Description

Technical Field

[0001] This utility model relates to the technical field of transplanters, and more particularly to a small transplanter. Background Technology

[0002] In the process of modern agricultural mechanization, transplanters are becoming increasingly important as key equipment for improving the efficiency and precision of crop planting.

[0003] Traditional transplanters often rely on multiple independent drive units to control various aspects of their operation, such as movement, seedling placement, and planting. While this design achieves some degree of modularity, it also presents several drawbacks. First, the coordinated operation of multiple drive units requires a complex control system for synchronization, increasing production costs and maintenance complexity. Second, slight response delays or errors between drive units can affect the overall accuracy of the transplanting operation, especially at high speeds or in complex terrain. Finally, the simultaneous operation of multiple drive units consumes a significant amount of energy, increasing operating costs and hindering energy conservation and environmental protection. Utility Model Content

[0005] Therefore, the purpose of this utility model is to propose a small transplanter. This device drives multiple actuators, such as seedling cup assembly, power wheel and duckbill mouth opener, through a main drive system, which simplifies the mechanical structure, effectively reduces production costs, and significantly improves control accuracy and operating efficiency. At the same time, by optimizing power distribution and energy management strategies, the system can achieve more efficient use of energy during operation, thereby reducing unnecessary energy consumption and conforming to the development trend of energy conservation and environmental protection.

[0006] To achieve the above objectives, this utility model proposes a small transplanter, comprising a body, a seedling cup assembly, a single-drive multi-linkage mechanism, a drive wheel, a duckbill mouth opener, and a pressing wheel.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Simplified mechanical structure: Traditional transplanters may require multiple independent motors or hydraulic cylinders to drive different components, which not only increases the complexity of the mechanical structure but also makes it difficult to control the weight and size of the whole machine. However, by using a single main drive system to transmit power to each actuator, the mechanical structure can be greatly simplified, making the transplanter more compact and lightweight.

[0017] 2. Reduced production costs: Due to the simplified mechanical structure, the number of required parts is reduced, and the processing and assembly costs are also reduced. At the same time, since the main drive system can be procured and maintained in a unified manner, the types of spare parts and inventory costs are reduced. In addition, the simplified structure also helps to improve the automation level of the production line, further reducing production costs.

[0018] 3. Improved control precision: A single main drive system means that the movement of all actuators is driven by the same power source, which makes it easier to achieve synchronization and coordination between the components. Through precise transmission ratio design and advanced control algorithms, it can ensure the accurate placement of seedling cups, the stable movement of the drive wheels, the accurate insertion of the duckbill mouth opener, and the accurate opening and closing of the duckbill mouth opener, thereby improving the precision and consistency of transplanting operations.

[0019] 4. Improved work efficiency: Due to the smoother coordination between various actuators, the small transplanter can maintain a high degree of continuity and stability during operation. In addition, the efficient transmission of the main drive system also ensures efficient use of power and reduces energy waste. Therefore, in the same working time, a small transplanter using a main drive system can complete more transplanting tasks, thus improving work efficiency.

[0020] 5. Energy saving and environmental protection: By optimizing power distribution and energy management strategies, the system can achieve more efficient use of energy during operation, thereby reducing unnecessary energy consumption, which is in line with the development trend of energy saving and environmental protection.

[0037] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0038] A small transplanter according to an embodiment of the present invention will now be described with reference to the accompanying drawings.

[0039] like Figures 1-7As shown, a small transplanter according to an embodiment of the present invention includes a body 1, a seedling cup assembly 2, a single-drive multi-linkage mechanism 3, a power wheel 4, a duckbill mouth opener 5, and a pressing wheel 11. The seedling cup assembly 2, the single-drive multi-linkage mechanism 3, and the power wheel 4 are sequentially arranged on the body 1 along the Z-axis. The duckbill mouth opener 5 is arranged on the single-drive multi-linkage mechanism 3 and corresponds to the position of the seedling cup assembly 2. The single-drive multi-linkage mechanism 3 is connected to the seedling cup assembly 2, the power wheel 4, and the duckbill mouth opener 5 respectively. The pressing wheel 11 is arranged on the body 1 and corresponds to the position of the duckbill mouth opener 5.

