[0002] Korean pine is a high-quality tree species with good ornamental and economic value. The grafting and management techniques of Korean pine play a vital role in the growth and development of Korean pine. Grafting is the process of combining the tissues of two different plants and growing them together. Through grafting technology, different varieties of Korean pine can be combined to increase the diversity of tree species and breed excellent varieties.

The present invention relates to the technical field of planting equipment, and specifically, to a planting device for grafted red pine container seedlings. The technical problem to be solved by the present invention is to provide a planting device for grafted red pine container seedlings to facilitate red pine grafting and transplanting.

[0004] The prior art of the above patent can also realize the planting of red pine container seedlings. However, the prior art does not take into account the watering situation during the planting process. The prior art requires a lot of manual participation. After the planting is completed, it is necessary to manually bury the soil and water. During the manual watering process, the water flow is only on the surface and may not reach the deep planting area, resulting in the watering not achieving the expected effect. It may make it difficult for the red pine seedlings to survive. Secondly, manual watering cannot control the amount of water well. While wasting water resources, excessive watering of the red pine seedlings may also make it difficult for the red pine seedlings to survive. Thirdly, after planting, the soil in the planting pit needs to be pressed and compacted manually, which increases labor costs. Summary of the invention

The retractable soil-covering frame can avoid scratches between the branches and trunks of the red pine seedlings, thereby preventing the soil-covering frame from damaging the red pine seedlings during the soil-covering process. In the process of covering the soil by the soil-covering frame, the tilted red pine seedlings are pushed toward the inside of the outer tube through the arc-shaped bars, again avoiding the soil-covering frame from causing damage to the red pine seedlings when the red pine seedlings tilt.

A cylinder 42 is arranged at the front and rear of the inner cylinder 41, and a driving plate 43 is fixedly installed on the output end of the cylinder 42. An outer cylinder 44 is fixedly installed between the two driving plates 43. The outer cylinder 44 is slidably sleeved on the inner cylinder 41, and an annular groove is provided in the outer cylinder 44. A watering component 45 is provided in the annular groove. A uniform soil covering component 46 is provided at the lower end of the outer cylinder 44. A conductive groove is provided on the rear side of the outer cylinder 44, and an insulating member 47 that can slide forward and backward is provided in the conductive groove. The insulating member 47 cooperates with the water injection mechanism 2, and the insulating member 47 and the conductive groove are elastically connected. A conductive head is provided at the right end of the insulating member 47.

[0029] In the above technical scheme, the Korean pine seedlings to be planted are piled in the placement frame 12, and then the workers transfer the single Korean pine seedlings to the discharge mechanism 3 in turn. The crawler 11 drives the placement frame 12, the water injection mechanism 2, the discharge mechanism 3, and the planting mechanism 4 to move forward through the frame 1, and the planting mechanism 4 moves to the top of the planting pit (the pit is excavated in advance). Then, the cylinder 42 drives the outer cylinder 44 to move downward through the driving plate 43, and the watering component 45 moves downward with the outer cylinder 44. When the watering component 45 reaches the water outlet 4848 position, the watering component 45 is opened, and the water in the annular groove is poured into the planting pit from the lower port of the inner cylinder 41 for the first watering operation. When the water level drops by half, the first watering operation is completed. Then, the discharge mechanism 3 starts and drives the Korean pine seedlings. It moves to the top of the inner cylinder 41, and then the Korean pine seedlings pass through the inner cylinder 41 from the discharge mechanism 3 and fall into the planting pit, and the soil-covering component 46 starts to perform the soil-burying operation. During the soil-burying operation of the soil-covering component 46, the soil-covering component 46 intermittently squeezes the watering component 45 to open the second water outlet 49, thereby realizing the secondary watering operation during the soil-burying process, and, during the soil-burying process, the soil-covering component 46 presses and compacts the soil. After the soil-burying is completed, the cylinder 42 drives the outer cylinder 44 to move upward through the driving plate 43, and the synchronously moving insulating part 47 connects the circuit of the water injection mechanism 2, and the water injection mechanism 2 injects water into the annular groove to replenish the water source. Then the track 11 drives the frame 1 to continue to move forward to the top of the next planting pit, thereby realizing the continuous planting operation of the Korean pine seedlings.

