[0029] In order to provide different forms of planting environments as required, please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4, it is necessary to set up a rotating array cultivation mechanism 1, which internally has multiple cultivation boxes 16 arranged in a linear array for vegetable cultivation, a first rotating frame 11 installed through bearings at one rotating end of the cultivation box 16 and capable of rotating, and a heavy object block 112 installed at the other rotating end of the cultivation box 16 and capable of keeping the cultivation box 16 in a horizontal state under gravity. By rotating the first rotating frame 11 and the second rotating frame 12, multiple cultivation boxes 16 can rotate around the axis line of the first docking plate 111 until the cultivation box 16 rotates to a suitable position. During the rotation process, due to the existence of the heavy object block 112, the cultivation box 16 will always remain in a horizontal state, so that different forms of planting environments can be provided according to requirements.

[0030] For the specific structure of the rotating array cultivation mechanism 1, please refer to Figure 3 and Figure 4 , including a second rotating frame 12 symmetrically arranged with the first rotating frame 11. The interiors of the first rotating frame 11 and the second rotating frame 12 are respectively provided with a first shaft body installation hole 13 and a second shaft body installation hole 14 with both ends open. The interior of the first rotating frame 11 is provided with a first liquid flow hole 15 connecting the space below it and each first shaft body installation hole 13. The interior of the cultivation box 16 is provided with a cultivation pool 17 for filling plants. One end of the cultivation box 16 is provided with a first rotating shaft 113 integrally formed with it and installed inside the first shaft body installation hole 13 through bearings and seals. The other end of the cultivation box 16 is provided with a second rotating shaft 114 integrally formed with it and installed inside the second shaft body installation hole 14 through bearings. One end of the second rotating shaft 114 is fixedly installed with a heavy object block 112. A ring-shaped liquid flow hole 18 is provided inside the circumferential wall thickness of the cultivation box 16. The interior of the cultivation box 16 is provided with a plurality of irrigation holes 19 connecting the ring-shaped liquid flow hole 18 and the cultivation pool 17. A second liquid flow hole 110 connecting the first liquid flow hole 15 and the ring-shaped liquid flow hole 18 is provided inside the first rotating shaft 113. One end of the center part of the first rotating frame 11 is fixedly installed with a first docking plate 111. The center of gravity of the heavy object block 112 is set on one side deviating from the axis line of the second rotating shaft 114, and the center of gravity of the heavy object block 112 is located directly below the axis line of the second rotating shaft 114. The gravity of the heavy object block 112 is sufficient to keep the cultivation box 16 in a horizontal state.

[0031] In order to lock the rotating array cultivation mechanism 1, please refer to Figure 1 , Figure 2 , Figure 5 and Figure 6, a locking driven mechanism 2 is required, wherein a gear 27 capable of rotating with the first rotating frame 11, a gear bar 212 meshing with the gear 27 and capable of producing a longitudinal movement effect with the rotation of the gear 27, a brake plate 211 providing friction force to the gear bar 212 so that the gear bar 212 remains stationary, and a coil spring 210 exerting an elastic force on the brake plate 211. When the first rotating frame 11 rotates in a directional manner, the gear 27 will rotate accordingly. Due to the meshing effect of the tooth structure, the gear bar 212 will produce a The longitudinal movement phenomenon can be achieved by controlling the rotation direction of the No. 1 rotating frame 11, so as to control the longitudinal movement direction of the gear bar 212. When it moves to a suitable angle, the torque on the No. 1 rotating frame 11 is cancelled. Due to the elastic strength of the coil spring 210, the brake plate 211 produces a friction phenomenon against the gear bar 212, and the maximum static friction force in the friction phenomenon is sufficient to keep the No. 1 rotating frame 11 stationary, and each incubator 16 is kept stationary, thereby having a locking effect on the rotating array-type incubation mechanism 1.

[0032] For the specific structure of the locking driven mechanism 2, please refer to Figure 5 and Figure 6, including a rectangular housing 21, inside which there is a rectangular component moving cavity 22 with an open top. In the middle of one side of the rectangular component moving cavity 22, there is a gear mounting cavity 24. At the bottom of the rectangular component moving cavity 22, there is a rod perforation 23. At the center of the rectangular housing 21, corresponding to the rectangular component moving cavity 22, a rotatable third rotating shaft 25 is installed through a bearing. One end of the third rotating shaft 25 is fixedly connected to the first docking plate 111 through a second docking plate 26. Inside the gear mounting cavity 24, a gear 27 is fixedly installed on the shaft of the third rotating shaft 25. Inside the rectangular component moving cavity 22 of the rectangular housing 21, there is a gear rack 212 that can move longitudinally and meshes with the gear 27 through a toothed structure. At the bottom of the gear rack 212, there is a rod fixing groove 213 with an inward concave structure. On the other side of the rectangular component moving cavity 22 of the rectangular housing 21, there is a horizontal component moving cavity 28 in a horizontal state. Inside the horizontal component moving cavity 28, there is an internal moving plate 29 that can move along its axial direction. One end of the internal moving plate 29 is provided with a braking plate 211 that penetrates the internal structure of the rectangular housing 21 and abuts against one side of the gear rack 212. At the other end of the internal moving plate 29, a compressed spiral spring 210 is fixedly installed. The maximum static friction force generated by the spiral spring 210 on the braking plate 211 and the gear rack 212 is sufficient to keep the first rotating frame 11 in a static state. The structural shape of the longitudinal projection of the gear rack 212 is the same as that of the cross-section of the rectangular component moving cavity 22, both being rectangular structures, and the structural size of the longitudinal projection of the gear rack 212 matches the structural shape of the cross-section of the rectangular component moving cavity 22.