[0040] Specifically, the single-drive multi-linkage mechanism 3 synchronously triggers the operation of the seedling cup assembly 2, the power wheel 4, and the duckbill mouth opener 5. The operation of the seedling cup assembly 2 realizes the automatic seedling placement operation, the operation of the power wheel 4 drives the body 1 to move, and the operation of the duckbill mouth opener 5 realizes the seedling planting operation. The pressing wheel 11 is used to compact the soil around the seedling after planting to prevent the seedling from loosening. This device drives multiple actuators, such as the seedling cup assembly 2, the power wheel 4, and the duckbill mouth opener 5, through a main drive system, which simplifies the mechanical structure, effectively reduces production costs, and significantly improves control accuracy and operating efficiency. At the same time, by optimizing the power distribution and energy management strategy, the system can achieve more efficient use of energy during operation, thereby reducing unnecessary energy consumption, which is in line with the development trend of energy conservation and environmental protection.

[0041] In one embodiment of this utility model, such as Figure 2As shown, the seedling cup assembly 2 includes a straight seedling cup assembly 20, which includes a straight cup holder 21, a rotating shaft 22, a first transmission chain 23, a first transmission chain 24, a conical seedling cup 25, a sleeve 26, an upper protruding side block 27, and a lower protruding side block 28. The straight cup holder 21 is symmetrically bolted to the top of the machine body 1. The rotating shaft 22 is symmetrically rotatably connected to the inner wall of the straight cup holder 21. One end of each of the two sets of rotating shafts 22 passes through the top of the straight cup holder 21 and is fixedly connected to the first transmission chain 23. The two sets of first transmission chain 23 are connected by the first transmission chain 24. The conical seedling cups 25 are evenly fixed to the surface of the first transmission chain 24. The other ends of each of the two sets of rotating shafts 22 pass through the straight cup holder 21. 1. The bottom of the device is aligned with one end of the single-drive multi-linkage mechanism 3 and the position of the duckbill opening device 5. One end of the rotating shaft 22, which corresponds to one end of the single-drive multi-linkage mechanism 3, is connected to the single-drive multi-linkage mechanism 3. A sleeve 26 is fixedly connected to one end of the rotating shaft 22, which corresponds to the position of the duckbill opening device 5. The upper protruding side block 27 and the lower protruding side block 28 are respectively set on the outer surface of the sleeve 26. The upper protruding side block 27 and the lower protruding side block 28 are respectively aligned with the screw position set on the surface of the conical seedling cup 25. When the screw contacts the upper protruding side block 27 and the lower protruding side block 28, the conical seedling cup 25 will be triggered to open synchronously. When the screw separates from the upper protruding side block 27 and the lower protruding side block 28, the conical seedling cup 25 will automatically close under the action of the external circular spring.

[0042] It should be noted that the conical seedling cup 25 described in this embodiment is existing technology.

[0043] Specifically, the structure and connection relationship of the straight seedling cup assembly 20 are further explained. In use, the single-drive multi-linkage mechanism 3 drives the rotating shaft 22 to rotate synchronously. The rotation of the rotating shaft 22 drives multiple sets of conical seedling cups 25 to move synchronously through the cooperation of the first transmission chain 23 and the first transmission chain 24. When the screw on the conical seedling cup 25 contacts the upper protruding side block 27 and the lower protruding side block 28, the conical seedling cup 25 will be triggered to open synchronously. After the conical seedling cup 25 is opened, the seedlings inside fall into the duckbill opening device 5 under the action of gravity. When the screw separates from the upper protruding side block 27 and the lower protruding side block 28, the conical seedling cup 25 automatically closes under the action of the external circular spring.