[0030] See also Figure 3 As shown, as the preferred technical solution of this embodiment, the discharge mechanism 3 includes a baffle 32, a turntable 33 and a placement cylinder 34. The baffle 32 is fixedly installed on the upper end of the bracket 13. The baffle 32 is an annular structure. A rotatable turntable 33 is installed in the baffle 32. A through groove corresponding to the inner cylinder 41 is opened directly behind the baffle 32. The turntable 33 is provided with uniform discharge ports along its circumference. The turntable 33 is an electric turntable. A placement cylinder 34 corresponding to the discharge port is fixedly installed on the turntable 33.

[0031] In the above technical scheme, as the planting mechanism 4 moves to the top of the planting pit, when the annular groove completes the first watering operation, the turntable 33 starts to drive the placement tube 34 to rotate clockwise. When the placement tube 34 rotates to the top of the through groove, the red pine seedlings in the placement tube 34 pass through the through groove and pass through the inner tube 41 and fall into the planting pit.

[0032] See also Figure 2 and Figure 3 As shown, as the preferred technical solution of this embodiment, the water injection mechanism 2 includes a water storage frame 20, a vacuum plate 21, an air bag 22, a power strip 23, a mounting plate 24, a battery pack 25 and an air pump 26. The water storage frame 20 is fixedly installed at the lower end of the bracket 13. A vacuum plate 21 that can slide up and down is arranged in the water storage frame 20. An air bag 22 is arranged below the vacuum plate 21. Two power strips 23 are fixedly installed on the side wall of the bracket 13. An air pump 26 is fixedly installed on the left end of the bracket 13 through the mounting plate 24. The air pump 26, the power strip 23 and the battery pack 25 arranged on the bracket 13 are electrically connected, and the air pump 26 and the air bag 22 are connected through a connecting pipe.

[0033] In the above technical scheme, after the planting of Korean pine seedlings is completed, the cylinder 42 drives the outer cylinder 44 to move upward through the driving plate 43, and the insulating member 47 moves upward synchronously, and the conductive head is in contact with the power strip 23, so that the circuit between the air pump 26, the power strip 23, and the battery pack 25 is connected, and the air pump 26 starts to inject air into the air bag 22. The air bag 22 is expanded by the air pressure, thereby pushing the vacuum plate 21 to move upward, and squeezing the water in the water frame 20 into the annular groove by squeezing. When the water in the annular groove is filled, the watering assembly 45 is squeezed to block the water inlet 40 of the annular groove and stop injecting water into the annular groove. When the cylinder 42 drives the outer cylinder 44 to move downward to the lowest point through the driving plate 43, the conductive head is separated from the power strip 23. At this time, the circuit between the air pump 26, the power strip 23, and the battery pack 25 is disconnected, and water injection into the annular groove is stopped, blocking the source of water in the annular groove, ensuring that the amount of water for each irrigation is uniform.

[0034] See also Figure 3 , Figure 4 , Figure 5 and Figure 7 As shown, as the preferred technical scheme of this embodiment, the watering assembly 45 includes a gravity ring 451, a blocking unit 452, a ring blocking unit 453, a locking piece 454 and a locking unit 455, a gravity ring 451 which can slide up and down is arranged in the annular groove, a symmetrical through hole is opened on the inner side of the annular groove, a blocking unit 452 is arranged in the through hole, the blocking unit 452 cooperates with the water outlet 4848, a ring blocking unit 453 is arranged at the lower end of the annular groove, a symmetrical locking groove is arranged on the outer side of the annular groove, a locking piece 454 which can slide back and forth is arranged in the locking groove, the locking piece 454 is a U-shaped structure, an extrusion head which cooperates with the gravity ring 451 is arranged on the inner end face of the upper part of the locking piece 454, an inclined surface which cooperates with the ring blocking unit 453 is arranged on the inner end face of the lower part of the locking piece 454, and a locking unit 455 which cooperates with the gravity ring 451 is arranged at the water inlet 40 of the annular groove.