[0033] In order to utilize the kinetic energy of the gear rack 212 to generate a water supply phenomenon, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8, it is necessary to set up a driven water supply mechanism 3, which is internally provided with a longitudinal support housing 32 that can provide a height support effect for the rectangular housing 21 and is hollow inside, a piston body 38 located inside the longitudinal support housing 32 and capable of longitudinally moving along with the rack 212, and a first liquid check valve 310 and a second liquid check valve 311 that can control the flow of water from the outside to the inside of the first liquid flow hole 15. During the longitudinal movement of the rack 212, it will drive the piston body 38 to produce a longitudinal movement effect. At this time, the space below the piston body 38 will change, so as to suck the clear water in the reservoir into the liquid compression chamber 33 and the third liquid flow hole 34, and then press the clear water in the liquid compression chamber 33 and the third liquid flow hole 34 into the liquid reserved cavity 35. Finally, the clear water will enter the first liquid flow hole 15 through the water supply hose 36, and then enter the filler through each annular liquid flow hole 18 and the irrigation hole 19 to supply water to the vegetable seeds in the filler, so as to utilize the kinetic energy of the rack 212 to generate a water supply phenomenon and improve the effective utilization rate of the kinetic energy.

[0034] For the specific structure of the driven water supply mechanism 3, please refer to Figure 7 and Figure 8 , including a horizontal support substrate 31 that provides a horizontal support effect. On one side of the upper surface of the horizontal support substrate 31, there is a longitudinal support housing 32 integrally formed with it. The top end of the longitudinal support housing 32 is fixedly installed at the bottom end of the rectangular housing 21. Inside the rectangular housing 21, there is a liquid compression chamber 33 with a top-connected rod body perforation 23. Inside the horizontal support substrate 31, there is a liquid reserved cavity 35. The liquid compression chamber 33 and the liquid reserved cavity 35 are connected through a third liquid flow hole 34. The structure of the third liquid flow hole 34 near its top is connected to the outside space through a fourth liquid flow hole 37. Inside the third liquid flow hole 34 near its bottom end, a first liquid check valve 310 is installed, and inside the fourth liquid flow hole 37, a second liquid check valve 311 is installed. The liquid reserved cavity 35 and the first liquid flow hole 15 are connected through a water supply hose 36. Inside the liquid compression chamber 33, there is a piston body 38 that can move along its axis. On the upper surface of the piston body 38, a longitudinal movable rod 39 passing through the rod body perforation 23 is fixedly installed. The top end of the longitudinal movable rod 39 is fixedly installed inside the rod body fixing groove 213. The first liquid check valve 310 and the second liquid check valve 311 can control the entry of external liquid along the fourth liquid flow hole 37 and then discharge it into the liquid reserved cavity 35 through the third liquid flow hole 34.

[0035] When in use, the No. 4 liquid flow hole 37 is connected to a drain outlet storing clean water through a pipeline, and then the filler for growing vegetables is filled in the interior of each cultivation pool 17, and then the vegetable seeds are planted in the filler. By rotating the No. 1 rotating frame 11 and the No. 2 rotating frame 12, multiple cultivation boxes 16 can be rotated around the axis line of the No. 1 docking plate 111 until the cultivation box 16 is rotated to a suitable position. During the rotation process, due to the presence of the weight block 112, the cultivation box 16 will always remain in a horizontal state. When the No. 1 rotating frame 11 rotates in a certain direction, the gear 27 will rotate accordingly. Due to the meshing effect of the tooth structure, the gear bar 212 will produce a longitudinal movement phenomenon. By controlling the rotation direction of the No. 1 rotating frame 11, the longitudinal movement direction of the gear bar 212 can be controlled. When it moves to a suitable angle, the rotation of the No. 1 rotating frame is canceled. 11, due to the elastic strength of the coil spring 210, the brake plate 211 produces a friction phenomenon on the gear bar 212, and the maximum static friction force in the friction phenomenon is sufficient to keep the No. 1 rotating frame 11 stationary, and will keep each incubator 16 stationary. During the longitudinal movement, the gear bar 212 will drive the piston body 38 to produce a longitudinal movement effect. At this time, the space below the piston body 38 will change, thereby sucking the clean water in the water reservoir into the liquid compression chamber 33 and the No. 3 liquid flow hole 34, and then pressing the clean water located in the liquid compression chamber 33 and the No. 3 liquid flow hole 34 into the liquid reserved cavity 35. Finally, the clean water will enter the No. 1 liquid flow hole 15 through the water supply hose 36, and then enter the filler through each annular liquid flow hole 18 and the irrigation hole 19 to supply water to the vegetable seeds in the filler.
