Through the cooperation of a bucket, a liquid guide valve, a water pipe, a slide plate, a sliding rod, a screw rod and a ground ring, a dynamic limit structure can be constructed, and each working node in the seedling planting process can be limited and regulated to improve the convenience and efficiency of seedling planting. On the one hand, the soil crushing depth and the seedling planting depth can be accurately limited and adjusted to achieve dynamic control of the seedling implantation depth, which can not only effectively reduce the fluctuation of the planting depth of the same batch of seedlings, improve the standardization of seedling planting, and effectively improve the planting effect of seedlings, but also can flexibly adjust the planting depth according to the type of seedlings and soil conditions. While improving the adaptability of the device and expanding the adaptability range of the device, it greatly improves the flexibility and reliability of seedling planting work, can provide a more stable survival basis for seedlings, effectively ensure the subsequent growth stability of seedlings, and greatly improve the survival rate of seedlings after planting;

[0025] On the other hand, it can cooperate with the protective seat, seedling seat, impeller box, runner, tooth plate, gear ring and toothed disc to perform multiple transformations and utilization of the driving force, and can accurately control the working progress of the impeller and the tiller. In addition, the limiting flow conversion effect of the outer barrel, inner plug, connecting rod, blocking rod, screw, conduit, outlet and inlet can perform multiple transformations and utilization of the driving force of the air pump, integrating loosening soil and digging holes, seedling delivery and transplanting, filling and compacting, and watering and fertilizing. It can use air flow pressure as the transmission medium to effectively connect various links in the seedling planting process, greatly improving the connection stability and compatibility and adaptability of various works in the seedling planting process. While improving the working stability of the device and improving the planting efficiency and planting effect of seedlings, it can effectively solve the problem of unstable connection between multiple power-driven devices.

On the other hand, it can cooperate with the inner rod, plug, clamping plate and sliding tube to accurately control the gathering and compaction of the soil, improve the compatibility and connection stability of the gathering and compaction work and the resetting work of the device, so that the planting can be more efficient and stable to continue the planting work, and improve the planting efficiency;

[0027] Through the coordination of the interface, swivel, side hole, air pipe, ring cavity, cover ring and top hole, the airflow driving force provided by the air pump can be further accurately converted. While improving the flexibility of driving force conversion and expanding the effective use range of driving force, the coordination between digging, planting seedlings and fixing seedlings can be further strengthened, making the planting process smoother. In addition, the liquid separation and diversion function of the sprinkler seat, nozzle, connecting pipe, liquid guide box, outer ring and liquid guide tube can realize synchronous watering, fertilization and pest control after the seedlings are planted in the land. While further enhancing the convenience of planting work and improving planting efficiency, the effectiveness of watering, fertilization and pest control can be fully guaranteed. In addition, the soil gathering and compacting effect of the soil pressure plate can use the water-seeking tendency of the seedling roots to guide the growth direction of the root system of the seedlings, which can greatly improve the stability of the subsequent growth of the seedlings and improve the survival rate of the seedlings.

[0028] To sum up, the device uses a single power source to realize the loosening of soil and digging holes, seedling delivery and planting, soil filling and compaction, watering and fertilizing, and pest control in the process of seedling planting. It can greatly improve the convenience of seedling planting, improve the compatibility and fluency of various seedling planting tasks, and can flexibly and accurately regulate the planting depth of seedlings. It can effectively accommodate the differences in soil and seedlings, greatly improve the survival rate of seedlings, and improve planting effects. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] After completing the above-mentioned loading and adjustment work, the cart 5 can be pushed, or the base 1 can be connected to an external traction mechanism to send the device to the area where the seedlings are to be planted in the forest farm. After arriving at the designated planting location, the screw rod 212 is rotated to make the ground ring 213 rise and fall accordingly under its drive, and the position of the ground ring 213 is adjusted. In the initial state, the bottom end of the ground ring 213 is flush with the bottom end of the tilling blade 205. At this time, the planting depth is the lifting distance of the slide plate 210. For the convenience of description, the lifting distance value of the slide plate 210 is referred to as the initial value below;

[0059] At this time, according to actual needs, the relative height of the ground ring 213 can be adjusted by the screw rod 212 to adaptively adjust the planting depth. When the required planting depth value is less than the initial value, the ground ring 213 is driven down by the screw rod 212. On the contrary, when the required planting depth value is greater than the initial value, the ground ring 213 is driven down by the screw rod 212. The specific value of the ground ring 213 rising and falling relative to the tiller blade 205 is the difference between the required planting depth value and the initial value. For the convenience of description, the difference between the required planting depth value and the initial value is called the compensation value.

