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 Protista. They are mainly aquatic and can carry out photosynthesis. The cultivation of freshwater algae is usually carried out 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 tube for algae cultivation is directly discharged for wastewater treatment, which is not convenient for secondary or multiple utilization, and the resource utilization rate is low; 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 from 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, and 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, so it is inconvenient to send the breeding board to the center of the breeding pond, and the placement of the breeding board is difficult; the breeding basin is easy to shake during transportation of the breeding board, resulting in a large loss of nutrient soil, 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.

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 threads at both ends of the third screw 405 are in opposite directions. 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 in reverse, and the bottom ends of the lifting bars 406 move The hydraulic rod 401 moves to the bottom of the lifting ear 408, and then retracts the hydraulic rod 401, which drives the lifting frame 402 to rise, thereby driving the limiting hole 410 on the lifting bar 406 to plug with the limiting column 409 at the bottom of the lifting ear 408, and continues to retract the hydraulic rod 401 to drive the lifting ear 408 and the breeding board 9 to rise, and the breeding board 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 board 9 to the specified position, and then the hydraulic rod 401 is extended to plug the breeding board 9 into the plug block 206 on the mounting plate 205 at the specified position, and then the hydraulic rod 401 is continued to be extended to make the lifting bar 406 After being separated 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, so that the breeding board 9 on the conveyor belt 604 is transferred to the inside of the breeding pool 1, and the breeding board 9 inside the breeding pool 1 can also be transferred to the conveyor belt 604, which improves the convenience of transferring the breeding board 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, and 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; 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 put 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 board 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 running off.
