[0008] Furthermore, the front end of the inner wall of the collecting bottom plate is a sloped structure.

[0009] Through the above technical solution, after the watering work, the water seeping from the culture mechanism will drip into the inside of the collecting bottom plate, and then the inside of the collecting bottom plate can be easily cleaned through the inclined structure at the front end.

[0010] Furthermore, the light panel assembly includes a connecting circuit board mounted on the top plate of the device, and a plurality of fill light strips are fixedly connected to the bottom of the connecting circuit board.

[0011] Through the above technical solution, the connected circuit board is powered on through the control component, and then the seedlings are illuminated by the light emitted by multiple fill light strips, so that the device can also provide lighting indoors, ensuring the normal growth of the plants.

[0012] Furthermore, the irrigation mechanism includes a water pump fixedly connected to the top of the device top plate and two pipe fixing buckles, the input end and output end of the water pump are respectively installed with connecting input pipes and output rigid pipes, the bottom of the output rigid pipe is fixedly connected with multiple connecting nozzles, and the two pipe fixing buckles are arranged at both ends of the outer wall of the output rigid pipe.

[0013] Through the above technical solution, the input pipe is connected to the water source, and driven by the driving motor, multiple culture tanks are driven to the top in turn, and the water pump flows water through the output hard pipe and multiple connecting nozzles to irrigate the culture tanks.

[0014] Furthermore, the rotating support driving mechanism includes a first support column, a rolling bushing is installed on the top inner wall of the first support column, a connecting shaft is provided on the inner wall of the rolling bushing, a first rotating frame and a transmission gear are fixedly connected on both sides of the connecting shaft, the first support column is fixedly connected to a motor mounting plate on the side close to the transmission gear, a driving motor is installed on the top of the motor mounting plate, a driving gear is fixedly connected to the output end of the driving motor, and a gear protective shell is fixedly connected between one side of the first support column and the motor mounting plate.

[0015] Through the above technical scheme, during the process of supplementary lighting and watering, the control component controls the driving motor to drive the driving gear to rotate, and then drives the transmission gear meshing with it, drives the first rotating frame to rotate through the connecting shaft, and finally makes the multiple culture mechanisms rotate continuously, so that the seedlings can be evenly illuminated, and drive the multiple culture mechanisms in turn to perform watering operations.

[0016] Furthermore, the rotation support limit mechanism includes a second support column, a rotation support shaft is provided on the top of one side of the second support column, and the outer wall of the rotation support shaft is respectively provided with a limit adjustment frame and a second rotation frame, the outer wall of the limit adjustment frame is fixedly connected with a fixed ear, and one side of the second rotation frame is respectively fixedly connected with an arc-shaped support sleeve and a plurality of limit sleeves, the inner walls of the plurality of limit sleeves are slidably connected with sliding tooth blocks, and one side of the plurality of sliding tooth blocks is fixedly connected with an adjusting round block, and a limit screw is passed through the second rotation frame, the arc support sleeve and the fixed ear, and a locking nut is spirally connected to the limit screw.

In this process, the limit adjustment frame rotates, and then drives the multiple adjustment round blocks through the multiple arc through holes on the limit adjustment frame to make the sliding gear block slide downward inside the limit sleeve, so that the sliding gear block can be disengaged from the limit gear, and then rotate the second rotating frame to drive the multiple culture mechanisms to rotate accordingly. Since the sliding gear block and the limit gear are disengaged, during rotation, the multiple culture tanks can keep their openings facing upward. When it is necessary to fix the multiple culture mechanisms to prevent them from shaking at will (such as culturing outdoors), the limit adjustment frame can be rotated to drive the multiple sliding gear blocks to expand outward until they are engaged with the corresponding limit gears, and finally the locking nut is rotated and locked, thereby achieving the fixation of the multiple culture tanks.

[0024] A plant cultivation device and method for a soil seed bank, characterized by comprising the following specific steps:

[0025] Step 1: Take out the seeds from the seed bank. In order to ensure the survival rate of the seeds, different methods of processing are required for different seeds before sowing. Suitable seedling substrates are filled in the interiors of multiple culture tanks. During the filling process, first, the locking nut is rotated to release the fixation between the limit adjustment frame and the second rotating frame, and then the limit adjustment frame is rotated to make the limit screw rotate to the other end of the arc-shaped support sleeve, and finally the locking nut is tightened in the reverse direction to fix the limit adjustment frame and the second rotating frame. In this process, the limit adjustment frame rotates, and then drives the multiple adjustment round blocks through the multiple arc-shaped through holes on the limit adjustment frame to make the sliding gear block slide downward inside the limit sleeve, so that the sliding gear block can be disengaged from the limit gear, and then the second rotating frame is rotated to drive the multiple culture mechanisms to rotate accordingly. Since the sliding gear block and the limit gear are disengaged, the multiple culture tanks can keep their openings facing upward during rotation;

