Description

Technical Field

[0001] This utility model relates to the field of tobacco seedling transplanting technology, specifically to a multifunctional tobacco seedling transplanter. Background Technology

[0002] Transplanting tobacco seedlings onto plastic film is a common cultivation method in tobacco planting. Traditionally, transplanting is mainly done manually, requiring manual drilling, transplanting, and watering, which is labor-intensive and inefficient. While existing transplanting machines can perform basic transplanting functions and reduce labor to some extent, the coordination between drilling and transplanting actions is poor, affecting transplanting quality. Furthermore, their functions are relatively limited, and manual watering is still required after transplanting. Therefore, existing transplanting machines still need further improvement. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a multifunctional tobacco seedling transplanter that can perform hole drilling, transplanting, and watering in one operation, reducing the workload of personnel, making it more convenient to use, and enhancing the coordination of operations during the transplanting process, thereby improving the transplanting quality.

[0004] This utility model is achieved through the following technical solution: a multifunctional tobacco seedling transplanter, including a frame, a transplanting mechanism and a punching mechanism mounted on the frame. The transplanting mechanism includes a first disc, multiple transplanting cups, and a lifting ring. The first disc is rotatably mounted on the top of the frame, with its center line vertically positioned. The multiple transplanting cups are evenly distributed around the circumference of the first disc. The transplanting cups are fixed to the outer wall of the first disc via connecting rods. The top and bottom of the transplanting cups are open, and a cup lid is hinged to the bottom of the transplanting cup. The lifting ring is located below the transplanting cup and fixed to the frame, with its upper end face contacting the cup lid at the bottom of the transplanting cup. The bottom opening of the transplanting cup, which is sealed by the cup lid, is touched, and a seedling dropping opening is provided on the lifting ring; the perforation mechanism includes a vertically extending seedling guide tube, which is located at the bottom of the frame and slides up and down. The upper end of the seedling guide tube is opposite to the seedling dropping opening, and the lower end of the seedling guide tube is provided with a perforating duckbill assembly; a drive motor is also fixedly installed at the bottom of the frame, and an output long shaft is fixedly connected to the output long shaft. A second disc is fixedly connected to the output long shaft. The center line of the second disc is set horizontally, and a transmission rod is provided on the second disc. One end of the transmission rod is hinged to the side away from the center of the second disc, and the other end of the transmission rod is hinged to the seedling guide tube.

[0005] In operation, this system uses a drive motor to rotate the output shaft, which in turn rotates the second disc. This causes the hinged transmission rod to oscillate in a curved path, which in turn moves the seedling guide tube up and down. When the guide tube moves downward, it inserts into the soil through the perforating duckbill assembly to perform the perforation operation. Simultaneously, the rotation of the first disc causes the transplanting cup to move circumferentially. When it passes the seedling drop opening, the cup lid at the bottom of the transplanting cup loses the support of the lifting ring and automatically opens, allowing the tobacco seedling to fall into the guide tube. The seedling then falls along the guide tube into the soil through the opening, thus completing the transplanting operation.

[0006] As an optimization, a driving bevel gear is fixedly connected to the output long shaft, and a rotating shaft is fixedly connected to the bottom of the first disk. The lower end of the rotating shaft passes through the top of the frame and is fixedly connected to a driven bevel gear, which meshes with the driving bevel gear. In this optimized design, the rotation of the output long shaft can drive the first disk to rotate, allowing drilling and transplanting operations to be performed simultaneously, resulting in better coordination. Furthermore, by driving both operations with a single drive motor, energy is saved and costs are reduced.

[0007] As an optimization, a seedling receiving hopper is fixedly connected to the top of the frame. The seedling receiving hopper is located between the seedling dropping opening and the seedling guide tube, with the upper end of the hopper below the seedling dropping opening and the lower end inserted into the upper port of the seedling guide tube. This optimized solution further guides the tobacco seedlings smoothly into the seedling guide tube through the seedling receiving hopper, preventing the seedlings from falling outside the seedling guide tube.

[0008] As an optimization, one end of the supporting ring is bent downwards to form a transition slope. In this optimized design, the lid of the transplanting cup can move along the transition slope, allowing the lid to close smoothly and thus sealing the opening at the bottom of the transplanting cup.

[0009] As an optimization, a horizontal fixing rod is fixedly connected to the outer wall of the seedling guide tube. Vertical guide rods pass through both ends of the horizontal fixing rod, and the horizontal fixing rod and guide rods are slidably connected. The upper end of the guide rod is fixedly connected to the top of the frame. This optimized design improves the sliding stability of the seedling guide tube by allowing it to slide up and down along the guide rods.