[0035] In the above technical solution, when the outer cylinder 44 moves downward and drives the blocking unit 452 to move to the water outlet 4848, the blocking unit 452 opens, and the gravity ring 451 descends under the action of gravity. The gravity ring 451 squeezes the water inside the annular groove to make it flow out from the water outlet 4848 and pour into the planting pit. As the water level in the annular groove drops by half, the gravity ring 451 drops to contact and squeeze the squeezing locking member 454, and the locking member 454 is squeezed to move outward, thereby stopping the locking of the annular blocking unit 453. After waiting for the Korean pine seedling to fall into the planting pit, the soil covering component 46 is started, and the soil covering component 46 rotates through During the planting process, the soil around the planting pit is buried into the pit. At the same time, the rotating soil-covering component 46 intermittently squeezes the annular plugging unit 453 to move upward. The upward moving annular plugging unit 453 opens the water outlet 49, and the water in the annular groove flows out from the water outlet 49, thereby realizing the soil covering work and secondary watering of the red pine seedlings. After the planting is completed, the outer cylinder 44 moves upward, the water injection mechanism 2 is triggered and water is re-injected into the annular groove, and the gravity ring 451 moves upward under the buoyancy (and pressure) of the water flow. When the annular groove is full, the gravity ring 451 squeezes the locking unit 455 to block the water inlet 40 of the annular groove, thereby stopping the water injection.

[0036] See also Figure 5 and Figure 6As shown, the blocking unit 452 includes a slide cylinder 4521, a sleeve plate 4523, a slide rod 4524, a spring 4525 and a flap 4526. The slide cylinder 4521 is fixedly installed in the through hole, the sleeve plate 4523 is fixedly installed in the through hole, a slidable slide rod 4524 is arranged in the sleeve plate 4523, a spring 4525 is connected between the slide rod 4524 and the sleeve plate 4523, and when the flap 4526 does not reach the position of the first water outlet 4848, the outer side of the slide rod 4524 blocks the outer side of the slide cylinder 4521, and a spring 4525 is installed at the inner end of the through hole through a pin shaft. The flap 4526 rotates, and the flap 4526 is connected to the through hole by a torque spring. The diameter of the water outlet 4848 is larger than the diameter of the flap 4526. The elasticity of the torque spring is moderate. When the red pine seedlings fall into the planting pit, since the red pine seedlings themselves are heavier, the flap 4526 (the elastic force of the torque spring) will not hinder the falling of the red pine seedlings. When the red pine seedlings fall, they smoothly squeeze the flap 4526 to flip it, so that it can pass smoothly. In addition, the flipped flap 4526 blocks the water outlet 4848 to prevent the soil carried by the roots of the red pine seedlings from entering the water outlet 4848 and causing blockage.

[0037] In the above technical scheme, when the outer cylinder 44 moves downward and drives the flap 4526 to move to the position of water outlet 1 4848, the flap 4526 flips inward under the action of the torque spring, and the slide bar 4524 moves inward under the action of spring 2 4525. The slide bar 4524 stops blocking the outer opening of the slide cylinder 4521, and the water in the annular groove can flow into the planting pit through the slide cylinder 4521. When the red pine seedlings are planted, the outer cylinder 44 moves upward, and the flap 4526 is squeezed and reset by the inner cylinder 41, and at the same time drives the slide cylinder 4521 and the slide bar 4524 to reset.

[0038] See also Figure 4 , Figure 5 and Fig.10 As shown, the annular blocking unit 453 includes a sliding ring 4531 and an ejector 4535. The sliding ring 4531 is provided at the inner lower end of the annular groove. The lower end of the annular groove is provided with a water outlet 49 corresponding to the soil-covering component 46. The lower end of the sliding ring 4531 is fixedly installed with an ejector 4535 inserted into the inside of the water outlet 49. The lower end of the ejector 4535 is squeezed and fitted with the soil-covering component 46. The outer diameter of the ejector 4535 is much smaller than the inner diameter of the water outlet 49, thereby allowing water to flow through. The cross-sectional width of the sliding ring 4531 is larger than the inner diameter of the water outlet 49, thereby achieving a sealing effect on the water outlet 49. When the sliding ring 4531 is lifted up, water can flow out of the water outlet 49, and the ejector 4535 will not cause any obstruction.