[0026] Step 2: According to the size and characteristics of the seeds, select appropriate sowing depth and spacing in multiple culture tanks, cover the soil lightly after sowing, and maintain appropriate humidity. During the sowing and covering the soil, the second rotating frame is rotated to drive the multiple culture mechanisms to rotate, so as to achieve sequential sowing and covering the soil;

[0027] Step 3: After the seeds germinate and break through the soil, if the outdoor environment is suitable for plant survival, the two light panel assemblies in the device are removed, and then moved outdoors for cultivation through multiple universal wheels. If the outdoor environment is not suitable, two light panel assemblies are required for supplementary lighting while ensuring the temperature and humidity indoors. During the process of supplementary lighting after the two light panel assemblies are powered on, the driving motor drives the driving gear to rotate, and then drives the transmission gear meshing therewith, drives the first rotating frame to rotate through the connecting shaft, and finally makes the multiple cultivation mechanisms rotate continuously, so that the seedlings can be evenly illuminated;

[0028] Step 4: In the subsequent watering process, connect the input pipe to the water source. Driven by the driving motor, multiple culture tanks are driven to the top in turn. The water pump flows water through the output hard pipe and multiple connecting nozzles to irrigate the culture tanks.

[0029] The beneficial effects of the present invention are as follows: (1) By designing a light panel assembly and a rotating support driving mechanism, the present invention can illuminate the seedlings through the light panel assembly when cultivating indoors. At the same time, with the cooperation of the rotating support driving mechanism, the driving motor drives the driving gear to rotate, which in turn drives the transmission gear meshing therewith, and drives the first rotating frame to rotate through the connecting shaft, and finally causes multiple cultivation mechanisms to rotate continuously, so that the seedlings can be evenly illuminated, ensuring that the plant seedlings in multiple cultivation mechanisms are in the same growth environment; (2) By designing a rotating support limiting mechanism, the present invention can rotate the entire device when it is necessary to rotate the entire device. When the cam is in the position, the limit adjustment frame is rotated to make the limit screw rotate to the other end of the arc-shaped support sleeve, and finally the locking nut is tightened to fix the limit adjustment frame between the second rotating frame. At this time, multiple culture mechanisms can continue to rotate along with the rotating support driving mechanism and the rotating support limiting mechanism, and the openings of the culture troughs are always facing upward. When cultivating seedlings outdoors, the limit adjustment frame can be driven to expand multiple sliding gear blocks outward until they are engaged with the corresponding limit gears. Finally, the locking nut is rotated and locked, thereby fixing the multiple culture troughs to avoid shaking of the culture troughs outdoors. BRIEF DESCRIPTION OF THE DRAWINGS

During the filling process, firstly, the locking nut (711) is rotated to release the fixation between the limit adjustment frame (703) and the second rotating frame (704), and then the limit adjustment frame (703) is rotated to rotate the limit screw (710) to the other end of the arc support sleeve (709), and finally the locking nut (711) is tightened in the reverse direction to make the limit adjustment frame (703) and the second rotating frame (704) fixed. ), during which the limit adjustment frame (703) rotates, and then drives the multiple adjustment round blocks (708) through the multiple arc-shaped through holes on the limit adjustment frame (703), thereby causing the sliding tooth block (707) to slide downward inside the limit sleeve (706), so that the sliding tooth block (707) can be disengaged from the limit gear (803), and then the second rotating frame (704) is rotated to drive the multiple culture mechanisms (8) to rotate accordingly. Since the sliding tooth block (707) and the limit gear (803) are disengaged, the multiple culture tanks (801) can keep their openings facing upward during rotation; Step 2: According to the size and characteristics of the seeds, appropriate sowing depth and spacing are selected in the multiple culture grooves (801), and after sowing, the soil is lightly covered and maintained at an appropriate humidity. During the sowing and soil covering process, the second rotating frame (704) is rotated to drive the multiple culture mechanisms (8) to rotate, thereby achieving sequential sowing and soil covering work; Step 3: After the seeds germinate and break through the soil, if the outdoor environment is suitable for the survival of the seedlings, the two light panel assemblies (4) in the device are removed and then moved outdoors for cultivation through multiple universal wheels (10). If the outdoor environment is not suitable for the survival of the seedlings, the two light panel assemblies (4) are required to provide supplementary light while ensuring the temperature and humidity in the indoor cultivation. During the process of supplementary light after the two light panel assemblies (4) are powered on, the driving motor (607) drives the driving gear (608) to rotate, thereby driving the transmission gear (605) meshing therewith, and driving the first rotating frame (604) to rotate through the connecting shaft (603), and finally causing the multiple cultivation mechanisms (8) to rotate continuously so that the seedlings can be evenly illuminated; Step 4: During the subsequent irrigation process, the connecting input pipe (503) is connected to the water source, and driven by the driving motor (607), multiple culture tanks (801) are driven to the top in sequence, and the water pump (501) flows water through the output hard pipe (504) and multiple connecting nozzles (505) to irrigate the culture tanks (801).