[0044] In one embodiment of this utility model, such as Figure 3As shown, the single-drive multi-linkage mechanism 3 includes a frame 31, an internal drive transmission mechanism 32, an external drive transmission mechanism 33, and a return spring 34. The frame 31 is fixedly connected to the surface of the machine body 1. The internal drive transmission mechanism 32 is disposed on the inner wall of the frame 31. The external drive transmission mechanism 33 is symmetrically disposed on the outer surface of the frame 31. The external drive transmission mechanism 33 is connected to the rotating shaft 22 and the internal drive transmission mechanism 32 respectively. The duckbill mouth opener 5 is fixedly connected to the surface of the external drive transmission mechanism 33. One end of the return spring 34 is connected to the duckbill mouth opener 5, and the other end of the return spring 34 is connected to the surface of the frame 31.

[0045] Specifically, the structure and connection relationship of the single-drive multi-linkage mechanism 3 will be further explained. The operation of the internal drive transmission mechanism 32 synchronously drives the two sets of rotating shafts 22. At the same time, the operation of the internal drive transmission mechanism 32 also synchronously drives the two sets of external drive transmission mechanisms 33. The operation of the external drive transmission mechanism 33, in cooperation with the reset spring 34, synchronously drives the duckbill opening device 5 to achieve the seedling planting operation.

[0046] In one embodiment of this utility model, such as Figure 3 As shown, the internal drive transmission mechanism 32 includes a first rotating shaft 321, a second rotating shaft 322, a gear 323 of the same diameter, a reducer 324, a diesel engine 325, a synchronous gear 326, and a synchronous belt 327. The first rotating shaft 321 and the second rotating shaft 322 are rotatably connected to the inner wall of the frame 31 and are positioned correspondingly. The gear 323 of the same diameter is fixedly connected to the surfaces of the first rotating shaft 321 and the second rotating shaft 322, respectively, and meshes with each other. The reducer 324 is fixedly connected to the surface of the machine body 1 and is located at the bottom of the first rotating shaft 321. On the side, the diesel engine 325 is fixedly connected to the surface of the body 1 and connected to the reducer 324. The reducer 324 is provided with two sets of output ends. The power wheel 4 is fixedly connected to the surface of the output shaft at the lower end of the reducer 324. The synchronous gears 326 are fixedly connected to the surface of the output shaft at the upper end of the reducer 324 at the corresponding positions of the surface of the first rotating shaft 321 and are connected by the synchronous toothed belt 327. The two ends of the first rotating shaft 321 and the second rotating shaft 322 respectively pass through the outside of the frame 31 and are connected to the external drive transmission mechanism 33.

[0047] Specifically, the structure and connection relationship of the internal drive transmission mechanism 32 are further explained. When in use, the diesel engine 325 is started. The operation of the diesel engine 325 synchronously drives the reducer 324 to run. The output shaft located at the lower end of the reducer 324 rotates synchronously, driving the power wheel 4 to rotate. The rotation of the power wheel 4 synchronously drives the body 1 to move. The rotation of the output shaft located at the upper end of the reducer 324 is driven synchronously by the cooperation of the synchronous gear 326 and the synchronous belt 327, which in turn drives the first rotating shaft 321 to rotate. The first rotating shaft 321 synchronously drives the second rotating shaft 322 to rotate through the same diameter gear 323.

[0048] In one embodiment of this utility model, such as Figure 4 As shown, the external drive transmission mechanism 33 includes a movable rod 331, an irregularly shaped eccentric wheel 332, a travel limit screw 333, a crossbeam 334, a roller 335, a movable pressure rod 336, a right-angle converter 337, and a pull cable 338. The movable rod 331, irregularly shaped eccentric wheel 332, travel limit screw 333, and crossbeam 334 are sequentially arranged along the Z-axis on the outer surface of the frame 31. The roller 335 is fixedly connected to the surface of the movable rod 331 and contacts the surface of the irregularly shaped eccentric wheel 332. The movable pressure rod 336 is slidably connected to the outer surface of the travel limit screw 333, with one end of the movable pressure rod 336 connected to the irregularly shaped eccentric wheel 334. 2. The surface is hinged and fixed. The other end of the movable pressure rod 336 is hinged and fixed to the surface of the crossbeam 334. The duckbill mouth opener 5 is fixedly connected to the end surface of the crossbeam 334 away from the surface of the frame 31 and corresponds to the position of the sleeve 26. The right angle converter 337 is fixedly connected to the outer surface of the frame 31. One end of the right angle converter 337 is connected to one end of the first rotating shaft 321, and the other end of the right angle converter 337 is connected to one end of the rotating shaft 22. The irregular eccentric wheel 332 is connected to one end of the second rotating shaft 322. One end of the pull line 338 is fixedly connected to the movable rod 331, and the other end of the pull line 338 is fixedly connected to the duckbill mouth opener 5.

