Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0033] Example 1: A mobile vegetable seedling bed includes a cultivation rack 1. A water tank 2 is fixedly connected to the left end of the cultivation rack 1, and a fixed frame 3 is fixedly connected to the top of the cultivation rack 1. Adjusting rods 7 are fixedly connected to the inner walls of both ends of the fixed frame 3. Several sliding groove shells 8 are slidably connected to the outer walls of the adjusting rods 7. A cultivation bed 17 is connected to one end of each sliding groove shell 8 via an adjusting assembly. The adjusting assembly includes adjusting rings 9 rotatably connected to the top of each sliding groove shell 8. Several screw rods 24 are rotatably connected to the inner wall of each sliding groove shell 8. Extrusion blocks 25 are threadedly connected to the outer walls of each screw rod 24. The bottom ends of the extrusion blocks 25 are slidably connected to the inner wall of the sliding groove shell 8. Driven gears 23 are fixedly connected to the opposite ends of each screw rod 24. Face gears 28 are fixedly connected to the bottom ends of each adjusting ring 9. The driven gears 23 and face gears 28 are meshed. Connecting pipes 15 are fixedly connected to one end of each sliding groove shell 8. Each of the two tubes 15 has a fixed tube 16 rotatably connected to one end of each tube. The fixed tube 16 is fixedly connected to the left and right ends of the culture bed 17. Each of the two tubes 15 has a first engagement wheel 20 fixedly connected to the inner wall of each tube 15. Each of the two tubes 16 has a second engagement wheel 21 slidably connected to the inner wall of each tube 16. Each of the two engagement wheels 21 has a return spring 22 fixedly connected to one end of each engagement wheel 21. The other end of the return spring 22 is fixedly connected to the left and right sides of the culture bed 17.

[0034] Specifically: During the operation of the mobile vegetable seedling bed, when it is necessary to adjust the light-receiving position of the seedling bed 17 according to the plant growth requirements, the height is first adjusted: the operator rotates the adjusting ring 9 on the seedling bed frame, which drives the meshing face gear 28 to rotate, and then the face gear 28 drives the driven gear 23 meshing with it to rotate; the driven gear 23 then drives the screw 24 coaxially mounted with it to rotate; the rotation of the screw 24 is converted into axial thrust, pushing the extrusion block 25 mounted on it to move away from the center (outward) along the screw axis; when the extrusion block 25 completely disengages from its original engagement...

[0035] After the groove is positioned, it disengages from the height-adjusting rod 7, releasing the locking state of the adjusting rod 7. At this time, the operator can smoothly slide the adjusting rod 7 or the corresponding lifting mechanism up and down as needed to achieve fine adjustment of the overall height of the cultivation bed 17. After the height adjustment is completed (or at the same time as the height adjustment), if it is necessary to optimize the light-receiving angle of the seedling bed, the angle adjustment is performed: the operator pulls the engagement wheel 21 installed on the fixed tube 16 outward, overcoming the internal elasticity and compressing the return spring 22; the engagement wheel 21 then shifts axially, and its tooth surface or meshing structure disengages from the engagement wheel 20 fixed on the support shaft or connecting shaft of the cultivation bed 17; the support structure of the cultivation bed 17, which has been released from the meshing lock, can rotate freely in the axial direction at its connection point, especially the connecting tube 15 connected to the base or bracket; by rotating the cultivation bed 17 itself (usually rotating around the axis of the connecting tube 15), the tilt angle of the entire seedling bed platform can be flexibly adjusted. This ingenious combination of height and angle adjustment functions allows the mobile vegetable seedling bed to precisely adjust the three-dimensional spatial position and orientation of the seedlings in the seedling trays or plug trays on the cultivation bed 17 according to the dynamic changes in the sun's position or the light distribution in the seedling area. This maximizes the optimal light intensity and angle for the vegetable seeds and seedlings, effectively reducing the adverse effects of weak light and shade, and significantly improving the light energy utilization efficiency of the entire seedling device, as well as the cultivation efficiency and seedling quality of the vegetables.

[0036] Example 2: An adjusting frame 4 is fixedly connected to the rear end of the fixed frame 3. A motor 5 is fixedly connected to the left side of the top of the adjusting frame 4, and a motor 6 is fixedly connected to the right side of the top of the adjusting frame 4. The driving end of the motor 6 is connected to a spray head 19 via a spray assembly. The spray assembly includes a screw 13 fixedly connected to the driving end of the motor 6. A movable frame 14 is threadedly connected to the outer wall of the screw 13. The outer wall of the spray head 19 is slidably connected to the inner wall of the movable frame 14. A transmission column 10 is fixedly connected to the driving end of the motor 5. A worm 26 is slidably connected to the outer wall of the transmission column 10. The outer wall of the worm 26 is rotatably connected to the inner wall of the movable frame 14. A screw 18 is rotatably connected to the inner wall of the movable frame 14. A worm wheel 27 is fixedly connected to the left end of the screw 18. The worm 26 and the worm wheel 27 are meshed together.

