixedly connected to the inner side of the pumping pipe 43. The water outlet end of the pumping pump 42 is fixedly connected to a drainage mechanism 45. When it is necessary to replace the nutrient solution in the cultivation box 11, turn on the pumping pump 42. The pumping pump 42 pumps the nutrient solution in the cultivation box 11 into the drainage tank 41 for storage through the pumping pipe 43. Driven by the pumping pump 42, the nutrient solution in the cultivation box 11 continuously enters the drainage tank 41 through the drainage mechanism 45 for storage.

[0039] The drainage mechanism 45 includes a drain pipe 451. One end of the drain pipe 451 is fixedly connected to the water outlet end of the extraction pump 42. A bracket 452 is fixedly connected to the inner side of the drain pipe 451. A fixing rod 453 is fixedly connected to the middle of the bracket 452. Sliding grooves 454 are evenly formed in the inner side of the drain pipe 451. A connecting spring 455 is fixedly connected to one side of the bracket 452 close to the fixing rod 453. One end of the connecting spring 455 away from the bracket 452 is connected to a scraper assembly 456. As the roots of poplar seedlings grow and metabolize, some root epidermal cells will continuously fall off. These fallen cells will enter the nutrient solution. At the same time, various nutrient elements in the nutrient solution may precipitate or crystallize under certain conditions. Therefore, when replacing the nutrient solution, when the nutrient solution continuously passes through the drain pipe 451, a large amount of impurities in the nutrient solution will remain on the inner wall of the drain pipe 451 and are difficult to fall off naturally. As a result, the inner diameter of the drain pipe 451 will become smaller, which will affect the normal flow of the nutrient solution and may eventually lead to a blockage phenomenon. By setting the scraper assembly 456, when the nutrient solution continuously passes through the drain pipe 451, due to the continuous impact force of the nutrient solution, the scraper assembly 456 moves in the drain pipe 451, so that the scraper assembly 456 cleans the inner wall of the drain pipe 451.

[0040] The scraper assembly 456 includes a sliding frame 4561, the middle part of the sliding frame 4561 is fixedly connected to the end of the connecting spring 455 away from the bracket 452, the end of the sliding frame 4561 is fixedly connected to a sliding block 4562, the sliding block 4562 is slidably connected to the sliding groove 454, the end of the sliding frame 4561 away from the connecting spring 455 is fixedly connected to a connecting shaft 4563, the end of the connecting shaft 4563 away from the sliding frame 4561 is fixedly connected to a fixed frame 4564, and the end of the fixed frame 4564 The connecting sleeve 4566 is fixedly connected, and the two sides of the connecting sleeve 4566 are fixedly connected with scrapers 4567. The side of the scraper 4567 away from the connecting sleeve 4566 contacts the inner wall of the drain pipe 451. The sliding frame 4561 and the fixed frame 4564 are both slidably connected with the fixed rod 453. When a large amount of nutrient solution passes through the drain pipe 451, the continuous impact force of the nutrient solution causes the sliding frame 4561 to drive the sliding block 4562 to move in the sliding groove 454, and at the same time, the sliding frame 4561 pulls the connecting spring 455 The sliding frame 4561 slides on the fixed rod 453, so that the sliding frame 4561 drives the connecting sleeve 4566 to move through the connecting shaft 4563 and the fixed frame 4564, so that the connecting sleeve 4566 drives the scraper 4567 to clean the inner wall of the drain pipe 451; the sliding block 4562 is driven by the sliding frame 4561 to slide continuously in the sliding groove 454, so that when the sliding block 4562 abuts against the inner wall of the sliding groove 454, the moving stroke of the sliding block 4562 is limited; after moving a certain distance, the connecting sleeve 4566 drives the scraper 4567 to clean the inner wall of the drain pipe 451; The connecting sleeve 4566 drives the scraper 4567 to separate from the inner cavity of the drain pipe 451, so that the scraper 4567 can clean the impurities that fall from the inner wall of the drain pipe 451 and send them out of the drain pipe 451, thereby avoiding the phenomenon that the impurities still remain in the drain pipe 451; when the work of draining the nutrient solution is completed, the sliding frame 4561 is connected to the spring 455 through the reset stretching action, so that the sliding frame 4561 moves on the fixed rod 453, so that the sliding frame 4561 drives the scraper 4567 to reset and move in the drain pipe 451.

