Description

Technical Field

[0001] The invention relates to the technical field of symbiotic cultivation devices, in particular to a symbiotic cultivation device for freshwater algae and forage grass. Background Art

[0002] Algae are a type of eukaryotic organism (some are also prokaryotes) in the kingdom Protists. They are mainly aquatic and can carry out photosynthesis. Freshwater algae are usually cultivated in culture tubes; forage refers to grass or other herbaceous plants fed by livestock. When forage is cultivated artificially, it is cultivated in culture pots, and the roots at the bottom are drip-irrigated through pipes to maintain normal growth needs.

[0003] However, the organic wastewater or excess nutrient solution generated by the traditional freshwater algae culture tubes for algae cultivation is directly discharged for wastewater treatment, which is not convenient for secondary or multiple utilization and has a low resource utilization rate. When cultivating forage grass, the soil of the forage grass pot is easy to fall off during transportation and is difficult to clean. At the same time, when the cultivated forage grass is taken out of the breeding pond, the roots of the forage grass will take away the water in the pond, and the water carried by the roots will fall to the ground during transportation, which is relatively wasteful. In addition, the water droplets carrying the nutrient soil are difficult to clean, and the cleanliness of the device is low. The area of ​​the breeding pond is large, and the center of the pond is difficult to reach. It is inconvenient to send the breeding board to the center of the breeding pond, and the placement of the breeding board is more difficult. The breeding basin is easy to shake during transportation, resulting in a large amount of nutrient soil loss, and the stability of the breeding basin is poor. At the same time, when the water storage inside the breeding pond increases, the breeding basin is easy to lift up, which will also accelerate soil loss, and the use effect of the breeding basin is poor.

The rhizomes at the bottom of the forage grass are in contact with the nutrient solution inside the culture pond 1. The nutrient solution inside the culture pond 1 and the organic wastewater and excess nutrient solution generated by cultivating freshwater algae provide water and nutrition for the forage grass, thereby improving energy utilization efficiency.

[0029] Specifically, such as Figure 1 、 Figure 3 、 Figure 4 、 Figure 13 and Figure 14 As shown, the conveying structure 6 includes a conveying pool 601 and multiple groups of drive shafts 602 rotatably connected to the inside of the conveying pool 601. The conveying pool 601 is provided on the open space on one side of the breeding pond 1. Two drive shafts 602 in each group are fixedly connected to two drive disks 603.

The end of the fixed frame 306 is rotatably connected to two guide wheels 313, and the guide wheels 313 are rollingly connected to the inside of the guide groove 312;

[0032] The hanging structure 4 includes a hydraulic rod 401 and a lifting frame 402 fixedly connected to the telescopic end of the hydraulic rod 401. The hydraulic rod 401 is fixedly connected to the mounting frame 309. The lifting frame 402 is fixedly connected to a third motor 404. A third screw 405 is rotatably connected to the lifting frame 402. The thread directions of the two ends of the third screw 405 are opposite. The output end of the third motor 404 is fixedly connected to the third screw 405. Two lifting frames with L-shaped cross sections are symmetrically threaded on the third screw 405.

The first screw 303 rotates and drives the slide 304 to slide left and right on the first guide rod 305. The slide 304 drives the fixed frame 306 to move to the designated position. After the fixed frame 306 is in place, the second motor 307 on the fixed frame 306 is started, the second motor 307 drives the second screw 308 to rotate, and the second screw 308 rotates and drives the mounting frame 309 to slide back and forth on the second guide rod 310. After the mounting frame 309 slides into place, the hydraulic The rod 401 and the third motor 404 are started at the same time. When the hydraulic rod 401 is extended, the lifting frame 402 is driven to descend. When the lifting frame 402 descends, the lifting bar 406 is driven to descend. The third motor 404 drives the third screw 405 to rotate. The thread directions at both ends of the third screw 405 are opposite. The third screw 405 rotates to drive the two lifting bars 406 to slide toward each other, so that the lifting ear 408 will not block the descent of the lifting bar 406. After descending to a certain position, the third motor 404 drives the third screw 405 to rotate in the opposite direction. The third screw 405 drives the two lifting bars 406 to move back to each other, and the bottom end of the lifting bar 406 moves to The bottom end of the lifting ear 408 is then retracted by the hydraulic rod 401. The hydraulic rod 401 drives the lifting frame 402 to rise, thereby driving the limiting hole 410 on the lifting bar 406 to be plugged into the limiting column 409 at the bottom end of the lifting ear 408. The hydraulic rod 401 is continued to be retracted to drive the lifting ear 408 and the breeding plate 9 to rise. The breeding plate 9 is separated from the conveyor belt 604. The first motor 302 and the second motor 307 are then started to transfer the breeding plate 9 to the specified position. The hydraulic rod 401 is then extended to plug the breeding plate 9 into the plug block 206 on the mounting plate 205 at the specified position. The hydraulic rod 401 is then continued to be extended to make the lifting bar 406 and the breeding plate 9 separate. After the limiting posts 409 are separated, the third motor 404 is activated, causing the two lifting bars 406 to move toward each other. The hydraulic rod 401 is then retracted. This reciprocating motion transfers the culture plates 9 on the conveyor belt 604 to the interior of the culture tank 1. Simultaneously, the culture plates 9 inside the culture tank 1 can also be transferred to the conveyor belt 604, making the transfer of the culture plates 9 more convenient.

