Description

Technical Field

[0001] This invention relates to the field of transplanting machinery technology, and in particular to a transplanting machine for planting strawberry seedlings. Background Technology

[0002] A strawberry seedling transplanter is an automated or semi-automated agricultural machine specifically designed for strawberry cultivation. It mainly consists of a seedling supply mechanism, a planting mechanism, and a drive mechanism, aiming to improve transplanting efficiency, reduce labor costs, and ensure the uniformity of seedlings.

[0003] For example, Chinese patent application CN218550625U discloses a strawberry seedling transplanting device for strawberry cultivation. This device, through the cooperation of a first U-shaped plate, a movable rod, and a second U-shaped plate, can push two arc-shaped inserts to tilt, thereby facilitating the transplanting of seedlings by workers. By driving the ring inserts to move according to the needs of use, the device is simple to operate and convenient to use, and does not require frequent cleaning of the attached soil, thus helping to improve the transplanting speed of seedlings. While existing strawberry seedling transplanting devices can improve planting efficiency to some extent, during the transplanting process, the strawberry seedlings need to be positioned so that the branches face the furrows on both sides. This allows the future flower clusters and fruit bunches to naturally droop towards the sides of the furrows, ensuring even fruit distribution, facilitating field management (such as fertilization and watering), enhancing ventilation and light penetration, reducing the risk of pests and diseases, and significantly improving harvesting convenience. However, existing transplanting devices cannot accurately position the strawberry branches towards the furrows during operation, thus affecting the precision of strawberry planting. Summary of the Invention

[0011] Preferably, a top rod is fixedly connected to the outer surface of the rear end of the swing arm, the end of the pull rod away from the top rod is rotatably connected to the top rod, a fixed sleeve is fixedly connected to the end of the swing arm away from the movable rod, a connecting tube is fixedly connected to the inner surface of the fixed sleeve, and an expansion tube is slidably connected to the outer surface of the connecting tube. The expansion tube is composed of two sets of symmetrically distributed semi-circular conical tubes.

[0012] Preferably, an expansion assembly is provided between the connecting pipe and the expansion pipe. The expansion assembly includes a guide groove formed on the outer surface of the connecting pipe, and a guide block is fixedly connected to the inner surface of the expansion pipe. The guide block is located inside the guide groove and slides in contact with the inner surface of the guide groove.

[0013] Preferably, the outer surface of the expansion tube is embedded with a slot, and the inner surface of the slot is engaged with a cable tie. Both the slot and the cable tie are annular.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. This solution uses baffles inside the distribution pipe to limit the strawberry seedlings, allowing them to stay outside the baffles under centrifugal force. The weight of the seedlings will be biased towards both sides of the distribution pipe. When the seedlings fall from the distribution pipe for transplanting, their branches will tilt towards the furrows on both sides, thus enabling directional control of the planting direction and improving the transplanting accuracy to a certain extent. 2. This solution uses a protective component and a flap to support the strawberry seedlings, storing them inside the connecting tube. The seedlings on the flap fall into the soil, effectively reducing damage to the roots of the strawberry seedlings during the movement of the expansion tube. It also reduces the probability of the roots of the strawberry seedlings rubbing against the soil during the cutting process, thus ensuring the integrity of the strawberry seedling roots and stems and further improving the survival rate of transplanted strawberry seedlings. 3. This solution, by setting up a discharge component, has several sets of trays that support and lift the roots and stems of the strawberry seedlings. This prevents damage to the roots and stems caused by friction between the strawberry seedlings and the surface of the fixed frame during the rotation of the rotating seat, thereby improving the survival rate of strawberry seedlings after transplanting to a certain extent.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1 to 7 This invention provides a technical solution: A transplanter for strawberry seedling cultivation includes a frame 11. A second motor 29 is fixedly connected to the lower outer surface of the frame 11. A rotating seat 18 is fixedly connected to the upper end of the output shaft of the second motor 29. A distributing pipe 19 is rotatably connected to the outer surface of the rotating seat 18. An orientation component is provided inside the distributing pipe 19. The orientation component includes a baffle 50 fixedly connected to the inner surface of the distributing pipe 19. A toothed ring 35 is fixedly connected to the outer surface of the distributing pipe 19. A fixing frame 16 is fixedly connected to the outer surface of the frame 11. A second toothed ring 36 is fixedly connected to the upper outer surface of the fixing frame 16. The first toothed ring 35 and the second toothed ring 36 are meshed and connected in a transmission manner. The lower outer surface of the distributing pipe 19 is in sliding contact with the upper surface of the fixing frame 16.

