Description

Technical Field

[0001] The invention belongs to the field of vegetable soilless cultivation, and in particular relates to a vegetable soilless cultivation water circulation purification device. Background Art

[0002] Soilless cultivation refers to a cultivation method that uses water, peat, forest leaf mold, vermiculite and other media as the substrate for the plant roots to fix the plants, so that the plant roots can directly contact the nutrient solution. The composition of the nutrient solution in soilless cultivation is easy to control and can be adjusted at any time. It can be carried out in places with suitable light and temperature but no soil, as long as there is a certain amount of fresh water supply. Soilless cultivation is divided into hydroponics, mist (air) cultivation and matrix cultivation according to the different cultivation media.

[0003] At present, in the process of cultivating vegetables by hydroponics, the nutrient solution is transported to the culture tank through a pipeline for absorption by the vegetable roots in the culture tank, and then the nutrient solution absorbed by the vegetable roots and transpired is collected, filtered, disinfected, and supplemented with nutrients, and then transported to the culture tank again to form a closed-loop water circulation system. However, after the nutrient solution is transported to the culture tank, the nutrient solution absorbed by the vegetable roots is prone to precipitation inside the culture tank, and in the subsequent circulation of the nutrient solution, the concentration of the nutrient solution entering the culture tank will be uneven in the culture tank, with some areas having excess nutrients and some areas having insufficient nutrients, which will affect the absorption efficiency of the vegetable roots and cause uneven growth of vegetables. Some vegetables may grow slowly or stop growing due to insufficient nutrients. Summary of the invention

The right side of the culture rack 1 is connected, and the right side of the middle connection block 5 penetrates the slide 26 on the right side and is fixedly connected to the inner wall of the slide 26 on the right side. The right side of the connection blocks 5 at the upper and lower ends penetrates the slide 26 on the right side and is slidably connected to the slide 26 on the right side. A rotating mechanism 9 is arranged between the two mounting blocks 7 on the left side, and the upper parts of the three rectangular blocks 6 are all connected to the rotating mechanism 9. A connecting mechanism 10 used in conjunction with the rotating mechanism 9 is arranged on the left side of the rectangular block 6. A culture tank 11 is movably arranged inside the support frame 3. A cover plate 14 with a plurality of circular openings 13 is arranged on the upper part of the culture tank 11, and a plurality of culture dishes 15 distributed in a linear array are fixedly arranged on the bottom of the cover plate 14, and an adjustment mechanism 16 is arranged between the plurality of culture dishes 15.

[0038] In the process of soilless cultivation of vegetables, the vegetables are placed in the circular opening 13 of the cover 14 so that the roots of the vegetables are located inside the culture dish 15. The nutrient solution in the liquid storage tank 2 is then transported to the culture tank 11. The roots of the vegetables grow in contact with the nutrient solution. During the growth process, the moving mechanism 8 can be used to adjust the spacing between the three culture tanks 11 to make the growth space of the vegetables more suitable. The cooperation of the rotating mechanism 9 and the connecting mechanism 10 can drive the culture tank 11 to rotate, which is convenient for the subsequent removal of the vegetables cultivated in the culture tank 11 and the cleaning of the interior of the culture tank 11.

[0039] See also Fig.10 , Fig.12 and Fig.13 A stirring rod 17 is rotatably provided inside the liquid storage tank 2, and a plurality of stirring blades 18 are fixedly provided on the outer side of the stirring rod 17. A motor 19 is provided on the right side of the liquid storage tank 2, and the output shaft of the motor 19 is connected to the right end of the stirring rod 17. Two nutrient solution tanks 20 symmetrically distributed on the upper part of the liquid storage tank 2 are fixedly provided, and the bottom ends of the nutrient solution tanks 20 are connected to the liquid storage tank 2. A water inlet pipe 21 is provided on the right side of the upper part of the liquid storage tank 2, and a liquid outlet pipe 22 with a valve is provided on the right side of the liquid storage tank 2. Three liquid inlet pipes 23 with valves are provided on the left side of the liquid outlet pipe 22, and the ends of the three liquid inlet pipes 23 away from the liquid outlet pipe 22 are respectively connected to the corresponding culture tanks 11.

[0040] In order to facilitate the transportation of the nutrient solution in the liquid storage tank 2 to the culture tank 11, after the vegetables are placed in the circular opening 13 of the cover 14 and the roots of the vegetables are located inside the culture dish 15, the filtered water from the outside can be transported to the inside of the liquid storage tank 2 through the water inlet pipe 21, and then the nutrient solution inside the nutrient solution tank 20 is added to the inside of the liquid storage tank 2 according to the proportion. After that, the motor 19 can drive the stirring rod 17 to rotate, and the rotation of the stirring rod 17 can drive the stirring blade 18 to rotate. The stirring blade 18 can be used to fully mix the water and the nutrient solution. Then, the valve on the liquid outlet pipe 22 is opened so that the mixed nutrient solution can enter the liquid outlet pipe 22. At this time, the valves on the liquid inlet pipe 23 are opened respectively, so that the nutrient solution can continuously enter the inside of the culture tank 11 from the liquid inlet pipe 23.