[0060] After completing the above adjustment, the blocking rod 221 is rotated to make it rise and fall relative to the inner plug 219, and the length thereof exposed outside the outer barrel 218 is adjusted. When the required planting depth value is less than the initial value, the length is made equal to the difference between the initial value and the compensation value. When the required planting depth value is greater than the initial value, the length is made equal to the sum of the initial value and the compensation value.

[0061] Then, the screw rod 222 is rotated to drive it to rise and fall relative to the inner plug 219. In the initial state, the height difference between the position of the interface 306 and the position of the inlet 225 is the initial value. At this time, when the screw rod 222 is adjusted, when the required planting depth value is less than the initial value, the screw rod 222 is lowered relative to the inner plug 219, and the lowering value is the compensation value. On the contrary, the screw rod 222 is raised relative to the inner plug 219, and the rising value is the compensation value, that is, the relative raising and lowering value of the screw rod 222 is consistent with the relative raising and lowering value of the ground ring 213.

[0062] After completing the above adjustment work, the air pump 6 can be started to start the planting of seedlings. The air pump 6 draws external air and sends the airflow into the outer barrel 218 through the conduit 223. Then the airflow passes through the inlet 225 and the outlet 224 in sequence, and synchronously enters the space at the bottom of the support plate 3 and the wheel box 206 in the inner cavity of the straight tube 2 through another conduit 223. Then, under the pressure of the airflow, the impeller 204 will drive the seedling tube 203 to rotate, and the tiller 205 will also rotate accordingly. At the same time, under the pressure of the airflow, the support plate 3 will overcome the top air pressure and drag the column 4 to rise relative to the straight tube 2, so that the base 1 drives the seedling tube 203 and the tiller 205 to be pressed down as a whole;

[0063] When the required planting depth value is less than the initial value, after the above adjustment, the ground ring 213 will first contact the ground. After the ground ring 213 contacts the ground, the base 1 continues to press down, and the ground ring 213 will support the slide plate 210 relative to the bucket 207 through the screw rod 212 and the slide bar 211. When its rising value reaches the compensation value, the seedling tube 203 and the tilling knife 205 are in contact with the ground. At this time, as the base 1 continues to press down, and the seedling tube 203 and the tilling knife 205 rotate, the tilling knife 205 will cut and crush the ground, and the threaded part at the bottom of the seedling tube 203 will also be screwed into the ground. When the ground crushing depth reaches the required planting depth value, the rising height of the slide plate 210 relative to the bucket 207 reaches the initial value.

[0064] When the required planting depth value is greater than the initial value, the seedling tube 203 and the tiller blade 205 will first contact the ground, and then the base 1 will continue to press down. In addition, the seedling tube 203 and the tiller blade 205 will rotate, and the tiller blade 205 will cut and crush the ground. When the crushing depth of the ground reaches the compensation value, the ground ring 213 will contact the ground, and then the base 1 will continue to press down. The ground ring 213 will support the slide plate 210 relative to the bucket 207 through the screw rod 212 and the slide bar 211. When its rising value reaches the initial value, the ground crushing depth reaches the required planting depth value;

[0065] In the aforementioned process of injecting culture fluid into the water tank 8, under the guidance of the liquid guide valve 208, the culture fluid will flow into the bucket 207 through the water pipe 209 connected to the water tank 8, and in the process of the slide plate 210 rising relative to the bucket 207, under the guidance of another liquid guide valve 208, the culture fluid in the bucket 207 will be pressed into the guard seat 201 through another water pipe 209, forcing the rotating wheel 214 to rotate under hydraulic drive. During the rotation of the rotating wheel 214, it will drive the toothed disc 217 to rotate through the toothed plate 215, forcing the gear ring 216 to drive the seedling seat 202 to deflect under the drive of the toothed disc 217;