[0010] As an optimization, the perforating nozzle assembly includes a first nozzle and a second nozzle facing each other, and a actuator. The tops of the first nozzle and the second nozzle, located away from each other, are hinged to the lower end of the seedling guide tube. A seedling storage chamber communicating with the inner cavity of the seedling guide tube is formed between the first nozzle and the second nozzle. The actuator drives the opening and closing of the first nozzle and the second nozzle. In this optimized design, when the first nozzle and the second nozzle are closed, they are pointed, making it easy to insert into the soil. The actuator drives the first nozzle and the second nozzle to open, thus forming an opening for easy insertion of tobacco seedlings.

[0011] As an optimization, the actuating component includes a vertically arranged top rod with a pressure plate fixedly connected to its bottom. Two fixing blocks are slidably sleeved on the top rod, and the two fixing blocks are distributed vertically and fixedly connected to the outer wall of the seedling guide tube. A transverse connecting rod is fixedly connected to the top rod, and the transverse connecting rod is located between the two fixing blocks. A return spring is provided between the transverse connecting rod and the fixing block located at the top. Sub-connecting rods are hinged to both ends of the transverse connecting rod, and the ends of the two sub-connecting rods away from the transverse connecting rod are respectively hinged to the first duckbill and the second duckbill.

[0012] In this optimized design, when the first and second duckbill prongs are inserted into the soil in the closed state, the pressure plate at the bottom of the push rod presses against the soil surface. As the first and second duckbill prongs continue to penetrate deeper into the soil, the push rod slides upward, thereby driving the horizontal connecting rod upward. This, in turn, pulls the first and second duckbill prongs outward relative to each other through the auxiliary connecting rods at both ends, thus opening the first and second duckbill prongs. After transplanting, the seedling guide tube rises, and the pressure plate, no longer in contact with the soil, loses its support. The return spring pushes the horizontal connecting rod downward to reset, thus closing the first and second duckbill prongs for future use.

[0013] As an optimization, a water tank is fixedly installed on the top of the frame, and a water supply pipe is fixedly connected to the bottom of the water tank. A control valve is installed on the water supply pipe, and the outlet of the water supply pipe extends above the perforated duckbill assembly. In this optimized solution, after the transplanting operation is completed, the seedling guide pipe moves the perforated duckbill assembly upward out of the soil, and the water in the water tank is output outward through the control valve. Since the outlet of the water supply pipe is located above the perforated duckbill assembly, when the perforated duckbill assembly is moved out of the soil, the output water can just fall near the soil opening, thereby nourishing the tobacco seedlings in the opening.

[0014] As an optimization, a stirring motor is fixedly installed on the top of the water tank, and a stirring shaft is fixedly connected to the output end of the stirring motor. The stirring shaft extends downward into the water tank, and multiple stirring rods are evenly distributed on the outer wall of the stirring shaft. This optimized solution drives the stirring shaft to rotate through the stirring motor, thereby causing the stirring rods to stir the materials in the water tank and mix them evenly.

[0015] As an optimization, a seedling box is fixed to the top of the frame. This optimized solution places the seedling box on the frame, making it convenient to transfer the tobacco seedlings cultivated in the seedling box into the transplanting cups at any time.

[0016] The beneficial effects of this invention are as follows: By driving the output long shaft to rotate via a drive motor, the first and second discs can rotate simultaneously, thus enabling simultaneous drilling and transplanting operations with enhanced coordination. During drilling, when the first and second beaks are closed and inserted into the soil, a toggle mechanism automatically opens them outwards; when they are removed from the soil, they automatically close again, making it more convenient to use. After transplanting, water from the water tank is injected into the soil near the opening via a control valve to nourish the tobacco seedlings, eliminating the need for subsequent watering and reducing labor. This integrated system of drilling, transplanting, and watering makes it even more convenient to use. Attached Figure Description

[0027] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0028] like Figures 1-8 As shown, a multi-functional tobacco seedling transplanter includes a frame 1, with ground wheels 20 mounted on the frame 1, and a transplanting mechanism and a punching mechanism provided on the frame 1.

