Description

Technical Field

[0001] The invention relates to the technical field of seedling cultivation, in particular to a poplar seedling cultivation device. Background Art

[0002] Poplars are plants of the genus Populus, which are divided into species such as Populus alba, Populus nigra, Populus euphratica, etc. They are mainly distributed in vast areas such as Central China, North China, Northwest China, and Northeast China. Poplars are light-loving species. Adequate light is conducive to their photosynthesis and growth. In an environment with insufficient light, the growth rate of poplars will slow down, the trunks may become slender, and the crowns will not be full. The cold resistance of poplars varies from species to species. Some species, such as Populus tomentosa, can adapt to the cold climate in the north and can withstand low temperatures of -20℃ to -30℃; while some southern species may suffer from frost damage in low temperature environments. Poplars also have a certain tolerance to high temperatures. In high temperature environments in summer, as long as there is enough water supply, they can generally grow normally. Before planting poplar seedlings, it is necessary to cultivate the poplar seedlings first.

Therefore, when the nutrient solution is replaced, as the nutrient solution continues to pass 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 will be difficult to fall off naturally, which will cause the inner diameter of the drain pipe 451 to become smaller, thereby affecting the normal flow of the nutrient solution and may eventually cause blockage. By setting the scraper assembly 456, when the nutrient solution continues to pass through the drain pipe 451, the continuous impact force of the nutrient solution causes the scraper assembly 456 to move in the drain pipe 451, so that the scraper assembly 456 cleans the inner wall of the drain pipe 451.

[0023] 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 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.

[0025] The driving mechanism 23 includes a connecting plate 231, and the two connecting plates 231 are symmetrically arranged on both sides of the incubator 11. The sides of the connecting plate 231 are fixedly connected to the incubator 11, and the two 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, and the top of the connecting plate 231 is rotatably connected to a side of the motor 233.

[0026] The adjusting mechanism 22 includes two connecting blocks 221, which are fixedly connected to the inner side of the adjusting frame 21. The connecting block 221 is rotatably connected to a rotating rod 222 on one side away from the adjusting frame 21. One end of the rotating rod 222 is connected to a guide assembly 223. The middle parts of the two rotating rods 222 are rotatably connected by a rotating bolt. 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 the incubator. When the adjusting frame 21 moves, the connecting block 221 is driven 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 tops of the two rotating rods 222 drive 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 and the tilted seedlings are restored to upright growth.

[0027] 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.

[0028] Specific workflow: 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.

[0029] Specifically, after placing the processed poplar branches into the cultivation box 11, place materials such as sponge and foam into the cultivation box 13, and fix the poplar branches in the cultivation box 13 so that the lower end of the poplar branches is immersed in the nutrient solution of 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 water.

[0030] After fixing the poplar branches, turn on the air pump, plant growth lamp and other equipment. 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 lighting time and intensity. At the same time, pay close attention to the temperature and pH value in the incubator 11 and adjust them as needed.

[0031] When adding nutrient solution to the cultivation box 11, the water pump 34 is turned on and the water pump 34 works in the water storage tank 31, so that the nutrient solution in the water storage tank 31 is continuously delivered to the cultivation box 11 through the connecting pipe 35. At the same time, a first one-way valve 36 is provided on the inner side of the connecting pipe 35 to prevent the nutrient solution in the cultivation box 11 from flowing back through the connecting pipe 35 when the water pump 34 stops working.

[0032] When the nutrient solution in the cultivation box 11 needs to be replaced, the extraction pump 42 is turned on. The extraction pump 42 draws the nutrient solution in the cultivation box 11 into the drainage tank 41 for storage through the extraction pipe 43. The nutrient solution in the cultivation box 11 is driven by the extraction pump 42 and continuously enters the drainage tank 41 for storage through the drainage mechanism 45.

[0033] As the roots of the poplar seedlings grow and metabolize, some root epidermal cells will continue to fall off, and 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 the nutrient solution is replaced, when the nutrient solution continues to pass 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 will be difficult to fall off naturally, which will cause the inner diameter of the drain pipe 451 to become smaller, thereby affecting the normal flow of the nutrient solution and may eventually cause blockage. By setting the scraper assembly 456, when the nutrient solution continues to pass through the drain pipe 451, the continuous impact force of the nutrient solution causes the scraper assembly 456 to move in the drain pipe 451, so that the scraper assembly 456 cleans the inner wall of the drain pipe 451.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.