[0049] It should be noted that by adjusting the position of the two sets of irregular eccentric wheels 332, the two sets of duckbill mouth openers 5 can be linked to fall alternately to complete the transplanting.

[0050] It is understandable that the movable rod 331, the irregular eccentric wheel 332, and the crossbeam 334 are rotatably connected to the outer surface of the frame 31.

[0051] Specifically, the structure and connection relationship of the external drive transmission mechanism 33 are further explained. In use, the rotation of the first rotating shaft 321 synchronously drives the right-angle converter 337 to operate. The operation of the right-angle converter 337 synchronously drives the rotating shaft 22 to rotate. The rotation of the second rotating shaft 322 synchronously drives the irregular eccentric wheel 332 to rotate. The upward rotation of the irregular eccentric wheel 332 synchronously drives the movable pressure rod 336 to move downward along the outer surface of the stroke limit screw 333 and press down on the crossbeam 334. The downward movement of the crossbeam 334 synchronously drives the duck The duckbill opening device 5 descends and inserts into the ground. Simultaneously, the descent of the duckbill opening device 5 stretches the return spring 34. At the same time, the rotation of the irregular eccentric wheel 332 also drives the roller 335 and the movable rod 331 to move upward. The upward movement of the movable rod 331 simultaneously pulls one end of the pull line 338. After the pull line 338 is pulled, it simultaneously drives the duckbill opening device 5 to open, allowing the seedling to be planted and completing the transplanting. Similarly, the downward rotation of the irregular eccentric wheel 332 simultaneously drives the duckbill opening device 5 to move out of the ground and closes the duckbill opening device 5.

[0052] In one embodiment of this utility model, such as Figure 5As shown, the seedling cup assembly 2 also includes a triangular seedling cup assembly 6, which includes a triangular cup holder 61, a second transmission chain disc 62, a second transmission chain 63, a hydraulic transmission 64, and an adjustable protrusion seat 65.

[0053] The triangular cup holder 61 is bolted to the top of the machine body 1. The second transmission chain discs 62 are rotatably connected to the surface of the triangular cup holder 61 and are arranged in a triangle. The three sets of second transmission chain discs 62 are connected to each other by the second transmission chain 63. The conical seedling cups 25 are evenly fixedly connected to the surface of the second transmission chain 63. The hydraulic transmission 64 is fixedly connected to the surface of the triangular cup holder 61. The input end of the hydraulic transmission 64 passes through the bottom of the triangular cup holder 61 and is connected to one end of the right angle converter 337 through the flexible coupling. The output end of the hydraulic transmission 64 is connected to one end of the central shaft of one set of second transmission chain discs 62 through the flexible coupling. One end of the central shaft of the second transmission chain disc 62 corresponding to the position of the duckbill opener 5 passes through the bottom of the triangular cup holder 61 and is fixedly connected to an adjustable protrusion seat 65. The adjustable protrusion seat 65 is in contact with the screw on the surface of the conical seedling cup 25.

[0054] It should be noted that the flexible coupling described in this embodiment is not shown in the diagram.

[0055] It should also be noted that the second transmission chain 63 described in this embodiment is a double-row transmission chain (not shown in the figure), and the second transmission chain disc 62 is engaged with the lower row of the double-row transmission chain.