[0021] By adopting the above technical solution, when transplanting strawberry seedlings using a transplanter, the branches of the strawberry seedlings need to face the furrows on both sides. For this purpose, an orientation component is installed. During operation, motor 29 is started, and the frame 11 is fixedly supported by the fixing frame 16. The output shaft of motor 29 drives the rotating seat 18 to rotate, which in turn drives the distributing tube 19 to rotate in a circular motion. The operator places the strawberry seedlings one by one into the distributing tube 19. During the movement of the distributing tube 19, the toothed ring 36 on its surface moves synchronously. The toothed ring 36 is connected to the toothed ring 35 through meshing transmission and rotates synchronously during its circular motion. The toothed ring 36 drives the distributing tube 19 to rotate, and the strawberry seedlings inside the distributing tube 19 adhere to the tube under the action of centrifugal force. Inside the inner wall of the distribution pipe 19, the baffle 50 can limit the strawberry seedlings, allowing them to stay outside the baffle 50 under centrifugal force. By calculating the transmission coefficients of the toothed ring 35 and the toothed ring 36, and selecting the appropriate number of teeth for the toothed ring 35 and the toothed ring 36, when the rotating seat 18 drives the distribution pipe 19 to the far right, the distribution pipe 19 will simultaneously drive the baffle 50 to the left and right sides. At this time, the surface of the baffle 50 will be perpendicular to the moving direction of the frame 11. The weight of the strawberry seedlings will be biased towards the sides of the distribution pipe 19. When the strawberry seedlings fall from the inside of the distribution pipe 19 for transplanting, the branches of the strawberry seedlings will tilt towards the furrows on both sides, thereby achieving directional control of the planting direction of the strawberry seedlings and improving the transplanting accuracy of the strawberry seedlings to a certain extent.

[0022] Specifically, such as Figure 4 and Figure 6 As shown, the number of the distributing pipes 19 is several groups and they are arranged in a ring array. The inner side of the distributing pipe 19 is provided with a discharge assembly. The discharge assembly includes a support plate 37 fixedly connected to the inner surface of the distributing pipe 19. The support plate 37 has a fan-shaped structure and is made of elastic material. The number of the support plates 37 is several groups and they are arranged in a ring array. The upper end of the distributing pipe 19 is conical.

[0023] A traction bar 38 is fixedly connected to the lower outer surface of the support plate 37. An adjusting rod 39 is fixedly connected to the lower end of the traction bar 38. The adjusting rod 39 is in the shape of a ring. The lower side of the outer surface of the adjusting rod 39 slides in contact with the upper outer surface of the fixing frame 16. A through hole 15 is opened through the outer surface of the fixing frame 16. A guide tube 30 is fixedly connected to the lower outer surface of the fixing frame 16. The guide tube 30 is located directly below the through hole 15.

[0024] By adopting the above technical solution, in order to protect the roots and stems of strawberry seedlings and reduce damage to the roots and stems during transplanting, a discharge component is set up. The lower end of the adjusting rod 39 slides in contact with the upper side of the fixing frame 16. At this time, the trays 37 are gathered under their own elastic force. After a single strawberry seedling is put into the distributing pipe 19, several sets of trays 37 will support the roots and stems of the strawberry seedlings, thereby preventing damage to the roots and stems caused by friction between the strawberry seedlings and the surface of the fixing frame 16 during the movement of the rotating seat 18. This can improve the survival rate of strawberry seedlings after transplanting to a certain extent. When the distributing... When the tube 19 moves to the through hole 15, the adjusting rod 39 will disengage from the surface of the fixing frame 16. At this time, the adjusting rod 39 will slide down a distance and pull the tray 37 through the traction bar 38. Under the action of the pulling force, the tray 37 will expand outward from the gathered shape, so that the strawberry seedlings on its upper side will fall into the tube 30. As the rotating seat 18 drives the distributing tube 19 to continue to rotate, the adjusting rod 39 will contact the upper side of the rotating seat 18 and move upward again. The circular adjusting rod 39 can make each group of trays 37 flip upward and gather synchronously, thereby realizing the recycling and reset of the trays 37.

[0025] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, a drive assembly is provided on the outside of the frame 11. The drive assembly includes a mounting base 12 fixedly connected to the lower outer surface of the frame 11. A drive rod 13 is rotatably connected to the outer surface of the mounting base 12. A roller 14 is fixedly connected to the outer surface of the drive rod 13. A motor 28 is fixedly connected to the outer surface of the mounting base 12. The output shaft of the motor 28 is fixedly connected to the drive rod 13.

[0026] A mounting plate 23 is fixedly connected to the lower outer surface of the fixed frame 16. The mounting plate 23 has a U-shaped structure. A sprocket 20 is fixedly connected to the outer surface of the drive rod 13. A connecting shaft 24 is rotatably connected to the outer surface of the mounting plate 23. A sprocket 22 is fixedly connected to the outer surface of the connecting shaft 24. A chain 21 is rotatably connected to the outer surfaces of the sprocket 20 and the sprocket 22. A seat 17 is fixedly connected to the upper outer surface of the fixed frame 16.

