Description

Technical Field

[0001] This invention relates to the field of seedling transplanting devices, specifically to a potato seedling transplanting device. Background Technology

[0002] Potatoes, as an important crop, are widely cultivated around the world, and their yield and quality are closely related to planting techniques and equipment. In traditional potato cultivation, seedling raising and transplanting are usually two separate processes. Seedlings typically need to grow to a suitable height and health condition in a specific seedling environment before being transplanted to the field manually or mechanically. However, this traditional planting method has many shortcomings.

[0003] Most existing potato transplanting equipment focuses on the transplanting operation itself and lacks a design for temporary seedling storage. The lack of an effective connection mechanism between seedling raising and transplanting makes the planting process inefficient, increases the workload of manual handling and management, and may also damage seedlings, reducing planting efficiency and quality.

[0004] Furthermore, with the continuous improvement of agricultural mechanization, growers' demand for automated and integrated equipment is increasing. Existing equipment still has significant room for improvement in terms of functional integration, especially in achieving integrated storage and transplanting operations, where there are obvious technological gaps.

[0005] Therefore, a potato seedling transplanting device is needed to solve the above problems. Summary of the Invention

[0006] To address the aforementioned problem, namely the insufficient efficiency of existing potato transplanting equipment, this invention provides a potato seedling transplanting device.

[0007] A potato seedling transplanting device includes an inner tube and an outer tube fixedly installed on the outer surface of the inner tube. The outer tube has multiple placement slots. A rotating ring is rotatably mounted inside the outer tube. The inner end of each placement slot is connected to the outer surface of the rotating ring. A carrying slot is formed on the outer surface of the rotating ring, and the bottom end of the carrying slot is connected to the inside of the inner tube. A slidable abutment ring is mounted on the bottom of the outer tube and is drivenly connected to the rotating ring. By drivingly connecting the sliding abutment ring to the rotating ring, when the bottom end of the inner tube is inserted into the soil, the abutment ring is lifted, thereby driving the rotating ring to rotate. When the rotating ring rotates to the placement slot, the seedling in the placement slot enters the carrying slot and then falls into the soil through the inner tube. This design makes the transplanting process convenient and effectively improves work efficiency.

[0008] Preferably, the outer tube is coaxially fixedly installed on the outer surface of the inner tube. The outer surface of the outer tube has multiple vertically distributed groove groups. Each groove group includes multiple placement grooves distributed at equal angles. The inner end of each groove group has a rotating cavity coaxially formed. The rotating ring is rotatably installed in the rotating cavity. By setting multiple placement grooves, multiple seedlings can be pre-placed in multiple placement grooves. This not only allows for multiple plantings after one placement, but also controls the quantitative drop of seedlings, improving the consistency of seedling transplanting.

[0009] Preferably, the outer surface of the rotating ring is provided with a carrying groove, the bottom of the rotating cavity is provided with a drop angled hole, the drop angled hole and the placement groove are staggered, and a matching angled hole is provided through the inner tube wall, the top end of the matching angled hole is connected to the bottom end of the drop angled hole.

[0010] Preferably, a sealing plate is hinged to the outer end of the placement slot via a torsion spring shaft. An inner groove is formed on the inner side of the sealing plate. A push plate is slidably mounted inside the inner groove via a first abutment spring. A permanent magnet is fixedly mounted on the inner side of the push plate. An electromagnet is fixedly mounted inside the sealing plate and is electrically connected to an external power source. A slave sensor is fixedly mounted on the outer surface of the rotating ring, located directly above the carrying slot. Multiple master sensors matching the slave sensors are fixedly mounted on the side surface of the rotating cavity. These master sensors are located directly above the placement slots and are electrically connected to the electromagnet via an external controller. The push plate and the sealing plate are connected via... The third pull rope is connected; by setting a push plate on the inside of the sealing plate, and setting corresponding permanent magnets, electromagnets, slave sensors and master sensors, when the rotating ring rotates to the point where the slave sensor and one of the master sensors sense each other, the carrying slot is connected to the corresponding placement slot. At the same time, the electromagnet is energized and generates a repulsive force with the permanent magnet, pushing the push plate inward, thereby quickly pushing the seedling in the placement slot into the carrying slot. When the rotating ring continues to rotate to the point where the bottom of the carrying slot is connected to the drop angle hole, the seedling in the carrying slot enters the inner tube through the drop angle hole and the matching angle hole, and then falls into the soil. This setting facilitates planting at the same time as the seedling in the placement slot falls out, realizing the purpose of integrated storage and transplanting. The third pull rope can prevent the push plate from getting stuck in the carrying slot.