[0056] It should also be noted that an auxiliary tensioning device (not shown in the figure) is also included. This device consists of a tensioning chain disc and an adjusting arm. The tensioning chain disc is symmetrically arranged outside the second transmission chain disc 62 and is located outside the second transmission chain 63, forming a meshing connection with the upper row of the second transmission chain 63.

[0057] During operation, the upper drive chain of the second drive chain 63 is squeezed inward by two sets of tensioning chain discs, which in turn drives the lower drive chain of the second drive chain 63 to move synchronously. Through this action, the connection wrap angle between the second drive chain 63 and the active second drive chain disc 62 can reach ≥150°, and the wrap angle with other sets of second drive chain discs 62 can reach ≥120°. This design not only effectively ensures the stability of the connection and transmission, but also does not interfere with the movement of the conical seedling cup 25, ensuring smooth operation of the entire equipment. The position of the tensioning chain disc can be adjusted by the adjusting arm to ensure moderate tension, effectively achieve stable transmission, and avoid excessive compression that would lead to increased chain wear, resulting in good performance.

[0058] It should also be noted that the mounting block of the conical seedling cup 25 is fixed on the lower drive chain and is not connected to it.

[0059] The tensioning chain disc structure is in conflict.

[0060] Specifically, the structure and connection relationship of the triangular seedling cup assembly 6 are further explained. In use, the right-angle converter 337 drives the hydraulic transmission 64 to run synchronously through the flexible coupling. The hydraulic transmission 64 drives one set of second transmission chain discs 62 to rotate synchronously through the flexible coupling. The rotation of one set of second transmission chain discs 62 drives the other sets of second transmission chain discs 62 to rotate synchronously through the second transmission chain 63. Through the cooperation of the second transmission chain discs 62 and the second transmission chain 63, multiple sets of conical seedling cups 25 are moved synchronously. When the conical seedling cup 25 moves to the position of the adjustable protrusion 65 and contacts the adjustable protrusion 65, the conical seedling cup 25 automatically opens, and the seedlings inside automatically fall into the duckbill opening device 5 under the action of gravity.

[0061] In one embodiment of this utility model, such as Figures 6-7 As shown, the adjustable protruding seat 65 includes a mounting base 651, an upper translation rack 652, a lower translation rack 653, a synchronizing rack 654, and an adjusting handle 655. The mounting base 651 is fixedly connected to the outer surface of one end of the central shaft of the second transmission chain 62 by locking bolts. The upper translation rack 652 and the lower translation rack 653 are horizontally slidably connected to the inner wall of the mounting base 651 and are positioned vertically. The synchronizing rack 654 is rotatably connected to the mounting base. The inner wall of the mounting base 651 is located between the upper translation rack 652 and the lower translation rack 653. The synchronous rack 654 meshes with the teeth on the surfaces of the upper translation rack 652 and the lower translation rack 653, respectively. The adjusting handle 655 is rotatably connected to the bottom of the mounting base 651 and connected to the synchronous rack 654. The upper protruding side block 27 and the lower protruding side block 28 are fixedly connected to the outer surfaces of one end of the upper translation rack 652 and one end of the lower translation rack 653, respectively.

[0062] Specifically, the structure and connection relationship of the adjustable protrusion seat 65 are further explained. In use, the adjusting handle 655 is turned. The rotation of the adjusting handle 655 synchronously drives the synchronous gear 654 to rotate. The rotation of the synchronous gear 654 synchronously drives the upper translation gear 652 and the lower translation gear 653 to move inward or outward in sync, thereby adjusting the position of the upper protrusion block 27 and the lower protrusion block 28 to match the position of the screw, resulting in good performance.

[0063] In summary, the small transplanter of this utility model embodiment drives multiple actuators, such as the seedling cup assembly 2, the power wheel 4, and the duckbill mouth opener 5, through a single main drive system. This simplifies the mechanical structure, effectively reduces production costs, and significantly improves control accuracy and operating efficiency. At the same time, by optimizing power distribution and energy management strategies, the system can achieve more efficient energy utilization during operation, thereby reducing unnecessary energy consumption and conforming to the development trend of energy conservation and environmental protection.