[0027] By adopting the above technical solution, in order to improve the working efficiency of the transplanter, a drive component is set up. When working, motor 28 is started and running. Mounting base 12 provides fixed support for motor 28. Motor 28 is a dual-shaft motor. Motor 28 drives roller 14 to rotate through drive rod 13. Drive rod 13 provides fixed support for frame 11 through mounting base 12. The rotation of roller 14 drives frame 11 to move smoothly. Frame 11 provides fixed support for seat 17 through fixing frame 16. The operator sits on seat 17 and puts strawberry seedlings into the dispensing pipe 19. During the rotation of drive rod 13, it drives sprocket 20 to rotate synchronously. Sprocket 20 drives sprocket 22 to rotate synchronously through chain 21, thereby driving shaft 24 to rotate through sprocket 22.

[0028] Specifically, such as Figure 4 and Figure 7 As shown, the mounting plate 23 is provided with a cutting assembly on its inner side. The cutting assembly includes a cam 32 fixedly connected to the outer surface of the connecting shaft 24. A push rod 33 is fixedly connected to the outer surface of the cam 32. A pull rod 34 is rotatably connected to the outer surface of the push rod 33. A movable rod 25 is fixedly connected to the inner surface of the mounting plate 23. A swing arm 27 is rotatably connected to the outer surface of the movable rod 25.

[0029] A top rod 26 is fixedly connected to the outer surface of the rear end of the swing arm 27. The end of the pull rod 34 away from the top rod 33 is rotatably connected to the top rod 26. A fixed sleeve 40 is fixedly connected to the end of the swing arm 27 away from the movable rod 25. A connecting tube 41 is fixedly connected to the inner surface of the fixed sleeve 40. An expansion tube 43 is slidably connected to the outer surface of the connecting tube 41. The expansion tube 43 is composed of two sets of symmetrically distributed semi-circular conical tubes.

[0030] By adopting the above technical solution, the mounting plate 23 supports the rotation of the swing arm 27 via the movable rod 25, and the connecting shaft 24 drives the cam 32 to move synchronously. When the protrusion of the cam 32 rotates to the lower side, the cam 32 drives the pull rod 34 to swing via the push rod 23. The pull rod 34 drives the swing arm 27 to move downward via the push rod 1 26. Under the action of traction, the swing arm 27 will rotate around the movable rod 25 as the fulcrum. During the downward movement of the swing arm 27, the connecting rod will move downward synchronously via the fixed sleeve 40. The connecting pipe 41 drives the expansion pipe 43 to be inserted into the soil, and the strawberry seedlings are inserted into the soil through the expansion pipe 43. When the protrusion of the cam 32 rotates upward from the bottom, the cam 32 pulls the swing arm 27 upward through the pull rod 34. At this time, the swing arm 27 drives the connecting pipe 41 to move to the lower side of the guide tube 30 through the fixed sleeve 40, so that the strawberry seedlings inside the distribution pipe 19 are connected to the inside of the connecting pipe 41 through the guide tube 30, thereby realizing the continuous cutting operation of strawberry seedlings, which can improve the transplanting efficiency of strawberry seedlings to a certain extent.

[0031] Specifically, such as Figure 4 and Figure 6 As shown, an expansion assembly is provided between the connecting pipe 41 and the expansion pipe 43. The expansion assembly includes a guide groove 42 formed on the outer surface of the connecting pipe 41, and a guide block 44 is fixedly connected to the inner surface of the expansion pipe 43. The guide block 44 is located inside the guide groove 42 and slides in contact with the inner surface of the guide groove 42.

[0032] The expansion tube 43 has an embedded slot 45 on its outer surface, and a cable tie 46 is engaged with the inner surface of the slot 45. Both the slot 45 and the cable tie 46 are annular. The lower side of the outer surface of the connecting tube 41 slides in contact with the inner wall of the expansion tube 43, and the upper side of the connecting tube 41 is conical.