[0041] See also Figures 8 - 10 The adjusting component 2 includes two adjusting frames 21, the bottoms of the two adjusting frames 21 are respectively slidably connected to the top two sides of the incubator 11, the sides of the adjusting frames 21 are fixedly connected with a driving mechanism 23, the side of the driving mechanism 23 away from the adjusting frame 21 is fixedly connected to the side of the incubator 11, the inner side of the adjusting frame 21 is fixedly connected with a supporting frame 24, and an adjusting mechanism 22 is arranged between the two adjusting frames 21; during the growth process of the poplar seedlings, the two driving mechanisms 23 are turned on to drive the two adjusting frames 21 to move relative to each other, and at the same time, when the adjusting frames 21 move, the adjusting mechanism 22 is driven to move upward, thereby guiding the growth of the branches of the poplar seedlings to prevent the poplar seedlings from growing crooked.

[0042] The driving mechanism 23 includes a connecting plate 231. Two connecting plates 231 are symmetrically arranged on both sides of the cultivation box 11. The side surface of the connecting plate 231 is fixedly connected to the cultivation box 11. Both sides of the top of the connecting plate 231 are fixedly connected with sliding rods 232. The middle of the top of the connecting plate 231 is fixedly connected with a motor 233. One side of the top of the connecting plate 231 away from the motor 233 is rotatably connected with a lead screw 234. The output end of the motor 233 is fixedly connected to one end of the lead screw 234. The top of the connecting plate 231 is slidably connected with a moving block 235. The number of moving blocks 235 is three. Two moving blocks 235 are slidably connected with the sliding rods 232. The third moving block 235 is threadedly connected with the lead screw 234. The side of the moving block 235 away from the connecting plate 231 is fixedly connected to the side surface of the adjusting frame 21.

[0043] The adjusting mechanism 22 includes two connecting blocks 221. The connecting blocks 221 are fixedly connected to the inner side of the adjusting frame 21. One side of the connecting block 221 away from the adjusting frame 21 is rotatably connected with a rotating rod 222. One end of the rotating rod 222 is connected with a guiding component 223. The middle parts of the two rotating rods 222 are rotatably connected by a rotating bolt. When the motor 233 is started, the output end of the motor 233 drives the lead screw 234 to rotate in the inner cavity in the middle of the top of the connecting plate 231, thereby driving the moving block 235 to move, so that the moving block 235 drives the adjusting frame 21 to move towards the middle of the cultivation box 11. When the adjusting frame 21 moves, it drives the connecting block 221 to move synchronously, so that the connecting block 221 pushes the rotating rod 222, causing the two rotating rods 222 to rotate, and further causing the tops of the two rotating rods 222 to drive the guiding component 223 to move upward. At the same time, the adjusting frame 21 continuously moves towards the middle of the cultivation box 11 through the moving block 235, so that the support frame 24 abuts against the side surface of the guiding component 223, thereby guiding the poplar saplings during the growth process of the poplar saplings and enabling the tilted saplings to resume upright growth.

[0044] The guide assembly 223 includes a guide plate 2231, the side of the guide plate 2231 is rotatably connected to one end of the rotating rod 222, and a plurality of evenly distributed guide rings 2232 are fixedly connected to both sides of the guide plate 2231, and arc blocks 2233 are fixedly connected to both sides of the inner wall of the guide ring 2232; by arranging guide rings 2232 on both sides of the guide plate 2231, and evenly arranging guide rings 2232 on the inner side of the support frame 24, when the moving block 235 drives the adjustment frame 21 to move toward the middle of the incubator 11, the adjustment frame 21 drives the support frame 24 abuts against the guide plate 2231, so that the guide ring 2232 on the guide plate 2231 abuts against the guide ring 2232 on the support frame 24, thereby guiding the growth of the branches and trunks of the poplar seedlings during cultivation and growth; at the same time, by arranging an arc block 2233 on the inner side of the guide ring 2232, when the support frame 24 abuts against the guide plate 2231, the arc block 2233 can be used to move the branches and leaves of the poplar seedlings on the moving path, thereby avoiding the phenomenon that the tilted branches and leaves of the poplar seedlings are squeezed when the support frame 24 abuts against the guide plate 2231.