[0033] Specifically, such as Figure 2 、 Figure 5 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12As shown, the fixed structure 5 includes a placement groove 501 and a positioning column 502. The breeding plate 9 is provided with a plurality of placement grooves 501. The breeding basin 10 is placed inside the placement groove 501. The breeding plate 9 is provided with a plurality of positioning columns 502. The breeding basin 10 is provided with a positioning hole 503. The positioning columns 502 are plugged into the positioning holes 503. A fixing bar 504 is fixedly connected to the breeding plate 9. The fixing bar 504 is internally slidably connected to two slide bars 505. The slide bars 505 are fixedly connected to the There is a card block 506, a card slot 507 is provided on the breeding basin 10, the card block 506 is slidably connected to the fixed bar 504, the card block 506 is engaged with the card slot 507, the interior of the fixed bar 504 is fixedly connected with three guide shafts 509, the slide bar 505 is slidably connected to the guide shaft 509, the outer sleeve of the guide shaft 509 is provided with a spring 510, the two ends of the spring 510 are respectively fixedly connected to the two slide bars 505, the slide bar 505 is fixedly connected with a dial block 508, the dial block 5 08 is slidably connected to the fixing bar 504; when placing the breeding basin 10, align the positioning hole 503 at the bottom end of the breeding basin 10 with the positioning column 502 on the breeding plate 9, and then put the breeding basin 10 into the placement groove 501, and at the same time make the side of the breeding basin 10 with the card slot 507 face the fixing bar 504. When placing, move the dial block 508, the dial block 508 drives the slide bar 505 to slide, and the slide bar 505 drives the card block 506 to slide. The card block 506 will not block the breeding basin 10. At the same time, when the slide bar 505 slides, the spring 5 10 is compressed. When the breeding basin 10 is completely put in, the shifting block 508 is released, and the spring 510 resets to drive the slide bar 505 and the block 506 to reset. The block 506 then engages with the slot 507 on the breeding basin 10. In this way, multiple breeding basins 10 are fixed on the breeding plate 9, which improves the stability of the breeding basin 10 during movement and transportation, and prevents the breeding basin 10 from floating out due to the rising water surface inside the breeding pond 1. The setting of the guide shaft 509 improves the sliding stability of the slide bar 505 and prevents the spring 510 from deviating.

[0034] When the present invention is used, first, freshwater algae are cultured through the culture tube 8, and excess nutrient solution or organic waste liquid generated by the culture is discharged through the drain pipe 201. The discharged liquid flows from the connecting pipe 202 to the delivery pipe 203, and flows into the interior of the culture pond 1 through multiple branch pipes 204 on the delivery pipe 203. The interior of the culture pond 1 is filled with water. At the same time, multiple culture plates 9 are plugged into the installation plate 205 through the plug block 206. Multiple culture basins 10 are placed on the culture plates 9. Forage grass is cultivated in the culture basins 10. The roots at the bottom of the forage grass are in contact with the nutrient solution in the culture pond 1. The nutrient solution in the culture pond 1, the organic wastewater generated by the cultivation of freshwater algae, and the excess nutrient solution provide water and nutrition for the forage grass, thereby improving energy utilization efficiency.