[0029] The transplanting mechanism includes a first disc 15, multiple transplanting cups 13, and a lifting ring 17. The first disc 15 is rotatably mounted on the top of the frame 1, and its center line is vertically aligned. In this embodiment, a rotating shaft 16 is fixedly connected to the bottom center of the first disc 15. The rotating shaft 16 extends vertically and is rotatably connected to the top of the frame 1, thereby enabling the rotating installation of the first disc 15.

[0030] Multiple transplanting cups 13 are evenly distributed around the circumference of the first disc 15. The transplanting cups 13 are fixed to the outer wall of the first disc 15 via connecting rods 21. The top and bottom of the transplanting cups 13 are open, and a cup lid 36 is hinged to the bottom of the transplanting cups 13. In this embodiment, 10 transplanting cups 13 are evenly distributed around the circumference of the first disc 15. The tobacco seedlings can be placed into the transplanting cups 13 through the top opening of the transplanting cups 13.

[0031] The lifting ring 17 is located below the transplanting cup 13 and is fixedly connected to the frame 1. The upper end face of the lifting ring 17 contacts the cup cover 36 at the bottom of the transplanting cup 13 and the cup cover 36 seals the bottom opening of the transplanting cup 13. The lifting ring 17 has a seedling drop opening 25.

[0032] The lifting ring 17 described in this embodiment is a circular ring structure. The lifting ring 17 and the rotating shaft 16 are coaxially arranged. The distance from the center of the transplanting cup 13 to the rotating shaft 16 is the same as the radius of the lifting ring 17, so that the lifting ring 17 can be supported on the bottom of the transplanting cup 13. The bottom of the lifting ring 17 is fixed to the top of the frame 1 through a support rod.

[0033] When the first disc 15 rotates, it drives multiple transplanting cups 13 to rotate. When the transplanting cup 13 passes the seedling drop opening 25, the cup lid 36 at the bottom of the transplanting cup 13 loses the support of the lifting ring 17 and opens automatically, causing the tobacco seedlings in the transplanting cup 13 to fall out.

[0034] Preferably, one end of the lifting ring 17 is bent downward to form a transition slope 22. After the transplanting cup 13 passes the seedling inlet 25, the cup lid 36 can move along the transition slope 22 to close the cup lid 36 smoothly, thereby sealing the bottom opening of the transplanting cup 13.

[0035] The perforating mechanism includes a vertically extending seedling guide tube 5, which is located at the bottom of the frame 1 and slides up and down. The upper end of the seedling guide tube 5 is opposite to the seedling dropping opening 25, and the lower end of the seedling guide tube 5 is equipped with a perforating nozzle assembly. Because the seedling guide tube 5 and the seedling dropping opening 25 are opposite each other, when tobacco seedlings fall out of the transplanting cup 13, they will fall into the seedling guide tube 5. The perforating nozzle assembly is used to perforate the soil. When the seedling guide tube 5 slides downwards, the perforating nozzle assembly can be inserted into the soil to create a hole, allowing the tobacco seedlings in the seedling guide tube 5 to be transplanted into the hole. After completion, the seedling guide tube 5 slides upwards, removing the perforating nozzle assembly from the soil to prepare for the next perforation operation.

[0036] Specifically, in this embodiment, a horizontal fixing rod 26 is fixedly connected to the outer wall of the seedling guide tube 5. In this embodiment, the horizontal fixing rod 26 is fixedly connected to the side of the seedling guide tube 5 near the rotating shaft 16. Vertical guide rods 7 are passed through both ends of the horizontal fixing rod 26, and the horizontal fixing rod 26 is slidably connected to the guide rods 7. The upper end of the guide rod 7 is fixedly connected to the top of the frame 1. The seedling guide tube 5 improves sliding stability by sliding up and down along the guide rods 7.

[0037] Since the seedling inlet 25 and the seedling guide tube 5 are located above and below the top of the frame 1 respectively, and there is a certain distance between them, to prevent the tobacco seedlings from falling outside the seedling guide tube 5 when discharged, a seedling receiving hopper 12 is fixedly connected to the top of the frame 1 in this embodiment. The seedling receiving hopper 12 is located between the seedling inlet 25 and the seedling guide tube 5, with the upper end of the seedling receiving hopper 12 located below the seedling inlet 25 and the lower end of the seedling receiving hopper 12 inserted into the upper port of the seedling guide tube 5. Through the transitional guidance of the seedling receiving hopper 12, the tobacco seedlings can fall smoothly into the seedling guide tube 5.