[0039] In the above technical solution, when the red pine seedlings fall into the planting pit, the soil-covering assembly 46 starts to cover the soil. During the rotation of the soil-covering assembly 46, the ejection member 4535 is squeezed to move upward, and the sliding ring 4531 moves upward synchronously. The sliding ring 4531 stops blocking the water outlet 49, and the remaining water in the annular groove flows out from the water outlet 49 for secondary watering operation.

[0040] See also Figure 3 and Figure 4 As shown, the locking unit 455 includes a cross bar 4551, a vertical bar 4552 and a U-shaped part 4553. A locking groove is provided on the right side of the annular groove, and the locking groove is connected with the water inlet 40 of the annular groove. A cross bar 4551 that can slide left and right is arranged in the locking groove, and the cross bar 4551 and the locking groove are elastically connected. The left end face of the cross bar 4551 is squeezed and fitted with the gravity ring 451. A vertical bar 4552 that can slide up and down is arranged in the locking groove, and the vertical bar 4552 and the locking groove are elastically connected. The upper end face of the vertical bar 4552 is squeezed and fitted with the right end face of the cross bar 4551. A card slot is provided on the vertical bar 4552, and a U-shaped groove connected with the locking groove is provided in the outer sleeve. A U-shaped part 4553 that can slide left and right is arranged in the U-shaped groove, and the left end face of the U-shaped part 4553 is arranged as an inclined surface, and the U-shaped part 4553 and the U-shaped groove are elastically connected.

[0041] In the above technical solution, as the water in the annular groove flows out, the gravity ring 451 moves downward to the lowest point. At this time, the gravity ring 451 squeezes the U-shaped piece 4553 to move forward, and the U-shaped piece 4553 stops limiting the vertical rod 4552. The vertical rod 4552 moves upward under the elastic action to open the water inlet 40 of the annular groove (because the gravity ring 451 is at the lowest point, the gravity ring 451 does not squeeze the cross bar 4551. Therefore, the cross bar 4551 is outside the locking groove under the elastic action at this time). When the Korean pine seedlings are planted, as the outer cylinder 44 moves upward, the water injection mechanism 2 injects water into the annular groove, and the gravity ring 451 rises (the rising gravity ring 451 no longer squeezes the U-shaped piece 4553, Therefore, the U-shaped part 4553 has a tendency to reset under the action of elasticity, but at this time the vertical rod 4552 has already risen, and the slot and the U-shaped part 4553 are in a misaligned state. Therefore, the U-shaped part 4553 cannot reset). As the water in the annular groove is filled again, the gravity ring 451 moves upward to the highest point, the gravity ring 451 squeezes the cross bar 4551 to move forward, and the forward-moving cross bar 4551 squeezes the vertical rod 4552 to move downward to re-block the water inlet 40 of the annular groove. At the same time, the U-shaped part 4553 corresponds to the position of the slot, and the U-shaped part 4553 enters the slot to limit the vertical rod 4552 again. When the water in the subsequent annular groove flows out, the gravity ring 451 drops again, and this cycle repeats.