[0011] Preferably, a first toothed ring is coaxially fixedly mounted on the outer surface of the rotating ring near the top end. A driving cavity is vertically formed inside the outer tube, and a driving shaft is rotatably mounted inside the driving cavity. A second toothed ring is coaxially slidably mounted on the outer surface of the driving shaft, and the second toothed ring meshes with the first toothed ring. A first limiting groove is vertically formed on the outer surface of the driving shaft, and a first limiting slider is fixedly mounted on the inner surface of the second toothed ring. The first limiting slider slides within the first limiting groove. When the driving shaft rotates, it can drive the second toothed ring to rotate, thereby driving the rotating ring to rotate through the first toothed ring.

[0012] Preferably, a lifting ring is slidably mounted on the outer surface of the drive shaft, and a second limiting slider is fixedly mounted on the outer surface of the lifting ring. A second limiting groove is formed on the side of the drive cavity, and the outer end of the second limiting slider slides within the second limiting groove. The upper surface of the lifting ring is connected to the top of the drive cavity via a second abutting spring. A lifting groove is coaxially formed on the upper surface of the second toothed ring, and the cross-section of the lifting groove is convex. A lifting rod is fixedly mounted on the lower surface of the lifting ring, and the bottom end of the lifting rod extends into the lifting groove and is fixedly mounted with an expansion plate. A first pull rope is fixedly mounted on the upper surface of the lifting ring, and the top end of the first pull rope extends above the outer tube. By setting the lifting ring, when the height of the second toothed ring needs to be adjusted, simply pull the first pull rope to raise the second toothed ring, and simply release the first pull rope; under the abutment of the second abutting spring, the second toothed ring will descend. This setting allows one second toothed ring to drive multiple first toothed rings separately, optimizing the internal structure and simplifying operation.

[0013] Preferably, the bottom of the outer tube has a sliding rod cavity, and a drive rod is slidably installed inside the sliding rod cavity via a third abutment spring. The bottom end of the drive rod is fixedly connected to the abutment ring. A toothed plate is integrally provided on the outer surface of one of the drive rods. A linkage shaft is rotatably installed inside the outer tube. A third toothed ring is coaxially rotatably installed on the outer surface of the linkage shaft. The third toothed ring meshes with the toothed plate. A driving bevel gear is coaxially fixedly installed at one end of the linkage shaft, and a driven bevel gear is coaxially fixedly installed at the bottom end of the drive shaft. The driven bevel gear meshes with the driving bevel gear.

[0014] Preferably, the inner surface of the third toothed ring is provided with a helical tooth groove, and the outer surface of the linkage shaft is provided with an inner constriction cavity. A helical tooth block is slidably installed inside the inner constriction cavity through a fourth abutment spring, and the helical tooth block abuts against the helical tooth groove. By setting a toothed plate on the drive rod and driving the toothed plate to the drive shaft through the linkage shaft, as the bottom end of the inner tube is inserted into the soil, the abutment ring is pushed upward after touching the ground, so that the toothed plate can drive the linkage shaft and the drive shaft to rotate through the third toothed ring. This allows the device to automatically drive the drive shaft, improving work efficiency. The helical tooth groove and helical tooth block are designed so that the drive rod can only drive the linkage shaft to rotate through the third toothed ring when sliding upward. When the drive rod slides downward, it cannot drive the linkage shaft to rotate through the third toothed ring.

[0015] Preferably, two mounting plates are symmetrically fixedly installed at the bottom end of the inner tube. Two mounting ears are rotatably installed on the inner side of each of the two mounting plates via pins. The two mounting ears are respectively fixedly connected to one end of two semi-rings. The ends of the two semi-rings are connected by tension springs. A tapered arc plate is fixedly installed at the bottom of each of the two semi-rings.