[0037] Specifically: In the intelligent irrigation process of the mobile vegetable seedling bed, when precise control of the spray position is required to adapt to the needs of seedlings in different areas or at different growth stages, the operator starts the motor 6 responsible for vertical adjustment. Its output shaft directly drives the screw 13 to rotate. The rotation of the screw 13 converts the rotational motion into linear motion through the threaded joint, precisely driving the mobile frame 14 mounted on it to perform stable and smooth vertical displacement (i.e., height adjustment) along the precision guide groove or slide rail in the motor 5 body (or the guide mechanism rigidly connected to the motor 1). At the same time, when precise horizontal positioning of the spray area is required, the motor 5 located in the horizontal adjustment unit is started, and its power output drives the transmission column 10 connected to it to rotate. The rotation of the transmission column 10 is directly transmitted to the worm 26 located at the front end of the transmission chain. The worm wheel 27, which is precisely meshed with the worm 26, is then driven to rotate. Since the worm wheel 27 and the screw 18 are usually connected by coaxial fixed connection or direct drive, the rotation of the worm wheel 27 drives the screw 18. Synchronous rotation; the rotation of screw 18 drives the support or slider of the spray head 19 mounted on it via the threaded pair, allowing for precise and controllable lateral horizontal displacement on the matching transverse guide rail or guide rod; finally, the height adjustment of the moving frame 14 (and its components) driven by motor 6 is combined with the lateral displacement of the spray head 19 driven by motor 5, thus forming a flexible multi-axial (vertical + horizontal) position adjustment system. This significantly improves the spatial positioning capability of the spray head 19, enabling it to not only reach the vertical height of the target area but also accurately position itself to the horizontal coordinate point of the target location; more importantly, this design also typically allows for the integration of an angle fine-tuning mechanism (such as a universal joint or slewing bracket) on the mounting base of the spray head 19, or for multi-axial (tilt angle, azimuth angle) fine adjustment of the spray angle of the spray head 19 by adjusting the posture of the moving frame / slider, thereby enabling precise adjustment of the spray angle of the spray head 19 according to the cultivation bed 17 in a mobile vegetable seedling bed environment. The system can flexibly and accurately direct irrigation water to the target area based on the distribution density and row arrangement of seedlings in seed trays or seedlings, as well as the differentiated water requirements of different types of vegetable seedlings (such as leafy vegetables and solanaceous vegetables). This minimizes water waste and ineffective spraying, ensuring that each seedling receives timely, adequate, and uniform water nourishment, effectively improving water and fertilizer utilization.

[0038] Use efficiency and overall seedling success rate.

[0039] As one of the optimized structural designs for Example 1, as shown in Figure 1- Figure 6As shown, a water pump 11 is installed on the inner wall of the water tank 2. The output end of the water pump 11 is fixedly connected to a delivery pipe 12. The other end of the delivery pipe 12 is fixedly connected to the rear end of the spray head 19 and passes through it. When the water pump in the water tank 2 is controlled to pump water into the delivery pipe 12, the spray head 19 sprays water, thereby irrigating the seeds in the cultivation bed 17.

[0040] Working principle: After placing the seeds and potting soil on the cultivation bed 17, during sunlight exposure, when height adjustment is needed, rotating the adjusting ring 9 causes the face gear 28 to drive the driven gear 23, which in turn drives the screw 24 to rotate. This causes the screw 24 to move the pressing block 25 outward, disengaging it from the adjusting rod 7. This allows the cultivation bed 17 to be height adjusted. Pulling the engagement wheel 21 at the fixed tube 16 compresses the return spring 22, causing the engagement wheel 21 to disengage from the engagement wheel 20. This allows the cultivation bed 17 to rotate at the connecting tube 15, enabling angle adjustment. This allows the cultivation bed 17 to match the sunlight exposure position under height adjustment and angle rotation, improving the cultivation efficiency of the device.

[0041] When the water pump in the water tank 2 pumps water into the delivery pipe 12, the spray head 19 sprays water to irrigate the seeds in the cultivation bed 17. When the starter motor 6 drives the screw 13 to rotate, the screw 13 drives the moving frame 14 to adjust its height within the motor 5. When the starter motor 5 drives the transmission column 10 to rotate, it drives the worm gear 26 to rotate the worm wheel 27, thereby causing the screw 18 to drive the spray head 19 to move laterally. This allows the spray head 19 to be adjusted in multiple axial angles, facilitating accurate adjustment of the spray head 19.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