[0038] To enable the rotation of the first disc 15 and the up-and-down sliding of the seedling guide tube 5, a drive motor 19 is also fixedly installed at the bottom of the frame 1, and an output long shaft 3 is fixedly connected to the output end of the drive motor 19. In this embodiment, the seedling guide tube 5 is located in front of the rotating shaft 16, so the output long shaft 3 also extends in the front-to-back direction.

[0039] A drive bevel gear 18 is fixedly connected to the output long shaft 3, and the lower end of the rotating shaft 16 passes through the top of the frame 1 and is fixedly connected to a driven bevel gear 2. The driven bevel gear 2 and the drive bevel gear 18 mesh with each other.

[0040] A second disk 4 is fixedly connected to the output long shaft 3. The second disk 4 is located on the side of the drive bevel gear 18 away from the drive motor 19. The center line of the second disk 4 is horizontally set. A transmission rod 35 is provided on the second disk 4. One end of the transmission rod 35 is hinged to the side away from the center of the second disk 4, and the other end of the transmission rod 35 is hinged to the seedling guide tube 5. In this embodiment, the other end of the transmission rod 35 is hinged to a horizontal fixing rod 26 fixedly connected to the seedling guide tube 5.

[0041] The output long shaft 3 is driven to rotate by the drive motor 19, which in turn drives the rotating shaft 16 to rotate, thereby causing the first disc 15 to rotate, which in turn causes multiple transplanting cups 13 to rotate for transplanting. Simultaneously, the rotation of the output long shaft 3 drives the second disc 4 to rotate, causing the hinged transmission rod 35 to oscillate in a curved path, which in turn drives the guide tube 5 to move up and down for punching operations. The punching and transplanting operations are performed simultaneously, resulting in better coordination. Furthermore, driving both operations with a single drive motor 19 saves energy and reduces costs.

[0042] Specifically, the perforated duckbill assembly includes a first duckbill 31 and a second duckbill 29 facing each other, and a toggle member. The tops of the first duckbill 31 and the tops of the second duckbill 29 are hinged to the lower end of the seedling guide tube 5 at opposite ends. A seedling storage cavity communicating with the inner cavity of the seedling guide tube 5 is formed between the first duckbill 31 and the second duckbill 29. The toggle member drives the opening and closing of the first duckbill 31 and the second duckbill 29.

[0043] When the first beak 31 and the second beak 29 are closed, the perforation beak assembly is in its initial state, and the tobacco seedlings in the seedling guide tube 5 will fall into the seedling storage chamber. When closed, the first beak 31 and the second beak 29 are pointed, making them easy to insert into the soil. After insertion into the soil, the first beak 31 and the second beak 29 can be opened by a toggle mechanism to form an opening, into which the tobacco seedlings in the seedling storage chamber can fall.

[0044] Specifically, the actuating component includes a vertically arranged top rod 27, with a pressure plate 30 fixedly connected to the bottom of the top rod 27. Two fixing blocks 28 are slidably sleeved on the top rod 27, and the two fixing blocks 28 are distributed vertically and fixedly connected to the outer wall of the seedling guide tube 5. A transverse connecting rod 33 is fixedly connected to the top rod 27, and the transverse connecting rod 33 is located between the two fixing blocks 28. A return spring 34 is provided between the transverse connecting rod 33 and the fixing block 28 located at the top. Both ends of the transverse connecting rod 33 are hinged to auxiliary connecting rods 32, and the ends of the two auxiliary connecting rods 32 away from the transverse connecting rod 33 are respectively hinged to the first duckbill 31 and the second duckbill 29.

[0045] In this embodiment, the actuating component is located on the front side of the seedling guide tube 5, and the return spring 34 is sleeved on the top rod 27. When the first duckbill 31 and the second duckbill 29 are closed, there is a distance of 5-7 cm between the bottom of the pressure plate 30 and the lower ends of the first duckbill 31 and the second duckbill 29. Thus, when the seedling guide tube 5 slides downward, the first duckbill 31 and the second duckbill 29 will be inserted into the soil in a closed state. After they have been inserted 5-7 cm, the pressure plate 30 will press against the surface of the soil to meet the drilling depth. As the first duckbill 31 and the second duckbill 29 continue to penetrate deeper into the soil, the pressure plate 30, supported by the soil, will push the top rod 27 to slide upward, thereby driving the horizontal connecting rod 33 to move upward. This, in turn, pulls the first duckbill 31 and the second duckbill 29 outward through the auxiliary connecting rods 32 at both ends, thereby driving the first duckbill 31 and the second duckbill 29 to open, thus expanding the opening and allowing the tobacco seedling to fall into the opening. After transplanting, the seedling guide tube 5 slides upward, causing the first duckbill 31 and the second duckbill 29 to leave the soil and open the hole. At this time, the pressure plate 30 is no longer in contact with the soil and loses its support. The return spring 34 pushes the horizontal connecting rod 33 to move downward and reset, thereby resetting and closing the first duckbill 31 and the second duckbill 29, making it convenient for the next hole drilling.