[0035] Then, the conveying trolley conveys the stacked culture plates 9 to the vicinity of the conveying pool 601, and the culture plates 9 are transferred from the conveying trolley to the conveyor belt 604 by the manipulator, and the fourth motor 605 is started. The fourth motor 605 rotates to drive the drive shaft 602 to rotate, and the drive shaft 602 rotates to drive the drive disk 603 to rotate, and the drive disk 603 rotates to drive the conveyor belt 604 to move, and then the culture plates 9 are conveyed to the designated position. During the conveying, the nutrient soil inside the culture basin 10 will fall into the inside of the collection frame 701. At the same time, when the culture plates 9 are taken out of the culture pool 1, The roots of the forage grass will take away the water in the breeding pond 1, and the water and the nutrient soil in the breeding basin 10 will drip. The water will be filtered by the filter 703 and then flow back into the interior of the breeding pond 1 through the one-way pipe 705, thereby reducing the waste of water resources. The collection frame 701 is regularly pulled out from the conveying pool 601 by pulling the handle 702, and the soil collected in the collection frame 701 is cleaned, thereby improving the cleanliness of the device. At the same time, since the collection frame 701 is set at an angle, the dripping water and soil will not overflow from the pull-out port of the collection frame 701, thereby improving the use effect of the device.

[0036] Secondly, when the breeding plate 9 is transported to the designated position by the conveyor belt 604, the first motor 302 on the gantry 301 is started, which drives the first screw 303 to rotate. The rotation of the first screw 303 drives the slide 304 to slide left and right on the first guide rod 305. The slide 304 drives the fixed frame 306 to move to the designated position. After the fixed frame 306 is in place, the second motor 307 on the fixed frame 306 is started, the second motor 307 drives the second screw 308 to rotate, and the second screw 308 rotates to drive the mounting frame 309 to slide back and forth on the second guide rod 310. After the mounting frame 309 slides into place, The hydraulic rod 401 and the third motor 404 are started at the same time. When the hydraulic rod 401 is extended, it drives the lifting frame 402 to descend. When the lifting frame 402 descends, it drives the lifting bar 406 to descend. The third motor 404 drives the third screw 405 to rotate. The thread directions at both ends of the third screw 405 are opposite. The third screw 405 rotates to drive the two lifting bars 406 to slide toward each other, so that the lifting ear 408 will not block the descent of the lifting bar 406. After descending to a certain position, the third motor 404 drives the third screw 405 to rotate in the opposite direction. The third screw 405 drives the two lifting bars 406 to move back to back, and the bottom end of the lifting bar 406 moves The hydraulic rod 401 is retracted to move to the bottom of the lifting ear 408, and then the hydraulic rod 401 is retracted. The hydraulic rod 401 drives the lifting frame 402 to rise, and then drives the limiting hole 410 on the lifting bar 406 to plug with the limiting column 409 at the bottom of the lifting ear 408. The hydraulic rod 401 is further retracted to drive the lifting ear 408 and the breeding plate 9 to rise. The breeding plate 9 is separated from the conveyor belt 604, and then the first motor 302 and the second motor 307 are started to transfer the breeding plate 9 to the specified position. The hydraulic rod 401 is then extended to plug the breeding plate 9 into the plug block 206 on the mounting plate 205 at the specified position. The hydraulic rod 401 is then further extended to make the lifting bar 406 After separating from the limiting column 409, the third motor 404 is started to make the two lifting bars 406 move toward each other, and then the hydraulic rod 401 is retracted. In this way, the breeding plate 9 on the conveyor belt 604 is transferred to the inside of the breeding pond 1. At the same time, the breeding plate 9 inside the breeding pond 1 can also be transferred to the conveyor belt 604, which improves the convenience of transferring the breeding plate 9. The setting of the guide bar 403 improves the sliding stability of the lifting frame 402. The setting of the third guide rod 407 improves the sliding stability of the lifting bar 406. The setting of the support frame 311, the guide groove 312 and the guide wheel 313 improves the stability of the fixed frame 306 when moving.

[0037] Finally, when placing the breeding basin 10, align the positioning hole 503 at the bottom end of the breeding basin 10 with the positioning column 502 on the breeding plate 9, and then put the breeding basin 10 into the placement groove 501, and at the same time make the side of the breeding basin 10 with the card slot 507 face the fixed bar 504. When placing, move the dial block 508, the dial block 508 drives the slide bar 505 to slide, and the slide bar 505 drives the card block 506 to slide. The card block 506 will not block the breeding basin 10. At the same time, when the slide bar 505 slides, the spring 510 is compressed. After the breeding basin 10 is completely placed in, the shift block 508 is released, and the spring 510 resets to drive the slide bar 505 and the block 506 to reset, and the block 506 then engages with the slot 507 on the breeding basin 10. In this way, multiple breeding basins 10 are fixed on the breeding plate 9, which improves the stability of the breeding basin 10 during movement and transportation, and prevents the breeding basin 10 from floating out due to the rising water surface inside the breeding pond 1. The setting of the guide shaft 509 improves the sliding stability of the slide bar 505 and prevents the spring 510 from deviating.