[0042] See also Figure 8 and Fig. 9As shown, the soil covering assembly 46 includes a guide plate 461, an electric rotating rod 462, a support frame 463, a sliding frame 464, a soil covering frame 465, an arc strip 466, a sliding rod 467, a protruding block 468 and a soil rolling plate 469. The lower end of the outer cylinder 44 is fixedly mounted with a uniform guide plate 461, and a guide groove 460 is provided on the lower end surface of the guide plate 461. The inner side of the guide groove 460 is an elliptical arc groove, and the outer side of the guide groove 460 is a circular arc groove. The lower end of the guide plate 461 is mounted with an electric rotating rod 462, and the guide plate 461 and the electric rotating rod 462 are eccentrically arranged (such as Figure 8 As shown in the figure, a support frame 463 is installed on the electric rotating rod 462, a slidable sliding frame 464 is arranged inside the support frame 463, a soil covering frame 465 is fixedly installed on the outer end surface of the sliding frame 464, an arc strip 466 is connected between the upper end outer side of the soil covering frame 465 and the upper end inner side of the support frame 463, and the arc strip 466 is made of spring sheet material. If the red pine seedlings tilt when falling into the planting pit, the arc strip 466 can advance the branches and trunks of the red pine seedlings during the soil covering process. Pushed inward to prevent the soil covering frame 465 from damaging the branches of the red pine seedlings during the soil covering process, a vertical groove is opened in the sliding frame 464, and a sliding rod 467 that can slide up and down is arranged in the vertical groove. The sliding rod 467 and the vertical groove are elastically connected, and the upper end of the sliding rod 467 slides in the guide groove 460. The inner end of the guide groove 460 is fixedly installed with a raised block 468 that is squeezed and matched with the sliding rod 467, and the lower end of the sliding rod 467 is fixedly installed with a soil rolling plate 469.

[0043] In the above technical scheme, after the Korean pine seedlings fall into the pit, the electric rotating rod 462 starts and drives the support frame 463 to rotate clockwise, and the sliding frame 464, the soil covering frame 465, the arc bar 466, the sliding rod 467, and the soil rolling plate 469 rotate synchronously. When the support frame 463 rotates to the outside of the outer cylinder 44, the sliding rod 467 is in the arc groove. At this time, the sliding rod 467 and the arc groove work together to make the soil covering frame 465 in the outermost position. As the support frame 463 rotates inwardly, the sliding rod 467 enters the elliptical arc groove and moves. Under the action of the sliding rod 467 and the elliptical arc groove, the soil covering frame 465 shrinks toward the inside of the support frame 463, thereby gathering the soil at the edge of the planting pit into the planting pit, and collecting The contracted soil-covering frame 465 causes the arc-shaped bar 466 to tighten and deform, and the arc-shaped bar 466 first pushes the branches of the Korean pine seedlings inward to prevent the soil-covering frame 465 from damaging the branches of the Korean pine seedlings. The gradual contraction of the soil-covering frame 465 when moving inward also avoids scratches between the Korean pine seedlings and prevents damage to the Korean pine seedlings. On the other hand, as the sliding rod 467 slides inside the guide groove 460, when the sliding rod 467 moves to contact the raised block 468, the raised block 468 squeezes the sliding rod 467 to move downward, and the soil-rolling plate 469 moves downward synchronously. The downward-moving soil-rolling plate 469 presses and compacts the soil around the Korean pine seedlings to prevent the Korean pine seedlings from tilting due to loose soil after planting.

[0044] Working principle: Step 1: Arrangement: Place the Korean pine seedlings to be planted in the placement frame 12, and the frame 1 drives the support 13, the water injection mechanism 2, the material discharge mechanism 3, and the planting mechanism 4 to move forward through the crawler 11 until the planting mechanism 4 moves to the top of the planting pit; Step 2: One-time watering: the outer cylinder 44 moves downward and drives the blocking unit 452 to move to the position of the water outlet 1 4848, the blocking unit 452 stops being limited and opened, and the water in the upper part of the annular groove flows into the bottom of the pit from the water outlet 1 4848; Step 3: Soil covering and secondary watering: The discharge mechanism 3 drives the Korean pine seedling to rotate to the top of the pit and fall into it, and then the soil covering frame 465 covers the soil at the edge of the planting pit into the pit. At the same time, the support frame 463 squeezes the ejector 4535 to move upward, and the water outlet 49 is opened for secondary watering. When the soil covering frame 465 rotates to the inside, the soil rolling plate 469 is triggered to press and compact the soil around the trunk of the Korean pine seedling; Step 4: After planting, refill with water: The crawler 11 drives the bracket 13 to move forward, preparing to plant the next planting pit. During this process, the water injection mechanism 2 injects water into the annular groove to fill it.