[0033] By adopting the above technical solution, the slot 45 can engage with the cable tie 46. The circular cable tie 46, bound to the outside of the expansion tube 43, not only allows for a certain degree of elastic deformation between the two sets of expansion tubes 43, but also, under the elastic force of the cable tie 46, keeps the expansion tube 43 in contact with the outer surface of the connecting tube 41. When the lower end of the expansion tube 43 is inserted into the soil a certain distance, it will stop moving due to the resistance of the soil. As the connecting tube 41 continues to move downwards, relative sliding will occur between the connecting tube 41 and the expansion tube 43. The guide groove 42, in conjunction with the guide block 44, can provide a certain degree of guidance for the expansion tube 43. The limiting function makes the expansion tube 43 slide more smoothly along the outside of the connecting tube 41. The lower side of the connecting tube 41 will slide in contact with the inner wall of the expansion tube 43. Since the lower side of the outer surface of the expansion tube 43 is conical, as the connecting tube 41 gradually moves down, the connecting tube 41 will push the expansion tube 43 outward. The movement of the expansion tube 43 can push the soil around the expansion tube 43 outward, so that the roots of the strawberry seedling can be completely buried in the soil, thus enabling the rapid cutting and transplanting of strawberry seedlings. After the cutting is completed, as the connecting tube 41 drives the expansion tube 43 to gradually move up, the expansion tube 43 will re-gather together under the elastic force of the tie 46.

[0034] Specifically, such as Figure 6 As shown, a protective assembly is provided inside the connecting pipe 41. The protective assembly includes a pin 49 fixedly connected to the inner surface of the connecting pipe 41. A rotating plate 48 is rotatably connected to the outer surface of the pin 49. An elastic band 47 is fixedly connected to the lower outer surface of the rotating plate 48. The lower end of the elastic band 47 is fixedly connected to the lower side of the inner surface of the guide groove 42. A flap 31 is fixedly connected to the outer surface of the rotating plate 48. The flap 31 is located inside the connecting pipe 41. The rotating plate 48 penetrates into the guide groove 42 and slides in contact with the upper surface of the guide block 44.

[0035] By adopting the above technical solution, in order to reduce the squeezing damage to the strawberry seedling roots during the gathering process of the expansion tube 43, a protective component is set up. After the strawberry seedling enters the connecting tube 41, it will fall on the upper surface of the flip plate 31. The flip plate 31 supports the strawberry seedling, thus storing the strawberry seedling inside the connecting tube 41. When the guide block 44 slides upward inside the guide groove 42, the upper end of the guide block 44 will contact the lower surface of the rotating plate 48. At this time, the guide block 44 will push the rotating plate 48, causing the rotating plate 48 to rotate around the pin 49 as the fulcrum. At this time, the rotating plate 48 will drive the flip plate 31 to flip downward. At this time, the expansion tube 43 will be in an expanded state, and the strawberry seedling on the surface of the flip plate 31 will fall into the soil. This can effectively reduce the damage to the strawberry seedling roots during the movement of the expansion tube 43, and also reduce the probability of the strawberry seedling roots coming into friction contact with the soil during the cutting process. This can effectively ensure the integrity of the strawberry seedling roots and stems, and further improve the survival rate of transplanted strawberry seedlings.

[0036] Working principle: The operator sits on seat 17 and places strawberry seedlings into the dispensing tube 19. The rotation of roller 14 drives the frame 11 to move smoothly. During this movement, the dispensing tube 19 drives the toothed ring 36 on its surface to rotate synchronously. The toothed ring 36 then rotates the dispensing tube 19. Under centrifugal force, the strawberry seedlings inside the dispensing tube 19 adhere to its inner wall. When the strawberry seedlings fall from the dispensing tube 19 for transplanting, the strawberry seedlings... The branches will lean towards the furrows on both sides, and several sets of support plates 37 will support the roots and stems of the strawberry seedlings. When the feed pipe 19 moves to the through hole 15, the adjusting rod 39 will disengage from the surface of the fixing frame 16, and the support plates 37 will expand outward from a gathered shape under the pull, causing the strawberry seedlings on their upper side to fall into the guide tube 30. The first sprocket 20 drives the second sprocket 22 to rotate synchronously through the chain 21, thereby driving the connecting shaft 24 to rotate through the second sprocket 22. 7. During the downward movement, the connecting tube 41 moves downward synchronously through the fixed sleeve 40. The connecting tube 41 drives the expansion tube 43 to be inserted into the soil. The expansion tube 43 opens to insert the strawberry seedling into the soil. As the connecting tube 41 gradually moves downward, it will push the expansion tube 43 outward. The movement of the expansion tube 43 can push the soil around the expansion tube 43 outward, so that the roots of the strawberry seedling can be completely buried in the soil. When the guide block 44 slides upward inside the guide groove 42, the guide block 44 will push the rotating plate 48. The rotating plate 48 will drive the flip plate 31 to flip downward. At this time, the expansion tube 43 will be in an expanded state, and the strawberry seedling on the surface of the flip plate 31 will fall into the soil, which can effectively reduce the damage to the roots of the strawberry seedling during the movement of the expansion tube 43. After the strawberry seedling slides off the surface of the flip plate 31, the flip plate 31 and the rotating plate 48 will move in the opposite direction and reset under the elastic force of the elastic band 47.