[0041] See also Figure 6 and Figure 7 The culture dish 15 includes a culture ring 151 and a culture tube 152. The culture ring 151 is fixedly arranged at the bottom of the cover plate 14, and the upper end opening of the culture ring 151 is aligned with the bottom end of the circular opening 13. The culture tube 152 is slidably arranged on the outside of the culture ring 151. The adjustment mechanism 16 includes a positioning ring 161 arranged at the center of the upper part of the cover plate 14. The outer side of the positioning ring 161 is threaded with a second positioning bolt 162. The inner side of the positioning ring 161 is slidably arranged with a pull rod 1 63, and a scale line is set on the outer side of the pull rod 163, one end of the second positioning bolt 162 passes through the inner side of the positioning ring 161 and abuts against the outer side of the pull rod 163, the bottom end of the pull rod 163 moves through the cover plate 14 and is inserted into the interior of the culture tank 11, a connecting sleeve 164 is slidably set on the lower end of the outer side of the pull rod 163, and a supporting plate 165 is fixedly set on the bottom end of the connecting sleeve 164, and the bottom end of the culture tube 152 passes through the supporting plate 165 and is fixedly connected to the supporting plate 165.

[0042] In order to cultivate different kinds of vegetables, since the culture dish 15 includes a culture ring 151 and a culture tube 152, the roots of the vegetables will contact the inner bottom end of the culture tube 152 after the vegetables are placed in the circular opening 13. After the nutrient solution is transported to the interior of the culture tank 11, the nutrient solution gradually rises in the culture tank 11 and enters the culture tube 152 and the culture ring 151. At this time, the roots of the vegetables will contact the nutrient solution. When the second positioning bolt 162 is loosened, the limit lock on the pull rod 163 can be cancelled, and then The pull rod 163 can be pulled upward or downward. In the process of pulling the pull rod 163, the position of the supporting plate 165 in the culture tank 11 can be adjusted through the connecting sleeve 164. The movement of the supporting plate 165 will drive the culture tube 152 to slide on the culture ring 151, and the height position of the culture tube 152 in the culture tank 11 can be changed, thereby changing the contact depth between the vegetable roots and the nutrient solution, ensuring that each type of vegetable can obtain an appropriate and balanced supply of nutrients, which is convenient for cultivating different types of vegetables.

[0044] See also Figure 3 and Figure 4 The connecting mechanism 10 includes a first disc 101 rotatably arranged on the left side of the rectangular block 6, the left end of the rotating rod 4 located on the right side movably passes through the rectangular block 6 and is fixedly connected to the right side of the first disc 101, a second disc 102 is rotatably arranged on the left side of the first disc 101, a connecting rod 103 is fixedly arranged on the left side of the second disc 102, the left end of the connecting rod 103 passes through the sliding mouth 26 located on the left side and is fixedly arranged with a driven bevel gear 104, and the driven bevel gear 104 is meshed with the active bevel gear 903.

[0045] See also Figure 6 , Figure 8 and Fig. 9A cleaning mechanism 12 is provided at the inner bottom end of the culture tank 11, and the cleaning mechanism 12 includes two cross bars 121 fixedly provided at the inner bottom end of the culture tank 11 and symmetrically arranged on the left and right sides, and a counterweight ring 122 is movably provided on the cross bar 121.

[0046] In order to prevent the nutrient solution in the culture tank 11 from settling during the vegetable cultivation process, the second handle 905 can be rotated slightly back and forth regularly to drive the rectangular rod 901 to rotate slightly back and forth. The rotation of the rectangular rod 901 drives the active bevel gear 903 to rotate through the connecting ring 902. The rotation of the active bevel gear 903 drives the driven bevel gear 104 to rotate. The rotation of the driven bevel gear 104 drives the connecting rod 103 to rotate. The rotation of the connecting rod 103 drives the second disk 102 to rotate. The rotation of the second disk 102 drives the first disk 101 to rotate. The rotation of the first disk 101 drives the rotating rod 4 on the left to rotate. The rotation of the rotating rod 4 can drive the support frame 3 to rotate slightly forward and backward. The small rotation of the support frame 3 can drive the culture tank 11 to rotate slightly forward and backward. The culture tank 11 rotates During the process, the counterweight ring 122 will slide on the cross bar 121. The sliding of the counterweight ring 122 can drive the scraper 124 to move in the culture tank 11. The movement of the scraper 124 can stir the nutrient solution in the culture tank 11 to increase its fluidity and prevent nutrients from accumulating locally in certain areas of the culture tank 11, thereby improving the uniformity of the nutrient solution in the culture tank 11, making the nutrient solution more effective during circulation and purification, ensuring that the concentration of the nutrient solution in the culture tank 11 is more uniform, and thus helping to ensure that the roots of the vegetables can absorb nutrients evenly to meet their growth needs. When taking the cultivated vegetables, the three culture tanks 11 can be tilted in the same direction, which makes it more convenient to take the cultivated vegetables in the culture tank 11 and prevents the vegetables from being damaged by contact with the culture tank 11.