[0066] During this process, the rotation angle of the wheel 214 corresponds to the rising value of the slide plate 210 relative to the bucket 207. When the rising value of the slide plate 210 relative to the bucket 207 reaches the initial value, the wheel 214 just rotates one circle, and under the transmission of the tooth plate 215 and the gear ring 216, the deflection angle of the seedling seat 202 just reaches the slot position of a seedling slot 2021. At this time, a seedling slot 2021 loaded with seedlings will deflect to the top of the seedling tube 203. The seedling will fall into the seedling tube 203 under the action of gravity, and slide down along the seedling tube 203 and insert into the ground. The insertion depth is the ground crushing depth, that is, the required planting depth.

[0067] At the same time, when the ground ring 213 rises, it will push the inner plug 219 along the outer barrel 218 to rise relative to the screw rod 222 through the connecting rod 220, and the blocking rod 221 will also rise accordingly. After the above adjustment, when the rising value of the slide plate 210 relative to the bucket 207 reaches the initial value, the interface 306 is just aligned with the inlet 225, and the screw rod 222 will cut off the connection between the outlet 224 and the inlet 225. At the same time, the blocking rod 221 will also retract into the inner part of the outer barrel 218;

[0068] At this time, the air flow delivered by the air pump 6 will pass through the inlet 225 and the interface 306 in sequence, enter the inner cavity of the screw 222, and pass through the side hole 308. Under the limitation of the rotating ring 307, it will enter the annular cavity 310 through the air pipe 309, and enter the lifting cylinder 302 through the top hole 312, pressing the arc plate 303, so that the arc plate 303 overcomes the bottom air pressure, and drags the soil pressing plate 305 downward through the hollow rod 304 to gather and compact the soil around the seedling. At the same time, the culture solution pressed into the seedling seat 202 will enter the liquid guide box 320 through the liquid guide tube 322, and flow into the watering seat 317 through the connecting pipe 319, and be sprayed out through each nozzle 318, and evenly sprinkled into the soil around the seedling;

[0069] Similarly, in the above process, after the blocking rod 221 is retracted into the outer barrel 218 and the air supply from the air pump 6 is lost, the support plate 3 will be reset accordingly under the action of the air pressure at the top of the support plate 3, and the air inside the straight tube 2 at the bottom of the support plate 3 will enter the outer barrel 218 through the conduit 223 and, after passing through the outlet 224, flow out from the hole at the bottom of the outer barrel 218 corresponding to the position of the blocking rod 221, and the base 1 will also drive the seedling tube 203 and the tilling knife 205 to gradually rise and reset;

[0070] As the soil pressing plate 305 is pressed down, when the arc plate 303 contacts the clamping plate 315, the arc plate 303 continues to press down, and it will drive the inner rod 313 to slide down through the clamping plate 315, forcing the plug 314 to drop synchronously under the drag of the inner rod 313, and finally separate from the top of the lifting cylinder 302. At this time, the airflow entering the lifting cylinder 302 from the top hole 312 will be discharged through the gap between the lifting cylinder 302 and the plug 314. After losing the air pressure support, the soil pressing plate 305 stops pressing down and gradually resets under the air pressure at the bottom of the arc plate 303, and then the plug 314 and the inner rod 313 will also reset accordingly;

[0071] After observing that the soil pressure plate 305 is no longer pressing down, the air pump 6 can be shut down, and then all parts of the device will be reset accordingly after losing the air pressure support. It should be added here that: in the process of the tiller blade 205 breaking the ground, the air inside the exhaust pipe 7 is filled and discharged through the air valve 73, and the air pressure on the plug 72 is changed, so that the air pressure required for the airflow delivered by the air pump 6 to be discharged from the wheel box 206 can be changed, and the airflow driving pressure in the process of the tiller blade 205 breaking the ground can be limited to adapt to the ground of different hardness, improve the efficiency of the device, and reduce the load of the device.