[0045] Specific workflow:

[0046] Select healthy, disease-free, one-year-old poplar branches as seedling materials. The length of the poplar branches is generally about 10-15 cm, the diameter is about 0.8-1.2 cm, and there are at least 2-3 full buds on the poplar branches. Cut the lower end of the selected poplar branches into an oblique mouth with an angle of about 45°. This can increase the contact area with the nutrient solution and is conducive to the growth of the root system. Then rinse the poplar branches with clean water to remove dust and impurities on the surface. Then, soak the poplar branches in a diluted rooting agent solution. The rooting agent can promote the germination of the root system. Put the treated poplar branches into the incubation box 11, open the water storage component 3 and add the nutrient solution to the incubation component 1. During use, the nutrients will be absorbed by the poplar branches and may deteriorate due to root secretions and other reasons. When the nutrient solution needs to be irrigated When the replacement work is performed, the nutrient solution in the cultivation component 1 is extracted into the drainage component 4 by opening the drainage component 4, and the nutrient solution is replaced; at the same time, in the process of raising the poplar seedlings, the growth orientation of the growing poplar seedlings is adjusted by the adjustment component 2, so as to avoid the poplar seedlings from tilting during the cultivation process; when the poplar seedlings grow to a certain height in the hydroponic environment and the root system is relatively developed, they need to be hardened to prepare for transplanting to the soil environment. After the hardening is completed, choose a suitable time for transplanting, take the poplar seedlings out of the cultivation box 11, rinse the roots with clean water, and remove the residual nutrient solution; then transplant the seedlings to the pre-prepared soil, the soil should be loose, fertile, and well-drained; after transplanting, water enough rooting water, and provide appropriate shading and maintenance to help the seedlings adapt to the new environment.

[0047] Specifically, after placing the processed poplar branches into the cultivation box 11, place materials such as sponges and foams in the cultivation box 13, fix the poplar branches in the cultivation box 13, and immerse the lower ends of the poplar branches into the nutrient solution in the cultivation box 11. The immersion depth is about 1 / 3 - 1 / 2 of the length of the poplar branches, ensuring that the poplar branches are firmly fixed and will not shake in the water.

[0048] After fixing the poplar branches, turn on equipment such as the air pump and plant growth lamp. The air pump should maintain continuous ventilation to ensure sufficient dissolved oxygen in the nutrient solution; the plant growth lamp provides light according to the set light time and intensity. At the same time, closely monitor the temperature and pH value in the cultivation box 11 and adjust as needed.

[0049] When adding nutrient solution to the cultivation box 11, turn on the water pump 34. The water pump 34 works in the water storage tank 31, so as to continuously send the nutrient solution in the water storage tank 31 into the cultivation box 11 through the connecting pipe 35. At the same time, by setting a first one-way valve 36 inside the connecting pipe 35, it is possible to avoid the phenomenon that the nutrient solution in the cultivation box 11 flows back through the connecting pipe 35 when the water pump 34 stops working.

[0050] When it is necessary to replace the nutrient solution in the cultivation box 11, turn on the extraction pump 42. The extraction pump 42 pumps the nutrient solution in the cultivation box 11 into the drainage tank 41 for storage through the extraction pipe 43. Driven by the extraction pump 42, the nutrient solution in the cultivation box 11 continuously enters the drainage tank 41 through the drainage mechanism 45 for storage.