[0047] See also Figure 4 A positioning opening 105 is provided on one side of the first disk 101 close to the second disk 102 , and a first positioning bolt 106 is threadedly provided on the upper right end of the second disk 102 . The right end of the first positioning bolt 106 penetrates the first disk 101 and is inserted into the interior of the positioning opening 105 .

[0048] In order to facilitate the stirring of the nutrient solution in one of the culture tanks 11 separately, the corresponding first positioning bolt 106 can be turned to move it out of the corresponding positioning port 105. At this time, the limit of the corresponding first disc 101 is cancelled. Then, the corresponding support frame 3 can be manually moved to drive the corresponding culture tank 11 to rotate back and forth slightly, and then the scraper 124 can be used to move back and forth in the corresponding culture tank 11 to stir the nutrient solution, thereby improving the mixing uniformity of the internal nutrient solution, preventing the precipitation of some components of the internal nutrient solution, and promoting its circulation and purification effect to meet the normal growth of vegetables.

[0049] See also Fig.11 A recess 27 is provided on both sides of the support frame 3, and a T-shaped slider 28 is slidably arranged in the recess 27, and the bottom end of the T-shaped slider 28 contacts the bottom inner wall of the recess 27, one side of the T-shaped slider 28 passes through the recess 27 and is connected to the outer side of the culture tank 11, and a third positioning bolt 29 is threadedly arranged on the side of the T-shaped slider 28 away from the culture tank 11, and one side of the third positioning bolt 29 abuts against the outer side of the support frame 3.

[0050] In order to allow the vegetables in multiple culture troughs 11 to receive light more reasonably during the cultivation process, the third positioning bolt 29 can be loosened so that it does not contact the outer side of the support frame 3. At this time, the limit lock on the culture trough 11 is cancelled, and then the culture trough 11 can be pulled forward or backward, so that the three culture troughs 11 are distributed in a stepped manner, so that the vegetables cultivated in each culture trough 11 can receive light reasonably.

[0051] See also Figure 6 and Fig.11 A plurality of springs 30 are fixedly provided at the inner bottom end of the recess 27, a horizontal plate 31 is commonly provided at the top ends of the plurality of springs 30, and the upper part of the horizontal plate 31 contacts the bottom of the T-shaped slider 28, a plurality of linearly distributed arc plates 32 are fixedly provided at the inner bottom end of the support frame 3, and a plurality of arc blocks 33 used in conjunction with the arc plates 32 are provided on the left and right sides of the bottom of the culture tank 11.

[0052] In order to further prevent the nutrient solution in the culture tank 11 from precipitating, when the culture tank 11 is pulled to move inside the support frame 3, the arc block 33 at the bottom of the culture tank 11 will contact the arc plate 32, so that the culture tank 11 will vibrate up and down during the movement. The up and down vibration of the culture tank 11 can cause the nutrient solution inside it to vibrate, which can increase the fluidity of the nutrient solution in the culture tank 11, and further prevent the nutrient solution in the culture tank 11 from precipitating, which further promotes the circulation and purification effect of the nutrient solution. During the movement of the culture tank 11, the T-shaped slider 28 will move up and down, and the up and down movement of the T-shaped slider 28 will squeeze the cross plate 31. At this time, the spring 30 can make the up and down movement of the T-shaped slider 28 more uniform and stable, which helps to evenly vibrate the nutrient solution in the culture tank 11 and further improve the fluidity of the nutrient solution.

[0053] See also Figure 1 and Figure 2 The moving mechanism 8 includes a bidirectional screw 801 rotatably arranged between the two mounting blocks 7 on the right side, and two threaded sleeves 802 with opposite thread directions are threadedly arranged on the bidirectional screw 801. A first handle 803 is rotatably arranged at the bottom of the mounting block 7 at the lower end of the right side, and the top end of the first handle 803 is connected to the bottom end of the bidirectional screw 801, and the left side of the threaded sleeve 802 is connected to the right side of the corresponding connecting block 5.