[0016] Preferably, a handle is fixedly installed at the top of the outer surface of the inner tube, a connecting plate is slidably installed inside the inner tube near the top, a pull rod is fixedly installed on the outer side of the connecting plate, the outer end of the pull rod extends to the outside of the inner tube, a second pull rope is fixedly installed at the middle position of the upper surface of each of the two semi-rings, the top of the second pull rope is connected to the pull rod, a rope hole is opened in the inner tube wall, and the second pull rope passes through the rope hole; by setting the conical arc plate, the closed conical arc plate can be inserted into the soil first, and after the seedling falls into the inside of the two conical arc plates, the pull rod is pulled upward, and the two conical arc plates can be separated by the second pull rope, so that the seedling falls into the soil.

[0017] The beneficial effects of this invention are as follows: 1. This invention connects a sliding top ring to a rotating ring. When the bottom of the inner tube is inserted into the soil, the top ring is lifted, thereby driving the rotating ring to rotate. When the rotating ring rotates to the placement trough, the seedling in the placement trough enters the carrying trough and then falls into the soil through the inner tube. This design makes the transplanting process convenient and effectively improves work efficiency.

[0018] 2. This invention features a push plate on the inner side of the sealing plate, along with corresponding permanent magnets, electromagnets, slave sensors, and master sensors. When the rotating ring rotates until the slave sensor and one of the master sensors sense each other, the carrying slot connects with the corresponding placement slot. Simultaneously, the electromagnet is energized, generating a repulsive force with the permanent magnet, pushing the push plate inward. This quickly pushes the seedlings in the placement slot into the carrying slot. When the rotating ring continues to rotate until the bottom of the carrying slot connects with the drop-off oblique hole, the seedlings in the carrying slot enter the inner tube through the drop-off oblique hole and the matching oblique hole, and then fall into the soil. This design facilitates simultaneous planting of seedlings falling out of the placement slot, achieving the integration of storage and transplanting.

[0019] 3. By setting a lifting ring, when the height of the second toothed ring needs to be adjusted, simply pull the first rope to raise the second toothed ring. Simply release the first rope, and the second toothed ring will descend under the pressure of the second supporting spring. This setting allows one second toothed ring to drive multiple first toothed rings separately, optimizing the internal structure and making operation simpler.

[0020] 4. This invention sets a toothed plate on the drive rod and drives the toothed plate to the drive shaft through the linkage shaft. As the bottom end of the inner tube is inserted into the soil, the top ring is pushed upward after it touches the ground, so that the toothed plate can drive the linkage shaft and the drive shaft to rotate through the third toothed ring. This allows the device to automatically drive the drive shaft and improve work efficiency. Attached Figure Description

[0023] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] like Figures 1-3 As shown in the figure, this invention discloses a potato seedling transplanting device, including an inner tube 1 and an outer tube 2 fixedly installed on the outer surface of the inner tube 1. Multiple placement slots 3 are provided on the outer tube 2. A rotating ring 4 is rotatably installed inside the outer tube 2. The inner end of the placement slot 3 is connected to the outer surface of the rotating ring 4. A carrying slot 5 is provided on the outer surface of the rotating ring 4. The bottom end of the carrying slot 5 is connected to the inside of the inner tube 1. A top-supporting ring 6 is slidably installed at the bottom of the outer tube 2, and the top-supporting ring 6 is drivenly connected to the rotating ring 4. By driving the sliding top-supporting ring 6 to the rotating ring 4, when the bottom end of the inner tube 1 is inserted into the soil, the top-supporting ring 6 is lifted, thereby driving the rotating ring 4 to rotate. When the rotating ring 4 rotates to the placement slot 3, the seedling in the placement slot 3 enters the carrying slot 5, and then falls into the soil through the inner tube 1. This design makes the transplanting process convenient and effectively improves work efficiency.