[0051] As the roots of the poplar saplings grow and metabolize, some root epidermal cells will continuously fall off. These fallen cells will enter the nutrient solution. At the same time, various nutrient elements in the nutrient solution may precipitate or crystallize under certain conditions. Therefore, when replacing the nutrient solution, when the nutrient solution continuously passes through the drain pipe 451, a large amount of impurities in the nutrient solution will remain on the inner wall of the drain pipe 451 and are difficult to fall off naturally, which will cause the inner diameter of the drain pipe 451 to become smaller, thus affecting the normal flow of the nutrient solution and ultimately possibly resulting in a blockage phenomenon. By setting the scraper assembly 456, when the nutrient solution continuously passes through the drain pipe 451, due to the continuous impact force of the nutrient solution, the scraper assembly 456 moves in the drain pipe 451, so that the scraper assembly 456 cleans the inner wall of the drain pipe 451.

[0052] Specifically, when a large amount of nutrient solution passes through the drain pipe 451, the continuous impact force of the nutrient solution causes the sliding frame 4561 to drive the sliding block 4562 to move in the sliding groove 454, and at the same time, the sliding frame 4561 pulls the connecting spring 455 to slide on the fixed rod 453, so that the sliding frame 4561 drives the connecting sleeve 4566 to move through the connecting shaft 4563 and the fixed frame 4564, so that the connecting sleeve 4566 drives the scraper 4567 to clean the inner wall of the drain pipe 451; the sliding block 4562 is driven to slide continuously in the sliding groove 454 by the sliding frame 4561, so that when the sliding block 4562 slides in the sliding groove 454, When the inner walls of the movable groove 454 abut against each other, the moving stroke of the sliding block 4562 is limited; after moving a certain distance, the connecting sleeve 4566 drives the scraper 4567 to separate from the inner cavity of the drain pipe 451, so that the scraper 4567 cleans the impurities that fall from the inner wall of the drain pipe 451 and sends them out of the drain pipe 451, thereby avoiding the phenomenon that the impurities still remain in the drain pipe 451; when the work of draining the nutrient solution is completed, the sliding frame 4561 is connected to the spring 455 through the reset stretching action, so that the sliding frame 4561 moves on the fixed rod 453, so that the sliding frame 4561 drives the scraper 4567 to reset and move in the drain pipe 451.

[0053] During the growth of the poplar seedlings, the two driving mechanisms 23 are turned on to drive the two adjusting frames 21 to move relative to each other. At the same time, when the adjusting frames 21 move, they drive the adjusting mechanisms 22 to move upward, thereby guiding the growth of the branches of the poplar seedlings and preventing the poplar seedlings from growing crooked.

[0054] Specifically, the motor 233 is turned on, and the output end of the motor 233 drives the screw rod 234 to rotate in the inner cavity in the middle of the top of the connecting plate 231, thereby driving the moving block 235 to move, so that the moving block 235 drives the adjusting frame 21 to move toward the middle of the incubator 11. When the adjusting frame 21 moves, it drives the connecting block 221 to move synchronously, so that the connecting block 221 pushes the rotating rod 222, so that the two rotating rods 222 rotate, and then the top of the two rotating rods 222 drives the guide assembly 223 to move upward; at the same time, the adjusting frame 21 continues to move toward the middle of the incubator 11 through the moving block 235, so that the supporting frame 24 is against the side of the guide assembly 223, so that during the growth process of the poplar seedlings, the poplar seedlings are guided, so that the tilted poplar seedlings can resume upright growth.

[0055] More specifically, by arranging guide rings 2232 on both sides of the guide plate 2231 and evenly arranging guide rings 2232 on the inner side of the support frame 24, when the moving block 235 drives the adjusting frame 21 to move toward the middle of the incubator 11, the adjusting frame 21 drives the support frame 24 to abut against the guide plate 2231, and then the guide ring 2232 on the guide plate 2231 abuts against the guide ring 2232 on the support frame 24, thereby guiding the growth of the branches and trunks of the poplar seedlings during cultivation and growth; at the same time, by arranging an arc block 2233 on the inner side of the guide ring 2232, when the support frame 24 abuts against the guide plate 2231, the branches and leaves of the poplar seedlings on the moving path can be moved by the arc block 2233, thereby avoiding the phenomenon that the tilted branches and leaves of the poplar seedlings are squeezed when the support frame 24 abuts against the guide plate 2231.