[0054] In order to ensure that the vegetables cultivated in each culture groove 11 have a suitable growth space, the bidirectional screw 801 can be driven to rotate by rotating the first handle 803. The rotation of the bidirectional screw 801 can drive the support frames 3 located at the upper and lower ends to move away from each other by utilizing the cooperation of the right side slide 26, and the movement of the support frame 3 can drive the culture groove 11 to move, so that the vertical spacing of the three culture grooves 11 during use can be adjusted, thereby ensuring that the vegetables cultivated in each culture groove 11 have a suitable growth space. At the same time, during the movement of the support frame 3, the rectangular block 6 will be driven to move synchronously. The movement of the rectangular block 6 will drive the driven bevel gear 104 to rotate through the connecting rod 103. At this time, the active bevel gear 903 will also be driven to move synchronously through the cooperation of the guide plate 904 and the connecting ring 902. The rotation of the driven bevel gear 104 and the active bevel gear 903 will not be separated, so that it will not affect the subsequent driving of the culture groove 11 to rotate normally.

[0055] See also Figure 2 and Fig.10A circulation purification mechanism 24 is arranged on the upper left side of the culture rack 1, and the circulation purification mechanism 24 includes a pumping pump 241 and a filter 242 arranged on the upper left side of the culture rack 1, a liquid extraction pipe 243 is arranged at the input end of the pumping pump 241, and a liquid return pipe 244 is arranged at the output end of the pumping pump 241, and the end of the return pipe 244 away from the pumping pump 241 is connected to the liquid storage tank 2, and the end of the liquid extraction pipe 243 away from the pumping pump 241 is connected to the filter 242, and a liquid guide pipe 245 is arranged on the rear side of the filter 242, and three drainage pipes 25 with valves are arranged on the right side of the drainage pipe 245, and the three drainage pipes 25 are respectively connected to the corresponding culture tanks 11, and the drainage pipe 25 and the liquid inlet pipe 23 are both hoses.

[0056] In order to circulate and purify the nutrient solution in the culture tank 11 so that the concentration of the nutrient solution in the culture tank 11 can be more uniform, the valve on the drain pipe 25 is opened to allow the nutrient solution in the culture tank 11 to enter the liquid guide pipe 245, and then the suction pump 241 can make the nutrient solution pass through the filter 242, the suction pipe 243 and the return pipe 244 in turn to be recovered to the interior of the liquid storage tank 2. The filter 242 can intercept and remove fragments of vegetable roots, microbial metabolites, etc., to purify the nutrient solution. After the nutrient solution is collected in the interior of the liquid storage tank 2, the nutrient solution in the nutrient solution tank 20 continues to drip into the interior of the liquid storage tank 2. If the culture rack 1 is placed indoors at this time, the air supply pipe can be connected to the air port on the upper part of the liquid storage tank 2 to supply an appropriate amount of oxygen to the interior of the liquid storage tank 2 to ensure the use effect of the nutrient solution after circulation and purification.

[0057] See also Figure 5 , Figure 7 and Figure 8 A drainage pipe 34 with a valve is provided on the right side of the front of the culture tank 11, a rubber ring 35 is provided on the outer side of the lower end of the cover plate 14, and a notch 36 for use with the rubber is provided on the upper end of the inner side of the culture tank 11, and the rubber ring 35 is located in the notch 36. When the culture tank 11 is rotated and tilted, the valve on the drainage pipe 34 is opened to facilitate the discharge of some vegetable root fragments remaining in the culture tank 11, and the rubber ring 35 cooperates with the notch 36, so that the cover plate 14 can be buckled on the upper part of the culture tank 11 more stably.

[0058] During the specific work, when soilless cultivation of vegetables is carried out, the nutrient solution to be used can be mixed in the liquid storage tank 2 first, and then the nutrient solution can be continuously transported to the inside of each culture tank 11 through the liquid inlet pipe 23. At this time, the root system of the vegetables will be in contact with the nutrient solution, and the vegetables can grow normally. During the cultivation process, the suction pump 241 is always working, and the nutrient solution in the culture tank 11 can be continuously pumped into the liquid storage tank 2 through the discharge pipe 25 for purification circulation, and during the cultivation process, the culture tank 11 can be driven to move and rotate to prevent the nutrient solution in the culture tank 11 from precipitating, thereby promoting the circulation and purification effect of the nutrient solution, ensuring that the concentration of the nutrient solution in the culture tank 11 can be more uniform, so that the vegetables can grow better, and at the same time can meet the needs of different types of vegetables for nutrients and growth environment.
