A limit block 16 for limiting is installed inside each slide rail 11.

[0048] The support rods 2 include four, two in a group, and are respectively fixedly connected to the bottom of the corresponding slide rails 11 by bolts, and the bottom ends of the support rods 2 are arranged on the waste liquid collection mechanism 4. A guide groove is provided on the side wall of each slide rail 11, and the setting of the guide groove is used to further ensure the stability of the displacement of the cross beam 12.

[0049] The crossbeam 12 includes a beam frame 121 located between two slide rails 11, and pulleys 122 are installed at both ends of the beam frame 121 through a rotating shaft.

The movement of the reciprocating screw 53 causes the moving plate 443 threadedly connected thereto to reciprocate, thereby driving the push rod 441 to move synchronously, so that the scraper 442 scrapes and cleans the filter screen.

[0073] The transmission gear chain member 54 is composed of a driving gear, a driven gear and a transmission chain. There are two driven gears, which are respectively arranged on corresponding driving rods. The driving gear and the driven gear are connected by a transmission chain.

[0074] The working principle of the present invention is: when the product is in use, the growth space of the cultivated plants needs to be adjusted in different growth stages, and the telescopic mechanism 1 on the planting rack is driven and adjusted through an external control system, so as to adjust the spacing of the various planting mechanisms 3 loaded thereon.

[0075] The double working cylinder group 143 of the end adjustment assembly 14 in the telescopic mechanism 1 operates, thereby causing the hollow plates 144 connected to the two ends to move synchronously, and the hollow plates 144 realize the movement of the scissor-type connecting rods 13 at both sides through the adjustment rod 15 during the displacement movement. When the active cross rod group in the scissor-type connecting rod 13 moves, the driven cross rod group and the tail cross rod group connected thereto move synchronously, thereby causing multiple beams 12 in the telescopic mechanism 1 except the frontmost cross beam 12 to move horizontally at equal intervals. In this way, the displacement adjustment of each planting mechanism 3 loaded on each cross beam 12 is achieved, so that the plants on each planting mechanism 3 have a suitable growth space.

[0076] When it is necessary to observe and perform other processing operations on the plants in each cultivation layer 35 in the multiple planting mechanisms 3, the external control system turns on the motor of the driving member 52 in the driving assembly 5. After the motor is turned on, it drives the reciprocating screw 53 to rotate, and during the rotation of the reciprocating screw 53, the moving plate 443 in the scraping member 44 threadedly connected thereto performs linear displacement with the movement of the reciprocating screw 53 under the guidance of the push rod 441. While the moving plate 443 drives the push rod 441 to move, the scrapers 442 arranged on the push rod 441 move synchronously, thereby scraping and cleaning the filter screen on the guide plate 42.

[0077] When the reciprocating screw 53 rotates, the rotating parts 51 on both sides can be moved synchronously through the setting of the transmission gear chain part 54. The driving rod in the rotating part 51 synchronously drives the worm sleeve 368 of the adjustment assembly 36 in each planting mechanism 3 to move synchronously during the rotation process. The worm sleeve 368 and the worm wheel 367 are meshed and driven, thereby driving the sleeve 3651 in the transmission part 365 to move. When the sleeve 3651 rotates, the active gear ring 366 is moved through the displacement rod 3652. The active gear ring 366 and the driven gear ring 362 are meshed and driven, and the driven gear ring 362 and the transmission gear ring 363 are also meshed and driven, thereby synchronously realizing the movement of the coupling 361 and the rotating shaft. The rotating shaft synchronously realizes the rotation of the hand plate 364 during the movement.

[0078] The coupling 361 drives the corresponding conveying shaft to move during the rotational movement, and the movement of the conveying shaft causes the conveying toothed chain member 33 to move. When the conveying toothed chain member 33 moves, the multiple splicing members 34 equidistantly arranged on its conveying chain are displaced and adjusted, thereby realizing the position switching of each cultivation layer 35, facilitating the adjustment of the cultivation layer 35 between the upper and lower positions on the planting mechanism 3, and facilitating the staff to observe and perform other processing operations on the plants on each cultivation layer 35.

[0079] If it is necessary to perform sampling operation on a single planting mechanism 3 among the planting mechanisms 3, after closing the driving assembly 5, the limit screw rods 3653 of the transmission member 365 in the adjusting assembly 36 at the positions on both sides of the selected planting mechanism 3 are adjusted. The limit locking between the current limit screw rod 3653 and the corresponding sleeve 3651 is canceled, and then the corresponding displacement rod 3652 is pulled out, so that the active gear ring 366 on the displacement rod 3652 is disengaged from the corresponding driven gear ring 362.

[0080] At this time, by manually adjusting the hand plate 364 in any adjustment component 36 in the planting mechanism 3, the corresponding rotating shaft can be moved. The rotating shaft synchronously realizes the movement of the transmission gear ring 363 during the movement, and the transmission gear ring 363 and the driven gear ring 362 are meshed and transmitted. Then the coupling 361 is driven to move through the connecting shaft, so as to realize the movement of the conveying gear chain member 33 in the planting mechanism 3. The movement of the conveying gear chain member 33 in the planting mechanism 3 enables the switching and adjustment of each cultivation layer 35 thereon, so as to facilitate the sampling and observation of plants in each cultivation layer 35. After the sampling operation is completed, the limiting screw rod 3653 of the transmission member 365 in the adjustment component 36 is adjusted again to adjust the position of the active gear ring 366, so that the active gear ring 366 and the driven gear ring 362 are meshed again, which is convenient for the subsequent adjustment of the electric control.

[0081] If it is necessary to replace the nutrient solution in different cultivation layers 35 in each planting mechanism 3, first drive the cultivation layers 35 in each planting mechanism 3 to switch through the driving component 5. The driving component 5 will pause for a while after running for a period of time, when the cultivation layer 35 moves to the bottom position. During the period of time when the driving component 5 is paused, the electric control valve on the discharge pipe of the cultivation layer 35 is opened, so that the waste liquid in the cultivation layer 35 is discharged into the collection box 41 of the waste liquid collection mechanism 4 below. After entering the collection box 41, the waste liquid is filtered through the guide plate 42 and the filter screen thereon, thereby realizing the pretreatment of the waste liquid.

[0082] When the waste liquid in the cultivation layer 35 is discharged, the electric control valve on the discharge pipe is closed, and the drive assembly 5 is turned on again, so that the cultivation layer 35 is switched and adjusted. The cycle is repeated. When the cultivation layer 35 that has completed the waste liquid discharge reaches the top of the conveying gear chain 33, the external pump pumps new nutrient solution into the main pipe above the telescopic mechanism 1 under the control of the control system. The electric control valve on the corresponding irrigation pipe is opened, and the nutrient solution in the main pipe enters the current cultivation layer 35 from the irrigation pipe, thereby replacing the nutrient solution in the cultivation layer 35 during hydroponics.

[0083] The waste liquid entering the waste liquid collecting mechanism 4 is temporarily stored in the collecting box 41 after filtering, and then extracted by an external liquid pump for subsequent processing steps, thereby realizing partial water circulation treatment during plant cultivation.

[0084] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