[0046] A water tank 11 is fixedly mounted on the top of the frame 1, and a water supply pipe 6 is fixedly connected to the bottom of the water tank 11. A control valve 8 is installed on the water supply pipe 6, and the outlet of the water supply pipe 6 extends above the perforated duckbill assembly. In this embodiment, both the water supply pipe 6 and the control valve 8 are fixedly connected to the bottom of the frame 1. Water in the water tank 11 is output through the control valve 8. Since the outlet of the water supply pipe 6 is located above the perforated duckbill assembly, when the perforated duckbill assembly leaves the soil, the output water falls precisely near the opening in the soil, thereby achieving the watering operation for the tobacco seedlings.

[0047] When in use, a switch button for controlling the operation of the control valve 8 can be installed on the frame 1. Personnel can use the switch button to make the control valve 8 perform the pumping and draining action, or the controller can control the control valve 8 to pump and drain once every certain period of time, as long as it can meet the watering operation. The above method is the existing conventional technology, and will not be elaborated on here.

[0048] Preferably, a stirring motor 10 is fixedly mounted on the top of the water tank 11, and a stirring shaft 23 is fixedly connected to the output end of the stirring motor 10. The stirring shaft 23 extends downward into the water tank 11, and multiple stirring rods 9 are evenly distributed on the outer wall of the stirring shaft 23. In use, nutrient solution can be added to the water tank 11, and the stirring motor 10 drives the stirring shaft 23 to rotate, thereby causing the stirring rods 9 to stir and mix the nutrient solution and water evenly.

[0049] A seedling box 14 is fixedly mounted on the top of the frame 1. The seedling box 14 is located above the first disc 15 and between multiple transplanting cups 13. The seedling box 14 is fixedly connected to the top of the frame 1 via a support frame 24. The tobacco seedlings cultivated in the seedling box 14 are stored in the seedling box 14. In use, personnel can place the tobacco seedlings cultivated in the seedling box 14 into the transplanting cups 13 for transplanting.

[0050] Working principle: Personnel place the tobacco seedlings cultivated in the seedling box 14 into the transplanting cup 13. The drive motor 19 drives the output long shaft 3 to rotate, which in turn causes the first disc 15 to rotate, driving the transplanting cup 13 to rotate. When the transplanting cup 13 passes the seedling drop opening 25, the cup lid 36 at the bottom of the transplanting cup 13 opens, allowing the tobacco seedlings to fall through the seedling receiving hopper 12 into the seedling guide tube 5, and then into the seedling storage cavity formed when the first duckbill 31 and the second duckbill 29 are closed. The rotation of the output shaft 3 simultaneously drives the second disc 4 to rotate, which in turn causes the seedling guide tube 5 to slide downwards, allowing the first and second beaks 31 and 29, which were in a closed state, to be inserted into the soil. When they have been inserted 5-7 cm, the pressure plate 30 of the actuating element presses against the surface of the soil. As the first and second beaks 31 and 29 continue to penetrate deeper into the soil, the pressure plate 30, supported by the soil, pushes the top rod 27 upwards, thereby pulling the first and second beaks 31 and 29 outwards to complete the drilling. At this time, the tobacco seedlings in the storage chamber also fall into the opening, completing the transplanting. After the transplanting is completed, the first disc 15 continues to rotate, causing the seedling guide tube 5 to slide upwards again, causing the first and second beaks 31 and 29 to leave the soil opening. At this time, the pressure plate 30 is no longer in contact with the soil and loses its support. Under the push of the return spring 34, the first and second beaks 31 and 29 return to their closed positions, making it convenient for the next drilling. At the same time, after the transplanting is completed, the personnel control valve 8 to pump water and water the soil through the holes, realizing a multi-functional operation of drilling, transplanting and watering, which is more convenient to use.

[0051] Of course, the above description is not limited to the examples above. Technical features of this utility model not described can be implemented by or using existing technology, and will not be repeated here.