[0025] like Figure 3 and Figure 5As shown, the outer tube 2 is coaxially fixedly installed on the outer surface of the inner tube 1. The outer surface of the outer tube 2 has multiple vertically distributed groove groups. Each groove group includes multiple placement grooves 3 distributed at equal angles. The inner end of each groove group has a rotating cavity 7 coaxially opened. The rotating ring 4 is rotatably installed in the rotating cavity 7. By setting multiple placement grooves 3, multiple seedlings can be placed in multiple placement grooves 3 in advance. This not only allows for multiple plantings after one planting, but also controls the quantitative drop of seedlings, improving the consistency of seedling transplantation.

[0026] like Figure 5 and Figure 9 As shown, a carrying groove 5 is provided on the outer surface of the rotating ring 4, and a drop oblique hole 8 is provided at the bottom of the rotating cavity 7. The drop oblique hole 8 and the placement groove 3 are staggered. A matching oblique hole 9 is provided through the tube wall of the inner tube 1. The top end of the matching oblique hole 9 is connected to the bottom end of the drop oblique hole 8.

[0027] like Figure 1 and Figure 4 As shown, a sealing plate 11 is hinged to the outer end of the placement slot 3 via a torsion spring shaft 10. An inner groove is formed on the inner side of the sealing plate 11. A push plate 13 is slidably mounted inside the inner groove via a first abutment spring 12. A permanent magnet 14 is fixedly mounted on the inner side of the push plate 13. An electromagnet 15 is fixedly mounted inside the sealing plate 11 and is electrically connected to an external power source. A slave sensor 16 is fixedly mounted on the outer surface of the rotating ring 4, located directly above the carrying slot 5. Multiple master sensors 17 matching the slave sensors 16 are fixedly mounted on the side surface of the rotating cavity 7, each located directly above a different placement slot 3. All master sensors 17 are electrically connected to the electromagnet 15 via an external controller. The push plate 13 and the sealing plate 11 are connected via a third pull rope 18. The sealing plate 11... A push plate 13 is provided on the inner side of 1, and corresponding permanent magnets 14, electromagnets 15, slave sensors 16 and master sensors 17 are provided. When the rotating ring 4 rotates to the point where the slave sensor 16 and one of the master sensors 17 sense each other, the carrying groove 5 is connected to the corresponding placement groove 3. At the same time, the electromagnet 15 is energized and generates a repulsive force with the permanent magnet 14, pushing the push plate 13 inward, thereby quickly pushing the seedling in the placement groove 3 into the carrying groove 5. When the rotating ring 4 continues to rotate to the point where the bottom end of the carrying groove 5 is connected to the drop inclined hole 8, the seedling in the carrying groove 5 enters the inner tube 1 through the drop inclined hole 8 and the matching inclined hole 9, and then falls into the soil. This setting facilitates planting while the seedling in the placement groove 3 falls out, realizing the purpose of integrated storage and transplanting. The third pull rope 18 can prevent the push plate 13 from getting stuck in the carrying groove 5.

[0028] like Figures 5-7As shown, a first toothed ring 19 is coaxially fixedly installed on the outer surface of the rotating ring 4 near the top. A driving cavity is vertically opened inside the outer tube 2. A driving shaft 20 is rotatably installed inside the driving cavity. A second toothed ring 21 is coaxially slidably installed on the outer surface of the driving shaft 20. The second toothed ring 21 is meshed with the first toothed ring 19. A first limiting groove 22 is vertically opened on the outer surface of the driving shaft 20. A first limiting slider 23 is fixedly installed on the inner surface of the second toothed ring 21. The first limiting slider 23 slides in the first limiting groove 22. When the driving shaft 20 rotates, it can drive the second toothed ring 21 to rotate, thereby driving the rotating ring 4 to rotate through the first toothed ring 19.

[0029] like Figures 7-8 As shown, a lifting ring 24 is slidably mounted on the outer surface of the drive shaft 20, and a second limiting slider 25 is fixedly mounted on the outer surface of the lifting ring 24. A second limiting groove is provided on the side of the drive cavity, and the outer end of the second limiting slider 25 slides in the second limiting groove. The upper surface of the lifting ring 24 is connected to the top of the drive cavity through a second abutting spring 26. A lifting groove 27 is coaxially provided on the upper surface of the second toothed ring 21. The cross-section of the lifting groove 27 is convex. A lifting rod 28 is fixedly mounted on the lower surface of the lifting ring 24, and the bottom end of the lifting rod 28 extends into the lifting groove. An expansion plate 29 is fixedly installed inside the outer tube 27. A first pull rope 30 is fixedly installed on the upper surface of the lifting ring 24, with the top end of the first pull rope 30 extending above the outer tube 2. By setting the lifting ring 24, when it is necessary to adjust the height of the second toothed ring 21, simply pull the first pull rope 30 to raise the second toothed ring 21. Simply release the first pull rope 30, and the second toothed ring 21 will descend under the pressure of the second abutment spring 26. This setting allows one second toothed ring 21 to drive multiple first toothed rings 19 respectively, optimizing the internal structure and making the operation simpler.

[0030] like Figure 1 and Figure 12 As shown, a sliding rod cavity is provided at the bottom of the outer tube 2. A drive rod 32 is slidably installed inside the sliding rod cavity via a third abutting spring 31. The bottom end of the drive rod 32 is fixedly connected to the abutting ring 6. A toothed plate 33 is integrally provided on the outer surface of one of the drive rods 32. A linkage shaft 34 is rotatably installed inside the outer tube 2. A third toothed ring 35 is coaxially rotatably installed on the outer surface of the linkage shaft 34. The third toothed ring 35 is meshed with the toothed plate 33. A driving bevel gear 36 is coaxially fixedly installed at one end of the linkage shaft 34. A driven bevel gear 37 is coaxially fixedly installed at the bottom end of the drive shaft 20. The driven bevel gear 37 is meshed with the driving bevel gear 36.

[0031] like Figure 13As shown, the inner surface of the third toothed ring 35 is provided with a helical tooth groove 38, and the outer surface of the linkage shaft 34 is provided with an inner shrinkage cavity 39. The inner shrinkage cavity 39 is slidably mounted with a helical tooth block 41 through a fourth abutting spring 40, and the helical tooth block 41 abuts against the helical tooth groove 38. By setting a toothed plate 33 on the drive rod 32 and driving the toothed plate 33 to the drive shaft 20 through the linkage shaft 34, as the bottom end of the inner tube 1 is inserted into the soil, the abutting ring 6 is pushed upward after touching the ground, so that the toothed plate 33 can drive the linkage shaft 34 and the drive shaft 20 to rotate through the third toothed ring 35, so that the device can automatically drive the drive shaft 20, improving the working efficiency. The setting of the helical tooth groove 38 and the helical tooth block 41 means that the drive rod 32 can only drive the linkage shaft 34 to rotate through the third toothed ring 35 when sliding upward, and the drive rod 32 cannot drive the linkage shaft 34 to rotate through the third toothed ring 35 when sliding downward.

[0032] like Figures 9-10 As shown, two mounting plates 42 are symmetrically fixedly installed at the bottom of the inner tube 1. Two mounting ears 44 are rotatably installed on the inner side of each mounting plate 42 through a pin 43. The two mounting ears 44 are fixedly connected to one end of each of the two semi-rings 45. The ends of the two semi-rings 45 are connected by a tension spring 46. A conical arc plate 47 is fixedly installed at the bottom of each of the two semi-rings 45.

[0033] like Figure 1 and Figures 11-12 As shown, a handle 48 is fixedly installed at the top of the outer surface of the inner tube 1. A connecting plate 49 is slidably installed inside the inner tube 1 near the top. A pull rod 50 is fixedly installed on the outside of the connecting plate 49. The outer end of the pull rod 50 extends to the outside of the inner tube 1. A second pull rope 51 is fixedly installed at the middle position of the upper surface of each of the two semi-rings 45. The top of the second pull rope 51 is connected to the pull rod 50. A rope hole is opened in the inner tube wall of the inner tube 1, and the second pull rope 51 passes through the rope hole. By setting the conical arc plate 47, the closed conical arc plate 47 can be inserted into the soil first. After the seedling falls into the inside of the two conical arc plates 47, the pull rod 50 is pulled upward, and the two conical arc plates 47 can be separated by the second pull rope 51, so that the seedling falls into the soil.
